Application nied eceinber 21, 1918. Serial No. 2673.814.

To all whomfz' concern.' y Beit known that I, Simmer. J. S'rrnv,I a citizen of the United States, and a resldent of Greenwood, inthe county of Leflore and State of Mississippi, have invented a new and Improved Attachment for Pneumatic Tires, of which the following is a full, clear, -and eXact description.

My invention relates to a non-skid, puncture-proof protector adapted to be applied to a pneumatic tire, and the invention has for an object to provide a protector composed of annular series of plates having nonskid elements and hinged together, certain of the hinges being formed to present end members adapted for connection with the elements employed for fastening the protector to a wheel.v Y

The above and other objects as will appear are attained by the novel construction and arrangement of parts hereinafter particularly described.

Reference is to be had to the accompany ing drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a plan view of a portion of a device embodying my invention;

Fig. 2 is a longitudinal section on the line 2-Q, Fig. 1;

- Fig. 3 is an enlarged section on the line 3 3, Fig. 1; K l

Fig. et shows'in side elevation a portion of a wheel with a portion of my protector in place;

Fig. 5 is a detail showing in cross section a portion of the wheel rim with the means of securing the fastening elements to the rim.

In carrying out my invention in practice, a series of plates 10 are provided adapted to lic on the out-er surface of a tire A as in Fig. 4:. To provide non-skid members the' several plates in practice are provided with punched up protuberances 11 and also, the side edges of the plates are provided with out-turned flanges 12 which in addition to contributing to the non-skid character of Vthe protector Serve to strengthen the plates.

The plates are hingedly connected to one another. Alternate hinges may be of known form involving aldining knuckles 18 and a hinge' pin 14 passing therethrough. Others et the hinges, preferably alternate ones, conE lsist of tubular yedge portions 15 on adjacent transverse edges of thev plates, the adjacent tubular/members lying in close relation and parallel. Through tubular edges 15 of a pair extend double pins 16 which are given a form to adapt them to connect with fastening members adapted to be fastened to the wheel on ,which the protector is employed. Each pin 16 is formed of a continuous length of rod or. wire returned on itself,

thereby presenting a loop 17 at one end of the double lpin projecting beyond the side e Oes of the plates 10. At the opposite end the terminals of the double pin 16 are return bent in hooked form as at 18 disposed beyond the adjacent-side edges of the plates.

The ends of the double pin 16 presenting Y respectively a. loop 17 and hooked terminals 18 are utilized for connecting with the protector the fastener elements which may consist, as indicated, of lengths of chain 19. At'onc side of the protector the ring 20 of a fastener element 19 passes through the loop 17 while at the opposite side the ring embraces the double pin 17 and is held aga-inst displacement by the return hooked ends 18.

The elements 19 lat the inner ends may be made fast to the wheel inV any approved manner; as here shown each element 19 eX- tends to the interior of the rim B of the wheel and is secured by a. thumb screw 21 in said rim and adapt-ed to be given a quarter turn. With the head of the thumb screw parallell with the links, the inner end link of the element 19 may be passed over said head after which the screw is given a quarter turn to dispose the head of the screw transverse to the chain link as indicated in dotted lines in Fig. 5. By providing pins 16 of a form to connect with the fastening j elements, the use of separate means on the protector for connecting said elements is avoided. Y l

I would sta-te in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated since manifestly the same can be considerably varied without departure from the Spirit of the invention as defined in the appended claims.k

I-Iaving thus described my invention, I

claim as new, and desire to secure by Letters Patent: Y l

1. A tire protector including a series of protector elements,` hinge means uniting said elements, Said hinge ineens zit certa in of the hinge connections comprising tubular edges on adjacent elements and parallel with each other, and double pins therein, said pins being united at one end by an integral loop, the terminale or' seid pins at the opposite ends thereof being returned in hooked forni in opposite directions; together With 'tustener elementsY adapted to be secured to :t Wheel, and ringe` on said elements and connected with said pins, those rings at one eide of the protector passing through the loops of the pins, and those rings at the opposite side or' the lprotector embracing seid pins inward oit the returned termina-ls thereof.

2. A tire protector including` n, series of protector sections, and double hinge pins linking adjacent protector `Sections together` said pine presenting transversely disposed parallel ineinhers hinged to the respective ends of the `adjacent sections; together with feet-ener ineens to secure the protector on :iy Wheel7 the ende or said double pins having members secured to said fastener Ineens.
