LEE STURGES, OF CHICAGO, ILLINOIS.

REINFORCED BREAST FOR SHEET-METAL RECEPTACLES.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed April 24, 1908. Serial No. 428,968.

To all whom 'it may concern.'

Be it known that I, LEE STURGES, a citizen of the United States, and a resident of the city of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Reinforced Breasts for Sheet-Metal Receptacles and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification'.

Heretofore in the construction of cans for shipping and handling milk, much "expense has been occasioned as well as loss in injury or destruction of the cans owing to the empty cans being thrown into the car for return to the shipper and the breast portion of the can, or more particularly the somewhat spherically convex upper portion of the can being caved in or indented, or even broken by the rough treatment such receptacles receive. This in practice has been found to be one of the first Lpoints where such receptacles give way, an prove defective, and various attempts have been made to strengthen the breast or top of the can sufficiently to withstand such rough treatment and to prolong the life of the can for the purpose of avoiding also the frequent and expensive repairs occasioned by the structural weakness in this portion. Such devices, however, and ex edients have proven ineffective and have ailed to go into general use because of the considerable expense entailed by the constructions heretofore used for that purpose and because also, of sometimes renderin the can unsanitary by affording a receptac e for dirt.

The object of this invention is to afford a can ofthe class described having a reinforced breast rigidly and permanently secured thereto and united therewith to afford a unitary construction and affording no open joints for bacterial culture or dirt.

It is a further object of the invention to afford a reinforcement for the breast of the can adapted to be .secured in lace without riveting and not only to strengt en the breast of the can, but as well to afford a more rigidk rPhe invention consists in the matters hereinafterdescribed and more fully pointed out and defined in the appended claims.

As shown in the drawings: Figure 1 is a side elevation of a metallic can embodying my invention. Fig. 2 is an enlarged fragmentary section of the same before seaming the neck in place and before tinning. Fig. 3 is a similar view taken after the neck seam is closed and after tinning.

As showiyin the drawings: A indicates the breast of a milk can of familiar form and which is rigidly united to the body a, of the canin the usual or any desired manner and is 4provided above the junction of the body and breast with a bumper bead a, of half round iron or other structural form to afford a reinforcement. Said breast as shown, is somewhat spherically concaved on the inner side and is provided with an aperture at its top to receive the end of the neck C, below the bead c. On said breast beside the lower end of the neck is a reinforcing concave shell A', of heavy gage and which is, as shown, spherically concave, but with less radius than the breast, so that said reinforcing shell bears upon the periphery of the breast at a point intermediate the neck and the bumper bead reinforcement, and affords a slight space between the breast and the reinforcing shell above the lower edge of the latter. When so assembled, and the internal flange or end c of the neck is seamed, or rolled down, as shown in Fig. 3, said reinforcing shell is pinched or pressed downwardly in close contact with the brace for practically its entire inner surface, thereby producing a very fine binding pressure for its entire circumference on its periphery on the breast. The can so formed is then tinned both within and without, the molten tin flowing into the joints and drawing upwardly between the reinforcement and the breast, firml cements or solders the reinforcement and t e bead c, and inner flange c thereto, affording in effect a unitary structure and one in which no aperture or opening whatever between the reinforcement and breast or reinforcement, breast and neck is afforded for contamination.

The handles D, may be secured in any suitable manner upon the breast by riveting or otherwise and, of course, the reinforcement may extend to any desired point intermediate the neck and breast and may be of any desired gage 0r thickness, and, if desired, maybesecuredinplacebymeans of thehandle CIT in addition to the soldering effect due to the tinning and the pinching eHect due to the closing of the seam in the neck.

Of course, numerous details of construction may be varied. i I'therefore do not purpose limiting this application for patent otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described a reinforcing breast for can breasts embracing a layer of sheet metal engaged to the breast at the can neck and covering the breast to a point intermediate the neck and body a bead in the can neck and a flange integral with the neck adapted to clamp the reinforcing breast and can breast therebetween.

2. A reinforcing breast for can breasts embracing a layer of sheet metal of different curvature than the can breast affording a space therebetween and clamped against the breast at the neck and the reinforcing breast sprung to conform to the curvature of the can breast.

3. A reinforcing breast for can breasts embracing a layer of sheet metal engaged to the breast by the can neck and extending down over and fitting to the breast and rigidly secured thereto intermediate the neck and can body.

4. A reinforcing breast for cans embracing a concave disk of sheet metal of less radius than the can breast and ada ted to be sprung inwardly and locked to the breast by the can neck and extending down over and vrigidly secured to the breast by tinning.

5. In combination a can body, the spherically convex breast and the neck ofa spherically concave reinforcing breast having less radius than the can breast and engaged thereto, such engagement serving to spring the reinforcing breast into close bearing with the can breast at the peripheryof the former.

6. A spherically concave reinforcing breast for can breasts embracing a layer of sheet metal adapted to be engaged to the breast by the neck of the can and extendingv down and over and sprung into close fitting contact with thebreast and a metallic lining for the reinforcing breast and can breast.

7. A can embracing a breast, a reinforcing breast and a neck having abead and a fiange for securing the can breast and reinforcing breast rigidly together.

8. A can consisting of a body, a breast, a reinforcing breast of dierent curvature than the breast adapted to conform to the curvature of the breast and a neck securing the-inner ends of the breast and reinforcing breast together.

9. A can embracing a body, a breast secured thereto, a reinforcing breast fitted over the can breast, and a neck for the can provided with a bead to engage on the outer side of the reinforcing breast and protruding into the can, said inwardly protruding end of the neck flanged beneath the can breast.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

LEE STURGES.
