STAPLE CLINCHER FOR STEEL FENCES Feb. 5, 1937 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

My invention relates to a special tool useful in fence construction.

An object of my invention is to provide such a tool which will efficiently and fence staple about the wire and 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 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 a tool of such character which is simple in construction and can be manufactured at a very reasonable cost.

, With these and other objects in view, my invention consists inthe construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, 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 staple about to be clinched,

Figure 2 is a plan view showing the tool Just before clinching, and taken in section along the lines`2-2 of Figurel,

Figure 3 shows the complete clinching operation, and

Figure 4 is a side view of Figure 2.

In wire fence construction, quite frequently a standard steel post of T shaped cross section is the iron post atmeans of a wire staple. The clinching of the staple requires tools such as pliers or the like and is quite a cumbersome method. I will show that in my invention that the clinching is accomplished quickly and eiciently Without resorting to any such auxiliary tools.

I have used the character IIJ to designate the standard type of steel post which is T shaped in cross section and having the central web I I. The post I0 also includes the projections I2 extending outwardly from the surface thereof, an'd between which is clinched the wire so that the same will not become displaced on account of these projections.

'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 quickly clamp a generally used, to which is clamped the wire by same thereover. To accomplish this result, I provide 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 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 extended into the integral portion 31 which in turn is bent at 38 into the enlarged portion 33 (see Figures 1 and 4). The pin 21 is attached solidly to the arm 28 which in turn is an integral extension of -the portion 30, which portion is an extension 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 further extension 33 terminates in the slightly arcuate 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 described, 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 with the arcuate members 32 against one edge a thereof and straddling the staple andwire. Then the arcuate portion 34 of the tool is placed against the other-edge as shown, and the tool is then in the position as 4shown in Figure 2 with the handles I9 and 20 at their widest divergence. Next the handles I8 and 2D are drawn together, and it will be seen that as these members are drawn together the member 23 will be pulled downwardly as well as the link 25, since the slot 26 is slidably engaged with the pin 21. At the same time, the upper portion 31 will be forced inwardly against the extended portion I8 of the staple during such movement, and the bentover member 39 will force the extension I 8 over the upper edge 35 of the web II, and at the end of the operation the bentover portion 38 will be pulled downwardly and against the web, thereby firmly clinching the extended member I8 into the bent over form as at 36.

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 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 adjustments 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 corresponding 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 construction, 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 construction ofegreat simplicity, and which can be manufactured at a resonable cost.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, andit is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

l. A staple clinching tool for steel fences comprising a rigid handle including means for engaging a post, a retractile handle pivoted thereto including a slidable link pivoted thereto, said link including a bent clinch an extended staple end to the post, said engaging means including pairs of opposed arcuate members for engaging the post edges and straddling the staple and wire fence member.

2. A staple clinching tool for steel fences of the type having a T shaped post, comprising a rigid handle including means for engaging two of the post edges, an ann attached to the handle including a pin, a link having an elongated slot slidably receiving said pin, a retractile handle pivoted to the rigid handle and said link, means lattached to said link adapted to rmly clinch a v staple end about the elongated web edge of said over extension adapted to- T shaped post when the handles are forced together.

3. A staple clinching tool for steel fences of the type having a T shaped post, comprising a rigid handle including means fo'r engaging two of the post edges, an arm attached to the handie including a pin, a link having an elongated slot slidably receiving said pin, a retractilehandle pivoted to the rigid handle and said link, means attached tov said link adapted to ilrmly clinch a staple end about the elongated web edge of said T shaped post when the handles are forced together, said means including a bent over clinching extension conforming to the bent over shape of the staple end when so clinched.
