AND DISTILLERIES."
Sealed the 29th August 1862, and dated the 9th May 1862.
PROVISIONAL SPECIFICATION left by the said James Oxley at the
Office of the Commissioners of Patents, with his Petition, on the 9th
May 1862.
I, JAMES OXLEY, of Frome, in the County of Somerset, Brewer's Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR FACILITATING THE PROCESSES OF MASHING AND SPARGING IN
BREWERIES AND DISTILLERIES," to be as follows:-
My Invention has for its object, the raising in temperature of the contents
of the mash tun, by drawing the wort from the bottom thereof and conveying
it to a pan or receiver, where it is heated by steam, and thence discharged
over the grain contained in the tun. For this purpose a screw conveyor or
pump is adapted and applied to the bottom of the tun, by means of which the
wort is conveyed through a pipe to a pan or receiver at the top of the tun,
such pan or receiver containing a coil of pipes heated by steam. From this
pan or receiver the wort descends by a pipe into the sparger, which is pro-
vided with arms composed of two tubes, one within the other; the outer tube

page_text: having two sets of perforations, one set larger and the other smaller, and the
inner tube having one set corresponding with the larger perforations in the
outer tube. The tubes are made so that the outer tube can be turned in such
a manner as to admit of a discharge of the contents of the inner tube either
through the smaller or larger perforations of the outer tube as required. By
this arrangement the wort and liquid, after being heated in the pan or receiver,
are re-distributed over the grain in the tun, thereby raising the temperature
in the same as required. The waste steam from the coil of pipes in the pan
or receiver may be discharged into the closed top of the mash tun for the
purpose of maintaining the required temperature.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Oxley in the Great Seal Patent Oflice on the 8th
November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
OXLEY, of Frome, in the County of Somerset, Brewer's Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Oxley, Her special license that I, the said James Oxley,
my executors, administrators, and assigns, or such others as I, the said
James Oxley, 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
"IMPROVEMENTS IN APPARATUS FOR FACILITATING THE PROCESSES OF MASHING AND
SPARGING IN BREWERIES AND DISTILLERIES," upon the condition (amongst others)
that I, the said James Oxley, by an instrument in writing under my hand
and seal, should particularly 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 James Oxley, do hereby declaro
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the

page_text: following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
:-
My Invention of "Improvements in Apparatus for Facilitating the Processes
of Mashing and Sparging in Breweries and Distilleries," has for its object the
raising in temperature of the contents of the mash tun, by drawing the wort
from the bottom thereof, and conveying it to a pan or receiver, where it is
heated by steam, and thence discharged through the sparger, constructed as
herein-after described, over the grain contained in the tun.
For this purpose
a screw conveyer or a pump is adapted and applied to the bottom of the tun,
by means of which the wort is conveyed through a pipe to a pan or receiver
at the top of the tun, such pan or receiver containing a coil of pipes beated by
steam. From this pan or receiver the wort descends by a pipe into the.
sparger, which is provided with arms, composed of two tubes, one within the
other, the outer tube having two sets of perforations, one set larger, and the
other smaller, and the inner tube having one set corresponding with the larger
perforations in the outer tube. The tubes are made so that the outer tube can
be turned in such a manner as to admit of a discharge of the contents of the
inner tube, either through the smaller or the larger perforations of the outer tube
as required. By means of the sparger, constructed in this manner, the wort
and liquid after being heated in the pan or receiver are redistributed over the
grain in the tun, thereby raising the temperature in the same as required.
The waste steain from the coil of pipes in the pan or receiver may be dis-
charged into the closed top of the mash tun, for the purpose of maintaining
the required temperature.
Having thus stated the nature of the said Invention, I will proceed to
describe more particularly in what manner the same is to be performed, by
reference to the accompanying Drawing, in which are represented the parts
above referred to.
DESCRIPTION OF DRAWING.
Fig. 1 is a section of the mash tun, with the heating apparatus and sparger
above referred to: Figures 2 and 3 represent portions of the outside tubes of
Fig. 1 is a section of the mash tun, with the heating apparatus and sparger
above referred to: Figures and 3 represent portions of the outside tubes of
the
sparger on an enlarged scale; Figures 4 and 5 represent the same in cross
section on a still larger scale. In these several Figures the same letters of
reference indicate corresponding parts.
A is the ordinary mash tun; B is a pipe at the bottom of the tun, through
which the wort is drawn when the grain has been mashed; C is a pump (or a
screw may be used), by means of which the wort is forced through the pipe D
into a pan or receiver E on the top of the tun. This pau contains a coil of

page_text: pipes, into which steam or heating vapour is admitted, and the wort becomes
beated by its contact therewith; F is a pipe, through which the heated wort
descends into the sparger G, which is constructed with two arms H, H, com-
posed of double tubes with perforations in them, arranged as shown in Figures
2, 3, 4, and 5. Through the perforations in these tubes, the wort is re-
distributed over the grain contained in the tun, the operation being continued
until the required temperature is attained.
It will be perceived on reference to Figures 2, 3, 4, and 5, that the outer
tube I has two sets of perforations, the one set being larger and the other
smaller, and that the inner tube K has one set corresponding in size with the
large perforations in the tube I. Now, when the outer tube I is turned so as
to bring both tubes into the relative positions shewn in Fig. 4, there will be
an outlet for the liquid only from the inner tube K, through the smaller per-
forations in the outer tube I. And when the outer tube is turned into the
position shewn in Figure 5 there will be an outlet for the wort through the
larger perforations in the tube I.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, I hereby declare that I do not claim as of my
Invention the apparatus described for conveying and heating the wort, except
when used in combination with the double-tubed sparger above described,
such and similar apparatus having before been used in combination with a
sparger differently constructed; but what I do claim as of my Invention is,
the use of the sparger constructed with double tubes in the manner described,
for the purpose of re-distributing the wort and liquid over the contents of the
tun after the wort has been heated, as herein-before described.
In witness whereof, I, the said James Oxley, have hereunto set my hand
and seal, the Fourth day of November, in the year of our Lord One
thousand eight hundred and sixty-two.
