there is pivotally mounted a dog 1T, the
pivot pins being indicated at 18. The
wedge shaped extremity of each dog which
engages the correlated racks 4 has a greater
5 thickness than the portion of the dog which.
is mounted in the slot 10, the enlarged ex-
tremity thus formed being indicated by the
numeral 19. The other extremities of the
two dogs are formed with handles 20, "so
10 proportioned and spaced as to be simultane-
ously gripped in one hand by the operator.
By pressing the hand-holds 20 together, the
operator may simultaneously swing the two
dogs out of engagement with their respec-
15 tive racks 4.
To each dog there is connected one ex-
tremity of a chain 21, which chain passes
closely adjacent to the correlated bar 12, and
also passes through the slot 10 which is in
20 alinement with said bar 12, the chain being
carried by the correlated roller 11 in passing
through said aperture 10, the point of at-
tachment of the chain 21 to the dog 17 with
relation to the pivot bolt 18 is such as to
25 tend the force of the extremity 19 unto the
teeth 4 of the bar 1. The length of the two
chains is sufficient to permit the adjustable
frame. comprising the parts 12 and 13 to be
displaced to the handle extremity of the
30 bar 1 without drawing the ends of the same
through the slots 10. The free ends of the
two chains are respectively provided with
means for engaging a wire these means be-
ing duplicated upon each chain extremity.
35 Said means in each case comprise a hook 23
and wire clamping device 24, consisting of a
plate having a channel or groove 25 adjacent
to one lateral edge and an eccentrically
pivoted cam 26 adapted to engage a wire
40 between its rim and the bed of said channel.
In bringing the clamping device into en-
gagement with the wire, the wire is first
passed through the channel 25, and the cain
26 is rotated until its rim comes into contact
45 with the wire resting in the channel. A lon-
gitudinal strain exerted upon the wire will
tend to produce further rotation of the cam
and thus will clamp the wire more securely
in proportion as the strain upon the wire is
50 increased.
In using the tool to connect the ends of a
broken wire, the frame carrying the lever
bars 12 and pawls 17 is moved up to the
head 5 thus paying out the chains 21 where-
55 by sufficient length is given to engage the
broken extremities of the wire in the clamps
24 and leave enough of the wire ends pro-
jecting to twist together when the splice is
made. The lever bars 12 are then swung to-
co ward and from' the bar whereby the frame
is moved away from the head and the chains
pulled through the head. When the clamps
24 are drawn together the free ends of the
wire may be twisted together. It is appa-
s rent that as one of the lever bars 12.is swungoutward the correlated pawl 17 is moved
into engagement with the next tooth 4, and
when the bar is swung inward the frame is
moved away from the head 5.
In using the tool to stretch a wire, the end 70
2 of the bar 1 is suitably fastened to a post
and the head 5 directed toward the wire to
be stretched. The frame carrying the bars
12 and pawls 17 is moved up to the head 5
to pay out the chains. Only one chain is 75
used. The clamp 24 of the chain is engaged
with the wire and the lever bars 12 swung to
step the frame along, the bar 1 away from
the head and thus draw the wire -taut.. By
placing the end of a piece of pipe over the g
reduced ends 22 of the bars 12 the leverage
may be increased.
the tool may be conveniently carried on
horseback and used by fence riders. -Should
a broken or burned post :and slack wires be 85
encountered, the claw 8 is used to pull out
staples. To set a- new post the head 5 and
frame carrying bars 12 and pawls 17 are re-
moved and the bar 1 usedto dig a new hole.
After the post is set the frame and head are
replaced. To tighten the wires the operator
places.the tool horizontally with the post
received in the recess 9' of the head and the
end 2 resting against his body.. The tool is
disposed against the post at right angles to 9
the wire. and the hooks 23 engaged with the
wire on each side of the post.. By manipu-
lating the bars 12 the wire- is drawn -toward
the head 5 on each side of the post and the
slack thus taken up. These drawn or looped 100
portions of the wire may be tied by a short
piece of wire extending around the post
therebetween. Staples may be driven with
the end 7 of the head 5.
It is obvious that various changes.may be 105
made in the form and proportion of parts.of
the above described device without depart-
ing from the spirit or sacrificing the advan-
tages of the same, and the -invention is,
therefore presented as including all such 110
modifications and changes as properly come
within the scope of the following claims.
What I claim is:
1. In a device of. the character described,
the combination with an elongated bar hav- 15
ing its opposite lateral edges provided with
two racks of ratchet teeth, of a head rigidly
mounted upon one extremity of said bar, a
frame adapted to undergo adjustment" longi-
tudinally of the bar, a. pair of dogs pivot- 120
ally mounted upon said frame and respec-
tively adapted to engage the two racks of
ratchet teeth, a pair of chains each having
one extremity connected to one of the dcogs,
said chains being' -respectively passed 125
tbxough apertures provided in said heads,
and a means for engaging a wire carried at
the other extremity. of each chain.
2. In a device of the character described,
the combination with an elongated bar, hav- 1o2
