Title: Improved means for actuating a friction pad in a disc brake
Inventor: HARRISON ANTHONY WILLIAM
IPC: F16D55/2255
Filed: 1963-03-16
Abstract: 1,029,945. Disc brakes. GIRLING Ltd. March 4, 1964 [March 16, 1963; May 28, 1963], Nos. 6380/63, 10506/63 and 21215/63. Heading F2E. Means for applying a friction pad 10 to a rotatable disc comprises a rigid rocking lever 13 angularly movable about a statuary fulcrum at 15 to engage one end of a thrust-member 26, 27 which at the other end bears on a plate 11 carrying a brake-pad 10 and is movable, at least at the end engaged by the lever, in a direction transverse to the line of action of the lever. The lever is actuated hydraulically by the rod 16 of a piston 17 or by hand by a cam 19 rotated through an arm 22 and shaft 21. The pad 10 is mounted in a caliper pivoted at 34 at right angles to the disc 20 so that it can swing to bring a second friction pad (not shown) into operation on the other side of the disc. The thrust-member comprises a plunger 27 adjustably screwable into a sleeve-nut 26 held by a spring 29 in a cylindrical shell 28 by a blade spring (not shown) in such a way as to permit transverse movement. As the pad 10 engages the disc contact between the lever 13 and the cam 25 on the thrust member changes from sliding (Figs. 7 and 8, not shown) to rolling and at the same time a pawl 33 on the lever is drawn from its engagement with one of a number of ratchet teeth 32 around the sleevenut. If there is excessive pad-wear the pawl 33 will over-ride the next tooth to that at or during application of the brake so that, when the lever 13 is released and is returned to rest by a spring 23, the pawl will rotate the sleevenut to take up slack. If due to swelling of the pad 10 an axial load is maintained on the thrust-member after the brake has been released the spring in the casing (Fig. 3, not shown) allows sufficient transverse movement of the latter in the sleeve to prevent the pawl 33 from being damaged.

On movement of the rod 4 and pistons 3, 5, e.g., rightwards, the arm 26 compresses the spring 22 and holds the stop 20 against the horizontal limb 29a of the lever 29 until the pins 28 on the arm 26 engage the lever limb 29b to release the stop 20. The spring 22 then rapidly moves the rod 10 and the slide valves 8, 11 rightwards to reverse the connections to the engine and pump and the direction of movement of the pump and engine.
Patent GB-625310-A (GB)
Title: Improvements in or relating to the manufacture of flexible joints or supports
IPC: B25B27/28
Filed: 1947-03-17
Abstract: 625,310. Resilient mountings. THIRY, L. F. March 17, 1947, No. 7316. Convention date, March 20, 1946. [Class 108 (iii)] In the assembly of resilient mountings of the kind in which a rubber bush is held under axial and radial stress between inner and outer rigid sleeves, the bush is engaged within the outer member and the inner member is forced axially into the bush so that it is radially compressed and axially elongated, while that end of the bush which is last compressed by the entry of the inner member abuts an axially-movable support having a resilient facing member in contact with the end of the bush. As shown in Fig. 1, a resilient bush 2 is inserted into an outer metal sleeve 1 which is then placed in a holder 4 so that the bush 2 is supported on its face 16 by the resilient end 35 of a piston 6 which can slide in the holder 4. A support 32 on a vertically-movable rod 11 carries a standard 10 on which is placed the inner member 8 which is to be inserted in the bush 2, and a conical leading member 14 is carried in the bore of the tube 8. To insert the tube, the rod 11 is forced down and the member 14 enters the bush 2 and is followed by the tube 8. As the member 32 descends, its surface 34 engages a roller 33, carried by a lever 28. The lever is thereupon rotated, carrying with it arm 27 which, through the link 26 and lever 21, lowers the piston 6 allowing the bush 2 to expand in a downward direction. The downward movement of the piston 6 is arranged to be half the total expected expansion of the bush so that the latter is left symmetrically placed between the sleeves 1, 8. The movement of the piston 6 can be adjusted by nuts 23, 24, and a spring 7 normally holds it in position. In a modification, Fig. 4, a spring- controlled piston 6a replaces the mechanicallycontrolled one. The piston 6a moves against the resistance of a spring 36. The upper and lower limits of movement of the piston are set by a stop 50 and a screwed sleeve 38, respectively. The tension in the spring, and so the way in which the piston moves when the plunger enters the bush, is controlled by a threaded cap 37. In another arrangement, Fig. 6, the operation of inserting the bush into the outer sleeve and the inner sleeve into the bush are performed almost simultaneously, the holder 4b having a funnel-shaped entry 60 into which the bush 2 is placed. A carrier 63, in which the rod 11 is slidable, has a standard 61, the end of which is faced with resilient material 62; the standard forces the bush into the outer sleeve just before the descending rod 11 forces the inner'member 8 into the bush. The carrier 63 is operated by a spring 75 and retracted by a compressed air cylinder 72. The rod 11 is independently operated. Specification 243,679, [Class 108 (iii)], is referred to.
