Pneumatic tool attached using a coupling. A coupled pair consists of a male nipple or plug and a female coupler or socket. One side is connected to a flexible supply hose; the other may be attached to a manifold, valve, tool, or another hose. A female coupler is used on the supply side, and a male nipple is used on the receiving side.
The diagram from Beard's 1897 coupler patent [7]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [8] [9] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [7] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
Like all Janney couplers, the Tightlock is "semi-automatic". The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that ...
IEC 60309 (formerly IEC 309 and CEE 17, also published by CENELEC as EN 60309) is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes".
Type F interlocking couplers on upcoming PNR narrow-gauge flatcars. [37] Type H tightlock coupling on most PNR rolling stock starting with the 900 class. Link and pin couplers on the Hawaiian Philippine Company of Negros Island. [38] Older Manila Railroad stock also use link and pin alongside English couplers. Scharfenberg couplers on the MRT ...
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
SA3 couplers Click here for animation of coupling SA3 details End view of SA3 coupler, with release lever to the left.. SA3 couplers (also known as СА3 or СА-3 couplers per the typical foundry stamp on top of these couplers, meaning "Советская Автосцепка, 3" in Russian or "Soviet Auto-latch 3" in English) or Willison coupler and Russian coupler are railway couplings used ...
Inter-stock coupling was with the automatic coupler (with the buffers retracted), while connection to the locomotive was with the buffer-and-chain system with a screw coupler. Today this dual coupling system has been adopted for all loco-hauled passenger trains in Great Britain to allow faster shunting operations.
