805,449. Endless chain conveyers. FISHER & LUDLOW Ltd. June 24, 1957 [March 29, 1956], No. 9806/56. Class 78 (1). [Also in Group XXV] In an endless chain conveyer wherein the or each chain is made up of sets of drop-forged links, each set consisting of a hollow elongated body 13, a pair of link plates 15 and a connecting pin 18 adapted to be passed through apertures in the body and link plates, the pins 18 are extended on one or both sides of the chain and carry supporting rollers 23. As applied to a slat conveyer the slats 28 are secured between a pair of such chains by pairs of clamps 30 which are clamped on inwardly facing extensions of the pins 18, the clamps being secured to the slats by bolts 31. The rollers 23 are carried on outwardly facing extensions of the pins 18 and are located against axial movement by a locating member such as a circlip. The pins are also provided with laterally projecting wings 20 which engage in grooves 19 in the link plates 15 to lock the pins against rotation relative to these plates. Both the body 13 and the link plates 15 are slotted. To assemble the chain the body 13 and link plates 15 are overlapped so that the connecting pin 18 and its wings 20 can be passed through them. The plates 15 and body 13 are then turned at rightangles to each other so that the plates 15 can be pressed against the reduced central portion of the body 13 to allow engagement of wings 20 with the grooves 19, after which the links are again straightened-out to lock the parts in position.
