DIVISION A.

To all whom it may concern:y

Be it known that I, EDWIN I). BRAINARI), of the city and county of Albany and State of New York, have invented a new and useful Improvement" in Apparatus for Desiccating and Refrigerating Purposes, to be used for preserving animal andyegetable substances, and for brewing and other purposes.

This apparatus is fuseful in the construction of ice-chambers, rerigerating-chambers, domestic refrigerators, fermenting-chambers, storerooms for preserving, railroad-cars and other vehicles used for transportation, and for all rooms and boxes for storing, transporting, and keeping sound and fresh-fruits, vegetables, meats, butter, lard, and other similar materials. Such apparatus is also useful in the construction of roomsl used in breweries for ferment-ing and storing ale, beer, and for storing ic'e, and for all purposes where a low even temperature and dry atmosphere is required. 'When applied to the ice-chamber it produces adry atmosphere and prevents all backdrip; and when th'e ice-chamber is completely insulated from the influence of the surrounding or outside atmosphere it maintains in the chamber a dry atmosphere at the temperature of 340, which atmosphere is always fIt for use in other chambers, for the purpose of moderating the temperature of such other chambers. When applied to fermenting-chambers the heat and moisture arising from the fermenting liquors are arrested by condensation upon the inclined surfaces of the metallic ceiling, and are conveyed from the chamber by the drip-gutters and pipes arranged for that purpose, so as to keep the4 chamber dry and sweet. Should the heat generated by fermentation become too great for safety in the fermenting-chamber, the dry cold air of the ice-chamber, standing at. 340 Fahrenheit, can be admitted at pleasure to regulate the temperature to any desired degree above 340. My

` improved apparatus consists in applying corrugated or inclined metallic surfaces for ceilings of rooms or chambers, so combined with drip-gutters as to condense upon such inclined surfaces the moisture contained in the atmosphere in such chambers or rooms, which moisture, so condensed, drips into the gutters, and is thence conveyed by gutters and pipes out of the chamber.

In the accompanying drawing, Figure 1 represents a room or rooms, to which my corrugated or inclined metallic surfaces are applied as a ceiling. In such figure the metallic corrugations or inclines are seen at a a a a a, the corresponding gutters are seen at c c c c c. In said figure No. l represents the ice-chamber. the storage or fermenting-ehamber. No. 3 represents the same as No. 2, showing the manner in which the corrugations are attached to the beams and connected with and covered by the caps at h h.

-The particular manner of attaching the corrugated iron ceiling to the timbers and the manner of makingthe union of the caps with these corrugations are represented in Fig. 4 of the accompan ying drawing. A

The manner in which my improvement operates to produce the desired effect is as follows: The warm air in the room or chamber rises in right lines to the ceiling and comes in contact with these inclined metallic, surfaces a. a a, &c., upon which the moisture contained in the atmosphere is condensed, and from which it drips into the gutters c c c c, Src., and is by them discharged into crossgutters and thence into pipes and conveyed from the ch amber. lIn this manner, whenever from any cause the temperature in the chamber is increased, these ascending currents take place, and the moisture contained in these cury rents is deposited upon these metallic inclines and disposed of asr above described.

Reference is hereby given to the accompanying drawing containing Figs. l, 2, 3, and 4, in which figures the same letters refer to the same parts of my apparatus.

Having thus fully explained the nature Aand operation of my said improvement, I desire to secure by Letters Patent the following claims:

1. The condensing and refrigera'ting inclined metallic surfaces combined with drip-gutters, arranged substantially inthe manner and for the purposes above described.

2. The method of forming the condensing inclines by uniting the sides to a cap with closed double seams, substantially as described.
