Application July 18, 1933, ScrialNo. 680,928

13 Claims. .(Cl. 299-83) My invention relates to spray devices of the type employed for emitting an aqueous suspension or solution of a chemical substance, such as, a

disinfectant, an insecticide, a water color etc.

An object of my invention is the provision of a spray device of the character described which can be attached to the ordinary garden hose and in which the water, in approaching the nozzle, rotates an element composed of the substance to be used in the spray, thereby forming a solution or suspension of that substance depending upon its solubility in water.

A further object of my invention is the provision in such a device of a rotatable element of such configuration that the solution or suspension formed by the passage of water thereover will be of substantially uniform concentration until the substance is entirely consumed.

An additional object of my invention is to so 20- construct the rotatable chemical element that the breaking off of large pieces thereof and the consequent clogging of the spray nozzle will be practically eliminated and that the rotation t r bedded in -the-surface of this core and in the thereof will be made certain. I

Still another object of my invention is the provision of means in a device of the character described for preventing the clogging of the spray nozzle by any small lumps of chemical substance which might become separated from'the rotatable r need not be normal to the core, but can be set element. Further objects and advantages of my invention will appear from the following description of the accompanying drawing in which:

Fig. 1 is a plan View of my spray devicewith l filling the mold of a paste of the desired chemical portions thereof in section.

Fig. 2 is a side elevation of my device with the cover separated therefrom and partly in section for the sake of clearness.

Fig. 3 is a section taken through the axis of i 40 the framework of the rotatable element.

Fig. 4 is a plan view of the framework of the rotatable element and Fig. 5 is a plan view of a rotatable element of different configuration. Referring to the drawing in detail, 1 represents a circular casing having a spindle 2 mounted at its center, a water inlet 3 arranged to direct a stream of water in a direction chordal to the circular casing 1, said inlet being supplied with water by a pipe 4 which has a coupling nut 5 to connect it with an ordinary garden hose and a stop cock 6 for turning the water on and off. Any conventional type of valve can be employed in place of stop cock 6. A handle 7 ofany suitable configuration is arranged between the pipe 4 and the casing 1.

Casing 1 has a water outlet 8 at apoint more than 90 removed from the water inlet. The longitudinal axis of this water outlet is normal to the casing 1. Mounted in the outlet 8 in a plane spaced from the circumference of the casing 1 is a'screen 12. The space between the screen and the interior of the casing 1 forms a chamber wherein any particles of chemical which may break away from the paddle wheel can be retained out of the path of travel of the paddle wheel until they are broken up or dissolved by the water. The screen prevents these particles from entering into and clogging the nozzle 14 which may be of any conventional type and which is attached to a sleeve 13 mounted on the outlet 8.

Mounted on the spindle 2 is a rotatable element 9 of the chemical substance to be introduced into the waterJ This element, in its preferred form, has the-shape of a paddle wheel.

-Thiselement has a metal core 10, preferably made at an angle thereto on, if desired. H

The rotatable element of chemical substance is generally molded. This i'saccomplished by or arranged helically theresubstance, such as, arsenate of lead or a mixture of arsenate of lead and sulphate of nicotine or any of the common fertilizers, such as, mixed nitrates and phosphates of the alkali metals and ammonia or any water color, kalsomine or whiting etc. The framework composed of core 10 and vanes 11 is immersed in the paste centrally of the mold and the paste is permitted to dry thereon. The moulding is facilitated by the employment of pressure. I i

The circular casing 1 is provided with a cover 15, which carries'a glass plate 16, which makes it possible to tell when the chemical substance on the rotatable element is" consumed.

In the modification shown in Fig. 5 the vanes of the paddle wheel, instead of being fiat pieces of metal, are constructed in the form of cages 1'7. The sides of these cages are made of 'a sheet of perforated metal or screen which is bent in the manner shown and the ends of which are brought together andinserted in the soft metal core 18.

-The bottoms of the cages are likewise made of perforated metal or screen and can be made integral with the sides. Each cage carries a block of chemical substance. When this construction is employed the paddle wheel can be made as a fixed element in the spray device, it being necessary only to replace the blocks of chemical substance. The tops of the cages are open, the blocks, being prevented from leaving the cages by the cover plate 16.

It is to be understood that there is no limitation'with regard to the material of which the rotatable chemical element is to be made. Any

material which is to be employed in an aqueous spray and which dissolves in or suspends in I element.

water can be utilized.

It is to be further understood that there is combination, a mixing chamber, a water inlet in no restriction upon the configuration of ,the rotatable element except that it must be such that it presents substantially the same surfaee at all stages of wear. In'additiomit must be borne in'mind that regardless of what type of device is used, the inlet orifice must have a smaller diameter than the outlet orifice. Of course, the sizeof the outlet orifice can be regulated by adjustmentof the nozzle. As the size of the outlet orifice approaches the size of the inlet orifice the spray becomes finer, but the distance it will travel becomes smaller. Conversely, as the outlet orifice becomes larger, the distance travelled bythe spray becomes larger.

Having thus described the nature and objects of my invention and illustrated preferred embodiments thereof, which embodiments are to be taken as illustrative rather than limitative, what I claim as new and useful and desire to secure by Letters Patent is: v V
