RICHARD MULHOLLAND, OF DUNKIRK, NEW YORK.

RUBBER-TIRED WHEEL.

SPECIFICATION forming part of Letters Patent No. 784,8? 5, dated March 14, 1905.

Application filed November 17, 1904;. Serial No. 233,103.

To all whom, it may concern:

Be it known that I, RICHARD MULHoLLAND,

, a citizen of the United States, residing atDunkirk, in the county of Chautauqua and State of New York, have invented certainnew and useful Improvements in Rubber-Tired WVheels,of'

tic-tired wheel for vehicles and the like, and

particularly to the construction and arrangement of the fastening-band and the manner of securing the same to the wheel.

The principal objects of the invention are to simplify and cheapen and also strengthen the construction by reducing the number of parts required and to lengthen the life of the tire to the highest degree by securely fastening the same to the wheel against longitudinal movement or creeping.

The invention also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the preferred adaptations thereof shown in the accompanying drawings, in which Figure 1 represents a side elevation of my improved wheel with a vertical central longitudinal section through the felly, channelrim, and tire to illustrate the interior .connection. Fig. 2 is an enlarged transverse radial section on line a a, Fig. 1. Fig. 3 is an enlarged transverse radial section on line 6 b, Fig. 1. Fig. 1 is a fragmentary enlarged longitudinal radial section on line c, Fig. 2. Fig. 5 is a fragmentary enlarged longitudinal radial section on line (Z (Z, Fig. 3. Fig. 6 is an enlarged fragmentary longitudinal section through the tire on line 0 c, Fig. 2. Fig. 7 is an enlarged fragmentary longitudinal section through the tire on line ff, Fig. 3. Fig. 8 is a detached bottom view of a fragment of the parallel tire-bands, their fastening-plates, and the locking-bolt. Fig. 9 is a section on line g g, Fig. 8. Fig. 10 is adetached bottom view of fragments of the tire-band. Figs. 11, 12, and 13 are detached top plan, side, and bottom views of the fastening-plate. Fig. 14 is a section through the plate on line 72 h, Fig. 12. Fig. 15 is an enlarged detached View of one of the bolts for securing the channel-rim to the felly. Fig. 16 is a transverse section through the tire, rim, and folly of another form of wheel on line d, Fig. 17. Fig. 17 is a longitudinal section on line jj, Fig. 16.

In referring in detail to the adaptations of the invention shown in the accompanying drawings like numerals designate like parts.

The wheel is preferably composed of a'felly 1, a channeled annular rim 2, superimposed on said felly, a tire 3, surrounding and superimposed on said rim, a hub 4, and a series of spokes 5, radiating from and connecting the hub 4 t0 the felly 1.

The tire is preferably of the circular form in cross-section shown in Figs. 2 andv 3, although it may be made in any other suitable shape, if desired, and while it may be in one piece sufficiently long to extend entirely around thorim it is preferably constructed in a plurality of parts, usually two half-sections.

The circular form of tire shown is provided with a central longitudinal opening 6 to provide an interior dead-air space, and thereby render it more elastic, and one or more channeled retaining-bands 7 are passed longitudinally through the tire below said opening 6. In one of the adaptations shown two of these retaining-bands 7 are employed, each of which is located slightly below and to one side of the central opening 6. The two retaining bands 7 in this adaptation extend parallel to each other entirely around the wheel and on the same horizontal plane.

here the tire is constructed in a plurality of parts, the retaining band may also be formed in a like number of parts, which are connected at their ends by an elongated plate or plates 8, which are curved to correspond to the curvature of the retaining-band. This plate 8 is provided on one of its faces with a series of projections or rivet-points 9 and on its opposite face with a series of tapering projections 10, which embed themselves in the tire to prevent longitudinal movement when the parts are in assembled position on a wheel.

The rivet-points 9 and tire-retaining projections 10 are cast or formed integral with the plate 8 to absolutely prevent any separation of parts in an assembled wheel.

IOG

The tire-retai ning projections 10 are tapered on two opposite sides only to provide a \I- shape surface in a transverse direction and a comparatively broad and blunt surface in a longitudinal direction, as shown in Figs. 12 and 13. The purpose of this is to provide a projection which will easily embed itself in the tire-surface and at the same time present a sufficiently broad surface against longitudinal movement to prevent the cutting or slitting of the tire by the projection.

The double or paired retaining-bands are fastened to the folly and rim of the wheel at the junction or junctions of the tire ends by a bolt or bolts 11, which have heads 12 sufliciently broad to extend over both of the retaining-bands, (see Fig. 2,) the shank of the bolt extending inwardly between the retaining-bands and passing through the rim and folly and having a scre\ 'threaded projecting outer end, upon which a lock-nut 13 is fitted.

After the tire is secured to the wheel a series of lag-screws 1 1 are fitted through the folly and rim with their ends projecting or embedded in the tire-surface to prevent creeping, as shown in Fig. 3.

The rim is fastened to the folly by a series of bolts 15, arranged at suitable intervals around the wheel. These bolts 15 are preferably formed as shown in Fig. 15, being provided with a tapering head, which fits in a countersunk opening in the rim, so that the bolt-head is set flush with the rim.

In the adaptation shown in Figs. 16 and 17 but one retaining-band 7 is used, which is located vertically below the central opening 6 in the tire. The ends of this band are fastened together by an elongated plate 16, similar to the plate 8, heretofore described. This plate has rivet projections 17 and tire projections 18, which are similar to the projections 9 and 10 before described, and is also provided with a shank 19, which takes the place of the bolt 11, used in the other construction described. This shank 19 passes through the rim and folly and has a projecting screwthreaded end upon which a lock-nut 20 is fitted.

The wheel parts are preferably assembled in the following manner: The rim 2 is fitted upon the folly 1 and fastened in place by the bolts 15. The tire, which is of greater length than the distance around the CIICLlll'lfGl'G-HCG of the rim, so that the tire will be longitudinally compressed when on the wheel, is fitted with one or more channeled retaining-bands and placed around the wheel. The tire ends are now compressed sufiiciently longitudinally to expose the ends of the retaining-bands and the lock-plates 8 are inserted in the channels or grooves in the retaining-bands with the rivet projections 9 extending through openings 21 (shown in Fig. 10) in the channeled bands. The rivet-heads are flattened to firmly secure the plates to the bands, as shown in Fig. 9.

In the adaptation shown in Figs. 1 to 8, inclusive, the bolts 11 are arranged in place with their heads upon the two bands and their shanks extending through the rim and felly, and the ends of the tire are released and then drawn together into abutting position in any of the well-known ways. The lock-nuts 13 on the bolts 11 are now screwed tight, drawing the tire firmly into position on the rim.

In the adaptation shown in Figs. 16 and 17 the ends of the tire are released after the plate 16 is riveted in place, and the lock-nuts 20 are screwed upon the shank 19.

I claim as my invention 1. In a wheel of the class described, a felly, a rim on said felly, a tire on said rim, one or more retaining-bands extendingthrough said tire and a plate for locking the ends of said bands having a series of tire-retaining projections which are tapered to present a sharpened surface transversely and a comparatively broad and blunt surface longitudinally for the purposes set forth.
