IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION OF METALLIC BATHS to be as follows:
Year: 1884

page_text: We JAMES WATT PERKINS and RICHARD WOODHOUSE PERKINS trading as
B. Perkins and Son, Tinware manufacturers of 133, Bermondsey Street, Southwark
in the county of Surrey do hereby declare the nature of our invention for
"IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION OF METALLIC BATHS
to be as follows:-
"
This Invention relates to improvements in the manufacture and construction of
metallic baths and consists in a novel manufacture and construction of baths,
whereby we produce a bath with less labour and cost, and secure great additional
advantages.
In carrying our invention into practise we stamp the head and foot of the bath,
to the required curves and contour, vertical and horizontal, out of thin sheet steel,
copper or other suitable material, without seam, while hot, by means of a die and
plunger. By our process of stamping we leave flanges round all the edges of the
head and tail ends to which the central straight portion of the bath and the
stiffening roll at the top, are secured by the usual grooved and soldered joints;
finished so as to be quite flush and invisible inside the bath.-Hitherto the head
and foot of baths have never been stamped, but hammered and fashioned to the
required contour by manual labour, or filled in at the angles by rivotted gussets
and cement or solder; but by our process, neither filling in rivetting up, or cement
or solder is required.
The sheet steel or copper is tinned to prevent rust, and to preserve the edges of
the material By our invention the incoming hot water is not chilled by contact
with cold thick metal, which is one of the great disadvantages of cast iron or other
baths constructed of thick metals.
The baths produced by our invention are lighter, more durable and more rigid
than has been the case hitherto, and are finished by japanning or enamelling in the
usual manner.

We JAMES WATT PERKINS and RICHARD WOODHOUSE PERKINS trading as
B. Perkins and Son Tinware manufacturers of 133 Bermondsey Street Southwark
in the county of Surrey do hereby declare the nature of our invention for
"IMPROVEMENTS IN THE MANUFACTURE AND CONSTRUCTION OF METALLIC BATHS
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-.
"
This invention relates to improvements in the manufacture and construction of
metallic baths, and consists of a novel manufacture and construction of such baths
whereby we are enabled to produce them with less labour and cost, and secure
great additional advantages.
The accompanying drawings illustrate clearly our invention.-Figures 1, and 2,
are elevations of plunger and sections through die, forming the head and foot of
the bath; Figure 3, shows the bath in three parts, stamped and ready to put
together; and Figure 4 shows the completed bath with stiffening roll attached.
A is the plunger; B, the die; C, the sheet of metal in position for stamping;
D, is the foot, E, the head, and F, the central straight portion of the bath ; Ĝ, the
stiffening roll; and H the flanges.
In carrying our invention into practise we stamp the head E, and foot D, of the
'bath to the required curves and contour vertical and horizontal, and without seam,
out of sheet steel copper or other suitable material, of such thickness as is necessary
or desirable.
f
Although we are able to stamp the sheets, while cold, we find it advantageous to
do so while hot.
We use for our purpose specially shaped pressure stamps or plungers A, actuated
by suitable mechanical means, falling upon the sheet of steel copper or other
material C, of which it is desired to construct the bath, and. forcing the said sheet
into a die B, of the required shape. We leave if required flanges H, round all the
⚫ edges of the head and foot ends, to which the central straight portion of the bath F,
and the stiffening roll G, at the top, may be secured by the usual grooved and
soldered joints, finished so as to be quite flush and invisible inside the bath.
Hitherto the head and foot ends of baths have never been stamped but hammered
and fashioned to the required contour by manual labour or filled in at the angles
by rivetted gussets and cement, or solder, but by our process neither rivetting up
or cement or solder is required.
The sheet steel copper or other material is tinned to prevent rust and to preserve
the edges of the material.
The baths thus produced by our invention have the special advantages of light-
ness, durability, strength, and elasticity. They are not liable to fracture or rust,
and the incoming hot water is not chilled by contact with cold thick metal, which
is one of the great disadvantages of cast iron and other baths constructed of thick
metal,

page_text: The baths may be japanned or enamelled with perfect finish in any kind of
marble or tint of colour.
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
The stamping of the head and foot ends of metallic baths without seam, and
with or without flanges out of sheet steel copper or other suitable material, by
means of pressure stamps and dies substantially as hereinbefore described and
illustrated by the accompanying drawings.
