Abstract

503,229. Brush holders for dynamoelectric machines. SPENCER, T. D., and PATENT LIGHTING CO., Ltd. Oct. 4, 1937, No. 26857. [Class 35] A brush holder consists of a metal tube fixed in an insulating bushing provided with two opposite slots accommodating a conducting U-shaped spring clip bearing against the tube. In the form shown, the tube 27 is forced into an insulating bushing 28 secured by screws 29 in a hole 30 in the bearing bracket 21 and the brush-holder lead terminates in a clip 32 for pressing against the sides of the tube 27 where they are exposed by the slots 31 in the bushing 28.
