Application filed May 22,

My invention relates to improvements in washing machines.

1 ation of the driving mechanism. l

' An object of my invention is to provide in a washing machine having a vat in which is disposed a rotatable tub adapted to'serve as Y a washing tub. and a centrifugal drying tub, means whereby certain drainage of the tub may be collected in the vat for further use and other drainage of the tub may be discharged exterior of the vat, such discharge being in large part through the same channels.

vAn important object is the PIOVlSlOIIOf a suitable tub fort-he above purpose which when slowly rotatably oscillated carries without any substantial loss the water contained therein, yet when rapidly continue ously rotated throws. off the water from the contained clothes.

An important feature is the provision in i such a tub having discharge apertures of dially extending corrugations. The above ob ects and others, together with scription, accompanying drawings, and ap hoods formed on the inner surface of the tub, which hoods cover such discharge apertures, such tub being also preferably provided on its exterior surface with hoods .over the discharge apertures, which hoods open downwardly to direct the water passing through the apertures into a drainage collector surrounding the tub.

A novel part of the tub is the provision of an overhanging rim flange. A. plurality of spaced-apart upright fins extend inwardly from the flaring side wall of the tub and the bottom is provided with a plurality of raother important structural elements, will more fully appear from ,the following depended claims in which my invention is dcfined. i

My improved washing machine has a frame 10 suitablysupported by legs llwhich carries a vat 12 having a'depending skirt 13 and a removable cover 14. A motor 15 supported below the frame has a drive shaft 16 upon which is mounted a friction driving cone 17 which engages a friction disk-18 carried by a driven shaft 19 which shaft extends upwardly axially through the vat havinga bearing for support in a standard 20 of the frame 10. A protective shroud21 enclosesthe standard 20 and suitable packing 22 may be inserted between the shroud and the standard. .The shaft is provided at its upper end with splines 23 to engage a removable cone clutch 24 to rotate therewith. I provide a tub 25 which has a female cone clutch 26 provided with suitable recesses 26 to engage lugs 27 on the removable male clutch member24 so the tub when seated thereon will-rotate therewith. The remov' able clutclrmember 24 and the weight of the tub is carried on a bearing 28 which rests on the upper end of standard 20.

The tub is provided with an upwardly outwardly-flaring side wall 29 which has an overhanging rim flange 30, a crown-plate 31 being shown as extending over this rim flange The side wall of the tub is provided with a plurality of spaced-apart upright inwardly-extending fins 32 and the bottom of a the tub has a plurality of radial corrugations 33 and a drainage plug 34. The corrugations in the bottom of the tub andthe fins on the side-wall facilitate the washing; operation.

The tub is supported upon the removable clutch member 24 as is shown in Figs. 1 and 6, and is secured thereto by a removable plu 48 which is threaded into the enlarged en the member 26. A. spring 49 is held under compression against the end of shaft 19 by this plug 48.

As describedin my co pending application.

portion of the axial passageway through the tub is adapted to be slowly rotatably oscillated or rapidly continuously rotated.

During the slow rotatable oscillatory movement the clothes are washed. During the movement of rapid continuous rotation the water is expelled from the clothes.

In order that the tub may serve both purposes I provide in the upper portion of its side wall inproximity the overhanging flange 30'a plurality of apertures 34. These apertures are arranged at intervals around the wall of the tub. Over each aperture or group of apertures I provide interior the tub a hood 35 which extends between the side wall of the tub and the overhanging flange. This hood extends circumferentially the tub and is open only at one end. On the Outside of the tubv I provide a hood 36 which extends over the apertures 34.and is open at the bottom to direct the discharge through the apertures downwardly.

There is provided an annular drainage collector 37 in the form of a flange carried by the side wall of the vat'and surrounding the tub below the discharge apertures therein.

This drainage collector is adapted to; collect the drainage from the tub. It has an outlet pipe 38 which has a branch 39 that leads to an overflow bowl 40 and a branch 41 extending through the wall of the vat to discharge exterior thereof. A manually operable gate 42 is provided to regulate the flow of the water. When this gate is closed the water from the outlet pipe will enter the bowl and overflow into the vat.

' the water will discharge exterior the vat.

-This overflow bowl is so situated with revceptacle exterior the tub.

At the completion of a washing operation the tub may be rapidly rotated and the suds discharged into the collector 37 and drained into the bottom of the "at overflowing from the bowl 40, which will result if the gate 42 is closed, or the plug 34 may be removed and I the suds Water drained directly into the vat.

discharged through the apertures 34 into thecollector 37. The, gate 42 is now open and The clothes are permitted to remain in the tub and rinsing water is placed in the tub, after which the tub is rapidly continuously rotated to rinse the clothes and the water this rinsing water discharges exterior the vat. The overflow bowl is at such a height When the gate is open.

and the size of the discharge spout is sech that this result will occur. The clothes are now removed from the tub and a second washing of clothes is placed in the tub and the pump operated'to draw the suds from the vat back into the tub and the washingoperation repeated. 7 In this manner the same suds may be employed to wash several tubsful of clothes whiletherinsing water is dischargedfree of. the vat without intermlngllng with thesuds.

In Figs. 6 and 7 I have shown in connection with my tub 25' a supplemental tub 52 perforated as at 53. This tub is considerably through the member 26 and holds under C0111- pression the spring 49 to 'yieldingly resist the upward movement of shaft 19 and at the same time holds the tub 52 upon the conical member 26. This tub 52 isadapted to receive a relatively limited number of clothes centering them about the axis of revolution of 1 the tub 25, thereby minimizing the vibration of the tubduring its rotation.
