Abstract
395,692. Driving and controlling motor vehicles. GILLETT, E. H. J. C., 51, Priory Road, West Hampstead, London. Jan. 14, 1932, Nos. 1096. 3375, 3376, 10608, and 15228. [Class 79 (v).] Upon a vehicle having an engine and a clutch, the clutch is operated by an enginedriven governor through a servomotor using fluid with positive pressure. Oil from an engine-driven pump 76, Fig. 2, passes, when the engine is idling, through a relief port 81 and through pipes 85, 83 to drain. Upon accelerating, a governor 94 driven by a train 100 from the engine lifts a stem 90 with a pressure-balanced valve 79 so as to close the port 81 and cause a piston 72 to move leftwardly in the cylinder 71 thereby engaging the transmission clutch and starting the vehicle. This piston stroke extends a strong spring 27 which normally holds the clutch disengaged by pulling a lever 23 and pressing a lever 33 against a cam lobe 22 on a shaft 20 which carries a lever 19 acting on a clutchdisengaging collar 18. A clutch-disengaging spring 86, Fig. 2a, is thus normally held overpowered by the spring 27. The governorfreed hydraulic piston stroke disables the spring 27 so as to allow the spring 86 to engage the clutch 17. The engine-driven governor body is a dished member 97, Fig. 3, with crossed slots 96 carrying governor balls 95 which by pressing on the inside of an inverted cup 94, Fig. 2, raise the latter and with it the valve stem 90 against a spring 91 which is adjustable at 92 to adjust the speed of the engine which will start and stop the vehicle. The balls 95 after raising the cup 94 are confined safely by a rim on the body 97. The vehicle stops with the clutch disengaged, but the clutch may be engaged for manoeuvring in a confined space by depressing a pedal 29 fully and releasing it. A lug 32 on the pedal lever engages the lever 23 so as to extend the spring 27 as in the piston stroke. A spring pawl 34 engages under a heel 25 on the lever 23 so as to lock the servomotor out. On release of the pedal 29, the clutch 17, Fig. 2a, is put in by its spring 86. The pawl 34 is connected by a lost-motion link 37 and Bowden wire 67 to a button 68 on the dashboard which is thus a preselector, operative after the power stroke, for suppressing or permitting the action of the power means. The power stroke would disengage the clutch if the relief valve were arranged to be open except when the governor speed falls too low. When the piston 72 reaches the end of its stroke as shown, it uncovers a port 84 through which and through a second branch pipe 85 excess oil escapes to the drain 83. A second relief valve 80 is shown by which when a change-speed transmission is operated, the hydraulic system is cut out, and the clutch opened. A plunger pump which delivers oil in volumes proportional to engine speeds may be used instead of the gear pump 76, Fig. 2.
