Title: Hydraulic braking system
IPC: F16D55/228
Filed: 1953-12-10
Abstract: 771,829. Hydraulic brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. Nov. 25, 1954 [Dec. 10, 1953], No. 34357/53. Class 103 (1). In order to prevent the friction pads 10 of a " spot-type " disc brake from moving into light rubbing contact with the disc 6 in the inoperative state of the brake, due to the unpressurized head of fluid in the master cylinder reservoir, an annular resilient member 23 is fitted so that the outer periphery is over the open end of the cylinder block 11 nearest the brake disc and the inner periphery is clipped into a recess formed in the plunger extension 15 of the plunger 14 which operates in cylinder 13. The annular member 23 is constructed to allow for wear of the friction pad; the wear being automatically adjusted by mechanisms 18, 19, and the cap also protects the bore of the cylinder from dirt, moisture and the like. The force exerted by the unpressurized head of fluid is overcome by the fact that the annular member 23 exerts a slightly greater force on the plunger 14 in the opposite direction to that exerted by the static head of hydraulic liquid. The Provisional Specification describes an alternative construction in which the force exerted by the annular member 23 to effect withdrawal of the friction pad may be provided, or supplemented by a spring. Specifications 688,382, 747,965 and 747,972 are referred to.

Abstract: 782,975. Making tubular parts; forging. HUET, A. Dec. 17, 1953 [Dec. 31, 1952], No. 35133/53. Classes 83 (2) and 83 (4). A method of making a tubular metal element comprises inserting two or more parallel tubes a, b, Fig. 2, within a female die m, inserting the prongs d<SP>1</SP>, d<SP>2</SP> of a forked punch d into the tubes, connecting the punch and die, whereby they are constrained to move together, heating the ends of the tubes adjacent the punch to forging temperature, and moving the die and punch assembly relatively to the tubes to cause the heated metal to flow into the space between the die and punch and form said tubes over the whole or part of their length into a single seamless tube. In one embodiment two or more tubes a, b, which may be rolled from sheetmetal, are mounted in a split die m with their split ends a<SP>1</SP>, b<SP>1</SP>, Fig. 1, facing each other. The upper ends of the tubes have. previously been united by a weld C. A punch d having prongs d<SP>1</SP>, d<SP>2</SP> projecting into the tubes is mounted in the die and a spacing-piece f, which may be a part of the die or may be releasably secured thereto abuts against the weld C. The tubes are then heated locally by induction or by a blow-lamp flame through an opening in the die, and the punch and die assembly are then moved in the direction of the arrow A to press the tube into the space between the upper end of the punch and the die, which space may be of oval or circular cross-section i, Fig. 1. The punch may be pushed through the tubes or may be pulled through by tie-rods attached to threaded ends d<SP>3</SP>, d4. Alternatively, the tools may be stationary and the tubes pushed therethrough by feed rollers; the latter may be used to form the tubes prior to the forging. A lubricant is preferably used between the tubes and the tools during the forging operation and the tools are cooled by circulation of water. The process may be continued until a single seamless tube of the desired cross-section is formed from the two split tubes, or the process may be stopped so that an " open breeches " tube is produced, Fig. 6 (not shown). The two tubes may be complete instead of split and may be formed by bending a single tube into a return bend and cutting at the bend to form two parallel connected tubes. The fork of the punch d, Fig. 8, may have a projection d<SP>3</SP> and the support-piece f may have a corresponding projection f<SP>1</SP> to facilitate the flow of metal. In another embodiment, Fig. 7, the tubes a, b, rolled from sheet-metal, have their free ends h<SP>1</SP>, h<SP>2</SP> projecting tangentially, which projections are supported in gaps in the die m during the pressing operation which produces a single seamless tube k with radial fins h<SP>1</SP>, h<SP>2</SP>. A component tube a, b may be rolled from sheet-metal in the form of a T or H so as to form fins on the tube. Three, four or more tubes may be united at one end by using a punch or punches having three or four prongs.
