COMBINED CKREAMER AND R'EFRIGERATOR.

Application iiled September 21, 1881. Serial No. 42.354.

To @ZZ whom it may concern:

Be it known that I, FREDRIOI; W. Mesn- LnY, a citizen of the United States, residing at Poultney, in the county of Rutland and State of Vermont, havev invented certain new and useful Improvements in Dairy Creamery and Refrigerator Combined, of which the following is a specification.

My invention consists in certain improve ments upon the apparatus patented to me August 19, 1879, under Letters Patent No. 218,7 65, which said Letters Patent were `Asurgendcred and reissued April 13, 1880, No.

The object of my invent-ion is to provide a cream-raising apparatus and a refrigerator both united in a single structure, the reduced temperature in the refrigerator when closed being derived from the milk-setting and creamseparating apparatus with which the refrigerator is combined.

My invention therefore consists in a creamraising apparatus inclosed within and whollysurrounded by a cabinet-casing or equivalent structure, whereby undue convection of heat from the surrounding atmosphere isavoided, space being aiitorded within said cabinet for the storage of substances which require 'low temperature for their preservation, said stor-v age-chamber being cooled by the water chamber or chambers which depend from the icereceptacle of the milk -setting apparatus, whereby the reduction of temperature in the latter is utilized for the production of a .low temperature in the said storage-chamber-f My invention also consists in the combination, with the cabinet-casing, Of an ice cham-v ber or receptacle occupying the upper portion of the same, and a series of alternating waterchambers depending from said ice-receptacle, and adapted, together therewith, to receive thev milk -vessels, whereby the illuminated discharge-tubes leading from said vesselsv to the exterior are brought within the sight and reach of the operator from one side of the cabinet only.

My invention also consists in other matter specified in the claims.

Referring tov the drawings forming part of this specification, Figure 1 is a perspective, Fig. 2 is a plan of Fig. 1, the cover being re- JlClEE/@ATION forming part of Letters Patent No. 330,845, dated November 17, 1885.

moved, Fig. 3 is a front elevation, and Fig. t is a centralv vertical section, of an apparatus embodying, my invention.

As 1 have before stated, this invention consists in .certain improvements upon the apparatus described and claimed in Reissued Letters Patent No. 9,156, dated April 13, 1880. This apparatus embodied in substance the Ycold deep setting77 or Swedish method of 'raising cream ifrom milk, which consists in reducing the temperature of the latter to about 45 Fahrenheit, or even to 400, whereby the separation of the cream is greatly accelerated.

My invention,A as set forth in said Reissued Letters Patent, consisted in an improved apparatus for subjecting milk tothe necessary reduction of temperature, by which I secure a large degree of economy intime and an important saving of refrigerating material.

My said invention also consisted in an iinproved apparatus for separating the milk from the risen cream, whereby perfect separation is accomplished without removing the milkvessels from the cooling-chamber, the entire process of raising the cream and separating it from the milk being accomplished in the shortest possible time with the least possible expenditure of material, and in the most simple and effective manner.

The apparatus shown and described in my said Reissued Letters Patent forms no part of my present invention, except in those combinations of parts into which it enters as an element.

A in the drawings indicates a cabinet or ,casing made of wood and of any suitable size or shape` according to the number and arrangement of the milk-vessels which form part of the apparatus and are arranged with-l in said cabinet. The casing A opens at the top by means of a lid, B, hinged to one 0i the sides, as shown at Fig. 1, or it may be made in two parts, `each hinged to one end, as shown in Fig. 3. Doors also are provided for giving access to the lower portion of the cabinet, andA they may be placed upon Vone or both sides thereof, according of the milk-vessels within said cabinet, as will be more fully described hereinafter.

The cabinet A may bey made of any size to contain any number of milk-vessels, from a to the arrangement IOO placed in single can, as shown -in Fig. 4, up to sixteen, or even more, if desired, the construction being substantially the same in each. Within the cabinetA is placed a horizontal partition, C, (see Fig. 4,) situated at such a point as to leave not far from -three-fourths of the whole interior space below said partition. The metal lining D, for which galvanized iron is to be preferred, covers the inn-er surface of the walls of the cabinet above the partition C, a deadair space being left,if desired, between the walls and said lining. This same lining also covers and rests upon the partition C. One or more circular openings, according to the number of milk-vessels the cabinet is to contain, are formed in the partition and in the lining D, which rests upon it, and the cylinder E, formed of the same metal,and having a diameter equal to the opening in the lining D, is inserted from below until the edge of its open end is in contact with the edgeof the opening in the lining D, when the two are carefully soldered together so as to make a watertight joint. The lower end of the cylinder E is closed, and its depth is very little greater than the depth of the metal-lined chamber above the partition. It will be seen that each cylinder forms a contracted continuation of said upper chamber, which depends or projects through the partition C down into the lower portion of the space inclosed by the cabinet-casing.

