89-661: The organization now known as the International Brotherhood of Electrical Workers was founded in 1891, two years before George Westinghouse won the electric current wars by lighting the Chicago World's Columbian Exposition with alternating current , and before homes and businesses in the United States had begun receiving electricity. It is an international organization, based on the principle of collective bargaining. Its international president

178-499: A 1.5-MW 1200 rpm unit for the Hartford Electric Light Company . Westinghouse also developed steam turbines for maritime propulsion. The basic problem was that large turbines ran most efficiently at around 3000 rpm, while an efficient propeller operated only at about 100 rpm. This required reduction gearing, but designing reduction gearing that could operate at both high rpm and at high power

267-501: A 1959 Australian decision ("NRDC"), they believe that it is not possible to grasp the invention concept in a single rule. A British court once stated that the technical character test implies a "restatement of the problem in more imprecise terminology." In the United States, all patent applications are considered inventions. The statute explicitly says that the American invention concept includes discoveries (35 USC § 100(a)), contrary to

356-618: A barely competitive DC lighting system just different enough to get around Edison’s patents. In 1885 Westinghouse imported several Gaulard–Gibbs transformers and a Siemens AC generator , to begin experimenting with AC networks in Pittsburgh . Stanley, assisted by engineers Albert Schmid and Oliver B. Shallenberger , dramatically improved the Gaulard–Gibbs transformer design, creating the first practical and manufacturable transformer. In 1886, with Westinghouse's backing, Stanley installed

445-405: A better way to mine and extract copper from "lean" ores that were not particularly rich in the metal. Success is this venture would have helped him compete in the electrical businesses that used much copper. He was unsuccessful in this project: no new copper reduction process was found and the mine was not profitable. He had founded the town of Duquesne to use as his company headquarters; it is now

534-503: A building to electrical exhibits. It was a key event in the history of AC power, as Westinghouse demonstrated the safety, reliability, and efficiency of a fully integrated alternating current system to the American public. Westinghouse's demonstration of their ability to build a complete AC system at the Columbian Exposition was instrumental in the company getting the contract for building a two-phase AC generating system,

623-501: A compressed air system. His first braking system used an air compressor and an air reservoir in the locomotive, with a single compressed air pipe running the length of the train and with flexible connections between cars. That line controlled the brakes, allowing the engineer to apply and release the brakes simultaneously on all cars. A charter for what would eventually become the Westinghouse Air Brake Company

712-472: A deployed system capable of transmitting electricity for many miles near London, Turin, and Rome. They had found that AC electricity could be "stepped up" in voltage by a transformer for transmission and then "stepped down" by another transformer for lower voltage consumer use. This innovation made it possible for large, centralized power plants to generate electricity and supply it over long distances to both cities and places with more dispersed populations. This

801-456: A ghost town. Duquesne grew to over 1,000 residents and the mine reached its peak production in the mid-1910s. Westinghouse also began to work on heat pumps that could provide heating and cooling. When Westinghouse claimed he was after a perpetual motion machine , the British physicist William Thomson ( Lord Kelvin ), one of his many correspondents, told him that such a machine would violate

890-567: A hydroelectric AC power plant, the Ames Hydroelectric Generating Plant near Ophir, Colorado which supplied AC power to the Gold King Mine 3.5 miles away. This was the first successful demonstration of long-distance transmission of industrial-grade alternating current power and utilized two 100 hp Westinghouse alternators, one working as a generator producing 3,000-volt, 133-Hertz, single-phase AC, and

979-537: A lot of attention, in part because of a spectacular flaming blowout of the Haymaker Well in 1878. After visiting the well and recognizing its commercial potential, he undertook drilling for gas on his estate Solitude (today's Westinghouse Park ) in Pittsburgh. Early in the morning of May 21, 1884, the drilling crew struck a pocket of gas at a depth of 1500 feet, and the resulting blast of dirt and water blew

1068-480: A new kind of abstraction by dripping, pouring, splashing and splattering paint onto un-stretched canvas lying on the floor. Inventive tools of the artist's trade also produced advances in creativity. Impressionist painting became possible because of newly invented collapsible, resealable metal paint tubes that facilitated spontaneous painting outdoors. Inventions originally created in the form of artwork can also develop other uses, e.g. Alexander Calder's mobile, which

