Claims21
A traction device for a tire on a driven wheel of a motor vehicle, comprising:
- a) a base adapted for resting circumferentially upon a tread of a tire;
- b) means for securing said base to said tire, said means for securing including an adjustable clamp assembly extending from first and second longitudinal sides of said base for holding onto side walls of said tire for applying pressure against both sides of said tire for securing said traction device to said tire, said adjustable clamp assembly including a rear jaw, a front jaw, means on said first longitudinal side of said base for adjusting in a retained coarse manner said rear jaw, means on said second longitudinal side of said base for adjusting in a retained normal manner said front jaw, and means on said second longitudinal side of said base for adjusting in a retained fine manner said front jaw so that said rear jaw and said front jaw will butt up against opposite side walls of said tire;
- and,
- c) means for providing traction for said tire when said tire is stuck on ice, snow or other slippery road surface, said means for providing traction located on said base.
