Abstract

412,339. Brush-holders for dynamoelectric machines. ORR, W., 327, Southey Green Road, Sheffield, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 14, 1933, No. 4560. [Class 35.] In a brush-holder wherein a flat spiral spring presses on the top of the brush, a link which is pivoted substantially concentric with the spindle of the spring is provided and is attached to the spring adjacent the tip thereof. As shown, the limbs of the U -shaped link 15 which is pivoted on the spindle 8 extend on both sides of the spring 7 and are connected thereto by a pin 16 carried in a bush 17 on the spring. Pressure is exerted on the second brush 2 by a pair of narrower springs 5 arranged on the outer sides of the link 15 and connected together by a member 12. The invention is also applicable to holders for single brushes.
