page_text: PROVISIONAL SPECIFICATION.
Improvements in Barrels and other Receptacles for Liquids.
I, BERNHARD POLITZER, of I Graben No. 29, Vienna, Purveyor of Machines to the
Court, do hereby declare the nature of this invention to be as follows:-
This Specification relates to the construction of barrels entirely of metal without.
changing their shape. In this way the barrels will be more manageable when used
for conveying goods to a distance.
These steel barrels will serve either for petroleum or other oil, beers and any other
liquids which hitherto have been conveyed in wood barrels or cylindrical metal
cans.
I form my improved barrels, as follows.
The body or wall is formed in three horizontal parts, two slightly conical forming
the end pieces, and one broad band in the middle, the latter being slightly concave.
The two end pieces or heads, are formed of flat discs with their edges turned up
towards the end of the wall, which is turned over so as to clip the edge of the head.
Outer hoops can also be used if desired.
The several parts are securely rivetted together, and a flanged socket is similarly
attached to form the bung-hole and tap-hole.
Dated this 22nd day of May 1895.

COMPLETE SPECIFICATION.
Improvements in Barrels and other Receptacles for Liquids.
I, BERNHARD POLITZER, Machine Manufacturer, of Rudolfsplatz 10 (late of
I Graben 29) Vienna, in the Empire of Austria, 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 :—
This invention relates to casks made completely of metal plates in form of the
present wood casks, as being more convenient for rolling and moving, such metal
plate casks being especially suitable for petroleum, oils, beers and other liquids
hitherto stored in wood casks or metal drums.
The mode of performing this invention is as follows ;-
In the annexed drawing, Fig. 1 shows a plan view of the cask; Fig. 2 a
longitudinal section, Figs. 3, 4 and 5 parts composing the cask and Fig. 6 the manner
of joining the cask ends with the sides.
The cask is formed by a middle band a and conical bands & rivetted together, as in
Fig. 2, by rivets c or by welding. The bottom and cover B and C are then folded in
the manner shown in Fig. 6 and welded or rivetted, the edge d projecting after
rivetting being bent over the side of the cask edge in order that the latter is
covered.
The bung is constructed in the following manner.
A metallic ring e is welded or rivetted on the cask.
in which a plug is screwed; the latter has the usual
the usual bung gas shown in the drawing.
This ring has a female screw
bung-hole which is closed by

page_text: The bung thus constructed will allow a cask in case of need to be repaired by
screwing out the plug and so obtaining a large opening through which a man may
pass into the interior of the cask.
The casks made in the above manner receive, by rivetting or welding the parts
partlyyone in the other, an extraordinary strength and resistance that hitherto nas
been obtained by no cylindrical or other metallic cask. According to the size of the
cask, one middle band a can be used and two or more side bands b.
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 :-
Casks made of metallic plates consisting of the band a and conical bands 6 which
are lap rivetted or welded to form the barrel A to which the bottom and the cover B
and are rivetted, the borders of the barrel being bent over for the purpose of
strengthening the edges of the cask, and the bung-hole formed by a metal ringe
rivetted or welded in the cask with bung plug f screwed in said ring e, all substantially
as illustrated and described.
Dated this 20th day of February 1896.
