Title: Improvements in or relating to clutch operating mechanism for motor vehicles
Inventor: BLAND ALBERT NORMAN
IPC: F16D48/06
Filed: 1957-03-27
Abstract: 847,942. Friction clutches; clutch control. AUTOMOTIVE PRODUCTS CO. Ltd. March 24, 1958 [March 27, 1957; Aug. 2, 1957], Nos. 10059/57 and 24625/57. Class 80 (2). In control mechanism for a centrifugal clutch of the type having a release bearing movable in one direction to disengage the clutch irrespective of the position of the centrifugal weights and movable in the other direction to permit engagement of the clutch under spring pressure, means are provided to prevent the spring engagement, such means being rendered inoperative at increasing vehicle speeds. A centrifugal friction clutch 10 has a release bearing 21 actuated by a vacuum servo 11. The clutch 10 is mounted on an engine flywheel 27 and has a drive plate 28 gripped between the flywheel and a presser plate 29, the presser plate being urged towards the flywheel by struts 33 acted on by centrifugal weights 31 carried by a reaction plate 25. The reaction plate 25 is urged towards the flywheel by springs located between the plate and the clutch cover 26, and may be moved away from the flywheel by links 24 and release levers 23, carried on the cover 26 and acted on by the release bearing 21, to provide in a left-ward position clutch engagement under the action of the springs, in an intermediate position clutch engagement by the centrifugal weights, and in a right-ward position release of the clutch irrespective of the weights or the springs. The vacuum servo 11 has a movable member 12 subject to atmospheric pressure in space 45 and subjectable to engine manifold depression from a reservoir 39 on opening of a control valve 38 to cause release of the clutch 10. The servo 11 also contains a piston 42 mounted on a sleeve 43 having a stop 46 limiting the movement of the piston 42 under the action of a spring 48 which is stronger than the springs in the clutch 10. A solenoid 52 controls a valve 51 to connect the chamber 44 to the reservoir 39 or to atmosphere. The solenoid is energized when switch 59 is closed, by depression of the accelerator 62, and switch 61 is closed by gear shift being in the upper two ratios, to open chamber 44 to the reservoir 39 and allow atmosphere pressure in space 45 to move piston 42 against spring 48 and thus allow the clutch springs to lock-up the clutch irrespective of the weights 31. In modifications the solenoid is rendered speed-sensitive by the use of dynamo current as by an output shaft driven centrifugal switch. A holding resistance may be used across the switch 59 or may be switched in the circuit by depression in conduit 49 to reduce the current in relay 52. In another modification the valve 51 is operated directly by a centrifugal governor on the gearbox output shaft. In a second embodiment the fulcrum of the clutch throw-out lever is moved by the speed sensitive vacuum servo, and the lever is moved about its fulcrum by a second vacuum servo.

Filed: 1943-06-24
Abstract: 580,960. Reinforced concrete. BILLNER, K. P. June 24, 1943, No. 10235. Convention date, June 17, 1942. [Class 20 (iv)] A method of stressing a reinforcing element 12 in a body 10 of concrete consists in surrounding the element with a zone or coating which is softened by the application of heat, thermally expanding the element with respect to the body cooling the element, and applying at least a portion of the contracting force of the element to produce compressive stresses in the body. In Fig. 1 the body 10 has a reinforcement 12 coated at 14 with a material of low melting point, such as a thermoplastic material, sulphur, or low melting metals or alloys. The ends of the reinforcement are screw-threaded and are fitted with nuts 16 and washers 20. When the concrete has set an electric current is passed through the reinforcement, the current being sufficient to soften the coating 14. The heat expands the reinforcement and the nuts 16 are advanced sufficiently to produce the required compressive stress on the concrete when it cools. In a modification, Fig. 2 (not shown) the concrete body and its reinforcements are curved. In the case of cylindrical bodies the ends 28, Fig. 4, of the reinforcing rings are enlarged, the enlargements being located within a recess 30 in the outer face of the cylinder. When the reinforcement is heated a clip 32 having bifurcated ends is clipped over the ends 28 to enable the reinforcement partially to contract. The recess 30 is subsequently fitted with dry packed concrete 33. In a modification, Fig. 3 (not shown) the reinforcement for a tube is in the form of oppositely wound helices the ends of which have enlargements to receive clips 32.
