FOLDING CRATE OR BOX;

To all 'whom fit mtl/y concern: y

Be it known that I, FRANK E. S'rnnnn'r'r, a i citizen of the United States, residing in the city and county of Deliver and State of Colorado, have invented certain new and useful Improvements in Folding Crates or Boxes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to the ligures oi reference marked thereon, which form a part of this specification.

My invention relates to improvements in folding crates or boxes, my object being to provide a construction of this class which shall be readily collapsible, whereby it becomes practicable for the consignee to return the crates or boxes in collapsed form lor reuse in shipping` goods.

My present improvement embodies certain novel features of construction, all of which will be fully understood by reference to the accompanying drawing in which is illnstrated an embodiment thereof.

In this drawing, Figure l is a perspective view of a box containing my improvements. Fig. 2 is a t'ront view in detail illustrating the fastening device. Fig. 3 is a side elevation ot' the same looking in the direction of arrow 3, Fig. 2. Fig. -l is a view similar to Fig. 2, but showing the it'astener in the locked position. Fig. 5 is a sido view of the same or a View looking in the direction of arrow 5 Fig. Ll. Fig. t5 is a side elevation in detail showing the locking arm of my improved fastener. Fig. 7 is a cross section taken through the box shown in its position for use. Fig. 8 is a similar view showing it in collapsed or knock-down form. Fig. t) is a 'fragmentary sectional view on a somewhat larger scale. Fig. lO is a top plan view showing the box in its extended -torni. Fig. l1 is a sectional view oli the same taken on the line 11-1l Fig. 10.

'The same reference characters indicate the lsame parts in all the views.

Let the numeral 5 designate the bottom; 6 and 'l' upwardly projecting stationary side members connected with the bottom; 8 and 9 either side members hinged to the stationary side members 6 and 7 respectively; l() the top member hinged to the side member 8; and 12, l2 two end members hinged to Specification of Letters Patent.

Application filed March 29,

stationary end members 13.

1909. Serial No. 486,458.

The bottom oi the box is provided with a metal strip 'lli which extends upwardly on the stationary side G and 7 as shown at l5 and downwardly on the inside of these members as shown at lb. .\t the upper edge of each oit the members t3 and 7, the material is slightly eutl away to leave elongated bearings 1T which are engaged by links Y1S, the latter also engaging hinge-eyes '19 formed at the lower extremities ot metal strips 2O and Z1 secured to the hinged members 8 and 9 of the box.

By virtue of the elongated bearing 17 for the link 1S, the said link is allowed to travel inwardly from the tfull line position in Fig. S) to the dotted line position in the same figure during the operation of folding the sides 8 and t) of the box inwardly to the position shown in Fig. S. By virtue of this special hinged construction, the parts 8 and t) of the box are permitted to fold inwardly without cutting away any material or weakening` the box where the hinges are located.

The extremity oit each metal strip 20 remote from the hinge-eye 19, is provided with an eye Q2 which projects slightly beyond the adjacent edge olf the box member S and is connected by a link '23 with a hinge 24 of a metal strip extending transversely across the top of the box. The hinge-eye Qdi is located a short distance from thc adjacent longitudinal edge 2t) of: the top of the box leaving a part QT projecting beyond the said eye 2st, to permit the top member 'l0 to fold inwardly llnsh with the inner surface ot the stationary member 'T when the box is in the collapsed position (see Fig. 8).

The extremity of each metal strip remote from the hinge-eye 24 is provided with a hinge-eye 2S, which projects slightly beyond the adjacent edge of the top member l() and is engaged by a link 29 adapted to interlock with an angle link 30 whose body member 3l engages a hinge-eye 3Q formed in one extremity ol the metal strip Q1. The angle link 30 is bent at 33 to form two members 3l and llt which occupy positions preferably at right angles to each other. Pivotally mounted or iulerumed upon the angle member Bil is a locking lever which as' shown .in the drawing 1s composed of an integral piece of wire having a long arm 36 and a relatively short arm 37, the two arms extending virtually at right angles to each other. The wire is bent at the angle of the two arms to 'form an eye 38 through which the extremity 39 of the member 34 of the angle link passes.

in order -to lock the cover in the closed position, the arm 36 of the lever 35 is first passed upwardly through the link 29 (see Figs. 2 and 3). In this event the short arm 87 of the lever projects outwardly and the lower extremity of the link 29 occupies a position just above the short arm of the lever. The lever is then actuated b y throwing its long arm downwardly against the link 29, whereby the free end of the said link is thrown into the angle 40 formed by the two arms 36 and 37 of the locking lever. Then as the downward and inward movement of the lever arm 36 is continued, the lower extremity of the link 29 is carried inwardly and occupies a position in the rear of the lever arm 36 and just below the short arm 37, the latter serving to carry the lower end of the link 29 outwardly when the arm 3G of the lever is manipulated to interlock with the lid of the box.

As shown in the drawing, the metal strips extend entirely around the box near the opposite extremities thereof, thus duplicating the locking devices. strip members and links which have heretofore been given reference characters in connection with the hinge members of the box.

The end members of the box are each hinged to an adjacent stationary end member 13 by means of metal strips 41 secured to each end member 12 and movably connected as shown at 42 with hinged members 33 which as shown in the drawing` are composed of staples driven in to the adjacent stationary end member of the box.

Each end member 12 is further provided with hooks 44 pivotally connected with the member 12 as shown at 45. The hook member 46 of each hook is adapted to engage an eye 47 secured to and protruding from the inner surface of the adjacent side member 8 or 9 of the box as the case may be. These hooks serve to securely retain the hinged side i members 8 and 9 of the box 1n place when the latter is in use, whereby the said side members are prevented from bulging' outwardly.

lVhen the box is in use, the various inembers are in the position shown in Figs. 1 and 7 of the drawing, while when the box 1s collapsed, it is in the position shown in Fig. 8 of the drawing. This collapsed position of the parts is obtained by unlocking the lid,

Adisengaging the hooks 44 from the hinged uside members, folding the end members 1nwardly successively, then folding the side member 8 inwardly upon the end members, then the top member in the opposite direc V,tion causing it to. engage the outer surface 'of the member 8, the edge 26 of the top meme ber being thrown to engagement with the the opposite edge of the top member as nearly flush as possible with the outer surface of the stationary side member 6; after which the hinged side member 9 is folded inwardly on top of the top member (see Fig. 8). l

1n folding the side members 8 and 9 inwardly, it must be remembered that the links 18 are carried inwardly through the elongated bearings 17, until the surfaces of the side members 8 and 9 are brought flush on the inner surfaces of the adjacent stationary side members G and 7 after which the hinged side members are free to fold inwardly to position at. right angles to the respective stationary members with which they are connected..

The folding side members 8 and 9 of the box are provided with reinforcing strips or cleats 48 and 49 which serve not only to strengthen the parts with which they are directly connected, but also engage the folding ends of the box and prevent the latter from moving outwardly due to pressure from within. The stationai y side members (3 and 7 are also provided outside of the end members with triangular parts 50 and 51 which engage the bottom 5 as well as the side members 6 and 7. These parts also strengthen the end members as will be readily understood.
