To all whom it may concern:

Be it known that l, lVAL'rEn S. imparts, a citizen of the United States, residing at New Matamoras, in the county of Washing.- ton and State of Ohio, have invented certain new and useful Improvements in Antiskidding Attachments for Automobile-Tires, of which the following is a specification, reference being bad to the accompanying draw- %his invention relates to anti-skidding attachments for automobile tires.

One object of the invention is to provide an article of this character that shall be simple of construction, of the highest eficiency and durability in use, and capable of ready attachment to iosition upon atire, the arrangement or the parts bein such as to enable them to resist strain wit out anyappreis better understood, the same consists in the novel construction and arrangement of parts of an anti-skidding attachment for automobile tires, as will be hereinafter fully described and claimed.

lln the accompanying drawing forming part of this specification, and in which like characters of reference indicate corresponding parts: Figure 1 is a view in side elevation displaying the manner in which the attachment is combined with an ordinary twisted link chain; Fig. 2 is a view in side elevation of the anti-skidding attachment, partly in section.

The attachment is constructed from any suitable material, preferably from malleable cast iron, and embodies a semi-band 1 the arch of which will closely approximate spurs 8, each. having a threaded shank 4: and an intermediate nut 5, thespurs being prethfCarried lay-the bend oftheband aretwo erably of hard steel in order to'cause them i to be capable of resisting long continued wear without appreciable deterioration. T he nuts are seated in sockets 6 arranged on the outenface of the band, the sockets being of a depth to house the greater part of the length of the nut, so that the spurs will be free to engage with the surfaces over which the machi ne is traveling, and'th'e nuts will be protected from wear.

in assembling the bands with the chains 7, one being employed on each side of the tire, two ad acent links are slip ed over the pair of lugs at each end of the and, and a wire 8 is then threaded through the orifices 9 of the lugs and the ends of the wire are wrapped or coiled around the lugs, thereby securely holding the chains assembled with the bands. llhe spurs, as shown in Fig) 2, are disposed at outwardly diverging angles so as to insure a most eti'ective gripping or bit ng action in use, and also to space the points of the spurs as far apart as is conslstent with the curvature of the band or the transverse diameter of the tire.

From the foregoing description, it will he seenthat although the improvements of the present invention are simple in character, they will be thoroughly ellicient for the pur pose designed, and will coact in the prcserr tation of a nonskidding attachment that will possess allthe requisites necessary to make such a device of practical value.

Having thus described my inventiomwhat ll claim is:

l. in a device of the class described, the combination of a gripping member adapted to extend transversely of the tread of a wheel, spaced lugs on the opposite ends of said member adapted to project through the ends of adjacent connected links of a chain, and means connecting said lugs and extendin over the connected ends of the chain lin s to retain said tread member in connection with the links.

2. l'n a device of the class described, the combination of a gripping member adapted to extend transversely of the tread of a wheel, attaching chains for retaining the gripping member on the tread of a wheel, and means on each end of said member extending longitudinally of the respective f the chains, and a wire adapted to be concent chain links to hold said member in connected at its ends to said lugs and extending nection with the chains. over the engaged ends of t e chain links to 3.
