HUMIDIFIER.

Application led December 24, 1925.` Serial No. 77,617.

My invention-relates to Vimprovements in devices for cooling or humidifying air, the principal object being to provide a new and improved device of this character in which :i novel provision is made for moistening air which is induced to flow through a casing, by an electric fan or some equivalent means.

A still further object of the invention is to make provision for supplying cooling air to the fan motor, from the exterierfof the humidifying casing, so that said motor will be kept cool and 'dry and cannot be affected by the moisture of the air within the casing. f With the'foregoing and minor objects in View, the invention resides in the novel subject matter'` hereinafter describedV and claimed,'the description being supplemented bythe accompanying drawings.

f Figure 1 is a sideelevation of a humidifier constructed in accordance with myinvention.

Figure 2 is an end elevation.

Figure 3 is an enlarged vertical longitudinal sectional view asindicated by line 8-3 of`Fig.2. Y .Y

Figure 4 is a vertical transverse section en line 419-4 of Fig. 3. Figure 5 is a horizontal sectional view as vindicatedby line 5-5 of Fig. 3. j j

Figure is a perspective view of a frame structureiused'to` support one of the air mois tening, absorbentmembers.

" The form of construction selected for illustration in the present applicationl maybe considered as preferred, with the understanding however that within the scope of the invention as claimed, variations may be inade. Y

The numeral 7 desigpatesa vertically disfposed casing prefera ly formed of sheet .metal, saidcasing being closed at its bottom 'asiat' 8, being formed with an arched top 9, and having a four-sided wall 10. The lower portion of this wall is formed with air inlet perforations 11 and Vsaid lower portion is equipped with aperforated door 12 forgiving access to certain interior parts, permit ting removal and reinsertion of such parts. The upper portion of the side wall is formed with a relatively large air outlet 'opening 13 which is `preferably surrounded by an outwardly projecting annular' flange 1,4. Directly opposite this opening 13, is a comparatively small opening 15, through the casing wall'10, for a purpose to appear.

"Disposedwithin the confines of the flange y 14,is a Vfan 16 which isdetachably connected by a set screw or the4 like 17 with the shaft of an electric motor 18, the latterbeing suitably supported in the upper portion ofthe casing 7. In thecon'struction disclosed, the motor 18 is provided with `upstanding ears 19 secured bya bolt 20 to a pair of plates 2l which project vertically downward froml the casing top 9. Between these plates, I posi.

tion the current conducting wires 22 for the motor, said lwires being connected with an appropriate rheostat or other formof switch 28. Vhen the fan 1G is driven, it induces entrance of air into the casing'` through the perforated lower portion thereof and causes discharge of such air through the opening 13 and provision is made for moisteningths air. As this humidified airlwould have an injurious effect upon the motor 18, I do not permit itto pass through the motor casing. Instead, I. provide a horizontall disposed air-conducting tube 24. which lea s from the opening to the inner end of the motor 18, the inner end of said tube preferablysurrounding the motor casing and Vbeing notched as at to receive the usualbrushholders and adjusters 26.

Within the casing 7, between the air inlet and outlet means, I provide a water tou h 27, this troughbeing preferably formediy extending a horizontal flange 28 inwardly from the casing wall 10, and providing the inner edge of this iange with an upstanding annular flange 29. Anothery water container, in the form of a pan 30, is provided in the lower portion of the casing 7 the latter pref- Jerablyhaving perforated supports 31 for said pan. The supports 31 are preferably in .the form of two right angular metal strips arranged across the bottom 8 of Vthe casing `and adjacent two opposite sides thereof asy shown in cross section in Fig. 3 and in dotted `lines in Fig. 5 and one of which is shown in side elevation in Fig. 4, the perforations being in the vertical sides of the supports as shown at 31a. A reticulate` sleeve 32 of absorbent material, passes over the vertical flange 29 and has `its upper end extended downwardly into the watertrough 27, this upper end of the sleeve being preferably connected to a wire hoop 33. This hoop snugly surrounds the flange 27 and holds the sleeve in place, and if desired, said hoop may be split to permit of its being readily discon- Ynect'ed'from the flange. 29. The lower end e i Y thisis preferably done by disconnecting or ldetachinga fan guard 37 which isengaged" normally with the flange 14, then removing t the fan 16 from thev motor shaft, inserting rosive wire.

of the sleeve 32 is 'positioned in the water pan and it will be obvious that the water from this pan and from the trough 27 will keep said sleeve effectively moistened, so that all air passing through it will be thoroughly humidified.

Ipreferably Vprovide additional air mois- Y tening means around the sleeve. 32, said the bottoml of the pan 30, soV as to be effectivelyrmoistened by fthe Y water from the latter. The air entering the casing may readily pass" through the strands of this absorbent. wall and must vthen pass through thereticulate;sleeve 32, before it can be discharged from the casing by the fan/16. In traveling linthis manner, the air is ad.- vantageousb7 moistened and cooled, so that higlrefiiciency can be obtained from the den Inorder tofillvthepan 30, it is simply neeessaryto open the door 12, and access to the opening 13, or by withdrawing the tube 24 and pouring water into said trough, from la suitable# container `inserted through the until the latter will'clearthe pan 30, then duce an unusually casmg.-

opening' Whenever the moistening means should be-removed from the casing,

one hand through the-'opening 13 and. lifting the sleeve 32' and the moistener 34--35-36,

removing the latter through the open door 12 and later removing saidl moistening dejvicethrough thesame opening; The hoop may .bev disengaged from the flange or wall 29 and withdrawn through the opening 13,- with the sleeve Y The lower edge of .theopening 13 is preferably straight as shown in Fig2 andis lconsiderably above the water level of the trough 27,1as will be clear from Fig. 3. There is thus no dangerof the yfan 16 suckingv ordrawing water directly from this trough. and this is rather important as positioning of the fan inthe flange 14, causes it to prostrong suction through the Whenthe fan16 is in motion air is drawn into the lower port-ion of the casing through the air inlets 11 and iipvvardly`-between the 1 absorbent w'rappings y36 and` through Vthe retioulate sleeve 32 into the upper portion of the casing from whichv itkk is disehar ed' through the outlet openingg13` in a umidified condition. l the supports 31 permit the air drawn vthrough the lower perforations 11 ofthe sides of the casing adjacent to the supports to circulate freely beneath the panu30and pass upwardly betweenthe pan andgthe easing. y v y Excellent results-have been obtained from the details of constructionfherein disclosed.

They are therefore preferably followed,but`

ywithin the scope of the invention asclaimed,

numerous variations'rnay be made.`
