Improvements in the Manufacture of Certain Articles of Sheet
Metal Hollow-ware.
We, WILLIAM HENRY WOOD Junior, of the Firm of W. Raulle & Co., of
117, Granville Street, in the City of Birmingham, Wrought Iron Hollow-ware
Manufacturer, and WILLIAM THOMAS SCRIVENS, of 94, Branston Street, in the
City of Birmingham, aforesaid, Iron Plate Worker, do hereby declare the nature
of this invention to be as follows:-
This invention has reference to sheet metal tea kettles, and the lids or covers of
the same and to other like sheet metal lids or covers such as those of saucepans,
stew pans, coffee pots, slop pails and the like.
The sheet metal neck of a tea kettle as heretofore made has a slight beading
formed round the lid hole and the edge of the metal is turned down slightly so as
to strengthen the neck. This forms a raw edge round the hole which is objection-
able. According to one part of this invention we very considerably improve the
appearance of the said necks and strengthen the same by making them in the
following manner.
We make the lid hole in the neck without the said beading, and we make the
latter separately from the neck by raising a circular or oval sheet metal blank in
dies and piercing out the central portion so as to form a round or oval trough
section ring which we then place in position round and within the lid hole on the
neck so as to stand up above the top of the neck and we fold the inner part of the
said ring backwardly spreading it out against the underside of the neck by dies or
other suitable means so that the raw edge of the lid hole in the neck is enclosed
within the ring which latter thus forms a bold beading round the lid hole making
the neck stronger then heretofore and doing away with the said raw edge. This
method of making the said necks enables us to ensure the lid holes in all the necks
which are nominally of the same size being uniform, which is very necessary when
the lids or covers are made in accordance with the second part of this invention as
if the lid holes are not uniform in size and shape the lids will not fit properly.
According to the second part of this invention we make the said lids or covers as
follows. Instead of making the ring like rim from a strip of sheet metal as is now
usually done, or raising the rim from a sheet metal blank in a piece with the lid as
is also well known, we raise the rim from a sheet metal blank separate from the top
part of the lid by means of suitable round or oval dies in a stamp or press raising
up the blank all round to the shape and size of the required rim and forming a
flange round the top of the rim which by suitable dies or other means is partly
clipped off so as to stand out for a certain distance all round the rim. The edge of
this flange is turned upwardly forming a rebate in which the top part of the lid will
fit, the top part of the lid being made with a slight projecting fange all round. The
bottom of the partly formed rim is then pierced out so as to leave the bottom edge
of the rim turned in and leaving the round or oval rim ready for fixing to the lid
which is done by placing the top part of the lid in position in the rebated upper,
part of the rim and then closing the flange of the rim down all round on to the
flange of the top part of the lid thus securing the rim and top part of the lid

part of the lid and its rim are made in this way and finished they have the same

page_text: appearance as if the rim were raised in a piece with the lid, and there is no joint
or seam in the rim as there is when the latter is made from a strip.
According to another method of carrying out the second part of this invention
we make the rim as above described but instead of its having a related flange for
the flange of the top part of the lid to fit in, we make the rim with a plain flange
which is not rebated and we make the rebated flange on the top part of the lid, as
is now usually done, and we close this flange over the flange of the rim to secure
the top part of the lid and the rim together.

Improvements in the Manufacture of Certain Articles of Sheet
Metal Hollow-ware.
We, WILLIAM HENRY WOOD Junior, of the Firm of W. Randle & Co., of
117, Granville Street, in the City of Birmingham, Wrought Iron Hollow-ware
Manufacturer, and WILLIAM THOMAS SORIVENS, of 94, Branston Street, in the
City of Birmingham, aforesaid, Iron Plate Worker, 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 consists of the heroin described improvements in the manufacture
of certain articles of sheet metal hollow-ware such as tea kettles and their lids
or covers, the tops or covers of watering cans and boiler fillers and the lids or
covers of saucepans stew pans coffee pots slop pails and the like.
The sheet metal neck of a tea kettle as heretofore made has a slight beading
formed round the lid hole and the edge of the metal is turned down slightly so as
to strengthen the neck. This forms a raw edge round the whole which is
objectionable. According to one part of this invention we very considerably
improve the appearance of the said necks and strengthen the same by making
them in the following manner which we will describe by referring to Figs. 1, 2, 3,
4 and 5 of the accompanying drawings on which Fig. 1 is a part sectional elevation
of a tea kettle shewing the neck formed in accordance with this part of our invention
and Figs. 2, 3, 4 and 5 shew various stages in the manufacture of said neck.
We make the lid hole in the neck A without the usual beading round the hole
and we make the bending separately from the neck by raising in dies a pierced
circular or oval sheet metal ring like blank which blank is somewhat larger than
is the hole in the neck and when so raised will have the shape in cross section
shewn by Fig. 4 of which Fig. 3 is an elevation and Fig. 2 is a plan. It will be scen
that this is an oval inverted trough section ring the inner edge of which
projects down somewhat further than does the outer edge . This rim is then
placed in position round and within the lid hole in the neck A as shewn in Fig. 5
so as to stand up above the top of the neck on which the outer edge b' of "the
ring&will then bear. The inner part 3 of the ring is then spread outwardly by
means of dies or other suitable tools so as to bear against the underside of the
neck A and thus the raw edge a' of the lid hole in the neck A will as shewn in
Fig. be enclosed within the ring B which latter thus forms a bold beading round
the lid hole making the neck stronger than heretofore and doing away with the raw
edge a. This method of making the necks enables us to ensure the lid holes in all
the necks, which are nominally of the same size, being uniform, which is very
necessary when the lids or covers are made in accordance with the second part of

