While my invention has been shown and described herein as being specifically applied toa spray head for dish washing use, it is not the intent to thereby unnecessarily limit the scope of the invention or the usesto which it may be applied.

The present invention comprises generally the provision of a portable spray head assemblage, and a plurality of accessories such as a liquid soap dispenser, a bar or flake soap dispenser, and a brush assemblage, which may be utilized either individually or combined, in conjunction with the spray head assembly.

Referring to Figs. 1, 2 and 3 of the drawing, the improved spray head assemblage shown therein comprises in general, an annular spray head or nozzle Iii attached to one end of a flexible tube II by means of a nipple l2, tube ll being formed for attachment to a faucet by means of an elastic coupling l3 secured to the opposite end thereof. The annular nozzle It is provided with a peripheral recess l4 and a depending annular lip l5 having alternately arranged circular spray holes l6 and elongated spray slots ll, circular spray holes l8 also being provided in the convex lower face of the nozzle [0 within the lip IS. The top wall of the nozzle l0 constitutes a dish-shaped plate l9 formed with a conical thimble 20 providing a. tapered valve seat located centrally thereof and penetrating the liquid chamber of the spray head ID.

The liquid soap container consists of an inverted cup-shaped housing 2| having a central sleeve 22 at the top thereof and being rigidly secured as by soldering to the head or nozzle l and constituting a suitable gripping handle for the portable assemblage. As shown in Fig. 1, a hollow tube 23 having an externally threaded portion 24 for cooperation with internal threads in the sleeve 22 is disposed centrally within the housing 2|, and the upper end of the tube 23 which extends above the housing 2|, is provided with a closure plug 25 and an actuating ring 26 having ears thereon, the ring being rigidly secured to the tube 23 by means of a locking pin 21. As shown in Fig. 6 the tube 23' is slidable in the sleeve 22 and is pressed downwardly by a spring 24, the tube 23' being provided with an integral grip ring 26' and with a lug 21' cooperable with a notch and with the top rim of the sleeve 22. The lower end of the tube 23 is provided with a solid tapered closure plug 28 adapted for snug engagement with the valve seat 26 in the plate l9, and downwardly directed angular openings 29 extend through the medial portion of the wall of the tube 23. The valve seat 20 connects centrally with radially extending conduits 30 secured to the convex lower face of nozzle I0 and having perforations 3| therein. However, these conduits need not be radially disposed nor need they be located on the outer lower face of the spray head; but they may be of various shapes such as a single spiral conduit and may be secured to the lower face of the spray head on the interior thereof. Convenient markings 32 may be provided on the top of housing 2| adjacent the ring 26 and a pointer 33 may be formed on the ring 26 for indicating the open and closed position of the valve.

If it is desired to utilize bar or flake soap with the assemblage rather than liquid soap, an attachment such as shown in Fig. 4 may be readily furnished. The bar or flake soap attachment comprises a wire cage or basket 34 having upwardly extending resilient and laterally curved arms 35 adapted to be snapped about the nozzle I0 within the peripheral recess l4 and be retained thereby. The case 34 may be provided with a removable cover or door 36 for insertion of the soap 3'! into the cage, and this entire attachment may be readily manufactured of perforated sheet metal instead of wire.

A brush attachment as shown in Figs. 1 and. 2 may also be provided for use with the spray head either independently of the soap assemblages or in combination therewith. The brush consists of a resilient and stretchable annular band 38 adapted to be stretched over and seated within the peripheral recess I4 of the spray head In to be retained thereon, and downwardly directed bristles 39 are carried by the band 38 and surround the zone of action of the jets delivered from holes I6 and slots IT. The band 38 preferably has a thickened portion 46 carrying laterally directed bristles 4| adapted for reaching into and cleaning corners of the dishes, and these bristles 4| may obviously be located at any desired place around the spray head. Obviously the band. 36 may be provided in any width and may be utilized with the bar soap attachment shown in Fig. 4 as well as with liquid soap.

