Sept. 24, 1935. ROSENBERG 2,01%1555 BOTTLE TAP Filed July 21, 1952 FILL lfi l/777 Mill/"l 3mm; HBYMAN RUSENBERL Patented Sept. 24, 1935 UNITED STATES PATENT oFFrcE 7 This invention relates to improvements in apparatus for facilitating the discharge of liquid from bottles, and more particularly the delivery of carbonated beverages from bottles having the conventional crimped-on form of caps.

Among the objects in view is the production of a valve structure adapted for direct application through a bottle cap without removal of the cap,

pensive, "and effective anchorage of the pene-, trating tube in the material of the conventional bottle cap in a manner to insure a pressure-tight joint therewith, and a still further object is the provision of means for accomplishing this result repeatedly with the sameinexpensive instrumentalities.

With these and further objects in view as will in part hereinafter be stated and in part become apparent, the invention comprises certain novel constructions, combinations, and arrangements of parts as subsequently specified and claimed.

In the accompanying drawing,

Figure 1 is a view in side elevation of an embodiment of the present invention illustrated as applied to a bottle cap, a fragment of the bottle neck being shown.

Figure 2 is a similar view of the same taken -need be delivered at any one time from the bottle as required and the balance preserved under the. bottled pressure for future use; but such previously proposed devices have been of somewhat involved and expensive construction and lacking in dependability for repeated use, and also lacking in capacity for invariably effecting a pressure-tight seal with the bottle cap. The present invention overcomes these difficulties by providing an apparatus of so simple construction as to be of minimum cost, and, in fact, so inexpensive in production as to be available for one time use when required without material loss, and at the same time the device is adapted for many times repeated use with an invariably resultirfg pressure-tight connection with the bottle cap. Also, the size of the organized structure is materially reduced over that of previously known attempts, so that but a minimum space is occu-' pied for packing, shipment, and handling and for accommodation where the bottle is to be inserted in a reduced space, as in a refrigerator,

with the improved valve applied to the bottle cap.-

Referring to the drawing by numerals, I indicates an ordinary carbonated beverage bottle having the usual flange terminus 2 of the bottle neck which is engaged and gripped by the crimps 3 of the conventional crimped-on cap 4. Cap 4 is customarily formed of metal -with an inner liner 5 of cork or other appropriate-sealing material. These parts are all common and well known in the handling of carbonated beverages. The invention itself relates to the means for penetrating the cap 4 to enable controlled withdrawal of the carbonated beverage from within the bottle i,'which means comprises a tubular screw 6, a tap sleeve 1 to which the screw'6 is fixed, a valve 8 for controlling discharge from the sleeve I, an operating thumb button 9 for removing the valve 8 from its seat, an appropriate seat III for the valve 8, and a pressure-retaining gasket ll surrounding the valve'stem I2 which connects valve 8 with thumb button 9. The sleeve 1 is preferably provided with a reduced bore portion 21 for amedial part of the sleeve, and then with enlarged terminal'portions I 3 and I4 leaving annular shoulders l5 and IS. The gasket II is arranged within the enlarged portion l3 and figated against the shoulder l5 and proportioned snugly engage the valve stem i2, allowing the stem to slide longitudinally therethrough, and the valve seat In is arranged in the enlarged portion l4 and rests snugly against the shoulder I8. The valve seat i0 and gasket I I may be formed of appropriately vulcanized rubber, or other available material, adapted to be readily rendered snug-fitting against the valve and valve stem 40 respectively for preventing leakage of pressure or liquid. The valve 8 is normally maintained snugly on its seat by appropriate cushioning means stressing the valve toward its seat, and one form' of such cushioning means may consist of a coiled spring I! surrounding the stem and engaging the inner face of the button 9, and at its opposite and engaging an appropriate plate or washer l8 resting against the outer'face of the gasket I I and surrounding the valve stem I2. Spring I1 is tensloned to appropriately stress the button 9 outward;

The button 9 may be formed on or fixed to the valve stem I! in any of various appropriate ways, but for ease of assemblage, inexpensiveness of 66 production, and absolute assurance of permanence of mounting, 1 preferably employ a device corresponding to the conventional sleeve rivet whose head constitutes the button 6 and whose sleeve is anchored to the stem 12 by being driven onto the threads of a drive pin section l9 formed on and preferably integral with the valve stem l2. The drive pin section I 6 preferably corresponds in construction, material, form, and function with the drive pin set forth in my U. 8. Patent No. 1,482,151, dated January 29, 1924. In other words, the section II is made up of high-pitched thread portions outstanding from the body of the stem 12 and hardened sufficiently for entering metal, such as soft iron or soft steel, substantially without injury to the threads, and the diameter of the section I9 is proportioned to the diameter of the bore of the sleeve rivet, as clearly seen in Figure 4, to cause material of the sleeve to be entered by the threads and to flow down into the valleys between the threads after the manner described in my above-mentioned patent when the sleeve is driven home over the drive pin section l9, and thus an eflective interlock is produced between the button 9 and the valve stem l2. Of course, the valve stem must be properly located in the sleeve 1 with the valve seat l0, gasket ll, plate I8, and spring I1 in place before the sleeve is forced down along the drive.pin section IS.

