page_text: LETTERS PATENT to Frank Wirth, of the Firm of Wirth and Company, Patent
Solicitors, at Frankfort on the Main, in the Empire of Germany, for the
Invention of "IMPROVEMENTS IN CASKS, BARRELS, HOGSHEADS, AND THE LIKE
VESSELS." A communication from Jules Boehin, of Bastide, Bordeaux, in the
Republic of France
Sealed the 27th December 1879, and dated the 21st July 1879.
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office of
the Commissioners of Patents on the 21st July 1879.
FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort on the Main, in the Empire of Germany. "IMPROVEMENTS IN CASKS, BARRELS,
HOGSHEADS, AND THE LIKE VESSELS." [A communication from Jules Boehm,
of Bastide, Bordeaux, in the Republic of France.]
Bottled beer when warmed in a water bath is preserved from any injurious
fermentation, and can thus be kept for a longer time and in better condition than
beer which has not been thus warmed.
The object of the present Invention is to provide a metal cask hermetically closed
at all joints, and in which beer and other effervescent and fermenting liquids can
be thus warmed, and then exported with perfect security.
In carrying the said Invention into practice I construct a cask consisting of two
equal parts or divisions, upper and lower. Each part is provided with a flange at
the end where the two parts fit together, said flanges being provided with holes
into which screw bolts are fitted to draw the said two parts firmly together;
between the said flanges is placed a packing which is prevented from slipping by a
projecting rim on the upper part or division. A projecting flange is provided at
the end of each division, and these flanges, together with the first named flanges,
support the cask when the same is being rolled along, in such a manner that no
part thereof except the said flanges come in contact with the ground.
The said cask is provided with two openings, one for the bung and the other for
the tap; these openings are strengthened on the inside by a collar. The bung is
provided with a packing ring, so as to fit air tight.. The opening for the tap is
closed with a cork or plug which is longer than the opening, so as to form a head
on the inside. The cork or plug is also held by a mouth piece, so that it cannot be
driven out by the pressure from within.
The said opening for the tap is provided with a screw thread on its outer side,
upon which the tap can be fitted. I employ a pressure cock as the tap, the com-
pressed air being admitted by a pipe and passing into the barrel. Any suitable
cock can however be used.

FRANK WIRTH, of the Firm of Wirth and Company, Patent Solicitors, at Frank-
fort-on-the-Main, in the Empire of Germany. "IMPROVEMENTS-IN-CASKS, BARRELS,
HOGSHEADS, AND THE LIKE VESSELS." A communication from Jules Boehm,
of Bastide, Bordeaux, in the Republic of France.
Bottled beer when warmed in a water bath is preserved from any injurious
fermentation, and can thus be kept for a longer time and in better condition than
other beer which has not been thus warmed.
The object of the present Invention is to provide a metal cask which is hermeti-
cally closed at all joints, and in which beer and other effervescent and fermenting
liquids can be thus warmed and then exported with perfect security.
In the accompanying Drawing,―-
Figure 1 represents in elevation a cask constructed according to my Invention,
the same being best made of cast iron, which can be enamelled if desired.
Figure 2 is a vertical section of the same.
Figure 3 is a sectional view illustrating the manner of applying a cock or tap to
the said cask.
The cask consists of two equal parts, A and A'. Each part is provided with a
flange H, the said flanges being provided with holes a into which screw bolts B are
fitted to draw the two parts A and A' firmly together; between the flanges H is
placed a packing C, which is kept from slipping by the projecting rim f on the
part A.
The projecting flanges D, together with the flanges H, support the cask when the
same is being rolled along in such a manner that no part of the cask except the said
flanges come in contact with the ground. The said cask is provided with two
openings or holes, the one E for the bung, the other M for the cock or tap; these
holes are provided on the inside with a collar to afford strength at these parts. The
bung is provided with a packing ring, so as to fit air tight. The opening M is
closed with a cork or plug which is longer than the opening, so as to form a head at
the inside. The cork or plug is also held by a net mouth piece, so that it cannot be
driven out by the internal pressure.
The hole M is provided with a screw nipple on its outer side upon which the cock
or tap R can be fitted. I prefer to employ a pressure cock or tap constructed as
shewn, so that the compressed air is admitted by the pipe P, and passes by F, P¹,
-into-the-barrel Any suitable cock may however be used.
Having thus fully described the said Invention, and the manner-of-performing
the same, I wish it understood that I claim,―
First. The metal cask as above described, and shewn in the Drawing, for the
purpose specified.
Second. The cock, as described and shewn in the Drawing, applied to the cask,
substantially in the manner and for the purpose specified.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand
and seal, this Ninth day of January, in the year of our Lord One thousand
eight hundred and eighty.
