mum iHHHHHlI a re THOMAS E. MURRAY, on NEW YORK, as.

DISH-WASHING MACHINE.-

Application filed May 28, 1915.

7 '0 all whom it may concern:

Be it known that I, THOMAS E. MURRAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Dish-Wash-.

ing Machines, of which the following is a specification.

The invention relates to dish-washing machines of the type wherein the dishes are subjected to liquid projected against them while supported on a horizontal rotary per' forated table within a suitable tank or receptacle. The dishes are introduced through an opening in the wall of the tank, and thence are caused to descend an inclined chute to the table. As they are carried around by the table, they are subjected to the successive action of liquids contained in compartments in the lower part of the tank, and then to streams of liquid led into the tank through suitable pipes from'anoutside source-after which they-pass to a delivery opening below the receivlng opening. The

space above the table'is separated by the chute and a suitable curtain depending from the cover into two compartments, so that the liquids projected against the table from the lower compartments do not mingle in the upper compartments, and other suspended curtains prevent the liquid projected into the respective upper compartments from passing into the chute or to the delivery opening. Deflecting means on the cover throw back the liquid after it has'passed upwardly through the perforated table.

In the accompanying drawings, Figure 1 is a plan view of my dish-washing machine, with the cover removed. Fig. 1? is a plan view on a reduced scale of the under side of the cover.- Fig. 2 is a cross section on the line 2, 2 of Fig. 1. Fig. 3 is a section on the line 3, 3 of Fig. 1. ig. 4 is a detail section on the line 4, 4 of Fig. 2. Fig. 5 is a similar section on the line 5, 5 of Figs. 2 and 6. Fig. 6 is a horizontal section on the line 6, 6 of Fig. 5. Fig. 7 is a section on the line 7, 7 of Fig. 1.

' into two compartments A, B by the diametral partition 9. Above the partition 9 is a horizontal rotary dish-receiving table 10, formed of wire-netting, supported on a ring Specification of Letters Patent. 7

plnion 13, with which engages a worm carried the shaft 14 of an electric motor 15. II11lh1I Way,tl16 table 10 is rotated.

1g. 3, is a supply i e for water rovlded with two branch gi gles 17, 18, wl iich enter the tank, as shown in Fig. 3. Said branch pipes are perforated, so that from pipe 17 ets are delivered downwardly, and from plpe 18 upwardly, upon the table and dishes thereon. This water descends into the compartments A, B in the bottom of the tank. In compartment A is a partition 19, Figs. 2,5 and 6, forming with the wall of the tank a sub-compartment C, which communicates with the waste pipe 20. In partitlon 19 is a valve 21 operated by a handle extending through the tank wall, by opening which valve water is permitted to escape to pipe-20 from both compartments A, B; In partition 9 is an opening 22, .Figs. 2 and 4, whlch permits the liquid in one tank compartment to flow over into the other. An overflow from compartment B is also provided in partition 19 by making a notch or recess 23 therein, as'best shown in Fig. 5.

On the motor shaft 14, which extends through partition 9, are mounted four beater-arms 24, two in each compartment A, B. Said arms have cups on their ends, and when in revolution throw the liquid. in said compartments upwardly against the rotating perforated table.

In the tank wall 'are two openings, namely, an upper opening at D, Fig. 2, and a lower opening at E, Fig. 3. The bottom of the lower opening E registers with the upper surface of the rotary table 10. From the upper opening D an inclined chute 25 descends to the said table. The upper portion 26 of the bottom plate of said chute extends outwardly beyond said opening, as shown in Fig. 2. The outer side wall 27 of the chute 25, Fig. 1, lies tangential to the This side of the chute is, therefore, completed by a partition 29 which depends from the under side of the cover 30, the lower edge of said partition registering with the upper edge of wall 28. l

Depending from the bottom plate of the chute and near its lower edge is a depending partition 33, shown in full lines and in elevation in-Fig. 3, and in dotted "lines in Fig. 1. Outside of the opening E is a tray or platform 31, the outer side wall of which (32, Fig. l) is in prolongation of and substantially tangential to the lower portion of the cylindrical tank wall and also parallel to partition 33. After the dishes have been carried around by the rotating table and come in front of openingE, they meet the partition 33, and thus are prevented from being further carried. The resultant effect of being transported by the table against the inclined partition 33 is that they are caused to move outwardly in the directionof the arrow G, Figs. 1 and 3, and so through opening E and to the delivery tray 31.

Centrally secured to the under side of the cover is a tubular pillar 34. The upper portion of said pillar above the chute 25 has a depending flange 35, to which is secured a curtain 36 which extends across the lower ortion of the chute 25 and prevents splashmg of liquid thereon. The vertical edge of the partition 29 is secured to said pillar.. The upper portion of the Wall of said pillar is curved over, as shown at 37, Fig. 2, so that water thrown upward by the beaterarms 24 will be deflected downwardly upon the dishes. On the under side of the cover is a cross-bar 38, Fig. 2, which serves to support a curtain '39, the lower edge of which approximates the table 10. A similar curtain 40, Fig. 2, is suspended from the chute 25 and also at its lower edge approximates the table.

In order to prevent the water thrown up by the beater-arms 24 from being projected elsewhere than on the under side of the table, I provide a U-shaped guard plate for each beater, the outer free arm of which is shown at 41. The guard plates rest on the bottom of the tank and are secured at their inner arms. to bars 42, 43, respectively disposed in the compartments A, B.

The upwardly projecting arms 41 of the beater-guards are preferably to be set at i different angles, so that the liquid thrown up by the heaters may reach different portions of the table. Thus in Fig. 1 the outward bending of the'arms 41 of two of the guard-plates is indicated at 45.

The liquid in the tank may be heated by a gas-burner 44 suitably supported under the bottom of the tank.

The operation is as follows: The dishes introduced through the opening D and upon the chute 25 successively slide down said chute in the direction of the arrow F in Fig. 1. After passing under the curtain, they arrive upon the horizontal'rotary table 10,

.upon by the liquid in said last-named compartment which is also thrown up by beaters 24. This liquid may be hot water. Then -the dishes pass between the jets of water projected from the pipes 17 18, and finally after traveling under the curtain 40 meet the partition 33, which, as already explained, causes them to travel upon the tray 31, from which they are finally removed. The curtain 39 serves to prevent liquid thrown into the tank space above one compartment passing into the space above the other. The curtain 40 serves to prevent liquid in compartment A from escaping into the delivery space. above tray 31.
