' MACHINE FOR RECUTTING AXLE-SHOULDERS.

SPECIFICATION forming part of Letters Patent No. 547,025, dated October 1, 1895.

Application filed December 29,1894- Serial No, 533,273 (No model.)

To aZZ whom it may concern:

Be it known that I, SOLOMON D. NORTH, a citizen of the United States, residing at Plainville, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Machines for Recutting Shoulders Upon the Ends of Axle-Arms, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure 1 is an exterior view of the entire tool. Fig. 2 is a view of the same in central longitudinal section on the plane denotedby the broken line m at.

The primary object served by this tool is the recutting of the shoulders at the outer extremity of the axle-arms of vehicles, for the purpose of permitting the nut which is commonly borne upon such extremity to be turned up a little farther than was originally intended, so as to compensate for endwise Wear of the axle-box and cooperating parts. The tool can also be used for other purposes than that above indicated.

In the accompanying drawings, the letter a denotes an axle-arm to which the tool is attached.

b denotes a sleeve loosely inclosin g the axlearm.

0 denotes a key, of which there are three or more, each lying in a longitudinal slot made for that purpose in the sleeve 1), and they are used for centering the sleeve 1) in place upon the axle-arm and there holding it after it is so centered. These keys are simultaneously and synchronously moved radially toward a common center by means of the compressorring d, which is interiorly screw-threaded and has that thread co-operating with a corresponding thread upon the collar 6.

The letter f denotes socket-holes, more or less in number, sunk in the compressor-ring for the end of a small wrench-bar, whereby the compressor-ring may be rotated.

The tool, as a whole, is centered and fastened and placed upon an axle-arm by means of the devices and parts so far described. The forward portion of the sleeve 19 carries a screwthread I), co-operating with a corresponding screw-thread upon the interior of the feedsleeve g, and it is by the rotation of this feedsleeve 9 upon the axle-arm-inclosing sleeve 1) that the cuttin -tool, soon to be described, is fed back and forth. The feed-sleeve is rotated by any suitable meansfor instance, feed-wheel g.

On the feed-sleeve is hung the rotary toolcarrier h, through the medium of a flange g on the feed-sleeve and corresponding inclosing parts, which are constituents of the toolcarrier. The tool-carrier has a socket (or it may have more than one) h, carrying a cutting-tool i. The letter 10 denotes a wrenchsocket on the tool-carrier for the insertion of a wrench-bar to rotate the tool-carrier, and with it the cutting-tool, and do the cutting for reshouldering axles.

I claim as my improvement In combination, sleeve 19 carrying screwthread 19, keys 0, compressor-ring d, interiorly threaded feed sleeve g carrying flange 9 toolcarrier h rotarily hung on flange 9 tool-socket h, and tool 2', all substantially as described. and for the purposes set forth.

SOLOMON D. NORTH.
