This invention relates to the art of packaging and shipping plate or sheet material and more particularly is concerned with the packaging of lacquer plate or other surfaced or polished plate p or sheet metal for shipment.

l-leretofore it has been proposed to ship plate or. sheet metal by providing heavy metal frames in which the metal is laid horizontally in a stack, with means for compressing the stacks and. holdo ing the plates or sheets in position. This manner of packaging plates or sheets although having the advantage of overcoming any relative movement between the individual sheets of a package, as well as including a large number of sheetsin 15 a single package, was undesirable from a commercial standpoint. The sheets tended to stick together. Also the frames were expensive and were, therefore, returned to the shipper, thus further adding to the shipping cost and incurring- 30 boxes were then stacked in position with the aid of wooden bulk-heads nailed to the supporting vehicle so as to form stalls or bins. However, due to the weight of the metal packaged considerable damage to the surface of the metal has been 35 caused by the' packages breaking through the retaining bulk-heads during shipment as occasioned by jars or shocks received in transit. This method was also undesirable from a handling standpoint due to the fact that in filling 40 and uncratlng the boxes the individual plates or sheets were oftenslid. or rubbed upon each other and bent, thereby marring or damaging the sur' face thereof. Also when the boxes were made of cardboard they could bend during handling it and thus the plates were rubbed over each other with resultant damage to their surfaces.

By the present invention all the advantageous features of the prior practices of shipping lacquered, painted or coated plates and sheets are the attendant disadvantages. For example, the present invention provides a package for shipping a large number of plates or sheets, which is desirable from the standpoint of shipping cost, and accomp'ishes I 55 this by means of a cheapand inexpensive name (iii. 20)

upon which the sheets are stacked on edge, as contrasted with the costly and heavy frames heretofore employed. Furthermore, this invention retains the advantages of the above prior methods of handlingsuch material and avoids 5 the scratching, marring and bending of the surfaces which attended both prior methods. This improved package is relatively inexpensive and highly emcient and can be handled mechanically in cars, warehouses and the like as contrasted with prior packages which were in part handled mechanically. Moreover the present invention has the further advantage that a plurality of packages can be placed in a box car and simplyand inexpensively secured together in position within the car. These packages do not damage the car and afford delivery of the material in p perfect condition. 1

The foregoing and other advantages are achieved by the present invention which is described in detail hereinbelow and illustrated in the accomping drawings, wherein:

Fig. l is a perspective view of an improved plate or sheet kage embodying the features of the present invention;

Fig. 2 is a perspectiveview of a unit formed of a plurality of metal plate or sheet packages positioned in a boxcar'which has been broken away to better illustrate the invention;

Fig. 3 is a perspective view of the frame or platform on which metal plates or sheets are placed to make up the package of Fig. 1.

, Fig. i is another perspective view of the frame or platform she in Fig. 3;

Fig. 5 is a perspective view of the frame or platform of Figs. 3 and 4 partially loaded with a plurality of plates or sheets.

e the invention is adapted to be used to package, handle and ship substantially any type of plate or. sheet material, it is particularly 'de- 40 signed for the dling and transporting of thin sheet metal, such as lacquered, painted. or coated plates and sheets having surfaces which are easily damaged and which must be accordingly handled with extreme care. The invention has been illustrated and will bedescribed in connection with the packaging and shipping of lacquer plate which has surfaces that are somewhat sticky and soft when packed and are readily damaged even when fully dried and cured. 5

Referring to the drawings wherein one form of the invention is embodied, the numeral it generally indicates a frame or platform for receiving a plurality of stacks of lacquer plate Ii. The individual sheets of lacquer plate are disposed on edge on the frame and are supported thereby in an inclined position. Each stack of sheets is separately secured to the frame by flexible binding means I2.

