Abstract

901,656. Brushes for dynamo-electric machines. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 9, 1959 [Oct. 14, 1958], No. 34294/59. Class 35. To allow for greater wear at the trailing edge 4 than the leading edge 5, a brush for use with disc or drum type commutators is made of trapezoidal shape. The trailing side may be curved or straight, as shown. The bush-holder consists of an aperture in a conducting plate.
