WALTER L. TOMPKINS, OF FRISCO, TEXAS.
WIRE-STRETCHER.Specification of Letters Patent.
Patented Jan. 4, 1921.
Application filed May 6, 1918. Serial No. 232,731.
To all whornitrmnay concern:
Be it known that I, WALTER L. ToMnKINs.
a citizen of the United States, residing at
Frisco, in the county of Collin and State of
5 Texas, have invented certain new and useful
Improvements in Wire-Stretchers, of which
the following is a specification.
My invention relates to improvements in
wire stretchers or tighteners and has partic-
10 ular reference to a tool or device of this
character for stretching or tightening the
wire when constructing a wire fence or for
similar purposes.
The principal object of my invention is
15 the provision of a wire stretcher which, on
account of its novel construction and ar.
rangement, is unusually strong and well
adapted to wire stretching.
Another object of my invention is to pro-
20 vide a wire stretcher which is capable of
being adjusted to various heights to suit the
requirements of wire fence construction.
Other objects and advantages will be-
come apparent as the description of the in-
25 vention progresses.
Briefly, my invention consists of parallel
bars spaced apart to form a frame, one end
of which frame is forked to bear against
and partially encircle a fence post, the other
30 end of the frame being adapted to be re-
movably supported on a relatively long
pointed rod or stake which, driven into the
ground, gives the frame a firm and rigid sup-
port while the wire is being tightened. Be-
3 tween the parallel bars constituting the
frame is arranged a small drum upon which
the wire is to be wound in the stretching op-
eration and this drum is arranged to be
turned through a ratchet operated by a bar
40 or handle.
My invention will be more fully under-
stood from the following description taken
in connection with the accompanying draw-
ings forming part hereof, in which-
45 Figure 1 is a side elevational view of my
wire stretcher.
Fig. 2 is a top or plan view.
Fig. 3 is a detail view in section of the
drum and ratchet mechanism, and
50 Figs. 4 and 5 are respectively side and
plan views of the wire drawing hook.
Referring to the drawings, the frame of
the wire stretcher is composed of two sec-tions 1-1, each section being formed of
the two angle iron frames 2-2 bent in the 55
manner shown and connected at their ends
by plates 3 and centrally by plates 4. A
rod 5 connected to the central plates 4 holds
the sections 1-1 in parallel relation. The
ends 6 of each section 1 are forked as shown 60
in Fig. 2 to abut and inclose a corner of a
post when the stretcher is in position.
Attached to the opposite end of the frame
is a relatively long cylindrical rod or stake
7, the lower end pointed and shown as 65
broken apart for better illustration. This
rod or stake 7 is driven through the holes
8 in the ends of the connecting plates 3 and
into the ground and a pin placed in one
of the holes 9 in the rod 7 to support the 70
frame 1 at the proper heights. Other simi-
lar holes not shown are placed in the rod
7 at equal distances apart to allow the wire
in the fence which is being tightened to come
into alinement with the drum and cable. 75
The stretching drum is mounted to turn
upon a bolt 10 which spans the sections 1-1
of the frame, serving also to more firmly.
connect the sections. The drum is in the
form of a ratchet clutch, one member 11 of 80
which is forced under tension of a spring
14 into locking engagement with the other
member 12 on which the wire or cable is to
be wound. The ratchet teeth 13 between the
contacting faces of the clutch are in locking 85
engagement when the member 11 is turned
by the bar or lever 15 in one direction, but
the member 11 when moved in the opposite
direction rides over the teeth of the other
member, being retracted slightly against 90
tension of spring 14 to permit of this move-
ment.
A pawl 12b engaging the ratchet 12a on
drum member 12 serves under influence of
its spring 12c to prevent retrograde move- 95
ment of member 12.
Attached to the end of the wire rope or
cable 17 is a claw hook 18, the wire to be
stretched fitting into the V shaped wedge 19
which is roughened as shown to firmly grip 100
the wire. The hook 18 is fastened to the
cable 17 by a clamp 20 with bolts and nuts as
shown. The end of the rope 17 is attached
to the drum 12 preferably by a rivet 21 in
the interior 22 of the drum. 105
Having thus described the nature and ob-1,364,530.
