Application led December This invention relates to ahumidifying apparatus with which may be useda spray device Whieh is improved incertain particulars. The object of this invention is to provide a 5 humidifier which is susceptible of accurate control whereby to produce a desired moisture content in a given body of air, and also to simplify to a considerable extent the spray device used in connection therewith,so as to break up into exceedingly small particles the water which supplies humidity to the air.

An exemplification of this invention is set forth in the accompanying drawing in the manner following:

Figure 1 is a'front elevation device; y

Fig. 2 is a transverse section therethrough taken on line 2-2 of Fig. 3;

Fig. 3 is a longitudinal section therethrough taken on line 3--3 of Fig. 2;

Fig. 4 is a fragmentary detail in perspective of one of the bands which is mounted adjacent the'periphery of the spray device;

Fig. 5 is a view in plan of the humidifier cabinet, a portion of the near wallthereofbeing broken away .to exhibit the arrangement of the several operating units; l

Fig. 6 is av rear elevation thereof;

Fig. 7 is a vertical section through the humidifier cabinet taken on line 7-7 of Fig. 5; and

Fig. 8 is a front elevation of the humidifier with the shutters and heater therein broken away in different planes to exhibit the interior construction. j

Referring particularly to Figs. 1 to 4, the spray device therein shown comprises two units, a rotor A and a stator B. The rotor may consist of'a casting having a pair of 3 spaced parallel walls 10 and 11 which extend angularly from'ahub 12 after the manner of a shallow cone'.v Connecting the two walls and extendingbetween them are radial vanes 14 which proceed inwardly from the periphof the spray eries'of the walls to a point substantially half.

way toward the center of the` rotor. The inj ner ends 15 of the vanes are'curved to one side, and all in Vthe same direction, as shown best in Fig. 2. The outer wall 10 is provided centlally with an axial sleeve 16 wherein is re- 50 ceived one end of a. driving shaft 17 to which the rotor is fixed'ly connected. On its inner side the wall 10 is also curved forwardly to an axial point 18 in general conformity with the curvature 19 which joins the inner wall 55 11 with the hub 12.

Theouter wall of the rotor is shown as having its periphery extended slightly beyond that of the inner wall. By this arrangement I am enabled to mount on the periphery of the outer wall a band 20 which carries' a plurality of wings 21 extending across the ends of the vanes 14. Between these wings and the periphery of the inner wall 1l is a space suiiicient for the accommo- 65 dation of a complementary set of wings 22 whichl extend laterally from a second band 23 having a mounting on the stator the form o1 which is preferably that of a spider plate, as f shown. The arms of the stator are joined to a iange 24 upstanding from a bearing box 25 in which is journaled the hub 12 of the rotor. Any suitable means for providing a water-tight joint between the hub of the rotor and .its bearing may be used, sunch as the packing 26 and gland 27. i

From the lower side of the bearing box is extended a nipple 28 in connection withvan intake pipe 29 through which water is taken in to the spray device. Rotation of the shaft 17 causes the rotor to be revolved with a consequent turning movement of the vanes 14 and outer wings 21. The direction of the rotor movement is as indicated by the arrow in Fig. 2. A suction effect is thereby created sufficientto draw through the pipe 29 water` which is standing at a lower level. The water so taken into the rotor is advanced by. centrifugal force to the periphery thereof where it is discharged rst against the inner wings 22 which are stationary with the stator.' After being broken up into ne particles, the water is then acted upon by the outer Wings 21 which further comminute and break up the water particles. Thus in the condition of a very fine spray the water is discharged from the device.

A spray device having these characteristics may be used with advantage in a humidifierl is taken over a body of water 35 which is contained within a t'ank at the bottom of the cabinet. Over this tankis mounted a spray device which may be the same as the construc-4 tion shown and described in connection with Figs. 1 to 4 inclusive; The bearing box 25 of this sprayer may be connected to one or more struts 36 by which additional support is af-A forded thereto. The inlet pipe 29 is shown as depending intothe water body so as to draw its suppl therefrom. If desired, a thermostatic va ve 37 may be interposed in the feed pipe. A supply pipe 38 is also provided in connection with the tank containing this water, and, if desired, a float valve 39 may be connected therewith to maintain the body of water at a selected level.

Rearwardly of the spray device are water eliminators 40 which may conveniently comprise a series aof closely arranged parallel plates having corrugations or angularities, as shown best in Fig. 5. The moisture-laden airleaving the sprayer is required to pass between these plates which segregate water particles of 'excess size, causing same to drain into the tank at the cabinet bottom. Rearwardly of the water eliminators, I have shown a second heater 41 to which is con-v nected inlet and

outlet pipes

42 and 43, respectively. This heater may be of the same general construction as the' heater 32 al-v readydescribed. s

The rotor shaft .17 extends outwardly from the cabinet through a second housing 45 wherein is mounted a rotary fan 50. The shaft carries near its outer end a pulley 46 over which a driving belt 47 may run to impart motion which is received from a power shaft 48. Extending from the fan housing 45 is a duct 49 whlch leads to one or more places where the-moisture-laden air is to be used.

The humidifier of this invention is advantageous because of the simplicity of itsY construction, and because of the complete used for this purpose may be supplemented,

as necessary, from an outside source, its inflow being controlled by the oat valve 39. The air which is taken into the humidifier is Itreated and conditioned by the several units which act upon it so as to be renvdered suitable, both as to temperature and moisture content, for any selected purpose.
