STEPHEN ANDREWS, OF NEV YORK, N. Y.

ARIVIOR FOR TIRES.

Application filed January 3, 1921.

To all whom it may concern:

Be it known that I, STEPHEN Annnnws, a citizen of the United States, residing at New York, in the county of New York, and State of New York, have invented new and useful Improvements in Armors for Tires, of which the following is a specification.

This invention relates to protectors or armors for pneumatic tires.

Some of the objects of the present invention are: to constitute a shell or carcass of sections of comparatively greater invulnerability than the carcass of the ordinary shoe forming a part of an ordinary pneumatic tire, for the protection of the shoe; to form the shell or armor of sections which are connected together end to end for the relative yielding action of the said sections; to yieldingly connect the said sections together in such a manner that by virtue of their construction, the sections will afford a substantially smooth traction surface. l/Vith these and other objects in view the invention resides in the particular construction and the relative arrangement of parts hereinafter more fully described and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation illustrating the application of the armor of the present invention to a pneumatic tire.

Figure 2 is a fragmentary perspective view showing the disposition of the bands which connect the sections from which the armor is formed.

Referring now more particularly to the drawing for details, it will be manifest that, the armor of the present invention includes a multiplicity of sections 10 each of which is identical as to construction in that each has formed therein ways or openings 11 and 12. The ways or openings extend from one end to the other in each section 10. The opening 11 extends through the tread portion, whereas the openings 12 of each section extend through the side portions thereof. When the sections 10 are arranged end to end. forthe completion of the armor, the openings of the different sections register with each other. The sections 10 are connected together by the employment of a flat band 13 of stout and elastic material, and cross-sectionally round bands 14 of stout and elastic material. The band 13 is passed through the opening 11 of each section 10 Serial No. 434,567.

which goes to make up the armor, and the bands 14 are passed through the openings 12 of each of the said sections. When the prescribed number of sections 10 have been c011- nected together, the opposite ends of the bands 13 and 14: are vulcanized, to make continuous elastic connecting means for the allowance of relative movement of the sections with respect to each other. When arranged over the shoe of a pneumatic tire the sections may yield with the tire to any irregularities or obstructions of the road surface. Through the longitudinal axis of the tread portion, each section is similar in shape and thickness, thus when the sections are connected together as explained, the periphery of the armor will be substantially smooth irrespective of the anti-skidding surface that each of the sections may have.

The sections 10 are to be moulded or otherwise formed of selected material which will afford the qualities of resiliency and durability.

The elasticity of the bands 13 and 1% permits the armor to be readily mounted and demounted.

The employment of non-metallic means for connecting the sections 10 together, eliminates heating of the armor. The fact that the armor is not attached in any manner to the tire it protects, or to the wheel which is equipped with the tire more than compensates the difference of strength of metal over rubber, the material used for the bands 18 and 14:. There is very little strain on the bands, aside from the strain due to irregularities of the road surface.

lVhat is claimed is;

1. An armor for pneumatic tires comprising interconnected sections disposed normally end to end in contiguous relation, and elastic bands extending through the sections permitting relative movement of the sections with respect to each other.

2. An armor for pneumatic tires comprising resilient sections, and continuous elastic bands extending through said sections, and connecting said sections together, the said sections being disposed end to end contiguous each other as their normal relation.

In testimony whereof I hereby affix my signature.

STEPHEN ANDREW S.
