Year: 1867

page_text: LETTERS PATENT to Francis Gregory, of the Firm of Gregory and
Haynes, of Salford, in the County of Lancaster, Brewery Machinists,
for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
PROVISIONAL SPECIFICATION left by the said Francis Gregory at the
Office of the Commissioners of Patents, with his Petition, on the
19th March 1867.
I, FRANCIS GREGORY, of the Firm of Gregory and Haynes, of Salford, in
the County of Lancaster, Brewery Machinists, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
REFRIGERATING PURPOSES USED IN BREWERIES AND DISTILLERIES,
follows:-
This Invention relates to the cooling or regulating the temperature of the
wort liquors in the process of brewing or for other purposes; and in the first

page_text: place consists in employing a series of hollow troughs framed or formed of
corrugated metal in the shape of continuous external and internal arches of
the same or of different spans with suitable ends, which series of troughs I
place in a framework or vessel of the required shape and dimensions, to
which I attach, by hinges or otherwise, another framework which supports a
number of pipes or tubes of any required shape or configuration with suitable
connections, so that the pipes or tubes fit into the hollow troughs of the
corrugated metal, allowing a space between the concavities of the corrugated
metal and pipe or pipes. At one side or end of the framework or vessel I
place a channel or trough which is connected with suitable openings with the
bottom of the trough in the corrugated metal. At the ends of the openings
in the trough or channel I place a number of valves attached to a shaft, each
of which is acted upon separately by a spring, the arrangement being such
that all can be opened and shut by one operation. In the tubes or pipes I
place one or more pipes or tubes of any required configuration with one or
both ends closed or partially closed, or timber or any solid or hollow material
may be used for the same purpose. At each end of the vessel or framework
I place a worm and wheel arranged with suitable mechanical contrivance to
raise or lower the framework (to which is attached the tubes) from or to the
corrugated metal, or by the plan described by me in the Specification of the
Letters Patent dated 29th April 1865, No. 1204. I introduce the worts to
be cooled on the surface of the corrugated metal, the worts being directed by
strips or projections along the top of the exterior pipes or tubes into the
space round the concave, surfaces of the corrugated metal and the pipes or
tubes, and over the external arches, and so on until conveyed to where
required, sufficient inclination being given to cause them to flow with freedom.
At the other end from where I introduce the worts cold water or other liquid
is admitted which passes in the space between the interior and exterior tubes
or pipes running in an opposite direction to that of the hot wort, gradually
reducing it to the temperature required. The interior pipes, tubes, or other
material causes the water to flow in a thin stream.
Another part of this Invention consists in passing a stream of cold water
under the corrugated metal with suitable divisions to cause it to flow up
and down, following the course of the corrugated metal in a thin stream until
it passes out at the same end where the hot wort is admitted; either one or
other of the streams can be used separately or conjointly as desired. I some-
times pass the hot worts through the pipes instead of the plan described.
I use it also without the interior tubes or other material named, and two

page_text: or more tubes may be placed in each trough of the corrugated metal if
desired.
It is evident that the various modifications of this apparatus can be used
for distilleries as well as breweries.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Francis Gregory in the Great Seal Patent Office on the
19th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
GREGORY, of the Firm of Gregory and Haynes, of Salford, in the County of
Lancaster, Brewery Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Francis Gregory, Her special license that I, the said Francis Gregory, my
executors, administrators, and assigns, or such others as I, the said Francis
Gregory, 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 MACHINERY OR
APPARATUS USED IN BREWERIES AND DISTILLERIES," upon the condition (amongst
others) that I, the said Francis Gregory, 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 Francis Gregory, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
This Invention consists in improved machinery or apparatus for cooling or

