• US Patent No.3044089 discloses a golf ball washing machine in which a reciprocatory and part rotary motion is applied to the unit to facilitate the cleaning of the golf ball.
• These patent specifications for material treatment or washing apparatus are either operated manually, or have mechanical gearing such as cams, screw threads or the like, or crank action mechanisms to apply the desired motion to the washing or cleaning apparatus.
• an apparatus for material treatment, washing and the like comprising a bowl or container, means being provided to impart to the bowl or container an oscillatory vertical motion, and resilient means suspending bowl or container such that the oscillatory motion is converted into a part rotary motion by the suspension means.
• FIG.l discloses a perspective view of one form of the invention which is suitable for washing small units, such as a washing machine of toy form for washing dolls clothes.
• FIG.2 shows an alternative form of washing machine in schematic form
• FIG.3 shows a plan view of Figure 2
• FIG.4 shows an alternative form of washing machine having means for extraction of the water from the bowl of the washing machine. DESCRIPTION OF PREFERRED EMBODIMENT:
• 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 rotational sense so that the bowl partakes of a combined vertical and rotational movement.
• 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.
• the electromagnet can be double acting to assist the resilient straps in returning the bowl to its original position.
• the straps are of a resilient plastics material, or alternatively for larger units spring steel or stainless steel straps can be used.
• 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.
• the base 3 could also be circular or could be of rectangular shape with suitable controls for the operation of the washing machine.
• the valves operating the electro- magnet could be provided by battery or batteries incorporated within 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.
• 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.
• 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.
• 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.
• this can include an air 5 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.
• the moving iron core 6 of the electromagnet 10 4 can extend through the electromagnet 4 to actuate the bellows or diaphragm pump 9 with the pump either continuousl 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
• 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.
• the pump while being an air pump can also pump 25 and discharge the water or other liquid either to waste or to be recycled if desired.
• 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 5 moisture would be removed due to this lower pressure.
• the lid can be removed for the drying T _ 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 ⁇ _5 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.
• the straps 2 extend upwardly from the supporting ring 8 and are attached to a further ring 9 attached to the supporting framework 20 10 of the washing machine, so that the bowl is suspended from the further ring 9.
• 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.
• 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.
• 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, grinding and milling, for example by the use of abrasive grinding balls or the like.
• 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.
