2 Claims.

This invention relates to a tool for repairing and installing wire fencing and is an improvement upon the fence tool disclosed in my U. S. Letters Patent No. 2,158,128.

It is an object of my present invention to provide a simplified and improved tool adapted to splice, stretch or take up slack in wire fencing of all types.

More specifically, it is an object to provide a multi-purpose fence tool of the general structure disclosed in my herein identified patent, but wherein certain advantages in the cost of manufacture and the cooperation of the wire engaging parts, are accomplished.

Another object is the provision of an improved fence tool utilizing a minimum amount of metal and thereby lessening production costs as well as the weight of the device, but constructed nevertheless, to give the maximum rigidity and leverage action required, as well as afllcient cooperative relationship between the adjustable and wire-engaging parts.

These and other objects and advantages of my invention will be more apparent from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same parts throughout the several views and in which- I Fig. l is a perspective view showing the application of my improved tool in taking up slack in a fence wire at both sides of the post;

Fig. 2 is a side elevation illustrating the use of my tool for stretching a wire;

Fig. 3 is a perspective view showing the beginning of a splicing operation in broken fence wire;

Fig. 4 is a view showing my tool used in a second or twisting operation in splicing;

Fig. 5 is a top plan view of my improved tool with the grab hooks attached to the slide block;

Fig. 6 is a side elevation ofthe same;

Fig. '7 is a bottom plan view of the same;

Fig. 8 is a perspective. view of a somewhat different and somewhat more costly embodiment of my invention;

Fig. 9. is a perspective view of the. slide. block and grab hook of the second embodiment, detached; and

Fig. 10 is a top plan view of the. outer portion of the lever bar with the lock arm fulcrumed thereto, in post-engagement position.

Referring first to the embodimentof' my invention illustrated in Figs. 1 to Tinclusive, I provide an elongated, substantially straight lever bar designated as. an entirety by the letter L, comprising, as shown, a heavy bent metal strap or sheathmg I land an elongated wooden handle and core 2 to the medial and outer portion of which the elongated U-shaped strap l i is secured by suitable means such as screws i3. The stem portions of the bent strap I! lay flat against opposite longitudinal edges of the core and handle member l2 and one of the stem portions thereof, as shown, (the upper) is straight and has a smooth exterior guiding surface for reception of a slide block. The opposite stem of the narrow U strap H is provided throughout the greater part of its length, with a series of longitudinally spaced, retaining shoulders Ha as shown, being in the form of corrugations for engagement with an edge of an adjustable slide block it. Strap H, at its forward end is bent in V-shape to provide an edge or post-engaging element i lb.

Slide block it may be in the form of a metal casting or a heavy looped rod shaped to loosely surround the medial portion of the lever bar with adequate clearance in its longitudinal dimensions to permit ready sliding adjustment to be made when the block I4 is disposed perpendicularly to the center line of the lever bar. The block on its inner periphery, is provided with an edge or edges defining a shoulder for retaining engagement with the retaining shoulders or corrugations Ila of the strap. The slide block M carries a wire retaining hook Ma, the outer end of which is directed rearwardlyof the lever bar for connection with the loop or enlargement of a fencing wire.

In cooperation with the slide block Hi for certain operations of my fence tool, I provide a pair of wire engaging grab hooks l5, pivoted by eyes 15a to an attachment plate [6 which is provided with an enlarged attachment aperture ifia adapted to be slipped over the hook Ma. The grab hooks 15, when used, extend forwardly at the two sides of lever bar -L and have wire-engaging hooks Nib, at' their outer ends for engagement with fence wire.

