REFRIG SPECIFICATION forming part of Letters ERATOR.

Patent No. 286,084, dated casona 2, ieee.

Application iiled Tune 20, 1883. (No model.)

To all whom t may concern:

,le it known that we, James SMITH and 'lL-ivm E. BLAKE, oi' St. Louis, State ot Missouri, have invented certain new and useful VImprovements in Refrigerators, oit' whieh'the ibllowingfis a `full, clear, and exact description.

Our invention consists oi' au improved refrigerator constructed to cause perfect circulation of air from and to the ice box or chamber through the provision-chamber, and pro vided with means for regulating the current or rapidity of circulation, whereby economy in the consumption oi ice may be effected.

Reference is to be had tothe accompanying drawings, 'forming a part of this specification, in which similar letters ol' reference indicate corresponding parts in both the figures.

Figure l is a longitudinal sectional. eleva tion of our new and improved refrigerator, taken on the line .r t oit' Fig. 2, and Fio. 2is a transverse sectional elevation tak en on theline jl/ fz/ of Fig. l.

A A are the inclosingwalls ofthe reti-igen ator. These are shown as plain wooden walls oi' single thicknesses of boards 5 but they might be made double and packed with non-conducting material, if desired.

)i is an inclined partition of rods or slats, which separates from the main provisionchamber C the ice box or chamber l), into which the ice is placed through the door E.

Above the provision-chmuler C is formed, by the horizontal partition F and the top of the refrigerator, the ai r-passage G, which leads back to the icebox D, and is made the whole width of the provisioli-chamber.

Beneath the provision-chamber C is formed, by the slatted bottom H and the bottom of the refrigerator, the airpassage J, which leads back to the chamber K beneath the ice-box D, and is also made the whole width `of the provision-chamber. This chamber K, beneath the ice-box D, is formed by the slatted and perforated bottom L ofthe ice-box and the inclined sheetinetal partition M, and in it is placed the receptacle or trough N for receiving the drip-water from the ice-box, which water is conducted away by the siphon-pipe O. The inclined board l? (also placed in the chamber l) serves to conduct the drip-water as it 'falls from the bottom L oi' the ice-box to the trough or receptacle N, and this board is so arranged above thetrongh that cold air from the icebox may pass between it and the trough down into the chamber l( below. From. this chamber the cold air that thus descends from the ice-box will pass (provided the door Q is not closed) into the passageJ beneath the provision-chamber, and from this passage will gradually iind its way up through the slatted iioor H into the provision-chamber C, as indicated by the arrows in the drawings. This cold air thus entering the prevision-chamber, coming in. contact with the provisions therein, will absorb heat, cooling the provisions, and becoming warmer and lighter from the heat taken up from theprovisions will ascend and (provided the door R is not closed) will pass into the passage G- above the chamber C, through which it will pass back into Contact with the icc contained in the box l). From this contact with the ice the air will be reduced in temperature and will pass from the ice-box through the slatted partition B again into the provision-chamber, to again exercise its cooling eit'ect, and. becoming again warmer and lighter from contact with the provisions, will join (as indicated by the arrows) the current continually coming from the passage J, and will pass with it again to the passage G, thence back to the ice-boX, to repeat thesame course, and so on continually.

The valves O and R are provided for the purpose of regulating the current or rapidity of circulation of air in the refrigerator, and these may be adjusted from the outside of the reirigerator, the former by the rod S, the latter by chain T, attached to them, respectively, so that by drawing outwardly upon the rod or chain, or releasing them, the openings to the passage J G may be entirely closed or entirely opened, or more or less opened, to increase or diminish the circulation of air, as desired, and it is designed, in some cases, to attach the chain T to the upper part, a, of the door U, so that whenever the door is opened it will close the valve R, stopping the circulation until the door is closed again, when the valve It will open. By properly manipulating these valves great economy in the use of ice may be effected. The d oor U to the provisionchamber O is IOO inade in two parts, the upper part, a, and the lower part, b, whiohlatter is wider than the,

upper part, and the upper part, a, is made to open independently of the lower part, b, so that in oase a small article is to be placed in or removed from the refrigerator it may be passed through the upper part, a, without opening the lower part, I), thus avoiding the escape of large quantities of cold air from the refrigerator.

Having thus described our invention, we claim as new and desire to secure by Letters Patent` 1. In a refrigerator, the combination, with rthe outer easing, A, of the inner provisionohalnber, C, having the valve R, the upper air-passage, G, lower air-passage, J, the valve Q and its operating handled rod S, ice-chainber D, separated from the provision-chamber 2o by the inclined slatted partition B, having the imperforate downward extension M, substantially as and for the purpose set forth.

2. In a refrigerator, the combination, with the outer easing, A, of the inner provisionohamber, C, having the valve R, the upper air-passage, G, lower air-passage, J, the valve Q and its operating handled rod S, ice-Chaniber D, having the slatted bottom L, and separated from the provision-chamber bythe inolined slatted partition B, having the iniperforate downward extension M, the deileotor or drain-board P, and the drip-receptacle N, having the Siphon outlet-tube O, substantially as and for the purpose set forth.
