(under subclass 4) Composite weight motors which include escapements for controlling the operation of the motor.
(1) Note. By the term "escapement", as used throughout this class, is meant a device which receives energy from a power plant and by virtue thereof performs a cycle of movements in which the escapement first causes the power element to cease its motion and later permits it to resume its motion. Throughout this class, if the escapement includes a spring or a weight which derives its energy from another motor, the device is classified in the appropriate Winding Motor subclass instead of in the Escapement controlled subclass and a cross-reference is placed in the appropriate Winding, Overwinding preventers subclass.
