WIRE-FENCE TIGI-ITENER.

Specification of Letters Patent.

Patented Aug. .24, 1915.

To all whom it may concern:

Be it known that I, GRANT BULL, a citizen of the United States, residing at Wellman, in the county of WVashington and State of Iowa, have invented certain new and useful Improvements in WVire-Fence Tighteners, of which the following is a specification.

My said invention consists in certain improvements in the details of construction and arrangement of parts of wire tighteners, or stretchers, for use in the tightening of woven wire fabric, or wire strands, such as are used in the construction of wire fences of various types, whereby such an instrument is provided which may be used for tightening all of the wires used in the construction of a. fence simultaneously and without re-adjustment, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is a side elevation of a panel of a fence and one of my improved wire tighteners in the position it occupies when in use, Fig. 2 a top or plan view of the same, omitting the hand-wheel, and Fig. 3 a section looking downwardly from the dotted line 83 in Fig. 1.

In said drawings the portions marked A represent the fence posts, B the rotary winding post, C the clamp, and D the distance rod, or brace.

The fence is composed of the posts A and wires a, being, in the main, any ordinary or approved construction of wire fence. The diagonal brace A between the two posts A is such as used at the end, or corner, of the fence structure.

The winding post B is set in vertical position, being mounted at its lower end in a socket in a base block 10, of suitable size, adapted to be set into the ground and provided on one side with a wing 11 of sufficient length to hold said base block firmly from turning. Said post is mounted to turn in a socket in said base block and is provided at its lower end with a ratchet wheel 12, secured rigidly thereto, with which a pawl 13, pivoted on the top of said block, is adapted to engage. Near the top of said post it is provided with a horizontal plate, or yoke, 14 extending each way from the post for a considerable distance and having perforations in each of its corners. Said yoke is supported on a collar 6 secured to said post by a set screw, or pin, Z) the yoke thus serving as the upper bearing in which said post turns. Guy chains, or wires, 15 and 16 conne ct with the two holes in the rear side of sald yoke and are secured at their opposite ends to stakes 17 and 18 set into the ground a suitable distance back of the post and on each side thereof, to hold said post firmly against sidewise movement, and support it against the strain of the work.

The distance rod, or brace, D is formed forked at its rear end, a branch of the fork engaging in each of the perforations in the front corners of said yoke. The forward end of said brace is formed with a spike adapted, as shown, to engage with the adjacent face of the post A.

The clamp C consists of two vertical bars, of sufficient length, secured together by clamping bolts 0, the wires composing the fence panel being inserted between the two bars composing the clamp and securely clamped therein by means of said bolts. Chains 19 and 20 are each secured at one end to the clamp C and at the other end to the post B on which post they are adapted to be wound by the turning of said post through the medium of a hand-wheel b on its upper end.

In use the apparatus is assembled and set up as shown in Figs. 1 and 2 the base block 10 with the side wing 11 being imbedded in the ground to afford a firm anchorage and support for the lower end of the post B. The guy chains 15 and 16 are then adjusted and secured, the distance brace D put in place and the clamp C, connected by the chains 19 and 20 to post B is secured by the clamping bolts 0 to the free end of the wires composing the fence panel. By turning the post B, through the medium of the hand wheel I), and keeping the pawl 13 in engagement with the ratchet wheel 12, the wires may be tightened to the tension desired and then secured by the use of any approved securing devices.

By reason of the yoke 14 extending for a distance on each side of the upper end of the post, and its four corners being securely held by the rearwardly extended guys, and the forwardly extending forked brace rod, the upper end of said post is given a very rigid and secure support which is of decided advantage in the operation of the device.

By this means a very simple and convenient means for securing the necessary ten sion of the Wires is provided, and one that vention what I claim as new anddesire to secure by Letters Patent, is:

A wire fence tightener comprising a' vertical Winding post, means folholding said post comprising a base block formed with a socket and having means thereon to secure said post in rotary adjustment; a rectam gular plate or' yoke having a centrally ai' ranged aperture in which said post is ada e ed t6 turn sup orted near its upper end, an eye formed in each of the four corners of the yoke and at equal distance from the center, guys if tending from the e es in the rear corners of the yoke and connected some dis:

Copies of this pdt'iit may be oiitaiii'd in tance to the rear by suitable anchoring means, a distance rod formed with a spike on one end adapted to engage the adjacent side of thefence post and a forked rear end adapted to engage the eyes in the front corners of the yoke, a clamp for connecting with the Wires, and flexible connections between said clamp and the rotary post, substantially as set forth. 7

g In witness whereof, I, have hereunto set my hand and seal at VVeHman, Iowa this 21st day of July, A. D. nineteen hundred arid ten. v GRANT BULL. [L s.] Witnesses:
