IMPROVEMENT IN METAL CANS, CASES, BOXES, 810., ,FOR- PRESERVING FOOD, GUNPOWDER, LIQUIDS,

euros, Ol-LS, AND'OTHER ARTICLES.

Specification forming part of Letters Patent No. 43.37% dated-June 28, 1864.

I0 all whom, it may concern:

. Be it known that I,'JEAN BQUVET, of La Rochelle, in'the Empire of France, have-i11 wented a --new and useful Improvement in Metal Cans, Cases, Boxes, &c., Designed for- Preserving Food, Gunpowder, Liquids, Paints, 1

Oils,-and otherArticles; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and-to the letters of reference marked thereon,

The nature of my invention consists of arr improved mode of closing or sealing tinfpreserve-boxes and other vessels in a manner which allows their being opened without the use of sharpinstrnments, and consequently without risk of injuring the contents, and at the same time without injuring the box or lid, so asto allow theirbeing used again.

In order to make others skilled in the art understand the manufacture and use of my invention, Iwill now proceed to describe the same more closely, referring thereby to the annexed drawings, in which like letters denote like parts in all the'figures. 1

Figure I shows a longitudinal sectional View over the line X X of Fig. II of a-tin preserve-box of a round shape. Fig..II is aplan or top view taken from theinside-ofthe box. Fig. III is a similarview taken from the outside. Fig. IV represents an outside top view -of a square tin box of a shape generally made use of for preserving sardines.

A represents the body of aftin preservebox or sardine'box made in any known manner, the upper end 'or rim of which is bent toward the inside, so as to make this rim form a sort'of inverted gutter or hollow swelling a.

1?, represents the lid, the edges of which are also bent toward the. inside, so as to form a similar gutter or swelling, b. v

" 0 represents a wire made of tinned iron or other suitable metal in. any desirable shape,

but of a size to fit into the vacant space left between the gutters a and b. The body of the box is'put. over a form or- -block of wood or metal, (corresponding with its size and shape,) and receives thereupon the top or lid Bby the latter being laid onthe form or block. The lid is then surrounded by 'said wire O, and the two gutters a andb, thus connected by the wire 0, are then soldered together, the soldering being done on the outside of -the lid over the wire. The wire should not only reach around the lid, but one end, e,..of it should also protrude a little to the outside of the same .and be free from solder. When the box is to be opened,this small free ends of the wire is taken hold of by'a pair of pinchers or a similar contrivance, and

with .a little efiortjs turned or coiled around the pinchers. It thereupon gets loose from the' solder, and by becoming free itself separates the lid from the body of "the box without injury to eitheror the c tents. This new mode of fastening and soldering the lid to the body of t ebox is fully as secure as the old ones:

Boxes thus secured can besubmitted to the same amount of boiling heat, and handling as others, and have the advantage of much greater convenience in opening them.

While the box is in process of being made,

ciple embodied in thi's invention is applicable not only'to tin cans and boxes designed for-the reservation of food and liquids, but also to eta-llic vessels containing gunpowder, oils. pai ts,1chemicals, books, or the many other articles for which (while in transit or store) metal cases,;ican s, boxes, or other metallic vessels are generally used for the purpose of preservation and protection against the elements.

Having thus given a full description thereof, I .claim as my invention and desire to se .cureby'LettersPatent of the United States- The manufacture and use of metal boxes; cans, cases, and other metallic vessels her.- metically sealed or closed by inserting and soldering a wire between the body and the in tended opening of such metal box, can, ease, and "other metallic vessel, one end oflsuch wire protruding at the outside for beginning and effecting such opening;
