APPARATUS FOR MOISTENING AIR.

SPECIFICATION forming part of' 1'.|ette'rs Patent No. 470,693, dated March 15, 1892.

Application and my ze, 1391. sani 110.401,08?. (no maar rae-naa in France september 11, lese, No. 192.906; in neigium September 17,1888, No. 88,288: in Switzerland November 15, 1888, No. 54, and October 13, 1890, No. 2,7455 in Italy December 6, 1888, LVII, 252, and in England January 23, 1891, No. 1,268.

To if/ZZ whom it may concern:

Beit known that I, EMILE MERTZ, a citizen invented certain new and useful .Improve-z ments in Apparatus for Moistening Air, of

which the following is a speciication, andT whiclLhas been patented in France by pat-` ents of addition, dated October 13, 1890, and January No. 2,745, dated October 18,1890, and by patent of addition No. 77, dated January 28, 1891, l to Swiss Patent No. 51, dated November 15, 1888; in Italy by patent of addition, dated? March 28, 1891, Vol. 25, 28,987, Vol. 42,252, to patent dated December 6, 1888; to English Patent No. 1,268, dated January 23, 1891; Belgium patent of improvement, dated January 28, 1891, to Patent No. 88,288, dated September 17, 1888.

The present invention relates particularly.

to means for cleansing the water-atomizing valves of apparatus for moistening air.

According to this invention I connect the atomizing-surfaces,against Which the streams of wat-er impinge as they issue from the nozzles, to a movable rod, so that by a change in the position of this rod the atomizing-surfaces are made to press upon the projecting .points of the plugs of the nozzles (which plugs are provided with capillary channels) and press the plugs back in their cases, and the channels of the plugs are in consequence antomatically cleansed by the water which issues from the valve under pressure.

In order to enable this invention to be fully understood, I will describe how it can be carried into practice by reference to the accompanying drawings, in which- Figure 1 is a vertical axial section of an air-moisteuing apparatus constructed according to the preferred form of my invention. Fig. 2 is a horizontal section thereof cut immediately below the beaters'F in Fig. 1. Fig. 31s a vertical mid-section of a construction of the apparatus adapted to receive its supply of air from outside the apartment in which it is located. Fig. f1 is a horizontal section thereof takenin a plane just below the beater F. Fig. 5 is a fragmentary vertical 22, 1891, to Patent No.'192,906, dated September 11, 1888; in Switzerland by Patent section showing a modified form of a'toniizingsurface. Fig. 6 is a fragmentary plan View is a detached view showing in elevation another modied form of atomizing-surface.

Fig. 8 is a fragmentary plan view of the modied form of spraying-surface and its carrier shown -in Fig. 7. Fig. 9 is a detached view showing one of the spraying-nozzles on a large scale in'vertical axial section. Fig. 10 is a plan View of the nozzle shown in Fig. 9. Fig. 11 is a side elevation of the plug of the nozzle shown in Fig. 9, and Fig. 12 is a cross-section of the plug shown in Fig. 11. p Referring to Figs. 1 and 2, let A represent .the well-known filter; B B, the nozzles, which consist of socketse and movable plugs f, one of said parts being grooved; C C, the atomizing-s-urfaces; H, the carrier therefor; L, aplate or ring connected to the carrier H; E, the usual fan; F, the usual beater-bars, and D the Well-known turbine for driving the fan and beater-bars. G is an inclosing case of usual construction. The nozzles B may be of any well-known construction, and consist, essentially, of asocket and movable plug therein, one of said parts having discharge-grooves, and said plug normally restricting the ow through the nozzle, but constructed when displaced to permit an increased flow in order that the 'water rushing through the nozzle may cleanse its discharge-grooves.

