HENRY P. CARRUTH AND WILLIAM C. LUDWIG, OF CHILLICOTHE, OHIO, ASSIGNORS TO THE MEAD PULP & PAPER COMPANY,-OF DAYTON, OHIO, A CORPORATION OF OHIO.

Application filed April 11, 1924. Serial No. 705,821.

' The present invention relates to the packaging and transporting of paper and particularly to the packaging and transporting of sheet paper adapted to be piled or formed into stacks.

One of the principal objects of the present invention is the provision of an improved method of packaging and transporting sheet paper and of an apparatus for packaging,

.10 which apparatus has as one of its principal elements a skid platform upon which the sheet paper is adapted to be piled.

Further objects and advantages of the resent invention will be apparent from the ollowing description when taken in connection with the accompanying drawings, wherein;

Fig. 1- is a perspective view of the platform upon which the paper is adapted to be piled;

Fig. 2 is a perspective view showing the paper packaged and ready for shipment, parts being broken away; and 4 Figs. 3 and 4 show a modified. form of the invention.

Referring to the drawings, 20 designates V a platform, preferably of rigid and substantial construction, which platform has a pair of skids or runners 21 by which the platform is supported at any desired distance above the ground, preferably at such a distance as to permit pushing of an elevating truck thereunder, whereby the platform may be readily elevated and transported. I

The sheet paper is then piled upon the platform to form a stack 22 as shown in dotted lines in Fig. 1 and when the stack or pile of paper has reached the desired height it is preferably enwrapped with a suitable protective covering, as for example thin flexible water-proof paper 23, although it will .be understood that the use of such a .protective covering may be dispensed with if desired. A closely-enclosing confining structure or frame-work 24 for the pile of' paper is then built up upon the platform in order to bind the pile of paper to the platform, and to protect the corners and sides thereof from damage in shipment.

The confining structure consists generally of a series of upright supporting and protecting frame members 25 secured to one side edge of the platform and a second series of correspondingly spaced upright supporting frame members fastened to the opposite side edge of the platform, the corresponding upright supporting members of the two series being connected together acrossthe top of the stack of paper bymeans of the connecting members 26. An important feature of the present invention is the fact that the platform is the same size as the sheets ofpaper to'be packaged, and as a consequence when the upright supporting and protecting members are fastened to the edge of the platform they lie against and closely confine the stack of paper. The connecting members26 together with the upright members 25 and the platform 20 constitute a series of encircling frames which serve to closely confine or bindthe stack of paper on the platform as well as to protect the top and sides of the stack.

, In the preferred form of the invention as shown in Fig. 2 there is an upright supporting and protecting member 25 adjacent each corner of the stack of paper and an inter-' mediate upright member 25 between the corner members, It will be understood of course that the intermediate members may be increased in number as desired or even omitted entirely. Upright supporting members 27 are secured to the end edges of the platform 20 adjacent the corners, these upright supporting members being preferably nailed or otherwise secured to the corner upright members 25 to brace the encircling frames and to protect the corners of the stack of paper. The confining structure 24 is completed by the connecting members 28 which connect 'the several individual encircling frames and which, when taken in connection with the members 26 form a framework over the top of the stack which at least as far as the bottom edge of the g platform and is securely clamped or fastened in position-between the edges of the platform and the

upright members

25 and 27.

In the form of invention shown 1n Figs. 3 and 4 the skid platform 20 is made larger than the sheet of paper to be packaged, and the confining structure 24 is secured tothe upper surface of the platform. The lower ends of the upright supporting and protecting members 25 and 2.7 abut against; the surface 'of the platform and i the uprlght members are held againstthe sides of the stack of paper by means of fastening devices or angle irons 29. Angle irons 29 are fastened to the platform and to the upright supporting members by means of screws, pins or other suitable forms of fastening

devices

30 and 31 respectively, although the fastening devices 31 may obviously be omitted .if desired. The confining structure 24,

and the paper therein may be additionally secured or braced in position upon the platform 20 by means of the bracing or binding frame consisting of a bar 32 which lies over the connecting members 26 and which is bolted. at its ends to the platform by means of the bolts 33. The platform is pro vided at each end with a pair of clamping members 34 which are spaced apart to receive the T-shaped' head of the clamping bolt 33. The bar 32 may be pinned or'otherwise secured as at 35 to the connecting members 26, and when this is done other means for connecting the bars 26 -may be dispensed with.- In the form of the invention shown in Fig. 3 the end encircling frame formed by the connecting members.

