'lCIa'im. 1 a My invention relates to a dish washer of the kind which can be installed on an ordinary kitchen faucet.

My improved dish washer includes .a container for bar soap and -a valve for controlling: flow of water-in such :mannerthat in one position of the .valve, water :will be directedagainst and around the soap and the ends conveyed from thence to a nozzle from which the soapy water -can" be directed .in needle-like streams to .the

chamber maybe drained.

.I: also show-a modified form-10f structure for directing the.water against the soap.

With: these 'andwother. objects in view, any invention consists in .the construction, arrangement and combination of the various parts :of my device whereby the objects COZlllQlIlDkttBdl-fil attained, ask-hereinafter .more fullyset forth, pointed out in the #claim andlillustrated inithe accompanying drawings, wherein: Figure? 1 is'a front elevationofthe dish washer embodying my invention mounted on a faucet.

Figure 1611s a vertical sectional view of a slight- =ly modified form .of my .dish washer illustrating another way-of directing the water .to the soap. Figure 157 is an enlarged vertical section of the nozzle for directing water against the soap, in theformof the device shown-in Figurelfi, taken ,ontheli-ne.ll.l l of Figure 16. .In the drawings herewith I have used the reference numeral ID to. indicate an ordinary swinging faucet of the kind commonly found in'kitchens and in connection with which my dish washer may be used.

The dish washer includes a soap container, indicated as a whole at l2 in Figurel, and comprised of upper and lower members-l5 and I4 screwed togetherat I i-as shown in Figure 2. A suitable gasket 18 is provided to prevent leakage from the container l2. The lower part I4 of the containerhas anannular horizontal shoulder 20 -at"its bottom, as shown+in Figures 2 and 5. .Inwardly from .the shoulder is a circular depression 22, with a concave bottom. Asu'bstantially round platen is. supported on thelbottom' portion .2-2.-andrspaced. above it by studs 26.

Thestop-zmember l5 of'the container I2 has an annular flange 23, Figures 2 and 5'; spaced from the wallrof the lower member 'l 4. and terminating .a veryshort-distance above. the annular shoulder .28.

Avbar of soap may be placed onthe plate 24.

Secured to-the underside" of-the member M by bolts 32--is atightly-seated sleeve *36 having a bore in which a valve' casing '35 is :rotatably mounted.v :Within thesaidcasing there is a tapered valve 31 having-.thestem 38 on which is the controllinghandle 39.

01h the :'-f0rm-.0f myeinvention now being described, the valve is planed to have four positions, to-wit,;=.an1.ofP-position, a sudsing'positi0n, a rinsing position and a drain position. @Theqwat er supply pipe to the valve is indicated at. lt'eommunicates with a passage =42 through the valve casingand sleeveet, leading to the valve 3?. The valve 31 has a transverse passage M, Figure 5, leading through it. There is a passagew4'6 through the "wall of the sleeve 36 and through-the wall ofthe casing '35, directly oppo- "sitethe passage 42.-;-In,.one'position of the valve, the .passa'ge ifi registersiwiththe passages 42 and 46. The-passage t6 communicates with a passage "48; in the lower container member 14 which opens into the annularpassage 59 formed around theflange 28.

- Theivalve casing '35 and sleeve '36 have 'apassage 52 which registers with a passage 54at the opposite-sides-:,of the :sleeve, 35 and casingt35 and .with'a passage 55.:in the container :member 14.,

the pipe 68.

3 leading from the bottom portion 22. In the valve 31 is a cross passage 56 parallel with the passage 44 and which register with the passages 52 and 54.

A pipe 58 is secured to the valve casing and is connected with a flexible hose 60, which has on its free end a nozzle 62 which will be later and more fully described.

When the parts are in the position shown in Figure 2, water enters through the pipe 40, passes through the valve to the annular passage 5|], flows under the flange 28, and is discharged in a thin, annular sheet around and against the soap 3!).

The soapy water flows over the plate 24 and out through the valve to the nozzle 62, from which this soapy water may be discharged on to the dishes.

The valve is then in what may be called the sudsing position illustrated in Figures 2, 7 and The valve may also be adjusted to rinsing position. For this purpose there is provided in the surface of'the valve 31, 90 degrees around the valve from the passage 44, a longitudinallylower part I4 of the soap container I2, near the side wal thereof, is a pipe 68 which projects to a point close to the top of the member I5. The lower end of the pipe 623 communicates with a passage ID through the bottom of the member I4.

I Passage In in turn communicates with a passage 72 through valve casing 35 and sleeve 36. The valve 31 has in its surface a slot I4 communicating with the passage 44 and adapted in one position of the valve, to communicate with the passages 12 and I0.

It will be seen that if the valve is in the position shown in Figure 2, the sudsing operation can be performed but the passage I4 will be in.- operative. On the other hand, if th valve is turned 180 degrees from the position shown in Figure 2 to the position shown in Figure 5, some water will pass through the passage 48 in the manner hereinbefore described and some water will pass through the passages I4, I2 and III to th pipe 68 and discharge at the upperpart of the soap container. Sudsing can be done while the valve is in this last-named position and some soap will be taken off by the 'water passing through This will wash oflf the upper part of the soap and by closing the faucet valve and discontinuing the water from the faucet, the apparatus can then be permitted to drain.