In the construction `hown in Figs. 9 to 11 the socket c is cylindrical and has a slightlyconed seat, and the plug f is inclosed in the socket and has a conical portion normally en- `of the modification shown in Fig. 5. Fig. 7

gaging the coned seat of the latter, being in v other respects movably located in the socket and adapted to be displaced inwardly thereof to open the nozzle. To permit this displacementgthe plug is formed with a proj ecting. point CZ at its outer end, which extends above the shell c and against which the atomizing disks or surfaces C abut to open the nozzle, as will be described hereinafter. In this construction the plug f is provided with small capillary outlets or grooves g and with larger tapering grooves h, and au vannular groove z' is turned out near the top of the plug and a larger annular recess j is provided at the lower V1 oc end of the groove h. The grooves h and g serve as passages for the water as it is discharged from the nozzle, as heretofore, while any impurities in the water which are held back by these grooves will collect in the groove c' and the recess j during the normal operation of the nozzle. Vhen the nozzle is to be cleaned, it is only necessary to displace the plug f, whereupon the tlow through the nozzles will be increased to such an extent that it will wash out the accumulated impurities in the groove t', recess j, and the grooves g and h. When the cleansing operation is cornpleted, the plug f upon being released resumes its normal position and the nozzle throws out the ordinary jet' of spray. This principle of construction and operation is well known.

In the apparatus shown in Figs. l and 2 the water, purified by the filter A, is driven under pressure out of the nozzle B from below upward against the disks C, which have their surface arranged in steps, and in this way the water is converted into a condition of extremely ne division. The water under pressure also drives a turbine D, which is arranged under the nozzle B, and upon the shaft of which a fan E and a cross-piece F are fixed. The fan E, as well as the cross-piece F and the atomizingdisks C, is placed within a casing- G, open above and below, so that by the rotation of `vthe fan E, which revolves with the turbine D, a current of air is made to pass through the apparatus from below upward, and as the result of the contact of this current of air With the finely-divided water the air takes up moisture and passes through the annular opening ct of the casing G of the cylinder into the apartment which is to be moistened or cooled, as the case may be. The crosspiece F, which rotates with the ventilator, serves to drive off laterally onto the casing G the drops of Water which find their way onto the upper surface of the disk C, and thus prevent their passage through the fan E. The number of atomizing-disks O is equal to that of the nozzles B, and these graduated disks C are attached to a common carrier H, which corresponds in form with the annular arrangement of the nozzles. The carrier H is secured by means of screws c to two lateral projections b of a nut K, which is supported by the vertical screw I. To the said projections of the nut K are also attached the ends of a nearly-circular plate L, and the latter is in addition connected with an arm CZ of the diskcarrier H, so that the position of the plate L and that of the disk-carrier H may be changed with that of the nut K. The spindle of the screw I is led at one end through one of the arms M M M (which are cast in one piecev with the casing of the turbine and which connect the latter with the cylindrical casing G) and at the other end through the arm N of the exit for the waste water of the turbine. At the end of the spindle of the screw I is attached a 'handle or a ring' P, and a spring Q, which rests below upon the arm N and is in contact above with a socket R, fixed to the spindle I, presses the spindle I constantly upward. The atomizing disks or surfaces C are constructed when moved toward the valves B to engage the projecting ends d of the nozzleplugs f and displace the latter. Thus when the nozzles B are to be cleaned itis only necessary to draw down the screw-spindle I by means of the ring P, so that the spindle with the nut K and the atomizing-disks C move downward together until the disks C press upon the points d of the plugs and drive the latter back into their casings, so that then the waterwhich streams out of the nozzles under pressure can carry off with it the impurities which adhere to the plugs. As soon as the pull upon the spindle I ceases the latter, with the disks C, are brought back into their normal position by means of the spring G, which has been previously compressed by the drawing down of the spindle I. The ring orplate L is constructed to move towardand-ffsurround the nozzle B when the surfaces C operate to open the latter in order that the discharge from the nozzles maybe intercepted, and thus be prevented from escaping below the casing G. The ring L has two recesses Z, so that when the spindle I is drawn down the arms M M may not interfere with the Inovement of the ring L. The ring or plate L is further provided with a slot m, so .that when the spindle I is drawn down the ring L may not strike against the inlet S of the'watersupply. By means of this ring L, which slides upon the inner surface of the cylindrical casing G, the movement of the atomizing-disks C in any direction but a vertical one, when traction is made upon the spindle I, is prevented. In addition to this, the ring L also serves to prevent the water i' rom being thrown into the room when the nozzles are being cleansedthat is to say, when traction is made upon the ring P of the spindle I. A revolving disk k is further attached to the spindle I, so that the screw I can be turned by hand, and by this rotation the nut K, which is united with the atomizing-plisks C can, together with the latter, have its position altered more or less, so that the atomizing-disks C are made to approach or recede from the nozzles, by which means the air as it streams through the apparatus is moistened in a correspondingly greater or less degree.

