Abstract

576,613. Brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. (Bendix-Westinghouse Automotive Air Brake Co.). Nov. 16, 1944, No. 22680. [Class 103 (i)] In a brake-mechanism slack adjuster of the worm and worm-wheel type, the worm is held against inadvertant rotation by an axially slidable member 21 having a squared hole 24 to engage a square extension 17 of the worm shaft, and the edge 23 of the member 21 is splined to engage corresponding splines 20 on the stationary worm-retaining nut 13. When it is necessary to adjust the brake, the member 21 is pulled, against the action of a spring 28, away from the worm to disengage the splines, and is then rotated by a wrench engaging flats 29. The surfaces 31, 32 are chamfered, so that the act of placing the wrench in position, moves the member 21 to disengage the splines. The spring 28 is housed between a shoulder on the member 21 and a collar 18 secured to the end of the worm shaft by a screw 19. The worm wheel 7 is retained in position by side plates 33 having peripheral threads for screwing into the wormcasing. The side plates have central openings 34 forming bearings for hubs on the worm.
