BX ARMOBED CABLE CUTTER Harry L. Ailstock, Covington, Va.

Application July 3, 1941, Serial No. 401,035

1 Claim.

This invention relates to new and useful improvements in means for cutting BX armored cables in a quick and convenient manner.

The principal object of the present invention is to provide a cutter which can be held in the hand and brought to the work instead of requiring that the work be brought to the cutter and in any way clamped or held outside of the provision of the cutter structure.

Another important object of the inventionis to provide a tool for cutting BX armored cables at angles or on a square as the occasion demands.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the tool.

Figure 2 is a top plan view.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Figure 4 is a fragmentary end elevational view showing one of the depth gauge members in a position permitting the saw to cut entirely through the cable.

Figure 5 is a sectional view taken substantially on the line 5-5 of Figure 1.

Figure 6 is a sectional view taken substantially on the line 6-6 of Figure 4.

Figure 7 is a section on the line 1-1 of Figure 1.

Figure 8 is a fragmentary plan view of a piece of BX armored cable showing the same after a out has been made on an angle by the present cutter.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents a handle having a longitudinally extending bore 6 therethrough, in the lower end of which operates a plunger 1, the plunger having a threaded bore 8 for receiving the lower threaded end of an elongated rod 9 which has a laterally disposed detent hook In at its upper end and above the handle 5; The lower end of the plunger 1 has a kerf I therein so that a screw driver or the like can be used to unscrew the plunger 1 from the rod 9.

A plate |2 has a depending threaded boss I3 to which the upper portion of the handle 5 attaches and through the boss and the immediate portion of the plate |2 a bore is formed for slida-bly receiving the rod 9. Interposed between the plunger 1 and the boss l3 and located within the bore 6 is a compression spring l4, serving to hold the plunger 1 extended and the hook l urged downwardly into either an opening l or an it positionto keep a saw blade 28 stretched between the plate l2 has the threaded opening therein for receiving a threaded stud rising from the boss l3. The hook l0 and its shank are rotatable so as to change the hook engagement from one opening IE to the other opening IE or vice versa, depending upon whether a square cut across a BX armored cable I8 is desired or an angular cut.

Rising from the plate |2 are posts l9, l9 each of which is bifurcated at its upper portion to define a slot 2|! in which operates the back bar 2| of a saw structure generally referred to by numeral 22. An oblique handle 23 is provided at one end of this bar 2| while the other end is curved downwardly as at 24. A leg 25 is attachable to the handle end portion of the bar 2| by a bolt 26 and nut thereon. This portion of the leg 25 is reduced to accommodate the bar 2 I, the leg being provided with a block portion 21 overhanging the bar 2| and a set screw 28 is disposed through this block 21 to bite against the bar 2|, thus definitely holding the leg 25 in a swung the pins 30 and 3|, located on the leg 25 and downwardly curved portions 24 of the bar 2|.

Members 32 extend laterally from the post l9 and onthese depth cutting gauge members 33 are freely swingable and are held against the corresponding post by compression springs 34 on the members 32. Studs 35 project laterally from. the post l9 and the gauge members 33 are formed with small depressions for receiving the studs 35 to the end that the gauge members 33 can be held in upright position shown in Figure 1 to limit the downward cutting action of the saw, as the saw bar 2! rides the tops of these gauge members 33, as when the saw is cutting on an oblique as represented in Figure 2. However, whenthe rod 9 has been swung so that the hook I0 is engaging in the opening l6 of the plate l2, the cable is brought straight through the tool, that is transversely across the plate l2 and the gauge members 33 can be dropped as it is then desirable to cut square across the cable to completely sever the same.

Obviously, the tool can be used in various manners and on various occasions and while the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

In a cable cutting tool, an elongated handle, a plate mounted onone end of the handle crosswise thereof, a saw mounted on said plate for reciprocation in a plane at a right angle to the plane of the plate, and means to clamp a cable on said plate in different angular positions relative to the line of reciprocation of said saw comprising a rod extending longitudinally through said handle and through said plate and having a hooked end arching over the plate for straddling a cable to clamp the same to the plate, said rod being longitudinally movable toward and from 10 the plate, respectively, to move the hook into and from clamping relation to said plate and rotatable to swing the hook into different angular positions relative to the line of reciprocation of the saw, manipulative means to move said rod in one direction longitudinally and to rotate the same comprising a plunger endwise slidable and rotatable in the other end of the handle, spring means in said handle opposing movement of the rod in said one direction, and means to lock the hook to the plate in said different angular positions thereof against accidental rotation out of such positions.
