Referring now to the drawings, the machine illustrated comprises a suitable support II) having a substantially at supporting surface at its top and a downwardly extending skirt or apron enclosing and concealing the operating devices of the machine. The support I0 is preferably carried by a series of legs a fragmentary portion of only one of which is indicated in Fig. 1.

Four such legs may be employed to provide a sturdy support. On the upper surface of the support I0 there is mounted a washing compartment or tub I2, preferably cylindrical in form, and a similar cylindrical compartment or chamber I3 for the dryer. As shown, the dryer compartment may be considerably smaller 1n diameter than the tub, although its height is preferably the same. To eliminate vibration and noise as much is possible, the tub I2 is preferablyy supported adjacent its periphery by a rubber ring I4, orthe like, while the dryer chamber may be similarly supported by means of a rubber ring I5, or the like.

To the under side of the horizontal portion of the support I0 there may be suitably attached a bracket I6 having downwardly extending arms arranged to carry' a motor I1. The armature shaft I8 of the motor is connected by a universal coupling I9 with a shaft 20 journaled in a gear casing 2|. This gear casing is suitably attached to the support I0 and has an upwardly extending neck 22 passing through an opening in the support Ill and through an opening in the bottom of the tub I2. A cooperating sleeve member 23 may serve to clamp the support and tub bottom together, This construction may suitably be of the form comprising a suitable stuffing box construction and other means may be employed within the sleeve 23 and the top of the gear casing to prevent leakage of water from the tub. A shaft 24 suitably journaled in the gear casing and sleeve 23 may carry a torque-block 25 at its upper end adapted to receive and drive an agitator 26, which may be held in place on the shaft by a screw 21. The agitator 26 may be of any suitable construction but one that will produce violent agitation and movement of the water, such as a single vane construction of the type disclosed in the previously mentioned Davis patent, is preferable.

Any appropriate means may be provided for imparting an oscillatory or other rotary movement of suitable magnitude and speed to the shaft 24. For this purpose the shaft 20 may carry a worm adapted to mesh with a wormwheel 28 carried by a stub shaft 29 suitably journaled in the gear casing. A pin eccentrically mounted on the worm-wheel may be connected by a link 3| with a pin 32 carried by a segment 33 mounted on a xed pivot 34 within the gear casing. Segment 33 meshes with a broadtoothed pinion 35 forming part of a clutch unit having at its upper end a toothed member 36 adapted to cooperate `with an internally toothed member secured to the shaft 24. As will be understood, the clutch member -35 is free to turn upon the shaft 24 but when lifted to engage the toothed portion 3S with the internally toothed member of the clutch, the shaft 24 will be oscillated in accordance with the movements of the segment. Preferably the shaft 24 will be caused to turn in this way through an arc of between 175 and 225 at a speed of between E30-and 75 complete to and fro movements per minute. Any appropriate means may be provided for lifting the clutch member 36, including, for example, a lever 36| (Fig. i4) connected with a link 31 operable by a two-armed lever 31| which in turn is operated by a rod 38. This rod is slidable longitudinally in suitable supports (not shown) by means of a knob 39 (Fig. 2) carried at its upper end. Upon depression of the knob the lever 31| is shifted to the broken-line position of Figure 14,an over-center spring 312 assisting in the final part of the movement, and the clutch is thereby engaged. If the clutch teeth are not properly alined when rst brought together, a spring (not shown) in the connection 31 will yield temporarily until the teeth are alined. The knob 39 may be locked in depressed position in any suitable way, as by turning the same, to carry a pin on the shank thereof beneath some part of the casing. When it is desired to release the clutch the knob may be simply turned to aline said pin with a slot so that a spring, capable of lifting the rod against the action of spring 312, will restore the parts to the full-line position of Figure 14. The pin and spring, just mentioned, are not shown but may be similar to those associated with the spinner control knob |33, to be later described,

The tub I2 is preferably provided at its center with a depressed well 40 into which the bottom disc portion -of the agitator 26 may be set with a relatively close t. From the top of the well the portion 4| of the bottom of the tub preferably slopes upwardly at a slight angle toward the side walls of the tub. A gentle curvature is preferably employed, as indicated at 42, between the bottom and side walls of the tub. This arrangement enables the free, easy movement of the water and clothes outwardly and upwardly as the agitator is oseillated. At the top of the tub the side walls are curved inwardly along a sweeping are of relatively large radius, as indicated at 43. This curved portion at the top is preferably made integral with the side wall.

