Patented Oct. 10, 1939 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates to improvements in washing machines, and the object of the invention is to devise a simple, eilicient machine which will provide for a continuous and thorough circulation of the water through the clothes and which will produce such circulation at lower speeds of rotation. The invention consists essentially of an outer stationary cylinder .water container, an inner perforated revolving cylindrical clothes container spaced from the walls of the water container, a curved annular lip carried by the upper edge of the water container and curving inwardly over the upper edge of the clothes container, stationary vanes secured to the water container and extending spirally between the water and clothes containers, and vanes carried by the clothes container and extending spirally from the exterior thereof in an opposite direction to the aforesaid stationary va nes whereby the water between the water and clothes containers is lifted and carried upward onto the stationary vanes to be directed over the upper edgeof the clothes container and in a shower onto the clothes to return to the outside of the clothes container through the perforations thereof.

Fig. 1 is a. perspective views of my washing machine broken away to exhibit the interior structure thereof.

Fig. 2 is a vertical sectional view through my machine.

Fig. 3 is a plan view of my machine, the left side being in plan elevation and the right side with the annular lip of the water container broken away and in section.

Fig. 4 is a perspective detail of one of the water directing vanes.

Fig. 5 is a side elevation of a modified construction.

In the drawings like letters of reference indicate corresponding parts in the different views.

The numeral I indicates a water container mounted on a stand 2. water container wall is provided with -an annular edge groove IX in which fits the curved annular lip 4 preferably secured in the groove by a bayonet slot and pin 5 and 6.

1 is the driving shaft mounted in a bearing sleeve 8 extending through a circular opening 9 formed in the centre of the water container I and provided with a flange I0 formed integral therewith and bearing against the inner face of the bottom wall of the water container. II is a nut which is screwed onto the,lower end of the sleeve 8 against the lower face of the bottom of the water container so that such bottom is The upper edge of the clamped between the ange I0 and nut IIv to form a water tight joint.

A clothes container I2 located centrally within the water container I is provided with walls having perforations I2X to allow `of the passage of the 5 Water between the containers I2 and I. The Wals of the container I2 are spaced from the walls of the container I so as to allow of an intervening body of water. The bottom of the clothes container I2 is provided with a central orifice I3.

I4 is an outer bea-ring sleeve fitting around the inner sleeve 8 so as to revolve freely thereon and is provided, at its lower end, with an annular flange I5 secured to the clothes container bottomto form a water tight joint. A cap I6 is secured 15 Within the sleeve I4 and to the shaft I so that the shaft l, sleeve I4, and clothes container I2 revolve in unison around the sleeve 8. A thrust bearing I1 is interposed between the cap I6 and sleeve 8, the sleeve 8 being provided with bushings 20 I8 and I9 within which the shaftv 1 revolves.

Spiral flanges 20 extend from and are formed integral with the clothes container I2 which revolves in the direction of arrow (see Fig. 1) so as to lift the water between the containers I2 and I which is then picked up by the stationary spiral blade members 2I which are secured to the lip 4 by the tap screws 22 and extend between the walls of the containers I2 and I. The upper rim of the container I2 is provided with an annular inwardly extending flange 23 and the upper end of each member 2I with an inwardly extending radial portion 24. 25 are vertical ribs or flanges secured to the interior of the stationary water container I.

As the clothes container I2 revolves, the water exterior thereto and held stationary from revolving with the blades 20 by the ribs 25 is lifted vertically to a point above the ribs 25 and above the lower ends of the blades 2I above which point it is carried around the container I2 to travel up the blades 2| to be directed inward by the inward extensions 24 over the flanges 23 to fall in a shower onto the clothes within the container to be then directed by centrifugal action outward through the clothes and perforations I2 to the exterior of the container I2 to be again circulated upward and over the rim of the clothes container.

By disengaging the lip '4 by means of the bayonet slot and pin connections 5 and 6, the 50 clothes container I2 may be lifted out so that its exterior and the interior of the water container I maybe easily cleansed.

In Fig. 5 I have shown a modified form in which the stationary blades 26 carried by the 55 water container 21 cross or intersect the movable blades 28 carried by the clothes container 29.

By the arrangement of blades 20 and 2|, the water is circulated without the clothes container being rotated at high speed. 'I'he clothes container being rotated at lower speed, the clothes are not forced outward with great pressure against the` perforated wall of the container so as to prevent the free circulation of water through the perforations.

What I claim as my invention is:

l. A washing machine comprising an outer stationary water container, an inner perforated clothes container revolvably mounted within the outer container to form an annular water space between the containers, exterior spirally bent vanes extending from the clothes container, interior spirally bent stationary vanes carried by the water container and set in an opposite direction to the vanesof the clothes container whereby the lifted water is carried over the upper edge oi the clothes container onto the clothes contained therein, and means for preventing the rotation of the water between the clothes and water containers bythe rotation of the clothes container as the water is lifted by the vanes of the clothes container.

2. In a washing machine, a stationary outer water container, an inner clothes container vmounted to revolve in the outer container, forwardly facing spiral vanes extending from the outer periphery o! the clothes container and from the bottom of the container to a point intermediately of its height, and rearwardly facing curved stationary vanes carried by the water container extending between the walls of the clothes container and the water container and from above the clothes container rim to a point closely adjacent to the path of travel of the upper ends of the spiral vanes.

3. In a washing machine, a stationary outer water container having a central orifice in its bottom wall, an inner container having perforations in the wall thereof and having a ntral orice in the bottom wall in line with the aforesaid oriflce, a sleeve secured to the bottom wall and extending upwardly from the central orifice of the inner container to above the water level, a sleeve secured to the bottom of the outer container and fitting the sleeve of the inner container, a cap for the upper end of the outer sleeve, a step bearing between the cap and inner sleeve, an annular member having a convexed inner face carried by the rim of the outer container to overhang the same, means for detachably connecting the annular member to the rim, and spiral blade members secured to the annular member and depending into the interspace between the inner and outer containers.
