THOMAS LUCIEN TALIA FERRO, OF WHEELING, VIRGINIA. .ASSIGNOR, BY LIESNE ASSIGNMENTS, 'I'O PHOENIX-HERMETIC COMPANY. OF NEW YORK, N. -Y., A. CORPO- RATIO'N OF NEW YORK.
To all whom it may concern: x
residing at Wheeling. in the county of Ohio, State of Test Virginia, have invented certain new and useful Improvements in Sheet- Metal Covers for Receptacles, of which the following is a description. re'lere'nce being had to the accompanying drawing, and to the figures of reference marked thereon.
The invention relates to new and useful improvements in closures for receptacles and more particularly to a sheet metal closure for a receptacle of glass, porcelain or the like.
An object of the invention is to provide a cover or'clo'suie fofa receptacle of the above character,which is so shaped that the same may be attached to the receptacle and firmly retained thereon by pressure applied to the outer extreme edge of the cover or closure, and which cover orclosure is also so shaped that when attached to the receptacle an annular sealing shoulder will be caused to embed or press against the sealing n'iatcrial flexed inwardly by atmospheric pressure,
when said receptacle under vacu um.
These and other oluects Will in part be obvious and will in part be hereinafter morefully disclosed.
In the drawings,l*igure l is a sectional view showing my improved cover applied to a receptacle before said cover is bent to close the same: Fig. 2 is a similar view showing the cover bent into closing contact with the Walls of the receptacle: Fig. I) is an enlarged detail in section showing the cover when first applied to the receptacle and before the outer wall of the channel is bent into con{ tact therewith; Fig. 4; is a view similar to Fig. 3, showing the outer wall of the U- shaped channel bent into closing position; Fig. 5 is a-view similar to Fig. 4. showing a receptacle having a shoulder at its upper end and my improved cover applieththereto.
In carrying out the invention I have provided a sheet metal cover which comprises a circular portion having its periphery bent Specification of Letters Patent.

to form a U-shaped annular channel, which is adapted to engage the upper edge of the receptacle to be closed. This channel is lined with asealing material. The outer wall of the channel is formed with a substantially vertical portion at the upper part thereof, and the. lower edge of this waltis curved outwardly so as to Form with thevertical wall an annular sealing and gripping shoulder. which is adaptedto press the sealing material when the lower edge of the out r wall is bent inwardly toward the wall of the receptacle.
formed of glass or porcelain or the like, and
receptacles of this character are often slightly irregular in contour and the surface of the glass or porcelain may also contain uneven sections. .These irregularities or imperfections in the mouth of the receptacle to llt closed make the use of a cover having its outer wall vertical throughout impractiperlcctions in the side walls or edges of the month of the receptacle to be closed.
Referring more in detail to the drawings, 1 have shown a receptacle 1, which is circular in cross section and the side walls of the receptacle at the upper edge thereof are substantially vertical. The receptacle is preferably made of glass, porcelain or the lil c. as above noted. and is adapted to be closed by my improved cover. This cover is made of metal and consists of a c-irculauportion '2. This circular portion has its periphery bent to form a U shaped channel 3, which is adapted to engage the upper edge of the side walls of the receptacle l. The inner wall 4 of the U-shaped channel is substantially vertical.- The upper portion 5 of the outer wall of said U-shaped channel is also substantially vertical, and the lower edge of this outer wall is curved outwardly as at 6, forming with said vertical wall an annular shoulder 7, which may be said to be 'a sealingshoulder. The inner wall of this' .U-shaped channel throughout its entire extent is provided with a sealing material 8, which'is preferably a plastic sealing mate-' The inner. wall'of said U-shaped channel is joined to rial of any suitable character.
- nel permits the cover to be readily placed on.
receptacles which may be slightly irregular in contour or formed with slight imperfections in the surface of the glass or porcelain. Then again, the bending of the metal outwardly at the lower end of the outer wall of the U shaped channel tends to strengthen the metal and I have, therefore, in eifect, a strengthened annular shoulder 7 which becomes embedded in the sealing material and also serves to grip the vertical wall of the receptacle and retain the cover on the re ceptacle.
