State of California, have invented a new and useful Improvement in Evaporative Cool- My invention relates to refrigerators designed to cool their contents without the use of ice.'
My object is to so arrange a refrigerator box or cooler as to produce a sufficient degree of frigidity by means of the rapid evaporation of running water, and l attain this objectby means of the apparatus illustrated in the accompanying drawings, in which-d Figure 1 is a vertical sectional view of my cooler on the line .vf- Figs. 2 and 5. Fig. 2 is a horizontal sectional View on vthe line :r2-m2 Fig. 1 looking upward with a portion of the top and water-table broken away.

evaporates; and at the same time providing an outlet into the atmosphere'for the warm air from the inner chamber.
I construct my cooler entirely of pottery or earthen ware slabs, which are porous with the exception of one of their faces which is glazed, the Vglazed faces being toward the food contents, and upon the outside ofthe cooler andv the porous faces exposed to the water and air, thus making the cooler sanitary and securing effective evaporation for cooling the air. 4'
In constructing the cooler I use the pottery base 4 with its outer face glazed and its inner face porous, and having formed in its inner face the double grooves 24 and 25 and 26 and 27 with the drain channels 22 and 23 therebetween and the small drainage holesA 28 leading from the grooves and the channel to the outer air. These grooves, channels, and holes are formed on the two sides and the back, and on theifront there is but one groove formed and no drainage 'channelor outlets. In the grooves 24 and 27 I set the side slabs 2 and l with their glazed faces outwardly, and in the grooves' 25 and 261 set the'wall slabs 5 and 6 with their glazed faces inward and their porous faces outward facing the outer slabs leaving chamber 36. The back of the cooler is set in the same manner. The porous walls of the chamber 36 may be fiat, or they may be corrugated or stepped as shown in the drawing, in order to afford a larger evaporating surface. face each other or be arranged alternately as shown in the drawing. The front slab 41 is glazed on both sides and has a'door opening 42 in it and the door 43 made similar to the side hung in the opening. The top slab of pottery 3 has formed around its edges on the porous face the shoulder 13 adapted to fit the top edge of the side slabs and in its center is formed the orifice 12. The inner walls 5 and 6 and the back inner wall 40 are shorter than the outer walls and are capped. with the water table 7 which. has formed on its glazed face the grooves 18 to fit the top of the side walls 5 and 6, and the rear wall 40. n the center of the top of the water table 7 is formed the shallow cup shaped depression 14 from which radiate the water channels 15 and 16 'toward i between the outside and Vinside slabs the The corrugations or steps `may to within an inch, more or less, of the edge, to holes through the table opening at the porous face of the inner Walls, being so arranged in alternate order. The face of the water-table slants slightly downward from the center to the edge, and the radial water channels have a similar slant. The outer edgeiof the water-table is slightly beveled downward, and the channels that extend to the edge follow this bevel. The holes 15" in the back, however, are larger so as to act as air inlets. The edge of the water table lits loosely the face of the outer walls and allows the water to ooze over the edge and down the porous inner face of said walls. The inner walls 5 and 6 have formed `on their inner faces the shelit` ledges 32 on which may be placed the perforated shelves These walls have also near their bottom the large openings 2O through which the cooled air enters the inner chamber. Having thus assembled the parts I clamp them securely in position by means of the bolts 34 and 35 andthen set it in the carriage 29 provided with the drip outlet() and the rollers 3l. On top of the cooler I .place the water reservoir 8 provided with the central conical outlet l0, the filter 11, and the cover 9. This reservoir is also made of pottery and has the legs l which'allow an air space between it and the top of the cooler. The orifice l2 is larger than the cone l0 and allows the passage of air into' the top of the cooler whence it passes over the water table and down through the inlets i5.
In operation the water Will filter from the reservoir 8 through the outlet l0 and drop into the cup 14 which as it overflows will pass the water through the channels l5 and 16 thus distributing it equally to the three sides of the cooler and allow it to drain equally through the holes l5 and 17 and over the edge of the water table down the porous faces of both walls of the air chamber. The air will be admitted through the air inlets l2 and 19 and passing down the Losaaia `air chamber will evaporate the Water and4 thus become cooled and then pass through the openings 20 into the inner chamber, forcing the warm air out of the chamber through the outlets 2l.
Having thus described my cooler, what l claim as my invention and desire Letters Patent for, is-
l. An evaporative cooler, comprising detachable spaced inner and outer walls top and base of .porous stone or similar substance the inner faces of the inner walls and the outer faces of the outer Walls being glazed and the adjacent faces of the Walls being left porous, providing air and water chambers between the walls, air inlets and outlets, water inlets and outlets, a radially grooved water table on the top of the cooler communicating with the chamber, a water reservo-ir communicating with the water table, a food chamber inclosed by the walls and means to connect the same with the air chambers.
2. in an evaporative cooler, the combination of detachable, spaced inner and outer walls, top and base of a porous substance, the inner faces of the innerwalls and t-he outer faces of the outer walls being glazed and the adjacent faces being porous, air and water chambers between the walls, a radially grooved water table on the top of the inner walls communicating with the chambers, a water reservoir communicating with said water table, a' food chamber inclosed by said walls, means for the admission of cool air and the emission of Warm air from said chamber. means for the supply of water from said reservoir to said water table, water passages through said water table, .means for the absorption of water by the inner and outer walls, and means for draining the surplus water.
