Abstract:
1. A combination of an apparatus in a conveyor for preventing wear of a support member and a conveying chain movable in a predetermined direction thereover, said converyor comprising: a support member; and a wear strip including an elongate body of a molded plastics material including a conveying chain contacting side and an opposite mounting side to be mounted on a surface of the support member, the mounting side of the body including at least one integrally molded plastics material mounting tab extending outwardly therefrom for mounting the body on the support member so as to extend longitudinally in the predetermined direction, the mounting tab including at least one complementary projection spaced from the body, the projection having a free end spaced from the mounting tab in the longitudinal direction and being resiliently displaceable toward the mounting tab, the mounting tab and the projection when in a free state having a predetermined overall extent in the longitudinal direction, and the free end of the projection defining a locking detent including a notch facing longitudinally away from the mounting tab and disposed such that the mounting tab can be inserted through a hole in the support member having an extent in the longitudinal direction smaller than the predetermined overall extent of the mounting tab and the projection to cooperatively engage the notch of the locking detent with an edge of the support member bounding the hole for holding the mounting tab in the hole while the projection is resiliently displaceable for allowing limited resilient longitudinal movement of the body relative to the support member in response to thermal stress.
