To all whom it may concern:

Be it known that 1, THOMAS W. CRAVEN, citizen of the United States, residin at Fairfield, in the county of Solano and tate of California, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

This invention relates to an improved washing machine, and the principal object of the invention is to provide a washing machine which can be used for washing dishes or for; washing clothes.

Another object of the invention is to provide an improved means for directing the circulationof water through the tank.

Another object of the invention is to provide an improved type of cover which 1s provided with a deflecting plate WhICh Wlll assist in directing the circulation of the water.

Another object of the invention is to provide an improved propeller which is so constructed that it may be used for directing the circulation of the water and also causing an air current to be driven through the tank.

Another object of the invention is to provide an improved rack for holding the dishes in the tank.

Another object of the invention is to provide improved supporting bars for the dishes which are so constructed that their corrugated portions may be caused to he in either a horizontal or vertical plane.

This invention is illustrated in the accompanying drawings wherein Figure 1 is a side elevation of the improved washing-means; Fig. 2 is a longitudinal sectional view through the improved washing machine; Fig. 3 is a top-plan v1ew of one end portion of the dish-supporting rack with a dish shown in dotted lines; Fig. 4 is a perspective view of one of the dish-supporting bars.

The tank 10 comprises a body portion which is substantially oblong in the form shown and which is supported by the forward supporting legs 11 and rear supporting legs 12. The tank has been shown oblong in the drawing, but it is obvious that this'tank could be formed either square or any other suitable shape according to the desires of, the person manufacturing the washer. The upper-end ortion of the tank is provided with a flare mouth 13 which flanges 17 which rest upon 27 has its blades forms a seat for the cover 14. End lips 15 are provided so that catches 16 may be pivotally connected with the tank for removably holding the cover 14 in place. This cover 14 is provided with side and end the supporting mouth 13 and is also provided with a tongue 18 at the rear end which extends into the tank as shown in Fig. 2 to direct the circulation of the water through the tank.

A vent 19 extends upwardly from the cover 17 and is provided with a flared mouth 20 so that steam may escape from the tank ,and fresh water may be poured into the tank Without it being necessary to remove the cover. The rear-end portion of the tank which is opposite the curved forward end wall 21 is formed into a housing 22 which extends beneath the tank and has its lower end portion connected with the tank by means of the drain guide 23 positioned in alinement with the outlet 24. This outlet 24 is provided with a removable plug 25 so that when desired the plug can be removed and the water permitted to drain from the tank. If desired, a suitable valve could be provided for the outlet in place of the screw plug, shown in Fig. 2. The legs 12 which support the rear end of the'tank'extend along the rear wall of the housing 22 and have their upper ends connected with a bearing 26 in which a shaft 27 is rotatably mounted. The propeller 28 which is rigidly connected with the inner end of the shaft 29 provided with fiat inner side portions which extend close to the rear Wall of the housing 22 and substantially parallel therewith, and have their outer side portions curved to extend away from the rear wall of the housing. This construction is clearly shown in Fig. 2. By having the propeller constructed as shown, the water is driven through the tank with a great deal of force and will thus rapidly clean the dishes in the tank.

A stub shaft 30 extends from the legs 12 in alinement with the bearing 26 and is provided with a reduced outer-end portion that the handle 33 can be connected with the gear wheel 34. A set screw 36 is provided so that the handle can be rigidly held in place to cause the gear wheel with which it is connected to turn with the handle.

A frame is removably mounted in the bottom of the tank and comp-rises the side bars 37, end bars 38, and sup orting feet 39. The feet 39 are spread a su 'cient distance 10 to cause the frame to fit nicely in the bottom of the tank without any longitudinal or transverse sliding movement after being put in place. It will therefore be seen that there is no danger of this frame moving out of the set position and causing the dishes to fall out of place. The dishes are therefore protected from any danger of being broken in the tank. Fingers 40 are carried by the side bars 37 in sets, as shown in Figs. 2 and 5 so that dish-supporting bars may be removably and adjustably connectedwith the frame. These dish-supporting bars 41 are each formed from a strip of relatively heavy rod metal, such as heavy wire which is rustproof, the wire being crimped to form the dish-engaging arms and pockets shown in Figs. 3 and 4. The end portions of the wire are bent to form the

