GEORGEy IV. SMITH, OF MOUNT VERNON, ASSIGNOR OF ONE-HALF TO JOHN M. SHINN, OF VELI-IORM MANOR, NEV YORK.
AIR-COOLING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 456,444. dated July 21, 1891.
I Application filed November 24, 1890. Serial No. 372,435. (No model.)
To @ZZ whom it may concern: struction or the provision of a coldstorage Be it known that I, GEORGE YV. SMITH, of room such as has been described.
MounnVernon, in the county of Westchester IVithin the chamber A a preferably rectanand State of New York, have invented a new guiar metallic box B is located, which has a 5 and Improved Apparatus for Refrigeration, surrounding wall C provided on all sides eX- 55 of which the following is a full, clear, and except the cover D, sufficient supports, as at a,
act description. being furnished to sustain the box above the Thisinvention relates to animproved means bottom wall of the outer enveloping wall C,

o provide an apparatus whereby the interior the cover D being adapted to seal the box. 6o air of a sealed chamber used for cold storage IVithin the ice-boXB a central metallic air- Inay be maintained at a low temperature for cooling compartment E is placed, so that the the preservation of articles of food and drink. ice F when in place within the box B will A further object is to provide a cold-air completely surround the sides of the comr 5 producing apparatus which will be economipartment and lie against its thin walls. A 65 cal in consumption of refrigerating material tubular airpassage G is extended from the and be reliable in operation. interior of the air-compartment E to and To these ends my invention consists in the through the vertical side wall thereof and of construction and combination of parts in an the ice-box B', as at c d, whereby a conduit 2o apparatus which will be hereinafter described for the transmission of airis afforded between 7o and claimed. the air-space b and air-holding central com- Reference is to be had to the accompanying partment mentioned. Through another wall drawings, formingapart of this specification, of the central air-cooling compartment E a in which similar letters of reference indicate second airconducting pipe H is inserted,

4o The chamber A may be of any desired ca- The fan-blower I is adapted for service by 90 pacity for uthe cold storage of articles of food connection of its fan-pulley g with any source "of various kinds or malt liquors, and is prefof power by a belt, (not shown,) andis of a erably of rectangular form, having an insulatype which is adapted to receive its supply of tion-B secured upon all its walls and a sheetair through an aperture in one side, the other 45 metal lining Cwithin, that should be non-con side being closed, excepting an orifice cen- 95 rosive, such as zinc or tin plate; and said trally formed for the introduction of the fanchamber should be provided with means of shaft 7L. access to its interior, which may be sealed, Upon the open side of the fan-blower I an as is usual in such chambers, there being no air-supply box I is secured, that covers the 5o claim made for novelty in the form of conaperture in the side wall of the blower-easloo ing, as represented in Fig. l, and from said air-supply box an exhaust-air pipe M is extended to an upper point on the side Wall of the storage-chain ber A, through which the exhaust-air pipe is introduced, as at t', so as to permit the revoluble movement of the blower I to draw air from the upper portion of the storage-chamber.
In use the box B', having been iilled with ice and the articles to be refrigerated placed in the storage-chamber A, and said chamber sealed to prevent any introduction of air from without, a revolution of the fan-blower I will draw air from the storage-chamber, as indicated by the arrows l, which Will be forced back through the air-pipe J' into the airspace b, and thence into the central air-compartment E, from which it Will issue after it has come in contact with the cold Walls of said compartment. (Shown by arrows.) The continuous circulation ot' the air contained in the storage-chamber through the air-passages around and in the ice-boli B' speedily reduces its temperatureA to nearly a freezingpoint, which may be maintained with a small percentage of ice consumption if the storagechamber A is not left open to introduce a great amount of heated external air. The air in the storage-chamber, as it is warmed by contact with fresh articles placed within it, rises to the top and is Withdrawn by the exhaustion of the fan-blower, and after eirculating for a short time, as has been described, Will deposit nearly all the moisture it contains upon the metallic walls of the icebox B' and air-compartment E, so that the air f is rendered dry and preservative, as well as cold, thus conducing to the preservation of perishable articles of food or drinkV placed within the storage-chamber.
I'Iaving thus described my invention, I claim as new and desire to secure by Letters Patent 1. A refrigerating apparatus consisting in the storage-chamber, an ice-box therein provided with a central chamber E and an outer surrounding Wall C', spaced to form the passageb, a pipe or passage G, connecting the chamber E and space l), a pipe or passage H, connecting the chamber E with the interior of the storage-chamber, and a blower for exhausting air from the storage-chamber and returning it to the space b, substantially as set forth.
2. A refrigerating apparatus consisting in the storage-chamber A, an ice-box B Within the said chamber and having a central chamber E, a Wall C', surrounding the ice-box and spaced from the sides, ends, and bottom of the box to form the air-space b, a cover I), closing the top of the box, the chamber, and the space l), a pipe or passage G, leading from the space b into the chamber E, a pipe H, connecting the chamber E With the interior of the storage-chamber, a pipe or passage J', leading from the exteriorof the storage-charnber into the space b, a pipe 1T, leading from the upper end of the storage-chamber outward, and a rotary blower or pump connected with the pipes i J and exhausting the air through the former and returning it through the latter pipe, substantially as set forth. 1