"1 In Fig. l of the drawings l have shown the' cover applied to the receptacle and said cover held seated thereon by a chuck 9. The crowding of the cqgverv on to the receptacle by the chuck 9. tends to open the. channel or bend outwardly the outer wall. A closing tool 10, indicated diagrammatically in this figure, is formed with a cam shoulder 11,,
which is so positioned that after the cover is firmly seated by the chuck, a downward movement of the toolwill cause said shoulder to engage the outer wall of the channel and as this cam shoulder moves down the outer wall, the sealing shoulder will be bent inwardly toward the wall of the receptacle. The greatest pressure of, the closing toolis applied to the outer extreme edge of the curved portion ofthe outer wall, and the forcing of this outer edge in toward the receptacle causes the shoulder 7 to become embedded in the sealing material, and said shoulder serves, in a measure, as a fulcrum, causing the upper portion of the outer wall to bulge orcurve outwardly, as clearly shown in Figs. 2 and 5. 4 This curving of the outer wall causes the sealing shoulder to move upward slightly in the sealing mate rial, and crowds the sealing material upwardly, thus filling the part of the U-shaped channel directly above the sealing shoulder. This embedding of the sealing shoulder in the sealing material and the upward crowd ing of the same will cause the cri-zzles, edgeblisters, pressovers and other imperfections in the glass or porcelain to be filled and thus effectively seal the receptacle.
The outward bending of the outer wall of sealing material.
the channel'as the sealing shoulder is pressed inwardly toward, the wall of the receptacle positions the metal so as to more ellectively retain the sealing shoulder embedded in the sealing material and in close contact with the vertical wall-of the receptacle; This holding of thesealing shoulder in close gripping porcelain receptacle is very eflicient in holding the cover on the receptacle, regardless of Whether there is any sealing" material used in connection with the cover. It will contact-with the side wall of the glass or be understood, therefore, that this stiffened annular shoulder may be used in connection with the closing of a metal cover on a glass or porcelain receptacle without the use of a My improved cover is especially adapted for the closing of a receptacle which is to be put under a vacuum. While the cover is resting loosely on the receptacle, as in Fig. 1- of .the "drawing, and perhaps beforethe chuck has engaged the cover .to-crowd the same onto'the receptacle, said receptacle is placed under a vacuum and while in the vacuumizi'ng chamber the cover is preferably bent into closing position,*as indicated in Figs. 2 and 5.
At the center of the circular portion 2, I i i have provided a restricted dished section 12, which normally projects outwardly from the plane of the cover. When, however, the
cover is placed under'vacuu'm, said dished section is so shaped that it will be flexed ,inwardly to the position shownin Fig. .2, 'and said'dished section will remain'in this position aslong as the rece tacle is under proper vacuum. ThlS dishe' section, therefore, provides an eflicient and readily accessible means for determining whether the receptacle is underproper vacuum.
11 Fig; 5 of the draw ng I have shown my improved cover as applied to a' receptacle 13, wherein the upper edge 14 is thickened so as to form a ledge 15 in the outer wall of the receptacle. Thisledge is preferably so disposed relative to the sealing shoulder 7 of the cover that when the lower edge of the outer wall of the U-shaped channel is bent inwardly said sealing shoulder will lock underneath the projectlng shoulder 15 on the receptacle, 1:
It is obvious that f ninor changes in the details of constructionj-and the arrangement of parts may-be made without departing from the spirit of the invention, as set'forth in the appended claims.
Having thus described my invention, what I claim is:
- 1. A receptacle having a vertical wall at its outer upper edge and a sheet metal cover therefor comprising a circular portion having the periphery thereof bent to form a downwardly projecting wall, the lower portion of said wall of the cover being normally bent outwardly relative to the upper portion of said wall and forming with said upper portion an inwardly projecting shoulder when said cover is secured to the receptacle, which shoulder is adapted to grip said vertical wall of the receptacle and hold said cover thereon, the vertical wall above said gripping shoulder being bulged outwardly when said cover is closed on the receptacle whereby said gripping shoulder is held in contact with the receptacle.
2. 'A receptacle having a vertical wall at its outer upper edge and a sheet metal cover therefor comprising a circular portion having its periphery bent to form a downwardly projecting wall, the inner surface I of said wall of the cover having a lining of plastic sealing material thereon, the lower portion of said wall of thecover being normally bent outwardly relative to the upper portion thereof and forming with said up-- per portion an inwardly projecting shoulder when said cover is secured to the receptacle, which shoulder'is adapted to-be embedded in the sealing material thus forming a conof the receptacle andhold the cover thereon.
3. A receptacle having a vertical wall at its upper edge and a sheet metal cover therefor, comprising a circular portion having its periphery bent to form a U-shaped channel engaging said Verticalwall of the receptacle, said channel having a lining of sealing material on the inner surface thereof, the lower portion of the outer wall of said channel being bent outwardly relative to the upper portion of said outer Wall and forming with said upper portion an in wardly projecting-shoulder which is embedded in the sealing material and forms a continuous sealing line therein, and which grips said vertical wall of the receptacle and holds the cover thereon.
In testimony. whereof, I afiix my signature,
in the presence of two witnesses.
