THOMAS M. SNELLING, OF LA JAR/A, COLORADO.

WIRE-STRETGHER.

To all whom it may concern:

Be it known that I, THOMAS M. SNELLING, a citizen of the United States, residing at La Jara, in the county of Gonejos and State of Colorado, have invented certain new and useful Improvements in Wire-Stretchers; and I do hereby 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.

This invention relates to wire stretchers, and one of the principal objects of the same is to provide an efficient tool of simple construction for stretching the wires between two fence posts, after the wires have been severed, so the ends may be connected or spliced together to take up the slack and to tighten the wires.

Another object of the invention is to provide means for clamping the wire at two points after the line wire has been severed and for drawing the severed ends together a sufficient distance so that they can be united by pliers or other tools fortaking up the slack in the line wires, such stretcher being so constructed that a free space is given for the splicing operation.

These and other objects may by means of the construction illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of a wire stretcher secured to the upper line wire of a fence, said line wire being severed and the wire stretcher being in position to pull the wire from opposite directions at opposite sides of the parted ends, Fig. 2 is a sectional view on a larger scale of the rack and pawl mechanism in one of its positions, Fig. 3 is a side elevation of the same in another position, Fig. 4 is a detail sectional view and partial elevation of one of the wire; clamps, Fig. 5 is a side elevation of the same, and Fig. 6 is a sectional view taken on the line 66 of Fig. 3, looking in the direction indicated by the arrow.

Referring to the drawings, the numeral 1 designates one member of the stretcher and 2 is the other member thereof. The member 1 has an angular arm 3 and-the member 2 has a similar arm 4. These arms each have a terminal lug 56.

The wire clamps are substantially identical in construction, and hence the description of one will serve for both. Each clamp consists of a lever 7 having an eccentric Specification of Letters Patent.

. the line wire, and said lever is pivoted upon a bolt 9 extending eccentrically through the head 8 and inserted into the arm 4, as shown in Fig. 4. The head 4 is disposed immediately under the lug 6, and the latter serves as the stationary jaw of the clamp. Formed integral with the lever 7 is a guard'lO, and when the lever 7 is swung in one direction, the wire a may beinserted between the lug 6 and the head 8 of the clamp, and when the lever isswung in the opposite direction, the wire is clamped between the lug 6 and the head i The member-1 of the stretcher is provided with spacedguides 11-12 connected thereto by rivets or bolts 13, and the member 2 is mounted to slide in said guides. The member 2 on its lower edge is provided with a series of ratchet teeth 14. A lever comprismg spaced members 15 is pivotally connected at 16 to depending bearing members 17 rigidly connected to the member 1 by rivets or bolts 18. Pivoted at 19 between the the upper edge of'the member 1, while the opposite end bears against a screw threaded plug 25, said plug being adjustable in the backstop to regulate the tension of the spring 24. The lower end of the backstop 22 is inclined, as shown at 26, to engage the ratchet teeth 14, and the outer portion of the I part 26 bears upon the curved surface 21 of the pawl 20 to hold the nose 27 of the pawl into engagement with the teeth 14 during one movement of the lever 15. The pawl 20 is engaged frictionally with the member 15, so that when the lever is moved. towardthe left, as shown in Fig. 2, the nose 27 of'the pawl will disconnect from the teeth 14 until the curved member 21 comes in contact with the part 26 of the backstop, at which time the nose 27 will be forced upwardly into engagement with one of the teeth 14.

The operation of the stretcher may be briefly described as follows: The clamps are engaged with the wire a at some distance apart, and the wire a is severed between the clamps. By moving the lever 15 toward the right, the member 2 is moved in the same direction through the guides 11 and 12, and the opposite ends of the wire a are brought together and by means of a suitable plier or tool the severed ends are twisted and the slack is taken up. It is to be noted that the members 1 and 2 are disposed at some distance from the wire a, and hence there is plenty of room to operate the pliers for twisting the ends of the wire together.

Various changes may be made in the details of construction without departing from the spirit and scope as defined in the appended claims.

What is claimed is 1. A wire stretcher comprising a relative stationary member, a relative movable member having ratchet teeth and being slidably mounted on the relative stationary member, a guide carried by the relative stationary member and engaging the other member, a back stop slidably mounted on the relative stationary member and its lower end cooperating with the teeth of the movable member, and spring means holding the back stop in an adjusted position upon the members.

2. A wire stretcher comprising a relative stationary member, a relative movable member provided with ratchet teeth and slidably mountedon the relative stationary member, guidescarried by one of the members and engaging the other member, a back stop secured to the stationary member and having its lower end curved to conform to the configuration of the teeth of the movable member, a spiral spring seated in the upper end of said back stop, one end of said spiral spring resting on the upper edge of said stationary member, a screw plug on the end of said back stop for engaging the free end of said spiral spring for adjusting the tenion of said back stop on the stationary member.

3, A wire stretcher comprising a relative stationary member, a relative movable member provided with ratchet teeth and slidably mounted on the relative stationary member,

In testimony whereof I aflix my signature in presence of two witnesses.
