SHEET-,METAL REGEPTAGLE.

Application filed December 17, 1921. Serial No. 522,989.

To all whom, t may concern y citizen ofthe United States of America,

and resident of Martins4 Ferry, -county of` 5 Belmont, and State of Ohio, have invented certainjnew `and useful Improvements in Sheet-Metal Receptacles, of which the following is a specification.

This invention relates broadly to sheet-` lo metal receptacles, and it has forits vprimary object to provide a corrugated metal receptacle of the general character or type commonly employed as ash cans, garbage cans and the like, which has a tapered form, rendering it readily nestable for shipping .and storage purposes. y

A further object is to provide a tapered can having its body corrugated for stillening purposes, the corrugations thereof being gradually increased in depth from its upper endto its lower end to provide for absorption of the surplus metal presented as a natural consequence of the gradual reduction of the diameter of the can.

A still further object is to provide a can body of the rcharacter mentioned having the surplus or excess metal of the various corrugations laid over in substantially fiat folds or plaits so as to present asubstantially plain lower edge portion which is adapted both to snugly receive within its embrace the annular flange of the can bottom and also to be closely embraced throughout its exterior surface by a bottomretaining chime ring. y

In describing the invention in detail, reference is ,herein had to the accompanying drawings, in which- Figure 1 is a side elevation of the invention;

Figure 2 is an enlarged elevation of a` fragmentary portion of the lower end of the can;

Figures 3 and 4 are `vertical sections taken on lines 3-3 and 4--4, respectively, of Fig. 1; andf Figure 5 is a horizontal section on line 5 5, Fig. 1.

Referring to said drawings, 1 indicates generally the can body which is formed of a single rectangular sheet of metal. Said body is corrugated vertically from its upper end, or from a point slightly below the usual reinforcing ring 2 provided in the mouth of said body, to its lower end. The' `corrugations gradually increase in depth Be it known that I, HENRY KIELBERG, a v

and correspondingly decrease in width from their upper ends downward to provide for absorption of the metal to the extent that a gradual but decided taper, or reduction in the diameter, ofthecan body is produced" as the bottom of the body is approached.

To 'provide for `close seating/within the lower edge portion of the can body'of the downwardly directed annular flange 3 of a bottom 4, the corrugations-'of said portion `are flattened out, rsuch flattening being effected by laying over the surplus or excess metal in folds or plaits 5, as is best shown in Fig. 5. Internal and external shoulders 6 and 7 are formed aty suitable points in the plaited lower edge portion of the body preferably by pressing in said edge an in-r ternal annular bead 8. The internal shoulder 6 constitutes a rest against which the bottom 4 seats and whereby said bottom is e pevented from being forced upward out of p ace.

Disposed in clamping relation to the lower plaited edge of the can body and `the flange 3 ofthe bottom' 4 is a chime ring 9 by which said parts are securely maintained in proper relation and also whereby suitable reinforcement is aii'orded for the lower part of the can. n Said ring has its inner edgel portion 9a disposed vertically against the inner face of the bottom lange 3, thence extends outward in underlying relation to the extreme lower edges of said flange and the can body, and thence extends upward againsty the outer face of the plaited edge portion of said body and has its opposite,

or outer, edge turned inward and seated in overlying relation tothe shoulder 7.

At a point slightly above the bead 8 each of the furrows of the corrugations is pressed or bulged outward a distance approximating one-half its depth to meet the upper part ofthe indentation made in the production of said bead, as shown at 10. Thus, an approximately flat surface for the laying `over of the folds or plaits is produced.

What is claimed is p 1. A sheet-metal can of the character described comprising ra downwardly tapered body having vertical corrugations which increase in depthand decrease in :width `to ward its lower end whereby reduction in rugationsbeing terminatedabove the lower edge turned inward into overlying edge of said body, the uncorrugated lower edge portion having Vthe surplus metal thereof laid` over in iiattened vplait-like folds and being flexed yat v,a suitable point in internal Vbead form to provide' an internal downwardly facing shoulderand an external upwardly facing shoulder, a bottom fitted in underlying seated relation to the in-` ternal shoulder, and a reinforcing chime ring disposed in supporting relation to said bottom, said ring embracing said edge portion below said bead and having its outer y g relation to the external shoulder; f

2. VA sheet-metal can of the character described g comprising a downwardly tapered body having'vertical corrugations which increase in depth and decrease in width toward its lower end whereby reduction in diameter of said body is effected, said corrugations being terminated above the lower thereof laid over in flat-tened plait-like folds and beinglexed at a suitable point in in-' ternal y bea-d form to provide an internal downwardly facing shoulder and an external ZVupwardly facing shoulder, a bottom litted in underlying Seated relation to the internal shoulder, said bottom having a depending peripheral flange seated against said lower edge portion,y and a chime ring disposed in embracing relation to said edge portion and said flange and having its outer edge seated upon the external shoulder.

In testimony whereof, I affix my signa-` ture in presence of two subscribing wit* nesses.
