Letters Patent No. 100,683, dated March S, 1870. y y e IMPROVEMENT IN APIARATUS FOR. COOLING AND PRESERVING.

The Schedule :eferredito in these Letters Patent and making partof the same.

-....pQ--n- Tosall whom 'it may concern.

Be it knownthat l, DANIEL E. Soares, of Washington, in the county ot Washington, and in the Dis-I trict of Columbia, have invented a new and useful improved Refrigerating and lreservi11g-Apparatus;

'audI do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the annexed drawings making part of this specification, in which- Y Figure 11 isl a plan view of the apparatus, the head of the ice-receptacle, and a portion of the tcp wall of the'box in which the tanks are arranged being broken away to show the interior arrangement.

Figure 2 is a central vertical section of the same. Figure 3 is a plan view of the apparatus, showing' a different form of the preserving-box, and also pipes inserted in the s. id box at different points, communi eating with its interior, and ca1rying,at their upper outer ends, reservoirs for water, which is made to trickle down upon some porous covering around the pipe to produce evaporation.

Figure 4 is a sectional clevi'ton of the same.

The same letters are used in all the figures inthe `designation of identical parts.

My invent-ion relates to an apparatus for cooling and preserving perishable articles, and my improvements consist in the construction, combination, and

arrangement of various parts of the device, as will be more fully set forth in the following specification and claims.

To enable those skilled in the art to make and use my invention, l will proceed to describe its construction and operation.

In the annexed drawings- A represents the icereceptacle set into the surrounding preserving-box B. I have shown a portion of this receptacle as rising 'above the top ot' the box B, in which case the project-ing part is constructed with double or multiple walls, the spaces between which may be filled with good non-eolulucting material.

The top ofthe ice-receptacle has a hinged head, closing a suitable opening through which to pass the ifcewor other cooling substance into theysame. 'lhat portion of the receptacle within the box B has onl ya single wailhias shown.

Diapln'ag'ms or gratcs A are arranged in the ice-receptacle at different heights, and so that they 'can be withdrawnfout of the same, so that the 'cooling substances can be supported at various points.

,A trarne?, serves to discharge the water fromthe receptacle at any time it is desirable to do so. without jthe reservoir upon a lining of to material, wound around, iuteriorlyor exterior-ly, the

tanks or receivers, G, either set loosely into the same,

through openings in the top wall of said box, or per,- ni'anently built in it. In either case they are to be so arranged as to leave spaces between them and the walls of the box B and the receptacle A, and they must be constructed water-tight. v

These tanks aretobe' closed on top by suitable doors C, the joint between which and said tanks is made air-tight by rubber-tubing c inserted between the two.v

A trap, B', is used for drawing ofi' the liquid ordinarily contained in the box B.

I) represent pipes inserted in the box B at differ# ent points issuing into the same between the tanks.

y They extend a short distance into said box, so that their lower ends, which are open, are below the level of the water or brine contained therein.

, A lheir upper ends, which may rise to any desired height above the top of the box, are also open, and

upon this end a reservoir, D', of suitable size, is arranged, in which to storewater or other liquid, cocks ll being used to allow theliquid toptrickle dowirfrom 'or other iexible pipe, whereby evaporation is produced inthe pipes, and the air therein constantly cooled, the temperature of which is transmitted through the water or brine in th'box B to the tanks or receivers C.

This apparatus may be operatedrin the following manner:

The preserving-box B is nearly illed with water or brine, which surrounds the ice-receptacle and, the tanks or receivers, in which latter the articles to be cooled or preserved are placed; The ice receptacle' `is also partly filled with brine or water or not, as circumstances may require, and a suicient quantity of ice or other cooling substances placed in the "same to reduce the temperature.

I do notconiine myself to the varrangement of the parts of the apparatus, nor to the number of' evap orating-pipes or ice-receptacles. I also may use the ice-'receptacle as an evaporating-pipe, covering itsinnero'r outer sides with porous substance, and having a tank of water to wet the same, against which a stream of air is forced to produce evaporation, as shown in fig. 4, or jets ot' wateror other liquid, or iine spray may be forced against it.

A pipe Amay be placed inside or outside of the preservilxg-chambers, communicating with allv and terminating at a common opening to let out the acc-umulations of water,- or for-the admission of'v air, though for most purposes the chambers will be sniiiciently dry, and will not need to be ventilated.

Having thus described my invention,

What l claim, and desire` to secure by Letters Patent, is-

1. In combination with a. refrigerator, one or more evaporating-pipes and blower, or equivalent, substantially as and for the purpose set forth.

2. An ice-receptacle, having a series of removable perforated diaphragme or gratos, atintervlils one above the other, for the purpose oi' separating the ice from the liquid, thereby securing a lower tem'peral ture and economy in the use of ice.

3. A refrigerator with preserving or reii'igerating chambers, surrounded hy or partially submerged iu brine or other liquid, which is cooled by ice, ice aud salt, or other oolfl substance placed in mi ice-receptan cle, also partially submerged in the same body of liquid, and extending above the top of said chambers, said extension being covered with fibrous material, as and for the purpose set; forth.
