ficat1on,'re'ference being bad to the accom-- panying drawings.

It is the purpose of the present invent on to provide a machine of this character, which is simple, efficient and practical in construction.

The present construction of machine is especially adapted for use by average fam-' ilies, and operated by the force of water, which is to be boiling hot, and obtained front the ordinary kitchen tank or boiler, or from instantaneous gas heaters, thereby expediting washing all dishes as well as kitchen utensils, and at the same time facilitating the removal of grease.

In connection with a machine of this char acter revoluble baskets or cages, preferably one within theother are supported in a casing-or basin, and through the mediunr of relatively heavy streams of water, at diagonal opposite corners of the basin, the baskets with the dishes therein are revolubly driven. One of the streams of water strike certain of the dishes or plates on an angle, to insure imparting motion to the baskets, while the other stream of water strikes the dishes directf acting to cut'the grease and refuse from the dishes. In addition to these streams of water ejected from diagonally opposite nozzles, the basin contains a plurality of spray nozzles, ejecting sprays from various directions, to assist in washing the dishes. The various sprays or jets-of water operating from various directions act to wash cups, drinking glasses, knives and forks and the like. Some of these jets or sprays of water project from the upper sides of the upper and bottom portions of the sides of the basin,to facilitate in cleaning the various articles.

In connection with the revoluble baskets or cages, a plurality of small cages are used for the plates and saucers and thelike, and

these smaller cages are removably suspended on the revoluble baskets, and are designed to be made with as little obstruction to the water as possible, so that the washing fluid may thoroughly reach all parts of the dishes.

It is another purpose to insure sanitation,

and at the same time to provide an apparatus which can be installed in any family kitchen, the construction and arrangement of the basin and its top, being such that the water will not overflow and splash on the floor of the kitchen.

After the dishes have been thoroughl washed, the supply of water may be out off and the water in the basin may be drained off, and in this case the dishes may be allowed to remain in the baskets within the basin, until they dry, and if necessary the dishes may remain in the machine until they are needed.

It is the aim to construct thevarious baskets or cages and similar parts of galvanized iron, though other material may be used, for instance aluminum, or any other material. The supporting frame for the basin may be constructed of any suitable metal, preferably including angle iron legs, while the basin may be constructed of porcelain, zinc, though any other suitable material may be used.

, A suitable soaping apparatus may be used in connection with the present form of washing machine, and is designed to be coupled between the supply tank and the washing machine, so that when the hot water enters the soaping apparatus, the. water becomes soapy, for the purpose of cleansing the dishes. Additionally it is the aim to pro vide a. separate or bypass connection between the hot water supply and the basin, so that boiling hot water may enter the basin for rinsing the dishes, especially when the supply of soapy boiling hot water is cut off.

While are design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more prac-' .tical form for commercial purposes, the invention may be susceptible of changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed;

The invention comprises further features and combination of parts, as will be hereinafter set forth, shownin the drawings, and claimed.

In the drawings F igure. 1 is a side elevation of the improved dish washing machine constructed in accordance with the invention.

Figure 2 is a horizontal plane sectional view on line 2-2 of Figure 1.

riveted or otherwise secured to the legs.

The dish washing machine also includes a suitable receptacle, casing or basin, which, though it may be any suitable shape preferably as shown, fits within the reinforcing strip 3 and rests upon a bottom member 3, which is supported on the angle reinforcing piece 4. The bottom may beconstructed of any suitable material, preferably wood. The basin may be constructed in any proportions or may be any convenient shape or configuration, and the side wall thereof adjacent its upper and lower parts has corrugations as indicated at 5, for the purpose of strengthening the wall of the basin.

The basin has its upper margin provided with a rolled bead 6, there being a suitable cover 7 This cover is designed to conform.

to the contour of the basin and isprovided with a marginal flange 8 overlying the annular head 6. The cover also includes an additional depending annular flange 9, which telescopes within the basin, and which together with the flange 8 prevents the water from escaping and splashing the floor of the kitchen.

Preferably the cover 7 comprises two sec tions 10 and 11. In the present instance the basin as well as the cover have rectangular sides and arcuate sides. The section 10 of the cover is hingedly united to .the rectangular side of the basin as shown at 12, while the section 11 of the cover is hingedly con nected at 13' to the section 10, thus it will be-seen that when it is desired to open the cover, the section 11 is first thrown back upon the section 10, then the section 10 1s raised.

