Specification of Letters Patent.

Application filed July 5, 1913.

To all whom it may concern:

Be it known that we, JAooB B. CoNovnI: and EDWARD M. PEACOCK, citizens of the United States, residing at Jersey City, in the county of Hudson and State of New Jer' sey, have invented certain new and useful Improvements in Milk-Cans, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

Our invention relates to milk cans and similar sheet metal containers, and has for a general object the provision of a strong, durable oint at the juncture of the body and breast of the can, capable of withstanding the hard usage to which such cans are subjected.

Another object is to provide a joint which will be simple and inexpensive to manufacture, and which will not provide any unevennesses for the lodgment of decayed milk, but will be smooth and sanitary on the interior of the can.

A more specific object is the provision of a suitable and convenient housing for a reinforcing hoop at the joint.

Still other objects and advantages of our invention will appear from the following description.

Joints have heretofore been proposed in sheet metal containers in which the edge of one member is received in a recess formed by a double fold in the member to which it is joined, and such a joint is disclosed in the patent to Samuel C. Davidson, N 0. 417,813, of December 24:, 1889. Such joints, however, have not provided a smooth interior to the container, and are, therefore, not sanitary and suitable for milk can construction; and, furthermore, the oints heretofore proposed have not been sufiiciently strong and durable for heavy milk cans.

In accordance with our invention, the upper end of the body is prowdded with an outward offset, and the breast is provided with a double fold forming an annular recess into which the offset upper end of the body is received, the inner walls of the recess fitting into the offset so as to form a flush interior joint; and, specifically, in the preferred construction, the offset upper end of the body and the inclosing fold fit down upon the inclined wall of the breast.

Still more specifically a reinforcing hoop is provided at the joint which is housed within the outer wall of the recess.

Our invention also includes various other features of construction and arrangements of parts, as will hereinafter more fully appear.

We shall now describe the construction embodying our invention illustrated in the accompanying drawings, and shall thereafter point out our invention in claims.

Figure 1 is a partial central vertical section and a partial elevation of the upper portion of a milk can, showing an interme diate stage in the fOHlfltlOll of our improved joint. Fig. 2 is a similar view showing the joint in its finished condition.

In the illustrated embodiment of our in vention, the breast 1 is provided near its lower end with a double fold forming an annular recess 2 with two inner walls 3 and 4 and a downwardly extending outer wall The cylindrical body 8 is provided at its upper end with an outwardly offset portion 7 forming an annular shoulder 8 of a width substantially equal to the thickness of the two inner walls 3 and 4 of the recess 2, and this offset portion 7 is received in the recess 2, and, together with the inclosing walls 4 and 5 of the recess, fit down upon the frustoconical or inclined wall of the breast 1. The inner walls 3 and 4 of the recess thus fit into the offset and abut against the shoulder 8 and form a flush interior oint, which may be finished with solder to render the joint smooth.

' The method of forming this joint will be understood from Fig. 1. The fold is first formed with the inner walls 3 and 4 of the recess 2 vertical and with the outer wall 5 inclined outwardly, as shown, at substantially the angleof inclination of the frustoconical portion of the breast 1. The upper end of the body 6 is then inserted into the recess 2, and with a suitable tool the two inner walls 3 and 4t and the inclosed upper end of-the body 6 are forced outwardly against the outer wall 5, thereby forming the offset and the shoulder 8, and forming a securely locked and a sanitary joint. To further reinforce the joint and protect it from injury from blows and other rough treatment, we provide a reinforcing hoop 9 about the body 6 immediately below the oifset and the shoulder 8. The outer wall 5 of the recess 2 is of such length that it extends down below the hoop 9, and in the final operation of forming the joint, this outer wall 5 is forced inward about the hoop and forms a housing for the hoop, as shown in Fig. :2. This arrangement of the hoop immediately below the shoulder 8 permits of this convenient housing, and in no wise detracts from the appearance of the can. The joint is sanitary and easily formed, and combines great strength and durability with neatness of appearance.

It is obvious that various modifications may be madein the construction shown in the drawings and above particularly described within the principle and scope of our invention.

Ne claiin 1. In a milk can or the like, a body having an outward offset at its upper end forming an annular shoulder, and a breast provided with a double told with a double inner wall forming an annular recess for the reception of the upper offset end of the body, the double inner wall of the recess fitting into the offset so as to form a flush interior joint at the juncture of said shoulder and of the lower end of said wall.

2. In a milk can or the like, a body having an outward offset at its upper end forming an annular shoulder, and a breast having an inclined wall and provided with a double fold with a double inner wall forming an annular recess for the reception of the upper offset end of the body, the double inner wall of the recess fitting into the offset so as to form a flush interior joint at the juncture of the said shoulder and the lower end of said wall and the upper offset end of the body and the inclosing fold fitting upon the inclined wall of the breast.

In a milk can or the like, a body having an outward offset at its upper end forming an annular shoulder, a breast provided with a double fold having a double inner wall forming an annular recess for the reception of the upper offset end of the body, the inner walls of the recess fitting into the offset so as to form a flush interior joint at the juncture of the said shoulder and the lower end of said wall, and a reinforcing hoop interposed at the joint and housed within the outer wall of the recess.

4. In a milk can or the like, a body having an outward offset at its upper end forming an annular shoulder, a breast provided with a double fold having a double inner wall forming an annular recess for the reception of the upper offset end of the body, the double inner wall of the recess fitting into the offset so as to form a flush interior joint at the juncture of the said shoulder and the lower end of said wall and the upper offset end of the body and the inclosing fold fitting upon the inclined wall of the breast, and a reinforcing hoop interposed at the joint and housed within the outer wall of the recess.

5. In a milk can or the like, a body having an outward offset at its upper end fornr ing an annular shoulder, a breast provided with a double fold having a double inner wall. forming an annular recess for the reception of the upper offset end of the body, the double inner wall of the recess fitting into the offset so as to form a flush interior joint at the juncture of the said shoulder and the lower end of said wall, and a re inforcing hoop surrounding the body below the offset and adjacent thereto, the outer wall of the recess extending over and forming a housing for the hoop.

6. In a milk can or the like, a body having an outward offset at its upper end forming an annular shoulder, a breast having an inclined wall and provided with a double fold having a double inner wall forming an annular recess for the reception of the upper offset end of the body, the double inner wall of the recess fitting into the offset so as to form a flush interior joint at the juncture of the said shoulder and the lower end of said wall and. the upper offset end of the body and the inclosing fold fitting upon the inclined wall of the breast, and a reinforcing hoop surrounding the body below the offset and adjacent thereto, the outer wall of the recess extending over and forming a housing for the hoop.

In testimony whereof we have afiixed our signatures in presence of two witnesses.