In the oscillation of an agitator of the single vane type, currents of water are thrown violently outward toward the wall of the tub and these currents travel upwardly as well as around the wall with considerable momentum and velocity, It has been found that if the tub is provided with an opening at the top substantially equal to the diameter of the side walls, or if the top is simply closed partially by a flange extending inwardly at a sharp angle from the side walls, there is a tendency for all or part of the water to move straight up through the opening at the top, lifting the cover if one is applied over the opening. However, when the top of the tub is curved inwardly, in the manner shown in Fig. 1, the upward movement of the water is gradually converted into an inward movement and there is no tendency for the water to lift the cover or splash out of the tub. Even though the upwardly moving wall of water may be of substantial thickness, the curvature 43 at the top of the tub is sufficient to direct the water inwardly across the top of the tub without rising above the top of the tub, particularly when clothes are mixed with the water. Preferably the inner edge of the curved portion 43 is formed to provide a slight neck 44 at the top of-thetub, which may conveniently receive a rubber gasket 45 to support-a cover member 46. 'I'his construction places the bottom of the cover slightly above a line tangent to the curved surface 43 adjacent its inner edge. Accordingly, there will be no tendency to lift the cover and cause water to be splashed out of the machine.' It should be observed in connection with this feature of the construction that the problem referred t'o above does not arise when a multiple vane agitator is used. The character of the water current set up by the common multiple vane type of agitator is such thatthe Water does not tend to rise appreciably above its normal level and therefore does not tend to lift the cover and splash out of the machine.

Turning now to the drying unit, there is provided within the chamber or compartment I3 a perforated basket 41. This basket is preferably substantially cylindrical but with its upper end sloping inwardly to partially close the same. Substantially the entire vertical wall is provided with a series of perforations to permit the discharge of water as the basket is rotated at a high speed, in the manner to be explained. The bottom of the basket is preferably formed by a casting d, having an upwardly extending portion di) at its center provided with a sleeve 5t adapted to snugly receive the upper end of a shaft 5i. A

pin l5i?, carried by the projection 9 adjacent its upper end, is adapted to t into a notch or groove 53 in the upper -end of the shaftl. In this way the rotation of the shaft is imparted to the basket. The upper end of projection 69 is preferably closed by a screw cap 56, or the like.

Shaft 5I is journaled in a bearing sleeve 55, formed of bronze or other good bearing material, mounted in an extension 5S of 'a casing 51.

The extension 56, as shown, is preferably pro- `vided on .a separable cover member ,bolted to the main portion of the casing 51. At its lower end this casing is formed with a downward extension 58, preferably square in cross section. l A rubber projection 59, similarly square in cross section, surrounds the projection and fits' withinV a pocket provided by a member 50. The latter is carried by a strap El secured by bolts 62 to a bracket 63 suitably secured to the main support I0. The .member 60 is preferably secured to the strap 6I by means of bolts 64 passing through elongated slots 65 in the strap. This arrangement is such that the angular relation between the member B and the strap 6| may be varied slightly to properly aline certain shafts, the necessity for which will be made clear hereinafter. Beneath the strap 6l there is provided a disc B6 of rubber or other resilient material, preferably having a reduced portion extendingthrough an opening in the strap and engaging the lower end of' the projection 58. A metal plate or washer E1.is provided beneath the disc 66 and a bolt 68 is employed to retain these parts in assembled relation. It will be apparent that through the construction described the casing'51 will be supported by the 4strap 6I in a position to maintain the axis of the shaft l substantially vertical. However, due to the rubber or other resilient bushing 59 and disc B6, the casing may be tilted slightly in any direction. v

