the~ water level through the medium of the con
trol valve 3 and the supply pipe 4 and this coun
ter pressure gas is maintained at a pressure of
approximately thirty pounds. Due to the open
20 ing of the counter pressure valve“, gas is ad
mitted to the bottle until the bottle is practically
?lled. By this time, the top of the supporting
tube 21 will engage the stem 24 of the water
supply valve, thereby opening the water supply
valve and permitting the water from the tank I
to ?ow through this valve and through the water
tube into the bottle, the valve l2 of the tube hav
ing at the same time been opened by suitable
mechanism not shown. Due to the fact that the
30 gas pressure in the bottle is equal to the gas pres
sure above the water in the tank I, the water vwill
?ow into the bottle under its own head only and
thereby ?ow comparatively slowly without caus
ing material agitation. At the same time that
35 the water is ?owing into the bottle through the
water tube, the gas is ?owing out of the bottle
through the counter pressure tube and back into
the top of the tank. The water continues to ?ow
into the bottle until it has covered the openings
40 l9 at which time it will be caused to stop simply
because the top of the bottle is sealed by the seal
ing ring 35 and passage of gas from the bottle is
stopped by the closing of the opening l9. There
fore, with no chance of escape for the gas above
45 the water in the bottle, the water cannot continue
to ?ow into the bottle. As soon, under normal
operation, as the bottle becomes ?lled, it com
mences its downward stroke, ?rst permitting the
water valve iii to close, and then the gas valve 20.

In the commercial machines, as heretofore con
foam, causing the bottle to boil over.
In either event, the accumulation of water in
the counter pressure tube has heretofore been
an objection and as a result, the machines have
not operated one hundred percent efficiently.
To overcome this objection and to prevent the
back?ow of liquid into the counter pressure tube, 20
when ‘the machine is stopped for any reason, I
provide the means disclosed more particularly in
Figs. 1 and 3 of the accompanying drawings. To
this end, each of the counter pressure gas tubes
9 in the tank, is connected to a gas manifold 31 25
by means of a suitable pipe 38. This gas mani
fold 31 may take the form of a circular pipe
mounted in the top of the tank and the connec
tions 38v may take the form of suitable ?exible
copper tubes extending from the top of each of 30
the gas tubes 9 to the manifold 31. At one point,
the manifold 31 is connected with a valve com
municating with the top of the tank, above the
water level, and to this end, I provide a valve
comprising a body portion 39 provided with a 35
head 40. The head 40 receives the two free ends
of the manifold 31 and is secured to the body 39
by suitable bolts 4|. This body is provided with
a valve port 42 on its underside which port is
normally closed by means of a valve 43.
40
For the purpose of controlling the valve 43, I
provide a diaphragm structure comprising a
housing 44 provided with a stem 45 extending
through a boss 46 in the top of the tank and
secured in position by means of a suitable nut
41. This housing, 44 is provided on its bottom
face with an annular shoulder 48 against which
is clamped a diaphragm 49 by means of a ring 59
extending from the valve housing 39. The dia
phragm 49 is clamped between a pair of dia 50
structed, and embodying the above construction,
phragm plates 5| and 52, the plate 52 having
if, for any reason, the machine should be stopped
during its operation, with the water valve and
the gas valve both open, there will be a tendency
56 for the weight of the water in the tank to force
the water from the bottle up through the counter
a stem 53 formed thereon extending through the
pressure tube and the various passages connect
ing it with the gas tube. If the period of stop
page is long enough, this water will ?ow upwardly
00 and into the gas tube until it reaches the level
of the water in the ?ller tank. Under these cir
cumstances, when the machine is again started up
and a fresh bottle engages the filler valve with
its counter pressure passageway ?lled with water,
65 the counter pressure in the bottle cannot estab-'
lish itself to its fullest extent before the water
valve I6 is opened, and as a result, the full coun
ter pressure is not established in the bottle, thus
permitting the, water to ?ow violently into the
70 bottle, therebytending to close the ball valve 36
and thus stop any further ?ow of water into the
bottle. As a result, the bottle will not be properly
?lled with water. This failure on the part of the
counter pressure to establish itself in the bottle
is due, of course, to the fact that before the gas
diaphragm through the plate 5|. and receiving
a clamping screw or nut 54.
For biasing the
diaphragm 49 in its downward position, I inter
pose between the top of the diaphragm and a.
shoulder formed in the stem 45 a coiled spring
55. The plate 52 is formed on the upper side
of a yoke 56 which surrounds the casing 39 and
on its underside is adapted to receive the valve 60
43. To this end, the yoke is provided with a
hollow plug 51 threaded into the yoke and receiv
ing a cushioning spring 58. The valve 51 is pro
vided with a stem 59 which extends through
the spring 58 and through the bottom of the
plug to receive a holding pin 60. It is thus seen
that the valve 51 is thus cushionedly supported
in the yoke and will have a certain amount of
movement relatively to the yoke.
