21 for a soapy solution, such as liquid soap, which reservoir maybe formed, in part, of two corner portions of the tank 17 and a diagonally extending wall 23, soldered or otherwise secured to said corner portions of the tank walls. The bottom 24 of the tank 17 forms the bottom of the reservoir 21 and the diagonal wall 23 may be extended across the upper end of thereservoir, as at 25, to form the top wall thereof. A filler opening is provided in the top wall 25 of the reservoir which is closed by a filler cap 26 threadedly or otherwise secured upon an lupstanding nipple in which the ller opening is Removably supported in the tank 17 is a basketor tray 27 for holding the dishes to be washed. Said basket or tray may be formed of lengths of wire bent up and se- -cured together -to provide the open-work bottom and sides of the basket, and, if desired, the basket may' contain spaced upright wire members 28 between which iiat dishes, such as saucers or plates, may be stood edgewise during the washing operation. Brackets 29 secured to the inner faces of the walls of the tank 17 are provided for removably supporting the basket or tiay 27 in the tank.
Below the tank 17 is a compartment 30 in which is contained the apparatus for pumping the water used; for washing the dishes, and said pumping* apparatus will now be described. Supported within the compartment 30, as, for instance, upon an angle iron frame 31 secured" to the walls of the case 10, is Aa platform or other support 32, here shown as extending diagonally across the compartment 30, and upon 'said platform are mounted an electric motor 33 and two water pumps 34 and 35, the shafts of which are connected to the motor shaft 36 and driven by the motor. The pumps are lo- 'cated one on each side of the motor, andl are held in fixed position with respect to each other by the base or platform 32. This arran ement also provides simple means where y the electric motor may be centered with respect to the axes of the pumps and permanently held in such centered position with relation thereto.
The pump l34 supplies water, under relatively high pressure, for washing and rinsing the dishes, and the pump 35 operates to dischar e water accumulating in thel tank. Prefera a ositive gear pump in order to obtain sucient pressure to discharge the water against the dishes at relatively high pressure. The pump 35 may be in the nature of a centrifugal pump, since its function is merely to discharge the water from the tank into a kitchen sink or other receptacle.
To the'intake end 39 ofthe pump 34 is secured a length of hose or iiexlble tube 40 -ing the reservoir 21 with the ly, the pump 34 is in the nature of which extends to one wall 11 of the case where it terminates in a coupling member 42 from which leads a removable extension 41 attached to the hose 40 by a companion coupling member, and said extension 41 terminatesin a nipple or cup-like end 43 which is arranged to be slipped over the nozzle of an ordinary kitchen faucet 44 (see Fig. 1). From the discharge end of the pump 34 leads a length of hose of exible tube 45 which leads upward towards the bottom 24 of thetank 17 and is provided upon its end with a clamp 46 and detachably secured upon a hose connection 47 thatv projects down from the center of thebottom wall 24' of the The hose 45 communicates with a water sprayin or sprinkler device 48 located in the tan (see Figs. 2 and 5) and from which the water is discharged upon the dishes, as will be hereinafter more fully set forth.
Leading from the bottom of the soap reservoir 21 is a pipe 49 controlled by a needle valve 50 (see Fig. 6) removably secured to one of the side walls of the case, and having a hand wheel 51 located upon the outer side of the case. The pipe 4 9 leads to a T-cou- `pling 52 which is interposed between the inlet end 39 of the pump 34 and the hose 40. Itis to be understood that ordinary small pipes and fittings are employed for connect- T-coupling 52 at the pump 34, and, as a preference, a union coupling 53 is provided in the pipe 49, at one side of the Vneedle valve 50 (see Fig. 6), whereby the pumping apparatus may be detached and removed for any purpose, and whereby the tank 17 may also be removed, if desired. vWhen the tank is to be removed, the needle valve is detached the tank. Normally the needle valve 50 is lclosed, but during the initial washing operation, it is opened to permit a quantity of liquid soap, contained in the reservoir 21, to be drawn into the pump 34 along with the water entering through the hose 40, so as to permit the soap to mix with the clear water, whereby the mixture -is thrown upon the dishes. i
'The bottom 24 of the tank 17 slopes towards a drain point which may be located at one side of the tank, and at this lowermost drain point is an opening'55 (se'e Fig. 2) through which the water discharges from the tank.A A hose connector, similar to the hose connector 47, projects down' from the drain opening and a hose or flexible tube 57 is removably'secured to said hose connector and leads to the intake side of the pump 35. A screen is usually provided in the drain opening 55 to prevent solid matter from passing to the pump 35. From the discharge side of the pump 35 leads a length of hose or other flexible tube 58 which extends to a side wall of the case, from which leads from the wall of' i an extension 59, coupled to the hose or tube 58 by a coupling 60 and having upon its termlnal end a goose neck fitting 61 (see Fig. 1) which may be placed over the edge of an ordinary kitchen sink 62 to permit the water coming from the tank 17 to be discharged into the kitchen sink by the pump 35.
