Matter enclosed in heavy brackets reissue specification; matter printed in This invention relates to'non-skid tire chains for motor vehicle wheels, and has for one of its principal objects the provision of tire chains that may be quickly and easily applied to modern automobile wheels without jacking up the vehicle. Many drivers, particularly those who travel principally on paved streets or roads, are desirous of driving as long as possible without chains, to avoid unnecessary wear on tires and chains as well as the noises and vibrations usually incident to tire chains. When, however, inclement weather conditions necessitate the use of tire chains for safe driving they desire to apply the tire chains quickly at the side of the road or street wherever they happen to be, without jacking up the vehicle or individual wheels thereof, or rolling the car wheel onto the chains to allow attachment to the tire of the wheel. My improved tire chain has been designed to meet the demands of such drivers.

Another object of this invention is the arrangement of fastening means for tire chains that will enable quick application of the chains on wheels of automobiles having fenders that overlap a large proportion of the wheels and the central portions of the wheels are not provided with apertures of sufficient area to permit handling of the inner side chains therethrough.

An auxiliary and more specific object of the invention is the provision of fastening means or attachment for tire chains including a pair of clamps connected by an intermediate length of chain adapted to serve as one of the anti-skid. cross members of the tire chain wherein the clamps assure that the tire chain remains in position on the tire should this anti-skid cross member connecting them become accidentally broken in use.

A further object of this invention is the provision of a tire chain having inner and outer circumferential side chains connected at intervals with anti-skid cross chains, the side chains being of sufiicient length to touch the ground when centered over a vehicle wheel resting on the ground, one end of the outer side chain and one end of the inner side chain being provided with enlarged loops or rings and the other end of the inner side chain carrying an extension member of suificient length to first pass through the ring on the inner side chain, then extend. directly across the tire tread to form an additional anti-skid member, and then pass through the ring on the outer side chain, a clamp on the end of such extension member then being secured to a link at or adjacent I: appears in the original patent but forms no part of this italics indicates the additions made by reissue the other end of the outer side chain when the tire chain is drawn into position upon the tire by pulling on such extension member and the end portions of the outer side chain.

A further object of this invention is the provision of an effective tire chain that is simple in construction, inexpensive to manufacture and maintain, and adapted to be fastened upon or removed from a modern automobile wheel quickly by the average driver without the use of tools.

Other objects and advantages will be apparent from the following description, wherein reference is made to the accompanying drawings showing, by way of example, a preferred embodiment of the invention, and wherein Fig. 1 is a perspective view of a vehicle wheel with my improved tire chain centered thereover preparatory to being secured thereupon;

Fig. 2 is an elevational view of the inside face of the wheel, with the inner side chain of my tire chain in annulus form after completion of the first step of securing the tire chain onto the wheel;

Fig. 3 is an elevational view of the outside face of the wheel, after the completion of the second step of securing the tire chain upon the wheel;

Fig. 4 is an elevational View similar to Fig. 3, after the completion of the third and final step of securing the tire chain including my adapters upon the wheel;

Fig. 5 is a plan view of a clamp preferably used in my improved tire chain; and,

Fig. 6 is a side elevation of such clamp.

Referring now to the drawings, the numeral l0 designates a strand of chain herein called the outside chain because it is the one that when positioned on the wheel will be furthest removed from the vehicle. It is also referred to herein as the shorter chain because it is not as long as its companion chain I I, being in fact of lesser length than the circumference of the wheel tire and adapted when in use to be positioned adjacent to the inner periphery of the tire, as best shown in Fig. 4. The terminal link 12 at one end of the shorter chain In is preferably in the form of a loop or ring sufficiently oversized to permit easy passage therethrough of a portion of the companion chain II, as will be hereinafter described. It will be understood that the terminal link I2 may take various shapes provided loop portions of suflicient area are included in their formation. The inside chain l l is adapted to be positioned in use adjacent the inner periphery of the wheel tire between the tire and the body of the vehicle. Chain II is much longer than its companion chain I and longer than the circumference of the tire on which it is used, the extra chain portion being utilized in securing the tire chain on the tire, as hereinafter pointed out. The terminal link l3 on one end of inside chain I l is formed as an enlarged loop or ring, similar to the enlarged terminal link IE on chain l6. the other end of chain ll, however, is provided a ciamp M of a size adapted to readily pass through the loops of terminal links l2 and [3:

