BESILIENT WHEEL.

Specification of Letters Patent.

Patented Sept; 18. 1917.

Application filed May 19, 1917. Serial No. 169,733.

To all whom it may concern.

Be it known that I, EDWARD I. Mon/En, a citizen of the United States, residing at Cresson, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Resilient heels, of which the following is a specification, reference being bad to the acconr panying drawings.

This invention relates to certain improve -1ncnts Ill resilient wheels and 1t is an object of the invention to provide a device of this general character for novel and improved means whereby the shocks and jars incidental to travel are substantially entirely absorbed.

It is also an object of the invention to provide a device of this general character wherein the wheel is efl'eetivciy brace-d to overcome lateral strain. 7

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved resilicnt wheel whereby certain important advantages are attained and the device is rendered simpler. less expensive and otherwise more convenient; and advantageous for use, all. as will be hereinafter more fully set forth.

The novel features oi rhiinvrutirai will hereinafter be definitely claimed.

In ordei' that my invention may be the better understood. T will now proceed to describe the same with reference to the accom;

panying drawings, whercin-- Figure 1 is a fragmentary view in elevation of a wheel mnstrupted in accordance with an embodiment of mv invention;

Fig. 2 is an enlarged fragineutary view partly in elevation and partly in section illustrating a pair of bracing members as herein embodied: and

Fig. 3 is an enlarged fragmentary view partly in section and partly in elevation illustrating in detail a? connection of an outer end of a spoke with the felly of the wheel as herein disclosed.

As disclosed in the accompanying drawings H denotes the hub of my improved. Wheel provided with transversely spaced annular flanges 1. Extending between the flanges 1 are the inner end portions of the spokes S which are pivotally held between said flanges 1 through the medium of the pintles or bolts 2. Each of the spokes S comprises two sections 3 and 4. The section 3 has its outer portion tubular to snugly receive the inner end portion of the section 4. The outer end portion of the section 4 extends within a suitable opening or recess 5 produced in the annular member 6. The outer end portion of the member 4 is also pivotally held to the member (3 through the medium of the bolt or pintle 7. The outer end portion of the section 4: has threaded thereupon the nuts 8 and interposed between the inner not 8 and the outer end of the coacting section 3 is an ex'pansibic member 9 herein disclosed as a coiled spring encircling the inner end portion of the section 4 and which serves to constantly urge the section 4 outwardly. It is to be understood that the nuts 8 may be adjusted longitudinally of the section -lto regulate the tension of the cxpansiblc member or spring 9 in accordance with the Itqllil'fillltfltS of practice. Intermediate each. pair of adjacent spokes S is arranged a pair of bracing members B. Each of the members comprises two flat sections 10 having their adjacent end portions in overlying relation and pivotally connected as indicated at 11. The op osite end portion of the inner section 10 0 each of the members ll is pivotally engaged with ::v pintlr or a bolt 12 dispmed througl'i the peripheral portions of the flanges 1. It is preferred that the portion of each of the pintlcs or bolts '12 intermediate the flanges 1 be surrounded by a spacingslceve 14 so that strength of the hub ll is materially increased. .lhe outer end portion of the other section 10 of each of mmnbcrs B is pivotally engaged with, the bolt or pintle 15 disposed through the annular member 6.

The member 6 lits snugly within the rim or Folly it and is held in applied position in any desired manner but preferably through the medium oi the bolls if; or the like. it is also lo he noted from the disclosure in Fig. 2 that the member 6 is of a width less than the space between. the flanges 1 so that the members B of each. pa'ir are disposed in- Wardly in divergence so that the wheel structure is effectively braced against lateral strain and to maintain the rim ll in proper position relative to the hub ll. 'lo 'l'urthcr facilitate the function of the members it I find it of advantage to apply to the opposite end portions of each of the bolts 12 inter mediate the ad acent end portions of the members B and the flanges 1 the washers 18. The outer faces of the. washers 18 are convex as part'cularly illustrated in Fig. 2 of the accom nying drawings. This formation of the washers 18 is of material advantage as it prevents such bending of the inner end portions of the brace members B upon relative lateral movement of the rim R and the hub H flexing the members B in a manner which would ultimately result in the fracture of the members B. It is to be understood that any form of tire may be applied to the rim or felly R as the requirements of practice may dictate but it is preferred that a solid tire be employed so that the possibility of punctures, blowouts, or the like are eliminated.

From the foregoing description, it is thought to be obvious that a resilient wheel constructed in accordance with my invention is of an extremely simple and comparatively ine'cpensive nature and is particularly well adapted for use by reason 0 the convenience and facility with which it may be assembled, and it will also be obvious that my in vention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the recise arrangement and formation of t e several parts herein shown in carrying out my invention in claimed.

I claim: A wheel structure comprising, in combination, a hub a felly, spokes interposed between the felly and the hub and ivotally engaged therewith, each of said s 0 es comprlsing telescopically engaged sections, 40 means co-acting with the sections of each of the spokes for constantl impartin separating movement thereto, brace mem ers positioned between adjacent pairs of spokes, each of said brace members comprising pivotally connected sections, said brace members being arranged in pairs and disposed inwardly in divergence, the outer end portions of the brace members being pivotally engaged with practice, except as hereinafter the felly, bolts disposed throu the hub and extendin beyond opposite si es thereof, the inner en s of the brace members being pivotally engaged With' the bolts, and washers arranged upon the bolts and positioned in termediate the brace members and the hub, the faces of the washers adjacent the brace members being convex.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.

EDWARD I. MOWER.
