ABSTRACT:
An automatic feeder apparatus is disclosed for feeding collar stays and the like to an associated machine including a first fluid cylinder having a reciprocating piston rod and a second fluid cylinder carried by the piston rod of the first fluid cylinder. The second fluid cylinder includes a reciprocating piston rod on which a suction device is carried which includes a pair of suction tubes having a suction end and a discharge end with air being introduced intermediate the ends to create the suction at the suction ends. A master solenoid valve controls delivery of a pressurized fluid to the fluid cylinders and cooperates with a systematic arrangement of in-line valves which are actuated by the movement of the suction device to provide an automatic sequence for pick-up and delivery of a collar stay.
