(Cl. ca -196) This invention relates to combined clothes washing and-rinsing machines and has for its general object to provide means whereby a washing machine structure may be utilized in an economical and emcient manner forenabling the 5 clothes to berinsed therein and removedtherefrom afterthe conclusion of the washing operation. In my Patent No. 2,161,022, issued June 6, 1939, there are shown, described and claimed a means for enabling a washing machine of one type of standard construction to be utilized as a rinsing machine and wherein this result is accomplished by suspending a perforated cover within the top of the tub of a washing machine, wherein the cover is provided with acentral opening to permit the top of the rotor to extend therethrough, and the body of the tub is provided with an overow located above thesaid My invention herein has for one of its more 20 limited objects to provide the tub of a Washingmachine with rinsing means including a cover element having a perforated bottom portion and which cover element is removably applied to the top of the tub and wherein the perforated portion of the bottom is provided with means for effectively handling and of the soapy water contained in the clothing after the preceding washing operation.

A further object of my invention is to provide a cover element of this type with means whereby substantially all of the liquid which may be passed through the perforations of the bottom portion of the same may be .quickly and coning operation. I accomplish the foregoing .objects in and throughthe construction and arrangement of parts shown in the appended drawing,wherein Fig. l represents a central vertical section portion of a washlngmachine embodying my invention; the. rotor being shown in elevation; and Fig. 2 a detail in section taken ontheline2-2 ofFig.1. fj V l I Describing the construction and arrangement 45 of parts shown in the said drawing, I denotes the of standard construcbottom 2 on a support- `tion, the same having aA ing base 3, and provided at its top with an' open outwardly concave around. l l

and as such tion of the lsame are unnecessary thetub, the same being Iprovided with a valve 8. The construction and arrangement of all of the foregoing parts are those employed in a well known type of washing machine and need .no further description.

In orderl to convert the machine thus shown and described into-an effective rinsing machine, I have provided the following construction: 9 denotes a cover element, the same having a top wall III, a perforated bottom wall Il. and a side wall I2. Extending from. said cover element above the bottom thereof is a wide outwardly and. downwardly extending discharge spout I3, the same having its delivery outlet Il located below the top of the tub and below the perforated bottom II.V Adjacent to its lower end, the cover element is provided with a. flange I5 providing. with the portion of the side therebelow a downhaving a gasketvi seat is extended downwardly below the bottom II to provide an annular rim I1 which fits within the bead 4. j

The cover element may be secured in place by means of ahook I8 located beneath the central and by one or more hooks adapted to be swung into engagement with the outer downwardly and outwardly-extending edge of the bead 4, each of said hooks being adapted to be operated by a lever shown as oomprising side members lower ends of the side members are .mounted upon a` shaft 2l extending through lugs 22 projecting upwardly from the channel iiange I5 and the upper ends of the said side members are connected by a pin 23 mounted therein with the "upper end of the hook 24 the lower end of which to be swung beneath-and engage the end of the bead I when the lever is shown in Fig. 1. Asstated, more than one of these locking membersV II-2I may be' provided for the cover element, if desired. Inaddition, the cover element is provided with handles 25 to permit its application to or removal l tub. The bottom I I of the cover element is a plate provided with upwardly tapered openings 26 and with radial ribs 21 and concentric circular ribs 28, the rim I1 constituting the outermostlof the said concentric ribs.

is `adapted outturned moved tothe position means .in their details form no part of my invention herein, illustration and descrip-1 I9 and a handle 20. The

Adjacent to the spout I3, the bottom is depressed to form a sump 29, preferably oval in outline, with its longer axis transverse of the axis of the spout. 'I'he said sump is provided with upwardly tapering openings 3U in the extreme bottom thereof and with upwardly and inwardly tapering openings 3l extending entirely about and through the wall of the sump intermediate the bottom and the top thereof. Between the series of openings 30 and 3I, the downwardly and outwardly extending ribs 32 are located.

