pnrrnn WALTER 1V. IDLE, F URBANA, OHIO.

WIRE-STRETUHER.

Application filed March 4t, 1916.

To all whom it may concern:

Be it known that I, l/VALTER W. IDLE, a citizen of the United States, residing at Urbana, in the county of Champaign and State of Ohio, have invented certain new and useful linproveiiients in Wire-Stretchers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved wire stretcher, and has for its primary ohject to provide a very simple and easily operated means for stretching a fence wire.

It is a more particular object of the invention to provide a device for the above purpose, including means for clamping the device upon a fence post, a slidably mount ed support, wire clamping means arranged upon said support, and manually operable means for shifting the support and thereby stretching the wire.

It is an additional object of the invention to provide operating means for the shiftable wire clamp, which includes an oscillatable lever, and means for moving said clamp in the same direction in the oscillating movement of the leverin either direction where by the wire may be quickly stretched.

It is still another object of the invention to provide a wire stretching means which is simple and durable in its construction, may be operated with a minimum of manual labor, and is capable of manufacture at relatively small cost.

ll ith the above and other objects in view, my invention consists in the novel features of construction, combination and "angement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a plan view of my improved wire stretcher showing the same as applied in operative position to a fence post;

Fig. 2 is a side elevation thereof;

Fig. 3 is a section taken on the line 33 of Fig. 2;

Fig. 4 is a section taken on the line 4l4:

of Fig. 2; and

Fig. 5 is a horizontal section showing the means for actuating the movable clamping jaw.

Referring in detail to the drawing, 5

jaw extending from the end of the rod 5 beyond said plates. Between the spaced plates 6, a movable clamping jaw 8 is mount ed upon the pivot pin 9. This jaw is provided with a shank portion extending between the plates, which has a series of cog teeth 10 formed upon its end. A lever ll. is also pivotally mounted. at one end, as at 12, between the plates (5 and is similarly formed with a series of cog teeth 13 meshing with the teeth 10 of the movable clamping jaw. The jaws 7 and 8 are adapted to be disposed upon opposite sides of a cylindrical steel corner post such as is now commonly used in the erection of wire fences, and when the lever 11 is forced inwardly toward the cylindrical body bar 5, the jaw 8 is also moved inwardly toward. the fixed jaw 7 and into clamping engagement upon the post. An elongated link, indicated at 14, is pivotally connected to the end of the lever 11 and is adapted to be swung over the end of the rod 5 so as to hold the lever against movement and retain the jaw 8 in its clamping position.

Upon the cylindrical rod 5, the sliding support 15 is mounted, said support including spaced parallel bars 16 disposed upon opposite sides of the rod 5 and in spaced relation thereto. One end of this support is formed with an angularly disposed lug 17, and adjacent to this lug the clamping cam 19 is pivoted, as indicated at 20. In the edge of this cam member, gripping teeth 20 are formed and are ad aptcd to bite into a fence wire arranged between the cam and the lug 17. In this manner, it will be apparent that the wire to be stretched may be very easily and quickly connected to the sliding support.

The arms 22 of a forked lever 2i straddle the cylindrical rod 5 and extend between the ars 16 of the support .15. These arms are mounted upon the pivot pins or screws centrally secured in the respective bars 16 of the support. Upon each side of the forked lever, a ring or annulus 52a is loosely engaged upon the rod 5, and to each of these rings links and respectively, are pivotally connected at one of their ends. The otl er ends of these links are pivotally held between the arn s of the forked lever upon relatively opposite sides of the rod a A coil s 'iring 2? is loz'isely engaged upon the rod, 5 between one of the rings 2t and the lever 21, and a similar spring 28 is disposer In thee-peration of the device, the same is first clamped upon the fence post in the manner above refe'rrel to, and the end of the wire is then securely clamped to the movable support 15'by means of the cam member 19. The operator now oscillates the lever In the movement of this lever in one direction, the link 26 will serve as the fulcrum, the ring to which said link is connected having frictional biting engagement upon the rod and remaining stationary thereon while upon the rod with the support. When the movement of the lever is reversed, the other link 26 becomes the fulcrum for the lever and the Support and the ring or annulus 2st which was formerly stationary is shifted upon the rod 5 in the same direction as formerly. Thus, the movement of the sliding support progressesoutwardly toward the end of the rod, such mo ement being limited by a stop pin or key indicated at 80, which is inserted through an openin in the end of the rod The finger piece 29 may now be pressed inwardly toward the operating lever and said lever, together with the support, again shifted inwardly upon the rod and posi tioned for the attachment of another fence wire, when the operation above described. may be'repeated.

From the above description, taken in connection with the accompanying drawing, the construction, manner-of operation and several advantages of my invention will be clearly and fully understood. The support provided with the clamping means for the wire may be turned upon the rod 5 and disposed in the most convenient position for the manipulation of the lever 21. The simple construction of the device renders the same highly durable in practical use and capable of easy and quick application or transportation from place to place.

\Vhile I have shown and described the preferred construction and arrangement of the several elements, it is, of course, to be understood that the same is susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is l. A wire stretcher including a supporting rod and means for clamping the rod to a. fence post, a slide member mounted, on they rod having parallel portions disposed on opposite sides of the rod and integrally connected at their ends, an operating lever pi\ otally mounted bet-ween the parallel portions of the slide member, rings engaged upon the rod on relatively opposite sides of the lever and adapted to frictionally engage said rod. links pivotally connected to the rings and to said lever upon relatively opposite sides of its pivot, and wire clamping means carried by the slide member.

2. A. wire stretcher including a supporting rod provided with means for clamping the same to a fence post, a slide member on said rod having parallel portions extending longitudinally on opposite sides of the rod, an operating lever pivotally mounted between the parallel portions of the slide member, rings engaged upon the rod on relatively 'op JOSite sides of the lever and at approximately equal distances therefrom, links connecting the rings to the lever 011 relatively opposite sides of its pivot, a spring (lislme'ecd between one of the rings and the lever and a second spring disposed between the other lever and one end of the slide member, said springs yieldingly holding the rings in trio tional engagement with the rod, and "ire clamping means on one end of said slide member.

In testimony whereof I hereunto allix my signature in the presence of two witnesses. lVALTEIl \V. IDLE. Witnesses Aivmznw Dr: Beaten, B. A. TAYLOR.
