spacedportionsldand the'c onnection 14: are

integrally formed of sheet metal, as shown in Figures 1, 5, and 6. The gap 15 provided between the portions 13 form a guide for the wire, as shown in Figures 2 and The conneetio'nf 14 is off-set from the lower edges 16 of the legs 2 and 3, as best shown inFigthrough the gap 15 adjacent to the conneetionl l, is out of alinement with the medial plane of the frame legsQ and hthereby causing the tool to normally retain i the position ure 3, so that the wirestrand l7, 'passlng i shown in Figure 3, while the shaft 4 is being rotated to tighten the wire.

In Figures 2 and 3, the tool is positioned as when used for splicing a new piece of wire into a broken wire. As here shown the broken wire 18 has loops 19 and 21 provided at the broken ends thereof, the latter being engaged with notches 22 provided in the edges 23 of the frame, as shown in Figures 1 and 3. The bottoms of these notches are preferably inclined as shown in Figure 6 to cause the wire loop engaged therewith to move outwardly away from the medial plane of the frame. The wire 17, use'd'for splicing together the ends of the wire 18, may have one end wound upon the shaft 1, as shown in Figure 2. One end of this wire is then secured to the loop 19 of the broken wire 18, as shown at 25, in Figures 2 and 3, and passes through the guide provided between the frame portions 13, connection 14: and the portion 26 of the wire loop 21, as shown in Figure The hand grip 12 is then operated to rotate the shaft 4:, whereupon the wire 17 will be wound upon the shaft, resulting in the wire 18 being pulled taut because of the wire 17 being connected with the loop 19 and the frame of the tool being secured to the loop 21 of the broken wire. When the wire 18 has been pulled suiiiciently taut, the tool frame is manually moved from the full to the dotted line position shown in Figure 3, after which it may be rotated about that portion of the splicing wire 17, connecting together the loops 19 and 21 of the broken wire, thereby splicing a piece of new wire into the broken wire while holding the latter taut.

In Figure 3, it will be noted that the notches 22 at the end of the tool frame are located substantially in alinement with the edges 16 of the legs 2 and 3, so that the splicing wire 17 passes beneath the portion 26 of the loop 21 adjacent to the connection 1 1, which is sufficiently out of alinementwith the medial plane of the tool frame to cause the tool to be normally retained in the position shown in Figure 3 without any danger of the right hand end thereof, when viewed as shown in Figure 3, accidentally swinging upwardly to the dotted line position shown in this figure. Thus, it will be seen that the tool will retain its normal operating position while the shaft 4 is being rotated to pull the wire taut, the ratchet 9 and dog 11 functioning to hold the shaft in adjusted positions while s licing the new wire 17 between the broken ends of the wire 18.

Means are also provided upon this novel wire stretching and splicing tool for anchoring the tool frame to a fence post,when it is desired to tighten a wire and secure one end thereof to the post by coiling it thereabout.

Figure 4: illustrates the operation of the tool when used to thus secure a wire to a fence post. To prevent the tool from slipping upon thepost, it is provided with prongs 27, formed at the upper corners of the edges 23 of the frame. These prongs are adapted to dig into the post as shown in Figure 4, when the tool is swung in the direction indicated by the arrow in this figure. To tighten the wire between posts, the end of the wire may be pulled around a post in the following manner: the prongs 27 of the tool are engaged with the periphery of the post as shown in Figure 1, and the tool frame to which the end of the wire is secured by means of the ratchet-locked shaft i, is oscillated or moved in the direction indicated by the arrow, using the prongs as apivot point, until it reaches the dotted line position indicated by the letter A. The operator then tilts the tool frame backwardly and at the same time exerts an' outward pull thereon until the prongs 27 and tool frame are moved out of engagement with the post. \Vhen the prongs are thus disengaged from the post, the operator, while pulling outwardly on the frame, will shove theprongend thereof forwardly and at the same time tilt the outer end of the frame backwardly and allow the edges 23 to engage the periphery of the post. The tool frame is then tilted forwardly, thereby causing the prongs 27 to again engage the post. Because of the frictional engagement of the wire with the periphery of the post, the operator can easily hold the wire against slippage on the post while shifting the tool frame as above described. As the tool frame is moved forwardly to the dotted line position indicated by the letter B, the wire will move relative to the post and become tightened between posts. This operation is repeated until the wire has been sufficiently tightened.

Figure 5 illustrates the tool as used when forming a loop upon one end of a wire.

When thus forming a loop, the wire is bent upon itself and the end of the wire and also the wire proper are then held by a pair of pliers or some similar tool, after which the tool frame is rotated to twist the two strands of wire, as clearly shown in Figure 5, thereby providing a loop at the end of the wire, as shown.

The tool is very simple and inexpensive in construction and may be manufactured at a minimum cost. The frame is constructed of sheet metal by suitable blanking and forming dies. Figure 6 shows the frame when blanked from a piece of sheet metal, the apertures 5 and 6, notches 22 and prongs 27 being formed in one operation, after which the metal is bent by suitable forming dies to the form shown in Figure 1. The integral structure of the frame therefore is an important feature of the invention because it greatly simplifies the construction of thetool and also results in the production of a tool which may be manufactured. at a very small cost, "no machine work being required in the manufacture of the tool.

a In Figures 2 and 3 of the drawings, the tool is shown as 'usedfor tightening and splicing a smooth wire. Obviously, it may be used for tightening and splicing other kinds of wire as,'for example, the barbed wire shown in Figure 4; The guide rovided between theparallel portions 2 is sufficiently wide to permit the barbs to pass therethrough, 'as shown in Figure 4. g
