WILLIAM G. WILSON, OF BAYONNE, NEl/V JERSEY.

PIPE CUTTER AND VISE.

SPECIFICATION forming part of Letters Patent No. 731,257, dated June 16, 1903.

Application filed November 1, 1902. Serial No. 129,784. (No model.)

To (Z5 whom, it may concern:

Be it known that I, WILLIAM G. ILSON, of

Bayonne, in the county of Hudson and State' of New Jersey, have invented a new and useful Pipe Cutter andVise,not heretofore known or used, of which the following is a full and clear description, reference being had to the accompanying drawings.

' and purposes will be more fully described hereinafter.

The object of my invention is to provide a hand-power machine by means of which pipe of diiferen't sizes may be firmly held and readily cut into different lengths. It is particularly adapted for use in cutting cast-iron pipe.

In the drawings, Figure l is a front view with pipe gripped. Fig. 2 is a rear view. Fig. 3 is a vertical mid-section in axis of gripped pipe. Fig. 4 is a sectional View substantially on the line 00 in Fig. 3. Fig. 5 is a detached View showing one manner of adjusting the support H on the base.

Referring to the drawings, A is a base-plate,

adapted to be secured to a table or other support by bolts 1) b.

B is a frame secured on the base A, between the two uprights of which slides the upper jaw C of a vise. At the bottom of the frame and resting on the base-plate is the lower jaw D of the vise. The upper jaw O is secured to the lower end of screw-bar F, which is threaded and travels in the frame B when turned by the sliding bar G, similar to the usual construction and operation of a press or vise. On the base-plate A at the end opposite the lower jaw D is a rest 'H, which is of the same height as the jaw D. The upper jaw O is provided with a grip c, which does not come directly over the lower jaw I), but is ofifset, so as to come between that and the support 11, in order that when a pipe is gripped between the two jaws it will be held at three points along its length.

On each of the two uprights of the frame B, I form face-plates I I, adapted to receive wings KK, which ,form a part of the cutting- I with them is a circular trackway or ring-like bearing M, adapted to receive a cutting-tool carrier N. The carrier N is heldin place in the circular trackway by the plate 0, which is secured to the rim of the bearing M by screwsf.

P is a cutting-tool socketed in a tool-holder R and held in position therein bya set-screw g. The cutting-tool holder R slides in ways provided in the toolcarrier and is adapted to be adjusted to and fro by a threaded rod S, turned by a handle T.

V indicates a piece of pipe in position to be out.

It will be seen that the pipe V rests at one point on the lower jaw of the vise and .at another point on the support H. These two points on which the pipe rests should be adjusted so that the pipe will be level and true and having its horizontal axis at right angles with the line on which the cutterP will travel when operated by the handle T and rod S.

The support H is located on the base-plate and may, be at any desired distance from the lower jaw D. If desired, it can be provided with means for adjustment to and from D, so that the distance will be varied to suit the length of the piece of pipe being out. In Fig. 5 one mode of such adjustment is shown. A slots is made in the base-plate, and the support H is provided on its under side with a corresponding formation which is passed through said slot and made to slide therein, a setscrew tbeing passed through the support H to steady it in position.

In one of the wings K are a series of holes h, through which a pin 71') when passed will enter a hole 71; in the face-plate I at points where the two holes are even. The holes 72. are arranged at points which will set the out ter for cutting pipes of different sizes when the pin is passed through them and into the hole 70. The tool-carrier N rides free in the strengthen this part of the cutting device, the

tool-carrier is braced by an excess of metal or flange W on each side of the tool-holder and also has a flange '1) at the rear to stiffen the parts.

The drawings, Fig. 3, show the preferred arrangement of the tool-holder with respect to the plane of the carrying-rest. To provide convenient access to the cutting-tool, the holder is set out of said plane.

I do not wish to limit myself to the exact construction or form of the different parts of my cutter, as these may be varied and the effectiveness of the device still retained.

The use of the pin k is to conveniently hold the circular track of the cutter in position at points proper for different-sized pipe until the thumb-screws L are turned to hold it there during the operation of cutting. The

essential feature of the device is the adj ustment of the cutter so that it will cut difierent sizes of pipe with a cutter which moves concentrically about the axis of the pipe whatever its diameter may be.

What I claim as my invention, and desire to secure by Letters Patent, is

' 1. A pipe-cutter having a tool-carrier traveling in a circular trackway, and a stationary holder to grip the pipe to be cut with means for adjusting the tool-carrier and trackway with respect to the holder so that the carrier will be concentric with different-sized pipes in the holder, substantially as shown and described.

-2. In a pipe-cutting device of the construction shown a jaw D and rest Hto engage the pipe at one side and a jaw O to engage the pipe at the opposite side, and means for adjusting the rest H to and from the jaw D substantially as set forth.

3. In a pipe-cutting device such as shown the tool-carrier N riding in a circular trackway M provided with wings K, K, and means for securing 'the same to the pipe-holder substantially as shown and described.

4. In a pipe-cutter of the character shown the tool-carrier N riding in a circular trackway 'M, said trackway being provided with means for securing it to the frame B and adjusting its position thereon substantially as shown and described.
