by air may be made humid or moist for various urposes.

T 1e invention comprises means whereby waterused to moisten orhumidify the airis itselfutilizedfortheblowingmechanism,whereby air currents are set up 'so that the air is drawn through a moistening chamber and then distributed to the point of utilization.

In the practical embodiment of the invention there is provided a suitable casing in which is located a water motor-drivingfans which are used for the purpose of propelling the air to distribute the same about the room or compartment where the air is to be kept in a humid or moistened condition. The water after being used to drive'the water motor is caused to traverse the in 'coming air current in thin streams or sheets so'that the air before reaching the pro elling means driven by the come incontact with the escaping water and thus be thoroughly moistened or humidified. After the water has passed through the motor-and through the incoming air stream it is-permitted to esca e through a suitable drain.

n accordance with the present invention provision is also made for insuring the assage of clean water only tothe motor am the humidifying portion of the device by provid- 'ing suitable screens or filters. In this connection provision is made for the cleansing of these screens or filters from time to time to prevent the latter from becoming clogged.

The invention will be best understood from a consideration of the following detail description taken in connection with the accompanying drawings forming a part of this specification, in which drawings- Figure 1 C is an elevation of the device.

Fig. 2 is a cross section of thedevice on a vertical plane in the axis of the motor shaft, the said motor and fans driven thereby being shown in-elevation. Fig. 3' is a vertical section through the filter and adjoining parts on a larger scale than shown inFig. 1, and Fig. t is a cross section on the line A-B of Fig. 3.

In the drawings, there is shown a casing 1 of an suitable shape, but referably eylmdrica This casing is-close at the upper end by a ca orcover 2and is open at the lower end. elow' the lower end of the casin 1 there is ajtrough or receptacle 3 somew at larger in diameter than the casing 1 and hung therefrom and spaced by hangers 4 connects to the casingl and the trou h 3. The bottom of thereceptacle 3 inchnes toward the center and is there connected with a drain or waste pipe 5.

The device is shown as supported upon brackets 6 and 7, fast to a support or post 8,

which may represent the side wall or any por-' tion of the frame of a building, wherein the humidifier is located.

Mounted within the casing 1 near the upper end thereof is a water motor 9 provided with a suitable casing 10. This water motor may be of any of the ap roved constructions and consequently nee s no s ecific description. The water motor shat jects through the side of the casing 10 to near the inner wall of the casing 1, which latter at these points is rovidcd with diametricallyopposed throu 1 o enings 12. The shaft 11 terminates wit in t e casing 1 and at its ends carries fans 13 in close relation to the openings 12 and arranged to drive air out through the said openings, and the bottom of the easing 10 of the water motor has an openin .14 for the esca e of water that has been use for actuating t e motor. The fans 13 are, of course, right and left hand fans.

The casingl below the water motor is a conical screen 15 immediately below the opening 14 and with its base resting on supports 16 at the open end of the casing. These supports 16 may be made by indentin the walls of the casin 1 or may be made in any other manner. T e arrangement is such that water escaping through the openin 14 will be caused to flow down the conica screen 15, some Water flowing through the screen and some 'findin its way to the outer edges of the base 0% the screen and all the water finally gravitatin into the receptacle 3 and flowing out throng the drain pipe 5.

The fans 13 cause the air to flow into the casing 1 through the lower open end of the same between the said lower endv of the easing and the receptacle 3, and the inflowing air streams can only reach the fans 13 by 't 11 propassing'through the screen 15. The inflowlng ir streams, however, must pass throu h thin streams of water flowing down t screen 15, and the air will thus absorb more or less water and thereby become moistened or become humidified and forced out through the openings 12.

entered by a bushing 21, and between this and includes a cut-off valve 29.

bushing 21 and the lower end of the cylindrical member 18 there is confined a cylindrical screen 22 concentric with the casing 17. The u per end of the casing 17 is entered by a pipe 23 and the bushing 21 receives a p pe 24 connected by a union 25 to another pi e 26 leading into a valve 27, from which atter thereleads a pipe 28 to the receptacle 3 so as to empty therelnto. The pipe 23 leads from any suitable supply of water under ressure u pose, now, that water is admitted throug the pipe 23, it. finds its way to the nterior of the screen 22, and assuming that the valve 27 is shut ofl the water will flow into the interior of the cylinder 17, and out through the nozzle 16 against the buckets of the water motor setting the latter in motion and thereby propelling the fans 13.. As the water is used it escapes through the opening 14 to the screen 15 and ultimately into the receptacle 3. The

Y rotation of the fans 13 causes air currents to be forced out through the openings 12 and air is drawn into the casing 1 through the screen 15, becomin moistened or humidified as before explaine The screen or filter 22 serves .to maintain the incoming water-in a clean or pure condition so that there is no danger of contaminating the upper surface of the screen 15. If

I the incoming water be at all dirty the inner surface of the screens 22 ultimately becomes contaminated, then by opening the valve 27 the water flowing in through the pipe 23 wi l find its way into the receptacle 3 without first passing to the water motor, and any material which has accumulated upon the inner surfaces of the screen 22 is washed off by the flow of water and ultimately finds its way into the drain 5. The screen 22 S t may thus be cleanse om time to time, as

may be found advisable.

The construction of the nozzle 16 is best indicatedin Fig. 4, where there is shown a nipple 30 screwed'at one end into the body of the nozzle and at its other end receiving a cap 31 having a central bore or assa e 32. The cap 31 confines a glass bloc 33 in the corresponding end of the nipple against an annular shou der 34.1'ormcd on the interior of the nipple. Through the block 33 is an axial the effective size of the bore of the nozzle. The passage 32 in the ca 31 is of such. size as to permit the use of bloc 's 33 having bores of different diameters so that the size of the stream may be varied by changing the blocks 33 without the necessity of changing the cap 31. 1

The glass block is used because of its resistance to wear and because it maybe readily renewed, or changed if it be desired to vary the size of the jet. The structure forming the subject-matter of the present invention provides a means for supplying clean water to the water wheel and from thence to the screen 15. All the air reaching the fans 13 must pass through the body of water passing over and through the screen 15 and therefore the air is thoroughly washed and also cooled by its passage through such body of water.

thereof.

7. In a humidifier, means for producing air currents, a water motor for driving the said means, and a nozzle for directing water to the 8. In a humidifier, a means for producin air currents, a water motor for driving sai means, and a nozzle for directing water to the water motor comprising a nipple, a block loosely and removably seatec therein and having a bore of substantially the same diameter throughout, and a cap on said nip le confining the block to'its seat and provl ed with a perforation for the passage of water escaping from the bore of the block.
