Serial No. 128,277.

My invention relates to mechanisms or machines forwashing and rinsing dishes which are adapted to be assembled and operated in the usual kitchen sink, and the special object of my invention hereinafter described is to provide a removable cover so constructed that when placed in position it will allow the faucet levers and soap supply means to extend above and outside of said cover for convenient manipulation while insuring effective prevention of the water-being sprayed on the dishes from escaping in any dii ection outside the limits of the cover or sink.

' ll attain these objects by means of the mechanism which will now he described in detail with reference to the accompanying drawings, which show a complete sink dish- Washing machine.

Figure 1 is a front View, sectional through."

the sink and. cover, and Figure 2a cross section view substantially on line 2, 2' of Figure 1, showing the preferred construction, with the soapholder permanently combined with the water outlet fixtures.

Figure 3 is an enlarged View, partly in section, showing the details of construction of the soap container and its by-pass valve, as shown in Figures 1 and 2. Figure 4 is a cross-section view at line 6 of Figure 3, with thesoap container valve turned to shut ofl the flow of water through it.

Similar reference numerals refer to similar parts throughout the several views.

The sink 10, which may be of any size 6r type in pse, has the usual outlet 11 carrying the water oil' to the drain pipes. The sink is provided with the usual hot and cold water supply pipes 8 and 8'. These water supply pipes are connected up to a single outlet spout 19 by means of the communicating passage 19, as shown in Figures 1, 2 and 3. The usual control levers 9 and 9' serve for turning the water on or oil at will.

The rotary' spray outlet of this machine comprises essentially the hollow globular head to which are secured radial outlet tubes 13 and a central vertical tube 14. The globular head 15, or itsequivalent, is'permanently connected with the nut 16 by means of a suitable bearing, substantially as is shown by the dotted lines in Figure 3, so that it will rotate freely on its vertical axis. The nut 16 serves to attach this rotary spray outlet to-the water spout outlet 19. The radial and vertical tubes 13 and 14 are provided with a number of small openings or nozzles 17 which .areof stich size and number and so located as to cause the water jets to issue therefrom with suflicient velocit the streams so well distributed 1n direction as to give the most efi'ective results in cleaning the dishes. The openings 17 are so located on the radial arms 13 that the rev action pressure of the jets therefrom will cause the continuous and rapid rotationof the device as long as waterunder plied to it. v

The dishes to be washed are arranged in a suitable rack 18, preferably constructed of wire and circular or rectangular ll'li shape in order that {the dishes may be suitably arranged to expose them to the cleaning action of the sprayed water jets so as to secure the most rapid and eflicient washing. A suitable enclosing cover 32, preferably made of sheet metal, is essential to confine the sprayed water within the sink when the machine is in operation. A detailed description of this cover will be given later.

The construction of the soap supply valve and holder is shown clearly in Figures 3 and 4. It consists essentially of a cylindrical cup 20 secured to the top of the by-pass valve 21. This valve.is tapering and is provided pressure is supwith the direct port 22 and the recessed ports 23 and 23, the two latter communicating with the interior of the soap holder 20. A screen wire or perforated partition 24 is located near itsbottom, and an open inlet tube 25 is provided with its lower end connecting with the inlet port 23, and extending nearly to the top of the soap holder. The screw top 26 allows ready access to the soap holder when desired to put soap therein. When the container 20 has been supplied with soap and the parts are in the position shown in Figure 3 with the hot water supply faucet lever and with I open-, hot water will flow. into and through the recessed ports 23 and 23 and the soap holder 20, dissolving soap therein and the resulting hot-water suds will flow through the outlet spout 19 into the rotary spray outlet, and out through the openings 17 and 17' as high velocity jets. The short arrows indicate clearly this circulation of the water clear hot water will pass directly through the port 22. Two openings 27 and27" are provided in the wall of the valve seat so that when the valve has been turned to the position shown in Figure 4 the hot water remainin in the soap holder 20 will automatical y be drained oil into the sink through the tube connecting with opening 27 air being admitted through the opening 27 to replace the water. This is quite essential as otherwise the soap remaining in the container would be more or less completely dissolved, resulting in a very rapid and wasteful use of soap. The word Soap on the container 20 is so located that it will face to the front as shown in Figure 1 when the valve is in position to send the entire flow of the water through said soap holder as shown in Figure 3, thus visibly indicating when soapy water is being used.

The. removable cover to enclose the dish rack and confine the sprayed water within the sink when the machine is in operation comprises essentially a top member 32 with side walls 32 which extend down a suflicient distance below the top of the sink to prevent the escape of the sprayed water. An opening 33 in the rear side wall 32, and a similar opening in the top member 32 of the removable cover allows it to be readily put in place and removed notwithstanding the soap valve 20 and faucet levers 9 and 9 which should extend through the opening in the top member 32 convenient for manipulation by the operator. The cover may be of substantially the same oval or rectangular shape as the wire dish rack.

It is very essential that the opening in the top 32 through which the control levers and soap valve extend should be closed so as to prevent the escape of water through it while the machine is in operation. The section 35 which is provided for this purpose is permanently secured to the splash-up back of so that the main removable cover 32 will be accurately guided into position held suspended from said fixed shelf or lid 35. The clips 36, secured to the front side of the cover may be used also as an additional support by resting on the front edge of the sin It will be evident that the machine may be provided with a plurality of dish racks at small additional cost, thereby increasing its capacity per unit of time to any desired extent.

What I claim as my invention is: t

1. .The combination with a sink provided with a back wall, a water-supply conduit and a valve in the conduit, of a spray device secured to the conduit, a dish holding rack extending below said device, and a cover to confine the sprayed water within the sink, comprising a horizontal section permanently secured to the back wall of the sink below the valve and throu h which the conduit extends, and a removaldle section provided with a recess to fit closely the horizontal section.

2. The combination with a sink provided with a backwall, a water-supply conduit, and a valve in the conduit, of a spray device socured to the conduit, a dish-holding rack extending below said device, and a cover to confine the sprayed water within the sink, comprisinga horizontal section permanently secured to the back wall of the sink below the valve and through which the conduit extends, the said section being provided with a shoulder at its free edge, and a removable section provided with a recess to fit closely the shouldered portion of the horizontal section.

FRANK MCCLINTOCK.

the sink by means of'the vertical flange which is (provided with openings for the pipes 8 an 8' and securely held in the position shown by the usual flanges and fittings thus forming a secure andpermanent shelf below the faucets and soap valve. Its edges are recessed at the front and side-as clearly shown in Figures 1, 2 and 3, thus forming a ledge 34 corresponding in sha e and size with the opemng inthe top mere 1' 32 of the cover.
