' 4 claims. (01. 141-4) UN IT -J AT- This invention relates to machines for washing dishes and the like wherein the objects to be washed are placed in an openwork rack and are successively subjected to sprays of soapy water which cleanses-the dishes and rotates the rack, and in particular; to improvements in the construction of the rack. i

One objectof this invention is to provide a dish-supporting rack for a dishwashing machine in which the partsof the rack subjected to wear may bev removed and replaced.

Another object is to provide a dish-supporting rack for a dishwashing machine in which novel means for retarding the speed of rotation of. the

rack are provided so that the dishes will be sub- Jected to the most effective and efllcient scrubbing action of the water. i

A further object is to'provide an openwork wire rack having; lower section and. an upper section in which novel means are provided for 4 A still further object to provide novel means for lubricating the rotating rack in a dishwashing machine. 1

A still further object isto provide an openwork wire rack of improved construction which'i'seasy' extending members or posts 24 which are spaced circumierentially around the rings 23 and'which are connected thereto at their crossings. lower ends of the members 24 arebent inwardlyto manufacture and relatively cheap in cost.

These and other objects which will be made,

apparent to thoseskilled in this particularart are accomplished by means of this invention, one embodiment of which is described inthe following specification and illustrated in the accompanying drawings, wherein;.

Figure 1 is a front view in section of a dishwashing machine provided with a rack embodying my invention, portions of the washing chamher and rack being broken away for convenience of illustration; Fig. 2 is a view in elevation of the rack;

Fig. 3 is a partial view in perspective showing the means for supporting the upper section of the rack on the lower section; and

Fig. 4 isa view in sectionof the rack-supportingbearingand associated pin.

-Referring to the drawings in detail, It designates a portlon'of a sink, or other, kitchen fixture, havinga dishwashing chamber or compartment ll formed integral therewith. "Leading from the bottom of the compartment, or chamber H is a drain pipe 12 having a valve is for closing and opening the drain. The valve I3 is operated by a hand lever l4 mounted on theupper portion of the sink I 0. The drain I2 is connected above the valve It to the inlet side of rA Ti Nr OFFICE-f. I

a centrifugal pump Ii that-is driven by an electric motor IS. The outlet side of the pump l5,

is connected to a nozzle H which issecured to the bottom of the washing compartment ll and extends upwardly therein. From this construc- 5 tion it is apparent that when the dishwasher is in operationwater is drawn from the chamber H by the pump l5 and forced into the chamber through the nozzle I]. 'The washing waterleaving the nozzle strikes against the dishes in a rack 10 I8 which is rotatably mounted on a pin l9 extending upwardly from the bottom of the cham ber I l, cleansing the dishes and imparting rotational movement to the rack. My improved dish-holding rack =l8 comprises 1 an openwork basket 20 which is adapted to receive the plates and larger pieces of tableware, an upper tray 2| in which the cups, saucers and the lighter pieces of table ware are placed, and

an-inner container-22 in which'thesilverware g0 and the like is received. r

The basket 20 isoi openwork' construction so as to permit the free access of water therethrough and is formed of a series of concentric rings 23 which are spaced apart vertically to 25 form the side wall of the basket. The rings"- are held in their spaced relationship by vertical The 30 as at, 25 toward the center of the basket to form an openwork bottom therefor. Dishes or other objects placed in the basket areprevented from I passing between the ends 25 of the members 24 35 -by a ring 2 6.which is. concentric to the rings 23. V The ends 260i alternate members 24 terminate in ,a bearing sleeve 21 which isadapted-to be mounted on the pin l9 when the basket is positioned in thechamber II.

-21 may be readily removed and replaced when it becomesworn, the sleeve 21 has anvoutwardly So that the bearing 40 extending flange 28 which receives the endsv 25 of the members 24. The, ends of the members 24 are clamped to the flange 28 and securely 45 held thereon by a washer 29 andnut 30 which is threaded over the sleeve 21. Theends of'the remaining members 24'terminate atand are secured to the ring 26.

In order that the rack It will freely rotate on 50 the pin H, the bearingsleeve 28' has openings .3l formed therein which permit the soapy washing water to flow into the sleeve and lubricate the In order that the Sui-me of the dishes will 'be 56 presented to the scrubbing action of the water, the basket 20 is provided with partitions 32 which hold the dishes on edge in the basket and prevent them from being slapped back and forth against each other. The outer ends of the wire partitions 82 are secured to the rings 22 and in order that the dishes will be held at an angle and act as turbine vanes to rotate the basket, the inner ends of the partitions extend at an angle from the radial center of the basket and are secured to the ring 26. The basket 20 is also provided with vanes 23 which extend downwardly therefrom and are secured to the members 25. The purpose of these vanes will be hereafter explained.

The upper portion of the rack or tray 2| which is adapted to receive the cups, saucers and similar ware, is also of openwork structure, and comprises an upper ring 84 and a lower ring 25 of substantially the same diameter as the rings 23 of the basket 20 and which are connected together by vertically extending members 36 spaced circumferentially around the rings. The lower ends 21 of the members 26 are bent inwardly and extend toward the center of the tray to form an openwork bottom therefor. The inwardly extending ends 21 of alternate members 36 have struck-up portions 38 to provide upwardly extending projections for receiving cups, tumblers and the like, and the extreme inner ends are secured to a ring 20 of such size as to give access to the silverware container 22. Concentric rings 40 are secured to the ends I! of the members 36 and prevent ware from passing therebetween.

In order that the tray 2| may be readily placed and supported on the basket 20 at three points, a series of members 4| are secured to the lower ring ll of the tray which are offset adjacent the bottom of the tray to form seats 42 which are adapted to rest on the upper ring 23 of the basket 20. Y

The silverware container 22 which may be formed of any suitable material and of any desired shape, has a tubular member 43 secured to the bottom thereof which is adapted to fit over the sleeve 28.

when it is desired to operate the dishwasher the basket 20 is placed on the pin is and the plates and heavier pieces of tableware are placed therein between the partitions "22. The tray 2| is then placed on the basket 20 so that the seats 42 on a the members 4| rest on the ring 23 and the cups,

saucers, .tumblers and lighter ware are placed therein. The valve II in the drain is then closed and water is poured into the chamber il until the vanes ll on the basket are covered. The motor I l is then started and the pump Ii draws water from the chamber and forces it through the nozzle I! so that it impinges against the dishes in the basket 20. This action of the water striking the dishes sets up a scrubbing action and also causes the basket to rotate and the speed of rotation of the basket is controlled by the vanes 23. These retarding vanes prevent the basket from exceeding a certain speed and keep it within limits favorable for dishwashing; that is, limits which will subject the dishes to the most efilcient scrubbing action of the water.

It is to be understood that certain modifications may be made herein without departing from the spirit of this invention or the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. A dish-supporting basket comprising a series of vertically spaced concentric rings forming the framework of said basket, vertically ex- 5 tending members connecting said rings together and having their lower ends bent toward the center of said rings to form a bottom for said basket, and a sleeve member tying the inwardly extending ends of said members together and 10 forming a. center bearing-for said basket, said sleeve having an annular flange projecting therefrom and a nut threaded thereon for clamping the ends of said members against said flange.

2.
