WIRE-STRETCH ER.

SPECIFICATION forming. part of Letters Patent No. 504,127, dated August 29, 1893.

Application filed April 18, 1893- To all whom it may concern.-

Be it known that I, IRA F. EBERT, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Wire-Stretchers; andI do here by declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled .in the art to which it appertains to make and use the same. I

This invention relates to certain new and useful improvements in wire stretchers. With a device of this particular class as heretofore constructed, it hasbeen necessary in properly operating the same, to employ a special form of fence panel in combination therewith, which made an independent use of the same impossible and gave rise to numerone objections, owing to its 'inapplicability to other fences diifering slightly in construction. Again, the construction of such apeculiar form of panel usually required the aid of skilled and experienced workmen, which increased the cost and involved additional labor.

It is the object of this inventionlto obviate these defects and to that end, I provide an improved and novel straining device,'which-is adapted to be used independently or in combination with a simple and inexpensive tension bar by which fence or other wires may be strained singly and to any desired extent.

With these objects in view, the invention consists in various novel details of construc tion, combinations and arrangements of parts to be hereinafter more particularly set forth and claimed.

In describing the invention in detail,referonce is had to the accompanying drawings forming part of this specification, wherein like letters indicate corresponding parts in the several views, in which Figure 1* is a view in perspective of a wire fence, showing one form of my improved tension bar, applied thereto. Fig. 2- is a view in perspective on an enlarged scale, showing the straining device and bar in operative position on a wire. Fig. 2- is a view in elevation illustrating the preferred construction of the terminal panel of the fence. Fig. 3-

Serial No. 470,80L. (No model.)

is a detail view in sectional elevation of. the

lower portion of the straining device. Fig. 4 is a view in sectional elevation of a fence post showing the tension bar secured therein.

Fig. 5- is a view in horizontal section show-. :ing a modification of the same. Fig. 6 1s a detail View of a modified form of operating lever, and Fig. 7 is a view in perspective,

showing the application of the straining device, independent of the bar.

In the drawings: A represents a sec- .tion of a preferred form of wire fence, in

which -aaare the posts, and a-a the wires, loosely secured thereon by staples a or passed through openings a in I the usual manner. I of the section A may be provided with a Each end panel A double inclined brace a*-- which extends from near the center of one post to the ground line of the other, and a rigid or flexible tierod or stay a centrally connected to the brace -a and oppositely inclined and pro vided with a turn buckle or equivalent device a by which it may be strained or kept taut.

The fence wires aare each provided with a terminal hook b of any suitable construction. The preferred form however, is shown in Fig. 2-, wherein the bent up ends of the wires are passed through eyes -b of the hooks and turned back and wound [upon themselves forming loops a which permit a free movement of the hooks, independent of the wires. These hooks are adapted to engage apertures b of the inwardly projecting tension bars -B- which latter correspond in number to the fence wires and areadapted to be driven through openings -a in the end post of each section -A- and rigidly secured by the engaging points -b of the head b formed thereon, taking into the posts as shown. Various modifications of these bars B (see Fig. 5-) may be employed, the essential feature being the rigid connection with the 0st. p To properly take up or strain the wires, after the fence has been set up (as shown in Fig. 1-) I employ a straining device -O comprising an operating lever -cwhich to retain the device in proper position.

may be concentrically or eccentrically pivoted in'a foot piece c The lower end of this lever has secured thereto by bolts, a rounded metallic head --c having at the side thereof one or more upwardly curved teeth or projections c adapted for engaging the links of a chain -c* which latter passes between the walls -cof the foot piece and under the head c of lever and has attached to its outer extremity a claw-shaped hook -c''--. This foot piece c is provided with a rearwardly extending portion c having on the under side thereof a curved tooth or projection --c" which is adapted for taking into the apertures of the tension bars -B.

The operation of the invention as thus far described, is as follows: Assuming that the straining device is placed as shown in Fig. 2- with the foot piece thereof resting on one of the bars B and the downwardly extending tooth c engaging an aperture -b 1 the operating lever inclined toward the left as indicated in dotted lines, with the curved projection --c engaging a link of the chain and the claw-shaped hook locked behind the hook of a fence wire, the device will be in. operative position. If now, it is desired to adjust the tension of the wire, the operator pulls the lever toward the right, thereby winding on the chain, which tends to draw the wire taut, but should this movement fail to give the required tension, the pin c --which is attached to a short length of chain -c at the side of the foot piece, may be inserted into the openings c to engage a link: l of the chain c thus retaining the fence wire under tension and allowing the lever to be moved toward the left and a new hold 1 taken on the chain and the hook to be disen gaged and inserted into another aperture of the bar -B.

\Vhen using the device -O as a wire stretcher and independent of the bar -B it is preferably provided with a short length 1 of chain -D- having the terminal links thereof engaging the curved projecting teeth or lugs c --c of the head c and the 1 loop -cZ- passed over one of the posts a] of the panel A which serves as an an chor I To the outer end of the chain -c any well known form of wire clam-p -E may be.

ter of one post to the ground line of the opposite post, the apertured bars provided with integral engaging heads taking into and forming a rigid connection with one of said posts,

and the fence wires having terminal hooks adjustable in the apertures of said bars, as specified.

2. In a wirefence, the combination with a tension post, of the apertured bars having integral projections engaging said post and forming a rigid connection therewith, and the fence-wires provided with terminal hooks adjustable in the apertures of said bars, as specified.

3. In a wire fence the combination with a fixed bar havinga series of apertures formed therein and the fence wires provided with terminal hooks adjustable in said apertures,of a straining device removably mounted on the bar and comprising a foot-piece, a lever pivoted in the footpiece, and a wire engaging device connected with the lever, as specified.

4. A tension bar, comprising a rectangular and apertured body portion, provided w th an integral terminal head having engaging projections formed thereon, as specified.
