Abstract

440,030. Brush-holders for dynamoelectric machines. BAKER, W. S. GRAFF-, 30, Leonard Court, Kensington High Street, London, and LONDON PASSENGER TRANSPORT BOARD, 55, Broadway, Westminster. June 14, 1934, No. 17621. [Class 35] A brush-holder consists of a lidded box of insulating- material containing the spring and a pigtail for connecting the brush to a terminal for connection to the external circuit. In the form shown, three concentric springs located in a cup 20<a> press the brush 3 against the commutator and the brush is connected by pigtail 9 to terminal 10 carried on the insulating box 6 which has a lid 7 secured by a toggle clip 16. The box is radially adjustable on a splined support 31 which is movable axially by means of a bolt and slot connection. The box may accommodate several brushes arranged in a row parallel to the commutator axis.
