12 Claims.

in the discharge or dispensing head of a container in a manner that, when the cartridge is opened, gas is discharged into a liquid in the container. Thereafter a discharge control valve is opened to dispense the charged or aerated liquid from the container. In such structures, separate operating means are provided for opening the cartridge and for opening the discharge control valve, necessitating separate manual operation of each of the operating means. 7

Accordingly, an object of the present invention resides in the provision of a discharge head for a siphon or the like which is readily operated to prepare and dispense aerated liquids.

Another object of the invention resides in the provision of a discharge head for a siphon or the like wherein operation of a lever or handle serves the dual function of selectively effecting opening of the gas cartridge and opening of the dispensing or discharge valve.

Further objects of the present invention reside in the provision of a siphon which presents a neat appearance, is of sturdy construction, and inexpensive to manufacture.

Further objects, not specifically enumerated above, will be apparent as the invention is described in greater detail in connection with the accompanying drawing, wherein:

Figure l is a fragmentary sectional elevational view of a siphon embodying my invention; and

Figure 2 is a top plan view thereof.

Referring to the drawing in detail, the siphon comprises a body or receptacle l and a discharge or dispensing head, cap or closure I2. The body If.) is exteriorly screw threaded at M, and the head or closure 12 is interiorly screw threaded at I6, whereby the two may be removably secured to each other. A gasket I8 is mounted in an annular recess I9 in the head to assure a hermetic seal between the head and the body.

The head I2 has a recess 26 screw threaded at its open end to receive the screw threaded end of a siphon tube 22 and has a valve seat 2d at its other end to receive a valve 26, which is adapted for movement in a valve chamber 42. The valve 26 includes a valve disc 3!! of rubber, neoprene or other suitable material provided with a tapered extension 32 which enters the recess 28 when the 00., Inc., Bloomfield,

valve is seated. The valve 28 has an annular groove 38 in its outer wall accommodating a packing 36. A valve stem 38 is screw threaded to the valve 26 at 40, the valve being moved by the stem in the manner hereinafter described. The

= end of the valve chamber opposite the valve seat 2 3 is provided with a bushing it screw threaded in the wall of the chamber 42 and through which the valve stem 38 extends. A compression spring :35 is carried by the valve stem intermediate the valve and the bushing 44 for retaining the valve normally on its seat.

The cap or closure 12 has another recess 59 which is internally screw threaded at 52 for removably receiving a cartridge support 56. support is in the form of a hollow cylinder open at its upper or inner end exteriorly screw threaded at 55 for cooperation with the threads 52 to removably hold the support in place. The other end of the support is closed and is provided with a thumbpiece 58 whereby the same may be readily screwed into and removed from the recess 53.

A gas cartridge fill is carried in the support 5%. The diameter of the cartridge is slightly less than the inner diameter of the support whereby to slightly space the cartridge from the side walls of the support. The contour of the inside of the bottom of the support conforms substantially to that of the cartridge so that when the support is screwed into place the cartridge will be firmly held between the bottom of the support and washer 55 in the recess 55. This cartridge contains a pressure medium such as carbon dioxide and is provided in its neck portion 52, with a sealing disc 64 which is secured therein, by peeping over the edge of the neck as shown at 65.

Means for piercing or puncturing the sealing disc 64 is positioned in the cap E2 in alignment with the sealing disc 54 of the cartridge. This puncturing means includes a plunger H1, one end of which projects beyond the body of the cap and is slidably held in the cap by means of a nut 12. This plungerhas an annular recess 14 for receiving a packing it. The plunger is tapered at its inner end to provide a pointed puncturing or piercing member is. A compression spring 8! surrounds the puncturing member intermediate a shoulder 82 formed in the can and a shoulder 34 formed on the plunger. This spring serves to maintain the puncturing member normally out of contact with the sealing disc 64 of the cartridge to.

A lever St is pivotally mounted at 92 on the cap and comprises a handle 94 and an arm 96. The cap has a depression 98 conforming substan- This tially to the contour and dimensions of the handie 53d whereby to receive the handle when the same is depressed. The arm 98 of the lever is slotted or forked at 109, which fork spans the valve stem 33 and has a tapered recess to accom modate a tapered head E02 integral with the valve stem 38.

As will be seen from the drawing, the handle 94 is longer than the arm 95 and has an enlarged portion intermediate its pivotal point and its free end, to provide greater weight on the handle side of the pivot whereby the handle will fall by gravity. It will also be seen that the handle is retained in spaced relation to the cap by the head m2 of the valve stem. In this way, the lever is retained in neutral or inoperative position and is readily operable.

When it is desired to operate the discharge or dispensing head as herein illustrated and described, the handle as is first raised to move the same in a counterclockwise direction about the pivot 92, thereby bringing the arm 9" into engagement with the projecting end of the plunger '50 and moving the same inwardly. The inward movement of the plunger 19 will cause the puncturing member is to puncture or pierce the disc 6% of the gas cartridge whereby to permit the escape of gas therefrom. The escaping gas travels downwardly in the space provided between the cartridge and the. wall of the support and passes out of the support through openings Hit in the wall thereof into the body of the siphon whereby to aerate the liquid therein.

After the liquid has been aerated, the siphon is ready to dispense the liquid. This is accomplished by depressing the handle t to move the same in a clockwise direction (as viewed) about the pivot 92, thereby lifting the valve stem 38 which raises the valve ZG-off its seat and permits the aerated liquid to be dispensed by way of the, siphon tube 22 and discharge outlet or spout Hi5.

When the desired amount of liquid has been dispensed, the handle is released, whereupon the spring dd, which was placed under tension when the handle was depressed, will return the valve to its seat and the handle to its normal position, whereby to close and seal the discharge outlet.

After the cartridge has been discharged and the liquid aerated in the aforesaid manner, it is not necessary in further dispensing the liquid to again raise the handle, it merely being neces sary to depress the handle to unseat the discharge control valve.

When all the liquid has been dispensed, and it is desired to recharge the siphon, the cap 12 may be unscrewed from the body, the cartridge sup port unscrewed from the inside of the cap, the used cartridge replaced by a new one, a new supply of liquid placed in the container and the cap replaced on the body, whereupon the siphon is again ready for use.

As will be'seen from the foregoing, the present invention provides a siphon or liquid dispenser which is readily operable to prepare and dispense charged or aerated liquids and which is operated by simple manipulation of a single lever.

As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.

It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
