Definitions

  • This invention relates to a connecting head for use with casks, siphons and the like receptacles of the type adapted to contain liquid under pressure, and more particularly to a connecting head for use with metal casks as used in the brewing industry for containing stout or beer under the gaseous pressure of a carbonating gas.
  • the carbonating gas may conveniently be contained in a separate chamber fitted within the cask, the pressure of the carbonating gas being higher than the gaseous pressure to be applied to the liquid in the cask, communication between the gas chamber and the liquid in the cask being effected through a pressure reducing valve also located within the cask, the arrangement being such that as liquid is drawn oil from the cask, the reduction of gaseous pressure in the cask resulting therefrom is augmented automatically by admission of additional gas from the gas chamber through the reducing valve into thet-op of the cask.
  • Constant gaseous pressure is thereby maintained on the liquid within the cask, and this pressure serves to discharge the liquid, as and when required, through a siphon tube extending from near the bottom of the cask to a valve cont-rolled outlet located in the top of the cask,
  • Such known casks are usually provided with three valve controlled openings in the top thereof for effecting communication with the gas chamber, with the siphon delivery tube and with the top portion of the cask above the liquid therein.
  • the valves controlling the openings are conveniently of the spring loaded poppet type which are maintained in their closed position under spring pressure assisted by the gaseous pressure in the cask and are opened by the application thereto of downward axial pressure for charging or emptying the gas chamber or the liquid containing portion of the cask.
  • connector head for use with such casks, the connector head being adapted for detachable mounting in seal-proof manner upon the top of the cask and incorporating manually operated means for opening the liquid discharge valve on the cask head and/or the gas inlet valve and at the same time effecting communication between these valves and passageways in the connector head, whereby the liquid contents of the cask may be discharged as and when required, or the connector head may be used for filling or racking of the cask with beer or sterilising the cask with steam or gas prior to refilling.
  • the connecting head is adapted to open all the three valve controlled openings in the cask and to simultaneously establish communication directly with the siphon tube delivery from the cask for discharging the contents through a passageway provided therefor in the connecting head, as well as effecting communication between the separate gas chamber and the top portion of the cask above the liquid therein through a reducing valve incorporated in the connecting head,
  • the present invention comprises a connecting head for detachable mounting upon the top of casks, siphons and the like receptacles of the type stated in which the receptacle has three valve controlled openings in the top thereof communicatin respectively with the top of a liquid contained in the receptacle, with a siphon delivery discharge for the liquid, and with a separate chamber within the receptacle containing a gas under pressure.
  • the connecting head comprises a valve actuator element adapted for vertical axial downward movement within a casing against the action of spring means tending to return the actuator element to its uppermost position, two throughway passages formed in the actuator element terminating at their lowermost ends in nozzles which, on downward movement of the actuator element, communicate with and open the valve controlled openings in the top of the receptacle communicating with the top of the liquid and with the sip-hon delivery discharge therefor, a pressure reducing valve carried on the exterior of the actuator element to partake in the movement thereof and fitted with a nozzle at its inlet and adapted to communicate with and open the valve controlled openings in the top of the receptacle communicating with the gas pressure chamber, manual actuating means mounted on the casing for effecting downward axial movement of the actuator element against its return action and for maintaining the actuator element in this position, the outlet from the pressure reducing valve being connected to the uppermost end of the actuator element passageway which communicates with the top of the liquid in the receptacle, and the top of the other passageway
  • the connecting head according to the invention obviates the necessity for providing a reducing valve connection within the cask between the gas pressure chamber and the top of the liquid containing portion of the cask.
  • the gas pressure chamber and the liquid con-t aining portion of the cask remain unconnected and sealed off from each other during transport and storage of the casks and no leakage therebetween can occur.
  • the necessary intercommunic-ation between the gas chamber and the liquid containing portion of the cask, and the dispensing of the liquid contents can only be eifected when the connecting head is fitted to the cask and actuated to open the valves on the cask.
  • each public house, lounge or similar establishment to which filled casks are sup plied will be furnished with a connecting head for detachable mounting on each cask as the cask is required for use, the discharging passageway on the connecting head being connected by flexible hose to a bar counter tap for dispensing as and when required at the bar counter.
  • the one connecting head serves for dispensing from a large number of casks separately, the connecting head being adapted for easy mounting to and detachment from each cask.
  • FIG. 1 is a perspective view of the connecting head.
  • FIG. 2 is a vertical sectional view of the connecting head.
  • FIG. 3 is a cross-sectional view of the line HIHI of FIG. 2.
