APPARATUS FOR FILTERING AND REFRIGERATING WATER.

SPECIFICATION forming part of Letters Patent No. 277,931, dated May 22, 1883.

Application filed August 29, 1882. v (No model.)

To all whom it may concern Be it known that I, SAMUEL F. REYNOLDS, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, haveinvented certain new and useful Improvements in Apparatus for Filtering and Refrigerating \Vater; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others to skilled in the art to whiclrit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. :5 This invention relates to an improved ap- -paratus for filtering and refrigerating water for domestic and other purposes; and it consists in a method of cooling water by bringing it in contact with a chamber containing cooled air or other refrigerating material; and also in certain peculiarities in the construction, arrangemeut,, and combination of the various parts of a water filtering and cooling device, as hereinafter more fully described and claimed. In the annexed drawings, illustrating my invention, Figure l is asectional side elevation ofa water cooling and filtering apparatus, showing one form of applying my invention. Fig. 2 represents a side and an end view of 0 my improved filter with perforated plates or screws.

Like letters are used to designate like parts. Referring to the drawings, A denotes a power-fan that is connected with a coil, B, in- 3 5 closed in a tank or ice-receptacle, G. The upper end or branch, B, of the coil B may be extended vertically or in any desired direction for the purpose of conveying cooled air'to the chamber D of a water-cooler, or to water 0 tanks or refrigerators in various parts of the same building or in different buildings. As

' represented in the drawings, the cooled air chamber D is connected with the cold-air coil B by'meaus ofa pipe, B extending from the 5 pipeBY to the cap E of the cold-air chamber. This coldair chamber is preferably composed of cast-iron, and has the form of a bowl. It

is suspended in the water tank or chamber F in such a way as to form the upper part or 0 wall of the same, and is itself provided with a concavo-convex cap or cover, E, as before described. The cold-air chamber D and water chamber F are inclosed in ajacket or casing, Gr, constructed of any desired material and in any suitable form. This casingis designed to be supported in any appropriate manner, aud is provided with a faucet, H, that communicates with the water-chamber F. The lower part of the cold-air chamber or how] D is provided internally with an annular projection. to, through which is passed the upper end of a vertical pipe, I, that passes down through the water-receptacle F and filter K. This unnular projection is provided at; the top with an annular groove or recess for the reception of packing I), and a nut, c, is attached to the upper part of the pipe I for the purpose of securing it in position. The filter K is connected by screw-threads or otherwise with an opening in the bottom of the water-tank and its inclosingjacket, and is provided with a tlange or collar, (1, that lits beneath the edge of the opening in the jacket, the upper part of the collar, which may be either fixed or movable, being recessed for the reception of suitable packing, 0, as shown in Fig. 1. The upper part of the filter-tube Kis provided with a "finely-perforated plate or screen,f, and similar screens 9 71, are also arranged at intervals within the filter. These screens are also perforated centrally for the passage of the waste-pipe I, which also passes through a removable cap, '5, at the lower end of the filter-tube, and is there secured by a nut, 70. The cap i is provided with a nozzle and mud-valve,m. A feed-pipe, L, is arranged to enter the filter at a point below the fixed screen h, and is provided with a valve, 12, for governing the supply of water. The screen It is fixed within the filter K at a suitable point to allow an ample space beneath for the deposit of sediment, and the feed-pipe L is arranged to enter the filter at such a height that it cannot possibly disturb the sediment deposited in the lower end of the filter. It will thus be seen that after the sediment is separated it the force of the incoming water; but will re main in the bottom of the filter until it is re moved through the mud-valve m, or by detaching and cleansing the cap Above the screen h are placed layers of gravel, with an intermediate layer of charcoal,

will not again be carried up into the filter by or any other suitable filtering material may be used, the whole being covered by a movable orloose-fitting screen, g, above which is placed a quantity of sand or other filtering substance. The plate or screen 9, being placed loosely within the filter between the sand and gravel, will rise under the pressure of the upward flow of water, and thus pack the sand tightly.

In arranging this apparatus within a building, I prefer to place the coil B and ice-tank .O in the basement or cellar; or the coil may be placed in an ice-house or other suitable situation incontact with refrigerating material. The coil B is connected at one end with the fan A, while its 'other'end is extended to the place to be cooled. The coil may be surrounded with ice alone or with ice and water. The air, forced by the fan and cooled by its proximity to the refrigerating material, is thus readily conducted to any desired apartment or to the water-tanks or coolers located therein.

It is obvious that the air-conducting pipes may be covered in any suitable manner, or may be laid in the ground or be embedded in the walls of a building, for the purpose of protectin g them from the access of heat.

It will be seen that when cold air is introduced to the chamber or bowl D, which is in contact with the water contained in the chamher I the water is thus readily cooled without being brought directly in contact with ice, thus avoiding the ordinary necessity of conveyiug ice from one apartment or building to another.

If desired, the cap E and air-conducting pipe B may be disconnected from the jacket or casing G, and the bowl D and water'chamber F be used alone or simply in connection with the filtering devices above described. In this case ice will be placed in the bowl immediately above the water-chamber. The pipe I serves as an exit for air when the entire apparatus is used, and for melted ice when ice is placed in the bowl D. It will be observed that the form of the bowl or chamber D is such that the ice or the cold air will chill the material of which the bowl is composed at the most effective point-that is to say, at the point where water from the filter enters the water-chamber-and it also enables the bowl 'to present a larger cold surface all the way up to the faucet than would be practical if its form were'rectangular instead of being as shown.

Bypassing the water-supply upward through the filter and arranging the feed-pipe and filtering material in the manner described, it will be seen that the water conducted to the cooling-chamber will be filtered in the most effective manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the jacket Gr, waterchamber F, faucet H, refrigerating bowl or chamber D, suspended in the water-chamber, and having cap E and internal annular projection a, the filter K, having feed-pipe L, perforated screensfg h, and cap 2', the'waste-pipe I, nuts 0 7r, collar (1, and packing b a, substantially as described.

2. The combination of the fan A, refrigerating-tank G, coil B, inclosed in said tank, the jacket or casing G, watenchamber F, refrigerating bowl or chamber D, suspended in the water-chamber, the concavo-convex cap E, pipe B connecting the coil B and chamberD, the faucet H and filter K, communicatingwith the waterchamber, the waste-pipe I, filterscreensfg h, cap 2', having mud-valve m, and the feed-pipe L,eutering the filter, all substantially. as shown and described.

3. The method of filtering and cooling water, consisting in conveying the water vertically through a tube containing filtering material, whereby the sedimentis separated and deposited in the bottom ofsaid filter, and then bringing the water in contact with a chamber con-. taining cold air, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
