ArrARATU's For, SPRAYING LIQUIDS.

Applicationfiled A'p'ri120, 1923: Serial ire/633,376.

This invention relates to an apparatusi'or sprayingliquids. V a a One of the objects of the invention is to provide fluid-operated impelling means for the spraying unit, and to provide .for the spraying of the exhaust fluid from said impelling means by said unit.- t

Numerous other objects of the invention will appear as the description progresses and I, therefore,'de'em it unnecessary to enumerate them here in detail.

In the drawing which illustrates one embodiment of my invention,

Figure 1 is a plan view thereof.

Figure 2 is a vertical section view on line 2-2 of Figure 1.

Figure 3 is an end elevation with portion broken away to show the disposition of the rotor and the exhaust fluid channel, and

Figure 4 is an elevation looking at the opposite end of the mechanism.

The disclosed embodiment of the invention, which is selected merely for the purpose of illustration and to the details of the construction of which I do not intend to be confined, includes a casing 10. In this casing a shaft 11 is supported'by'suitable

bearings

12 and 13. This shaft extends beyond the end or the casing and the bearing member 13 and carries a spraying unit 14 which, in the form illustrated, includes a series of spaced substantial frusto-

comcal plates

15, 16, 17, 18 and 19, which plates are secured together by tie bolts 20, which extend through the spacer collars as shown in Figure 2. The plates 16 19 are provided with aligned central openings 21 which increase in diameter toward the casing 10. The plates are spaced apart so as to provide channels 22 through which the fluid passes from the openings 21. The outermost of these plates 15 is engaged by a flange on the shank 23 which extends axially through the remaining plates and is attached to the end of the shaft 11 by suitable means such as screw threads 23.

While I have illustrated a particular spraying. unit it is to be understood that I contemplate the use, not only of this particular unit, but of various other forms of units,

and I do not wish to confine myself to the use or" the illustrated form.

A fluid actuated rotor 24 having a series of radial pockets 25 is rigid with the shaft 11 and is mounted within the casing 10.

. from the rotor;

In order to impart movement to this rotor by fluid pressure so that the spraying unit 14 will be rotated, I have provided afluid injector 26 (see Figure 3) which projects the fluid tangentially of the rotor and against the pockets at the upper side thereof.

,The casing. 10 iszprovided with a channel 27- for the" "reception of the exhaust fluid This channel merges into a chamber 28 which is provided with an out let 29 at one side of the casing. This outlet discharges into the spraying unit.

The channel 27 is formed between one side 21; the casing 10 and a wall 30 (see Figure which, the rotor 24 operates. A duct 31 communicates with this compartment to carry away that portion of the exhaust fluid which is not discharged into the channel 27 in a manner which is apparent.

It will be seen that when the fluid is pro jected against the pockets 25 of the rotor motion will be imparted to the latter and through its connection with the shaft 11 to the spraying unit 14.

It will also be seen that inasmuch as the pressure fluid is projected tangentially of This wall defines a compartment in the rotor and against the pockets at the upper side thereof, and inasmuch as the wall 30 terminates short of the upper end of the rotor, the greater portion of the exhaust fluid will pass over the upper end of the wall into the channel 27 and thence by gravity tofthe receiving chamber 28. From this chamber the fluid will pass by gravity through the outlet 29 to the spraying unit.

The fluid, therefore, is used, not only to ro- I tate the spraying unit, but also to supply the unit with the fluid to be sprayed.

The amount of fluid supplied to the rotor is usually greater than the amount desired tobe sprayed, and for this reason I divide the casing into the two compartments described, one of which serves as a duct to discharge the fluid in excess of the amount to be sprayed, the other of which is in the form of a passage leading to the spray head.

Because of the arrangement of the rotor, the injection of the fluid at the upper side thereof and the downward course of the channel 27 to the chamber 28 and the outlet 29 the exhaust fluid flows by gravity to the spraying unit and thus no additional energy to supply the spraying unit with fluid is re quired.

While I have described a particular embodiment of my invention I do not Wish to be limited to the details thereof as it is obvious that many changes may be made therein Without exceeding the scope of the claims.

What I claim is: 3 r

1. In a mechanism of the class described in combination with a spray head, a rotor rigid With the same, means for projecting fluid against the rotor, means for conveying a portion of said fluid from the rotor to the spray head and means for conveying the remainder of the fluid from the rotor inclei pendent of the spray head.

for projecting a fluid against said rotor,

said casing having a passage extending from the rotor to the spray head, and a partition in the casing for permitting a portion of the exhaust fluid to pass from the rotor to said passage, said casing having a duct for conveying the remaining fluid therefrom independent of the rotor.

. 3. In a mechanism of the class described, a casing, ashaft mounted in the casing, a rotor Within the casing secured to said shaft, means for delivering fluid to the rotor, and a partition in the casing dividing the exhaust fluid of the rotor into two portions and defining two compartments, each pro- Vided with an outlet for the fluid.

In testimony-whereof, I have signed my name to this specification this 19th day of April, 1923.
