take away conveyor 22 in its associated lane and the pushers will have ceased to have an effect on the object as the various pushers pass downstream beyond the downstream end of the conveyor 16 with particular reference now to fig1 the pushers will be retracted slightly as indicated generally by the return angle for the cam track structure indicated generally at 80e in fig1 and the pushers will pass around the downstream sprockets of the side push conveyor the pushers are returned to their initial positions best shown at the upstream end of the side push conveyor in order to be received in the cam tracks defined for them in the superstructure as indicated generally at 80 80d by a fixed camming or plow means shown in broken lines in fig1 at 81 and located below the lower return run of the side push conveyor this elongated plow 81 is adapted to fully retract all of the pushers including the guide pushers in order that their associated cam follower rolls are received in the proper cam tracks provided for them in the superstructure just described still with reference to the cam track defining superstructure it should be noted that means is provided for yieldably mounting said superstructure to the fixed support structure associated with the side push conveyor preferably said means comprises a pair of blocks 92 92 one of which.
