IMPRQVEID REFRIGERATOR IEOZRl `B'U'ILIDIN'Gi-S.

The' Schedule referred to invthese Lettera Patentl and making part of the same.

To all whom, it may concern Be it known that I, J ORN J. SOHILLINGER, of` -the city, county,'and State of New York, have invented a new and useful Improvement in Refligerator-Buildings;- and I do hereby declarethe following to be a full, clear, and exact description of; the same, which will enable those skilled in the art to make and use the same, referencey being had to the accompanyingv drawing, forming part of vthis specication, in which ldrawing-4 Figure l represents a vertical section of lthis invention. 1

Figure 2 is a horizontal section of the same, the" -line :IJ-w, iig. 1, indicating the plane of section.

Similar letters indicate corresponding parts.

This invention relates to a `refrigerator-building or ice-house, the ice-chamber of which is surrounded by a cold-air space, provided with suitable duets and valves leading-to the adjoining provision-chambers, in such a. manner, that when the ducts are closed, the cold-air space ,being filled with a very Abad conductor of heat, preservesthe ice in the ice-chamber against thee'xternal iniiuence, and, if the ducts are opened, a circulation of cold air Vtakes place from 'the cold-air space through the adjoining provision-chambers.

The bottom of the icefchamber is raised in one lor more points, so that the ice is kept as much as possble free from contact with the water resulting from the molten ice,

The water resulting from the condensation of the moisture in the air coming in contact with the exterior surface of the ice-chamber, is collected in agntter under the bottoni of the ice-chamber, and thence carried oi by a suitable pipe, and the interior of the roof is covered,with sheet-metal, and it inclines from one or more points down toward a gutter, which serves to collect the water resulting from the condensation of the moist or foul air in the interior of the ice-chamber.

The external walls of the building are rendered airtight by a covering of paper and sheet-metal combined.

The letter A designates the outside walls'of my re'igerator-building, which are covered on their inner surfaces with a layer, a, of paper, and a second layer, b, of sheet-metal, so that, by the paper, all the crevicesi are covered, and the walls are rendered comparatively air-tight, and, by the sheet-metal lining, the paper is protected against abrasion, or injury from other causes. In practice, the walls are made hollow, and filled with sawdust or other suitable material.

' The central space of my building is occupied by the ice-chamber B, which is constructed of slats, and the .side walls of which are covered, on the inside or outside, witliplain or corrugated sheet-metal.

The bottom of my ice-chamber is raised atone or more points, e, and it is cov-ered on the outside with sheet-metal, so that thev water resulting from the molten ice will run down toward the edges and be kept 'as much as possible from coming in contact with the ice in the chamber, andLfurthermorc, the coolingfsurface of the bottom is thereby increased, and the ice,

as it melts away, becomes a compact mass, whereby a great savingl in ice is effected. I t desired, the bottom may be made in sections, so that it can be easily handled.

The'root' d, of my ice-chamber, conforms in its shape to the bottom, and it is lined on.its inside with sheetmetal plates, which terminate overa gutter, e, so that the waterresnlting from the condensation of the foul or moist air in the ice-chamber will lcollect in said gutter, and be prevented from dripping down upon the ice in the ice-chamber. l

A similar gutter, f, is also' applied under the bottom of the ice-chamber, so that the watenresulting `from the condensation of the moisture ofthe air coming in contact with the-external surface of said bottom, will be collected in the gutter, and' the space below the ice-chamber will be kept dry. The water which collects in the gutters e f is carried oi by means of a pipe, g, whichl may pass down through one of the pillars 711,'-asshowh in iig. l of the drawing. l

The sides of the ice-chambers B are Haring ontward, so that between them and the walls t, of the room enclosing the ice-chamber, a triangular air-space, j, is formed,`which communicates with the adjoining provision-chambers G D by means of ducts k, provided with sutable valves, and with the vault E below, by means of ducts l, which can also be opened or closed by suitable valves.

It' these air-ducts are open, a circulation of cold air takes place from the airspace j, through the vault and the provision-chambers, as indicated by the arrows 'in iig. 1; but if the ducts It and'l are closed, the air in the cold-air space j, being a bad conductor of heat, preserves the ice in the ice-.chamber against the influence of the external atmosphere. n In this case the met-al plates covering the bottom of the ice-chamber form the only cooling-snrface, which, being in contact with the air in thevault E,

serves to keep the temperature in saidvault down toy The 'space above the roofzof thexice-chamberis l filled with sawdust, or other suitableymaterial, and a suitable opening or hatchway in said roof serves to introduce the ice.

The circulation ofthe cold air through thepro vision-chambers C is facilitated by means of pipes ln, which compel the cold air to pass through the entire space of l said chambers before it is allowed to return to the cold-air space j. I

By this arrangement, I am' enabled to produce a re'igerator-building which is particularly valuable for brewers and provision-dealers.7 and in which the ice is used with the greatest possible economy, p l

What I claim as new, and desire to secure by'Let'- ters Patent, is-

1. .The air-space jin combination with the ice chamber B, air-ducts k l, pipes n; vault E, and provision-chambers C O, all arranged, constructed, and operated as set forth.

2. The employment of layers a a, of paper, on the Walls, when used.v iu connection with a layer, b, of sheetiron or other metal, to prevent injury to the paper, as

set forth.
