SPECIFICATIONfoiming partof Let'lers Patent No. 317,694; dated May 12, 1885.

Application filed Maieh 26, 1884. (No model.)

To all whom it 17mg concern;

of Greensburg, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Devices ior Cutting and Screw-Threading Wagon-Axles; 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 which it pertains to make and use the same.

vices for cutting and screw-threading wagonaxles; and it consists in certain features of construction and in coi'nbination of parts here inafter described, and pointed. out in the claims. The boxing in the hub of a wagonwheel, when the parts are new, should fit snugly endwise between the back shoulder on the axle and the nut in front. As the parts ii I butt, respectively, against the outer and inner Be it known that 1, GUnnoiv H. \VILLIAMS,

ends of the feed-screw 0, so that the end ntion of the spindle and attached cutter-head is governed entirely by the said feed-screw. The inner end of the cutter-head is provided with a recess, into which the tools F, G, and H are successively inserted as required.

I I are yielding arms secured to the outside of the part A, and are provided at their other 60 ends with the clamping block or jaws J, that My invention relates to improvements in de i become worn, there is considerable eudplay between the axle and the said boxing in the hub of the wheel, that is ior various reasons The nut when screwed up butts against the outer shoulder of the axle. In 01 der to take up the lost motion, this shoulder is-cut farther back and the thread cut farther on the axle, and to make a finished job the end of the axle should be dressed off,

so as not to protrude through the nut. Eily improved apparatus furnishes a simple and eii'ective means of doing such work.

In the accompanying drawings, Figure 1 is a view in side elevation, and Fig. 2 alongitudinal section, ot'niy improved device. Figs. 3 and 5 are perspective views of the face of the respective milling burrs or tools. Fig. -iis an end view (,t'the tliread-cutling device.

A represents the body of the device. It is circular in cross-seciioinand the larger end is provided with a cylindrical bore, in which operates the revolving cutterhead B. The bore of the smaller end is threaded to engage the feedserew (1-, that is provided with the hand wheel a. This screw is provided with a central longitudinal here, through which passes the spindle D, that is secured at the inner end to the cutter-head B, so that the two parts will turn together in either direction. The

outer end of the spindle is provided with the crank E, secured by the setserew c. The hub of the crank and one end of the cutter-head are adapted to grasp the axle, and are open ated by the screw ii of the yoke L, by means of which the part A is held rigidly endwise on the axle. 6 The cutting-tools are each provided with a hole or groove, and the cutter-dread Bis provided with adowel-pin, or ecpiivaleutdevice, for entering said hole or groove on the respect ive cuttertools, by means of which the tool is caused to revolve with the head B. The tool I", which is first inserted, having a central bore, slips over the threaded part of the axle, and its face is provided with teeth that engage the shoulder on the axle. By means of the feed-screw U and the hand-wheel 0a pressure is brought to bear, forcing the tool against the said shoulder, and as the tool is rotated by means of the said crank, connecting-spindle, and cutter head, the shoulder is quickly So cutback the required distance. h ext, the tool F is removed and replaced by the tool G, that is simply a screw-threading die of the variety known as solid dies. These dies are made I right and left handed, and of proper size and lead of thread to fit the threads already on the ends of the axle. In operating these dies by the crank E, the handwheel c should be turned so as to follow up the die in its engagement with the thread oi. the axle until the die reaches 0 the new face of the shoulder. By this means a continuation of theformer thread is out still larther, so that the nutot' the axle may be .crewed up until it butts against the newlycut shoulder. Next, the tool Ii is placed in 5 position. This tool is a solid block with a slightly-concavel end provided with teeth, and is operated in a similar manner to the tool I by means of which the end of the axle is dressed oil, so as not-to protrude through the T00 axle-nut when the said nut is screwed home.

By means of the flexible arms I the machine,

z the inner end, and provided with suitable while held rigidly endwise, may move more or less laterally, so that the cuttingtools may adjust themselves to the axle.

The machine is simple, durable, and eft'ect- 5 ive, and weighs only a few pounds, so that it 5 may be easily handled and operated. When 1 one end of the axle is raised to remove the 1 wheel for oiling the bearing, if it is found that l body, ofiiexible arms secured to said body, there is end-play, after the wheel is removed Z blocks secured to the free ends of the arms, it requires but a few moments to dress the l and ayoke and set-screwforlocking the blocks axle in the manner described, so that the parts to the axle, substantially as set forth. will fit as well as when new. 4.
