Title: Disc Brake
IPC: F16D65/54
Filed: 1967-08-24
Abstract: 1,194,567. Disc brakes. BENDIX CORP. 24 Aug., 1967 [1 Sept., 1966], No. 39068/67. Heading F2E. In a disc brake having a disc 14 with a pair of friction surfaces and a pair of friction pads 50, 60 adjacent the disc, a caliper housing 26 is arranged to straddle the disc and is supported by pins and sleeves 64, 96, 82, 94 so as to be slidable axially in grooves 84, 104 of a fixed support 10, and the sleeve is slidably carried by the fixed support 10 for engagement by its respective ends with the caliper housing as it moves axially transversely. A clearance (AB, AC) is provided between the end of the sleeve 82 and the caliper housing 26. This allows limited movement of the housing relative to the fixed support 10 due to lateral displacement of the disc 14. Seals (92, Fig. 6, not shown) are provided at the ends of the sleeves 82 to retain lubricant between the sleeves and pins and to prevent dirt and other contaminants from entering. The sleeves 82, 94 slide in grooves 84, 104 in circumferentially spaced arms 22, 24 of the fixed support 10. Locking screws (78, Fig. 4, not shown) pass through opening (80) in the caliper housing and engage the pins 64, 96 to prevent these pins from sliding within openings 70, 72 in the caliper housing 26. Rattle of the brake members is prevented by springs 106 and 110 which bias the housing 26 so that the manufacturing tolerances of the parts occur to give spaces CD and EF. The spring 110 is bifurcated at its free end 114. The brake pad 50 is attached by projections 52 on the backing plate (56, Fig. 5, not shown) to the caliper housing 26. The other pad (63), Fig. 2 (not shown), slides in the fixed support 10 and is acted on directly by a piston (36) of a fluid motor (28). The piston (36), cylinder (38) and seal (40) are constructed so that the friction between the seal and the piston controls the new starting position of the piston as it moves towards the disc due to pad wear. Also as pad wear occurs the sleeves 82, 94 are repositioned in their respective arms 22, 24 in one direction only and are not shifted back due to the spring loading of the anti-rattle springs 106, 110 so as to provide automatic wear adjustment.

Abstract: 827,755. Chucks. UNITED-GREENFIELD CORPORATION. Dec. 24,1956 [Dec. 28,1955], No. 39219/56. Class 83 (3). A chuck, particularly for holding thin - walled work, comprises a number of pairs of jaws 14, 15 for gripping the work, jaws 26 for centring the work, and means, including a clutch 50, for radially adjusting the jaws 26. The gripping jaws, slidably mounted in pairs 14, 15, each in a radial slot 13 in the face 12 of the chuck-body 10, are operated by screws 16 having a key-socket 18, and each engaging screw-threads on the underside of a jaw 14, and having an annular groove to receive a concave projection on a jaw 15. Bridge clamps 20 secure the jaws 14, 15 after adjustment, and stops 21 at the ends of the slots 13 prevent escape of the screw- and jaw units. The centring jaws 26, adjustably secured on slide-bars 27 in radial slots 25 in the face 12, are operated by a scroll-cam on a disc 32 rotated by the clutch-plate 50, which supports pins 49 engaging slots 48 in a ring bevel-gear 47 rotated by a pinion 46 on a shaft 33 having a key-socket 36. A nut 67 secures the cam-disc 32 between bearings 65 on the hub of a plate 52, radially adjustable in a recess 53 in the face 12 by screw-operated wedges (Fig. 3 not shown), between the perimeter of the disc and the recess, and accessible through holes in a cover-plate 58, to adjust the scroll-cam and jaws. The compression of springs 42, acting between the clutch-plate 50 and a disc 41 driven by the pins 49, and located within a ring 62 retaining the gear 47 in position, may be adjusted through movement of the disc 41 by a screw 76 engaging screw-threads in the hub. The head 70 of the screw has a flange 71, between which and a disc 74, fixed by screws 73, is located a ring 79 having peripheral-graduations to indicate the axial position of the screw, and hence the approximate slipping torque of the clutch. The face of the disc 74 is also graduated and co-operates with an index-mark on the plate 58 to indicate more exactly the setting of the screw. The hub-plate 52 has radial slots to receive the toothed followers 30 on the jaw-slides 27, and the clutch-plate 50 may be formed with bevelled teeth, Fig. 3 (not shown), or, as illustrated, bear against a frictiondisc 51. A key-recess 75 is formed in the end of the screw 76.
