We WILLIAM TOPHAM and EDWARD SNUSHALL both of N° 26 Oxford Street
Birmingham in the County of Warwick Iron Plate Workers and Galvanizers do
hereby declare the nature of the said Invention for IMPROVEMENTS IN THE
MANUFACTURE OF CERTAIN PARTS OF TEA KETTLES AND OTHER VESSELS to be
as follows:
"
Our invention has reference to the formation of a raised bead around the
openings or mouths of tea kettles and other vessels in which openings the lids
or covers fit and also to the wiring of the edge of the said openings.
The wiring of the openings or mouths of tea kettles and other vessels is ordinarily
effected by hand labour.
According to our invention we produce a raised bead around the opening or
mouth by stamping and effect the wiring by a press as hereinafter described.
By our invention economy in the beading and wiring of the openings or mouths
of tea kettles and other vessels is effected and the openings so made and wired
have a neatness and uniformity in figure and size unattainable in hand wired
openings. Owing to the uniformity in the figure and size of the openings formed
by our invention lids made in the ordinary way will fit the said openings without
the necessity for the special fitting of the lids requisite in hand wired openings.
We will describe our invention as applied to a tea kettle made of sheet iron or
partly of copper or brass and sheet iron but our invention may be applied to tea
kettles made of copper brass or other sheet metal.
We cut from sheet iron by means of shears a blank of the required size to form
the top or neck of the tea kettle and in the middle of the blank we make by a
press and press tools a hole or opening By a stamping process the flat blank is
domed or cupped and at the same time and by the use of the same pair of dies the
opening in the blank is turned inwards so as to form a rim and around the said
turned in edge or rim a groove semi circular in cross section is made for receiving
the ring of wire for wiring the edge of the opening. After the ring of wire has
been placed in the groove the top or neck of the tea kettle is subjected to a

page_text: pressing operation whereby the edge of the raised rim is closed over the wire so as
to fix it in the groove and at the same time round the edge of the opening. The
wiring of the edge of the opening in the top or neck of the tea kettle is thereby
completed the groove in which the wire is fixed forming in the finished top or neck
a raised external bead around the opening. Our invention may be applied to tea
kettles oval or circular in horizontal section and to the openings of metallic
chamber or slop pails and to the cover holes or openings of other vessels.

We WILLIAM TOPHAM and EDWARD SNUSHALL both of N° 26 Oxford Street,
Birmingham, in the County of Warwick, Iron Plate Workers and Galvanizers, do
hereby declare the nature of our Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF CERTAIN PARTS OF TEA KETTLES AND OTHER VESSELS and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
"
Our invention has reference to the formation of a raised bead around the
openings or mouths of tea kettles and other vessels, in which openings the lids or
covers fit, and also to the wiring of the edge of the said openings.
The wiring of the openings or mouths of tea kettles and other vessels is
ordinarily effected by hand labour or by spinning.
According to our invention we produce a raised bead around the opening or
mouth by stamping and effect the wiring by a press as hereinafter described.
By our invention economy in the beading and wiring of the openings or mouths
of tea kettles and other vessels is effected and the openings so made and wired have
a neatness, strength and uniformity in figure and size unattainable in hand wired
openings. Owing to the uniformity in the figure and size of the openings formed
by our invention, lids will fit the said openings without the necessity for the special
fitting of the lids requisite in hand wired openings.
We will describe our invention as applied to a tea kettle made of sheet iron or
partly of copper or brass and sheet iron, but our invention may be applied to tea
kettles made of copper, brass or other sheet metal.
We cut from sheet iron by means of shears, a blank of the required size to form
the top or neck of the tea kettle and in the middle of the blank we make by a
¨press and press tools a hole or opening. By a stamping process the flat blank is

