WASHING AND nmsme moms ton ; Robertson, Cape Hamil Barry Province, Union of South Africa Application the Union of 2 Claims. (Cl. 210-75) This invention relates to improvements in combined washing and rinsing machines of the type in which the soiled washing -is'conta-ined in a perforated container or spinner basket which is adapted to rotate or spin inside a circular tank or tub in which the hot soapy washing-water is also contained. The arrangement is such that during the washing operation, the spinner basket is adapted to rotate in a position in which its axis is horizontal so that it is partly submerged in the hot soapy washing water in the lower portion of the tank. During the rinsing and drying operation the spinner basket is turned into a position where it rotates about a vertical axis so as to be elevated above the washing water level.

During this rinsing operation the rinsing water, usually cold, is introduced while the spinner basket is rotating and by centrifugal action this water is carried through the articles being washed, from which it carries the particles of soap and dirt. Thereafter, on passing through the perforations in the periphery of the spinner basket, it is flung against the inside surfaces of .the walls of the tank, whence it trickles down to join the washing water in the lower part of the washer. Where successive washes are to be un dertaken with the same washing water, it is undesirable to have the rinsing water diluting and/or cooling the washing water.

Objects of the invention are to provide means for overcoming these disadvantages of dilution and cooling during the rinsing operation, while at the same time providing means whereby, during the washing operation, the soapy water may be returned to the lower part of the washer for reuse.

According to the present invention an annular gutter or trough is secured to the inside of the tank or outer casing in a position above the nor- .mal washing water level, so that the rinsing water, gravitating down the inside of the tank, is collected in the said gutter, the gutter bein provided at its lowest point with a discharge outlet through which the rinsing water is discharged to waste or to an automatic discharge pump by means of which the water is removed from the washer.

In a preferred construction the discharge outlet, connecting the gutter and the waste outlet, is provided with a closure in the form of a plug, operable from the outside of the tank, whereby during washing operations, the hot soapy washing water collecting in the gutter will be diverted back to the washing water, while during rinsing operations the plug will cause discharge .of the water from the gutter to waste or to the discharge pump. The operation of the plug may be effected manually but may also be effected automatically by interconnection with the spinner basket so that when the basket is turned to either of its operating positions the plug is simultaneously changed to its corresponding position.

In the preferred construction the plug referred to is interconnected with a hollow drain plug forming a closure for the waste outlet, in such a manner that a single control member in its lowest position causes both openings to be closed, in an intermediate position it causes the gutter discharge outlet only to be opened, and in its.high est position, causes said hollow drain plug to be opened for emptying purposes.

To enable the invention to be more clearly understood and carrled'into practice, reference is now made to the accompanying drawings in which like reference numerals denote like parts throughout the several views.

In the drawings: r

Fig. 1 is a' perspective view, partly cut away, of a washing machine of the type described and embodying the invention.

Fig. 2 is an enlarged perspective view of portion of the gutter.

Fig. 3 is a side elevation of the closure means shown in relation to the gutter and the tank.

Fig. 4 is a vertical section taken on line IV-IV of Fig. 3, showing lowest position of closure means.

Fig. 5 is a similar view to Fig. 4 but showing intermediate position of closure means, and

Fig. 6 is a similar view to Fig. 4 but showing the highest position of the closure means.

Referring to the drawings, reference I denotes the tank or tube of .a washing machine of the type referred to, within which a perforated spinner basket 2 is mounted for rotation about both a horizontal and a vertical axis. The spinner basket 2 is shown positioned for rotation about a vertical axis, the necessary power for-which is obtained from an electric motor 3 which likewise drives an ejector pump 4 connected to a waste outlet 5.

An annular gutter 6 is shown'flxed to the interior surface of the walls of the tank I at a position slightly above the normal level of the washing water. When" therefore, during the rinsing operation, the spinner basket isrotated in the position shown, the water is flung outwardly by centrifugal action on to the inside walls of the tank and, on trickling downwardly, is caught by the gutter 8, whence it is discharged byway of the waste outlet without causing dilution or cooling of the washing water in the lower part of the tank I.

a When the spinner basket 2 is being rotated about a horizontal axis, during the washing operation, the soapy water which then collects in the gutter 6 will be required to be returned to the body of washing water in the lower portion of the tank I. To achieve this result, closure means .are provided for the discharge outlet from the gutter 6, whereby such water may be caused to return at will for reuse by passing over the weir portion 1 of the gutter 6. The closure means will now be described with reference to Figs. 3 to 6.

. The closure-for the waste outlet 5 consists of a tubular drain plug 8 provided with a sealing ring 9 of rubber or the like on its lower end, while its top open end is adapted to be closed by the solid plug ID. The hollow drain plug 8 is slidably located in a sleeve ll projecting downwardly from an opening in the bottom of the gutter 6. To prevent leakage, a rubber sealing ring l2, of circular cross section, is interposed between the hollow drain plug 8 and said sleeve H, with which surfaces it is adapted to make continuous rolling contact when relative sliding movement takes place therebetween. To prevent displacement said sealing ring I2'is located in an annular recess I3 formed by a reduced portion of the hollow drain plug 8.

The plug Ill is interconnected with the hollow drain plug 8 by a lost motion device consisting of a rod l4, slidably movable in a hole in a cross bar l5 fixed inside the hollow drain plug 8, and a. compression spring l6 threaded over said rod l4 and tending to press the plug l0 upwardly and away from the hollow drain plug 8. The rod l4 after passing centrally through the plug Ill, is connected to a slidably mounted handoperated lever H, the top end of which is conveniently accessible by terminating adjacent the top edge of the tank l. The lever H has three positions defined by the depressions ornotches l8 whichare adapted to co-actwith the springpressed locating stop it. A strainer 20 surrounds the lower end of the hollow drain plug 8.

During the washing operation, when it is desired to return the water collected in the gutter 6 to the main body of water, the'several parts are in the positions shown in Figs. 3 and 4, whereby the top open end of the hollow drain plug 8 is closed. This causes the collected water to flow over the weir I back into the lower part of the tank 8.

During 'the rinsing operation, when it is -desired to permit the rinsing water to flow to waste so as notto dilute and/or cool the washing water, the lever-this raised to the intermediate notch as shown by- Fig. 5. This action raises the plug 10 but, due, to the lost motion connection, it does not open thehollow drain plug 8. The collected vided with a waste outlet in the bottom thereof..-

way of the waste outlet 5. When it is desired to empty the tank I, the lever i1 is moved to the position shown by Fig. 6. This movement causes the enlarged end 2| of the rod M to contact with the crossbar li and thereby to raise the hollow drain plug Belfbbdily so as to open the waste outlet 5.