page_text: regulating the temperature of the wort liquors in the process of brewing, or
for other similar purposes.
The manner in which my Invention is to be performed will be clearly
understood by the following particular description thereof, reference being
had to the Figures on the accompanying Sheet of Drawings, and to the
letters of reference marked thereon.
Figs. 1 and 2 are longitudinal and transverse sections, and Fig. 3 a plan
of one arrangement of my improved machinery or apparatus; Figs. 4 and 5
are longitudinal and transverse sections, and Fig. 6 a plan of one modification;
and Figs. 7 and 8 are end and side views of another modification of the
same.
I employ a series of hollow troughs a framed or formed of corrugated
metal in the shape of continuous external and internal arches of the same or
of different spans with suitable ends, which series of troughs I place in a
framework vessel or cistern 6 of the required shape and dimensions, to which
I attach by hinges c or otherwise another framework d which supports a
number of pipes or tubes of any required shape or configuration with
suitable connections, so that the pipes or tubes fit into the hollow troughs
of the corrugated metal, allowing a space between the concavities of the said
corrugated troughs. At one side or end of the framework or vessel I place
a channel or trough f communicating by cocks 9 with the ends of the
corrugated troughs for draining the troughs when required; or at the ends of
the openings in the trough or channel I place a number of valves attached to
a shaft, and provide each valve with a spring, the arrangement being such
that all can be opened and shut by one operation. In the tubes or pipes e I
place one or more smaller pipes or tubes h of any required configuration with
one or both ends entirely or partially closed for the purpose of limiting the pas-
sage of the water or other liquid, so that in passing a given quantity through it
must flow with a greater velocity than with the full bore of the pipe; or
timber or any solid or hollow material may be used for the same purpose.
The wort from the hop beck or cooler is admitted by the pipe i, Fig. 3, into
the corrugated troughs a, the wort being directed by strips or projections ; on the
pipes underneath the said pipes e in a broad thin sheet, sufficient inclination
being given to the apparatus to cause the wort to flow and pass over the
convex arch of the first corrugated trough and underneath the next pipe, and
so on to the other side of the refrigerator, where it passes into the last concave
space k, and from thence conveyed where required by the pipe l, the corrugated
troughs being drained by the taps g and trough f. Water or other liquid is

page_text: admitted by the pipe m passing into the first pipe e, and thence conveyed by
he first connection n to the next pipe, and so on through the other connec-
tions n and pipes to the other end, where it passes out through the outlet
pipe o. I admit water or other liquid by the pipe p into the vessel or cistern b
underneath the corrugated troughs a, the passage of the liquid being directed
by the partitions q so that it follows the course of the corrugated troughs in a
thin stream until it passes out through the outlet piper, and the stream of
water may be used either separately or conjointly. The connections n to
which the pipes are fixed are secured to the hinged frame d, to which is
attached a rods connected by a chain t to a winch or other lifting apparatus,
so that all the pipes can be lifted out of their respective troughs to facilitate
their being cleaned; or I employ the plans described by me in the Specification
of the Letters Patent bearing date the Twenty-ninth day of April, in the year
of our Lord One thousand eight hundred and sixty-five, No. 1204.
In Figs. 4, 5, and 6, instead of the connections n which hold the tubes or
pipes e passing over the exterior or convex arches of the corrugated troughs,
as shewn in Fig. 8, a part of the convex arch at each alternate end is removed,
so that the connection is carried in a straight line from the end of one pipe to
the next, as shewn in the said Figs. 4, 5, and 6, thus dispensing with the
valves or taps for draining.
In Figs. 7 and 8, representing another modification of my improvements,
I place two or more pipes e in each corrugated trough or space a, either
round, as shewn in the Figures, or of any other shape or configuration. I
sometimes pass the hot worts through the pipes or tubes e instead of the
plan described, in which case the water or liquid must pass over the surfaces
of the corrugated troughs, and when desired I dispense with the interior tubes
or other material in the interiors of the pipes e. It is evident that the
various modifications of this apparatus can be used for distilleries as well as
breweries.
Having now described the nature and particulars of the said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim,-
First, the employment of two streams of water or other liquid in the manner
described for cooling the wort.
Secondly, the employment of an interior tube or tubes of any configuration
or pieces of hollow or solid material to diminish the area of the exterior pipes
or tubes 6.
And, thirdly, the employment of the aforesaid parts of my Invention, either

page_text: separately or conjoined, or any mere modification thereof, such as substituting
Bat or oval pipes or tubes instead of round ones.
In witness whereof, I, the said Francis Gregory, have hereunto set my
band and seal, this Seventeenth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven.
Signed, sealed, and delivered by the
within-named Francis Gregory, in
the presence of
G. SEPTIMUS HUGHES,
Patent Agent,
Manchester.
