APPARATUS FOR PURIFYING WATER.

SPECIFICATION forming part of Letters Patent No. 472,641 dated April 12, 1892. Application filed March 24, 1891. Serial No. 386,198. (No model.)

To all whom, it may concern,- ing-chamber to permit the free escape Of the Be it known that I, LEROY S. LEWIS, a citivapor generated from. the water, and where zen of the United States, residing at East this tube passes through the chamber c it is Hartford, in the county of Hartford and State surrounded by a jacket of non-heat-conduct- 5 of Connecticut, have invented certain new ing material, as asbestos, which is held in and useful Improvements in Apparatus for place by a larger tube a to prevent the colder Purifying WVater, of which the following is a water in the supply-chamber from condensfull, clear, and exact specification. ing the vapor before it passes out of the tube.

The invention relates to the class of appa- The tube a above the vaporizer is preferably IO ratus for freeing water from chemically-disenlarged, forming a chamber a to allow a solved and mechanically-suspended impurifree expansion of the vapor or steam, so it ties; and the object is to provide a simple, may free itself from any globules of unvaporcheap, and easily-operated apparatus of this ized or boiling liquid and not carry it along class requiring but little attention, whereby the tube (V, which connects the vaporizer with I 5 all animal and vegetable bacteria and organthe portable tubular air-condenser l).

Fig. 4 is a vertical section of central tube and through that to the chamber the vaporizer.

This vaporizer, which through the outlet-tube, so that the water is made of thin metal, preferably consists of which passes through the openings fills the a large upper chamber a, having an inlet a cup before running over, and seals the outlet for receiving and holding the supply of water to prevent the escape of vapor or steam.

This tray is supported at a slight incline source of heat. A small pipe of, usually bent by brackets connecting the legs b depending in several coils, connects the lower part of from the bottom of the condenser, and its 5 45 the chamber a with the lowest part of the bottom surface is roughened by ridges d chamber a so that as the water in this latter bosses 0 in order that the water of condenchamber is vaporized and the vapor rises sation which escapes from the condenser will through the tube a water from the supplyspread out ina sheet, and in running slowly to chamber enters through the pipe d to keep the receiving jar, barrel, or other receptacle d 50 the heating-chamber full. The tube a passes will be obliged to travel an uneven and broken from the center and highest part of the heatcourse, so that all portions will be brought into contact with and subjected to the influence of the atmosphere, whereby the purified water, which has lost its air during the boiling, will again absorb oxygen and become palatable.

Any kettle or common vaporizer may be used in which to generate steam; but with that form shown the vapor can be generated quicker than with an ordinary vessel. ater from the supply-chamber a passes through the pipe a to the heating-chamber a and the vapor generated collects at the convexed top of this chamber and passes upward through the tube to the chamber a, where it parts with its moisture and passes to the chambers of the condenser and is condensed by contact with the sides of the tubes through which it circulates. The vapor which collects in the conical upper chamber is drawn into the tubes by the condensation of the vapor which comes in contact with their sides, as their extent of surface exposed to the atmosphere permits a rapid radiation of heat. The water of condensation in the upper chamber passes through the tube 1) to the chamber b while the condensed vapor in the tubes passes directly to this chamber and escapes through the trapped outlet at the bottom and overthe walls of the cup into the aerating-tray. From this tray, where it is aerated, the purified water is allowed to run into any suitable receptacle to remain until used.

The vaporizer can be placed on any stove or over any gas or oil burner, while the condenser, which occupies but little ground-space, can be moved to any closet or cellar at a distance from the source of heat and be connected by fixed pipes, so that a quantity of pure water fully aerated may continually be making and a supply always kept on hand without any particular attention or attendance. When the vaporizer-tube is disconnected from the condenser and the cap at the apex of the upper chamber of the latter is removed, the tubes, beingheated, cause a current of air to pass through them, which dries out all moisture. Of course the boiling of the water destroys all bacteria and disease-germs, and the vapors leave all mineral and other foreign substances in solution or mechanically suspended in the vaporizerand the water reaches the aerating-tray in a pure state. of the condenser are quite thin and, having considerable surface, readily part with their heat, so they do not become hot enough to render them useless.

I claimas my invention- A water-purifier consisting of a vaporizer, a condenser connected therewith, having a series of vertical steam-tubes connecting two chambers and surrounded by the atmospheric air, a trap-outlet from the lower chamber, an inclined aerating-tray located below the trapoutlet and provided with an embossed and ridged upper surface on the upper face of its bottom, whereby an unevenness is provided, over and around which the purified water must pass to the receiving vessel or receptacle, substantially as specified.
