IMPROVEMENTS IN ATTEM- PERATORS
Year: 1871

page_text: LETTERS PATENT to James Turnock, of Ross, in the County of
Hereford, Brewer, for the Invention of "IMPROVEMENTS IN ATTEM-
PERATORS."
Sealed the 7th November 1871, and dated the 3rd June 1871.
PROVISIONAL SPECIFICATION left by the said James Turnock at
the Office of the Commissioners of Patents, with his Petition, on the
3rd June 1871.
I, JAMES TURNOCK, of Ross, in the County of Hereford, Brewer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
ATTEMPERATORS,' to be as follows:-
My Invention consists of a cylinder open at both ends for the inner
surface, around which are fixed a series of strips bent and attached in a
slanting direction forming a spiral water way from the inlet at the top
screwing round the cylinder to the outlet at the bottom. The passage

page_text: or water way may be about two inches wide and three-eighths of an
inch thick. The cylinder is supported in a vertical position by spars
passing from the bottom end of the cylinder to a centre flange or foot
placed about eight inches below the bottom of the cylinder. The flange
or foot is fitted with screw bolts to the bottom of a tun or other vessel in 5
which the cylinder is contained, and the outlet pipe passes through the
centre of the base or foot.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Turnock in the Great Seal Patent Office
on the 2nd December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
TURNOCK, of Ross, in the County of Hereford, Brewer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of June, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Turnock, Her special licence
that I, the said James Turnock, my executors, administrators, and
assigns, or such others as I, the said James Turnock, 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
ATTEMPERATORS," upon the condition (amongst others) that I, the said
James Turnock, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 Turnock, do hereby declare
the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by
the following statement thercof, that is to say :-
My Invention consists of a cylinder open at both ends for the inner
surface, around which are fixed a series of strips bent and attached in a
slanting direction forming a spiral water way from the inlet at the top
screwing round the cylinder to the outlet at the bottom. The passage
or water way may be about two inches wide and three-eighths of an
inch think. The cylinder is supported in a vertical position by spars
passing from the bottom end of the cylinder to a centre flange or foot
placed about eight inches below the bottom of the cylinder. The flange
or foot is fixed with screw bolts to the bottom of a tun or other vessel in
which the cylinder is contained, and the outlet pipe passes through the
centre of the base or foot.
In order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the Drawings hore-
Figure 1 is a perspective view of the apparatus mounted in its place
within a brewer's "gyle tun" or fermenting tun; Figure 2 is a vertical
section to a larger scale.

C
a is a double cylinder, by preference of sheet copper tinned on the
surface, and open at the top and bottom. Enclosed within the double
cylinder a there is a spiral passage a¹ with an inlet at a³ and an outlet
pipe a. b, b, are legs supporting the cylinder from the bottom of
the tun or vessel & containing the liquor of which the temperature is
required to be regulated. The size of this tun or vessel may be varied
to any required dimensions, the depth being such that the cylinder
is completely immersed. Cold or warm water is admitted to the attem-
perator at the top inlet a³ and flows through the water way, passing
out at the bottom outlet a³.
The apparatus is built or put together in the following manner :-A
series of strips of tinned copper, or it may be of copper or tin, are
soldered to the inner cylinder of same material, which is mounted on
spars.or legs attached to a bottom flange. The outer cylinder which is
made to fit accurately is then put on, and the joints at the top and

page_text: bottom are soldered. The quantity of water admitted is not sufficient
to fill the chambers of the attemperator, so that it is much divided in
its passage through. The water is allowed to flow out uninterruptedly
at the lower end. By the use of this attemperator a very perfect control
of the fermentation is obtained with great economy of water.
Having thus described the nature of my said Invention and the
manner of performing the same, I would have it understood that I
claim, the construction of attemperators substantially as described.

In witness whereof, I, the said James Turnock, have hereunto set
my hand and seal, this First day of December, in the year of our
Lord One thousand eight hundred and seventy-one.
