CUTTER FOR CAST-METAL PIFES.
SPECIFICATION forming part of Letters Patent No. 779,305, dated January 3, 1905.
Application flied March 3, 1904. Serial No. 196,373.
[0 cir/ZZ whom, it T12/Cty concern,.-
Be it known thatl, JosErH F. OLIVER, a citizen of the United States, residing in New York, borough of Manhattan, and State of New York, have invented certain new and useful Improvements in Cutters for Cast- Metal Pipes, of which the following is a specification.
This invention relates to an improved cutter for cast-metal pipes, by which the cutting operation is performed in a very satisfactory manner, cutting an even straight edge on the pipe without producing burs at. the inner or outer circumference of the cut edge and by which the cutting of any size of pipe can be.
accomplished in a quicker and a more eflicient manner than has been possible heretofore.
The invention also aims to provide a pipecutter which by virtue of the compact arrangement of its parts occupies little space and can be conveniently handled; and with these and other objects in view the invention consists in the pipe-cutter embodying the novel features and combinations of parts to be hereinafter described and claimed.
In the accompanying drawings, Figure l represents a front elevation of my improved tool for cutting cast-metal pipes. Fig. 2 is an end elevation of the same. Fig. 3 is a rear elevation of the improved tool; and Fig. 4f is a vertical transverse section on linel 4L, Fig. 3.
Similar letters of referenceindicate corresponding parts.
Referring to the drawings, A denotes the main frame of the improved pipe-cutting tool, said frame being formed in the shape of a fiat ring and divided into two sections a a', which are interconnected by means of bolts c c. passing through abutting lugs at the end of the sections, as shown. By unscrewing the nuts CZ d of the bolts c c' the sections c a of the main frame A can be separated so as to permit the application of the same to the pipe P in whatever position the said pipe may be located. After the frame A is placed around the pipe the fastening screw-bolts c c' are applied again to theiianged ends or lugs b b' of the main frame A. The main frame A is provided with a circumferential groove e, which forms a guideway for a movable ringshaped frame B, provided at its inner circumference with a tongue or runner f, fitting into the groove e of the main frame A, as shown in Fig. 4. The ring-shaped frame Bserves for supporting at one side of the tool the adjustable cutters C, and at the other side of the tool the main frame is provided with adjustable V-shaped grip-jaws g, the faces of which are made of steps L, arranged in V shape, so as to bind at diametrically opposite sides on the pipe. rPhe shanks j of the cutters C are guided in ways K of the ring-shaped frame B and adjusted by threaded stocks Z, which are guided in interiorly-threaded bosses m at the ends of the ways, as shown clearly in Fig. the outer ends of the threaded stocks Z being provided with handles for operating the cutting-tool by both hands.
The cutters C are inwardly adjusted from time to time as the cutting of the pipe is proceeding, so as to gradually increase the depth of the groove in the pipe until the cutting of same is complete. The jaws g g are swiveled to the ends of threaded shanks u n, which are guided in interiorly-threaded sockets@ o, cast on segmental iianges p p, arranged on the main frame A and extending outwardly at right angles to the plane thereof, so that the jaws g g remain in position on the pipe while the cutters O are moved with the ringshaped supporting-frame B around the same.
The cutting-tool can be turned either in continuous motion in one and the same direction around the pipe to be cut or in a forward-andbackward reciprocating motion, provided that the cutting-points are each so reciprocated around one-half the circumference of the pipe, one orv the other of these operations being necessary to effect a proper cutting of the pipe with my improved cutter. When the operation is completed, the cutters have effected an even and smooth cutting of the pipe without leaving any burs or rough projections at either the inner or outer edge of the cut portion of the pipe.
My improved tool forms a very effective device for cutting of cast-metal pipes in a comparatively short time, especially when the pipe is held in stationary position in a vise or similar grip, so that the tool can be applied in such a manner as to he turned continuously around or oscillated to and fro on the pipe.
The disposition oi the gripjaws andl cutters at opposite faces of the fiat ring-shaped inain Jframe is particularly advantageous,as the component parts of the device are thus disposed in approximately the same plane and the ease of handling the cutter is thereby greatly increased. Owing to the fact that the main frame is made in the shape of a ring or washer, the device occupies less space than those at present in use7 in which a comparatively long and cumbersome sleeve is employed.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A pipe-cutter 'comprising a ring-shaped main frame made in two separable sections and provided with a peripheral groove, iianges cast integrally with said main frame and pro- .jectingoutwardly from one face thereof, sockets cast on said flanges, grip-jaws adjustable in said sockets, a ring-shaped cutter-frame rotatable about said mainframe and provided on its inner surface with a tongue engaging said peripheral groove, said cutter-frame being made in separable sections similar to those of said main frame, guideways on the face of said cutter-frame at the side opposite said grip-jaws, and cutters adjustably movable in said guideways.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
JOSEPH F. OLIVER.
