Improvements in Apparatus for Cooling and Attemperating Beer
During Fermentation.
I HENRY PRIOR Brewer Linton Cambridgeshire do hereby declare the nature
of this invention to be as follows:-
My invention relates to apparatus used in breweries for cooling and attemperating.
beer while undergoing fermentation. An apparatus constructed according to this
invention consists of a circular or otherwise shallow vessel or tray, having a closed.
top. Inside of this tray I place one or more coils of pipe, the outlet end of which
extends through the shell of the said tray, and if desired, may communicate with
one or more coils on the outside, terminating in a connection for receiving an india
rubber or other flexible pipe. The inlet end of the coil also extends through the
shell and is provided with a regulating cock and a similar connection to the outlet.
The top of the tray is fitted with a tube communicating with the inside, and serves
for filling the inside with water, and also for inserting a thermometer to ascertain
the temperature of the water. I further provide an air cock in the top for the
expulsion of air during filling. Chains or slings are attached to the tray with
suitable pulleys for raising or lowering the apparatus in the fermenting vessel as
required.
The working process is as follows:-The tray being charged with water is
lowered into the beer level with the top thereof, and cold water is caused to
circulate through the coils. The effect of this circulation is to cool the still water
in the tray to an even temperature thereby exposing a large, and uniform cooling
surface to the beer. The circulating water, after passing through the coils, is still
capable of absorbing heat and may be put through the external coils when such
are used. Thus in the manner described. I obtain a more even distribution of'.
temperature with greater control over the beer under treatment and a larger
development of yeast than hitherto. obtained by the ordinary kinds of cooling and
attemperating apparatus employed for the purposes named. My apparatus may
be constructed of any suitable metal, but generally I give preference to tinned-
copper.

Improvements in Apparatus for Cooling and Attemperating. Beer
During Fermentation.
I, HENRY PRIOR, Brewer, of Linton in the County of Cambridgeshire, do
hereby declare the nature of this invention-and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement―
My invention relates to apparatus used in breweries for cooling and attemperating
beer while undergoing fermentation. An apparatus constructed according to this
invention consists of a circular, or otherwise, shallow vessel or tray having a closed
top, inside of this tray 1 place one or more coils of pipe, the outlet end of which
extends through the shell of the said tray and if desired may communicate with
one or more coils on the outside, terminating in a connection for receiving an india
rubber or other flexible pipe. The inlet end of the coil also extends through the
shell and is provided with a regulating cock and a similar connection to the outlet.

page_text: The top of the tray is fitted with a tube communicating with the inside and serves
for filling the inside with water and also for inserting a thermometer to ascertain
the temperature of the water. I further provide an air-cock in the top for the
expulsion of air during filling. Chains or slings are attached to the tray with
suitable pullies for raising or lowering the apparatus in the fermenting vessel as
required.
The working process is as follows:-The tray being charged with water is
lowered into the beer level with the top thereof and cold water is caused to
circulate through the coils, the effect of this circulation is to cool the still water
in the tray to an even temperature, thereby exposing a large and uniform cooling
surface to the beer, the circulating water after passing through the coils is still
capable of absorbing heat and may be put through the external coils when such
are used.
Thus in the manner described I obtain a more even distribution of temperature
with greater control over the beer under treatment and a larger development of
yeast than hitherto obtained by the ordinary kind of cooling and attemperating
apparatus employed for the purposes named.
My apparatus may be constructed of any suitable metal but generally I give
preference to tinned copper.
And in order that my said invention may be fully understood I now proceed to
describe the same, reference being had to the accompanying drawing and to the
letters of reference marked thereon.
Figure 1 represents a side elevation of my apparatus which consists of a metal
tray made watertight at the top and bottom covers and round the joints on the
top cover.
Figure 2, is a plan of the same having the top cover removed to disclose the
coils of pipe inside the tray.
The tray A is filled with water through the funnel tube B which also serves to
receive a thermometer for registering the variations in the temperature of the water
inside. Care the cooling coils which will vary in number according to the size of the
apparatus: The cold water supply to the coils may enter by means of a flexible pipe
either at C¹ or C' and after traversing the coils inside the tray may be directed
through one or more outer coils as shewn by the dotted pipe C³. A small cock D
may be inserted in top cover to permit of air escaping when charging the tray with
water. The chains E are for raising or lowering the tray into the beer.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what I
claim is :-

Improvements in apparatus for cooling and attemperating beer during fermenta-
tion," substantially as herein described and set forth.
In witness whereof, I, the said Henry Prior, have hereunto set my hand and
seal this Twenty-third day of September, in the year of our Lord
One thousand eight hundred and ninety-two.
