SHIPPING CARRIER FOR ROLLS Filed June 21, 1955 .VE 2UP Patented Feb. 2, 1937 UNITED STATES PATENT OFFICE SHIPPING CARRIERFOR ROLLS Illinois Application June 21,

1 Claim.

This invention relates to a shipping carrier for rolls and more particularly to a shipping carrier for gelatin duplicating rolls.

It has heretofore been customary to use metal, or wood carriers for gelatin duplicating rolls. This practice, however, is relatively expensive, since the carriers are not generally reused but are thrown away.

It is therefore an important object of this invention to provide a relatively inexpensive shipping carrier for gelatin duplicating rolls and the like, wherein the carrier is a tube or core made from fibrous material, such as chip board, straw board, mechanical wood pulp or the like.

It is a further important object of this invention to provide a shipping carrier for gelatin duplicating rolls and the like that can be used at little expense in the shipping of the rolls and that is of such dimensions as to fit over the usual sizes of spindles employed on duplicating ma chines.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying draw- 25 ing.

This invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described.

On the drawing:

Figure 1 is a side elevational view of a shipping carrier for gelatin duplicating rolls with the roll wound thereon.

Figure 2 is an end elevational view of the same.

Figure 3 is a fragmentary enlarged view showing the leader strip of the gelatin roll and a shipping carrier of my invention, preparatory to winding the gelatin strip thereon.

Figure 4 is a sectional View of the shipping carrier mounted on a spindle with the gelatin roll being unwound.

Figure 5 is a fragmentary enlarged sectional view of the end of the leader strip.

As shown on the drawing:

The reference numeral l designates generally a shipping carrier for gelatin duplicating rolls or the like embodying the principles of my invention. As shown in Figs. 1 and 2, a roll ll of gelatin coated strip material I2 is wound upon the shipping carrier III for storage and transportation purposes.

The gelatin strip material I2 is provided with a leader strip l3 of cloth, fiber backing stock, or the like that is secured to the end of the gelatin strip by stitching or by means of adhesive, as indicated at I4, or that is a continuous and integral part of the backing material used as a base for mounting the gelatin of the roll itself. The end of the leader strip [3 is reduced 1935, Serial No. 27,657

toform a tapered portion IS, the leading end of which is suitably reinforced, as by a metal strip l6. O-ne manner of engaging the end edge by the metal strip 16 is illustrated in Fig. 5, wherein the metalstrip l6 and end edge I! are folded about themselves and flattened somewhat together. The reinforced end I8 thus formed is of increased thickness beyond that of the leader strip itself.

The shipping carrier Ill comprises a core or tube preferably formed of cheap fibrous material, such as paper board, straw board, or the like. In dimensions, the core H3 is slightly longer than the width of the gelatin strip l2 so that its ends project beyond the roll II as indicated at I9. The inside diameter of the carrier ID is not less than 1 4 inches, so that it may be slipped over any of the customary sizes of spindles used in rewinding the gelatin roll. The thickness of the wall of the carrier tube or core I0 is preferably between the limits of 1 5 inch and inch, so as to provide the necessary strength and at the same time be comparatively light.

A slot is provided in the carrie ID for receiving the reinforced end I8 of the leader strip. Said slot It] extends longitudinally of the tube or core and its ends are spaced equally from the ends of said core. The length of the slot 20 is substantially the same as the width of the reinforced end I6 and the width of the slot 20 is substantially the same as the thickness of the reinforced end l8. Thus, when the reinforced end I8 is inserted into the slot 20, it fits snugly therein and is held frictionally against removal. It should be noted that the thickness of the wall of the core 90 is such that the reinforced end I 8 may be inserted into the slot and substantially fill the same without projecting into the interior of the core and without forming any projection beyond the outer surface of the core. The reinforced end IB therefore does not interfere with the insertion of a spindle 2| within the core, as is necessary in rewinding the gelatin strip material from the roll ll onto a permanent spindle for use in a duplicating machine.

In starting the winding of the gelatin strip material onto a shipping carrier of my invention, the reinforced end I8 is inserted into the slot 20, thereby centering the strip material with respect to the ends of the carrier. The leader strip I3 is then wrapped around the core l0 and the winding of the gelatin strip material continued to form the roll II.

It will be appreciated that the length of the carrier l0 may be varied to suit different widths of gelatin rolls, but it is preferable to provide the same length of slot 20 regardless of the overall length of the carrier. Accordingly, the length of the reinforced end l8 also remains the same, regardless of the width of the gelatin roll, so that the reinforced end may always be properly fitted into and retained in the slot 20 of any particular carrier.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

I claim as my invention:

In a duplicator roll assembly in which an elongated tube frictionally engages a smooth spindle but is slidable thereon because of the absence of protuberances on the inner face of the tube, an elongated tube of fibrous material, such as paper board, provided with a longitudinally extending slot in the wall thereof and disposed intermediate the ends thereof, an anchor member of substantially the thickness of the wall of said tube laid in said slot, and a roll of gelatin having a leader strip secured to said anchor member, said tube providing a core on which a roll of gelatin is anchored and wound, and providing with said gelatin roll and its anchor an assembly readily slidable over a smooth spindle for use in a duplicator.