1157-707: A slow decline throughout the rest of the 1970s and the 1980s, but have since stabilized. One major loss of membership for the IBEW came about because of the court-ordered breakup at the end of 1982 of AT&T , where the IBEW was heavily organized among both telephone workers and in AT&;T's manufacturing facilities. In 1988, 30 percent of American construction work was unionized while the IBEW had 40 percent of electrical-related construction. Membership as of 2020 stands at about 775,000, according to their official website. The IBEW supports new construction of nuclear power plants in

1246-609: A spreading public perception that the high voltages used in AC distribution were unsafe and deadly. Edison even suggested that a Westinghouse AC generator should be used in the State of New York's new electric chair . Westinghouse also had to deal with another AC rival, the Thomson-Houston Electric Company , which had constructed 22 power stations by the end of 1887 and by 1889 it had acquired another competitor,

1335-665: A talent for machinery and business. He was encouraged by his father and was assigned tasks in the Westinghouse Company workshop. The company produced farm equipment such as the Westinghouse Farm Engine . At the outbreak of the Civil War in April 1861, the then 14-year-old attempted to run away from home to enlist, but was stopped by his father. In June 1863 his parents allowed him to enlist, first in

1424-434: A train braking system using compressed air revolutionized the railroad industry around the world. He founded the Westinghouse Air Brake Company in 1869. He and his engineers also developed track-switching and signaling systems, which lead to the founding of the company Union Switch & Signal in 1881. In the early 1880s, he developed inventions for the safe production, transmission, and use of natural gas. This sparked

1513-614: A train, and they married in August of that year. They were married for 47 years, and had one son, George Westinghouse III, who in turn had six children. From 1871, George and Marguerite Westinghouse maintained a large home in Pittsburgh called Solitude, building up from an existing house on land purchased by George in 1871. They were part of a social class of very rich local industrialists and money managers including neighbors and associates Henry Clay Frick , Henry J. Heinz , William Thaw , Andrew Mellon , and Richard Beatty Mellon , and

1602-517: A while. In 1891, Westinghouse's company was in trouble. The near collapse of Barings Bank in London triggered the financial panic of 1890 , causing investors to call in their loans. The sudden cash shortage forced the company to refinance its debts. The new lead lenders demanded that Westinghouse cut back on what looked to them like his excessive spending on the acquisition of other companies, research, and patents. Also in 1891, Westinghouse built

1691-701: Is Kenneth W. Cooper and is affiliated with the AFL–CIO . The beginnings of the IBEW were in the Electrical Wiremen and Linemen's Union No. 5221, founded in St. Louis , Missouri in 1890. By 1891, after sufficient interest was shown in a national union, a convention was held on November 21, 1891, in St. Louis. At the convention, the IBEW, then known as the National Brotherhood of Electrical Workers (NBEW),

1780-449: Is also an important component of artistic and design creativity . Inventions often extend the boundaries of human knowledge, experience or capability. Inventions are of three kinds: scientific-technological (including medicine), sociopolitical (including economics and law), and humanistic, or cultural. Scientific-technological inventions include railroads, aviation , vaccination , hybridization, antibiotics , astronautics, holography ,

1869-427: Is also an important legal concept and central to patent law systems worldwide. As is often the case for legal concepts, its legal meaning is slightly different from common usage of the word. Additionally, the legal concept of invention is quite different in American and European patent law. In Europe, the first test a patent application must pass is, "Is this an invention?" If it is, subsequent questions are whether it

1958-494: Is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence , the term "inventor" no longer exclusively applies to an occupation (see human computers ). Some inventions can be patented. The system of patents was established to encourage inventors by granting limited-term, limited monopoly on inventions determined to be sufficiently novel, non-obvious, and useful . A patent legally protects

2047-623: Is new and sufficiently inventive. The implication—counter-intuitively—is that a legal invention is not inherently novel. Whether a patent application relates to an invention is governed by Article 52 of the European Patent Convention, that excludes, e.g., discoveries as such and software as such . The EPO Boards of Appeal decided that the technical character of an application is decisive for it to represent an invention, following an age-old Italian and German tradition. British courts do not agree with this interpretation. Following

