Title: Improvements in or relating to centrifugal clutches
IPC: F16D43/08
Filed: 1961-02-03
Abstract: 980,582. Friction clutches; variable-speed gears. REGIE NATIONALE DES USINES RENAULT. Feb. 3, 1961 [Feb. 6, 1960], No. 4184/61. Headings F2C, F2D and F2L. A centrifugally engaged friction clutch has a centrifugal weight carrier which also forms a planet carrier for planetary members which frictionally engage a plate fast with an engine shaft and a sleeve splined to a driven shaft which forms the input shaft of a gear-box. Centrifugal weights 21 are slidable on pins 11 mounted on a carrier 9 and have ball bearings 20 engaging an axially fixed plate 22 which is fast with an engine shaft 31 and a cam plate 24 which is displaced axially as the weights 21 move centrifugally outwards. Cam plate 24 acts through springs 26 on a presser plate 27 clamping a driven clutch plate 29 against a driving plate 30. The carrier 9 forms a cage for balls 18 frictionally engaging a race on the plate 22 and race on a sleeve 10 which is splined to a driven shaft 3 and urged rightwardly by a spring 5. On starting, with the shaft 3 and sleeve 10 stationary, the plate 22 drives the carrier through the balls 18 and the weights 21 slide outwardly to gradually engage the clutch against the force of disengaging springs 28. Drive to the weight carrier 9 is broken and the carrier braked, thus disengaging the clutch, by energizing an electromagnetic brake 7 the armature 8 of which is fast with the carrier 9. The carrier and the sleeve 10 are thereby withdrawn and the balls 18 cease to engage the plate 22. To enable the vehicle to drive the engine e.g. for push-starting, clutch shoes 13 are moved radially inwardly to frictionally engage the periphery of the driven plate 29 by levers 14 fulcrumed at one end in centrifugal levers 1 which are pivoted on a driving member and are urged inwardly by a spring 15. As the engine speed picks up the levers 1 pivot outwardly and the shoes 13 move outwardly to release the clutch plate 29. In a modification the balls 18 are replaced by conical friction rollers. The carrier 9 is formed by parts 9A, 9B connected for rotation together by interpenetrating fingers between which the driving balls 18 are interposed.

Filed: 1967-01-27
Abstract: 1,182,842. Adjusting agricultural machines. J. SALMON. 2 Jan., 1968 [27 Jan., 1967], No. 4246/67 Heading A1F. An agricultural machine comprises a wheeled trailer adapted to be attached through a drawbar 5 and pivotal link 6 to a tracter, a cutter or a lifting shave rigidly attached to the trailer's chassis and a pivoted feeler arm 9 which controls the position of the cutter or shave relative to the ground via a fluid pressure operated system. The feeler arm has an arcuate shoe 10 which rides over the ground and is pivotally attached to the trailer. The control plate 23 attached to the top end of the feeler arm engages with the extreme end 24 of the valve element 22 and hence controls the flow of fluid from conduit 19a to the valve. In the uppermost position of the feeler arm the valve is closed and the build up of pressure in pipe 20 actuates ram 16 and crank 12. Link 6 is lifted and the trailer pivots upwards taking the shave with it. The feeler arm falls under its own weight thereby opening the valve again. With the feeler in its lowest position, no pressure is exerted on the ram and the weight of the trailer causes the crank to pivot downwards and to move the ram into the position shown in Fig. 2.

IPC: B67B3/02
Filed: 1924-02-19
Abstract: 222,753. Flower, J. W. Feb. 19, 1924. " Crown corks," applying.-In a machine for fixing " crown corks " on bottles, the bottles are raised to a fixed crowning-head 3 by an hydraulic ram 8 operated by a pump 6, to which it is connected by a passage 7 provided with an adjustable spring-pressed relief-valve 10 which opens to return fluid to a container to prevent the pressure on the bottle from becoming excessive, the device thus adapting itself automatically to bottles of varying size. The return movement of the pump, which is actuated by an eccentric 14 on a shaft 13 adapted to be clutched to a, continuously-rotating wheel 24 by movement of a foot-lever 17, draws in fluid through an inlet valve 12 to replace that discharged through the valve 10. As shown, a shaft carrying a pinion 26, in mesh with a gear wheel 25 on the shaft 13, drives an agitator in a hopper in which the " crown corks " are stored. According to the Provisional Specification, the bottle, in rising, lifts a rod in the crowning head and the rod actuates a ratchet mechanism which drives the agitator, a flywheel on the shaft of the agitator ensuring practically continuous rotation thereof. The bottle table may support several bottles and be intermittently rotated, a cam which drives the pump providing a pause each time the ram is in its lowest position to allow the table to move to its next position.