The bottom of the basin has a centrally located pivot post or standard 14, and 15 and 16 denote dish receiving baskets or receptacles, which are revolubly mounted'upon the centrally located post or standard l t. The bottoms of these baskets or cages consist of the central hubs l7 and 18, from which radial arms 19 extend. These arms at their outer portions terminate in .upwardly and outwardly inclined portions 20, which are connected by the rods 21. These arms as well as the rods may be any suitable construction, preferably galvanized iron or aluminum, and may be any suitable diameter in cross section, or any suit-able of the basket or cage 15.

length. The arms 19 and the upwardly and outwardly extending parts 20 are connected by means of suitable Wire mesh, which act to support the dishes, knives and forks and the like. It will be noted that the revoluble baskets or receptacles are polygon shape, and supported upon the rods or pieces 21 are small wire mesh cages 22, which are designed to contain various dishes, such as dinner plates, dessert dishes, saucers and the like. Various knives, forks, spoons and the like may be supported on the bottom of the outer revoluble basket or receptacle, so as to be thoroughly cleansed by the hot soapy water. Rising upwardly from the radial arms 19 of the inner revoluble basket or receptacle are supports23, the upper parts of which are constructed of open work, such as wire material of a good size or substantially open mesh, and are designed to support cups, drinking glasses and the like, while they are being cleansed. The upper ends of these supports may be any suitable shape, preferably to conform to the interiorcontour of the cups or drinking glasses, so as to hold the same rigidly in place, while the cage or basket is revolving.

The centrally located post or standard 14 is removably mounted in a boss 24, by means of a pin 25, the removal of which permits the standard or post to detach. The upper end of the post or standard has an annular race-way 26 for the reception of anti-friw tional bearings 27 which are engaged by the centrally located upstanding sleeve 28, which rises centrally and vertically from the center I The central portion of the inner basket ,or receptacle has rising from, its hub 18 a tubular post or standard 30, which telescopically fits the standard or sleeve 28, so that the lower portion of the standard or post 80 may engage the anti-frictional members, for free revoluble movements.

The upper end of the hub 17 has a race way 31, which is engaged by the anti-frictional elements 32. These elements 32 are engaged by the lower end of the bore of a tubular standard or post 28, which rises from the central portion of the basket or receptacle 16. The upper end of the tubular standard or sleeve 28 terminates in a handle 34:, which may be grasped by the hand of the operator, for the purpose of lifting the basket or receptacle 16 from the machine.-

The upper end of the tubular standard or .post 30 also has a handle 35, by which the basket or receptacle 16 may be lifted from the basin. It is obvious that by removal of tlfe pin 25, the centrally located standard or post 14 may be detached from the bottom of the receptacle or basin, thereby permitting the basin'to be used for washing any heavy iron ware and kitchen utensils.

The pipe 36 is designed for connection to Marsala a kitchen tank or boiler or any other suitdishes.

able water supply, and is communicatively connected at 37 to the casing 38 of a soaping device. Mounted for revoluble'movement in the casing 38 is a soap carrying element 39 comprising a shaft 40, which has thrusts bearing 41 on the wall of the casing. The hub 42 of the-soap carrier is mounted to rotate with the shaft 40, and projecting radially from'the hub are cage blades 43, each carrying a bar of soap 44.

The pipe 36 has a valve 55, for the purpose of cutting off the supply of hot water to the soaping device. Connected to the casing 38 of the soaping device is a pipe 56, which in turn connects to the basin of the dish washing machine, and is provided with a valve 57, for cutting off the supply of soapy water from the soaping device to the washing machine. The by-pass pipe. 58 is connected to the ipe 36 between the valve and the tank, boiler or other water supply, and is in turn connected to the. pipe 56.

between the valve 57 and the basin. The by-pass pipe 58 has a valve 59, so as to control the boiling hot Water through the bypass pipe. Upon an inspection of the draw: ings, it is obvious that closing the valves 55 and 57, and opening the valve 59, boiling hot .clear water may enter the basin of the dish washingmachine, for the purpose of rinsing the soapy water, not only from the interior of the basin, but also from the After the dishes have been thoroughly rinsed, the supply of water to the basin may be cut off entirely, the basin thoroughly drained, and the cover of the basin subsequently removed, in which case the dishes may dry, it being unnecessary to revolve the revoluble baskets for the purpose of drying the articles.

It is also obvious that when the valve 59 is closed, and the valves 55 and 57 open, the

- water is thoroughly soaped, and is transmitted to the basin of the washing machine.

The pipe 56 passes. through the wall of the basin, there being a fluid tight joint 60 at the point where the pipe enters the basin, and is connected to an upstanding pipe 61. The pipe 61 has a lateral short pipe 62,

which may be any suitable length, and it is 1 provided with a flexible joint 68, with a.

movable pipe 64. The pipe 64 constitutes a tubular arm, which terminates in any suitable form of nozzle 65, preferably of the.

spray type. This tubular arm may be set at any suitable angle relatively to the dishes carried by the revoluble baskets, and the force of the spray or jet of Water is suflicient to impart movement to the baskets on the interior of the basin of the washing machine. In fact the tubular arm 64 may be moved to assume different angular positions, in order to direct the jets of water at different anglestoward the dishes, thereby regulating angles of substantial degrees, the speed of the baskets may be increased.

