8 Claims.

An object of this invention is to provide a wire working tool of this kind which is so constructed that a single or a plurality of strands of wire may be securely clamped within the device-so that the wire can'be pulled or otherwise worked, such as twisting or the like. V

Another object. of this invention is to provide an exceedingly simple wire twisting device which is so constructed that the wire will be firmly held within the device while a portion of the device may be rotated so as to twist a plurality of 5 strands of wire together without requiring th ends of the wire to be relatively long;

A further object of this invention is to provide a device of this kind which can be used for either working wire, rods, or other elongated articles. The above and various'other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, thesame being illustrated in 2.5 the accompanying drawing wherein:-

Figure 1 is a detail sideqelevation of a device constructed according to the preferred. embodiment of thisinvention.

Figure 2 is a longitudinal section partly in 30 detail of the device showing a pair of wire strands secured therein.

' Figure'3 is a sectional view taken on the line 33 of Figure 1.

Referring to the drawing wherein like numerals 85 of reference designate corresponding parts 45 vided with a crank handle 14 which is suitably secured to the inner end of the shaft and preferably, a washer or anti-friction element 15 is interposed between the hub of the handle 14 and the inner end of the housing 10.

A head 16 is carried by the outer end of the shaft 12, and this head 16 has an opening 17 extending transversely therethrough within which a wire clamping member, generally designated as 18, is rotatable. This wire clamping member ,55 18 comprises a transversely extending shaft 19 arm 11.

provided on the periphery thereof with a recess 20which is disposed in alinement with the bore 13 so that when the shaft 19 is rotated to a position where the recess 20 registerswith the opening 13, a wire or rod may be readily passed into .the bore 13.

A lever 21 is carried by one end of the shaft 19, and this lever 21 has a flange 22 integral therewith which is adapted to engage one side of the head 16 for holding the shaft 19 against movement in one direction through the head 16. A cotter pin 23 extends transversely through the opposite end of the shaft 19 and engages against a washer 24 and coacts with the flange 22 to holdthe shaft 19 against lateral movement in the head 16 while permitting rotary movement.

A lug 25 provided with a hole 26 is carried by the shaft 19 and preferably this lug 25 is integral with the shaft 19 and with the lever 21 and the flange 22. This lug 25 with the hole 26 provides a means "whereby additional leverage may be placed-on the shaft 19 so as to more tightly clamp a wire within-the head 16. Preferably, the head 16 has a recess 27. within which the wire is adapted to be forced upon turning of the clamping member 18 in the head 16. A stop lug 28 is carried by the lever 21 and is adapted to engage a fixed lug 29 carried by the head 16 so as to stop the rotation of the shaft 19 when it is turned into wire receiving position. The head 16 is provided on one side thereof with a pair of claws 30, which claws provide means whereby the wire may be pulled by disposing the wire between the claws 30 and using the outer end of the arm 11 as a fulcrum and rocking the device on this In the use and operation of this wire pulling and twisting device, the wire W is passed through the bore 13 after the lever 21 has been rocked to inoperative position or the position shown in Figure 1. This lever 21 can then be rocked forwardly or outwardly toward the outer end of the head 16 and if the wire or other article disposed in the bore 13 is relatively stiff and will not readily be forced into the recess 27, a rod (not shown) may be passed through the opening 26 of the lug 25 and additional leverage applied to the clamping member 18. If it is desired to twist the wire W after the clamping member 18 has been turned to clamping position, the casing 10 may be grasped in the hand and the crank handle 14 then turned in the desired direction. During this operation, the arm 11 will also act as a guard so as to prevent the claws 30 from injuring the hand of the operator.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is:-

1. A device as set forth comprising a casing, a shaft journaled in the casing having a bore therethrough, a crank handle secured to one end of the shaft, a head on the other end of the shaft having a bore alining with the bore in the shaft, and means carried by the head for reducing the bore in the head at one point and thereby binding an article in the bore of the head.

2. A device as set forth comprising a casing, a shaft journaled in the casing, a crank handle secured to one end of the shaft, a head on the other end of the shaft, said shaft and head having a bore therethrough to receive a portion of an article to be twisted or clamped, and means extending transversely through the head for binding an article disposed in the bore of the head.

3. A device as set forth comprising a casing, a shaft journaled in the casing, a crank handle secured to one end of the shaft, a head on the other end of the shaft, said head and shaft having a bore therethrough, a transversely extending shaft carried by the head, said latter shaft having a recessed portion adapted to register with the bore in the head upon rotation of the latter shaft to inoperative position, and an operating lever carried by one end of said latter shaft.

4. A device as set forth comprising a casing, a shaft journaled in the casing, a crank handle secured to one end of the shaft, a head on the other end of the shaft, said head and shaft having a bore therethrough, a second shaft extending transversely through the head and partially intersecting the bore through the head, said second shaft having a recessed peripheral portion whereby upon turning of said second shaft toinoperative position, an article may be freely passed into the bore of the head, an operating lever carried by one end of said second shaft, and coacting means carried by the lever and the head to limit the rotation of the second shaft.

5.
