' My present invention relates-'todi'shwashing or like machines and particularly to the -del ivery systems for the wash water ofsuchmachines.
As, in dishwashing, machines, thewash water: is re-circulatedjit'is necessary to cl eanse'the 'wash water delivery system at 'regu1ar"intervals., In spite of careful screening, such systems generally and the 'manifolds andspray devices in particular, become fouled with food particles and foreign matter. a result both to ensure'the 1 2 Claims. (01. see-141i 1o efllcient operation of the machines and for sanitary purposes, theicleansing 01f thewas h water delivery system is an essential service. Because of the construction of machines prior to-my invention, such service was difficult as it required exterior disassembly of the machines.
In accordance with my invention, I DI'OVidG a washing machine having "awashing chamber in which there is mounte'da dish support ii spaced relation to the sides or the chamber. A wash Water tank receives draina'ge from the washing chamber and pump controlled means incommunication with the tank, deliver wash water to the t b v. V i
' P mp qen lled me n a ri er element supporting "a manifold element in the washingchaniber below thedish supportand the elements/are assembleidftogether'by a quick'releasable connection; Connected to the manifold element, as by bayonet. .joints are a plurality of spray devices'di'sposed between the dish support and an adjacent side of the chamber; and these devices have a plurality of orifices disposed" to deliver sprayagainst' dishes on the support.
The nature of the connection between'the riser and'm'anifold elements depends to a considerable extent; on ,the' type of? dishwashing}.machine. ,Wherejthedish support is a removable basket, the connection may be a joint; of the bayonet type. Where the dish support isan endless iconveyor, the connection is a slidingjoint permitting the top of the manifoldsto be movediendwise fromthe machine tqavoidthe necessity of disconnecting the conveyor. v i
. In accordance with, my invention, :the wash waterdelivery system.v of .dishwashing. machines may be .easily and .effectively:iservicdtas the manifold elements and. the spray-device's "may be readily removed from the machines *as a' :unit
and quickly disassembled for-"thorough cleansing.
In the accompanying drawings, I have shown illustrative. embodiments of my invention from which its novel features and advantages wi l be readily apparent.

The machine in has a cover- I3, hinged as at M to permit the basket l5 for dishes, glasses'and silverware to'beplaced in or removed washing chamber l2; f r v 'The basket 1s supported in spaced relation to the side walls It andl'l or the chamber-I0 by removable guide rails I8 seated on brackets! and mounted on theside walls l6 and, respectively; At'2 l',-I'have indicated a ledge removably supr miih "porting a scrap tray or tfays*22 which 's'erve'to screens substantial part'bfthe food particles and foreign matterfromihewater dr'ainih' be connected to any suitable drain (not shown) 'and at 24 I"have shown afscreen ior'the intake 25" of the pump26 which'may'be'pl'aced where 'sli'own or'located atone end otthetank ll. outlet adjacent one of its ends;

'The;spray:-devices-,
35 have orifices 31 disposed to direct jets of spray" against objects in the basket l5. 1
As may be most clearly seen in-Fi'gsi 'fiand 7',
each of the spray devices 36 consists oiv a tube 38 having at its lower end a sleeve 39 adapted tofit' snugly over a tubular outlet port 40 onxthe' manifold arm 30. Each sleeve 39 has L-shaped slots 4| disposed to receive projections. 3% on each port 49; to establish; a bayonet; type: of. j ointby ,which the spray devicesrfiermay be; quickly-t and easily i'andsecurelyattached'to or removed fromithe manifold arm 39.
-- -Preferably, I provide theaupper end of each of the tubes 38 with a pair of projections) to enter l- ,-shaped slots 491110243845 to establish bayonet joint connections: by which thecaps dilmaywbe easily detached from ;the spray, devicesto' permit them-to be thoroughly-cleansed;- l V The manifold arm 31; extends substantially through themidd'l'e. zoneiofthe: chamber l2 and is substantially wider than the arm fill'but is of lessvthickness; The arm 31 is formed" with a 'pluralityof orifices disposed to directjetsoilwash water upwardly against objectsin that-basket l5.

said unit comprising Va.manifold including azpair of spaced, parallel hollow arms interconnected At 64, I have shown the riser as indicative of the wash water delivery system. The riser 64 has an elongated mouth 65 disposed below the track 63 and adjacent the side wall of the chamber 58. The mouth 65 has grooves 66 extending along its sides to receive inwardly extending ribs 61 on the manifold element 68 to establish a slida ble interlock between the mouth 65 and the manifoldri'element 68 so; thatfthfe manifold element 'GS -may' be slid endwise from-"or into the machine out of or into a position in which it is locked to and supported by the mouth 65 of the riser 64. The manifold element 68 has a series of tubularports 69 (see Fig. 9) offset to support the spray devices 36 between the conveyor 59 and the adjacent -side f the chamber 58.