A door 63 (see Fig. 1) is provided at one side of the compartment whereby access may be had to `said compartment for the purposeof inspecting the pumping apparatus.Y Said door may 64, whereby the door may be locked to prevent any one from tampering with the pumping apparatus.
The hose connector 47 may be secured to or formed as a part of a pipe connector 65, soldered or otherwise secured to the. bottom 24 of the tank, and threadedly secured in said pipe connector is a nipple 56 upon which is rotatably mounted the spraying or sprinkling device 48, above referred4 to. Said spraying device may be in the form of a plurality of pipes 66 threadedly secured in a hollow head 67 and provided with lock nuts 68 which, when turned up ltightly against the head 67, prevent unscrewing of spraying device rotates.
the pipes 66. The ends of the pipes are closed by caps 69 and a number of nozzles 70 are provided along the lengths of the pipes 66, through which nozzles the water is dis charged in the form of jets or sprays. It
will be understood that by turning the pipes 66 in the head 67,"the nozzles 70. may bemade to lassume any desired angle of inclinationwith respect to the vertical, and that by directing the nozzles of one pipe 66 in one direction and the nozzles of the other pipein the opposite. direction, the spraying device is caused to rotate when water is forced through said pipes and nozzles at relatively high pressure, and the water will be discharged against thedishes contained in the tray above thespraying device from all angles around the axis about which the The connection between the .rotating sprayingdevice and the nipple may comprise a sleeve 71rotatably mounted upon a reduced neck portion 65'of the nipple 65 and threadedly secured -in the head 67. A washer 72 interposed between the upper end of the sleeve 71 and the upper out turned end of the neckl 65.a of the nipple 65. pre- `vents separation between the fitting and sleeve, whereby the sprinkler or spra ing device may rotate on the nipple 65 Wit out -danger of becoming disconnected therefrom.
An extension' cord 75 leads from the electric motor 33 and is` provided with a switch 73 which may be attached to one of thewalls 11 of the case. The extension cord hasan attachment plug 74 upon its end which may be plu ged into any suitable electric socket.
In t e operation of the dish washer, the
e-provided with a lock dishes to be washed are arranged in the bas.
cet and the hose extension 59being placedl upon Ithe-kitchen sink, as shown, the water is turned on and the switch is closed, thereby starting the electric motor and setting the pumps 34 and 35 in operation.
During the initial washing operation, the needle valve 50 is opened to permit a quantity of the liquid soap, contained in the res'- ervoir 21, to enter the pump`34 and mix with the hot water coming from the faucet, but the valve 50 is closed` soon thereafter, thereby permitting clear water to be thrown upon the dishes. The pump 34 forces the water at a relatively high pressure through the nozzles of the spraying device, which device is thereby caused to rotate ata rela- 59 and hose extension 59 into the kitchen sink. When the rinsing operation is ,com-
pleted, the kitchen faucet is closed, andthe switch opened to stop the pumpin apparatus. When all the Water has been' discharged from the tank 17 the hose connections with the sink and kitchen faucet are i detached therefrom, and the dishes removed or left to dry therein.
To remove the tank 17 the union coupling 53 is disconnected, the valve 50 detached from the wall 11 of the case and the two lengths of hose 45 and 57 disconnected from the tank after which the latter may be lifted out of the case. To remove the-pumping apparatus, the lengths of hose 40 and 58 are detached from the wall 11 of the case, the v.union coupling 53 disconnected and the lengths of hose 45 and 57 disconnected from the tank. I
