Improvements in Aerating or Carbonating Apparatus.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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: --
The invention relates particularly to apparatus for carbonating water such as
is used in bottling establishments and in establishments for the retailing of soda
water, such as drug stores and the like. The object of the invention is to provide
a simple, economical and efficient apparatus for automatically carbonating a
supply of water as it enters a receiver, and stopping and starting such supply
whenever the carbonated water is furnished or withdrawn from the receiver;
and the invention consists in the features, combinations and details of construc-
tion hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a side elevation of a carbonating
apparatus constructed in accordance with the improvement; Fig. 2 a plan view
of the same looking at it from the top; Fig. 3 an enlarged detail view of the
electric switch and attached mechanisms: Fig. 4 an enlarged sectional detail of
the T-shaped plug and pipes at the head of the receiver taken on the line 6 of
Fig. 2; Fig. 5 a sectional detail of the same mechanism taken on the line 5 of
Fig. 2 and Fig. 6 a cross sectional view taken on the line 6 of Fig. 4.
In the art to which this invention relates it is well known that it is highly
desirable to have a carbonating apparatus so constructed and arranged that the
water as it enters the same may be saturated with carbonic acid gas and when
the receiver is filled that such saturation and supply of water will be stopped until
a sufficient quantity has been withdrawn to make it necessary to again furnish
a supply of water and saturate the same with carbonic acid gas during its
entrance into the receiver. The invention therefore is intended primarily to
provide a simple, economical and efficient apparatus of this style, all of which
will more fully hereinafter appear.
In constructing the apparatus a platform A of any desired size, shape and
strength is provided upon which the receiver B is mounted at or near one end,
and a pump C at or near the opposite end adapted to be operated by means of an
electric motor D which for convenience may be mounted at or near the same or
adjacent to the same. This platform is of that class of platforms which may be
described and is considered as a tilting platform and which has its tilting

page_text: journals a resting in suitable bearings on the standards E so that the platform
with its apparatus may be tilted or rocked first to one side and then to the other.
To furnish a supply of carbonic acid gas to the receiver so that it may saturate
the incoming supply of spraying water a gas supply pipe I is provided and con-
nected to the plug by means of a union or otherwise so that the supply of gas
enters and passes down and through the opening i in the plug. This gas supply
pipe, it will be understood, is connected with a tank containing a supply of
carbonic acid gas under pressure and which has the usual equalizing valves and
other mechanism-unnecessary to illustrate and describe herein for the reason
that they are well known to those skilled in this art.
To furnish a supply of water to the receiver a water pump C is provided which
has a crank shaft e provided with a crank plate c¹ operating a plunger C¹ by
means of a connecting rod c². A supply pipe G leading from any suitable source
of water supply communicates with a valve chamber of the pump, and a discharge
pipe G is connected with the inside portion of the valve chamber and with an
opening in the plug H through which the water is fed into the reservoir and
atomized by means of the two small pipes h¹ at the lower portion of the opening.
It will therefore be seen from this construction and arrangement that when the
pump is working the supply of water is fed to the receiver and when such pump
is stopped no water is fed to the receiver.
To actuate the water pump at the proper times an electric motor D is provided
and connected with a source of electric energy by means of the wires and d
which in turn are connected to binding posts on the switch K. The continua-
tion of the wires and lead through the switch K to the proper source of
electric energy. When the electric motor is supplied with its proper amount of
current it rotates so that its armature shaft d rotates and by means of the pin-
ion operates the train of compound gears and d to operate the driven gear de
on the crank shaft of the motor.
When the receiver is full of carbonated waters that end of the platform is tilted
so as to be close to the ground or floor and as a consequence the operating rod L
releases the switch lever k from engagement with the binding posts and interrupts
the current so that the electric motor is stopped. As the carbonated waters are
drawn off from the receiver through the exit pipe M the receiver is gradually
emptied and when its weight with the amount of material therein is less than the
combined weight of the motor and pump they will overbalance the same and
cause the platform to tilt to the other side. At the same time, the operating rod
is turned downwardly by the platform and operates a switch lever so as to close
the same, furnish a supply of current to the motor and rotate it to operate the
pump and furnish a supply of water to the receiver.
The exit pipe M is connected with the plug and in line with the discharge
opening m in such plug which has its pipe running down to or close to the bottom
of the receiver so that nothing but the charged waters can be drawn off until the
receiver is emptied. This plug is also provided with a vent opening N and screw-
plug for the purpose of withdrawing either the supply of carbonic acid gas or
to permit air, as the water is being fed in initially, to be forced out therethrough.
The controlling rod as will be seen in Fig. 3, is provided with two cushion
springs and which act to cushion the force transmitted by the movements of
the tilting platform to the switch lever so that it can be operated without a
shock. The collar 12 adjustably secured to the upper rod so as to get the
desired tension and operate the switch faster or slower and at such time or times
as may seem desirable or necessary.
While the invention has been described with more or less minuteness as regards
details of construction and arrangement and as being embodied in certain precise
mechanisms, it will be understood that it is not intended to be limited thereto
.unduly any more than is pointed out in the claims; on the contrary, it contem-
plates all proper changes in form, construction and arrangement, the omission of

page_text: immaterial elements and the substitution of equivalents as circumstances may
suggest or necessity render expedient.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is:-
1. In an apparatus of the class described, the combination of a rocking or
tilting platform, a mixing vessel or receiver on one end of the platform, a pump
on the other end of the platform for supplying water to the mixing vessel, an
electric motor connected with a source of electric energy, and means for cutting
off the supply of electric energy to the motor and during the movements of the
rocking platform, substantially as described.
2. In an apparatus of the class described, the combination of a rocking or
tilting platform, a receiving or mixing vessel on one end of the platform, a water
pump on the other end of the platform for supplying water to the mixing vessel,

form, an electric switch for cutting off or furnishing a supply of current to the
electric motor and means for opening and closing the switch by and during the
movements of the rocking platform, substantially as described.
3. In an apparatus of the class described, the combination of a rocking plat-
form, a receiving or mixing vessel at one end of the platform, a water pump on
