COMBINED SLIDABLE JAW WIRE CUTTING AND HOLDING TOOL 3 Claims.

This invention relates generally to combination cutting and holding tools and more particularly to combination cutting and holding tools for the cutting and assembly and disas-` sembly of small electrical wires in remote and inaccessible places where the iingers cannot be used.

In the assembly and disassembly of small wires, particularly in a cluster of wires used in a radio set, it is impossible to hold many of the wires with the fingers and it has heretofore required considerable time and expense in attempting to utilize makeshift tools forl holding the small wires. This is particularly true when it is desired to repair a radio set where it is necessary to assemble a loose connection in the center of a cluster of wires or otherY impedimenta. Like wise, cutting a wire in a remote position has heretofore been a very tedious and time con suming job.

It is, accordingly, an object'of my invention to provide a combination cutting and holding tool for electrical wires and the like, which is simple in'construction, economical in cost, economical in manufacture, and efficient in. operation.

Another object of my invention is to provide a combination cutting and holding tool for electric wires. and the like forl cutting and for assembling and. disassemblingl wires in remote and inaccessible places.

Another object of my invention is to provide a combination cutting and' holding tool for electrical wires and the like wherein theY head of the tool may be rotated through a 360 angle.

Another object of my invention is to provide F a combination cutting and holding tool. wherein the cutting or` holding member is'rotatable with the head. thereof.

Another object ofv my invention is to provide a combination cutting and' holding tool. for electrical wires and the like wherein adjustments may be madel to accommodate. different sizes of wire.

Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, in which f Fig. l is a vertical sectional` View of one em-- bodiment of my novel combination cutting'and holding tool;`

Fig. 2 is a fragmentary side elevational view of the head of the tool shown in Fig. l;

Fig. 3 is a vertical sectional View of another embodiment of my novel. combination cutting and holding tool; Y

Fig. 4 is a fragmentary side elevational view of the central portion of tool shown in Fig. 3; and

Fig. 5 is a fragmentary view of a holding member for use in the tool shown in Fig. 3.

Referring now to the drawings, Figs. 1 and 2 show a stationary base member having a handle 2, a center bore 3, a threaded counterbore 4, and a cut-away portion 5 forming parallel ears 6 between which is disposed a bell crank member 1 having a handle 8, an outwardly extending portion 9 and an aperture II] for receiving a pin II which is journalled in the ears 6. A stop pin I2 engages the portion 9 of the bell crank 1 to limit the movement thereof in one direction. An upwardly extending sleeve 'I4 has a threaded portion I5 for threadably engaging the threaded counterbore 4 of the member` I. A head I8 has an enlarged arcuate shaped portion`l1 which engages the inwardly turned, arcuate shaped upper end I8 of the sleeve I4. Head I6 is thus freely rotatable on the sleeve I4. The extension I6 has a cutaway portion I9 and a bore 2B for receiving a cutting member 22 which extends axially of the sleeve I4. The cutaway portion I9 of the extension I6 forms an abutting surface 23 for engaging the inverted V- shaped cutting end 24 of the cutting member 22. The cutting member 22 may be replacedby a blunt ended holding member 10 similar to the one shown in Fig. 5. The cutting member 22 has a flattened surface 5I] for engagement with the flat surface 5I so that it rotates with the head I6 and is always in a cutting position. The lower end of the cutting member 22 is threaded at 25 to threadably engage the threaded recess 26 in cylindrical member 21 which slides in the lower end of the sleeve I4 and the bore 3 of the base member I. The cylindrical member 21 engages the end 9 of the bell crank 1 and is adapted to be moved upwardly by it. A coil spring 28 is disposed between enlarged end I1 of the head I6 and the cylindrical member 21 to urge the cutting end 24 of the member 22 away from the abutting surface 23 of the head I6 and it also urges the enlarged arcuate end I1 of head I6 against the inwardly turnedv upper end I3 of the sleeve I4.

By pressing inwardly on the handle 8 of the bell crank 1, the end 9 of the bell crank 1 rises and moves the cylindrical member 21 and cutting member 22 upwardly against the force of the spring 2S whereby the upper end 24 of the cutting member 22 moves into engagement with the abutting surface 23 to cut or hold a wirev held in close proximity thereto. The upper end 24 of the member 22 may be blunt or any other form for` holding a Wire. My novel tool will be preferably provided with a holding member and a cutting member 22 interchangeable with each other.

My novel tool has the head thereof of a comparatively small diameter and extending axially outwardly from a sleeve so that it may be extended into a cluster of wires to engage a wire within the cluster. It has been found that if the head I6 is not rotatable and the handles 2 and 8 are crosswise of the cluster of wires, it is impossible to secure the wire between the abutting surface 23 of the head I6 and the end 24 of the tool member 22. I have provided a head which is freely rotatable in the end of the sleeve I4 so that it can be placed in the best position for it to be passed into a cluster of wires with the handles 2 and 8 parallel with the wires or in any other desired position.

In Figs. 3 and 4, I show another form 0f my invention in which a tubular member 30 has a handle portion 3l, a longitudinally extending slot 32, and an internally threaded portion 33 for threadably engaging the enlarged threaded end 34 of a head 35. The head 35 has a bore 36 for receiving' a cutting member 31 flattened at 4| which extends axially of the tubular member 30 and seats in recess 38 in a cylindrical member 39 movable in the lower portion of the tubular member 30. The head 35 has a cutaway portion 40 forming an abuting surface 42 for engaging the inverted V-shaped cutting end 43 of the cutting member 3l. The flattened surface 4I of cutting member 31 engages flat surface 60 of the head 35 so that the cutting member 3'! rotates with the head 35 to be always in a cutting position.Y Bell crank member 44 has a handle 45 and an inwardly extending portion 46 for engaging the cylindrical member 39, the portion 46 of the bell crank 44 extending through the longitudinally extending slot 32 in the member 3D. The bell crank 44 is pivoted on a pin 41 secured by a clamp 48 surf' A spring 49 rounding the tubular member 30. is disposed between the head 35 and the cylindrical member 39.

By pressing inwardly on the handle 45 of the bell crank 44, the end 46 of the bell crank 44 rises thereby moving the cylindrical member 39 and holding member 31 upwardly, the upper end 43 of the holding member 31 thereby moving into engagement with the abutting surface 42 of the extension 35 and against the force of the spring 49 between the extension 35 and the cylindrical member 59. By disposing a wire adjacent the abutting surface 42 of the extension 35 and pulling the handle 45 inwardly it will be engaged by the cutting end 43 of the member 31. Cutting member 31 may be replaced by a holding member I shown in Fig. 5.

It will be evident that my novel combined cutting and holding device is such that the head or extension end may be rotated to accommodate any position of wire especially when the wire is so remote that the handle portions of the holding tool cannot be rotated. Furthermore, the head 35 in Figs. 3 and 4 may be rotated to increase or decrease the distance between the abutting surface 42 and the end of the cutting member 37 or holding member 5G to accommodate different sizes of wire. It is not absolutely necessary that the head of myonovel tool be rotatable or threadable in that the head end of my novel tool may be built as part of the sleeve, although I have found it preferable to be able to rotate the head I6 to enable one to get at remote wires in various positions.

It will accordingly be seen that I have provided a novel adjustable combined cutting and holding tool which is easy to operate, which may be of different lengths so that the remotest wire may be cut or held therewith, and my novel tool is easily dissassembled to effect any repairs which are necessary or to interchange the cutting and holding members.

Various changes may be made in the specific embodiment of my invention without departing from the spirit thereof or from the scope of the appended claims.