The bottom of the sump thus described cooperates with the remainder of the bottom of the cover element in providing for the delivery of rinsing water therethrough, while the ribs on the sump as well as those on the remainder of the cover element prevent the articles being rinsed from being forced into engagement with the portion of the bottom intermediate said ribs and from clogging the openings therethrough. In addition, and at the conclusion of the rising op-4 eration, the sump provides part of the means for effecting speedy removal of any water which may tend to remain below the bottom of the receiving end of the spout, both above the bottom of the cover element and within the top of the tub to the level ofthe bottom of the tube within the sump. Cooperating with the sump is a Siphon tube 33 having its inner end in close proximity to the depressed central portion of the sump and extending through and below the spout I3 and having its lower end located a distance below the said sump and provided with a valve 34. 'I'he provision of the two series of openings 30 and 3I in the sump is for the purpose of securing an ample supply of liquid to the sump at all times until the lower end of the siphon tube is unsealed. With the parts constructed and arranged as y describedfthe operation will be readily understood. The water for washing the clothes or other articles may be placed in the tub in the usual manner, orsupplied through the drain connection 1 by slippingover the end .thereof a hose 35 having at its opposite end a faucet 36. After the tub has been filled, for washing purposes and soap added thereto, the rotor 5 will be operated to agitate the articles in the soapy water in the tub. The clothing may then be removed and one or more new batches added and washed with' the same water.

At the end of the washing operation, the soapy water will be withdrawn through the drain connection. The clothing which has been washed will be wrung to remove excess dirt and soapy water therefrom, after which the batches will be put into the tub and each batch treated as follows: The cover element 9 will be applied to the top of the tub by rst engaging the hookfl`84 beneath thebead I, as'shown, and thereafter moving the cover downwardly to its seat upon the top of the said bead and by locking the operating lever (or levers) I9, 20 in the manner described to lock the other portion of the cover element in place. Water'for rinsing purposes may then be supplied tothe tub while the rotor is operating. This will enable the water to pass in contact with and through the batch of clothing to be rinsed as the latter are being agitated bythe rotor and the soap or any sediment which may still remain in these articles will be completely removed therefrom, the water containing the soap and sediment being delivered through the waste pipe I3. The shape of the

openings

23, 30 and 3l enables the soap to be collected about the edges thereof and the combination of the radial and circular ribs provides traps for the soapy water which prevents the latter from sloshing around and retarding the rapid delivery of the soapy water from the articles and from thetub.

At the conclusion of the rinsing operation, the valve 36 will be closed and the valve 34 opened, and any water that may be within the machine above the perforated bottom and also below the said bottom to the level of the bottom of the inner end of the siphon tube will be withdrawn through the latter. This will enable the operator to disengage the cover element from the tub and remove the cover without liability of spilling water upon herself; also, because the water will have been withdrawn below the top of the tub by the action of the siphon tube, the operator will be enabled to remove the clothing from the tub without liability of spilling water over the top of the latter and upon herself. The ribs 32 which substantially surround the openings 30 and 3| prevent these openings from being clogged by the articles of clothing in the upper portion of the tub.

Having thus described my invention, what I claim is:

l. A removable cover element for the tub of a machine of the character described, the said cover element having a side wall and a perforated bottom wall below-the top of said side wall, the said cover being provided with a discharge outlet communicating with the space above said bottom wall, the said bottom wall having a sump extending therebelow and adapted to communicate with the space thereabove and provided with one or more openings communicating with the` space therebelow, and a siphon tube having an upper receiving end located within said sump below the portion of the bottom wall thereabove and extending through'the side wall'of the cover and having its lower delivery end located below its inner receiving end and provided with a valve.

2 The cover element recited in claim 1, wherein the said openings in the sump are provided with downwardly extending ribs adjacent to the said openings.

3. The cover element recited in claim 1, wherein the said discharge outlet is anv outwardly and downwardly extending discharge spout, and wherein the said siphon tube extends through the saidspout and has its delivery end located therebelow.