Soap container supporting means I provide soap container supporting means in the form of a rod 15 extending downwardly from the bottom of the valve casing and terminating in a foot 18 designed to rest on the faucet Ill.

The means for connecting the apparatus with j the faucetfor water flow also contributes to holding the apparatus on the faucet.

At the lower end of the pipe is an elbow 80 from which projects 'a pipe 82 communicating with a faucet connector 84 in the form of a boxlike member, wtih a central upwardly extending tubular member 86, which projects into'the fan-- cet. On the member 84 is a gasket 88. A collar is secured-to the faucet near its discharge end by set screws 92 or the like. Pivoted to the faucet connector 84 are links 93 which are in turn pivoted as at 94 to the arms of a locking yoke 96 having cam-shaped ends 98 adapted to engage the top of the collar 50, looking the faucet connector 84 in place.

By swinging the yoke 96 downwardly, the faucet connector can be disconnected and the entire apparatus can be lifted 01f the faucet.

The discharge pipe 56 is connected by an elbow I06 with a short horizontal pipe I02, Figure 2,

and in turn to a flexible tube 60 already referred to. At the outer end of the flexible tube 60 are the parts forming the discharge nozzle. Tube" 60 connects with a short pipe 6I, which may'functionalso as a handle.

' An internally threaded collar I04 mounted on the pipe BI is formed with an external annular shoulder I06, see Figure 14, and a projecting threaded portion I58. Screwed onto the threaded portion I08 is a larger diameter tube III]. The tube H6 may be molded plastic or any material suitable for the purpose. I preferably use plastic forthe tube H6 and provide on the inside of the tube a plurality of projecting ribs H2 which terminate short of the-threaded end of the tube I I0. Between the ends of the ribs H2 and the collar I64 and tube 6 I, is loosely received a disk I I4 having a plurality of holes H6 to admit the passage of fine streams of water. When the disk H4 is thus loosely mounted, the water from the tube 6| passes through the holes H6 and water can flow around the periphery of the disk I I 4. A considerable flexibility in operation is afforded by reason of the fact that the collar I64 is adjustable on the pipe 6!, For example, by screwingthe collar I64 a little farther on to the pipe 6 I, the tube I II] can be pulled toward the pipe 6| until the disk H4 is snugly gripped between the shoulders H2 and the pipe 6|. In that position of the parts water cannot flow around the periphery of the disk I I4 but must flow only through the perforations H6. I can get regulation of the operation of the nozzle by adjusting the tube I II! on the collar I04 on the pipe'6 I Operation I shall now briefly review the operation of my dish Washer. 7

Assuming that the soap 30 has been placed in position and the dish washer installed on the faucet and the faucet valve has been opened. Then if the handle 35 is in position to hold the Valve as shown in Figure 6, nothing happens. This is the neutral position of the valve.

By turning the valve 90 degrees, water will be permitted to flow from the faucet to the pipe 40 and through the valve and passage 48 to the annular passage 56 formed around the, flange 26, and thence in a thin annular sheet into the soap container and against the soap. Soapy water flows around the edge of the plate 24 to the outlet opening 55, Figure 2.

If the valve is in the position shown in Figure 2, no water flows through the pipe 68 because the passage I4 is closed. If the valve is turned to the position shown in Figure 5, some water will flow through the pipe 68. There is thus afforded an additional flexibility 'of operation. Water flowing throughfthe' passage 55 passes through the'valve'to the nozzle 62 and can be used for washing dishes.- When it is desired to 'rinseithe dishes with clear, hot water, the valve is turned to the position illustrated in Figures 4, 8 and 12. Thereupon the rinse water flows through the passage 66.

In Figures 16 and 17 I have shown a slightly modified form of my device. In this form of the device a plug I20 is placed in the lower end of the passage 48, rendering that passage inoperative. I connect an elbow I22 and horizontal pipe 124 with the upper end of the pipe 68, and put a spray nozzle 126 on the inner end of the pipe 124 for discharging fine streams of water against the soap 30, for the sudsing operation. Otherwise the operation is as heretofore described with the exception that no water passes through the passage 48.

The spray head I26 is shown in Figure 17 in detail and comprises a box-like member, having on its under face a perforated concavo-convex disk I28.

While changes may be made in the details of construction and in the arrangement of parts, I desire to cover such modifications as may be included within the scope of my invention or the scope of the appended claim.

I claim as my invention:

In a dish washer for use with a faucet having a downturned outlet, said dish washer having a soap chamber adapted to be disposed over the faucet, the combination comprising, a rigid tube for supplying water to the chamber, said tube having a horizontal leg for communication with and securement to the outlet of the faucet, a rigid leg spaced from said rigid tube and secured to the chamber and engageable with the upper surface of the faucet, and means for clamping the leg of said tube to the faucet.
