To all whom t may concern,.- A`

Be it known that I, MARTIN B. MILLER, re-A siding at Omaha, in the county of Douglas and State of Nebraska, have invented certain useful Improvements in Automatic Cream- Coolers; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form aA part of this specification. g

This invention has relation to a new and novel improvement in automatic creamcoolers.

The object of my inventionis to provide a tank adapted to contain cream and within which tank is to beheld a cooling-coil adapted to be carried gently through the cream to cool the same; and my invention embodies the combination of certain instrumentalities, as will be described more .fully hereinafter and finally pointed out in the claims. I

In the accompanying drawingsIhave shown in Figure 1 a side elevation of an automatic cream-cooling tank embodying my invention.Y Fig. 2 shows a top view with portionsre moved. Fig. 3 showsa centralsectional view, while Fig. 4E shows a detached detail disclosing the arrangement of the cooling-coil and the connected float.

Myinventionembodies,essentially,awatertight trough supported by means of the legs 2 2 and embracing the ends 1 1, the sides-A,- and the bottom 3, as disclosed. Extending from this water-tight trou gh is al suitable stopcock 4, as is disclosed in Figs. 1 and 3, located near the bottom, while preferably at the same end and above the stop-cock is an escape-pipe 5. This trough is adapted to contain a cream-holding receptacle or tank B, preferably provided above with the outwardly-flared edges c, by means of which this tank is heldfwithin the trough'A. This tank is preferably flared inward, so that the bottom area is smaller thanthe upperend of the tank, as will be understood in referring to Fig. 3. Extending from the bottom of this -tank B, adapted to contain the cream, is a suitable stop-cock 10, so that this tank may be drained.

Z. Serial No. 93,719. (No model.)

troughisa central cover 7, to which are secnredtih'e lids S, reinforced by means of the grates, as is clearly shown'in- Fig. 3; L'Located upon the central top portion G is a water-tank F, from which tank extends upward apipe c, (shown in the top view in Fig. 2 and in a dotted elevation in Fig. 3,) this pipebeing in open communication with the water-tank F, so' that the water rising within the tank will yalso rise within this cohnected tube or pipe c. From a pointpreferably opp'osit'e'the intake- `point of the tube or pipe c extendsa Siphon H, which siphon is also in open communication with this water-tank F, and this siphon is direct-ed into the lower water-tank A, as is disclosed in Fig. l, where the dotted end of the siphon His disclosed. Accordingly when the water riseswithin this upper tank and findsan escapement through the siphon II the siphon will be primed and so empty'this 4upper water-tank F. This tank'Fis preferably roundth`o'ugh'it may be of any suitable conformation, and held therein is a suitable Iioat C of a predetermined lifting capacity, from 'which project upward and thence downward l.the supporting-brackets b, so positioned that l,they extend upward over the edge cf the watertank F and downward through suitable openings within the coverings 6 and 8 almost to the bottom of the cream-holding tank or receptacle B, as is clearly shown in Fig. 3. Below these brackets b are secured to the bars 12 l2, which in turn are secured to the cooling-coil D, comprising a plurality of connected tubes of a length almost the length of the cream'- holding receptacle and being coiled from end to end, as is shown in Fig. 2. The capacity of the float C, which may be a copper tank or be composed of any other suitable material, is in excess of the work of the cooling-coil D and the bracketsv b. Oneend of this cooling-coil D is extendednpward to provide the termination 13, as is shown'vmore clearly in Fig. 4, while the remaining-tend terminates in the gooseneck 14', which gooseneck is adapted to work withinthetube c, as is shown in top view in Fig. 2 and indotted lines in Fig. 3. is positioned a suitable wa ter-supply tank 18, from which extends an elastic tubing l7-as an Extending transversely across the top of the ordinary garden-hose', for instance-the end 4.Adjacent this water-tank F ICO of which is secured to the upward coil extension 13, which passes through a suitable opening within the top 6, as does also the gooseneck 1-l.

Now in the use of my cream-cooler the operation would be as follows: The cream to be cooled would be placed within the cream tank or receptacle. The cooling-water from the tank 1S would next be permitted to llow rose in this tank it would rise within the Siphon I-I, as well as raise the float C and the conn ccted cooling-coil D, secured to the same by the brackets b. In gently rising through the cream the cream would be gently agitated and cooled by the flowing water passing through the same, and this coil would rise upward a suitable height, determined by the overflow of the water through the siphon II. As soon as the siphon II was started the water would Iiow out of the tank F, the siphon being made of a larger capacity than the intake water supply entering the tank F through the gooseneck 1st, the instru mentalities being so arranged that the coil D would descend at about thesame rate of speed that it rose until the water-tank F was emptied. During the period of the siphoning it is of course understood the water-supply is continually entering this tank F through the pipe 17 and the coil, as has been described. Now as the tank F gradually Iilled up again the coil would be carried upward, so that this cooling-coil D is continually operated upward and downward to be carried through the cream to cool the same. However, the water which was first made to circulate through the coil D to cool the cream and thence raise the coil would be still used, in that it would next ll the space between the trough and the cream-tank B, rising between the same until it found an outlet through the pipe 5. From this it will be n0- ticed that the stream is used twice to cool the cream and, in addition, made to operate the instrnmentalities to raise and lower the coil. Vhile I have described the water as being drawn from the tank 1S, it is of course linderstood that the tube 17 would be in connection with some suitable water-supply-as a city service, for instance. Now after the cream has been suiiicientlycooled the operator would open the stop-cock 10 and draw oit the contents, so that the tank would be given a thorough cleansing. The coilD being buta simple tube it can be easily cleaned, and so, also, it should be remembered that the tube 17 be placed in connection with a warm or hot water supply, so that, if desired, the cream or other batch within the receptacle or tank B could be raised in temperature, if that were desired.

The device is neat and simple of construction, and the working effects are so arranged that they may be easily cleansed, and

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

1. The combination with a suitable trough having an outlet, of a tank held within said trough, a water-receptacle above saidtank, a Siphon extending from said receptacle and emptying into said trough, a float within said water-receptacle, a cooling-coil secured to said float, one end of said cooling-coil being in connection with a suitable intake, the remaining end connected to said water-receptacle.

2. The combination with a trough, of atank held within said trough, an exit-pipe extending from said trough, a drain-cock secured to said tank, a water-receptacle secured above said tank, a siphon extending from said water-receptacle and entering said trough, a cooling-coil within said tank both ends eX- tending upward, one terminating in a gooseneck connected to said water-receptacle, the remaining end being in connection with the Water-supply, and a float within said waterreceptacle secured by means of brackets to said cooling-coil, all arranged substantially as and for the purpose set forth.