F isa milk-vessel or can,of cylindrical form, having a diameter a little less than the diameter of the cylinder E, and a depth a trifle less than that of the said cylinder and the large upper chamber united. These proportions being substantially observed, it is evident that when any one of the said cylinders the can will stand partly therein and partly in thelarge chamber above, the walls of the cylinder E closely approaching the lower portion of the can F. In this position the can is supported by brackets a,soldered to its bottom and resting upon the closed end of the cylinder E. It is detachably secured in place Vby means of two perforated lugs,b b, on its side, which en-V gage by means of a pin, c, with a perforated strip, d, projecting from the wall of the surrounding chamber.

The bottom of the milk-can is of the construction shown in Fig. 4. It consists of the usual concave bottom, with an inclined false bottom placed above it,as shown at e, and inclined in such a manner that the lowest part is brought near one side of the can instead of at its central point. A discharge-opening is formed at said point, by which the contents of the can may be drawn off through the pipe G, having a suitable cock or shut-off. Thispipe, which is also shown in Fig. 4, is made of metal with a female thread cut in one end to receive the threaded end of-a nipple.which is fastened on the can and which projects downward through an opening in the bottom of the cylinder E. Tight joints are formed by placing rubber packing-rings inside and outside,

an additional ring and nut, ff', being placed upon the projecting end of the nipple, if desired. In the wall of the tube G is formed one or more than one opening, i, and a transparent pane or lining, H, is inserted so as to cover Vsaid opening oropenings, by means of which the flowing current of milk may be seen as it is discharged from the can through said tube.

lI he large chamber lying above the partition C, together with the contracted portion or portions E, constitute a cooling apparatus which is adapted to contain as many cans or milk-vessels as there are chambers or cylinders' E. y

The refrigerating material employed may be cold water runnin-g continuously through the cooling-chamber, or water may be used which is cooled to the required point by ice, which is placed in the large upper chamber, thelatter also being filled with water so as to leave room for the addition of broken ice in proper quantity.

For the purpose of illing the coolingcham ber, an inlet-pipe, I, enters the case at its upper part, and near the rear wall thereof, as shown in Fig. l. This pipe has an elbowjoint, and is provided with a funnel, K, the arrangementbein g such that if desired a crea1nery may be so placed that said funnel will receive a stream of water from a faucet. A discharge-pipe, L, is placed at the other endof the case and near the front wall, being thus diagonally opposite to the inlet-pipe. Thus when cold running wateris used,it must travel over the greatest possible space before escaping at the outlet. 'When the cooling process is completed,it may be necessary to discharge the water from the cooling-chamber as well as from its contracted portion E. For this purpose I provide a discharge-pipe M, which drains the larger chamber above the partition C, while for each of the cylinders E a separate pipe, N, maybe employed.

In Figs. l, 3, and 4 of the drawings, it will be seen that the cylinders E, which drop below the horizontal partition C, occupy but a part of the space inclosed by the cabinet-casing A.

In reducing the temperature oi' the milk the refrigerating medium, whether it be running water or water cooled by ice, fills the cylinders as well as the enlarged chamber above, into which they open, and as the colder current constantly tends to flow downward, replacing the warmer portions as they rise to the surface, the fluid, which entirely surrounds each milk-vessel in each cylinder, will be main tained at the lowest temperature produced. This temperature is soon commu nica-ted to the inclosed space below the partition C, and after it is once established it may be maintained with but little expenditure of therefrigerating material,since the walls of the cabinet cut off all convection of heat from the outerA air. It is evident, therefore, that the inclosed space in the lower portion of the cabinet may be used as a refrigerator or safe for the preservation of cream, butter, or any other article. In this manner the reduction of temperature whichA is required in order to effect the primary separation of the cream from the milk is utilized for the preservation of perishable articles, while at the same. time the cabinetcasing not only forms the refrigerating compartment, but also has an important function in economizing the waste of the ice by inclosing the cylinders E, and thereby preventing access of air from without, which would greatly retard the operation and cause a considerable Waste of refrigerating material. For the sake of convenience,a shelf may, if desired, be placed within the casing below the pipes G, being made removable, so that the final separation of the milk may be effected conveniently.

rlhe arrangement of the cylinders E, and consequently of the milk-vessels within the cabinet,may be varied. In the style of creamery shown in elevation in Fig. 3 the cans and the cylinders in which they are inclosed are arranged in two ranks, t-he members of one rank being directly opposite those of another. Fig. 3 being in elevation, it must be understood that there is a second rank or row of four cylinders with their discharge-pipes leading from the contained milk-vessels arranged directly behind those seen in the drawings. In this style of Creamery doors P are placed upon both sides of the cabinet, in order to give the operator convenient access to the pipes G, by which the milk is drawn off, it being necessary to operate the discharge-pipes in the front row from that side of the cabinet, and then pass around to the other side in order to obtain access to those in the second row.

