A drain II] in the sink bowl l is connected to waste pipe I I.

In the drainboard 2 is a circular opening which set portion about the tub opening providing a narrow circular flange I6 which supports a radially outwardly directed flange 11 formed about the upper edge of the tub side wall 12. A sealing gasket [8 of rubber or cork is interposed between the flanges l6 and f1.

In the tub bottom I is a drain opening 19 which is connected by a conduit 20 to a T 2| 1n A shut-off valve 22 is proso that washing liquid the washer tub or the waste pipe ll. vided in the conduit 20 may be either retained in drained therefrom as desired.

The power unit for actuatirig'the washer is in the form of an integral assembly mounted on the tub bottom and comprises a housing structure 24 that is secured in place by screws 25 that extend through the tub bottom 15 and are threaded into bosses formed in top wall 26 of the housing. An integral guide sleeve or journal 21 is formed at one end of the top wall 26 of the housing and extends upwardly through an opening in the bottom [5 of the tub. Through the opening in the guide sleeve 21 extends a. drive assembly comprising an outer tubular quill 28 and an inner shaft 29, the shaft being rotatable in the quill and guided in

bushings

30 and 3|. A flanged bushing 32 is interposed between the quill 28 and the guide sleeve 21.

The shaft 29 is longer than the quill 28 and extends through both ends of the latter, the lower end of the shaft continuing through the chamber in the housing, through a guide sleeve 34 in a cover 35 attached to housing bottom 36 and terminating in a coupling 31 which drivingly connects the shaft to shaft 38 of an electric drive motor 39. The motor is disposed with the shaft 38 vertical and is attached to the housing cover 35 by screws 40. Thus the motor 39, shaft 29, quill 28, and guide sleeve 21 are in coaxial relationship for rotative movement of the shaft and quill about a common vertical axis. A seal 4| surrounds the lower end of the shaft 29 and is received in a recess-formed in the lower end of the guide 34, to prevent loss of lubricant along the shaft out of the housing 24. r

A bevel gear 43 is secured on the shaft 29 by a pin 44 and bears on the'upper end of the guide sleeve 34 to support the shaft. A sleeve 45 surrounding the shaft 29 bears on the upper end of the gear 43 and is formed at its upper end with a circular flange that engages a radial flange formed on the lower end of the bushing 3|, thus serving as a support for the quill 28. An intermediate drive shaft 46 is supported horizontally for rotation within the housing 24, being journalled in integral bosses or

bracket elements

41 and 43 extending into the housing chamber from the housing walls. A bevel gear 49 meshing with the bevel gear 43 is secured by a pin 56 on that end of-the shaft 46 which is adjacent the vertical shaft 29. A worm 52 is secured on the other end of the intermediate shaft 46 by a pin 53 and meshes with a worm gear 54 secured adjacent the lower end of a reduced diameter portion 55 of a vertical driven shaft 56. The shaft 56 is disposed outside the tub wall l2 and extends downwardly through a grease seal 41 received in a circular recess formed on the outside of a boss in the top wall 26 of the housing. A circular shoulder 58 at the juncture of the reduced diameter portion 55 and the full diameter portion of the shaft 56 bears on a washer 59 that seats in the grease sealrecess and supports the shaft and the parts carried by the latter.

Rotation of the worm 52 turns the worm gear 54 and the shaft 56 at relatively low rotational speed, the shaft 46 being driven at approximately the same rotational speed as the impeller drive shaft 29 by the

bevel gears

43 and 49 which are of approximately the same size.

On the lower end of the reduced diameter shaft portion 55 is secured a crank 60 which carries one end of a connecting rod 6|. The other end of the rod is received on a pin in an arm 62 formed as an integral radial extension on the lower end of the quill 28. The arm 62 includes a flange portion 63 which underlies the guide sleeve 21 of the housing and limits upward movement of the quill in the sleeve. The crank 60 is of less length and throw than the quill arm 62 so that as the shaft'portion 55 is rotated, the rod 6| is moved back and forth by the circular movement of the crank 66 oscillating the arm 62 over an arcuate path of about to about or more, but less than and thereby imparting reciprocating rotative movement to the quill 26. Such rotative movements of the quill while occurring in simultaneous timed relation to the rotary movement to the shaft 29, are at a relatively slower rate of speed than that of the shaft. By reason of the speed reduction effected through the form 52 and worm gear 53 the torque imparted to the quill 28 is higher than that of the shaft 29.

