DISHWASHING DEVICE.

Application filed February 12, 1921. Serial 110. 444,467.

To all whomit "my concern.

Be it known that I, J osnPH HAUK, a citizen of the United- States, and resident of Shorewood, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Dishwashing Devices, of which the following is a description, reference being had to the accompanying drawings, which area part of this specification. I

The invention relates to motor driven dish-washing machines. In localities where a supply of water under pressure is not available, but where power may be readily furnished for running a dish-washing machine, it is desirable to supply the machine with water under pressure and to store a supply of rinsing and soapy water for use in the machine. It is the object of this invention to meet this condition by providing a dish-washing machine in which the power for operating the machine is used to supply rinsing water and soapy water under pressure for use in the machine from storage tanks upon the machine which may be readilycharged and emptied of their contents.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a vertical sectional view taken through a device embodying the invention; Fig. 2 is a plan view of the machine; Fig. 3 is a section taken on the line 33 of Fig. 1; Fig. 4 is aside view of the machine, parts being broken away and parts being shown in section; Fig. 5 is a detail side view of the machine showing the storage tanks in elevation and parts of the fluid connections being shown in section.

In the drawings the numeral 6 designates a receptacle supported on a spider 7 carried by upright legs 8 which are braced intermediate their ends by cross-frame members 9 upon which the base plate 10 is mounted. An electric motor 11 is mounted on the base 10 and drivingly connected by a belt 12 and pulleys 13 with a shaft 14. The shaft 14 carries a pulley 15 connected by a belt 16 to a pulley 17 on a shaft 18 Journalled in a bracket 19 secured to a sleeve bearing 20 which is mounted on and extends below the spider 7. The shaft 18 is provided with a worm 21 meshing with a worm wheel 22 upon an upright shaft 23 journalled in the bearing sleeve 20. The upper end of the shaft 23 supports an armed bracket 24 car'- rying a dish-carrying basket 25 which is mounted within the receptacle 6 and re- 0 volved through the belt and gearing connections just described on a rotation of the motor 11. 'hile a motor is preferred it will be understood that any suitable source of power may be used to drive the shaft 14. 5

A pair of storage tanks 26 and 27 for holding soapy water and rinsing water, respectively, are connected to a hooked bracket 28 engageable with the upper edge of cylindrical shell 29 which encloses the opearting mechanism disposed between the spider 7 and the base 10. This hook connection permits the tanks to be shifted or bodily moved by hand from one side to the other of a discharge spout or drain 30 from the receptacle 6 whereby the water or washing fluid in the receptacle 6 is conducted from said receptacle back into that tank whose open end is positioned below the spout. Pipes 31 and 32 connect the tanks 26 and 27 with a valve fitting 33 in which is disposed a three-way valve 34 having a passage 35 to connect either one of the tanks 26 and 27 with a drain 36 and a flexible pipe or hose 37.

The pipe 37 leads to the inlet 38 of a centrifugal pump 39 the rotor of which is mounted on the shaft 14 and driven thereby to force the water or washing fluid through a pipe 40 which connects with pipes 41 and 42. I 7 9c The pipe 42 is preferably flexible and 0on meets with a conduit 43 carried by a cover 44 which is hingedly connected at 45 with the receptacle 6. A rotatable spray nozzle .46 is secured to the end of'the pipe 43 and directs. the spray of cleansing fluid down upon the dishes in the basket 25. The 1nlet pipe 47 i journalled in a nipple 48 and carries a flange portion 49 running on ball bearings 50 seated in a recess in the upper no end of the nipple 48. and a second series of ball bearings 51 are interposed between the lower end of the nipple 48 and a collar 52 on the pipe 47. The nozzle member 46 similar to well known sprinkler heads rotated by the reaction of a jet of water has an inclined spray pening 53 at one end and a weighted portion 54 at the other end and the water under pressure from the pump 39 passing through the pipes 40, 42 and 43 and into the nozzle. serves to rotate the same while the spray is directed through the opening 53 down onto the dishes in the basket 25.

A nozzle 46', similar to the nozzle 46, is similarly mounted upon the upper end of the pipe 41 and is disposed below the basket 25 so that the water from the pump passing through the pipe 41 is delivered by the nozzle, during its rotation, against the bottom portions of the dishes in the basket 25. With this construction, when the motor is started in operation and the dishes are placed in the basket 25 the nozzles 46 and 46 direct their streams toward the top and bottom portions of the basket and against the dishes therein to efliciently clean them,the nozzles being eccentrically located with respect to the axis of rotation of the basket so that the spray may reach all the dishes in the basket. and as the water passes to the bottom of the receptacle it returns by way of the drain 30 to either of the storage tanks 26 or 27 from which it is being drawn by the pump. When hot soapy water is desired the tanks are disposed inthe position shown in Fig. 5, and after this water has been applied the valve 34 may be turned to shut, off communication between the pipe 31 and the pipe 37 so that the soapy water in the system may be returned to the tank 26, and then the tanks may be shifted so that the tank 27 comes under the spout 30 and the valve 34 turned to bring the pipe 32 into connection with the pipe 37, thereby shut-- ting ofl' connection between the pump and the tank 26 and establishing communication between the tank 27 and the pump so that rinsing water may be supplied to the washing nozzles of the machine, and after-the rinsing is completed the valve 34 may be turned to shut off communication between both tanks 26 and 27 and the pipe 37 to return the rinsing water to the tank 27 from there'ceptacle 6. After the washing is completed the tanks 26 and 27 may be emptied, one at a time, by turning the valve 34 to the proper position and by turning the drain cock 36 to'open position.

I desire it tobe understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are specified in the claims. 7

What I claim as my invention is:

1. In a dish-washing machine, the combination of a receptacle, a dish-carrying basket mounted therein, a nozzle directing washing fluid upon the dishes in said basket, a discharge spout at the bottom of the receptacle, a support, a pair of fluid supply tanks mounted on said support and movable so that one or the other may be dis posed below said spout, a motor-driven pump mounted on the machine, piping con necting said pump with said tanks, a valve in said piping controlling the flow of fluid from either one of said tanks to'said pump, and pi ing from said pump to said nozzle to con not the fluid under pressure to the ame.

2. In a dish-washing machine, the combination of a receptacle, a dish-carrying basket mounted therein, a nozzle directing washing fluid upon the dishes in said basket, a drain for said receptacle, a pair of fluid supply tanks movable with respect to the drain for selective use, a motor-driven pump, piping connecting said pump with said tanks, a valve in said piping controlling the flow of fluid from either one of said tanks t said pump, and piping from said pump to said nozzle to conduct the fluid under pressure to the same. v
