MILK GAN COVER.

NO- 546149,85 Patented Sept. 1'7, 1 895.

UNITED STATES PATENT EETcE.

LEE STURGES, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHICAGO STAMPING COMPANY, OF SAME PLACE.

MILK-CAN'COVER.

SPECIFICATION forming part of Letters Patent No. 546,498, dated September 17, 1895.

Application filed January 2, 1895i To ad whom, t may concern/.1

Be it known that I, LEE STURGES,a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Covers for Milk-Cans and in the Method of Making Them, of which the following is a specification, reference being had to the accompanying drawings, which are made a part hereof, and in wl1ich- Figures l to 5, inclusive, are sections showing the cover at five successive stages, Fig. 5 showingit completed. Fig. 6 is a section of a cover embodying some features of the invention.

One object of the invention is to provide a cover which shall be stronger, more durable, and superior in other respects to covers as heretofore constructed; and another object of the invention is to provide a method by which the improved cover may be made with' the least possible waste of material and at a minimum cost; and to these ends the invention consists in the features of novelty that are particularly pointed out in the claims hereinafter.

The completed cover, as shown in Fig. 5, has a Haring portion A and a cylindrical portion B that are integral, a diaphragm C, l0= cated in the cylindrical portion, and having a marginal ange c,`bent to embrace a bead b on the interior of the cylindrical portion, and a handle D, the ends of which project beneath the bent margin c of the diaphragm.

The method of making this cover is as follows: The sheet-metal blank is drawn by dies to the form shown in Fig. l, where A represents the Haring portion, B the cylindrical portion, and C the diaphragm. The next step in the process is to sever the neck a short distance from the diaphragm, leaving aV portion of the cylindrical portion on the diaphragm to form the ange c, as shown in Fig. 2. Thediaphragm and its ange are then redrawn to reduce its external diameter sufficiently to allow it to be forced into the cylindrical portion, as shown in Fig. 3, this being the next stepin the process. The handle D is then put upon top ofthe diaphragm, With its ends touching or close to the ange,

SBIMNO. 533,606. (No model.)

and the fiange and cylinder are then subjected to the action of beading-rolls to form the bead b and at the same time bend the flange c over it.

If desired, the handle may be secured without conning its ends beneath the bead, as shown in Fig. 6.

l. A cover for milk cans havinga seamless flaring portion, a seamless cylindrical portion integral therewith, a bead on the interior of the cylindrical portion, a diaphragm closing the cylindrical portion and having a marginal ange embracing said bead, and a handle having ends projecting beneath the bent ange of the diaphragm, substantially as set forth.

2. The method of making covers for milk diaphragm from the cylindrical portion and then securing the diaphragm in the cylindrical portion, above the bottom thereof, substantially as set forth.

4. The method of making covers for milk cans which consists in drawing the blank to a form havinga flaring portion, a cylindrical portion and a diaphragm closing the cylindrical portion, severing the cylindrical portion some distance from the diaphragm, leaving said diaphragm with a marginal flange, redrawing the diaphragm to reduce its diameter to less than the interior diameter of the cylindrical portion, and securing the diaphragm in the cylindrical portion, substantially as set forth.

5. The method of making covers for milk cans, which consists in drawing the blank to a form having a flaring portion, a cylindrical IOO portion, and adiaphragm closing the cylindricylindrical portion and the flange of the diacal portion, severingr the cylindrical portion phragm to secure the diaphragm in place, 1o some distance from the diaphragm, leaving substantially as set forth.
