DEVlCE FOR COOLING STORAGE-CHAMBERS.

SPECIFICATION forming part of Letters Patent No. 346,807, dated August 3, 1886.

` Application filed May 27, 1886. Serial No. 203,419. (No model.) l

To aZZ whom it may concern:

Be it known that I, ANTHONY F. CRAMER, of Detroit, in the county o f Vayne and State of Michigan, have invented new and useful Improvements in Devices for Cooling Storage- Chambers; and I do hereby declare that the vfollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this Speciiication.

This invention relates to certain new and useful improvements in means for cooling beer- Vaults and other rooms in which it is desired to preserve alow temperature. Hitherto this has been done in various ways, in which the cooling mixture has been carried through pipes, but this has been found to be objectionable, as the cooling mixture flowing through them corrodes the pipes, and is apt to clog them up by deposits, which can only be cleared out by taking down the pipes for the purpose.

The object of this invention is to provide means for reducing and securing a low temperature without the necessity7 ofthe employ ment of pipes; and the invention consists in the peculiar construction and combinations of the necessary parts, as more fully hereinafter described.

Figure lis a sectional elevation, showing my improvement as applied to keeping a low temperature in a beer-vault. Fig. 2 is a sec tional cross-elevation of the same.

In the drawings, A represents a refrigerator or box, having a perforated false bottom, a, hereby forming a well, b, in the bottom of the B is apump, having a suction-pipe, O, communicating with such Well, andan outlet-pipe, D, through which the pump discharges, and which is provided with one or more faucets, c.

E are shallow open pans supported by brackets F from the ceiling of the vault G, or in any other preferable or suitable manner. These pans are arranged above and below eachother, and they are each provided with an overflowpipe, d, so arranged as to allow the pans to remain nearly full, and overflow from the top one into those below it successively. The overflow of the lower pan connects with a pipe, H, leading into the well b.

I is an overow pipe leading from the refrigerating-box to a sewer, e, or to any other desired point.

J is a chute, through which the refrigerating materialcan be fed to the refrigerating-box from the floor above when required.

In practice the refrigerating-box is located on the floor of the chamber to be cooled and filled with ice and salt, lthe melting of which fills the well in the bottom, whence it is Withdrawn by the action of the pump, and dis` charged into the upper pan, and thence it overflows into the paus below and finally into the well again, the current in the well being created by the suction preventing the salt in the mixture from settling in the well, when, if such settling is allowed, it would crystallize and form a solid mass.

I am aware of the Patents Nos. 194,414 and 341,906, and make no claim to the construe tion shown therein as forming part of my invention.

What I claim as my invention is- The refrigerating structure described, cousisting of the box A, having perforated false bottom, a, forming a well, b, below the same, pump b, suction-pipe O, passing through said box and communicating with said well, outlet-pipe D to said pump, open pans E above said box, one above the other, and provided with overliow-pipes d, and the pipe H passing through the box A, and connecting said well with the lowest of said pans, and the inclined chut-e J, for conducting the refrigerating material into the box A, all arranged for joint operation, as set forth.
