F. H. ELLINGER SPRAYING DEVICE Filed Aug. 22, 1941 ATTORNEYS.

Patented May 9, 1944 UNITED STATES PATENT OFFICE SPRAYING DEVICE Flora H. Ellinger, Chicago,lll. Application August 22, 1941, Serial No. 407,950 r io'claims. (01. 299-34) My present invention relates generally to improvements in cleansing apparatus, and relates more specifically to improvements in the construction and operation of water sprays adapted to produce jets of soapy liquid for washing purposes or jets of clear liquid for rinsing purposes.

Generally defined, an object of the invention is to provide an improved spraying device, especially useful for washing dishes or the like. which is simple in construction and highly emcient in operation.

A more specific object of my invention is to provide a portable spraying device adapted to be associated with any suitable source of liquid supply, so as to effectively produce various desired mixtures of soapy water by direct action of the liquid, whether bar soap, or soap chips, or flake soap is utilized.

A further specific object of the present invention is to provide a spraying device which may be conveniently manipulated and controlled by a novice without danger, when using hot water or other liquid.

A still further specific object of the invention is to provide an improved rigidly constructed spraying device which may be readily dismantled for cleaning, or for soap replacement, and. which may likewise be readily reassembled.

An additional specific object of my invention is to provide a spray head having an independent soap mixing chamber which may be quickly I and automatically drained of soapy liquid, when a spray of soap-free water for rinsing is desired. Another specific object of my invention is'to provide a container for chip or flake soap, especially adapted for use with myimproved spraying device, and which may be readily manufactured from standard stock at low cost.

Still another specific object of the present invention is to provide a spraying unit for washing and rinsing which is highly attractive in appearance, flexible in use, and which maybe manufactured, sold and operated at moderate cost.

These and other specific objects and advantages of my invention will be apparent from the following detailed description.

A clear conception of the several features constituting my present improvement, and of the mode of constructing and of utilizing spray devices built in accordance with my invention, may be had by referring to the drawing accompanying and forming a part of this specification wherein likereference characters designate the same or similar parts in the several views.

Fig. 1 is an approximately central vertical section through the improved spraying device. showing a flake or chip soap container positioned therein; I r

Fig. 2 is a top view of the assemblage with the cover and soap container removed therefrom, a portion having been broken away to more clearly disclose the valve construction; and

Fig. 3 is a central vertical section through an improved soap chip or flake container, showin the same partially filled with soap flakes.

While the invention has been shown herein as being applied to'a portable spraying device especially adapted for dish washing purposes and wherein soap and water are utilized for the cleansing operations, it is not my desire or intent to thereby unnecessarily restrict the scope or utility of the improvement.

Referring to Figs. 1 and 2, the improved spraying device compris'esln general, a cups'haped lower casing 5 having a transverse partition 6 therein. The said partition 6 is formed with a flat bottomed, cup-shaped depression in its central portion and divides the casing 5 into an annular rinse water passage '3' and an upper soap confining chamber 8. The casing 5 also has the upper portion thereof rolled into screw-thread formation 9 with an integral inwardly directed flange I0 formed at its extreme upper edge, and an inverted cupshaped cover ll provided with a screw-thread formation l2 at its lower portion is'adapted for coaction with the threaded casing portion 9 to retain the cover in position. The cover ll also has an inwardly directedflange l3 at its lower end disposable directly above the casing flange l0 and cooperable with a washer M to seal the joint between the flanges I0 and I3 when the cover I I is tightly applied to the casing 5. A handle l5 having a heat insulated gripping portion l5 and being firmly attached to the cover ll serves to manipulate the device when in use, and to also aid in removing and applying the cover H. An upper liquid inlet port I! is formed in the casing 5 above the partition 6 for admitting liquid to the chamber 8. and a lower liquid inlet port l8 likewise formed in the casing 5 below the partition 6 is provided for admitting liquid to the passage. A rotating plug valve I9 is associated with the ports l1. 18 for regulating the flow of liquid thereto.

The casing 5 has a bottom spray plate 20 formed with a multiplicity of small circular openings 2|, radial slots 22 located near the outer edge thereof, and radial slots 23 located about and closely adjacent to its central axis,

'and the partition 6 has a cup-shaped fiat botinlet port I! is provided with a pipe 26 which 1 preferably extends into the soap confining chamber 8 at a tangent thereto, and the cham-' 8 will thoroughly agitate and swirl the soap, whether bar soap or chip or flake soap is being used, and will cause the same to mix with the liquid and to produce suds to a greater or lesser extent depending upon the pressure of the liquid admitted to the chamber 8. The soapy liquid thus produced will be forced from the chamber 8 through the radial slots 25, 23 onto the objects being washed, and should the amount of liquid becomeeexcessive in the chamber 8, the pipe 21 will additionally conduct the overflowliquid to the zone of washing.

