JAMES ALEXANDER MASON, OF SAVOY, TEXAS.

WlRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 366,853, dated July 19, 1887.

Application filed May 25, 1587.

T0 aZZ whom, it may concern.-

Be it known that I, JAMES ALEXANDER DIA- soN, a citizen of the United States, residing at Savoy, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in \Vire-Strctchers; 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 it consists in the novel construction and combination of the parts, hereinafter fully de scribed and claimed;

In the drawings, Figure 1 is a plan view fro m above, she wing the wire-stretcher secured to a fence-post. Fig. 2 is a side view of the wirestretcher.

A is a flat bar, having arms a and a secured to it by bolts a. Spikes a" project from the ends of the arms, and the upper arm, a, is made to project farther from the bar in each direction than the arm a, so that the spikes may take hold of the post better. The front end of bar A has a curved portion, a, in front of the spikes a.

B is a quadrant-plate projecting from the plate A, and having notches b in its edge. A boss, a is formed at the rear end of bar A and provided with the ovprhanging projection a.

O is an eccentric pivoted to the boss a upon pin 0, and provided with the handle 0 for working it. The projection a is made long enough so that the eccentric can be turned round and caused to grip a wire against it in the reverse direction from that shown in the drawings. Side flanges, 0 are provided on the eccentric to prevent the wire from slipping out. These flanges are not continued all round, but. a space is left between them, so that the wire can be inserted between the eccentric and the projection when the eccentric is not in a position to grip the wire.

D is a lever provided with the handled, and pivotally connected to the bar A by the pin d.

E is a detent pivoted to the lever D on the pin 0, for engaging with the notches in the quadrant. A spring, 0, is provided for press ing the detentinto the notches, and c is ahandle for raising the detent clear of the notches.

Serial No. 239,813.

(No model.)

F is a plate on the other side of the quadrant from the lever D, for supporting the detent and stiffening the said lever.

G is a plate pivoted at one end to the lever D upon the pin g, and provided with the overhanging projection y.

H is an eccentric pivoted to the plate G upon the pin h, and provided with the side flange, h, and handle it.

\Vhen used to stretch a fence-wire, the machine is secured to apost, as shown in Fig. 1. The lever D is turned forward and the wire seized by the eccentric H. The lever is then brought round and the end of the wire seized by the eccentric O, and the lever again moved forward to get a new grip farther along the wire. To unite the broken ends of a fencewire, one end is first pulled through the eccentric G and gripped, the said eccentric being turned round to a reverse position from that shown. The other wire is then seized by the eccentric and brought round by means of the lever D, so that the two ends of the wires can be united.

\Vhat I claim is- 1. In a wire-stretcher, the combination ofa bar provided with a toothed quadrant and with a boss having an overhanging projection at its rear end, an eccentric pivoted on the face of the said boss for holding the wire against the projection, a hand-lever pivoted to the bar and provided with a spring-detent engaging with a toothed quadrant, a plate pivoted at one end to the hand-lever and provided with an overhanging projection, and a second eccentric pivoted upon the face of the plate for gripping the wire against the projection, sub stantially as setforth.

2. In a wire stretcher, the combination of a bar provided with a boss at its rear end having an overhanging projection, an eccentric pivoted upon the face of the boss, so that it will automatically hold the end of a wire against the projection, a hand-lever pivoted to the bar, a retaining-catch secu ring the lever to the said bar, a plate pivoted at one end to the handlever'and provided with an overhanging proj ection, and asecond eccentric pivoted upon the face of the plate for gripping the wire against the projection, substantially as set forth.

3. In a wire-stretcher, the combination of a bar provided with atoothed quadrantand with a boss at its rear end having an overhanging projection, spiked arms of unequal length secured upon opposite sides of the bar for at- 5 taching it to a fence-post, an eccentric pivoted on the face of the said boss for holding the wire against the projection, a hand-lever pivoted to the bar and provided with a springdetent engaging with the toothed quadrant, a

10 plate pivoted at one end to the hand-lever and provided with an overhanging projection, and a second eccentric pivoted upon the face of the plate for gripping the Wire against the projec= tion, substantially as set forth.

In testimony whereof I aflix my signature in 1 5 presence of two witnesses.
