I Application .filed September 22, 1911. Serial No. 650,781.

To all whom it may concern:

Be it known that I, CLARENCE N. FREY, a citizen of the Unlted States. residing at Cintatc of Ohio, haveinvented certain new and useful Improvements in Metallic Shipping-Cases, of which the following is a specification.

My invention relates to metallic shipping cases, and has for its object the provision of a metallic shipping case of novel construction capable of being conveniently knocked down for shipment or storage and of being readily set up for use, and the invention will be readily understood from the following description and claims, and from the drawing, in which latter:

Figure 1 is a perspective view of my improved device in setup relation. Fig. 2 is a horizontal cross-section of the same taken on the line2-2 of Fig. 1, partly broken away. Fig. 3 is a vertical cross-section of the same taken on the line 33 of Fig. 1, partly broken away. Fig. 4 is a plan view of the blank, partly broken away, from which the walls of the shipping case are formed. Fig. 5 isa plan View of the blank, partly broken away, from which the locking angular channeled corner-strip is formed. Fig. 6 is a perspective view of the locking angular channeled corner-strip. Fig. 7 is a detail of a corner of one of the walls, with the flanges bent; and, Fig. 8 is a side elevation showing an enlarged detail of one of the corners of the shipping case in set-up relation, showing the locking tongues in unlocked relation in dotted lines and in locked relation in full lines.

11, 11 represent the walls of the packing case, which may include the sides, top and bottom of the case. These walls have edges of similar form and may be of sizes to con form to the size of the case desired. They are formed up from a metal blank, shown at 12, having endextensions 13. At the ends of the latter there are rabbets 14: for the purpose hereinafter described. The end extensions are bent back toward the body of the blank in the form of return-bend flanges ,15 between which and the body channels 16 are formed. There is a recess 17 at each end of each flange.-

18, 18, represent angular channeled corner-strips, and 19, 19, represent locking angular channeled corner-strips. These corner-strips are metallic corner-strips formed up from blanks of metal. The blank from which the corner-strip 19 is formed up is shown at 20, in Fig. 5. It base pair of tongues 21 at. each end. The blanks from which the corner-strips 18 are formed up are similar to the blanksQO without the tongues. The blank 20 has side-extensions 22 having rabbets '23 at theends thereof, there being a slot 24 between the tongues at each end of the blank. The side-extensions of the blanks for the corner-

strips

18 and 19 are bent back toward the body of the blank for forming return-bend flanges 25 having channels 26 between them and the body of the blank. The corner strips are provided with a longitudinal bend for form'- ing wings 27 which project at right angles with relation to each other and form the corners 28, the strips beingbent for. causing the flanges at the respective sides thereof to approach each other. In practice the angular channeled cornerstrips 18 are of a length to correspond to the length of those edges of the walls of the case with which they coact, less the width of a pair of the wings 27, while the channeled portions of t-he'locking corner-strips 19 are preferably of asimilarlength, these latter corner-strips having an addition thereto, however, the length of the locking tongues at each end thereof.

- In setting up the shipping case, the. sides of the case are preferably set up on edge, with the flanges on adjacent corners at right angles to each other, the flanges at i the respective corners being presented outwardly, the adjacent-flanges of the sides being received in the channels of the corner-strips 18 at the respective corners of the case, and vice versa, the flanges of the corner-strips 18 being received in the channels under the adjacent flanges of the sides.

ing the bottom to the sides to be slipped past the endsof the former, and in turn permitting two of the locking channeled corner-pieces 19 to be slipped past their ends into connecting relation with the remaining flanges between 'the bottom and sides, the tongues projecting beyond the ends of the bottom, as shown in dotted lines in Fig. 8, the tongues being then bent one across the other, as shown in full w lines in Fig. 8, outside the walls, and thereby locking the corner-stripsl9 in place and preventing movement of any of the cornerstrips 18 past the same. The tongues are received in the recesses 17 at the ends of the wall-flanges for avoiding protrusion of the bent tongues and providmg neat, strong and flush-corners for the set-up shipping case. The top or cover of the case is now ready to be put in place; which is done in manner similar to the assembling of the bottom on the sides.

In opening the shipping case it is only necessary to bend back the tongues at one of the ends of .each ofthe corner-strips 19 holding the top or cover in place, when these corner-strips and the corner-strips 18 connecting with the top or cover may be slipped endwise off the shipping case and the tion, what I claim as new and desire to secure by Letters Patent, is:

1. A metallic shipping case comprising walls provided with return-bend flanges at the respective edges thereof which are shorter than the edges on which they are located for forming recesses at the ends of said flanges, said flanges having flange-receiving channels thereunder, and cornerstrips provided with mating return-bend flangesvfor said first-named flanges received under said first-named flanges through said recesses, said mating return-bend flanges having channels thereunder in which said first-named flanges are received.

'2. A metallic shipping case comprising walls provided with return-bend flanges at the respective edgesthereof which are shorter than the edges on which they are located for formin recesses at the ends of said flanges, said anges having flange-receiving channels thereunder, and cornerstrips provided with mating return-bend flanges for said first-named flanges received under said first-named flanges through said recesses, said mating return-bend flanges having channels thereunder in which said first-named flanges are received, and said corner-strips embracing locking cornerstrips having end-tongues arranged for being bent into the longitudinal projections of other corner-strips.

In testimony whereof, I have signed my name hereto in the presence of two subscribing witnesses.
