PAPER BEGEPTACLE OR CONTAIN ER AND ART OF MAKING THE SAME.

Original application filed January 24, 1920, Serial No. 353,692. Divided and this application filed November 24, 1922.

This invention relates to receptacles or ,contamers made by winding paper or other suitable material on a form or maninner ribs whlch are formed on the inside of the container in the course of winding the strip on the mandrel. These ribs, constituting seats for the closures, are formed by, or reinforced by, strips of metal or other material ofsuitable strength, which are introduced into the wall of the tube asthe winding proceeds and are wound into place with the paper which forms the wall. To this and other ends the invention consists in the novel features hereinafter described.

Referring to the accompanying drawing, Fig. 1 is a sectional elevation of one form of my improved container. For the sake of clearness, in order to show the reinforcing strips as plainly as possible, the several plies or layers of papers composmg the wall oil the container are not indicated.

' Fig. 9 is a sectional view of a form of the invention in which grooves are provided on the outside of the container wall, corresponding to-the ribs on the inside, to receive reinforcing bands;

Fig. 10 is a detail sectional view showing a convenient method of securing a head removably in place.

My improved container may be of any suitable shape in cross section, for example circular, oval, elliptical, or polygonal, but

the circular cross section is in general stronger and is therefore preferred, especially for barrels or drums of large capacity. ln Figs. 1 and2 a container 10 of the cylin drical type is shown, having closures or heads 11, 12, which are held by or against inner circumferential seats consisting of beads or ribs 13, 14:, 15, 16, reinforced by similarly ribbed or corrugated strips of sheet metal l7, 18. As explained hereinafter, these metal strips are wound into the wall of the container as the tubular body is formed, the strips being thus embedded in the wall. lnstead of sheet metal, the ribs may be reinforced by wires of suitable cross section, as round wires 19, 20, Fig. 3, or trianlar wires Fig. 3. If one head is to be permanently secured in place I prefer to use three beads, as in Figs. 1, 2 and 3,- an upper bead 1d and lower bead 16 embracand an intermediate or middle bead 15 en-' gaging a groove in the edge of the head, but one or more of these beads may be omitted. Thus in Fig. l the middle bead is omitted, in Fig. l the middle bead alone is used, and in Fig. 1 only the lower bead is used. In y case, especiall where only one bead is used, additional 'astening means may be employed, as for example screws, as indicated in Fig. 1, connecting the head and wall in any convenient and suitable manner, and the removable head (in general the head which is secured in place after the tubular body oil the container is removed from the mandrel) can be secured in the same or any other way, as by means of a hoop or ring (not shown) inside of the chime and fastened thereto.

The reinforcing members 17, 18 may, if desired, be of perforated or foraminous sheet metal, as in Fig. 6, in which case the adhesive used to cement the turns or layers of paper together penetrates into the holes IOU . and at its inner end is provided with a circumferential groove 24. At its other end its edge is beveled, as at 25, and adjacent to this end is a beveled disk 26 of the same diameter as the mandrel, carried by a shaft 27. The latter is mounted in any convenient manner to permit it to be shifted axially away from the mandrel and then be swung transversely to permit the container to he slipped ofl axially after the mandrel is collapsed. v The head which is to be permanently secured in place is arranged concentrically between the disk 26 and the end of the mandrel and is held frictionally by the firm pressure of the disk. The head and disk thus form in effect a part of the mandrel.

At each end of the mandrel I provide one or more roller heads, as 28, 29, movable radially toward and from the mandrel, and each carrying one or more ribbing 'or finish- 1 ing rollers, as 32, 33, 34. As the paper 36 (under slight tension) is wound on, the roller heads are advanced (as by means of springs, compressed a1r, or other means, not

. shown) and the rollers are caused to bear on the surface. In this operation the cylindric'al rollers 33 hold the paper in snug conformity with the surface of the mandrel, while the ribbing rollers 34, which have their edges beveled or otherwise suitably shaped for the purpose, indent the paper into the circumferential grooves in the mandrel. When a suflicient number of turns or la ers of paper have been wound on, the rein orcing strips 17, 18 are'introduced, as in F' 4. These strips may be just long enougdi to go once around the drum, with or without their ends overlapping, or they may be lon enough to wrap several times, and prefera 1y they are not ribbed or corrugated in advance but are fiat, in which case the desired ribs or beads-are formed by the bead ing rollers 32, 34, while the edges of the strips are held down by the. cylindrical smoothing or finishing rollers 33. Where both kinds of rollers are carried by the same head, the cylindrical or finishing rollers are mounted in sliding bearin springs 38, so that such ro ers may be kept in firm contact with the paper as the wall of they tube increases in thickness. The grooves formed by the ribs) fill-upas the wlnding proceeds,v and in order to kee as fiat as possible the surfaces .next to the ead 37 actuated by (for example the head 12, Fig. 6) the outer rollers 34 are adapted to slide axially on their shaft but are urged inwardly toward the middle roller by springs 39;

As the winding proceeds, suitable cement, glue-or other adhesive is applied, so that the successive layers are firmly united. Ora fusible and waterproof material may be used, as for example paraflin; in which case the paper or other fabric may be impregnated in advance and then heated as it is wound,

so that the layers will unite, cooling means being employed, if necessary or desirable, to facilitate hardening or setting of the paraflin.

When the wall of the tube has been builtup to the desired thickness, the rotation of the mandrel is stopped. The roller-heads are then withdrawn, and the disk 26 is withdrawn axially and swung out of the way. The mandrel being collapsed, the tubular body of the container, with one head or closure in place, can now be slipped endwise oil the mandrel.

As hereinbefore stated, the reinforcing means used is not necessarily a flatstri Other means may be used, as for examp e one or more wires, as in Fig. 3, already described. I may also use a flatstrip wide enough to reach the edge of the tube, especially if the strip is perforated, as in Fig. 6, or it may be wide enough to overhang the edge at either or both ends, as indicated at 18*, F ig. 7. In the latter case, after the wall is built up to the desired thickness the overhanging portion of the stri or strips is bent down upon the outer sur ace of the wall, as in Fig. 8 by spinning or other suitable operation. By making the wallrelatively thin or the ribs relatively deep, or both, the tube may be left with circumferential grooves on its outside, of greater or less depth, in which binding and reinforcing means may be seated, as wires 18", Fig. 9.

One or both heads may be removably secured by the method illustrated in Figs. 1 and 10. n this case the container Wall is formed with an inner bead 13 on which the head 11 rests, and with an inner circumfen ential groove 13 to receive a split ring 13 which is sprung into the groove and overhangs the edge of the head 11 all around. The ring may be stripped or peeled out of the groove when it is desired to remove the head. This groove maybe formed over a rib 40 (Fig. 5) on the collapsible mandrel 21 by means of suitable rollers (not shown) bearing on the paper and the reinforcing strips or wires as the tubular body of the container is formed; or'it may be made by cutting a groove on the inside after the body is removed from the mandrel.

Claims to the art or method of making the container or containers are not asserted in the present application but will be found in my application Serial No. 353,692, filed wardly-extendin January 24, 1920, and of which the present application is a division.

It is to be understood that the invention is not limited to the specific features of construction and manufacture herein described, but can be practised in other ways without departure from its spirit.
