MAURICE I. AKERS AND ARTHUR D. SEIIBER'I, 0F PENDLETON, OREGON.

CUTTING-TOOL;

United States, residing at Pendleton, in thecounty of Umatilla and State of Ore on, have invented certain new and useful mprovements in Cutting-Tools, of which the following is. a specification, reference being had to the accompanying drawings.

This invention relates to improved cutting tools, and an. object is to providev a device of this kind especially adapted for turning up worn bearings for crank shafts, such as used on automobiles, gas tractors, trucks and the like.

A. further object involves the provision of a tool whichis simple, efiicient and practical in construction, capable of being cheaply manufactured, and sold at a reasonable profit.

Another object involves the provision of a tool comprising a frame or body having means adjacent which the work is disposed, in combination with a slide mounted in guides of the frame or body, with means for adjusting the slide, whereby a cutting member may be adjusted toward and from the work, sothat the work can be out to any suitable size or diameter, and so that any suitable amount of material may. be moved from the crank shaft or other work operated upon.

While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptibleto changes, and the right to these changes is claimed, provided they are comprehended. within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be herein after set forth, shown in the drawings and claimed.

Application filed April 3, 1920. Serial No. 371,079.

for clamping the cutting tool proper in position, in full lines and part in dotted lines. Referring more especially to the drawlngs, 1 designates a frame or body member which may be any suitable shape and size, preferably elongated as shown, and may be made of any suitable material, preferably cast iron or steel, constructed in one piece as shown. This body has an upstanding portion 2 which is at right angles to the face 3 of the body. The body or frame is provided with an elongated slot 4, and guided in rabbets 5 of this slot is a slide block or cutting tool holder 5. Passing upwardly through the block 5 is a cap screw or bolt 6. This cap screw or bolt 6 passes through clamping plate 7 and is threaded into a tapped hole in the block. The forward upward portion of the slide block has an angle recess or rabbet 5 in which a suitable cutting tool or knife proper 8 is secured. A plate 9 is mounted upon the upper face of the slide block 5 and has one end overlying the cutting tool, in order to clamp the tool in the recess 5". The plate 9 has a downwardly extending lug 9 which fits into a cavity 9 in the upper part of the slide block, to assist in holding the plate 9 in position. The plate 9 is held in clamping relation to the slide block and the cutting tool proper 8 by means of a cap screw or plate 9 in position and agalnst the cutting tool proper. However, it is to be noted that this cap screw or bolt does not clamp against the clamping plate 7, as the tension and the position of the slide block is governed entirely by the cap screw 6.

The upstanding portion 2 of the body is provided with an angular recess or cavity comprising a pairof faces a, a. Thesefaces are formed on inclined planes extending at 45 angles from the upper face or plane 3 of the body. However, the faces a, a are constructed at right angles to each other, as shown. These faces may be tempered. or

the faces may be constructed by providing finger is held in position. Also rising upinsert plates of tempered steel, and connected to the upstanding portion 2 in any suitable manner not shown. The upper end of .the portion 2 is provided with an opening 13, rectangular in cross section for the reception of the shank 14 of the work holding finger 14. The work holding finger 14 extends at right angles to the finger 14 and depends in a direction toward the work to be disposed adjacent the right angle faces a, a, thereby cooperating with said faces, to assist in guiding the work during its rotation and at the time it is being turned up. The shank 14 of the work holding finger fits the opening 13 closely. The shank 14 of the work holding finger has a reduced extension 14", which is threaded, and is adapted to receive a threaded nut 15. This nut comprises a flange and a sleeve.

By means of this nut 15, the work holding wardly from the body or frame 1 is an upright standard 16, which is cast upon the body of frame 1 and is provided with a tapped opening 16 for the reception of a threaded screw 17, one end of which is swivelly connected to the slide block as at 17 in any suitable manner. A graduated sleeve 18 is suitably connected to the upright or standard 16, and is provided with graduations 18 This graduated sleeve 18 extends in a direction from the block 5, and

telescopically enters 'a sleeve 19 which is carried in any suitable'manner by the hand wheel 21 having a handle 22. This hand wheel 21 is suitably connected to the screw 17 preferably integrally therewith, though not necessarily, and it is obvious that by adjusting the screw in one direction or the other, the slide block may be moved toward and from the work to be turned up. The sleeve 19 on its marginal beveled edge is provided with a series of graduations 20, which, by the rotating of the hand lever 21 are adapted to cooperate with the graduations 18, for gaging the depth of the cutting tool proper 8. In other words, when rotating the hand wheel, the slide block canbe moved toward the work and the depth of the cutting tool proper 8 gaged according to the cooperation of the graduations 18 and 20 of the two telescoping sleeves '18 and 19.

In the operation of the device, the work holding finger 14 is first removed by removing the nut 15 and sliding the finger out of the opening 14 The body or frame may then be adjusted, and the work or crank '.-shaft to be turned up is then disposed in the.

cavity or recess of the upstanding part 2. The slide block is then adjusted or moved back so that the tool proper 8 can be placed in the recess5" and clamped. However, before adjusting the block toward the upstanding part 2, the work or crank shaft to be-turned up is first placed in the angular cavity of the upstanding part 2 and the work holding finger replaced and the nut 15 turned home. The work guiding finger 14 is positioned relatively close to the work or shaft to be turned up as indicated by the character I), after which the sliding block is adjusted toward the work so that the cutting tool proper may be in a position to act upon the work, its depth being governed by the adjustment of the hand wheel.

Should it be desired to use the tool in connection with a lathe, the elongated shank portion 23 of the body is rested or supported on the ways (not shown) of the lathe after which the lathe is operated slowly,

.the work to be turned up being rotated at the same time, in which case the cutting tool proper will act upon the work, and turn it up as may be desired.

From the foregoing it is to be noted that the present invention involves various advantages over the old method. For instance, the present device is simple in construction, and furthermore the tool may be applied in position with great ease. Furthermore, the cutting tool, mounted as it is, requires no vertical adjustments as it is always in correct position. iVhen the device is used in connection with a lathe it is in a position that insures the cuttings to fall away from the work and are not carried around asis apt to occur with other tools now in use which operate in reverse positions. Furthermore, the tool operates in a position leaving the work visible at all times, making it possible for the operator to watch the progress of the work, which is very important, and is one of the main features or advantages of the device. However, the tool may be operated by hand,

-for instance, by holding the work or crank shaft to be turned up in a vise, and applying the tool or device to the work in the manner above set forth, and after which the tool or device may be swung around the work by hand instead of the tool or device remaining stationary and the shaft or work to be turned up rotated as would be the case where the tool is operated in connection with a lathe.

The cap screw 10 operatively engaging the slot 4 constitutes additional means for guiding the slot block when adjusted.

The invention having been set forth, what is claimed as new and useful is 1. In a tool of the kind set forth, a body having an upstanding arm at one end provided with a work receiving cavity, working guiding means on said arm overlying the work, a cutting toolcarrying element operatively guided on the body and carrying a cutting tool to be positioned upon the work, means operatively mounted on the body and connected to the element for adjusting the same toward and from the work, means passing through the body and operatively means at one end, a slide element operatively guided upon-the body, a cutting tool carried by the body, means for adjusting the element toward and from the work, clamping means for the cutting tool proper, means passing through the element and operatively engaged with the clamping means for holding it clamped upon the cutting tool proper, said means passing through the element having means operatively passing through the body to assist in guiding the element when adjusted;
