2 Claims.

' This invention relatesV to wire stretchers and splicers andits general object is to provide a device of that character that is. capable of use'with all kinds of wire, in stretching and holding the same taut and splicing the adjacent ends, in an easy and expeditious manner and with very little attention. K

A further object of the invention is to provide a wire stretcher and splicer that is light in Weight, yet isstrong and sturdy, is simple in construction, inexpensive to manufacture and extremely ecient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or correspo-nding parts throughout the several views, and in which:

Figure 1 is a side elevati-on of my device in use.

Figure 2 is a top plan view thereof.

Figure 3 is a view illustrating the manner of completing what is generally termed a telephone splice by my device.

Figure 4 is a View showing the completed telephone splice.

Figure 5 is an end View showing the wire receiving notch of my device.A

Figure 5 is a side elevation showing my device in use in making what is termed a loop splice.

Figure 7 is a top plan View of Figure 6.

Figure 8 is a View similar to Figure 3 but illustrates the use of the device in completing the loop splice.

Figure 9 is a View showing the completed loop splice.

Referring to the drawing in detail, it will be noted that the body of my device is shown as be-` ing formed from a single strip of metal that is looped midway its ends toV provide'what may be termed a yoke, and the body includes relatively narrow end portions indicated respectively by the reference numerals I and Z. The end portion I includes the loop which for distinction is indicated by thereference numeral 3, and the Yloop has arranged therein a slot li that follows the loop, as best shown in Figure 5 of the drawing.V

The parts of the strip that make up thev end portions are held in spaced relation through the instrumentality of collars 5 which are secured to the headed pins 6 that are xed to the parts, as best Vshown in Figures 2 and 3.

with registering openings arranged therein to rol l 1 Vtatably receive what may be termed a shaft 8, the

latter having a handle 9 formed thereon and the 5 Vshaft is held in the openings by a cotter pin or the like II). The shaft is provided with a bore II that extends transversely therethrough, for a purpose which will be presently apparent.

Mounted between the parts of the end portion 2 and for rotation upon one of the pins 6 are jaw members I2 and I3 that are arranged for pivotal movement and for cooperation with each other, for the purpose of setting up clamping 15 engagement with a strand of wire, as best shown in Figures l and 2. The jaw members are preferably of right angle formation and the jaw portions thereof are indicated by the reference numerals I4 and I5. 20

My tool is not only capable of stretching and splicing wire, but a number of diierent types of splices can be made therewith, and I have illustrated the manner of using the tool in making two well known splices, namely one 25 that is generally termed a telephone splice, and the other is termed a loop splice.

In making a telephone splice, one end of a strand of wire is disposed through the slot II and over and under the collars 5 of the end portion 30 I, as clearly shown in Figure l, and the end is then inserted through the opening of the shaft 8. For distinction, this end portion of the strand of wire is indicated by the letter A. The shaft is rotated through the instrumentality of 35 its handle for winding the portion A about the shaft, until it is taut. The end portion of the strand of wire B, which is to be spliced with the strand A, is inserted between the jaw portions I4 and I5, and thence extended, and coiled about 40 the strand A as at C. The strand B is removed from the jaw portions I4 and I5, and the tool is disposed at right angles with respect to the strands, as shown in Figure 3, and rotated in a manner to coil the strand A about the strand 45 B as at D, to complete the telephone splice, as shown in Figure 4.

In making the loop splice, the end portion of a strand E of wire is passed under the loop 3 and disposed under and over the collars 5, as well as 50 inserted in the bore of the shaft 3 in the same manner as above described. Half of the loop splice is made in the end of a strand F, and the loop thereof is inserted in the slot 4, as shown in Figure 6, then the tool is arranged at right 55 angles with respect to the strand E for moving the end portion of the strand E accordingly, as shown in Figure 8, and the remaining half of the loop splice is then made to complete the splice, as shown in Figure 9.

From the above description and disclosure in the drawing, it will be obvious that I provide a wire stretcher and splicer that can be used for making many well known splices in an easy and expeditious manner, and it permits the stretchf ing of long strands of wire, due to the fact that the shaft 8` can be used for wrapping a relatively great portion of a strand thereabout, and the portion that is Wrapped about the shaft can be used from time to time for repairing short breaks in the wire, as will be apparent.

It is thought from the foregoing description that the advantages and novel. features of my` invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of formation to provide a relatively large intermediate portion and end portions extending from the intermediate portion, a shaft journalled in the parts of the intermediate portion and bridging the same, said shaft having a bore transversely disposed therethrough to receive the end of a strand of wire so that the latter can be wrapped about the shaft, splicing means for the end portions and including collars disposed between the parts thereof, a pair of cooperating jaws pivotally mounted between the parts of one of the end portions to set up a clamping engagement with a strand of wire and the opposite end 10 portion being provided with a slot providing a Wire receiving and guiding means.

2. A wire stretcher and splicer comprising an elongated body formed from a single piece of ilat material. into substantially yoke like formation to provide a relatively large intermediate portion and end portions extending therefrom, a shaft journalled in the intermediate portion and bridging the parts thereof, said shaft having a bore' transversely arranged therethrough to receive the end of a strand of Wire, splicing means for the parts of each of the end portions and including collars acting as wire receiving means, right angled disposed Wire clampingr means including parallel arranged and cooperating jaws pivotally secured to one of the end portions, and the opposite end portion including a loop having a slot arranged therein to act as a Wirev receiving and guiding means.

EMIL DURR.
