the'ldrawings accompanyingand forming a 'partof i this specification' I- showseveral fdifierent articles provided Withhermetic sealing means involving my invention; but I do I not limit myself' to the disclosure thus made,

'for certain variations may be adopted within the scopeof the claims succeeding the descriptionhereina'fter'made ofsaid sealing means.

*The invention includes as 'one of its features: aHrecep-tacle having a seal-seat and means for holding the sealseat permanently in place, combined-Withaseal and solder for holding" the' seal onits seat and fusible. "The seal, as will: hereinafter appear, 'is puncturwablej in ord'er toefiect the removalof the contents of: thereceptacle, and when the contents-0t therecepta'cle :have been Withdrawn the Y seal can be' 'removed by :heat applied to the soldenand-the'heat may be either that-of 'vbdilingwater :ora smokeless flame but these =are1points upon which no particularireliance ris placed, except: thatizthe seal is held relatively permanently in place 'bya fusible solder. .i'l-he seal seat may be of 1 any desirable eharaeteretor example -in theform of a metal 'ringyeither cast o'nto' the receptacle ;ce1nentedit-hereto or embedded into the receptacle :mass. emplo'ying a cast me tallic sealseat I inter-pose between theseatand the recepta- 'ele a'yieldable mediumyso thatwhen the said mast-metal seat ,w Whichis usually made in the form of: a 1band, shninks the'receptacle; provided thesame' be of glass or'equivalent materiahvcannotwbe -f-1'acturedor broken; This yieldable medium between the castseahand the receptacle maybe of: any 'desirable character; a heat-resisting medium, suhhasasbestos, being :quitesatisfactoryfor the purpose.

As will be understood from the foregoing statements, the invention ineludes a seal-seat and a seal, theformer of which may be'co'nne'cted to the receptacle in any desirable way. The=seal seat represented in- Fig. 1 his "of annular form and is'denote'd by 3. Said-seal-sea t'3 is cast to or upon the bottle-neck. "Infinishingsaid neck I; form, near" the upper e'dge thereof; interiorly and exteriorly;annu1ar'grooves;=as; and 5 respectively,whichmay beof any desirable cross-sectional shape but" Whichate illustrated as of -V form in I eross-section,--so that the metal Which is to form said annular seat can enter the-'grooves in order to:secure :a "permanent and interlocked relation -between the cast seal seatka-ndithe' bottle-neck. Prior to casting the oireular =-seal 1 seat or molding it onto the bottle Ii place in' -i'thev two grooves l and 5' nin'gs, as fi -arid} 7 of some yieldable 1 and preferablyhheat resisting m aterial. J These rings- 6=and=' Twill-snugly fit the grooves and L theiru'pperFedges will overlie the-upper edge of thebottle neck. When the two rings 6 =arid 7 are fitted in place, Lean cast theseal seat to -the bottle. By reason of the interposition of the yieldable substance between the cast metallic: seal seat aridfi the bottle-neck there is vno possibility-When the seal seat shm'nks' or -oontracts in 'cabling ef cracking-or fracturing'the bottle.

I The material :ofwhich" the two' ringsfi and 7 is composed is preferably-of: a heat resisting or: non-conductingcharacten and li find asbestos to be satisfactory for this purpose, by virtue of which when I; pour the hat molten metal into the seal-seat' forming anol ds such hot metal cannotfuse the-glass of which the :bottle' iscomposed owing "to the interposition of the non-conductors of heat between the parts. The cast seal-seat 3 has its upper side rounded to prevent the'presence of objectionable sharp edges, and the seal 8 rests trally over the seat therefor.

on the up er side of the seat. In the case of beer-bott es the seal 8 will be preferably made of tin and will be readily puncturable, so that when it is permanently united with the seal-seat a sharp instrument can be projected through it to permit, the withdrawal of the contents of the bottle. The seal is of disk form and is concaved or dished in its upper side to receive the convex end of a holding-tool which holds the disk or seal cell- The seal is illustrated 'as of concavo-convex form and as having a slight straight or flat marginal portion which is directly sustained upon the annular seat or band 3. When the seal 8 is positioned on the band after the bottle, of which the neck 2 forms a part, is filled, the seal will be relatively permanently united to its seat by means of a solder which is readily fusible. Ifind that a solder for this purpose can'be satisfactorily made of a composition of pure km, cadmium, and bismuth.

' der will of course withstand great pressure, .and yet will readily melt, for example, at a point below the boiling-point.

It will therefore be understood that after the contents of --the bottle have been removed by puncturing the seal 8 said seal can be easily removed by dipping the bottle-neck into boiling water or passing it through a flame. The metallic solder, therefore, which unites the seal and its seat is consequently more readily fusible than either the seat or the receptacle, so that when the seal is removed by heat there is no possibility of fusing either the seat or the bottle or the means which hold the two latter parts in permanent relation.