In order to assist in maintaining the substantially vertical allnement of the shaft 5l Without, however, rigidly confining the shaft, resilient means areprovided for applying forces of the character hereinbefore specified at a point some distance up from the lower end of the casing 51. For this purposel a collar 69 is provided around the extension 56 of the casing, this collar being rigidly secured to the extension and having a pair wings is provided with a pair of apertures to receive the ends of springs 1i. The opposite ends of these springs are attached to pins 12, each carried by a bracket 13 secured to the under side of the main support IU. The pins 12 are threaded for at least a portion of their length to receive nuts 1d which may be adjusted to any position desired and locked therein in any suitable. way. By so adjusting these nuts the tension on the various springs 'il may be varied to suit the particular requirements. It will be observed that the springs 1l are not uniformly distributed around the axis of the casing but are arranged to apply a greater restraining force to the movement of the casing in certain directions than in others. It will be appreciated that when the basket is being rotated at high speed, the uneven distribution of the clothes therein will tend to produce a greater centrifugal force at the point Where the load is in excess. As a result of this uneven distribution of the load, the upper end of the shaft 5i will have a tendency to move in a gyratory path as it rotates. If an attempt were made to rigidly confine the shaft with relation to the main support l0, the forces tending to move the shaft in a gyratory path would beimparted to the frame and would thus set up very objectionable vibrations therein. However, these vibrations are eliminated or reduced to an unobjectionable minimum by the application of resilient forces to the shaft, in the manner disclosed, to retain it infor restore it to its normall position. As the machine is set into operation, the upper end of the shaft 5I tends to move in a gyratory or orbital path but the magnitude of this path is very quickly reduced by the action of the springs ll as the basket attains the desired speed. Suffice it to say, without attempting to explain the reason for it, the non-uniform arrangement of the springs 1i assists very materially in promptly reducing the extent of the gyratory motion and preventing it from attaining an objectionable magnitude.

Means are preferably provided for effecting a seal at the bottom of the container |'3 to prevent the discharge of water along the shaft 5I. l For this purpose a member 15 is provided around the' shaft, this member having a laterally extending flange at'its base which may be secured tol the bottom of the container I3. A gasket 16 is preferably provided between the member 15 and the bottom of the container. such as screws 11, may be employed for securing the' member 15 to the container bottom. Member 15 extends upwardlyinto a recess formed in the bottom member 48 of the basket. The top of the member 15 is thus maintained at a level normally above the level at which water will accumulate within the container. should water rise above this level, it is prevented from passing downwardly between the member 15 and shaft 5l by means of a iiexible diaphragm 18 formed of rubber or other suitable material. This diaphragm preferably has an annularportion, U-shaped in cross-section, fitting over the upper end of the member 15 and has another annular portion surrounding a sleeve 19 secured to the shaft 5I. A suflici'ently tight t is provided between the diaphragm and the sleeve 19 to substantially prevent the passage of any water along the shaft. However, should any small amount of water nd its way along the shaft it will be deflected by an outwardly flaring shield of laterally projectingwings 10. Each of these carried by the shaft beneath the sleeve 19. This shield or deflector will divert such water Any suitable means, Y

However,

outwardly over the extension 56 and will prevent its passage into the interior of the casing 51 which carries a lubricant.

The lower end of the shaft is reduced in diameter and is surrounded by a sleeve 8|, Figure 15, which fits snugly in a recess 82 in the extension 58 of the casing 51. Moreover, the lower end of shaft 5| is formed with a recess 83 carrying a seriesof balls 84, the lowermost of which extends slightly beyond the lower end of the shaft and bears against a disc 05. Beneath this disc is a large ball 86 supported by a disc 81 carried at the lower end of the recess 82. In this way the vertical thrust of the shaft 5|, to. gether with the basket 41, is transmitted 'to the casing 51.

