(Cl. 226-115) / My invention relates to improvements in bottle ‘ although the control valve 3 is adapted to remain ?lling machines and particularly to that type of . stationaryjdue to its connection with the CO: bottle ?lling machine commercially known as the supply pipe 4. However,'a swiveled joint or con counter pressure machine wherein the bottle is nection extends between the valve 3 and the top 5 adapted to be ?lled with a carbonated liquid, the of the tank, permitting relative rotation. Each the ?ller valves 2 is connected with the water bottle being initially supplied with a charge of of supply through a conduit ‘I and'with a gas sup CO: at a pressure equal to the CO3 pressure in the liquid tank above the liquid so that there is ply through a conduit 8 which communicates va balance of pressure established in the tank and‘ ‘with a gas tube 9 in the tank, opening above the 10 water level in the tank.v In order to understand in the bottle whereby when the liquid is admit ted, it ?ows merely under the head established the operation of the ?ller valves, reference may in the tank. In certain types of machines of this character, if, for any reason, the machine is stopped dur H in ing the course of itsoperation, the valve con trolling the counter pressure tube under certain circumstances, will remain open so that there will be a tendency for the liquid from the tank to ?ow into the bottle andthence over?ow through and 20 into the counter pressure tube, resulting, when the machine is again started, in either the next succeeding'bottle becoming only partially ?lled with the liquid or in foaming or other objection I be made to the sectional view of the ?ller valve shown in Fig. 2. As shown in this structure, the valve body in has extending downwardly there from a water tube‘ H closed at‘ its lower end‘ through the medium of a valve i2 operated by a rod i3 extending upwardly through the tube I I to an“ operating stem I4. This'tube II communi cates through the port i5 with a water control ‘valve It in turn controlling the passage of water from the chamber l‘l connected with the water ‘ tank through. the water connection 'I.

The valves 16 and ' Fig. 3 is a sectional view of a filler tank show 20 are respectively .provided with stems 24 and ' ing the over?ow prevention means; and 25, the stem 24, as illustrated, being shorter than Fig. 4 is a-detailed section of the over?ow pre the stem. 25 for purpose more fully hereinafter vention‘ means controlling valve. to appear. A bottle engaging hell? or throat 26 In the embodiment of the invention illus '- is mounted at the lower end of a slidable tubular I trated, the ?lling machine embodies a ?ller tank support 21, which support at its upper end, sur-' 40 40 I provided with the usual ?ller valves 2. ‘In prac -rounds a relatively stationary tube 28 extending tice,‘the machine is provided with a number of these valves from 18 to 24, depending upon the downwardly from the valve l0 and the support able features occurring. capacity of the machine. - This tank is connected 21 is held against extreme downward position by with the usual water supply and is likewise con an annular ?ange ,29 engaging beneath a collar 30 on the support 21. A coiled spring II biases‘ the throat 26 and its associated support in a ' nected with a C02 supply through the medium oi.’ the control valve 3 and a pipe 4. The bottles to be ?lled are received on vertically reciprocable ‘downward position, this spring being interposed rotating bottle supports 5, one for each valve, '_ between an annular ?ange32 on the tube 28 and which receives the bottles from a conveyor table a washer 33 stationarily mounted in the support 50 6. As the bottles are received on the supports 5, 21. In addition to the water tube and counter the. supports are raised, carrying with them the pressure tube heretofore described, there is pro bottles to be ?lled which, in turn, engage with the ,- vided an additional tube 34 which acts as a shift throat of the bottle valve, thereby controlling ‘er, tube and communicates, through a suitable the operation of the valve. The supports, the valve with the atmosphere. So far as the oper 65 55 tank and the bottle valve all rotate inunison 2 2,118,436 ation of the present invention is concerned, this snifter tube ‘need be further described. I In operation, when the bottle is raised on the bottle support 5, shown in Fig. 1, the neck of the bottle enters the throat 26 coming in contact can be admitted into the bottle, the water which has accumulated in the counter pressure tube, must be ?rst forced out. ~ If .the machine for any reason has not been stopped long enough to completely ?ll the coun with a sealing cushion 35. The continued up ward movement of the bottle raises the tubular ter pressure tube with water as heretofore de scribed, but only a small-amount of water is support 21 until the same comes in contact with _ forced up into the tube. when this small amount the stem 25 of the counter pressure valve. This of water is forced into the next succeeding bottle, 10 opens the counter pressure valve, admitting coun ter pressure, CO: from the top of the tank I it is forced in so violently that it forms a mist or fog in the bottle which settles on the top of through the counter pressure gas tube 9, the counter pressure valve 20, and through the coun ter pressure tube into the bottle. The supply the syrup and when the incoming carbonated water mixes with this mist, the material starts to 15 of gas or CO: is maintained in the tank above 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. 50 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.