page_text: this invention, as if the lid holes are not uniform in size anl shape the lids will
not fit properly. This method of strengthening the lid holes in the necks of tea
kettles by the trough section ring B closed within and around the same as above
described with reference to Figs. 1, 2, 3, 4 and 5, is similarly applicable, as shewa
in Figs. 6 and 7, to the covers or tops of sheet metal watering cans or boiler fillers.
Fig. 6 shewa the boiler filler in plan and Fig. 7 shews the boiler filler in pact
sectional elevation, the said trough section ring & being for.ned and fixed in aud
around the hole in the top or cover A of the boiler filler in the same way as above
described with reference to Figs. 1, 2, 3, 4 and 5.
According to the second part of this invention we make the said lids or covers
as we will now describe by referring to Figs. 8 to 14 both inclusive which illustrate
this part of our invention applied to a tea kettle lid and in which the same letters
of reference indicate the same parts in all the figures. Fig. 8 is a sectional elevation
of a tea kettle lid formed in accordance with this part of our invention and Figs. 9,
10 and 11 illustrate in cross section various stages in the manufacture of the lid
shown by Fig. 8; Fig. 12 is a sectional elevation of a slightly modified form of
the tea kettle lid shewn by Fig. 8, and Figs. 13 and 14, illustrate two stages in
the manufacture of the lid shewn by Fig. 12.
We will first refer to Figs. 8 to 11 both inclusive:-Instead of making the ring
link rim of the lid from a strip of sheet metal as is now usually done, or raising the
rim from a sheet metal blank in a piece with the lid as is also well known, we raise
the rim C from a sheet metal blank separate from the top part D of the lid by
means of suitable round or oval dies in a stamp or press, raising up the blank to
the shape and size of the required rin C as shewn in Fig. 9, that is to say, the
blank will now have the form of a shallow round or oval dish of which the upwardly
projecting sides C will correspond in shape and size with the rim C in Fig. 8, and
there is a flange c' which stands out for a certain distance all round the top of the
rim C. The edge part c' of this flange c' is in the next process turned upwardly
all round as shewn in Fig. 10 forming a rebate in which the top part D of the
lid will fit, this top part D being made with a slight projecting flange d' all round.
The bottom of the partly forined rim C is then pierced out so as to leave the
hottom edge of the rim C turned in and making a round or oval rim C as shewn
in Fig. 10 ready for fixing to the upper part D of the lid which is done by placing
the top part D of the lid in position in the rebated upper part e of the rim C aud
then closing the flange c² of the rim down all round on to the flange d¹ of the top
part D as shewn in Fig. 8, thus securing the rim C and the top part D of the lid
together and making the combined flange of the three thicknesses of metal e' d' c².
When the top part D of the lid and its rim are made and secured together in this
way and finished they have the same appearance as if the rim C were raised in a
piece with the upper part D of the lid and there is no vertical joint or seam in the
rim C as there is when the latter is made from a strip.
According to another method of carrying out the second part of this invention
illustrated by Figs. 12, 13 and 14 we make the rim C as above described but
instead of its having a rebated flange e e e for the flange d' of the top part D of
the lid to fit in, we make the rim C with a plain flange c' as shewn in Fig. 14 which
is not rebated, and we make a rebated flange d' d2 on the top part of the lid D as
shew in Fig. 13 as is now usually done and we close the part d of this flange over
the flange of the rim C as shewn in Fig. 12 thus securing the top part D of the
lid and the rim C together.
We make the rims of the lids of saucepans stew pans coffee pots slop pails and
the like and fix the said rims to the upper part of the lids in the manner above
described with reference to tea kettle lids.
Having now particularly described and ascertained the nature of our said
invention, and what manner the same is to be performed, we declare that what
we claim is:-
1. Strengthening and finishing the lid hole in a tea kettle neck by means of the

page_text: trough section ring raised from a sheet metal blank and applied and fixed in
1.d around said lid hole in the manner substantially as hereinbefore described with
reference to Figs. 1 to 5 of the accompanying drawings.
2. Strengthening and finishing the hole in the sheet metal top or cover of a boiler
filler or watering can by means of the trough section ring braised from a sheet
metal blank and applied and fixed in and around the said hole in the manner
substantially as hereinbefore described with reference to Figs. 1 to 7 of the
accompanying drawings.
3. Making the rim of the lid or cover of a saucepan stew pan coffee pot slop
pail or the like from a sheet metal blank which is raised into a shallow dish shape
with the bottom ent out and the top fange raised and rebated, and fixing the
rim thus formed to the upper part of the lid or cover by closing down the rebated
edge of the rim over the flange of the upper part of the lid, substantially as
herein before described and illustrated by Figs. 8 to 11 of the accompanying
drawings.
4. In a lid or cover of a saucepan stew pan coffee pot slop pail or the like the
combination of the upper part 1) and the jointless rim C constructed and fixed
together in the manner substantially as hereinbefore described and illustrated by
Figs. 8 to 11 of the accompanying drawings.
5. In a lid or cover of a sauce pan, stew pan coffee pot slop pail or the like the
combination, with the upper part D, of the jointless rim C, raised from a sheet
metal blauk and fixed to the upper part D in the manner substantially as
hereinbefore described and illustrated by Figs. 12 13 and 14 of the accompanying
drawings.