26, the

upright members

25 and 27 and the platform 20 are additionally braced bymeans of the diagonal bracing members 36. While both the bracing or securing bar 32 and the diagonal bracing members 36 are employed in the form of the invention shown in Fig. 3 it should be understood that either or both of these may be omitted if desired, and likewise either or both of these are equally adapted to be used with the form of the invention shown in Fig. 2.

- One advantage of using a platform larger than the sheet of paper as shown. in Figs. 3 and 4 is that it is possible to standardize on a number of platforms each adapted to receive paper of several different sizes, thus doing away with a large variety of'platforms. One means by which a platform may be employed for several different sizes of paper is shown in Fig- 4 wherein the platform is provided with several series of holes or slots to receive the particular form of fastening device which may be employed to secure the angle irons 29 upon theplatform. In

, Fig. 4: the platform is illustrated as having three series of holes 37, 38and 39 respectively by which the angle irons may be secured in position to receive various sizes of paper, as shown, for example, by the full line position of the angle irons and the dottedline position of the angle irons. It will be obvious .that the platform may be' provided with any number of series of openings and that by taking advantage of the various possible locations of the angle irons, the platform may be used to accommodate a wide range of shapes and sizes of paper. WVhile the skid platform and confining structure 24 is herein shown as made of wood it will be understood that these parts may be made of metal or any other desired material which may contribute to the lightness, durability or ease of assembly or disassembly of the parts.

After the confining structure 2l is built up around the stack of paper as above described, the paper is ready for storage or shipment as desired. In handling the paper for shipment it is only necessary to push an elevating truck underneath the platform either for loading into a freight car or for unloading therefrom. There being no strain upon the confining structure such as ordinary packing boxes are subjected to when they are raised upon one edge in order to receive a truck thereunder, the confining structure ofthe present invention may obviously be made comparatively very-light, ,being only heavy enough to hold or bind the stack of paper securely to the platform and to protect the edges and corners thereof. From the foregoing description it may be seen that the following advantages are obtained by use of an apparatus constructed in accordance with the present invention.

One advantage resides in the saving in the cost of the package for the paper. The quantity of lumber requiredv being necessarily small, the package is much lighter in weight for any given weight of paper than the usual form of packing case. This results not onlyin a. considerable saving in freight charges but makes it possible with this form of package to load into a freight car a greater weight of paper.

Another advantage which is present particularly in the form of the invention. shown .in Fig. 2 is that when the packages are packed in solid in a freight car, the packages contact with one another and with the Walls of the freight car over the entire height of the package thus preventing any shifting of the paper which would be ruin ous to its quality.

Another advantage is the saving in the handling of the paper both by the manufacturer who packs the paper and by the customer who unpacks the paper. Heretofore it has been customary to construct a solid packing box of the required size and to place thesheet paper therein a little'ata time and finally to nail the cover thereon. This has resulted in considerable waste of inn the paper due to handling in this manner, According to the present invention the paper is pilednpon the platform and since the platform-is out in the open this may be done quickly and Without damaging the edges of the sheets of paper. The stack being formed to the proper size and then covered by the protective covering, the confining structure may be quickly and easily built up about the stack of paper as already described. When the paper reaches its destination it may be unpacked by simply removing the confining structure 24 which leaves the stack of paper upon the platform completely exposed and ready for use. It is not necessary at this stage to unpack the paper a little at a time as in the case of the ordinary packing box. WVhere it is desirable to season the paper prior to its use on the press, as in the case of high grade paper, the paper need not be transferred from the platform to a truck, as heretofore, but may be left on the platform and placed in storage for the length of time required for proper seasoning of the paper, and then withdrawn from storage as required.

From the foregoing it will be evident that the present apparatus and method of packaging and shipping paper effects a great savmg in wastage due to the fact there is less handling of the paper than heretofore, and this is an item of considerable importance in the case of high grade expensive sheet paper.

A still further advantage resides in. the fact that much material is saved by the reuse 'of the platforms which may be returned to their source when empty and again used for shipping paper. The upright supporting members and other parts of the confining structure 24 may also be dis-assembled and returned in compact form to their source and used over again.

While the forms ofapparatus herein described constitute preferred embodiments of the invention, it is to be understood that the invention is not limited to these precise forms of apparatus, and that changes may be made in either Without departing fromthe scope of the invention which is defined in the appended claims.
