AN IM- PROVED PROCESS AND APPARATUS FOR CLEANSING OR PURIFYING CASKS
Year: 1873

page_text: LETTERS PATENT to Henry Bernoulli Barlow, of Manchester, in the
County of Lancaster, Patent Agent, for the Invention of "AN IM-
PROVED PROCESS AND APPARATUS FOR CLEANSING OR PURIFYING CASKS."-A
communication from abroad by Nicolas Joseph Galland, of Paris,
France, Engineer.
Sealed the 19th August 1873, and dated the 26th March 1873.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition, on
the 26th March 1873.
I, HENRY BERNOULLI BARLOW, of Manchester, in the County of
3 Lancaster, Patent Agent, do hereby declare the nature of the said
Invention for "AN IMPROVED PROCESS AND APPARATUS FOR CLEANSING OR PURI-
FYING CABKS," a communication to me from abroad by Nicolas Joseph
Galland, of Paris, France, Engineer, to be as follows:-
It is sometimes customary to prepare the interior of beer and other
casks by coating them with a thin layer of hot pitch or tar, and after
the casks so prepared have been used it is necessary to remove the said

page_text: coating and to cleanse or purify the interior before another coating is
applied.
Now this Invention consists in applying superheated steam for
cleansing and purifying casks.
A convenient apparatus for carrying the Invention into operation
consists of a stove in which is a coil of pipes supplied with steam from
a boiler. The steam is superheated in passing through this coil of pipes
and is conveyed through a swivel nozzle into the cask to be purified.
By this means the requisite heat is obtained without injuring the wood
of the cask. The upper part of the stove may be closed by the cistern
in which the pitch is heated for coating casks.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bernoulli Barlow in the Great Seal Patent
Office on the 24th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of March, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Bernoulli Barlow, Her special licence
that I, the said Henry Bernoulli Barlow, my executors, administrators, and
assigns, or such others as I, the said Henry Bernoulli Barlow, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED PROCESS AND
APPARATUS FOR CLEANSING OR PURIFYING CASKS," being a communication to
me from abroad by Nicolas Joseph Galland, of Paris, France, Engineer,
upon the condition (amongst others) that I, the said Henry Bernoulli
Barlow, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly

page_text: describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Bernoulli Barlow, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement (that is to say) :-
It is sometimes customary to prepare the interior of beer and other
casks by coating them with a thin layer of hot pitch or tar, and after
the casks so prepared have been used it is necessary to remove the said
coating and to cleanse or purify the interior before another coating is
applied.
Now this Invention consists in an improved process and apparatus for
cleansing and purifying casks, whereby the requisite heat is obtained
without injuring the wood of the cask.
And in order that the Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 represents a vertical section of the apparatus, and Fig. 2 is a
horizontal section of the same. The apparatus consists of a cylindrical
stove A surrounded by a sheet metal casing a, the whole being supported
on feet on which the grate B rests. The stove is closed by the lid V,
which is provided with a flange fitting in a circular groove in the annular
rim o, and this groove is filled with fire-clay, sand, or other suitable
material to form an air-tight lute. To the left-hand side of the stove is
the cast iron chamber C, in which is the self-acting float and valve c, the
object of which is to let off the water of condensation from the steam
which is admitted to the chamber through the pipe D. The steam is
generated in an ordinary boiler, and may be superheated or not. The
steam thus deprived of moisture passes through the pipe E outside the
stove or through it, and enters at f into the pipe F, which is in direct
communication with the pipe G, the outer end of which enters into the
cask to be cleansed or purified. The end of the pipe G may be provided
with a rose to distribute the steam in the cask. The products of com-
bustion and heated gases from the coke on the grate B pass off into the

page_text: chamber H, which is provided with a partition 7, and mix at f with the
steam from the pipe E. The steam combined with the products of com-
bustion and heated gases pass together into the cask. By this means
the requisite heat is obtained for melting and removing the coating of
pitch or tar when it has been applied and for otherwise cleansing and
purifying the cask without injuring the wood of which the cask is made.
The little door ¹ in the chamber H is to allow the cinders carried
Both the
forward by the products of combustion to be removed.
chambers C and H are provided with manholes to facilitate cleaning.
Having thus stated the nature and particulars of the Invention com- ]
municated to me by the within-named Nicolas Joseph Galland, I declare
that I claim the use of steam, whether superheated or not, combined
with the products of combustion from a stove, for removing the pitch or
tar or otherwise cleansing and purifying casks, and the apparatus shewn
and described for effecting the same.
In witness whereof, I, the said Henry Bernoulli Barlow, have
hereto set my hand and seal, this Twentieth day of September
One thousand eight hundred and seventy-three.
