in the manner illustrated in Fig. 1, for the
purpose of drawing said wire across the ad-
jacent side of the post preparatory to secur-
iug the wire by means of staples in the ordi-
3 nary manner.
In order to anchor or secure the machine to
a post, the frame is provided with a laterally-
extending eye 14, to which is connected one
end of an anchoring-cable 15, the opposite
[o end of which is provided with a grappling-
hook 16, having a pointed bill or extremity
adapted to enter and positively engage the
surface of the post, as illustrated in Fig. 1.
In order to lengthen or shorten the anchoring-
15 cable 15, so as to accommodate the machine to
posts of different diameters, I provide a take-
up hook 17, which is connected to the eye 14
directly or by means of the first link of the
anchoring cable or chain or, in other words,
20 the link which is directly associated with the
eye 14. The hook 17 may be engaged with
any one of the links of the anchoring chain
or cable, and in this way the length of the
chain may be regulated to suit the size of the
25 post with which the grappling-hook is to be
engaged.
The end bars of the windlass-frame are each
provided with integral lateral extensions 18,
which are notched, as shown at 19, to receive
3o the fence-wires and enable the barbs thereof
to be engaged behind or within the end bars
of the windlass-frame. By reference to Fig.
3 it will be seen that the claws or wire-en-
gaging extensions 18 project from opposite
35 sides of both end bars, so that the machine
may be used either side up, and any particu-
lar fence-wire may be engaged with the claws
at one side or the other of the machine, thus
adapting the machine to be used by either
40 right or left hand operators.
The windlass-shaft 10 is equipped with a
pair of ratchet-wheels 20, one of such wheels
being arranged at each end of the windlass-
shaft and just inside of the side bars of the
45 windlass-frame, as shown in Fig. 1. Each of
the ratchet -wheels has formed integrally
therewith a guard-flange 21, the diameter of
which is materially greater than the ratchet-
wheel, and said flange is provided upon the
50 side opposite the ratchet-wheel with a dia-
metrical rib 22, having a longitudinal open-
ing in which is received a removable pin or
key 23, which is adapted to pass through an
opening 24, extending transversely through
55 the windlass-shaft 10. By the construction
described the teeth of the ratchet-wheel 20
are housed between the guard-flange 21 and
the disk-shaped bearing 11 of the frame, thus
preventing the stretching-rope 7 or the an-
Go choring-cable 15 when not in use from becom-
ing caught by and engaged with the ratchet-
teeth, which would render said ratchet-wheels
ineffective. Associated with each of the
ratchet-wheels 20 is a pawl or detent 25, piv-
G5 otally mounted, as at 20, upon the inside of
one of the side bars of the windlass-frame.The teeth of one ratchet - wheel are dis-
posed reversely to those of the other ratchet-
wheel and the pawls are correspondingly ar-
ranged so that the windlass-shaft may be held 70
from rotating, irrespective of the direction in
which the stretching-cable is wound thereon.
The operating-handle 27 may be of any suit-
able construction; but as it is necessary to
equip the machine with wire-twisters, wire- 75
cutters, staple-pullers, and post-trimmers I
have illustrated the operating-crank in the
form of a combination-tool, in which the crank
constitutes the handle of the implement and
is provided at one end with a detachable 8o
crank-handle 28. The tool also comprises a
hatchet-blade 29 for trimming the bark from
the posts, a n ire-cutter 30, a staple-puller 31,
a tying or twisting fork 32, and claws 33 for
engaging the overlapping ends of a broken 85
wire for the purpose of twisting said over-
lapping ends together and forming a strong
tie or joint. The combination-tool consti-
tuting the operating-crank and illustrated
separately in Fig. 5 will, however, form the 90
subject-matter of another application and
will not be described in detail herein.
In utilizing the machine for hoisting pur-
poses the stretching-cable 7 is led over one or
more overhead pulleys 34, hung from a cell- 95
ing or other suitable support, and said cable
is provided with a terminal ring 35, receiving
a loop 36, which may consist of a rope, cable,
or chain. The loop 30 is passed around one
end of the object to be elevated, as shown in 1o
Fig. 2, while the horn or hook 2 of the frame
is engaged under the opposite end of the ob-
ject. By means of the operating-crank 27
the cable 7 is wound upon the windlass-shaft
or unwound therefrom, and in this manner 105
the wagon or other object (indicated at 37)
may be raised and lowered at will.
As the operation of machines of this class
is well understood, it will not be necessary to
enter into a description thereof. It will be itd
noted that by means of the construction de-
scribed the stretching-cable as it is wound
upon or unwound from the windlass-shaft is
prevented from coming in contact with the
teeth of the ratchet-wheels 20 or the engag- 115
ing extremities of the pawls or detents 25,
thus avoiding the liability of the machine to
slip by the accidental release of the windlass-
shaft. The guard-flanges 21, together with
the enlarged bearings 11 of the machine- 120
frame, prevent the stretching-cable 7, as well
as the anchoring-cable 15, from interfering
with the teeth of the ratchet-wheels, thus
curing a defect which has hitherto been pres-
ent in all machines of the class referred to. 125
It will further be seen that by the arrange-
ment of reversely-extending claws 18 the ma-
chine may be used either side up and by
right and left hand persons with equal facil-
ity; also, that the anchoring-cable may be 130
lengthened and shortened, as occasion may
require. The operating-crank 27 is provided2