2136-465: Is now commonly used over babies' cribs. Funds generated from patents on inventions in art, design and architecture can support the realization of the invention or other creative work. Frédéric Auguste Bartholdi 's 1879 design patent on the Statue of Liberty helped fund the famous statue because it covered small replicas, including those sold as souvenirs. The timeline for invention in the arts lists

2225-482: Is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word inventor comes from the Latin verb invenire , invent- , to find. Although inventing

2314-541: The Adams Power Plant , at Niagara Falls, NY, in 1895. The company was subcontracted to build ten 5,000 horsepower (3,700 kW) 25 Hz AC generators at this plant. Westinghouse's Niagara Power Station No. 1, as it was then called, remained in operation in the Niagara transformer house until the plant closed in 1961. At the same time, a contract to build the three-phase AC distribution system

2403-895: The Baháʼí Faith . Some of these disciplines, genres, and trends may seem to have existed eternally or to have emerged spontaneously of their own accord, but most of them have had inventors. Ideas for an invention may be developed on paper or on a computer, by writing or drawing, by trial and error , by making models, by experimenting , by testing and/or by making the invention in its whole form. Brainstorming also can spark new ideas for an invention. Collaborative creative processes are frequently used by engineers, designers, architects and scientists. Co-inventors are frequently named on patents. In addition, many inventors keep records of their working process – notebooks , photos, etc., including Leonardo da Vinci , Galileo Galilei , Evangelista Torricelli , Thomas Jefferson and Albert Einstein . In

2492-591: The Brush Electric Company . Thomson-Houston was expanding its business while trying to avoid patent conflicts with Westinghouse, arranging deals such as agreements over lighting company territory, paying royalties to use the Stanley transformer patent, and allowing Westinghouse to use its Sawyer–Man incandescent bulb patent. In 1890, the Edison company, in collusion with Thomson-Houston, arranged for

2581-651: The Grand Army of the Republic , a fraternal organization of Union Civil War veterans, held a week-long convention in Pittsburgh. George Westinghouse, being a veteran himself, hosted an evening of dinner and entertainment for more than 5,000 attendees at the newly constructed, but not yet active main buildings of the Westinghouse Electric and Manufacturing Company in East Pittsburgh. He took on

2670-637: The Rankine Generating Station , also known as The Canadian Niagara Power Generating Station, the Canadians contracted with Westinghouse for eleven 25 Hertz generators of the same Tesla-inspired design, rated for a total generating capacity of 100 MW. That facility opened in 1905 in Niagara Falls, Ontario. Despite continuing success in his other businesses, Westinghouse's main interest shifted to electric power. At

2759-742: The United Nations , the European Union , and the Universal Declaration of Human Rights , as well as movements such as socialism , Zionism , suffragism , feminism , and animal-rights veganism. Humanistic inventions encompass culture in its entirety and are as transformative and important as any in the sciences, although people tend to take them for granted. In the domain of linguistics, for example, many alphabets have been inventions, as are all neologisms ( Shakespeare invented about 1,700 words). Literary inventions include

2848-593: The alternating current system". George Westinghouse was born in 1846 in the village of Central Bridge, New York (see George Westinghouse Jr. Birthplace and Boyhood Home ), the son of Emeline (Vedder) and George Westinghouse Sr., a farmer and machine shop owner. The Westinghouse ancestors came from Westphalia in Germany, moving first to England and eventually emigrating to the US. The family name had been anglicized from Westinghausen. From his youth, Westinghouse displayed

2937-428: The parachute became more useful once powered flight was a reality. Invention is often a creative process . An open and curious mind allows an inventor to see beyond what is known. Seeing a new possibility, connection or relationship can spark an invention. Inventive thinking frequently involves combining concepts or elements from different realms that would not normally be put together. Sometimes inventors disregard

3026-418: The "Westinghouse Electric Corporation". The Westinghouse company installed thirty more AC-lighting systems within a year, and by the end of 1887 it had 68 alternating current power stations compared to 121 DC-based stations Edison had installed over seven years. This competition with Edison led, in the late 1880s, to what became known as the " war of currents ". Thomas Edison and his company joined and promoted

