JACKET-CAN.

SPECIFICATION forming part of Letters Patent No. 574,987, dated January 12, 1897.

Application filed April 6, 1896. Serial No. 586,437. (No model.)

T0 at whom it may concern.-

Be it known that I, DANIEL FARRELL, J r., residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain I useful Improvements in Jacket-Cans; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention has relation to a new and novel jacket-can.

The object of my invention is primarily to provide a jacket-can in which there shall be no double-seaming, and which shall, further, be provided with a double offset at the upper and lower edges, so as to provide a solid double rim, upon which the can is made to rest, and a rim of less diameter, offering a seating for the bottom or breast of the can.

The invention further embraces a method by means of which these latter offsetting shows a central sectional View of a'can em-' bodying my invention, while Fig. 2 shows a top view of the body-blank before it is curved.

My invention comprises, essentially, two metal blanks marked, respectively, 3 and 9, the former being an elongated blank having an upper and lower integral extending portion t 5 and 6 7, which extends a short distance beyond the ends 3 of the blank 3. The blank 9 comprises a disk which is provided with a wooden disk forming the jacket-bottom, the edges 10 of the disk 9 being crimped over to form a holder for this jacket-disk 12.

In the manufacture of cans and other small tin receptacles a slight saving of material or tin is of greatimportance, as the finished article itself can be sold but for a small amount. In my present invention I effect a saving which, while intrinsically small, is of great importance in the manufacture of this can, as commercially a can manufactured according to my invention can be made cheaper than cans of like grade and capacity and made ac cording to the old method.

The blank 3 at its top edge l 5 and the bottom edge 6 7 is turned over upon the blank, approximately in the form of the letter V, so that the wooden jacket 8, which is nothing more or less than a rectangular blank of wood veneer or other suitable material, is of a size so that it can be readily pushed through these V-shaped edges and be held thereby. The next step is to lap over the edges 3 of the blank 3 and place these ends 3' below the V-sha-ped top and bottom edges. The blank is then carried to the forming-rolls, by means of which the V-shaped edges are compressed approximately into the letter Y, the upper extending stems curving slightly by virtue of the jacket being within the blank while the same was formed, as is shown in Fig. 1. So far we would have but a flat blank having the Y-shaped top and bottom edges, within which the flat veneer is held. The blank is next given a circular form by means of suitable rolls which curve this blank in two diameters, the smaller one forming a seating for the bottom, the larger forming the doubleedged rims, the metal blank being pressed into a cylinder while acting as a holder and containing the jacket. Any suitable depth of the top and bottom edges may be obtained simply by extending the portions 4 and 7. The open cylinder is next united by means of solderingthe edges 3, forming a seam 13, which is visible and is made upon the outside. The bottom-blank 9, which has been made of a proper size, is next dropped into one of the open cylindrical ends, where it finds a snug and solid rest against one of the curved stems of the Y-shaped ends, where the bottom is securelysoldered. The can is ready to be used in this form, or, if desired, a flat or conical breast may be provided, as is shown in Fig; 1.

The invention is noticeable because of its simplicity; and,

Having thus described my said invention, what I claim. as new, and desire to secure by United States Letters Patent, is-

l. As a new article of manufacture, a jacketed sheet-metal body'blank, said blank being provided with a top and bottom returned edge in the form of the letter Y facing one another, the main stem of the letter being of a double thickness and forming the extreme edges of the blank, the wings being adapted to form a groove, in combination with a jacket inovably held within said top and bottom groove.

2. As anew article of manufacture, a jack-' eted sheet-metal body-blank, said blank being provided with a top and bottom returned DANIEL FARRELL, J R.
