IMPROVEMENT IN VEHICLE-TIRE TIGHTENERS.

Specification forming part of Letters Patent No. 204,563, dated June 4, 1878; application filed April 27, 1878.

To all whom it may concern:

Be it known that I, GEORGE A. HALL, of Waterford, in the county of Oxford and State of Maine, have invented a new and valuable Improvement in Rim-Supporters and Tire- Ti ghteners; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is arepresentation of an elevation of the wheel, showing the tightener applied. Fig. 2 is a sectional view.

This invention has relation to that class of tire-tighteners which are perm aneutly attached to the wheel 5 and it consists, mainly, in the construction and novel arrangement of the tenon-sleeve, externally threaded from end to end and flush with the spoke at the shoulder of the tenon, upon which it is driven and rigidly secured, the felly-socket perforated for the passage of the tenon and having the side flanges to prevent turning, and the tighteningnut working on the screw-sleeve against the base of the felly-socket, as hereinafter fully shown and described.

In the accompanying drawings, the letterA designates the felly-sections, at the joints B of which the tightener is usually arranged. O designates the tightener, whereof the external appearance is similar to that of a metallic spoke and felly joint connection. This tightener consists of three parts--the felly holder or socket a, having projecting side flanges or lips a for assisting in preventing lateral displacement of the fellies, the screw-sleeve b, and the tightening-nut cmade separate from each other and arranged as follows: The screwsleeve 1) is driven tightly upon the tenon D of the spoke E and against its shoulder 01, so.

designed to work upon the screw-sleeve, and in its usual position may cover the joint between said sleeve and the spokeshoulder.

The felly-socket or holding-plate a is preferably made in the usual form or concave to receive the ends of the felly-sections at their joint, and is provided with a central opening, 6, for the passage of the tenon. The base of the socket or around the margin of the opening 6 is preferably finished flat, as indicated at g, as it is against this portion of the socket.

that the tightening-nut 0 works when it is turned upon the sleeve 1) to move outward in the direction of the felly-joint.

I am well aware thatit is not new to arrange a tightening-nut upon a spoke-tenon to work in connection with a threaded folly-support; also, that it is not new to employ a reduced screwsleeve having an additional shoulder to that of the spoke-tenon, as this necessarily weakens the tenon because of the small size to which it is reduced after forming two shoulders thereon.

I am also aware that a tightening nut has been used in connection with a fellysocket, and a metallic screw-threaded extension of the spoke connected therewith by a coupling; and I do not therefore claim such invention.

What I claim, and desire to secure by Letters Patent, is

In a tire-tightener, the tenon-sleeve b, externally threaded from end to end and flush with the spoke at the shoulder of the tenon, upon which it is driven and rigidly secured the felly-socket a, perforated for the passage of the tenon and having the side flanges a to prevent turning, and the tightening-nut 0, working on the screw-sleeve against the base of the felly-socket, all constructed and arranged as herein shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE A. HALL.
