558,796. Starting and regulating. EXACTOR CONTROL CO., Ltd., and REMINGTON, J. G. June 28, 1943, No. 7186/42. [Class 7 (v)] [Also in Group XXIX] A hydraulic remote control apparatus particularly adapted for the graduated operation of a pair of fuel supply valves, controlling the supplies of alternative fuels, one of which may be for starting, to an internal combustion engine comprises a manually operable control unit A actuated by a handle 16 or pedal 19 and operatively connected by a pipe 1 with a power unit B. The piston rod 2 of the power unit is pivoted at 4 to a floating lever 5 the ends of which are coupled by links 8 to crank arms 12 operating butterfly valves 10. The ends of the lever are equally loaded by springs 14,15 the tension of the spring 15 being always greater than that of the spring 14 so that during the initial movement of the rod 2 the valve D is gradually opened while the valve C remains closed. Continued movement of the rod 2 brings one arm of the lever into engagement with a fixed stop 20 ; this tilts the lever in the reverse direction to close the valve D and open the valve C. This reverse movement may be effected by a second control handle connected by linkage or a Bowden cable with the end of the lever 2 loaded by the spring 15. The links 8 may be coupled to the controls for a second engine, and the movements of the lever 5 may also control the ignition timing. Weights may be used in place of the springs.
