Abstract: A control lever assembly includes a mounting bracket on which a control lever and detent plate are supported. The bracket presents a generally planer sliding surface in which a detent element is formed. The control lever and detent plate are supported on the bracket for movement across the sliding surface, and the detent plate includes a finger that is supported for pivotal movement about an axis extending in a direction parallel to the sliding surface. A pair of opposed side walls are provided on the detent plate for guiding the pivotal movement of the finger while preventing the finger from shifting relative to the plate along the pivot axis of the finger. A spring is provided for biasing the finger against the sliding surface so that when the lever is pivoted to a position in which the finger is aligned with the detent element, the finger is forced into engagement with the element and holds the lever in that position.

Abstract: A twistable type throttle-grip assembly especially adapted for use with motorcycle-like vehicles manipulates a single control cable and is normally operational in a first rotational range for controlling the supply of fuel to the vehicle's internal combustion engine thereby controlling the vehicle's speed and is provided with an integral latch mechanism which may be operated by the thumb of the operator while holding the hand grip to release the hand grip for rotation into a second rotational range associated with the operation of a cable controlled, combustion cylinder compression release device on the engine to turn off the latter and permit manual pedaling of the vehicle.
