Engineer, do hereby declare the nature of this invention to be as follows:-
My Invention for Improvements in Aerated Water pumps and cylinders relates
to structural improvements, the production of waters more highly charged with
carbonic acid gas at lower bottling pressures, and to providing a ready means of
ascertaining whether the pump is working satisfactorily.
On a suitable bed plate is mounted a crank shaft, which is connected to the
plunger or piston; the latter working in the barrel which is placed on a standard
vertically over same.
The pump is provided with a split suction for gas and water in the usual
manner, but the delivery valve is retained on its seat by a spring exerting a
desired pressure with suitable provision for adjusting same-This delivery valve
may project inside the barrel so that a tapet or cam on the crank shaft may open
same at the proper period, or it may be worked without either and the pressure of.
the water and gas open same-The delivery valve box is connected by a pipe to
the cylinder or main receptacle for the aerated waters-This cylinder which
I prefer to make vertical is constructed in the following manner without the use of
soldering or rubber jointing-I take a straight tube of copper or other suitable
metal and form a thread on the exterior of each end; the upper part of this is then
screwed into a cover having a tapered thread formed on it to receive same; the
lower end is then screwed through a metal flange till it projects slightly beyond
same, and a sheet of tin being laid on the bed plate for carrying the pump the
flange is bolted down; the edge of the copper making a joint on the tin sheet.-
Where the connection tube from the pump enters the cylinder I provide a glass.
vessel closed at it's top, and the aerated water is led into same, at or near the top
in a fine spray; from the bottom of this vessel it is then conducted by means of a
perforated tube to the bottom of the main cylinder so that the discharge of the
pump keeps the aerated water in agitation--I will now explain the action of a
machine made as I have described.
Aerated waters as generally manufactured are made by pumping gas and water
in a suitable pump and then conveying same to a cylinder till sufficient pressure is
obtained to cause the water to absorb the gas when the aerated water produced
is bottled.

page_text: According to my Invention by placing a spring such as I describe on the delivery
valve I create in the pump barrel any pressure I desire, thus forcing the gas into
the water and manufacturing the aerated water before it enters the cylinder-As
aerated waters after they have been made at a high pressure are slow to release the
gas once absorbed they can be bottled at, a much lower pressure, with the advantage
of less breakage of the bottles and danger to the bottler, whilst delivering the
aerated water into an intermediate glass vessel such as I describe enables the
attendant to watch and regulate the quantity of gas and water accurately.
The main cylinder is provided with suitable draw off valves, gauge fittings & in
the usual manner.

Engineer do hereby declare the nature of my invention for IMPROVEMENTS IN
AERATED WATER PUMPS AND CYLINDERS 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 structural improvements, the production of waters more
highly charged with carbonic acid gas at lower bottling pressures, and to providing
a ready means of ascertaining whether the pump is working satisfactorily.-In
order that my Invention may be perfectly understood I will more particularly
describe same, referring to the drawings annexed which shews in Fig. I. a vertical
section in elevation of the complete apparatus.
On a suitable bed plate A is mounted a crank shaft B connected by the rod C to
the cross head D which works in suitable guides in the standard E, attached to this
standard is the pump harrel F, the plunger G of which being secured to the cross
head D; the suction valve I is split in the usual manner for the admission of gas
and water, one of the regulating valves for same being shewn at H-The discharge
valve J communicates with the main cylinder L for the reception of the aerated
water by the connection pipe K which instead of leading direct into same is carried
up at right angles and is provided near its top by a number of small holes―
Encircling this pipe is placed a glass cylinder M which is secured in its place by
the cover m, by means of the nut k screwed on the end of the pipe K and serving
to close same; the water which is discharged as shewn by the arrows at top falls
to the bottom of the glass vessel M and is then conducted by the pipe N which is
closed at its extremity but has a number of perforated holes in it near the bottom
through which the water is discharged, keeping the water in main cylinder L in a
state of agitation; the aerated water is drawn off by the pipe which communicates
with suitable draw off valves at top of cylinder-The cylinder L is constructed in
the following manner, I take a plain tube O of copper or other suitable metal and
form a thread on the outside of each end of same; on the upper end of this I screw
the cover P which has a tapered thread formed on it to receive same, the other end
I screw into a flange p till it projects slightly beyond same, and a sheet of tin
being laid on the raised portion of the bed plate A, the flange p is bolted to same,
the edge of the tube O making the joint on the sheet of tin.
Aerated waters as generally manufactured continuously are made by pumping
gas and water in a suitable pump and then conveying same to a cylinder until a
sufficient pressure is obtained to cause the water to absorb the gas, when the
aerated water produced is bottled.
According to my Invention I place a spring bearing on the delivery valve and
create in the pump barrel a pressure in excess of that in the cylinder equal to
power exerted by the spring and thus cause the water to absorb the gas before it
leaves the pump, and as aerated waters after they have been charged at high
pressures are slow to release the gas once absorbed; they can be bottled at much
lower pressures. The delivery valve J. may be opened by the ordinary pressure of

page_text: the water, or it may project into the barrel as shewn in Fig. 1. and opened by the
plunger G raising same, or it may be prolonged as shewn in Fig. 2. which shews a
section through the delivery valve box, the cover of same being provided with a
gland and stuffing box in which is inserted the spring thrust spindle Q which bears
on the spindle of delivery valve J, through a suitable slot in Q is placed the lever R
pivotted in guide r, above this slot it terminates in a cup to receive the thrust of
spring S; the control of the power exerted by same being obtained by the screw 8.
The thrust of this spring being relieved from the valve at the end of the stroke of
the plunger G by means of a suitable eccentric or cam on crank shaft B through
the tappet T.
.
It will thus be seen that by constructing a cylinder in the way I describe I can
dispense with solder, and reduce the chance of leakage, and in providing a glass
vessel M in which the aerated water is first discharged, the action and throw of the
pump is easily seen. By arranging the delivery valves of pumps as described more
bighly charged waters are produced.
The glass discharge vessel may be applied to existing soda water pumps and the
improved method of charging the waters may also be applied to them...
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
1. The employment of an intermediate vessel between the soda water pump and
the cylinder into which the discharged water and gas is led.
2. The employment of a spring on the delivery valve of a soda water pump in
the manner described in order to create an excess pressure in the pump barrel, and
the methods for relieving same.
3. The construction of a cylinder by screwing the ends in the manner herein
described.
4. The application of an intermediate glass vessel, the employment of a spring
on the delivery valve, and the construction of an improved soda water pump and
cylinder as herein described and shewn.