In the style of creamery shown in Figs. 1 and 2 the cabinetis provided with doors upon one side only. In this construction the cans and the cylinders which contain them are alternated, as shown in the plan View of Fig. 2. By this arrangement the center of each cylinder in the second seriesis brought nearer to the front of the cabinet; and, furthermore, each member of the said series being placed between the cans in the front rank, the illuminated discharge-pipes are in view from the front of the cabinet. These pipes being placed nearer one side of the can, as before described, they are easier reached and operated from the front of the cabinet, and doors I" are therefore placed upon that side only. This style of Creamery is convenient on many accounts, particularly in small dairies,since by the alternate arrangement of the cans the cabinet-case can be made of less width. Being less bulky, it can be more easily moved and occupy less space. Moreover, it can be placed with its back against a wall, which is a consideration of some importance in buildings where space must be economized. In raising cream by this apparatus the milk is placed within the can or cans F, each being provided witha cover having a Ventilating-aperture, m, corresponding ventilators being placedupon the lid of the cabinet, if desired. The cooling-chamber is then filled with water,which occupies a space between the walls of the cylinder or cylinders E and a milk-vessel contained there- 1n. and to rise into and partly iill the enlarged' cooling-chamber above, room being left for a suitable quantity of broken ice. Then the cream has risen, it is separated from the milk by drawing the latter o from beneath the former, the limit of outflow being determined by the apperance in the illuminated dischargepipe of cream-akes, which are borne by the last portions of the escaping milk.

The entire mode of operation of the creamraising and milk-separatin g apparatus is identical with that set forth in my Reissued Letters Patent No. 9,156.

Instead of the cylinders E, asingle continuous chamber may be formed, opening from the bottom of the larger ice-chamber and running from end to end like a trough. The milkvessels may be placed side by side in this contracted continuous chamber, and as close to each other as desired. I regard this form of construction as the full equivalent of the separate contracted chambers or cylinders E.

I am aware that heretofore a cream-raising apparatus has been used, consisting of a deep cylindrical milk-can having its upper portion only surrounded by an ice-box or water-tank, said can being secured to the bottom of said tank in such a manner as to forma water-tight joint, the lower portion of said can dropping below the said ice-box or water-tank into the lower compartment of a cabinet-casing inclosing the Whole of the above-described apparatus. This class of cream-raising apparatuses is constructed in accordance with what is known as the current theory 7 of cream-raising, which holds that the primary separation of cream from milk is effected rapidly by applying the refrigerating material to the upper part only of the milk can or Vessel containing the milk, and at the same time expose' the lower part of such vessel to awarm temperature. I broadly disclaim such construction.

Vhat I claim isl. A cabinet-casing provided with an upper and a lower compartment, the upper compartment serving as the cooling-tank and having a depending well extending into the lower compartment, in combination with a milk-can supported in said well, substantially as specified.

2. A cream raising and refrigerating apparatus united in a single structure and consisting of a cabinet-casing, an ice receptacle or chamber arranged in its upper part, one or more water-chambers depending from the icel receptacle into a lower compartment of said cabinet casing, and a milk vessel or vessels contained within and wholly surrounded by the ice-receptacle and the Water chamber or chambers depending therefrom, whereby the refrigerative action of the agent employed in the Sufficient water is used to fill these spaces IIO primary separation of the crean] is utilized in the lower compartment for general purposes, substantially as specified.

3. In a dairy-Creamery, the refrigeratorbox having the contracted lower portion forming a Well depending into a lower compartment of a cabinet-casing including said refrigerator? box, in combination with the nlilk-reoeiving can secured Within said Well and extending upward through the refrigerator-box, the lower end of said can being provided with a nipple extending through the well into a lower compartment ot' said cabinet-easing, the space between the can and the box and the well being continuons and uninterrupted, as and for l the purpose described.

4. In a dairy-Creamery, the combination, with a cabineteasing having doors upon one to this specification inthe presence of two sub- 3o seribing Witnesses.
