Abstract

815,426. Electric motor brakes. CLEVELAND ELECTRIC MOTOR CO. Sept. 20, 1957, No. 29705/57. Class 103 (1). [Also in Group XXXV] A brake for an electric motor or other dynamo-electric machine, comprises a disc 12 which, when the motor is stationary is normally pressed into engagement with the friction lining secured to flange 9 by radially directed coil springs 48, such springs 48 acting through wedge elements 42 to press the disc 12 to the right against the force of spring 14. When the motor is energized and shaft 4 rotates, the centrifugal effect on elements 42 overcomes the force of springs 48 and the spring 14 moves the disc 12 out of contact with the member 11 to the condition shown in Fig. 2.
