To all whom zit muy concern.-

Be it known that I, JOHN ADDISON MYERS, a citizen of the United States, residing at North English, in the county of Iowa and State of Iowa, have invented a new and useful Milk-Cooling Apparatus, o f which the following is a specification.

The invention relates to improvements in milk-cooling apparatus.

One object of the present invention is to improve the construction of apparatus for cooling milk, more especiallythat shown and described in Patent No. 508,146, granted to me November 7, 1893, and to obviate the necessity of pumping the water to secure the circulation thereof. A further object of the invention is to provide an apparatus of this character adapted to cause a circulation of water by a slight adjustment of the parts and to cause the water in leaving a tank to escape from the surface, so thatthe warmer or' surface water will be drawn foff iirst and the cooler water will remain.

The invention consists in the construction cistern being shownin section to illustrate the arrangement of thecooling-coils.

is a vertical sectional view of the refrigeratorcasing. Figs. 3 and et are enlarged detail sectional views villustrating the construction of l the flexible tube of the tank. Fig. 5 isa detail View of the coupling. view illustrating the arrangement of the float of the flexible tube.

Like numerals of reference designate oorresponding parts in all the figures of the drawings.

l and 2`designate vertically-movable tanks,

arranged within a refrigerator-casing 3 and connected at each end bya 'rope' or cable 4.. or other iexible connection centrally coiled around a shaft or windlass 5, which is provided with an exterior crank-handle 6, bymeans of which the shaft or windlass is ro The tanks tated to raise and lower the tanks.

are adapted to move alternately in opposite Fig. 2

6 is a detail directions, and they are connected, as hereinafter explained, by pipes or tubes, and when it is desired to produce a circulation of water the full tank is raised to the position illustrated in Fig. 2 of the accompanying drawings, whereby the water will be caused to ow through the pipes or tubes,hereinafter explained, from the upper tank to the lower one, which operationwill fill the lower tank with `cool water. The lcrank-handle is engaged by a removable pin or key 7; but any other suitable locking device may be employed for holding the windlass against movement in eitherdirection for looking either of the tanks in an elevated position. The perforations 8 for the reception of the pin or key 7 are formed in a bearing-plate 9, arranged at the front of the casing, as clearly illustrated in Fig. l of the accompanying drawings.

' The tanks are connected byexterior flexible tubes lO'iwith pipes Il, preferably constructed of metal and extending through the bottom of the casing and connected at their lower terminals lby a coil l2, which may be of any length andwhich is designed to be located in a well or cistern, as clearly illustrated in Fig. 1 ofthe accompanying drawings, so that Athe water in the coils will have its temperature reduced. The pipes ll may be arranged `in any suitable-manner to suit the location of the casing 3 relative to the well, cistern, or other means for cooling the coil. The flexible tubes l0 are connected with the inner sides ,0f the tanks at a point above the bottom, so ,that when the water is allowed to escape from the upper tank a predetermined quantity will remain therein, so that neither tank will ever be dry but the exible tubes may be connected at the bottoms of the tanks or at any other point, and it will be apparent that the circulation of water from one tank to the other reduces its temperature. and that the tanks are supplied the labor of pumping. The casing 3 may be constructedin any suitable manner and is designed to be provided with suitable doors, as shown,- `and -its capacity is such that it may be employed for cooling things other than milk. The milk is designed to be arranged within receptacles i3 of less depth IOO than the tanks and are designed to remain open and to iioat, so that the greater portions of the receptacles will remain submerged at all times, as illustrated in Fig. 2 of the accompanying drawings. The milk receptacles or cans 13 will be of a size corresponding to the distance of the upper ends of the tubes 10 from the bottoms of the tanks, and the desired depth of water within the tanks may be controlled by positioning the upper ends of the flexible exterior tubes 10. As the water begins lo flow into the bottom tank the receptacle 13 will rise and fioat, so that its position relative to the surface of the water remains unchanged.

In order to take off the surface water of the uppermost tank, so that the warm water will run ofi first and the cooler water remain longer in the tank, a flexible inner tube 14 is provided and is connected near one end with the outer or exterior tube 10 by an approximately T-shaped coupling 15, which extends through the inner wall of the tank, forming an exterior nipple, as clearly shown in Figs. 3 and eL. The interior flexible tube is provided near its lower end with an aperture 16, registering with the horizontal outwardly-extending portion of the T-shaped coupling, and the upper portion of the flexible tube is connected with a oat 17, which is adapted to support the upper end of the inner flexible tube 14 at the surface of the wat-er, so that the surface water will flow through the flexible tube. The oat may be construct-ed in any suitable manner, and it is preferably provided at its bottom with a depending arm 18, having an eye or ring 19, through which the fiexible tube is drawn and which permits the iiexible tube 14 to be readily adjusted, so that its upper end will be in proper position to receive the surface water.

The lower end of the inner exible tube extends beyond the T-shaped coupling and is provided with an outwardly-opening valve 20, which may be constructed in any suitable manner, but which preferably consists of a short highly-flexible tube having one end stretched over the lower end of the tube 14:. This short exible valve-tube is adapted to collapse around the lower end of the tube 14 and prevent water from flowing into the same at this point; but when water is fiowing into the tank the valve-tube will open automatically and permit such water to be delivered to the tank at the bottom thereof.

It will be seen that the milk-cooling apparatus is exceedingly simple and inexpensive in construction and that a circulation of Water may be eected by altering the position of the tanks with relation to each other and changing the full tank froln the bottom to the top. Also it will be clear that all pumping is obviated and the quantity of water within the well or cistern is not diminished. It will also be apparent that the position of the milk-receptacles relative to the surface of the water within the tanks is unaffected by the change in the position of the tanks. Furthermore, it will be clear that if the connection between the flexible exterior tube 10 and the tanks is made at the bottom of the latter the upper tank will be completely emptied, and I desire it to be understood that various changes in the form, proportion, size, and the minordetails of construction within the scope of the appended claims may be resorted to without departing from the spirit orsacrifieing any of the advantages of this invention.
