CAPSU LE-BOTTLE TOP.

SPECIFICATION forming part of Letters Patent No. 661,836, dated November 13, 1900.

Application filed April 12, 1900.

To (I/ZZ whom, it may concern:

Be it known that I, FRANK A. WILMoT,a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connectiout, have invented a new and useful Capsule- Bottle Top, of which the following is a specification.

My invention relates to a class of bottles which I term for convenience capsule-bottles-that is, bottles used for aerating beverages by means of sparklets or capsules charged with carbon dioxid or other gas; and my invention has for its object to provide a bottle-top-that is, the metallic cover which is rigidly secured to the neck of the bottle and is provided with means for holding the capsule securely while the cap is perforated and the gas let out and which also holds the gas so that it cannot escape and the water or other beverage contained in the bottle must become charged therewithwhich shall be made entirely from sheet metal and the parts of which shall be made wholly'by presswork and by simple and inexpensive operations and shall be so constructed that they may be assembled and secured together in a manner that will secure durability and a degree of strength far in excess of the greatest possible requirements and at a minimum expense.

With these ends in view I have devised the novel capsulebottle top which I will now describe, referring to the accompanying drawings, forming part of this specification, and using reference characters to designate the several parts.

Figure 1 is an elevation of my novel bottletop detached, and Fig. 2 is a central vertical section thereof.

A denotes the gas-chamber, which isusually approximately spherical in shape and is made of two pieces of sheet metal secured together by a joint 10. Below the gas-chamber is a neck 13, and below the neck is a base G, which is adapted for attachment, ordinarily by screw-threads,to a bottle-neck. (Not shown in the drawings.) My invention lies in the construction of the base and in the attachment of the gas-chamber to the base at the neck. The metallic parts below the gas-chamber are Serial No. 12,598. illo model.)

three in numberviz., the outer shell 61 of the base, the inner shell 9 of the base, and the locking-tube f. The upper edge of shell (1 abuts against the lower edge of the gaschamber at the neck, the joint being indito engage a corresponding screw-thread (not shown) on the bottle-neck. It will of course be understood that the special contour-i. 6.,

the design-ofeither the gas-chamber, the

neck, or the base is not of the essence of my invention, but may be Varied to any extent without departing from the principle of my invention. The inner shell in practice follows the contour of the outer shell, excepting, of course, that the inner shell is threaded and is provided at its upper end with a downwardlyturned flange 15, whereby a pocket 16 is formed to receive a gasket or other packing 17. The locking-tube f is shown as extending through the neck and upward into the gas-chamber and downward parallel with flange 15. The upper end of the lockingtube is upset-7I. 6., flared outward above 'joint 11, as at 18-so as to form a tight joint with the wall of the gas-chamber, and is again upset or flared outward below joint 11, as at 19, so as to form a tight joint with the upper end of the base. The neck is preferably a concave curve, as shown in the drawings, and the locking-tube between upset portions l8 and 19 is caused to conform closely to the 1 curvature of the neck, so as to make a tight joint between the parts. Below upset portion 19 of the tube is a straight portion 20,

which lies closely in engagement with down-- comprising a gas-chamber and a base, said base consisting of inner and outer shells and and below theirpoint of intersection.

2. A bottle-top of the character described comprising a gaschamber and a base, said base consisting of an outer shell having a flange 12 and an inner shell whose lower end is curved about said flange whereby a bead 13 is formed, the base and gas-chamber being secured together by a locking-tube which is upsetabove and below their point of intersection. v 1

3. A bottle-top of the character described comprising a gas-chamber and a base, said base consisting of an outer shell having a flange 12 and an inner shell-whose lower end iscurved about said flange whereby a bead 13 is formed and whose upper end is provided witha flange 15, the base and gas-chamber being secured together by a locking-tube which is upset above and below their. point of intersection and lies in contact with flange l5.

4. A bottle-top of the character described comprising a gas-chamber and a base, said base consisting of an outer shell and an in ner shell secured together at their lower ends by a bead, the upper end of said inner shell having a downwardly-turned flange whereby a pocket 16 is formed and the base and gaschamber being secured together by a lockingtube which is upset above and below their point of intersection and whose lower end lies in contact with the flange upon the inner tube.

5. A bottle-top of the character described comprising a gas-chamber, a neck and a base, said base consisting of inner and outer shells and said neck consisting of the abutting ends of the gas=chamber and the outer shell and a locking-tube lying within said abutting ends and upset both above and below their point of intersection.

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

FRANK A. WILMOT;
