Title: Improvements in or relating to automatic adjusting devices for brakes
IPC: F16D65/56
Filed: 1936-10-17
Abstract: 483,159. Brake adjusting devices. AUTOMOTIVE PRODUCTS CO., Ltd., and CLENCH, E. C. S. Oct. 17, 1936, No. 28317. [Class 103 (i)] In an automatic shoe-adjusting device of the kind in which excess reciprocatory movement of a shoe actuating member effects an increase of length in a screw-and-nut device disposed between the actuating member and the shoe, the device is actuated by a oneway friction clutch and a pin engaging an oblique slot, the normal shoe clearance being determined by play between the pin and the slot. The shaft 19 of the shoe expanding cam 16 of an internal expanding brake is mounted in a housing 13 secured to the back plate 10. Between the cam and the shoe ends 17, 18 are plungers comprising each a collar 23, 23a on a screwed stem 26, 26a. The heads 27, 27a of the stems have hardened plates 28, 28a for engagement with the cam 16. The stem 26 is integral with one member 33 of a one-way clutch comprising balls 36 that wedge between this member and a cylindrical member 37 when the member 37 is turned in one direction. A fixed pin 39 engages a slot 38 in the member 37, the slot being inclined to the axis of the plunger and the diameter of the pin being less than the width of the slot. If when the shoes are expanded the axial movement of the plunger with the member 37 is greater than the play between the slot and pin the member 37 is turned idly and during the return movement turns the stem and thus advances the collar 23 which is held from rotation by a pin-and-slot 24. Simultaneous turning of the screws 26, 26a to adjust both shoes may be effected by a spindle 31 which passes through a flared aperture in the cam 16 and has flattened ends 30, 30a received in slots in the heads 27, 27a. The pitch of the screws 26, 26a may be different to correspond to the rates of lining wear of the two shoes. A modification is shown in which the plungers of a hydraulic shoe expanding cylinder have a similar adjusting device. The obliquity of the slot relatively to the screw pitch may be such that only a small part of the excess shoe clearance is taken up at eacl brake application so as to prevent the adjust ment from being upset by temporary drum expansion.
