PACKING CASE.

Application filed February 12, 1923. Serial No. 618,504.

To all whom it may concern:

Be it known that I, JAMES E. MULcAHY,

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and usefulImprovement in a Packing Case, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to cases which are adapted for shipping heavy articles wherein the principal dimension is the length, such as pressed steel frames, structural steel sections, and the like.

Usually pressed steel frames such as the side bars of an automobile frame are manufactured in one place and are then shipped to another place for assembly. The packing of these frames has hitherto been a serious problem in view of the fact that the usual shipment weighs about three thousand pounds. Accordingly, if the case housing these frames should be dropped even a short distance or if the case should be swung against a solid object, the corners are apt to be displaced with consequent,

damage to the freight. Numerous types of cases have been tried to overcome this diificulty, but heretofore no satisfactory case has been devised.

One of the objects of my invention therefore, is to provide a packing case which is capable not only of satisfactorily withstanding hard usage incident to the handling of the class of freight above described, but also to provide a case which may be readily assembled byun'skilled labor. In addition, my invention contemplates a; packing case having a smooth exterior which permits one case to be closely packed adjacent another, thus facilitating the storage thereof in railway cars, steamships and warehouses, and which also serves as a protective measure for preventing various parts'of the box from being'turned'out of place with subsequent damage tothe freight while in transfer.

I carry out the above objects by providing a case which comprises an inner and outer container which are preferably complementary shaped and in close fitting engagement with each other. The inner container is made of comparatively heavy stock, and the various walls thereof are so positioned with relation to the other walls that the case is prevented from collapsing either longitudinally or transversely thereof while in use. The outer container comprises a sheeting of comparatively light stock and is also so formed as to prevent collapsing of the case. The inner container may be constructed apart from the outer container, but I prefer to make each wall thereof by reinforcing the corresponding wall of the outer container whereby when the walls of the outer container are placed in juxtaposition, the reinforcement forms the inner container.

The preferred form for carrying out the above objects will be hereinafter set forth in the following description which pertains to the accompanying drawings while the essential features will be summarized in the claims.

Fig. 1 is a perspective view of a packing case constructed according to my invention and having a portion thereof broken away to show the inner construction; Figs. 2 and 3 are side and end elevations respectively of one wall; Fig. i is a vertical longitudinal section taken through the case; Fig. 5 is a transverse section taken through the case; Figs. 6 and 7 are side and end elevations respectively for another wall of the case;

and Figs. 8 and 9 are plan and end elevations respectively of the top and bottom walls of the case.

In the preferred form, my invention cinbodies a case having an inner and an outer container, so formed that the inner container comprises reinforcement on the walls of the outer container. Accordingly, the case when assembled comprises a six-sided figure, wherein 10 and 11 constitute the top and bottom walls, 12 and 13 the side walls, and 14 and 15 the end walls respectively. To facilitate production, the opposed walls are similarly constructed, and moreover the reinforcement is so positioned that when the parts are assembled, substantially all lifting stresses are transmitted directly to the reinforcement.

The top and bottom walls being identical, reference may be had to Figs. 8 and 9 where in only one wall is shown. This wall comprises a rectangular member comprising sheathing 20 secured upon an open frame which is spaced inwardly from the marginal edges of the wall. This frame comprises a pair of longitudinal members 21 which are connected by transverse members 22, shown particularly in Fig. 1. Suitable corner braces 23 and transverse braces 24 may be employed" as shown in Fig. 8 for reinforcement purposes. The members comprising this frame are preferably squared stock considerably thicker than the sheathing secured thereto.

In Figs. 2 and 3, the side 12 is also shown as a rectangular unit comprising sheathing 25, which is secured preferably to a one- .pie'ce reinforcing member 26. The member 26-may extend thel entire length of the wall but the width of the member is less than thatof the wall so as to provide shoulders against which the opposed faces of the members 21. of the top;and-bottom frames may engage. The reinforcement 26 may comprise ai plurality of narrow strips placed side {by side, but I prefer toquse a single board because of theqfact that this has been found to produce the most satisfactory results. In Figs. 6 and 7, the wall 14: is-also shown as rectangular inform and formed of sheathing 27- secured to a reinforcing member 28. The width of the end walls is preferably thesame as that of the side walls, while the width of the reinforcement 28 is the same as that of the reinforcement 26 on the side walls. As shownin Fig. G however, the reinforcement 28 terminates short of-the ends of'the wall,thus providing a space against which the ends of the side walls and associated reinforcement may enage.

lVhen' the case is assembled'as shown in Figs. 1, tand 5. the reinforcement on the side and end walls rests upon the reinforcement of the bottom wall and is engaged by thereinforcement'of the top wall. This in effect provides a very rigid-inner container having solid side and end walls and having fabricated top and bottom 'walls which serve to carry the load stresses, and thus to preventdamage to the freight if the load is shifted. This construction provides a satisfactory container for shipping freight of great weight and comparatively small volume. Since the outer containeris formed complementary to the inner container, additionalprotection is provided against collapsing in a direction longitudinally or transversely of the case. Moreover, the sheathing provides a smooth exterior-which facilitates the storage of cases in warehouses, platforms I and transportation vehicles. i

I claim 1.-*A packing case comprising complementary six-sided inner and outer containers, the router-containerhaving a smooth walled exterior, some of the walls'of-the inner container being parallel toand contiguous with the -adjacent W'alls of 'the outer container adjacent walls thereof in engagement with each other, the outer container havinga smooth exterior, and the inner container'having'a fabricated top and bottom-and having smooth side and end walls, said last=-1nentione'd' walls being contiguous with the walls of the outer container.

4. A' packing; case having top and bottom. side and end walls, the-'top and bottomwalls overlapping said walls andhaving a reinforcementdisposed on the inner faces thereof, said reinforcement being spaced inward- 1y from the marginal edges thereof, "each of said wallshaving a continuous-wind contiguous reinforcing member at the inner face thereof, said member being in engagement with the reinforcement on thetop and bottom respectively.

5.A"packing case having-top, "bottom, side and end'walls, the top and bottom having longitudinal and transverse reinforcing members on the inner face thereof, said member being spaced inwardly from the marginal edges of the top and bottom re spectively, the: side walls" having a continuous reinforcing member extendinglongitudinally thereof and of less width than the side--walls;--the top and bottom edges of said last mentioned member being di'sposed intermediate the opposed faces of the :longitudinally extending reinforcing *members of the top andbottom =walls respectively, and the vertical face of said 5 member being contiguous with the adjacent side walls.

'6. A packing casehaving t'op and bottom side' and endwalls, the-top and*bottom'=walls having reinforcement on the -inner faces th'ereof,' each' of the side walls' having a" reinforcing :membe'r extending longitudinally thereof and each of the end walls having a one-piece 1 reinforcing member contiguous with the inner faces thereof, the topy'bottom and vertical edges of said membei*s='being in engagement with the opposed I faces of the reinforcement on the top, bottom and: side walls' respectively.

In' testimony whereof, I- hereunto affix my signature. V JAMES E.- *MULGAH'Y.
