IMPROVEMENT IN CANS.

Specification forming part of Letters Patent No. 177,902, dated May 23, 1876; application filed September 3, 1875.

To an whom it may concern:

Be it known that I, ARTHUR R. WALLER,

- of the city, county and State of New York,

tear of the cans.

The nature of my improvement will be readily understood by reference to the accompanying drawings, in which Figure 1 represents a plan view of a portion of a tin cut ready to be employed in manufacturing parts of cans according to my invention. Fig. 2 represents the periphery or sides of one of my improved cans laid out flat; and Fig. 3, a section of the same. Fig. 4 shows a perspective view of one of my improved cans complete.

Similar letters of reference are employed to indicate corresponding parts wherever they occur.

According to my invention 1 take a sheet of soft tin or other suitable metal, which I cut into strips a, as shown by Fig. l. I then take one of the said strips a and swage or solder the same on the side ofa sheet, b, ofthe proper size to form, when joined with a strip, a, the

side or periphery Bot a can, A, as shown by Fig.2. The combined sheet, Figs. 2 and 3, having been thus formed, I then attach the top 0 and bottom D in the ordinary manner,

leaving the opening E to be closed subsequently.

It will be seen readily that by forming the sides or periphery B of a can with a strip of soft metal, a, applied, as shown, in such manner that the said strip a shall. form a continuous portion of the width of the sideor periphcry, and having, when the can is fully completed (as shown by Fig. 4) a ring, E, of soft metal around the can A, that great economy is efi'ected in the manufacture of cans of this description, and, in addition, by inserting the point of a knife in the ring E and running it round the can, the end of the said can can' be very readily opened.

1 am aware that annular portions of soft metal have been inserted in the ends of cans for the purpose of facilitating the opening of such cans, but in this case great waste is effected in the manufacture. As represented by the dotted lines in Fig. 1, it will be seen that out of the same sized sheet of metal, according to my invention, I can obtain the necessary material for the soft portion of eight cans. According to the process of manufacture wherein circular disks of metal are inserted into the ends of the cans only three such disks can be obtained.

1 am also aware that metal cans have been constructed with a strip of soft metal soldered to the Wall of the can and afterward to the cover of the same, there being a thickness of harder metal inside the soft metal.

Having thus described my invention, I would have it understood that I lay no claim to a ring or plate of soft metal inserted in the top or end of a metal can, as I am aware the same has been previously used; but

What I do claim, and desire to secure by Letters Patent, is-

As a new article of manufacture, a metal can constructed with a strip or rim of soft metal, E, inserted between the ends or top and bottom of the can, and solely forming a continuous portion of the periphery or sides B thereof, substantially as shown and described.
