To all whom it may concern:

Be it known that I, ROBERT HUNTER CAMPBELL, a subject of the Kin of Great Britain and Ireland, of Angel Road, Ed-

' nionton, in the county of Middlesex, England, have invented new and useful Imspace,

provements in Capsules or Containers for Compressed or Liquefied Gases, of which the following is a specification.

This invention relates to capsules, or containers, for compressed, or liquefied, gases, which capsules, or containers, are closed by adevicewhich has to be perforated when gas isto be released from the capsules, or

containers,and the objectofthis invention is toprovide means whereby the closure is edccted in a very ready, economical and ellicient way and so also that when it is de sired to re-use the capsules, or containers,

the perforated closing device can be readily removed and a new one be put in place for closin the capsule, or container, after it is rec arged-with compressed, or liquefied,

The inside of the neck of the capsule, or container, to which thisinvention is ap plied is formed with an annular groove, or

pierced, and provided with projections, or

grooves, and being of a diameter which will allow. of its being inserted into the neck otthe capsule, or container, so as to rest upon the lower, or inner, surface; or

boundary, of the annular groove, or space,

a passage, or passages,'being left for the admission of gas in charging.

According to this invention the edge of the said disk, or piece, is formed, or thick ened, or an additional ring is, or additional rings are, provided, so that, when, after char ing, pressure, in the direction of the lengt of the capsule, or container, is exerted upon the said disk, orpiece, or upon its edge, or upon the additional ring, or rings, the said disk, or -piece, is pressed which can be cutin the metal of the neck itself, or in a piece fixed thereto, or be.

upon the seat (formed by the lower,sur-' face, or boundaryiof the groove, or space,). and the n ietal of its edge, or the metal of the additional ring, or rings, is displaced,

causing the solid metal to spread, flow, or

squirt, inward, and outward, sidewise, so as to enter, and be firmly held in, "the said annular groove, or space, and in conjunction withthesaid disk, or piece, efiect a tight closure of the capsule, or container.

ljhe annular groove, or space, may be plain, or may, if desired, be undercut, or formed in any way. so as to properly receive, and hold, the metal which has been displaced and caused to spread, flow, or squirt, as aforesaid, and hold the disk, or piece, in position to, form a tight closure of the capsule, or container. The gas can be admitted, from the charging machine, at

the top oft-he neck as usual, or it can be admitted by an opening at the side of the neck leading .into the groove, or space, so

that the said opening is closed by the'm'e'tal which fixes the closing piece, or disk, in

position.

The accompanying drawings represent,

in vertical sections, various ways in which.

thisinvention can be performed.

Figures 1 and 2 show the neck of a capsule in which the metal to be forced into the groove, 'or space, is part of the closing disk,, or piece, itself. Figs. 3 and 4 show the neck of a capsule in which the metal to be forced into the groove, or space, is separate from the closing disk, or piece. Figs. 5 and 6 are respectively vertical section and broken side elevations of a. cap sule showing another modification Fig. 7

is a plan of the annulus 6 of this modification; Fig, 8 iswa broken side elevation of another form of capsule with a modified form of the closure, the latter shown at one end closed and the other end in position for charging; Figs. '9 and 10; '11 and 12, 18 and 14: are vertical sections of a capsule neck showing different modifications of the closure device in charging and sealed positions respectively; and Fig..l5 is a modified form of the sealed cap shown in Fig. 14.

In the several figures the neck of the con. tainer, orjcapsule, is "marked 1, the closing "disk, or piece is marked 2, the groove, or

space, to receive the securing metal 18 marked 3 and the seat, against which the said'disk, or piece, makes a closure, is marked 4 and the metal which is pressed into the groove, ofospace, 3 is marked 5.

edge, this metal constituting the metal which is to be pressed into the groove 3.

-Fig.'1 shows the parts as arranged before charging, and Fig. 2 shows the disk secured,

in 1ts closing position by forcing the metal of its thickened edge into the groove 3. The thickened edge of the disk 2 is formed, or

" perforated, to constitute a passage, or passages, for the gas in charging, this assage,

or these passages, being closed w on the pressure is put on the edge of the disk to close the capsule. v

In Figs. 3 and 4 the groove is shown made as in Figs. 1 and 2, but the metal 5, which is to be pressed into the groove 3, is separate from the disk 2. Fig. 3 shows the parts in'the'position before charging and Fig. 4 shows the capsule closed.

Figsf5 and 6 show, respectively in the position for charging and in the closed condition, a capsule with an ordinary recessed neck, the seating for the disk 2, being formed ona hard metal annulus 6, resting on'the ledge 7 of the recess, in the neck and having a portion 15 projecting into the neck below the said'ledge 7, the upper part of the neck being turned over to form the upper part of the groove, or recess, to receive the securing mietal 5.

