UNITED STATES PATENT OFFICE.
GEORGE W. DEITZLER, OF SAN FRANCISCO, CALIFORNIA.
REFRIGERAT ING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 247,022, dated September 13, 1881,
Application filed April 22, 1881. (Model.)
To all 'whom it may concern:
Be it known that I, GEORGE W. DEITZLER, of San Francisco, in the county of San Francisco and State ofGalifornia, have invented a new and useful Improvement in Filtering, Cooling, and Refrigerating Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to the cooling of animal and vegetable substance by the evaporation of water contained in porous vessels, such vessels being exposed to a draft of air, by which such evaporation is caused; and its object is to supply a simple and cheap construction of apparatus for this purpose.
My invention consists, first, in combining with a doublewalled refrigerator, the outer wall constructed of porous material forming a water-space, a coil of pipe passing through such water-space; also, in the peculiar construclion of cooler and, further, in combining with such cooler a novel construction of filter, all as fully hereinafter explained.
In the drawings hereunto attached and forming part of this specification, Figure 1 is a central longitudinal section of the entire apparatus; Fig. 2, a top view of the cooler with the cover removed, and Fig. 3 a plan view of the refrigerator.
My refrigerator is composed of two walls,A A, preferably of circular form, the outer wall, A, being constructed of term cotta or' other suitable porous material. In such outer wall is a door, B, which may be made of either wood or metal, lined with felt, so as to be perfectly air-tight when closed.
0 is an annular water-chamber between the walls of the refrigerator, which extends entirely around the refrigerator, except in front, where the door is placed. A cock, I), is provided, by which water may be drawn off from the chamber 0. D is a coil of pipe, placed in the annular water-chamber, near the top thereof, passing through the same and through the outer wall, near the bottom thereof, as shown.
The provision chamber E is formed by the interior wall, A, and is provided with racks,
upon which shelves may be supported to contain the articles to be preserved. It is evident that if the chamber 0 be filled with water and the refrigerating-vessel be exposed to the air, the water which percolates through the porous material of which the vessel is composed will be rapidly evaporated by the outside air, and in consequence thereof the temperature of the waterin the annular chamber will be materially reduced, and this reduction will also affect the temperature of all articles contained within the interior provision-chamber. It is also evident that bcer or any other liquid will be cooled in its'passage through the coil of pipes in the water space in such chamber.
The interior wall maybe made of terra-cotta or of metal. In case it is made of porous material, the interior face of the provision-chamber should be glazed or otherwise made watertight to prevent the water in the chamber 0 from percolating through.
In connection with this refrigerator I use a cooler, F, of which a top view is shown in Fig. 2. This cooler is likewise composed of a porous material, preferably of terra-cotta, and in practice is usually placed on the top of the re frigerator and secured thereto in any suitable manner.
The cooler is divided into two parts by a horizontal partition, G, and a circular chamber, H, extends from the partition G to near the floor of the cooler, leaving an annular water-space, I, surrounding the said chamber. Above the partition the space left forms areservoir, J, which receives the water to be filtered and cooled;
.In order that the water that is cooled may be purified and rendered fit for use, I combine with the cooler a peculiar construction (represented at K) of filter, which is now described.
The filter or vessel in which the filtering material is placed is composed of a cylinder of slightly less diameter than that of the chamber H, into which it is placed. At the lower end of the filter is a perforated diaphragm, d,
and near its upper end is a circular flange, e,
which is also perforated, as shown. Thelength of the cylinder is such that when it is supported upon the partition G by the flange e the diaphragm at will be a short distance above the floor of the cooler, thus leaving a space around and below the filter for the passage of water.
The pipe f is fitted in a cork through the top of the filter, and enters an opening, g, in the partition G, making water-tightjoints.
The operation of the filtering device will be readily understood. The reservoir is filled with Water, which is then rendered cool by the process of evaporation before described. The water passes through the perforations in the flange e and into the space surrounding the filter, whence it passes up into such filter through the diaphragm d, and the impurities contained therein are deposited on the horizontal partition G and on the bottom of the chamber H, whence they may be removed whenever it is desired to clean the apparatus. The water, passing through the filtering medium hereinafter described, is led through the pipe f and into the annular chamber below the partition, which is provided with a cock for drawing off the water as required.
When the cooler is used in connection with the refrigerator a passage, 0, is provided from the chamber 1 into the water-space O in the refrigerator, which may thus be supplied with water already cooled and purified.
Any filtering medium may be used that may be desired, though I prefer to employ a particular kind of black sand composed, principally, of magnetic oxide of iron, which is fully described and claimed in an application for Letters Patent about to be made by me.
It will be understood that the filtering material is placed in the filter K, and that the water passes up through it, instead of down from above, as is commonly the case in filtering apparatus. These devices may be use d separately, in which case the passage 0 from the cooler to the water-chamber of the refrigerator would be closed and the refrigerator provided with a top, having its inside surface made water tight to prevent the passage of water. In this case a pipe or other suitable device would be necessary to supply water to the space 0. I have found, however, that the best results are produced by using both devices in combination, and it is in this manner that I prefer to use them.
In practice the entire device is preferably inclosed in acasing or jacket, and any suitable means, such as a furnace or an exhaustfan, is employed for creating a draft through said jacket and over the surface of the porous vessel, as described and claimed in my other patents.
As thus constructed, my devices form a cheap, convenient, and efficient filter, refrigerator,and cooler, by which not only perishable articles may be preserved, the water filtered and cooled, but beer and other liquids may also be cooled by passing them through the cooler, as before described.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination of an outer wall of porous material and an inner non-porous wall, forming a water-space, with a coil of pipe, substantially as and for the purposes set forth.
2. The described cooler, having a single wall of porous material and a reservoir, J, to supply water tothe outer surface, a filter, K, and a surrounding chamber, H, to receive the cooled and purified water, substantially as described.
3. The combination, with the cooler having the partition G and chamber H, of the filter K, provided with perforated flange e and diaphragm d, substantially as described and shown.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
GEORGE W. DEITZLER.
