- MEANS FOR SE-Al lNG BOTTLES.

SPECIFICATION formingpart of Letters Patent No. 743,636, dated November 10, 1903, Application filed December S, 1902. erial No. 138,669. (lie model.)

To all whom it may concern:

Be it known that I, EWALD GOLTSTEIN, of the city of Cologne, in the German Empire,

have invented certain new and useful Improvements in Means for Sealing Bottles, of which the following is a specification.

To this end I provide means for applying a hollow cap externally upon the bottle-neck, the said cap being pressed against the outside of the bottle-neck, which is provided with natural or artificial irregularities, by means of the pressure of a medium, such as india-rubber, which is capable of assuming any shape.

To enable the invention to be fully understood, I will describe it by reference to the accompanying drawings, in which-- Figure 1 illustrates in a sectional view a suitable form of apparatus for carrying out the invention and a suitable bottle-neck, the section being taken on line -1 1 of Fig. 2. Fig. 2 is a sectional plan on line 2 2 of Fig. 1; and Fig. 3 is a view similar to Fig. 1, but showing the parts in a different position with the cap applied to the bottle.

In the particular arrangement shown the india-rnbber has the shape of a ring d, held upon the flange c of the cylinder or ring 6'. An internal cylinder e rests with its lower end upon the upper part of the said ring cl. fis a block, the lower surface of which is provided with a concave recess to receive the hollow cap 0 and is situated within the ring (1 under the upper part of this ring. As clearly shown, the said block f is provided with lateral lugs g g, which pass through slots h 71, formed in the inner cylinder 6 and rest within recesses or a channel 21, provided in the upper part of the cylinder or ring c. A ring or connectionj is screwed upon the outside of the upper end of the said ring or cyl inder c, this connection serving to rigidly hold the blockf in the ring c.

The'device operates as follows: The hollow cap or capsule 0 being placed in position within the rubber ring d or on the top of the bottle-neck with a suitable Washer c for providing ahermetic joint when the cap is pressed down, the bottle-neck is passed into the cap,

and pressure isthen applied to the inner movable cylinder e This first presses the indie-rubber ring d downward, and as the ring 6' is rigidly connected with the block f by means of the connectionj the pressure upon the'india-rubber ring is communicated to the top of the cap 0 through the said block until the packing ring or disk 0' has been fully compressed and can yield no further. The ring or cylinder 6 can then more no farther downward and further pressure upon the cylinder 6 will cause a relative movement between the said cylinder c and the. ring cl, whereby the india-rubber ring at is caused to bulge inward, so as to tightly apply the cap 0 against the sides of the neck of the bottle a, causing it to enter all the inequalities or irregularities therein.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. An apparatus for sealing bottles and the like, comprising a casing, an expansible ring therein, a block rigidly connected with the casing and extending partly within said ring and partly projecting therefrom, and an annular compressor arranged to move between the said projecting portion of the block and the casing and to engage the end surface of said ring.

2. An apparatus for sealing bottles and the like, comprising a casing, an expansible ring therein,'a block rigidly connected with the casing, and an annular compressor surrounding said block and arranged to exert pressure on said expansible ring.

An apparatus for sealing bottles and the like, comprising a casing, an expansilole ring carried thereby, a block rigidly connected with the casing, and a cylinder for exerting pressure on said expansible ring, said cylinder being movable relatively to the block.

4:. An apparatus forsealing bottles and the like, comprising a casing, an expansible ring carried thereby, a block projecting into said expansible ring and provided with means connecting it with the casing, and an annular compressor surrounding the block and'provided with longitudinal slots for the passage of the means which connect the block with carried thereby, a block arranged to enter said expansible ring, and provided with outwardly-extending arms, arranged to engage the space between said block and casing, and the casing, a screwoap for locking said arms an expansible ring arranged to be expanded to the casing and a compressor surrounding by said compressor.
