Abstract

An improved pusher-type chain for a conveyor of the type comprising an elongated base means having a bottom and upstanding side guides or flanges. The base means may be made up of two or more sections joined together end-to-end in such manner as to permit them to be shifted with respect to each other from side-to-side horizontally and vertically upwardly and downwardly about the juncture. The pusher-type chain is a continuous chain adapted to be driven so that one of its spans moves longitudinally along the upper surface of the base means bottom and between the side guides or flanges in a conveying direction so as to advance therealong the material being conveyed. The chain comprises a plurality of pusher elements normally extending substantially transversely of the conveying direction. Adjacent pusher elements are joined together by a series of block-like links and pairs of plate-like links arranged alternately and joined together and to the pusher elements by pintle means permitting vertical articulation. The plate-like links of selected pairs are provided with reliefs on their inside surfaces and the end of each block-like link adjacent such a relief is provided with a pintle hole elongated transversely of its axis, permitting horizontal articulation of the chain between its pusher elements.
