Patent @rrrca ELASTlC TIRE.

SPECIFICATION forming part of Letters Patent No. 7&7337, dated December 15, 1903.

Application filed June 19, 1903. Serial No. 162,2A5. (No model.)

To all whom it may concern:

Be it known that I, WILHELM WHEATON strong durable tire of maximum resiliency with a minimum of weight, and the construction to be hereinafter described has been found to attain this purpose in a highly efficient and satisfactory manner.

The invention comprises the construction and arrangementof component parts and the details of construction to be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings,which illustrate one embodi ment of my invention, Figure 1 shows in cross-section the completely-assembled tire attached to the telly of a wheel. Fig. 2 isadetail view of one fabric from which the resilient rings to be described are made, and Fig. 3 is a detail view of a modified construction of fabric.

The tire includes generally an inclosing casing of cloth or similar fabric, a plurality of hollow resilient rings incased therein formed of wire fabric, a distributing or equalizing band interposed between said rings, a compressor-band, and means for securing the inclosing casing to the felly of a wheel. In the accompanying drawings the inclosing casing is designated by the letter (L, and the wheel-felly, to which it is secured along each longitudinal edge, by the letter 5.

lncased within the annular chamber, provided by the periphery of the Wheel-felly and the casing a, a plurality of resilient tubular rings 0 d e are located, the same being formed of a suitable wire fabric. In the present exemplification' of my invention three of these rings are employed, the rings 0 d being arranged side by side contiguous to the periphcry of the folly and the ring 6 being located centrally of the rings 0 d and to .the outside of the same, contiguous to the central part or tread portion of the casing a.

In use the ring e is designed to first receive the pressure upon the tread of the tire and transmit the same to the rings 0 d, and to aid in the distribution of the pressure an equalizing-bandfof thin metal having some elasticity, is preferably interposed between said ring 6 and the rings 0 d. The bandfis provided with flanged longitudinal edges to embrace the outer peripheral portions of the rings 0 cl or longitudinal edge pockets toaccommodate the latter, while the central portion of the band is provided with a slight annular concavity to better center the ring 6, which bears thereupon.

The longitudinal edges of the casing 01- are secured to the side of the felly b in any suitable manner, preferably by rings t' is, clamped in place by a series of bolts n, arranged at suitable distances apart around the wheel.

As will be appreciated, when the tire is assembled the casing a will not be suiificiently taut to hold the parts incased therein firmly in position, and to take up any looseness therein and place the parts inclosed by the same under slight compression a tighteningband 0 is preferably provided. The latter band, as shown, is interposed between the periphery of the felly Z) and the rings 0 cl, providing a bearing-surface for the latter. This band is radially expansible under the pressure of screws 19, adjustable in socket-plates fitted in the felly b, which screws are surmounted at their outer ends by arcuate plates, which bear upon the inner surface of the band 0.

To increase the resiliency of the rings 0 d, tubular resilient rings 9 it may be placed within the same to bear upon the outer portions of the inner peripheries thereof.

As before premised, the rings 0 d e are formed from a suitable wire fabric. This fabric consists of a plurality of flat coils formed from light wire, which coils are suitably woven together to form a flat strip, and the latter is then coiled into tubular form and the abutting or contiguous edges woven or joined together. As will be noted from Fig.

3, the fabric includes a plurality of strands 1', each consisting of a central coiled strand s, from the opposite sides of which the flat loops extend and about which the portions of the strands forming said loops are wrapped. The complete fabric strip is formed by arranging a plurality of strands r side by side, with the contiguous loops tthereof interlocked or arranged in alinement and held together by a strandu of light coiled wire, which is passed through the channel provided by the interlocked portions of said loops. To form the ring from the flat strip thus provided, said strip is coiled and the loops t of the contiguous longitudinal edges interlocked and held in place by coiled strands in a manner similar to that employed for joining the strands 'r to one another.

The construction and operation of my in-' vention will be readily understood upon reference to the foregoingdescription and accompanying drawings, and it will be appreciated that the parts and combinations recited may" be varied within a wide range without departing from the spirit and scope thereof.

Having thus described my invention, what is claimed as new, and desired to be secured by Letters Patent, is

l. The combination with the folly of a wheel and a fabric casing secured thereto and forming therewith an annular chamber, of a pair of independent resilient rings arranged side by side in said chamber contiguous to the periphery of the felly, a third resilient ring disposed centrally of and to the outside of the first two rings, and a distributing-band independent of the rings arranged between the third ring and the other two, substantially as described.

2. The combination with the telly of a wheel and a fabric casing secured thereto and forming therewith an annular chamber, of a pair of independent resilient rings arranged side by side in said chamber contiguous to the periphery of the felly, a third resilient ring disposed centrally of and to the outside of the first two rings, and a distributing-band independent of the rings arranged between the third ring and the other two, said band having longitudinal edge flanges embracing the upper outer sides of the first two rings substantially as described.

3. The combination with the folly of a wheel and a fabric casing secured thereto and forming therewith an annular chamber, of a pair of independent resilient rings arranged side -means therefor comprising a screw threaded in a socket in the telly carrying a bearinghead at the outer end of the same, substantially as described.

4.. As a part of a tire, a resilient ring comprising a strip of fabric formed of a plurality of strands '1", each strand 1' comprising a central strand 3 of light coiled wire, fiat loops of light wire 25 projecting from opposite sides of the latter with the strand forming said loops wrapped about the strand .5, said strands 7' being arranged side by side and the contiguous loops t thereof joined together to provide the complete fabric strip and the latter strip being coiled, and the longitudinal contiguous marginal edges joined together, substantially as described.

5. As a part of a tire, a resilient ring comprising a strip of fabric formed of a plurality of strands 0", each strand 7' comprising a central strand 8 of light coiled wire, flat loopsof light wire 25 projecting from opposite sides of the latter with the strands forming said loops wrapped about the strand 8, said strands 7' being arranged side by side, and the contiguous loops tthereof interlocked, coiled strands of light wire passing through the interlocked portions of the loops to join the strips r to one another to form the complete fabric strip and said strip being coiled and the contiguous longitudinal marginal edges interlocked and coiled strands for joining said edges together, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
