Improvements in Barrels.
I, ADRIAN CASTANIEN, Manufacturer, of Bielefeld in the Province of Westfalia
and Kingdom of Prussia 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 :-
As a substitute for wooden barrels iron barrels have of late years to a great
extent been brought into use. The latter are without many drawbacks connected
with wooden barrels and are far better adapted for many purposes than those made
of wood.
Up to the present iron barrels were mostly stamped in many pieces, and these
pieces then connected with each other by rabbeting, welding, riveting and screwing
them together, in which processes great difficulty was however always experienced
in making the barrels tight. In short the entire manufacture from a number of
single parts was very troublesome and expensive.
It is expected that my new and simple method of manufacture will, more than
any other at present known avoid the disadvantages we have enumerated.
The barrels are first of all stamped out of sheet-iron in two equal halves, a lower
and an upper one, which are joined together in the centre-plane of the barrel. The
two heads are pressed into the interior of the barrel-half while it is being stamped,
causing at the top and bottom a raised edger of double metal and slightly slanted
inwards to appear. This edge not only stiffens the ends of the barrel and makes
then capable of standing a great amount of rough usage, but in case of a lifting-
chain being used it gives the hook a firm grip, without the hook in any way being
able to damage the barrel. The joining of the two barrel-halves is done without
any welding or soldering and without any rabbet or without any external attachment-
ring in a very simple manner. During the process of stamping, each barrel-half
receives at its broad open end, at the point where the joint is made later on, a
flat projecting rim shaped like a collar, or flange. In the one half A the rim a is
stamped from nearly double as broad a piece of metal as the rim of the other
barrel-half B, and in such a manner that it has an angular section, a vertical
rim a, forming outwardly on the horizontal marginal strip a. The strip a is just
broad enough for the rim of the other barrel-half to fit between the ring a₁ and
lie on a.
When the two barrel-halves are placed upon each other in this manner,
the rim a is by stamping turned horizontally inwards over the rim of the
To insure greater
barrel-half B, so that is now wedged in between a and a,.
tightness rivets n are put through the joint-rim C which is thus formed of three
layers of sheet-metal tightly pressed on each other. A joint made in this manner
offers a double security against the possibility of its becoming loose or leaking,
and must therefore in point of absolute reliability be preferred to all other kinds
of joints.
In the annexed drawing in Fig. 1 this very simple process of making our barrels
is represented.
Fig. 2, on the other hand, shows a modification, in which, in order to increase
the rigidity and tightness of the barrel, a ring c preferably of half-round iron shaped
section, as in the drawing, is laid into the joint which lies half in A and half in B
and in this case bulges out to a certain extent.
Another modification is represented in an unfinished state in Fig. 3 and in a
finished state in Fig. 4. In this case the height of each barrel-half is made greater
than the theoretical barrel-half by half the height of the ring c. The one half D
contains the ring c in a corresponding bulging-out d, while the other half E is

it encloses the part d of the other half up to half its height with its marginal-
ring e, correspondingly bulged out, while the upper part of this ring e goes upwards
as a straight rim (Figure 3). Thereupon this projecting part of the rim e is by
stamping pressed closely round about that part of the roll d which is still free, so
that the two barrel-halves are joined in this manner. It is true that for barrels
subjected to a great pressure inside this mode of joining is not as good as that
described in Figs. 1 and 2.
Of course suitable packing-material may be laid between the ring c and the sides
of the barrel, as well as between the parts of the latter that are pressed against each
other.
This method of construction may be also applied to other hollow bodies.
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 :
1. Iron barrels, constructed of two halves A and B, stamped out of one piece,
and joined together by pressing in the rim 6 of the one half between the two
parts a and a, of the rim of the other half.
2. Barrels, constructed as in 1., but in which rivets are put through the three
parts a, b, a, of the rim, which are pressed on and into each other.
3. Barrels, constructed as in 1., in which there is a ring c catching from the inside
against the joint C equally into a corresponding annular enlargement of each
barrel-half.
4. Barrels, constructed of two parts D and E, each stamped out of one piece, one
of which contains a ring c lying in a stamped-in, roll-shaped projection d while the
other catches with the rim e about the projection d and being firmly pressed against
the latter encloses it in such a manner that the two parts of the barrel are inseparably
joined together.
