BOX.

SPECIFICATION forming part of Letters Patent No. 391,743, dated October 23, 1888.

Application filed February 15, 1888. Serial No. 264,128. (No model.)

To all whom it may concern..-

Be it known that I, CORNELIUS J. Has imoUoK, a citizen of the United States, residing in the city, county, and State of New York, have invented certain Improvements in Paper Eoxcs, of which the following is a specifica- My invention relates to folding paper boxes-that is to say, boxes which are constructed with integral fastening. devices and cut to the proper form from a single sheet, with creases for folding. When it is desired to use the box, it is folded up into shape and secured by the reciprocal fastening devices at the corners.

The object of my invention is to produce a box of this character which shall have a bet ter and neater corner finish than those in common use, and which shall be simple in construction and easily and conveniently set up or folded into shape for use.

My invention will be hereinafter fully described, and its novel features carefully defined in the claims.

In the drawings, which serve to illustrate my invention, Figure l is a plan view of a box illustrating my invention, the upper half of the view showing one end of the box in its flat state and the lower half showing the other end in its folded state. As one half of the box is only a repetition of the other ha1f,this view serves to illustrate the entire box in its two forms, flat and folded. Fig. 2 is a fragmentary perspective view of one corner of the box, designed to illustrate the fastening device.

It will be understood that the box is cut from a sheet of stiff paper, all in one piece, including the fastenings. Usually it will be cut with a special cutter or die employed in the manufacture of this class of boxes. In the drawings the creases made in the paper along the lines of the bends or folds are indicated by dotted lines, and the slits where the paper is cut through, but no material removed, are indicated by a full black line.

a represents the bottom of the box; b b, the sides, and c c the ends thereof.

. As the box is provided with like fastenings at each corner to connect the side 6 with the end 0,1 will only describe one set of fastenings.

On the box side I) is left a flap, b*, which is separated from the end 0 along the line m, and creased for folding along the dotted line 3 In this flap is a slit, b, along the line of itsjunction with the side b, and a branch slit, 1), from the slit 1). On the box end is left a hook, 9. The crease z for folding the hook isat its junc tion with the end 0.

I11 folding and setting up the box the side and end of the box are folded up, and the flap b and hook 0 also folded along the lines at and 2, respectively. The hook 0* is passed through the slit 2) at the junction of the flap with the side 5 until the notch c at the upper side of the hook, where it joins the end 0, is properly engaged and forms the lock. The hook is sprung in inserting it in a well-known way, and the engagement of the said notch with the end margin of the slit b forms the lock.

It will be seen that my box has no extraneous fastening devices; that the flap and hook are cut from the waste material at the corner of the box-blank, and that both the end flap and the hook fold on the inside of the box and thus give the box a neat appearance externally at the corners.

The box is stiffened and braced at the eorners by the bearing of the lower edge of the flap b on the bottom of the box, as seen at e in Fig. 2, and by the angular tongues g 9 formed by the slits b b. These tongues, one or both, are pushed in by the insertion of the hook through the narrow slit 1), and form angular braces which tend to stiffen and brace the box.

Of course the box may have any proportions, and either of the parts I) or 0 may be considered its ends. I have designated the shorter sides as the ends. The branch slit b may be omitted; but its use will make the cor ner much more rigid, and it also enables the hook a to be inserted the more easily when the slit b is formed without removing any of the material.

In boxes with high sides two or more hooks and their corresponding slits b may be employed. The cover of the box may be made in the same manner as the box, except that it will be a little larger.

I am aware, of course, that a lock somewhat similar to that I employ has been used in the flat side of a paper box, and that the slit in the side of such a box has had abranch slit to enable the hook to be more readily entered; but this construction does not effect the same result as mine, which is to stiffen the corner of the box and brace it. I am also aware that in some forms of knockdown boxes slits have been formed in the creases to receive tongues or flaps,'and this particular feature I do not claim, broadly. In my box the interlocking is effected at the corners, and the corners braced thereby against both internal and external pressure.

Having thus described by invention, I claim- 1. As an improved article of nianulacture, a paper box having on its side an integral flap, b and a slit, I), at the junction of said side and flap, and having on its end a h0ok,c*, to engage said slit 2) and form a lock, substantiall y as set forth.

2. As an improved article of manufacture,

a paper box having on its side an integral flap, b a narrow slit,b, at thejunction of said side and flap, and a branch slit, 1), forming two angular tongues,gg, in the flap,and having on its end a hook,c to engage slit 1), whereby, when the hook is pushed through the narrow slit 2), the tongue or tongues g are made to form a brace, as shown.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

CORNELIUS J. I-IASBROUGK.