The pipe 61'merges into a horizontally disposed pipe 66, which may extend in any suitable direction, preferably diagonally across the bottom of the basin, and merges into an upstanding pipe 67. This pipe 67 terminates in a nozzle 68 particularly adapted for directing a heavy jet of water directly toward the dishes, acting materially to cut the grease and refuse from the surface of the dishes. Adjacent where the pipe 67 unites with the pipe 66, a spray pipe 69 is connected, and the jets of water from this pipe are directed upwardly at angles to the dishes carried by the revoluble baskets. These revoluble baskets are designed to be constructed so that there would be as little obstruction to the water as possible. Connected at 70 to the upper part of the pipe 61 is a spray pipe 71 provided with jet openings 72, whereby a plurality of jets of water may be directed downwardly upon the dishes. The spray pipes 69 and 71 are disposed at the bottom and top of certain of the sides of the basin. It will be noted that the sprays or jets of water are directed from various angles, toward the dishes carried by the revoluble baskets, and act materially in washing the dishes.

It is obvious that the upstanding post or standard 14 on the bottom of the basin of the dish washing machine may be detached, permitting heavy iron ware to be placed in the basin, to be washed. The superimposed revoluble basket 16 may be removed from the lower basket 15, whereby various utensils may be washed in the basket 15.

The various valves, particularly valves 55, 57 and 59 are designed to be of the ordinary construction, and purchased from stock valves, thereby substantially reducing the cost of manufacture.

It is to be understood that the basin of the dish washing machine may be any diameter, any depth, and constructed of any suitable material. The same is true in regard to the casing of the soaping apparatus. While the inner and outer baskets are shown as having wire mesh work or wire fabric, it is obvious that the radial arms of the haskets may be connected by small rods, or may have any other suitable means to support the dishes in the baskets. Furthermore it is obvious that any gauge of mesh work or wire fabric may be used. In fact the open work wire fabric may be any suitable size, so as to provide as little obstruction to the water as possible. While the drawing illustrates the soap carrying arms of the propeller as being constructed of wire hold bars of soap. The illustration in this regard is simply the conventional idea of mounting bars of soap on the blades of the propeller. For this reason it is obvious that the blades may be constructed otherwise than shown, so as. to support the bars of soap.

While there has been disclosed in the drawings and in the specification wire mesh or fabric forming the walls of the inner and outer baskets and on the holders for the dishes, it is obvious that the wire mesh or fabric can be dispensed with, and the dishes held in the holders. by the wire frame of the holders at one or two points. In thisway the dishes are exposed to the full force of the water. The dishes will be-held in position due to the high speed of the basket owing to the centrifugal force. Also it is to be noted that there has been two baskets shown in the drawings and described, but it is obvious that any number of baskets may be employed. In fact in addition to the inner and outer baskets as shown, an extra center receptacle (not shown) may be mounted in the same manner as the inner basket 16, and this additional basket or receptacle (not shown) may receive knives, forks and spoons. Furthermore if deslred,

the inner receptacle may be used without the pedestals, and in this case the cups and drinking glasses may be disposed in the receptacle or basket 16, or in the additional receptacle or basket (not shown), which may, or may not have walls of wire mesh work, with the openings of the cups and drinking glasses facing downwardly, so that such articles may be thoroughly cleaned and washed. The basin in which these receptacles are revolubly mounted may be macleany proportion, in fact it may be made longer or shorter, preferably the latter, and

may be made shallower. The driving spray nozzle 65 is capable of being adjusted universally, and furthermore the various other sprays and nozzle may be otherwise arranged and shown. It is obvious that the water is discharging from the basin all the time the dishes are being washed, unless the drain is cut off, which drain may be provided with a valve (not shown) for cutting off such 'Water. In view of this it is obvious thatthe dirty water does not at any time touch the dishes after once being sprayed thereon, as clean hot water at all times comes in contact with the dishes. Furthermore while there may be any number of sprays used, above and .below, there are two sprays shown'on opposite sides of the driving spray, one spray above, and one below, directing the various jets in all directions, in order to thoroughly clean the dishes. The

'driving spray or nozzle directs the water substantially toward the center of the dishes, as the receptacle rotates, While the sprays on opposite sides strike the dishes at the top and bottom. I

The invention having been set forth, What is claimed as being useful is: i

1. In a machine for the purpose indicated,

a basin, a substantially centrally disposed 3. In a machine for the purpose indicated,

a basin, dish supporting baskets mounted for revoluble movement in the basin, a plurality ,of means arranged at intervals and carried by the side walls of the baskets,

each to carry plates constituting blades, with which a jet of water may impinge, to insure imparting movements to the baskets, the construction and arrangement of the baskets being such as will permit the baskets to rotate independently of each other, so that one may travel at a greater rate of speed than the other, and a pair of nozzles connected with a water supply for directing jets of water at anglesto the dishes, to impart revoluble movements to the baskets, said nozzles being adjustable, for varying the rotating rate of speed of the baskets.
