ure at least, the advantages presently to be stated. B is the cap or cup which at first fits loosely into the bottle-.neck and is then to be pressed tightly against the glass, so as to shape or mold itself in exact conformity with the surface ofthebottle-neck. For this purpose I may provide mechanism, such as indicated in Figs.4 1 and 4,- wliich consists, essentially, of two heads or disks, the distance between wliich may be varied, and an expansible body-ffor instance, vulcanized rubberheld between said heads. In the specific To al?, 1071/0111, it may concer-7a: i

Be it known that I, EWALD GoLTsTEiN, a subject of the King of Prussia, German Emperor, residing at the city of Cologne, Kingdom of PrussiafEmpire of Germany, have invented certain new and useful Improvements in Bottle-Sealing Mechanisms, of which the following is a specification.

My invention relates to mechanism for sealing bottles, and has for its object to provide improved -means for firmly connecting caps made of metal for other suitable mate- 1 rial with the neck of a bottle or other receptacle. My improvement has for its particular object to press the sides of the cap at every point firmly in contact with the bottle-neck,l so that the cap will conform closely to the eX- act shape of, he neck and mold itself'toallirregularities of the-glass. c'

Another feature of my invention is to provide means for holding or backing the bottleneck against the pressure of the mechanism one of the heads C may be rigidly secured to the stationary frame D, which may be connected" with the bottle-support, while the other head C is'provided with a stenPC2, arrangedV to slide through the 4upper head kC and having a screw-threaded portion C3. The ylatter passes through a bearing D in the frame D and is engaged by a wheel or nut E, therotation of which will draw the lower head C upward, thus` exerting pressure on thel expans'ible body F. Inasmuch as this body is held against expanding up or down by the rigid heads C C, it is compelled tov spread pressing lthe cap B tightly against the inner surface of the bottle-neck and into all irregularities thereof, such as the recess il. The rubber body F practically does not alter its volume, but only its shape, during this operation, and lthusthe cap B is'pressel very forcibly against the bottle. The cap is then very firm-ly held in place, as it does not simply dhere to the glass by friction, but is ac- The invention will be fully described hi-:freinafter and the features of novelty pointed out in the appended claim.

Reference is to be had to the accompanying drawings, in which- Figurel is a sectional elevation showing part of a bottle-neck with av cap in position in connection with mechanism for pressing the cap against the bottle upon the inside. Fig. 2 is a similar view illustrating means for applying a cap on the outside of the bottle. F i 3 is another sectional eletually pressed into locking engagementI with vation showing a iferent mechanism for apall the depressions and irregularities oof the plying a cap to the inside of the bottle-neck. bottle-neck'. The cap therefore cannot be removed bodily and replaced after tents of the bottle have been tampered with; but it becomes necessary to break or tear the cap in order `to open the bottle, and thus protection is secured against fraudulent reitiiling. The cap is held in place very strongly and thus adapted to reliably seal ing carbonated beverages and,the like..

In Fig. 3 the two heads C4 C5 are rigidly connected with each other, being both secured to a st em C, which is hollow, so that it may serveas a pipe for supplying compressed air, oil, or any other suitable medium and has one or more apertures C7 leading into the hollow eXpansible body F. In this construction also the heads-C4 C5 are rigid, so as to prevent4 an upward or downward expan- Fig. 4, is an elevation of a bottle in connection with mechanism, v,such as shown in Fig. 1 with the addition of means for bracing or backing the bottle-neck againstpressure; and Fig; 5 is a sectional elevation of another form of my invention,

Figs. 1,3, and 4 illustrate the application of means of an internal sealing-cap made of suitable sufficiently-yielding material, such as tin, lead, or aluminium. A designates the is a depression, groove, or irregularity formed specially in the manufacture of the bottle; but I desire it to be understood that'tlie inner surface of ordinary bottles almost always shows some irregularities which are suiiicient to secure, in a meas-V tlic conl is bottles containconstruction illustrated by said Figs. 1 and 4 sidiewise or circumferentiully, thus p IOO sion `of the body F and to compel it to IOV spreadperipherally upon inflation.y Thel operation-'of this mechanism will be obvious -Without further explanation,` and the advantagesare the same as above described.

The outwardly-acting pressure is so strong that there is in some cases danger of breaking the bottle-neck.l -To guard kagainst this, I, may employ a rigid or preferably an elastic backing engaging the bottle upon the out-A side, as indicated'atl G in Fig. 4, so that theglass will be backedor braced'againstvthe pressure exerted upon it yon the inside; but

i when the backing G is elastic it iS en aged by rigid surfaces, such as a portion of t e'frame D, SQ that ultimately the thrust exerted by the/.pressure device and transmitted radially through theneck of the bottle is'receivedv by. a: rigid backing. p

may lead from the stem C to the ,interior of =the eXpansible body f, being provided with one or more apertures c withinsaid body.. It will be understood that in this construction each of the pressureexerting devices forms a backing against the action of the other pressure-exerting device, such a mechanism combining two pressure-exerting devices, one acting upon the inside of thebottle and the other upon the 'outside thereof, may also-be employed to apply r'asap on the inside of the bottle, as well as upon the outside, as when the upper portion of the -cap (shown-in Fig. 3) is extended over the mouth of the bottle', as indicated at B2 in' Fig. 5.V In this case as pressure would be exerted inward and out# wardlat the same timefea'ch of the pressing mechanisms would form a bracing device against the action of the other and a` separate backing would be dispensed with.

` While I havedcscribed several formsY of 'my invention with 'considerable detail, I desire it to be understood that in various re spects these constructions may'be modified without 'de arting from the-nature o f my invention as ong as theyembody the features ofthe appended claim. v Idesire it to be distinctly understood that the use of screws for v exerting pressure has been shown only as be- -ing` probably the simplest mechanism for ef'- /N JI fectmg the purpose in view; but I do not wish l to restrict myself to this, and, in fact, I may just as well, or ,even preferably, move one of the heads or both or' distendthe e'xp'ansible -body directly by hydraulic-pressure mechanism, the details of which arefa'miliar to any-A body skllledin theart'. Ineach case the pressure to which the rubber or like expansie..

le body is subjected is very considerable, and the cap Bor B is not only pressedv trans- .versel against the bottleneck, but pulled or p stretc ed lengthwise thereof. -This prevents the formation of folds on the cap.

,-What I consider as m invention,.and de-` sire tosecure by Letters atent, is

A bottle-sealing mechanism, comprising an 'filmer and outer member s aced from each other to rec'elve a bottle-nec between them,

each of' said. members having twol spaced heads or plates forming s aces o env entirely only on the side near t e bott e-neck, the

outer member also' having a backing extendf ing fromthe outeredge of one head to the outer edge ofthe other head, and expansible bodies'located in said s aces, and adapted to 1 er, and therefore to.-
