Abstract: A single lever control unit for sequentially operating a transmission and throttle and, selectively, for operating the throttle independently of the transmission. A throttle shaft assembly disengages from a throttle gear by pulling out the shaft while in the neutral position. A double key on the throttle shaft disengages from a keyway in the throttle gear and a spring-loaded pin engages a cavity in the throttle gear to lock both shift and throttle gears in the neutral position.

When the hand lever is returned to the neutral position, the throttle shaft automatically engages the throttle gear and the locking pin automatically disengages by means of spring loading. The locking pin prevents pulling out the shaft in other than the neutral position.A spring provides axial loading between the throttle arm connected to the shaft and a friction plate mounted on the shaft. This loading creates a frictional drag which prevents throttle creep.
