implement of the character which can engage a fence post as a fulcrum and by proper manipulation of the lever, the wire can be appropriately stretched and retained until the wire is secured by staples or the like.
A further object of the invention is to roduce a wire stretcher that can be manipulated by inexperienced operators, said stretcher being light in weight, simple in construction. e'liicient and satisfactory in use and comparatively inexpensive to produce and maintain.
lVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying drawings, forming part of this specification wherein like characters denote corresponding parts in the several views, in which,
Figure 1, is a plan view of the stretcher in operative relation to the fence post; Fig. 2, is a similar view with the elements of the stretcher in different operative relation; and Fig. 3, is a view in elevation.
In these drawings A, denotes a fence post and B, a lever engaging the fence post. The lever has two eye bolts C and D, the former of which has the toothed rack E, pivoted to it. The toothed rack is preferably formed by utilizing a flat strip of metal and having the teeth F, struck thereon, for it has been found in practice that such an element can be produced quickly and inexpensively.
The pawl G, is pivoted to the and has a longitudinally disposed slot g, to receive the toothed rack, which slot permits the pawl to travel longitudinally of the toothed rack. The pawl is preferably eye bolt D,
formed of a strip of metal having a quarter twist at I, which causes the outer end of the pawl to stand at right angles to the inner end of said pawl. It will be observed also that the inner end of the pawl and the end of the toothed rack are pivoted on the same plane.
The outer end of the toothed rack has a hole J, to receive a link of the chain K, to 1 which the wire engaging member L, is connected.
The lever is also provided with an eye bolt M, to which the chain N, is attached, said chain having a wire engaging member This last mentioned device is utilized to stretch wire on the last panel, the lever engaging the post with the parts in a position reversed from that shown in the drawing.
The lever is also arovided with a loop P, having an anchoring rod Q1, loosely connected to it, said anchoring rod being adapted to have its end embedded in a post in order that said lever may be held at the proper elevation on the post while it is manipulated, thus insuring a proper position ing of the wires with relation to one another and with relation to the extremities of the posts.
e claim:
1. A wire stretcher comprising a lever, a toothed bar and a prop, both loosely connected to said lever, in alinement one with the other, said prop having a longitudinal slot for the reception of said toothed bar, with one end wall of said slot engaging the outer longitudinal edge of said bar and the other end wall of said slot adapted to engage the toothed edge of said bar.
2. In a wire stretcher, a lever, eye bolts therein, a toothed rack pivoted to one eye l bolt, a pawl pivoted to the other eye bolt, said pawl comprising a strip of metal twisted intermediate its length and having its l l l outer end standing at right angles to its l inner end and slotted to receive the toothed rack, and a wire engaging device connected l to the toothed rack.
l 3. A wire stretcher comprising a lever, a toothed bar and a pawl, said latter members having p1votal eye bolt connectlons w1th 1 said lever in alinement one wlth the other, 1 said pawl member having its outer portion at right angles to its inner portion and protures in the presence of two witnesses this vided With a longitudinal slot receiving said 19th day of May, 1908.
toothed bar member edgewise, With one end I Wall of said slot adapted to engage one 1011- gg ls i gitudinal edge of said toothed bar member J x and the other end Wall of said slot adapted Vitnesses:
to engage the toothed edge of saidbar. P. N. SPRINGER,
