UNITED STATES PATENT OFFICE.
FRANCIS IP. MOCOLI., OF' ST. ANDREWS, NIiw BRUNSWICK, CANAI A, ASsIGNoR To AMERICAN KEY CAN COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION or NEW JERSEY.
.f1 minion of Canada, have invented a certain new and useful Improvement in Roll-Caps, and declare the following to be a full, clear, and exact description of the saine, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
^ My invention has for its object to produce a. closure for openings in cans or other re-' ceptacles which may be rolled up on a key so as to uncover the openings regardless of the size of the openings or their size relative to the can head or other` part in which they are located. i
The various features of novelty whereby my invention is characterized will hereinafter be pointed out with vparticularity in the claims; but for a full understanding of my invention and of its object and advantages, reference may be 'had to the vfollowing detailed description taken in connection with the accompanying drawing, wherein:
Figure 1 is a plan View of a can having a closure arranged in accordance with a preferred form of my invention; Fig. 2 is a central section taken on line 2 2 of Fig. 1; Fig. 3 is a section taken on line 3 3 of Fig. l; and Fig. 4 is a section through the tongue on line 4,-4 of Fig. "1.
For the sake of brevity I have illustrated my invention as applied only to a can having an openlng therein smaller than the diameter of the can body; but I do vnot .desire to be limited to this particular field since my invention is applicable to the closing of openings of Yvarious different kindsand in various different receptacles'. Furthermore my invention is not .limitdin its application to receptacles for it is adapted to closeopenings in partitions or walls used for anyV Referring tothe form of my invention and the use illustrated in the drawing, A represents a can having in the head ,thereof an opening B. The can head is depressed about the opening so as to form an annular V- shaped groove C adjacent to and surrounding the opening. v i L D is a cap of a size and Shape to close the Specication of Letters Patent. Application filed August 25, 1910. Serial No. 578,874.

opening and fill the area bounded by the groove. In accordance with my invention I form on thel cap a depending annular flange E which fiares outwardly as it recedes from the cap and fits closely over the inner Awall of the groove. The free edge of the flange is turned up and out, as at F, so as to form a narrow annular fin which rests upon the outer wall of the groove near the bottom of the groove.
The cap may be soldered in place in any suitable way, this being conveniently accomplished by passing it throiigh any usual form of soldering machine. By providing the cap with a tongue projecting therefrom at a point adjacent to the iin, the tongue may be inserted in the key and Wound thereon until the soldered joint is reached. The
thereof adjacent to the tongue and, after the joint has once started to tear, no difiiculty lis experienced in progressivelyrolling up the cap and tearing the entire joint as the rolling proceeds. The portions of .the fin immediately adjacent to the tongue facilitate the starting of the tear, while the remainder, of the lin always brings a portion of the soldered joint'intoa plane which is weakest under the ystrains imposed by the rolling` process. Therefore the fin will provide new starting points all along the joint so that, as Ythe rolling progresses, the joint will be continually attacked at points offering the least resistance.
In the preferred arrangement the tongue is a continuation of the flange on the cap and projects from the free edge thereof as indicated at G. Furthermore I prefer to carry the fin partially along the sides of the tongue -as indicated at f so that the base of the tongue will be stiffened anda good grip will be obtained upon the fin before the actual process of severing the main joint is begun. The tongue is of course bent upwardly so as to carry its free end above the groove and it may then be bent laterally :so as to lie against the head of the can.
While I have illustrated and described with particularity only a single preferred form of my invention Il do not desire to be limited to the specific details so illustrated and described; but intend covering all constructions and arrangements which fall within the terms employed in the definitions of my invention constituting the appended claims.
lVhat I claimis: 1. A roll capcomprising a disk having an annular dependin flange, said flange flaring outwardly as-it recedes from the disk, a
tongue projecting from the flange, andthe the tongue adjacent to the flange being bent upwardly so as `to form "aslight narrow lin encircling the flange and extending at least partially along the sides of the tongue.
3. A irll cap lcomprising a disk having a depending annular flange, said flange fiar'- ing futwardly as it recedes from the disk,
y a narrow tongue projecting from the free l edge of the flange. and theedge of the flange and tl`e adjacent portions nf the sides of the tongue being bent upwardly so as to form .a
narrow lin encircling the ange and extendf K ug at least partially alf ng the sides of the l. ln 'ctn'ibinatiom a member having an opening therein, there being 1n saidmefber a groove or 'depression surrounding said opening. a cap adapted to close said opening, said cap aving a Harige shaped to extend into said groove or depresslon, the free 'edge of said flange being bentoutwardly so as to form a slight narrow fin, and-a tongue projecting from said flange at a pointadjacent to said fin.
5. In combination, a member having, an
opening therein, said member having agroove V-shaped in cross'section surroundlng said-l opening and 1n proX1m1ty to said opening, a cap adapted to close said opening, saidv cap havin a depending flange shaped to fit over t e inner wall of said groove, the free edge of the flange being turned upwardly so as to form a slight narrow fin engaging with a portion of the outer wall of said groove, and a tongue projecting from said flange at a point ady jacent to said fin. j
6. In combination, a member having an opening therein, said member having a groove V-shaped in cross section surrounding said opening andA in proximity to said opening, ,a cap adapted to close said open- .ing, said'cap having a depending flange shaped to fit overthe inner wall of said groove, the free edge of the flange being turned upwardly so as to form a slight nai row fin engaging with a portionof the outer wall of said groove, and a tongue projecting from said flange at a point adjacent to said fin, said tongue being bent upwardly so as to extend above the top of the groove.
7. In combination, a member having an opening therein, said member having a groove V-shaped 1n cross section exten mg arrund saidopenlng. a cap arranged to close said opening and extend into proximity tol said groove, said cap 'having .a depending flange shaped -to fit over` the inner wall of said groove, a ton ue projecting from the free edge of said ange and extendingmpwardly out of the groove, the free edge of the flange being bent upwardly so as to form a narrow enga 'ng withthe outer wall of said groove, said fin Yextending at least 'partially along the sides of the tongue. n In testimony whereof, I sign this specification inthe presence of two witnesses.
