-Re'ferring to tl'ie -'='drawin'gs in detail a base designated generally tlcompiises a relatively stifi strip of metal Hprovidedadjacent-opposite ends with openings I 4. Opposite" ends of the stripor base i 'f 2 are *p'roviiied with downwardly inclined extensions 'I 'S terminating at their outer lower ends in clips 18 which'are adapted to engage over the bead'B o'ia conventionalljuicecontaining'can which is equipped with a" conventional topT.

Extending through theopenin'gs l4 in the base or strip 12' aretubesZB-and' '22,the upperends of which "are externally s'crew "threaded as "at 24 and 25 respectively for'a'purpose'to be more fully hereinafter described. Threadedonto the threaded end "24 0f thetube 20"are clampin nuts 28 whicheneage oppositesides'of the strip or "base T2,"finniytdciampthe tube '20 in position onthe 'stripor'base. Similar clampnuts 30Jare threaded 'ontothethreads'26' ofthe'tube'22 to engage op- 'po's'ite'sidesiofthe'strip or'base l2, to hold the tube"22i'in spaced p'ar'alIeL relation to the tube-"20. A suitable sealing gasket '32 surrounds each tube '20 and 22., and when" the device is onfplace on the top T of aIcanC as"illustrated inFigur-e '2, these sealing .gask'e'ts form' a fluid tight (seal at the junctions of the tubes 29 and 22 with the .top T. The end of each tube 20 an'd'22 iremote'from the threaded end'si zl and "25 thereof respectively are bevelled as iat"34 to' form Ls'harp cutting edges .on the tubes whieh will effectively punch through the t0.pT of'the can C. -Itis to be noted that the in- 'clinationof the'bevelled. portion 34 is outwardly toward the wan-or the :caniC so'that-the punched out portions 1.? will" be turned inwardly on the side of the.openingsIformed-by the-forcing of the respectivetubes'iill-and 2'2- throughthe top T nearest. the sidewall of thecan C.

Threaded onto-the upper threaded'erid 240i the tube is the neck 36 of -afpumpcylinder" 38 containing atpiston .40 which, is connected to a piston rod 14% operating through anaxial opening-i-n thelhead ikof thecylindert-B. The end of the piston. rod J12 remote-from the piston :49 is equipped-with a.-hand1e 46,fland surrounding the.,-.piston rod z and bearing at one end onthe head M and at its oppositeend on the handle 46 is "a "compression, coil1spi ingl8, which vyi'eIdingI-y uit'gestheinis'ton d0 toward the-head E4.

Threaded "into the "internally threaded neck '36 of the 'c lmuer'sais a valve caged!) which is'provide'djwith'amaxialfpassagei52 which opens iTl't0"the"bliifdr idflwhilefihe 'dppfisite end the passage opens into a chamber 54 formed in the cage 50, and contains a ball valve 56. Formed at the end of the cage 56 remote from the passage 52 is an inturned lip 58 supporting one end of a compression coil spring 60, the opposite end of which bears against the ball 56 to hold it upwardly in passage closing position as will be readily understood upon reference to Figure 2. It will thus be seen that as the piston 46 is advanced toward the valve cage 50 against the effort of the spring 48 air within the cylinder will be forced outwardly through the passage 52 and into the tube 20 to be discharged through the bottom thereof into the liquid L within the can C.

As illustrated in Figure 2, the tube 22 is provided with a port 62 which opens into the can C above the level of the liquid L contained therein, and rotatably mounted within the upper end of the tube 22 is the end 64 of a discharge spout 66. An extension 68 is formed at the inner end of the portion 64 of the discharge'spout, and in one position is adapted to overlie the port 62 to effectively seal it against the escape of air. As illustrated in Figure 2 the discharge spout 66 is provided with an inclined shoulder 16, and threaded onto the threaded end 26 of the tube 22 is a bushing 72 having an inclined surface 14 which engages the shoulder to hold the spout 62 in proper position in the tube 22. A suitable sealing gasket 76 is seated on the end of the tube adjacent the threads 26 and contacts the extension 64 and bushing 12 effectively to seal the parts against the escape of liquid. A suitable handle 18 is mounted on the base or cross bar I2 to provide convenient means for manipulating the device.

In the modified form of the invention illustrated in Figure 5, the upper end of the tube 26 instead of being equipped with the cylinder 38 is provided with a cylinder 86 having an internally screw threaded reduced neck 82 for engagement with the tube 26, and mounted for reciprocation within the cylinder 86 is a conventional piston 84 having a piston rod 86 which operates through the cylinder head 88 of the cylinder 66 and is connected to the armature 90 of a conventional vibrator 92 housed within a housing 54 which is provided adjacent its bottom with laterally extending flanges 96 for entrance into the grooves 93 formed in channels I66 which are fixed to the base In in place of the handle H3. The vibrator 92 is of conventional electro-magnetic type and has connected thereto a conventional conductor cable or cord I62 which is equipped with a conventional attachment plug 164 so that when the plug is entered into a suitable convenience outlet, the vibrator 92 will be set into operation to caus the armature 96 to reciprocate and reciprocate the piston 84 within the cylinder 80. The neck 82 is equipped with a conventional check valve such as that previously described to assure the introduction of air into the tube when the armature 90 vibrates.

In use it will be understood that the tubes 26 and 22 are forced through the can top T as illustrated in Figure 2 so that their lower ends ter-. minate near the bottom of the can C. Upon reciprocating the piston 46, or the piston 84 within its respective cylinder, air will be introduced into the can through the tube to bubble up through the liquid L contained within the can C into the space in the can above the liquid. When aeration is the only operation to be performed the spout 66 is rotated about the longitudinal axis of the tube 22 so that the air above the liquid L may escape through the port 62, and the aeration may take place for any length of time desired. When it is desired to dispense the liquid from the can however, the spout 66 is rotated about the axis of the tube 22 so that the tongue 68 overlies the port 62, effectively preventing the escape of air therethrough, and upon reciprocating the piston 46 or 84 as the case may be within its respective pump cylinder, the air will be forced through the tube 26 and will find its way into the space within the can C above the level of the liquid, to create a pressure head on said liquid and force it out through the tube 22 and spout 66 into a suitable receptacle.

While in the foregoin there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