The end of the intermediate shaft 46 extends through a partition 65 inside the housing and drives a small spur gear 66 mounted on the shaft. A larger gear 61 secured on a short shaft 68 meshes with the spur gear 66 and is driven by the latter at a relatively slower rotational speed. The shaft 68 is journaled in an elongated boss 69 formed in an end cover plate 10 of the housing 24. The inner end of the short shaft 69 is guided in a journal boss formed in the partition 65. Outer end 12 of the shaft 68 is formed square or non-circular in shape to receive and drive a coupling of a flexible power transmission shaft assembly, not shown. Such coupling may be held in place as by a collar screwed onto threads 13 formed on the outer end of the journal boss 69. Thus a power take-off is provided for turning a. flexible shaft assembly at an intermediate rotative speed, slower than the shaft 29 and faster than the oscillatory movements of the quill 28 and the shaft 56 which, as will later appear, drives the wringer.

. Clothes washing When the washer is to be used for the purpose of washing clothing and other fabric materials an agitator A is placed in the tub and mounted on the dual drive column. The agitator comprises a central post 14 the lower portion of which is hollow and receives the quill 26. The upper end of the quill is of hexagonal or other non-circular shape as indicated at 15 and has interfitting driving connection in a similarly shaped socket formed interiorly of the post so as to establish a driving connection between the quill and the agitator.

Adjacent the upper end of the guide sleeve 21 and the

quill

2,8 is formed with .a circular sectioned guide portion 16 that is-slidingly received in the lower end of the agitator post 14 to locate and stabilize the agitator in the tub and prevent lateral swaying and twisting of the agitator in use. A wide circular flange H is formed integrally on the bottom of the agitator post M and a number of upright vanes or wings T8 are disposed in the angle between the agitator post 14 and the flange TI. The agitator may be cast integrally of light material such as aluminum or of a plastic material such as a phenol formaldehyde resin.

The chamber within the agitator post Hi is extended upwardly beyond the socket portion which receives the hex-end E of the quill to provide a clearance chamber 80 which receives upper-end 8| of the impeller drive shaft 29. The shaft end 8| is square or of other non-circular section so as to be capable of establishing a driving connection with the impeller as will later appear. Since'the shaft rotates at a relatively high speed while the quill oscillates at a relatively low speed, it is es-. sential that the shaft turn freely in the agitator. Accordingly, the chamber 80 is made of suificient sizev to provide clearance between the agitator post and the shaft end B I.

A water soap solution or other washing liquid is introduced into the tub approximately to the level indicated at 82 the valve 22 being closed and the motor 39 is energized from a suitable source of electric current through a switch 83 which may be mounted on splashboard 4 of the sink structure. Clothing and other similar items to be washed are placed in the liquid in the tub and subjected to the washing action of the liquid which is moved first in one direction and then reversed by the reciprocating movements of the agitator A. A cover 84 is placed over the tub to prevent escape of washing liquid. When the washer is not in use this cover, being flat, serves as a work table or counter. The washing action of the present machine when operating with the agitator A is quite similar to that of conventional type agitator washing machines.

A wringer 85 of conventional construction and having the usual rubber covered

rolls

86 and 81 is formed at one end with a depending hollow supporting post 88 which has a reduced diameter or plug end portion89 receivable within a cylindrical socket formed in a cup 90 mounted in the drainboard of the sink. The cup journals the upper end of the vertical shaft 56 and has an outwardly directed radial flange 9! around its top, this flange being supported on a downwardly offset circularflange 82 formed in the drainboard 2.

A sealing gasket 93 is disposed between the cup flange BI and the supporting flange 92 and the parts are drawn and held together by a threaded collar 94 received on a threaded portion of the cup. A number of integral radial ribs 95 are formed in the bottom of the cup 90 and are engaged in mating notches formed in the lower end of the reduced diameter portion 89 of the wringer post 83. The interengagement between the ribs 95 of the cup and the mating notches of the wringer post hold the wringer assembly in predetermined rotative positions and prevent bodily turning of the wringer with respect to the drain board. Thus the wringer is supported cantilever fashion on the post 88 and can-be swung to and retained in any desired operation position, or the wringer may be removed bodily from the socket to clear the drainboard for other uses.

