TRAVIS T. THOMPSON, OF BOGATA, TEXAS.

VEHICLE-SPINDLE Specification of Letters Patent.

Patented July 28, 1908.

Application filed September 17, 1907. Serial No. 393,262.

To all whom it may concern:

Be it known that I, TRAVIS T. THOMPSON, a citizen of the United States, residing at Bogata, in the county of Red River and State of Texas, have invented certain new and useful Improvements in Vehicle-Spin dles, of which the following is a specification.

My invention relates to that class of buggy, carriage and wagon axles, or axles of other light vehicles, in which the spindle of the axle is provided with an adjustable and removable sleeve. This sleeve may be turned on the spindle from time to time, presenting new, unworn surfaces until worn out, and then it may be entirely removed and a new one substitutedin its place. Thus it will never be necessary, on account of the wear of the sleeve or spindle, to remove the axle, and thus great time, labor and expense are saved.

In the accompanying drawings, Figure 1, is an elevation of my invention. Fig. 2, is a longitudinal view of my invention, the spindle being in elevation, the sleeve and nut in section.

In describing my invention I read the drawings from left to right.

My invention is described as follows In the accompanying drawings the numeral 1, represents the axle; 2, the large shoulder; 3 the small shoulder and 4, the spindle. This invention is applied toboth ends of the axle. Each end of the axle for some little distance, is provided with a thread 5, and the large part 3 of the spindle is provided with a thread 6, and the small part 4, of the spindle is also provided with a thread 7. These threads all correspond with each other in thickness, depth and pitch, and are right and left.

A sleeve 8, whose inner surface "exactly corresponds with the outer surface of the axle and spindle just described, and whose inner surface is provided with threads which exactly correspond in thickness, depth and pitch with the threads on the axle and spindle just described, is secured on said spindle.

The large part 3 of the spindle and the enlarged part 6 of the sleeve, are for the purpose of strengthening the spindle at the point where it is likely to be worn most, and broken.

Screwing on the threaded end of the spin dle is a safety nut 9, having an inwardly projecting rim 10. The purpose of this rim 10, is to form a smooth surface to fit against the outer end of the hub, and at the same time leave an oil well 11.

The rear and flange part of the hub runs backwardly and fits over the integral elevation 12, of the sleeve, which elevation 12, is provided with an annular oil well 13. Said sleeve is also provided in its'large and small parts with oil wells 14 and 15, respectively. There may be more of these oil wells if desired. The rear part 16, of the sleeve is square or octagonal, preferably octagonal, so that the sleeve can be screwed on and off from the axle and spindle.

Screwing into perforation 16 in the rear 73 part of the sleeve and into recesses 17 in the threaded part of the axle is a set screw 17, countersunk when screwed home. There may be several of these recesses 17 around the threaded part of said axle. When the 75 sleeve becomes worn, on its under side, I loosen the set screw 17, and turn the worn part to one side, and then turn the set screw into another recess to hold .the sleeve in place, and when worn again I repeat the same operation until all the annular surface of the sleeve has thus been gone over, and when worn out I remove and replace it by a new one.

Having described my invention, what I 8 claim as new and desire to secure by Letters Patent, is r 1. The combination of a vehicle axle, terminating at each end in a spindle, each end of said axle provided with a thread 5, and each threaded portion with recesses 17 the spindle parts having large parts 3 each provided with a thread 6, and a small part 1, provided with a thread 7, all of said threads having the same pitch and being the same size, and sleeves 8, their inner surfaces corresponding to the outer surface of said axle and of said spindle, and having threads corresponding to said threads 5, 6 and 7, the spindle part of said sleeves corres onding in shape to the spindles of said ax e; integral enlargements 12, extending from the inner end of said sleeves, each enlargement provided with an annular oil well; integral extensions extending from the rear part of said enlargements, and fitting over the threaded part of said axle, said extensions each provided with a screw-hole 16 substantially as shown and described and for the purposes set forth.

2. The combination of a vehicle axle, ter- 119 minating at each end in a spindle, each end of said axle {provided with a thread 5, and

each threaded portion with recesses 17 the spindle parts having large parts 3 each provided with a thread 6, and a small part 4, provided with a thread 7, all of said threads aving the same pitch and being of the same size; sleeves 8, their inner surfaces corresponding to the outer surface of said axle and of said spindle, and having threads corre sponding to said threads 5, 6 and 7, the spindle part of said sleeves corres onding in shape to' the spindles of said ax e integral enlargements 12, extending from the inner end of said sleeves, each enlargement provided with an annular oil well; integral extensions, extending from the rear part of said enlargements and fitting over the threaded part of said axle, said extensions each probetween the inner faces of said rims anc the outer faces of said sleeves, substantially as shown and described and for the purposes set forth.

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

TRAVIS T. THOMPSON.
