Abstract
Abstract A portable vehicle traction track for freeing vehicles from ice and/or snow without having to raise the vehicle wheel. An extending smooth-bottom tongue contiguous to one end of the track permits easy insertion at the juncture of the tire and the snow. Rotating action of the tire against the upper abrasive surface of the tongue then pulls it completely under the tire. Further movement of the track is prevented by a plurality of grippers on the bottom surface of the track coming to the point where the vehicle weight is pressing them into the snow. The tire then moves along the surface of the track, out of the depression in which it previously rested.

Claim 1
Independent Claim
196 words
A vehicle traction track for pRoviding a traction surface between a vehicle driving wheel and a slippery surface, said traction track comprising: An elongated flexible member having a pair of spaced broadsides, Abrasive means fixedly attached to one of said broadsides and extending the length and breadth thereof, A plurality of ridges along said other broadside, said ridges equally and parallely disposed and extending transversely to the direction of length of said elongated member, A plurality of spaced apart metallic grippers embedded into and extending away from each of said ridges, and An elongated tappered flexible member having a pair of spaced broadsides extending in the direction of length from one end of said elongated member, one broadside of said tapered member having abrasive means attached thereto and lying in the same plane with said one broadside of said elongated member forming a continuous surface therewith and the other broadside of said tapered member being a smooth surface, Whereby said smooth surface of said tapered member permitting the traction track to be pulled under the vehicle wheel until said grippers are embedded in the slippery surface and the driving wheel moves along said abrasive continuous surface.
