GEORGE D. JOHNSON, OF LA GRANGE, OHIO.
MILK-COOLER.
SPECIFICATION forming part of Letters Patent No. 443,854, dated. December 30, 1890.
Application filed May 7, 1890. Serial No. 350,904. (No model.)
To all whom it may concern.-
Be it known that I, GEORGE D. JoHNsoN, a citizen of the United States, residing at La Grange, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Milk-Coolers; and I do declare the following to be 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, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to milk-coolers, and particularly to the class of aeration for purifying and cleansingmilk.
The invention consists in the novel arrangement and construction of parts, as will view of the top portion of the plunger, valve,
and valve-stem.
Like letters denote like parts throughout the several figures.
The cooler or cleanser A is made cylindrical in form and of tin or any suitable material.
The cooler is open at its bottom B and closed at its top 0, except for a valve D, located in the center of the top, which valve may or may not be used in operating the cooler. The top 0 is preferably of convex form, and is suitably attached to the cooler A by soldering or riveting, or it may be made in one piece with the cooler, as shown in the drawings.
Near the joint of the cooler A and its top 0 is a series of small holes or perforations E, made through the cooler for the purpose of the escape of air as the cooler descends into a pail or can of milk.
The valve D is constructed so as to close as the plunger descends into the milk and open when the plunger is withdrawn from the milk. The said valve D is provided with the ends of a handle H.
a valve stem F, which projects downward through the enlarged portion G of the keeper g, which extends across the top 0 of the plunger on the inside, and which may be formed in the same piece with the top 0, or it may be riveted or otherwise secured in position, so as to be separate from the said plunger. According to the construction of the valve shown and described the pressure of the air from within as the cooler is plunged into the milk closes the valve, and when the plunger is withdrawn the suction of air from within opens the valve.
To the sides of the cooler A are attached This handle may be of any desired form or length; but I prefer to construct it as shown in the drawings.
The operation of my device is as follows without the use of the valve: The coolerA is plunged into a can of milk down to the bottom thereof. The valve D is immediately closed. The air is forced upward and bubbles up through the milk and out the perforations E, this purifying and cooling the milk by relieving it of all its animal or otherheat.
It will be observed that my cooler can be readily washed and cleaned without removing any of its parts, as the bottom is entirely open. This facility for cleaning is an important one in my invention, as such devices have to be washed and cleaned every day.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a milk-cooler, the combination, with the cylindrical body having a series of apertures near its top and an open bottom, of the handle H, having its ends secured to the said body and extending upward to form a loop, the convex top provided with a valve having a stem, and the keeper g, having the enlarged portion G, which forms the valve-stem guide, said valve adapted to close as the plunger descends into the milk, substantially as shown and described, and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
GEORGE D. JOHNSON.
