:-
1, HINY WILLIAM LOOSEMORE of Reliance Works, Bow, London, E. Metal
Plate Worker, do hereby declare the nature of this invention to be as follows
In the present manufacture of "bellied copper and other wrought metal
cooking utensils, the plate is bent round and joined by braizing which is rather
expensive. By my invention I can produce all kinds of bellied cooking utensils
without braizing.
This effect substantially as follows:-
I first bend the copper plate round, turn round the edges having previously
cleaned them and hook them together, and hammer them close, I then turn up the
metal round the edge of the bottom, and turn up the edge of the plate that will
form the bottom, and hook it on and hammer close; we then pickle or clean the
inside of the article and dip it into molten tin which runs into the seams and secures
them tight. Instead of dipping the article into molten tin the tin could be melted
into the seam by any known means. After the seam is secured by tin the belly is
produced by hammering the article on sand or by bulging machinery. Owing to
the ductibility and holding quality of the tin the seam can be extended in the
bellying operation without starting the seam.

Improvements in the Manufacture of Copper and other Wrought
Metal Cooking Utensils.
1, HENRY WILLIAM LOOSEMORE of Reliance Works, Bow, London E. Metal
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:-
In the present manufacture of "bellied" copper and other wrought metal cooking
utensils, the plate is bent round and joined by braizing which is rather expensive;
and in wrought iron utensils, the braizing prevents their being enamelled inside.
By my invention I am able to produce all kinds of bellied or non-bellied cooking
utensils, enamelled inside if desired, without braizing, and much cheaper than they
can now be produced.
To enable my invention to be properly understood, I will proceed to fully describe
the same with aid of the accompanying drawings.
Figure 1. being a view of a straight saucepan.
Figure 2. a cross section of same.
Figure 3. a view of a bellied saucepan.
1 carry my invention out in the following manner, I first bend the metal plate
round, turn round the edges having previously cleaned them and hook them together
as at A Figure 2. and then hammer them close, I then turn up the metal round the
edge of the bottom, and turn up the edge of the plate that will forn the bottom,
and hook it on and hammer close I then clean or pickle the inside and dip it into
molten tin which runs into the seams and secures them tight. Instead of dipping
into molten tin the tin could be melted into the joint in any known way.
After the

page_text: seam is secured by tin the "belly" is produced by hammering the article on sand
or by bulging machinery. Owing to the ductibility and holding nature of tin the
seam can be extended in the bellying operation without starting the seam, and a
joint made in this way will also admit of being enamelled in the usual way without
the seam starting.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is,
1. The manner of producing seamed wrought metal bellied cooking utensils, as
described.
2. The manner of producing seamed wrought metal cooking utensils that will
admit of inside enamelling, as described.
