RUSSELL JENNINGS, OF SEDALIA, MISSOURI.

Tl RE-TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 369,719, dated September 13, 1887.

Application filed February 11, 1887. Serial No. 227,302. (No model.)

To aZZ whom, it may concern.-

Be it known that I, RUssELL JENNINGS, a citizen of the United States, residing at Sedalia, in the county of Pettis and State of Missouri, have invented certain new and useful Improvements in Tire-Tighteners; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of tiretighteners which comprise a threaded bar having an adjustable clamp and nut adapted to be adjusted by means of a suitable wrench to bring the clamp to bear against the felly, whereby the sections of the latter are separated from each other and from the spoke to permit the insertion of wedges. As heretofore constructed most tire-tighteners of this class have been open to the objection that they are not adapted for use upon wheels whose spokes are very close together, and to the further objection that during the adjustment of the device the foot-rest, being ordinarily an integral part of the threaded bar, will turn laterally and bear against the sides of the spokes at the hub and bruise and damage the spokes.

The primary object of my invention is to provide a device adapted for use upon wheels of various sizes and construction; and to this end my invention consists in an improved footrest separate from the threaded bar and adapted to fit between the spokes of different sizes and styles of wheels.

My invention further consists in certain improvements in the construction, arrangement, and operation of parts, substantially as will be hereinafter fully set forth.

In the drawings, Figure 1 is a side elevation illustrating the application of my improved tire-tightener. Fig. 2 is a side view of the tire-tightener. Fig. 3 is a longitudinal sectional view. Fig. 4 is a detail perspective view of the foot-rest. Fig. 5 is a detail bottom view of the foot-rest. .Fig. 6 is a detail perspective view of the cap-piece.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, Adesignates the threaded bar, upon which is mounted a nut, 13, supporting a cylindrical tube, 0.

This

tube is mounted upon the top end of the threaded bar and has its lower edge resting upon the nut, whereby when the nut is ad justed the tube is elevated to bring the cap piece D against the under side of the felly.

The cap-piece D is loosely set or fitted upon the end of the tubular section, and for this purpose it is provided in its under side with an annular groove, (1, to receive the corresponding end, b, of the tubular section. top surface of the cap-piece is grooved or concaved from the center, as illustrated at d d. By this improved construction, and by mounting the cap-piece loosely upon the tubular sec tion, the cap-piece more readily adapts itself to the inner face of the felly, and if a bolt projects through the latter, as frequently occurs at the point where the cap-piece is applied, the cap-piece will assume an inclined position relative to the tubular section, as illustrated in dotted lines, Fig. 3, one end being adapted to rest on the bolt and the other setting up against the inner face of the felly.

E designates the foot-rest, which is separate from the threaded bar and formed with a longitudinal groove, e, in its top surface, this groove being concaved or approximately V- shaped in cross-section. The sides of the footrest are inclined to adapt them to fit between the spokes at the hub, and at intervals shoulders f are formed and extend around the sides and bottom of the foot-rest, thus dividing the latter into sections F of varying diameter. Some of these sections F are provided with a squaredbottom edge, as shown at f, while others are provided with acurved bottom edge, f, and a series of graduated members, as shown, may be provided to distinguish the different The sections. By this improved construction of foot-rest, embodying the sections of different sizes and construction, my improved tiretightener is adapted for use upon wheels of different sizes and construction, the foot-rest being set between the spokes until the section corresponding to the space between the spokes comes in position. The nut may then be operated and the felly and spokes tightened without marring or bruising the ends of the spokes at the hub.

The threaded bar is provided with an enlarged and flattened lower end, A, having an approximately V-shaped or convex bottom edge, a, corresponding to and received by the groove in the top of the foot-rest.

In using my improved tire-tightener I prefer to use a vulcanized paper washer to take foot-rest having a longitudinal groove in its top surface, a threaded bar separate from the foot-rest and having a V-shaped or convex end corresponding to and received by said groove, a nut working upon the bar, a tubular section supported upon the nut, and a cap piece loosely mounted upon the tubular section and adapted to assume an inclined position in relation thereto, substantially as set forth. I

2. In a tire-tightener, the combination of a foot-rest having a longitudinal V-shaped or concave groove in its top surface and formed with inclined sides and with shoulders dividing the foot-rest into sections of different diameter, a threaded bar having its lower end V-shaped or convex corresponding to and received by said groove, a nut working upon the bar, a tubular section supported bythe nut,

and a separate cap-piece having an annular groove receiving the top end of the tubular section, substantially as set forth.

3. In a tire-tightener, the combination, with a threaded bar having a V-shaped or convex lower end, of a separate foot-rest having a longitudinal V-shaped or concave groove in its top surface and comprising sections of different diameter, substantially as set forth.

4. In a tire-tightener, the combination, with a threaded bar having an enlarged or flattened lower end formed with a V-shaped or convex edge, of a separate foot-rest having a longitudinal V-shaped or concave groove in its top surface and formed with inclined sides divided by shoulders into sections of different diameter, substantially as set forth.

5. The herein-described improved foot'rest, approximately V-shaped in cross section and formed with a longitudinal groove in its top surface, the inclined sides being provided at intervals with shoulders dividing the rest into sections of different diameter, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

RUSSELL JENNINGS.