3115-536: The "White City" at the 1893 Columbian Exposition in Chicago. The company went on to install the world's first large-scale, AC power generation plant at Niagara Falls, New York, which opened in August 1895. Ironically, among many other honors, Westinghouse received the 1911 Edison Medal of the American Institute of Electrical Engineers "for meritorious achievement in connection with the development of

3204-479: The "abstract idea" test, which suffers from abstractness itself, but none have succeeded. The last attempt so far was the "machine or transformation" test, but the U.S. Supreme Court decided in 2010 that it is merely an indication at best. In India, invention means a new product or process that involves an inventive step, and capable of being made or used in an industry. Whereas, "new invention" means any invention that has not been anticipated in any prior art or used in

3293-1048: The 12th Regiment of the New York National Guard and then in the 16th Regiment of the New York Cavalry. He earned a promotion to the rank of corporal before being honorably discharged in November 1863. A month later he joined the Union Navy. He served as an Acting Third Assistant Engineer on the gunboat USS  Muscoota and then on the ship USS  Stars and Stripes through the end of the war. These ships were used to blockade Southern port cities. After his discharge in August 1865, Westinghouse returned to his family and enrolled at Union College in Schenectady, but he quickly lost interest and dropped out during his first term. He further developed his skills in his father's company shop. Westinghouse

3382-537: The 1910s, when two rival groups each claimed to be the duly elected leaders of the union. In 1919, as many employers were trying to drive unions out of the workplace through a national open shop campaign, the union agreed to form the Council on Industrial Relations, a bipartite body made up of equal numbers of management and union representatives with the power to resolve any collective bargaining disputes. That body still functions today, and has largely resolved strikes in

3471-478: The British engineer Charles Algernon Parsons began experimenting with steam turbines , starting with a 10-horsepower (7.5 kW) turbine. In 1895, Westinghouse bought rights to the Parsons turbine, and his engineers improved its technology and increased its scale. In 1898, Westinghouse demonstrated a 300-kilowatt generating unit, replacing reciprocating engines in his air-brake factory. The next year, he installed

3560-603: The Edison patent design. By the beginning of 1893, Westinghouse engineer Benjamin Lamme had made great progress in developing an efficient version of Tesla's induction motor. In that work he was aided by his sister and fellow Westinghouse engineer Bertha Lamme Feicht . Westinghouse Electric started branding their complete polyphase AC system as the "Tesla Polyphase System", announcing Tesla's patents gave them patent priority over other AC systems and stating their intention to sue any patent infringers. This World's Fair devoted

3649-489: The European invention concept. The European invention concept corresponds to the American "patentable subject matter" concept: the first test a patent application is submitted to. While the statute (35 USC § 101) virtually poses no limits to patenting whatsoever, courts have decided in binding precedents that abstract ideas, natural phenomena and laws of nature are not patentable. Various attempts have been made to substantiate

3738-599: The IBEW conducts apprenticeship programs for electricians, linemen, and VDV (voice, data, and video) installers (who install low-voltage wiring such as computer networks), in conjunction with the National Electrical Contractors Association , under the auspices of the National Joint Apprenticeship and Training Committee (NJATC), which allows apprentices to "earn while you learn." In Canadian jurisdictions,

3827-588: The IBEW does not deliver apprenticeship training, but does conduct supplemental training for government trained apprentices and journeypersons, often at little or no cost to its members. The IBEW local 353 Toronto requires all apprentices to be registered with the JAC (Joint Apprenticeship Council) for a number of safety courses, pre-apprenticeship training, pre-trade school courses, supplementary training, and pre-exam courses. The IBEW's membership peaked in 1972 at approximately 1 million members. The membership numbers were in

3916-756: The IBEW's jurisdiction in the construction industry. In September 1941, the National Apprenticeship Standards for the Electrical Construction Industry, a joint effort among the IBEW, the National Electrical Contractors Association , and the Federal Committee on Apprenticeship, were established. The IBEW added additional training programs and courses as needed to keep up with new technologies, including an industrial electronics course in 1959 and an industrial nuclear power course in 1966. Today,

