SPECIFICATION forming part of Letters Patent'No. 641,351, dated January 16, 1900.

Applioationiiled September 7,1897. Serial Nol 650,766. (No modell) To @ZZ whom it may concern:

Be it known that I, MIoHEL WILLETT, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Refrigerators, of which the following is a specication.

My invention relates to refrigerators wherein the air within the same is caused to circulate directlyv from the storage-chamber up to and through the ice of the ice-chamber and back tothe storage-chamber, thus cooling the air by direct contact with the ice instead of by radiation and causing a marked variation of temperature to provide an active circulation of cold air Within the storage-chambers.

the ice-chamber from the storage-chamber or to the storage-chamber from the ice-chamber, and the latter has not been properly protected against the suction and surging of the for correcting said defective construction and improving such devices, as will hereinafter appear.

In the accompanying drawings, Figure l is a transverse vertical section, and Fig. v2 a.

central longitudinal vertical section, of a refrigerator embodying my invention.

` The Walls A of the refrigerator are made in a suitable manner with dead-air spaces a and Ct therein, the former, a, extending up the sides only and the latter, a', extending upon the inner sides thereof and also across the top of the refrigerator-casing.

Along the side Walls B of the refrigerator are placed studding b and Z7', the studding b at the four end corners of the storage-chamber C extending from the floor up to thetop of the storage-chamber to support the ends of cross-beams D, one at each end of the chamber, upon which the ends of the strips forming the ice-grating F of the icechamber E rest, and are secured at equal graduated distances from each other. The intermediate studding b' extends up to the full height upon the sides of the refrigerator, and awall 6o or casing h, secured to the inner edges of the studding b', provide side passages H forthe air to pass from the upper end of the storagechamber to the top of the ice-chamber, and the said Wall or casing is then continued over the ice-chamber at h to provide horizontal air-passages H' over the ice-box. The airpassages H extend from the side passages H to the middle part of the top cover to the icechamber and to a central longitudinal aper- 7o4 ture I therein, extending from one end to the other of the refrigerator, which serves to admit the air which has passed through the said side and top air-passages into the ice-chamber at the central portion and throughout the entire length thereof, to be thus distributed evenly over the entire upper surface ofthe body of ice within said chamber, and then pass downwardlythrough the sanneand around all sides of each blockv of ice and thence out in 8o an evenly-distributed manner through the grating in the iioor of the ice-box.; To checlr` and better regulate the passage of air through the grating and to carry off thedrip-Water, I provide two pans K, which extend from one end of the storage-chamber to the otherthe full length of the grating and from the side Walls to points at suitable distances from the central longitudinal line thereof, as clearly shown in Fig. 1. o

The outer sides of the pans are hinged at 7c' to the side Walls vor studding at the upperend of the storage-chamber to hold the outer sides of said pans in close proximity to the bottom of the said grating, and the inner sides of the said pans K are ladj ustably connected by hooks 7a2, secured to the end Walls of the storage-chamber, which engage with any one of a series of staples k3 at the inner sides of the pans, by which means the inner sides of the 10o pans may be raised and lowered or adjusted to provide more or less opening for the pas'- sage of air downwardly from the ice-chamber between the inner adjacent sides of said pans. The inner sides of the pans are preferably placed about eighteen to twenty inches the center of the refrigerator, and each pan has a shelf M, made of sheet metal and supported upon wedge-shaped blocks m, secured like vertical partitions transversely within the said pans, which support the said shelves in an inclined position thereon, sloping from the center within the edge of the cover-plate L downwardly a suit-able distance from the sides of the said pans to admit of a suitable circulation and passage of air and drip-water around the ends and beneath the said coverplate, the drip-water being thus conducted in a reverse direction over a greatly-extended surface distance to thus aid iircooling the air passing over and around said drip-conveying surfaces, and the inner ends of the shelves M are helda suicient distanceabove the edges l of the inner sidewalls of the pans K to allow the air to pass freely upon the bottom of the pans below the said plates and at the inner adjacent sides thereof down into the central portion and equally through entire length of the storage-chamber. y

I claim as my invention and desire to secure by Letters Patentp 1. A refrigerator comprising a storagechamber, an ice-chamber, air-passages eX- tending from said storage-chamber around the said ice-chamber and pans affixed to the side walls of the storage-chamber to incline downwardly toward the central part of said chamber, each havinga shelf inclined down- ,wardly from near the inner to near the outer sides of said pans, substantially as described.

2. A refrigerator comprising a storagechamber, an ice-chamber, air-passages extending froin said storage-chamber around the ice-chamber, pans affixed to the side walls of the storage-chamber toineline downwardly toward the central part of said chamber within a suitable distance from each other, each having a shelf inclined from near the inner l thereof, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in the presence of two subscribing witnesses.

MICHEL WILLETT.
