To" all whom it may concern: l

Be it known that 41, FRANK E. WoLooT'r, a citizen`Y of the UnitedStates, resi-ding at Hartford, inthe county of Hartford andv the cleansing 'liquid when violently agitated yduring the .process of' washing will not Splash out around the edges and wet surrounding objects to the annoyance of the v users, and at the same time, of course, it is desirable that the covers should be as light in .weight and cheap in construction as possible, and should open and close easily after long use as well as when new. It is somewhat difficult to make light, cheap and durable covers which will be tight and yet easily opened and closed.

. The object of this invention is to provide a construction for the tanks and covers of such apparatus which will render it unnecessary to use extreme care and incur large expense' in manufacture in order to have light, cheap and easily opened covers fit water-tight in the tanks and prevent the escape of water when it is agitated for washing the contents of the tanks.

This object is attained by providing the upper edges of the tanks with ledges and the covers w1th baling lips which fit together in such manner that the passage between' them for any-water -which attempts to escape is so circuitous that, none can lpass out, and also shaping the tank walls below the ledges so that water thrown up by the operation of the machines will be directed away from the joints between the covers and the tanks.

In the accompanying drawings Figure 1 shows a view of a dish washing machine with the tank and cover constructed according to thisl invention. Fig. 2,.on much larger scale, shows a section of a portion of the tankand cover illustrating the 'manner in which they it together. Fig. 3 is a view similar to that shown in Fig. 2 with a cover of modified construction lifted from the tank.-

The tanks 1 of this type of apparatus are commonly made of sheet metal bent, Vfolded or stamped to the desired shape, usually rectangular. The tank shown is supported on angle-lrcn'legs 2. `In the embodiment of the lnvention illustrated the tank near its upper edge in the interior has a substantially horizontal seat 3 with a substantially vertical wall 5 below the seat. Of course these walls above and below the seat need vertlcal wall 4 above and a substantiallyV not necessarily be exactly vertical. The rim of the tank is curled over to form an ornamental stlening and finishing bead 6. Below the vertical wall beneath the seat is an inwardly extending ledge 7, and below this ledge the wall slopes outward to the full size of the main wall of the tank. This shape extends entirely around the tank and may be made by rolling the metal to the deslred conformation while in sheet form and before it is bent, folded or otherwise put together to complete the tank.

The cover shown is formed of two sheets of thln metal, a top sheet 8 and a bottom sheet 9. The `top sheet has its edge all around bent downward to form a flange 11 which lits loosely within the vertical wall 4 of the tank, and the bottom sheet is formed so as to have a downwardly extending lip 12 that loosely fits the vertical wall 5 of the tank, and an upwardly extending ange 13 that is soldered, brazed or otherwise fastened to the flange 11 around the top sheet.

. The lip 12 depends such a distance that it rests upon the ledge 7 when the cover rests upon the seat 3. If desired, the lip may be formed of a separate piece, as shown in Fig. 3. In this case the edge of the bottom sheet 14 is turned down and entered and fastened between two sections of the lip strip 15, the edge 16 of which is turned up and secured to the flange 11 that extends down from the edge of the topsheet 8. A filling piece 17 of wood or other suitable material may be placed inside the metal sheets before they are fastened together, for adding strength and durability to the structure, as shown in Fig. 3. The formation' of the bead at the and if it is filled withwood aids in preventing the wood from warping out of shape.

Such a cover as described may be made cheaply, lit is light in weight, and it iits the tank loosely so as to open and close easily, and yet when closed down on a tank thus shaped the only pathfor the escape ofwater is over the ledge, around and up back of the lip, across th'e seat and up and over the louter rim, a path so tortuous that no matter how violently the water in the tank is agitated none escapes. Furthermore by inclining the walls of the t'ank below the ledge the water which is .t thrown upward is directed away from' the `jQint between the cover and the tank rather than toward it.

The invention claimed is 1. A dish washing machine receptacle comprising a tank having its side walls shaped tov provide an inwardly extending cover Aseat below its upper edge and an inwardly extending ledge below said seat, and a cover fitting into the tank with its under surface resting upon said seat, said lcover having a lip that extends downward belo w the seat to said ledge.

2. A dish washing machine receptacle comprising a metal tank having its side walls shaped to provide an inwardly extendin cover seat and an inwardly extending le ge below said seat, and a. metallic cover fitted within the side walls of the tank with its under side adapted to rest on said seat and having a `folded lip adapted Vto fit the side walls and rest on said ledge when the cover rests upon said seat. Y

3. A dish washing machine receptacle comprising a tank having` an inwardly ex` tending cover seat below its upper edge, an inwardly extending ledge below saidseat and its side walls sloping outward and downward below said edge, and a cover loosely litting into the tank, said cover shaped to rest upon said seat and provided with a lip that extends below the seat and Yrests on said ledge when the cover rests on the seat.i i 4. A dish comprising a tank having its side walls shaped to provide a substantially horizontal cover seat-below its Vupper edge, and a cover loosely fitting into the tank, said cover shaped to rest upon-said seat. and fit the side walls of the tank above and also below said seat, the side walls of the tank below the bottom ofthe cover being extended inward beyond and closing the lower edge of 'of the tank.
