BEAUMONT, TEXAS, A CORPORATION OF TEXAS.
PIPE-WRENCH.Specification of Letters Patent.
Patented.Feb. 16, 1915.
Application filed April 8, 1914. Serial No. 830,455.
o al .wkrwo U(it may concern:
Be it known that I, Guy V. IEXwIs, citizen
of the United States, residing at Caddo, in
the parish of Caddo rand State of Louisiana.,
5 have invented certain new and useful Im-
provements in Pipe-Wrenches, of which the
following is a specification.
My invention relates to pipe wrenches and
particularly to that form of wrench wherejit
.t the pipe engaging element are formed of a
plurality of sections pivotally connected to
each other and pivotally connected to the
handle of the wrench at one end.
The primary object of my invention is the
15 provision of a wrench of exceedingly simple
- character having few parts and which may
be readily- applied to a pipe or detached
therefrom.
A further object is to so form the wrench
20 that it will have a relatively large area of
contact with the pipe and will not act to
crush the pipe or puncture it..
A further object is to do away with the
necessity of using bushings in order to adapt
26 the wrench to pipes of different sizes.
Still a further object of the invention is
to provide a wrench of such simple con-
struction that it may be readily repaired in
case of any breakage, and in which the pipe
30 engaging sections of the wrench may be
made of relatively heavy material so as to
stand a great strain.
Other objects will appear in the course
of the following description. My invention
05 is illustrated in the accompanying drawings
wherein:
Figure 1 is a perspective view of a wrench
constructed in accordance with my inven-
tion, the jaws being open. Fig. 2 is a like
G0 view to Fig. 1 but showing tue jaws closed
upon a pipe.
Corresponding and like parts are referred
to in the following description and indi-
cated in all the views of the accompanying
45 drawings bythe same reference characters.
Referring to these drawings, it will be
seen that my improved wrench comprises a
handle 2 which is of any ordinary construc-
tion and which near one end is recessed as at
50 3, the outer wall of the recess being defined
by a hook 4 having a straight inner face, the
end of the handle at the hooked extremity
thereof being slightly rounded.
Pivoted to the handle 2 by means of a bolt
15 5 outward of the recess 3 are the spaced links6. A bolt or rivet 7 passes through the
outer ends of these links and has pivotal en-
gagement with an arcuate pipe gripping
section- 8. . This pipe gripping section 8 in
turn is formed at its extremity with a perfo- 60
ration';through which a pivot bolt or rivet 9
passes whereby this arcuate section 8 is con-
nected to a pair of spaced links 10. These
spaced links 10 are in turn pivoted by means
of a bolt 11. to an arcuate pipe gripping sec- 65
tion 12. the extremity whereof is recessed as
at 13, the outer wall of this recess being de-
fined by a hook 14, the inner face of this
hook being straight while the opposite face
of the recess 13 is slightly curved so as to fit 70
the face formed on the inner extremity of
the. handle 2. The interior faces of the sec-
tions 8 and 12 are toothed or otherwise
formed so as to secure a thoroughly good
grip upon the pipe to which the wrench is 75
applied.
The operation of my invention will be
obvious Co those skilled in the art. The sec-
tions 8 and 12 being pivoted to each other
and pivotally connected to the handle 2 O
may be readily opened and then caused to
embrace the pipe. The hook 4 is then en-
gaged with the hook 14- and upon a move-
ment of the handle in the direction of the ar-
row, 'Fig. 2, the two sections 8 and 12 will 8E
be drawn toward a position of eccentricity
with relation to each other and the two sec-
tions will be forced toward each other at the
same time.- Of course it will be understood
that the sections 8 and 12 do not shift into 4C
a position of actual eccentricity because of
the presence of the pipe between the sections
which will prevent this movement but the
action of turning the handle in the direction
of the arrow will tend to draw these sections
into this position and cause them to bind
upon the pipe.
It is pointed out that the arcuate sections
8 and 12 will practically contact with the
pipe of a. g-en diameter throughout its 3Cy
whole extent and that the strain will be ap-
plied to the pipe evenly. One portion of
the pipe, therefore, will not be subjected to
a greater pressure or greater strain than
another portion of the pipe in the same 105
plane. Thus as the strain is equal, there
will. be no tendency to crush the pipe or
puncture it as is the case where ordinary
pipe tongs are used. It will further be seen
that the curved face 4 on the extremity 1101,128,4u37.
