IMPROVEMENT lN REFRIGERATING-CHAMBERS, SoC.

Specification forming part of Letters Patent No. 222, M14, dated December 2, 1879 5 application filed September 24, 1879.

. preserving vegetable, animal, and other substances, and forfermenting and other purposes, of which the following is a specification.

ln the construction of ice and refrigerating chambers itis common to employ metallic corrugations or inclines to form the ceiling of such chambers, Whether used for storing ice or other purposes, as refrigeration, requiring a low temperature and dry atmosphere to be used, for

condensing upon the inclined or corrugated under surfaces the moisture contained in the atmosphere and rising to such surfaces, and employing, in connection with such inclined surfaces, gutters or driptroughs to receive and conveyaway the drip from such ceilings and discharge it outside the chamber. These ceilings formed, however, of metallic corrugations or inclines are objectionable, serving as repositories for slime and the accumulation of foreign matter contained in the ice, which in time accumulate to such an extent to impair and impede seriously the refrigerating effect due the ice upon the refrigerating-cham ber.

To overcome these defects is the object of my invention, and at the same time produceadry atmosphere and low temperature in the ice and refrigerating-chamber.

The nature of my invention consists in forming the ioor of the ice-chamber, constituting also the ceiling of the retrigerating-chamber,

in sections, of galvanized iron or other metal, having inclined or curved sides, and sides terminating vertically, thereby forming passages which are Water-sealed by means of removable drip-troughs troughs, scribed. p

Referring to the annexed drawings, Figure l represents a perspective view. Fig. 2 repre` provided with condensingall as Will be hereinafter fully deand inclined ends b', terminating vertically,

as shown at c, thereby forming passages cl. C designates aremovable drip-trough, suspended 1n such a manner as to close the passage d,

formed by the vertical sides of the floor-sections, the object of which is to receive and collect the drip-Water from the melting ice, also the Water ot' condensation formed upon the under sides of the inclined plates of the floor, thereby forming, in combination with the vertical sides c, a Water-seal, thus preventing the circulation of air direct from the ice-chamber into the refrigeratingchamber, or the Warm air from the refrigerating-chamber entering' the ice-chamber. The trough also serves as a collector for foreign matter cntained in the ice and a receptacle for slime.A

c designates an overflow-pipe, connected to the trough C near its upper edge, for the pur-i pose Vof discharging the drip-Water into the trough D, from Which it is led to any suitable receptacle. j' designates a pipe connected to the lower part of the trough @,for the purpose of emptying the same of Water. E designates a gutter for conveying away the water of condensation formed upon the trough C, Which also empties into D.

From the above description it will `be observed that the door, being in sections and not secured to, butresting upon, the joists, and having seams only Where the ends of the sections meet, is easily removable for any needed repairs, Sco.

The manner in which m im rovemento erates to produce the desired effect is as follows: Ice having been placed or stored Within the ice-chamber and the removable troughs suspended in proper position, the drip-Water accumulates Within the trough, forming a `Waterseal with the door of the ice-chamber.

lt will also be observed that all foreign matter contained in the ice and carried down by the drip-Water accumulates within the driptrough, which, being removable, is easily and readily cleaned and replaced or another substituted in its place.

It will also be observed that by means of the passages d access may be had to the upper surfaces of the-floor for the purpose of removing slime or any foreign matter that may have accumulated thereon, and thereby restoring the cooling effects of the refrigeratin g material.