The side chains In and II are connected together at intervals by anti-skid cross members i5, formed of chain links or otherlsiiitable u e tive material. Preferably the. anti-skid, cross members l are each secured at its ends to links in side chains I0 and II substantially equidistant from the enlar ed ringed'ends of chain ll and of chain l0, and are provided. in sufilci'ent number to extend at substantially equal distances from each other throughout the entire length of the shorter side chain l 0;

As best shown in Fig. 1, side chain H has a long free portion HA to which no anti' skid members are connected, and this free portion l M is used to secure thetir'e chain'upon a wheel tire, by first extending along the inside of the tire to and passing through the terminal ring I3 of the inside chain [I to complete the an n'ular ositioning of such inside chain beside the tire (Fig; 2), and then passing directly across the tire to and through the adjacent" terminal ring l2 'of the outside chain I'D (Fig. 3), and finally extending along the outer side of the tire to the other end of the outside chain", to a link of which it is secured by its terminal clamp 14 (Fig. 4"). Where it extends across the tire, the free portion H'A" of chain H serves as an additional anti-skid member; substantially parallel with the spaced anti-skid cross members I 5", and the length of the free portion HA is preferably just 'suffi'cient to leave approximately the same amount of slack in its anti-skid cross portion as prevails in the anti-skid cross members [5 when the terminal clamp. M is. engaged so as to complete the desired substantially ann'ular positioning of outside chain It beside the tire. This provides a comparatively loose, easily secured tire chain adapted for quick mounting upon a wheel tire in inclement weather; and which will maintain an increased traction between the tire and road surface as long as desired.

It is preferred to have the inside chain comprised of substantially the same number of links as the 'outsidechain; when both are positioned for use, and eliminate .possible slippage of the free portion HA through terminal linksl2 or l3 to slightly unbalance the annular portions, of the side chains. For this purpose, an additional pair of clamps are carried in the free portion A of the longer .side chain one, as [6, being spaced from the terminal clamp M by an appropriate number of. links so that, when the clamp is is engaged over the terminal ring l2 of outside chain [0. (Fig. 4), such outside chain is comprised of substantially the same number of links as the inside chain 1 i when the third clamp, as ILis engaged over its terminal ring 13. (Fig. 2.5) Thus the clamps 16 and f1? eliminate possibl'e slippage of 'the free portion 11A through terminal links 12 and 13 and in addition assure that the. tire chain remains 'on the tire even thoizgh the free portion 11A which serves as an additional anti-skid cross member becomes broken in use.

To apply the tire chain upon a Wheel tire resting upon the road, the tire chain is substantially centered over the wheel with the free portion H'A of the inside chain resting upon the road aft of the Wheel, and one or more of the antiskid cross members l5 contacting the road in front of. the wheel. (Note Fig. 1). The free portion I IA is then pulled forwardly and threaded through theflterininal ring it of the inside chain, which is simultaneously pulled rearwardly, the pulling being continued until clamp i1 engages over such terminal ring 53, as shown in Fig. 2. This tautens the inner chain H and positions it as a substantial annulus beside the tire. If desired a suitable instrument, such as a hooked rod, may be used to draw ring 13 rearwardly to facilitate positioning of clamp ll therein. The free portion HA is then brought directly under and across the tire, preferably as close to the road as can conveniently be done, and clamp 16' then engaged over the terminaliring l2 of the outside chain it, as shown in Fig 3;. The remaining end portion of extension HA is then pulled rearwardly and the rearward end portion of the outside chain ill swung forwardiy until the terminal clamp 64 engages over a suitable link of the outside chain to complete the outer annulus. (Fig. 4.)
