REFRl-GERATOR.

SPECIFICATION forming partof Letters Patent No. 289,83?, dated December 11, 1883.

Application led March 8, 1883. (No model.)

To all whom t may concern,.-

Be it known that I, JACOB B. HABTMAN, of Wooster, in the county of Vayne and State of Ohio, have invented a new and useful Improvement in Refrigerators, of which the following is a specification.

My inventionrelates lto certain improvements in the construction and arrangement of refrigerator-buildings. y

Refrigerators having some ofthe features described in connection with my invention havebeen heretofore used.

The object of my invention is to provide a simpler and more effective wall, and at the same time a better method of Ventilating the refrigerator than heretofore used.

My invention consists, first, in the use of a refrigerator-wall constructed with dead-air chambers, which have no connectionwhatever with the interior of the refrigerator, or with the Ventilating system thereof, or with each other, each dead-air chamber being separate and entirely surrounded by continuous sheathing of asbestus or other suitable material to resist heat, and the number of such dead-air chambers being proportioned to the degree'of heat -resistance required in any particular case. Heretofore air-chambers similarly constructed have been made to communicate with the interior of the refrigerator and with each other, and also to form a means of Ventilating the same. This method is objectionable because the ice is thereby more rapidly exhausted by means of the draft upon it, and by using it to cool the air of the air-spaces; and, further, by this communication the interior cooling-chamber is at the same time brought into closer contact with the external air. This defectI overcome by the use of absolutely-deadair chambers lined, severally, with suitable heat-resisting material and entirely disconnected with the Ventilating system.

My invention consists, secondly, in an improved device for Ventilating the coolingroom. This I accomplish by the use of ventilating pipes or. iiues wholly disconnected with the dead-air chambers within the wall. These pipes are open at both ends, and extend vertically from the bottom to theltop of the refrigerator, and'in their passage intersect pipes leading from the cooling-room at the top of the refrigerator, so that the air-current which naturally and constantly arises in the extert v nal Ventilating -pipes in passing over the mouths of the pipes leading from the coolingroom'cause a suction thereupon after the man- -ner'of a siphon, .which extracts warmth and ventilator at'the top. The inner surface of 7o this external Weathercasing, including the roof, is lined throughout with asbestus sheathing or other non-heat-conducting sheet lining. The open-air passage has no direct connection with the ice-chamber. I do not claim any part of this external Weather-casing, except the arrangement of internal non-heat-conducting linings and of a continuous air-passage disconnected from the interior, as above specified.

Referring to the drawings, in which similar letters of reference indicate like parts, Figure 1 is a vertical section of my refrigerator cut through opposite Ventilating-dues in the sides and top. Fig. 2 is a horizontal section of the same. Fig. 3 is a front elevation of a door of the same.

R, Figs. 1 and 2, is the refrigerating-chamber, in Which `is situate. near the top, an icereceptacle, I, from which a duct, t, conducts the ice Water into a reservoir, G, Which empties externally through a pipe, t, by the spigot s.

.A A are the two segments of an open hollow- Wall Which entirely surrounds the icechamber R. These segments are united and form the dead-air chambers-C C.

D D are opposite Ventilating-fines, which open externally at o o', and pass up through the hollow wall and top, where they intersect and pass over the openings E E from the ceil- IOO ing of the ice-chamber, and afterwardtera c are sheet linings of asbestus sheathing or othernonlieatcon'ducting material adj acent to the open hollow of the wall. y

X is the external weather-casing, with internal non-heat-conducting sheet lining a, of

asbestus sheathing or other suitable material continuous with the roof Z to the ventilator V. 3/ y are open air-passages between the weathercasing and refrigerator-wall. l

L, Figs. 2, 3, is a door into the ice-chamber, having flanges F F, overlapping the margin of theentrance, and forming an angle or `corner to receive the elastic cushion-stripI P l?, attached to the margin, so that when the door is shut the crevice will be airtight. The arrowsshow the direction of the aircurrent's.

suitable non-heat-conducting lining surrounding an ice-chamber, the dead-air chambers having no communication with the icechambers, or with the ventilators thereof or with each other, of an external weather -casing open below and separated from the Wall b y a continuous,,air-space, and united at the top to form a roof with a ventilator, Where such eX- ternal casing and roof are lined upon their inner surface with asbestus sheathing or other suitable non-heat-conducting sheet lining, and said air space is disconnected with direct airpassages from the ice-chamber, substantially as set forth. Y

In testimony whereof I hereunto set my handand seal this 30th day of January, A. 13.1883.. Y o.
