84-560: A door handle or doorknob is a handle used to open or close a door . Door handles can be found on all types of doors including exterior doors of residential and commercial buildings , internal doors, cupboard doors and vehicle doors. There are many designs of door handle, depending on the appropriate use. A large number of handles, particularly for commercial and residential doors, incorporate latching or locking mechanisms or are manufactured to fit to standardised door locking or latching mechanisms. The most common types of door handle are
168-493: A heat wave during the summer, no mass health crises occurred. Philadelphia passed an ordinance that authorized Mayor William S. Stokley to appoint 500 men as Centennial Guards for the exposition. Among soldiers and local men hired by the city was Frank Geyer , best known for investigating one of America's first serial killers, H. H. Holmes . Centennial Guards policed exhibits, kept the peace, reunited lost children, and received, recorded, and when possible, returned lost items,
252-458: A balcony whose door has an outside shutter, a special door handle is used on the outer side. The protruding part of such handle (usually ring-shaped) can be folded sideways, so that the shutter can be fully closed without being obstructed by the door handle. These doors are referenced in pop culture such as Interstellar and A Dolphin Tale , as they are culturally significant in certain regions of
336-544: A brick and marble foundation and was 383 ft (117 m) long, 193 ft (59 m) wide, and 68 ft (21 m) tall. The building was designed in the Moorish style and intended as a tribute to the Crystal Palace of London 's Great Exhibition of 1851. Inside, nurserymen, florists, and landscape architects exhibited a variety of tropical plants, garden equipment, and garden plans. In dramatic fashion,
420-660: A combined handle/key. Although available, these key lockable doors were relatively rare. Houses were almost always occupied so most lockable doors would feature a sliding bolt or a drop-in bar that allowed the building to be locked from the inside. The bolt or bar bracket acted as a handle. Although interior doors were less common in Rome than in modern buildings, the Romans had recognisably modern interior doors including door handles. Doors excavated from Lake Nemi and dated to around 1st century CE feature knob-shaped handles. In Asia, China by
504-407: A decorative flourish. The plate on the edge of a door (where a bolt or door plunger protrudes) is called the "faceplate"; opposite on the jamb is the "latchplate", creating or reinforcing the hole receiving a latch, bolt, or plunger. The location of the door handle along the horizontal axis on the door can vary between a few inches or centimeters away from the edge of the door to the exact center of
588-500: A fence nearly three miles long. There were five main buildings in the exposition. They were the Main Exhibition Building, Memorial Hall, Machinery Hall, Agricultural Hall, and Horticultural Hall. Apart from these buildings, there were separate buildings for state, federal, foreign, corporate, and public comfort buildings. This strategy of numerous buildings in one exposition set it apart from the previous fairs around
672-660: A great-granddaughter of Benjamin Franklin , as president. In its first few months, the group raised $ 40,000. When the group learned the planning commission was not doing much to display the work of women, it raised an additional $ 30,000 for a women's exhibition building. In 1873, the Centennial Commission named Alfred T. Goshorn as the director general of the Exposition. The Fairmount Park Commission set aside 450 acres (1.8 km ) of West Fairmount Park for
756-665: A greater range of ergonomic issues. Centennial Exposition The Centennial International Exhibition , officially the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine , was held in Philadelphia , Pennsylvania, from May 10 to November 10, 1876. It was the first official world's fair to be held in the United States and coincided with the centennial anniversary of
840-581: A handle and subsequently touches their eyes, nose or mouth. However, some materials, e.g. brass , copper and silver , are slowly poisonous to many germs . The exact mechanism is not known, but is commonly thought to be via the oligodynamic effect , perhaps by some other electrostatic effect. Brass and copper, for example, disinfect themselves of many door handle bacteria within eight hours. Other materials such as glass , porcelain , stainless steel and aluminium do not have this effect. To avoid hand contact, some door handles are designed to be operated by
924-412: A knob, as the lever does not require a tight grip. Levers are also beneficial on doors with narrow stile widths where the reduced backset leaves insufficient space to comfortably turn a doorknob. Most household door handles use a simple mechanism with a screw-style axle (called a spindle) that has at least one flat side, which is passed through the door jigger, leaving some length exposed on each side of

