Specification of Letters Patent.

. Patented Aug. 10, 1909.

. Application filed November 8, 1908. Serial No. 460,921.

Be it known'that I, SAMUEL FRPIINID, a citizen of the United States, and residing at Chicago, in the county of Cook'and State of- Illinois, have invented a new and useful Improvement in Collapsible Boxes, of wh1ch the following is a complete speclficatlon.

This invention relates to improvements in collapsible boxes and more particularly to a collapsible box of that class in which the walls are so connected together that when.

two opposite walls are raised to an upright or open position .the remaining walls will be automatically brought to an upright position.

Heretofore in boxes of this class it has been difficult to so secure the walls in open position that they will not colla se or become disconnected when outward strain or pressure is exerted on the pair "of walls which are automatically opened. This is the cause of considerable annoyance, since if the box is so full that its contents crowd on the walls, the latter will spring apart and produce an unsightly as well as annoying packwalls, and in which means are provided for so looking the'walls' in open position that they cannot be collapsed y outward pres- It is a further object of the. invention-to provide a collapsible box adapted to be easily and quickly set up and the walls thereof locked together on the inner side of the box so that the danger of the locks becoming disengaged by catching on extraneous objects is-entirely obviated.

The invention consists of the matters here- 1nner corner of said portion.

cated respectively by a and a, one"pair of which, as herein shown the side Walls, is adapted to be folded along the lines a vand lie flat upon said bottom when the box is collapsed, as shown in Fig. 1. The other walls a, only one of which is shown, are adapted, when the box is collapsed, to lie in the plane'of the bottom, and when in open position to be folded on the line a Integrally connected to the adjacent ends of the walls a and a, along the folding lines a,a respectively, is the infold, indicatd as a whole by B, and each of which is adapted to fold diagonally on the folding line 12, thereby dividing the infold into a fixed and a hinged portion indicated by bbrespectively. Said fixed portion b of the infold may be rigidly secured to the inner faceof the wall a in any preferred manner but as shown it'is secured thereto by means of a stitch or staple 6 near the portion 5 of said infolds are each provided with an elongated locking slot or aperture which when the box is collapsed lies parallel to the folding line a", as shown in Fi 1,]and when the box is open, is vertical y disposed adjacent the corner of the box, as shown in Figs. 2 and 3.

On the outer or upper marginof the wall a is a locking flap C, which when the box is open, is adapted to fold inwardly on the folding line 0, and over the infolds B. At

The hinged each end of said locking flap is a hook 0',

comprlsing'a point 0 and a neck 0 the latter of which is of a width equal to the length of the lockingaperture b, and the aperture is provided at the end thereof adjacent said flap with a slit 6 through which the point of thehook is adapted to pass. Said slit forms a shoulder b behind which said point engages when in looking position, as shown more clearly in Fig. 3.

When it is desired to erect the box the walls a are turned to an upright position and the hinged portions 6 of the infolds B draw the walls a to an upright position with said portions 6' folded back along the lines 12 upon the fixed portions b,. The looking flaps C are then folded inwardly and the hooks inserted in the locking slots b thereby rigidly locking said flaps to the infolds and preventing the box from collapsing. Inasmuch as said hooks are firmly engaged in the apertures b it is obvious that the wall (1" cannot return to collapsedv position until said hooks are released, so that the danger of the flaps becoming disconnected and permitting the wall to fall is entirelyobviated.

I claim as my invention:

1-. In a device of the class described the combination with a bottom of a plurality of walls hinged thereon, infolds connecting adjacent ends of contiguous walls, said infolds being folded diagonally to provide a fixed portion adapted to be rigidly engaged to one of the walls and a slotted, hinged portion hinged to the adjacent wall and to said fixed portion, said hinged portion having a shoulder intermediate the ends of said slot,

' a locking flap on one of said walls adapted to be folded over said 'infoldand hooks on the ends thereof adapted to project through the slots of'said hinged portions and engage 2. In a device ofthe class described the combination with a bottom of walls hinged thereto, infolds hinged to the ends of opposite Walls and dia onally across the contiguous walls and adapted to be folded back parallel with the latter walls; an elongated locking aperture in each infold, each having a longitudinally extended slit at one end thereof providing a shoulder, a locking flap on said last named wall and adapted to fold over the infolds, and means on the ends thereof adapted to project through said apertures and engage ehind said shoulders.

In testimony wherof I have hereunto subscribed my name in the presence of two witnesses.

SAMUEL FREUND.
