IMPROVED MILK-CAN.

Specification forming part of Letters Patent No. 37,977, dated March .24, 1863.

To all whom it may concern.-

After constructing the cylindrical body of Be it known that we, HENRY PRESTON and I the can A we take tiirplate, which is at least JAMES hIAHOOD, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Milk-Cans; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a central vertical section of a milkcan having our improvement applied thereto; and Fig. 2, a horizontal section of the same through the middle of one of its bands, like letters indicating the same parts when in hot-h figures.

Our improvement relates to the banding of milk-cans; and thisis a very important part of their construction, because they are generally snbject-ed to very rough and hasty treat,- ment in transporting, especially at the rail road-depots. Each of the bands of these vessels has heretofore been constructed of two or more pieces of common tin-plate, either wired along its two side edges or lapped over a stiffening band of sheet-iron, and then secured around the vessel by simply soldering its ends together and its top and bottom edges to the sides of the can. Consequently there is not a union between the broad inner sides of the ilon bands and the vessel, nor between the tin bands and either the wire or the sheet-iron stiffening; and the consequence is that there is not only a want of proper solidity and strength, but that the tin-plate covering of each soon becomes worn through to the iron stiffening, producing ragged edges in the former, and also admitting water to the interior of the band, which soon oxidizes the iron stiffening and renders an entire renewal of the whole band necessary in order to preserve the can in use. To obviate these objections is the object of our invention.

lt consists in constructing each of the bands of a milk-can in a solid single piece of thick tiirplate, and securing the whole of its inner surface in perfectly solid union with the surface of the tin-plate of the vessel, its two ends abutting together and being each additionally secured to the said vessel by means of a rivet through the band and side of the vessel, as hereinafter described and specified.

In the drawings, A is the can; a a, the hands, and a a the rivets.

one-sixteenth of an inch thick, and out there from bandstrips of the usual widths and of t such lengths as will cause the ends of each to i abut accurately together when the strip is bent and fitted accurately and closely around the outside of the vessel, as indicated in Fig. 2. \\e now punch a rivet-hole through each end of the said strips, and also corresponding holes through the one side of the vessel A, and by means of the rivets a secure them in their proper relative positions as bands around the same, as indicated in the drawings, and finally solder them solidly to the said vessels, an operation which is easily accomplished, because the inner surface ot each of the said bands, like the body of the vessel A, being coated with tin, the solder runs freely between them and causes a perfectly solid union.

In order to prevent any accumulation of dirtor grease around the rivet-heads a, especially in the inside of the can, we cover them with solder so as to produce a smooth and nearly even surface thereat; and as the usual support or flange at the bottom of the vessel is always made of thick untinned sheet-iron, the band a around it is soldered only at its upper portion, the additional rivets a. a passing through it and the said flange and holding it firmly thereto, as seen in Fig. 1.

The saving of labor in the construction and application of our said hands over those of the old kind is very considerable, and the difference in the cost of material but trifling, if

any, while the superiority of the former for HENRY rR-EsroN. JAMES MAHOOD.
