SPEED AND CLUTCH CONTROL FOR ENGINES INCLUDING SHIFT INTERLOCK

摘要

Disclosed herein is a control for the throttle valve and clutch of an engine, including a timer plate which is oscillated to concurrently adjust the spark and the setting of the throttle valve and a shift lever for shifting the engine clutch. The control includes a shift interlock which is connected to the shift lever for movement in response to movement of the shift lever and a radially outwardly extending projection on the timer plate. The shift interlock includes a portion which is located to extend into the travel path of the timer plate projection and is engageable with the timer plate projection for selectively controlling the setting of the throttle valve in accordance to the position of the shift lever and for selectively controlling the position of the shift lever in accordance with the setting of the throttle valve. A spring member formed as an integral part of the shift interlock releasably engages a detent pin to positively retain the shift lever in any one of its positions.
