UNITED STATES HOWEL E. GLOVER, OF LONOKE, ARKANSAS.

WIRE-STRETCI-IER.

Specification of Letters Patent.

Patented Mar. 22, 1921.

Application filed August 22, 1919. Serial No. 313,258.

1 '0 aZZ 107mm it may 0012 car n Be it known that I, HowEL E. GLovER, a citizen of the United States of America, residing at Lonoke, in the county of Lonoke and State of Arkansas, have invented new and useful Improvements in WVire-Stretclr ers. of which the following is a specification.

The object of the invention is to pro vide a neat and simple device of the above mentioned character particularly designed for stretcl'iing wire fencing when applying the same to posts. The invention is of sucha character that no clamping is necessary in attaching it to the fencing and it consists of two members movable with respect to each other, each one provided with a grapple hook for attachment in the chain car led by the member which is secured to the fencing, the one being employed for holding the fencing after it has been stretched a certain amount, so that the active part of the device may be attached ire-connected for the purpose of obtaining a new hold to further stretch the fencing.

The invention isillustrated and described in a specific embodiment, to which, however, it is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claims.

In the accompanying drawings:

Figure 1 is a view in side elevation showing the apparatus in operative position.

Fig. 2 is a top plan view of the stretcher er se. i p Fig. 3 is a section on the line 3-3 of Fig. 1. i

Fig. 4c is a section on the line 1- 1 of Fig. 1.

Referring to the drawings the invention may be described as consisting of an actlve and a passive element, the passive element being in the form of a bar 1 on opposite sides of which the longitudinally disposed plates 2 are attached. The lower edges of these plates are flush with the longitudinal edges of the bar but' their upper edges extend beyond the upper edges of the bar to provide a guideway for the active element which is in the form of the bar 3. The active element or bar 3 is formed on its upper edge with the teeth 4. which are in the form of ratchet teeth, one face of each tooth being disposed at right angles to the length of the bar and the other faces of the teeth being diagonally inclined with reference to the lengthof the bar. Strap members 5 are secured to the passive element, being attached to the plates 2 and straddling the bar This construction, it will be observed, provides against any other relative movement between the two bars than longitudinal movement and this latter movement is necessary in order that the device may effect the objects for which it is designed. The bar 1 at one end carries a clevis 6 to which a chain 7 is attached this chain being designed for attachment to an anchor post such as that illustrated at 8 in Fig. 1. The bar 1 at the opposite end carries an eye 9 to which one end of a chain 10 is attached, the chain at the opposite end carrying the hook 11.

A stirrup 12 is carried by the bar 1, this stirrup straddling the bar 3 and being pivotally attached to the bar 1 on opposite sides of the plates 2 as indicated at 13. This stirrup lies *down on top of the teeth a and itscrotchportion is designed to engage the teeth on the perpendicular faces of the iatter. Thus, when the stirrup is engaged with the teeth, the bar 3 may be moved in the direction of the post 8 but is precluded from the opposite direction.

The bar 1 is connected to the anchoring post 8 by means of the chain 7. The bar, therefore, is attached to the wire fencing to be stretched and to this end there is pro vided a bar 1 1 which is preferably of wood. The wire fencing 15, at the end is bent around thisba-r 14, as clearly illustrated in Figs. 1 and t and the longitudinal strands are crossed on their bent back portion as indicated at 16 in Fig. i. The vertical strand 17 adjacent to which the bar 14: is placed precludes those portions of the longitudinal strands to which the vertical strand is attached from passing to the same side of the main portions of the longitudinal strands on which the crossed portions 1'6 stand. A pin, therefore, such as the pin 18, passed through the loops made in the longitudinal strands at 16, serves to secure the end of the fencing on the bar 14. .This bar 141 at its longitudinal center carries an appropriate anchoring hook 19 and one end of the chain 20 connects with this anchoring hook, the other end being attachable to a hook 21 attached to a clevis 22 secured to one end of the bar 3. i

A hand lever 23 carried between two plates'24: which straddle the bar 3 and are pivotally connected to the bar 1, as indicated at 25, serves as a means for effecting relative movement between the two bars when the one is attached to the fencing as has been before described and the other attached to the anchorin 30st 8 as has also been dev the 'jfencing.

scribed. The two plates 24 carry between them a pin 26 and pivotally connected to this p n are the legs of a stirrup 27' which is similar to the stirrup 12 and similarly engages the teeth l. The wire fencing 15 is slack when the device is initially attached to 1t andthe anchoring post but the stirru-p 12 engages certain of the teeth 4 and t'hestirru'p 27 certain other of the said teeth.

I movement-of the bar 3 rides over the teeth 4r and finally engages. a tooth nearer that end at which the clevis 22 is carried than it previously engaged. This relative position of the two barsis then maintained while the -lever1s shifted in the direction of the bar 14 to have its stirrup 27 engage new teeth f 30 Repeating the operation previously described results in the increase of tension on the fencing, When the fencing has been stretched so that no further movement of the bars is permissible, the hook 11 carried by the. chain 10 is engaged in one of the links of the'chain 20, whereupon the bar 3 may he released by allowing it to move back slightly in the direction of the bar 1%. This canbedoneby shifting it in this reverse direction the distance of the length of.

a 'tooth 'the hand lever 'servin to hold the bar while the stirrup 27 is lifted up and engagedrwith a new tooth farther to the right. Finally, by repeating this operation, the bar 3 is relieved of} any tension and the tension is all imposed upon the bar 1 through the medium of the hook 11 and chain 10.. The bar 3 may then be shifted in the direction of the bar 1i and the full operative length of the device is again obtained whereupon a new grip by the bar may be had by having its hook 21 cngagc certain links of the chain 20. The opcra tion of stretching fencing further may be carried on by repeating the operatir'ms bcfore described.

The invention having been described. what is claimed as new and useful is:

1. A wire stretcher comprising an active element in the form of a bar. a passive clcment with which the active element is slidably connected, the active clement being formed with teeth. a stirrup carried by the passive element and straddling thi active element and engaging the teeth thereof, a h and lever pivotally connected to the passive clcment and straddling the activc element. a stirrup pivotally connected to the lever and engaging the teeth of the active clement. an anchoring chain carried at one end of the passive element. a gapplc hook carricd at one end of the active element. a second grapple hook. and a flexible (Unfit-Flinn b.- tween said grapple hook and the opposite end of the passive element for the purpose specified.

2. A wire stretcher comprising an act ve element. a passive element with which the active element is slidahly engaged, manual means for effecting relative longitudinal movement of the two members. means for securing the two members in relatively iixcd position during the inactive period of the said manual operating means, a grapple carried by the passive element. a grapple carried by the active element. and a supplemental grapple carried by the passive element at the end remote from the first said grapple. the said supplemental grapple being flexibly connected to the active element for use during the time of changing position of the grapple carried by the active element.

In testimony whereof I affix my signature.

HOWEL E. GLOVER.