But after the exposition ended, the federal government sued to have the money returned, and the United States Supreme Court ultimately forced repayment. John Welsh enlisted help from the women of Philadelphia who had helped him in the Great Sanitary Fair. A Women's Centennial Executive Committee was formed with Elizabeth Duane Gillespie,
1092-492: A major part of the industry thanks to improvements in the pressed glass manufacturing process. Cut glass knobs were also popular from the time of the Centennial Exposition to about 1910. From the early 20th century architects and designers started to take serious interest in door handles as part of a comprehensive vision of spaces for living. In 1927 Wittgenstein famously designed a door handle which has become
1176-472: A pavilion devoted entirely to the artistic and industrial pursuits of their gender. They had to build their own structure because they lost their spot in one of the larger pavilions (the Main Building) due to an unexpected increase in the participation of foreign countries. Their aim was to employ only women in the construction of the pavilion and even to power it, and they succeeded with the exception of
1260-461: A popular means for justifying female autonomy outside of the home by demonstrating to visitors the many ways women were making a profitable living. Exhibits demonstrated positive achievements and women's influence in domains such as industrial and fine arts (wood-carvings, furniture-making, and ceramics), fancy articles (clothing and woven goods), and philanthropy as well as philosophy, science, medicine, education, and literature. Mexico participated in
1344-606: A prototype for curved tubular handles since then. Emerson wrote of handles in his " The American Scholar " address. Peter Behrens , Walter Gropius and Antoni Gaudi all produced handle designs, many of which continue to be manufactured. While aesthetic design, cost of manufacture and functionality remain primary drivers of door handle design, the 21st century has seen additional considerations introduced. In particular, considerations of infection control {see section below} and accessibility have become increasingly important since around 2000. The Coronavirus pandemic has contributed to
1428-506: A rapid development of new handle designs including foot-operated handles and handles that can be operated by the user's forearm. Escutcheon plates , also known as back plates , are used behind door handles, drawer pulls , surrounding keyholes and separate locks, and other similar purposes. These may be plain or fancy, embellished in any form, and serve variously to protect surrounding surfaces, conceal (and render tamperproof) important attachment fasteners, cover uneven rough openings, and add
1512-558: A rose or escutcheon plate. Until about 1830 door handle manufacture in the western world was almost entirely European. In 1838 the US was importing between 80 and 95% of its door handles. Between 1830 and 1876, the date of the Centennial Exposition , door handle manufacture grew rapidly in the US; more than 100 patents were filed for door handle and doorknob improvements in that time. This period also saw glass doorknobs appear as
1596-454: A separate annex was built to house them all. Another structure was built for the display of photography . Memorial Hall was designed by Herman J. Schwarzmann, who basically adopted an art museum plan submitted by Nicholas Félix Escalier to the Prix de Rome competition in 1867–69. Memorial Hall became the prototype, both from a stylistic and organizational standpoint, for other museums such as
1680-461: A sliding bolt that can also function as a handle. From at least the Middle Ages blacksmiths made drop latches which could be opened by a handle connected to the latch by a split pin passing through the door. Taking the form of a ring or strip, these handles could be elaborate and decorated but were universally made of metal. It can be speculated that since the task of making door hardware fell to
1764-665: Is now the University of the Arts . Used for a time as a police station, the building now houses the Please Touch Museum , which includes a faithful 20x30-foot model of the exposition grounds and 200 buildings. The Women's Pavilion was the first structure at an international exposition to highlight the work of women, with exhibits created and operated by women. Female organizers drew upon deep-rooted traditions of separatism and sorority in planning, fundraising, and managing

#17327767672191848-1053: The Art Institute of Chicago (1892–1893), the Milwaukee Public Museum (1893–1897), the Brooklyn Museum (1893–1924), and the Detroit Institute of Art (1920–1927). Libraries such as the Library of Congress , the New York Public Library , and the Free Library of Philadelphia also emulated its form. Finally, Memorial Hall was the architectural inspiration for the German capitol, the Reichstag building in Berlin. After

Nearly 10 million visitors attended the exposition, and 37 countries participated in it. The Great Central Fair on Logan Square in Philadelphia , in 1864, also known as the Great Sanitary Fair, was one of

