Abstract
A chain for a conveyor comprising an elongated base means (8, 9) having a bottom and upstanding side guides or flanges (11, 12) is provided. The 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 (10) and between side guides or flanges in a conveying direction so as to advance the material being conveyed. The chain comprises a plurality of Y-shaped connector links (20) and a plurality of flight arms connecting links (34) having arms attached thereto and normally extending substantially transversely of the conveying direction. Adjacent elements (41) are joined together by a series of bearing and retaining pins (30, 31) so as to permit vertical and horizontal articulation. The flight arms are attached to the flight arm connecting links (34) independently of the main bearing pins (30) that hold the various links of the chain together.
