SHEET METAL BARREL Filed 001;. 24, 1928 Patented Oct. 29, 1929 UNITED STATES PATENT OFFICE GEORGE A. SEXTON, OF WINCHESTER MASSACHUSETTS, ASSIGNOR TO SEXTON CAN COMPANY, INCORPORATED, OF EVERETT, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS SHEET-METAL BARREL Application filed October 24, 1928.

This invention relates to a barrel which includes a cylindrical sheet metal body and a bottom at one end portion thereof. The object is to provide a barrel of simple construction including a cylindrical sheet metal body and cylindrical sheet metal internal hoops or end members imparting great strength to the ends of the barrel, so that the latter is adapted to withstand the rough usage to which ash and garbage barrels, andother like containers are subjected.

Of the accompanying drawings forming a part of this specification- Figure 1 shows partly in section, and partly in elevation, a side view of a barrel embodying the invention.

Figure 2 is a perspective view showing the upper hoop inverted.

The same reference characters indicate the same parts in all of the figures.

My improved barrel comprises an open ended cylindrical barrel body 12, of sheet metal, and two cylindrical sheet metal inter nal hoops or end members at opposite ends of the body. Each hoop has an outwardly projecting annular peripheral inner stiffening bead 13, spaced from its edges, said bead constituting a seat or abutment for an end of the body. The bead 13 defines an inner zone 14, and an outer zone 15 of the hoop. The inner zone enters an end portion of the body and is rigidly attached thereto by any suitable means, such as rivets 16 or electric spot welds. The inner zone is of sufficient width to materially reinforce and strengthen the body. The outer zone 15 projects from an end of the body and constitutes an extension thereof. Said outer zone has an outwardly projecting outer stiffening bead 17, spaced from the inner bead 13, and constituting an end of the barrel.

The outwardly projecting inner and outer beads impart great strength and stiffness to the internal hoops, and are adapted to re sist rough usage tending to distort and indent the end portions of the barrel.

The outer beads 17 have rounded external surfaces, so that they constitute smooth hand grips adapted to be conveniently grasped without injury to the hands.

Serial No. 314,667.

The bottom 19 has a marginal flange 20, interposed between the lower end portion of the body and the inner zone of the lower hoop and attached by the rivets, or other means attaching the lower hoop to the bottom flange 20 and to the body, as shown by Figure 1, the barrel being additionally reinforced by said flange. The inner zone of the lower hoop is designated by 14, to distinguish it from the inner zone 14 of the upper hoop. Said inner zone 14 is offset inwardly from the inner surface of the body 12', as shown, to form an annular space adapted to receive the bottom flange 20, the lower edge of said flange being seated on the stiffening head 13, of the lower hoop. The inner zone 14 of the upper hoop is not inwardly offset like the zone let of the lower hoop, so that the zone 14. bears directly on the inner surface of the body 12, as shown by Figure 1.

Each internal hoop is constructed by bending a fiat strip of suitable width into hoop form, uniting the ends of the strip, preferably by electric welding, to form a joint 22, (Figure 2), and then forming the beads, the bead 17 being preferably formed by a first operation, and the bead 13 by a second operation. The two hoops dilfer from each other only in that the inner zone 14 of the lower hoop is offset inwardly, as shown and described. It is to be understood that Figure 2 shows the upper hoop in an inverted position.

An internal hoop constructed as described, constitutes an article of manufacture adapted for quick and convenient attachment to a body 12 in constructing a sheet metal barrel.

I claim:

1. A barrel comprising a cylindrical sheet metal body, lower and upper internal sheet metal hoops having inner zones within the end portions of the body and outer zones projecting from the body ends, said hoops having outwardly projecting annular inner stiffening beads between said zones seated on the ends of the body, the outer ends of said hoops projecting from the body ends and having outwardly projecting annular outer stiffening beads spaced from the inner beads and constituting the ends of the barrel, and rivets uniting the inner zone of the upper hoop to the upper end portion of the body, and the inner zone of the lower hoop to the lower end portion of the body, said rivets maintaining the inner stiflening beads in contact with the body ends.

2. A barrel comprising a cylindrical sheet metal body, lower and upper internal sheet metal hoops having inner zones within the end portions of the body and outer zones projecting from the body ends, said hoops having outwardly projecting annular inner stiffening beads between said zones seated on the ends of the body, the outer ends of said hoops projecting from the body ends and having outwardly projecting annular outer stiffening beads spaced from the inner beads and constituting the ends of the barrel, and rivets uniting the inner zone of the upper hoop to the upper end portion of the body, and the inner zone of the lower hoop to the lower end portion of the body, said rivets maintaining the inner stiffening beads in contact with the body ends the lower hoop diilering from the upper hoop only in that its inner zone is contracted to permit the interposition of a barrel bottom flange between it and the lower end portion of the body, so that said inner zone 7 is an element of means for holding a bottom.

In testimony whereof I have afiixed my signature.

GEORGE A. SEXTON.
