Abstract
An operating control circuit for an amusement device of the simulated driving type, wherein the speed of the simulated vehicle is regulated by an operator-controlled accelerator and a gear shift, each electrically arranged to cooperate and interrelate so as to respond to the manual skills and ability of the operator.
Claims4
A speed control system for use in an amusement device of the simulated driving type, including
- a. an electric motor,
- b. a circuit for energizing the motor,
- c. a plurality of resistors connected in series in said circuit for the motor, normally restricting an operating current to the motor,
- d. a plurality of relay switches connected in parallel, with certain of said relay switches in open shunt circuits with respect to certain of said resistors,
- e. a plurality of relays for activating said relay switches in the circuit for energizing the motor,
- f. means for selectively energizing said relays so as to close their respective said relay switches to shunt one or more of said resistors so as to increase the energizing current to the motor, and
- g. manually operated means for controlling the energization of certain of said relays by said means for selectively energizing said relays to render said relay switches of said certain relays ineffective to close a shunt circuit with respect to certain of said resistors.
