ABSTRACT:
A device for supplying helical wire compression springs in sequence to an output conduit includes a casing defining a spring supply chamber therein for receiving a plurality of helical wire compression springs of a first diameter. A delivery tube is mounted on top of the casing and defines a spring outlet opening of a diameter slightly larger than the first diameter. The delivery tube communicates, through the spring outlet opening, between the chamber and the output conduit. An agitator, including an air inlet communicating with the bottom of the chamber, supplies air under pressure to the chamber such that springs in the chamber are agitated, and pass out of the chamber through the delivery tube and into the output conduit. A shedder piston surrounds the spring outlet opening of the delivery tube, and moves with respect thereto so as to dislodge springs entangled within or blocking the spring outlet opening.
