In air cleaning processes, the air is blown or drawn through a spray of water. In order to obtain the most eiicient results it is desirable that the water be very finely divided and be distributed over a suflicient area to avoid the necessity of causing the air to flow at too high a speed. One form of apparatus that'is used for producing a spray con- A sists of a revolving table having along the periphery a fence-like arrangement composed of long pins, the water being discharged upon the center of the table from a nozzle and being thrown outwardly by centrifugal force and being finally broken up by the pins as it leaves the table. There are several objections to this old form of apparatus. ISince the table as a whole revolves, the adhesion between the water and the table causes the layer of water next to the table to revolve at the same speed as the latter, so that it simply flows oft' the edge of the table between the pins and is not broken up. `Furthermore, the control of the flow of water to the table is through a valve that cuts down Vthe pressure as the flow is reduced, thus changing the characteristics of the spraying operation.

Viewed in a specific aspect, the present invention may be said to have for its objects to 20 improve the aforesaid apparatus so as to insure that none of the water reaching the pins will be moving angularly with the pins but in a radial direction, so that -all of the water will be beaten by the pins and be transformed into a fine spray, and permit the rate of flow of the water to be varied without adecting its radial speed of travel. A further specific object is te permit ready adjustment to beA made to*- vary the line of contact between what may be termed the sheet of water and the pins.

Broadly speaking, the present invention may be said to have for its object to produce a simpleand novel mechanism for efficiently transforming a body` of liquid into a fine spray.

The various featurejof novelty whereby my invention is characterized will hereinafter be pointed outwithparticularity in the claims; but, for-a full'understandingv of my invention and of its objects and advantages, reference may be had to the following Adetailed description taken; in connection with the accompanying drawing, wherein:

Figure 1 is an elevation of an apparatus or 55 mechanism arranged in accordance with the present invention, a fragment of a supporting and enclosing casing being shown in section; Fig. Q. is a view on an enlarged scale, partly in side elevation and partly in sec 60 tion of the immediate liquid delivering and spraying means; and Fig. 3 is a section taken approximately on line 3 3 of Fig. 2.

Referring to the drawing, 1 represents a vertical nozzle' adj ustably connected to a de- 65 livery pipe 2, conveniently by being screwed into the latter and held in any position of adjustment by means of a locknut 3. Below the nozzle is a cone-shaped table 4 whose central axis is vertical and coincident with the long axis of the nozzle. The table may conveniently be supported from the nozzle as,

for example, by means of arms 5 extending upwardly from the periphery thereof to a collar G screwed upon the nozzle. A locknut 7 serves to holdthe collar in any position into which .itmay be brought. The apex of the conical table projects into or may beL caused nto project into the nozzle. By rotating the I table, to move it up or down, the effective discharge opening of the nozzle may be varied; the table actingas a valve to reduce or increase the area of the discharge opening. Therefore the rate of flow of water from the nozzle may be varied by increasing or decreasing the size of the outlet for the water, without affecting the pressure.

Surrounding the table is an annular row of pins 8 arranged in the form of a frustum of an inverted cone whosezcentral axis is coj incident with thatof the table. These pins may be fixed upon a suitable ring or spider 9 mounted on the upper endof a shaft 10 driven by an electric motor 11 or other suitable powerdevice. There is no mechanical connection between the table and the pins or their s upports, so that .the pins may be revolved about the@ table while the latter remains stationary-.-

Assuming that water or other liquid is 10b p is revolving,

will iow in all the latter attempts to pass flowing out of the nozzle and thatthe shaft it will be seen that the liquid directions toward the periphery of the table, leaving the table in a substantially radial direction. The force with which the liquid is discharged is suicient to carry it into the path of the revolving pins which therefore strike the liquid sharply as between them, and breaks the liquid into a ine spray.

The nozzle and the table may be moved as a unit in the vertical direction so as to raise or lower the table without affecting the rate of flow of liquid from the nozzle; thereby permitting theliquid iiowing from the table to strike the pins at different elevations to secure the most effective production and distribution of the'spray. Furthermore, because the nozzle and the table may be adjusted as a unit in the variation in the rate of flow from the nozzle may be brought about without varying the position of the table relatively to the beater.

While I have illustrated andH described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions-of my invention constituting the .appended claims.