The screw 6 is generally of the construction, material, form, and function of the screw set forth inmy U. 8. Patent No. 1,411,184, dated March 28, 1922, except that the penetrating or tapered end portion of screw 6 does not require the presence of the thread, though such presence would not be harmful. Thus, the threads of the screw 6 are hardened sufficiently for entering metal, such as soft iron or soft steel, substantially without injury to the threads; but before the hardening operation the screw will have been provided with a passageway or port 20 preferably extending substantially axially within the screw and having a lateral portion 2| opening at the side of the screw at or adjacent the beginning of the tapering end portion of the screw. The sleeve 1. is provided with a lateral opening 22 communicating with the reduced bore 21 and proportioned to receive a drive pin section 23 at the upper end portion of the screw 6. A circumferential flange 24 preferably surrounds the body of the screw 6 at the place of juncture between the drive pin section 23 and the balance ,of the screw. The drive pin section 23 is substantially identical in every respect with the drive pin section l9 above described. except that section 23 may be somewhat shorter and is proportioned with reference to the lateral port 22 to be driven into engagement with the sleeve I, as by hammer blows delivered to the ange l4,-whereby the screw 6 is effectively an- .hored with a pressure-tight anchorage to the sleeve 1. Not only so, but the anchorage of the drive pin section 23 in the sleeve incident to the flowing of the material of the sleeve 1 into the valleys between the ribs or threads of the drive pin section 23 is so effective that the sleeve 1 may be used as a sort of handle with. which the screw 6 may be revolved to insert it or to withdraw it without any danger or likelihood of releasing or loosening of the section 23 in its engagement with the material of the sleeve 1. The degree of permanence of such an anchorage is very great, as

will be apparent from the statn ments setting 5 forth more in detail the facts relating thereto as found in my U. S. Patent No. 1,482,151, dated January 29, 1924.

When the valve and its parts have been properly located in the sleeve 1 and the screw 6 has 10 been anchored thereto as described, the apparatus is complete and ready for operation, but as a substantially disc form overlying the gasket 26 so 20 I as to press the gasket bodily toward the bottle cap when the parts are assembled in operative relation to a bottle.

In applying the valve or tap, the operator merely inserts the penetrating point of screw 6 25 through the cap 4 and then revolves the instrument causing the threads of screw 6 to enter the metal of cap 4 and find anchorage thereto after the manner set forth in my above-mentioned Patent No. 1,411,184, and also after the manner set forth in my U. S. Patent No. 1,299,232, dated April 1, 1919. The thread of screw 6 also finds intimate contact with the cork 5, but the chief anchorage is to the metal 4, and the joint is sufiiciently tight to be non-leaking under all normal conditions. As a means of additional safety, the gasket 26 will preferably be employed and the engagement of the thread of the screw 6 with the bottle cap is sufficiently strong to enable the sleeve 1 and its flange 26 to press the gasket 25 tightly 40 against the bottle cap.

While, of course, the parts may be made of any appropriate material, the sleeve 1 is preferably a die casting without machining. No machining is required in view of the character of the valve seat 45 and gasket and the arrangement of parts provided. All of the parts except the spring, the gasket and valve seat and the screw 6 may be made of aluminum, or other appropriate material. The screw 6 is preferably of iron or steel so as to 60 enable the requisite hardened condition.

What is claimed is:

in bottle tapping valves, the combination of a sleeve having a reduced intermediate portion of its bore and enlarged terminal portions of its 55 bore providing shoulders at the ends of the intermediate portion, valve seat engaging one of said shoulders, a sealing gasket engaging the other shoulder, a valve movably engaging the valve seat, a valve stem carrying the valve and extend- 60 ing through and in pressure-tight engagement with the gasket, a thumb button at the free end of the valve stem, 9. spring between the thumb button and the gasket surrounding the valve stem, and bottle cap penetrating means extend- 65 ing from the sleeve and having a port leading to the said reduced portion of the bore of the sleeve.
