UNITED STATES PATENT FFIGE.

SAMUEL B. BUSHFIELD, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE- HALF HIS RIGHT TO ROBERT D. MORRISON AND JOHN H. WARNER, OF

SAME PLACE.

IMPROVEMENT IN SHEET-METAL BOXES.

Specification forming part of Letters Patent No. 153,932, dated August 11, 1874; application filed December 29, 1873.

To all whom it may concern:

Be it known that I, SAMUEL B. BUSIIFIELD, of the city and county of Baltimore, and State of Maryland, hay e invented a new and useful Improvement in Boxes; and I do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings making part of this specification, in which Figure 1 is an end view of the box embodying my invention. Fig. 2 is a top or plan view thereof. Fig. 3 is a view of the inner side of one end thereof. Fig. 4 is a face view of the blank.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in constructing the body of a box of a single piece of metal in such a manner that there are no open joints, the outside of the box is uniform, and solderingis not required.

Referring to the drawings, Arepresents the box, which is constructed out of the piece or blank B. 0 represents folds, which are made at the cornersof the blank by means of the lines a 1), extending inwardly from the edges of two adjacent sides of the blank, and the lines 0, extending from the corners of the blank to the points of junction of the lines a b. The sides D of the blank will be turned up at the lines d; and the sides or ends G at the lines f. The diagonal line c-of each fold O turns inwardly, and causes the formation, at each corner of the box, of a double-fold thickness or piece, H, diagonal or triangular in shape, which fold is then laid against the in nor face of one side or end of the box, and, thus uniting the corners of the box, the latter is complete.

It will be seen that there are no open joints or seams in the box, and escape of its contents cannot occur. The pieces H also serve to strengthen or stiffen the box, and said pieces so slightly reduce the area or capacity of the box that the reduction is immaterial. The outside of the box is uniform at all points. there being no projecting parts or exposed cut edges of the material at the sides.

Another body, of size to fit over the body as stated, but similarly constructed, may be employed as a lid for the box; and, when the two parts are soldered to each other, a closed box is provided, which will be found service able for oysters and other commodities.

The blank may have a piece, (shown by the dotted lines h,) which, when the body of the box is constructed as stated, will constitute the lid of the box; but, if desired, a separate piece maybe employed for the same purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The box A, having its corners united by the diagonal or triangular folds II, which project into the box, and are continuous of the sides thereof, substantially as and for the purpose set forth.