The frame l0 includes a base comprising a pair of parallel sled runners or skids l3 upon which a plurality of cross members l4, l5 and ii are disposed. The skids l3 are beveled upwardly at their ends H to permit the frame to be moved along the floor of a supporting vehicle as hereinafter described. Adjacent the ends of each of the cross members l4, l5 and. I6 and extending inwardly therefrom are disposed wedge members l8. Supported by the inclined surfaces of the wedges at an acute angle to the horizontal are top members IS on which the edges of the individual sheets of the lacquer plate may stand. Secured to each of the cross members l4, l5 and I6 intermediate the extremities thereof and extending upwardly from the base are a plurality of pyramidally shaped uprights 20 having converging sides 2|, to which are secured a plurality of slats 22. The uprights 20 and slats 22 form an inclined rest against which the plates may rest when standing on edge on the top l9. These inclined surfaces are normal to the top I 3, that is the angle between top I!) and slats 22 is a right angle, so that when sheets are stacked on edge-on top is and rest against slats 22, the plates will be parallel and the stack will have square edges.

The ends of the

cross members

14 and 16 are provided with inwardly extending slots 23, aligned with slots 24 in the sled runners I 3, and slots 25 in the top 19. cross members l4 and li'and aligned with the end slots 23 are elongated openings 26, the ends of which are in line with the side edges of uprights 20. 3

In making up a shipping package according to the present invention, plates II are stacked on edge on each of the tops l9, and rest against slats 22. Enough plates may be so stacked to cover top ill to its outer edge if desired, but when a small number of plates are to be shipped fillers may be used to fill the space between the outer plate and theends ofslots 23. Each stack is covered with a suitable kind of protective material and individually secured to the frame 10 by any desired means which may for example take the form of the flexible binding elements or straps l2. These straps engage in

slots

23, 24 and 25,

extend along the bottom of the cross members l4 and IE, through the openings 26 and thence parallel to the back surfaces of slats 22 and over the top edge and outer side of stack II. The ends of the straps 12 are secured together as at 30. Edge protectors 3| are positioned between the straps l2 and the edges of the stack to prevent any damage to the stock. The individual stacks of plate secured to the frame "I as described above may be tied together by a tensioned strap 32 which extends around both stacks and under the cross member l5, thereby binding the frame and both stacks into a package.

Several of these packages may be assembled in a group in a car and tied together into a unit. For example, the packages are preferably positioned in a plurality of aligned rows on the floor of the vehicle 34 as illustrated in Fig. 2. Four or more longitudinally extending aligned rows may be positioned in the end of the box car so that the sled runners or skids, as stated above, extend longitudinally of the box car. The plurality of aligned rows of individual packages are bound togr-ther on a, single unit by provision of the cross members of the individual packages.

Midway between the ends of the end bulk-

heads

36 and 31, which normally extend outwardly beyond the endsof the individual packages, as shown in the drawings, so that the bulkheads themselves function as guiding means for the unit if it shifts within the car. The bulkheads are likewise of a height which is approximately the height of the upright members 20 of the frame I0 and, when'the unit is bound up, are spaced from the floor of the vehicle. Flexible binding means or straps 38 are provided for securing the bulk-

heads

36 and 31 together and to bind the individual packages together into a unit. A strap is preferably provided for each longitudinal row of packages, and is tightened and looked as at 39 by any suitable means. It will be seen that by positioning the bulk-

heads

36 and 31 in spaced distance above the vehicle floor 35, the binding straps 38 will not 'only lie tightly against the top of the individual packages but will likewise lie closely and tightly against the under side of the The disposition of the bands 38 in this manner prevents any dislodgment of the individual packages when the unit has been bound or tied up.

- From the foregoing it will be recognized that by the present invention a simplified, practical and inexpensive package has been providedfor handling and shipping plate or sheet material such as lacquer plate and'the like, and moreover; the various difliculties and undesirable features of prior practices have been either overcome or avoided. There is no necessity to return any part of the packaging apparatus or frames to the shipper and the buyer can scrap or salvagethe same if he so desires.

Having thus described my invention in particular detail what I desire to obtain by Letters Patent is set forth in the appended claims 1.
