Application filed April fi, 1911. Serial No. 618,990.

17 all h 0m it may concern I Be it known that 1, ROBERT J. STEWART, acitizen of the United States of America, residing at Mount Clemens, in the county or 3; Macomb and State ofMichigan, have incover portions raised; Fig. 4 shows a redry o goods;v slices, stationery,;. inpfact any vented certain new and useful Improvements in Shipping-Cases, of which the following is a specification; reference being had therein to the accompanyingdrawings.

This invention relates to packing or shipping cases, and it has for one of its objects the provision of an article of this character which may be built up from a single piece of sheet metal, and which possess great rigidity.

The invention has "furthermore for its object the improved construction of the blank from which the case is built, so. that a large number of these blanks may be stacked together to form a comparatively small pack- Further objects of the invention will hereinafter appear and be particularly defined in the claims.

The invention has been clearly illustrated in the accompanying drawings in which similar characters denote similar parts, and in which- Figure l is a perspective view of the blank from which the case is to be built up, substantially in a series of successive steps which are shown in the next following figures of-which Fig. 2 illustrates the blank with its ends raised; Fig. 8 shows the front in position; Fig. l illustrates the back and movable partition adapted for use in my improved case; Fig. 5 is the case complete and closed: Fig. 6 is an edge view of a portion of the blank as a in Fig. 1, on an enlarged scale; F ig. T is a section on line 7-7 of Fig. 1; Fig. 8 is a top-view of corner 3) of Fig. 3; Fig. 9 is a horizontal section on line 9-9 of Fig. 3; Fig. 10 represents a fractional top view of the corner '0 of Fig. 5; Fig. 11 is a vertical section on line 11, 11 of Fig. 10; Fig. l is a vertical section on line 12, 12 of Fig.- 5; Fig. 13 is a similar section on line 13. 13 of Fig. 5; and Fig. 14 illustrates a modification of the interlock between a pair of united case-sections.

The particular object of the present invention is: to provide a metallic shipping case or box. oi large sizegto. replace the wooden cases-generally used for shipping bulky merchandise which is generally packed in strong cases. My. improved case contains several advantageous features not I {found in the cases in ordinary use, as for instance it has greater strength in every way; it is lighter in weight, it is practically sealed against damage by rain snow or dirt; it can be sent to the shipper in flat condition; it takes less outside room or space for the same cubic contents; it will not burn;

it permits goods to be packed so as to have an air-space all around them, without mak ing any special provisions therefor; it is a one-piece device which does not require any screws nails, clips or other extraneous fas tening means; it can be built up into b0X- form in less time than it takes to assemble a wooden case; and it can be repeatedly used without requiring -new parts. It is, of course, evident that the construction of the metallic case must be in accordance with. its general dimensions and the purposes for which it is to be used, and I have illustrated in the accompanying drawings a three foot shipping case for comparatively-heavy merchandise the strengthening ribs being so disposed and interlocked that the case will sustain its handling during transit without danger of opening at its oints.

Referrin first to Fig. 1 it will be noted that the blank consists oi the several in closing members in one single unitary structure, as for instance the bottom B, the front wall F, rear wall R, cover C, and'endwalls E E. The blank has a series of ribs 20 formed by crimping the sheet-metal along those lines substantially in the manner shown in detail in Fig. 7, the crimps being closed tightly together ,to constitute practically a double-strength braceniember or rib against strains which would tend to bend or buckle on lines parallel with the edge a (see Fig 1). Now, inasmuch as each of. the ribs 20 is cut at each line 20 of the bend or junction between the adjacent sections C -R-B-F, it follows that these sections when bent into box-form as shown in Fig.6,

the corners thus formed will naturally reblank-sections are then bentat right angles, both rib-ends will: becomeiwedgedg and .inter-..

locked-,; and F while there appears inn means for reventinsisreopening.cog: enlargingthe as s im.

enacts with ran 4 in a r the 1m to nels pe sec'f'ons 1 d over the side-cc of the he placed me Q and of l-sections when the latter are in their vertical positions, and these parts may be locked together by tabs 25 formed on the 1B'tll3t1-l36lll5 21 ot the sections and Fund adapted to be passed throhgh slots in the end-sections :5) l3, and bent over the inner races thereoi as shown at 25 in. 9. Attention invited to the fact that in the present instance each end section (E, E) is provided with ribs 2?, 28 formed in the same manner as above described, so that the end-sections will be eiiiciently braced.

ilk-leans are provided iior holding the several rib-crimps in closedtogether condition, these means consisting preferably of por tions of the ribs themselves as, for instance, is shown in Figs. 6 and l, in which a portion of the extreme rib-end is cut to form a lip mar l are adaned to 30 which may be bent sidewise into flat con.-

tact with the body of the section, after which the connection or joint is proof against being pulled apart by ordinary strains. The same construction applies to the extreme ends of all the ribs of the device.

