They have been coiled up on an expansible mandrel, and after coiling, have been tied with wire or a metal strap (l in Fig. 10), as is the usual practice. After this, the expansible mandrel has been contracted and the coil removed for packaging.

In making my package, my first step is to provide a pair of skids 2 and 3 in Fig. 3, preferably formed of wood and preferably beveled at their ends as shown. .These skids are fastened in interspaced position by a crossing pair of sheet metal members 4 and 5. Beneath thesesheet metal members I prefer to place bands 6 and I subsequently to be used in the formation of the coil package.

The structure shown in Fig. 1 is preferably formed by securely nailing the members 4 and 5 to the skids'2 and 3. The ends of the members 4 and 5 may terminate at the edge line of the coil which is to be placed on the skid structure, or they'may be so formed as to project beyond the side edges of the coil. Where this is done, in the subsequent packaging of the coil, the ends of the members 4 and 5 may be bent upwardly and will serve in part to give edge protection to the coil. As shown in Fig. 2, the next step is to place over the structure of Fig. 1, a sheet 8 of pro- 9 Claims.

My invention relates to means for packaging and shipping heavy coils of sheet metal. The method and package were devised particularly for use with coils of silicon steel in strip form; but it will be evident to the skilled worker in the art that they are applicable to other coils presenting similar problems.

It is an object vof my invention to provide an adequate, secure, packaged coil for handling, storage and shipment. I

It is another object of my invention to provide an inexpensive package structure, yet a structure which gives adequate protection from the weather as well as from mechanical hazards normally encountered in shipment.

Still another object of my invention is the provision of a packaged coil which can be handled as a unit either by truck means or by means of an electro-magnet attached to a crane or the like.

Still another object of my invention is to simplify the formation of ckaged coils in ways which will hereinafter be s t forth.

Still another object of my invention. is the provisionpf a packaged coil suitable for railroad shipment in a gondola or box car without bracing or the like.

Further objects of my invention will be pointed out hereinafter or will be apparent to one skilled in the art upon reading these specifications; and these objects I accomplish by that certain construction and arrangement of parts, and in that certain method of which I shall now set forth an exemplary embodiment.

Reference is made to the drawings, wherein:

Such a structure is illustrated in Figs. or from the welding plant in the ordinary form. 3 and 4, and may comprise interspaced wooden ible substance desired. I have found it entirely satisfactory. to use a water-proof fabric formed of two layers of heavy paper cemented together by means of asphalt and having between them long, strengthening fibers usually of jute or sisal; but other materials will serve as wrappings such as multiple layers of paper cemented together with a water-proof adhesive, treated cloth or other rubberized fabrics, paper reinforced with cloth, etc.

It facilitates the formation of my package, as will hereinafter be made clearer, if the sheet is of such size as to cover the cylindrical part of the coil and overlap the coil on its top edge. Over the sheet 8 and over the structure of Fig. 1, I prefer to place a resilient and fairly stifl disk 9. This disk may be made of various substances 1n eluding metal; but I have found it entirely satisfactory to use a disk of ordinary corrugated board such as that used in the manufacture of shipping cases. A double lined corrugated sheet cut of circular form, or multiples of this structure, serve very well. The structure of Fig. 2 is now ready to receive the coil.

tective material. This sheet may be of any flex- 'fourths inch stock. One or more of these disks may be used at each position in the'structure of Figs. 3 and 4. The strips I2 may be say threeeighths inch in thickness by one and five-eighths inch wide, and of a length appropriate to the length of the coil. The members 2 and 3 of Fig.

1 may for usual sizes of coils, be cut from 2 x 4 lumber. The coil 13 containing the core structure, is next placed upon the disk 9 in a position which will be clear from Fig. 8. When this has been done, the sheet 8 is folded up around the coil so that the package assumes the appearance shown in Fig. 5. It will now be clear why it is advantageous to have the sheet 8 big enough to cover the outer sides of the coil and extendover the top thereof, since the structure, of Fig-5 is substantially self-sustaining, and no fastenings for the sheet 8 are required during the application of the outer wrapping.

, As shown in Fig. 6, an outer wrapping, longer in length than the coil, is next wound around the coil. This outer wrapping is indicated at M and is preferably held in placeby a band or tie IS. The end of the sheet H which projects above the coil is next neatly folded down on top of the coil as shown.

Finally a disk I 8, similar to the disk 9 may be placed on top of the coil as shown in Fig. 7. Edge protecting means I! may be put in place as shown. These edge protecting means may be solid fiber or other cardboard substance, or may be of metal. The strap members 8 and 1 are next brought up the sides of the coil and across the top where they are fastened in ways known to the art. The coil structure is now complete,

' and ready for shipment.

It will be noted that the coil is completely encased in a water-proof wrapping and that the wrapping is so disposed as to make the coil rainproof. As a consequence a series of these coils may be placed in a gondola car in somewhat interspaced relationship, and transported without difliculty in spite of adverse weather conditions.

handling means 'for bound stacks of sheet metal.v

In Fig. 9, I have shown a type of top structure which while not as neat as the disk [6, is some times found ofadvantage. particularly where a manufacturer is engaged in packaging and shipping a wide variety of sizes or coils. Under some circumstances to attempt to-provide a disk l8 accurately cut for all sizes of coils, would require an uneconomical invento y- The device of Fig, 9 consists of a semi-circular body I8 of corrugated board or other substance, the outer edge portion of which is provided with tabs or ears IS. A pair of these members in opposed relationship may be substituted for the disk It, the meeting edges of the members substantially following a diameter of the coil. The tabs l9 may be bent over the top circular edge of the coil, to a greater or less extent, as may be desired. Any-pair of these members may be employed with coils which difi'er considerably from each other in size, so that the number of different sizes of top members required is greatly cut down. Where any great length of the tabs I 9 is bent over the circular top edge of the packaged coil, it will contribute to the neatness 0f the package to pass a band around it near its top edge, so as to hold down all of the flapsv I9. Where a pair of the members of Fig. 9 are to be used with a relatively small coil, these members may be overlapped at the center-of the package, as will be clear.

Modifications may be made in my invention without departing from the spirit of it,
