ASSIGNMENTS, TO GEORGE E. PARKER, OF SAME PLACE.

APPARATUS FOR DISJTILLATION ANDAERATION OF WATER.

STPECIFICATION forming part of Letters Patent No. 534,412, dated February 19, 1895.

Application filed October 8,1892.

To all whom it may concern:

Be lt klIlOWll that I,-JHN H. VINTON, of Boston, 1n the county of Suffolk and Stateof .Massachusetts, have invented an Improvement in Apparatus for Distillation and Aeration of Water, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

The object of my invention is to provide means for obtaining, from an apparatus of moderate size and simple construction, a copious supply of distilled water, properly aerand efficient both as to construction and operation.

The entire apparatus is preferably coated with block tin wherever the water to be dis-' tilled comes in contact with it. I

Following is a description of the apparatus shown in the drawing, and of the method by which drinking-water is prepared in the apparatus.

Upon a kettle, K, within which is a coil of steam-pipe, S, rests the condenser, 0, whose lower edge fits the flange, F, of the kettle K. The condenser O is in two parts; a cylindrical jacketJ and an interior dome D. The bottom of the condenser O is partly closed in by the annular diaphragm R. A large aperture, A, is left in this diaphragm R, and the flueT serves as a continuation of the aperture A into the midst of the space inclosed by the dome D. Within the dome is a gutter G, which runs around the sides, inclining downward to the outlet 0. Around the lower rim of the condenser O are a number of holes h, h, which admit air to the dome D above the diaphragm R.

Cooling water is admitted to the space '21 between the dome D and the jacket J through the pipe 10' and flows off through the. pipe 12 which delivers the overflow to a pipe 19 indi- Serial No. 443,204. (No model.)

rectly through the cup '1 from which the pipe 19 takes as much water as is necessary to maintain a constant level of water in the ket tle K. A pipe 19 serves to withdraw sediment laden water from the kettle K.

/V is a light ball-valve which serves to relieve any excess of pressure which may be developed inside the dome D.

The operation of this apparatus is as follows: The kettle K, and jacket-space n, are filled with water, steam is turned on in the pipe S, and the water in the kettle raised to boiling point. Steam from the kettle Krises through the flue T, and emergesinto the dome D, which, at the outset is filled with air at the temperature of the surrounding room. The steam, intermingling with this cooler air, is condensed thereby, and forms clouds of watery vapor, in intimate mixture with the air by which this initial condensation is effected. The vapor is then deposited on the surface of the dome D, collects in drops, which run into the gutter G, and out through 0. After this first condensation and aeration, the process continues, means being provided fora constant admission of air into the dome D. These means are automatic. Theintroduction of air into the domeis a necessary result of thefirst condensation. The outlet 0 is made of such size that when the apparatus is discharging water normally, it shall run not more than about half full. The out-flowing current of water, by the action of surface friction, draws with it a current of air and vapor, which pass out of the-dome through the upper part of the outlet 0, which is, therefore, at oncean outlet for the distillate and a vapor-ejector. Responding to the outward current of vapor and air through the ej ector-outlet 0, air from outside flows into the dome D through the holes la -comes in contact with the flue T, is warmed, rises to the top of the dome, and condenses steam rising inside the flue T, as in the initial process just described. Except for the constant, though slight, difference in pressure caused by the outflow of air and vapor at O, the pressure inside and outside the dome Dis almost constantly the same. Occasionally an' accidental rise in pressure causes the valve V to rise,--but then only for amoment.

It is by the intimate mingling of air at the moment of condensation that the distillate from this apparatus is aerated completely; and at the same time, the employment of air as a condenser in. addition to the cool walls of the dome D, renders the output of this apparatus unusually abundant.

The jacket water, entering the space 71, at 79', serves to keep the lower portionof the surface of the dome D cooler than the upper re gions. By means of these contrivances, there is maintained in the apparatus a comparatively cold belt or zone. The cold jacket water entering at p, the airfrom without ens tering through h, h, and the prevention of steam eddies in the bottom of the dome by the operation of the annular diaphragm R and flue T, combine to keep the region in the apparatus in which the gutter G is located, cool enough to deliver a distillate in condition fit for bottling or transportation.

The apparatus shown is automatic. The

flow of jacket-water through the pipe 19 keeps the space at full while the overflow through 19 and the level-adj usterr delivers a constant supply of water to the kettle K.

It is sometimes advisable, on account of active ebullition in the kettle K, to provide means to prevent spatteringot impure water- 1. In a distilling apparatus, in combination with an evaporating vessel and a condenser, an ejector outlet, and an air inlet situated in the lower part of the condenser so as to introduce incoming air into the vapor as it rises from the evaporating vessel toward the surface of the condenser, substantially as described.

2. In a distilling apparatus the combination with an evaporating vessel and a condensing chamber of a directing flue extending from the evaporating vessel to a point within the condensing chamber near orabove the level of the lowest active condensing surfaces, an ejector outlet and air inlet situated near the directing flue substantially as set forth.

In a distilling apparatus, an evaporating vessel, a condenser, a diaphragm between them, partially separating the condenser from the evaporating vessel, an ejector outlet and gutter leading thereto, situated at or near the lowermost part of the condensing chamber, an air inlet so situated as to direct incoming air into vapors rising from the evaporating vessel, combined with a directing flue leading from the evaporating vessel and extending into the condenser above its lowermost condensing surfaces, whereby a cooling zone ,is provided at or nearthe gutter and outlet, substantially as described.
