Abstract
A circuit responds to a level-sensing device, adjacent a coin-holding tube, to cause an electric motor to rotate a coin-receiving drum until sufficient coins issue from that coin-receiving drum to fill that coin-holding tube. Ordinarily, coins will issue from that coin-receiving drum in such rapid succession that the motor need not be energized very long. However if, because some coins within that coin-receiving drum interact to form a 'bridge' which retards or prevents the issuance of other coins from that coin-receiving drum, or if for any other reason coins do not issue from that coin-receiving drum, the circuit will keep that motor energized for a finite length of time, will de-energize that motor, and will energize that motor for a second finite length of time. Usually, the de-energization of the motor and the succeeding energization of that motor for a finite length of time will permit the coins within the coin-receiving drum to shift sufficiently to enable coins to issue from that coin-receiving drum during that succeeding energization of that motor for a finite length of time; and, in such event, the motor will continue to rotate the coin-receiving drum until sufficient coins issue from that coin-receiving drum to fill the coin-holding tube.