4005-863: The Nobel Prize in 2000 and has led to innovative lighting, display screens, wallpaper and much more (see conductive polymer , and organic light-emitting diode or OLED ). Invention is often an exploratory process with an uncertain or unknown outcome. There are failures as well as successes. Inspiration can start the process, but no matter how complete the initial idea, inventions typically must be developed. Inventors may, for example, try to improve something by making it more effective, healthier, faster, more efficient, easier to use, serve more purposes, longer lasting, cheaper, more ecologically friendly, or aesthetically different, lighter weight, more ergonomic , structurally different, with new light or color properties, etc. In economic theory , inventions are one of

4094-560: The United States. George Westinghouse George Westinghouse Jr. (October 6, 1846 – March 12, 1914) was a prolific American inventor , engineer , and entrepreneurial industrialist based in Pittsburgh , Pennsylvania . He is best known for his creation of the railway air brake and for being a pioneer in the development and use of alternating current (AC) electrical power distribution . During his career, he received 362 patents for his inventions and established 61 companies, many of which still exist today. His invention of

4183-719: The Westinghouses leased and then in 1901 purchased the Blaine House mansion in Washington D.C. Marguerite Westinghouse was reputed to host frequent and lavish entertainments there. In 1918, his former Pittsburgh home, Solitude, was razed and the land given to the City of Pittsburgh to establish Westinghouse Park . The house in Erskine Park was sold by the family in 1917 and subsequently demolished. Earlier in 1894,

4272-621: The aftermath of a collision where engineers on two trains, approaching each other on the same track, had seen each other but were unable to stop their trains in time due to the existing brake systems. At that time, brakemen had to run along catwalks on the top of the cars, manually applying the brakes. Coordinating that process was tricky and dangerous. It also meant trains could not exceed ten cars in length, and thousands of brakemen died or were maimed each year. In 1869, at age 23, Westinghouse first publicly demonstrated his revolutionary new railroad braking system in Pittsburgh. It stopped trains using

4361-829: The atomic bomb, computing, the Internet , and the smartphone. Sociopolitical inventions comprise new laws, institutions, and procedures that change modes of social behavior and establish new forms of human interaction and organization. Examples include the British Parliament , the US Constitution , the Manchester (UK) General Union of Trades, the Boy Scouts, the Red Cross , the Olympic Games ,

4450-487: The boundaries between distinctly separate territories or fields. Several concepts may be considered when thinking about invention. Play may lead to invention. Childhood curiosity, experimentation, and imagination can develop one's play instinct. Inventors feel the need to play with things that interest them, and to explore, and this internal drive brings about novel creations. Sometimes inventions and ideas may seem to arise spontaneously while daydreaming , especially when

4539-469: The brothers Andrew Carnegie and Thomas Carnegie . Their guests included Nicola Tesla , Lord Kelvin , and congressman (and future president) William McKinley . By 1893, they had constructed Erskine Park in Lenox, Massachusetts , which they used as a summer home, in part as a respite from the gritty industrial environment of Pittsburgh. It was named for the family of Marguerite's grandparents. In 1898,

SECTION 50

4628-554: The case of polytetrafluoroethylene (Teflon). Insight can also be a vital element of invention. Such inventive insights may begin with questions, doubt or a hunch . It may begin by recognizing that something unusual or accidental may be useful or that it could open a new avenue for exploration. For example, the odd metallic color of plastic made by accidentally adding a thousand times too much catalyst led scientists to explore its metal-like properties, inventing electrically conductive plastic and light emitting plastic—an invention that won

4717-517: The chief examples of " positive externalities ", a beneficial side effect that falls on those outside a transaction or activity. One of the central concepts of economics is that externalities should be internalized—unless some of the benefits of this positive externality can be captured by the parties, the parties are under-rewarded for their inventions, and systematic under-rewarding leads to under-investment in activities that lead to inventions. The patent system captures those positive externalities for

4806-482: The conscious mind turns away from the subject or problem when the inventor's focus is on something else, or while relaxing or sleeping. A novel idea may come in a flash—a Eureka ! moment. For example, after years of working to figure out the general theory of relativity, the solution came to Einstein suddenly in a dream "like a giant die making an indelible impress, a huge map of the universe outlined itself in one clear vision". Inventions can also be accidental, such as in

4895-473: The country or anywhere in the world. Invention has a long and important history in the arts . Inventive thinking has always played a vital role in the creative process . While some inventions in the arts are patentable , others are not because they cannot fulfill the strict requirements governments have established for granting them. (see patent ). Some inventions in art include the: Likewise, Jackson Pollock invented an entirely new form of painting and

