HECTOR BABEZZANA, OF FLINT, MICHIGAN, ASSIGNOR 0F ONE-HALF TO AXEL A. CARLSON, OF FLINT, MICHIGAN.

WASHING-MACHINE.

Application filed June 17,

To all whom it may concern:

Be it known that I, Hno'ron RABEZZANA, a

subject of the King of Italy, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in VVashing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved washing machine which is especially designed for washing clothes, although, it is not to be restricted to this use.

The principal object of the invention is to provlde a washing machine of the centrifugal type, which is such that it will automatically wash and then dry the clothes in the same receptacle without removing the clothes.

Another object of the invention is to provide a washing machine of the above mentioned type which has means incorporated therewith for circulating either a hot or a cold cleaning fluid through the clothes.

A further object of the invention is to provide a washing machine provided with novel means for elevating the cleaning fluid to a point adjacent the upper edge of the container, which arrangement insures that the cleaning fluid will be effectively and uniformly distributed through the clothes or other articles in the container.

A still further object of the invention is to generally improve upon and simplify the construction of devices of this class by producing one which is extremely effective in operation, strong and durable, easy to repair and clean, and inexpensive to both the manufacturer and the user.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of the specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a central vertical sectional view, partly in elevation, of a washing machine constructed in accordance with my invention.

Fig. 2 is a top plan view thereof.

My washing machine comprises a stationary receptacle 1, supported by means of a Specification of Letters Patent.

1920. Serial No. 389,748.

suitable leg-structure 2. At its center the receptacle is provided with an upwardly ex tending tubular portion 3, the purpose of wh1ch will be hereinafter described. Disposed 1n the receptacle 1 is a container 4 for clothes or the like, the same being provided at its center with an upwardly extending, perforated tubular portion 5 which surrounds and is supported by the tubular portion 3 of the receptacle. The container is adapted for rotation within the receptacle, and 1t receives motion from a tubular drive shaft 6 which is joined to the tubular portion 5 and extends downwardly through the tubular portion 3, being supported at its lower end by means of the spindle 7. At its lower end, this drive shaft carries a disk 8, which is rotated by means of the shaft 9 whlch carries a driving-roller 10. It is to be stated here, that one end of the shaft 9 may be journaled in the bearing 11, so arranged that it is permitted to slide, making it possible to move the roller 10 closer to or farther away from the periphery of the disk 8 1n order to change the speed of rotation of the latter. Since the construction for accomplishing this result will vary, it is not thought necessary to show any particular construction. I also desire to mention here, that I do not wish to be limited to this particular type of driving means, because of the fact that other suitable means may be well employed. The upper end of the tubular drive-shaft 6 is internally screw-threaded, for a purpose to be hereinafter described.

It has been before intimated that I provide means for elevating and effectively distributing the cleaning fluid through the articles to be cleaned. To this end, I form the perforations in the tubular portion 5 in a continuous helical upwardl extending line and just beneath these per orations I place an endless helical internal lateral flange 25 which construction, as is obvious, will act as a water elevator and effectively distribute the water through the uppermost perforations which result is otherwise unobtainable. Emphasis is to be laid on this construction.

A removable cover 12 is provided for the clothes container. This cover rests on the upper edge of the container 4 and forms a closure for the notches 4 in the upper edge of the container. These notches form outlet openings for the water which passes therethrough and into the receptacle 1. To retain the cover in position, I make use of a screw-threaded plug 16 which extends through the apertured socket 13 and coacts with the screw-threaded portion of the tubular drive shaft 6.

.To direct a portion of the fluid back into the receptacle, and also to provide means for collecting a quantity of the fluid, I provide the receptacle at its upper end with a curved rim 18 which is increased in size at the right hand side of the receptacle as shown in Fig. 1 at 19. The bottom of this enlarged ortion is disposed below the upper edge of tlie receptacle. and serves to collect some of the cleaning fluid so that it may be directed through the pipe 20 back to the boiler 21 and a ain heated before being used over again. The fluid is supplied from the boiler 21 to the receptacle 1 by means of the pipe 22. In order to permit my device to be used for drying the clothes, I provide a drain pipe 23 by means of which all of the fluid may be drained from the receptacle 1. In case it is desired to use cold water for cleaning the clothes, I connect cold water supply pipes 24 and 24. to the pipes 20 and 22 respectively, there being valves 26 in these pipes to permit either the passage of hot or cold water into the receptacle. I desire to mention that the pipes 24 and 24* may also be utilized to supply steam to the receptacle 1 which may be used to an advantage in cleaning clothes.

