UNITED STATES PATENT OEEICE.

HERMAN J. ROHR, OF ALEXIS, ILLINOIS.

WIRE-STRETCHER.

SPECIFICATION forming part of Letters Application filed January 2l., 1892.

T0 all whom it may concern:

Beit known that I, HERMAN J ROHR, a citizen of the United States, residing at Alexis, in the county of Warren and State of Illinois, have invented a new and useful fire-Stretcher, of which the following is a specification.

This invention relates to fences, and more especially to the wire-stretchers adapted to be used on fences to stretch, tighten, or splice the wires thereof; and the object of the same is to provide a device which when secured to a fence-post will stretch the wire on either side thereof and will,if desired,draw the wire across said post, so that it can be stapled thereto.

To this end the invention consists in a stretcher substantially as hereinafter more fully described and claimed, and as illustrated on the accompanying sheet of drawings, wherein- Figure l is a front elevation of this device in use on a post as for drawing wires in one direction toward or across the post. Fig. 2 is a plan View of the device applied to a post and also showing the use of the machine for splicing wire, in which case the device may be used independently of the post. Fig. 3 is a perspective detail of a portion of the body, omitting the reel, and of the brace and chaintightener. Fig. 4 is a perspective detail of the post-claw.

In the said drawings, the letter B designates the body; P, the post-brace; K, the post-claw; T, the chain-tightener; R, the reel or windlass, and C, C', and C the wireclamps, these parts being each preferably of the following speciiic construction:

The body B consists of a cylindrical metal bar 1, having a notch 2 in oney end and having its other end turned up into a tapered journal 3, whereon is mounted the reel R. On the body between its ends is rigidly sesecured a collar 4, adjacent which is formed a number of holes or depressions 5.

6 is an enlargement on the body, which carries the wire-clamp C, used for splicing purposes, and one of the pawls of the reel.

The post-brace P consists of a block l0, encircling and loosely fitting the body, through which block passes a set screw or pin l1, which seats in one of the holes 5, whereby the block can be adjustably set on the body.

Patent No. 475,892, dated May 31, 1892.

Serial No. 418,739. (No model.)

Through this block also passes a stout bolt l2, which takes into the head of an approximately U-shaped yoke 13, preferably having feet 14 at its ends, and one side of this yoke is serrated, as at l5, while the other side is notched, as at 16, as shown.

17 is a chain forked at one end, as at 18, and embracing the sides of the yoke, its terminal links fitting removably in the notches 16, and the other extremity of this chain is adapted to be passed into and held by the notch 2 in the body 1.

Between the ends of the chain 17 a postclamp K is mounted thereon. This clamp comprises a straight and preferably flat body 20, of sheet metal, with ears 2l at its ends, each ear being provided with a hole 22 of a size to receive and slide over the chain, and at each side of each ear is an int-urned prong 23, adapted to be embedded in the back of the post 25, as seen in Fig. 4.

The chain-tighteuer T consists of a block 30, encircling and loosely fitting on the body l and having a finger 3l, provided with the teats or prongs 3l, for a purpose to appear farther on. Through the body turns a screw 32, having a crank-handle 33 at its front end. 34 is a sleeve fitting on the rear end of this screw and held in place by a split pin 35, and 36 is a hook rigidly secured to and projecting rearwardly from the sleeve 34.

The reel R comprises a cylindrical body 40, having a tapering bore, which is journaled on the journal 3 of the body B, whereon it is held by a nut4l, and at the ends of the cylindrical body are heads 42 and 43, the latter having ratchet-teeth 44 in its periphery.

45 is a spring-'actuated retaining-pawl pivotally mounted on a bolt 46 through the enlargement 6 and engaging the ratchet-teeth 44 to prevent a retrograde movement of the spool.

47 is ayoke whose endsare pivotally mounted on the journal 3 outside the heads of the spool. 48 is a handle projecting radially from this yoke, and 49 is a spring-actuated pawl carried by the yoke and engaging the ratchetteeth 44, by which construction when the handle is reciprocated the spool is turned, as will be clear.

Leading from an eye 50 on the cylindrical body 40 of the spool is a small chain or stout cord or rope 51, which extends to the clamp C. The latter consists of a body 52, to which is pivoted at 53 a lever 54, having an eccentric face 55, adapted to contact with a lip 56,'

the head of the lever preferably, also, having a flange 57, moving over the edge of the lip, to prevent the fence-wire 100 from slipping off the same. The other clamp C is of the same construction and bears the same reference-numerals, except that they are primed, and 5l is a small chain or rope leading from this clamp to a bolt 50', which passes across the notch 2 in the body B. Theclamp C consists of a similar lever 54, journaled on the lower end of the bolt 46 and having an eccentric face 55, aotingin conjunction with a lip 56, carried by the body B, and also an encircling flange 57, corresponding to the other clamp-flanges 57 and 57, respectively.

With the above construction of parts the operation of my improved device is as follows: The body B is placed alongside a post, as seen in the drawings, with the serrations l5 of the post-brace P against one edge of the post, and the chain 17 is passed around behind the post and engaged in the notch 2. The screw 32 of the tightener T is then turned in. The sleeve 34 is locked on its inner end by the split pin. The hook 36 is engaged with one of the links of the chain, and the screw is reversed or unscrewed to twist the chain to Stich an extent that it shall be drawn very tight between the corner of the post and the slot 2, whereby the body B will be tightly clamped to the post. If the wire is to be drawn in both directions, of course the clamp C is employed, though the body B is not connected with the post, as just described; but if the wire is to be drawn in one direction toward or across the post, as shown in Fig. 1, the clamp C is run past the post from the reel R and engaged with the wire 100, after which the reel is turned in the manner described. To draw the wire from the other side toward the post, the device is clamped to the post on the other side thereof, or if it has just been used, as shown in Fig. l, this same clamp C is moved over and across the reel, which movement its chain 5l will permit, after which the reel is operated to draw on the chain, all as will be readily seen. To use the machine for splicing a broken wire, the ends of the wire near their extremities are engaged in the clamps C C, and they are drawn together by manipulating the reel until they lap each other,when theyare twisted or otherwise connected, as illustrated in Fig. 2.v

The clamp C is therefore used when splicing the wires, and in such instance, as will be apparent, as the two clamps C C bite the ends of the wires the device supports itself and need not be attached to the post. When it is desired to stretch the wire along the opposite side of the post from that on which the body B stands, the set-screw ll is removed and the entire body l is turned in the blocks 10 and 30 of the post-brace and chain-tightener to bring the reel into a horizontal position, as will be clear, after which the set-screw is reengaged with another of the holes 5, which latter are so placed as to permit this, as seen in Fig. 3. In any event the finger 3l and its engaging-prongs 3la on the chain-tightener T may be passed along and rested against one face of the post to prevent said tightener from turning axially on the body l.

The parts of this improved stretcher are preferably of metal, and their sizes and shapes are such as will give the complete machine the desired strength and relative proportions of its members. It is thought that the use of the clamp C will be also apparent. The same is used to hold the wire when it is desired to disengage the clamp C and run it out on the wire to get a new bite when the latter is very slack or the clamp has reached its limit of movement.
