New or Improved Aerating Apparatus.
We, EMIL KOENIG, of Long Island City, Borough of Queens, and State of New
York, United States of America, Manufacturer, and MITCHELL LOUIS ERLANGER,
of the City of New York, Borough of Manhattan, and State of New York, United
States of America, Attorney at Law, 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:-
This invention relates particularly to apparatus for aerating beverages.
The present invention relates generally to apparatus for acrating beverages and
consists of means by which the feed of the liquid and the aerating of the beverage
or the absorption of the gas by the liquid is effected so that the beverage can be
drawn from the apparatus thoroughly saturated with the gas.
In order that the invention may be more fully understood, we have illustrated
in the accompanying drawings in sectional elevation a practical embodiment
thereof, it being understood, however, that the purposes, arrangement and details
of construction shown may obviously be changed to suit the requirement of the
particular use to which the apparatus may be put. Figure 1 is a sectional eleva-
tion, and Figures 2 and 3 are respectively transverse and horizontal sections of
the valve chambers.
Referring thereto, the apparatus consists of a closed tank or chamber C, capable
of containing the necessary quantity of aerated liquid or beverage. With this
tank is associated in any convenient position, as shown, supported on the top
closing plate of the chamber, a pair of cylinders h, i, having pistons h,, con-
nected together by a single piston rod k. Associated with each of these cylinders
is a valve chamber m, n, each having a valve m, n, the valves being connected
together by a single valve steno. These valves are of D-shape, and the pressure on
them is balanced more or less by the strips m2, n², bearing against the underside of
the valve-chest cover, as shewn in Figures 1 and 2, and each valve controls admis-
sion of fluid to both sides of the piston of each cylinder and also to an exhaust
or outlet as is common in such valves. With the piston rod k, and the valve
stem o, is combined a rocking lever p, with collars and q' or other projections
on the rod and stem, so that when the pistons move and one of the collars of
the rod strikes the rocking lever it will act against one of the collars of the
valve stem o to shift the valves. The valve chamber n, (see Figures 1 and 3)
is in communication with a water supply pipe A, in which may be interposed any
suitable filter or other water purifying device F, so that the liquid supplied to the
chamber may be purified in any proper manner; and the exhaust passage from the
cylinder, which passage is controlled by the valve n¹, communicates with a
supply pipe B, which enters the tank or chamber C and leads the liquid and gas
thereto. With the pipe B, is connected a gas supply pipe 12, which conveys gas
From any suitable reservoir or other holder to said pipe B, so that it will pass with
the liquid from the cylinder i, through the pipe B into the tank or chamber..

page_text: The valve chamber m, (see Figures 1 and 3), is in communication with the
pipe d', and thence with the tank or chamber C, preferably near its lower portion.
The exhaust passage from the cylinder h, which passage is controlled by said
valve m', is in communication with a draw off pipe d, having any
suitable valve to control or cut off the fluid that may pass through said pipe.
The operation of the apparatus so far as has been described is as follows:
Assuming that the tank or chamber C is more or less filled with the aerated
beverage which is to be drawn off, such beverage being under pressure will flow
by the pipe d, to the valve chamber m, into the cylinder h, at one side of the
piston filling such cylinder and in condition to be drawn off whenever the valve
in the draw off pipe d, is opened. Whenever the valve in the draw off pipe is
opened the liquid on one side of the piston h¹, is allowed to pass out through said
pipe under the pressure in the tank, thereby permitting the pressure of the liquid
on the other side of the piston to move said piston so that it may at the same time
aid in forcing the liquid on the other side of the piston out through said draw off
pipe. As the piston moves in the cylinder, one of its collars strikes the rocking
lever and shifts the valves m, n, so that the other side of the piston h', is open
through the exhaust passage to the draw off pipe d", to repeat the operation just
described whenever the valve in the said pipe is again opened. While this is
taking place, water in the cylinder i, on one side of the piston ¹, is in communi-
As soon as
cation, through the exhaust passage of that cylinder, to the pipe B.
the pistons move this water will be forced into said pipe B, and the water entering
by the pipe A, will pass by its own pressure to the other side of the piston, ready
to be likewise forced into said pipe B, after the valves have been shifted as before
explained, upon the return motion of the pistons. These operations will bo
repeated each time the liquid is drawn off from the pipe d¹¹.
P,
The pipe B extends into the tank or chamber C, and forms the uppermost bear-
ing for a vertical stem X. Immediately adjacent to said stem the pipe is pro-
vided with orifices opening downwardly into the chamber C for the passage of the
liquid and gas into said chamber.
This vertical stem X, supports a number of flanged shaped discs or shallow
vessels arranged in pyramidal form, the smaller one of the vessels located near
the top of the stem, and the largermost one near the bottom. These vessels are so
arranged that the uppermost one is immediately below the discharge orifices from
the pipe B, so that the liquid and gas in passing into the chamber will immediately
pass or fall or impinge against said vessel and collect therein to the height of the
flange or edge of said vessel, and overflowing therefrom will pass into the next
lower vessel, and so on until the intermixed gas and liquid is collected in the
bottom of the chamber C, from whence it may be withdrawn as before indicated.
The several vessels are so arranged and located a distance apart that the gas
accumulating in the chamber under more or less pressure will be in constant
contact with the surface of the shallow-portions of the liquid which is contained in
each of the several vessels. As the liquid discharged into the chamber C falls
or overflows from one vessel into another through an atmosphere of gas, and while
falling, being thereby subjected to more or less agitation, it necessarily results
that by the time the liquid leaves the last or lowermost vessel it will have become
thoroughly impregnated with the gas, that is not only being fed into the chamber,
but by that contained in the chamber. The liquid therefore at the time it collects
at the bottom of the chamber having passed from its discharge orifice in a dis-
seminated or spray-like stream and collected in the several vessels in shallow
layers will have absorbed the maximum of gas which it is capable of doing, and
thus the collected liquid will have become thoroughly saturated with the gas, 50
that a beverage is formed ready for use in its most perfect" state.
From the foregoing it will be understood that the improved apparatus provides
cútomatic means controlled by the draw off of the required amount of beverage
to re-supply the tank or chamber with a like quantity of beverage so that there is
à constant quantity of beverage always contained by the tank or chamber.
