COMBINED REFRIGERATOR AND FILTER- Specification of Letters Patent.

Patented June 11, 1907.

Application filed June 26, 1906- Serial No. 267,300-

lb all whoirt iifmay concern.-

,Be'it known that I, JOHN Y. ARNoT, a citizen of the United States, residing at Oak- "having an upwardly extending flang 'land, in the county of Alameda and State of California, have invented certain new and useful Improvements in a Combined Refrigerator and Filter, of which the following is a specification.

This invention relates to a refrigerator and water cooler, the object of the invention being to provide an apparatus of this character by means of which articles of food may be maintained cool without the use of ice, and which will furthermore afford a supply of filtered drinking, water. y

In the accompanying'drawing, Figure 1 is a front elevation of the ap aratus; Fig. 2 is a vertical section thereof; Fig. 3 is a horizontal section on the'line AA of Fig. 1; Fig. 4 is a horizontal section on the line BB of eferring to the drawings, 1 represents a suitable base, preferably rectangular in form, e 2. Upon .said base is supported, by blocks 3, a

\ casing or refrigerator 4, having a bottom 5,

and side walls 6, preferably made of artificial stone, and a top 7 preferably made of wood. Within the rece tacle so formed is a food box 8,'falso prefera ly made of artificial stone, supported ,upon osts 9 of the same material. pThis box 8 1s closed at the top and bottom and on three sides, but opens at the front into the side of the main casing 4 where outward it is closed by a swinging door 10, of the ordinary construction of an ice box door, aving a metallic shell 11 filled with mineral 001 or other insulating material 12. Between the box 8 and the top ofthe refrigerator are four walls or fpartitions 13 which slope slightly the refrigerator and are formed. of porous stone of such nature as to ermit water to percolate slowly therethroug Each wall at the top is formed with a number of small channels 14 to admit of ventilation over the surface of {the .pvater, there bein thus providedfree circulation between t e chamber 15 formed by said walls and the remainder of the interior of the casin 4 outside the box 8. The top of this charm er 15 is closed b a cover 16 filled with mineral wool or ot er suitable material, which cover can be raised by handles 17. In the middle of this lid is a funnel shaped cavity 18 which is closed by a om the top of the box to the top of.

poured into the chamber 15. 19 is centrally perforated to permit the passage of the stem 20 of a float 21, the level of the top of the stem indicating the level ofthe water in. the chamber, and thejnecessity ofreplenishing the chamber with water.

stopper 19, by removing which water can be: The stopper The water ercolating throu h the porous walls of the c amber15 is art y evaporated on the outside .of said Wal s, thereby reducing the temperatureof the water, and of the whole interior of the refrigerator, thus enabling articles of food placed in the box to be preserved without the use of ice. The water vapor escaping through the apertures 23, shown in dotted lines. Any excess of water not thus evaporated dro s'down into the lower portion of the refrigerator whence it can be drawn off from. time to time by a faucet 22. This water having assed through the porous walls of the chem er 15 thoroughly filtered, and in fit condition for drinking, can be drawn off through the faucet 22.

This apparatus is ofgreat value in warm climates and in districts far removed from ice houses and in which'ice is diflicult to obtain, especially where the water is of an inferior quality, as it not only acts as a refrigerator, cooling articles placed therein, but purifies the water furnished as the refrigerating agent.

1. An apparatus of the character described, comprising a suitable casing, porous walls within the casing inclosing a water chamber, a food box within the casing the top of which forms the bottom of said chamber, means for supporting said food box at a distance from the interior walls of the casing, said casing beingconstructed to collect the water filtered .the interior walls of the casing, said casing being constructed to collect the water filtered through said porous walls, a centrally perfoseams rated stopper for closing the supply opening I hand in the presence of tWo subscribing Witto said Water-chamber, the walls having latnesses. eral openings at their tops to permit air to pass therethrough, and means for drawing oil I JOHN O 5 the Water filtered through said porous Walls, Witnesses: substantially as described.

In witness whereof I have hereunto set my BESSIE GORFINKEL.
