HARRY R. BOOZE, OF BUCHANAN, VIRGINIA.

WIRE-STRETGHER.

Specification of Letters Patent.

Patented ct. 17, 1911.

Original application led .Tune 14, 1910, Serial No. 566,794. Divided and this application filed October 1, 1910. Serial No. 584,891.

To all whom tt may concern:

Be it known that I, HARRY R. Booze, a citizen of the United States, residing at Buchanan, in the county of Botetourt and State of Virginia, have invented certain new and useful Improvements in Wire- Stretchers, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in wire stretchers and has for its object to provide a very simple and ethcient device of this character which may be easily and quickly arranged in position upon a fence post to properly stretch the wires preliminary to the stapling of the same to the fence post.

Another obj-ect of the invention is to provide a wire stretcher which is adapted for use in combination with a fence wire clamp, the stretcher being arranged upon a fence post and consisting of two primary elements, one of which is engaged with the chains connecting the upper and lower ends of the clamping bars and is pivotally movable upon the other member, and means for holding the iirstnamed member against retrograde movementI after the wires have been stretched.

A still further object of the invention resides in the provision of a very strong and durable wire stretcher which may be constructed at a low cost.

With these and other objects in view, the invention consists in the improved combination and arrangement of parts hereinafter fully described and claimed and illustrated in the accompanying drawing in which is shown a perspective view of my improved wire stretcher arranged in operative position.

Referring in detail to the drawing 5 indicates the wire clamping bars which are adapted to be arranged upon opposite sides of the fence wires W. The manner in which these bars are connected and clamped together upon the fence wire forms the subject matter of a prior application for patent tiled by me J une 14th, 1910, Serial Number 566,794, and of which this application is a division. It will suliice for the purposes of this description to state that these bars are connected together at their upper and lower ends by means of a link chain C which is adapted to be engaged by my improved stretching device in a manner which will be more fully hereinafter set forth.

The wire stretcher embodied in the present application comprises a main body bar y 10 which is arranged adjacent to thefence post P. At one end this bar has an enlargement 11, said end portion being rectangular in form as shown at 10 while the remaining port-ion thereof is preferably cylindrical. To the end of the cylindrical portion of the bar a hook l2 is secured which is adapted to be engaged with the meshes of the fence wire fabric to support the end of the bar when the stretcher is arranged in operative position. Adjacent to the other or forward end of the bar 10 an arm 13 is secured, said arm being bifurcated at its outer end to form gripping iingers 13. These lingers are adapted to engage and bite into the fence post l). Upon the enlarged end 11 of the bar a U-shaped member 14: is pivoted upon the pin 15 which extends vertically through the end of said bar. The U-shaped yoke member 141 is formed of two heavy metal bars or arms 14 which are brought together at one of their ends and connected by the bolts or other analogous fastening devices 16. rIhese bolts also extend through the ends of the loops 17 which are disposed upon opposite sides of the yconnected arms 111. The other ends of the yoke arms extend upon opposite sides of the end of the bar 10 and beyond the edge thereof and have their extremities formed with the hooks 18.

In the. loops 17 the end of a lever or handle 211 is inserted by means of which the yoke member 14 may be turned upon its pivot pin 15, the hooks 1S on the ends of a yoke being engaged with the chains C whereby the clamp in which the fence wire fabric is disposed is pulled or extended forwardly beyond the post and the wire stretcher. This pull upon the clamp also serves to bind the opposed edges of the clamping bar upon the tence wires and thus overcome all liability of the wire slipping between the bars.

The enlarged end portion 11 of the bar 10 is provided with a plurality of openings 25 any one of which is adapted to receive a pin 26. These openings are arranged in circular series and the pin 26 is inserted therethrough in advance of the yoke arms 14 after the wire has been stretched, to retain the yoke in position upon the bar l0 and prevent its retrograde movement, thus preventing slackening of the fabric and permitting the operator the free use of his hands in the stapling of the Wire to the fence post. The hooks 18 are then disen- V gaged from the chain and the stretcher removed. IThe clamp is then positioned upon the fabric adjacent to the next succeeding fence post and the same operation repeated.

From the foregoing it will be seen that I have produced an extremely simple and eiiicient wire stretcher whereby the wires of a fence may be very quickly stretched and stapled to the post. The bar l0 and the parts carried thereby may be moved to any position upon the post so as to stretch the wires both at the top and bottom thereof, thus preventing any portion of the fabric from sagging or giving under severe strains. The device is also capable of quick application so that its arrangement in operative position upon the fence post requires but little time, thus greatly lessening the expense and labor involved in the erection of the fence. The stretcher is also extremely durable and may be manufactured at a comparatively low cost.

While lf have shown and described the preferred embodiment of my invention, it will be Vunderstood that the saine may be variously modified without departing from the essential feature or sacrificing any of the advantages thereof.

It will be noted that by means of a wire stretcher constructed as above described, t-he wires may be held tant and stapled to the same post upon which the stretcher is arranged.

secured to the yoke, an operating member insertible into said loops whereby the yoke is actuated in one direction, and means adjustable in the end of the bar tobe engaged by said yoke to prevent its retrograde movement after the wire fabric has been stretched.

2. A wire stretcher comprising in combination, a body bar, an element fixed to said bar to engage a stationary object to anchor said bar, a hook secured to one end of said bar to engage the wire fabric, a yoke j j member extending upon opposite sides of the bar at the other end thereof, apivot bolt extending through said bar and the yoke member, hooks formed upon said yoke member, means carried by said yoke member for n g the connection of an actuating element thereto, said body bar having a plurality of openings therein, and a pin insertible in any one of said openings to prevent retrograde movement of the yoke member after the fabric has been stretched.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
