DISHWASHING MACHINE.

Application filed February 20, 1924. Serial No. 694,037.

To all whom it may concern:

Be it known that I, VVILBERT L. SOUTH a subject of the King of Great Britain, an a resident of Ontario, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Dishwashing Machines, of which the following is a specification.

My invention relates to dish washing machines, and a purpose of my invention is the provision of a dish washing machine particularly designed for domestic purposes and embodying a casing in which a plurality of dish supporting trays are sustained for rotary movement, and means by which jets of water are caused to impinge upon the dishes for not only washing the latter but for rotating the trays to successively present the dishes to the jets to effect the thorough washing of all of the dishes. 7

It is also a purpose of my invention to provide a dish washing machine in which ,the dish supporting trays are sustained for rotary movement u on a common shaft which is supported or lateral movement to swing the trays into or out of the casing,

thereby facilitating the application and re moval of the dishes to and from the trays A further purpose of my invention is the provision of a dish washin machine in which a non-friction supporting bearing is provided for the tray supporting shaft and which includes a member of relatively hard material, such as glass or the like, yieldingly supported to prevent breakage of the member should the shaft be subjected to an excessive load.

I will describe only one form of dish washing machine embodying my invention,

and will then point out the'novel features thereof in claims.

In the accompanying. drawings Figure 1 is a view showing in side elevation, and partly in section, one form of dish washing machine embodying my invention;

Figure 2 is a transverse sectional view taken on the line 22 of Figure 1;-

Figure 3 is an enlarged fragmentary sectional view of the bearing for the shaft em.- bodied in the machine shown in the preceding views,

Referring specifically to the drawings, in

which similar reference characters refer to similar parts, my invention in its present embod ment comprises a casing C of rounded form and having a flat side provided with an opening controlled by a door D hinged at the point 15 and adapted to be secured in closed position by means of a latch L. This door is ,provided with a glass panel 16 through which the operation of the machine can be observed at all times.

\Vithin the casing G are secured spaced bearings 17 and 18 to receive a vertically disposed shaft 19, and secured to the shaft are sleeves 20 and 21 provided with arms 22 and 23,-respectively, disposed at right angles to the shaft 19 and having vertically alined cups 24; and 25 in which the opposite ends of a shaft 26 are received. As clearly shown in Figure 3, the cup 25 receives a bearing disk 27 formed of glass or other suitable material, and this disk is yieldingly supported upon a disk 28 of cork or similar material,

the disks 27 and 28 for the purpose of pre venting water from coining into contact with the cork disk and thus destroying its resiliency. The cup 25 is interiorly thread ed to receive a flanged bushing 30 into which extends the lower end of the shaft 26. The shaft 26 is provided with a conical end 31, the point of which bears directly upon the glass disk 27' and thus provides a non-friction bearing for the shaft. The cork disk 28, in prbviding a yielding support for the bearing disk 27, allows the latter to move downwardly when the shaft 26 is subjected to an excessive load, thereby preventing breaking of the glass disk, as will be understood.

Detachably secured to the shaft 26 are a series of dish supporting trays. one of Whichis designed to support dishes in an upright position to allow a jet of water to impingepgainst the dishes in a manner to set up rotary movement of the, tray so as to propel the shaft 26 and thus cause rotary 26 provided with three dish. supporting 195 traysdesignated T, T and T The lowermost tray T is shown in Figures 1 and 2 as comprising two sections 2% and tmade of wire and constructed so as to cooperate to provide an outer ring 32, two intermediate rings 33. and an inner ring 34. The two sections are secured to the shaft 26 for rotation with the latter by means of a pair 'of brace rods 35, which, as clearly shown the shaft by bolts 36 having wing nuts 37. Curved extremities 38 receive the ring 34 to support the latter in fixed position upon the shaft. The rings 33 are adapted to be soldered or otherwise secured to radial rods 39 secured at their ends to the rings 32 and 34 and circumferentiallv spaced with respect to each other. Vertically disposed semi-circular rods' 40 are secured at their ends to the rings 32 and 34, one rod 40 for each of the rods 39, and arranged above and at one side of the rod 39 for the purpose of accommodating a dish.

From the foregoing construction it will be seen that the'tray T provides a plurality of dishsupporting brackets arranged radially on the tray, the rings 33 of each bracket supporting the edge of a dish and the rods 39 and '40 co-acting to support the dish in vertical position. Thus the several brackets are adapted to support a plurality of dishes radially upon the tray and in upright position. J

I Thetray T is constructed in a manner similar to the tray T but is provided with L-shaped rods 41 which coact to support platters, designated at 42, in upright posi tio'n upon the tray. The tray T is constructed to provide a circular series of radially disposed rods 43 between which tumblers are supported. .Brackets 44 are in- T--. The pipe 45 extends exteriorly of thecasing, where it may be connected to a source of water su ply. The nozzles N and N are each provid d with ports 46 and 47 (Figure 2), from which jets of water emanate, as indicated by the arrows 46 and 47 The angle of the jet 46 is such as to impinge upon one face of the plates and to thereby exert its force in effecting rotationof the tray as a. whole, thereby not only washing one side of the several plates but succes= sively presenting the plates to the jet. The" jet 47 impinges against theback or other face of the plates and thus washes the reverse side. Thisjet also tends to oppose.

. the propelling action of the jet 46 and thus prevents too rapid rotation of the tray. Under the rotative movement of the trays '1 and T the shaft 26 is likewise rotated, thus setting up rotative movement of the tray T so as to successively present the cups and tumblers to the spray emanating I from the nozzle T By virtue of the mounting for the shaft 26, the several trays 'can be swung from the position shown in solid lines in Figure 2 to the position shown in dot and dash lines, the arms 22 and 23 swinging outwardly through the opening of the casing, thereby shifting the several trays to a point exteriorly of the casing, where ready access is had to the trays to permit cleaning of the same and to apply or remove the dishes to or from the trays.

Although I have herein shown and described only one form of dish washing ma- I chine embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

What is claimed is:

1. A dish washing machine comprising a dish supporting tray mounted for rotational movement, and a nozzle for directing one jet of water against one side of the 'dishes carried by the tray in a manner to effect rotation of the tray, and anotherjet against the opposite sides of the dishes to oppose the propelling-action of the first jet and to wash the dishes.

2. A dish washing machine comprising a casing having 'an' opening in one of its vertical walls, a shaft supported for rotational movement in the casing, dish supporting trays supported on the shaft, means in the casing for directing jets of water against the dishes on the trays for causing rotation of the trays and washing of the dishes, asecond shaft rotatably' mounted in the easing, arms fixed to the second shaft and rotatably receiving the first shaft whereby the first shaft and trays can be swung into and out of the casing through said opening.

3. In a dish washing machine, a casing having an opening in one of its vertical walls, a shaft supported for rotation in the casing, dish supporting trays fixed to and supported on the shaft, and means for supporting the shaft to permit lateral movementof the shaft and trays into and out of the casing through said 0 ening.
