IMPROVEMENT IN MILK-CANS.

Specification forming part of "Letters Patent No.

32,439, dated May 28, 1561; reissue No. 4,781, dated March 5 1872. T

To all whom it may concern."

Be it'known that PHILIP Tears, of the city of New York, in the State of New York, heretofore invented certain new and useful Iniproveinents in Milk-Cans; and that the following is a full, clear, and exact description of the same, reference being had to the drawing which accompanies and forms part of this specification. c

.The breastportion and bowl, as well as the covers, of milk-cans have heretofore beenmade each of a number of pieces of metal soldered together, thereby making a great number of joints or seams in the construction of each of these parts, aside from the joints made in connecting these parts together to produce the can. This mode of construction rendered the cans quite difiicult to thoroughly cleanse day by day, which it is necessary to do, else the milk lodging in any joint will sour and infect the whole of the milk when the can is refilled; and joints, the more injury the can receives from the rough usage to which it is subjected in its transportation back and forth by railroad. It is, therefore, desirable to construct the several parts of a milk'can with the least possible number of seams or joints, and thereby cheapen the cost of manufacture, and render the cans stronger and more durable.

This invention consists in a seamless breast for a milk-can, made of asingle piece or sheet of metal by stamping it up in the desired shape by suitable dies, and adapted to be properly secured to the body of the milk-can; it

. also consists in a bowl and cover for a milkcan, of similar construction it also consists in the combination, with the body of a milkcan, of a seamless breast, and bowl, and cover, either or all, in a single can it further consists in the method of connecting the breast with the body of the can by means of a do ubleseain joint covered by a hoop, whereby a'firnl water-tight union of the two parts is efl'ectcd; it further consists in the new article of manufacture of a milk-can, which, as a whole, is of a new and improved construction.

In the accompanying drawing, Figure 1 is a side elevation of a milk-can embodying in its construction these several improvements.

, moreover, the greater the number of the I ment permits the hooped Fig. 2 is a vertical longitudinal central section of the same. A designates the body of the can; B, the breast (J, the bowl; and D, the cover, all of which parts are, in the case of the larger sizes of cans, preferably, composed of thick tinned iron-a kind usually made expressly for use in the manufacture of large milk-cans. The body A of the can is made in the usual or any suitable manner, and provided with a bottom, K, and strengthing-hoops F G, as usual. The breast B is made of a single piece, preferably a circular piece, of sheet metal, stamped by suitable dies into the required shape, as will be clearly understood by reference to the drawing, where it will be seen that the said breast is provided with an upwardly-projecting portion or flange at its top, which flange is thrown up at a greater or less angle to the main portion of the said breast, and which is adapted to receive and have properly secured to it the neck or bowl of the can. The bowl 0 is also formed of a piece of sheet metal by submitting the same to the action of stamping-dies of the proper shape to give the flaring form to the ends of the bowl. The upper edge of the bowl is preferably wired, strengthening and giving a finished appearance to the mouth of the can. To unite the bowl to the breast, the lower end of the bowl is introduced for a suitable distance into the upper end of the breast B, and the two soldered together. The overlapping edges a a are then filed down so as to present a smooth surface at this joint inside and outside of the can, to facilitate the cleansing of the same. It will therefore be perceived that this improve neck hitherto em ployed between the bowl and breast to be entirely dispensed with, and thereby avery con siderable saving is effected in the manufacture of n1ilkcans, besides uniting the breast and In uniting the breast with the body it is desirable to provide the lower end of the breast with a wide flange, and the upper end of the body A, also, with a flange, the two flanges being brought together, so that the one rests upon the other;

they are then turned over so as to form what is called a double-seam joint, and this joint is or bent over a wire, for

pressed against the body A of the can, as will By thus providing a seamless breast and be understood by reference to Fig. 2. It will bowl and cover for a milk-can, a great decrease be noticed, by reference to Fig. 2, that, when in the cost of manufacture of milk-cans is efthe breast and body are thus connected tofected, besides the production of a much betgether, the flange upon the breast becomes a ter and more desirable and durable article, downwardly-projecting rim, b,which laps upon and one-which can be thoroughly and easily the body A.
