HENRY EDWARDS AND MILLARD F. SADLER, OF TROUP, TEXAS.
WIRE-STRETCHING MACHINE.Specification of Letters Patent.
Patented March 23, 1909.
Application filed May 11, 1908. Serial No. 432,180.
To all whom it may concern:
Be it known that we, HENRY EDWARDS
and MILLARD F.. SADLER, citizens of the
United States, residing at Troup, in the
5 county of Smith and State of Texas, have
invented certain new and useful Improve-
ments in Wire-Stretching Machines, of which
the following is a specification, reference be-
ing had to the accompanying drawings.
10 Our invention relates to improvements in
machines or devices for stretching wire and
for analogous purposes; and it consists of
the novel features of construction and the
combination and arrangement of parts here-
15 inafter fully described and claimed.
The object of the invention is to improve
and simplify the construction and operation
of machines .of this character and to provide
one which is simple and practical in construc-
20 tion, powerful and effective in operation,
convenient and easy to adjust and manmpu-
late and adapted for a variety of uses.
The above and other objects of the inven-
tion are attained in its preferred embodiment
25 illustrated in the accompanying drawings, in
which-
Figure 1 is a perspective view illustrating
the use of our invention in stretching a wire
fence or wire netting; Fig. 2 is a longitudinal
so sectional view through the stretcher showing
it adapted for drawing together the ends of
two wires which are to be united; Fig. 3 is a
transverse section on the plane of the operat-
ing lever; Fig. 4 is a detail transverse section
35 through the end piece 4 of the body or frame
of the device; Fig. 5 is a detail view of the
lever and the parts attached to it; and Fig. 6
is a detail transverse section through the
lever.
40 Our improved wire stretcher comprises a
body or frame 1 in the form of a substan-
tially rectangular loop composed of a U-
shaped member having side bars.2 united at
one end by a curved integral portion 3 and
45 at their opposite ends by a removable cross
piece or bar 4 which is formed at its ends with
openings to receive the side bars 2 and
which is secured by transverse bolts or simi-
lar fastenings 5. The side bars 2 of the
50 frame or body have smooth inner edges but
their outer edges are fformed with notches
which provide ratchet teeth 6, 7. In the
curved or closed end 3 of the body 1 is
formed a centrally disposed, longitudinally
55 extending opening in which is swiveled a
hook 8, and a similar hook 9 is swiveled inan opening formed in the center of the cross
piece or. bar 4. The latter has its central
part recessed upon one side, as shown at 10,
for .a purpose presently explained. 60
Mounted for sliding movement within the
frame is a pawl and lever carrying member
11 which is in the form of a substantially
rectangular plate or block adapted to slide
freely between the straight inner edges of 65
the side bars 2. This slide or block 11 is
retained in the frame by a lever 12 consist-
ing, preferably, of two similar metal strips or
plates having their central portions engaged
with each other and united by one or more 70
rivets 13 and their inner end portions 14
spaced apart and engaged with the opposite
faces of the bars 2 and block 11, to which
latter they are pivoted by a rivet, bolt, or
the like 15. The pivot 15 serves as a fulcrum 75
for the lever, which when oscillated, causes
two dogs or pawls 16, 17 to travel along
the ratchet or rack teeth 6, 7. These dogs
are pivoted intermediate their ends at 18.
between the spaced inner ends 14 of the lever 80
plates or members and they are disposed
upon the outer sides of the bars 2, 2 so as to
engage the ratchets upon the latter. Each
of said pawls has a flat inner edge, a tapered
portion or pawl proper at one end and a 85
finger piece 19 at its other end. The outer
ends 20 of the plates or members of the lever
are spaced apart and surrounded by bands
21 secured by rivets or the like 22. The
parts 20, 21 form a socket for a removable 90
handle 23 which may be used when it is de-
sired to lengthen the lever 12 to obtain
greater leverage.
When the machine is to be used for
stretching a wire, wire fencing, for moving 95
heavy objects, or for analogous purposes,
either the body or frame 1 by means of
swivel 9 or the block 11 by means of device
41 may be secured to a post or other sta-
tionary object, but we preferably fix the 100
block 11 by means of a chain or similar
flexible element 24 which has one of its
ends secured in an opening 25 in the block 11
and its other end provided with a hook 26
which may be engaged with any of the links 105
of said chain after the latter has been passed
around a post 27 or any other stationary
object.
It will be noted upon reference to Fig. 2
that by providing the recess 10 in the cross 110
bar 4 the chain 24 is permitted to extend in
a straight line from the post 27 to the blockNo. 915,753.
