PATENT GUSTAV A. BISLER, OF PHILADELPHIA, PENNSYLVANIA.

FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 763,142, dated J une 21,v 1904.

Application tiled November 14, 1903. Serial No. 181.183. (No model.)

Tr; nel] 11:/1/0711, t may concern.'

Beit known that I, GUsTAv A. Bisnnr., a citi- Zen of the United States, residing' in the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Folding Boxes, of which the following' is a specification.

My invention consists of an improvement in a folding box, as will be hereinafter described, and pointed out in the claim.

Figure l represents a perspective view of a folding' box embodying` my invention, one end of which being shown closed and the other end opened. Fig. 2 represents a section of a portion on line f1; a', Fig'. 1. Fig. 3 represents a vertical section of the complete box. Fig. e represents a vertical section of a portion on an enlarged scale. Fig. 5 represents a perspective View of the body of the box in folded condition. Fig. 6 represents a vertical section of a portion of the box in folded condition on an enlarged scale. Fig'. '7 represents a vertical section of a portion of the lid of the box.

Similar letters of reference indicate correthe exterior of the end folds D are the staples F, and in the flaps E are openings G, which are adapted to receive said staples F. Then the parts of the box are in assembled operative position, said staples protrude sufficiently to have straps H pass therethrough, said straps being' connected with the end folds D and appear on the exterior thereof, said straps and staples thus connecting the adjacent end folds and flaps and retaining thefsame in the upright position of the box. Vhen the lid J is placed on the body of the box, the ends of the straps H are connected by the strap K, the latter extending above the lid J and forming a convenient handle for the box and serving to retain the lid in position.

L designates the creased lines between the bottom B and sides C, and M designates the creased lines between the bottom B and end folds D, it being noticed that each of said creased lines is formed by compressing' the material of the body of the box along the lines of the creases so as to upset said material, whereby the latter appears on one side as a groove and the other side as a bead, without fracturing the material or injuring the fiber' thereof and in other respects forming a well-defined joint of the order of a hinge which permits of ready folding and unfolding' of the sides, end folds, and flaps and also preserving the strength of the box at the respective creases. On the end folds D are creases Y, which extend parallel with the creases M and are adjacent thereto, it being noticed that the material existing between the creases M and N forms additional folds or walls P, which subsequently occupy the ends of the box when in folded condition, as will be hereinafter more fully explained. As the tendency of the additional walls P is to drop, and thus lower the end folds D, the flaps E on the sides C serve toA brace and hold up said end folds, and then as said iaps and end folds are coupled bythe staples F and straps H, said staples passing through the openings G in said fiaps, as has been stated, the contiguous flaps, end folds, and additional walls are connected as one, thus vastly stiifening the ends of the box.

In order to fold the box, the handle-strap K is removed and the straps H withdrawn from the staples F. The flaps E are then folded upon the sides C and said sides C and flaps E folded on each other on the bottom B. Then the end folds D are folded inwardly over the sides C, it being noticed that said folds turn on the creases M as their hinges, bringing the folds P at the ends of the sides C and flaps E. Then said folds D are folded downwardly on the sides C and turned on the creases N as their hinges, the folds P permitting' the folding of the end folds D flat on the sides C regardless of the several thicknesses of material between the bottom B and the end folds D without straining the creases M and N and without fraeturing or cracking of the side creases M N and folds P, as willbe apparent in Fig'. 6. The box in its folded condition IOO appears as in Fig. 5, when, if desired, the straps H may pass through the staples F, thus preventing opening of the parts, and the body may be placed in the lid J with the l1andlestrap therein, forming convenient package for carrying, packing', transportation, &e., or the body of the box may be liattened out in linoclzdown condition, if desired.

Various changes may be made in the details of construction shown without departing 'from the general spirit of my invention, and l do not, therefore, desire to be limited in each case to the saine.

Having thus described my invention, what C. D. MCVAY, S. R. CARR.
