To all whom it may-concern:

Be it known that I, FREDERICK TAYLOR Gauss, a. citizen of the United States, re-

siding at Wilmington, in the county of New Castle, State of Delaware, have invented certain new and useful Improvements in Tire Chains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to tire chains used in connection with automobiles or other pneumatic tired vehicles for preventing skidding of the vehicle and increasin the tractive grip of the tires.

ire chains as now commonly constructed comprise a pair of side chains with hooks or other fastenings in their ends and a series of cross chains connecting the two side chainsat intervals of'five or six inches. The side chains are of a length such that when their ends are hooked together they form rings of slightly greater circumference than the wheel rim and lie symmetrically on opposite sides of the tire.

In putting chains of this character on the wheel it is necessary t lay them out in line with the wheels and move the vehicle so that the wheels rest properly upon the cross chains, after which the ends of the side ,chains are drawn up over the wheels and "secured together. It is frequently difi'cult to bring the ends of the side chains together due to the slack caught under the vehicle wheel, or other cause, and even after one side chain has been hooked it is very commonly difficult to draw the ends of the other side chain together by hand and hook them.

To put on chains of this character thereis necessarily a great deal of handling of y the chain and reaching through and around the wheel, which is always a tedious and dirty 'ob. Since tire chains are noisy and somew at injurious to the tire they are invariably carried in the vehicle and put on the tire only when necessary, frequently after rain has started and the road has become muddy. These conditions add to the inconvenience of applying the chains and consequently compel the driver to remain outside the car for a longer time.

It is accordingly an dbject of the present Application invention to provide a tire chain which may be readily put on the 'tire without moving the vehicle on to the cross chains.

It is also an object of the present inven tion to provide a tire chain which easily applied to the tire and secure place with a minimum amount of handling and reaching around the wheel.

A further object is to provide a tire chain in which the proper tension between the free ends of the side chains is conveniently secured and is maintained until the user desires to remove the chain, atwhich time the chain may be loosened and removed in an easy and convenient manner.

I have illustrated a preferred embodiment larly to Fig. 3, 1 and 2 1ndicate, respectively, the two side chains, and 4 the cross chains comprising an ordinary tire chain of the type commonly used on automobile wheels, and the like. .The chain 1 is preferably of a length greater than is necessary to surround the wheel when the tire chain is in place, the excess length preferably having the form of an extensionfi, which may be one-fifth to one-quarter the length of the side chain so as to extend well be end the point where the ends of the c ain are" oined. A hook6, or some other suitable fastening, is provided at thefree end of the extension 3 for engagement with the bod portion of the side chain 1, as will belater described.

The other end of the side chain 1 is provided, preferably at its juncture with the last cross chain 4:, with a ring 5 large enough to slip freely over the extension 3 provided at the other extremity of the side chain 1. Beyond the ring 5 and the juncture with the last cross chain 4, the end 7 of the side chain is extended across to the adjacent and of the side chain 2 which is extended bese, i

yond the point of attachment of the last cross chain 4, the ends of the two side chain so that it may be conveniently em ployed in securing the free ends of the side chain 2 together when the chain .has been placed in position upon the tire.

In applying my improved tire chain to am'automobile or similar wheel, the chain is first laid u the tire in suchmanner that the midd e of the chain falls approximately at the top of the tire with the ends of the chain lying on the ground in front of and behind the point of contact of the wheel and the pavement. The side chain 1 is placed on the inside with the extension 3 toward the front/of the vehicle when the chain is applied to the rear wheel. The body of the chain is then settled into place around. the larger portion of the periphery of the wheel, whereupon the extension 3 of the side chain 1 may be conveniently grasped at its position in advance of the tossed backward on the inside oi the wheel so that its end 6 may easily be reached from behind the wheel and slipped into its position through the ring 5. A pull exerted on the extension 3 will then pull uptheside chain 1 into proper tension, the lowest cross'chains 4 being normally at a suflicient distance apart so that this operation'may be easil and conveniently performed, even thong the bottom of the tire be resting upon'soft or muddy ground. Af-

tor the side chain 1 has been pulled up into a sufliciently taut condition it is retained in position by hooking the member 6, provided on the extremity of the extension 3, into one of the linksalong the side chain 1. The

ring 7 a which is provided to connect the adjacent extremities of the side chain 2 and the cross extension 7 of the side chain 1, is lying at the rearward side of the wheel and at the outside of it, in which position it is readily accessible for connection to the other end of the side chain 2 for securely fasteni the entire'ch-ain upon the wheel.

The connect-ion between the free ends of the side chain 2 may be accomplished in any desirable manner, but I preferably emplpy for the purpose a fastening member such as shown in Fig. 5, consisting of a rod or heavy wire 8 slightly curved throughout the greater portion of its length, as shown, and provided at one end with a' other end of the rod 8 is provided with a length of light chain 11 which may be provided at its extremity with a hook 12adapted, to be caught into a link of the side chain 2. The fastening member 8 may be carried apart from the tire chain if desired, but I preferably arrange the bent part 10 to be permanently associated with the end 2* of the side chain 2. When .in this position the chain 11 pro-vided at the extremity of the rod. 8 is threaded through the connecting link 7 and the adjacent end of the rod 8 also brought through the ring. A turning force is then exerted on the end of the rod 8 and the adjacent ends of the chain will be drawn together by the lever action which is obtained through the rod 8. It is to be noted that as the ends of the chain are brought closer together, the ring 7 slides down the rod 8 and the leverage constantly increases so that a very considerable tension can be applied between the adjacent chain ends without undue exertion on the part of the operator. After the rod 8 has been turned into position substantially parallel with the extent of the side chain, the loop portionlO will lie between the end links of the side chain2 and.

of applying my improved chain to the ve-- hicle tire may be accomplished without moving the vehicle and without undue effort on the part of the operator, and without reaching through and over the wheel which makes the operation of utting on the ordinary chains a dirt an disagreeable job. The lever arm 8 o the fastening member is sufiiciently long so that it easily spans the distanoe between adjacent ends of the .side chain when the chain is draped loosely over the tire. I have found that the powerful lever action obtained when drawing the ends of the chain into operative position serves to easily and conveniently bring the free ends of the side chain to closely adjacentv amount. When the vehicle is setin mo- 1 tion the diagonal chain 7 will assume a true position extending over the top of the tire and will introduce no appreciable slack in the chain.

I preferably emplgy a single diagonal chain 7, as shown in 1 3, but I may also employ a pair of such 0 ains in the manner as shown m Fig. 4. Each end of the side chain 1 is provided with an extension 7' and the ends of the side chain 2 extend equal distances beyond the lowest cross chains 4, so that when the chain is laid out flat, as

shown in Fig. 4, each of the diagonal chains 7' forms the hy othenuse of the right triangles whose si es consist of cross chains 4 and the extensions of the side chains 2. The ap lication of this chain to the tire is accomp 'shed in substantially the same mannor as has been described, the" fastening member 8 being applied between the apexes of the two f'i 'ht triangles of which the diagonal chains form t e diagonal sides.

I have illustrated and described my preferred embodiments of the invention, but it is to be understood that various changes may be made within the full scope of the appended claims. The lever 8, although it provides an easy means of securing the chain in place, may be dispensed with and a fastener of the ordinary type used instead. Likewise, the forming of t e various chain extensions may be accomplished by an 'essentially unified structure or by means of sepasubstanti rate len s of chain riveted or otherwise secured in proper place, and other similar changes may be made.

I claim:
