eferring to the draw1ngs:-

1 designates my novel construction of dlsh washer, the same comprising a tank or casin'g 2, having the bottom wall 3, whose inner periphery 4 is secured to or supported on the ledge 5 of the casting it member v6, which is `provided with the grain pipe 7 having the valve or cock therein. The central bottom portion of the sump or wheel pit member '6 is provided with the vertical bearings 9, in which is mounted the pro eller' shaft 10, which passes through the stu g box 11, the lower end 'of said shaft having the coupling 12, which is attached to the coupling 13 of the motor shaft 14, which is driven `by the electric motor 15 of any desired or conventional type. The motor is l supported by means of the brackets 16,

whose upper ends are bolted or otherwise secured to theouter portion of the sump or wheel pit member' 6.

The upper end of the driving shaft 10 is provided with a'suitable thrust bearin 16", and terminates `in the propeller sha t 17, which carries the upper and lower propellers 18 and 19, which rotate and are contained in the vertical conduit or stand pipe 20, whose lower end is supported upon the seats or shoulders 21"'of the upward extensions 22 which are preferably cast integrally with the 'sump or wheel pit member 6.

Below vthe propellers, I locate the umbrella l shaped deflector 37, thereby forminothe bottom sediment chamber 38, which receives the heavier particles or impurities.

About the middle of the conduit 20, I locate the ports 23, which are adapted to direct the water or other cleansing agent upon the lower articles, as plates, or the like 24, which are supported on the lower rackscreen or basket 25, and in the upper portion of said conduit, I locate the ports 25", which are adapted to direct the water upon the smaller articles as cups 26 or tumblers 27, which are supported upon the upper rack, screen or basket 28.

In the upper portion of the conduit 20, 1 locate the bar or spider 29, on or in which. is supported the lower end of post 39 on the upper end of which is looscly'mounted the rotary water sprayer or spreader 30, which is retained in position by the wing nut or the like 31, the lower-surface of the rotary spra erbeingslightly above the top of the con uit20,-andshayipgwits bottom composed sump or wheel of a pluralityof pockets as three or more of novel construction, whose function is to forcibly .discharge the water downwardly in different planes upon the articles to be washed, it being understood that said sprayer is continuously rotated by the force of the water impi'nging on its under side, which is discharged or propelled upwardly through said conduit or stand pipe.

The racks', screens, or baskets 25 and 28 are supported within the casing 2 by any convenient means as the lu s 32 and 33 and upon the upper surface of the lower rack, screen or basket 25, I preferably provide a series of curved or tangential ribs as 34 against or upon which the lower edges of the plate or the like 24 may be supported, said ribs having the function of splashing or deflecting the streams of water impinglng thereon, it being evident that the upper rack or basket 28 may also be supplied with such ribs.

The lower end of the vertical stand pipe 20 may be supported on the osts 22 in any suitab e manner, but I prefgrably provide the same with an'gular slots 35, which are adapted to engage the pins 36, so that on dropping the stand pipe in position and giving it a slight rotation, the slots in the lower portion thereof will interlock with said pins 36.

I desire to call special attention to the construction of the plurality of pockets on the underside of the rotary water sprayer or spreader 30, reference being had to Figures 7 to 11, which will now be described in detail.

The rotary water sprayer or spreader 30 revolves freely on theoupper end of the post 39, which passes throu h the hub member 40 of said sprayer. The ottom surface of the sprayer is normally slightl above the to of the stand pipe 20, as will be understoo from Figure 1, and its bottom is constructed with the plurality of pockets 41, 42 and 43 of successively decreasing depth and whose top walls as 44, 45 and 46 are each of slightly different contour, as will be understood from Figures 9, 10 and 11. The deepest pocket 41, see Figure 9,has the abutment or wall 47, and its upper edge 48 is cut away or is a slight distance from the bottom of the sprayer, Aso that the water can emerge from the pocket l4l in a lateral direction in a whirling manner. The pocket 42 has the abutment or wall 49, as will be understood from-Figures 10 and 8, and its top ortion is of slightly different contour from t e top of the pocket 41, as is evident.

The pocket 43 has the abutment or wall 50 and its top wall 46 is slightly concave, as will be understood from Figure 11.

Itwill be seen from the foregoing that the three pockets 41, 42, and 43 are all of slightl different contour, so that the water which7 is discharged against them upwardly through the stand pipe 2O emerges laterally,

arrasar is given not only a spiral or whirling action but is continuously discharged iny i'erent planes, it being ap arent that the spreader rotates automatica ly due -to the upward pressure of the water column in thestand pipe 20.

he operation is as follows The cover 51 having been removed, it will be apparent that the plates or similar shallow articles can be supported upon the lower' basket 25 in an inclined direction, as will be understood from Figure l, the screen 28 being'removed so as to enable the plates or the like 2t to-be laced in position. The screen 28 is then p aced in position and the smallerarticles to be washed, such as cups and tumblers 26 and 27 having been placed upon the sereen28 and the motor 15 being started, it will be a parent that the action of the ropeller or ouble propellers 18 and 19 wi be to force a constant current of water u wardly throuigh the standy pipe against the under side o the rotary spreader 30.

The rotary spreader 30 is automatically rotated and not only discharges the water in a whirling or spiral direction laterally and downwardly upon the articles to be washed, but in addition, such articles are subjected to the action of the streams which issue through the ports 23 and 25x whereby all the articles are edectively washed.

llt will be apparent that the inlet end of the stand pipe 20 is somewhat below the water' level of the water contained in the wheel pit or well formed above the bottom 3 and the wheel pit 6, so that a fresh supply of comparatively clean water is continuously discharged upon the articles to be cleaned, the scum, grease and the like remaining on the water level.

By the provision of the laterally shaped de- Hector 37, the heavier articles which settle by gravity are directe into the bottom of the wheel pit and can be readily withdrawn.

through the valve pipe, 7, according torequirements.

llt will be seen from the foregoing that only a small amount of power is required for forcing the water through the stand pipe 20, by means of the propeller wheel or wheels, which are directly connected by their shaft to the motor drive, which is suitably packed to prevent leaka e. By the provision of the vertical stan pipe having slots -cut in it on levels suited to the racks, screens or baskets which carry the dishes which are on an angle, a continuous stream of water is forcibly directed in allfdirections directly upon t e surface of the dishes placed on the racks.

The revoluble sprayer or spreader at the top ofthe stand pipe havin the plurality of pockets on its bottom sur ace arrests the water in its course upwardly and overowing at .the top and impinging a ainstsaid pockets causes said sprayer rapid y to rotate and as there are varyin degrees of openings in the periphery of said s rayer, the direction of the water is change or altered from ri ht angles in the stand pipe down to the ang e of 35, so that l t a wide distribution of the water u an down the sides of the tank thus creating an edective scouring action, due to the di'erent angles of the water, as well as the rotating edect given to the water by means of said sprayer. This action is most ecient in instantly cleansing the surface of the dishes to be cleaned.

Attention is also called to the fact, that the machine is rapidly taken apart for the purpose of cleaning, ins ection or repair, and it is readily accessib e at all times for this purpose.

Another highly important feature in this machine is the fact that once the grease and foreign matter adhering to the dishes are removed, the grease being lighter than water, floatson the surface of the same and as the bottom end of the stand pipe extends below this surface, the action of the water propelled device is to force `upwardly the clean water beneath the surface or water `level and throw it over the dishes, so that l do not throw the accumulation of what has been taken from the surface of the dishes and deposit it back again 4on them during the operation of cleaning.

By the provision of the wheel pit member 6 in the bottom of the tank, a well is formed so that l get a solid and constant volume of water supply at all times, and the umbrella shaped dedector 37 having the space 38 beneath it forms a sediment pocket, where the heavier particles of foreign matter will settle, which are readily drawn od by means of the discharge pi e 7, thus further insuring cleaner'water or the dish washing operation. l

It will now be apparent that l have devised a novel and useful construction of a dish washer, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while l have in the present instance, shown and described preferred embodimentsthereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages. lt will now be apparent that l have devised a novel, and useful construction of a dish washer which embodies the features of advantage enumerated as desirable in the ltd statement of the invention and the above 4 rae facmlyandl--reiiable Resultaat is .to be understo .that such embodiments arey s usceptiblefofnOdfication in l various partlculars 'f'withoutfdeparting from the spiritor sco e of the invention `or sacrificing any of its advantages.
