Abstract

354,268. Brakes. LAVAUD, D. S. DE, 179, Rue de la Pompe, Paris. Jan. 28, 1930, No. 2927. Convention date, Jan. 30, 1929. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] A device for automatically adjusting the distance between two parts of a transmission system when the stroke of the system exceeds a predetermined value, applicable particularly for compensating for wear in brake mechanism comprises a cam, eccentric or a screw and nut co-operating with a ratchet and pawl whereby the cam &c. is rotated on the return stroke if the initial stroke exceeds the predetermined value. The brake shown in Fig. 1 comprises brake shoes 1, 2 adapted to be applied to a drum 3 by pistons 10, 11 actuated by pressure fluid admitted to chambers 5, 6 and acting upon rubber caps 8, 9. The pressure is transmitted to the shoes through cams 12, 13 pivoted on the pistons and provided with ratchets 16, 17 engaged by pawls 18, 19. If when the brake is applied the stroke of the pistons exceeds a certain value, the ratchet teeth slip over the pawls and on the return movement the cams are rotated theieby. In Fig. 2, a nut 12 rotatable on the pull-rod 11 screws on a member 2 secured to the pull-rod 11<1>. The nut 12 has ratchet teeth 17 engaged by a pawl 18 carried by a sleeve 20 provided with a quick-pitch screw thread engaging a corresponding fixed nut member 22. During the operative stroke of the pull-rod 11, 11<1>, the sleeve 20 and the pawl are rotated and if the stroke is sufficient, the pawl slips a tooth of the ratchet so that on the return movement the ratchet and nut 12 are turned.