The wringer rolls 86 and 81 are driven through suitable mechanisms, not shown, by a shaft 96 thelower end ofwhich is, guided in abushing 91 held, by a pressfitin an axial bore formed in reduced diameter or plug endportion 89 of the wringer column. The lower end of the wringer shaft 96 abuts and drivingly interfits with the upper end of the vertical shaft 56, a diametrical key 98 being formed on the latter and interfitting in a corresponding diametric slot in the shaft 96 to establish the driving connection between the shafts. In this manner the wringer rolls 86 and 8"! are driven by themotor 39.

When the wringer is not. in use the'plug end 89 of the wringer post is lifted out of the socket of the cup 9i! and the wringer is stored elsewhere. In such case the socket is closed by a suitable threaded cover, notshown, threads being provided in the upper end of the socket for this pur-. pose.

Dish washing The machine of the present invention can be used alternatively as either a clothes washer or a dish washer. To convert 'to dish washing the agitator A is removed and replaced by an impeller I (Fig. 5). This'impeller which may be made by casting of a suitable light metal or plastic comprises a circular sectioned hollow hub Hit which is received over the drive column and is supported on the upper square end 8| of the shaft 29. A matching socket is provided in the upper end of the hub chamber to receive the square end 8| of the drive shaft 23 so that the impeller is actuated by the latter to turn at high rotational speed such, for example; as about 800 to about 1800 P. M., the latter being preferable. The hollow interior of the impeller hub H19 includes a chamber portionllll sufiiciently large to accommodate and provide a clearance around the hexagonal drive end 75 of the quill 28 so that the impeller be rotated relative to the quill.

Adjacent the lower end of the impeller the walls of the internal hub chamber are formed to closely surround the cylindrical guide portion 76 of the quill 28 so that the impeller although turning relative to the quill is guided by the latter. A metal insert bushing I02 may be cast in place in the impeller to rotate on the quill guide 15.

A pair of helical scoopsor vanes I 84 extend radially out from opposite sides of the impeller hublllli. Each of the scoops [M is of trough-like form and at the bottom of the. hub terminates in a substantially straight radially extending bottom edge H15 which is disposed closely adjacent the surface of the tub bottom 15. The impeller vanes Hi4 maycarry integral concentric partition walls 563 which form open topped channels I [3 closed at their upper ends. At high rotational speeds the impeller I, rotating so as to advance the radial edges H35 ofthe scoops into the washing liquid in the tub picks up such liquid and raises it along the scoops I84 and throws it radially outward over dishes and other articles being washed. Radial holes 523, in the vanes HM release the washing liquid from the impeller scoops. For

,. dishwashing purposes a smaller quantity of washing fluid is used than for washing clothing. For example, the washing liquid, which may be a soap solution or a water solution of any other conventional detergent, is placed in the tub up to about the level indicated at I96 (Fig.5).

Dish basket To support the dishes and otherhardware items being washed a removable-basket structure B is placed inlthetub over theimpellerl. This basket is composed of wire'or rod elements that are preferably stainless steel or other non-rusting metal or they may be plated metal if desired. A number of peripheral rod uprights I01 are held in spaced generally parallel relation to one another by top hoop I08, intermediate hoop I09 and bottom hoop I I to the outside of which the uprights are individually welded or soldered. The bottom ends of the uprights I0'I, or some of them, are curved inwardly corresponding to the contour of the tub and form supporting feet II2 of the basket. Lengths of rubber tubing I I I are frictionally received on the basket feet I I2 and serve as cushions to contact the surface of the tub bottom I5.

The upper ends of the uprights I0'I, or some of them, are curved inwardly and downwardly over the top hoop I08 providing angularly disposed guide portions H4. The ends of the guide portions II4 on the tops of the upright rods terminate in inwardly directed radial portions II5 which are welded or soldered to the underside of an inner hoop II6 of less diameter than the top hoop I08.