In the apparatus shown in Figs. 3 ande the casing G is secured to hollow bracket P', screwed to a well, which, by means of openings capable of regulation, is in connection with the outer air as well as with the air of the apartment, so that a mixture of the outer fresh air and of the unpurified air of the apartment can be moistened in the apparatus. The fan E then takes up the air which is to be moistened from the hollow bracket P and forces it after it has been moistened through the round opening a into the atmosphere of the apartment. The opening n, by means of which the hollow bracket P com` IOO IIO

municates with the outer air, is provided with amovable slide o, while the lateral openings p, by means of which the hollow bracket P communicates with the air of the apartment, can be regulated by the slide q. The slides q are provided with buttons for the purpose of altering their position, and when the position of the slides is changed the slides q are guided by plugs which slide in slots t, arranged between the openings p of the side walls of the bracket P.

As in the apparatus shown in Figs. l and 2,'tl1e water under pressure flows first through the filter A before it reaches theturbine D and the nozzles B.' The axis of theturbine D also carries a cross-piece F and a fan E,

and between the cross-piece Fv and the nozzles B are atomizing-disks C with graduated surfaces attached to a common carrier H. The'latter is `also connected with a nutrK, supported by a screw I, and a ring L is attached to the nut K and also to the arm cl of the disk-carrier H. The screw-spindle I is guided by a lateral projection MU of the casing of the turbine, and by the arm N connected with the outflow-pipe of the waste water, and a spring Q, kept in position at one end by the arm N and at the other by-a ring R in the spindle I, presses the said spindle constantly upward. vBy pulling the ringP of the chain which is connected to the spindle I the disks C are, as in the apparatus shown in Figs. l and 2, made to approach the nozzles until they rest upon the points d of the plugs and press the latter back into the sockets, so that the plugs of thenozzles are automatically cleansed by the water which streams out under pressure. By turning the spindle I the atornizing-disks C can also be shifted nearer -to or farther from the valves in order to more or less moistenthe air which flows through the apparatus. The guidingring L of the disks C is also provided with slots a, so that the lugs c of the hollow bracket P', by means of which the casing G is secured by screws m to the bearer P', do not interfere with the change of position of the ring L. The ring L has also a slot 'm to avoid any thrust upon the inlet-pipe S of the Water-supply by the ring L. A cap 'y is iitted to the spindle I for the purpose of diverting the drops of water which fall upon it, so that no water may run along the spindle and escape from the apparatus. In both these apparatuses for the moistening of air lubricating-oil is placed in a reservoir U, (which surrounds the pivots of the common spindle or axis of the turbine D, the cross-piece F, and the fan E,) whence it can be drawn 01T through a tube ,egattached to it and provided with cocks, and new oil poured into the reservoir U by means of a tube V.

Instead of several atomizing-disksA L@ as shown in Figs. 1 to 4, a single atoniizing-ring C', with graduated Surface and attached to the carrier H, as shown in Figs. 5 and 6, might be employed for several valves. The atomizing-surfaces might also consist of obliquelyplaced vanes orwings C, attached toa com- 1mon carrier H, as shown in Figs. 7 and 8.

It will loe understood that I do not limit myself to the particular construction and arrangement of the apparatus as hereinbcfore Adescribed and shown in the drawings, as this ,may be'variously modied without departing jfrom my invention.
