ABSTRACT:
A device for individually transferring workpieces comprises a loading chute for successively feeding by gravity individual workpieces to a standby position on a support member, and a pusher reciprocates through a forward stroke to push a workpiece from the standby position along the support member toward a working position while blocking the loading chute so as to prevent the next workpiece from dropping from the loading chute into the standby position and through a return stroke to unblock the loading chute to permit the next workpiece to drop from the loading chute into the standby position. A fluid delivery passage formed in the loading chute delivers pressurized fluid lubricant in a first fluid stream directed toward the standby position to assist in maintaining the workpiece in the standby position and delivers pressurized fluid lubricant in a second fluid stream directed toward the working position to assist the pusher in transferring the workpiece from the support member to the working position.
