Improvements in Apparatus for Carbonating Liquids.
I, CHARLES BRIGHT VAN HORN, of 87–99, Fort Street, East, in the City of
Detroit, County of Wayne, and State of Michigan, United States of America,
Gentleman, 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 slatement:-
-
This invention relates to certain new and useful improvements in apparatus
for carbonating liquids.
The primary object of the invention is to regulate the supply of liquid to the
apparatus by the amount drawn off.
A further object of my invention is to carbonate liquids under a constant gas
pressure with the inlet and outlet controlled by the liquid in the apparatus, the
liquid being forced into the apparatus either by pump or air pressure and forced
from the apparatus by the constant gas pressure in the apparatus which serves
both to thoroughly impregnate the liquid with gas and to force the liquid from
the apparatus into any suitable receptacle under any suitable counter pressure.
Another object of the invention is to maintain a constant gas pressure on the
liquid to be carbonated, in inverse ratio to the specific gravity of the liquid.
The constant pressure is maintained by securing a reducer in the gas supply pipe.
A still further object of my invention is to construct an apparatus for carbonat-
ing liquids of all kinds that will be purely automatic in every particular.
In describing the invention in detail, reference is had to the accompanying
drawings forming a part of this specification, wherein like figures of reference
indicate similar parts throughout the several views in which:-

Fig. 2 is an end elevation of the same.

top plan view.
Fig. 5 is a sectional view of an air operated valve located in the inlet pipe.
Fig. 6 is a sectional view of the valve controlling the admission of the air to
he air operated valve.
Referring to the drawings by reference numerals, 1 designates a horizontal
ylinder forming an infusion chamber, and 2 a vertical cylinder forming a car-
bonated liquid receptacle.
The infusion chamber 1 is mounted upon a suitable hollow support 3, near one
nd thereof, and secured to the opposite end and on the underneath side thereof
8 a hollow casting 4, which is mounted on a suitable support 5, said hollow cast-
ng communicating with the infusion chamber 1.
Secured to the hollow casting 4, and communicating therewith is a liquid
nlet pipe 6, in which is arranged the air operated valve 7. Secured to the top
of the infusion chamber, and communicating therewith is a hollow casting 8
which receives the gas supply pipe 9. Arranged in the top of the casting 8 is a
elief valve 10, of any suitable construction, and secured to the casting 8, and on
..