page_text: domed or cupped and at the same time and by the use of the same pair of dies the
opening in the blank is turned inwards so as to form a rim and around the said
turned in edge or rim, a groove semi circular in cross section is made for receiving
the ring of wire for wiring the edge of the opening. After the ring of wire has
been placed in the groove the top or neck of the tea kettle is subjected to a pressing
operation whereby the edge of the raised rim is closed over the wire so as to fix it
in the groove and at the same time round the edge of the opening. The wiring of
the edge of the opening in the top or neck of the tea kettle is thereby completed,
the groove in which the wire is fixed forming in the finished top or neck a raised
external bead around the opening. Figure 1 of the accompanying Drawings
represents in elevation partly in section an elliptical tea kettle, drawn to a small
scale, the raised beading around the mouth or opening of the tea kettle and the
wiring and rounding of the edge of the said mouth or opening being effected by
stamping and pressing according to our invention; a is the body of the tea kettle
made of sheet iron and 6 the top or neck of the kettle made of copper or brass or
of the same metal or alloy as the body a: c is the lid or cover; d is the raised
hollow bead around the mouth or opening in the top or neck of the kettle and e is
the wire situated in and fixed to the said bead d.
In producing the said hollow bead d and wiring the said bead and rounding the
edge of the opening or mouth in the top or neck of the tea kettle we proceed in
the following manner,
The Figures hereinafter described with reference to which we shall describe the
manner of carrying our invention into effect are drawn to the same scale as the tea
kettle Figure 1.
We take a flat blank of sheet metal having the shape represented in Figure 2
but we do not limit ourselves to the use of any particular shaped blank. We prefer
to cut out the blank from sheet metal by shears. By means of a series of stamping
operations effected by dies and appliances of the ordinary kind the blank Figure 2
is brought into the form represented in plan of upper side in Figure 3 and section
in Figure 4; that is to say, the blank is domed or cupped at b and the metal at
the middle of the blank is pressed inwards so as to form a depression of the top of
the rim g of the said depression where it joins the dome part 6 having a groove
or hollow bead d semi-circular in cross section. The bottom of the depression fin
the domed blank is next pierced out as represented in plan of underside in.
Figure 5 and section in Figure 6. The opening in the beaded and domed top
of the kettle is now ready for the wiring and rounding operation To effect this,
the partly made top or neck of the tea kettle Figures 5 and 6 is placed in the
lower or fixed die of a press with its convex face downwards and the ring of
wire e represented in Figure 7 is placed in the groove or beading d and by the
descent of the upper or moveable die of the press the edge of the rim g is closed
over or nearly over the wire ring e in the beading or groove d so as to fix it in the
said beading or groove and at the same time round the edge of the opening has
represented in plan of underside in Figure 8 and section in Figure 9. The wiring
and rounding of the opening in the top or neck of the tea kettle is now complete,
the groove in which the wire ring is fixed forming in the finished top or neck a
raised external bead d around the opening in the said top or neck. By clipping
or otherwise cutting away the superfluous sheet metal at the edge of the dome
part 6 of the top or neck, it is finished as illustrated in plan of upperside in
Figure 10 and side elevation in Figure 11 and is ready to be joined to the body a
(Figure 1) which body may either be made of the same metal or alloy as the top
or neck or of a different metal or alloy.
Our invention may be applied to tea kettles oval or circular in horizontal section
and to the openings of tea and coffee pots, metallic chamber or slop pails and water
cans and to the cover holes or openings of other vessels.
In applying our invention to the articles enumerated and to other articles, we
proceed substantially as herein before described and illustrated with respect to a
lea kettle.

page_text: Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that
we claim as our invention of "Improvements in the manufacture of certain parts
of tea kettles and other vessels
"
Making a raised hollow bead and an internal rim around the cover holes openings
or mouths of tea kettles and other vessels by stamping and piercing and afterwards
wiring and rounding the edge of the said cover holes or openings by closing the
edge of the raised internal rim by a pressing operation over a wire ring placed in
the hollow bead substantially as hereinbefore described and illustrated in the
accompanying Drawings.
