Abstract
Abstract A frame consisting of laterally spaced side members with upturned front ends and connected by cross members has upturned rear hanger straps arranged to pass under and behind a lower torsion bar of the front wheel suspension of a small car. The upper ends of the hanger bars curve forwardly to engage over the top of the upper torsion bar of the suspension. L-shaped bolts pass through the hanger bars above and below the torsion bar to clamp the hanger bars to the bottom of the side members and secure the frame to the torsion bar. Thrust plates secured to the side member engage the front of the torsion bar. A towing hitch is pivotally connected to the upper ends of the L-shaped side members.
