Title: Brake applying means for trailers of articulated vehicles
IPC: B60T7/20
Filed: 1962-11-01
Abstract: 1,063,081. Trailer brakes operated by backward pressure of a tractor vehicle. F. J. C. HOPE. Nov. 15, 1963 [Nov. 1, 1962], No. 41399/62. Heading F2E. A trailer braking system of the kind which is operated by backward pressure of a tractor vehicle when the latter is braked comprises a cylindrical rubber block 8 contained in a casing 11 secured to the trailer or, as shown, semitrailer, a king-pin 1 passing through a sleeve 7 in the block and having a key 2 engaging a key slot in a " fifth wheel " 3 of the tractor vehicle, and a device carried by the king-pin whereby substantial compression of the rubber block occurs upon deceleration of the tractor vehicle in both directions of travel of the vehicle, but not upon acceleration of the tractor vehicle, the compression of the block being caused to apply the trailer brakes in the former case. As shown, bores 9 are provided in the rubber block 9 which act as master cylinders, the output pipes 10 being joined to a common system feeding hydraulic trailer brakes. The appropriate bore is deformed to pressurize the system when deceleration of the tractor vehicle occurs in either direction, in which event a cruciform member (19, Fig. 5, not shown), which is pivoted at 18 to the king-pin 1 and has upwardly directed forward and rearward arms 20, 21, is deflected from a rest position, in which it is held by opposed springs 23, owing to inertial force acting on its centre of gravity which is above the pivot 18, whereby in overriding the tractor vehicle the rearward or forward flange 14, 13 of the casing passes below the appropriate arm 21, 20 so that block 8 is conpressed. If, however, the tractor accelerates in either forward or rearward direction, king-pin 1 is pulled forwardly or rearwardly before the cruciform member can respond to the inertial force on it so that an appropriate cam 24 or 25 carried by each of the transverse arms of the cruciform member is moved below a pin 16 or 17 which forces the cruciform member in the opposite direction to that in which it would be moved by the inertial force, causing the appropriate forward or rearward arm 20, 21 to be depressed below flange 13 or 14 into engagement with the casing 11 so that insufficient compression of the rubber block 8 can occur to operate the trailer brakes. Instead of bores 9 in the rubber block conventional master cylinders can be used, operated by links incorporating lost-motion means and connected between the master cylinder pistons and the sleeve 7.

Abstract: 1,074,559. Honing. MICROMATIC HONE CORPORATION. Oct. 11, 1965 [Jan. 21, 1965], No. 42940/65. Heading B3D. A honing machine comprises a honing tool with a honing tool body having a longitudinal opening extending therethrough and including longitudinally extending circumferentially spaced slots, a number of honing stones, a plate for each honing stone, the plates extending through the slots and inwardly terminating in cone blade engaging means, a cone extending within the longitudinal opening, the cone including circumferentially spaced blades, the blades having cam surfaces engaging corresponding cam surfaces on the plates, whereby only one set of honing stones is expanded at a time. A honing tool has rough honing stones 74, finish honing stones 74<SP>1</SP> and guides 75. The stones are mounted in stone holders 73 mounted on plates 72, each having cam surfaces 71 (71<SP>1</SP>). The expanding cone comprises two sets of blades 69, (69<SP>1</SP>) having cam surfaces (70, 70<SP>1</SP>). In one position, the blades are operative to expand the stones 74 and in an angularly displaced position the blades are operative to expand the stones 74<SP>1</SP>. A ring (24), mounted on a part (14) of the tool spindle carries a pin (20) extending through an opening (21) in the part (14) into a vertical groove (19) of a part (18) of the cone push-rod. At the end of rough honing, during which the stones 74 are expanded, the direction of rotation of the tool spindle is reversed and pneumatic pressure from a line (11) is caused to urge a brake shoe (26) against the ring (24), thus altering the angular relationship of the tool spindle and cone push-rod to set up for expanding the stones 74<SP>1</SP>. The two settings are maintained by a pin (40) mounted in a part (37) of the tool spindle and engaging one or other of vertical grooves (39, 39<SP>1</SP>) in a part (35) of the cone push-rod. In a modification (Fig. 11), upward movement of the cone push-rod (77) expands one set of honing stones and downward movement of the rod retracts them and expands the other set. In another modification (Fig. 12) a cone push-rod (81) is oriented by manually moving a ring (82) when the tool body (84) is stationary. In another modification (Fig. 16) orientation of a cone push-rod (89) is effected by vertical movement of a bracket (91).

A rotary pump comprising an annular piston 1, Figs. 1, 2, mounted on an eccentric 3 so that the piston rolls around the inner cylindrical periphery of the casing 2 and a radial vane 6 secured to the piston which is slidably guided between two partcylindrical shoes 7, includes channels 8, 9 in the vane and shoes respectively, connecting a suction chamber on one side of the vane with an intake duct 11 and a delivery chamber on the other side of the vane with a delivery duct 12. In dead centre position of the piston, the channels 9 are closed by abutment faces 10 on the vane to prevent return flow of pressure fluid from the delivery duct to the intake duct. The symmetrical arrangement of the channels permits of pump reversal. A sliding ring 13, between the eccentric 3 and piston 1 includes an annular groove fitted with a resilient sealing ring 14 which permits the piston in its rolling to adapt itself to any imperfections in the surfaces of the piston and casing. Thrust between the piston 1 and casing 2 determines pump pressure and by replacing the sealing ring 14 by another, pump pressure may be controllably varied. Sealing rings 15 supported by O-rings 16 seal the piston with respect to the end faces of the casing and the pumping chamber from the eccentric.
