RANDOLPH N. MARTZ, OF FREDERICK, MARYLAND.

WlRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 625,453, dated May 23, 1899.

Application filed July 26, 1898. Serial No. 686,944. (No model.)

To (all whom, it may concern:

Be it known that I, RANDOLPH N. MARTZ, a citizen of the United States, residing at Frederick, in the county of Frederick and State of Maryland, have invented a new and useful Tire-Stretcher, of which the following is a specification.

The invention relates to improvements in wire-stretchers.

The object of the present invention is to improve the construction of that class of wirestretchers known as mid-wire take-ups and to provide a simple, inexpensive, and efficient device of great strength and durability adapted to be readily applied to a fence-wire at any point between two fence-posts and capable of stretching a fence-wire to the desired tension and of being securely fastened in such position.

The invention consists in the construction and novel combination and arrangement, of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a wire-stretcher constructed in accordance with this invention and shown applied to a fence-wire. Fig. 2 is a similar view of the device detached.

Like numerals of reference designate corresponding parts in both figures of the drawings.

1 designates a wire-stretcher consisting of a bar or lever preferably flanged, as shown, to secure great strength and durability, and provided at one end with a short wire-engaging stud 2, and having adjacent to the same a longer pivot pin or stud 3, around which a fence-wire t is wrapped to tighten the same, as clearly illustrated in Fig. 1 of the accompanyin g drawings. The short wire-engaging stud is provided with an annular groove or depression to receive the fence-wire, which is looped around the short stud and which extends therefrom to the pivot pin or stud. The fence-wire is wrapped around the pivot pin or stud in the same direction, the direction of one side or portion of the wire being changed by the stud 2 to accomplish this result, and the said fence-wire may be wrapped around the outer portion of the pivot pin or stud without contacting with the short stud 2. By this construction the pivot pin or stud is subjected to all the strain, which is equalized, so that there is no unequal strain on the device, as would be the case were the fencewire wrapped around both studs. By constructing the wire-stretcher in this manner it is enabled to withstand a great strain without the slightest injury. The outer end of the pivot pin or stud 3 is provided with a head or flange to prevent the wire from slipping oif the device.

The handle portion of the bar or lever is slightly inwardly offset to bring its inner face in substantially the same plane as the face of the head of the short stud 2, and its outer end is provided with a fiat extension 5, forming a continuation of the central flange of the lever or bar and having oppositely-disposed flanges 6, arranged parallel with and spaced from the side flanges'of the bar or lever to form oppositely-disposed grooves adapted to receive the fence-wire, as clearly shown in Fig. 1. By providing a wire-receiving groove at each side of the handle end of the bar or lever 'the device may be stopped at the end of a half-revolution and does not have to be entirely rotated in order to bring it into a position for engaging the fence-wire. The horizontal plate or extension 5 is also provided with a perforation or eye adapted to receive a short piece of wire or tie for positively fastening the outer end of the bar or lever to the wire.

Under ordinary circumstances the bar or lever will give sufficient leverage for stretching a fence-wire to the desired tension; but when the device is applied to the heavier class of fence-wires it may be found necessary or desirable to employ a wrench or other tool for rotating the device, and in order to enable such a tool to be readily engaged with the device the latter is provided at a point directly opposite the inner end of the pivot pin or stud 3 with a squared projection or lug 8, which may be of any polygonal shape.

The invention has the following advantages: The device, which is simple and com= paratively inexpensive in construction, possesses great strength and durability and is adapted to be readily engaged with a fencewire at any point between the ends thereof. As the pin or stud upon which the wire is Wrapped is of greater length than the short stud 2, the'strain is equally divided and is borne solely by the solid pivot pin or stud. A wrench or similar tool may be readily engaged with the device at a point opposite the pivot pin or stud, and either face of the outer end of the bar or lever may be engaged with the fence-wire, so that the device need only be given a half-revolution, if desired. The bar or lever can also be positively secured at its outer end to a fence-wire, so that it cannot become accidentally-disengaged therefrom by cattle rubbing against the fence or like means.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed is 1. A wire-stretcher, comprising a bar or lever constructed of flanged metal and provided at one end with a fiat plate or extension forming a continuation of one of the flanges of the bar or lever and having oppositely-disposed flanges spaced from the latter to form opposite grooves to receive a fencewire, whereby the bar or lever may engage the same at either side of it, a pivot pin or stud extending from one side of the lever or bar, and a wire-engaging stud located adjacent to the pivot pin or stud, substantially as described.

'2. A wire-stretcher comprising a lever, a rigid pivot pin or stud located between the ends of the lever at one side thereof and adapted to have a fence-wire wound around it, a short eccentrically-arranged stud located at one end of the lever on the same side thereof as the pivot pin or stud and terminating short of the end of the same, and a double locking device mounted on the other end of the lever and adapted to engage a fence-wire from above or below the same, and comprising a perforated plate or extension, and flanges arranged on both faces of the plate or extension and forming wire-receiving grooves, substantially as described.

3. A device of the class described comprising a bar or lever provided at one end with a plate or extension having a perforation to receive a tie and provided with opposite grooves, a short wire-engaging stud extending from the other end of the bar or lever and rigid with the same, a rigid pivot pin or stud arranged adjacent to the short stud and pro jecting beyond the same, and a rigid wrenchreceiving lug located at the other side of the bar or lever at a point directly opposite the pivot pin or stud, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature in the presence of two witnesses.

RANDOLPH N. MARTZ.