The chamber above the diaphragm 49 and in 70
the housing 44 is adapted to be placed in com
munication with the source of supply vof CO2.
It is to be borne in mind that the control valve
3 has a swiveled connection with the' tank I
due to the fact that the control valve proper
3
9,118,480
remains stationary while the tank and its associ
ating ?lling valves rotate. To this end the con
-trol valve 3 is provided with a nipple 6| ‘pro
vided with a supply tube 6|’ entering the top of
the tank I through a' suitable swiveled joint
62. An' additional swiveled ring 63 surrounds
the nipple 6| and this ring is connected by a.
pipe or conduit 64 with the stem 45 of the,
diaphragm housing.
10
-
This swiveled ring provides a connection be
tween the chamber in the housing of the dia
phragm and the source of gas supply delivered
through the control valve 3. To this end, the
ring 63 surrounds the stem 60 of the valve 3,
being rotatable relative thereto, and is provided
iectively seals the upper end of the counter pres
sure supply tubes 9 and it is obvious that-with
one end of the counter pressure tube l9‘ closed
or sealed, it would be impossible for liquid to
?ow up into the tube so that as long as the ma
chine remains stopped, the how of liquid into
the counter pressure tube will be e?ectively pre
vented and as soon as the machine is again
started up, it will start to operate in the normal
manner and without having to eject ?uid which
:may have passed into the counter pressure tube.
I claim as my invention:
1. In a bottle ?lling machine, having a con
trol member for starting and stopping the same,
the combination with a filling valve including a 15
counter pressure tube, of means for sealing the
with an annular recess 65. The top of this recess . inlet to said tube, and‘ means controlling the
is closed by a plug screw 66. Within the recess operation of said sealing means operated by said
or groove thus formed, I arrange a ring 61 hav
control member when the same is moved to stop
ing an annular lip- 66 hearing on the top of a the machine in any ?lling position with the ?li 20
separate ring 69 thus forming an annular groove ing valve in discharge condition to thereby pre
‘I0 communicating with a port 'II in the nipple
back ?ow of liquid into said tube.
6| and having an opening connecting with a port vent
2. In a bottle ?lling machine, having a control~
‘I! in the ring which port in turn communicates
. with the conduit 64. Suitable packing material
25 is arranged within. the recess in the ring to pre
vent the escape of ‘gas and the rings 68 and 69
are so clamped in position by the plug 66 that
they form a unit with the swiveled ring 63 and
rotate therewith. . The port 1| communicates
30 through a port 12' in the nipple 6| with'a con
duit ‘I3 extending to a valve 14 preferably mount
ed on the table 6 and controlled through a suit
able handle 15 connected by a link 16 with
the clutch lever 11. By the movement of the
: clutch lever, the opposite side of the valve 14 is
connected by a conduit 18 with the nipple 6|
so that in addition to supplying gas to the top
of the tank I a by-pass is provided through the
pipe ‘I6. The valve 14 comprises an ordinary
three-way plug valve as shown in Fig. 4.
In normal operation, the valve 14 is in the
position illustrated in Fig. 4, thereby establishing
communication between the pipe 18 and the
pipe 13. Therefore, under these circumstances,
pressure from the control valve 3 will pass
through the pipe 18 through the valve 14, through
the pipe 13, by the way of the conduit 1| and
through pipe 64 to the chamber in the housing
44 above the diaphragm 49., Due to the _fact
that this pressure is equal to the pressure in the
top of the tank |' and, therefore, the pressure
exerted against the underside of the diaphragm,
the gas pressure on either side of the diaphragm
is balanced and the spring 55 can and does exert
su?icfent bias to maintain the valve 51 open so
that the counter pressure tubes 9 are placed in
communication with the top of the tank I to
receive counter pressure gas in the normal man
ner and to permit the operation of the ?ller
valve, as heretofore described. If, however, the
60 machine is stopped by the throwing of the lever
TI to disconnect the clutch, the valve 14 is moved
to a position to close communication between
the pipes 13 and ‘I6 and open communication
, between the pipe 13 and the atmosphere through
the port 80, in the valve, and the port 8|, in
the valve casing. This places the chamber above
the diaphragm in communication with the at
mosphere through the conduit 64, the port ‘II
75
and conduit 13; There being no pressure of gas
on the upper side or the diaphragm and the
diaphragm being exposed to the gas pressure in
the tank I, the diaphragm will be ‘moved up
wardly under the in?uence of this pressure mov
ing the valve 43 to closed position. This et
