Filed: 1965-09-14
Abstract: 1,066,168. Brake linkages. C. M. RUANE. Jan. 17, 1966 [Sept. 14, 1965], No. 39080/65. Heading F2E. In a link work for applying the brakes of a vehicle, a first lever A is adapted to be actuated by a linkage (not shown) connected to the brakeactuating lever or pedal, the first lever A being provided with a shaft A1 which is mounted in a 'bearing held on an adjustable bracket (not shown). A second lever B is pivoted to the first lever by a pin A2 and the second lever B has a shaft Bl slidably connected thereto, the shaft having two arms C, C connected to the linkwork D leading to the brakes of the vehicle such that, in operation, the effective length of the second lever is increased to constitute a variable leverage mechanism. Pressure on the brake pedal will bring the assembly into motion by applying a braking force P to the pin A2 to rotate the levers A and B about the shafts A1, Bl which act as fulcrums. Rotation of the levers A, B causes the lever B to slide through the shaft B1 and thereby increase the effective length of the lever B to achieve the variable leverage result.

Abstract: 1,243,967. Boots &c. RALPHS UNIFIED Ltd. 20 Aug., 1968 [25 Aug., 1967], No. 39134/67. Heading A3B. A method of lasting a shoe upper includes the steps of positioning the upper on a last or form and turning over and securing the lasting margin to the insole before the upper material is fully stressed, the stressing of the upper being carried out subsequently. As described the upper may be lasted on a last 18 (Fig. 1) of the type described in Specification 1,114,241 and which includes a fixed heel part 18a, a fixed sole plate 18b and a movable forepart filler 18c. The forepart filler 18c can be moved forward to stretch the upper by air motor 72 which drives a pin 20 along a cam slot 80 in the support 19 for the forepart filler 18c. The upper is positioned on the last by grippers 35, 36 (Fig. 4) which are mounted on a carrier 32 which can be moved to an inoperative position by air motor 103 acting on parallelogram links 43, 44. The grippers can be moved forwardly by air motor 83 and can also be raised. When the upper is correctly positioned it is clamped against the periphery of the sole plate 18b by a plate 14 (Fig. 1) which has a recess 22 which corresponds to the shape of the sole plate 18b. Wipers 15 are then operated to secure the lasting margin to the insole. The last is then expanded to tension the upper and heat may be applied to set the upper. A sole 57 may then be secured to the shoe bottom by the apparatus shown in Fig. 9. A lever 48 carries a pad box 55 and is movable between a position in which the adhesive on the sole can be actuated by a heater 70 and an operative position (shown dotted). The lever 48 is moved by air motor 51 and is then locked in its operative position by a bolt 60, pressure being applied to the pad box 55 by air motors 58. Alternatively a sole can be moulded onto the shoe bottom using an injection mould (not shown) on the lever 48.

Abstract: 967,723. Oscillatory vane motors. G. D. PETERS & CO. Ltd. Nov. 23, 1960 [Nov. 26, 1959], No. 40217/59. Heading F1F. [Also in Division E2] Adoor operating device comprises an hydraulic pump 5 operated by an electric motor 3 and driving an hydraulic motor 7, the hydraulic fluid passing through a control valve 19 and a non-return valve 20 between the pump 5 and motor 7 and the non-return valve being opened to permit return flow of the fluid as the door closes after a predetermined period. The electric motor 3, which has a belt drive 4 to pump 5, is started by a push-button, or switch or by a photo-electric device or mat operated contacts as the door is approached, and runs until the door is fully open. The fluid passes from the pump by way of conduit 21 to the control valve 19, raises piston 23, passes through a port 25 to the valve 20 and thence through conduit 26 to rotate a vane 6 in sector shaped motor 7 which operates links 9, 11, 13, against the action of a spring 16 connected by cord 15 to pulley 14, to open the door on its axis 2. When the door is fully open the fluid raises piston 23 further against loading spring 24, flows out of the port 27 and raises a piston 28 against the action of a spring 30. After the piston 28 has risen a predetermined height the piston rod 35 engages a microswitch 36 which normally stops the motor 3 to initiate closing of the door. If the user is in the vicinity of the door, closing is delayed by a mat-operated member 64, Fig. 3 (not shown), which keeps the motor circuit closed and the motor running until the user leaves the mat. If the motor is not switched off when the piston 28 nears its upper limit the fluid escapes through a port 33 and returns to the reservoir 17. When the motor is switched off the piston 23 returns to its original position, the piston 28 falls, the fluid returning via the ports 27, 32 of the control valve to the reservoir 17, and when the piston 28 nears the end of its cylinder it engages a rod 37 to open valve 20 to allow the vane of motor 7 to return and close the door, the fluid passing through valve 20 and ports 25, 32 of the control valve to the reservoir. Since the vane 6 covers the inlet and outlet ports 43, 44 of the motor in its extreme positions one-way and bleeder valves 47, 48, 49, 50 are introduced to start the movement and retard the final movement in each direction. A further bleeder valve 41 is fitted across the pump 5 to control the speed of the movements.
