WILLIAM I. MORROW, OF PINE GROVE, TEXAS.
WIRE-STRETCHER.
SPECIFICATION forming part of Letters Patent No. 572,349, dated December 1, 1896.
Application filed May 28, 1895, Serial No, 551,015, (No model,)To all won it may concern:
Be it known that I; WILLIAM I. MORROW,
a citizen of the United States, residing at Pine
Grove, in the county of Henderson and State
5 of Texas, have invented a new and useful
Wire-Stretcher, of Which the following is a
specification.
The invention relates to improvements in
wire-stretchers.
1o The object of the present invention is to
improve the construction of wire-stretchers,
and to provide a simple and inexpensive one
which will be strong and durable and which
will enable fence-wires to be readily stretched
15 for securing them to fence-posts and for con-
necting the ends of a broken wire.
Another object of the invention is to pro-
vide simple and efficient means for twisting
the terminals of a broken fence -wire to-
20 gether for connecting them, and also to en-
able a wire to be readily severed when desired.
The invention consists in the construction
and novel combination and arrangement of
parts hereinafter fully described, illustrated
25 in the accompanying drawings, and pointed
out in the claims hereto appended.
In the drawings, Figure 1 is a perspective
view of a wire-stretcher constructed in ac-
cordance with this invention. Fig. 2 is an
30 enlarged sectional view of the sliding frame,
the section being taken longitudinally of the
wire-stretcher. Figs. 3 and 4 are enlarged
detail sectional views illustrating the con-
struction of the twisting device.
35 Like numerals of reference indicate corre-
sponding parts in all the figures of the draw-
ings.
1 designates a ratchet or rack bar provided
on its upper face with teeth, and having slid-
40 ing on it a frame 2, provided with antifric-
tion-rollers and carrying a cog-wheel 3 for
meshing with the teeth of the rack-bar. The
sliding frame 2 is constructed of a single
piece of metal, and consists of parallel sides
45 and a bottom piece arranged beneath the
rack-bar.
The pinion, which meshes with the teeth of
the rack-bar, is located beneath the parallel
sides of the frame 2, and is mounted on a
50 shaft 4, which is extended and bent to form
a crank-handle 5, whereby the wire-stretcher
is operated.The rack-bar is provided at one end with
chains 6 to enable it to be readily secured to
a post or to be connected with one of the ends 55
of a broken wire when desired. The sliding
frame is provided with a link or bail 7, to
which is connected a clamp 8, adapted to be
secured to or connected with a fence-wire,
and as the sliding frame is advanced along 60o
the rack-bar by the rotation of the gear-
wheel it is automatically locked against re-
trograde or backward movement by a pivoted
pawl 0.
The pawl 9 is arranged between the paral- 65
lel sides of the frame 2 and is pivoted at 10
at one end, and its other end is extended be-
yond the frame 2 and depends from the top
thereof at an inclination and is arranged to
engage the teeth of the rack-bar. This pawl 70
is provided with a projecting handle 11, and
it has intermediate of its ends a blade 12, ar-
ranged to cooperate with a notch 13 of one
side of the frame 2 to severa wire. Thenotch
13 forms a shoulder or stop for the wire to be 75
severed, and by forcing the pivoted pawl
downward the blade is carried into contact
with the wire and is adapted to sever the same.
The rack-bar is provided at one end with
a clamp 14, having a pivoted member 15, and 80
adapted to engage a fence-wire similar to the
clamp S of the frame 2 when it is desired to
connect the two portions of a broken wire.
The clamp 14 is adapted to coOperate with
the clamp 16 of one of the chains 6 when it 85
is adapted in the process of stretching to ob-
tain a fresh hold on the wire without losing
any of the acquired tension. After the ends
of a wire have been drawn together they may
be readily connected by a twisting device 90
consisting of a vertically-disposed shaft 17,
mounted in a cylindrical sleeve or bearing 18
of the frame 2 and provided at its upper end
with a hook 19 for engaging the ends of the
wire. The sleeve or bearing 18 is formed in- 95
tegral with the frame 2 and is provided at its
top with an annular recess or enlargement of
its bore or opening to enable the wire to be
drawn into it, as illustrated in the drawings,
to facilitate twisting. A crank-handle 20 is Ioo
detachably secured to the lower end of the
shaft or spindle 17, and is adapted, when not
in use, to be held by a key 21, which is sub-
stantially T-shaped, being composed of a stem