A combination lock arm and tightener ii is fulcrumed adjacent the forward end of lever bar [2, preferably being pivotally mounted upon an upstanding metal lug l8 which is welded or otherwise rigidly afiixed to the upper stem portion of metal strap H at a point a few inches rearwardly of the tip or post-engaging element Nb of the strap. As shown, lock arm I! comprises a bent, substantially rigid rod having a loop portion fulcrumed by a rivet or other pivot means Him to the lug l8 and having an outer extremity Ila which is preferably edged. or sharpened to slightly penetrate a wooden post. The lock arm Operations In Fig. 1 the use of my tool in taking up slack, at both sides of a fence post, without removal of the staples, is illustrated. Here the grab hooks l are utilized by attachment of the plate 16 with the hook Ma of the slide block. Slide block is properly adjusted adjacent the forward portion of the lever bar; the post-engaging point Hb' is thrust against the face of the post and the two hooks [5b are engaged with the fence wire at opposite sides of the post and the lever is then swung downwardly, tensioning the wire and wrapping the same slightly about the post, away from the stapled portion, in both directions. The lock arm I! is then swung from the dotted line position of Fig. 1 into locked position, as shown by the full lines, with its edged outer end engaging the post an inch or two above the point I lb of the lever .bar. Thereafter, a tie wire T may be applied by twisting the ends thereof, tightly about the fence wire at the sides of the post. The hands are free to perform this twisting operation since the tool is locked in the position indicated in Fig. 1. The tool is removed with the slack of the fence wire taken up and it will be noted, the staples need not be removed for this operation.

In Fig. 2, with the grab hooks removed, my device is employed for stretching a wire in installing a fence or replacing a wire. Here a loop is made in the end of the fencewire and is connected with the hook Ida of the slide block and the post-engaging element lib is thrust against the side of the post and lever force is transmitted, substantially in the line of the staples so that the staples will not be ripped out but may be slightly loosened in the operation, or if new fencing wire is being installed, may be driven after the wire is tensioned. Stretching is applied by swinging the handle of the lever bar downwardly whereafter the locking arm I! may be swung forwardly to engage the post and secure the device with the wire caught. Thereafter, both hands are free to staple or tighten the staples on the post.

In Figs. 3 and 4, the use of my fence tool for a splicing operation is illustrated. Where a fence wire is broken, it is usually necessary to add a short extra section S as shown in Fig. 3, in order that the ends to be joined, may be overlapped. The slide block [4 is adjusted on the bar L while the wire is slack and loops on the end of the two wires to be joined, are engaged by the hook Ma and the hook l'lb respectively, as shown in Fig. 3. The lever bar grasped by its ends with two hands, is then swung or twisted as indicated by the arrows in Figs. 3 and 4 to tension the two ends of wire and make the first twist between the two ends, thereby clinching the joint. Thereafter, the wire is further twisted by swinging the lever bar another ninety degrees from the position shown in Fig. 4, whereupon the clinched ends may be grasped with one hand and the tool released by swinging the locking arm I! upwardly and rearwardly to release the loop of one of the wires. Thereafter, the loose ends of the two joined fence members may be wrapped securely around the adjacent tensioned portions of the wires to complete the splice.

In this splicing operation, my improved structure has some very definite advantages over the structure of my fence tool disclosed in Patent No. 2,158,128. The hook I'lb being outturned and extended laterally from the arm ll, facilitates the engagement of the second wire since the loop of the second wire is disposed laterally outward of the point of connection of the first wire with hook [4a. In the second place, since the engaged portion of hook l'lb in its coupled position, is slightly below the axis of pivot [8a, arm I 7 will not inadvertently be swung in the twisting of the wire to form the clinch to release its engaged loop. From the described relationship, it will be seen that since the pull of a wire S (see Fig. 3) is imparted to the lock arm of the attachment element or hook I'Ib below the fulcrum of the lock arm, an over-dead-center relation is obtained whichprevents the lock arm from being inadvertently swung backwardly to release the wire. With my old device, the lock arm I! had to be held forwardly against the forward end of the bar L and if inadvertently released, one of the wires would be uncoupled and the free end might injure the hand of the operator, particularly if barbed wire was being spliced.

In addition to the several uses previously described the device may be utilized to pull staples from a post, by looping or otherwise securing the end of a wire to the hook Ma and then prying with the lever against the post, in a direction to cause the wire to transmit an outward pulling on the staples or staple.

In Figs. 8 to 10, I illustrate another embodiment of my invention which includes some additional features. In this form, the lever bar L is of generally similar construction to that of the form first described, comprising a narrow, U- shaped strap H, bent upon itself to form a relatively sharp post-engaging element B at the forward end of the tool and overlying opposite longitudinal edges of a combination handle and core member IE, but as shown, having teeth or corrugations I la formed on the upper side thereof.

