FRANK RICHARD, OF SUNFIELD, MICHIGAN;

AXLETREE REPAIR IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 705,868, dated 'July 29, 1902.

Application filed April 18.1902. $erial No. 103,638. (NomodeL) To. aZZ whont it nuty conccrn;

Be it known that I, FRANK R cHAnD,-a citizen of the United States, residing at Sunfield, in the county of Eaton and Stateof Michigan, have invented certain new'and-useful Im provements in Axletree Repair Implements, of which the following is a specification.

My invention relates to improvements in appliances for recnttingand repairing the ends of buggy-axletrees; and its objects are, first, to provide an implement wit-hiwhich the thread and shoulder on the end of an axletree may be repaired without the necessity of removing the axletree from the buggy, and, second, to provide a means whereby the position of the cutters in the implement may be adjusted to insure the repair of the ends of the axletrees without, changing the length of the screw-bearing for the nut that holds the buggy-wheel to place on the axletree. I attain these objects by themechanism illustrated in the accompanying drawings, in

which.

Figure 1 is an elevation of myappliance applied to the end of an axletree with one arm of the frame cut away to show the relative position of the adjusting-clamps and of the cutting-tools. Fig. 2 is a right-hand end view, and Fig. 3 is a left-hand end view, of the frame. Fig. 4 is an elevation of the frame with one form of my tool-adjusting attachment in place, and Fig. 5 is a plan of the ad.- justing device.

Similar letters refer to similar parts throughout the several views.

The frame of my implement consistsof an annular base or snpport A, arranged to pass freely over the axletree and having armsB projecting back and turned'in-to-uniteand form a cross at c. The inner diameter of the annular supportA and the distancebetween the arms corresponding therewith .is sufficient to admit of placing the clamps F, having the curved ends f,within them and around the axletree G and leave sufficient spaceto allow of considerable variation of adj ustment. These clamps are designed to be adjusted by the thumb-screws D and are designed, first, to perfectly cent-er the frame around the axletree; second,to hold the frame in perfect. alinement with the aXletree, for which purpose I prefer that one end of the clamps bear upon the screw-threads g at the end of the axletree, as they are sure to be perfectly centered, while the balance of the bearing-surface of the axletree may have becomeworn sufficiently to throw the cutters considerably out of center at some points, and,third, by setting the jam-nut 01 up solidly the end of the clamp may be made to assist greatly in holding the end of the cutter E from trembling .when cutting from the end of the axletree. The endsfof the clamps F are made concave to partly encircle the ends of the axletrees, and the cutter E should pass through the body of the clamp or rest against the side of it, as indicated in Fig. 1, and the adjusting screw D should pass through the clamp near the cutter, so that it would tend to hold it from sidewise motion, so that with the adj usting-screw properly adjusted and the jam-nut solidly screwed to place the strength of the screw, together with the bearing of the end of the clamp upon the surface of the end of the axletree, will almost Wholly avert the danger of the cutter-trembling when in use turning or cutting oi the end of the axletree.

E is a cutter for cutting 0d the end of the threaded portion g of the axletree to correspond with the amount cut from the shoulder g and thus keep the threaded portion the same length at all times. i

6 represents a rib or support in the arm B, so located that theback of the cutter IE will be supported, thereby to support the cutter against the danger of trembling when cutting from the end of the axletree, as hereinbefore described. v

The arm H is securely attached to the axletree by means of the bolt h or other suitable device, after which the frame A B is adjusted, as hereinbefore described, and the yoke I is placed in position, the ends passing throughapertures in the ends of the arms H,a properlyto assist to hold the frame in proper alinement,

and,second,to feed the frame along as thecutters do their work. The latter is attained by the proper manipulation of the nuts 2', as may be readily understood by referring to Fig. 1. When the frame and yoke have been properly prepared bearingbeing passed over the jour- ICO face of the arm.

adjusted upon the axletree, the crank J is secured to the end of the journal 0, and the entire frame and its several parts are made to revolve around the axletree, when the knives are brought into action by properly adjusting the yoke through the medium of the nuts t', as heretofore stated.

As the screw g is not of uniform length upon all axletrees, I find it desirable to provide for adjusting one of the cutters, and have chosen the cutter E for the reason that to adjust the cutter E would be likely to remove it from its support 6 and endanger its trembling, and thereby doing its work in an-indifferent manner, and, further, there is not sulficient space both sides of this cutter to successfully secure it if made adjustable. In Fig. 4 I have shown the cutter E supported in a detached capB,havinganapertnrefor the cuttertopass through. This cap is so arranged that when securely bolted to the arm 13 by the bolts 1) b the cutter will be firmly held against the sur- The-cap is preferably provided with a rib at each edge, as at d d, that are so adjusted that they will closely embrace the opposite edges of the arm and hold the cutter as firmly edgewise against the pressure upon the end of the axletree as though it were held'in a closely-fitting mortise through the arm, as indicated in Fig. 1. This cap is provided with slotted apertures 79' for the reception of the bolts 19, so that it may be moved longitudinally to meet the necessary adjustment for the screw, as stated. I do not desire to restrict myself to this particualr means of supporting the adjustable cutter, but simply show it as one (a very convenient and perhaps the most available and most effective) means among several that will be readily constructed by mechanics versed in the art to which it belongs. One reason why this appliance is perhaps better than other forms is that it insures a much longer bearing-surface for the cutter and to that extent 'averts the danger of the cutter trembling when in use, as an adjustable cutter cannot well pass through the clamp F, as hereinbefore suggested in connection with a fixed cutter, and will need the additional support to lessen the danger of trembling.

The demand for an implement of this kind and allow the wheel to move endwise and cause a rattling or pounding of the parts, to obviate which it is necessary to either, first, place a washer upon the axletree, or, second, to place new skeins in the hub of the wheel, either of which is objectionable, or to shorten the bearing portion of the axletree, which would be expensive if necessary to remove the axletree from the buggy and do the work upon a lathe, while with this implement the work may be done very inexpensively and without the necessity of even removing the axletree from the buggy.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an implement for repairing axletrees, an arm adapted to be secured to the axletree, a yoke connected with said arm and projecting back beyond the end of the axletree, a frame within said yoke and having a central bearing through the body of said yoke, adjustable clamps within said frame and arranged to center said frame with the axletree, adjusting-screws passing through the frame and said clamps, cutting-tools supported in said frame and having intermediate supports between the frame and the axletree, substantially as and for the purpose set forth.

2. In an implement for repairing axletrees, an adjusting-yoke adapted to be secured to the axletree, and having a central bearing, a frame having a central bearing engaging the central bearing of the. yoke, said frame extending over the .axletree longitudinally, clamps within said frame, adjusting-screws actuating said clamps, a stationary cutter, an adjustable cutter, and a detachable and longitudinally-adjustable cap having an aperture for the cutter, and supporting-ribs, substantially as and for the purpose set forth.
