By having thew'ringer mounting at one side of the center'the cover knob is readily accessible and the cover may be easily lifted and taken out from the other side practically 'as readily, as though the wringer were not in place.

There is a great and rapidly growing held in 1 apartments, flats and single rooms; for small, compact washers which may be readily stored or rolled away into otherwise waste space and as easily rolled out again for use. A space-saving type where all space is at a premium. The present invention meets fully and quickly all such requirements, When not in use the wringer, comthe sink where it will have plenty of room and will occupy only space otherwise entirely waste. The wringer with drain board and handle discourse, only necessary. to turn out thescrews oi the drain board and loosen the set screw of the handle in order to disconnect them. And when the wringer is again desired it is only necessary to assemble the drain board and handle andagain set the wringer in place.

From the above it will be seen .-that gravity alone actuates the means for maintaining the wringer in operative position with'the feet 32 in the cooperating sockets 33 and the wringer upright above the tub but to one side of its center.

The construction, operation and use of the in-' vention will be clear from the preceding detailed description.

Having thusdescribed my invention, what I claim and desire to protect by Letters Patent is:

1. In combination,- a machine having a cylindrical upperwall, a wringer provided with vfeet spaced apart a distance less than'the outside diameter of said cylindrical wall and of the same curvature as said wall, a drain board carried by said wringer and normally extending outwardly relatively to the centre of the machine.

- and sockets carried by said wall constructed to s pport said feet in contact with said wall and removably support said wringer.

2. In combination, a washing having a cylindricalupper wall, a closure covering subi y the ire 1109. B, wrirmer across and above said wall and closure and prca vided with feet spaced apart a distance less than the outside diameter of said wall, said feet having inclined or tapered vertical'edges, a drain board carried by said wringer and normally extending outwardly relatively to the centre of the machine, said wall having sockets constructed to support said feet in contact with said wall and provided with walls of a taper corresponding to that of the aforesaid feet 'and-removably supporting said wringerin position.

3. In combination, a washing machine having a metal tub circular in cross section, a wringer having a pair of depending supporting feet spaced apart a distance less than the diameter of said tub, a pair of wringer supporting members carried by the side walls of said tub at one side of less than the diameter of said tub, a pair of wringer supporting members fixed to the side walls of said tub adjacent the top at one side of v the vertical axis of the tub and spaced from each other a distance corresponding to the distance between said feet, said members forming with the wall of the tub laterally diverging pockets, said feet formed with a corresponding divergenceto prevent an end-to-end reversal of the wringer with respect to the tub. 5.
