ABSTRACT OF THE DISCLOSURE A ring dispenser comprising a rotating rod having an acme thread along one portion thereof and a helical coil spring at a dispensing end thereof feeds individual rings to a ring transfer device located at the dispensing end of the rod. The rod is rotated by a motor and the rings are automatically separated and directed to the end of the rod where a sensor detects the presence of the ring and stops the motor. When the ring transfer device is ready to pick up a ring, the motor starts again and a ring slides off a conical tip of the rod onto the transfer device by rotation of the rod. The rings have diameters greater than the separation between the individual threads of the rod so that the rings move on the crests of the threads and are out of engagement with the thread roots. The spacings between the convolutions of the coil spring are greater than the thickness of the rings so that the rings move on the rod surface as the rings approach the dispensing end of the rod.
