MAXIME LORME, 0F LONDON, ENGLAND.
ANTISKID-STUD.
To all whom t may concern Be it known that I, MAXIME LORME, a citizen of the Republic of France, residing at 9 Bread Street Hill, London, England, have invented a new and useful Improved Antiskid-Stud, of which the following is a specification.
This invention relates to an improved stud for attachment to boots and shoes and more particularly to the treads of yielding tires of the wheels of motor vehicles, with the object of lessening or eliminating the tendency of the tread to slide relatively to the surface of the road, the stud being of the kind in which a plurality of asperities of unequal prominence are provided which will in suc cession come into contact with the road as the stud wears away.
According to the present invention the central portion of the face of the head of the stud is concave and the surrounding portion thereof is conical and the asperities of unequal prominence consist of facets on the concave central portion.
The accompanying drawing shows alternative varieties of studs according to the present invention.
In this drawing Figures l, 2 and 3 are respectively a plan, a side elevation and a` sectional elevation of one form of construction. Figs. li, 5 and 6 are corresponding views of a modification.
In these figures, the face of the head of the stud which is presented to the road surface is concave in its central portion, the outside boundary being conical. The concave portion is so formed as to furnish sets of facets a situated at graduated distances Specification of Letters Patent.
Application led November 16, 1912.
Patented July i, 1913.
serial No. 731,890.
from the road surface. Wvhen the set which occupies the outer border of the hollow of the stud surface becomes worn, another set of facets a, which is initially protected against wear by being situated within the hollow of the concave surface, comes automatically into operation. rIhe outside conical wall is formed with teeth Z) somewhat like those of bevel-wheels.
The construction shown in Figs. 4 6 differs from that last referred to in respect to the fact that a set of asperities c are provided on the outer conical wall, the teeth Z) of the conical surface making contact with the road when the set c between the inner border of the cone and the outer border of the hollow becomes worn.
The shanks of the studs may be screwthreaded and screw-driver slotways may be formed in their heads to enable them to be screwed into the treads.
I claim:
l. In an non-slipping stud, a head having a concave central face portion surrounded by a conical portion and facets on said concave portion.
2. In a non-slipping stud, a head having` a concave central face portion surrounded by a conical portion, facets on said concave portion and asperities at the edge of said concave portion.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
