1 JOHN STEVENS of Quarry Bank Brierley Hill in the county of Stafford
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of kettles, and consists of the improvements
hereinafter described in the construction of their component parts, and their putting
together, which improvements are applicable to such articles made of any suitable
metal.
By my invention the manufacture of such articles is very much simplified and
economized, and an article is produced which is very much superior for its uses, than
those at present in use.
In the ordinary method of constructing these articles the "body" is made of two or
more pieces; sometimes the said body is built up partly of a lower or bottom part, and
partly of an upper part, which said upper part may be attached to, or in some instances
form part of, the neck and breast of the kettle. The joint or seam thus formed
connecting the two parts composing the body, necessarily are exposed to the action of
the flames of the fire, which is objectionable. In this my invention however I make
the body of the kettle, of one piece stamped and pressed into form, and then
connect the breast and neck thereto. I take a blank and by suitable tools in what are
usually termed American drawing through presses, or similar machines, by successive
operations form the body of the kettle.
The finishing operations or forming it into the swelled or curved form, I prefer
generally to perform by means of the drop stamp. The upper or breast part of the
kettle is then made, and the joints, of the breast, and body are lapped over each other
and rolled into a bead form, and firmly secured together.
Thus the seam or joint is removed farther away from the action of the flames, and
the liability to leakage prevented, while the article is stronger and more cheaply
produced.

Manufacturer 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:-
This invention relates to certain improvements in the manufacture of sheet iron or
sheet steel kettles, and consists of the stamping or drawing of the bodies of such
articles out of one piece of metal, and of forming the joints of such bodies with the
other parts of the kettles, each and all after the manner following.
By my invention the manufacture of such articles is very much simplified and
economized, and an article is provided which is very much superior for its uses than
those of present make.
In the ordinary method of making these iron or steel kettles, the body is mado of
two or more pieces; sometimes the said body is built up partly of a lower or bottom
part, and partly of an upper part, which said upper part may he attached to, or in
some instances form part of the neck and breast of the kettle. The joint or scam thus
formed connecting the two parts composing the body, necessarily are exposed to the
action of the flames of the fire which is objectionable. In this my invention however,
I make the body of the kettle of one piece stamped and pressed into form, and then
connect the neck thereto.
I take a blank and by suitable tools in what are usually termed American drawing
through presses or similar machines by one or more operations, form the body of tho
kettle.
The finishing operation of forming it into the swelled or curved form, I prefer
generally to perform by means of the drop stamp. The upper or neck part of the kettle
is then made and the joints of the neck and body are lapped over each other and rolled
into a bead form, and thus firmly secured together.
Thus the scam joint is removed farther away from the action of the flames and the
liability to leakage prevented, while the article is stronger and more cheaply made.
I will now more particularly describe this my invention, and the manner in which
it is to be performed by the aid of the accompanying illustrative sheet of drawings,
upon which are figures and letters of reference.
Fig. 1, is a blank of sheet iron or steel from which the body of the kettle is to be
made.
Fig. 2, is the neck of the kettle, made from a similar blank to that of Fig. 1, but
the stamping of such necks from sheet iron or steel is not new, and forms no part of
my invention, but illustrated for the purpose of explanation, in reference to the joint,
which secures it to the body b, and to show the complete construction of the kettle.
Fig. 3, is a sectional view of the body of the kettle.
Fig. 4, is a sectional view of the kettle spout.
Fig. 5, is an enlarged detailed section of the joint of the body and neck of the
kettle.
Fig. 6, is an enlarged detailed section of joint connecting the spout to the body
of the kettle.
Fig. 7 shows a view of kettle made after the manner of this my invention.
I take the blank a, Fig. 1, and by suitable tools in a drawing press, now generally
known as an American drawing press, having a pressure plate firmly holding the edges

page_text: of the inetal, while the force (top tool) descends and forces the metal into the bottom
tool or die.
Generally I should accomplish this at one operation of a sufficient depth and shape
from which to form the body b, but more than one such operation may be used if
necessary.
I find it preferable to so form the tools in the drawing press, as that the sides of the
articles produced therefrom shall be straight or nearly so, see dotted lines in Fig. 3.
and then pass it through one operation in an ordinary drop stamp having suitable tools
to give it the necessary or desired curved or swelled form at c. The edges of the
metal are trimmined at d, thus forming a narrow flange around the top as seen in
Figs. 3 & 5.
From a similar blank to that shown in Fig. 1, I stamp or press the neck e, of the
kettle, and trim or cut the edge f, as shewn in Fig. 2. The upper edge of the body of
the kettle or flange d, is then passed into the recess or flange of the neck part.
The body of the kettle being now placed in a revolving chuck or other similar
suitable tool, a "rolling" or turning over tool is brought to bear upon the flange f
which folds or rolls the said flange d & faround together into a bead form, so tight and
firm, as to be practically solid, thus requiring no solder whatever to make it watertight.
The flange fas formed upon Fig. 2, may if desired be formed upon Fig. 3, and that
shewn upon Fig. 3, be shewn upon Fig. 2, but generally I find it more convenient
and prefer to adopt the order illustrated.
At g provision is made to receive the spout h. The metal around the edges of the
perforation 9, is turned outwards.
The spout h, is formed by any of the present known methods of manufacture, having
a groove or recess formed at k.
The perforation 9, is made of sufficient size to admit the passage therethrough
from the inside, of the spout h. When the spout his thus placed in position, suitable
tools are provided to support the inside end of the said spout (see Figs. 4 & 6) when
the metal at i, is then pressed or flattened down firmly in the groove at k, which
makes a strong, neat, and tight joint.
The forming or attaching of the handle or lid m, to complete the article, are done
in the ordinary method of manufacture.
These my improvements apply equally well to oval or round kettles, the several
operations in each case being similar.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed I declare that what I.
claim is
1st. The improvements in the manufacture of kettles, hereindescribed and illustrated,
that is to say The making of the bodies of round or oval kettles, of one piece of sheet
iron or sheet steel.
2nd. The making of the bodies of round or oval kettles, of one piece of sheet iron
or sheet steel by the drawing or stamping process, substantially as,
and for the purposes
specified and illustrated.
3rd. The improvements in the manufacture of sheet iron or sheet steel kettles,
hereindescribed and illustrated, that is to say:-The forming and securing of the
joint, connecting the body to 'the neck of such articles, by the rolling over process
without soldering.
