Abstract

412,473. Adjusting brake shoes. WOOLER, J., Willow Bungalow, West End Lane, Ruislip, Middlesex, and MURPHY, W. J. BALFOUR-, 42, Langley Park Road, Sutton, Surrey. Oct. 30, 1933, No. 30077. [Class 103 (i).] The common pivot of a pair of brake shoes acting on a drum comprises a split bushing which is expanded to take up wear of the shoes by axially-movable wedge members actuated by ratchet mechanism from the usual cam lever. The pair of shoes B are pivoted upon a split bush 15 having tapered recesses and mounted upon a pair of correspondingly tapered heads 2b, 4<a> formed respectively upon a tubular member 2 and a spindle 4 passing through it. The member 2 is slidably but non-rotatably carried by the anchor plate E of the brake. A nut-member 5 is threaded on the oppositely-threaded parts of the members 2, 4 and has a ratchet-toothed face 5<a> coacting with a spring-pressed ratchet disc 9 provided with a lever 11 which is connected by link 16 to the lever D of the usual operating cam of the brake. The parts are enclosed in a casing 13 through which the end of the spindle 4 passes. A spring-pressed plunger 8 engages recesses in the nut 5 to prevent undesired rotation thereof. If in applying the brake the levers D, 11 move in excess of the normal, the ratchet teeth engage so that the nut 5 is turned and the heads 2<b>, 4a are moved towards each other to expand the bush 15, this action being repeated in the next application of the brake.
