Abstract: A motorcycle engine stabilizer that is adapted to be positioned between the engine cylinder head and the motorcycle frame. The stabilizer includes an internally threaded sleeve that is adapted to receive an externally threaded adjustment rod that includes a cylindrical end adapted to bear against a frame tube surface adapter. The adjustment rod includes opposed flat surfaces adapted to permit a tool to engage the adjustment rod for threadedly extending it into or out of the sleeve. The frame tube surface adapter is positioned between the adjustment rod end and the frame. Rotation of the adjustment rod causes the surface adapter to engage a portion of the frame and causes the threaded sleeve base plate to engage the engine cylinder head, thereby providing additional support for the engine and reducing engine vibrations. A space plate having cooling channels can be positioned between the base plate and the engine cylinder head to prevent localized hot spots in the engine cylinder head.

Abstract: A hand operated automobile brake and accelerator operation assembly for the handicapped can be readily transferred from car to car without tools and is adaptable to various models of cars. It is installed by clamping onto the brake pedal shaft with manually operable wing nuts or the like as the sole fixed connecting bracket on the car. The brake pedal and accelerator pedal are respectively operated by pushing and pulling by hand an operating rod to move an operating lever fulcrumed on a pivot axis fixed relative to the brake pedal shaft. This operating lever moves an accelerator operating shaft into contact with the accelerator pedal to depress it as the hand operated rod is pulled. Conversely when pushed the hand operated rod depresses the brake pedal and release the accelerator. To accommodate different car models an accelerator operating shaft has a manually operated lock to fix its length, and the acclerator assembly distance from the brake is adjustable.

Abstract: A device for manually operating the brake and accelerator pedals of a vehicle. The device is removably clamped to each of the conventional brake and accelerator pedals of a vehicle and includes a control lever that extends between respective pivot points that are fixed relative to and spaced outwardly from each of the brake and accelerator pedals. The control lever includes an outwardly extending portion that extends beyond the brake pedal in a direction opposite from the accelerator pedal, and a control handle is pivotally connected at the outer end of the lever extension. The control handle is operable by the user, and when pulled in a direction toward the user the device causes the braking actuator to move in a brake releasing direction while simultaneously causing the accelerator to open the throttle and thereby permit the vehicle to move.