In-Fig. 2 the neck of the bottle is indicated by 2 and the seal-seat by 3. In the outer side of the bottle, near the upper edge there .of, Iform during the process of manufacture of the bottle-neck an annular rabbet or groove 9, into which-what might be considered the lower edge of the annular seat is placed, cement of a suitable character having been put into the annular rabbet or groove.

embrace the to of the neck, the outer flange, as will be un erstood, being fitted and cemented into an external annular groove in the neck, so that the annular seal-seat or band will be permanently held in place. The cement is one that cannot be attacked by the heat employed in removing the solder which holds the seal 8 relatively ermanently to its seat 3". The seal 8 is he (I to the seat 5 by fusible solder exactly as is the case with the seal 8. It will be understood that in the case of both seals, they bein of concavoconvex form in cross-section, t hey fit within the u per open side of the annular seat, so as to ai the solder in holding the same in place.

In Fig. 3 I show another means of securing the seat to the bottle-neck, the latter being designated by 2 and the former by 3". Both annular seal-seats 3 and 3 can be secured in place by spinning. The cross-sectional form of the seat 3* is practically the same as that of the seat 3 The seat 3", however, is applied to the bottle-neck while the latter is in a plastic condition, by virtue of which the inner depending flange of the seat 3 when lateral pressure is applied thereto can be embedded or pressed into the semiplastic mass of which the neck is com )osed. In the outer flange of the seat 3 form perforations, as 10, corrugations, as 1.1, and notches,

as 12. The semiplastic bottle mass will be t C 0 "MW lrWt llll mar 11 o .10 pm It mils, alugtmt, and notches, so that when the bottle is cold the stock of which the same is composed will be embedded firmly and permanently in the seal-seat, so as to anchor the latter firmly in place and prevent it from motion in any direction. In fact, the two parts when assembled present a structure that is equal in strength to an integral one.

In applying the seal-seat 3 to the bottleneck this is done when the mouth of the neck is being tooled to a finish, the glass at this time being in a comparatively soft condition, so that it can be pressed into the roughened portion of the seat, composed of the perforations, corrugations, and notches. The seal 8 applied to its seat 3 is the same as the seals 8 and 8 and is united to its seat in the same way that the other seals are connected with their seats.

The seal-seat and seal may be of any desired material, either tinned iron, German silver, or other metal that will withstand the temperature to which the vessel is subjected shape, although in the form illustrated the seal-seat has two depending flanges, between which the upper edge of the bottle is firmly gripped, so that when the seal is soldered thereon a perfectly air-tight seal for the bottle is provided.

While I have described the seal-seat 3 as united with a glass bottle, a part of the bottle being embedded in the seal, and vice versa, this is not essential, for the receptacle might be of earthenware, in which case the plastic mass would be embedded in the seal and the latter in turn embedded in the plastic mass, following which the earthenware receptacle posed into the neck of the bottle.

ent, is

would be baked, and when baked it will be found that the seal when thus united to the earthenware receptacle will be immovably secured in position.

In applying the solder to the seal in the different forms it will be apparent'that the same is simply applied to the marginal portion of the seal, and by virtue of the relation of the latter and its seat there is no possibility ofthe solder entering the vessel. The sealing means is simple and economical, and it is found that a large number of receptacles can be sealed in a short s ace of time.

It will be understood t at the disks or seals are not removed to pour out the contents of the receptacle, but are simply punctured with a sharp instrument, which spreads the material of which the disks or seals are com- When the bottle is returned to the factary with the punctured disk thereon, the latter will be removed by passing the bottle-neck through boilincg water or through a smokeless flame in or er to secure the quick and readydetachment of the seal. Following this, the bottle-neck and seal-seat are cleaned and the bottle filled and sealed. The seal when removed is not thrown away, but can be remelted for further use.

In the case of the several seats they present each depending flanges which grip between them the bottle or receptacle neck. The outer faces of these flanges are flush with the corresponding surface of the bottle or receptacle neck in each case, so as to avoid recesses in which dirt mi ht lodge.

Having thus describe my invention, what I claim, and desire to secure by Letters Pat- 1. A receptacle having a seal-seat provided with depending flanges tightly gripping the receptacle on the inner and outer surfaces at the neck thereof, combined with a seal, and fusible solder for holdin the seal onto its seat to hermetically seal t e receptacle.

2. A receptacle having a metallic seal-seat,

combined with a seal having a marginal flat portion to rest on the seat and an intermediate concavo-convex portion, the concave surface be1ng up, and fuslble solder on the seat,

overlying the upper surface of the seal along,

the margin thereof.

3. A receptacle having av metallic seal-seat cast thereon, and a yieldable heat-resisting medium between the seat and receptacle.

4. A receptacle havinga metallic seal-seat cast thereon, and an asbestos packing between the seat and reeptacle.

5. A receptacle having a neck, provided interiorly and exteriorly with annular grooves, a cast metallic seal-seat adapted to enter the grooves, and a yieldable medium in the grooves between the seat and neck.

-6. A receptacle having a seal-seat permanently connected therewith, combined with a concavo-convex seal, the concaved side being uppermost, said seal being supported upon the seat, and fusible solder applied to the marginal portion of the seal on the upper surface thereof for uniting it with its seat and upon said seat and constituting a seal, and

fusible solder on the upper side of the seat,

overlying the mar inal portion of the disk.

In testimony w ereof I have hereunto set my'hand in presence of two subscribing witnesses.

DAVID GENESE.
