  • the upper surface 66 of adapter member 48 is provided with a counterbore 216 while the center portion of web ⁇ 68fis provided with an annular groove 218.
  • a screen element 220 is retained in the counterbore-216 and groove 218 and provides a means for automatically stopping the flow of liquid to the container when ⁇ the pressure of the gas in ⁇ the head space of the container is balanced with the pressure of liquid above the screen. The natural surface tension of the liquid with the screen will prevent further liquid from flowing into the container.
  • the lower portion 80 of gas tube 22 is provided with an aperture 222 abowe its outlet 224.
  • a modiiied means for automatically stopping the flow of liquid into the container after the liquid in the container has risen above the port 222 in gas tube 22 is disclosed in Figures 25 and 26.
  • liquid valve 18 is provided with an annular ange 226 on its outer sleeve 104.
  • An annular space 225 between the annular flange 226 'and the wall of the aperture 34 in the bottom wall 32 of tank 14 defines a restricted passage for the flow of liquid through valve 18 when the valve is open-
  • This restricted passage has a width in the order of .040 of an inch and this is determined by the viscosity and surface tension of the liquid being handled, for example, a carbonated mixture of one part of 30 Baume syrup andve parts water.
  • the spacing between the flange and the wall of the aperture may be ⁇ increased and, conversely, if the liquid has a less viscosity and surface tension, the spacing may be decreased.
  • the modified form of invention disclosed in Figures 25 and 26 is preferably used when filling with a carbonated liquid containing a mixture of pulp or the like which would ordinarily clog the screen of the form of the invention shown in Figure 22.
  • a screen with some pulp or carbonated liquid mixtures.
  • the .liquid flow is ⁇ stopped right at the point where the liquid valve A is opened and closed.
  • the advantage of stopping the flow at the point where the liquid valve is opened or closed is that no liquid remains in the liquid passage below the liquid valve and no gas remains ⁇ in the passage above the liquid valve when ⁇ the liquid valve is positively closed by cam 44. ⁇ This results in more even iilling of subsequent containers -and a material reduction 4in foaming.
  • ⁇ filling heads of the present invention would be provided in association ⁇ with the annular filling reservoir 14, and reservoir 14 would be lsupplied with carbonated liquid and asuperposed body of gas by any system usual to rotary counterpressure fillingv machines. Suitable means would be ⁇ provided to maintain a substantially constant level of' the liquid in the reservoir while the machine is in operation.
  • Empty containers C ⁇ are successively transferred to container supporting ⁇ platforms 10 as the container supporting platforms pass an inlet station on the work table of a filling machine.
  • the containers are raised into sealing engagement with the sealing rings 54 and as the filling machine rotates, the container is then subjected to the various stages of the filling cycle which are described under separate headings below.
  • CLOSED STAGE Figures 2, 3, 4 and lil illustrate the position the iilling head valves will occupy during ⁇ the closed stage.
  • the iilling head ordinarily lwill be in this condition after a container had been moved downwardly from the filling head and when an unfilled container is received by the lling head.
  • valve trip arm 46 is in position A disclosed at the righthand sideof the schematic view of Figure 11.
  • cam follower l186 is bearing against a high point 300 on the cam surface 154 and, thus, valve stem 108 is at its lowerrnost vertin can position causing liquid valve 16 to seal tightly against valve seat 67.
  • lGas valve 18 is also closed, it being held in closed position against the spring tension of spring- 210 by a high point 302 on cam surface 152.
  • the high point 302 of cam surface 152 is holding gas valve 18 downwardly in its lowermos't position so that the ⁇ gasket 172 carried by the gas valve is pressed into sealing engagement with the upper end of gas tube ⁇ 22.
  • container C While the filling head is in the closed stage, container C is elevated vertically into engagement with the gasket 54 of nozzle structure 20 and the container is then in sealing relationship with the filling head and is ready for lthe filling operation.
  • Trip 304 rotates the trip lever 46 ⁇ to the position disclosed in Figures 5, 6, 7 and position B of schematic view ⁇ Figure l1.
  • gas valve 18 is open a maximum amount so as to permit gas rom the upper portion of reservoir 14 to flow quickly through the passages 182, and 178 downwardly through gas tube 22 into the container as indicated by the arrows in positi'onB of Figure ll. p
  • cam surface 154 which ⁇ normally engages cam follower 186 to close liquid valve 16, falls away from carnfollower 186.
  • a ⁇ low point or dwell 308 will beabove cam follower ⁇ 186 ⁇ to thereby permit cam follower 186 to be spring urged upwardly into engagement therewith when the pressure of gas flowing into the container builds up to lan amount which substantially balances with the .pressure of the ⁇ liquid acting on the ⁇ surface 208 ⁇ of liquid valve 16.
  • cam 44 When in position C, which is the filling and venting stage position, cam 44 will have rotated approximately 110 and cam surface 152 will have a dwell or low point 316 which partially closes gas valve 18 as On the other hand, cam surface 154 will have a dwell or low point 318 which is even lower than the dwell or low point 308 and, thus,
  • valve actuating stern 108 will be moved upwardly further ⁇ to open liquid Valve 16 to its maximum position.
  • liquid flows downwardly through liquid passage 26 as indicated by the arrows ( Figure 1l) and is deflected outwardly against the walls of container C by a deflector 320 carried on the central gas tube 22.
  • Counterpressure gas in container C flows in the direction of the arrows ( Figure 11) through gas tube 22 back into the reservoir above the level of liquid therein.
  • the liquid flowing into container C is automatically stopped when the level of liquid in the container reaches a predetermined height even though the valves of the lling head may be open as shown in Figures 8, 9, and 1l. Liq-e uid liowing into the container eventually covers the port 222 in gas flow tube 22 and when this condition occurs,
  • a modied means of stopping the ilow of liquid into the container does not include the screen 220 but relies on a restriction 225 in the liquid passage 26.
  • the restricted passage 225 is defined by the liange 226 on the periphery of liquid valve 16 and the wall of the aperture 34. The distance between the wall and the liquid valve is controlled so that when the pressure builds up in the head space of the container, the surface tension of the liquid is sufficient to prevent further liquid from flowing into the container.
  • a xed trip (not shown) engages the valve plunger 94 of snift valve 24 and opens the head space of the container to atmosphere to thereby relieve excess pressure in the head space of the container.
  • the trip 94 is only momentarily held -open as this is sufiicient time to relieve the excess pressure in the head space of the container.