eyes

42 and 43 which are rectangular and extend at right angles to each other. By having the eyes positioned at right angles to each other, one of the eyes will be positioned between the fingers 40 at one side of the frame and the eye at the op posite end of the dish-supporting bar will extend about the fingers at the opposite side of the frame and thus cause the dishsupporting bars to be securely held in the des1red position with the dish-engaging arms extending either horizontally or ver- 40 tically.

The operation of this device is as follows: After the dish-supporting frame has been put in place and the dish-supporting bars arranged in the desired manner, the dishes are put in place with the edges of the plates extending between the arms of the bars so that they will be held on edge with their faces turned toward the sides of the tank.

he cups are laid flat upon the bars, their open ends extending toward the housing 22 and their bottoms engaging one of the bars which extends'vertically as shown in Fig. 2. The hot water and a cleaning composition are then put in the tank until the tank has been filled with a sufiicient amount of hot water and the cover is then put in place and secured by the catches 16. If it is desired to use very hot water which would be liable to scald the hands by the action of its steam when the cover is being put in place, the cover can be put in place first and the hot water poured into the tank through the vent 20.

After the tank has been filled with water,'

the handle is placed upon the gear wheel 34 and then turned so that the propeller will be rotated and thus cause the water to be driven rapidly along the dish-supporting frame toward the forward end of the tank. When the current of water reaches the curved wall of the tank, it moves upwardlyand returns to the rear end of the tank until it strikes the deflecting plate 18. This will cause the current to be driven downwardly toward the dishes and it will thus be seen that the water will have a very complete circulation through the dishes. It should be also noted that the drain guide 23 will cause part of the water to move upwardly along the lower edges of the dishes and thus cleanse the por- 8e tions of the dishes which extend beneath the supporting bars 41. After the handle has been turned a sufficient length of time to cleanse the dishes, the hot water can be drained out through the outlet 24 and clear water poured into the tank through the vent 19. The handle is then turned to cause this clear water to circulate through the tank and this will thoroughly rinse the dishes. After the'dishes have been rinsed, the rinsing water is drained off and the handle is then trans ferred to the gear wheel 31 and turned to cause the propeller to drive a current of air through the tank so that the dishes will be dried.

It will thus be seen that a dish-washing machine has been provided in which the dishes can be placed and then washed, rinsed, and dried before it is necessary to remove the cover. The drying process drives all the steam out through the vent 19 and therefore when the cover is removed to move the dishes from the tank there is no danger of the 'hands being scalded by steam in the tank. Itis, of course, obviousthatwhen drying the dishes, the outlet 24 will be left open so that all of the water can drain out of the tank and air can be sucked into the tank and driven through the tank by the propeller.

What is claimed is:

1. In a washing machine a frame, engaging means upon opposite sides of said frame, and article supporting bars removably connected with said engaging means, each of said bars being provided with article engaging means and having its end portion provided with eyes extending at right angles to each other, the eye at one end of each of said bars being positioned between its engaging means and the eye at the opposite end being positioned about its engaging means.

2. In a washing machine, a supporting frame, engaging fingers forming part of said frame, supporting bars carried by said frame and having their end portions bent to form eyes for removably connecting said bars with said fingers, said eyes extending at substantially right angles to each other whereby one of said eyes of each bar will extend about its fingers and the eye at the 130 opposite end of the bar will extend between its fingers to releasably hold the bar in either a horizontal or a vertical position.

3. In a washing machine a supporting frame, fingers carried by said supporting frame, and supporting bars releasably engaging said fingers, each of said bars being formed from a strip of material bent to form article-engaging means and having its end portions bent to form eyes extending at substantially right angles to each other,

one of said eyes being positioned between its engaging fingers and the eye at the opposite end of the bar passing about its engaging fingers.

In testimony whereof I aflix my signature in presence of two witnesses.
