Specification of Letters Patent. Patented J 11"], 1915a Application filed February 5 1916. Serial No. 76,342.
To all whom it may concern:
Be it known that I, CHARLES W. GRAHAM, a citizen of the United Grestwood, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Cans, of which the followingis a specification.
The invention relates to a hermetic can seal, produced without the use of solder, and preferably by the aid of an interposed liner or gasket, of paper or equivalent material, the flanges of the can cover and body being held together to form such hermetic seam by a U-shaped sealing strip which embraces said flanges between its upper and lower this sealing strip being either wound around the can and the flanges thereof and being by such winding operation conannular form, or being preliminarily formed of annular shape and then sprung overthe' said flanges and clamped down thereupon with suflicient pressure to form the hermetic seal. Or the said sealing strip may be of other suitable formation to accomplish the tight clamping together of the cover and body flanges, and so as to be removable for the unsealing of the can. The said sealing strip is of metal of such malleable character as to permit of the said operation and as to preserve the set which is imparted to it in the sealing operation, and also as to permit the strip to be unwound from the flanges without difliculty, when the can is to be opened.
The covers of cans of this character are or may be formed with a vertical wall or shoulder which is seated within the mouth of the can body in contact with the walls thereof, to permit the cover and the flanges to be firmly grasped and pressed by the sealing instrumentalities. \Vhen suchcans are processed there is often a severe internal pressure exerted on the cover which tends to press it outward and draw it away from the walls of the body, and which also tends to displace the COVGl' flange from its proper sealed position within the sealing strip; and the present invention has for one of its objects to hold the flange of the cover properly in place notwithstanding such internal pressure.
States, residing at To this end a portion of the cover is caused to abut against a portion of the body flange at the outer edge of the latter, so that any tendency of the cover flange to be drawn or to move inwardly is directly opposed by the body flange; also the formation of the cover flange which enables it to have such abutting function incloses and protects the ring liner or gasket and aids in maintaining the latter in its proper position on the cover flange while the cover is transported or handled prior to the seal-ing of the can, and may in fact be clamped flat on the gasket.
It is to be understood that abutting is used in. the sense of opposing, for in commercial manufacture there will or may be a slight crack or space between the opposing edges of the cover and body flanges, which is however taken up by the least indrawing of the cover flange, and the contact thus established between the flangeedges holds the cover flange from any displacement from its proper location in the seam.
Another object of the invention lies in its adaptability to forming a tight and simple seam for unprocessed goods.
When used:
for such goods the abutting feature need not i be so strictly adhered to, and more clearance may be left between the juxtaposed flangeedges, which will somewhat facilitate manufacture and to all appearance produce the same seam.
With such objects in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed. with the :understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature of the invention.
In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustration. In the said drawings:-
Figure 1 is a sectional view at one end and corner of the can body and cover, showing portions of the same, the parts being separated.
' same time compress the lip portion 4, a vertical wall 5, and
Fig. 2 is a similar View, with the cover applied to the body, showin alsothe seal- 111g strip about to be appliec to inclose the cover and body flanges.
Iig. 3 is a similar view with. the parts .clamped together'in sealing position.
; I ig. 4 1s a view similar to Fig. 3, but embodying a modiflcatlon in which the inner edge of the upper memberof the sealing t iereon.
Fig. 5 is aplan view of the sealed can,
Fig. 3.
Referring to the drawings, 1 indicates the can body formed at its mouth with an outstanding peripheral flange 2. 3 is the end or cover formed with a depressed central ing flange 6 corresponding with the body ange 2 and formed with bent peripheral rim, ledge or lip 7 at the outer margin of the flange 6, which lip eX- tends downward and thence inward, sufficiently to inclose the gasket or packing ring 8 on its under side, and also to form a shoulder or abutment which engages the outer edge of the body flange, whereby the cover is assembled with the cover. 45
flange is held from horizontal inward movement relative to the body flange.
The packing is indicated as a paper ring liner, but it may be of other material and object of producing a hermetic seal, and allows of the described abutting of the cover flange against the body may curl around and lie at the under side of the packing, so as to secure it in place Without clamping it tightly, or it may be pressed down on the packing when the latter In the former case, when the sealing strip, hereinaftermentioned, is applied the pressure ofthe lower member of the strip will compress the body flange against the packing and at the against the packing, so that the lip is brought into horizontal line with the edge of the body flange to effect the said abutting engagement.
9 indicates the sealing strip formed of substantially U-shape so as to have upper and lower flanges or clamping members 10 and 11. This sealing strip is preferably applied of sufficient length so that its ends will overlap somewhat, as shown at 12 in Fi 5.
Ihe inner edge of the member 10 may be extended inward, as shown at 13 in Fig. 4:,

The lip 7 so as to lap slightly over or within the cover the parts being in the position indicated in th standing flanges, and a sealing strip encircling said flanges, and binding them together into a hermetic joint, the outstanding cover flange having a curled and flattened edge that embraces and binds the edge of the gasket and also forms an abutment with e edge of thel'body flange.
In a can, in combination: a body having an outstanding peripheral flange; a can end having a flange cooperating with the body flange to form a seam, and a lip which extends downwardly and inward toward and against the edge of the body flange; a sealing strip having opposing members between and end flanges may be clamped; and a gasket interposedbetween said flanges and lying within and above the lip of the end flange.
In a can, in combination; a body having at its month an outstanding peripheral flange; a can cover having a flange cotiperating with the body flange to form a seam; a sealing strip having opposing members between which said body and cover flanges may be clamped; the peripheral edge of the cover flange and the peripheral edge of the body flange having an abutted engagement which .holds the cover flange against being drawn inward out of its sealing position; and a packing interposed between the said flanges out of line of said engagement, and. extending over said line.
4. In a can, the combination of a can body having an outstanding seam flange; a shouldered can cover having a wider outstanding seam flange; and a gasket interposed between said outstanding seam flanges; said can body flange, said cover flange and said gasket lying in parallel planes and in frictional contact; a sealing strip encircling said seam flanges and said gasket, and bind ing them into, a tight joint; the outstanding cov'er flange having a peripheral folded over edge that embraces and securely binds the edge of the said gasket and at the sametime forms an annular space in which the said flange lies in close proximity to the said folded over edge to form an abutment when the cover is under gaseous or atmospheric pressure.