4984-532: The creation of a whole new energy industry. During this same period, Westinghouse recognized the potential of using alternating current (AC) for electric power distribution. In 1886, he founded the Westinghouse Electric Corporation . Westinghouse's electric business directly competed with Thomas Edison 's, who was promoting direct current (DC) electricity. Westinghouse Electric won the contract to showcase its AC system to illuminate

5073-407: The dignity of man and part of his intellectual property. Westinghouse, unlike Edison, did not put his name on all company patents as co-inventor. Westinghouse was not in favor of labor unionization. He did not reject workers who belonged to a union, but he did not like collective bargaining arrangements where his workers might strike for issues not related to conditions at his own factories. There

5162-413: The early 1880s, Westinghouse's interest in railroad switching and natural gas distribution led him to become involve in the then-new field of electrical power distribution. Electric lighting of streets using arc lighting was already a growing business with many companies building systems powered by either locally generated direct current (DC) or alternating current (AC). At the same time, Thomas Edison

5251-845: The epic, tragedy , comedy, the novel , the sonnet , the Renaissance , neoclassicism, Romanticism , Symbolism , Aestheticism, Socialist Realism , Surrealism , postmodernism , and (according to Freud) psychoanalysis . Among the inventions of artists and musicians are oil painting, printmaking, photography , cinema , musical tonality, atonality, jazz , rock, opera , and the symphony orchestra. Philosophers have invented logic (several times), dialectics , idealism, materialism, utopia , anarchism , semiotics , phenomenology , behaviorism , positivism , pragmatism , and deconstruction . Religious thinkers are responsible for such inventions as monotheism , pantheism , Methodism , Mormonism , iconoclasm, puritanism , deism , secularism, ecumenism, and

5340-399: The expenses of the necessary building preparations and all the expenses of transporting people to and from the site by rail. Inventor An invention is a unique or novel device , method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea

5429-449: The first electric chair to be powered with a Westinghouse AC generator. Westinghouse tried to block this move by hiring the best lawyer of the day to (unsuccessfully) defend William Kemmler , the first man scheduled to die in the chair. The War of Currents ended in 1892 when financier J. P. Morgan forced Edison General Electric to switch to AC power and then pushed Edison out of the company he had founded. Edison General Electric company

5518-468: The first multiple-voltage AC power system in Great Barrington, Massachusetts . The demonstration lighting system was driven by a hydroelectric generator that produced 500 volts AC, which was then stepped down to 100 volts to light incandescent bulbs in homes and businesses. That same year, Westinghouse founded the " Westinghouse Electric & Manufacturing Company "; in 1889 he renamed it

5607-510: The intellectual property rights of the inventor and legally recognizes that a claimed invention is actually an invention. The rules and requirements for patenting an invention vary by country and the process of obtaining a patent is often expensive. Another meaning of invention is cultural invention , which is an innovative set of useful social behaviours adopted by people and passed on to others. The Institute for Social Inventions collected many such ideas in magazines and books. Invention

5696-441: The inventor or other patent owner so that the economy as a whole invests an optimum amount of resources in the invention process. In contrast to invention, innovation is the implementation of a creative idea that specifically leads to greater value or usefulness. That is, while an invention may be useless or have no value yet still be an invention, an innovation must have some sort of value, typically economic. The term invention

5785-433: The laws of thermodynamics . Westinghouse replied that might be the case, but it made no difference. If he couldn't build a perpetual motion machine, he would still have a heat pump system that he could patent and sell. After the broader introduction of the automobile , Westinghouse invented a compressed air shock absorber for their suspension systems. The shock absorber was the last of the 362 patents he received, and it

5874-400: The lines kept the brakes disengaged. An air reservoir was also placed on each car. With the improved design, any interruption or break in the line automatically caused the train to stop. During the next decade, building on his earliest inventions, Westinghouse expanded his interest to railway signaling and track-switching systems. Previously, signaling relied on oil lamps and track switching

