I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
The special object of the invention is to make a plumber's tool-stock which
shall, by a simple change of jaws, serve as a monkey-wrench, a pipe-wrench or a
pipe-cutter.
The tool-stock consists of a handle and a fixed jaw. The handle has a metallic
head with a slot, in which turns a ratchet-wheel. This ratchet-wheel is on a
post journalled in the end of the handle and having a square upwardly-extended
end, fitting a square opening in the flange of the fixed jaw. Integral with the
post are the ratchet-wheel aforesaid, a dist and a threaded end or stud, on which
screws the cap-nut. Through the handle head and on each side of the handle,
project into slot aforesaid, a pair of detents which are held to the ratchet-wheel
by springs. When the detents are pulled back with the fingers from the outside,
the fixed jaw may be placed in any desired position with respect to the handle.
open
In the fixed jaw is a rectangular hole, through which slides the threaded shank
of the movable jaw, the said shank being moved by a circular thumb-nut, which
rotates on the shank in a groove in the fixed jaw. The shank is only threaded
on the top and bottom sides, while both the other sides are grooved. The
movable cutting jaw and the backing plate therefor are provided with slots
at the bottom, and the sides of these slots are provided with studs, which work
in the grooves in the movable jaw shank. A spring presses the backing plate
against the movable cutting jaw. Each of the movable jaws has a cutter, con-
caved to give a suitable bearing on the tube and notched at the middle to take
a good bite on the metal.
The movable jaws, backing plate and spring therefor may be quickly removed
and a pipe-wrench or nut-wrench jaw substituted. Thus it will be seen that the
plumber will need but one tool-stock, (which is necessarily a heavy article) with
its attachments for three purposes, thus rendering it unnecessary to carry about
with him two out of three of the ordinary stocks.

Improvements in or appertaining to Wrenches and Pipe Cutters.
A communication from abroad by MINER ELLSWORTH WORDEN, of Scranton, in
the County of Lackawanna, State of Pennsylvania, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The special object of the invention is to make a plumber's tool-stock which
shall, by a simple change of jaws, serve as a monkey-wrench, a pipe-wrench or a
pipe-cutter.
In the drawings :-
Figure 1 is a perspective view showing the stock as used to cut pipes.
Figure 2 is a horizontal section through the handle-head to show the detents with
their springs.
Figure 3 is a cross section through jaw and handle.
Figure 4 is a detail view of the nut-wrench jaw.
Figure 5 is a detail view of the pipe-wrench jaw.
Corresponding parts in the drawings are designated by the same letters of
reference.
Referring to the drawings:-
A represents the tool-stock, consisting of the handle B and the fixed jaw C.
The handle B has a metallic head b, with the slot ', in which turns the ratchet-
wheel c.
This ratchet-wheel is on a post journalled in the end of the handle and
having a square upwardly-extended end e, fitting a square opening in the flange of
the fixed jaw C. Integral with the post are the ratchet-wheel c, disc c', and the
threaded end or stud c³, on which screws the cap-nut a. Through the handle-
head, and on each side of handle, project into slot 6' the detents D D, which are
held to the ratchet-wheel c by the springs d d. When the detents are pulled back
with the fingers from the outside, the fixed jaw C may be placed in any desired
position with respect to the handle.
In the jaw C is a rectangular hole, through which slides the shank K of the
movable jaw C', the threaded shank being moved by the circular thumb-nut E,
which rotates on the shank K in the groove in the jaw C. The shank K is only
threaded on the top and bottom sides, while both the other sides are grooved at k.
The movable cutting-jaw C² and the backing-plate C³ therefor are provided with
open slots at the bottom, and the sides of these slots are provided with the side
studs, which work in the grooves k in the movable jaw shank. The spring C
presses the plate C3 against the jaw C. Each of the movable jaws C¹ C² has a
cutter, concaved to give a suitable bearing on the tube and notched at the middle
to take a good bite on the metal.
The movable jaws CC, backing-plate C3 and spring C₁ may be quickly
removed and a pipe-wrench or nut-wrench jaw For G substituted. Thus it will be
seen that the plumber will need but one tool-stock (which is necessarily a heavy
article) with its attachments for three purposes, thus rendering it unnecessary to
carry about with him two out of three of the ordinary stocks.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In a tool-stock of the kind described the handle B, having the head slotted
at and carrying the spring-pawls D D, the sliding jaw C', and the right-angled

page_text: fixed jaw C, having a square opening in a flange thereof, in combination with a
post having the ratchet-wheel c, the disc c', the threaded end c³, the cap-nut and
the square upwardly-extended end c to fit the square opening in the flange of the
jaw C, all constructed and arranged substantially as shown and described.
2. In a pipe-cutter, the combination, with a fixed jaw C, having rectangular
hole, of the cutter-jaw C', having a shank K in said hole threaded on the top and
bottom sides and grooved on the other two sides as at k k, the cutter-jaw C² and
plate C³, open-slotted at the bottom and provided with the side studs kk, and the
spring C, the plate C3 being arranged behind the jaw C2, and the spring C behind
the plate C³, substantially as and for the purpose described.
