RECEPTACLE AND METHOD OF MAKING THE SAME.

Application filed February 7, 1922. Serial No. 534,646.

My improved receptacle, in a preferred form thereof, is a bilge barrel having metal heads provided with peripheral channels in combination with a paper fibre board or pulp board body formed from strips or ribbons wound in the respective channels and then spirally in oppositely expanding sections whose ends are brought together in a butt joint which is lapped internally by a metal ring or band and externally by a laminated paper ring or band.

The object of the invention is, generally stated, to provide a receptacle that is inexpensive, strong, durable, tight and easily handled,

I by a simple operation.

Characteristic dcsiderata attained are the provision of a receptacle having a paper body, particularly a spirally wound paper body, with a satisfactory head that can be securely fixed therein in tight relation by a simple oporation, and the provision of such receptacle in the form of a barrel with adequate strength at its median section of greatest diameter together with a joint at such section which will remain tight.

In the accompanying drawings, Fig. 1 is a plan of an end of a receptacle embodying improved features of the invention; Fig. 2 is a longitudinal sectional view through the improved receptacle in the form of a barrel in illustration of a preferred form thereof, and Fig. Cl illustrates a central section taken through the dissociated parts of the head.

The invention, in the form illustrated, has the heads 1 provided with the peripheral channels 2, which are conveniently and economically produced from firmly connected conforming bulged circular sections 1 and 1 having the respective oppositely projecting peripheral legs or flanges 2 and 2 provided i with the respective outwardly projecting lips or flanges 2 and 2, these parts being pressed to shape from sheet metal. The sections l and 1 of each head contain the respective registering holes 1 and 1 through which are forced a bushing 3 provided with the flanges 3. The latter bears against the surface of the section 1 forming the inner surface of the head and the sections 1 and 1 are bound together thereby with the provision of a charging and discharging opening.

The body 4 of the receptacle comprises the two sections 4 of frusto-conical form having their sinaller ends locked in the peripheral channels 2 of the respective heads 1 and their abutting larger ends lapped by the conforming interior ring or band 5 and by the exterior ring or band 6, the ring 5 preferably being made of metal with oppositely converging sections to conform with the ends of the body sections engaged thereon as shown.

The sections 4 are formed by first winding paper, fibre board or pulp board, strips of suitable width first in the respective channels 2 of the heads 1 so as to fill such channels, and then spirally to produce the frusto-eonical sections 4, the term paper being used generically to include fibre board and pulp board. The sections thus formed are combined with the ring 5, on which the larger ends of such sections are either forced by a telescoping movement or wound, and the butt joint thus formed is wound with. multiplied laminations 6, the laminations being of the number requisite to provide the necessary strength,

It will be understood that the strips may be treated with an adhesive to bind the circular windings to the heads and together and the spiral windings together, and that the finished barrel may be treated, soaked or painted with water-proofing or protecting material.

It will also be understood that the construction shown, by way of illustrating a de sirable embodiment of my invention, may be changed, as by forming the heads proper of unitary instead of built up constructions and by producing receptacles in the form of tubs with a bottom or single end as by separating the two sections 4* at their butt joint.

IVhile I have shown and described a preferred form of my invention, I do not desire to be limited to the details of construction excepting as specified in the claims,as my invention comprehends broadly the building up of a receptacle body upon a head, with elimination of the usual operations required and defects involved in assembling the heads and bodies or inserting and securing heads in bodies as previously practiced.

Having described my invention, I claim 2- 1. A receptacle having a head provided with a peripheral channel and a spirally wound body provided with an end comprising a flat helix locked in said channel.

2. A receptacle having a body comprising a spirally wound strip 0 Vegetable sheet material with a portion of such strip wound in a flat helix around a head having a peripheral flange interlocked with said strip.

3. A bulged receptacle comprising a head with peripheral locking means forming a channel of greater width than the thickness of said head and a body comprising a narrow strip of sheet material wound on said head in interlocking relation with said locking means and forming a conoidal helix of varying cross section projecting from said head.

4. A barrel having spirally wound abutting sections, means lapping the interior and exterior of the members forming the joint between said sections, and heads forming peripheral channels interlocked with the opposite ends of said sections, said sections having shoulders projecting therefrom and engaged in said channels.

5. A barrel having sectional heads forming Eeripheral flanges and a spirally Wound body aving laminations engaged by said flanges.

6. A receptacle having a metal head comprising a plurality of registering disks provided with oppositely disposed peripheral flanges and a paper body having laminations wound on said flanges.

7 A receptacle having a head comprising a plurality of conforming bulged disks hav ing oppositely projecting peripheral members with flanges thereon forming a circumferentially open channel between them.

8. A receptacle having a head comprising a plurality of conforming metal disks having oppositely projecting peripheral flanges with lips thereon forming a circumferentially open channel, said disks containing registering holes, and a bushing set in said holes.

9. A receptacle having a spirally wound paper body comprising abutting sections havmg shoulders thereon, heads including peripheral channels engaged on said shoulders, and a metal ring Within said body and lapping the joint between said sections.

10. A receptacle having a spirally Wound paper body comprising abutting sections, paper laminations wound on said body so as to lap the joint between said sections and heads forming a peripheral channel for engaging a shoulder in said body, and a ring within said body and lapping the joint between said sections.

11. A rece tacle comprising a spirally coiled strip of sheet material forming a body having a collar projecting therefrom of greater radial thickness than the remainder of said body and a sectional head having radially projecting members engaging said collar between them.

12. A receptacle comprising a head having peripheral members each provided with a radial flange forming a circumferentially open channel and a splrally Wound sheet material body having a flat helical collar engaged between said flanges and filling said channel.

13. The method of making bilged receptacles which consists in providing a head with peripheral locking means forming a channel of greater width than the thickness of said head and winding thereon a narrow strip of sheet material in a conoidal helix to form a body on said head in interlocking relation with said locking means, said body varying in cross section.

14. The method of making receptacles which comprises Winding narrow strips of sheet material in conoidal helixes to form flaring body sections, telescoping a pair of body sections upon a convex ring, and Winding a reenforcing band of sheet material around the joints between said sections.

15. A barrel having a spirally wound body consisting of abutting sections secured by interior and exterior members, and sectional heads forming a peripheral flange for engaging a shoulder on each of said sections.

16. A receptacle including a head having a peripheral flange forming a channel of greater width than the thickness of said head, and a spirally Wound strip of sheet material forming a body having a collar engaging said flange.

17. The method of making rece tacles which comprises winding about a flanged head narrow strips of sheet material in conoidal helixes to form flaring body sections, telescoping a pair of body sections upon aconvex ring, and winding a reenforcing band of sheet material around the joints between said sections.

In testimony whereof I have hereunto set my name this 4th day of February, 1922.

MATHIAS R. KONDOLF.
