Application filed ilay 23, 1918.

To all whom, it may o 120cm: lie it known that I, Janus M. Gnrnn, citizen of the United States, residing at 2M9 rlarrison street, in the city Chicago, and State of illinois, have invented ccrta new 'Hl nseiul improvements in l'Ton- ..d chments tor AutomobiloTires, or which the following is a specification. I My invention skid attachments has for its objects, skid attachment which quicl-zlv put on or s to removable nonautomobile tires, and 1 e providing of nonmay be easily and taken without the use of ra tools; one which is securely locked place when once adjusted against accio ital removal or loss; one which is low in cost; one which produces very slight wear on the tire; one in which breaks may e easily, cheaply and quickly repaired; one which has suincicnt play to shake lose any dirt or matter which may lodge in it; and one which has no angles or pockets where dirt or snow or ice maypermanently lodge to the detriment of its ciiiciency.

ll ith the above and other objects in view, my invention consists of the novel construction, combination and arrangement of parts as are more fully illustrated and described in the accompanying drawings and specifications hereunto appended.

in the annexed drawings, in which like numerals of reference refer to similar parts,

Figure l is a fragmentary elevation of an automobile wheel illustrating the present invention applied thereto.

Fig. 2 is an enlarged plan view of one of the non-skid blocks employed by me.

Fig. 3 is a section view of the non-skid block shown in Fig. 2 taken along the line Fig. 4: is a section view of the non-skid block shown in Fig. 2 taken along the line 6-1).

In illustrating my said invention, 1 have shown a portion of the rim 1 or" an automobe of any usual construction, having the tire 2 attached thereto in any of the customary methods. As shown, my non-skid attachment. consists of a number of non-skid blocks 3, having a circular body portion 4 bearing against the a tire, the inner surface or which is concave, as at 5, with the elges rounded. as at 6 in order to reduce the wear caused by contact Specification of Letters Patent. 1

with the tire to the le: st possible minimum. Er rib "7 extends the length trier-eel which designed to secure the greatest grin upon the roadvmy, to prevent T or skid-- ding.

These ribs '7 extend beyond the a of the body portion i, and in each end thereof have the holes 8 adapted to receive the rings 9 which connect the non-skid blocks together into a continuous string oi e desired length. rrt one end of said s of non-skid blocks 1 have preierably attached a larger ring, as 19. fit the reverse end of said string of non-skid blocks, 1 have prei erably attached a snap hook. at ll, whica is adapted to snap into the ring 10 or any other ring of said string of non-skid blocks and rings lesired in order to attach said string of non-skid blocks upon said tire against accidental detachment or loss. Where the ribs T join the body ii, as at 12, T

have provided fillets, in order to eliminate the possibility ct dirt, snow or ice collecting on said non-skid blocks, and diminishtheir effectiveness in gripping the roadway.

The chain-like device is provided at one end with ring 10 and the opposite end is provided with a snap hook 11. The method of attaching the chain-like device is to first pass the end provided with the ring 10 between the spokes of the wheel. The end having the snap hook 11 is then passed through the ring and the chain-like device pulled upon, forming a slip knot about the ring and tire. The chain is then wound about the rim and tire until the end having the snap hook 11 is brought into proximity to the ring 10 and snapped into engagement with the latter. If the chainlike device should be too long or too short to provide for an effective connection between the ring 10 and snap hook 11, the snap hook could be caught into some link of the chain-like device in proximity to the ring 10. To remove the device, the snap hook is released from the ring 10, and the device is unwound from thetire, and removed from the ring 10. While I have described what I consider the simplest and most effective manner of attaching my device to a tire, it is apparent that it is possible to attach it in many other ways, which may appear to the owner to be fully as effective as that illustrated.

hen attached to the tire, as explained above, my device forms a continuous row with y will be rmgs are ofreasonably fair sized thereby of my non-skid blocks about the tire, with the ribs in contact with the roadway. As the blocks are concaved there is little or no Wear on the tire, and at the same time they'have a large bearing sur face upon said tire. As the rings 9 all lie flatly against the tire,they present no sharp or raised projections to wear the tire, as with ordinary chains, and in addition, have a large bearing surface against the tire, insuring additional gripping surface both against the roadway and the tire. As these diameter, they present little opportunity for dirt or snow or ice to lodge in them, and if it should find lodgment, the vibration of the rings against the tire, as the .wheel rotates, would loosen such matter, and it would fall out. Ihave also, as will beseen, provided fillets where the ribs adjoin the body of the blocks, preventing lodgment of any dirt or ice or snow in the angles thereformed, as might occur, deeply recessed.

Y I y constructing my'said non-skid blocks forming dies, or by casting them, it apparent that they can be produced gain, in case of breakageof a ring, or block, such ring or block 7 may be easily, and quickly removed without special tools, and either another put in its on the inner surfaces,

' adapted onally of the tread of the tire place, or the remaining rings and blocks connected making the devlce as usable as before. hlle I have shown my device with Having thus described my said invention,

what I claim, and desire to secure by Letters Patent, is the following:

A non-skid chain for motor vehicle wheels to be spirally wrapped around the tire and rim ing an inner face to fit the tire Y at its outer face with a rib extending longitudinally of the chain and disposed diagwhen the chain is 1n position thereon, said ribs being extended beyond the body and ings, and connecting links passing through the openings of the ribs.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
