COMPLETE SPECIFICATION.
Improvements in the Manufacture of Kettles, Sauce-pans, and other
Sheet Metal Articles.
I CHARLES HENRY HILL of the firm of Francis Hill of Belmont Works Belmont
Row Birmingham in the County of Warwick Manufacturer do hereby declare the
nature of my said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My invention has for its object, improvements in the manufacture of kettles sauce-
pans and other articles and refers in particular to the mode of uniting the various
members constituting such articles together so as to make the said article what ever it
may be as nearly approaching a formation of one piece, while at the same time
they may be made from wrought plates of any kind of metal much cheaper than
heretofore.
In order that iny invention may be clearly understood and more easily carried into
practice, I have appended hereunto, a double sized sheet of drawings upon which I
have illustrated the application of my invention to an ordinary kettle and sauce pan
as well as several enlarged modifications in the particular shape.
Figure 1. shews a sectional elevation of the side A of an article such for instance
as the kettle shewn by Figure 8 with the top B in position for being joined thereto as
afterwards described.
Figure 2. is a similar sectional elevation shewing the parts united together the
joint having in this view a round formation.
Figure 3 is a similar view to Figure 2 but with a V shaped joint instead of the
round.
Figure 4. is an enlarged elevation of the side A attached to the bottom D of the
article the joint in this case having a rounded formation.
Figure is a similar view to Figure 2 but with a V shaped joint in place of the
round.
Figures 6 & 7 are sectional elevations shewing the tops united to the sides by an
internally pressed joint of different shapes.
Figure 8 is a general view of a kettle having its top and bottom united to its side
by means of my improvement.
Figure 9. is a sauce-pan with the bottom similarly joined to the side.
I will proceed to describe my invention in connection with the uniting of the top
and side, or bottom and side of an ordinary tea kettle in which I take the side A and
top B the latter of whatever shape it may be being flanged at 6' so as to lap a certain
distance over the side A as shown at Figure 1.
I then by the use of a jennie, lathe or other suitable machine press against the
inside by means of the edge of the revolving wheel E or its equivalent, and against
the outside by means of the two revolving wheels F and F or their equivalents thus
acting upon the double metal at this point from the centre, on the inside, and from the
sides on the outside in such a manner as to press out a bulge K which may be round
as shewn finished at Figure 2 or V shaped as shewn by Figure 3 but I do not
confine myself to either of these shapes, as I may form the bulge of any shape or
angle between these two although the moderate the angle the more substantial will be
the joint.
In this manner I form a locked joint which while being thoroughly free from
leakage is at the same time so easily made that it will considerably cheapen the article
of which it forms a part.
The joining of the bottom D to the side A. is formed in an exactly similar manner
to that before described the bottom D being provided with a flange to lap over the
side A, and thereby form the double metal for the bulge K and it will readily be seen

page_text: that instead of the metal being bulged outside the one wheel E might be placed
outside the article, the two wheels F and F¹ being placed inside so that the bulge K
of the joint would instead of projecting outwards-be within the article to be united
as shewn at Figures 6 and 7.
In this manner the various portions of all curved articles may be united together in
such a manner that they become practically to all intents and purposes, one piece
while at the same time, the labour of production is much economized.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvements in the manufacture of kettles saucepans and other articles by
means of a straight edge and flanged plate pressed together so as to take the shapes
shewn by Figures 2. 34 and 5 or any modification of the same substantially as and
for the purpose herein set forth and shewn upon the drawings.
