EMANUEL FOERSTER, OF NEW YORK, N. Y.
PIPE-CUTTER.
SPECIFICATION forming part of Letters Patent No. 402,730, dated May 7, 1889.
Application filed June A2, 1888. Serial No. 275,885. (No model.)
To @ZZ whom it may concern.-
Be it known that I, EMANUEL FoEEsrEE, a resident of the city, county, and State of New York, have invented an Improved Pipe or Bar Cutter, of which the following is a speciiica tion.
The object of my invention is to produce a device that will cut a pipe or bar of varying dimensions, which shall be simple in construction, easily operated, and effective in use.
The invention consists in the details of improvement an d the combinations of parts that will be more fully hereinafter set forth.
Reference is to be had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation, partly broken, of my improved cutting device. Fig. 2 is a side elevation at right angles to Fig. l. Fig. 8 is a horizontal cross-section on the line c c, Fig. l. Fig. 4. is an enlarged detail sectional view of a portion of the cutter-feeding device shown in Fig. 1. Fig. 5 is a horizontal crosssection on the line Za Zr., Fig. l.
In the accompanying drawings, the letter A represents the head of my improved cutting device, which at its upper part is recessed to fit against a tube or pipe.
B is a jaw that passes at one part over the top of the head Af The shank ct of said jaw B passes downward through an opening, b, at one side of the head A. The lower part of the shank a is screw-threaded and receives a nut, CZ, that is adapted to press against the head A to hold the jaw B upon a tube or pipe, D, as shown in Fig. l.
E is the cutter, which consists of a blade having its end adapted to contact and cut a pipe or bar. This cutter or blade E is carried by a sliding block, F, that is guided in suitable grooves or otherwise on the head A. My preferred mode of securing the cutter or blade E to the sliding block F is to place the cutter in a recess, e, in the sliding block F, and to place on the block F and over said cutter E a plate, f, that bears upon said cutter and holds it in said recess. (See Fig. 3.) This plate I secure to the block F by means of screws g. By this construction the cutter E may be readily adjusted lengthwise on said block F, and be securely held thereon; but
said cutter or blade E may be otherwise held to the sliding head F.
In order that the cutter E will not be fed too rapidly into the pipe byturning the feeding-screw, I construct my feeding device for said cutter as follows:
To the head A, below the sliding block F, is secured a tube, G, that is provided with internal threads, h.
H is a tube that is adapted to pass within the tube G, and it is provided with external threads, 2'., that mesh with the threads h in the tube G. The tube H carries a cross-piece or handle, j, at its outer end. The tubes G H constitute the handle proper, or means for turning the device' for cutting a tube or bar. The tube H has internal threads, Z, that are adapted to receive a screw-rod, I, that is secured at one end to the sliding head F. Vhen the tube H is turned, say, to the right, it will advance within the tube G, its internal threads, Z, advancing on the threads of the rod I to prevent the tube H pushing the head F too fast. I prefer that the external threads, o', on the tube H should be less to the inch than the internal threads, Z. A good proportion I find to be as follows: The external threads, z', ten to the inch, and the internal threads, Z, and the threads on the rod I to be twelve to the inch. By this means as the tube H is turned to advance within the tube G it will move up ten threads to the inch, and by only acting on ten threads out of the twelve on the rod I will move said rod, and thereby the head F, up the distance of two threads on the rod I, which would be two-twelfths or one-sixth of an inch. Vith this construction the tube H may be given a whole turn by the operator without fear of pressing the cutter E too deeply into the pipe to be cut; but the relation of the threads e' Z to veach other may be varied to suit the desired distance that the cutter shall move at each turn of the handle or tube H. I-Ieretofore where the cutter was moved up the same distance that the handle moved in, the operator had to be careful to give said handle but a very slight turn, otherwise the cutter would be jammed against the pipe and the cutting operation would `be prevented or the cutter injured. By my improved feeding arrangement the operator IOO need not have fear of turning the tube H at a single turn so much as to injure the cutter. With this construction of cutter a rod or pipe of greater thickness can be eut than has heretofore been permissible with a rotary cutter. As the cutter or blade E may be moved farther out from its carrying-head F when desired, the thickness of pipe to be out is limited only by the length of the cutter E.
Having now described my invention, What I claim is In a pipe-cutter, a Cutting-tool combined with the screw-rod I, connected therewith, in-
ternally and externally threaded tube H on said rod I and engaging with the thread 15 thereof, and internally threaded tube Gr around the tube H, the threads on the tubes G and H engaging, whereby the rod I will be moved but a slight degree with relation to the movement of the tube H, substantially as dezo scribed.