5963-415: The mind is free from its usual concerns. For example, both J. K. Rowling (the creator of Harry Potter ) and Frank Hornby (the inventor of Meccano ) first had their ideas while on train journeys. In contrast, the successful aerospace engineer Max Munk advocated "aimful thinking". To invent is to see anew. Inventors often envision a new idea, seeing it in their mind's eye . New ideas can arise when

6052-402: The most notable artistic inventors. Historically, women in many regions have been unrecognised for their inventive contributions (except Russia and France ), despite being the sole inventor or co-inventor in inventions, including highly notable inventions. Notable examples include Margaret Knight who faced significant challenges in receiving credit for her inventions; Elizabeth Magie who

6141-497: The next three years, he developed devices and secured more than 30 patents for this technology. He used the Philadelphia Company to develop gas wells and to promote gas usage both for commercial and residential purposes. By 1886, the Philadelphia Company owned 58 wells and 184 miles of distribution piping in the Pittsburgh area, and by 1887, it served over 12,000 private homes and 582 industrial customers throughout

6230-478: The other used as an AC motor. In May 1892, Westinghouse Electric won the bid to power and illuminate the 1893 World's Columbian Exposition in Chicago with alternating current, substantially underbidding General Electric to get the contract. To meet the contract's demands, he had to quickly develop a new type of incandescent lightbulb based on the Sawyer–Man patent he had obtained, ensuring it did not infringe on

6319-409: The outset, the available generating sources were hydro turbines where falling water was available, and reciprocating steam engines where it was not. Westinghouse felt that existing reciprocating steam engines were clumsy and inefficient, and he wanted to develop rotating engines that would be more elegant. His first patent had been a rotary steam engine, but it proved impractical at the time. In 1884,

6408-445: The process of developing an invention, the initial idea may change. The invention may become simpler, more practical, it may expand, or it may even morph into something totally different. Working on one invention can lead to others too. History shows that turning the concept of an invention into a working device is not always swift or direct. Inventions may also become more useful after time passes and other changes occur. For example,

6497-429: The project needed was awarded to General Electric. The early to mid-1890s saw General Electric, backed by financier J. P. Morgan , engaged in costly takeover attempts and patent battles with Westinghouse Electric. The competition was so costly that in 1896 a patent-sharing agreement was signed between the two companies. The agreement stayed in effect until 1911. Following the success of the first Niagara Falls plant,

6586-427: The rights to inventor Nikola Tesla 's brushless AC induction motor along with patents for a new type of electric power distribution, polyphase alternating current. The acquisition of a feasible AC motor gave Westinghouse a key patented element for his system, but the financial strain of buying up patents and hiring the engineers needed to build it meant that the development of Tesla's motor had to be put on hold for

6675-490: The state. In 1889, as his involvement with the generation and distribution of electricity was surging, Westinghouse resigned as president of the Philadelphia Company, but he remained on its board. Growth in the natural gas business slowed in the 1890s, hindered by supply problems and ongoing safety concerns related to gas distribution in homes and businesses. However, the Philadelphia Company continued to grow, spawning enterprises such as Equitable Gas and Duquesne Light . In

6764-494: The time, especially in contrast to the conditions endured by workers in the nearby steel mills. Westinghouse was broadly admired by his workers. Privately, they referred to him as "the Old Man". An indication of his progressive attitude was that when Westinghouse engineers invented things, they were allowed to keep their names on the patents, though assigning rights to use them to the company. Westinghouse viewed this as part of

6853-461: The top off the derrick. It took Westinghouse a week to devise a method to cap the flow of gas. He was encouraged to develop a system to deliver gas to heat and light area homes and businesses. Eventually, several natural gas derricks towered above his estate's Victorian-era gardens. In modern times there is no above-ground trace left of these derricks. That year, Westinghouse acquired a dormant utility charter for "The Philadelphia Company", and over

6942-409: Was a huge advantage over the low voltage DC systems being marketed by Edison ’s electric utility, which limited generating stations to a transmission range of about a mile due to losses cause by the low voltages and high currents used. Westinghouse recognized AC's potential to achieve greater economies of scale as a way to create a truly competitive electrical system, instead of simply piecing together

