j ment on the paper box patented to me Novem- -ber 16, 1875; and consists in vthe peculiar shape .of the Short-aps at the corners of the box, so as to facilitate the putting together of the box.

In the accompanying drawing, Figure 1 represents a plan view of a box in knock-down form which embodies my invention. Fig. 2 isa partial Section of the same on line as a* of Fig. 1. Fig. 3 is a partial Side elevation of the same, showing the manner of forming or setting up; and Fig. 4 is a side elevation of one of said boxes and its cover as Set up in. form ready for use.

I form the bottom of the box and its four sides of one piece of material, preferably of paper. The general shape of the blank is a designates the bottom of the box.; b b, the iiaps, which, when turned up, constitute the short sides of the box; and c c, the long sides. Upon each end of the long Sides are short corner-flaps d, in which arel short slits e. The contour ofthe flaps-d is as follows The edge f is on a line with the outer or top edge of the long .sides c, and the outer end extends on a line at right angles thereto for about one-half the depth of the sides c, when it runs inward to the slit e, leaving the slitfrom` an eighth to a quarter of an `inch deep, then from the bottom or near the l bottom of the slit e to the near cornerof the `box-bottom a, stopping just a little outside of `the scoring g, as shown.

The remaining side ofthe ap corresponds to the end of the long `side c, and `is connected thereto, theseoring g forming the division-line. rectangular, Substantially as long as the box Theflaps b b are is wide, and as wide as the box is deep, and have vertical slits h h formed in them, the depth of which slits must be fully equal to l thedistancefrom the bottom of the slit e to the top edge of the flap d, and the distance from the ends ofthe aps b to the slit h must be equal to the distance' between the slit e and scoring g, less the thickness of the stock. The blankis also scored at the junction of the bottom and the several sides, andso far as the particular form` of box above described is concerned,.the scorings maybe of any style in common use, and upon either the outside or inside; but I muchv prefer the particular scoring hereinafter described.

These boxes are designed to be made by dies and machinery, and packed for storage and transportation in the tlator knock-down form, so as to occupy but little space until they are about to be used.

To set up the box for use, the end flaps b b are rst bent up at right angles to the bottom. The short flaps d are then bent at about right angles to the sides c c, and the said sides turned up with the flaps d on the outside of the flaps b, as shown in Fig. 3 5 and the corner n of ap d inserted in the slit h, as indicated by broken lines in Fig. 3 ,then the sides c c are brought up at right angles with the bottom, and the flaps interlock at the slits h e, as Shown in Fig. 4, and the box is ready for use. The cover is the same as the box, only larger, so as to Shut over the same. By cutting out a portion of the stock at the corner, so as to form the flaps d, as shown, the box is much more conveniently set up for use than it is when made merely slit at the corners, as

'shown in my former patent before referred to 5 and by making the diagonal cut stop a little outside of the scoring at the corner, ya small portion of the flap closes around the corner at the bottom ot' the box to make it tight, the same as if no portion of the flap had been removed. It should also be noticed that, this box has no ilaps thatare of necessity bent over for forming, or that are tucked through f openings, and bent back after tuckingyfin which class of boxes thin paper only can be Y used but my box has the aps slit only upon one of their edges, and is so arranged that in forming no substantial `bend of the paper or stock is necessary except at the point of the scorings, and that when the-aps are bent up at said point the stock moves only edgewisel in the act of forming, whereby I am enabled to make my box ofthe very stiiest kind of paper known of` which boxes are ever made.

I score my paper box upon the inside and remove a portion of the stock, leaving the scoring g in V-shaped form, as shown in Fig. 2. When bent up into form the side takes the position indicated by broken lines in said tlgure, the two 'sides of the V-shaped scoring meeting' each other on a miter, leaving the outside corners whole and smooth, so that they will not catch upon objects and tear up.

I claim as my invention- In a knock-down box of the class described, the peculiar. shape of the flaps d-to Wit, having the edge Which,vvhe11'set up, is at the top
