MEANS FOR REINFORCING OPEN END OF METALLIC BECEPTACLES.
Specification of Letters Patent.
Patented rep. 19, 1918.
Application filed February 1, 1915. Serial No. 5,374.
L To all whom it may concern:
Be it known that 1, CHARLES F. SCHRINER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Means for Beinforcing Open End of Metallic Recepta-.
cles, of which the following is a specification.
This invention relates to metallic receptacles, and particularly to the construction of the top end of an open receptacle.
Themain object of the invention is to provide-means for strengthening the top rim of open metallic receptacles, such as garbage cans, ash barrels and the like. This class of receptacles is subject to very rough usage, and their upper open ends soon become jammed out of shape due to the pressure thereon when being dumped. To prevent said distortion, the present means for reinforcing the top rim of such metallic receptacles was designed.
Another object of the invention is to so construct the receptacle, that the reinforcing means will not form a shoulder upon the inside of the receptacle to obstruct the free dumpingof its contents, or leave a place for the accumulation of a part of the same.
With the above and other objects in view as will be understood, the invention will be hereinafter fully described with reference to the accompanying drawings, which illustrate a preferred embodiment of the same, and the novel features thereof will be distinctly pointed out in the appended claims.
In the drawings like characters of reference indicate corresponding parts.
Figure 1 is a side elevation of a receptacle constructed in accordance with my invention, certain parts being broken away to better illustrate the same,
Fig. 2 is an enlarged fragmental section of the receptacle before the reinforcing ring is applied, and
Fig. 3 is a similar view to Fig. 2, with the reinforcing ring in place.
Referring to the drawings '1 represents a metallic receptacle having a bottom of ordinary construction andan open top end. The upper peripheral edge of the receptacle is bent outwardly as shown at 2, then downwardly at 3, and finally rolled up as ate. The rolled up portion 4 preferably terminates short of the outwardly bent portion 2,
thus saving material and labor, and at the same time forming a hollow flange of great strength.
The particular feature of this invention resides in fixing to the above described rolled hollow flange of-the receptacle, a reinforcing ring for furtherstrengthening the rim of the receptacle. Said reinforcing ring consists of a vertical band 5, which is adapted to snugly fit within the open end of the receptacle, and an upper outwardlly bent horizontal peripheral portion 6 for resting upon the outwardly bent part 2 of the hollow flange of the receptacle. This reinforcing ring is fixed to the hollow flange of the receptacle, and an upper outward bent eral portion 6 bent downwardly at 7 for fitting against its side 3, and the edge thereof is turned inwardly, as shown at 8, for binding against the bottom portion of said hollow flange.
In applying a reinforcing ring to the upper rolled flange of a receptacle 1n the manner above described, a shoulder would be formed at the bottom edge 9 of the band portion 5. This would be an objection on account of preventing free dumping of the contents and also providing a lodging place for foul matter. T o overcome this objection, the lower-outer edge of the band 5 is roundcd at 10, and the side of the receptacle is bent inwardly just below the lower edge of the band, thus forming a horizontal bead or ridge 11, which snugly en ages said rounded edge. The inner rounded portion 12 of the bead 11, is made flush with the inner surface of the band 5 of the reinforcing ring, and gradually curves downwardly and outwardly, as shown at 13, thereby providing a smooth continuous surface at this point.
It is thought that the construction and advantages of reinforcing the rim of a metallic receptacle having an open top, as set forth and described, willbe understood Without further explanation. The drawings simply illustrate one way of carrying out the invention, and it will be understood that slight changes may be made in the details of construction within the scope of the claims.
Havin fully described my invention what I c aim is:
1. In a metallic receptacle having an open end, the combination of a band ar-- ranged Within the open end of the receptacle, the band being formed of a flat bar, the lower outer ed e of the band being rounded,
. and the side of the receptacle being bent ina continuouss'urface with the inner flat surface of the band, substantially as described.
2. In combination, a metallic receptacle having an open end,the periphery of the open end of the receptacle being bent outwardly, then downwardly, and finally inwardly and upwardly forming a flange, a band arranged within the open end of the receptacle, the band being formed of a flat bar, the band having a portion bent snugly around said flange, the lower outer edge of the band being rounded, and the side of the receptacle being bent inwardly the same distance as the thickness of the band to form a horizontal rounding bead for engaging the rounded edge of said band and having its inner surface form a continuous surface with the inner flat surface of the'band, substantially as described.
In testimony whereof Iaflix my signature in presence of two witnesses.
