DURNANT BURNETT, OF BEDFORD STATION, ASSIGNOR TO H. W. SHEPARD AND ROBERT SEAMAN, OF NEW YORK CITY, N. Y.

IMPROVEMENT IN MILK-CANS.

Specification forming part of Letters Patent No. 121,154, dated November 21, 1871.

To all whom it may concern: I

Be it known that I, DURNANT BURNETT, of Bedford Station, in the county of Westchester and State of New York, have invented a new and Improved Milk-Gan; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which Figure 1 is a vertical sectional view of the breast detached from the cylinder. Fig. 2 is a vertical sectional view of the can with the breast attached.

Similar letters of reference indicate corresponding parts.

The nature of my invention consists in form ing a seamless breast for a milk-can, and one in which the collar, arched top, and a broad cylindrical hoop are all formed together out of a single piece of metal.

The great practical advantage of my invention will readily suggest itself to all familiar with that branch of the mechanical art to which it relates. In attaching a breast of this style and form to the cylinder the independent outer hoop now invariably used to protect the seam-joint formed by the union of the breast and cylinder is dispensed with, as is also. the seam-joint itself; and, besides, a can having this style of breast is much stronger, and consequently better enabled to resist the rough handling to which this class of cans is necessarily subjected in being passed to and fro over railroads, &c. As the cylinder is inserted in the breast, the upper edge of the same butting against or meeting the breast at the base of its arch, it will readily be seen how impossibleit is for any pressure on the breast to effect the union between the same and the cylinder, unless said pressure should be sufficient to crush in the cylinder.

To enable others skilled in the-art to make and use my invention, I will now proceed to describe its construction and operation.

A is the cylinder and B the bottom, and each may be constructed in the usual or in any other suitable manner. 0 is the arched top plate. D is a brdad cylindrical hoop, and O is the neckflange or collar. Thesethree-the collar 0, arched top plate 0, and hoop D-are all cast in one piece, so as to form a seamless bnMcan be attached to the cylinder without employing the independent outer hoop now invariably used to strengthen the joint between the breast and the cylinder. By using this breast, dispensing, as it does, with all necessity for this hoop, one step in the process of manufacturing the can is saved, and a most important one, as the attaching of this hoop is not only exceedingly troublesome, but expensive. By reference to Fig. 1 it will be seen that the breast is seated on or over the cylinder A and then the two are riveted and soldered together, the broad cylindrical hoop D encircling or inclosing its entire upper section, and the base 0 of the arch resting on its upper face or raw edge a. The great advantages of this arrangement, and which are due entirely to the style and form of the breast, are, beside avoiding the use of the independent hoop and the labor of securing the same, it also dispenses with all necessity for a seamjoint on the inner surface of the can, and which, as is well known to all dairymen, it is almost'impossible to keep clean. The can, when thus constructed, is also much stronger, as all danger of its leaking at the point of union between the breast and eylinder-and this is where the leak generally occurs-is securely guarded against, as no pressure on the breast, and which in the transportation of the cans is frequently great, can ever start the broad bearing or connection that unites the breast and cylinder, unless the same is sufliciently great to crush in the cylinder. E is the neck of the can, and is inserted and secured in the collar or flange O in the usual manner 5 or when the breastzis cast it may be formed in one continuous piece with the collar.

Having thus fully described my inventio what I claim therein as new, and desire to secure by Letters Patent ofthe United States, 1s

As a new article of manufacture, the arched plate 0, outside collar 0, and cylindrical hoop D encircling the cylinder, all so formed together out of a single piece of metal as to produce a seamless breast for milk-cans, substantially as described.
