"SUGAR-WAGON Box.,v

SPECIFICATION forming part of Letters Patent No. 530,439, dated December 4, 1 894.

To all whom t may concern:

Be it known that I, GEORGE W. MILLER, a citizen of 'the United States, residing at Kalamazoo, county of Kalamazoo, and State of Michigan, have invented a new and useful Sugar-Wagon Box, of which the following is a specification.

This invention relates to that class of sugar wagon boxes which are made of strips or pieces of sheet metal which have been heretofore fastened together at their meeting edges in different ways, which have been found obj ectionable principally owing to the labor and expense required in their production.

The object of this invention is to simplify and cheapen the construction 'while retaining the required strength, and to add to the appearance and utility, by means of a new plan of forming and securing these meeting edges.

A further object is to strengthen the upper flangededge of the box by means of a metal hoop or band right angled or nearly so in cross section. t

1n the drawings forming a part of this specilication, Figure l, is a side elevation; Fig. 2, an end elevation; Fig. 3, a cross section enlarged,taken on line 2-2 in Fig. 1, looking from a point at the left; Fig. 4, a cross section in enlarged perspective taken on line 3--3 in Fig. 1, looking from a point at the left; Figs. 5, and 6, sections on line 3--3 in Fig. l, showing the shape of the meeting edges of the metal before being attached together; and Fig. 7 shows the seam in Fig. 4, with its furrow exaggerated.

In the construction of the box as herein illustrated, three pieces of sheet metal are employed, two pieces A, for the sides, and one piece B, forming the two ends and bottom as an integral whole. The piece B, is cut inthe shape at each end as shown in Fig. 2, being widest at the extreme end and converging at the edges toward the center integral portion forming the bottom, which center portion is of course all the way of a width. This integral bottom and end piece B, is provided with an interior rib U, at each side, a little removed from the edges and extending from end to end of the piece B--that is, after the piece B, is bent into its somewhat U-form Application tiled May 5, 1894. Serial No. 510,240. (No model.)

flaring at the top as in Fig. 1, these ribs extend across the bottom and up each end of p the box, Figs. 2, 4, and 5.

By making the ends and bottom all of a single piece B, the box has noprojecting ange or seams on the ends at the lower side, which facilitates handling and removal of the contents. Still if preferred the bottom and ends may be made of different pieces.

t The side pieces A, are made widest at the top, converging at the ends toward the bottom, and rounded at the lower corners, as in Fig. 1.

The edges of the side pieces A, at the ends and lower side, are iirst` bent outward at an angle as at D, Fig. 6, and the side edges of` the bottom and end piece B, are rst bent upward at an angle as at E, in Fig. 5. The side pieces A, are then placed within the side edges of the piece B, with the bend of the angled edges D, resting on the outer side of the ribs C, of the piece B, and then the angled edges E, are folded over onto the angled edges D, of the side pieces A, and pressed hard by a suitable tool or machine which indents together under pressure both the angled edges E, and D, and that portion of the metal piece B, which is beneath them. Thus is formed a threefold outwardly projecting seam continuous from the top at one end of the box, down over the rounded corners, across the bottom and to the other end. This indenting of all the folds or members of the seam consists in a continuous furrow lengthwise of the outwardly flanged seam, so that each fold has a furrow registering with the others as at F, in Fig. 4:.

It will be seen that this plan of attaching the meeting edges of the metal pieces is simple, perfectly strong, making a tight joint,

and that the ribs C, are not only employed to` ioo to confine the upper ange of the angled hoop I, Fig. 3. This reinforces the rim of the box, while the lower flange of the hoop confines and reinforces the body of the box at the top, and also strengthens the upper flange of the hoop against a downward pressure.

While I design my invention as especially applicable to sugar Wagon boxes, it may be 'applied to any box, dish, vessel, or other article for which it may be deemed suitable; and While I prefer to employ the interior ribs C, referred to, for the reasons given, they may in some instances be' dispensed with.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. A sugar Wagon box or other vessel, made of pieces of sheet metal, one of the meeting edges of said pieces being flanged outward, the other provided with a rib against which the bend of said flanged edge rests, the edge beyond the rib, of the piece bearing said rib, being folded over onto the inside of the seam and confining said flanged edge of the other piece, the three members of the seam having longitudinal, central, registering furrows indented therein under pressure together without the plane of the general surface of said members, substantially as set forth.

2. A sugar wagon box or other Vessel, having a hoop right angled in cross section, the lower flange thereof confining the body of the box at the top, and the upper flange of said hoop being confined by the outwardly flanged rim of the box folding over it, substantially as set forth.

3. A sugar wagon box or other vessel, made of pieces of sheet metal, one of the meeting edges of said pieces being flanged outward, the other meeting edge being folded over onto the inside of the seam and confining said flanged edge of the other piece, and the three members of the seam having longitudinal,

central, registering furrows indented therein under pressure together Without the simple curved surface of said members, substantially as set forth.

In testimony of the foregoing I have hereunto set my hand in the presence of two witnesses.

GEO. W. MILLER.
