CLOSURE.

SPECIFICATION forming part of Letters Patent No. 568,486, dated September 29, 1896. Application filed September 27, 1895. Serial No. 563,843. (No model.)

T ctZZ whom it may concern:

Be it known that we, ALBERT S. LAMBERT and EDMUND HOFFMAN, citizens of the United States, residing at Bridgeton, in the county of Cumberland, in the State of New Jersey, have invented a certain new and useful Improvement in Closures, of which the following specification is a true and exact description,reference being had to the accompanying drawings, which form a part thereof.

Our invention relates to the construction of closures or stoppers used for closing bottles, cans, or other receptacles, and has for its object to provide a closure or stopper of cheap simple construction, and which shall combine the elastic principle of the ordinary corkstopper with a positively-locking union between the closure of the bottle or other receptacle to which it is applied.

The nature of our improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which 7 Figure 1 is a central longitudinal section through the neck of a bottle and our stopper applied thereto. Fig. 2 is a plan view of the stopper; Fig. 3, a side elevation thereof, showing in dotted lines the bottle-neck and the cork, which forms a part of the stopper. Fig. 4. is a side elevation of the metallic part of the stopper, taken at right angles to the View shown at Fig. 3. Fig. 5 is a plan view of the blank from which the metallic part of the stopper is formed, and Fig. 6 is a perspective sectional view of a bottle-neck adapted for use with our improved stopper.

A indicates the neck of the bottle, which is formed with two channels A, situated opposite to each other and extending downward to circumferentially-extending channels A the upper part of which, A is preferably made with a downward slant, as indicated.

B is the cork, which may be of any convenient material, such as cork, rubber, or anything else having the same capacity to be compressed and close the mouth of the bottle.

C is the metallic head or cap of the stopper or closure,the central part C of which covers the top of the cork B and is provided with a circular downwardly extending flange C which embraces the upper part of the cork. The curved edge of the flange C is preferably corrugated, as shown, in order to give a'good holding-surface for the fingers. From the lower edge of the flange C extend arms C C the ends of which should bepointed, as shown and bent inward, as indicated at 0 so as to penetrate the substance of the cork.

C C are also downwardly-extending arms from the flange of the cap, and C C are outwardly-bent portions of these arms, preferably formed by bending the metal into a fold, as indicated in Fig. 3, the extreme ends of the arms C being preferably pointed and bent inward, so as to engage the substance of the cork, as is shown at C.

In inserting the closure into the bottle-neck the projecting lugs C are brought to register with the grooves A, and the closure is then thrust down into the bottle-neck until the lugs C come opposite to the circumferential grooves A and by giving the upper side A of the said grooves a downward slant the turning of the stopper can be made to draw the cork still farther downward. .Of course the cork or stopper is removed by turning it until the lugs C can register with the grooves A and then drawing it directly out.

The form of the engaging-grooves A and A may be considerably varied. We have shown the special form illustrated in the drawings as a desirable one; but our present invention is not concerned with the conformation of the bottle-neck, and any form which will provide a groove wherein the lugs C can engage themselves may be used in connection with our closure.

WVe prefer to construct the closure with the metal cap provided with four downwardlyextending arms; but in some cases the arms C may be omitted, the arms C providing a .sufficient union between the cork and capiece. p Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A closure having in combination a cork B and a metal cap C provided with depending arms C the ends 0 of which are bent in arms C the ends of which are folded out to and inserted in the cork, and with depending form lugs O and then in to form anchors C 10 %rms O theJ ends of which are folded out to ALBERT S LAMBERT O1Il1 In "S 5 2. A losure having in combination a cork EDMUND HOB FMAN' B and a metal cap 0 provided with depend- Witnesses: ing arms 0 the ends 0 of which are bent in THOMAS WV. TRENOHARD, and inserted in the cork, and with depending J. XVARD RICHARDSON.
