J- E. CLARK ET AL HUMIDIFIER Filed Nov. 16. 1925 INVENTORS A ORNE Y Patented Dec. 13, 1927.

1 UNITED 1 STATES PATENT "OFFICE- mains E. CLARK nn THOMAS E. CLARK, or DETROIT, MICHIGAN.

,HUMIDIFIER- Application filed November in attaching an electric heater below the fan so that the humid air may be heated. It also consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims. 7

In the drawing, Fig. 1 is an elevation of a device embodying this novel combined humidifier and heater. Fig. 2 is a bottom plan of heater. Fig. 3 is an elevation of one of the wire-supporting arms of the heater on a larger scale. Fig. 4 is a section on the line 1- of Fig. 3. Fig. 5 is a section of'the trough for holding the. liquid to be. evaporated.

Similar reference characters refer to like parts throughout the several views.

The construction of the electric motor connections, of the bell-shaped housing and of the means for supporting the lamp socket from the housing form no part of the present an invention, as they are described and shown in the Thomas E. Clark application, Serial Number 330,282, filed October 13, 1919, and any other-suitable motor installation may be employed. The present drawing, therefore, 5 shows merely the bell-shaped housing 1 having the apertures 2 and the rounded lower edge 3; a frame 4 of wires extending down from the edge 3 of the housing and supporting the ordinary lamp socket 5; and the fan 6 mounted on the lower end of a vertical shaft 11 of an electric motor which is not shown in the present drawing. p

A jacket 7 of open knitted, netted or woven fabric is placed over the apertures 2 in the flaring portion of the housing land may be held in position thereon by the ring 8. A circular trough '9 maybe mounted on the edge of the housing, as shown in Fig; 5, and provided with fingers 10 which extend into apertures 2 and support the wicking' 12 which contacts with the lower edge of the jacket 7. The liquid to be evaporated may be poureddirectly onto the jacket 7 or into the trough 9 from which it will pass to all parts of the jacket through capillary action.

lVhe'n the fan 6 causes a movement of air through'the jacket, the liquid held thereby willbe evaporated to humidify the air thus moving through. Thisliquid may be a perfume, a disinfectant or purely med cinal such as one which is effective for the treat ment ofscalp troubles, in which case the patient may be seated directly below the fan and his or her hair manipulated to permit the humid air reaching every part thereof.

mounted on the plug 15 preferably by securing the ends of the strips 18 thereto. A spiral i 19 of high resistance wire is mounted inthe holes 17 of the mica and a screen 20 of any plesired character may be mounted below the ieater.

The device is peculiarly efiective for changing and charging the air of large assembly rooms, theaters and the like wher large numbers of persons congregate. The

air is caused to circulate rapidly and each portion that passes through the jacket leaves behind the dustwhich it carries so that the air soon becomes free from physical impurities.

Any other type of small electric heater may be mounted below the fan 6 and the screen 20 may be omitted, if desired. Pressing the button22 causes the fan to rotate and a stream of properly charged air to be forced down from the housing. By pulling the cord 23 current is caused to flow through the heating spiral 19, over which the current of air passes from the fan and is warmed thereby.

'It is evident that the heater may be omitted or removed when desired. The details and proportions of the variou parts may all be changed by those skilled in the art without departing from the spirit of our invention as set forth in the following claims. v

We claim 7 I y 1. In combination, a substantially bellshaped housing having apertures in its flaring portion, and a trough secured to the edge of the flaring portion, a jacket of fabric mounted over the apertures in said flaring portion and having its edge extending into said trough, means in the trough to receive 10 its rim, a jacket of fabric mounted over said apertures and extending to said liquid revolving means to receive llqllld therefrom, a

rotatable shaft positioned axially of said housing, a fan. attached to said shaft at the open end of said housing and adapted to draw air through said apertures and fabric, and an electric heater mounted in the path of the air moved hythe fan.
