ALVA B. COURT, OF THE UNITED STATES NAVY.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed July 12 1906- Serial No. 325,866.

To all 1077 0771 it may (mince/'11,.-

Be it known that I, ALVA B. COURT, a citizen of the United States and midshipman in the United States Navy, stationed on board United States steamship Pen nsyloan'ia, navyyard, New York city, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertams to make anil' use the same.

This invention relates to improvements in bottles and closures therefor, and especially to that type designated as noi'i-retillable bottles, and the object of which is apparent.

While I do not limit myself to the specific details shown and described, to more l'ully understand the invention, reference is had to the accompanying drawings illustrating a practical embodiment of same, in which like letters designate the same parts in the several views, and in which Figure 1 is a sectional elevation through the top of a portion of the bottle, the closing device being shown in elevation. Fig. 2 is a similar sectional view, the section being taken through the closing device also. Fig. 3 is an enlarged detail view showing the position of the closing device prior to its biing sprung into the bottle neck. Fig. 4 is a sectional view on the line 4 4 of Fig. 1, and F 5 is a section on the line 55 of Fig. 1.

1 designates the bottle neck provided with the annular shoulders 2, 3, and 1.

5 designates a metal plate which rests on the shoulder 3 and may be blown into the glass, the object of which plate, it employed, being that the neck may be severed if acid be used to remove the closing device, the metal plate being of such material as to be affected and disintegrated by an acid as soon as or before the rest of the device and the heat produced by the chemical action, locally applied, causing the ring to expand and crack the thin glass that surrounds the metal ring.

6 designates the annular valve casing which is adapted to seat on the shoulder 2 when sprung into the bottle neck, which valve casing is machined as at 7 to seat the valve 8, which valve is provided with a shank 9 recessed as at 10 to receive the end of a coil spring 11 interposed between the valve stem 9 and the hollow stem 12 of the valve protecting cap 13, the said cap being in the form of a cylindrical cup opening downwardly and mounted to be guided within an annular projection 14 forming an integral extension of the valve casing 6, which extension is slotted as at 1.5.

The lower end of the hollow valve shank 12 is guided by the valve stem 9, which operates therein, and the spring 11 tends to 'lorcc the cap and valve apart, the upward movement of the cap being limited by suitable lugs 16 mounted on the inside face of a split cylinder 17 of resilient material, such as spring metal, and this metal cylinder is provided at one edge with a circumfcrentially extcnfling tongue 18 adapted to normally register with a shallow notch 19 cut in the opposite edge of said cylinder and adapted to also lit an elongated notch 20 so disposed that the spring cylinder may be forced inwardly until its edges touch, when the cylinder will be disposed spirally, as clearly shown in Fig. 3, in which position the spring cylinder may be clamped by means of a wire or cord 21 'litting within a circum'l'erential groove 22. The lower casing 6 is also split, as shown clearly in Figs. 1, 3., and 5, and is preferably provided with a cork gasket 23 which may also extend within the space formed by the adj accnt edges 01 the casing.

In operation, the parts are assembled in the position shown in Fig. 3 with the spring split ring or cylinder contracted, in which position the tongue 1.8 is seated in the slot- 20 so that the spring cylinder is spirally disposed. WVhen thus interlocked, the wire or cord may be secured thcrearound in the groove 22. After the bottle has been tilled, the closure is forced down through the top, it being understood that in the contracted state, the diameter oi the split ring or cylinder 17 is such as to enable its passage ,through the opening at the top of the bottle. After the parts have been fairly started on their way, the string or wire 21. may be cut, and upon further shifting the parts downwardly when the upper edge of the cylinder 17 passes beneath the shoulder 4, the spring member or cylinder will expand into the position shown in Fig. l and interlock the parts in the bottle neck with the tongue 18 disposed opposite the slot 19 so that upon an attempt to contract the cylinder to withdraw the samc, the attempt will be frustrated by the tongue 18 interlocking in the notch .19, and thus prevent the further con traction of the cylinder. It will also be seen that the bore of the bottle neck between the shoulders 2 and 3 is conical so as to insure the entrance of the cork gasket and the subse quent compression of the same to make the valve seat tight.

Vith the parts in their interlocked position, it will be obvious that the cork having been extracted, upon inverting the bottle the valve 8 will be forced outwardly against the compression of the spring 11, and the contents will flow through the lower valve casing out through the slots 15 into the upper cylinder and thence through the outlet of the bottle, but upon the bottle being again set up, the valve 8 will be again seated, the protecting cap 13 at all times preventing any tampering with the valve but allowing of the ready outflow of the liquid when desired.

Having thus described the invention, what I claim is:

1. The combination with a bottle provided With a recessed portion in the neck thereof, of valve mechanism therefor, and means for holding said valve mechanism within said bottle neck, comprising a split resilient ring adapted to be sprung in said recessed portion of said bottle neck above and in operative relation with said valve mechanism, said resilient ring being provided on its respective adjacent edges with a tongue and a nonalined slot su'liiciently deep to receive said tongue and allow the closing of said split ring, substantially as described.

2. The combination with a bottle provided with a recessed portion in the neck thereof, of a valve casing, a valve therefor, a protecting cap for said valve, and means for holding said protecting cap within said bottle neck portion of the bottle and having an upward annular extension provided with outlet slots, a valve seated in said chamber, a split cylinder inclosing said annular extension, a protecting cap operating immediately above said valve within said annular extension and provided with a hollow stem, and a spring interposed between said protecting cap and said valve, substantially as described.

4. The combination with the bottle provided with a recessed portion in the neck thereof, of a valve casing, a valve therefor, a protecting cap for said valve, and means for holding said protecting cap and valve within said bottle neck, comprising a split resilient ring adapted to be sprung in said recessed.

portion of said bottle neck, said split ring he mg provided with inwardly disposed radial p10160b10113 adapted to rest above said protecting cap and said split ring being also provided on its adjacent edges With a tongue and slot, substantially as described.

In testimony whereof, I aflix my signature, in presence of two witnesses.

ALVA B. COURT.
