IMPROVEMENTS IN MASHING ATTEMPERATORS
Year: 1861

page_text: LETTERS PATENT to Joseph Lush, of St. George's Square, Portsea, in
the County of Hants, Brewer, for the Invention of "IMPROVEMENTS IN
MASHING ATTEMPERATORS."
Sealed the 21st March 1862, and dated the 30th September 1861.
PROVISIONAL SPECIFICATION left by the said Joseph Lush at the
Office of the Commissioners of Patents, with his Petition, on the 30th
September 1861.
I, JOSEPH LUSH, of St. George's Square, Portsea, in the County of Hants,
Brewer, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN MASHING ATTEMPERATORS," to be as follows:-
The object of this Invention is to avoid the injurious effects of what are
known in brewings as "raw worts," by which much of the useful portion of
the malt is lost, and the quality of the beer is deteriorated; this is obviated
by the use of my Invention, which raises the temperature of the mash to any
required heat, and retains it at such temperature as long as may be required,
and in a manner which produces no damage to the mash, as is the case with
most if not all the mashing attemperators at present in use.
For the purpose of carrying out my improvements, I fix in the mash tun
an upright shaft, which is carried at the top by suitable bearings, and at the

page_text: bottom by a shoe or step fixed in the bottom of the mash tun; this shaft is
caused to revolve by gearing, driven by steam, or other motive power, and it
is made hollow for a portion of its length to carry the steam and water
required in using the attemperator; into this shaft are bolted or otherwise
secured one or more armis, which are placed at right angles to the upright
shaft close to the false bottom of the mash tun, and are carried nearly to the
length of the inside diameter of the mash tun. On to each of these arms are
cast one or more flanges, and to these flanges are fixed by bolts or otherwise
vessels of copper or other material of suitable shape (which may be either
round or oval, parallel, coned, or otherwise), which stand upright on the arm
or arms, and which are therefore parallel with the upright shaft; these copper
vessels are connected at the top to an arm which is fixed above them on the
upright shaft, and which is perfectly parallel with the lower arm; and where
more than one copper vessel is used on each arm they are formed hollow, so
that the copper vessels may be in communication with one another; these
vessels are filled with heated water up to a point indicated by a guage cock
fixed in the side of the vessel, and they are furnished with a safety valve to
remove any superfluous pressure, and a thermometer to indicate the tempera-
ture of the water in the interior of them, and each copper vessel is furnished
with a pipe descending from the top arm nearly to the bottom inside of it, and
connected with a regulating cock to the upright hollow shaft. The top of this
upright hollow shaft is furnished with a stuffing box and gland forming a
joint for the pipe or pipes supplying steam or water, as required, to the
attemperator.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Lush in the Great Seal Patent Office on the 29th
March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
LUSH, of St. George's Square, Portsea, in the County of Hants, Brewer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Lush, Her special licence that I, the said Joseph Lush,

page_text: my executors, administrators, and assigns, or such others as I, the said
Joseph Lush, 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
MASHING ATTEMPERATORS," upon the condition (amongst others) that I, the
said Joseph Lush, my executors or administrators,. by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Lush, 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 fol-
lowing statement thereof, that is to say:-
The object of this Invention is to avoid the injurious effects of what are
known in brewings as "raw worts," by which much of the useful portion of the
malt is lost; and the quality of the beer is deteriorated; this is obviated by the
use of my Invention, which raises the temperature of the mash to any required.
heat, and retains it at such temperature as long as may be required, and in a
manner which produces no damage to the mash, as is the case with. most, if
not all, the mashing attemperators at present in use..
For the purpose of carrying out my improvements, I fix in the mash tun
an upright shaft, which is carried at the top by suitable bearings, and at the
bottom by a shoe or step fixed in the bottom of the mash tun; this shaft is.
caused to revolve by gearing driven by steam or other motive power, and it is
made hollow for a portion of its length to carry the steam and water required.
in using the attemperator. On to this shaft are bolted or otherwise secured one
or more arms, which are placed at right angles to the upright.shaft close to
the false bottom of the mash tun, and are carried nearly to the length of the
inside diameter of the mash tun. On to each of these arms are cast one or
more flanges, and to these flanges are fixed by bolts or otherwise vessels of
copper or other material of suitable shape (which may be either round or oval,,
parallel, coned, or otherwise), which stand upright on the arm or arms, and
which are therefore parallel with the upright shaft; these copper vessels are
connected at the top to an arm. which is fixed above them on the upright.

page_text: shaft, and which is perfectly parallel with the lower arm; and where more
than one copper vessel is used on each arm they are formed hollow, so that
the copper vessels may be in communication with one another; these vessels
are filled with heated water up to a point indicated by a gauge cock fixed in
the side of the vessel, and they are furnished with a safety valve to remove
any superfluous pressure, and a thermometer to indicate the temperature of
the water in the interior of them, and each copper vessel is furnished with a
pipe descending from the top arm nearly to the bottom inside of it, and con-
nected with a regulating cock to the upright hollow shaft. The top of this
upright hollow shaft is furnished with a stuffing box and gland forming
a joint for the pipe or pipes supplying steam or water, as required, to the
attemperator.
And in order that my Invention may be most fully understood and readily
carried into practice. I will proceed to describe the Drawing hereunto

page_text: the main centre shaft, as well as to the particular method of applying the
supply of liquor and steam to the apparatus, without departing from the
principle of my Invention, which consists in arranging apparatus for raising
the temperature of the mash to any required degree of heat, and retaining
at such temperature, as long as required, by the means herein described.
In witness whereof, I, the said Joseph Lush, have hereunto set my hand
and seal, this Twenty-seventh day of March, in the year of our Lord
One thousand eight hundred and sixty-two.
Witness,