Fig.-7 ,shows the annulus 6, separately, the nick '8, being formed in it for thepassage of'thegas in charging.

Fig. 8 shows a similar arrangement applied to a container with a closure at each end, the parts being shown, at the upper end, in the .position for charging and, at the lower end, in the closed position. In this case the annulus 6 is shown as beingwithout a portion projecting into the neck below the ledge 7 asin Figs. 5 and 6.

Figs. 9 and 10 show a like arrangement, but with the seat 4, formed around the end of the neck and with the groove, or space, 3, for the securing of metal 5, formed by a piece '9, screwed onto'the neck.

j Figs. 11 and'12'show a similar arrangement but with the piece 9 secured to the capsule by turning down, over the led e 12 on the piece 9, a flange 13, which, an the seat 4, can be formed by cutting a groove in the end of the neck. In these figures the metal piece 5 is made with a recess 14, to receive the disk 2, which is made cup-shaped and the gas, in charging, passes through grooves in the side of the piece 5 and through a slot in the sides of the cup-shaped disk.

Figs. 13, 14, and 15 show an arrangement wherein the metal to form the closing piece 2, and the metal to be forced into the groove,

or space, 3, are made in one, the metal being pressed (as shown in Fig. 14) so as to spread into the groove, or space, 3, thedisk, or

portion, 2, to be pierced being formed by displacing or turning out, some ofthe metal, as shown in Fig.- 15. The ways for gas in charging are indicated in the various ar-' rangements at 10. The closing disk, or piece, 2, is made so that it will allow the gas to pass in charging, for example, it may be made with a corrugatededge, or with projections, or be otherwise formed to afford passages, these being closed when the disk, or piece, is pressed onto its seat on forcing the metal 5, into the space 3.

In the various arrangements illustrated, the part which forms the seat 4,'is of smaller diameter than the upper margin of the groove, or space, 3, so as to allow of the introduction of the closing disk, or piece, and the securing metal 5. The metal 5, can be pressed into the groove, or space, 3, by any suitable arrangement of. the charging plunger of the charging machine, for instance, by making the said plunger with a part corresponding in shape and area, with the upper surface of the metal 5, andindependently movable relatively to the other part, or parts of the plunger, so that the metal 5, can be acted upon by the said movable part to effect theclosure while the other part, or parts, remain in position to bear on the container, or capsule, and, wherev In Figs. 13, 14, and 15, there is indicated,

in dotted lines, at 11, a side passa e which, in either arrangement, can be use for ad- .mitting gas in charging, instead of forming passages in the metal piece 5.

Variousother modifications of the device which do not depart from my invention will readily suggest themselves and I do not limit myself to those specifically shown. In the followin claims when I speak of a recessed neck I use the expression in a sense broad enough to include all the modifications shownviz. whether the recess be formed by an offset in the metalof the capsule neck pro er as in Figs. 1 and 2, or a recess formed etween an independent annu- Ins and the inner face of the neck as in Figs. 5 and 6 or between an external sleeve and the outer face of the neck as Figs. 9-10 Similarly whenI speak of a seat for the closure disk I usethe expression in a sense broad enough to include'the various forms shown-w hether the seat be formed upon 14 and 15) or independent thereof, as in the remaining figures. 7

/Vith these explanations I claim as my invention 1. A. capsule for compressed gas, havinga neck with internal lateral recess through which the gas passes duringv filling, a perforable disk closure for the discharge pas- 1 sage in said neck, and a crushable filling and retaining member above the disk and recessed to afiorda fill passage adapted to be crush d into said lateral recess to close the same and to force saiddiskclosure to its seat and retain the same in itscldsure position. I

2. A capsule for compressed gas,'having a 30 discharge passage in said neck, and a crushable filling and retaining member above the disk andrec'essed to afi'ord. a fill passage adapted to be crushed into said lat eral recess to close the same and to force said disk closure to its seat and retain the same in its closure position. A

4. A capsule for compressed as, having a discharge outlet, aperforable disk closure therefor, and crushable means above the disk for closing said fill passage and holding said closure disk to its seat after the capsule has been filled, said .c'rushable means being recessed to afiord a fill passage, substantially as described.

5. A capsule for compressed gas, having a neck internally undercut at its ri id upper edge, a closure disk, a seat for t e closure disk and a closure ring of soft metal above the disk and-recessed to afiord a passage during filling but crushed into said undercut in the neck, in closed condition, to force and hold said disk to its seat, substantially as described.
