This invention relates devices for conthe motor to the Vibration of the ditioning air in rooms, by circulating the air latter is further dampened by a sultable hn and by reason of such circulation purifying ing L extending about the mtenorof the the air and also cooling or warm it as well as altering the humidity thereo either to an increased or lessened degree as governed by any particular installation.

The main object of my-invention is tojprovide a self-contained, compact and unitary ap artus of this character which may be eit er made as a ortable unit or a permanent installation, y means of which the air into .said 0 the motor but inside the 8. A fan is secured to'this disc which is in the form of a plurality of blades 9 extendcasing.

The motor is not as large in diameter as the opening 3 sothat air can readily flow ning all about the motor. Mounted on the motor shaft 7 in front of ing from the periphe of the disc over the will be thus conditioned in a very eflicient motor toward the bac of the casin The manner and at a minimum of operating expense.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingliy eifective for the purpose for which it is eslgned.

These ob ects I accomplish by means of casing'froman overl parts as.wil1' fully appear by a perusal of the following speci cation and dams. In the drawing similar characters of reference indicate corresponding parts inthe several views:

Fig. 1 is a front elevation of the apparatus.

'Fi 2 is a transverse vertical'section on the hne 2-2 of Fig. 1.

Fig 3 is a sectional elevation on the line 3-3ofFig.2. Y

Fig. 4 is a fragmentary view showing the means for driving the perforated cone.

Referring now more particularly to the characters of reference on the drawing, the case 1 of the apparatus is preferably flat on the bottom and curved around the top. It is provided in its front face with a circular air discharging opening 2 and ,at the back with 'a relatively small intake opening 3 concentric with the opening 2 and surrounded with an inwardly pro ecting flan e 4. An electric motor '5 is disposed in 'tl ie casing concentric with the openings and is lower isasoliddisc apgingrgelation to the such structure and relative arrangement of flange 4 to adjacent e nt opening 2 is acperforated frusto-conical air conduit 10" wh1 is open on both ends and lined with water absorbing fabric'll. The large end of this conduit is at the front'and such end is substantially the same diameter as the openinfi 2. The conduit'is reinforced against 00 apse b outwardly projecting flanges .12 at its en It is supported in concentric relation to the motor and other parts by grooved sheaves 13 mounted in the casing in circumferentially spaced relation and engaging the front flange 12. One of said sheaves has a relativel large drive pulley 14 associated therewi wh'ch'is connected indrivingrelation with t 0 motor shaft in front of the disc 8 by a belt or similar drive 15. The fan and conduit are therefore driven in opposite directions and the latter turns at a slower speed than the fan. a I

The bottom portion of the casing is water-tight so as to form a tank 16 for the reception of a sup ly of water into which the lower portion 0 the conduit, di To prevent the lower fan bladgg from dip- 17 immediately above and parallel to the portion of the conduit. This late extends am the front of the casing a ut the opening2tothebackflange4andhaswaping 1nto the water I provide a guard plate tar-tight connection therewith the sides of the late being at a height equal to that of the rotation of the latter the flaps successively dip into the water and the lining 11 is ke t in a moist condition even though the supp y of water in the tank is depleted so that the conduit itself will not dip into the same. y

In operation the air to be conditioned is drawn in through the intake opening 3 and by the centrifugal action of the fan blades is thrown against the wet linin of the conduit and .thence out through the discharge opening 2 into the room. Any dust etc. in t e air as drawn in is thrown against the wet lining and adheres thereto, and will be carried around until it is washed oif by the water in the bottom tank. The reverse movement of the fan and conduit relative to each other causes the air passin therebetween to be agitated and aids in t e separation of the dust and other foreign matter from the air and consequently enhances the purifying action.

Also the air circulating through the device and coming constantly in contact with the wet lining will be humidified. If a disinfectant is added to the water in the tank the air will also be disinfected. As the fabric lining is being continually immersed in the water there is no tendency for any dissolved salts in the water tohcrystallize on the lining and im air its efliciency. Evaporation of water rom the revolving conduit by the rapid passage of air therethrough naturally'sets up a coolin effect on the am This may be increased i desired by placing a cooling coil arrangement 19 in the bottom of the tank and connecting said coil to a refrigeratinglunit or the like so as to chill the water in t e tank to whatever temperature may be desired. If the coil' is connected to a heating device the water in the tank will be heated and the air as circulated'will be corres ondingly warmed.

, ince the humidifying action varies with the temperature it will be lessened the cooler the water is kept and increased according as the heat of the water is increased. When the device is constructed as a portable unit-the tank is re-filled with water as needed but in a permanent installation said tank may of course be connected to a constant source of I water supply to automatically maintain the water in t e tank at-a predetermined level. From the foregoingl description it will be readily seen that I ave roduced such a device as substantiall fu s the objects of the invention as set orth herein.

While this specification sets forth in detail the present and preferred construction tions from such detail may be resorted to as do not form a departure from the spirit of the invention, as efined by-the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:
