13 Claims.

My invention relates to a liquid dispensing device and more particularly to a liquid container and associated liquid control valve wherein means are provided to supply a gaseous medium under pressure to the container as desired.

The main object of my invention is to provide a container from which a beverage may be dispensed as used and having means associated with the dispensing valve for admitting to the container as desired a suflicient quantity of carbon dioxide gas to maintain a suitable pressure'within the container.

Another object is to provide in a dispensing container a means for supplying carbon dioxide gas thereto whereby to maintain the quality of the beverage and enhance its taste.

Another object is to provide in a dispensing container a means for charging the container either from a carbon dioxide capsule or by means of a solid portion of carbon dioxide.

Another object is to provide a metallic dispensing container that is adapted to be readily sterilized and refilled at the manufacturing plant, delivered to the consumer, stored by him in a household refrigerator, and charged by him as desired to ensure a proper dispensing pressure.

Another object is to provide in such containers a common means for controlling the delivery of beverage and the supply of gaseous medium to the container.

Although the pressure controlling and releasing faucet herein disclosed is particularly adapted for use in dispensing a draught beer, it is equally adapted to dispensing various kinds of carbonated waters. It is a matter of common knowledge that the trade has a pronounced preference for draught beer but, due to the elaborate and expensive type of equipment necessary to dispense such beer, present available apparatus 49 makes it almost prohibitive to dispense draught beer for domestic or club use. According to my invention, a dispensing container, preferably metallic and of relatively small content, is provided with a simple and inexpensive type of faucet that has formed integrally therewith a device for storing a suitable charge of carbon dioxide which may be admitted by increments as desired to the container.

A preferred form of the invention is disclosed in the specification which follows and the accompanying drawings, wherein Figure 1 is a view, partly in section of a metallic keg fitted With a dispensing device of the type described;

' Fig. 2 is a view, in side elevation, of the keg shown in Fig. 1;

Fig. 3 is an enlarged sectional view of the unitary dispensing and charging mechanism;

Fig. 4' is a view, partly in section, of the dispensing unit showing a charging capsule to be inserted; and

Fig. 5 shows a modified form of charge holder. As shown in Fig. 1, my improved dispensing device is shown preferably as applied to a container in the form of a metallic barrel or keg I which may be formed either from aluminum or stain-' less steel. This, container may be made rectangular, oval or round in cross-section according to the requirements of space or storage facilities. A plurality of leg portions 2 are provided to support the keg in a stable position. The container may be formed in sections as desired which are united by a' weld 3 and in a well known manner. A ring-like collar 4 is shown as welded in position concentric with an opening 5 provided in one end of the container. A threaded flange 6 is formed on the collar 4. My improved unitary faucet and charging device comprises two main sections. The gas storage section 1 has a fiangeii adapted to engage the collar 4 to posi tion this section within the container l and a threaded collar 9 engages the flanges 6 and 8 to retain the section 1 inoperative position. A gasket Ill may be employed to ensure against loss of container contents. A second or main capsule container H is connected to the section 1 by. means of a threaded joint l2. A capsule frame or holder I3 with a capsule in position is shown as inserted within the section II and is retained in position by a threaded coupling M. The end cap of this holder is fluted and serves as a grip to rotate the holder and pierce the capsule in a manner to be described.

A gas storage chamber I6 is formed in'the section I and the outer endof this chamber is closed by a threaded plug l1 and gasket [8. The plug l'l comprises a central auxiliary plug H) which is retained in position by rubber seat and ring ill. The plug I9 terminates in a piercing pin 22. A gas discharge bore 23 extends through the pin 22 and plug l9. Rotation imparted to the cap l5 will be efiective, when desired, to force the capsule 24 against the pin 22 in a manner to pierce the cap'suleand discharge its contents into the chamber IS. A check valve .25 serves to prevent return of gas through the bore 23. Any surplus or leakage of carbon dioxide in the chamber II is permitted to escape through aport 26 whereby no gas under pressure will remain in 7 this chamber. When the capsule holder 13 is unscrewed, the piercing pin 22 is fully withdrawn before the holder becomes free. 'Any gas liberated from the capsule at this. instant may escape through the port 26,. thereby providing a safety feature to prevent forcible ejection of this holder.

