page_text: I HENRY HARRIS LAKE of the firm of Haseltine Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of said invention for "IMPROVEMENTS IN THE MANUFACTURE OF PLATE OR SHEET
METAL HOLLOW-WARE to be as follows:-
"
This invention relates to that description of plate or sheet metal hollow ware
which has a beaded rim or which has the bottom or end joined to the body and it
consists in the use of male and female dies for performing the operations of making
the beaded rims and joining the bottom or end of the body.
The invention is not applicable to cast metal goods, but only to those made of
plate or sheet metals and capable of being bent into the required shape by pressure
It is especially applicable in the manufacture of such articles as tin cups and pails
and Coffee and spice tins.
According to the said invention the body of the cup or other article is placed
over the male die.
The bottom or end of the can is placed, with the flange upward, inside the upper
end of the body and pressed into position on the top of the male die, the female die
is then placed on the top of the body on the edges of which it rests.
I now apply pressure to the top of the female die which has the effect of forcing
the lower edges of the body to follow the line of the curve of the groove at the
bottom of the male die so as to form it into a curl or beaded rim and also of forcing
the top edges of the body, together with the flanges of the bottom or end; to follow
the line of the groove in the female die so as to form it into a curled joint The
female die is then lifted off the male die and the vessel removed therefrom,
completed, so far as it can be by my invention.
In the case in question the cup would be complete save and except the handle
which must be soldered on in the ordinary manner.
The formation of the longitudinal joint forms no part of this invention and may
be made in any approved way.

page_text: It will be evident that the sizes of the vessels, and their rims, and their joints
may be varied as required, and if so preferred, the female die may be fitted to act
with various sizes of male dies.
It is also evident that vessels having no beaded rim but to the bottom or end as
in coffee and spice tins, may readily be made by my invention by simply dispensing
with the lower groove in the male die.
If required, the vessels may be made slightly conical and if a rim is required to
be put on stamped goods or dishes, the dies can be made to accommodate themselves
to the shape.
If any indentation of any pattern is required on the bottom or end it can be
produced by making the die of the required conformation.
Vessels capable of being manufactured or partly manufactured by means of this
invention can be produced at very much less cost than by the ordinary process, and
the articles, when made, have a very much better finish.
The size and shape of my dies and the curved grooves therein can be altered or
modified without departing from the nature of this invention.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent. Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN THE MANUFACTURE OF PLATE OR SHEET
METAL HOLLOW-WARE" 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 the manufacture of hollow-ware such as cans, pans,
pails, dippers, coffee and spice tins, or the like from plate or sheet metal. The said
invention comprises the employment of two dies suitably constructed and arranged
to operate together to secure the bottom or top of a can or similar article to the
sides or body portion thereof by a close and firm joint, and also to turn over or
round the edge or edges of the sides or body portion of such article, so as to form
a beaded rim all substantially as hereinafter described.
In the accompanying drawing
Figures 1 and 2 represent in perspective respectively a male and female die
adapted to be used in the manufacture of hollow ware according to this invention.
Figures 3 and 4 represent in perspective respectively the sides or body portion
and the bottom or top of a can properly prepared and ready to be operated upon
by the dies in figures 1 and 2.
Figure 5 is an elevation partly in vertical section showing the sides or body
portion and the bottom or top of a can in position for the dies to operate thereon.
Figure 6 is a similar elevation showing the can, after it has been operated upon
by the dies.
Figure 7 shows in sectional elevation a die adapted for two sizes of cans:
Figures 8, 9, 10, and 11 are sectional views hereinafter referred to.
B represents a male die and D a female die. The male die B has an enlarged
base F, and a central cylindrical portion G.
This central portion G, on its outer surface or side at its lower end connects
with a groove B¹ in the base F, which groove is substantially semi-circular in cross
section. The interior periphery or wall H, of the female die D tapers inwardly
slightly, as shown in cross section, and terminates in a groove D¹, substantially
semi-circular in cross section, in the bottom J of the die D.
As shown, the dies are constructed for a cylindrical can or the like with flat or
square ends.
The operation of the dies is substantially as follows, that is to say- -The sides
or body portion A, which is of sheet metal or the like having been first cut to the
proper size is bent or formed into the shape shown in figure 3, and of a diameter
internally corresponding to the diameter of the central portion G of the die B; its
ends preferably being lapped as shown at A' and secured together by solder, or in
any other suitable manner.
.
The bottom or top C, which is also of any suitable sheet material is cut out in
circular form and struck up or shaped so as to form thereon a narrow, rim or

