Abstract

969,839. Brush-gear for dynamo-electric machines. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 22, 1963 [March 26, 1962], No. 11447/63. Heading H2A. A brush-holder consists of an insulating holder 1 providing a supporting surface 5 for the trailing side of the brush 4, and a pressure lever 12 loaded by a spring 8 and having its operative end curved to radius R and acting on the brush adjacent its supported side to prevent tilting. The pressure-arm interlocks pivotally at C with an upstanding tongue 7 on a conducting plate 6 which also serves as an abutment for the other end of the spring. Brush-wear is limited by a stop 16. The relationship between the spring and the arm is such that the loading on the brush is substantially constant.