The central domed area is surrounded by four pavilions on the corners, with open arcades to the east and west of the main entrance. It provided 75,000 sq ft (7,000 m ) of wall surface for paintings and 20,000 sq ft (1,900 m ) of floor space for sculptures. The exposition received so many art contributions that
2100-624: The 4th century CE was producing a range of automated doors, door locks and door bars. There is little record of door handle development between the Fall of Rome and about 1000 CE. The oldest European doors include the Bernward Doors and the Westminster Abbey door. The Bernward doors have large decorative ring-shaped handles of a type that became common on decorated doors from that period onwards. The Westminster Abbey door features
2184-578: The Centennial Exposition. Both had a similar neo-Gothic appearance, including the waving flags, a huge central hall, the "curiosities" and relics, handmade and industrial exhibits, and also a visit from the U.S. president and his family. The idea of the Centennial Exposition is credited to John L. Campbell, a professor of mathematics, natural philosophy , and astronomy at Wabash College in Crawfordsville, Indiana . In December 1866, Campbell suggested to Philadelphia Mayor Morton McMichael that

Philadelphia streetcars increased service, and the Pennsylvania Railroad ran special trains from Philadelphia's Market Street , New York City , Baltimore , and Pittsburgh . The Philadelphia and Reading Railroad ran special trains from the Center City part of Philadelphia. A small hospital was built on the exposition's grounds by the Centennial's Medical Bureau, but despite

The Centennial National Bank was chartered on January 19, 1876, to be the "financial agent of the board at the Centennial Exhibition, receiving and accounting for daily receipts, changing foreign moneys into current funds, etc.," according to an article three days later in The Philadelphia Inquirer . Its main branch, designed by Frank Furness ,
2436-583: The Exposition, the building continued to be used for horticultural exhibits until it was severely damaged by Hurricane Hazel in 1954 and was subsequently demolished. As a replacement, the Fairmount Park Horticulture Center was built on the site in 1976 as part of the United States Bicentennial exposition. Designed by Joseph M. Wilson and Henry Pettit, Machinery Hall was the second largest structure in

The United States government had a cross-shaped building that held exhibits from various government departments. The remaining structures were corporate exhibitions, administration buildings, restaurants, and other buildings designed for public comfort. The formal name of

2688-480: The Neolithic period. Locking or latching mechanisms have existed from about the same time. Key operated door locks have existed at least since Egyptian civilisation. The keys of these locks, which could be as large as two feet long, also functioned as door handles to slide a locking bolt and open the door. Subsequently Roman domuses and insulae incorporated lockable doors of a different design but also opened by

Naysayers argued that the project would not be able to find funding, other nations might not attend, and domestic exhibits might compare poorly to foreign ones. The Franklin Institute became an early supporter of the exposition and asked the Philadelphia City Council for use of Fairmount Park . With reference to
2856-539: The United States. On June 1, 1872, Congress created a Centennial Board of Finance to help raise money. The board's president was John Welsh , brother of philanthropist William Welsh, who had raised funds for the Great Sanitary Fair in 1864. The board was authorized to sell up to $ 10 million in stock via $ 10 shares. The board sold $ 1,784,320 ($ 45,381,205 in 2023 ) worth of shares by February 22, 1873. Philadelphia contributed $ 1.5 million and Pennsylvania gave $ 1 million. On February 11, 1876, Congress appropriated $ 1.5 million in
2940-631: The Women's Pavilion was commissioned in 1873 by the United States Centennial Board of Finance with the expectation that it would generate enthusiasm for the celebration of the fair and increase subscriptions to exposition stock. Elizabeth Duane Gillespie, president of the Women's Centennial Committee, led the effort to gather 82,000 signatures in two days to raise money for the pavilion. Gillespie also helped convince Congress to grant additional funding. It took only four months to raise
3024-679: The arm or foot. The Antique Doorknob Collectors of America (ADCA) is a nonprofit organization dedicated to the collection of antique doorknobs. Established in 1981, they have over 1000 members as of 2018. The doorknob collecting hobby was kick-started after the publication of The Antique Doorknob by Maud Eastwood in 1976. Handle A handle is a part of, or attachment to, an object that allows it to be grasped and manipulated by hand . The design of each type of handle involves substantial ergonomic issues, even where these are dealt with intuitively or by following tradition. Handles for tools are an important part of their function, enabling
3108-402: The auction held on December 1, 1876, it was bought for $ 250,000. It quickly ran into financial difficulties but remained open through 1879 and was finally demolished in 1881. The third-largest structure at the exposition was Agricultural Hall. Designed by James H. Windrim , Agricultural Hall was 820 ft (250 m) long and 540 ft (160 m) wide. Made of wood and glass, the building
3192-420: The blacksmith, the use of turned or carved wooden knobs was not convenient. Wooden latches are also known from this period. A finger hole could be made that allowed the user to raise the latch from the other side of the door. The finger hole would double as a grip or handle. In another common design, transferred motion to open the latch was effected by a string passing through the door, which could be withdrawn from
3276-481: The building was east–west in direction, making it well lit, and glass was used between the frames to let in light. Skylights were set over the central aisles of the structure. The corridors of the building were separated by fountains that were attractive and also provided cooling. The structure of the building featured a central avenue with a series of parallel sheds that were 120 ft (37 m) wide, 1,832 ft (558 m) long, and 75 ft (23 m) high. It
3360-423: The building's corners. These towers had small balconies at different heights that served as observation galleries. Within the building, exhibits were arranged in a grid, in a dual arrangement of type and national origin. Exhibits from the United States were placed in the center of the building, and foreign exhibits were arranged around the center, based on the nation's distance from the United States. Exhibits inside

