Application May 11, 1956, Serial No. 584,245

2 Claims. (Cl. 30-91) This invention relates to the class of tools and more particularly to a novel cable slitter.

The primary object of the present invention resides in the provision of a cable slitter which is made of a nonmetallic substance and which is adapted to fit the hand of the user in a highly convenient and comfortable manner.

An additional object of the invention resides in the provision of a cable slitter which employs a deformable flap so as to enable pressure to be brought on a cable by merely squeezing the entire device. 1

One of the features of the invention lies in the pro vision of a cable slitter having a recess therein with means for holding the entire device in an assembled state holding a plurality of blades in the recess.

Still further objects and features of this invention reside in the provision of a tool of the class described which is simple in construction, efiicient in use, inexpensive to manufacture, which may be used to cut the outer covering of non-metallic sheet cable in a convenient manner.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this cable slitter, a preferred embodiment of which has been illustrated in the accompanying drawing, by way of ex ample only, wherein:

Figure 1 is a perspective view of the invention shown ready for use as a cable slitter;

Figure 2 is an elevational view of the invention with one part of the body removed and with the fasteners holding the parts of the body together being shown in section; and

Figure 3 is a sectional detailed view as taken along the plane of line 3-3 of Figure 1.

With continuing reference to the accompanying drawing wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates the cable slitter comprising the present invention. This device includes a body 12 which may be formed in two parts as at 14 and 16. The body is provided with an arcuate channel 18 therein adjacent the end 20 of the body 12 and extending the full length of the body.

Openings

22 and 24 are, of course, formed in the body with the opening 22 being of somewhat larger dimensions than the opening 24 and with the channel 18 extending substantially the full width of the body 12. The channel 18 is arcuate in shape and forms a flap 26 at the end 211) of the body with the flap 26 being deformable. Because of the shape of the channel 18 as well as the shape of the body, adjacent the opening 22 there is provided a thickened portion 28 which is movable with the deformable flap 26 and forms a part thereof yet which in itself is comparatively rigid.

The

body parts

14 and 16 are so shaped as to form recesses as at 32 and 34 for reception of a blade 36 such as a razor blade or the like. Further, the

recesses

32 and 34 may be of larger size for reception of a reinforc- 2,819,520 Patented Jan. 14, 1958 ing plate for rigidifying the blade 36. The blade 36 is so arranged that an edge 38 thereof will extend into the channel 18 so that upon application of pressure on the flap 26 by gripping the entire body, upon sliding the entire body along the cable the edge 38 of the razor blade cuts the outer covering of the cable.

Holding the blade 36 in position are a pair of bolts db and 42 which are preferably countersunk. If the bolts as at d-tl and 42 are suitably countersunk, and with the body 12 being formed of a suitably non-metallic electrically insulative material, the entire device may be electrically insulative.

in addition to the

recesses

32 and 34 being formed in the body, another recess 44 may be formed therein for reception of a plurality of spare blades 46 which may be held in place by fastener 43 which also may be countersunk as desired. Oppositely disposed to the. end 20 of the body is the end 50 of the body which is preferably corrugated to form finger-grips as at 52, 54, etc. These provide means whereby the entire device may be conveniently grasped without slipping.

In practice, the cable is inserted in the channel 18 and pressure is applied on the body by squeezing the hand. This pushes the flap 26 towards the other portions of the body. When this is done, the cable is pressed against the edge 3? of the razor blade 36 and then by sliding the device along the cable to be slitted, the razor blade cuts the outer covering of the cable.

From the foregoing, the construction and. operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A cable slitter comprising a body, said body having a channel therein adjacent one end thereof with said channel extending the full length of said body and extending substantially the full width thereof, said channel being arcuate in shape and forming a deformable flap at said one end of said body, the other end of said body being corrugated and forming finger-grips, said body being formed of a non-metallic material, a blade disposed in said body and having a cutting edge thereof extending into said channel.

2. A cable slitter comprising a body, said body having a channel therein adjacent one end thereof with said channel extending the full length of said body and extending substantially the full width thereof, said channel being arcuate in shape and forming a deformable flap at said one end of said body, the other end of said body being corrugated and forming finger-grips, said body be ing formed of a non-metallic material, said body being formed in two parts, a blade disposed between said parts, and means securing said parts together, said means securing said blade in said body with an edge thereof extending into said channel oppositely disposed to said deformable flap.