7031-692: Was also the headquarters of several companies, particularly Westinghouse Air Brake . Westinghouse Electric and Manufacturing was located a mile further down the Turtle Creek valley east of Pittsburgh. The worker houses were outfitted with running water, electricity, gas, and often space for small gardens. Homeownership was facilitated through periodic salary deductions. There was a pension and an insurance system. Factories were well-lit, ventilated, and were outfitted with medical facilities and personnel for treating injuries. All these accommodations, at Westinghouse's expense, were considered highly innovative at

7120-497: Was awarded posthumously, four years after his death. Westinghouse was the first industrial employer in the United States to give workers a five-and-a half day work week, starting in June 1881. Saturdays were made half holidays to promote community involvement and personal development. Westinghouse had observed the practice while visiting England. The planned community of Wilmerding , PA was home to many Westinghouse employees, and it

7209-539: Was difficult since any slight misalignment would shake the powertrain to pieces. Westinghouse and his engineers invented an automatic self-alignment system that finally made turbine power practical for large vessels. In 1889, Westinghouse purchased several mining claims in the Patagonia Mountains of southeastern Arizona and formed the Duquesne Mining & Reduction Company. He hoped to invent

7298-457: Was filed in July of that year. Although the system was successful, as demonstrated when it prevented a serious mishap in front of assembled witnesses, it was hardly fail-safe. Any rupture or disconnection in the air line left the train without brakes. Over the next two years, Westinghouse and his engineers addressed the problem by inverting the process, designing valves so that constant pressure in

7387-566: Was just 19 when he received his first patent for a rotary steam engine . At age 21, he invented a car replacer, a device used to guide derailed railroad cars back onto the tracks, and a reversible "frog" , a rail junction piece used to switch trains between different tracks. In 1868, Westinghouse moved with his wife to Pittsburgh, Pennsylvania, to access better and less expensive steel for the manufacture of his railroad frogs, and there he began to develop his recently invented railroad air brake concept. During his travels, Westinghouse had witnessed

7476-522: Was launching the first DC electric utility designed to light homes and businesses with his patented incandescent bulb . In 1884, Westinghouse began developing his own DC domestic lighting system and hired physicist William Stanley to help work on it. In 1885, Westinghouse became aware of the concept of an electrical transformer introduced by Frenchman Lucien Gaulard and Englishman John Gibbs. Guido Pantaleoni, an Italian engineer in his employ, alerted Westinghouse to their aready-patented transformer and

7565-568: Was merged with the Thomson-Houston Electric Company to form General Electric , a conglomerate controlled by the board of Thomson-Houston. During this period, Westinghouse continued to pour money and engineering resources into the goal of building a completely integrated AC system — obtaining the Sawyer–Man lamp by buying Consolidated Electric Light, and developing components such as an induction meter , and obtaining

7654-484: Was not credited for her invention of the game of Monopoly ; and among other such examples, Chien-Shiung Wu whose male colleagues alone were awarded the Nobel Prize for their joint contributions to physics. Societal prejudice, institutional, educational and often legal patent barriers have both played a role in the gender invention gap. For example, although there could be found female patenters in US patent Office who also are likely to be helpful in their experience, still

7743-563: Was officially formed. The American Federation of Labor gave the NBEW a charter as an AFL affiliate on December 7, 1891. The union's official journal, The Electrical Worker , was first published on January 15, 1893, and has been published ever since. At the 1899 convention in Pittsburgh , Pennsylvania , the union's name was officially changed to the International Brotherhood of Electrical Workers. The union went through lean times in its early years, then struggled through six years of schism during

7832-581: Was only one strike at any Westinghouse company while he was in charge. It was a 1903 action at Westinghouse Machine Company, which was rushing to illuminate the 1904 St. Louis Worlds Fair . Westinghouse responded by immediately hiring replacements for those employees who walked out. Despite that action, American labor and union organizer Samuel Gompers is reputed to have said "If all business leaders and moguls treated their employees as well as George Westinghouse, there’d be no need for any labor unions". In 1867, Westinghouse met Marguerite Erskine Walker on

7921-486: Was performed manually. Westinghouse's designs changed all that. In 1882, Westinghouse founded the Union Switch and Signal Company to manufacture, market, install, and maintain these innovative control systems, which were eventually adopted by railroads around the world. By 1883, Westinghouse had become interested in natural gas. Gas had recently been discovered in nearby Murrysville , Pennsylvania, and it attracted
