11 so that the line of strain or draft will be
straight.
It will be understood that the machine
may be otherwise anchored by any -suitable
5 means.
Chain 28 similar to the chain 24 is pro-
vided for temporarily: ainchoring the body or
frame 1 after the dogs have traveled lron
one end of the ratchets to the other and it is
10 desired to have the dogs take a further grip
upon the latter to continue the stretching
operation. This chain 28 has one of its ends
provided with a hook 29 and its other end
engaged with the.swveled hook 9. It will
15 be noted that this hook 9 has its mouth al-
most closed so. that there will .be little likeli-
hood of the chain 28 becoming disconnected.
30 denotes .a connection for use when it is
desired to stretch wire .fencing, as shown in
20 Fig. 1. This device 30 consists of a chain
having at one endi a loop 31 to detachably
engage the swiveled hook 8 and at its other
end a ring 32 to which are connected two
branch chains 33, 34 which have upon their
25 free ends:hooks 35. The latter are adapted
to be engaged with a clamp 36 of any suit-
able form and construction arranged upon
the end of the wire fencing 37 that is .to be
stretched. As shown, this clamp 36 con-
30 sists of two strips of wood engaged with the
opposite faces of the wire fencing 37 and
secured thereto by nails, bolts, or other
fastenings. The hooks 35, which are rec-
tangular in form, are passed around the op-
35 posite side faces of said clamping strips at
points suitably distant-fromtheir center, as
clearly shown in Fig. 1.
When a.single fence wire or the like is to
be stretched,-.we preferably employ a wire
40 clamp 38 which is swiveled at 39 upon a loop
40 which is adapted to be engaged with the
swiveled hook 8 in place of the loop 31.of the
device 30. The clamp 38 may :be of any
suitable form and construction, but as illus-
45 trated, it comprises a body shapedto provide
a stationary clamp jaw and a pivoted cam or
eccentric which forms the movable clamp
jaw.
When the machine is.to be used for draw-
50 ing together the ends of two wires which are
to be united, we employ the clamp 38 for
use upon one of the wires and a similar
clamp 4-1 for use upon the other wire, as
clearly shown in Fig. 2. The clamp 41 is
55 swiveled at 42 upon the outer end of a rod
43, -which latter has its other end swiveled
in an opening 44 in the block .11 by bending
said other end at right angles, passing it
through the opening 44, and heading or up-
60 setting said end, as clearly shown in the
drawings.
- In operation,.assuming the parts to be in
the-position shown in Fig. 1, when the lever
is moved in one direction, .one of the dogs
65 will ,engage one of the teeth of its ratchetso that the body 1 and the block or slide 11
will move longitudinally in opposite direc-
tions while the other dog will shp backward
-upon its ratchet to engage the next tooth.
When the lever is oscillated in the opposite 70
direction, the last mentioned dog will be
stationary while the first imentioned one will
imove backward upon its ratchet to engage
the next tooth thereof. By thus oscillating
the lever, the body or frame 1 and the block 75
or slide 11 will be caused to move along each
other. After the (logs have moved fioii
one end of their ratchets to the other
and the block 11 is at the closed end 3 of the
body 1, the chain 28 which is attached to the SO
hook 9 on the body is passc(1 around the
post 27 afn(l its hook 29 engaged with one of
its links so as to anchor the body 1. Th'1'
handles 19 of .the (logs are then pressed iin-
wardly to (lisengage them from their ratchet s 85
so that the l.)lock 11 may be moved to the
other end of the body 1. When the latter
is (lone the chain 24 is tightened (and the
above described operation repeated. 1\hei -
a fence wire is to be stretched the wire hlp 90
38 is substituted for the connection 30 and
when the ends of two wires are to be rough t
together and united one wire is connected
to the clamp 38 an(l the other wire to the.
clamp 41. 95
While we have mentioned a few of the uses
of the machine it will be understood that it
may be used in various other ways, fo
example, for moving heavy inachimery
through short distances, for pulling iron 100
safes and other heavy loads ill) inclined
planes, as into wagons, etc., for erecting and
putting into position heavy timbers in build-
ings, bridges, etc., for erecting smoke stacks, -
for straightening up storm shaken telephone 105
poles, etc.
Having thus deseribed.our invention what.
we claim is:
1. A wire stretcher comprising a U-shaped
body having a closed end and spaced side 110
bars, the latter being provided with ratchet.
teeth, a cross bar havingopenings at its ends
to receive the side bars of the body, its inter-
mediate portion having in one side an offset
and a central opening, a chain connection 115
swiveled in the last mentioned opening,
transverse fastenings uniting the ends of
the cross bar to the side bars of the body, a
block slidable between the side bars of the
body, a chain connected to said block and 120
adapted to extend through the offset in the
cross bar, a lever having at its inner end
spaced plates to receive said block and the
sidle bars of the body between them, said
plates being pivoted intermediate their ends 125
to the block, whereby the latter will le
retained in the body and the lever will be
fulcrunmed, and pawls pivoted between the
spaced plates of the lever and adapted to
engage the ratchet teeth on said side bars. 130
