PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Baths, Troughs, Tanks, and
similar Vessels.
I, SAMSON Fox, of Leeds Forge, New Wortley, Leeds, in the County of York,
Engineer & Ironmaster, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the manufacture of vessels having a considerable
depth such as baths or troughs, and tanks for galvanizing and other purposes.
Such vessels in consequence of their depth have heretofore been made either in
one piece by casting, or in several pieces secured together as for example by
rivetting.
Now this invention has for object to enable such vessels to be produced in one
piece in a simple cheap and rapid manner from metal plate such as iron or steel.
For this purpose I subject a plate of iron or steel of suitable shape and thickness
to one or more stamping or pressing operations between dies the forms of which are
made to correspond to the shape of the vessel to be produced, or to the shape of
the vessel at the various stages of its manufacture.
Dated this 11th day of September 1891.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Baths, Troughs, Tanks, and
similar Vessels.
I, SAMSON Fox, of Leeds Forge, New Wortley, Leeds, in the County of York,
Engineer & Ironniaster, 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:-
Vessels of considerable depth, such as baths, troughs, and tanks for galvanizing
and other purposes, have heretofore been made either in one piece by casting or in
several pieces secured together for example by rivetting.
Now this invention has for object to enable such vessels to be produced in one
piece in a simple cheap and rapid manner from metal plate such as iron or steel.
For this purpose iron or steel is rolled to the desired thickness; is cut to suitable
shape and afterwards is subjected to one or more stamping or pressing operations
between dies the forms of which are made to correspond to the shape of the vessel
to be produced, or to the shape of the vessel at the various stages of its manufacture,
as I will now explain with reference to the accompanying sheet of illustrative
drawings whereof
Fig. 1 shows in longitudinal vertical section a set of dies adapted to perform the
first stamping, or pressing operation on a metal plate intended to be converted into
a bath trough or tank suitable for galvanizing purposes, such a metal plate being
shown between the dies pressed to the shape they are designed to impart after the
first operation.
Fig. 2 is a cross section of the same.
Fig. 3 shows in longitudinal vertical section a second set of dies designed to
perform the second or final stamping operation on the plate that has previously

page_text: been operated upon by the dies represented in Figs. 1 and 2. Between the dies in
Figs. 3 and 4 the completely shaped bath trough or tank is shown.
Fig. 4 is a cross section corresponding to Fig. 3.
Fig. 5 is a plan of the completed bath trough or tank.
Fig. 6 shows the shape to which the plate is cut preparatory to being subjected
to the action of the dies represented in Figs. 1 and 2. a is a male die, it is secured
to the top table. of a hydraulic or other press. is a female die or matrix; it is
-secured to the bottom table of the press.
In carrying out my invention, I take a piece of plate (preferably mild steel) and
after cutting it to the required size and shape (see Fig. 6) I heat it, then I place it
upon the female die or matrix b.
The dies a and b are then caused to approach each other, (or one is caused to
approach the other) and the plate is pressed between them until it assumes the
shape shewn in Figs. 1 and 2.
c is a second male die, and d a corresponding female die or matrix, the shapes of
these being such as to impart the required finished form to the plate, which, after
being operated upon as described by the dies represented in Figs. 1 and 2, is
removed and if necessary re-heated; then it is placed upon the female die d which
is caused to approach the male die c, thereby bringing the plate to the required
finished shape of a bath trough or tank as shown in Fig. 3, 4 and 5.
The dies a, b, c, d are respectively made in two or more sections fastened together
e, or in some cases it may be found advantageous to make each die in one
by bolts
piece.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
.claim is :-
The hereinabove described improved manufacture of vessels of considerable depth
such as baths, troughs tanks, and similar vessels in one piece, cutting to shape,
heating and pressing a sheet of metal by means of dies such as a b c d to the required
form as set forth and explained with reference to and illustrated in the accompanying
.drawings.
