Abstract

1,119,614. Brushes for dynamo-electric machines. SOC. LE CARBONE-LORRAINE. 20 April, 1966 [23 April, 1965], No. 17369/66. Heading H2A. To prevent corrosion by a coiled metal strip pressure spring 5, a metallic plate 3 fixed to the upper part of one brush 1 of a twin brush assembly for a commutating electrical machine and which bears on the pressure-conveying surfaces of both brushes 1, 2 is provided on its surface which receives the pressure with an insulating relatively low coefficient of friction coating 4. Such coating may be P.T.F.E., nylon, or an epoxy resin obtained by deposition or fixing a plate thereof.
