AIR-MOISTENING AND VENTlLATlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 511 ,897, dated January 2, 1894.

Application filed February 1, 1893. Serial No. 460,537. (No model.) Patented in Germany January 18, 1891,1Io. 58,902, and in England September 9, 1891, No. 14,765.

To aZZ whom it may concern:

Be it known that we, EUGEN KLEINER, WAL- TEE BOKMAYER, and OTTO HOEEMANN, subjects of the Emperor of Austria-Hungary, re

siding at Modlingmear Vienna, Austria-Hungary, have invented certain new and useful Improvements in Air-Moistening and Ventilating Apparatus, of which the following is a specification. The invention has been patented in England, No.14,765, dated September 9,1891, and in Germany, No. 58,902, dated January 18, 1891.

This invention consists in various improve- 5 mentsin air-moistening apparatus (with which is combined a ventilating arrangement) whereby the consumption of water or other liquid used in such apparatus is reduced to a minimum and a powerful conveyance of air to the ventilating space, or the space to be filled with moistened air, is obtained, and the liquid is also finely scattered, sprayed or vaporized Without the formation of drops in the space in question, and in which the air drawn 2 5 into the apparatus is forced to pass through a curtain or cone of water and is thereby not merely washed but also saturated with moisture. In order to attain these results in this air-moistening and ventilating apparatus, we 0 cause two jets of liquid of preferably diderent sizes to play under pressure, upon each other in exactly opposite directions for the purpose of forming a hollow cone of water, whereby the air surrounding the apparatus is 3 5 not only powerfully drawn into the same but also a very fine comminution of the liquid is produced; and the air drawn in is saturated with the same.

In most of the moistening apparatus hitherto employed the comminution of the liquid takes place by means of sprayers which are provided with numerous openings mostly of the thickness of a hair in size for the passage of the liquid which openings very soon become stopped up by the mineral impurities in the water and the impurities in the air ployed in this apparatus has whereby the continuous effective action of the sprayer is considerably impaired and further these apparatus require constant supervision and cleansing.

The suction and pulverizing nozzle emonly two proportionately large discharge-openings for the liquid which is to be coinminuted so that no stoppage can take place or at least extremely 5 5 rarely, because the impurities in the liquid even if they have not been already retained by the fine meshed filter sieve arranged in the supply pipe can pass freely through the openings. By this means the action of our apparatus remains constant and reliable even when working for weeks without any expensive supervision and cleaning as in order to secure a faultless working of our apparatus it suffices from time to time, to cleanse the filtering sieve box in the supply pipe which can be done in a few minutes and with little manipulation.

In order to allow of our invention being better understood, an air moistening and ven- 7o tilating apparatus provided with the above named improvements will now be more particularly described, reference being had to the accoinpanyingtwo sheets of drawings, in which- Figure 1 (Sheet 1) shows a vertical section of the apparatus on the linef g of Fig. 3. Fig. 2 is a vertical section on the line (Z c of Fig. 3. Fig. 3 is a plan of the apparatus. Fig. 4 shows separately and on a larger scale the double nozzle employed to spray or coniminute the water and draw the air into the apparatus. Fig. 5 (Sheet 2) shows a modified form of the apparatus.

Referring in the first place to Sheet 1 the apparatus consists of preferably a globular case A with a cylindrical neck I) which ends in a flat cruciform shaped disk or shell D. This has four radial discharge passages E for the exit of the mixture of air and moisture from the apparatus the spaces between each of the passages E being closed in by means of plates.

In the neck b there is placed a circular piece is conveyed under pressure R with cross bars which evenly divides the air saturated with moisture passing through the appararus and allows the same to deposit in the form of drops any excess of moisture. The point of a distributing cone G extends into the neck 12 the base of which cone lies in the plane of the cover of the shell D. The

.ends of a stirrup piece B are bolted or riveted at two opposite points of the neck I) and this piece serves for attaching the apparatus to the ceiling of the chamber which it is desired to ventilate. The case Ahas at its lower part a cylindrical projection c. The device for drawing air into, the apparatus and for spraying the liquid and washing and saturating the air thus drawn in with the finely sprayed liquid is arranged in a cylinder 0 penetrating sidewise into the case A. This device consists of the two nozzles d d, Fig. 4 (carried by one bracket) the nozzles being of preferably difierent diameters to which the liquid by means of a pipe M the liquid emerging from the two nozzle orifices in the form of two jets of different diameters and in exactly opposite directions. The nozzles are connected together by the pipe d Owing to these jets of liquid acting in opposite directions upon each other a hollow liquid cone or curtain (shown in dotted lines in Figs. 1 and 4) is formed which vigorously draws the air into the apparatus through the upper opening in the cylinder 0 which may be controlled and adjusted as to size by means of the lid H. The air drawn in is forced to traverse the cone or curtain of liquid or spray on its way through the cylinder 0 into the case A by which means it is not only washed and freed from all impurities but on its further course through the case A is also saturated with the pulverized liquid therein contained and passes out of the apparatus in the finest subdivision through the passages E into the chamber which is to be ventilated. The liquid on its Way to the double nozzle (1 01 passes first through a filter box S Fig. 2 placed in the'supply tube M and provided with a fine sieve. The liquid which collects in the case A in the form of drops passes through a valve z provided in the the return pipe N and is thus removed from the apparatus. The modification shown in section in Fig. 5 on Sheet 2 is a somewhat simpler arrangement of apparatus but does not differ essentially from that already described. We provide a cylindrical casing is open at the top and bottom. The foot of the casing is splayed as at k and rests upon supports 1 which separate the splayed foot of the casing fora certain distance from an inclined flange m. Bolts 72. hold together the flange m, supports Z and foot 7 Thus there is practically an open annular space between the foot 70' and the flange m. In the center of 4 the flange m there is formed a drip well oand above the Well 0 there is a cover 10 soldered to the upper end of the screw g which passes bottom plate J into through a nut rsoldered to the flat bottom of the well. A conical wall 8 protects the screw and nut from the surrounding water. The cover 19 is of curved section as shown and around the lower edge is a series of recesses 12 which allow water to flow into the drip well 0 from the flange m. By turning the screw q the cover 19 can be raised so as to allow of access for cleaning purposes to the well through the annular space. A pipet takes away the deposited water from the drip well. The double nozzle 01 d is situated near the top of the casing is and is supplied with water under pressure through the p pe u. The apparatus is suspended by the bridle '0. When the apparatus is. in operation the cone spray produced by the double nozzle d d 1s is dashed against the side of the casing 70 and descends with the air which is drawn in at the top to the foot of the casing where the mixture of air and water issues through the annular space as a fine mist or impalpable vapor, thoroughly moistening the atmosphere of the room into which it is discharged. The water which may be deposited in the interior of the casing is flows down and is directed by the inclined ledge w to the drip well, and any moisture trickling down the under side of the foot 70 is diverted by the archedslips as which stand perpendicularly from the flange to fall upon the inclined flange m. We also form a secondary gutter by adding an outer extra ring y at the extreme edge of the flange m. This catches any condensed drops that might have been blown to the edge of the ring. To purify the water and render the nozzles less likely to be choked by foreign matter in the water we pass the feed through a filter valve 2.

We claim as our invention- 1. In combination, a mixing or saturating chamber having lateral delivery passages, an air inducting cylinder connected with said chamber and having an inlet opening for the admission of air and arranged to convey the same to the mixing chamber and the liquid spraying device located in the said air 1nducting cylinder, and arranged to force the air and liquid spray through the air inducting cylinder into the mixing chamber substantially as described.
