HENRY PRIDAY, OF I-IOUSTON, TEXAS.
WIRE-STRETCHING DEVICE FOR FENCE-POSTS.
SPECIFICZTION fo~:~ing part of Letters Patent No. 337,865, dated MIarch 16, 1886.
Application filed December 10, 1885. Serial No. 185,281, (No model.)To all whom it Mnay concern:
Be it known that I, HENRY PRIDAY, a citi-
zen of the United States, residing at Houston,
in the county of Harris and State of Texas,
5 have invented a new and useful Improvement
in Wire Stretching Devices for Fence-Posts,
of which the following is a specification, ref-
erence being had to the accompanying draw-
ings.
1o My invention hasrelation to improvements
in fence-posts; and the novelty consists of the
peculiar construction and combination of parts,
substantially as hereinafter fully set forth, and
specifically pointed out in the claims.
15 3My invention has for its objects to provide
improved means for simultaneously stretching
to an equal extent or degree the wires of a
fence located on opposite sides of one of the
posts, whereby the strain on the post will
2o be equalized and reduced to a minimum; to
provide improved means for holding the wires
in a stretched or taut condition, and permit
the stretching devices to be readily detached
and replaced in the case of breakage to the
25 parts, and to provide a device of the class
named which shall be simple and durable in
construction and cheap.
In the accompanying drawings, Figure 1 is
a perspective view of my improved fence-post.
30 Fig. 2 is a vertical longitudinal central sec-
tional view on the line x x of Fig. 1. Fig. 3
is a detached detail view of the winding-pul-
leys, and Fig. 4 is a view showing three of my
improved posts connected by wires that form
35 the fence.
Referring to the drawings, in which like
letters of reference denote corresponding parts
in the several figures, A designates the base
of the fence-post, which is tapered toward its
40 lower end, and has a helical-shaped rib, a,
formed on its exterior face, which thus pro-
vides a threaded and pointed base, which will
readily and freely enter and penetrate the
earth and be retained rigidly therein. The
45 upper end of the base has a socket, a', in which
is fitted the lower end of a shaft or upright,
B, and said shaft is secured in the socket of
the base by a tapering key or wedge, b, or by
any other preferred means.
50 C designates a number of sleeves or tubular
pieces loosely fitted on the shaft or upright,and between each adjacent sleeve are arranged
two pulleys, D E, to which the fence-wires D'
E' are secured.
Any preferred number of sleeves and pul- 55
leys may be employed, the number of pairs of
pulleys corresponding in number to the strands
of fence-wires D' E'. The sleeves may be rig-
idly secured on the shaft, or they may be left
free to havevertical and horizontal movements 60
thereon, and the pulleys are free to rotate
on the shaft to stretch and tighten the wires
D' E' when it is desired to do so.
Each end of the wire D' is secured on or to
the pulley D of two adjacent posts, and each 65
end of the wire E' is similarly secured to the
pulleys E of two adjacent posts. The pulley
D of each pair has depending lugs or shoul-
ders f, which enter seats or sockets f' in the
pulley E, or the position of the partsff' may 70
be reversed. When it is desired to stretch
and tighten the wires D' E', a wrench of any
preferred construction is fitted to the pulleys
D E to rotate them simultaneously and in one
direction or plane of revolution to draw upon 75
the ends of said wires and wind them around
said pulleys, thus effecting the operation of
tightening the wires simultaneously.
The periphery of the rollers may be notched
to receive a spanner-wrench to tighten the 80
wires, but any preferred implement or tool
may be employed for rotating the pulley.
The wire D' of each pair of pulleys is se-
cured to the upper flange of the upper pulley,
D, and the wire E', that is arranged on the op- 85
posite side of the post, is secured to the lower
flange of the lower roller, E, whereby the
strain or force exerted on the post by the wires
D' E'is brought to a point approximately com-
mon to both, to equalize the force on the post 90o
or the shaft B thereof and reduce said strain
or force to a minimum.
The upper end of the shaft B is threaded as
at g, and on this threaded end works a cap, G,
which has an interiorly-threaded socket, g', 95
the function of this cap being to exert press-
ure on the sleeves and pulleys and prevent ro-
tation or movement thereof when the wires
have been stretched.
I do not desire to limit myself to the exact Ioc
details of construction herein shown and de-
scribed as an embodiment of my invention,
