IMPROVEMENT IN COOLING-BUILDINGS.

4 Specification forming part of Letters Patent No. 108,707, dated October 25, 1870.

To all whom it may concern:

Beit known that I, THEonoRE KRAUscI-I, of the city, county, and State ot' New York, have invented a new and Improved Refrigerator-Building; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawing, forming part of this specification, in which drawin g Figure l represents a vertical section of this invention. Fig. 2 is a horizontal section of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of an air-space surrounding the icecha1nber of a refrigerator-building, and communicating with an air`trunk through which the cold air descends, and from which the air can be exhausted by artificial means in such a manner that the top as well as the sides of the icechamber will act as a cooling-surface, and that by keeping up a circulation of air over and around the ice-chamber the ice is saved, and the condensation of moisture on the inner surface of the top of the ice-chamber is prevented.

The circulation of air through the refrigerator-building is increased by the suction produced by a steam-jet, which is situated in a suction-pipe extending down through the airtrunk, and which communicates through suitvable apertures at different heights with the air-trunk, and with the several stories of the building, so that the circulation ot air through the building can be controlled without 'dithculty.

The interior ofthe ref ri gerator-buildin g com municates with the external air through a pipe, which is exposed to the cooling effect of the ice-water, and situated either directly below the icechamber or in the lower part of the icehouse. The air-space surrounding the icechamber also connects with side channels, so that a natural circulation of cold air can be effected through the various stories of the buildin fr.

In the drawing, the letter A designates a refrigcrator-building, which is divided ofi' by two (more or less) doors, c b, into three (more or less) stories, c d e. On the top floor is placed the ice-chamber B, which is surrounded b an air-s ace and the bottom of which is elevated above the top iloor, a., so as to leave a trough, g, in which the ice-water collects.

Through the ice-chamber, and through all the iioors of the building, extends the airtrunk C, which rests on the ground iioor, and may be made to serve as a pillar to support the upper iioors, b and c. In the sides of this trunk, and on a level with the upper surface ot' the top floor, a, is a series of small holes, h, through which the ice-water from the trough (1 passes into thel air-trunk, running down on its inner sides until it reaches the bottom tank, D, which is provided with an overow-pipc, h.

In the sides ot' the air-trunk are openings t', one or more in each story of the building, and the top of said air-trunk is provided with a cover, j, which can be opened or closed. When this cover is open the cold air from the air-space f descends through the trunk, where it comes in contact with the ice-water trickling down on its sides, so that it is still further cooled off, and by opening one or more of the openings i the cold air is discharged into either one or more of the stories of the building.

From the ice-water trough g extend short pipes p through the top floor, a., and suitable slides K* serve to open or close these pipes. When the pipes are open the cold air from the trough g descends in the story below the tloor a. rlhe air-space f also connects with vertical air-trunks L k', which are `provided with apertures l l', the apertures Z in the trunk k being close above the several floors, while the apertures l' in the trunk la are close under the several floors. v.lhe cold air from the air-spacef descends through the trunk k, discharges in either of the stories of the building, and rises through the trunk k', and by these means a continuous circulation of air takes place through the building and through the airspace f, and the ice-chamber is thereby kept comparatively cool, and the condensation ot' moisture on the top of the ice-chamber is prevented. The vertical air-trunks may also be used in combination with the central airtrunk.

Through the trough g extends a horizontal pipe, m, which communicates with the external air, and which is exposed to the cooling` eftectof the ice-water in the trough. In this T Ferron pipe are openings u, and if the pipes p are open the external air passes in through the pipe m, where it is cooled by the action of the ice-water, and then it passes down through the pipes p. y

ln order to create an artificial circulation of air through my building, I pass a pipe, E, down through the center of the air-trunk C, and out through the top of the building. In the Vupper part of this pipe I introduce a steam-jet, F, and its lower part is provided at certain intervals with openings o ol 02, leading into the air-trunk, or with cross-pipes p, extending through the sides of the air-trunk, and communicating with 'the space or spaces surrounding said air-trunk.

If the openings i in the sides of the trunk are opened and the steam-jet is started, the air from the top part of each story is sucked into the pipe E and driven out by the steam-jet, a fresh supply ot' air being drawn in through the horizontal pipe m or otherwise.

I use a steam-jet for the purpose of produc ing the artificial circulation in my buildin g, because such steam-jet requires not much outlay for machinery and no attention, and if it is connected with a steam-generator, which is on hand in every brewery or other place where my refrigerator-builc'ling is to be used, it (the steamjet) can be started or stopped simply by turning a stop-cock.

Having thus described my'invention, what I claim as new, and desire to secure by Letters Patent, is

1. The pipe E, inclosed within the air-trunk C, and communicating with the latter as described, with the air-space f, surrounding the ice-chamber B, said airspace and icebox being arranged in the top part of the building, and operating in connection with the lower rooms, substantially as and for the purpose described. i

2. The vertical air-trunks 7c 7c', central pipe. E, inclosed within the air-trunk (l, in colnbination with the air-space f, surrounding the ice-chamber B, and operating with reference to the lower rooms, as herein shown and described.

3. In combination7 the air-spacef, surrounding the icechan1ber B, arranged in the top of a building, and the central pipe, E, of a steamjet, applied and operating as herein set forth.

4. The pipe m, with openings fn., in combination with the stand-pipe p of the waste- Water chamber, for the purpose of cooling the incoming currents of air.
