Improvements in the Manufacture of Saucepans, Hanging Pots;
Stew Pots, and the like.
I, ERNEST STEVENS, of Stour Works, Cradley Heath Staffordshire, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the manufacture of saucepans, hanging
pots, stew pots and the like articles having what is known as a doubled bellied body
that is the body at about midway in its depth is greatest, and narrows about equally
as it approaches the top or the bottom. Also part of my invention relates to the
handles of such saucepans.
My invention refers primarily to the process or means employed for producing the
upper part of the bulged shape of the body; also the formation of the beading or
finishing of the upper edge of the said body; also for the attachment of the handle
tube to the connecting socket; also for the providing for and attachment of a cap to
the outer end of the said handle.
Broadly in carrying out my invention in the manufacture of a saucepan I should
proceed as follows:-
I cut out a blank of suitable diameter which is further submitted to dishing or
cupping tools which draw it to the required depth and also shapes the lower part of
the bellied configuration of the body the upper part being almost parallel. The upper
edge of this body is now trimmed truly after the ordinary manner. I now provide
a top and bottom tool which shall receive the body in an inverted position. At this
stage for some time the difficulty presented itself of placing the body in a perfectly
upright position in the bottom die before the falling pressure of the top tool. Unless
this perfectly upright position is obtained bad work must inevitably result. To ensure
this however I forin the bottom die of such a size as to receive just freely the inverted
body; and at a given depth I provide a narrow ledge upon which the edge of the
body rests, just sufficient for the operator to feel it resting there, and thus ensure
without further test, the perfectly upright position of the article. The lower part of
the die is further shaped so as to partly form the contracted shape of the upper part
of the body. By the downward pressure of the top tool the edge of the body is
pushed past (or over) the narrow ledge-which offers but little resistance--and forced
into the lower part of the die. The body is further submitted to similar tools except that
no narrow ledge is now necessary, and thus the upper part is narrowed and shaped to
the figure required.
I now proceed to treat the upper or mouth edge of the body, in order to produce
a bead like termination. Cylindrical edges of metallic bodies are usually formed into
a bead by means of a roller or rollers being pressed against the interior of the
said edge &c.
In this my invention however provide a chuck plate having upon its face a
narrow edge or set off, of about a diameter equal to the interior of the body mouth,
and upon which the latter is passed. A rotary motion is permitted to the body and
the chuck plate. I now bring up a mounted roller to act upon the exterior of the
CD17

page_text: .
body at a position just outside the line of the narrow ledge upon the chuck, so that
as the roller is forced inwards, the outer edge is forced outwards almost to a right
angle with the side of the body. The body is now subjected to the ordinary treatment
of beading roller to perfectly turn over the edge and complete the beading.
In forming the handles for saucepans I make a socket having at its base a plate
by which it may be rivetted &c. to the body. This socket has a round hole to receive
the tubular handle, but this round hole developes into a square shaped termination
at the outer face of the base plate. I form the tubular handle by means of a flat
blank cut to the required shape and bent and rounded in the usual manner. The one
(small) end of this is so shaped that when it is passed into the socket, there shall be
four points which shall stand somewhat forward and which by suitable tools shall be
then pressed down into the corners of the square hole in the socket. By these means
the handle is firmly fixed in the socket and any liability to its becoming loose or
turning round or withdrawal is entirely prevented.
At the outer end of the handle I now provide and fix a wrought metal cap as
follows: I cut out and shape in a shallow cup form a cap of suitable diameter and
depth. I then subject the tubular end of the handle to similar treatment as I did the
initial stage to form the beading upon the edge of the body, that is, I provide a chuck
plate having a narrow ledge to fit the interior of the handle and bring to bear upon
the external a pressure roller by which an outwardly raised small flange is made. I
then place over this flange the cap as previously prepared and then roll the edge of
the said cap over the flange by which the cap is rigidly secured and thus presents a
neatly finished appearance thereto. The cap may or may not be perforated
according to fancy.

Improvements in the Manufacture of Saucepans, Hanging Pots,
Stew Pots, and the like.
I, ERNEST STEVENS, of Stour Works, Cradley Heath, Staffordshire, 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 improvements in the manufacture of saucepans, hanging a
pots, stew pots and the like articles having what is known as a double bellied body,
that, is, the body at about midway in its depth is greatest in diameter, and narrows
about equally as it approaches the top or the bottom. Also part of my invention
relates to the handles of such saucepans.
My invention refers primarily to the process or means employed for producing the 4
upper part of the bulged shape of the body; also the formation of the beading or
finishing of the upper edge of the said body; also for the attachment of the handle
tube to the connecting socket; also for the providing for and attachment of a cap to
the outer end of the said handle.
In order to more clearly explain this my invention I have appended hereunto
illustrative drawings upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part.

