Abstract
A center link pusher dog assembly for power and free conveyors includes a pusher dog member with a mounting base and a pusher dog projection upstanding therefrom. The mounting base has depending lugs and a rear shoulder to engage an abutment formed by a reduced central area of a center link of a conveyor chain. A bore through the pusher dog member recevies a bolt for clamping a center link between the pusher dog member and a conventional chain support type of power trolley. The lugs engage upstanding teeth on a mounting end of the power trolley and side walls of the center link to fix the longitudinal position of the pusher dog member relative to the power trolley and the center link and to fix its lateral position relative to the center link.
