PROVISIONAL SPECIFICATION.
An Improved Beer-raising Apparatus.
I, FREDERICK WALTER, of 47 Hassett Road, Homerton, in the County of
Middlesex, Mechanical Draughtsman, do hereby declare the nature of this invention.
to be as follows:-
My invention relates to apparatus used for the raising of beer, such as from a cellar
to the bar, by means of carbonic acid gas.
My invention consists in using carbonic acid gas stored at a very high pressure say
2000 pounds on the square inch, and allowing such gas to pass through a reducing
valve of any approved form so that the said gas becomes reduced in pressure from the
2000 pounds on the square inch to the necessary pressure for raising the beer namely
from 15 to 20 pounds on the square inch as the case may be. The pipe from the
reducing valve is led into the top of the barrel so that upon the tap being opened in
the beer delivery pipe, the pressure derived from the stored carbonic acid gas forces
the beer through the said delivery pipe.
It will be readily understood that it is quite impracticable to use the high pressure
gas in direct communication with the barrel of beer, as the barrel would not stand so
high a pressure.
The advantage of using a reducing valve, instead of an intermediate chamber as has
been done before, is that in the case of the intermediate chamber, which for example
may be filled in the morning with the gas at 20 pounds pressure on the square inch
from the high pressure reservoir, towards the end of the day the pressure will have
become reduced in the proportion of the beer used and may have dropped down to
10 pounds pressure on the square inch, thereby only having half the raising effect as
when the intermediate vessel was fully charged; whereas where the reducing valve is
used it so regulates the supply of gas to the barrel of beer from the high pressure
charge that the said supply of gas is always given out at a constant pressure at which
pressure the valve may bo set. From the time that the pressure in the high pressure
storing cylinder is at 2000 pounds on the square inch till it has run down to the beer
raising pressure, the pressure of the gas after passing the reducing valve is entirely
constant.

COMPLETE SPECIFICATION.
An Improved Beer-raising Apparatus.
I, FREDERICK WALTER, of 47. Hassett Road, Homerton, in the County of
Middlesex, Mechanical Draughtsman, 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 for the raising of beer, such as from a
cellar to a bar or bars by means of compressed carbonic acid gas or other equivalent
compressed gas or fluid.
My invention consists in using carbonic acid gas or other equivalent compressed
gas stored in flasks at a very high pressure, say 1,000 lbs. on the square inch as they
are nowimported.
In allowing such gas to pass through a reducing valve or valves of any approved

page_text: form, the gas becomes reduced in pressure from the 1,000 lbs. on the square inch to
the necessary pressure for raising the beer from the level of the cellar to the
various heights of the different Hoors to which it may be desired to deliver the
heer.
After the gas pressure has passed its respective reducing valve and a controlling
tap, it is led into the top of any barrel containing beer so that upon the tap in the
gas pipe and that in the beer delivery pipe being opened, the pressure derived from
the stored carbonic acid gas forces out the beer or other liquid through the said
delivery pipe. The gas supply tap is left permanently open and the delivery of the
beer is determined by the tap in the beer delivery pipe.
It will be readily understood that it is quite impracticable to use the high pressure
gas in direct communication with a barrel of beer, as the barrel would not stand so
high a pressure.
Different degrees of pressure should be used for the various floors of different
height, in order that the gas pressure should be exactly regulated so as to be sufficient
to discharge at any required height and without useless excess of pressure, which
would only cause the gas to be used to waste, and cause the unnecessary frothing and
scattering of the beer when the pressure is excessive.
The advantages of using a reducing valve for each level or floor of discharge,
instead of using an intermediate chamber as has been done before, is :-That with the
automatic reducing valves the pressure when once set for the required height is auto.
matically maintained at the required pressure, whilst an intermediate chamber must
be recharged from time to time and the pressure will naturally have become much
reduced at the period before recharging. When fitted with reducing valve from the
time of initial pressure in the high-pressure storage flask or flasks viz. 1000 lbs. per
square inch, till it has run out of the minimum pressure of lift, the pressure of the
gas operating on the beer will be maintained entirely constant.
To carry my invention into effect I prefer to use two or more flasks, rather than a
single flask, each connected by suitable pipes provided with cocks to the main
reducing valve, causing a first reduction of pressure from all the flasks combined
providing the maximum pressure required for lifting to the highest bar or floor of
discharge. To prevent the valves on the flask from being tampered with, the valves
may be covered by a locking cover.
Where the beer is to be delivered to a floor or bar lower than that already referred
to, earry a second supply main from the main gas supply and place in the second
main a further reducing valve so that the pressure in this supply shall correspond with
only a suitable margin to the pressure required for the lower lift, and thus in the same
manner attach to the main supply from the first reducing valve a series of subsidiary
gas mains each controlled by its own respective reducing valve, to give a constant
required pressure specifically regulated for each floor to effect the required lift.
The employment of more flasks than one to provide the store of high pressure
gas is useful, since it permits by the successive use of the flasks the initial pressure
to be maintained more regularly by the combination of the pressures from a partly
empty and a full flask than would be the case when one flask only used.
DESCRIPTION OF DRAWINGS.
The illustration herewith shows a perspective elevation of the general arrangements
of my apparatus for raising beers by various regulated pressure mains to any series
of desired heads, that is to various Hoors or bars. A. A. A. are three storago flasks
containing carbonic acid gas, or other gaseous fluid at a high pressure they are
provided with the usual screw down valves a a a connected by pipes, each provided
with a stop cock B to the common main passing into the reducing valve C provided
with a pressure gauge e and screw-down valves b. b.
By these means the high pressure gas is passed at any desired reduction of
pressure by means of the reducing valve C. into the first main D.
From this main are taken a series of subsidiary gas pressure mains E' E* and E'

page_text: which are each provided with independent reducing valves F1 F2 and F3 by means
of which these various subsidiary mains may be supplied with various further
reductions of pressure to exactly suit the height of floor, or bar to which it is required
to lift the Beer.
This power of independent adjustment of pressure for each floor is of importance as
the Beer should be delivered with only a minimum of pressure above that required to
make the actual lift.
To avoid waste by over frothing, or over velocity of discharge, branch pipes G. G. G.
are run from each of these subsidiary mains to serve for individual casks H. H. and
are provided with stop cocks g. g. g. by which the various Casks can be connected, or
disconnected as desired.
Having now particularly described and ascertained the nature of my said Inven-
tion and the manner in which the same is to be performed I declare that what I
claim is
Firstly. An improved apparatus for raising Beer by the pressure of high pressure
stored carbonic acid gas or other equivalent compressed gas distributed in mains,
each controlled by an automatic reducing valve to certain Beer Barrels for the
delivery of their contents at a suitable determined pressure, according to the height of
one or many floors on which the delivery of the Beer is required.
Secondly. The specific combination of apparatus for raising Beer to various heights
by the pressure of carbonic acid or other equivalent compressed gas, substantially as
herein described.
