LAWSON IIENREY DOWELL, OF WALTON, ASSIGNOR OF ONE-HALF TO DANIEL
R. MURCHISON, OF ATHENS, TEXAS.
WIRE STRETCHER AND SPLICER.
SPECIFICATION forming part of Letters Patent No. 490,070, dated January 17, 1893.
Application filed October 1, 1890. Renewed December 14, 1892. Serial No. 455,174. (No model.)To all woions it 7ncy concer :
Be it known that I, LAwsoN IIENREY DOW-
ELL, a citizen of the United States, residing
at Walton, in the county of Van Zandt and
5 State of Texas, have invented a new and use-
ful Wire Stretcher and Splicer, of which the
following is a specification.
My invention relates to improvements in
wire stretchers and splicers, and has for its
io object the stretchingof the wire when afence
is being constructed, the tightening of the
wire after the fence is constructed, and the
splicing of broken wire, and it consists in cer-
tain features of novelty to be hereinafter de-
5 scribed and then particularly pointed out in
the claims.
In the accompanying drawings: Figure 1
shows the device in perspective, as used in
stretching wires. Fig. 2 is a bottom plan view,
20 showing the bottom of the casing removed.
Fig. 3 is a longitudinal section on the line
3-3 of Fig. 2.
The casing of the device consists of a top
plate 1, bottom plate 2, and sides 3, 4 formed
25 by a single bent up plate, the middle of which
forms one end 5, and the inturned ends the
other end 6. The plates are connected by
corner bolts 7.
S is a staple at the end 5 on which are piv-
30 oted the pair of inwardly presented hooks or
grapplers 9 which engage the post 10.
Sliding on the top plate 1, and guided by a
lug 12, projecting therefrom, which extends
through a slot 13, is a plate 11 which is pro-
35 vided with an anvil plate 14.
15 is a cam-lever pivoted eccentrically at 16
to the plate 11 and having at its inner end a
toothed cam 18, the cam being directly oppo-
site the anvil plate so that when the lever is
40 turned toward the right the teeth of the cam
will engage a wire passing over the anvil plate.
Pivoted on each side of the lug 12 of slid-
ing plate 11 are ratchet-bars 18", 18b that ex-
tend rearwardly through openings in the end
45 5. Each ratchet bar of the pair is alternately
engaged by devices now to be described.
20 is a bolt or pin extending through the
top and bottom plates of the casing, and be-
tween the ratchet-bars, on which is fulcrumed
50 between its ends and above said bars thethrow-lever 21 that extends through slot 22
in side 3. On one side of the pivot bolt, the
throw-lever carries a pivoted link 23, and on
the other side of the pivot another pivoted
link 23a. To these links 23, 23", are piloted 55
the pawls 24, 24", respectively, the ends of
which engage the teeth of the ratchet-bars,
being thrust into engagement therewith by
springs 25.
26 is an eccentric shaft extending trans- 6o
versely through the casing and having atone
end the releasing lever 27. I call this a "re-
leasing-lever" because when turned down it
causes the eccentricof its shaft to act on and
disengage the pawls from the rack-bars. 65
28 is another anvil-plate.
29 is the lever of another toothed cam 32
pivoted eccentrically on a thumb screw 30.
The anvil plate 14, and cam-lever 15, I de-
nominate the straining or tightening clamp, 70
and the anvil-plate 28, and cam 31, the hold-
ing clamp.
The operation of the device so far as de-
scribed is as follows. A wire 33 being passed
between the anvil-plate 14 and cam 18 of the 75
straining clamp, the lever 15 is thrown to the
left which brings the teeth of the camn in en-
gagement with the wire. The throw lever 21
being grasped and reciprocated by one hand
the pawls 24,24", will alternately engage the 80o
teeth of ratchet-bars 18, 18" respectively, each
movement of the lever drawing the sliding
plate 11 toward the post and straining or tight-
ening the wire. When the slide reaches the
limit of its movement in its straining direc- 85
tion, the lever 29 of the holding clamp is
turned to the right to bring the teeth of its
cam into engagement with the wire, and thus
nip or clamp it against the anvil plate 28. The
cam lever 15 being now thrown to the left, the 90
slide may be slid to its operative position,
and the wire be further strained if desired.
I will now describe the splicer or twister.
34 is an arm projecting from the anvil-plate
28, which has at its inner end a vertical cy- 95
lindrical housing 35.
36 is a revoluble sliding stem having at its
lower end a hook 38. The upper end of the
stem is bifurcated, and extending across the
bifurcations or forks is a pin 39. oo
