ABSTRACT:
An improved tow bar assembly used to tow cars or trailers located on uneven terrain. The assembly uses two tow bars. One end of each tow bar is attached to a bumper housing. Each bumper housing is removably clamped to the bumper of a disabled vehicle by a chain which has one end secured to the undercarriage of the vehicle and the other end engaged to a chain hook member. The chain is pulled tight by tightening wing nuts threaded onto the upper end of a bolt which causes a spring located between the wing nuts and the top of the bumper housing to pull the chain tight. A socket member located where the other ends of the tow bars join together engages a ball member mounted on a supporting structure of a tow vehicle providing a universal-type joint. The socket member is secured to the ball member by a rotating latch member which uses a pin to prevent the latch member from rotating relative to the socket member, effectively locking the socket member to the ball member. The socket member and rotating latch member have arcuate-shaped depressions or cutaway surfaces therein which facilitate rotation of the socket member with respect to the ball member.
