G. sums STAPLE CLINCHER FOR STEEL FENCES Feb. 5, 1937 Z /9 /3 2,126,225Y 2,126,225 Patented Aug. 9, 1938 l UNITED STATES PATENT OFFICE , 2,126,225 ` s'rArLE cLmcnEa Fon STEEL FENcEs ` Glenn Simons, Larrabec, Iowa Application February 5, 1931, seria; »15,124,335 (Cl. 140-55) My invention relates to a special tool useful in fence construction. ` An object of my invention is to provide such a quickly clamp a „ tool which will efficiently and 5 fence staple about the wire and the iron post at tached thereto. A further object of my invention is to provide a tool `of such character which will clamp the staple firmly without the necessity of using pliers or 10 other such tools. , A further object of 'my invention is to provide means for clamping or clinching the staple in one operation. ‘ . A further object of my invention is to provide 15 a tool of such character which is simple in con struction and can be manufactured at a very reasonable cost. , ` With these and other objects in view, my in vention consists inthe construction, arrangement and combination of the various parts of my de vice, whereby the objects contemplated are at tained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which: Figure 1 is a fragmentary elevation showing a 25 staple about to be clinched, Figure 2 is a plan view showing the tool Just before clinching, and taken in section along the 20 lines`2-2 of Figurel, ‘ 30 Figure 3 shows the complete clinching opera same thereover. To accomplish this result, I pro vide the tool which will now be described, and which includes the handle I9 to which is pivoted the further retractile handle 20 which is pivoted at 2 I. The handle 20 is bent upwardly at 22 and CR terminates in the furthe!` horizontal extension 23 which is pivoted by means of the pin 24 to the link 25. The link 25 includes theopen lengthened slot 26 which receives the pin 21 beneath `which is positioned the Washer 28. 'I'he member 25 is ex 10 tended into the integral portion 31 which in turn is bent at 38 into the enlarged portion 33 (see Fig ures 1 and 4). The pin 21 is attached solidly to the arm 28 which in turn is an integral exten sion of -the portion 30, which portion is an exten 15 sion of the handle I9. ` The extension 30 extends into the portion 3l which terminates in the pair of arcuate portions 32 (see Figure 4), which portions are adapted to straddle the wire I5 as shown. Similarly, a fur 20 ther extension 33 terminates in the slightly arcu ate portion 34 which also straddle the wire in the same manner on the other side of the steel post. Now that the construction of my tool has been de 25 scribed, I will explain'- its operation. The staple itself is already formed in that form shown in Figure 2 with the lengthened portion I8 extending outwardly as shown. After the staple vis sprung into position as explained in Figures 1 and 2, the tool is placed against the steel' post Ill 30 with the arcuate members 32 against one edge tion, and ‘ ` ` a thereof and straddling the staple andwire. Then Figure 4 is a side view of Figure 2. In wire fence construction, quite frequently >a the arcuate »portion 34 of the tool is placed against standard steel post of T shaped cross section is the other-edge as shown, and the tool is then in 35 the position as 4shown in Figure 2 with the handles 35 generally used, to which is clamped the wire by - I9 and 20 at their widest divergence. Next the means of a wire staple. The clinching of the staple requires tools such as pliers or the like and handles I8 and 2D are drawn together, and it will seen that as these members are drawn together is quite a cumbersome method. I will show that be the member 23 will be pulled downwardly as well in my invention that the clinching is accom as the link 25, since the slot 26 is slidably engaged 40 plished quickly and eñiciently Without resorting with the pin 21. At the same time, the upper to any such auxiliary tools. I have used the character IIJ to designate the portion 31 will be forced inwardly against the standard type of steel post which is T shaped in extended portion I8 of the staple during such cross section and having the central web I I. The movement, and the bentover member 39 will force -_ the extension I 8 over the upper edge 35 of the 45 post I0 also includes the projections I2 extending web II, and at the end of the operation the bent outwardly from the surface thereof, an'd between which is clinched the wire so that the same will over portion 38 will be pulled downwardly and not become displaced on account of _these pro jections. 50 . >'I'he staple is indicated by the character I3, which staple is bent over at Il (see Figure 2) and thence passes under the wire I5 at I6, thence over the sameat I1 and terminates in the lengthened portion I8. The problem then is to bend the por 55 tion I8 `down against the web II and bend the against the web, thereby firmly clinching the ex tended member I8 into the bent over form as at 36. , ` 50 The linkages and pivots are so arranged tha after the member I8 is bent over the web, the arcuate portion 39 is then drawn down firmly. and in this way the entire staple I3 is then bent inwardly at Il and at 36 and the wire is then 55 2 2,120,225 m'mly clinched. ’Ihe tool is then released by spreading the handles apart, when it is then ready for the next operatic . ' e It will be understood, of course, that variations can be made in the tool, or the necessary adjust ments for accommodating diiferent standard sizes ofposts and staples. It will also be noted that the tool is positive in operation since the extended portion Il must necessarily bend the staple as described and -bring the same down in the corre sponding manner on account oi' swinging of the member 2i by virtue of the pivoted connections explained above. ' ' It will now be seen that I have provided a clinching tool for staples used in fence construc tion, which tool clinches the wire against a post in a minimum of time, which is convenient for ready use, which is positive in operation, and ' which emciently clamps the staple in the best manner without the necessity of using extra tools. It will be seen further that such a device would be particularly advantageous in the usual case where such operation should be accomplished quickly to accommodate a great many points of attachment. It will be seen further that I have provided the above mentioned characteristics in a con struction ofegreat simplicity, and which can be manufactured at a resonable cost. ' Some changes may be made in the construc tion and arrangement of the parts of my inven tion without departing from the real spirit and purpose of my invention, and‘it is my intention to cover by my claims any modified forms of struc ture or use of mechanical equivalents, which may be reasonably included within their scope.
