EZRA P. ROSS, OF LEBANON, PENNSYLVANIA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO J. FRANK BEHNEY, OF SAME PLACE.

TIRE-TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 231,102, dated August 10, 1880.

Application filed June 7, 1880.

To all whom it may concern:

Be it known that I, EZRA P. Ross, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Tire-Tighteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to IO which itappertains to make and use the same,

reference bein g had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in that class of devices for adjusting the felly of a wheel upon the spokes of the same, consisting of a clamp by which it may be secured to the spokes and a screw-threaded 2o shaft provided with a fixed collar operating a movable dog bearing against the inside of the folly to distend the same.

The object of the presentinvention is to provide an improved means of operating the screw- 2 5 threaded shaft and for securing the clamp to the spokes, whereby all detached parts are dispensed with and a compact and convenient device is made in which the parts are all connected permanently together in position ready 0 for immediate use. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of my improved device; Fig. 2, a front elevation 3 5 thereof, and Fig. 3 a detached view of the clamp.

The letter A indicates a clamp formed in two parts, a b,hinged together at B on one side. The said clamp on the opposite side is pro- 0 vided with two lugs, d e, on each part, and between the lugs 61 is pivoted thesquare head of a screw-threaded pin, 0, the threaded end of which is provided with a clamping-nut, D, having a handle, E, by which it may be operated.

5 The said pin is adapted to swing upon its pivots, by means of which it can be thrown into position between the lugs e, and the parts a b firmly and securely clamped to the spoke by the screw-nut D.

The letter F indicates a vertical shaft pro other end.

(No model.)

vided with a permanent crank, G, at one end, and screw-threaded, as shown at H, at the The said shaft is journaled in bearings I on the part a of the clamp, and between the two bearings, and fitted to the screw- 5 5 threaded portion of the shaft, is located a screw-nut, K, one edge of which abuts against the face 9 of the part a to prevent turning and cause the shaft to travel back or forth as the shaft is rotated.

The letter L indicates a lixed collar on the shaft F, and M a loosely-fitted forked or bifurcated dog mounted upon said shaft above the collar, the upper ends of which straddle the spoke and are adapted to set under the innor side of the folly.

The operation of my improved device is as follows: The clamp is opened on its hinge and placed upon-one of the spokes, when the parts are brought together and clamped by means of the pivoted pin and clamping-screw. The bifurcated parts of the dog are placed against the inner edge of the felly, and upon rotating the screw-shaft in the proper direction by means of the crank it will be elevated, the collar thereon elevating the bifurcated dog and lifting the felly away from the end of the spoke a sufficient distance to admit of the insertion of a split washer of leather orother similar material,by means of which thefelly maybe tight- 8o ened upon the wheel readily and conveniently.

It will be seen that as constructed the parts of the device are all permanently connected together and are not liable to be lost, and that the device is always in a condition ready for immediate use.

I am aware that clamps constructed in two parts and adapted to forcibly grasp and hold a spoke by means of securing bolts, nuts, and the like, have been employed heretofore in con- 0 nection with a stock and a threaded shaft, and having a dog for a similarpurpose; but in all such devices known to me the clamping-bolts were passed through holes made in flanges upon the spoke-clamp, and a wrench or other 5 separate tool was necessary for successfuloperation of the device.

In my device there is an entirety and no separate or disconnected pieces. It may be operated in the dark as well as in the light, as

there are no holes through which bolts must the hinged clamp A B I, the lever-nut D E, pass, and hence register therewith. screw-nut K, shaft F, having fixed crank G Iattach greatimportance to thehinged spokeand collar L, and the bifurcated loose dog M, 15 clamp A,in contradistinction to a clamp made all constructed, arranged, and combined to op- 5 1n sections and held by bolts and nuts, and erate as and for the purposes herein set forth.
