2 Claims.

My present invention relates to apparatus for I I washing dishes and the main objects thereof are the provision of improved apparatus for washing dishes; the provision of simplified apparatus for the cleaning of soiled dishes; the provision of apparatus for the purpose stated which is inexpensive to manufacture and is eificient in use; and such further objects, advantages, and capabilities as will hereinafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings and, while I have shown therein what is now regarded as the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not to be interpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof,

Fig. 1 represents a horizontal section taken substantially along the plane indicated by the line I-I, Fig. 2;

Fig. 2 represents a vertical section with parts shown fragmentarily;

Fig. 3 represents a vertical section approximately along the plane indicated by the line 3-3, Fig. 1; and

Fig. 4 represents ,a broken vertical section taken substantially along the plane indicated by the line 4-4, Fig. 1.

Reference will now be made in greater detail to the annexed drawings for a more complete description of this invention. The working parts of this construction are enclosed in a housing I and comprise the tub 2, the motor 3, and the pump 4. On the shaft of the motor there is a belt pulley 5 which is connected by a belt I to the pulley 6 mounted on the shaft 8 of the pump. On the inner end of this shaft 8 is an impeller 9 which withdraws water from the tub 2 and forces it around the pipe II] and back into the tub 2 in a direction to engage the edges of plates, saucers, and the like, stood up in the basket II. As shown in the drawings, the inlet end I2 of the fluid conduit is large and permits free access of water thereto, drawn in by the pump 9. The outlet end of the conduit I9 is elongated in a vertical direction but compressed in a direction at right angles thereto. Therefore, rotation of the impeller 9 forces the washing fluid through the conduit at an increasing rate and out against the dishes with considerable velocity.

A second pulley, indicated at I3, is mounted on shaft 8 and is connected to a pulley I4 by a belt I5. The pulley I4 is carried by a shaft I6 which has a pinion II at its inner end. The pinion I'I cooperates with a ring gear I8 on the under side of the basket I I in rotating the basket which is suspended on a plurality of pulleys I9 carried by the inner wall of the tub 2. The basket I I comprises a plurality of rings 20, 2|, 22 to which are secured a plurality of outwardly extending wires 23. These wires are connected at their inner ends to a ring 25, comparable to rings 20, 2|, 22, From the rings 23 and 25 rise a series of wires 24. The upper ends of these upright wires are connected to a ring 26 which forms an outside upper boundary of the basket. The upper outwardly extending wires 23 are comparable to the lower wires of the basket which, together with the rings 20, 2|, 22 and 25, form compartments for the reception of fiattish dishes, such as plates, saucers, and the like. Cups and other hollow ware can be placed on top of these upper wires 23, with their hollow sides facing the water stream so that they can be washed by water forced against them.

At the center of the tub is a cup 21 in which is supported a wire screen 21a having an opening facing the stream of water emerging from the pipe I 0 and striking the dishes in the basket II. The water which washes particles of food from the dishes carries them into the screen 25 which strains them out of the water, allowing them to collect in the cup 21 from which they may be removed. A valve controlled pipe 29 is provided for withdrawing the wash water from the tub 2. The washed dishes may be put out on the draining board 28 from which the wash water runs back into the tub 2. The tub 2 is shown as being provided with a cover 30.

Briefly stated, the operation of the machine is as follows. The dishes are placed in the basket II and hot water is put into the tub 2 until it covers the exit from the tub into the pump. The motor is then started and this drives the impeller 9, forcing the water out through the end of the water-carryingpipe I0 and against the dishes in the basket II. This basket is rotated slowly by the pinion I'I driven indirectly from the motor 3. After the dishes are sufiiciently washed, the motor is stopped and the dishes are removed from the basket and placed on the draining board.

It will of course be understood that the specific description of structure set forth herein may be departed from without departing from the spirit of this invention as set forth herein and in the annexed claims.

Having now described my invention, I claim:

1. In a structure for the purpose stated, a fixed container for the reception of a washing fluid, spaced supporting rollers mounted therein and adapted to rotate on their axes, free from contact with the bottom of the container, a basket supported on said rollers and adapted to rotate in said container, mechanism for rotating said basket in said container, said basket having an un obstructed central opening, a non-rotatable netting trap for detached particles centrally located in said container within said central opening and extending upwardly through said opening, and a pump having an inlet pipe and an outlet pipe connected to the container at separated points to withdraw the washing fluid therefrom and return it thereto at a velocity at least as great as the velocity of withdrawal, said trap having a longitudinally extending slot in its wall facing the return end of the outlet pipe.

2. A washing machine comprising, in combination, a container for articles to be washed, an article-holding basket supported therein for free rotation on rotatable means, said basket having an unobstructed opening in the bottom thereof, a fixed screen extending upwardl from the bottom of the container through the opening in the bot tom of the basket and having a vertical longitudinal slot in the wall thereof, the basket being rotatable about the screen and being provided with compartments for the reception of articles to be washed, said compartments being arranged approximately tangentially to the outer surface of the screen, means for withdrawing washing fluid from the container and returning it thereto at a point along the lateral-wall of the container, remote, in the direction of rotation of the basket, from the point of withdrawal, and means for causing operation of the withdrawing means, said last named means also causing rotation of the basket about the screen, the slot in the screen facing the water-return opening.