Fig. 20, shows the said cap in its fixed position,
Broadly in carrying out my invention in the manufacture of a saucepan I should
proceed as follows:-
I cut out a blank of suitable diameter which is further submitted to dishing or
cupping tools which draw it as shown in Figs. 2 and 3, to the required depth, and also
shapes the lower part 22 of the bellied configuration of the body 23, the upper part 24
being almost parallel. The upper edge 25 of this body is now trimmed truly
after the ordinary manner. Thus far the operations and means are of the usual kind
and are merely referred to for the sake of description of the whole. I now provide a
top tool 26, and bottom tool 27 see Fig. 4, which shall receive the body 23 in an
inverted position. At this stage for some time the difficulty presented itself to me
of placing the body in a perfectly upright position in the bottom die 27 before the
falling pressure of the top tool 26. Unless this perfectly upright position is obtained a
certain percentage of bad work will be produced. To positively ensure this upright
position however I form the bottom die of such a diameter as to receive just freely the
inverted body 23, and at a given depth I provide a narrow ledge 28 upon which the
edge 25 of the body rests, just sufficient for the operator to feel it resting there, and
thus ensure without further test-the perfectly upright position of the article. The
lower part of the die 27 is further shaped so as to partly form the contracted shape of
the upper part of the body. By the downward pressure now of the top tool 26 the
edge 25 of the body is pushed past (or over) the narrow ledge 28-which offers but
little resistance and is forced into the lower part of the die, by which it is partly
shaped as desired. The body 28 is further submitted to similar tools except that
in the bottom die no narrow ledge 28 is now necessary, such as shown in Fig. 5,
and thus the upper part of the body is narrowed and shaped to the figure
required.
I now proceed to treat the upper or mouth edge of the body, in order to produce
the bead like termination as seen at 29 in Figs. I and 9. Cylindrical edges of metallic
bodies are now usually formed into a bead by means of a roller or rollers being pressed
against the interior of the said edge &c.
In this my invention however I provide a chuck plate 30, see Fig. 7, having upon
its face a narrow edge or set off 31, of about a diameter equal to the interior of the
body mouth, and upon which the latter is passed. A back pressure piece 32 is brought
to bear against the body 23 so as to keep it up to its work. A rotary motion is now
given to the body 23 and the chuck plate 30. I now bring up a mounted roller 33
which is forced upon the exterior of the body at a position just outside the line of the
narrow ledge 31 upon the chuck plate 30, so that as the roller is forced inwards, the
•

page_text: :
outer edge 25 is forced outwards almost to a right angle with the side of the body as
shown. The body is now subjected to the ordinary treatment of beading rollers
to perfectly turn over the edge and complete the beading as shown in Figs. 8
and 9.
In these two views it will be noticed that having placed the body 23 (as produced
in Fig. 7) upon the chuck 34, see Fig. 8; and brought up to it the support 32 as
before, the ordinary roller 35 is pushed against the edge in the direction of the
arrow 36 until it is partly beaded as shown. This process is repeated as shown in
Fig. 9, with the exception of the roller 35 being pushed upon the already partly
formed bead in the direction of the arrow 37, and thus the bead is completed.
These two last operations I am aware are not new but are only here inserted for
continuity of description of manufacture.
Referring to Figs 10 to 20-In forming the handles I make a socket 38 having
at its base a plate 39 by which it may be rivetted &c. to the body of the saucepan.
This socket has a round hole 40 to receive the tubular handle but this round hole
developes into a square shaped termination as seen at 41, Figs. 10 and 11, at the outer
face of the base plate. I form the tubular handle 42 by means of a flat blank 42°
see Fig. 12, cut to the required shape which is then bent and rounded in the usual
manner, as seen in Fig. 13. The one (small) end of this is so shaped that when it is
passed into the socket 38 there shall be four points indicated by dotted lines 43, 44, 45
and 46 see Fig. 12, which shall stand somewhat forward from the intersecting
angular lines 47, 48, 49 and 50 in the square termination 41. The metal is then slit
at the said dotted lines; and the overhanging portions then flattened or rivetted down
on to the socket or in some cases the metal may by suitable tools be then pressed
down into the corners of the square hole in the socket. If preferred the slits at the
dotted lines Fig. 12 may be made while the blank is in its flat state. By these means
the handle is firmly fixed in the socket and any liability to its becoming loose or
turning round or being drawn out is entirely prevented.
At the outer end of the handle I now provide and fix a wrought metal cap 51 as
shown in Fig. 20. I cut out and shape in a shallow cup form the partly made cap 52
as seen in Figs. 17 and 18, of suitable diameter and depth. I then subject the tubular
end of the handle to similar treatment as before described and illustrated in reference
to Fig. 7, to form the beading upon the edge of the body 23, that is, I provide a chuck
plate having a narrow ledge similar to 31 to fit the interior of the handle, and then
bring to bear upon the external of the said handle a pressure roller similar to 33, by
which an outwardly raised small flange 53 is made similar to the flange shown in
Fig. 7. I then place over this flange the cap as previously prepared as seen in Fig. 19,
and then roll or close the onter edge of the said cap over the flange 53 by which the
cap is rigidly secured and thus presents a neatly finished appearance thereto, as seen
in Fig. 20 The cap may or may not be perforated at 54 according to fancy.
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 :-
1. In the manufacture of saucepans, hanging pots, stew pots, and the like articles,
the bellying or first operation of bellying of the upper part of the body of such
articles, by means of the combination of a suitable top tool 26, with a bottom tool 27
