The central shaft may be driven in anyconvenient manner. In the example shown it is driven bymeans of a worm wheel is gearing with a worm m on a spindle n driven by an electric motor 0. This motor may also be utilized to supply water to the central hollow shaft through a rotary pump p, (Fig. 2) mounted on the motor shaft which pumps the water through a pipe 9 leading to the interior of the step bearing from whence the water passes upward through the shaft 7) to the arms 6 of the sprinkler. After passing through the plates the water drops on to a conical plate I from whence it runs. to the outer edge of the casing where filters, for example gauze strainers 8, may be located either at intervals or continuously around the edge of the plate 7 to remove any impurities deposited on the wet plates from the air and washed off by the water. After pass ing through the filtersthe water accumulates in the lower partof the casing which forms a reservoir and can be drawn therefrom for further use by means of the pump 1), Suitable arrangements, not illustrated and which form no part of the present invention, should beprovided for keeping the level of the water in the lower part of thecasing at a certain minimum height as a considerable amount of the water used will not be available for further; use owing to evaporation. This may take the form of, the well known type of float valve inclosed in a suitable casp ing The upper edge .of the'casing is provided with an adapter 23 connecting it to a duct through which the air or other gas treated passes to wherever it isto be utilized. The air is preferably drawn through the apparatus by suction entering through apertures in the side of the casingabove the level of'the reservoirand passes through the spaces between the plates in the opposite di-, rection to that in which the water is travel ing so that very little water will be entrained compared with what would be c'arriedby.

the air were both air andwater'traveling in the same direction and any that-is entrained will fall back. by gravity before reaching the duct or be depositedon thewallsv of the adapter from whence it will: run down into 7 the casing again. 1

Referring now to 3 each arm's is provided with perforations iii-its lower side and has,feither'secured to it or formed integral with it,'-flanges w and wh -The per-,

forations mayif desired be providedfwith nozzles projecting downward into proximity to the edgesof the plates-. :Theseflanges; are shown as-bein-g 'ofunequal size; the wider flange being Onthere'ar side in the direction of rotationfo'f the arm-.11: The flanges, however, imaybe of the same size oneither side provided that, as shown in the case of flange to, they extend over a number of the spaces formed between the vertical plates f. As-the spaces between the plates are small and the speed of the sprinkler armis low, in some cases the flanges may be omit-ted as the arm itself will act to close a number of the passages for a suflicient time to allow all free water to drop off the plates."

This, as above stated, is to insure that all free water passing through between the plates will have. timeto drop off their lower edges before the air being treated is allowed to pass through them, leaving the plates merely wetted on the surface. For this reason the shape of the arms should substantially conform .to the shape in plan of the platesso that when the plates are curved the arms should be similarly curved and where the plates are radial or. tangential the arm should be radial or tangential.
