摘要

A device for feeding eyelets and the like of diverse sizes to a riveting machine. The device has to elongated guide members disposed with respective straight side edges defining a longitudinal slot. The slot is disposed to receive eyelets at one end for passage along the length thereof to the other end. A support hinged on the riveting machine holds the device with the slot disposed for delivery of eyelets to a proper joint. Jigs received in slots oblique and symmetrical to the axis of the longitudinal slot join the guide members and are displaceable axially thereof to vary the width of the longitudinal slot. These jigs are actuated by spacers axially spaced on a rod having oppositely threaded portions that space the spacers axially as the rod is rotated. The spacers bear on the jigs and displace them relatively axially so that they move in the oblique slots and the width of the longitudinal slot is adjusted with a constant width along its length. The jigs are releasably locked in the adjusted positions thereof.
