BOYACIONAL DELICATION.
Improvements in the Manufacture of Metallic Casks, Drums,
and the like.
A communication from abroad by PAUL BOUQUIÉ, of Namur, in the Kingdom of
Belgium, Engineer.
I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County
of Middlesex, Chartered Patent Agent, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to the manufacture of metallic casks, drums and the like
by stamping, pressing or embossing, so that a cask is formed without the use of
rivets or the like.
The cask may be pressed of the usual bulge form or it may be in the form of a
drum or other shape, and may have one bottom piece formed therewith, the metal
of the sides and bottoms being pressed out into strengthening ribs at different points,
so as to permit of a light sheet of metal being employed. One of the bottom (or
top) pieces may have similar ribs formed thereon, and may be formed with a fold
or turned down portion which engages with the top edges of the cask, the two being
soldered or secured together. One or both of the bottom or top pieces may be
pressed into a concave form so as to afford additional strength to the cask.
In another form of cask constructed according to my invention I form the cask
in two portions, consisting each of a bottom or top piece and a portion of the body,
the two being joined together by interlocking folds which may form one of the
strengthening ribs of the cask, said fold being suitably soldered or brazed to secure
it together. Each of the parts so formed may be of the full size that the press or
apparatus employed is capable of making, and thus a cask double the size which the
press would otherwise produce may be formed.
The casks produced as before described may be tinned, enamelled, varnished,
galvanized or otherwise lined or coated according to the uses to which they are to
be placed.

Improvements in the Manufacture of Metallic Oasks, Drums,
and the like.
A communication from abroad by PAUL BOUQUIÉ, of Namur, in the Kingdom of
Belgium, Engineer.
I, PHILIP MIDdleton Justice, of 55 and 56 Chancery Lane in the County
of Middlesex Chartered Patent Agent, do hereby declare the nature of this inven-
tion 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 metallic casks, drums and the like
by stamping pressing or embossing so that a cask is formed without the use of rivets
or the like.
The cask may be pressed of the usual bulge form or it may be in the form of a
drum or other shape, and may have one bottom piece formed therewith, the metal
of the sides and bottoms being pressed out into strengthening ribs at different points,
so as to permit of a light sheet of metal being employed. One of the bottom (or
top) pieces may have similar ribs formed thereon, and may be formed with a fold or
Price d

page_text: turned down portion which engages with the top edges of the cask, the two being
soldered or secured together. One or both of the bottom or top pieces may be
pressed into a concave form so as to afford additional strength to the cask.
In another form of cask constructed according to this invention, the cask is formed
in two portions, consisting each of a bottom or top piece and a portion of the body,
the two being joined together by interlocking folds which may form one of the
strengthening ribs of the cask, said fold being suitably soldered or brazed to secure
it together. Each of the parts so formed may be of the full size that the press or
apparatus employed is capable of making, and thus a cask double the depth which
the press would otherwise produce may be formed.
To clearly explain the invention there are illustrated in the accompanying
drawings some different forms of vessels constructed according to same in which :-
Figure 1 is a view of a bulge cask one half being in elevation and the other in
section.
Figure 2 is a similar view of a drum and
Figure 3 is a portion of a bulge cask on an enlarged scale showing the manner of
joining portions of a cask by the interlocking folds above described.
In these figures a represents the strengthening ribs pressed out of the metal of
the body of the cask or drum while are similar ribs concentric or otherwise pressed
out of bottom and top pieces. In Figures 1 and 2 it will be seen that the bottoms
of the vessels are formed in one piece with the body portions, that in Figure 1
being pressed into a concavo convex form for the sake of the increased strength it
affords. The tops in both these views are shown as having edges e which have
been pressed up and down into a U shape said edge engaging with the top edge of
the cask, to which it may be secured by soldering or otherwise if required.
In Figure 3 the top is shown as connected to the body portion by an interlocking
fold d the edges of said top and body having been turned over for this purpose so
as to engage with each other. A small quantity of solder e may be run around the
fold when completed so as to make a tight joint. Said fold as before stated forms
an additional strengthening rib. It may either be employed for connecting the two
halves or portions of a cask together each portion being provided with a top
or bottom or end or not or for connecting the top or bottom to the body. The
casks as before described may be tinned enamelled, varnished, galvanized or other-
wise lined or coated according to the uses to which they are to be placed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed (as communicated to me
by my foreign correspondent) I declare that what I claim is :-
1. The improvements in the manufacture of metallic casks, drums and the like
which consists in forming same from a light sheet of metal stiffened by ribs pressed
out of it substantially as described.
2. The improvement in the manufacture of metallic casks drums and the like
which consists in pressing an end or bottom and the body or a portion of same from
a light sheet of metal, and the lid or other end from another piece all the parts
having stiffening ribs pressed out of them substantially as described.
3. In the manufacture of metallic casks, drums and the like from light sheet metal
having stiffening ribs pressed from same, the method of joining two parts by means
of an interlocking fold substantially as described.
4. The improved metallic casks or drums, constructed substantially as described.