The slide block 24 of thislast mentioned embodiment as shown, is in the form of a metal casting, having a V edge 24b for engagement with the shoulders Ha and carrying at its upper end, a rearwardly curved bifurcated, wire clinching claw 24a. Claw 24a has a converging entrance defined by longitudinal edges of the material whereby the fence wire having barbs or other enlargements thereon, may be firmly grasped and gripped. Theclaw 24:: at one or both sides thereof, carries short, spools 2410 upon which a smooth wire may be wound and hitched to secure the same to the claw.

The grab hooks 25 have their looped rear extremities detachably connected with eyes 24d extendinglaterally from the sides of the slide block 24 and in addition to the hooks at the forward end, are provided as shown, with converging clinching elements 25a which are adapted to The lock arm 21 of this embodiment is in the form of a metal casting having the outer extremity thereof, 21a, edged to Slightly penetrate and engage a fence post. The arm is pivoted by a bolt or rivet 28a to a heavy, upstanding lug 28, rigidly affixed to the upper section of the strap I I and adjacent the forward end of the lever bar. Integrally formed with the arm 21, is a laterally projecting outwardly andforwardly curved claw 21b, disposed it will be noted, slightly below the fulcrum axis of arm 21 and with its converging wire grasping portions disposed laterally outward of one of the sides of the lever bar. A short spool element 21c is integrally formed with the arm 21 disposed adjacent the fulcrum upon which a smooth wire may be wound several times and hitched if desired, to secure the same for splicing, pulling or other purposes.

The operations of the embodiment of Figs. 8 to 10 are similar to those of the embodiment first described, but in addition to all advantages of the first form, fence wires of different types may be secured either by clinching or winding of a smooth wire without the formation of loops at the ends of the wire, as is necessary in the first form.

With both forms of my invention, it will be seen that the weight and cost of the elongated lever bar are materially reduced without sacrificing any necessary strength. The combined core and handle member is completely reinforced throughout its medial and outward portion by the narrow, U-shaped strap which also forms the post-engaging point or element at its forward end and which, in addition, furnished the spaced shoulders or notices for adjustment of the slide block.

From the foregoing description, it will be seen that I have provided a simplified, but highly efficient, fence repair tool for performing a number of needed operations including the taking up of slack and stretching of fence wires without removing staples; the tightening of a wire in replacement or installation work; the splicing of broken wires, as well as the removal of staples.

It will of course, be understood that various changes may be made in the form, details, arrangements and proportions of the parts without departing from the scope of my invention.

What I claim is:

l. A tool for repairing wire fences comprising an elongated lever bar having a forward end adapted to be engaged against a fence post to facilitate l'ever action, a slide block embracing said bar and selectively adjustable in a multiplicity of positions on the medial portion of said bar, said slide block carrying a laterally projecting flanged spool for winding connection of a smooth fence wire thereon and a lock arm fulcrumed to the forward portion of said lever bar and having an outer end adapted to be swung into projecting engagement with the post in spaced relation to the engagement element of said bar, said lock arm also carrying a laterally projecting flanged spool for winding connection of a smooth fence wire therewith.

2. A tool for repairing wire fences comprising an elongated lever bar having a forward end adapted to be engaged against a fence post to facilitate lever action, a slide block embracing said bar and selectively adjustable in different positions throughout the medial portion of said bar, said slide block carrying an element for attachment to an end of a fencing wire and a lock arm fulcrumed to the forward portion of said lever bar above the same longitudinal side of said bar as said attachment element of the block is disposed; said lock arm having an outer handle end extending longitudinally of said bar and carrying a wire attachment element disposed outwardly and laterally of said handle end and adjacent the fulcrum of said lock arm and disposed eccentrically of and slightly below the fulcrum axis of said lock arm when said arm is swung forwardly to effect in reference to a wire connected with said lock arm and with said fulcrum axis, an off-set dead center relation when a rearward pull is imposed upon said attached wire.
