  • the sidewalls are hollow and open at the bottom to emit P UNITED STATES PATENTS stacking of a plurality of superposed trays, for storing up the 1,484,291 2/1924 Blakeslee 211/41 dishes, by causing flanges of an underlying tray to fit into the 2,538,233 1 /l 951 Brandstrom 312/242 corresponding hollow walls of the tray above.
  • the present invention relates to dish trays or racks of the type used for transporting and storing up dishes, flatware and utensils, and also for washing these items in dishwashers.
  • the present invention more particularly relates to trays or racks adapted for use in automatic dishwashers comprising a series of separate treatment stations corresponding to thevari-- ous operations contemplated for'washing, rinsingand drying the dishes.
  • these stations are disposed serially and mechanical driving means are provided for automatically transferring a plurality of these trays or racks from one treatment station to another, 7 i
  • Machines of this type are advantageous in that they permit of automatically washing a great number of dishes, flatware or other kitchen utensils. However, they are objectionable in that washing solution and/or water is detrimentally splashed from one treatment station to another.
  • the very dirty water present at this station is most likely splashed into the adjacent washing station.
  • the passage of the dishes through the washing station may cause washing solution therein to be splashed into the next prerinsing station.
  • baffle means or curtains on certain known machines which are arranged so as to reduce the water or washing solution from splashing from one treatment station to another.
  • these means are not capable of completely eliminating this inconvenience.
  • a dish tray or rack which eliminates completely the incon-' venience set forth hereinabove.
  • Such a tray is also arranged with a view to facilitate the dish handling and'storing opera tions, while reducing the risks of breaking and/or damaging the dishes during these various operations.
  • Two of its sidewalls carry on their upper edges a pair of projecting or upstanding flanges, plates or cheeks adapted to act as screen means to prevent the splashing of wash water or rinsing water from another treatment station of the dishwasher, provided of course, that these two projecting flanges are disposed normally tothe axis along which the tray isdriven in the corresponding dishwashingmachine.
  • FIG. 1 is a perspective view showing a dish tray according to the present invention
  • FIG. 2 is a fragmentary sectional view of one of the sidewalls of this tray
  • FIG. 3 is a diagrammatic elevational view showing the use of a tray according to the present invention in an automatic dishwasher comprising a plurality of successive treatment stations;
  • FIG. 4 is a diagrammatic perspective view showing the superposition of a plurality of dish trays according to the present invention, before stacking same; 6
  • FIGS. 5 and 6 are fragmentary sectional views illustrating two trays superimposed. according to two different stacking methods.
  • FIG. 7 is a fragmentary section taken along the lines 7-7 of FIG. 6.
  • the dish tray designed in accordance with the present invention comprises a pan 1 of suband having a square horizontal section.
  • the bottom of the tray comprises a gridlike structure 2 including crossed bars. This bottom is also formed with notches or apertures engageable by drivers 3 equipping an automatic dishwasher 4, for example, of the type shown diagrammatiple, by being moulded integrally with the tray structure. Howderlying tray to fit into corresponding hollow walls of the next tray above.
  • the cavities formed in two of its'sidewalls comprise inner ribs in order to limit the fitting of these walls on the flanges of a similar underlying tray, if the angular arrangement of the two superposed trays is such that these sidewalls overlie the flanges.
  • the upper tray is kept in a somewhat raised position with respect to the position it could occupy above the same tray underneath, provided that it is placed in a different angular position, i.e. shifted by 90, with respect thereto.
  • the projecting flanges formed on the dish tray of the present invention have a twofold function: firstly, they act as screen or bafile means preventing the splashing of water or lye or soda solutionfrom one treatment station to another, and secondly they afford two different methods of stacking up the dishes contained in these trays, thus reserving the possibility of taking due account of the height of the particular articles contained in the trays.
  • these lateral upstanding flanges are preferably detachably secured thereto as shown in FIG. 2.
  • Each flange 6 can be secured in this case by means of screws 7 or any other suitable assembling members. 1
  • the various walls 5 and 8 of the tray are hollow and the resultinginner cavity is open at the bottom.
  • the projecting upstanding flanges 6 are so shaped and dimensioned that they can fit into the two opposite walls of a similar tray.
  • these projecting flanges afford two different methods of stacking up the dish trays of the present invention. 1
  • the flanges also act as screen or-baffle means when the dish trays of the presentinvention are utilized in an automatic dishwasher inorder to prevent water or lye solution from splashing from one treatment station to another.
  • the trays according to the present invention should be disposed on the transport path of the dishwasher such that their sidewalls 5, which are formed or provided with the projecting flanges 6, extend normally to the direction of travel of the trays.
  • these projecting flanges dueto their height, act as screen members extending on either side of each tray and very efficiently prevent the splashing of water or lye solution from one treatment station to another.
  • the function of these projecting flanges 6 is clearly illustrated in FIG. 4 of the attached drawings.
  • the screen or baffle means thus fonned positively prevents any splashing of water from the first washing station 12 towards the second washing station 13. They also prevent similar splashings from this station 13 towards the rinsing station 14.
  • the projecting flanges 6 have another very important function. They permit a choice between two different methods of stacking up the trays of the present invention for storing the dishes and like articles. In this respect, it may be emphasized that for reasons of efficiency and economy it is desirable to have the possibility of keeping the dishes and like articles in the trays used for washing them.
  • This storage method is particularly advantageous in the case of glasses, cups, saucers, bowls and substantially all hollow articles, outside soup-tureens, vegetable dishes and soup plates.
  • the tray according to the present invention since the lateral upstanding flanges 6 carried by two opposite sidewalls thereof permit two different stacking methods, namely a first stacking method for washed articles having a normal height, and another stacking method for higher-than-normal washed articles.
  • the cavities formed in the two opposite sidewalls 5 of each tray are formed with integral ribs 15 adapted to limit the fitting engagement between the inner surfaces of these walls and the projecting flanges 6 of a similar underlying tray when a plurality of these trays are stacked upon one another.
  • these ribs are not provided in the cavities formed in the other walls 8 of each tray.
  • the inner ribs 15 will bear on the top of these flanges.
  • the bottom 2 of the upper tray lb is kept at a certain relative spacing above the upper plane of tray 1a, i.e., the plane containing the upper edge of its walls 8.
  • the projecting upstanding flanges 6 permit two different tray stacking methods, according to the height of the articles disposed therein.
  • the flanges were detachably mounted, as illustrated in FIG. 2, it is possible to provide a plurality of sets of the flanges, these sets differing by their vertical dimensions.
  • tray or rack can be adapted to different service conditions.
  • end flanges can be either modified or eliminated at will.
  • a dish tray for transporting and storing up any dishes, flatware and utensils, and for washing same in a dishwasher, comprising:
  • a pan substantially parallelepiped in configuration, formed with sidewalls and an apertured bottom;
  • said sidewalls being hollow and open at the bottom and complementary to the top of said projecting flanges in order to permit the fitting of said sidewalls on the pair of projecting flanges of a similar tray when a plurality of said trays are stacked up in superposed relationship.
