WIRE-FENCE CLALVEP.

Application filed December 2-1, 1922. Serial No. 608,296.

Tore- Z whom it iimg concern:

Be it known that l, WiLLIAiiI G ROBIN- SON, a citizen of the United States,residing at Batavia, in the county of Jei'l'erson and Stateof Iowa, have invented certain new and useful Improvements in Wire-Fence Clamps, of which the following is a specification.

My invention relates to clamping devices especially adapted for use upon wire fence fabrics, when stretching the same, and one object of the invention is to provide such a clamp, which is of simple and durable constructlon, and which may be easily. and quickly applied to the fence fabric and as easily detached therefrom.

One embodiment of the invention is illus trated in the accompanying drawing, wherein Figure 1 shows a side elevation of the device in operation Figure 2. a top plan view of Figural, and

Figure 3, a fragmentary end View of Fig ure 1.

In the drawing, reference numeral 10 represents a wire net or" any kind suitable for "fence construction, and clamps, indicated, in general, by numeral 11, ripping the wire in order to stretch the same preparatory to fastening it to a fence post.

Each clamp consists of two

jaw members

12 and 13 of L-shape, the long arm 01" which terminates with an ear 14, to which a link 15 is attached to swivel around a pin or rivet 16.

The short arms 17 and 18 of the

jaw members

12 and 13 are turned inwardly approximately 90 degrees from the long arms there or". One of these short arms terminates with a hook 19 and the other short arm 18 terminates with a corresponding eyelet 20 adapted to interengage. The fiat, opposing surfaces 21 of the short arms 17 and 18 are spaced apart, as best seen in Figure 2, and in this space is inserted the long legs 22 of the angle irons 23, while the other legs 24 thereof reach across to the long arms of the

jaws

12 and 13. The angle irons 28 are of sufficient length to accommodate two each of these

jaws

12 or 13, as seen in Figure 1, and flanges or wings 25, running up and down. from the jaws, furnish securing meansfor the angle irons 23, which are held in position by rivets 26 or the like. 7

In this manner two pairs of j aw are furnished, one situated above the other on one a cable or chain 28 for pair of angle irons best seen in Figure 1 of the drawing. The links 15 are connected by means of a hook 27, to which is att hed ulling the jaws in the direction of: arrow In, in order to stretch the wire fabric.

The operation of the device is as follows:

The two pairs of jaws are separated, together with their angle irons 23, that is to say, the

connection

19 and 20 is unhooked and the wire net is then entered between the angle irons 23, and the hooks and

eyes

19 and 20 coupled together a short distance back of the end of the wire net, as seen in Figures 1 and 2 of the drawings. The long arms of the

jaws

12 and 13 are then drawn together until the legs 22 of the angle irons 23 close up around the wire net, so as to hold it firmly and in flat position, whereupon the book 27 is introduced into the links 15. By now exerting a pull upon the cable or chain 28, the wire net will be stretched in the direction oi arrow X, it being assumed that the opposite end or" the wire net is secured on fence post.

After the end of the wire net, where the clamps are attached, has been secured to the fence post at this end, the pull on the cable or chain 28 is slackenec, whereupon the clamps will release their hold upon the wire net and may then be readily removed therefrom by swinging the long arms of the

jaws

12 and 13 apart sufliciently to permit the disengagement of the hooks and

eyelets

19 and 20, whereupon the operation is repeated at the next fence post.

By making the

jaws

12 and 13 in L-shape with the short arms 17 and 1S oiTset in inward direction, a very simple construction has been provided and it will be evident that no other operation is needed beyond. the drilling of the holes for the, rivets 26 in the angle irons 23 "for securing the latter to the jaws. Another advantage of constructing the clamps in this manner resides in the fact that the angle irons do not need to be weakened in any manner to carry the

jaws

12 and 13.

Another advantage of the construction of this device is that, no machining whatsoever is required as the parts may be forged or cast in this shape, and that, the necessary apertures for the rivets and pins may be cored.

The advantage or using angle irons for gripping the wire net will readily be understood as the Wires, in this manner, are held in flat position between the angle irons and, accordingly, no crimping or bending of the Wires will occur as is the case of other devices of similar character.

Having thus described the invention, What is claimed as new is:

l. A fence clamp comprising a pair of jaws detachably interlocked at one end thereof, fiat-faced wings integral with the jaws, angle bars secured on said Wings, and means for drawing the free ends of the jaws together.

2. A fence clamp comprising a pair of angle bars constituting gripplng members,

mating jaw members having each a long and a short arm, said short arms having interlocking elements, Wings lIItQ/gIELl WIt-h said jaw members positioned at the juncture of said longiand sh'o'rtarms said Wings being so rigidly united With the respective angle WILLIAM G. ROBINSON. LQ s;]
