Abstract
A coupling for coupling a lever to a sensor, e.g., a potentiometer for remote control of the throttle speed of a motor. The coupling includes a die cast housing wherein configured end cavities are interconnected by a through bore. One of the cavities is configured to have bosses that form rotative stops. A bushing is positioned in the through bore and the combination provides a sub-assembly. A second sub-assembly includes a shaft with a cross pin that is adapted to seat between the bosses with the shaft inserted into the bushing. With the shaft assembly seated, a retainer ring is placed on the opposite end of the shaft to cooperatively (cooperative with the cross pin) retain the shaft sub-assembly to the housing. A lever is attached to one end and the other end is connected to the sensor. The spaces between the bosses provide the desired rotative limits for the shaft to generate the range of throttle positions between full throttle and idle.
