5 State of Montana, have invented a new and useful Improvement in a Combined Wire Stretcher, Splicer, and Tightener, of which the following is a specification;

This invention relates to an improvement in wire-stretchers and is adapted to hold the wire alongside of the post or other object to which the stretcher may be attached, so that the wire can be secured thereto, and is in the nature of an-improvement upon the construction disclosed in Letters Patent No. 785,511, granted to me on or about March 21, 1905.

The objects of this present invention are to provide means whereby the wire can be drawn to a much higher tension, means for bracket, means by which the stretcher can be vide a better wire-support and wire-clamp on the spar.

Reference is had to the accompanying drawin s, forming a part of this specification, in whic similar characters of, reference indicate corresponding parts in all figures. Figure 1 is a perspective view showing my invention as in operation. Fig. 2 is a sectional side view of the hitching-frame and 0 en pulley'mounted thereon and is a detail 0 this invention. Fi 3 is a sectional side view of end, taken at t e line 1 1, showing the Wire-support having a shoulder, which is .a detail of this invention. Fig. 4 is a sectional end view, and Fig. 5 a perspective view, of pulley bracket-frame, showing a pulley on its side, which is a detail of this invention. Fig. 6 is a transverse sectional view of bracketframe, taken at the line 2 2 on' Fig. 5, showing the dog employed and the spring to regu.-

the wire-clamp used. v The spar 2 may be made of wood or iron,

not necessarily round, having at one end a wire-clamp 10 and a rope-guide 2. Near the center is rope-guide-2 and at the other end a wire-support 4 and a longitudinal slot containing pivoted therein a grooved pulley 5. Attached to post 1 by a chain is hitchingframe 8, having a wire-clamp and chain attached to one end and the other end forming arope-eye 8 for the stretcher-rope 6 to pass through. On the top of frame 8 is pivoted a cent the frame.

releasing the dog from the rope in pulley groovedpulley 8, having an outward flange greater in circumference than the one adja- 8 is a bar projecting out over the flange of the pulley 8 This and the wide flange of the pulley keep the stretcher-rope in position. Bar 8 and pulley 8 are held in position by rivet 8, which has a smaller diameter through the frame than the pulley, thus allowing thepulley to rotate freely thereon.

' The wire-support 4 has a hook-like projeotion 4 at its lower end, which is adapted to engage the wire 3 when pressed down and to hold it against the spar by the force of coilspring 4 when released. 4 is a shoulder on wire-support which engages brace-frame 2 on spar 2 when the support is pushed forward, thus locking and making the support 4 stationary vertically. I

To release the wire from the hook, the support-bar must be pushed back from the top until the shoulder 4 is free from brace'2, then it can be pressed far enough through the slot to allow the wire to be disengaged from the hook. 2 -is a slot through brace-bar 2 and the spar having an elongated openin at the top gradually diminishing toward t e bottom,

thus allowing) the top of the wire-support a -of the dog released by a slight forward pull on the rope the spring will raise and hold the do from the rope.

%n the side of bracket-frame 7 is pivoted an open and grooved pulley 7 with an outward flange greater in circumference than the one adjacent the frame 7.

7 b is a bar projecting over the flange of the pulley, and it, with the wide flange, keeps the stretcher-rope in position. Rivet 7 passes throu h bar 7 b and open pulley 7 and with a'sma er diameter through bracket-frame 7 and pulley 7, thus allowing the pulleys their freedom in turning.

The wire-clamp 10 is riveted to the end of the spar and consists of a block 10 and a lever 10, fulcrumed at one side of the block on a projecting flange 10 and having a serrated head, which can bear against the block.

One end of stretcher-rope 6 is secured to bracket-frame 7 and passes from it back and over grooved pulley 5 in the spar, thence for ward along the spar through rope-eye 2 and rope-eye 8 in the hitching-frame, thence back to bracketframe 7 on its end and over grooved pulley contained therein and passing out under toe of the dog 7 thence returning to the hitching-frame 8 and around open pulley pivoted thereon, thence back to bracketframe 7 and around the open pulley 7 that is held to rotate on the side of the bracketframe, thence through rope-eye 2 on the side of the end of the spar.

When in operation, as draft force is applied to the end of the rope the spar, with the wire attached thereto, will move forward longitudinally and the front end of the spar can be drawn past the object to which the stretcher is hitched, so that the wire can be secured thereto. Thus it leaves no slack wire when the stretcher is removed. One of the principal improvements of this present invention is the open pulleys 7 and 8 which are not to be used until the wire has been partly drawn by the use of one loop in the rope, runningit from pulley within bracket-frame 7 out through rope-eye. Then enough rope can be redrawn through rope-eye to pass over the open pulleys, thus making another loop in the rope, which greatly increases the stretching power of the stretcher with the same draft force. It saves time and also prevents the inconvenience that would otherwise occur from the entanglement of the rope.

The bracket-frame to which one end of the rope is attached can be placed as far back as pulley 5, and as draft force is applied to the rope the bracket-frame moves forward, drawing the rope over the pulley 5 in the spar and forcing the spar forward. The bracket-frame can be drawn until it meets the hitchingframe 8. Then if the wire is not tight enough the operator can take hold of the bracketframe 7 and bring it back again to pulley 5, the stretcher-rope running over pulley 5 and slipping through rope-eye 7 d in the hitchingframe 8, thus giving another hitch. This op eration may be repeated, so that the wire can be drawn quite a distance without releasing it from the spar for another hold.

The wire-clamp 9 on hitching-frame 8 can be used to hitch the stretcher to a wire, as would be necessary in repairing a broken wire, and the ends be drawn past each other, so that they can be fastened together without leavin slack in the Wire afterthe stretcher is removed.

It can readily be seen that this device is simple in construction, easily used, and very effective in its work.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a wire-stretcher, a hitching-frame having at one'end a rope-eye, at the other end a wirecla1np, and pivoted thereon a grooved pulley having on its exposed side a flange greater in circumference than the in ner flange, a bar projecting out over said pulley, and a rope engaging the rope-eye and the pulley.

2. In a wire-stretcher, a bracket-frame with a pulley held to rotate on its side, said pulley having its exposed flange greater in circumference than the inner flange, and a rope engaging said pulley.

3. In a wire-stretcher, a bracket-frame, a grooved pulley held to rotate therein, a dog to engage the rope, a spring to regulate the said dog, shoulders on frame to hold spring, a grooved pulley held to rotate on the side of said frame, said pulley having on its exposed side a flange greater in circumference than the inner flange, a bar projecting over the pulley, and a rope engaging the pulleys.

4. In a wire-stretcher, a spar, a wire-sup port with a shoulder for looking it on the spar, a wire-clamp to secure the wire to the spar, a bracket-frame with a grooved pulley held to rotate therein and another grooved pulley held to rotate on the side thereof, a hitchingframe with a grooved pulley pivoted thereon and a rope-eye at one end of said hitchingframe, and a stretcher-rope, one end of which is secured to the said bracket-frame and the main portion making two loops, the first loop, by passing from the bracket-frame, to which one end is secured, over grooved pulley in the spar thence to and through the rope-eye in the said hitching-frame and back to the bracket-frame and over the pulley therein, the second loop, the rope passes from the bracket-frame to and around the pulley on the hitching-frame thence back a ain to the bracket-frame and around the pulley on the side thereof.

In testimony whereof I affix my sign aturc in the presence of two witnesses.
