Application December 5, 1955, Serial No. 550,941

1 Claim. (Cl. 222-416) The present invention relates to improvements in siphons and its principal object is to provide a dispensing siphon arranged in such a manner that, after the first starting operation, desired amounts of liquid may subsequently be withdrawn at desired intervals by the mere opening and closing of a valve.

My siphon is particularly intended for serving liquid over the counter from a relatively large receptacle or container disposed on the counter, the siphon allowing limited amounts to be withdrawn therethrough as the customers call for them and the siphon being so constructed that one starting operation is sufficient to condition the apparatus for subsequent dispensing operation.

A further object of the invention is to provide a siphon of the character described that is sanitary in use and in which the point at which suction is applied is spaced from the point of discharge.

A still further object of the invention is to provide a siphon with a valve structure the fixed of which is formed integral with the siphon tube, while the movable portion is mounted with freedom of limited withdrawal movement for cleaning and flushing operations, the withdrawal movement being limited by a cushion member to guard against breakage, particularly where the siphon is made of glass or similar brittle material.

It is further proposed to arrange the suction means for starting the flow underneath the valve in such a manner that the closing of the valve bars the liquid from the suction tube, while on the other hand liquid sucked into the suction tube automatically discharges with the liquid from the main tube.

Further objects and advantages of my invention will appear as the specification proceeds and the novel features of my invention will be fully defined in the claim attached hereto.

The preferred form of my invention is illustrated in the accompanying drawing, in which Fig. 1 shows a side elevation of my siphon as applied to a container disposed on an elevated platform,

Fig. 2 a fragmentary front view of a portion of the siphon, and

Fig. 3 an axial section through a valve used in my siphon.

While I have shown only the preferred form of my invention, I wish to have it understood that various changes and modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.

Referring to the drawing in detail, my siphon 1 is particularly intended for use in connection with a container 2 disposed on an elevated platform 3 which may represent the top plate of a counter over which the liquid is sold to customers in desired limited quantities.

The siphon tube is preferably made of glass or similar transparent material and is bent in the conventional manner to present a goose neck 4 and two legs 5 and 6 extending downwardly therefrom. The leg 5 is preferably made of a length somewhat in excess of the height 2,774,522 Patented Dec. 18, 1956 ice of the container and is mounted on a cork 7 serving as a closure of the container. When positioned in its proper place the lower end of the leg 5 comes to a point within close proximity to the bottom of the container.

The leg 6 extends downwardly from the goose neck 4 in spaced relation to the leg 5 and at an angle thereto so as to clear the outside of the container. It is somewhat longer than the leg 5 and its lower end projects below the top surface of the counter as shown.

The leg 6 is provided, preferably below the surface of the counter, with a valve 8 comprising a transverse bearing 9 formed integral with the siphon tube and communicating with the passage thereof and a valve stem 10 revolvable in the hearing. The bearing has a conical inner face, as shown at 11 and the valve stem has a similar outer face and has a ground fit with the bearing when in operative position with respect thereto. In the latter position the larger end of the valve stem projects somewhat beyond the bearing as shown and is formed with a handle 12 by means of which the valve stem may be turned.

The valve stem is formed with a transverse passage 13 adapted for lining up with the tube passage when the handle is turned into the proper position while the valve stem closes the tube passage when the handle is turned through a right angle.

The smaller end of the valve stem projects somewhat beyond the bearing and is formed, near its outer end and spaced from the bearing, with an annular groove 14 adapted to receive a cushioning ring 15, preferably made of rubber. This ring allows of partial withdrawal of the valve stem in a lengthwise direction, but limits the withdrawal movement with a cushioning effect. It may be readily removed, when it is desired to withdraw the valve stem altogether.

Below the valve I provide a suction tube 16 which communicates with the tube passage of leg 6 and is preferably formed integral therewith. The suction tube projects from the main tube at a right angle for a short distance, is then bent as at 17 to turn upward in substantially parallel relation to the main tube to a point above the valve, and is then bent again away from the main tube for convenience of access. The upper end of the suction tube is open, and when suction is applied to the upper end, with the valve in open position and with the bottom end of leg 6 closed, liquid may be sucked from the container 2 into the leg 6 to the depth of the valve or to any point desired.

In operation, the filled container is placed on the counter and the siphon is applied in the manner shown. For starting the flow of liquid, the attendant opens the valve 8, closes the bottom end of leg 6, by applying his finger or a cork, and applies suction to the upper end of the suction tube 16, which causes the liquid to rise in the leg 5 and to descend in the leg 6. When the liquid reaches the valve 8, the latter is closed and the suction is discontinued. Now the apparatus is ready for any number of individual dispensing operations by the mere opening and closing of the valve, until the liquid level in the container drops below the bottom end of the leg 5.

If any foreign matter should lodge in the valve passage or around the valve stem the attendant may readily flush the valve stem by pulling outward on the handle. The rubber ring 15 limits and cushions the withdrawal movement and guards against breakage, particularly if the assembly is made of glass. The valve stem may be readily removed for cleaning purposes upon removal of the rubber ring.

I claim:

A siphon of the character described, comprising a tube bent to present a gooseneck and two legs projecting therefrom, one leg being longer than the other one and having a transverse bearing with a conical inner face formed integral therewith so as to communicate with the leg passage, a conical valve stem revolvable in the bearing and having a ground fit therewith and having a transverse passage adapted for lining up with the leg passage when the valve stem is firmly seated in the bearing, a handle at the larger end of the valve stem, the stem having an annular groove in the other end spaced from the bearing, and a cushioning ring mounted in said groove and normally clearing the bearing to allow of partial withdrawal of the valve stem.
