Abstract
A tow bar apparatus has a pair of socket members adapted to be attached to a towed vehicle and a pair of ball rod end joints adapted to be attached to a towing vehicle. The pair of socket members each includes a girdle around a sidewall, the girdle being adapted to support the sidewall to prevent the sidewall from bending out of shape under the stress of towing; the girdle further including a first bolt aperture opposite the bar slot of the sidewall for pivotal attachment of the socket member to the towed vehicle. The ball rod end joint includes an external ring attached to the second end of one of the tow bars, and an internal ring pivotally mounted within the external ring. The internal ring is adapted to be mounted on a post of the towing vehicle.