The operation of the machine is as follows: Assuming that the top 12 has been removed, it will be seen that the first thing necessary to do is to place the articles to be cleaned in the container 4, whereupon the cover may be replaced and locked in position by means of the screw plug 16. After this, the receptacle 1 is supplied with hot or cold water or steam, as may be desired by means of the pipe 22. Then, the driving means is set into operation to rotate the clothes container 4. The fluid is carried upwardly through the perforated tubular portion 5 by the helical flanges 25 and passes through the perforations and into the clothes in the container, being discharged from the latter through the outlets 4 formed between the cover and the upper edge of the container. Due to the fact that the edge of the container is disposed above the edge of the receptacle, it will be seen that a quantity of the water or fluid will be deposited in the enlar ed portion 19 of the curved rim, and will be returned to the boiler 21 and reheated. On the other hand, some of the fluid will not take this course but will be directed downwardly by means of the rim 18 into the receptacle again, and will circulate through the clothes. After this operation has been continued for some little time, the Water will be drained from the receptacle by means of the pipe 23, after which the container will again be rotated at a good speed to dry the clothes.

It is desired to distribute the returning water in a uniform manner over the inner surface of the receptacle 1. By returning water I mean that water which has passed through the clothes and is being returned into the receptacle 1 to be used over again. In carrying out this feature I place a plurality of vertically disposed spaced ribs 27 in the receptacle.

From the foregoing description it will be seen that I have perfected an extremely effective clothes washing machine which is automatic in operation, washes, and also dries the clothes without removing them from the container in which they are placed. The construction of the machine is such that any or all of the parts may be readily disconnected for repairing and cleaning. Due to the arrangement of my machine, the passage of the cleaning fluid through the clothes will be retarded, consequently, the clothes will be more thoroughly cleansed. The device is extremely simple in construction and is inexpensive.

A careful consideration of the foregoing description taken in connection with the accompanying drawings will enable persons skilled in the art to which this invention relates to obtain a thorough understanding of the construction and operation of the same, therefore, further description is deemed unnecessary.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred form of the same, and that various minor changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. A washing machine comprising a sta tionary tub provided with a centrally disposed upstanding tubular imperforate part, an article container in the tub, being provided with a central apertured tubular part surrounding the first named tubular part and serving to permit passage of fluid from the tub between itself and the adjacent tubular part into the container, the latter being increased in diameter toward its top, and a cover for the container, the latter being provided with fluid escape openings adjacent v the tub between itself and the adjacent tubular part into the container, the latter being increased in diameter toward its top and extending above the upper edge of the tub, the tub being surrounded at its upper edge by an integral inwardly curved rim, a portion of which is enlarged and disposed below this edge of the tub, serving to collect water thrown from the container, and a driving shaft extending upwardly through the first named tubular partand connected to the remaining tubular part to impart rotation to said container.

3. A washing machine comprising a stationary tub provided at its center with a tubular upwardly extending portion which is open at its top, a clothes container in the tub, being provided at its center with a perforated upwardly extending portion spaced from and surrounding the first named tubular portion .and being closed at its upper end, a driving shaft extending downwardly through the first named tubular portion, means connected with the lower end of the shaft for imparting rotation thereto, a cover for the container resting on the closed upper end of the second named tubular portion and on the upper edge of the container, and a retaining screw extending through the cover and closed end of the second mentioned tubular portion, and having screw threaded engagement with the upper end of said shaft, serving to retain the cover in position.

In testimony whereof I have hereunto set my hand.

HECTOR RABEZZANA.
