when rotative movement is imparted to the
shaft 89, the agitator paddle 18‘ is rotated, and
the curved vanes ‘I2 agitate the water and car
bonic gas in the carbonator tank 29, causing the
carbonic gas to permeate the water, producing a
65 carbonated water suitable for mixture with ?av—
orlng syrups or for use unadulterated.
Water traversing the water conduit means
herein described is co'oled to a low tem
, perature before entering the carbonator tank
70 29 and prior to coming into contact with the
- carbonic gas.
I find that with my method of
preparing carbonated water by cooling the water
prior to mixing with the carbonic gas and then
agitating the water and gas in a cold state, that
75 a larger amount of gas can be absorbed by the

water from flowing to the carbonator tank 28. ,
A motor 98 is mounted on a platform 81 and
the shaft 88 of the motor 98 is connected to the
end of the shaft 11. When the motor 88 is op
erating, it imparts rotative movement to the 60
shaft 11 which in turn actuates the agitator pad
dle ‘I8 and the valve stem 48, as hereinbefore
described.

An electrical circuit I88, not completely shown,
includes a mercury switch IN, or other suitable
switch means‘, enclosed in a sealed compartment
I82 ?xed to the end wall 28 of the carbonator
tank 28. The switch IN is provided with a lever
arm I88 pivotally mounted, at about its mldsec
tion, on the end wall 28, and the ‘lever arm I88 70
has at one end ?ngers I84, securing a sealed
glass' tube I85 carrying at one end electrodes I88.
In the tube I85 is a quantity of mercury which
makes or breaks the circuit through the elec
trodes I88, depending upon the inclination of the 75
3
. 2,077,850
tube I05 and the resultant location of the mere
cury, either in or out of contact with the elec
trodes I06. The opposite end of the lever arm
I03 is provided with an elongated slot I01 in
'5 which is inserted one end I08 of a ?oat rod I09
pivotally secured, as at IIO. This arm extends
through a slot I I I in the wall 28 of the carbonator
tank 29 and carries at its other end a ?oat II2
adapted to be moved in a vertical arcuate line by
10 the carbonated water in the carbonator tank 29.
The cover 39 of the carbonator tank, 29 has an
upwardly bulged portion I I3 to accommodate the
?oat H2. The bulged portion H3 is provided
with an inwardly threaded boss I I4 for the re—
15 ception of a safety valve I I5. This valve includes
a valve casing II6, a valve .seat In, a valve H8,
outlets H9, and an adjustable pressure spring
I42 is manipulated, a disk I45 threaded to one end
of a valve rod I46 slidably mounted in the aper
tures I31 and I3I.
r
The opposite end of the valve rod I46 is slid
ably mounted in a partition wall I41 disposed
short of the end I48 of the tubular member I2I.
The valve rod I46 extends into the carbonator
tank 29 and is adapted to engage a valve 30I pro
vided with a valve disk I49 mounted on a plung
er 300 having a stud I50 slidable within a recess
I5I of a valve cap I52 threaded to the extreme
end I48 of the tubular member I2I. The valve
30I is yieldably mounted by means of a spring
I53 interposed between the valve cap I52 and the
plunger 300. The valve cap I52 is provided with‘
annularly arranged ports I54, and the partition
wall i4’! is provided with ports I55 to establish
I20, permitting the valve II8 to be unseated at
communication between the interior of the car
a predetermined gas pressure within the car
bonator tank 29 and the interior I56 of the tubu
lar member I28. The flow of carbonated water
from the carbonator tank 29 is controlled by the
20 bonator tank 29.
_
The level of the water in the carbonator tank
29 controls the movement of the ?oat I I2. When
the carbonated water supply is depleted to a pre
determined level, the ?oat rod I09 automatically
25 actuates the switch lever arm I03 which is moved
upwardly, as shown in broken lines in Figure 8,
and the mercury tube I05 is inclined to contact
, position with the electrodes I06 to close the cir
cuit, causing the motor 96 to‘operate and rotate

wardly moves the valve rod “6 inwardly to open
the ports 654 and permit the flow of carbonated
water through the ports I55 and I30’ and thence
from the discharge nozzle I33.
The tubular member i2! has a ?at surface, as
at 860, to support a cylinder “ii, of predeter
mined capacity, having a tapered port l62, adapt

lugs I39. The pin I38 is rigidly affixed, by means
of a screw I40, to the‘ bifurcated arms I4I of a
faucet handle I42, and secured to the pin l38,
within the chamber I34, by a screw I43, is a cam
75 I44, adapted to engage, when the faucethandle
ably held in position by a spring i9I removably
secured by a spider‘ member I92 af?xed at the
inner end of the bore I91. The outer end of the 70
bore- i8‘! is outwardly and upwardly tapered to
frictionally accommodate a correspondingly ta
pered ?exible member l93 secured to a nipple 594
abutting against the bottom-of a syrup container
I95 and secured thereto by "acollar I96. The 75
4
8,077,850
syrup container I95 is supported in the bore I01,
and is easily removed from the cabinet I 2 by lift
ing it upwardly from the bore I81. Additional
syrup may be added to the container I95 by re
5 moving a detachable plug I91.
In operation, assuming that the apparatus is
in the position as shown in Figure 9, and the
cylinder I5I has not been supplied with ?avoring
syrup from the syrup container I 95, the faucet
l0 handle I42 is rotated forwardly, which movement
unseats the valve I90 and causes the elements
associated therewith to assume the position as
shown in Figure 10, creating a partial vacuum
in the cylinder IGI, causing syrup to flow from
200, terminating in a pipe 205 having one end
threaded to the end of the faucet 204 and the
other end terminating within the carbonator
tank 29 in direct communication with the car
bonated water therein. The inner end of the
faucet 204 is secured to the inner [surface of the
front wall of the ice-box 2I by a gasket and nut
arrangement as indicated at 2I0. The inner
end of the pipe 208 is secured to the carbonator
tank 29 by a gasket and nut arrangement as 10
shown at 2i I.
'
When the faucet handle 205 is moved for
wardly, the carbonated water is dispensed with
considerable force through the reduced outlet
205, the force of the ejection being su?icient to
