To all whom, it In/[bf] cm'we'rnr Be it known that I, 'CLAREECE'BIZ'KEMRE citizen of the United:Stat'es,'residing at'Baltimore,-in the State of Maryland, have invented certain new and useful Improvementsin Apparatus for Distillingand Aerating Water; and I do hereby declareth'e ormatm be a full,- clear, and exact description'of theiin'vention, such as will enable othersskil'led in the IQ art to Whicli'it appertains' to make and use the same.

' This invention relates to apparatusfor dis"- tilling and aerating Water; and" it hasfor'i'ts object to provide an apparatus or the" class referred to Which'shall be automatic throughout, shall be simple, durable,"and inex sa sive inconstruction, and safe; certain, and eificient in operation.

To these ends my invention consistsin the features and is the construction;combine tion, and arrangement of parts hereinafter described, reference being had mule-accompanying drawin g, forming a part of-th'isspech fication, wherein is illustrated'a' vertical sectional view of my improved apparatus; v

Referring to the drawing, the smear 1 indicates a storage vessel for holding th'e'distilled-and aerated vv'ater, and'2 thecondensing vessel. The vessels 1 and 2- areprefe' ably made integral; the condenser surmount ing'and supported on the-storage vessel, with which it communicates by a central con: traet'ed neck 3. Seated on top of the corrdenser 2 is a reservoir 4 for containing the feed-water, which'is supplied to theres'ervoir by a service-pipe 5, leading'from any suitable source of V supply, and the water is maintained ata constant level in the reservoir by a ballcoc'l'c 6 of ordinary construction; The res rv'oir 4: forms the top of the condenser 2; and

o structed asfollows:

" grea es -a1simitatesamas ecannecte'd' at" one end tothe ccnciense'v; The'ops'aiai 1%. 705,406. (1% modeli) posite end of the elbow-pipe projects clownvard and is interiorly threaded, as shown, and within said threaded end is screwed a retort-shaped tube or boiler 9, closed at its lower eh'd,'as shown. Leading from the reservoir 4; is a" feed-pipe I pipe-elbow 8 at a point directly above the boiler 9, and between its ends it is preferably trapped; as at 11, passing up into the waterres'ervoir. The end of the feed-pipe 10 that is tapped into the pipe-elbow is reamed to form a tapered valve-seat, in which is adapted to's'eat' a needle-valve consisting of a rod 12, having a pointed end 13, that seat-s in the lapered valve-seat referred to, and having at tached to its'lower end a float 14, that is adapted to float in the water containedin the boiler 9. A tube surrounds the valve rod or stem 12 and depends from the end of the feed-pipe-10. The tube 15 acts asa guide for the rod 12 to guide the valve to its seat and also operates tolead the Water down into the boiler in such manner that it will not be sprayed'orbrought into intimate contact with the rising vapor or steam, and thus tend to condense the'latter before it passes to the condenser. V

Aburner 16 is arranged beneath the boiler 9'and'isconne-cted with a supply-pipe 17, leading from a suitable source of gas or oil suppry. "A cut-0d valve 18 is arranged in the supply-pipe 17 and is controlled by a lever 19, carrying at its end a float 20, that rests on the surface of the distilled water contained in the storage vessel 1. A branch pipe 21 leads-from the supply-pipe 17 to the burner 16 and is provided with a small jet-burner 22,'th'at is constantly lighted-and operates to ignitethe main burner 16 whenever the latter is supplied with inflammable material. Surrounding the boiler 9and the end or angle of the pipe-elbow S is a chimney-casing 28', and fixed to the exterior of the latter is'a hood'2e, that isopen' atits lower end for the a'dmis'sionof the atmospheric air. An injec'tor-tu'be fze is tapped through the bend or theel'bow-pipe', as shown, and leads'froni the space inclosedby the hood -24 to themterior of the elbow-pipe.

' J'orte'd by a"refrig'erator or cooling vessel 26,

which may conveniently form a base or sup- 10, which is tapped into the 1 Thestorage vesseld'rests upon and is support for the apparatus, and from the bottom of the storage vessel 1 leads apipe 27, which is bent to form a coil 28, terminating at its end in a draw-off cock 29. A block of ice or other cooling medium may be disposed upon or around the coil 28.

The operation of my improved apparatus is as follows: Let it be assumed that the water is at the level in the reservoir 4 indicated in the drawing. Then the water will flow through the pipe 10 into the boiler 9 until a predetermined level is reached in the boiler, upon which the float 14 rises and forces the valve 13 to its seat, thus closing the pipe 10 and shutting oif the supply of water to the boiler. The chimney-casing 23 will confine the heat from the burner 16 about the boiler, (and leads away from the apparatus the spent heat,) and the water in the latter will be converted into steam or vapor, which will pass by means of [he pipe-elbow 8 into the condenser 2. The heated air in the hood 24 forces its way through the injector 25 into the pipe Sand is materially aided by the current of vapor arising from within the boiler. The injector draws its supply of air from the atmosphere through the hood 24, where it is heated by the radiated heat from the burner and is thereby sterilized. The steam or vapor and the sterilized air intimately mix be fore their entrance into the condenser, and in the latter the steam or vapor is condensed and drops down in the form of aerated globules of water into the storage vessel 1, from whence it passes by means of the pipe 27into the coil 28, where it is cooled. From thelatter it may be drawn off by a faucet 29 or at the faucet 31. When the distilled water in the storage vessel 1 rises to a predetermined height, the ball-cock 18 will out 01f the supply of gas or oil to the burner 16, whereupon the vaporization of the water in the boiler will cease. When the consumption of the water reduces the level in the storage-chamber, the ball-cock will again open and supply the burner 16, which will immediately be ignited by the auxiliary burner 22, whereupon the distilling and aerating operation will be repeated. The distilling and aerating apparatus will thus be thrown into and out of operation by the variations in the amount of purified water held in storage.

By arranging the heating and aerating apparatus outside of the condenser the action of the latter is not retarded by the heater. Furthermore,by means of the valved arrangement shown and described the water from the reservoir is fed to the boiler automatically to maintain a fixed quantity of water therein. The body of water, being small, is more readily heated, and the flame need only be small to secure this result, making the presence of the apparatus in no wise objectionable on account of its heat.

By the means and arrangement shown the apparatus automatically operates to keep the boiler supplied with water and regulates the application of heat to the latter to maintain a constant supply of purified and aerated water in the storage vessel Without necessitating the care or attention of an attendant.

A relief-pipe 30 is connected to the condenser to convey away the surplus of air not absorbed by the vapor.

By making the boiler detachable in the manner shown it may be detached when desired and the sediment, scale, and insoluble matter removed.

As shown and described, the storage and condensing vessels are connected by a contracted neck 3. This arrangement is adapted for a twofold purpose: First, it gives to the condensing vessel an increased surface that is in contact with the atmospheric air, increasing its condensing-surface, and, second, it acts to check or retard the commingled air and vapor and hold it in the condenser until it is thoroughly condensed before being discharged into the storage Vessel.
