PROVISIONAL SPECIFICATION.
Improvements in Appliances for Carbonating Drinks..
THOMAS BARKER Engineer 92 Orlando Street Bolton in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
The object of my invention is to carbonate drinks with liquified or compressed
carbonic acid gas in quantities of less than one quart to accomplish this I propose
to apply to the ordinary cylinders (containing liquified or compressed carbonic acid
gas) a reducing vale for reducing the pressure to any required pressure and after
the gas has been reduced it passes from the regulators or reducing valve through
a flexible tube and suitable connections into a metal cylinder or bottle with bell
mouth or funnel top and with a suitable stopper or valve and containing the liquid
or drink to be carbonated the said cylinder and stopper or valve to be made in
such a manner as to imitate or be equivalent in action to the opening of an ordinary
stoppered mineral water bottle, that is to say, the pressure of the gas in the bottle
to be suddenly liberated and let out into the atmosphere before the drink is drawn
off or poured out into the drinking glass or vessel by this arrangement I am enabled
to retain the full pungency of drinks carbonated in small quantities which has
hitherto not been accomplished.
The operation is as follows.
The drink or liquid is first put into the bottle which I propose to make to hold
about one fourth of a quart, or sufficient to fill an ordinary drinking glass or vessel,
the stopper or valve is then closed and the gas turned on until the gas reaches the
required pressure which will be shown on a pressure guage, fixed to the apparatus
the reducing valve having been previously adjusted to shut off the gas at the
required pressure, the supply of gas is then shut off, and the bottle is taken in the
hand and shaken until the pressure shown on the guage ceases to go down, which
will prove that the drink is thoroughly carbonated the stopper or valve is then
suddenly opened, and the drink poured out into the drinking vessel.
The bottle may be made from glass earthenware or metal or a combination of the
same with suitable fittings.
I propose to make the reducing valve as follows.
In a suitable metal casing with inlet and outlet passages and an outlet for the
pressure guage and an arrangement of a diaphragm and spring so arranged that
the pressure entering the chamber will force back the diaphragm and spring and
they in turn will force a knuckle or ball jointed connecting rod or deflecting valve
spindle hinged near the centre from the deflected position to pearly a straight one
thus elongating and closing up the gas inlet.

Engineer 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 :-
Fig. 1. is a section of a reducing valve.
Fig. 2. is an external view of a reducing valve, with safety valve attached which
is shown in section.
Fig. 3. are ball ended and knuckle jointed connecting rods or deflecting valve
spindles, for reducing valve.
Fig. 4. is a vertical section of a metal cylinder or bottle.
Figs. 5 & 7 are baffles or saturaters for inside of bottle Fig. 4.
Fig. 6. is a front view of the complete apparatus with part of the top of casing
and the door cut away, as shown at g 1 and
92.
a, Fig. 1. is the metal body or casing of reducing valve. 1, is a chamber.
a 2, and a 3, are ball ended and knuckle jointed connecting rods or deflecting valve
spindles. a 4, is a connecting rod or link for connecting a 2, a 3, and a 7, by the
joints a 5, and a 6, see also Fig. 3. a 7, Fig. 1. is a round collar fixed or cast to
spindle d3, and carries the hinged joint a 6, and rod or link a 4, which carries
the knuckle joint a 5. b, is a valve block which is made to move freely in the
body a, and is recessed at one end to receive ball end of rod a 3, and the other end
is recessed to receive valve 61, which may be of metal, vulcanite, or any other
suitable material. 64, are grooves cut in the valve block b, to form passages for
the entrance of gas into the chamber a 1.
62, is the gas inlet passage.
33, is a nozzel formed on casing a, for placing leather washer or other material
on to make a pressure tight joint on the cylinder, " containing compressed carbonic
acid gas" by the coupling nut 6, see Fig. 6.
c, Fig. 1, is an abutment block screwed into the body a, and is recessed at one
end to receive the ball end of rod a 2, the other end is also recessed to receive
point of cone formed on the lock nut c 1. c2 and c 4 are passages for the gas to
the pressure gauge which is screwed into c 5. d, is a cap or lid for casing a. d 1, is a
diapragm made of skin or other none porous and flexible material. 8, is a disc
or plate fitting loosely on spindle d 3, and is at liberty to move freely in the
cylinderical chamber J, between d 8, and a 7, is placed the aforesaid skin or diapragm
and is held fast by the nut d 2, the outer surface of the diaphragm is placed
between flanges of the body a, and cap d, and held by set screws J 1. d6, is a
flanged screw for pressing on the springs d 4, and d 5, and is regulated to suit the
pressure to which it is intended to reduce to. d 6, is bored out to receive the
spindle d 3, which is at liberty to slide freely in same. d7, is a lock nut for locking
the screw d6. d 9, is a safety hole to let out any escape or leakage of gas. The
operation of this reducing valve is as follows,-Say d 6, has been set to reduce
pressure from 700 lbs. to 100 lbs. per square inch the gas at 700 lbs. per square
inch enters the passage 62, and through passages 64, into a 1, and as the pressure
increases in the chamber 1, it lifts the disc or collar a 7, this in turn lifts the
knuckle joint a 5, thus deflecting a 2, and a 3, from their bent positions to nearer
a straight line thus elongating the two rods a 2, and a 3, in such a manner as to
close the valve b1, when the pressure in chamber a 1, reaches 100 lbs. per square
inch or any other pressure the regulator may be set for.
