  In addition, the lid is recessed remote from the hinge 23 to provide a handle or grip 24 which can be readily grasped by the operator to swing the lid into or out of its closed position. In this instance, the top panel is apertured adjacent a front corner thereof, which aperture has a control shaft 25 extending upwardly therethrough with a control knob 26 mounted thereon adapted to be grasped by the operator for manipulation. One of the control shafts is adapted to be adjusted for controlling a thermostatically operated mixing valve 21, and the other is adapted to be manipulated by the operator for manually positioning a plurality of cams 28 normally driven by a timer motor 29 through any suitable speed reduction mechanism for automatically controlling the washing cycle, as diagrammatically shown in Figure 6 of the drawings.
  
  The outer stationary tub may be supported, in any suitable manner, by a plurality of corner posts 36 and is preferably formed circular in horizontal cross section, with an upper open end 32 disposed adjacent the lower portion of the top panel l6 and a lower bottom portion 34 having a, drain opening 36 and a centrally disposed enlarged opening 38 in a centrally located crowned portion 39 through which vertical coaxial shaft means extend. The shaft means is in the form of an inner rotatable shaft 46 and an outer rotatable tubular shaft 42, for supporting and rotating the inner tub 8 and for actuating the agitator l0.
  
  Disposed within and at the upper portion of the outer stationary tub 6 and secured to the upper end of the outer tubular shaft 42 is the inner rotatable tub 8, also preferably circular in horizontal cross-section and in this modification it is formed in two sections or parts 43 and 44. The outer part or receptacle 43 is substantially cup-shaped in vertical cross-section with its open end facing in the direction of the cover and has an imperforate cylindrical side wall 45 having a major portion thereof tapering slightly toward the open end which terminates in a top edge 46 adapted to extend above the normal liquid level desired for washing. The lower portion of the side wall 45 is tapered slightly at 41 toward a generally horizontal bottom wall 48 formed with a centrally disposed hub 49 and is spaced therefrom by means of a plurality of spaced inwardly and downwardly projecting lugs 56 formed integral with the lower portion of the side wall to define an annular circumferential passage therebetween. This passage is sealed against liquid flow when the tub 8 is stationary by means of an annular resilient centrifugally operated valve member 52 in a manner to be hereinafter described.