3528-482: The cost of lock and latch manufacture with lock designers including Barronin , Chubb and Bramah competing against each other around the end of the 18th century. From the 18th century, a wide variety of lever handles and knobs started to be produced, with designs determined by local aesthetic preference and technology. Knobs could be cast, turned, brazed or spun from a variety of materials. Levers could be wrought or cast. Designs became more complicated and might include
3612-403: The design by Hermann J. Schwarzmann. Their overarching goal was to advance women's social, economic, and legal standing, abolish restrictions discriminating against their gender, encourage sexual harmony, and gain influence, leverage, and freedom for all women in and outside of the home by increasing women's confidence and ability to choose. A project of the Women's Centennial Executive Committee,
3696-516: The door to which the handles are attached. Some handles are attached on both sides by screwing or sliding them directly onto the spindle, and then securing one or more retaining screws (set screws) through the knob perpendicular to the flat of the spindle. Handles that lose traction can frequently be repaired by replacing or adjusting the set screw, which prevents them from slipping on the spindle. Other types of handles, typically used in Europe, slide onto
3780-502: The door, depending on local culture, decorative style, or owner preference. The distance from the edge of the door to the center of the handle is called the backset. The location of the door handle along the vertical axis on the door may vary between 34 and 48 inches (860 and 1,220 mm). Doorknobs can be difficult for the young and elderly to operate. For this reason, door handles in most American commercial and industrial buildings and in many households are lever-operated, rather than
3864-505: The evolved bicycle, with tension spokes and a large front wheel. Two English manufacturers, Bayless Thomas and Rudge, displayed their high-wheel bikes (called "ordinary bikes" or "penny farthings") at the exposition. The bicycle displays inspired Albert Augustus Pope to begin making high-wheel bikes in the United States. He started the Columbia Bike Company and published a journal called " LAW Bulletin and Good Roads", which

With a superstructure made of wood and glass resting on a foundation of massive masonry, it had a main hall painted light blue, 1,402 ft (427 m) long and 360 ft (110 m) wide, with a wing of 208 ft (63 m) by 210 ft (64 m) attached on the south side of the building. The length of the building was 18 times its height. With eight entrances, it occupied 558,440 sq ft (51,881 m ), had 1,900 exhibitors, and took six months to construct. The exhibits focused on machines and evolving industries. Machinery Hall
4032-419: The exposition introduced the general public to the notion of landscape design, as exemplified the building itself and the grounds surrounding it. A long, sunken parterre leading to Horticultural Hall became the exposition's iconic floral feature, reproduced on countless postcards and other memorabilia. This sunken garden enabled visitors on the raised walkways to see the patterns and shapes of the flowerbeds. After
4116-607: The exposition mainly consisted of two types of building, traditional masonry monuments and buildings with a structural framework of iron and steel. The Centennial Commission turned to third-place winner's architect Henry Pettit and engineer Joseph M. Wilson for design and construction of the Main Exhibition Building. A temporary structure, the Main Building was the largest building in the world by area, enclosing 21.5 acres (87,000 m ). It measured 464 ft (141 m) in width and 1,880 ft (570 m) in length. It

