DANIEL B. WOOSTER, ()F MARSHFIELD, VERMONT.
MILK-COOLER.
SPECIFICATION forming part of Letters Patent No. 275,315, dated April 3, 1883.
Application filed February 24, 1883. (No model.)
To all whom it may concern:
Be it known that I, DANIEL B. Woos'ramof Marshfield, in the county of Washington and State of Vermont, have invented certain new and useful Improvements in Milk-Coolers; and I do hereby 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 pertains to make and use the same.
My invention relates to an improvement in apparatus for cooling milk.
1n the accompanying drawings, Figure 1 is a view in perspective of my improved milkcooler. Fig. 2 is a vertical section of the same. Fig. 3 represents a modification of the transparent eduction-tube. Fig.4isamodified form of cabinet, showing its adaptation for the reception of two or more milk-receptacles.
A represents a box or cabinet, preferably made of wood,and provided with a hinged lid, B, and a swinging or sliding door, 0. A partition, D, having a central perforation, E, is secured within the cabinet.
F represents an elongated milk-receptacle, the upper portion of which extends above partition 1), and the lower portion depends below the same.
G is a sheet-metal ice receptacle, the upper edges of which are secured to the upper edges of the cabinet, and its bottom His cut away to correspond to configuration of the milk-receptacle, which latter is attached theretoin a water-tight manner.
From the above it will be observed that a water-tight ice-receptacle is formed within the cabinet around the upper endonly of the milkreceptacle.
The top a of the milk-receptacle F extends slightly above the top of thebody of the cabinet or the upper edge of the ice-receptacle, so that should cold water be poured into the icereceptacle and the latter completely filled the water is prevented from entering the milk'rcceptacle F.
A cover, I, provided with a downwardlyprojecting flange, 1), is secured to the top of the milk-receptacle. The flange I) does not fit the periphery of the milk-receptacle snugly, an open space,c,between the same being formed. As the water rises in the ice-box it will form a liquid seal between the cover and the milk receptacle, and thus prevent any admission or escape of air between such parts of the apparatus.
To the top of cover 1 is secured a curb or M ring, K, having a perforated bottom, 01, and within said curb or ring is placed loosely a filling, e, of cotton or other porous material.
The hinged lid B is provided with perforations j, which register with the ventilatingring K. By means of this construction and arrangement of parts the air is allowed to enter through the porous packing andinto the milkreceptacle, the porous material serving to purify the air by filtering all germs of impurity therefrom before it comes in contact with the M is comparatively smallrelative to the size of the milk-receptacle, and enables all the milk to be drawn off without allowing the escape of the cream therewith.
Heretofore the lower ends of milk-coolers have been provided with transparent creamgages; but when such gages are attached tothe milk-receptacle itself it is found very difficult, if not impossible, to accurately separate the milk from the cream. By forminga transparent cream-gagein the small eduction-tube all the milk can be drawn off before the cream makes its appearance, and then the spigot is closed and the cream drawn off in a separate vessel.
In Fig. 1. the eduction-tube is represented as being provided with a section, 9, of glass, to allow the ready inspection of the cream. Instead of such construction, that illustrated in Fig. 3 may be employed inlieu thereof.
In Fig. 3, N is a glass tube, and 0 an openwork casing, one end of which is attached to the milk-receptacle, while the other end is provided with any suitable valve or spigot, P.
I have shown my invention in Fig. 1 as consisting of a single milk-receptacle; but the cabinet may be of any desired size, and any number of milk-receptacles placed therein, as shown in Fig. et,and therefore I would have it understood that I do not limit myself to any particular numberofmilk-receptacles that may be arranged within asuitably-constructed cabinet. Again, the milk-receptacle and cabinet may be of any desired form, either round, square, or rectangular, as my invention is not confined to any particular shape of apparatus.
When ice or cold water is placed in its receptacle around the upper end of the milk-receptacle, the milk in the upper portion of the vessel is reduced in temperature, and the cream contained therein is separated in whole or in part. The cold milk then descends, and its place is supplied by a current of warmer milk ascending from the lower end of the milk-receptacle. The cooling of the milk continues, and the cream is separated therefrom. This action of the milk is constant, there being a constant downward currentot' cold milk,wliich latter, when it reaches the top of the milk receptacle, is reduced in temperature and parts with its cream. This action of milk insures a speedy rising of the cream,as every particle of the contained milk is subjected to a continuous reduction of temperature.
The ice-box is provided, or may be provided, with suitable inlet and outlet pipes for running water, to insure a constant stream of pure cold waterin direct contact with the milk-receptacle.
1 make no broad claim in this patent to the cabinet in combination with the milk andice receptacles, as such restricted claims are embraced in my original application, filed January 17, 1879, of which this is a division application.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination of the cooler-tank, open at its top, with the can extending below the bottom of the tank, and having such extension provided with a discharge-outlet and transparent pane, substantially as set forth.
2. The combination of a cooler-tank and a milk-can extending below the bottom of the tank, terminating-in an outlet located at the front of the milk-can, near the lower end thereot",and provided with a stop-cock in said outlet.
3-. The combination,with a cooler-tank, open at its top, ofa milk-can provided with a discharge-outlet, having a valve or stop-cock and transparent cream gage, both being located near the lower end of the milk-can and outside the cooler-tank, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