Mounted on the sleeve 8| and secured thereto is a spiral gear 88 adapted to mesh with-a similar spiral gear 89 (Figs. 10 and l5) secured to a shaft 90 carried by bearings 9| and 92 integral with the casing 51. The end thrusts of the shaft 90 are taken by a disc 93, ball 94 and a second disc 95 mounted in the end of the recess forming the bearing 92. Shaft 90 is connected by a universal coupling 96 with one end of the shaft I8 of motor I1. As best shown in Figs. 1 and 5, the motor shaft I8 is connected at one end to drive the agitator of the washing machine and is connected at its other end'to drive the basket of the dryer. Adjacent its upper end the sleeve 8| is provided with a laterally extending ange 91 to which is secured a disc 98. Normally the weight of the sleeve 8| and its connected parts will be suflicient to cause the latter to rest upon the bearing disc 85. However, the arrangement of the teeth on the' spiral gears 88 and 89 is such that in driving the sleeve 8| against any substantial resistance, the sleeve will be raised until the disc 98 strikes a shoulder 99 (Fig. l5) formed slightly above it by enlargement of the shaft 5|. This will serve to lift the lower end of sleeve 8| from the disc 85 and eliminate friction at this point. Continued upward movement of the sleeve due to the vertical thrust produced by the spiral gears will tend to lift the shaft 5| and the basket. However, the arrangement is such that in the normal operation of the machine the various forces acting upon the shaft 5| are substantially balanced-so that friction is reduced to a minimum but the basket is actually not lifted to any appreciable extent.

'Ihe portion of the shaft 5| directly below the bearing is provided with a series of splines |00 cooperating with internal splines on a vsleeve member |0|. This sleeve member is, therefore, adapted to be rotated with the shaft and may be shifted longitudinally of the shaft. The lower end of the sleeve member is provided with an annular flange |02 carrying an annular friction member |03 adapted to cooperate with the disc 9B. A spring |04 compressed between a collar |05 secured tothe shaft 5| and the upper end of sleeve member |0| urges the latter downwardly to provide frictional driving engagement between the members 98 and |03. So long as this frictional engagement is maintained the basket 41 will be rotated, ige., whenever the motor I1 is in operation. To disconnect the basket from the motor the sleeve member |0| must be lifted to disengage the friction surfaces. For this purpose member |0| has secured to its upper end an annular plate |06 arranged to be engaged by a friction element |01 carried by an annular member |03. Member |08 is provided with a pair of downwardly extending ears |09 connected with opposite ends of a yoke ||0 by means of pins I|I. Yoke II.0 is secured to a shaft II2 carried by bearings provided in an extension of the casing 51. A screw |,I3 cooperating with a notch or cutout portion of the yoke I|0 serves to retain the latter and the shaft |I2` against axial movement without, however, preventing a limited rocking movement of these parts. vAt one end of the shaft II2 there is secured an arm ||4 carrying at its free end a roller ||5. 'At the plane of the roller |I5 there is provided an arm II6 carried by a stud I1 mounted on the frame of the machine.

The free end of arm ||6 is formed with a camming surface I I8 arranged to engage the roller |I5 as the arm is rocked downwardly and thereby rocks the shaft ||2 counter-clockwise (Fig. 1a) to lift the member |01 into engagement with member |06 and upon the continued movement of member |01 the sleeve |0| will be raised against the action of spring |04. This serves not only to break the driving connection between the members |03 and 90 but also applies a brake between members |06 and |01 since the latter is held fixedly against rotational movement.

