" To all 'whom ity/may concern:

Be it `known that I=,'DANIEL E. Soms, of

l Washington, in the county of Washington I and in the District of Columbia, have invented a new and useful ImprovedItefrigerating and `PreservingApparatus; and I do hereby declare that the following is a full, clear, and

. exact description thereof, reference being had `tor-the annexed drawings, making' part of this .specifica-tion, `in which- Figure 1 is a plan view of my improved refri gerating and preserving apparatus, the head of the ice=receptacle and portion ofthe upper f wall of the preservingfbox being removed to.' y show theirinterior; arrangement.

My invention relates to a refrigerating and preserving apparatus; and my improvements 'consist 1n sundry peculiarities of construcfl tlon and arrangement of various parts, as will be more speciiically set forth in the following 'i specicationand claims. e

' To enable others skilled in the art to make and use my invention, I will'proceed to de` scribe its construction and operation.

In the annexed drawings, A represents theV ice-receptacle, andfB the preservingbox, the

former of which is setinto the latter, having no connection therewith, excepting through valves or cocks A5. Vhen the ice-receptacle projects above the top ofthe preserving-box, as I have shown in this instance, such Apro- I valve.

j Vecting part is constructed with multiple walls, the spaces between which may be filled with air,or some good non-conducting substance, as

charcoal, cotton, tow, and the like. Around the innermost wall 1 prefer to construct i'lues, which are always left open for the airto circu late through, and may communicate through registers a in the head A1 with the exterior atmosphere. These iiues are marked A2 in i Figgl. A3 is an independent flue or pipe ex'- tending from. near the top of the preservingbox upward through the head of the ice-receptacle, being provided with a suitable damper.

This pipe is used for introducing fresh air into the ice-receptacle, and may be used in connection with a cock or valve, A,Figs. 1 andv 4, t'o cool the atmosphere in the room in which this apparatus is placed, warm air constantly ,falling down through the stack to take the place'of cold air discharged through the a single wall, so that its temperature may be readily transmitted to the latter. Valves or cocks A5 serve to open or close communica-- tion between the ice-receptacle, and preservV` ing-box. A6 represent diaphragins or grates,

placed at di'erent altitudes in the ice-recep tacle, for the purpose of supporting the ice 'or other cooling substances at different heights V therein,all the diaphragms being made so that they can be removed out of the receptacle.

The preserving-box may be made of any l suitable size and form to suit the various conditions under whichit is to be used. Allrirtswalls are made multiple, packed between with good non-conducting substances.

e vAll aroundv the ice receptacle are placed tanks or boxes B1, of convenient size and form, and either rigidly secured in the preservingbox or loosely set into the same,so` that they can be removed therefrom. In the latter case they are providedwith iianges around their upper ends, as show n inl the .right-hand section of Fig. 4, such flanges being provided on their upper and under'surfaces with a con-V tinuous groove, somewhat fiat, in which rubber tubes or other packing are fastened, for the purpose of making the joints between the flanges and the preserving-box, as well as between such iianges and the doors or lids which That portion of the ice-receptacle within the preserving-box is constructed with y 2.', lomesn close the tank, air-tight. I prefer toemploy .theserubber tubes in every case where open.: ings are made in any part of the apparatus,

and closed by doors or lids.

The tank-s, whether rigidly connected tothe preserving-box or yset loosely into the same,

j must always be made water-tight, and no communication must exist between the two.

In any convenient part' of the preservingbox I propose to insert an ice-cream freezer,

' C, consistingof a ,cylinder of suitable size,

made of sheet metal by preference, in which an agitator, ,01, is pivoted, extending some of the cylinder, as

- tending-a short distance through the same to receive .a bevel-wheel, C3, which meshes into and is driven by 'another bevel wheel, C4, mounted upon a horizontal shaft, placed in suitable bearings, and having a crank or other device upon its outer endby which to turn it.

The otice of the box C2 is to receive lumps of ice, ice and salt,` or other cooling substances,

for the purpose of freezing the cream in the cylinder independent of lthe other parts of the apparatus.

The cylinder C is inclosed by an open or lslotted case within the preserving-box, and i prevented from'turning by anges c' upon its periphery, which take into grooves formed in the inclosing-case.

The beaters upon the agitator-spindle are in the form of screws, so that in turning the 'agitator in one direction theypress the contentstoward the bottom of the cylinder; but on turning the same in the opposite direction thy tend to lift the contents out of such cylm er.

. D is another vessel set into the preservingbox, which is to receive water to cool the same, it Ibeing provided with a discharge-pipe in its lower portion, extending through the' side wall or bottom of the preserving-box, andprovided with a suitable cock, as showndn Figs. land 2. Y .Y

Afaucet is arranged in the bottom of the preserving-box at B2, Fig.`1, by which to draw;

oi any liquids whichit may be desirable to Pipes E and E oxtjomii through tho bottom of the ice-'receptacle to different heigh ts,`asshown,through which to discharge the water or other liquids therein. They are provided with traps and cocks on the outside, the traps being for the purpose of'preventing the escape of the cold air from the ice-receptacle.`

This apparatus may be operated in thefol- -lowing manner: C lhe preserving-box, when af very low temperaturel isl wanted, is filled,

.through suitable openings in its top, with ivater or brine, which surrounds the ice-receptacle, tanks, ice-cream freezer, and wzucfcooler upon all sides. he upper diaphragms or grates-.in the ice-receptacle are then taken out of the salue, and a suflicie'nt quantity of ice or other cooling substances placed upon the lowest grate. Very soon a very low temperature willjbe obtained in the preservingbox, which temperature soon reducesv the air in the tanks to the same js'tate. 'A low'temperature can thus be maintained, with little expense of ice,i11 the various ltanks and other devices inserted into the preserving box. Sometimes such a low temperature is not desirable. The brine is then removed from the preserving-box, and air' only used. In this instancey thetemperature in the preservingbox can be readily regulated by opening or -closing the cocks in the ice-receptacle. The

lower portion of the ice-receptacle is generally tobe lled with brine, the level-of which can be determined by the discharge-pipes.

. In the application of my invention to preserving-houses and packing-houses, and the 1ike,the stack or ice-receptacle may extend one story ormore above the'prcserving'box or chambers or salting-tanks, and be filled tothe top, thus securing a supply of ice suflicient to last'several months, or an entire year.'

- When used for cooling buildings or apart ments, and Ventilating the same, the air, as'it falls through the flues or pipes A? and A3, is conducted through the valve A4 to the different apartments to be cooled by means of tubes provided with valves for regulating the supply thereof.

The chambers or tanks maybe made of any suitable material; but glass, made independ' ently of thei other parts of the apparatus, with groove'd lian ges, as shown in Fig. 6, and placed within the case, is preferable.

Having `thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the preserving-box or refrigerating-'c amber, ice-receptacle, and icecream freezer, operating substantially as described.l

2. The combination of the refrigeratin'gchamber, ice-cream freezer, water-cooler, and Ventilating-tubes with an ice-box, substantially as set forth.

, 3. An ice-cream freezer with an ice-box.

forming the cover thereto, substantially as shown and'described.
