IMPROVE- MENTS IN BEER ENGINES
Year: 1859

page_text: LETTERS PATENT to James Grimes, of 6, Osborn Street, Whitechapel,
Pewterer and Beer Engine Manufacturer, for the Invention of "IMPROVE-
MENTS IN BEER ENGINES."
Sealed the 6th May 1859, and dated the 11th February 1859.
PROVISIONAL SPECIFICATION left by the said James Grimes at the
Office of the Commissioners of Patents, with his Petition, on the 11th
February 1859.
I, JAMES GRIMES, of 6, Osborn Street, Whitechapel, Pewterer and Beer
Engine Manufacturer, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN BEER ENGINES" to be as follows:-
This Invention lias for its object improvements in beer engines, and consists
in applying to such engines coolers through which the beer or liquid is caused
to pass after it leaves the pump cylinder, and before it passes to the cock or spout
by which it is drawn off. The cooler is so formed as to fit against the front
of the case of the engine; it contains a cylinder or a vessel of other convenient
form, which is connected by a pipe to the engine after the cock or spout by
which the liquid is ordinarily drawn off has been removed; this cylinder or
vessel is contained in a cistern in which ice may be placed, and, it is furnished
with a pipe or spout by which the cool liquid passes to be drawn off. When
the engine is in use, each time that the lever handle is moved, a measure of
liquid is forced into the cooling cylinder or vessel, and it displaces a similar

page_text: quantity previously raised, and which has remained a sufficient time in the
cooler to become chilled to the required degree. In addition to the cooling
cylinder or vessel for containing the liquid raised by the engine, another vessel
is contained within or placed in contact with the ice cistern, and in this vessel
water may be cooled. In place of causing the liquid to pass into a cooling
cylinder or vessel after it has been raised by the engine, the liquid may, if it
be preferred, be caused to pass through a cylinder or vessel contained in an ice
cistern before it enters the pump cylinder. In either case, if only a slight
degree of cooling be required, the pipe through which the liquid passes may
itself form a cooling vessel of sufficient size, and it will then be necessary only
to surround this pipe with an ice cistern.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Grimes in the Great Seal Patent Office on the
11th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
GRIMES, of 6, Osborn Street, Whitechapel, Pewterer and Beer Engine Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by İler Letters
Patent, bearing date the Eleventh day of February, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Grimes, Her special licence that I, the said James
Grimes, my executors, administrators, and assigns, or such others as
I, the said James Grimes, 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 BEER ENGINES," upon the condition (amongst others)
that I, the said James Grimes, 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.

page_text: NOW KNOW YE, that I, the said James Grimes, do hereby declare
the nature of the 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 thereof, that is to say :-
This Invention has for its object improvements in beer engines, and consists
in applying to such engines coolers through which the beer or liquid is caused
to pass after it leaves the pump cylinder, and before it passes to the cock or
spout by which it is drawn off. The cooler is so formed as to fit against the
front of the case of the engine; it contains a cylinder or a vessel of other
convenient form, which is connected by a pipe to the engine, after the cock or
spout by which the liquid is ordinarily drawn off has been removed; this
cylinder or vessel is contained in a cistern in which ice may be placed, and it
is furnished with a pipe or spout by which the cooled liquid passes to be drawn
off. When the engine is in use, each time that the lever handle is moved, a
measure of liquid is forced into the cooling cylinder or vessel, and it displaces
a similar quantity previously raised, and which has remained a sufficient time
in the cooler to become chilled to the required degree. In addition to the
cooling cylinder or vessel for containing the liquid raised by the engine,
another vessel is contained within or placed in contact with the ice cistern,
and in this vessel water inay be cooled. In place of causing the liquid to pass
into a cooling cylinder or vessel after it has been raised by the engine, the
liquid may, if it be preferred, be caused to pass through a cylinder or vessel
contained in ati ice cistern before it enters the pump cylinder. In either case,
if only a slight degree of cooling be required, the pipe through which the
liquid passes may itself form a cooling vessel of sufficient size, and it will
then be necessary only to surround this pipe with an ice cistern.
And in order that my Invention may be most fully understood and readily
put into practice, I will now proceed to describe the accompanying Drawing.
Figure 1, shows a transverse vertical section of a beer engine, having my
Invention applied. a is the pump cylinder of an ordinary beer engine, with a
pipe a passing therefrom down to the cask in the cellar, from which beer or
other liquor has to be pumped; a² is another pipe passing from the upper part
of the pump cylinder a to the cylinder or other cooling vessel b, into which the
beer or other liquid is pumped, in order to be cooled; for this purpose the
vessel is enclosed within an outer case c, c, lined with zinc, lead, pewter, or
other suitable material, and the intervening space between the exterior of the
vessel b, and the interior of the vessel c is filled with ice, so as entirely to
surround the cylinder or other vessel b, containing the liquid pumped up by
the pump a.
The ice in the case or chamber c rests on a metal bottom c',

page_text: beneath which is a receptacle d for water, which may be placed therein at the
spout to be cooled, and it may be drawn off as required at the cock *.
The beer or other liquid after having been in the vessel 6 long enough to be
cooled, is displaced by the further action of the pump a, and the beer or other
liquid is forced up the pipe from the upper part of the cooling cylinder or
vessel 6 to the spout into the measure or receiver, so that when the bandle f
is drawn forward, a measure of the cooled beer or other liquid will be drawn
off at the spout c; g is a sink, into which any of the spilt liquid is received,
and g' is a pipe for conveying the same away into the waste butt.
Figure 2, shows the cooling apparatus detached from the beer engine,
leaving the engine to be worked as a common beer engine, during such time
as the cooling of the liquid is undesirable. The spont e would then be un-
screwed from its place and screwed into the opening at e¹ instead, the cooling
apparatus being put away until change of temperature again requires it to be
used. The cooling vessel may be either cylindrical or of a square, oblong, or
other convenient shape, and when several pumps are employed, it may be
either formed as one vessel divided into chambers, or there may be a vessel to
each pump cylinder. With a view to prevent the inconvenience that might
arise from the increased space occupied when the cooler is in use, being still
necessary when the cooler is no longer required, the shelf is hinged at /' to
the vessel c', and flaps i turning on centres 2, i, carried by the wood framing
are employed to support it, so that when the cooler is removed, by unscrewing
the union joints, the sink may be slid back into the place that was before
occupied by the cooler, and it will then be in the proper position to receive
the drippings from the spout e, in its altered position at e¹; j is a screw
plug by which the water produced by the melting of the ice.may be run off.
I would remark that although the arrangement shown in the Drawing is that
which I prefer, the parts thereof may be considerably modified in form without
departing from my Invention, and it will readily be seen that a similar
apparatus may be employed to cool the beer or other liquid before it enters
the pump cylinder, if it is preferred..
In witness whereof, I, the said James Grimes, have hereunto set my
band and seal, this Eleventh day of August, in the year of our Lord
One thousand eight hundred and fifty-nine.