The average temperature was 81 °F (27 °C), and on ten days during the heat wave the temperature reached 100 °F (38 °C). The average daily attendance for July was 35,000, but it rose in August to 42,000 despite
4284-411: The exposition was the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, but the official theme was the celebration of the United States centennial. This was reinforced by promotional tie-ins, such as the publication of Kate Harrington 's Centennial, and Other Poems , which celebrated the exposition and the centennial. At the same time, the exposition was designed to show

In 1928 the museum moved to Fairmount at the head of the Benjamin Franklin Parkway, and in 1938 was renamed the Philadelphia Museum of Art . Memorial Hall continued to house the school, and afterward was taken over by the Fairmount Park Commission in 1958. The museum school
4452-477: The exposition, which was dedicated on July 4, 1873, by Secretary of the Navy George M. Robeson . The Commission decided to classify the exhibits into seven departments: agriculture, art, education and science, horticulture, machinery, manufactures, and mining and metallurgy. Newspaper publisher John W. Forney agreed to head and pay for a Philadelphia commission sent to Europe to invite nations to exhibit at
4536-437: The exposition. Despite fears of a European boycott and high American tariffs making foreign goods not worthwhile, no European country declined the invitation. To accommodate out-of-town visitors, temporary hotels were constructed near the exposition's grounds. A Centennial Lodging-House Agency made a list of rooms in hotels, boarding houses , and private homes and then sold tickets for the available rooms in cities promoting
4620-418: The exposition. In 1869, Schwarzmann began working for the Fairmount Park Commission, which administered the site of the 1876 Centennial Exposition. It is one of the great urban parks of the United States; its importance in landscape history was surpassed only by Central Park . Schwarzmann was the chief architect for the Centennial Exposition, designing Memorial Hall, Horticultural Hall, other small buildings, and

Drawing lessons from this failure, the Philadelphia exposition was ready for its visitors, with direct railroad connections to service passenger trains every 30 minutes, trolley lines, street cars, carriage routes, and even docking facilities on the river. More than 200 buildings were constructed within the exposition's grounds, which were surrounded by

On exhibit were over 80 patented inventions, including a reliance stove, a hand attachment for sewing machines, a dishwasher, a fountain griddle-greaser, a heating iron with removable handle , a frame for stretching and drying lace curtains, and a stocking and glove darner. The Centennial women not only showed domestic production but also employed
4872-469: The hand-focused motions described: Another category of hand-operated device requires grasping (but not pulling) and rotating the hand and either the lower arm or the whole arm, about their axis. When the grip required is a fist grip, as with a door handle that has an arm rather than a knob to twist, the term "handle" unambiguously applies. Another clear case is a rarer device seen on mechanically complicated doors like those of airliners, where (instead of

From about mid-17th century, drop handles were increasingly replaced by forged vertical handles formed as a bracket fixed to the door at the top and bottom of the bracket. Vertical handles with an incorporated latch mechanism, known as Suffolk latches were developed. By

His work for the Centennial Exposition was informed by the Vienna International Exposition in 1873 , which Schwarzmann visited to study the buildings and the grounds layout. The Vienna International Exposition in 1873 was marred by disastrous logistic planning and was taken as a cautionary example. At the Vienna Exposition, there was no convenient way for visitors to reach

Door handles have been in existence for at least 5000 years, and its design has evolved since, with more advanced mechanism, types, and designs made. Some door handles are also arm- or foot-operated to reduce transmission of contagious illnesses. Door handles have been in existence at least since

The fairs provided a creative and communal means for ordinary citizens to promote the welfare of Union Army soldiers and dedicate themselves to the survival of the nation, and the Great Central Fair bolstered Philadelphia's role as a vital center in the Union war effort. It anticipated the combination of public, private, and commercial investments that were necessary to mount
5376-512: The mid-18th century, forged vertical handles were being replaced by cast vertical handles, including the Norfolk latch . The early 17th century also saw metalworking of a standard that allowed mortise locks and latches and compact rim locks and latches to be made for use in the most expensive buildings. These locks used a twisting motion to operate, accelerating development in decorative doorknobs. The Industrial Revolution dramatically reduced

The three nearly universal requirements of are: Other requirements may apply to specific handles: One major category of handles are pull handles, where one or more hands grip the handle or handles, and exert force to shorten the distance between the hands and their corresponding shoulders. The three criteria stated above are universal for pull handles. Many pull handles are for lifting, mostly on objects to be carried. Horizontal pull handles are widespread, including drawer pulls , handles on latchless doors and
