SPECIZFIQATION forming part of Letters Patent No. 750,600, dated January 19, 1904. Application filed November 28, 1902. Serial No. 133,039- (No model.)

that class of tires known as cushion-tires c. 6., those in which an elastic body or strip is secured in a metallic rim.

The present invention designs to provide an improved tire which is simple and inexpensive of construction and which will be securely held in true longitudinal alinement in the rim.

ith this object in View the invention consists in the several novel features of construc-' tion hereinafter described, illustrated in the accompanying drawings, and more particularly defined by claims at the conclusion hereof.

In the drawings, Figure 1 is a perspective View of a portion of a tire embodying the in- Fig. 2 is a View in horizontal section.

A denotes a metallic rim having the usual flanges, between which a channel is formed wherein an elastic body or strip B will fit and be held.

C and C are retaining-bands in longitudi-- nal bores or openings 6, formed in and extending entirely around the elasticstrip, and these bands secure the strip in the rim-channel.

D denotesa coil of wire embedded in the elastic strip around each of the bores b and retaining-bands D and extended longitudinally through the elastic strip. Each bore is of substantially the same diameter as the retaining wire extending therethrough, and each coil of wire has an inner diameter substantially the same as the bore, so substantially the entire inner surface of the coil will be exposed adjacent the bore. The retainingwire will engage not only that part of the coil between the retaining-wire and rim, but also the sides and outside portions of the coil. In

other words, the coil forms a flexible. compressible metallic lining around the entire bore The longitudinal wire will fit snugly in the bore and spect to the rim. The coil will effectively prevent cutting or wear of the strip by the longitudinal wire, resulting from vertical and lateral pressure to which the elastic strip is subjected while in use.

In manufacturing the tires the elastic strip is sometimes molded in long straight strips sufficient in length to encircle a rim. Cores of substantially the same diameter as the retaining-wires are within the mold and form the longitudinal bores, and the coils are placed around these cores. The coils having substantially the same inner diameter as the diameter of the bore and fitting snugly around the cores are truly-alined in the elastic strip, and therefore form a true metallic-lined bore for the retaining-wire. When the elastic strip is formed in a circular mold, the retaining-wires are endless, and the elastic strip is formed with the wire or wires therein.

An important resultant advantage is that all lateral irregularities in the bore and strip are avoided, so the elastic strip will fit truly and accurately in the rim-channel. advantage is that the coil or metallic lining being but little'greater diameter than. the retaining-wires will not lessen the resiliency of the tire." I

In applying an elastic strip to the rim it is customary to compress the elastic strip so when laid into a circular rim it will possess the desired density. the coils will permit the desired flexure and compression and prevent the cutting either laterally or Vertically by the retaining-wires.

Manifestly tires made as hereinbefore set forth can be economically produced, are durable because cutting of the elastic body in either direction is prevented by the snugly- During such operation A further a coil of Wire embedded in said strip 01' body, and extending longitudinally through said strip and around each of said bores or openings, to form a compressible metallic lining for each bore, and having an inner diameter substantially the same as the diameter of the bore, and a retaining-Wire fitting snugly Within each bore and coil.
