TOOL FOR REPAIRING AXLE-ARMS.

SPECIFICATION formingpart of Letters Patent No. 232,407, dated September 21, 1880. Application filed March 6, 1880. (No model.)

To all whom "it may concern Be it known that I, LEROY S. Lnwrs, of Rockville, in the county of Tolland and State of O0llll6OLl0llt-, have invented certain new and useful Improvements pertaining to a Tool for Repairing Axle-Arms, whereof the following is a specification, reference being had to the accompanying drawings, where- Figure 1 is a front view of the device. Fig. 2 is a side view of same. Fig. 3 is a frontview of the device when adjusted for cutting the thread. Fig. 4 is a view of a part of the lever and auxiliary arm in longitudinal section on the plane :20 at. Fig. 5 is a view of the threading-tool.

The hubs of vehiclewheels usually bear within them an axle-box, which at first, and when'theparts are new, has no longitudinal motion on the axle-arm; but after use, in consequence of the wear of the parts, this axlebox gets to have such longitudinal motion, which is an undesirable thing.

The device which I have invented is for the purpose of making such repairs of the axlearm that such longitudinal motion of the axlebox shall be prevented.

The letter a denotes an axlearm, bearing near its smaller end the shoulder 1), leading down to the threaded spindle c, which in use carries the nutd. Said axle-box is borne on said axlearm between the shoulder e and the nut 61.

I cure said trouble I have mentioned by cutting back the shoulder 12 and lengthening the thread 0 correspondingly.

The letter f denotesaleverbearing, as a fulcrum-orifice, the mortise g, the shape of which is in one particular peculiar and essential. The peculiarity is, that this mortise, on the side thereof opposite the lever, is V-shaped, to fit to axle-arms of different diameters.

The lever f bears an auxiliary arm, h, which bears a corresponding \l-shaped fulcrum-orifice, 43. These two fulcrum-orifices, in conjunction with the clamps hereinafter mentioned, hold the whole tool in proper position on an axle-arm to properly operate.

The letter j denotes a U-shaped clamp appurtenant to the lever f, the legs of which pass out through the end of the lever, and these bear the thumb-nuts k k, by the manipulation of which the clamp can be made to bear against the contained axle-arm, and thereby hold the axle-arm to place to be operated on. The springs ll under the thumbnuts allow the clamp to give with irregularities in the axle-arm. The auxiliary arm It bears, for a similar purpose, the U shaped clamp j" bearing similar thumb-nuts it It and similar springs.

The mode of using this tool to cut back the shoulder b is as follows: The cutting-tool m is laid into its socket a, and fastened to place by the'clamp-bar 0 and the set-screws o 0, the whole tool being meanwhile adjusted on the axle-arm. The nut d is then run upon the threaded spindle 0 till it bears against the side of the tool m. The lever fis then rotated on the axle-arm, the feed of the cutting-tool being given by rotating the nut d against it. The radial mortise p in the head of the lever f gives opportunity to inspect the depth of the out.

To cut the thread farther back on the spindle, the thread-cutting toolr is put in the place of tool m, its point coinciding with and entering the thread already cut. The nut cl is run up against the tool, the wrench s applied to the nut, and the pin 6 insertedin one of the holes a, to make the wrench and nut move synchronously with the lever. Then by rotating the lever f the tool will be caused to cut a thread on the spindle c, the proper feed being given thereto by the synchronous movement of the nut and the thread-cutting tool.

There is a series of the holes a in the side of the lever-head, so that the pin t may properly unite the wrench and the lever head however the nut may happen to stop when run up against the side of the thread-cutting tool, for, obviously, it will not answer to rotate the wrench independently of the lever after the thread-cutting tool has been entered into the thread already cut and the nut has been run up against the side of the thread-cutting tool.

The auxiliary arm It has two longitudinal mortises, w w, and the headed set-screws g 3 run through them into the lever f, whereby the auxiliary arm may be adjustably set upon the leverf.

I claim as my invention 1. In combination, the lever f, having the cruni-orifice g and series of holes 10; clamp j, V-shaped fulcrum-orifice g and the tool-socket rench 8, and an operating-tool, substantially n, the auxiliary arm h, having the V-shap'ed asjherein shown and described.