The gas is withdrawn from the chamber I6 7 through a lateral outlet 21 and its passage is con trolled by means of a valve 28 positioned in this outlet passage. The valve 28 is of a type in common use on tire tubes. The pin 29 of this valve is controlled by a plunger 30 which, in turn, is caused to reciprocate by means of a cam 3| formed on the tapered valve plug 32. The spring 33 in valve 28 serves to return the pin 29 and the plunger 30. The valve proper 28 is secured on the pin 29 and seats on asleeve 29'. Any carbon dioxide passed by valve 28 is conducted through a port 34 which has its outlet within the container I. A rubber band35 surrounding the section I is effective to close the port 34 and act as a check.

valve to prevent return of liquid or gas through this port. In the event that the valve 28.1eaks, the leakagegas may pass through a port 36 into the chamber II and out through port 26. When the plunger 36 is moved by the cam 3| to contact the valve pin 29, a rubber seat 3! on the inner .end of this plunger closes the port 36 and causes gas released by the valve 28 to pass through the outlet port 34 into the container I. 7

It will be noted that the chamber section II serves tosupport the faucet handle 38 and valve 32. The main body or casing 39 of the valve is formed integrally as a unit with the casing II and with the delivery spout 4|]. The handle 38 terminates in a yoke or fork 4|, the ends of which are secured rigidly by screws 42 to the valve 32. As shown in Fig. 4, a port 43 is formed in the valve and this port may be put in communication with the fluid delivery passage 44 when the hande 38 is moved in a forward direction. A

liquid pick-up conduit 45 is secured in one end of the passage 44 and is made of sufficient length to reach to the wall of the container I.

Fig. 4 shows the cap l5 and capsule holder I3 after the latter has been unscrewed and withdrawn from the, chamber II in order to refill this holder with another capsule 24.

Fig. 5 shows an alternative means for supplying a charge of carbon dioxide gas. A cup- I shaped carrier 46 is shown as internally threaded tamper with the handle 38 to deliver liquid prior to receive an axially adjustable threaded plug 41. The carrier 46 may be filled with a quantity of solid carbondioxide 48 as determined by the position of the plug 41. The carrier 46 terminates in a head portion 49 which may be formed as provided, respectively, in the cap |5, coupling collar 9, and the yoke 4! after which the seal'5l may be applied to this wire and, if desired, the insignia of the manufacturer may be inscribed thereon, which will ensure that no party will to breaking of .this seal by the consumer.

In the operation of the device shown in Figs. 1 to 5, the handle when in a vertical position closes ,the port 43 to port 44 and thereby seals the liquid within the container I. As the handle is moved forwardly, these ports are put into communication to allow discharge of the liquid from the container I through the faucet 40. As the liquid is drawn from the container and the pressure within the container is reduced, it becomes necessary to supply additional carbon dioxide gas. This is. done by continuing to move the faucet handle forwardly until the cam 3| on the valve plug 32 forces the plunger 30 inwardly to operate the valve pin 29 of the check valve 28 to release additional gas through the port 34 into the container I. The rubber band or check valve 35 prevents liquid from entering the port 34 after the gas ceases to flow therethrough. This admission of gas to container! will build up sufficient pressure therein to again forceliquid from the container. The handle is then brought back to the open position of the valve before again closing thesame which will allow suflicient time to reduce any extreme pressure within the container.

While I have shown and described preferred forms of my invention tobetter illustrate the principles thereof, it is to be understood that other modifications andequivalents are contemplated as will be embraced within the scope of the appended claims.
