MILK-COOLER.

SPEGIFIGATION- forming part of Letters Patent No. 290,519, dated December18, 1883.

Application filed May 11, 1883. (No model.)

To all whom it may concern.-

Be it known that I, ISAAC S. BRANDEN- BURG, of Peoria, Peoria county, Illinois, have invented a new and Improved Milk-Cooler, of which the following is a full, clear, and exact description. I

My inventionrelates to improvements in milk-coolers; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of my improved cream'raiser, the section being taken on the line y Fig. 2. Fig. 2 is a sectional elevation taken on the line a: m, Fig. 1; and Fig. 3 is a perspective view of one of the cream-cans in which the cream is to be raised.

I place two or more cans, a, in a tank, 1), side by side, and cover each row of cans with a troughshaped cover, 0, inverted and placed on the handles e of the cans for support, which handles are located sufficiently below the upper ends of the cans for closing thecans by a water seal when the tank is filled with water to about the height of the cans, and the said handles are also placed suificiently low to allow the water to rise under said covers and compress the air therein to cause presscates with the open air, and the lower passage, 0, is below the water-line of the tank. By this construction the ends of the cover are materially strengthened around the seal, so that the metal after constant use will not be liable to bend or twist, as is the case when a straight flange is employed. The function, therefore, of the construction of the end convex chambers with double walls is to protect the seal by rendering the ends stronger, so that they will not be so liable to bend and twist as they would be if a single straight flange, as ordinarily employed, were used. With a long cover,

such as I employ, I find straight end flanges uncertain, as they are liable to become bent or broken in use when not protected by the convex flange or very carefully handled. In removing a cover from the cans the confined air under the cover is allowed to escape into the open air through the passages 0 it before the lower edge of the cover is raised above the water-line, thereby permitting the cover to be more easily removed than if a single straight flange were employed. The covers are seen red by barsf, placed on the covers and under the brackets 9, attached to the inside of the tank to prevent the covers from being lifted by the water and air pressure under them. The tank is provided with an overflow-pipe, j, which maintains the water at the proper level in' the tank.

It will be seen that any vapor rising from the cans, also from the water, will condense on the covers and flow down the sides into the water of the tank, and thus will be prevented from dripping back into the cans and injuring the quality of the cream, and time will be economized in the raising of the cream.

The overfow-pipe may be pulled out of its hole in the bottom of the water-tank to allow the water to flow out of the tank when desired.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- The combination of cans cahaving handles e arranged below their tops, inverted semi-cylindrical-shaped covers 0, having end chambers, h, provided with passages on 0, said covers being larger than the tops of the cansand placed over them on said handles, holdingbars f, and water-tank b, substantially as shown and described.
