WHEEL.

SPECIFICATION forming part of'Letters latent N o. 705,567, dated July 29, 1902. Application filed May 11, 1901. serial No. 59,841. (Np model.)

Beitknown that LELLswoETH tTimm/lans, a citizen of the United States, residing at Aspen, inthe county of Pitkin and State of Colorado, have invented a new and useful Wheel, of which the following is a specification.

This invention relates generally to wheels, and more particularly `to the peculiar construction of the spokes and the manner of attaching the same to the hub, the object of the invention being to provide a highly-elastic` wheel which shall at the same time be exceed ingly strong and durable.

With these objects in view the invention consists, essentially, in providing a hub with flanged collars at each end and to which the ends of the spokes are attached through the' medium of iianged nipples, said nipples resting upon springs interposed between their flanges and the flanged collars of the hub.

The invention consists also in the peculiarhub. Fig. 3 is a detailview of the tapering and anged nipple. Fig. 4 is a sectional elevation showing the manner of connecting the central portion of the spokes to the wheelrim or felly. Fig. 5 is a detail view illustrating.

the threaded sleeve.` Fig. 6 is a sectional view of the spoke connection. Fig. 7'is `a slightly-modified form of wheel-rirn. Fig. 8 is a view showing the interior of the hub and illustrating a slightly-modified arrangement of the springs.v Fig: 9 is a detail view showing a still further modification, and Fig. 10 is aplan view illustrating the construction of the springs shown in Fig. 9.

In carrying out my invention Iemploy a sleeve-hub A, having annular vertical flanged collars, from which project annular horizontal collars B, formed adjacent to each end, the inner surface of the horizontal fianges beingbeveled and formed with tapered openings to receivejapered internally-threaded nipples throughwhich the ends of the spokes are attached, said spokes being bent centrally to form diverging spokes, their central portion being connected to therm of the felly D, as hereinafter described. The ends of the spokes are threaded, as shown at C', and pass through the flanged collars B within the internally-threaded nipples which are secured .upon the end C"fron1 the interior of the hub said tapering sleeves or nipples having flanges or collars E', adapted to bear upon shown at F2, said springs F:2 being bow-shaped and perforated at their ends, as shown at F3, and through which the sleeves or nipples pass, the anges er collars bearing upon the ends of the springs, the central or bow portions of said springs bearing against the inner faces of the hub-collars. r The ends and the central portion off the spokes are swaged or thickened, as shown, in order to give greater strength. The central portion of the spoke is passed through the eye Gf of a sleeve G, which sleeve is adapted to it into a socket produced in the rim or fellyand secured therein by means of Ia screw H, passing through the rim or felly from the outside and entering the threaded socketG?, produced in the sleeve G.

In Fig. 4I have illustrated a'pfheel'having a flat tire, While in Fig.` 6I have Aillustrated a construction adapted' to receive a rubbertire. In Fig. 1I have shown a rubbertirearranged in connection with the wheel-"rim'illustrated in Fig. 7, formed of metal and essentially T- shaped in cross-section, with ilanges for retaining the rubber tire, the inner iiange of said rim being reinforced at definite points, as shown at I, and through which the spoke passes, said rim being reinforced to provide a firmer bearing and also increase the strength of the tire at these points.

IOO

The outer`ends of the annular flanged collars B are closed by means of annular horizontal and vertical caps, as shown in Fig. l, and when in place produce a uniform outer surface on both sides of the flanged collar.

It will thus be seen that I provide an exceedingly simple and efficient construction of spring-wheel which shall have a maximum amount of elasticity and at the same time be exceedingly strong and durable.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a Wheel, the combination With a hub having flanged collars, of spokes having their ends extending through the said flanged collars, the tapering sleeves or nipples having flanges of collars, secured upon the ends ot the spokes, and springs interposed between the flanged collars of the hub and the flanges or collars of the sleeves or nipples, substantially as set forth.

2. In a Wheel, the combination with a hub having llanged collars, of the spokes having threaded ends passing through the said flanged collars, the tapering sleeves or nipples having langes or collars, screwed upon the ends of the spokes and extending through the collar of the hub, the springs arranged between the hub-collar and the llanges or collars upon the sleeves or nipples, said sleeves or nipples passing through the said spring substantially as described.

3. In a Wheel, the combination with a rim, of an internally-threaded sleeve arranged in said rim and having an eye at its end, a screw passing through the rim from the outside and arranged in the threaded sleeve, and a U- shaped spoke passing through the eye of said sleeve, substantially as described.
