PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Raising and Drawing Beer, Wines,
Spirits, and other Liquids by Means of Carbonic Acid or other
Gases.
I ARTHUR GRANVILLE of 26 Budge Row in the City of London, Wool Merchant,
do hereby declare the nature of this invention to be as follows:-
The apparatus hitherto used for drawing liquids have had little guide upon the
pressure or flow of gas whilst passing from the tube containing the gas to the barrells
containing the liquids.
My invention enables me to have entire control of the flow of the gas at high or
low pressure and consequently the flow of the liquids drawn is steady and regular;
the gas is under perfect control by means of this machine which can be attached to
any number of barrels or other vessels at one and the same time and will draw each
barrels contents off in a separate manner as desired.
The gas is admitted from the tube containing it in a compressed form to the
apparatus by a centre tube inserted into the bottom of a vacuum chamber which has
five off branches, one on the upper side to the left to a pressure indicator and one on
the upper side to the right to a blow off or safety valve and one on the upper side in
the centre to a screw with handle attached by means of which the altitude at which it
is desired to draw the beer or other liquid can be regulated, and two more branchos
one on each side from whence the machine is connected by a series of pipes to the
barrels to be emptied, each barrel having an independant turn-off tap.
I use any gas by preference carbonic acid in a compressed form.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Raising and Drawing Beer, Wines,
Spirits, and other Liquids by Means of Carbonic Acid or other
Gases.
1 ARTHUR GRANVILLE of 26 Budge Row, in the City of London, Wool Merchant,
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:-
The apparatus hitherto used for drawing liquids have had little guide upon the
pressure or flow of gas whilst passing from the tube containing the gas to the barrels
containing the liquids. My invention enables me to have entire control of the flow of
the gas at high or low pressure, and consequently the flow of the liquids drawn is
steady and regular, the gas is under perfect control by means of this machine which
can be attached to any number of barrels or other vessels at one and the same time,
and will draw each barrel's contents off in a separate manner as desired.

In the accompanying Drawings:-
Fig. I is a front elevation of the apparatus.
Fig. II is a section of the said apparatus.
A is the body of the apparatus formed in two hollow discs with a rubber
diaphram B between and fixed together by means of bolts R. R. The inlet C is for
the gas from the ordinary carbonic acid gas reservoirs commonly made and filled in
Germany. This gas is under pressure of about six hundred pounds to the square inch
in the resevoir when purchased.

page_text: The spring D is seated on the lower disc under the diaphram B and acted upon
by the disc over the said diaphrain which is raised or lowered by means of a screw
manipulated by the handle G the raising and lowering of which regulates the pressure
of the gas by opening or closing the valve J.
The gas enters from the resevoir by the screw pipe C, and passes through the
valve J and into the chamber F. and out into the barrels of liquids to be drawn off by
the taps I. I. by means of connecting pipes. The pressure of gas thus conducted into
the barrels forces the liquid up the service pipe to the taps from which it is drawn
off in the ordinary way. N. is an ordinary pressure indicator to show the pressure of
gas in passing through the chamber F. The escape valve K is to release the gas if
too much pressure is in the chamber F.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
I. A chamber for the regulation and admission of gas under high or low pressure
to beer or other liquids.
II. An apparatus formed by combined pistons, springs, screw pressure gauge and
valve to safely and effectually lift and force liquids from barrels or other vessels.
III. An apparatus the division in the construction of which renders the passage of
compressed gases free from escape in the transit from the compressor to the fluid to
be acted upon.
