SPECIFICATION forming part of Letters Patent No. 727,215, dated May 5, 1903.

Application filed September 16, 1902. Serial No. 123,582. (No model.) I

To all whom, it may concern:

Be it known that I, HARRY J. SHANNEN, a citizen of the United States of America,an'd a resident of Atlanta, in the countyof Fulton and State of Georgia, have made a certain new and useful Improvement in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the said invention, such as will, enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to figures of reference marked thereon, which forms a part of this specification.

This invention relates to refrigerator-cabi nets, the particular object of the invention being to provide a refrigerator construction which will be better than those heretofore devised and especially adapted to the larger market-refrigerators, where low temperature, economy, good circulation, and purer atmospheric conditions are more necessary than in the ordinary household or smaller refrigerators. 4

To these ends the invention consists of the device hereinafter set forth, and shown in the accompanying drawing, in which the device is illustrated in section vertically and transversely of the ice-rack, watersheds, and traps;

The casing or walls 10, inclosing the refrig-i erating and ice chambers, may obviously be of any approved construction, insulation, &c. The ice-rack 11 is situated in the upper portion of the casing between the refrigerating and ice chambers and should be removable either in sections or as a whole for cleansing, 850. The upper water-circulating shed 12 consists of a roof-like structure sloping downward laterally from the center and secured just below the ice-rack, being so nearly coextensive therewith as is possible and being adapted to catch practically the entire drip :from the ice and circulateit over as large a being separated at the center and forming a cold-air port at the center and lower portion of this shed 13. On the inner edges of the tion of its surface as possible. the elevated outer edges of this shed 13 are two constituent sides of this shed are dams i. 14 to obstruct the flow of watera'nd permit it to 'run into the pipes 15, converging into the The shed 13 also has the structural requisites to circulate the water over as large a propor- Just below troughs 17, the side boards-18 of which opposite the said shed are higher than the outer edges of the said shed, saidt'roughs 17 lying about centrally under the outer edges of the shed 12 and being adapted to hold water dripping from along the" said edges and become therebyfilled, overfiowingupou the shed 13, :thence downwardly over same to the inner or lower edges, thence to the drainage-pipes. The outer sides of the side boards 18 are a short distance from the inner sides of the walls or casing 10, and just above said side boards are inclined boards19,secured to the said side walls and projecting, either through the medium of boards 20 or themselves, downwardly'to form deflectors forthe warmer-air currents arising from the refrigeration-chamber through the openings between the side boards 18 and the side wallsaforesaid, whereby said warm air is deflected and forced to pass in contact with the cold water in the troughs, being thereby cooled and purified before passing upwardly between the edges of the shed 12 and the said boards 20, thence to the ice-chamber for final cooling, and again going downwardly in their circulation. Obviously the air when" cooled flows downwardly through the slats of: the ice-rack, ithence over the shed 12 in contact with the cold water circulating thereover, and thence through the opening between the edges of the shed and likewise over the shed 13 and downwardly through the cold-air opening in the shed 13 after passing over said last-named shed in contact with the cold water, thus thoroughly cooling and purifying said air beforeit is finally returned to the refrigerating-chamber.

Holes shown at 21 in the drawing serve as raking-holesto clean out thetro'ughs, and it is plain that all solid matter falling from the ice-rack will be collected in said troughs and be thereby prevented from stopping up the water-discharge pipes or overflowing the refrigerating-chamber. The water held in suspension in the air is condensed by thus passing over the cold water, and proportionately drier refrigeration is obtained.

Having thus described myinvention, what I claim as new, and desire to secure by Letters 5 Patent of the United States of America, is

In a refrigerator, an ice-chamber and a refrigerating-chamber formed of side Walls, top

and bottom, and divided the one from the other by an air-circulating and drip-catching 1 o diaphragm consisting of a horizontal ice-platform a double watershed sloping downwardly from its center laterally and terminating short of the side walls, narrow watersheds extending from said side walls to a point short of the 15 edges of said double watershed, downwardlyprojecting flanges on the lower inner ends of