Within the basket B provision is made for supporting a number of dishes in several similar groups. Fig. 7, showing the plan of the basket, illustrates a novel scheme for accommodating 5 groups of dishes each comprising a series of plates of decreasing sizes. Large plate P-I of each group is disposed obliquely across the tub and basket ahead of intermediate plate P-2, the latter being ahead of small plate P-3. The dishes are all supported in generally upright positions, the dishes of each group being one behind another and the several groups being generally radially disposed about the impeller I or central source of the cleansing spray. In each group, the several dishes are located at diiferent distances from the spray source or impeller. For example, the intermediate dish P-2 is further away from the source than the large dish P-I and the small dish P-3 is further still from the source of the spray liquid. This arrangement positions the relatively large or dinner plate which is apt to be the most soiled and the hardest to cleanse, relatively close to the spray source while the other plates which may be the salad and butter plates are relatively further away from the spray source.

It is also to be noted that the plane of each dish, which may be taken as the plane of the dish periphery, is disposed at an acute angle to the planes of the other dishes of the same group. This non-parallel arrangement improves the washing action and promotes the break-up and distribution of the cleansing spray as released from the impeller. Also it is to be noted that each of the dishes faces generally in a non-radial direction with respect to the center of the tub and basket.

To support the dishes in the positions shown a number of wire or rod elements are supported in the basket by cross bars I I1 and I I8. The cross bars Ill extend from the bottom hoop III] in a generally radial direction to a center hoop II9 to which they are welded or soldered. The cross bars II8 extend from the bottom hoop IIO to which they are secured to an adjacent cross bar III to which they are also secured. The cross bars Ill and H8 are arranged in pairs, one pair for each group of .dishes to be supported in the basket. The bars of each pair are somewhat divergent to'accommodate the different sizes of dishes, the edges of which fit down between the cross bars. The more widely spaced parts of the cross bars are adjacent to the large dishes corre-' sponding to the dish P-I.

Between the cross bars are arches formed of bent wires or rods having divergent side elements I20 and I2I and top cross elements I22. The ends of the side elements of each arch are secured to the cross bars II I and H8 so that the arches extend upwardly from the cross bars to engage the bottoms of the plates which are propped against the arches and are inclined backwardly a few degrees so that water impinging against the upper portion of the plates flows downwardly by gravity over the plate surface'in a cleansing action.

Above the impeller I a wire mesh basket I24 is supported by upright bars I25, the lower portions of which are divergent to clear the impeller and the bottom ends of which are secured to the small hoop II9. Hoops I26 and I2'I support and surround the basket I24 to protect the latter and are secured to the uprights I25. Cutlery and small items to be washed are placed in the basket I24 and receive the liquid spray directly from the top of the impeller I.

Cups, small saucers and the like are disposed on a tray structure comprising an outer hoop I28 and inner hoops I29 and I30. A number of radial bars or rods I3I are secured at their outer ends to the large hoop of the tray structure and have inner ends which are bent to provide vertical uprights I32 which are secured to the insides of the hoops I29 and I30. The interior of the tray structure is thus clear so that cutlery in the basket I24 may extend upwardly through the hoops I29 and I30. The tray hoop I28 is of less diameter than the top hoop II8 of the basket while being of greater diameter than the small hoop IIB carried by the guide portions II4 of the basket uprights. Thus the tray structure may be supported on the guide portions I I4 of the basket uprights, the tray hoop II8 interlocking or embracing the basket hoop II6 to prevent lateral displacement and tipping of the tray.

During operation as a dishwater the liquid is picked up from the bottom of the tub by the impeller I and thrown upwardly and outwardly from the vanes or scoops I04 in a helter-skelter deluge which flows over the surface of the plates and dishes stacked in the basket and cleanses the same. Some of the cleansing liquid, especially the larger droplets thereof, bounce from the surface of one dish to another so that those dish surfaces not in direct line with the spray from the impeller are washed by secondar liquid streams received from other items being washed. There is, of course, some bouncing of the water or other cleansing liquid from the walls I2 of the tub onto the dishes and plates contained therein.

After the washing has been continued for a sufiicient length of time to cleanse the dishes, the valve 22 is opened and the cleansing fluid drained out of the tub. Thereafter the washing water may be rinsed from the dishes by hot water introduced through a hand spray attached to the spigot 9 or directly from the spigot itself.

When used as a dishwasher the wringer is, of course, removed and stored elsewhere and the cover 84 is used to prevent loss of cleansing liquid from the interior of the tub. Should any of the dishes be extremely difficult to cleanse or if it is desired to scour pots and pans in the sink I, a suitable flexible shaft is attached to the power take-oil shaft 68 and used to drive a rotary brush or bufiing wheel.
