Claims.

The present invention relates to a valve for vessels which are used in aerating liquids.

It more particularly relates to a valve used with a rechargeable syphon bottle'which is used 5 to aerate water with carbon dioxide. The carbon dioxide under high pressure is introduced into the bottle from a small capsule which is associated with the valve when it is desired to aerate the water. The valve will control the admission of the gas to the bottle and at the same time it serves to regulate the discharge of the aerated or charged liquid in the vessel when it is to be used.

Various constructions of valves of this type have been employed in the past but there has always been one great disadvantage attending their use. Whenever they have been used on a syphon bottle there has always been the danger that the bottle or the valve would burst or ex- ,20 plode due to the existence of a high pressure in the vessel. The danger of the vessel bursting has been present particularly when the vessel has been made of a material which could not withstand high pressure, as for instance a glass 5 bottle. This danger of excessive pressure may arise from various causes such as an undisclosed defect in the vessel itself, an overcharge of gas in the capsule, or the presence of too much liquid in the vessel. Obviously this is a danger which 30 must be avoided in order to make the use of the.

syphon bottles safe for the ordinary consumer.

Accordingly, it is an object of this invention to prevent any bursting of the vessel.

It is a further object to provide a means in 3:, the valve which will burst and relieve the excess pressure in the bottle when the pressure rises provision of a disc on the valve which will burst 45 before the vessel can burst, if the pressurein the vessel becomes excessive.

' These and other objects will be apparent upon reference to the following specification of which the drawing is a part and in which like numerals -50 of reference refer to the same parts in each of the' views.

Figure 1 is an elevational view of an embodiment of the invention. Figure 2 is aview in cross section of the valve 55 taken on 8 Plane through the center of the valve and at right angles to the view shown in Figure 1. With reference to Figure 1, the valve l is mounted on the vessel 3 in any appropriate manner. The valve is provided with a spout 5 through which the contents of the bottle are dis- 5 charged after the liquid has been aerated.

Opposite to the spout is the connection 7 to which is attached the holder 9 in which the capsule containing the fluid under pressure is placed when it is desired to aerate the liquid in 10 the vessel 3. The details of the capsule holderv and gas releasing means are not described since they form no separable part of the present invention and are well known in the art.

Referring to Figure 2, the valve consists of the 15 body H which is provided with threads l3 by means of which the valve is attached to the vessel 3. In thebody H is a recess l5 which is designed to overlie the top of the bottle or vessel 3. The bottle usually carries a washer which fits into the recess I! and this insures a tight joint between the valve and the vessel. The body is also provided with a chamber I!) which is terminated at its upper end by a seat 2| surrounding a passage 23 leading from the chamber I9. 25 There is a restricted portion 25 in the passage 23 which serves as a guide for the valve stem 21 which may be longitudinally moved in the passage.

Secured to one end of the stem 21, by the threads 29, is the valve proper 3| which carries a valve facing 33 made of rubber or some other resilient material. By using a material of this nature the contact between the valve proper and the seat is made leakage proof so that none of 35 the excess aerating medium, over that required to aerate the liquid and which is the pressure medium employed to discharge the liquid from the vessel, can escape.

At the opposite end of the stem 21 is a push 40 button 33 which is guided by the walls of the chamber 35 in the body II. Formed on the wall of the chamber 35 are projections 31 which limit the downward movement of the button 33.

.A recess 39 is formed in the upper surface of a portion 40 of the valve body ll projecting within the chamber 35. A resilient rubber gasket 4| closely encompassing the valve stem 21 is received within the recess and serves to make a gas tight joint with the stem. A coiled spring 45 bears at one end against the inner surface of the push button and at the other end on a cupped washer 43 resting on the gasket 45, and encircling the valve stem 21. This spring serves to yieldingly maintain the valve proper 3| in its normally seated position and also to insure a leak.-,

the spout opening W and out through the spout 5. V

In order to prevent the bursting, of the vessel upon development of an excess pressure for any reason whatever a safety device is provided comprising a frangible disc 55 and a sealing gasket 53 secured in position over the outer end of a the cap of the bushing 51 is provided a slot SI.

The slot serves two valuable functions. It serves as a means to remove the bushing when it is desired to replace the frangible disc, by using a' screw driver, coin or other similar object as a tool. It also is the means by which the gas may be relieved into the atmosphere when the frangible disc bursts due to an excessive pressure.

The frangible disc 55 is made of some material which will rupture'at a predetermined pressure. Hence, if the pressure in the bottle should rise to that pressure, the disc will rupture and allow the pressure to fall. It can thus be seen that if the rupturing pressure is carefully chosen the pressure in the bottle can never rise to a point where it would be suflicient to burst the vessel or valve head. Hence all dangers of explosion of any part of the syphon bottle and valve are entirely removed.

With the present construction the disc may be replaced very easily and the vessel may again be used with safety once the dangerous condition has been eliminated.

From theforegoing disclosure it will be apparent that this invention resides in certain principles of construction which may be employed in other physical forms of apparatus without departure. therefrom. It is apparent, therefore, that the form of apparatus illustrated in the drawing for the purpose of disclosure has been given solely in an illustrative sense and not in any limiting sense. The scope of this invention is best defined by the appended claims.
