stenen-nnen l Specification of betters Patent.

Application led March 20, i911. Serial No 615,703.

To all whom it may concern Be it known that is, CHARLES DE LUnAosnvrcs, a citizen of the United States, residing at New York, in the`county of New York and State of New York, have invented new andl useful improvements in Siphon-Heads, of which the following is a specification. Y

This' invention relates to vimprmements .in siphon heads and its object is to provide a construction embodying certain 'new details of structure and arrangement for the poses of securing an absolutely tight tlt ot the headupon the bottle, andof preventing any escape of gas through the interstices bef tween the related parts or through the pores of the head.

ln carrying out the foregoing' object. and purposes the invention proposes an improved retaining connection between vthe head and the bottle neck; an improved sealing' `gasket between said head and neck; novel and improved relations between the gasketand the parts appartenant thereto: an improved valve seat construction; and certain other features of detail improvement to be specifically set forth.

A preferred embodiment ot' the invention is illustrated in the accompanying drawings, Where-in- Fin'ure l is a vertical central sect-ion of a Siphon head in accordance with the invena section on the line .Li-n of l; Fig'. 3 shows/in section and in group relation the valve and its appurtenances; Fig. ll is a sectional detail showing' the head construction, the clamping device being' omitted; 5 is a' sectional vien' of the improved sealing gasket; 'Figi'. 6 is a section on the liuc li-B ot' Figi'. Li: Fig. 7 is a sectional detail showing the head iitted with one of the members` ol the clamping" device; and lfig'. S is an enlarged sectional detail showing' the improved valve seat consocket and the top of the neck an improved sealing gaske 6 is litted.

rthe nie-ans ror securing a tight tit of the' hea-d upon the neck embodies a neck ring 7 and a head ri ig 8,' these elements being companions. ln prior const-motions the socket is provided with molded threads and the threaded'nefk ring' engages directly with the threads at" the socket. lVhere the head is of vitreous iaterial, and especially in the case oi" porcelain, the threads in the socket are irregular and frequently, when the neck ring is engaged therewith, the socket is caused to crack. The irregularity or the threads in the. socket is caused by the changes in form incident to baking, and the cracking of the socket is due to the fact that the neck ring', when it is engaged with said threads, Will, on account of 'their irregularities, producc'expansion at different points, the cracking` obviously resulting from such expansion. It will be apparent, therefore, that the irregularity of the thJe-ads, even when the socket does not crack, will prevent an absolutely tight and eliicient connection between the Siphon head and the bottle neck. One of the purposes ot the present improvements is to avoid the objection stated and in carrying out this purpose the companion rings 7 and S aforesaid are employed. The ring 8 is oi. soft metal and is permanently associated with the socket To establish this association the socket has threads 9 originally molded therein which threads are flat, shallow and of considerable extent. The, ring,r 8 is thereupon cast in the socket and its metal fills atented Inlay i3, ittin the spaces between Jthe threads 9 so thatI threads .0 are formed in the outer surface of said ring. which are in exact conformity to and securely grip the threads 9. permanent and strontT intercngagement of the Vthreads 9 and l() is thus established and such irregularities as may occur in the threads 9 are manifestly of advantage in securingr p erinanency between the socket 5 and the ring 8. The latter is provided on'its inner face with .threads l1 which correspond t0 the threads on the ringr 7. lt will be apparent that-the provision of the rings 7 and 8.1n conjunction with the manner of assoclatmg the ring S and thesocket 5 is of decisive advantage in that it. promotes a secure and tinhtfengragemeut ot said socket upon the neck Q.

The gasket is provided with an axial opening 12 and with a circuniscribing fiange 13. The portions of the gasket at each side of the flange are of frusto-conical outline and for convenience may be termed bosses, as such being designated by the numerals 14 and 15 respectively. rilhe upper boss 14 is provided with an annular flange 16 which overhangs the opening 12 and delines a constricted extension 17 of said opening. The si hon tube is indicated by the numeralv 18 mili its upper portion is fitted inthe opening 12. The lower boss-15 fits into the opening of the bottleneck. ThisI opening, as previously Stated, is of fia'ring' outline and consequently the boss 15 is wedged, so to speak, between the inclosed portion of the tube 18 and the adjacent surface of the bottle neck. The boss 15 is, on account of its wedging` tit just referred to, instrumental.insecurely sealing the mouth of the bottle and the flange 13 performs a like function in connection with theupper face of the bottle and the adjacent face of the socket In addition to its function asa positive seal, the gasket 6 has the further function of serving as an elastic and yieldable securing means for the tube 18 which., as stated, has its upper portion fitted inthe opening 12. 1n connection with this latter function the gasket is of advantage in absorbing jars and vibrationsand in thereby preventing the tube 18 from being easily broken.

. The head 4 is provided with an axial duct 19 and with a curved liquid discharge duct 20 extending;r at an angle from the duct 19. Below the duct 19 said head is provided with an axially disposed valve chamber' 21,

and between the valve chamber 21 and the socket 5 with a coniform opening 22 in which the boss 14 conformably seats. The wall of the valve chamber 21 is formed with longitudinal ribs 23 which not only center the valves 24 but bear against the upper face of the boss 14 immediately adjacent the fiange 16 and thereby serve as a substantial reinforcement for the latter, it be ing lunderstood that the purpose of the flange 16 is to prevent u ward displacement ofthe tube 18 and to a ord'an elastic cushion against which the upper end of said tube seats. I

The valve 24 consists'of a cylindrical rubber plug which has a conical seating end and is normally held against a seat 25 formed between the duct 19 and the valve chamber 21 and shown in detail in Fig. 8. The sea't 25 is of conical outline and is pro vided With two or more comparatively sharp annular ribs which sink into the material of the valve and are thus effective, when the valve is in its closed position` to establish an efficient seal against the escape of gas through the duct 19. The valve seat 25 is ribbed because porcelain is porous and its surface is vnot of uniform character. Con- `isequently the provision of the ribs on the The valve 24 is carried by a stem 26l which projects axially through the duct 19 aand beyond the upper end of the head. The

stem 26 is formed at a distance from its lower end with a dished flange 27 against which the valve 24 is tightly held, and below the flange 27 with comparatively sharp threads 28. The threaded portion 28l of the' stem 2G passes through an axial opening 29 in the valve 24. This opening is originally of smaller diameter than the said threaded portion 28 and'` consequently the' latter is utilized to cut its own threads in the opening 29, and to thus provide for a secure fastening Vof the valve. A nut 30 is fitted upon the lower end of the valve stem and adds to the security of the valve.

The stem 26 carries on its upper end a button 31 which works in a recess 32 formed in the upper end of the head 4. Owing to the provision of the ribs on the valve seat 25 it is essential to prevent the valve 24 from turning` and for this purpose the brtton 31 is formed with longitudinal grooves to receive corresponding projections 33 onthe Wall of the recess 32.

The valve 24 is held to its seat by a spring which is fitted in a recess 36 of the button 31 and which bears at one end against said button and at its other end againsta Washer 37. gasket 38 which snugly surrounds the valve stem 26 and is fitted in a reduced coniforin extension of the recess 32, resting on a web or ledge 39 which separates said recess from the duct 1,9 and which is provided With an opening conforming` to the diameter of the' stem 2G and through which said stem passes. The spring 35 is of sufiicient strength to hold the valve 24 firmly to its seat and at the same time to put such pressure on the gasket- 38 as will cause the latter to hug` the valve stem and thereby prevent any Iiras from escaping through the opening in the ledge 39.
