WIRE-STRETCHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 597,059, dated. January 1 1, 1898. Application lerl May, 189?. Serial No. 635,152. (No model.)

To @ZZ whom it nung/concern- Be it known that I, FRANKLIN FOSTER, a citizen of the United States, residing at *Wood- Ward, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Tire Straining Devices, of which the followingisaspecification, reference being had therein to the accompanying drawings.

This invention relates to that class of Wirestretchers designed for use in building Wire fences; and the object is to furnish to the fence-builderasimple, light, and inexpensive preparatory to securing it to the posts.

To this end my invention consists of the peculiarconstruction, arrangement, and coinbination of a fulcrum-bar, an operating-lever, and straining and retaining Wireeclamps, all as more fully hereinafter described, and shown in the accompanying drawings, in Which-e Figure l is a perspective view of my improved tool, illustrating it as in operation. Fig. 2 is a plan of the device as in operation;

dev-ice, showing the parts in different position from that in Fig. l.

A is a fulcrum-bar provided With an arm D, extending .therefrom at right angles, or nearly so.

C are prongs secured to or formed on the bar A.

D is a lever pivotally secured upon the fulcrum-bar at E.

F is a standard on the free end of the arm B and carrying the retaining clamp-dog Gr, which is pivotally secured thereto, and His a lug for guiding the Wire beneath the clamp G.

The vlever D has pivotally secured at N near its fulcruin a bed-plate I, formed with a standard J, carrying the straining clampdog K, and with a lug for guiding the Wire beneath said dog.

In practice, the parts being constructed and arranged as described, they are intended to operate as follows: The fulcrurn-bar is abutted against the side of the post with the arm B extending in line with the Wire to be stretched, as shown in Fig. l. The Wire Mis then passed beneath the dog G and beneath the dog K, with the lever D extending in line with' the bar A. If the dog K is then tightcned down, it firmly clamps the Wire, and, drawing the lever in the direction as shown in Fig. 2, the Wire is strained. If the lever is now released, the dog G Will firmly clamp the Wire and retain itin position in order to obtain a new hold upon the Wire with the clamp II, for the purpose of straining it still further, if required. I preferably make the fulcrumbar A and arm B integrally of one piece of flat steel bar and maire the angle between the two preferably less than ninety degrees, so that the Wire will always be drawn up against the face of the post to which it is to be secured. Furthermore, I make slight bends in the bar at a and b to form an offset portion whereby the wire is lifted sufficiently above the arm B to permit of the convenient driv ing of a staple to fasten the Wire. I also provide the arm D With a slight bend at c for the purpose of bringing the fulcrum E, pivot N, bed-plate I, and free end of the arm B all in horizontal plane with each other for the purpose of getting a straight pull on the Wire.

The object of pivoting the bed-plate I upon the lever D is to allow it to adjust itself in line with the Wire during the ope-ration of the lever, and by this means it will be seen that the stretching of the Wire is accomplished Without producing any kinks or bends in it,

and not a particle of the fence-Wire is Wasted.

What I claim as my invention isl.v In a Wire-stretcher, the combination of a fulcrum-bar, an arm extending forwardly at an angle to the fulcrum-bar, an automatic clamp at or near the forward end of the said arm, an operating-lever fulcrunied to the fulcrum-bar, and an automatic clamp pivotally secured to the operating-lever and provided With means for retaining it in proper relation to the Wire, substantially as described.

2. The combination of the fulcrum-bar provided With an arm extending therefrom at substantially a right angle, a Wire guide formed at the free end thereof, a dog pivotA ally mounted above the same and formingin connection therewith an automatic retainingclamp, an operatinglever fulcru med upon the fulcrumhar, a swinging Wire-guide pivotally mounted upon the operating-lever and a dog pivotally mounted upon said wire-guide and IOO forming in connection therewith a strainingclamp.

3. In aWire-stretolier, the Combination of the pronged fuleruin-bar A, provided with the arm B and bends a and l), the standard F thereon carrying the retaining-dog G, the guide-lugH, the operating-lever D, the swinging bed-plate I provided with the lug L and standard J, and the straining-dog K pivotally secured thereto. v

4. In a Wire-stretcher, the combination of an angular fulerum-bar provided with an offset port-ion, a clamp on the bar at one side of Said offset portion, an operating-lever fuleruined to the fnleruin-bar on the opposite side of the oilset portion, and a clamp carried by said lever, substantially as described.

5. In a Wire-stretcher, the combination of a fulerum-ba-r, an arm extending forwardly at an angle thereto, a standard at or near the Operating-lever fulerulned to said bar, and an automatic elarnp` Carried by said operating lever and adapted to clamp the Wire in any position of the lever.

In testimony whereof I aix my signature in presence of t-Wo witnesses.
