The invention relates to a simple and portable device for cutting cable and structural shapes including rounds, squares, rectangles, Ts, channels, I-beams, H-beams, angles, bulb sections, reinforcing iron and other sections of similar nature, smoothly and with little effort on the part of an operator through the use of a movable cutter. preferably hydraulically actuated, passing through and guided in a space provided in a closely fitting and mating die.
One object of our invention is to provide acutter which is portable and easily and conveniently 'Another object of our invention is to provide interchangeable dies with the dies grooved to take the flange of angleirons, T's, channels, I-beams, Fl-beams and similar structural shaps.
Another object of our invention is to provide interchangeable punches and mating dies for punching holes in structural sheets or shapes.
Other valuable features will be apparent from the following detailed description and drawings which are intended as illustrative only and not as limiting the invention to the particular details wt forth.

According to the preferred embodiment of the invention the improved wire rope or other structural shape cutting device consists of a die mounted in a housing or support, preferably hinged to a base which base houses a. hydraulic or other jack so that by swinging the hinged support outwardly a wire rope or other structural shape may be inserted within the cutter after which the hinged support is swung back and secured in position. Below the die and attached to the hydraulicramof the jack is mounted the cutting blade which is adapted to pass through a space formed between two adjacent sides of the die, and thereby shear the wire rope or other structural shape. In the case of structural shapes such as angles, T's, channels, H-beams, li-beams and bulb sections, the blade first pierces the section and then continues to shear through the section.'
Referring to the drawings in detail it indicates a suitable base for the portable apparatus which base is preferably provided with a carrying handle it integral therewith. Mounted within the base is a suitable jacl: l2 preferably of the hydraulic type and is herein shown provided with a cylinder 88 Within which works a piston or plunger it. A fitting i5 is provided for supplying or removing pressure fluid. A suitable operating handle it and sockets fill and 3t may be provided in the cutter base til opposite the jack pump side to provide for the insertion of a rod ill for stabilizing the apparatus during the cutting operation. The
Jack may be oiany suitable construction and while the hydraulic'jacl: is preferred pneumatic or other fluid operation maybe employed within the scope of the invention.
According to the preferred embodiment of the invention a cutter member A is carried by the piston is or other movable portion of the lack. Various cutter shapes are shown in Figures 5 to 13 and it will be understood that these are illustrative only, and that others may be employed for cutting difierent shapes. Figs. 5 and 6 show an inverted V-shaped cutter with the center of the v on the center line of the cutter. Fig. 7 shows an inverted V-shaped cutter with the centerdine of the v ofiset with respect to the center line oi the cutter. In Figs. 8 and 9 a cutter and die for shearing structural shapes are illustrated. In Fig. 10 a cable cutter is illustrated, this being the form shown in -'connection with the complete 'apparatus in Figs. 1, 2 and 4. In Figs. 12 and 13 punch and die members for use with the apps. ratus are disclosed.
In each case the cutter member or blade slidably fits in a groove or recess formed between the two sides of a die member B. As shown in Fig. 4,
the die member is provided with two lips 32 and 33 between which there is provided a recess 'or space 34 within which the cutter blade accurately fits so that there is a telescoping operation when .the blade is moved upwardly. While the cutter blade is preferably the movable member a reversal of parts is contemplated and it is within the scopeof the invention in its broadest aspects that the cutter should be stationary and the die movable.
As shown in Fig. 4 the cutter blade A is tightly fitted in a slot l8 in-the piston II and secured in place by means of a pin i9,
' member, a hydraulic jack The .die B is similarly, secured within a. support or housing which is fixed with reference to the base when the cutter is in operation but is adapted to be swung outwardly to permit the work to be applied. .One or more pins 21 may be employed forsecuring the die in place. Above the die a suitable opening 22 may be provided for the discharge of punchings.
As shown in Fig. 1 the die support 20 is provided with an arm 23 hingedly secured to the base at 24. This permits the arm to be swung outwardly for applying the work and swung back when the work is in place. A suitable-holding arm 25 is hingedly mounted at 26 and is adapted to be se-- cured to the support 20 by means of a pin 21 or other suitable fastening means.
To operate, the hinged cover or support 20 is swung outwardly and the wire cable or bar is laid on the edge of the cutter blade A. The hinged support or cover is then swung back into position and through the operation of the hydraulic'jack and piston ll the cutter blade A is a forced upwardly through the material to be cut, finally being completely forced into the die.
Before cutting cable it is preferable to, seize .the rope on each side of the point to be cut so as to prevent spreading of the strands and to insure a square cut.
With cable cutters requiring the use of heavy blows of a hammer to drive the cutter through the cable, there is also a tendency for the cable to jump on the rebound from the hammer blow and before the cutter is struck again the point of first penetration must be aligned to the cutter. This procedure is repeated until the cutter is. driven deep enough into the cable to stick. Obviously, this disadvantage is avoided according to the present arrangement. Also incable cutters requiring the use of heavy blows from a hammer to drive the cutter through the cable, the cutter must rest on a solid foundation or the resiliency of the foundation will absorb practically all'the I force from the hammer.
According to the present design any ordinary flooring is satisfactory or the cable cutter may be applied to a cable in mid-air and work as well.
It is also within the scope of the invention, in'
its broadest aspects, to make the base and reinforced die housing a single one-piece unit open I at both ends and one side so that the cable or other structural shapes may be readily inserted for cutting at any point of their length.
, Other modifications and variations will be apparent within the scope of the appended claims. It will be understood that one of the important features of the invention is the interchangeability of the various die and cutter members, each of which is rigidly held in a suitable groove inits supporting member. and one or more pins.
