DEFINITION

Classification: 335/65

(under subclass 64) Subject matter wherein the mechanical delay means comprises separate and independent motor means. The motor may be either electric or spring driven.

(1) Note. Delay devices which are operated by an induction vane driven by the contact actuating magnet, or other magnet means forming a component of the switch, are classified in subclass 63 above.

SEE OR SEARCH THIS CLASS, SUBCLASS:

30, for automatic circuit interrupters with trip reclosing or resetting means utilizing mechanical motor delay control.

68+, below, for switches wherein the actuation of the main contacts is under the control of an electric motor.

SEE OR SEARCH CLASS 185, Motors: Spring, Weight, or Animal Powered, appropriate subclasses for mechanical motors, per se, of the weight or spring actuated type.

200, Electricity: Circuit Makers and Breakers,

35+, for switches of the retarded type with motor driven clock train means.

318, Electricity: Motive Power Systems, and

486, for automatic stopping or starting switches with pilot or servo-motor time delay means.

388, Electricity: Motor Control Systems, art collection 921 for motor control systems including time delay means.
