WATER-COOLER.

SPECIFICATION forming part of Letters Patent No. 235,696, dated December 21, 1880.

ApplicationledOctober26,1880. (No model.) 4

To all 'whom tt may concern Be it known that I, THOMAS D. MowLns, a citizen ofthe United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Water-Coolers, and I do hereby declare the following to be a full, clear, and exact description or" the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in water-coolers for which Letters PatentNo. 224,7] 2 were granted me February l2, 1880, in which only a small quantity of water is kept on the ice and this supply automatically renewed as needed.

The objects of my improvements are, first, to provide a secure and easily-adjusted airtight cover for the icechamber; second, to draw off any surplus water made by the melting of the ice in the ice-chamber. I attain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1 is a plan of the cooler; Fig. 2, a vertical transverse sectional view of the same; Fig. 3, a view of the spigot as turned on for drawing oft water. Y

N is the chamber for the ice; K, lump of ice therein; M M, packing around the ice-chamber; L L, reservoir for the additional supply of water; F F, a movable cover, made on the principle of the diving-bell, and lit-ting snugly over the outside of the ice-chamber, and at the same time covering over the top of the supplytube B. This top reaches to the bottom of the reservoir L, and is held in position by the snugt; or, if necessary, any suitable fastent ing may be adjusted. H H are the walls of the icechamber5 A G, an ordinary bib-cock for drawing oi" water, of which A is the tube and 4Gr is the plug. The bearing` in the cock is made to extend some considerable distance up and around the plug, (see Fig. 3,) and the plug has a small opening therein, said opening beinga short distance above and running parallel with the water-way. Through the bearing, on both sides, is also a small opening', to correspon d with the hole in the plug, so that when the cock is turned to draw off water the opening through the plug G and the openings in the bearing are on a line with the tube DD, as shown by the dotted line in Fig. 3. I is the second waterway in the side of the cock, (not in the plug, that having one water-way only,) to which ,0n either side, are attached the tubes B and C; D D, an air-tube extending from the inside of the ice-chamber, above the water-line, to and connecting with the opening in the bearing ot' the plug G; E E, an air-tube extending from the outer rim of the cooler to a point in the ice-chamber desired for a water-line; B B, a tube for conveying the water from the reservoir L to the plug G, through which it passes into the tube G and thence into the ice-chamber N.

The manner of operating the cooler is as follows, viz: The ice being first introduced,

the cover F F is placed over the top of the` ice-chamber N and tube B. The water is then poured into the reservoir L L. The bottom edge ofthe cover not being water-tight, the water iows up to the top of and down through the tube B, through the plug G and tube C into the chamber N, the airin the ice-chamber being, by the pressure of water, forced out through the tube E until the opening inside the ice-chamber is sealed by the water rising above it; then, as no more air can escape no more water can iow in, and the water stands on a level with the top of the tube E until the ice begins to melt, when the volume of water is increased correspondingly. This extra supply, made by the melting of the ice, is drawn oit' thus: The plug Gr being turned for drawing off water, the saine motion shuts the opening I and allows no water4 toilow from the reservoir L through thetubes B and Cinto the ice-chamber; consequently any water drawn oli' must reduce the quantityin said ice-chamber. At the same time and by the same movement of turning the cock for drawing water the air-tube D D is opened, thus allowing air to rush in and fill the vacancy made. by the water drawn ofi'. When sufficient water has been drawn the motion of shutting 0E the water shuts the air-tube D and opens the connection between the supply-tubes B and C and the reservoir L; but no water can ow Ainto the IOO ice-chamber unless the drawing off has reduced the Water therein below the air-tube E, in which ease the air would be foreed out and the Water would again ow in until it had sealed the air-tub'e E by rising above the openlng.

As the top of the supply-tube B extends some distance above the bottom of the reser- Voir L the Water iiowing into the iee-ehamber is n ot taken 'from the bottom of said reservoir; consequently'the greater part of any sediment or impurities contained in the Water will settle and be deposited on the bottom of the reser- Voir, and not enter the ice-chamber at all.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a Water-cooler, the combination of the reservoir L, the ice-chamber N, the tube B, connecting with the twoavay cock A G, and the cover F, constructed and operating substantially as and for the purposes set forth.

2. In a water-cooler, the combination of the two-Way oook A G, tubes B and C, ice-chamber N, air-tube H, reservoir L, and cover F, constructed and operating substantially as and for thepurposes set forth.

3. In a water-Cooler, the combination of the air-tube E, ice-chamber N, cover M, tube B, and reservoir L, constructed and operating substantially as and for the purposes set forth.

4. In a Water-cooler, the supply-tube B, extending above the bottom of the reservoir L, in combination with the ice-chamber N and the tube A and plug G, substantially as set forth.

5. In a water-cooler, the air-tight cover F, in combination with the ice-chamber N, reser- Voir L, and tube B, substantially as and for the purposes set forth.

In testimony whereof I atlx my signature in presence of two Witnesses.
