CABLE AND WIRE STRIPPER Filed May 3, 1946 Inventor Patented Mar. 28, 1950 UNITED STATES PATENT. OFFICE CABLE AND WIRE STRIPPER Henry E. Charles, Pittsburg, Calif.
Application May 3, 1946, Serial No. 667,085
The present invention relates to certain new and-useful improvements in hand tools and implements such as are employed for cutting and slitting insulation on wires in a manner to permit the insulation to be peeled or stripped from said Wires.
An object of the invention is to provide a simple and reliable tool which is economical and handy and by means of which the insulation on a wire may be effectively and conveniently cut and then stripped from the end portion of the wire or from any desired intermediate portion of said wire.
A further object is to provide a tool wherein the insulation cutting members are so arranged and such as to permit the insulation to be split longitudinally in relation to the longitudinal axis of the wire in a manner to facilitate ready removal of the insulation and to promote other advantages desirable to users in this line of endeavor.
More specifically, in carrying out my ideas, I provide a plurality of standardized, interchangeable attachments and these are expressly constructed and adapted to be fitted removably on existing jaw portions of a type of pliers vice wrench which is now sold on the open market.
Other objects, features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawing, wherein like numerals are employed to designate like parts throughout the views:
Figure 1 is a side elevational view of a marketed type of wrench, this shOWing one set of improved insulation cutting attachments detachably fastened on the stock jaws of said pliers vise.
Figure 2 is a front or outer end elevation, that is, an end view of Figure 1 observing the same in a direction from left to right.
Figure 3 is a top plan view.
Figure 4 is a detail end elevation of a modified type of attachment such as is sometimes used.
Figure 5 is a side view of the same, that is, a view observing Figure 4 in a direction from right to left;
Figure 6 is a further modification showing a different type of attachment used in conjunction with the companion attachment disclosed in attachment seen in Figure 6.
Figure 9. is a side View of two of the attachments (see' Figures 1 to 3) poised and ready to 1 Claim; (Cl. 81-181) 2 Y be slipped into positions on the jaws of the pliers vise.
It is perhaps advisable, as an introductory measure, to call attention again to the fact that I do not claim to have invented the illustrated wrench or so-called pliers vise but rather the ready-to-use attachments, said attachments being such as to coordinate and combine their facilities and functions with those of the wrench to thus provide a complete working tool for cut ting insulation from wires. To this end, the wrench is denoted by the reference character The handle section B is provided with a' comple mental squeeze type handle member C suitably pivoted in place and operating a rocking jaw member D. This member D is provided with-"a workengaging jaw E which is opposed to a slim lar jaw F on the jaw portion G, as shown in Figure 9. All of the attachments shownin-the remaining figures (4. to 8 inclusive) are applic' able to the jaws E and F and associated jaw portions. I
Reference being had to Figures 1, 2, 3 and 9; it will be seen that the companion attachments I0 and H are constructed and mated for use in co-acting pair relationship, as illustrated; In Figure 2, the adapter member of attachment I0 is in the form of a sleeve l2 having on one'side an outstanding stub-axle l3 carrying a bearing M with a cutting disk l5 thereon. The sleeve is provided on the other side with a set-screw I6 and is fashioned to slip endwise on and over the jaw portion G. Interiorly the sleeve has a keyway or groove I! to accommodate and take care of the projecting jaw F.
The unit or attachment ll also includes an adapter sleeve I8 with a single keying groove IS in one side wall. Also, there is a set-screw 20 on one side of the sleeve and grooved rollers 2| on the opposite side. Said rollers 2i are arranged in alignment with each other and they have their grooved peripheral portions positioned for accommodation of the wire to be cut and later stripped (not shown). In cross sectional shapes and dimensions, the respective adapter sleeves of attachments i8 and II will vary to conform to and snugly lit the parts G and D with which they cooperate. With the attachments in place, they occupy the positions seen in Figures 1 to 3, the cutting disk l5 being properly located in respect to the rollers 2i to permit the insulation (not shown) to be cut and then peeled and stripped off.
The attachment denoted by the numeral 22 in Figure 4 comprises an adapter sleeve 23 with a insulation in an obvious manner.
set-screw 24 and keying grooves 25. There is also a grooved spacing collar 25 on one side of the sleeve and this is fashionable to accommodate and mount a cutting blade 27, the latter being held in place by a screw fastener 28.
The other and remaining attachment is denoted by the numeral 29, Fig. 6 and this also comprises an adapter sleeve 39 with a set-screw 3|, said sleeve having on one side an outstand ing small shelf or flange 32 carrying a block 33 held in place by a fastener 35, said block having wire seating and retaining prongs 35 arranged on the four corners thereof.
It will be clear from the foregoing drawings and description that the attachments, Ill and H onthe one hand and 22 and 29'on the other hand, are in two distinct and paired sets or "groups. The first'p-air of attachments is covered in Figures 1, 2, 3 and 9, as before indicated. Here the attachments have coacting rollable parts It and 2| to properly grip the cable and insulation covering thereon for purposes of stripping the The attachments l0 and II of the stated figures may be removed and the two attachments, shown at 222 and 29 in Figures 4 and 6, may be substituted.
Actually then, there are simply two sets or pairs of attachments, the type or form shown in Figures 1, 2, 3 and the other type, the components of which are best shown in Figures 4 andfi. What is also clear, the last named pair of attachments is shown in difierent positions in Figures 4. to 8 inclusive.
.It is to be noted in connection with all forms of the invention that common characteristics pertain, in each instance, to an adapter sleeve which slips over the jaw-carrying portion of the pliers vise or wrench and has a cross-sectional shape to correspond to such jaw-portion, and also a cross-sectional shape to provide a keying groove or grooves for reception of the projecting edge or ribportions 0f the jaw faces E and F. In addition, there is a set-screw provided on the sleeve and on one side of the sleeve there is an onset instrument or device to form either a cutting ,knife (see Figure 1), a cutting disk (see Figures .1 to 3), or feeding rollers (see Figures 1 to 3) or a special anvil block, the latter as shown in Figures 6 to 8.
A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed.
Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.
I claim:
Attachment means for a pliers vise of the class shown and described comprising in combination, an adapter sleeve for detachable application to a predetermined part of said vise, said sleeve being provided on one side with a fastening screw and being provided on an opposite side with a right angular-1y disposed outstanding flange, an anvil forming block .turnably and detachably mounted on said flange, said block being provided on its normally upward face with four corner projections to hold and guide a length of insulated wire which is adapted to be stripped, a second adapter sleeve having means on one side for fastening the sleeve in place on a coacting part of the pliers vise and provided on an opposite side with a spacing collar, and an insulation cutting and slitting blade removably mounted on said spacing collar.
HENRY E. CHARLES.
