ROWLAND JOHN CURTIS, OF DOVER, OHIO, ASSIGNOR TO THE REEVES MANUFACTUR ING COMPANY, OF DOVER, OHIO, A CORPORATION OF OHIO BOTTOM CONSTRUCTION FOR CANS Application filed November 10, 1927. Serial No. 232,823.

The invention relates to sheet metal cans such as ash cans and the like, and more particularly to the bottom construction of such cans. I

It is common practice to rivet a rolled iron hoop around the lower end of this type of can for the purpose of taking the wear to which such cans are subjected by being dragged across cement floors and the like when filled with ashes or other heavy material.

The object of the present improvement is to provide a bottom construction for such cans in which a rolled iron hoop is provided at the lower end of the can and attached thereto in such a manner as to reinforce this portion of the can and receive wear to which the bottom of the can is subjected without the necessity or using rivets or the like to attach the hoop, thus materially reducing the labor and expense of manufacturing the cans.

The above and other objects may be attained by constructing the lower end of the can in the manner illustrated in the accompanying drawings, in which Figure 1 is a transverse sectional view through the lower portion of a can constructed in accordance with the invention;

' Fig. 2, a detached transverse sectional view of the lower end portion of the can, the bottom and the rolled hoop before the same are assembled;

Fig. 3, a transverse sectional view through the lower portion of the can showing the bottom and hoop placed therein ready for the final operation which attaches the bottom and hoop to the can, and

Fig. 4, a transverse section through the lower portion of a can showing a modification of the invention.

Similar numerals refer to similar parts throu bout the drawings.

In orming the improved can an annulan as at 7, forming a cylindrical flange spaced from the flange 5 and extending below the same, terminating in the angular flange 8.

The flange 7 is of suitable height and circumference to fit snugly within the lower end rof the body 2, between the flange 1 and annular rib 3 thereof.

The rolled iron hoop 9 is provided in its periphery with the annular shoulder 10 adapted to contact with the flange 8 upon the bottom 4, the reduced upper portion 11 of said hoop being adapted to be received between the flanges 5 and 7 of the bottom and having anannular groove 12 in its peripheral surface. 7

In assembling the hoop and bottom upon the body of the can, the hoop is inserted into the annular channel 13 formed between the flanges 5 and 7 of the bottom, the shoulder 10 of the hoop engaging the flange 8 of the bottom when the reduced portion of the hoop is thus seated in this annular channel.

The bottom 4, with the hoop inserted therein, is then placed within the lower end of the body 2 of the can, as illustrated in Fig. 3, 76

the curved portion 6 of the bottom contacting with the inwardly disposed annular rib 3 of the body while the flange 1 of the body engages the flange 8 of the bottom.

By the use of a seaming roller or the like, so

the flanges 1 and 8 are formed into a double seam 14. The double thicknesses of the body and bottom flange 7 are depressed into the annular groove 12 of the hoop as indicated at 15, by means of a roller or the like, and

the inwardly disposed rib 3 of the body is rolled in tightly against the curved portion 6 of the bottom as indicated at 3.

The roller hoop is thus attached to the bottom portion of the can without the expense and labor required by riveting the same, while at the same time it will be seen that flange 1 is provided at the lower end of the this hoop is firmly and rigidly held in place ght with the lower portion thereof extended beyond the bottom of the can so that only the hoop contacts with the floor or ground, whereby all of the wear caused by sliding the can upon the floor when filled is received by the hoop, preventing rapid wear of the bottom of I the can.

'In Fig. 4 is shown a slight modification of the invention, the double seam 14* being pressed into an annular peripheral groove inthe hoop 9, thus obviating the necessity of pressing the metal of the body and bottom of the can into an annular groove such as 12 shown in Figs. 1, 2 and 3.

From the above it will be obvious that the body, bottom and hoop may be quickly and easily assembled in a simple'operation without requiring the labor and expense necessary to riveting the hoop in position.

I claim:

1. A sheet metal can comprising a body portion having an annular flange at its lower end and an inwardly disposed downwardly inclined annular rib spaced therefrom, a bottomhaving a peripheral channel portion adapted to be received within the lower end of the body and to contact with the said annular rib, and provided with an annular flange adapted to co-operate with the flange upon the body to form a seam, the inclined annular rib of the body extending over said annular channel portion for substantially its entire width, the exposed point of contact between the inclined annular rib and the annular channel portion being a substantial distance above the lower containing portion of the can, and a hoop located within said channel portion and having an annular shoulder to engage said seam, said hoop having a peripheral roove into which the lower portion of the ody and the peripheral portion of the bottom are adapted to be pressed, the

hoop extending downward a considerable distance beyond the seam.

, 2. A sheet metal can comprising a body having an inwardly disposed downwardly inclined annular rib spaced from its lower end, a bottom having a peripheral upturned flange terminating in a peripheral downturned flange spaced from the upturned flange, and adaptedto be received within the lower end of the body and to contact with said annular rib, the inclined annular rib of the body extendingover said peripheral up-v turned and downturned flanges for substantially their entire width, the exposed point of contact between the body and bottom portions being a substantial distance above the lower containing portion of the can and a hoop located between the peripheral flanges of the bottom, and having a peripheral reduced portion spaced from its upper edge,

v the lower endportions of the body and downturned flange being united to form a joint at the peripheral reduced portion of the hoop, the hoop extending downward a considerable distance beyond the seam.

3. A sheet metal can comprising a body portion having an annular flange at its lower end and an inwardly disposed, downwardly inclined annular rib spaced therefrom, a bottom having a peripheral channel portion the can, and a hoop located within said channel portion.

In testimony that I claim the above, I have hereunto subscribed my name.