The end-sections E E, are provided with tabs 31 which, when the box is ready to be closed, will be in position to pass through slots or apertures 32 (see Fi 4:) provided therefor in the side edges of the cover section (3, whereupon they may be bent around the cover edge as shown at 31 in Figs. 5 and 12, thus holding the cover down at substantially central points of its sideedges. The front edge of the cover is provided with slots 33 (see Figs. l, 10 and 11). to receive the projecting ends 3% of the ribs of the front-wall section F, the organization being such that these ends are in close contact with the horizontal ribs of the cover, so that, if now the outermost edge of these projections are bent over the cover to pass overthe adjacent rib thereof, a very strong and close joint will be obtained along this front edge, and the parts will also be interlocked against spreading of the ribs.

.ie chautherein by channels or grooves as indicated riously described. inasmuch as i case, and that tacit. separate from each tions lO (see t) w placed into the case an progressively shown in liigs. 1 to 5 in-.

elusive of which 1 illustrates the blank substantially in its normal. condition. In 2 the endswzlls l1, E have been bent upwardly. Fig. shows the front wall raised, lshows the double rear section (comprising the rear wall it and cover C) also raised, the cover 0 being still open and permitting access to' the interior of the case to clench the inner tab-ends of the front and rear walls, and also to load the case with merchandise, after which the cover may be bent down and locked by the tabs and 31 which constitute the final. closing devices. and may be soldered if desired, thus rendering the case proof against thieves.

As will be seen, the ribs for the case are provided while the inclosing walls are in the blank form, thereby enabling the ribs of the strip which forms the front, bottom, rear and and cover walls to be made by crimping the entire strip and not the sections sepa rately, the result being that the ribs are formed at a minimum expense, the blank simply being made of a sufficiently greater width to provide the material for forming the ribs, and at the same time provide for a relative rib arrangement in which a series of ribs (those formed 'by the cutting of a single rib of the strip) will, when the blank operation, not materially affecting the general continuity in length of the series of ribs, so that when the case is folded, there will practically be a rib continuous throughout the four walls, these ribs acting to brace the case against collapsing in one direction, the bends or folds acting in this respect in the opposite direction.

Many changes may be made in the general organization or union between the several members of my improved device with out departing from the spirit of the invention, particularly in the rib-formation and the interlocking union between the adjacent members, and it is furthermore understood that rib-projections similar to those on the' front wall F may be provided on all the ribs where a close and firm joint may be deemed expedient, especially in connection.

with the ribs 27 of the ends sections E E, which may have projections 27 adapted to pass through apertures as shown at r, in the adjacent sections R, F respectively.

I claim v 1. A packing case comprising a pair of foldable adjacent wall sections formed of a single piece of sheet metal, each of said sections being crimped to form closed-in ribs traversing both sections, said ribs being cut at the fold line, adjacent rib ends being moved out of longitudinal alinement to permit folding of the sections with the continuity of the rib line of the folded sections substantially maintained.

2. A packing case having one or more of its inclosing Walls crimped to form inwardly-projecting ribs, means for holding said rib-crimps against opening, and a partition plate having channeled side edges deof said sections, said ribs being cut at the fold line, adjacent rib ends being moved out of longitudinal alinement to permit folding of the sections Without materially afl'ecting the continuity of the rib line of the folded sections, the edge of one end-section overlapping the margin of the opposite end-section, and means integral with the first named section for holding said sections in assembled position.

4. A packing case comprising alined adjacent wall and cover sect-ions formed of a single piece of sheet-metal, each of said sections being crimped to form inward ribs traversing all of said sections, said ribs being cut at the fold line, adjacent rib ends being moved out of longitudinal alinement to permit folding of the sections without materially aifectingthe continuity of. the rib line of the folded sections, the margin of the cover-sectionoverlapping the edge of the opposite Wall-section and having slots, and tabs on said wall section passing through said slots and bent over the cover section for holding both sections in locked position.

In testimony whereof I affix my signature in presence of two Witnesses.