For the purpose of rocking the arm |I6 in the manner explained, it has integrally or otherwise connected therewith an arm I|9 to which is at tached a spring |20, the opposite end of which is connected with the frame of the machine. It will be apparent that spring |20 tends to rock the parts in the direction in which surface IIB will engage roller |I5 to disengage the friction clutch and apply the brake in the manner explained. When it is desired to operate the dryer, itis necessary to depress the arm I|9 against the action of spring |20. For this purpose the arm is bifurcated at its outer end, as indicated at |2I, and is fitted between nuts |22 carried at the lower end of a vertically extending rod |23. The upper end of this rod slides in an apertured guide member |24 carried by a member |25 carried at the ,top of the machine and forming a closure for the space between the tub I2 and drying chamber I3. A collar |26 secured to rod |23 abuts against the lower side of the guide member |24 to limit the extent of the rocking movement of the arm ||9 by the spring |20. The top member |25 has an annular rim |21 adapted to t over a gasket v|28 carried at the top of the chamber I3. A detachable cover |29 is arranged to close the top of the chamber I3 and for this purpose is provided with an annular sealing member |30, formed of rubber or the like, extending around its periphery and adapted to rest upon the upper surface of the rim |21. At one side of the cover there is secured, as by means of rivets or the like, a bracket I3| terminating at its outer end in a vertical guide sleeve |32. In this sleeve there is mounted, for both rotary and axial movement, the shank of a control knob |33. To this knob is attached a downwardly extendingV rod |34 in axial alinement with the rod |23. A pin |35 extending through the rod |34 may be alined, by proper rotation of the knob |33, with an elongated passage |36 formed through a boss on the top member |25. When the pin and passage are alined a spring |31 serves to urge the knob into the dotted-line position of Fig. 7, in which the pin engages the surface |38 within the sleeve portion of the bracket |3|. This lower portion of the sleeve may b'e conveniently so formed as to hold the pin, and hence the knob, in a definite position so that when the cover is in place the pin will be properly alined with the passage |36. The

knob, when depressed into the full-line position shown, may be rotated to place the pin at right angles to the passage |36 and thereby retain the knob in its depressed position. This also serves to lock the cover |29 with relation to top member 25. When the knob is depressed and locked in this position, furthermore, the lower end of rod |34 will engage and depress the rod |23 against the action of spring |20 and rock the arms IIB and ||9 into the positions indicated in Fig. '1a. This will permit the spring |04 to slide the member |02 out of braking position and into frictional engagement with the driving member 98.

A suitable drainage system is provided for discharging the water from the tub I2 at the end of a washing operation and also for discharging the water from the chamber I3 during the operation of the dryer. For this purpose a valve chamber |39 is provided to receive the water from both the tub and the drying chamber. A tube |40 extending upwardly at a slightangle to the horizontal from one side of the valve chamber is provided with a-iitting |4| at its end attached -to the bottom of the tub to receive the water therefrom when desired. A substantially vertical branch of the valve chamber is provided with a flange |42 adjacent its upper end, arranged to cooperate with the bottom ofthe drying chamber I3. A tting |43 within Vthe chamber i3 serves to clamp the valve chamber to the drying chamber and serves also as a strainer for this inlet to the valve chamber. As shown, the fitting |43 preferably is located in a slight depression |44 in the chamber 3. A shaft |45 extending transversely through the chamber |39 has secured to it a T-shaped valve support member |46 carrying a valve-|41 at the end Pof one of the arms,

arranged to cooperate with a valve seat |48 at` the linner end of the line |40. A similar valve member |49, carried by the end of the other.

arm of the support |46, is arranged to cooperate with a seat |50 in the Apassage from the 'drying chamber. A pair of springs |5| (Fig. 4), suroundingthe shaft |45 and abutting opposite sides of .the valve chamber, serve to retain the valve structure in a properly centralized position.

