useful Improvements in Folding Boxes, of

which the following is a specification.

This invention relates to improvements in folding boxes especially adapted for use as cracker boxes and also adapted for other .nses and it consists in the construction, com-- binatidfri and arrangement of devices hereinafter, described and claimed.

In the accompanying drawings, Fi ure 1 is a perspective view of my improved folding box, showing the same set up. Fig. 2 is a vertical transverse sectional view of the same, taken on the plane indicated by the line a-a of Fig. 1. Fig. 3 is a detail horizontal sectional view of the same, showing a portion of oneof the end walls, a portion of one of the side walls and alsoshowing the devices which form a corner joint between said walls. Fig. 4.- isa vertical detail sectional view, showing a portion of one of the sidewalls, a portion of one of the end walls corner joint between said walls.

and also showing the devices which form the vertical longitudinal sectionalview of my improved folding box, showing the" same set up, taken on the plane indicated by the line 79-?) of Fig. 2. Fig. 6 is a simllar view, showing the same folded; Fig. 7 is a vertical transverse sectional view of the same,

showing the box folded. Fig. 8 is a detail horizontal sectional view of a portion of one of the front walls, showing the means for detachably connecting the top thereof. Fig. 9 is a detail section on an enlarged scale showing a portion of the wall 3, one of the recesses in its upper edge, one of the loops which depend from the top and one of the pins which lock such loop in such recess.

My improved folding box comprises the bottom 1, the end walls 2, the side walls 34 and the top 5. Metallic straps 6 are secured transversely on the bottom near the ends thereof. Similar straps 7 are secured to the inner sides of the end walls 2 at their lower edges and the said straps 6 and 7 are provided with co-acting hinge members whereby said end walls are hinged to the bottom and are adapted to be folded inwardly thereon, as shown in Figs. 6 and 7. Metallic angle straps 8-'9 have lower horizontal wehs secured longitndinalllon the Fig. 5 is a bottom near the sides thereof. The vertical webs of the said angle strapsare of unequal height, that of the strap 9 being higher. The side wall 3 is hinged to the vertical web of the angle strap J by means of a metallic strap 10 which is secured to the inner side of said side wall at a distance from the lower edge thereof corresponding to the height of the vertical wall of such angle 'strap' 9. The side wall 4 is similarly hinged to the vertical web of the angle strap 8 by a metallic strap 11 which is secured to its inner sideat a distance from its lower edge corresponding to the height of the vertical web of such angle strap 8. Ilence the said walls are adapted to be folded over the bottom and over the end walls 2, as shown in Fig. 7 to elfect compact disposition of the walls of the box and enable the same to be folded into small compass.

' On the upper edge of the wall 3 is secured the longitudinally disposed guide strap 12 provided near its ends with oil'set portions 13. The top 5 is provided on its under side near its ends with transversely disposed connecting straps 14: which extend through said ofi set portions 13 of the strap 12 between the latter and the upper edge ofthe wall 3 and have their ends "connected to the side edges of the top, as shown in Figs. 2 and 7. Each of the connecting straps 14 is provided at one end with a down turned, doubled, substantially Ushaped portion, forming aloop 15. The side wall 4- is provided in its upper edge with recesses 16 to receive such loops. Straps 17 of metal are secured on the outer side of the wall 4 at the upper edge and near the ends thereof cover the outer sides of such recesses 16 and have tongues 18 which bear against the inner sides of such recesses and are doubled over the edges of the integral portions between said rec'csses and the inner surface of such wall. The

loops 1!) of the connecting straps 1-1 are adapted to be placed in the recesses 16 and pins '19 may. be inserted in openings in such wall 4 through the recesses 16 and through the bights of the loops 15 to co-act with such loops in looking one side of the top to the wall 4, as shown in Fig. 2. By first removing the pins 19, and then partly lifting the front side of the top to clear the loops 15 from the inner walls of the recesses 16. the top may be readily detached from the wall 4. as will be understood and therea t1 or pushed rcarwardly fOIflthQ pin'pose presently described. q-hc ios guide straps l2 and the connecting straps 14 form slidable connections between the top and the wall 3 to enable the top to be moved over the box or be pushed rearwardly there from until the loops 15 ot' the connecting straps H reach the oti-sets 13 of the guide strap 12, when such loops and the oft-sets of such guide strap will enable the top to be turned as up n a hinge, to a position parallel with the side all 3, as shown in Fig. 7. The ends of the top 4 are here shown as provided with reinforce straps or plates 20 which are U-shaped in cross-section.

Each end wall 2 is provided 311 its vertical edges with recesses 21 which extend from nearly the upper side thereof to nearly the lower side thereof. In the shoulders 22-23 formed at the upper and lower ends of said recesses arc vertical openings 24.- which are here shown as lined by lneans'of sheet metal tubes 2-5. The openings in the side wall 3,

in which the pins 19 are placed, are also shown as lined by sheet metal tubes 26.

Each side wall 3-4 is provided on its inner side at its ends with reinforcing plates 27 each of which is bent to form a doubled inner flange 28, a loop 29 to engage one of the recesses 21 of one of the end walls 2 and an outer portion 30 to extend around the edge and to the outer side of said wall. The end portions of the said straps 27 are extended and bent over the upper and lower edges of the side walls, as at 31. When the box is set up aud the loops 29 of the straps 27 attached to the side walls have been insorted in the recesses 21 of the end wall they cause the flanges :28 of such straps or plates to bear against the inner side of such end walls. Pins 32 are inserted in the bights of such loops and in the coincident openings Q-t at the upper and lower ends of such recesses 21 to detachably secure the side walls to the end walls and hence firmly, yet detachably. secure the corners of the box. hen the box has been folded. as shown in Fig. 7, and disposed compactly, the same may be secured by a wire 33 passed around the same longitudinally and transversely and having its ends connected together, as at "he box thus constructed is exceedingly strong and durable and may be readily set 1p for use and folded compactly when empty for storage and shipment, and when folded may be shipped from one point to another at slight expense owing to the compact. disposition of the parts thereof which enables a number of boxes to be placed in a comparatively small space.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is':

1. A folding box comprising a bottom, end walls hinged thereto for folding on the same and provided with recesses in their side edges, side walls provided on their inner sides at their ends with plates, such plates provided with inwardly extending flanges to bear against the inner sides of the end walls and with similar flanges to enterthe said recessesin the side edges of said end walls, a top connected. and foldable on one of the side walls and hinges connecting said side walls to the bottom, the said hinges of the respective side walls having extended leaves of unequal length adapting one-of said side walls to fold on the end walls and the other side wall to which the top is con- 'nected to told on the first mentioned side wall, substantially as described.

'2. A box having converging walls, one provided with a recess in one edge and the other having a plate 011 its inner side opposed to said edge, said plate having a doubled portion forming a flange to enter such recess, a doubled portion forming a flange to bear against the inner surface of the recessed wall and further provided with an extended portion bearing on the end of the wall to which such plate is attached and a further extended portion bearing against the outer side of such wall at said end.

3. A box having converging walls, one provided with a recess in one edge and the other hating a plate on its inner side opposed tosaid edge, said plate-having a doubled portion 'l'orn'ling a flange to enter such recess and a doubled portion forming a flange to bear against: the inner surface of the recessed wall.

In test imony whereof, I a'fiix my signature in presence of two witnesses.