page_text: the opposite side thereof from the gas supply pipe 9, is a pipe 11, which leads
to the top of the sight glass 12, and pipe 15 connects the lower end of the sight
glass 12 with the hollow casting 4. Secured to the pipe 11, is a pressure gage 14,
of any suitable construction.
Journaled in the ends of the infusion chamber 1, is a shaft 16, having con-
nected to one end thereof, a driving wheel 17. Mounted on this shaft within
the infusion chamber 1, are paddles or blades 18, which are adapted to agitate the
liquid, so the same will become thoroughly impregnated with gas. Said infusion
chamber is also provided with a hand hole 19.
Mounted on the support 20, is the carbonated liquid receptacle 2, between
which and the support 20 is a hollow casting 21, communicating with said recep-
tacle; this hollow casting 21 receives the liquid discharge pipe 22, in which is
secured the sight glass 23. Connecting the liquid discharge pipe 22 and pipe 15
communicating with the lower end of the sight glass 12, is a pipe 24, which is
adapted to drain the liquid from the infusion chamber 1. Arranged on one sido
of the carbonated liquid receptacle 2, and connected therewith, is a sight glass 25.
Mounted on the shaft 25, is a lever 26, carrying on its one end a float 27. Ful-
erumed to this lever 26, is a connecting rod 28, the lower end of which is pivot-
ally secured to a lever 29, and pivotally secured to the lever 29 about midway
its ends, is a connecting rod 30, to the lower end of which is secured the balanced
valve 31, operating in the valve seat 32, this balanced valve and valve seat being
located inside the hollow casting 21.
Secured to the end of the shaft 25, projecting through the head of the carbo-
nated liquid receptacle 2, is an arm 33, the object of which will be hereinafter
more fully described.
Arranged above the arm 33, and secured to the receptacle 2, is a valve secured
in the air supply pipe 31, said valve admitting air to the air operated valve 7,
to operate the same.
Arranged in the pipe 34, is a chambor 35, which is provided with a valve
seat 36. Projecting through the extension 37, of the pipe 34, is a valve stem 38,
on the upper end of which is secured a valve 39, adapted to engage the valve
sent 36 (see Fig. 6). Secured to the valve chamber 35, is a pipe 34 leading
to the air supply (not shown).
Secured to the pipe 34, is a vertical pipe 40, in the upper end of which
is secured an escape valve 41. The opposite end of said pipe 40 is connected to
a cylinder 42, in which the piston head 43 operates. Secured to said piston
head 43, and passing through a stuffing box 44, of any suitable construction, is
a valve stem 45, carrying on its opposite end a balanced valve 46, of the samo
form and construction as the valve 31. Said infusion chamber and carbonated
liquid receptacle are secured together as shown at 47, forming a passageway 48.
The receptacle 2 is arranged on a lower level than chamber 1, as shown.
This passage is located near one side of the infusion chamber and near the
opposite end from that in which the liquid enters. The object in locating the
passage as shown, is to retain the liquid in the infusion chamber a sufficient
length of time so that it will become thoroughly impregnated with gas before it
passes into the carbonated liquid receptacle. By arranging the receptacle 2 on a
lower level than chamber 1, I establish a level of the liquid in the carbonated
liquid receptacle which is below that established in the infusion chamber. Were
the carbonated liquid receptacle placed on the same level with the infusion
chamber, the carbonated liquid in the liquid receptacle would overflow into the
infusion chamber and destroy the perfect operation of the carbonator.
The operation is as follows:-
The pipe 22 is connected to a storage tank containing the desired counter
pressure, the gas is admitted to the infusion chamber 1 through the gas supply
pipe 9, until a predetermined pressure is obtained, which pressure is maintained
during the process of carbonating by securing in the gas supply pipe a reducing
valve of any of the well known constructions. The liquid is then admitted to

page_text: the infusion chamber 1, through the pipe 6, and the liquid continues to rise in
the chamber until it reaches the point of overflow of passage 48, when it flows
into the carbonated liquid receptacle 2. As the liquid accumulates in the recep-
tacle 2, the float 27 is raised. and through the intermediate mechanism the
balanced valve 31 is opened, allowing the carbonated liquid to discharge through
pipe 22 as fast as it enters the infusion chamber.
Should the influx of liquid be greater than the quantity drawn off, the surplus
accumulates in the receptacle raising the float 27, until the arm 33 comes in con-
tact with the rod 38, when the valve 39 is raised from the valve seat 36, thereby
allowing the air to pass through the pipes 341, 34 and 40, and act upon tho
piston head 43, forcing the piston od 45, and balanced valve 46, downward and
automatically shutting off the flow of liquid to the infusion chamber 1.
When the accumulated liquid in the carbonated receptacle has been reduced,
the float 27 descends carrying the arm 33 out of engagement with the rod 38
of the valve 36. The pressure of the air against the top of the valve and spring
(shown in Fig. 1) closes the valve 36, cutting off the supply of air to the air-
operated valve, allowing the tension of spring 50 to open the valve 46.
The supply of liquid to the infusion chamber is automatically regulated by the
discharge of the liquid from the carbonated liquid receptacle. When the liquid
is admitted to the apparatus, no further attention is required.
It will be noted that any liquid can be carbonated in the apparatus above
described, the only change required being the regulating of the gas pressure in
the infusion chamber, in inverse proportion to the specific gravity of the liquid
to be carbonated.
