We GEORGE SONNENTHAL of 85 Queen Victoria Street in the City of London
Engineer trading as Selig Sonnenthal & Co and WILLIAM KEEN of Summertown in
the Parish of Wandsworth Engineer do hereby declare the nature of our invention
for IMPROVEMENTS IN PIPE WRENCHES OR APPARATUS FOR TURNING CYLINDRICAL
OBJECTS, to be as follows:
The object of our invention is to provide a handy powerful, light and durable
tool having greatly increased range of usefulness and application and designed to
obviate the necessity for providing a series of wrenches or implements for effecting
the rotation or turning of pipes or cylindrical objects of different degrees of
thickness or diameters.
This we effect by constructing our improved wrench of two hooked or clasping
pieces of flat or somewhat flat or thin cross section pivotted to one or other of a
series of holes formed in a flat sided or square end of a bar or lever and turning
upon a pin, bolt or axis passed through all three pieces and secured by screw nut,
and this bolt may be applied at either hole in the lever as the distance between
the end of the lever and the clasping piece or pieces may require to be adjusted to
different diameters of pipes or objects to be rotated. This end of the lever which
cooperates with the clasps to grip the pipe is formed with a series of teeth,
indentations or serrations upon a curve of somewhat parabolic form and this lever
may be connected so to cooperate with the clasps when the curve of teeth is
towards or from the body of the hook or bodies of the hooks or clasps, and yet be
available for use and may be used to cooperate with both hooks or clasps or with
one only the other being turned back alongside of the lever out of the way
facilitating use in a confined or narrow space.
The inner surfaces of the clasps may be roughened serrated or of uneven contour
to better aid holding the object.
The whole when made of steel with hardened teeth forms a light very powerful
useful and durable implement.

We GEORGE SONNENTHAL, of 85 Queen Victoria Street, in the City of
London, Engineer, trading as Selig, Sonnenthal & Co and WILLIAM KEEN, of
Summertown in the Parish of Wandsworth, Engineer do hereby declare the
nature of our invention for IMPROVEMENTS IN PIPE WRENCHES OR APPARATUS
FOR TURNING CYLINDRICAL OBJECTS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of our invention is to provide a handy, powerful, light and durable
tool, having greatly increased range of usefulness and application and designed to
obviate the necessity for providing a series of wrenches, or implements, for effecting
the rotation, or turning, of pipes or cylindrical objects of different degrees of
thickness, or diameters.
This we effect by constructing our improved wrench substantially as illustrated
in the accompanying drawing in which Figure 1 shews a side view and Figure 2
an edge view of the implement constructed with the curve of teeth A¹ in one
direction, and Figures 3 and 4 with them in another direction consisting of two
hooked, or clasping pieces B B¹ of flat or somewhat flat, or thin cross section
pivotted at C or to any one, or other of series of holes C, C¹, C', formed in a flat
sided or square end of a bar A, or lever and turning upon the pin, bolt or axis C³
passed through all three pieces B, A, B¹, and secured by a screw nut C³ and this
bolt C may be applied at either hole C, C or C³ in the lever A. as the distance
between the end of the lever A¹ and the clasping piece B or pieces B, B¹ may
require to be adjusted to different diameters of pipes, or objects, to be rotated.
This end of the lever C¹ which cooperates with the clasps B, B₁, to grip the pipe is
formed with a series of teeth A¹ or indentations, or serrations, upon a curve of
somewhat parabolic form and this lever A may be connected so to cooperate with
the clasps B, B¹ when the curve of teeth is towards the body of the hook B as in
Figures 1 and 2, or from the body of the hook or bodies of the hooks or clasps as
shewn in Figures 3 and 4 and yet be available for use and may be used to operate
with both hooks or clasps B, B¹, or with one only B, the other B¹ being turned,
back alongside of the lever A out of the way facilitating use in a confined or
narrow space.
The inner surfaces of the clasps B, B¹ may be roughened serrated or of uneven
contour to better aid holding the object.
The whole implement when made of steel with hardened teeth forms a light
very powerful, useful, and durable implement.

page_text: Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
1. The construction and use of a Pipe wrench or implement for gripping and
turning cylindrical objects and operating as set forth.
Dated this 12th day of October 1885.
