Referring now more in detail to the drawing for one form of a combined washing and drying machine, embodying a rotatable tub of double wall construction made in accordance with the present invention, there is shown an outer cabinet 2, secured to a base structure Il having adjustable leg portions 5 for completely enclosing the operating parts of the machine. The base 4 provides a support for an outer stationary tub 6,ore crusher a support for an inner rotatable tub 8, which is mounted for rotation about a vertical axis, having an agitator or washing device m disposed therein,y as well as a support for mechanism, generally referred to as I2, for operating the agitator It and rotating the tub 8 in a washing cycle, as will be hereinafter ...view middle of the document...
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 and out of its closed position. vIn this instance, the top panel is further formed with two openings adjacent the front corners thereof, each of which has a control shaft 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 2l, and the other is adapted to be manipulated vby the operator for .manually positioning a plurality of cams 23 normally driven by a timer motor 29 through any suitable speed reduction mechanism for automatically controlling the washing cycle, as diagrammatically shown in Figure 4 of the drawings.
The outer stationary tub may be supported, in any suitable manner, by a plurality of corner posts 3i] and is preferably formed circular in horizontal cross section, with an upper open end disposed adjacent the lower portion :of the top panel I6 and a lower bottom wall 34 having a drain opening 36 and a centrally disposed -enlarged opening 38 in acentrally located crowned 'portion 3B through which vvertical 'coaxial shaft means extend. The shaft means is in the Aform of an inne-r rotatable shaft 4t and an outer rotatable shaft 42, for supporting and rotating the inner tub 8 and for actuating the 'agitator 1B.
