ABSTRACT:
An energy saving arrangement in which motors performing mechanical work in automatic pin spotters are disconnected from power lines when a bowling play is discontinued after a predetermined time interval. A time delay relay is repeatedly actuated by a circuit connected to the rake latching bar. The time delay relay maintains a control relay energized provided that the rake latching bar actuates the circuit to the time delay relay within a predetermined time interval. If no such actuation takes place, then the control relay is released and the power motor for the pin spotter is switched off. The motor controlling the speed of the ball toward the bowler is similarly switched off after a predetermined time delay from the instant that the ball actuates a switch on its way back to the bowler or after a predetermined time delay after the rake latching bar is released. A capacitor bank is provided, furthermore, to correct the power factor of the energy applied to the motor and thereby results in energy savings.
