CREAMERY.

SPECIFICATION forming part of Letters Patent No. 338,577, dated March 23, 1886.

Application filed June 29, 1885:

To all whom it may concern:

Be it known that I, NATHAN YINGST, a citizen of the United States, residing at Reistville, in the county of Lebanon and State of Pennsylvania, have invented a new and useful Inr provement in Oreamers, of which the following is a description.

This invention is an improvement in creamers, and has for an object to provide a simple construction by which the milk may be thoroughly and quickly cooled and the heat therefrom be carried directly out of the casing or cabinet, each and all of said parts being especially formed with a view to conveniently and expeditiously cleansing the same.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a front view of my improved creamer. Fig. 2 is a top view with the cover and Ventilator-pan removed. Figs. 3 and 4 are partial transverse vertical sections of the creamer on, respectively, lines 00 w and y y, Fig. 2.

The cabinet is formed with an upper compartment, A, and a lower compartment, A. In the front wall of the upper compartment is provided a window, a, and the lower compartment has a door, a, by which access may be had thereto for the purpose of inserting and removing the cans or pans which it is desired to fill from the creaming-pan. A pipe, B, leads through the division A between the compartments A and A, and is provided within the compartment A with a stop-cock by which it may be openedv or closed at will. This pipe B extends into the compartment A and is detachably connected with the cream ing-pan through the bottom thereof, as will be understood from Fig. 4. The creamingpan 0 is in practice placed within the compartment A, and preferably has legs 0, by which it is held clear of the floor thereof in order to permit the circulation of water below such pan. Within the pan is secured or formed the hollow globular cooler D, usually located centrally of the pan, as shown. This cooler has its upper side arranged sufficiently below the top of the pan to prevent it projecting above the contents and limiting the creamforming surface, and its lower end is connected Serial No. 170,192. (No model.)

with the bottom of the can,and opens outthereof at d, as shown. It is usual and preferable to form this connection by means of the rounded neck D. This cooler is made globular for several reasons. In the first place the continuously'and evenly curved interior of the cooler facilitates the formation of currents in the water discharged into such cooler and effects a distribution of such water evenly and generally on the interior of the cooler. Again, this globular form of the cooler obviates all corners and angles on the surface of the cooler within the pan, and thus enables the convenient and rapid washing of the pan, which manifestly is of importance in the class of devices to which my invention relates. This form of cooler also, by flaring outwardly from its juncture with the bottom of the can, extends laterally into the body of milk and exposes a larger cooling-surface with the least possible reduction of the milk-containing capacity of the pan. It is preferred to provide an air-discharge tube, E, which connects at one end with the cooler and extends laterally thence through the side of the pan. This lateral instead ofvertical arrangement of the pipe is employed because it avoids any break in the cream-forming surface at the top of the pan.

In the front end of the pan is formed a sightwindow, 0 which registers with the window a in the cabinet, and thus enables the condition of the contents of the pan to be ascertained without raising the covers. The dischargepipe B connects detachably with the bottom of the pan, as will be understood from Fig. 4. The ventilator-pan F is placed upon the creaming-pan and has an upwardly-extended tube or fiue,f, which projects through an opening, F, in the cover of the cabinet. This opening F is made larger than the tubef. By this construction the heat from the milk is conveyed directly off and out of the cabinet, and the air heated within the cabinet is also passed directly out without the possibility of its contaminating or otherwise influencing the contents of the creaming-pan. The water-inlet pipe G enters through one side of the cabinet, near its top, and is disposed, preferably, wit-h its extremity extended within and terminating close to the top of the cooler, so that the water entering will be discharged directly against the interior crown of the cooler and be spread thence over the inner side of the cooler, operating to cool the contents of the pan, as will be seen. The exit-pipe H is located on the opposite side of the cabinetfrom pipeG and slightly below the plane thereof. There is also provided a pipe, I, having valve 6, by which the upper compartment may be emptied;

In operation, when the cream has properly formed, as may be ascertained by sight through the window before described, the cock b may be opened and the milk may be drawn off and the cream left. The cream will fall onto the globular cooler, and may be easily and thoroughly removed therefrom. It will also be noticed that the globular form of the cooler facilitates the formation of currents in the body of milk by dispensing with all angles likely to break such currents. These currents, as is well known, are produced by the cooling and descending of the portions of milk adjacent the cooler and the replacing of such portions by warmer milk.

Heretofore creaming-pans have been provided with coolers opening out of their bottoms and having vertical sides. I do not broadly claim such construction, as my cooler is dif-l ferent from and gives better results than such straight sided coolers. As described, my cooler has curved sides. A material advantage in this construction is that by it the currents of milk converging from all sides against the cooler will be deflected downward by the curved sides thereof and will be cooled in de scent, and when the bottom ofthe pan is reached will pass outward and upward. Thus the currents of the milk arepositive, move steadily,

and a constant circulation is had. In the case of the coolers having straight sides, the milk converging toward and against the same is stopped when it reaches the cooler and will not descend until it has been cooled by contact therewith. Thus the circulation is retarded and delayed, while in the case of my cooler it is constant, continuous, and the milk is rapidly cooled.

What I claim as new is The creamer substantially as herein described and shown, consisting of the cabinet having an upper compartment, A, a lower compartment, A, asight-opening, a, and alid or cover having an opening, 1?, the pan 0, located in compartment A, having a sight-opening, 0, and provided with a globular cooler, D, having curved sides and a vent, E, the water-inlet pipe G, extended through the side of the cabinet and having its discharge end extended into and terminating close to he crown of the globular cooler, the overfl -pipe H, the discharge-pipe I, the milk-drawing pipe B, passed through the partition between compartments A A, having its upper end detachably connected with the cooling-pan within the compartment A, and its other end extended into the compartmentAand provided with a cock, as b, and a cover, F, fitted over the pan, and having a tube, f, extended through the opening F in the top or lid, substantially as set forth.
