SAMUEL MASON of Birmingham in the County of Warwick Manufacturer
IMPROVEMENTS IN COMPRESSED AIR MACHINES FOR AERATING AND RAISING BEER
AND OTHER FLUIDS.
•
This Invention consists of a receiver to hold water and air at the bottom of the
receiver are two taps one for the supply of water and the other to withdraw it, on
the top of the receiver is an Index and a bracket carrying two taps one is in
connection by means of a tube with the cask to supply air and the other with the
air supply to the receiver, a guage is fitted at the side of the receiver to indicate
the height of water.
The operation is as follows: to get the air pressure into the cask turn on the
water supply tap until sufficient pressure is indicated on the index then turn on
the tap of the tube supplying air to the cask when the finger of the index will
return and when it is at rest there is sufficient air in the cask then turn off the
air supply tap to the cask and the pressure can be renewed if necessary.
When the water guage at the side shews that the air receiver is empty open the
tap of the pipe supplying air to the receiver and turn on the waste water tap and
let the water run off.
"
Or the same effect may be gained by providing a weight working from the top
of the receiver into a body of water and thus by displacement of the water
compressing the air.

SAMUEL MASON of Birmingham in the County of Warwick Manufacturer
"IMPROVEMENTS IN COMPRESSED AIR MACHINES FOR AERATING AND RAISING BEER
AND OTHER. FLUIDS,”
"
This Invention consists of a receiver to hold water and air, at the bottom of the
receiver are two taps one for the supply of water and the other to withdraw it, on
the top of the receiver is an Index and a bracket carrying two taps, one is in
connection by means of a tube with the cask to supply air thereto and the other
is the air supply to the receiver, a guage is fitted at the side of the receiver to
indicate the height of water.
The operation is as follows to get the air pressure into the cask turn on the
water supply tap until sufficient pressure is indicated on the Index then turn on
the tap of the tube supplying air to the cask, when the finger of the Index will
return and when it is at rest there is sufficient air in the cask then turn off the
air supply tap to the cask, and the pressure can be renewed if necessary.
When the water guage at the side shews that the air receiver is empty open the
tap of the pipe supplying air to the receiver and turn on the waste water tap and
let the water run off.
Or the same effect may be gained by providing a weight working from the top
of the receiver into a body of water and thus by resistance of the water compressing
the air. No beer pump or air pump is required for either form of machine.
Fig: 1 is a view of my Improved Receiver to hold water and air, at the bottom of
this Receiver are two taps A. and B. the tap A is for the supply of water and the
tap B is the waste for withdrawing the water when requisite.
On the top of the receiver is an index C. and a bracket D. carrying two
taps E and F the tap E is for the air supply to the receiver and the tap F is in
connection by means of a tube with the cask or casks for supplying the compressed
air thereto.
G is a guage fitted at the side of the receiver to indicate the height of water
therein. In connection with the water supply tap A I use an upright pipe H
fitted with a perforated discharge pipe I so that the water is supplied into the
receiver in the form of spray and passes through and purifies the air within the
receiver,
K is a ball valve for preventing the escape of water into the compressed air
pipe F should it rise in the receiver above the regulated height.
The operation is as follows, to get the air pressure into the cask containing the
beer or other fluid the empty receiver having been filled with air from the tap E.
and that turned off, turn on the water supply tap A until sufficient_pressure is
indicated on the index C. when the tap A must be shut off and the tap F. supplying
air to the cask turned on. When the finger of the index C. will return and is at
rest there is sufficient air supplied to the cask then turn off the compressed air
supply pipe F. When the water guage G upon the side of the air receiver being
full of water shows that the receiver is empty the tap E must be opened to refill
the receiver with air and the waste water tap B must be turned on to let the
water run off.
By another arrangement as shewn in Fig. 2 the same effect may be gained by
forming the receiver in two parts L and M the upper portion L sliding up and
down within or over the lower part M and being fitted with flanges or guides N.

page_text: The two portions L and M. are made air tight with each other and thus
constitute a telescopic receiver capable of expansion or contraction vertically the
upper part L may be acted upon at the point P or where convenient by means of
a screw, lever weight, or counter balance weights for the purpose of depressing or
lowering the part L.
R is the air supply tap through which the air is admitted into the receiver, S is
a tap which may be used either to supply water into the lower portion M of the
receiver or to withdraw it therefrom. T represents the height of water in the
receiver when ready for work. V. is the tap communicating with the pipe V₁ for
supplying the compressed air to the cask, or the compressed air pipe or tap may be
arranged upon the part L, if preferred.
In operating the receiver the upper part L is depressed by means of the screw or
weight and the air meeting with the resistance of the water in the lower part M
will become compressed until a sufficient pressure is indicated upon the index not
shewn-and by turning on the tap V such compressed air will be supplied to the
cask or casks in suitable quantity and pressure and which I purpose regulating.
When it is necessary to gain a fresh supply of air into the receiver the tap R
must be turned on and the upper part L raised to its original position. In
connection with either form of my Improved receiver I sometimes prefer to employ
an intermediate receptacle into which is admitted the compressed air from the
receiver and the beer or other liquid from the main cask in suitably regulated
quantities and from this intermediate receiver'the aerated fluid is raised for use.
By my Improvements no beer pump is required for either form of machine.
Having thus described the object and nature of my said Invention and the
manner in which the same is to be carried into effect I claim without limiting
myself to these precise details.
Firstly The Improvements in machines for aerating and raising beer or other
fluids by forming a receiver to contain water and air in contact with each other,
thus obtaining the desired pressure as herein described and shewn in Fig: 1.
Secondly. I claim the construction and arrangement of such machines in two
parts working telescopically as represented in Fig―2.
In witness whereof I the said Samuel Mason have hereunto set my hand
and seal this seventh day of December in the year of our Lord. One
thousand eight hundred and eighty two.
