Description: |
| Abstract:
The primary object of my invention to obtain in a single lug all the advantages of both yielding and non-yielding lugs without the objections or disadvantages of either considered separately, so that under certain conditions the yielding capacity of the lug will prevent undue cutting or breaking by the non-yielding or biting member thereof, with the result that the latter will not be brought fully into play until a portion of the weight has been taken up by the yielding member, and thereby present a broadened frictional face. to the road-bed.
Claim:
A traction-wheel lug comprising a nonyielding road-engaging base member having biting edges, and a second road-engaging member of yielding frictional material located between said biting edges and normally projected beyond and designed to move inwardly within the plane of the face of said base member so as to present a broad frictional contact surface when under maximum weight. |