Fig. shows an enlarged cross-section of one of the spray slots I1 formed in the lip I5 of the spray nozzle. These slots are preferably formed with a sharp-edged tool so that a relatively long and narrow opening will be provided which will direct a comparatively narrow and long impinging jet in a desired direction. Several of these slots |'I are preferably located along the lip I5 at the outer ends of and facing the conduits 30 to direct flat jets which impinge the soap dripping from the perforations 3| in conduits 30. Other slots Il may also be located on the lip I5 and are so directed as to deliver jets which impinge the jets delivered from holes I6, I8 of the spray nozzle within the zone of action of the soap mixing. The force and mixture of these several impinging jets with the soap and spray from holes I6, I6 within a limited zone creates abundant lather for washing. When bar or flake soap is used with the assemblage, the jets delivered from slots H are directed upon the soap in cage 34 and impinge the spray delivered from holes I6, I8, to create lather in substantially the same manner as with liquid soap.

In normal operation of the assemblage, coupling I3 is attached to a hot water faucet and water is passed through tube II and nipple 2 into the spray head I0. As spray head becomes filled with water, the pressure created therein forces jets of water through the holes I6, I8 and slots H with considerable force, the jets delivered in various directions within the zone of action by slots |I impinging the jets from holes I6, I6.

The soap housing 2| is filled with liquid soap by removing the closure plug 25 from the tube 23, 23 and pouring soap therein. The soap is admitted to housing 2| by means of annular perforations 29 in the tube 23, and closure plug 25 may then be replaced in the tube. The ring 26, 26' rigidly secured to the tube may then be actuated in the proper direction, as indicated by the markings 32, to move the tube 23 upwardly within the housing either by cooperation of the threads in sleeve 22 with the threaded portion 24 of the tube in Fig. 1, or by merely lifting and rotating the tube 23' in Fig. 6. This upward movement of the tube removes the tapered closure plug 28 from its previous snug engagement with valve seat 20 in plate I9 and permits soap from housing 2| to flow slowly through the thimble 20 into the central portion of conduit 30 from which the soap drips through perforations 3| into the zone of action of the spray delivered by holes I6, I8 and is forcefully impinged by the jets delivered by slots I'I. Plate I9 is preferably dish-shaped with valve seat 20 located centrally therein because the soap is delivered from the housing through the valve and conduits by gravity, and the provision of a dish-shaped plate with the valve located in the center permits utilization of all of the liquid soap in the housing due to drainage toward the lower central portion and provides for effective feeding of the soap through the valve to the conduits.

When the bar or flake soap appliance shown in Fig. 4 is utilized with the assemblage, the jets delivered by holes I6, |8 are directed against and about the soap, and cross jets from the slots Il strike against the soap and the other jets to for a lather. When this assemblage is utilized it is customary to have the closure plug 28 in snug engagement with the valve seat 20 to stop the flow of liquid soap. When the brush shown in Figs. 1 and 2 is utilized either with or without the soap units it is preferably positioned on the spray head as shown, with the bristles 39 pointing in a downwardly directed position surrounding the zone of action to aid in cleaning corners of the objects being washed. The thickened toe portion 45 provided with laterally projecting bristles 4! is especially useful for reaching into inaccessible corners for cleaning the same.

From the foregoing detailed description it will be apparent that my present invention contemplates the provision of a simple but highly efiicient dish washing assemblage which may be conveniently and economically manufactured of sheet metal with the aid of punches and dies and which is durable and compact in construction. The soap housing is so shaped as to form a convenient gripping handle for the appliance without endangering the operator, and the formation of the spray head is such that bar or flake soap attachments as well as a brush may readily be utilized. The formation of the slots and holes in the nozzle provide for impingement of the jets against each other and against the soap within a relatively confined zone of action, thus insuring provision of a constantly flowing lather to the objects being washed. It should further be noted that fresh soap and water is constantly being supplied for the washing operation by the present assemblage.

It should be understood that it is not desired to limit this invention to the exact details of construction or the precise mode of use, herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