By this arrangement I get great flexibility with the springs and a great surplus of
power over the pressure entering at 62, "on account of the greater area of the

page_text: iaphragm, and the block or collar a 7, than is in the opening 62, also the greater
e, Fig. 2. is
ower gained by the deflecting and elongating of rods a 2, and a 3.
be body of a safety valve, shown part in section and screwed or cast to the body
of regulator, and an outlet passage from chamber a 1. e 1, is a valve block which
s at liberty to slide freely in cylinderical chamber e 6. e2, is a loose valve made
of vulcanite or any suitable material. e 3, is a spring, e 4, is a screw for pressing
on the spring and is regulated according to the pressure required.
f, Fig. 4, is a metal cylinder or bottle shown in section. f1, is a rubber or other
soft substance to make a pressure tight joint. 2, is a funnel or bell mouth for
pouring the water or liquid to be carbonated into the bottle. f3, is a bracket fo:
carring the valve spindle f4, which is at liberty to slide freely up and down. f5, is a
button screwed or fixed on the top end of valve spindle f4, and has on its under
side a recess cut in, forming a flange or lip f6, for the spring latch or catch ƒ7, to
latch on when the button f5, is pressed down. f8, is a rubber or leather washer.
f9, is a flanged nut for fastening the rubber or leather washer to the valve
spindle f4. 10, is a lock nut. f11, is a spring for closing the valve f8 and ƒ9.
12, is a baffle plate or saturator for agitating and mixing the gas with the liquid
"to be carbonated," when the bottle is shaken to and fro by the hand. m, Fig. 1
is a coupling nut. m 3, is a rubber tube for connecting the bottle to the reducing
valve. m2 and m 4, are metal ripples. Fig. 5, is another view of baffle or
saturator plate which may be varied in shape, also in some cases I may use several
may use a spiral one, with plain or
of them in a bottle, and in other cases
serrated edges, and reaching nearly from top to bottom of the bottle, sec Fig. 7.
g Fig. 6, is a wood cabinet, the wood or marble top or lid for the cabinet is cut
in two across the centre, shown in section at g 1, the top part of the door is cut
away at 92, so as to show the cylinder h, which contains compressed or liquified
carbonic acid gas. 1, are clips for holding cylinder h, in position. 93, are glass
decanters or bottles containing flavouring essences. 94, are balconies or shelves
for holding the glass bottles, the said shelves can be increased in number according
to the number of, and various kinds of essences used. 2, is a metal cover which
passes freely through the top of the cabinet, and rests upon the main valve h 3, of
cylinder. h4, is the handle for main valve h 3. 5, is a pressure gauge. a, is the
aforenamed reducing valve. 6, is a coupling nut for coupling the reducing valve
to the cylinder valve h3. m, is a coupling nut for coupling the rubber tube to
m3, is a rubber or flexable tube. f, is a metal
regulator or reducing valve."
bottle. 2, is a funnel for pouring the liquid into the bottle. f5, is a button for
opening the outlet of bottle. f7, spring latch for holding the outlet valve open.
The bottle f, may be made of glass or any other suitable material. The drinks
First the button /5, is pressed down
are carbonated in the following manner.
until it is held by the spring f7, then the liquid or water is then poured into the
funnel 2, then the spring f7, is pressed inwards which causes the valve or stopper
to close, then turn on the gas at h4, for a second or so, or until the required pressure
is registered on pressure gauge h 5, then close the main valve at h4, take the
bottle f, in the hand and shake it for a second or two, or until the pressure on the
gauge ceases to go downwards, then press or knock down the button fa, which will
suddenly liberate the surplus gas and pressure in the bottle, then pour out the
drink into a drinking vessel. It is not absolutely necessary to turn off the gas at
the main valve before shaking the bottle.
Having now particularly described and ascertained the nature of my said inven-
0 tion, and in. what manner the same is to be performed, I declare that what 1
