BOTTLE-SEALING DEVICE.

SPECIFICATION forming part of Letters Patent No. 582,762, dated May 18, 1897.

Application filed December 8, 1892.

To all whom it may concern.-

Be it known that 1, WILLIAM PAINTER, of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bottle-Sealing Devices; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of my invention.

My said improvements relate to hard-metal flanged sealing-caps adapted to he used in connection with sealing-disks and with hot tles provided with an annular locking-shoulder; and my invent-ion consists in providing the cap-flange at its edge with an integral bead formed by turning the metal upon itself in such a manner that when the cap is placed with its sealing-disk on a bottle and the diskproperly compressed the beaded portion of the flange of the cap may be bent inwardly against the bottle-head beneath the locking-shoulder and effect a firm and reliable lockiug union of the flange with the bottle-head. The metal composing the bead incloses more or less interior space, and the outer portion of the metal can therefore be bent inwardly to a considerable degree by pressure applied thereto, and at the same time the same pressure will cause the metal comprising the interior of the bead and the flange above the head to be forced inwardly and bent into firm locking contact with the glass without endangering the latter, which would be liable to fracture, and especially at the locking-shoulder, should the metal be directly forced into contact therewith. In other words, the bead on the flange enables the cap to be firmly locked on a bottle-head by the application of a yielding or cushioned pressure, as between any necessarily hard-surfaced compressing device and the surface of the glass. A similar result is accomplished with the corrugated flanged caps heretofore devised and patented by me; but my novel beaded flanged caps are well adapted for certain kinds of bottling, and they can be as cheaply produced as the corrugated caps and by means of simpler and less expensive tools.

Serial No. 454,467. (No model.)

To more particularly describe my invention, I will refer to the accompanying drawings, in which- Figures 1, 2, and 3 illustrate, respectively, in side, top, and sectional views, one of my novel sealing-caps in what I deem its best form, the bead being one in which the metal has been turned outwardly. Fig. 4 illustrates in section a bottle-head with one of my novel caps with its sealing disk initially placed therein. Fig. 5 in like manner illustrates the disk under pressure and the cap locked to the bottle. Fig. 6 illustrates in section one of my sealing-caps in a modified form, its bead being one in which the metal is turned inwardly. A

The cap A of Figs. 1 to 5, inclusive, has a rounded top a and a flange b, which flares slightly outwardly, but however much these may be varied in their form and character the edge of the flange has, essentially, a welldefined bead c. This bead may, however, be varied as to the form of its cross-section, although the best results Will accrue when it is substantially circular, as shown, andit should have sufficient interior space to admit of the .metal at the outer side to be forced inwardly to a more or less extent without engaging in close contact with the coincident metal at the interior side of the bead, the object and intent thereof being to secure the inward bending of the metal at. the inner side of the bead against the coincident surface of glass during the sealing operation by means of pressure applied to the outside of the bead. This exterior pressure is transferred from one point to the other by way of the metal which comprises the rounded edge or bottom of the bead. Thisbead is formed by turning the metal outwardly and upwardly or toward the top, and more orless upon itself, as shown. The sealing-disk cl is preferablycom posed of thinly-sliced cork, but other suitable materials may be employed.

Referringnow to the bottle-head B, it is to be understood that it has a rounded lip e and an annular locking-shoulder 6' below the lip, as is usual with bottles heretofore used with my aforesaid corrugated metal caps, and it will be seen that the rounded top of the cap A internally conforms to the externallyrounded surface of the bottle at its lip, so

that the sealing-disk (Z may be forced into 5 extensive packing contact upon and adjacent to the lip of the bottle, as shown in Figs. 4 and 5.

The general contour and dimension of the interior of the cap should be such as will enable the appropriate portion of a bottle-head to be quite freely received therein, as shown in Fig. 4, so that when pressure is applied to the top of the cap for properly compressing the sealing-disk the bead 0 will be so located with reference to the locking-shoulder c that a proper engagement therewith may be secured.

When the bead is well closed at its top, as shown, the setting-pressure may be applied either radially or concentrically and in the plane of the recess just below the shoulder, or by a vertical movement, as by the use of such a hollow internally-tapered bendingtool as is employed by me in setting corrugated caps and disclosed in my Letters Patent No. 73,776, dated April 26, 1892. however, absolutely essential that said bead should be closed at its top, but when the caps have beads which are open at the outer side they should be subjected to pressure in radial lines only. However this pressure may be applied for setting the cap the bead will be distorted more or less regularly at various points, according to the varied contact of the metal at the inner side of the head with the glass, and also according to the extent to which the peripheral dimensions of the bead may have been reduced. It is not necessary with these caps to always compress the entire bead, it being quite practicable to obtain good locking contact if pressure be evenly applied to the bead at five or six different but equidistant points.

The cap A of Fig. 6 dill'ers from cap A only in that the bead c is formed by turning the metal inwardly and toward the top of the cap, thus leaving no external opening, as when the metal is turned outwardly, as in the head 0 of cap A. \Vith this internally-turncd form of bead, whether the edge be well closed in toward the sides of the flange or an opening left, the cap may be equally well set or fixed upon a bottle-head, whether the pressure be applied radially or by a complex longitudinal It is not,

and radial action, as by a hollow tapering bei'iding-tool.

"While the heads 0 or c are integral with flange, it is not always essential that they should be solid peripherally, because for many kinds of service the beads may be open at short intervals at right angles to the rounded edge of the flange. These beaded caps may be relied upon for performing good service even when composed of specially thin light metal, the best form of which is tinplated sheet-iron and of the class known as roofers tin.

When the caps in either of the forms shown have been properly set, much force must be exerted for their removal in opening a sealed bottle, and hence it is desirable to use a lever-shaped hook, although an ice-pick or other pointed tool may be readily inserted between compressed bead and the glass at one or more points, the lower rounded edge of the flange being favorable to such insertion.

Although not perhapsmaterial to this specification I will state that these caps in either of the forms shown are developed from disks or blanks of sheet metal which are struck up in dies, the beads being developed by the use of annularcup-shaped diesections, which are appropriately formed in each case for producing the particular kind of bead desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. Allard-metal sealing-cap havinga flange provided at its edge with an integral bead, having an open interior and adapted to be bent into engaging contact. with a bottle-head substantially as described.

2. The combination substantially as hereinbefore described, of a bottle having 011 its head an annular locking-shoulder, a sealingdisk, and a hard-metal sealing-cap provided with a flange having a bead at its edge, the said disk being under sealing-pressure on the lip of the bottle, and said head bent into locking contact with the bottle-head adjacent to the locking-shoulder, and confining the disk in sealing contact with the coincident surface of the bottle.

WILLIAM PAINTER.