page_text: flange K, as shown in figure 4, the external diameter of the rim or flange corre-
sponding to the internal diameter of the side or body portion A.
The side or portion A, is then placed over the central portion G, and the bottom
or top C inserted therein, its flat surface resting on the upper surface or end L of
the central portion G, and its flange or rim being uppermost. The die D, is next
placed over the end a, of the body portion, as shown in figure 5, its tapering
interior facilitating this operation, and then the whole is placed in any suitable
press, the two dies being pressed or forced together until the die D comes to rest ou
the upper end of the central portion G of the die B, with the bottom or top C
between the two.. As the two dies come together the edge b of the body portion A,
is forced down to and into the groove B¹, and following its line of curve it is bent
or turned over so as to form a beaded rim as shown at A¹ figure 6; at the same
time the edge a is forced into the groove D¹ of the die D and along its line of
curve and is bent or turned over the edge d of the flange or rim K, of the top C.
When the dies are pressed closely together, the seam or joint thus formed will be
firmly and closely compressed as shown in figure. 6. The dies are next taken from
the press the die D removed from the lower die B and the can lifted from the latter
when the said can is ready for use. The central portion G, of the die is of a
diameter corresponding to the internal diameter of the can or other article to be
made, and its height or length corresponds to the height or length of the can,
allowing for the turning over of the edges a, b, as stated; so that, as the two. dies
operate upon the parts A, and C, the two edges a b, of the portion A, will be
properly turned as described. The dies and the width and depth of their grooves
are constructed and arranged also in reference to the thickness of the sheet material
used.
In Figure 7 the die D, is shown as having two parts M, and Q, the one smaller
than the other, so that two diameters or sizes of cans, etc can be operated upon by.
this die.
If desired the groove B' of the die B, can be dispensed with, when the edge b, of
the body portion A is not to be turned but left straight, as shown in cross section
in figure 8, such die being used for cans etc which are to be provided with a lid or
cover.
The sides or body portion A of the can, etc, can be more or less tapering
or conical, as shown in cross section in figure 9 the central portion G being
correspondingly shaped.
Also the bottom and sides or body portion can be in one piece, struck up or
formed in any suitable manner, its sides being either straight or more or less:
conical or tapering as shown in cross section in figure 10 In such case only the
edge b, will be operated upon and that by the groove B¹, of the die B, dispensing
with the groove D¹ in die D.
All sizes of articles can be made, the dies being constructed accordingly, also any
suitable sheet material may be used. Handles, etc may be secured to the cans if
desired.
In Figure 11, the end L, of the central portion G is shown as having a
depression, in the form of a star, by which such form can be pressed or formed in
the bottom or top C. In lieu of a star any suitable design or letters etc, can be
used.
A can or the like formed of sheet metal and having its bottom or top secured to
its sides or body portion, and its outer edge turned over according to this invention
has many advantages, it obviates the necessity of a wire at the edge of the body
portion; the bottom is secured by a close and tight joint, which will not leak,
thereby rendering unnecessary the use of solder, which is objectionable when the
can is to be used for materials containing acids; and the parts all secured together
and the edge turned at one operation.
'
The cans instead of being cylindrical may be square or triangular or of other
suitable shapes, it is preferable however to make them cylindrical.

page_text: The walls H of the die D, can be straight, and not taper as shown, but it is
preferable to have them taper a little.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
-
First. In the manufacture of plate or sheet metal hollow-ware, turning the edge
or beading the rim of the article being operated upon by forcing the body thereof
upon a male die so as to make its edge enter and conform to the curvature of a
groove forined in the lower end of the latter, substantially as described.
Second. In the manufacture of plate or sheet metal hollow-ware, joining the
bottom or end and the body of the article being operated upon by curling or
bending the edge of the said body over a flange formed upon the said bottom or
end, by means of a curved groove in a female die, substantially as described.
Third. The combination with a die B having a central portion G, of a die D
having a groove D¹, substantially as, and for the purpose specified.
Fourth. The combination with a die B having a central portion G and a
groove B¹, of a die D having a groove D¹, substantially as, and for the purpose,
specified.
