To all whom it may concern:
Be itknown that I, STEPHEN B. ()oNoVnR, of Jersey City, in the county of Hudson and State of New Jersey, have invented anew and useful Improvement in Rectangular Boxes, of
which the following is a specification:
This invention relates to a new mode of constructing a rectangular box from a single piece of sheet metal, pasteboard, or other material; and consists in producing a quadruple fold at each corner, so that there will be in each corner two triangular pieces or folds placed against each side, forming such corner, as hereinafter more fully described.
In the accompanying drawing, Figure 1 rep represents a perspective View of my improved box; Fig. 2, a plan or top View, and Fig. 3 a side view, of the same. Fig. 4 is a plan viewof the blank hon. which the box is made, showing the'position of the creases, and Fig. 5 is a'plan view of the blank, showing the sides and ends partly turned up duringthe pro- Fig. 6is a plan View of a blank made according to my invention, but withan additional attachment. Fig. 7 is a top view of said blank, partly turned up. Fig. 8 is a side View, and Fig. 9 a top view, of the box made from such blanks.
Similar letters of reference indicate corresponding parts in all the figures.
The blank. A shown in Fig. length of the intended box, with dol' ble the height added thereto, and the width of the intended box will double the height added thereto. The lines a, I), c, and d, in Figs. 4 and 5, show where the blank is bent to form the sides and ends of the box. From each corner of the blank A is-detached a triangular piece, so that the-blank has an octagonal form, as clearly shown in Fig. 4. The irregular pcntagons which are formed by the intersecting lines a b c d at the corners of the blank, are creased each as follows: First, on a line, 6, which divides the right angle where the pentagon joins the intended bottom of the box into two equal parts, said line extending from said angle to the beveled edge at the corner of the box; next,ont\vo lines,fandg, that extend from the ends of the bevel, respectively, to the inner corner of the pentagon, where the same joins the intended bottom of the box. Thus,
a, has the are... lines a (1,?) (1,2) 0,2tlld a c, which form the respective corners of the blank, are also considered as creases inithe mauuiactureof the box, each-colmenpiece has five creases, and is thereby divided into four divisions or parts, which areunialrked. in Fig. 4, h, 1 ,1, and it. In folding or tbfmingthe box from the blank shown in Fig. 4., the crease e at each corner is bent slightly outward, and the creases fand yslightly inward,asindicatediu Fig, 5. W hen, thereupon, the sides l m, and the ends it o of the blank .are turned up, the result will be that the triangular parts hi of each corner will fold against the sides, and the triangular parts j it against the ends of the box, in the nganner clearlyrepreseutod in Figs. 1 and 2 -thqt is to say,-tlre triangles h 'i, which are a will double against the sides, the triangle h comingdmdh'ecteontact for example, and the triangle t covering the triangle it, while the triangle is will coinein direct contact with the end 0, for example, and the triangle j will cover It, all as clearly represented in Fig. 2. By the quadruple triangular folds thus formed within the box at each corner'the corners are properly united without additional fastenin g devices, and-a box of harmonious and salable appearance is pro duced.
From the same blank A a box can also be produced of substantially the same style, excepting that the quadruple triangles on the corner are folded against the outer, instead of the inner, faces of the sides and ends.
I am aware thatboxes have already been prodosed with trian ular toldsprojecting into each corner of the ox, but invariably only with double triangular folds, never with quadruple, fold, l ike mine, the objection to the double folds being that they will overlap each other on the ends or sides of the box whenever the box is made of greater height than half its width or length; while with myi'mproved quadruple fold I can produce a box nearly twice as high as it is wide before the triangular flaps k, for example, that rest against the same end of the box, will come in contact with or over-lap one another. Moreover, lny double fastening produced by the quadruple fold is much more reliable than the single fastening produced by the ordinary double fold."
