wAsH MACHINE Filed March 25. 1941 A INVENTOR. Era/v6.44 a/WMM Patented Feb. 16, 1943 UNITED STATES PATENT OFFICE 2,310,950 Y wAsn Maenner:
Bronislaw Goldman, Canton, Ohio Application March 25, 1941, Serial No. 385,125
3 Claims. (Cl. 68-27) My improvements refer to a wash machine 'of the type which is commonly employed for h'ousehold uses and in which the washing process is performed by setting the liquid in which the washing is-performed into motion by means of a motor-driven agitator. The purpose of my invention is to provide an agitator of a very simple construction and yetcapable of high degree of efficiency.
Another and very important purpose of my invention is to provide means within my wash machine for the purpose of removing moisture from the objects which had been washed therein. What my invention contemplates is amachine of the type which not only is capable of performing the Washing operation but which also can be used for the purpose of drying the 4objects which had been washed and this without the use of any complicated devices or any extra containers. As a matter of fact, as will be later shown, the machine of my invention can perform both functions at the same time. It can be applied to perform the washing operation, while at the same time, by means of the same shaft which drives the agitator for washing purposes and within theI confines of the receptacle in which the washing is done, another member of the machine may be utilized for the purpose of drying out the objects which had been washed before.
Another purpose of my invention is to effect an economy of the washing liquid by combining the washing and the drying means of my machine in the same receptacle so that the liquid driven out by the drying means may be utilized for washing purposes.
Another purpose of my invention is to secure the liquid available from the drying operation for washing purposes without the use of any pumps or other special mechanism.
Having thus indicated in general the purposes for which my improvements have been devised, I shall now describe them with reference to the accompanying drawing, in which:
Fig. l shows a vertical sectional view of my machine.
Fig. 2 shows a horizontal sectional view of my machine taken on line 2-2.
Fig. 3 shows a perspective view of the drying element of my machine.
Fig. 4 shows a fragmentary sectional view of another form of my machine.
Similar numerals refer to throughout the several views.
The wash machine of my invention comprises a receptacle I0, closed at the bottom and open similar parts Cil at the top, but provided with a. removable cover II in which I2 indicates a handle. The receptacle may be in the form of a drum, although the shape is not critical, and a rectangular or some other form may as well be used. The drum is mounted on a platform I3, supported on a stand I4. A motor l5 is attached to the underside of the platform I3 by means of bolts I6.y
The shaft il of the motor I5 extends through the center of the platform I3 into the interior of the drum I0, where it is axially disposed with reference thereto. The shaft, in its upper part, within the drum, may be either flattened on one side or square in cross-section. A packing i8 is provided around the shaft right under the bottom of drum I0 where said shaft enters said drum. A cylindrical drum I9 having a socket tom 26 of drum 24. The drum 24 is of a diameter somewhat larger than that of the agitator. It is open at the top and provided with aplurality of perforations 425 in its wall.
A number of fin-like battles 21 project from the interior wall of my receptacle I0, to serve a purpose which will be later described. The upper edge of the fins extends to a point somewhat above the level of the bottom of drum 24.
The washer shown in Fig. e is substantially the same as that shown in Fig. 2. In this case the receptacle is indicated by numeral 28; the perforated dryer by numeral 29; the agitator by numeral lSill. It Will be seen that the agitator is also provided with perforations 3l. These perforations serve to enhance the efficiency of the agitator in setting the liquid within the receptacle into a rotary motion. The proportion between the size of the receptacle and the size of the agitator and the dryer within is somewhat difterent than that shown in Fig. 1, but this is obviously optional, if the diameter of the dryer provides sumcient room for removal of the clothes through the space between the dryer and the receptacle wall. Likewise, the diameter of the agitator drum is optional if its periphery is sufficiently large to prevent tangling ot the clothes in the receptacle.
As I have indicated in the beginning, the purpose of my machine is not only to perform washing, but also to serve as a centrifugal dryer. Ordinarily when washing is to be done, the receptacle is to be filled with liquid which should reach to a point below the level of the top of the agitator. 'Ihis naturally is not a critical requirement, although preferable for best results. Then the motor is started and a rotary motion is departed to the agitator I9. Even if the wall should be entirely smooth, although it need not be, the liquid within the receptacle would be set into a rotary motion by reason of adhesion ofthe liquid to the surface of said agitator I9. This istrue particularly if the motor is made to rotate rapidly. Since a degree of turbulence and commotion of this liquid is desirable, this is secured by means of bafiies 21. When washing is being thus performed, the drum 24 rotates together with the agitator and the only service that it may perform is that the liquid thrown against the bailles and rebounding from the interior Wall ofV receptacle I against said drum is stoppedl by theexternal surface of the drum and made to drop back into the receptacle. But While the washing is being performed in the lower part of the receptacle I 0, drum 24, which is rapidly rotated bythe agitator, may be utilized as a conventional centrifugal drier. 'I'he rotary motion of the drier causes liquid absorbed in washing by the objects placed in the drier to be thrown out through perforations 25. Said liquid would, by gravity, find its Way to the lower part ofthe receptacle where itcan contribute to the quantity of the liquid contained therein.
Although the lower part of the agitator is capable of performing its function separately and independently of the upper part, and although the upper part, that is the drum, may be used separately without reference to the function of the agitator, it will be seen that both said elements, that is, the agitator and the drum, act in combination, as the shaft which operates the agitator also operates the drum, thus eliminating the necessity of a separate container for the drier, also because the liquid which is thrown out by the drier 24 flows back into the lower part of the receptacle where it performs a useful function in conjunction with the agitator.
To sum up, the improvement shown by me eliminates the necessity of a separate'drier and makes it possible to carry on simultaneously what otherwise would be successive stages oi' the spirit of my invention, I wish to present thel following claims:
1. In a washing machine, a tub for clothing and washing solution having radial projections on the inner wall thereof, a rotor mounted centrally and extending substantially the full vertical height of the tub having a cylindrical bottom portion of substantial diameter for subjecting the washing liquid and clothes to circular movement against the resistance of the radial projections of the receptacle, and said rotor having a perforated upper portion constituting a centrifugal dryer receptacle of a diameter suiliciently less than the wall of the tub to allow for the removal of the clothes through the annular space therebetween, a cover for said tub, and drive means for the rotor.
2. In a washing machine. a tub for clothing and washing solution, a rotor mounted centrally and extending -substantially the full vertical height of the tub having a cylindrical bottom portion of substantial diameter for subjecting the washing liquid and clothes to circular movement, and said rotor having a perforated upper portion constituting a centrifugal dryer receptacle of a diameter sufficiently less than the wall of the tub to allow for the removal of the clothes through the annular space therebetween, a cover for said tub, and drive means for the rotor.
3. In a washing machine, a tub for clothing and washing solution, a cover therefor, a rotor mounted centrally and extending substantially the full vertical height of the tub having a cylindrical bottom portion of substantial diameter and of a length corresponding to the height to which the tub will be filled with clothing and solution, said portion being in such proximity to the base of the tub that no clothing can pass between the base of the rotor and the tub, said rotor being provided with a perforated receptacle of cylindrical form extending above the water level of the tub, which is of a diameter to provide an annular space between the receptacle and the tub of a sufficient width to permit the free handling of the clothing in removing the same from the tub to the receptacle, and drive mechanism for said rotor.
