l"WIRE STRETCHER AND CUTTER.

SPECIFICATION forming paru of Leners Patent No. 721,442, dated February 24, 190s.

Application filed April 18, 1902.

g State of New Hampshire, have invented new and useful Improvements in a `Combined Wire Stretcher and Cutter, ofY which the fol.-

lowing is a specification.

This invention relates to a combined wire stretcher and cutter; and the object of the same is to provide asimple and effective form of tool which can be conveniently employed in stretching wire in the construction of fences or other purposes and also for severing the wire, as may-be desired.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figurel 1 is a perspective view of a tool or implement embodying the features of the invention. Fig. 2 is a side elevation broken away in part to show the mode of applying and operating the movable elements. v

Similar numerals of reference are employed to indicate corresponding parts in the views.

The numeral 1 designates a shank which is reduced at its rear extremity to form a tang 2, tted in a suitablehandle 3. The shank 1 has alongitudinally-extending slot 4forrned therein and vertically disposed to open out through the upper and lower edges of said shank. At the front terminal of the slot 4 the shank is formed with an upstanding shoulder 5, extending completely across the upper edge of said shank and formed with a rear concave face, and from the said shoulder the said shank continues into a conca-voconvex bracing-arm V6, adapted to be brought in contact with a postor other device during the wire-stretchingoperation, the concave j face of the said bracing-arm being formed with longitudinally extending corrugations or grooves 7 to provide reduced biting-surfaces to sink into a post or other device and prevent vertical slipping movement of the said arm during the wire-stretching operation. On one side of the shank 1, in rear of the shoulder 5, a cutter 8 is secured and has its upper extremity 9 projecting above the upper edge of the shank and given an inward Serial No. 103,602. (No model.)

ate obstruction of the ready insertion `or placement'of the wire against the said shoulder.

Within the forward part of the slot 4 a jaw 11 is pivotally mounted, thefulcrum or pivot device for the said jaw being located nearer its lower edge. The front end of the jaw has a forwardly-projecting lip 12 at its upper p0rtion, which is adapted to overlap the shoul- The front der 5, and immediately under said lip is a 1 convex bearing-surface 13, conformingin degree of curvature to the concave face of the shoulder 5, and between the bearing-surface 13 and the concave face of the shoulder 5 the wire is adapted to be clamped during the stretching operation, the said curvatures preventing thewire from slipping between the contiguous surfacesengaging therewith. The forward portion of the jaw 11 has its upper portion rising above. the upper edge of the shank 1 and of greater transverse extent than the lower portion of said jaw, andin the rear part of the jaw which stands above the shank is a wire-receiving recess or slot 14, with front and rear vertical 'straight walls, the cutting edge 10 of the cutter8 bearing closely against one side of the portion of the jaw which stands above the upper edge of the shank adjacent to the recess orslot 14. The rear extremity of the jaw 11 is formed with upper and lower contact projections 15 and 16, defined by the formationvof aslot 17, the upper projection having a curved bearing edge 18 and the lower projection a reduced rounded terminal 19. In rear ofthe jaw the head 20 of an operating-lever 21 is pivotally mounted in the slot 4:, the head 20 being of greater width than the lever and reduced in thickness to work in the said slot. has an extended convex edge 22 to engage the rounded terminal 19 of the projection 16. The

head 20 also has a shorter convex edge portion 23and a concave recess. 211 to coperate with the curved surface 18 of the'projection 15. The particular-shaped edge portions of 'the head 20 are always in contact with theo projections 15 and 16, and by moving the le- `This head 2O ICO ver downwardly the pressure on the projection 15 is relieved by bringing the recess 24 thereunder and applied to the projection 16 to throw the lip 12 upwardly and rearwardly from the shoulder 5, as clearly shown by Fig. 1. By drawing the lever 2l upwardly toward and against the shank 1 and handle 3 the shorter convex edge portion 23 of the head 2O is brought against the curved edge 13 of the projection 15, thereby lifting the rear extremity of the jaw 11 and throwing the `lip 12 downwardly on the shoulder 5.

In the operation of the device the jaw 11 is opened, as shown by Fig. 1, and the wire to be stretched is drawn in between the bearingsurface 13 and the shoulder 5. The lever 21 is then-drawn upwardly to close the jaw against and clamp the wire, and the bracinglever is then applied to a post or other device toward which it is desired to stretch the wire, the entire device then becoming a lever, as will be readily understood. After the wire has been suiiciently stretched it will be secured by any of the well-known methods, and if it is desired to sever the same it is inserted in the recess or slot 14 after the jaw has been iii-st opened. The lever 21 is then again drawn upwardly toward the shank and handie, and in View of the upwardly-moving action of the rear extremity of the jaw the wire to be severed is gradually raised and drawn toward the cutting edge l0 of the cutter 8 to thereby produce a shearing cut, which is facilitated by the inwardly-inclined arrangement of the upper extremity 9 of the said cutter.

The improved tool or implement is adapted for use in connection with barbed or plain wire and also will be found exceptionally convenient for the purpose for which it has been devised.

Having thus fully described the invention, what is claimed as new is- 1. In a tool of the class set forth, the combination of a shank having a handle at one extremity and a bracing-arm at the other extremity, the said shank having a slot therein, a jaw pivotally mounted in the said slot and having a forwardly-projecting clamping element to cooperate with a portion of the shank, and a lever for opening and closing the jaw.

2. In a tool of the class set forth, a shank having a handle at one end and a bracingarm at the other end, a shoulder being formed at the upper portion of the rear terminal of the bracing-arm, a jaw movably mounted in the shank and having a forwardly-projecting lip to overlap the shoulder, and a bearingsurface to coact with the latter, and a lever for opening and closing the said jaw.

In testimony whereof I aix my signature in presence of two Witnesses.
