INVENTORS MOSES RUSENWALD lUDW/K EKES TTORNEY Patented Aug. 29, 1939 SIPHON VALVE STOPPER FOR BOTTLES Moses Rosenwald, Brooklyn, N. Y., and Ludwlk Ekes, Lwow, Poland Application September 22, 1936, Serial No. 101,980 In Poland October 21, 1935 2 Claims.

This invention relates to improvements in siphon valve stoppers for bottles and more particularly to siphon heads employed on bottles for dispensing carbonated or other gas charged liquids.

For many years, siphon heads have been made heads, prior to this invention, have always been fitted with metallic parts, including springs, valve stems, etc. It is believed by many, that gas charged beverages may be subject to contamination from constant contact with the metal of the siphon heads.

Hence a major object of the invention is to overcome all the above and other dimculties and objections and to provide a siphon head made entirely of non-metallic parts and to provide a siphon head which is sanitary, economical to construct, which may be made in various and varied colors and which is attractive and pleasing to the eye as well as being simply and well constructed to perform the functions desired.

Another object resides in the provision in a siphon head, of non-metallic resilient valve closing means, in place of the springs usually used in such heads.

Another feature resides in the provision of means for relieving excess gas pressure from the container or bottle to which the head is applied.

With the above and other objects, features and advantages in mind, the invention resides in the novel combination and arrangement or parts as I shown in the illustrated embodiments of the in- Fig. 3 is a view similar to Figure 1 of a modifled tom of siphon hea'd.

Referring to the drawing in greater detail, the

siphon head is formed of a head or hood 5 of non-metallic material capable of withstanding the chemical attack of CO2. This head, as shown, is formed with thick, sturdy walls to withstand the pressure of the gases in the liquidand also to stand up under continual and ofttlmes careless handling. The head is provided with a discharge nozzle 6, formed with a finger-engaging portion 8 positioned on the opposite side of the head to the nozzle.

It will be noted that the head is formed with a chamber 9 adapted to receive the structural working parts. of the siphon head which are insertable into said chamber from the bottom thereof and adapted to be held in proper working position by the neck lb of abottle or container H as by the usualform of split nut l2.

Within the chamber 9 is preferably placed a pressure plate l3 having a verticalpassage I4 and a lateral passage I5 connecting the passage H with the discharge nozzle 6. To insure'proper alignment of the passages I5 and 6, means such as shown at I6 may be employed to effect a keying engagement between the head and the pressure plate. 0

The bottom of the pressure plate l3 may be 2 provided with a compressible valve seat I! for association with a valve I 8 carried by the push button I9. This button projects through an opening 20 in the head 5 and is provided with 25 a flange 2| for engagement with an abutting shoulder 22 on the head. The flange is provided with'a seat 23 for the reception of the cylindrical neck portion 24 of a hood or domed diaphragm 25. 30

The diaphragm is formed with a flange 28 adapted to be confined between a shoulder 21 in the head 5 and the pressure plate I3. This flange together with neck portion 24 serves to seal the interior of the diaphragm from atmosphere as passed through the opening 20.

The pressure plate is forced against the flange 26 by a sealing ring 28 positioned between it and the bottle neck It and the siphon tube 29 through the medium of its upper bell-like portion 30 and the flange 3| is held in clamped engagement between the sealing ring 28 and the pressure plate I3. 1

From the above it can be seen that the siphon head is capable of quick assembly and disassembly torthe replacement of worn parts and for thorough cleaningand sterilizing; that the diaphragm 25 not only acts to seal the interior of the assembly from leakage but also serves as resilient means for efiecting the return of the valve l8 to seated condition on its seat upon release of the push button It; that excess pressure in the bottle will be relieved by yielding of the valve seat to said excess pressure which may then blow through the passages I4, l5 and 6; and that the structure presents a desirable head capable oi withstanding a considerable amount 01' rough usage.

In siphon bottles, the siphon tube has a propensity to break since it is necessary to remove the head with said tube when filling the bottles. order to aflord more resiliency and hence more resistance to shock and for the purpose of providing a tube capable of more economical replacement, the form of siphon tube shown in Figure 2 may be employed. In this form the tube 29a is shown as separately formed from the bell Illa and connected together as by a preferably flexible sleeve 32.

Should the tube 29a break, it can be readily replaced by another inexpensive glass tube leaving the relatively more expensive bell "a in the head.

In the form of the invention shown in Figure 3, the push button may be replaced by a plunger l9a connected to the valve It. In this form, the diaphragm may be formed as a ringed member 25a having a U-section with the base of the U arranged in a seat 33 in the head 5;

In this form, also, provisions may be made for relieving excess pressure in the bottle ll.

' As shown, a passage 34 is provided in the valve Figure 1 and as can be seen from comparison of these two forms similar results may be obtained although the detailed design of the working parts may be quite different. Therefore, it can be seen that the siphon head may be further varied without efiective departure from the principles of the invention as hereinafter claimed.

From the foregoing it can be readily seen that there has been provided siphon head designs of high eiiiciency and utility; and that the structures have been conceived so they readily lend themselves to be formed entirely of non-metallic parts resistant to CO: or other such gases.

We claim:

1. A siphon comprising a bottle adapted to be filled with carbonic gas-charged liquid, a head removably secured to the neck of said bottle, a dispensing valve in said head, a siphon tube, said siphon tube comprising a portion clamped between said head and said bottle neck, a second portion, and yieldable means for separably connecting said portions.

2. A siphon comprising a bottle adapted to be filled with carbonic gas-charged liquid, a head removably secured to the neck of said bottle, a dispensing valve in said head, a siphon tube, said siphon tube comprising a portion clamped between said head and said bottle neck, a second MOSES ROSENWALD. 35
