Abstract: A safety device for locking a plurality of operation levers, the device comprising a frame on which the levers are mounted for pivotal movement with respect thereto, two lock plates mounted side by side on the frame for movement towards and away from one another between locked and unlocked positions of the device in response to rotary movement of a cam disposed therebetween; a respective link pivoted to each of the levers having its free end supported for linear reciprocal movement in response to the pivotal movement of the respective lever, the link having an engaging portion which co-operates with an engaging portion on the respective lock plate on movement of the lock plate towards the locked position to lock the link against the said reciprocal movement.

Abstract: A fluid pressure control system for automatic transmission includes a fluid pressure source, a fluid pressure regulating valve for regulating the fluid from the source to a particular line pressure, and a plurality of frictional engaging devices, adapted to be actuated by the line pressure through means of a manual shift valve, for attaining a particular gear ratio within the gear trains of the transmission which are interposed between the input and output shafts. A governor valve generates a governor pressure in response to the rotational speed of the input shaft, a throttle valve generates a throttle pressure in response to the engine throttle valve, shift valve selectively actuates the frictional engaging devices in response to the governor and throttle pressures, and a reducing valve actuates to restrict the throttle pressure to a threshold calibration value when the throttle pressure exceeds the value.

Abstract: A self-loading limited slip differential is disclosed including differential pinion and side gears having conical back surfaces, and torque-responsive wedge means operable by said pinion gears for applying frictional torque bias to the driven shafts via the side gears. The wedge means includes conical wedge elements that are displaced inwardly by the pinion gears upon the application of torque to the differential casing to force the side gears apart into frictional engagement with corresponding conical portions of the wall surfaces of the differential casing.
