roor. FOR WRAPPING WIRE.

Application filed November 28, 1923. Serial No. 677,508.

This invention relates to an improvement in tools for wrapping wire, and is especially designed for use in wrapping wire in forming wire splices or wire joints.

.The object of the invention is to provide a tool of this character which is in itself simple and durable in construction, easy and comparatively inexpensive to. manufacture and which greatly simplifies and facilitates the various operations incident to the formation of the wire joint or splicers and which also carries outits functions in a more effective and efiicient manner than any of the tools heretofore proposed.

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will. be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification and in which: t

Figure 1 is a perspective view, showing the improved tool in use in wrapping a wire during the formation of a wire joint or splice; I

Figure 2 is a top plan View ofthe tool shown in Figure 1;

Figure 8 is a bottom-plan View thereof; Figure 4 is a view thereof in side elevation; and 4 Figure 5 is a detail View in section on line 5 5 of Figure 2.

1 are substantially circular in cross section.

At the points where these fingers 14 join the body portion 13 they are enlarged so as to be substantially ellipticalin cross section.

Referring to the drawings, the numeral.

At the tipsor extremities of these fingers 14 they are extended toward each other, as at 15, so that-the fingers 14 present c'oncaved confronting wire-engaging faces 16. The body portion 13v of the working head is forn-ied with a radial slot 17-which extends from the periphery ofthe body portion at a point between two of thefingers 14 in through the body portion-to a point slightly beyond the center thereof, as clearly shown in Figure 2. This slot 17-enables the working head to be mounted on either of the main "strands S of the wires to be spliced and to be rotated t'herearoiind while one of the wire engaging faces16 of the fingers 14 is engaged with the end W of. the wire to be wrapped around the main strand S on which the tool is mounted.

r A bar 20 is pivotally connected to the handle member 10, as at 21. This bar is in length slightly less than the combined length of the member and the working head 12.

member and thefport-ion thereof which underlies thehead 12 is slightly enlarged with respect to the main portion of the bar though somewhat smaller than the working head 12. --The surfaces of the handle member strengthen the bar 20 and to facilitate manipulation of this bar. The port-ion of the bar 20 which underlies or which is opposed to the handle member 10'constitutes a complementary handle member. The portion of this bar 20 which underlies or is opposed to the working head 12 is slotted, as at 23, to provide a movable jaw face 24. Around this jaw face 24 the bar 20 is enlarged orrein- Y forced, as at 25. On the under side of the working head 12 a fixed jaw 26 is formed and is arranged to co-oper'ate with the jaw .76 In width it .is coextensive with the handle face 24 of the bar 20. The end portion 28 e of the bar 20 which lies on one side of the slot 23 is adapted to extend across the under side of the slot 17 of the working head12 and serves to prevent the accidental displacement of the Working head fromt-he main strand of wire on which it is mounted during the coiling or wrapping operation of the wire V, the portion 28 constituting a latch for this purpose. The fixed jaw 26 coacts with the movable jaw face 24 to pre vent or minimize the tendency of the tool to work axially along the strand S on which it is mounted since this jaw and jaw face frictionally engage the strand for such purpose.

By constructing the wire engaging fingers as above described and by forming the confronting wire engaging iaces 16 concave it is possible to use a single working head 12 and a single set of fingers 14: to wrap or coil both wrapping wires about the main strand and to wrap or coil these wrapping wires in eitherdirection. To reverse the direction of wrapping it is not necessary to remove the tool from the main strand wire on which it is mounted. 7 These advantages are had in a simple reliable tool where at the same time accidental displacement of the working head laterally from the main strand is prevented. In other words the bar'20 with its slot 23 and latch 28 prevents the working head from slipping off the strand wire S as it would were the slots 17 open and unobstructed. A further and important advantage is had by the provision of the aw 26 and jaw face 24 which minimizes the tendency of the tool to work axially along the strand wire S on which it is mounted. The elements which serves to prevent accidental displacement laterally and axially are controlled by the grip of the operator which must be exerted to actuate the tool. The tool may be readily dismounted from the strand of wire after the wrapping or splicing has been completed by swinging the bar 20 and the handle mem-- ber '10 about the pivot 21. Such swinging motion may be readily imparted to these elements by virtue of the ribs 11 and 22.

In'order to prevent the bar 20 from swinging past the handle member 10 in one direction the bar 20 may be provided with a stop with the first-mentioned head and having a slot at substantially right angles to the slot in the first-mentioned head, the provision of the slot in the second-mentioned head forming a latch adapted to be disposed transf versely across the outer free end of the firstmentioned slot, said latch being adapted to engage the wire for releasably forcing the same when the handles are in alignment in frictional contact with the inner end of the first-mentioned slot.

2. A tool for use in wrapping wire comprising a handle member having a working head, provided with lateral fingers for engaging the wrapping wire, said fingers being disposed in spaced. relation along the periphery of the head, the head being provided witha radial slot extendinginwardly beyond the center of the head, a second handle pivotally mounted on the firstn'ientioned handle and having a head in close contact with the first-mentioned slot and pro vided with a slot at substantially right angles to the slot in the first-mentioned head, said slot providing a latch at the outer end of the second-mentioned head, an cdgeof the slot in the first-mentioned head providing a aw face, a jaw on the first-mentionedhead and co-operating with the jaw face of the second head to minimize the tendency of the tool to work axially along the strand of wire when the handles are in alignment.
