DESCRIPTION Ox PREFERRED EMBODIMENT:
As shown in Figure 1 the bowl 1 is supported by resilient straps 2 supporting base 3, the straps being for example three or four in number and positioned around the bowl or container to extend downwardly and being inclined to the vertical, and inclined across the axis of the bowl in what may be termed the same direction of rotation, so that as the bowl is given an oscillatory vertical movement the bowl will also have an oscillatory motion in a rot-ational sense so that the bowl partakes of a combined vertical and rotational movement.
In order to cause the bowl 1 to have a vertical component of motion, an electromagnet 4 (as shown in Figure 2) can be positioned at the bottom of the,bowl, the magnetic coil 5 being attached for example to the supporting base or the like, while the metallic core 6 is attached to the bowl.
The action of the electro-magnet for smaller units can be in one direction only, and this would be against the action of the resilient straps so that when the electro-magnet is disengaged the straps will return the bowl or the like to its original position.
In larger installations the electromagnet can be double acting to assist the resilient straps in returning the bowl to its original position. Preferably the straps are of a resilient plastîcs material, or alternatively for larger units spring steel or stainless steel straps can be used.

As shown in Figure 1 the springs or straps 2 are preferably attached to shaped brackets 7 attached to the base, and at their upper ends are either attached directly to the bowl, or to a support strap or ring 8 encircling the bowl 1.
While the bowl is preferably cylindrical, the base 3 eould also be circular or could be of rectangular shape with suitable controls for the operation of the washing machine. In Figure 1 the valves operating the electro-ln magnet could be provided by battery or batteries incorporatedwithin the base, suitable controls and switching such as IC switching units being incorporated in the base 3.
The angle of the inclination of the springs to the base could be any desired angle, and ideally the strength of the springs would be chosen such that when the bowl is loaded with clothes and water, the springs would deflect slightly but still give the required movement.
As shown in Figure 1, the straps are attached to the ring encircling the bowl at or above the centre of the bowl, it being desired that the ring and attachment of the straps be positioned above the centre of gravity of the bowl when the desired quantity of liquid and clothes are inserted within the bowl.
As shown in Figure 2 the ring 8 is positioned at the top of the bowl with the straps being extended in length and extending around the bowl and then having a straight portion extending downwardly to the base.

As shown in Figure 4 the unit is disclosed as a washing machine also having means for removing the water from the bowl, and also for partial drying of the clothes.
As shown in the drawings this can include an air or vacuum pump 9, and in a simple form can comprise a bellows or diaphragm type of pump. This can also be operated by the same electromagnet 4, or by a separate electromagnet and its control circuit can be provided.
In one form the moving iron core 6 of the electromagnet 4 can extend through the electromagnet 4 to actuate the bellows or diaphragm pump 9 with the pump either continuously operating, or by having a releasable catch mechanism to connect the moving iron core to the actuator for the pump. "
A flexible connection 10 can be provided by an opening in the bottom of the bowl to the inlet of the pump, and if desired depending upon the circumstances, a sieve or screen or the like can be provided within the bowl to prevent the goods or material from blocking the outlet from the bowl.
Valve means can be provided in the connection between the bowl and the pump to control the withdrawal of the water, or other medium in the bowl as desired.
Thus the pump while being an air pump can also pump and discharge the water or other liquid either to waste or to be recycled if desired.
., ~2;2~93 A lid 11 can be provided for the bowl to seal the bowl so that a reduced pressure would be created within the bowl to assist the drying of the clothes or other materials within the bowl, so that a certain amount of moisture would be removed due to this lower pressure.
The lower the pressure obtained 9 the more moisture would be transferred to the atmosphere within the bowl to be removed from the clothes or other materials in the bowl.
If desired~also the lid can be removed for the drying process so that air would flow through the clothes as they are being tumbled and agitated in the bowl, or alternatively the lid may have a small aperture to allow the regulated passage of air into the bowl through the clothes or other material and in a further,~alternative heated air may be supplied by a heater incorporated within the lid so that warm air would pass through the clothes for the drying thereof. As shown in Figure 4, the straps 2 extend upwardly from the supporting ring 8 and are attached to a further ring 9 attached to the supporting framework 10 of the washing machine, so that the bowl is suspended from the further ring 9.
It will be realised that according to the invention there is thus imparted to the bowl an oscillating and agitating movement and while it has been particularly described in relation to a clothes washing machine, the unit can be used in various other processes such as agitation,separation, screening and grading processes, floating processes, cleaning and washing, suspending, polishing, shaking and mixing, and also grinding and milling.
~;~2~ 3 8.
For this purpose the bowl or container can be provided with suitable sieves or screens with appropriate inlet and outlet connections being provided above and or below the screens as desired.
Thus within the bowl or container it will be realised that the bowl or container can be lined with any suitable material for the particular processes envisaged, for example stainless steel, ceramics or even rubber lined when a unit is to be used for the polishing, 8rinding and milling, for example by the use of abrasive grinding balls or the like.
Also this invention can be applied to domestic cooking apparatus, whereby the slow movement and oscillation of a cooking pot can be achieved, the ingredients such as soups and stews or the like can be kept in constant movement to prevent burning on the bottom, particularly when coming to the boiling stage.
In all the examples, it will be realised that the frequency and the stroke of the electromagnet can be varied as desired, this being easily achieved by suitable control circuits.
While an electromagnet has been described as the means for producing the vertical movement, it is to be realised that other forms of driving units could be provided, either pneumatic or hydraulic, or even mechanicalg whereby the resilient springs or straps would create the turning or oscillating movement for the bowl.
~Z 3 Also the movement could be created by other means such as if the unit were positioned in a moving vehicle such as a caravan, mobile home, boat or the like, the rocking and swaying movement of the vehicle would cause the bowl to partake of the agitating movement so that clothes could easily be washed while travelling to a destination and it is merely necessary then to remove the clothes for rinsing and drying.
