FROST-GUARD FOR REFRIGERATOR-BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 679,526, dated July 30, 1901.

Application led February 28I 1901. Serial No. 49,222. (No model.)

To (t-ZZ whom, t 1n/tty concern.'

Bc it known that we, VILLIAM B. CARNAY, LOUIS Scnwasaand CHARLES ScHvvARz,eiti zens of the United States of America, residing at Ballston Spa, in the county of Saratoga and State of New York,have invented certain new and useful Improvements in Frost-Guards for Refrigerator-Buildiugs, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l representsa perspective view, Fig. 2 a sectional View, and Fig. 3 a vertical sectional view, of our improved guard or curtain.

A serious need has been felt in connection with refrigerator-buildings for an eflicient frost-guard for guarding or screening the goods in the storage-rooms adjacent to the refrigerating-pipes on the side walls of the storage-rooms, and the lack of means to till this need frequently occasions loss of either goods or valuable storage-space; and it is the object of this invention to provide a simple device which will serve as an efiicient guard or screen to prevent frost collecting on the goods stored adjacent to the cooling-pipes, and thus prevent the cold penetrating the goods sufeiently to destroy or damage them, thereby permitting the utilization of the full capacity of said storage-rooms, as more fully hereinafter set forth.

The preferred form ofthe guard is shown in the accompanying drawings, in which the outer face (the face farthest from the cooling pipes) of the guard is constructed of a series of closely-joined spruce boards d of a suitable thickness and secured together by a layer l) of insulating-paper and strips ot' wood c, the paper lying directly against and covering the entire inner faces of the boards and the strips being secured against the paper around the edges thereof and at suitable intervalssay eighteen inches apart. Upon the strips c is placed another layer d of insulating-paper, which covers the entire inner face of the device and is fastened by another series of wooden strips e, nailed to the strips c. Suitable means, such as hooks and eyes, is provided for detachably suspending the guard from the ceiling of the storage-room, preferably about ten inches from the wall holding the cooling-pipe, and to maintain the suspended guard approximately parallel with said wall it is provided at its lower end with inward-extending braces or legs f, which are adapted to rest against said wall, as shown.

The completed guard or curtain is coated with a solution of ealcium-chlorid brine, and this coating is desirably renewed each season.

lt will be observed that the wall of closelyjoined board, the layer of insulating-paper, and the dead-air chamber formed between the paper layers form an effective barrier in preventing the frost penetrating the goods adjacent to the pipes, thus permitting goods that would be injured by being frozen to be stored in these rooms close up to the frost-guard, thereby utilizing to its fullest extent the capacity of these rooms. The brine coating serves to prevent frost gathering upon the guard and at the same time does not become tainted or emit objectionable odors.

It will be observed that the guard is addi= tionally advantageous in that it assists in promoting circulation of cold air, the warmer air entering over the top of the guard and falling through the space between the guard and the wall as its temperature is reduced by contact with the cooling-pipes. To insure this circulation, it is evident that there must be a space for the entrance of the warmer air between the top of the guard and the ceiling of the room, as shown.

Having thus fully described our invention, what we claim is l. A non-conducting frost-guard for the purpose Set forth provided with means for detachably suspending it from the ceiling and at its lower end with inward-extending arms for maintaining it approximately parallel with the wall holding the pipes to be guarded against.

2. In combination with a cold-storage room, the side wall of which is provided with refrigerating-pipes and whose ceiling is provided with the upper members of hook-and-eye connections, of a non-conducting frost guard or curtain provided at its upper` edge with the lower members of said hook-and-eye connections and at its lower end with means for maintaining it approximately parallel with the wall carrying said pipes, the upper edge IOO of said frost-guard or curtain lying at rdis.- In testimonyfwhereof We hereunto affix our tance below the eeilingland its loweredge ter signatures, in the presence of two Witnesses, minating short, of the Hoor. this 23d day of February, 1901.

3. A frost-guard for the purpose set forth,

5 consisting of asoiid wooden outer face, a layer of insulating-paperon the inner sidevthoreof, J'

a series of separated strips, another layer. of" CHARLES SCIUVARZ' insulating-paper on said strips, forming a f fitnessesz dead-air cham bemand another series of strips, i LIZZIE SWEENY,

io the whole being fastened together. JOHN D. VAIT.
