MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 273,764, dated March 13, 1883.

Application tiled November 15, 1882.

To all whom it may concern:

Beit known that I, MILTON O. ROBERTS, of' Worcester, in the county of Montgomery and State of Pennsilvania, have invented an Improvement in Milk-Coolers, ot' which the following is a specitcation.

My invention has reference to milk-coolers; and it consists in certain improvements in means to cause a circulation of the cooling- Water, and in the construction ot' the milkcooler as an entirety, all of which is fully set forth in the following' specification and shown in the accompanyingdrawings,which form part thereof.

In the drawings, Figure l is a perspeciive View of my improved milk-cooler. Fig. 2 is a sectional elevation of same on line m. Fig. 3 is a sectional plan of same on line y y. Fig. 4 is a crosssection ot' same on line z z,- and Fig. 5 is a plan view, showing a moditied arrangement of the means to guide the circulation of the water.

A is the water-tank. B is a frame supported upon the upper rim or edge ot' the water tank, and carries the tanks or milk-vats O O O, of which I prefer three, the said tanks or vats being connected together at the bottoms by tubular connections D D, to allow the milk and cream to circulate from one vat to another. These vats hang clear ofthe bottom and sides and leave spaces between themselves for the circulation of water. Divisions G Gr' cause the Water to circulate in a sinuous curve, passing along one side ot' one ot' the outer vats, then back between the other side and the adjacent vat, and so on, the cold water starting from a chamber, L, and being received in a chamber, K, these chambers L and K being separated from each other by a division, F, in which is arranged a rotating feed-wheel, ar-

ranged, like a screw-propeller, with many blades, the said feed-wheel H being rotated by a shaft, I, and pulley J, or other equivalent means. The compartment or chamber K may act as the icebox. Fresh water may be admitted by a pipe, O', and the waste may run oft' by a waste-pipe, O. The chamber L is closed by a case or cover, L', having` an apperture, m, on one side and close to the top, which opens into a trough, M, provided with spoutsm',arrangedoverthe vats O,and adapted (No model.)

to pass feed-water into pans N, supported above said vats and forming cooling-covers to saine. The water in'coinpartinent L is caused to rise above the level of that in compartment K by creating a great suction through the agency ofthe wheel H, the water being more rapidly drawn in than it can escape through the passages around the tank. The pans N are preferably provided with tubular vents n, to allow escape of the odors and vapors arising from the milk-vat. The cold water runs off from these pans, by spouts n', into 'a trough, N', and is conducted back into the tank A by pipe N2. l do not confine myself' to the exact construction ot' these troughs'` as the water may be conveyed back to the tank by a pipe or aperture direct from the pans, and water may be i'ed into the pans by pipes direct l'rom chamber K or from main O', it' so desired.

R is a wooden cover to cover the pans and vats, and is preferably hinged to frame B.

E is the tap to draw oi' the milk and cream.

In place of causing the cold water to pass first on one side ol thc milk-vat and then on the other, coming into contact with only one side at a time, I may dispense with the divisions G G' and bring the division F up against the middle vat, C, as shown in Fig. 5, and then the circulation will be caused to take place in such a manner as to pass down both sides ot' one ofthe outer vats and one side ofthe middle. vat, and then return in the opposite direction, but in contact with the remaining side ot' the middle vat and other outer vat. This is clearly shown.

The divisions G and G' (and F in the case of Fig. 5) may extend along' the bottom ofthe tank to insure more perfect circulation, and also act as a support tor the vats C; or, if desired, the bottom ofthe milk-vate may be provided with ribs to perform the same function.

The circulating propeller-wheel is shown in another pending application of mine, but is claimed in another construction of milk-cooler.

Having now described lny invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a milk-cooler, the combination of a water-tank, a milk-vat, a rotating circulatingwheel, and means for directing the water-'currents, so that the water shall be continually changing its position, and thereby cool the milk in the milk-vat, substantially as and for the purpose specified.

2. In a milk-cooler, the combination of a watertank, a milk-vat, an ice box or compartment,'a rotating Water-circulating Wheel,l

ranged over said milk-vats, means t0 cause the' Water from the closed chamber to How into said pans, and means to cause the water from said closed chamber to circulate around said milkvats and back into the icebox or open chamber, substantially as and for the purpose speced.

4. In a milkcooler, the combination of watertank A, milk-pans U, connected by tubesD,

chambers K and L, divisions F, G, and G', cir-` y culating-wheelH, shaft I, and pulley J, or its equivalent, substantially as and for the purpose yspecited.

5. In a milk-cooler, thecombination of Watertank A, milkpans C, connected together by tubes D, chamber K, closed chamber L, partition F, circulating-Wheel H, shaft I, pans N, having vent-tubes n, means to conduct Water from chamber L to said pans, and means to conduct the Waste-,water back into the tank from said pans, substantially as and for the purpose specified.

6. The Vcombination of Watertank A, milkvats C, chambers K and L, divisions F. G, and G', circulating-wheel H, shaft I, pans N, having vents n, means to conduct Water to and from pans, and cover R, substantially as and for the purpose specified.

In testimony of which invention I hereunto set my hand.

MILTON O. ROBERTS.
