JAMES W. BARTON, OF PEQUOT, MINNESOTA.

WIRE-SPLICING TOOL.

To all whom it may concern:

Be it lmown that I, JAMES W. BARTON, citizen of the United States, residing at Pequot, in the county of Crow Wing and State of Minnesota, have invented certain new and useful Improvements in VVire- Splicing Tools, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved wire splicing tool and has for its primary object to produce a device of this character which is simple and durable in its construction, and whereby the ends of a broken fence wire may be readily drawn together and spliced.

Another object of the invention resides in the provision of a rack bar, a member mounted upon said rack bar for sliding movement and provided with wire clamping means, said rack bar having one of its ends constructed to receive a loop formed on one end of the wire and means mounted upon said sliding member for engagement with the teeth of the rack bar to slide said member whereby the wire ends are drawn past each other.

A still further object of the invention is to produce a wire splicing tool which is light in weight and can therefore be easily and quickly manipulated by the operator, said tool being capable of manufacture at compara-tively small cost.

ith the above and other objects in View as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrange ments of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a top plan view of a wire splicing tool embodying the preferred construction of my invention; Fig. 2 is a side elevation thereof; Fig. 3 is a section taken on the line 33 of Fig. 1; and Fig. 1 is a detail perspective view of the slide bar.

Referring in detail to the drawing, 5 designates the body bar of the tool which is of rectangular form and is provided upon its upper and lower edges with the notches 6, the notches on the respective edges of the bar alternating with each other. To one end of this body bar, a suitable bearing Specification of Letters Patent.

Application filed April 26, 1913.

Patented Apr. 20, 1915. Serial No. 763,854.

block 7 is secured or may be integrally formed therewith and is adapted to be en gaged by the post or other stationary object or against the body of the operator. The other end of the body bar has a head 8 integrally formed thereon, and this head is provided with an open ended slot 9 forming the spaced longitudinally extending arms 10. Each of these arms is provided with a notch 11, the purpose of which will be more fully pointed out in the following description.

A slide bar 12 is longitudinally movable upon the body bar. This slide bar consists of the end blocks 13 which are integrally connected by means of the longitudinal bar 14. These blocks are also formed with rectangular openings 15 to receive the body bar 5, said bar and the connecting bar 1 1 being disposed in spaced parallel relation. The upper and lower ends of each of the blocks 13 are beveled or inclined, in relatively opposite directions as indicated at 16. The block 13 which is located nearest to the head 8 on the end of the body bar is provided uponone of its side faces with a shoulder 17, and upon said block a cam 18 is pivotally mounted, said cam being adapted for gripping engagement with one of the wire ends W to securely hold the same upon the shoulder 17.

The operating lever 19 is provided upon one end with spaced arms 20 one of which extends between the body bar 5 and the slide bar 12, said arm being fulcrumed upon the bar 14 intermediate of its ends as indicated at 21. The other arm of the operating lever is disposed across the outer face of the body bar 5. Between these arms of the operating lever, the dogs 22 are said dogs being located upon opposite sides ofthe body bar 5 and adapted for engagement with the respective notched edges thereof. These dogs at one of their ends are reduced in width for engagement with the beveled faces 16 of one of the blocks 13, of the member 12, to alternately force the opposite ends of said dogs into engagement with the notched edges of the rack bar as the lever 19 is manipulated.

In the use of my improved tool, the same is arranged, as shown in Fig. 1, with the lever 19 extending horizontally toward the operator, and a loop L is provided in the end of one of the wire strands W and engaged in the notches 11 provided upon the end of the body bar 5. The other wire in pivotally mounted,

dicated at W, is passed under and through 'the loop L upwardly between the arms 10 and longitudinally over the bar 5. The end of this latter wire is secured to the slide bar 12 by means of the cam 18. The operator notvmanipulates the lever 19 to alternately engage the dogs thereon with the respective notched edges of the body bar, whereby the slide bar 12 is moved longitudinally upon the bar 5 away from the head 8, thus stretching the ends of the wire in 0-pposite directions and drawing the same past each other. It is, of course understood that the block 7 on the end of the body bar 5 is engaged with a post or with the body of the operator. The operator grasps the bar 5 in one hand and with the other operates the lever 19. After the wire is sufficiently tight, the operator swings the tool upon the loop L so as to bend the wire W around said loop. The operator now grasps the wire W and loosens the clamp 18. The end of the wire is then twisted upon itself close to the loop L so that the wires'are properly connected together and a tight connection between the same maintained. In this manner, it will be seen that the wires may be quickly stretched and spliced together.

By mounting the cam lever 18 upon the slide bar 12 with respect to the slot 9 in the end of the body bar as illustrated in the drawing, it will be appreciated that the wire W may be very easily and quickly threaded through said slot and secured to the head of the slide bar by said cam. This arrangement of the lever 18 and slot 9 also affords a direct pull upon the wire when the same is stretched.

From the foregoing, it is thought that the construction and manner of operation of my improved wire splicing tool will be clearly and fully understood. By means of the same, the ends of a broken wire may be very easily, quickly and securely spliced together.

Owing to the extremely simple construction of the invention, it will be appreciated that the same is very strong anddurable in bar provided along its opposite edges with alternating notches andat each end with a rigid head, one of which is longitudinally and transversely slotted,-a slide bar provided at its ends with channeled heads to receive the body-bar, a wire gripping camcarried by one of the heads, an operating lever havlng one end bifurcated to provide arms to straddle the body-bar, a pivot connecting the arms and the body-bar, and dogs pivoted between the lever arms and arranged to engage the notches in the body-bar.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses. I

JAMES W. BARTON. Witnesses:
