, FRANCIS A. WALSH, OF CHICAGO, ILLINOIS.
SH EET-M ETAL CANQ.
SPECIFIQATION forming part.of Letters Patent No. 252,342, dated January 17, 188.2.
Application filed June 23, 1881.
10 reference being had to the accompanying drawin gs, forming part hereof, and in which Figure 1 represents a sectional side elevation of my improved can, and Fig. 2 represents a modification of the'same. Fig. 3 represents a I 5 canin which the cover is cut away and raised on its hinge; and'Fig. 4 represents a plan of the same, showing the extent of the out and channel 9.
Like letters of reference indicate like parts. Theobjeot of my invention is to provide a can which shall be provided with a hinged or slip cover at pleasure, be cheaper to construct, require less stock, and yet answer all the purposes of the can for which Letters Patent, dated March 16, 1880, No. 225,499, were issued to me, and to that end I construct my can'as follows, to wit: I
In the drawings, 11 represents the body of thecan,provided with an annular ring, '17, which the cover b may be on a'level, or atleast not extend beyond the top of the body of the can, so as to protect the thin top in handling and shipping. On the inner circumference of the ring a is formed acollar, c, and the ring between the collar and body of the can is formed into a shape approximately as shown by the surfaces cl 0. The cover b is formed with a rim, 0, to fit closely over the collar 0, and with it. is formcdthe flange cl, the outer part of which is bent upward parallel to the side 6 of the rim, and the top part, f, is again made flat, so as to fit upon the top of the ring 1'.
The cover b may be soldered on the ring 1', at e orf, and the ring 11 soldered on the body of the can;.or'the ring, body, and cover may 'be'nnited together by double seaming.
Care is taken when forming the ring 21 and cover b that a channel, g, may be left between :0 the ring and cover, which is done by making the rim 0 shorter than the collar 0, so that the r flange at will form a bridge across the channel is countersunk into the body of the can, so that (No model.)
g, as shown in Fig. 1, and thereby also form the annular chamber g, as shown in Fig. 2. An annular ring of paper, wood, or anything which will 'not unite with solder, may be laid upon the shoulder 01, Fig. 2, so as to form the chamber g. This, in soldering, prevents the parts from being united under the flange d, so that the point of a knife may be passed through upon the ring t or collar 0, and form a convenient support for it in opening the can.
The collared ring is preferably made of any ordinary sheet metal; but the cover b should be made of thin material, preferably thin taggers 6 iron or tin,thatwil-l readilyyield to an ordinary pocket-knife.
Theoannular space or channelg is not absolutely necessary; but for the purpose stated is found more convenient. 0
When the can is opened as described a re movable slip-cover is provided.
In Fig. 2 the top of the can is crimped or bent inward, so as to form a shoulder, d,.upon which is formed a collar, 0, and the cover I) is formed with a rim, 0, fitting over the collar 0, a flange, d, fitting over the shoulder tlf, and an extcriorlap, 6 which is soldered to the can. In this case the knife is passed horizontally into the chamber 9, and when the cover I) is cut away a flange is left upon the cover.
In Figs. 3 and 4 the ring i is provided with a flat part, h, which is formed by sinking the channel 9 below that part, as is shown by the dottedlincs in Fig. 4, which represent the sides 85 of-the channel, and which terminate on each side of h. The full line between the dotted lines'represents the cut of the knife, thus leaving the partof the cover b at h uncut, and thereby forming a hinge of that part of the flange.
Cans so constructed are securely closed by means of the cover I), from which, when the slip-cover is cut away, the contents of the can may be used from time to time, and securely closed during the interval. The soft-metal diaphragm is dispensed with, thus effecting a saving of considerable material as well as labor, while the end desired is equally well attained.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-
1. A can provided with an opening and collar, a, over which is fitted a cover, 11, having a rim, 6, and flange d, of thin and soft metal, overlying an annular channel g, said flange being soldered beyond said channel and cut to open the can bypassing a knife through the 5 flange into the channel, substantially as and for the purpose specified.
- 2. A can, a, provided with a collar, 0, and flanged slip-covert, adapted to be cut away with a knife and united beyond the flange d 10 to the annular ring supporting said collar, and so formed as to leave an annular chamber, 9, substantially as and for the purpose specified.
3. The channeled rim 1', provided with flat part hand collar 0, and provided with a flanged 15 slip-cover united to the top of the can and FRANCIS A. WALSH.