The water admitted to the passage I will be distributed throughout said passage and will subber 8 is provided with a vent pipe 21. communieating directly with the ambient atmosphere at sequently be forced through the circular openings 21 and radial slots 22 of the spray plate 28 to intermingle with the soapy liquid from the chama point below the spray plate in order to admit air to and escape of air from the chamber 8, while also facilitating drainage thereof and permitting escape of excess liquid should the amount of liquid in the chamber 8 become too great. w

, The liquid inlet port I! islocatedrabove' the port l8 and is of relatively smalldiameter entering the chamber 8 at an angle, while the liquid inlet port l8 is considerably larger and enters directlyinto the annular passage I. The plug valve H! has a single through passage 28 enlarged at its outlet-end so that it may communicate .with both of the ports l1, l8 and hasa control handle 29 for turning the valve todirect the flow of fresh liquid, supplied froma faucet or the like 'through a flexible hose 30, through thepassage 28 to either boththe port I] and the port l8, or to .the port l8 a1one.-- For enabling the user to ascertain through which port the flow is-being directed; markings 3| may be applied to the handle 29. For convenience and safety, it is preferable to have the handle 15 so positioned on the cover H that it will be located remote from the valve l9 when the device is assembled, and in this position, the hand of the user is farthest away from the source of supply andnot in danger of being burned by hot water admitted to the device, and thespray unit may also be more readily manipulated.

The soap may be inserted into the chamber 8 by first removing the cover H with the aid of the handle l5, and eitherbar soap or chip or factured of a standard tin can and isprovided with aremovable cover 33 and with a multiplicity of openings 34 in the side walls and bottom thereof. Chip or flake soap ;35 maybe introduced into the container 32 upon removal of the cover 33 and the liquid admitted to the chamber 8 flows into and out of the openings 34, agitating the soap and causing suds. When the chamber 8 is emptied, the water remaining in the container 32 drains through the bottom openings 34.

After soap has-been placed in the chamber 8 and the cover H firmly screwed into position, the liquid under pressure maybe supplied from the source thereby forcing liquidthrough the hose 30 and valve passage 28. If soapy water for washing purposes is desired, the valve handle 29 may be properly positioned to permit flow of the liquidv fromthe passage28 to the port I! into the chamber 8 through the pipe '26 and directly into the annular passage] throughthe port l8. The liquid admitted tangentially to the chamber her 8 before reaching the zone of washing. The

formation of the slots and circular openings insures thorough mixing and intermingling of the jets issuing therefrom, and thus insures constant production of the proper Washing mixture.

. After the washing operation has been completed, the valve [9 may be turned to rinse thereby cutting off the flow'of liquid to the chamber 8 andadmitting fresh liquid only to the annular passage 1 from which'jets of clear liquid are directed through the openings 2| and slots 22 to the objects for rinsing. When the liquid supply is cut off from the chamber 8, air is admitted to this chamber through the vent pipe 21, thus permitting free escape of the liquid from the chamber 8 through the slots 25, 23 by gravity.

From the foregoing detailed description it will be apparent that my presentinvention provides an improved portable. spraying device which is simple, compact, and durable in construction, and which is moreover highlyelficient and universal in use. The improved spraying device may be readily dismantled and assembled and may be utilized with soap in bar form as well as in chip or flake form, and any suitable source of pressure supply may be used. Most of the parts may be readily manufactured of sheet metal stampings, and the chip soap container may be made of a standard tin can with the aid of a punch. The device may be readily and safely manipulated by means of the handle I6 located remote from the source of hot water supply, and this handle is preferably hook-shaped to permit suspension from a point near asink or the like.

All parts of the assemblage are readily accessible for, cleaning, inspection, and adjustment; and the device may be freely converted from washing with a soapy mixture to rinsing with a clear soapfree liquid, and vice versa, The device is attractive in appearance, can be manufactured and sold at moderate cost, and has proven highly successful in actual use. The passage 28 may also obviously be so formed as to permit flow of liquid from the hose 30 directly to the chamber 8 independently of the passage.