The arrangement of the 'spring |54 is such that it serves to hold the pair of valves in either of their extreme positions. As the valves are shifted past dead center, the spring |54 will assist in swinging them to close one passage and fully open the other. Intermediate the ends of the shaft |45 there is secured an arm |56 having a foot |51 (Fig. 7a) adapted to swing beneath the rod |23. When the parts are in the positions shown in Figs. 7 and 7a the valve leading from the drying chamber is open. It is not possible to reverse the condition of the valves due to the abutment of the foot |51 with the lower end of the rod |23 as soon as manual rotation of the shaft |45 is attempted. This insures proper drainage of the water from the drying chamber so long as the spinner basket is in operation and .prevents the discharge of water from the tub at Vthis time. Furthermore, should the valves be in the opposite position at the time the sapinner is vthe Water from the valve casing |39 and discharging it into a stationary laundry tub or any other suitable receptacle. This pump may com-` prise a pump chamber |58, (Figs. 1, 4, 5 and 6) carried by a series of rods |59 extending from 1 the housing of the motor l1, in a direction parallel with the axis of the motor. A rotor carried by the shaft |8 of 4the motor operates within the chamber |58 to pump the Water as desired. A connection I 60 is provided between the intake side of the pump and the discharge side ofthe valve casing |39, while a hose or tube |6| is connected with the discharge side of thev pump to convey the water to any desired point. A flexible hose may be provided for this purpose to enable convenient discharge of the water into any suitable receptacle.

Referring to Figure 2, there is shown a drainboard |62 which is adapted to be moved into any one of a plurality of different positions. For this purpose there is attached, by welding or the like, to the underside of the drainboard, a pair of lugs |63, each having a downwardly projecting foot portion adapted to enter one of a series of slots or apertures formed in projections |64 extending from the edge rof the member |25. These slots are appropriately spaced and located to permit the drainboard to assume any one of a number of different positions, three such positions being indicated.

, It is believed that the operation of th machine will be clear from the foregoing detailed description of its various parts. A brief rsum may be given, however, for convenience. The clothes to be laundered are rst placed in the tub l2 with a suiiicient quantity of water to provide an em- `cient washing action. The motor I1 is then set into operation by throwing a suitable switch and the knob 39 is depressed, and locked by turning the same, to engage the clutch member 36 with its cooperating member to set the agitator 26 into operation. After a desired washing period the knob 39 is turned to release the clutch and the clothes are removed from the tub |2 and placed in the basket 41 of the dryer. The lid |29 of the dryer is then set in place and the knob |33 depressed and rotated to place thepin |35 crosswise of the passage |36. Depression of the knob in this way depresses the rod .|23 which in turn rocks the arms I9 and H6 against the action of spring .|20 and permits the spring |04 to slide the member |0| downwardly, thereby disengaging the brake surfaces and engaging the friction clutch surfaces. This will set the bspinner basket 41 into rotation. As the speed of rotation increases, the supporting shaft 5| will receive a gyratory movement which will increase in magnitude at the beginning but, when a certain speed is attained, will be reducedv in magnitude by the action of the non-uniformly distributed springs 1|. If the valves |41- and |49 were not inthe correct position to permit discharge .of the water from the chamber I3 when the knob |33 was depressed, the depression of this knob and the rod |23 would swing the valves into the correct position by the engagement of the lower end of rod |23 with the foot |51. Upon completionvof the drying operation the knob |33 issimply rotated to aline the pin |35 with the passage |36 and the cover |29 is thereby released. Spring |20 then takes eect to rock the arm ||6 downwardly engaging the roller to lift the brake member |Il`| into engagement With the member |06. This also lifts the member |0| to discngage the friction clutch faces 99 and |03.

While an illustrative embodimentI of the invention has been described in considerable detail, it will be understood that numerous changes may be made in the construction and operation of the various parts without departing from the general principles and scope of the invention. The terms and expressions employed herein are to be regarded as terms of description andnot of limitation.

This application is a division of my copending application Serial No. 86,522, filed June 22, 1936, and which copending application describes and claims, among other things, the valve and drier operating device, the vibration elimination feature, the drier clutch, the clutch control, the drier drive, and the drain board. The novel features and characteristics of the agitating device were originally claimed in my c opending application Serial No. 86,522 but were withdrawn from that particular application following a requirement for division.

What I claim is:

1. In apparatus comprising a pair of waterretaining chambers, a motor,` a pump driven by said motor, means connecting said pump with each of said chambers, valve means for closing the connection between said pump and said chambers alternately, washing means in one of said chambers and drying means in the other of said chambers, the combination of separate control means for connecting said washing means and said drying means to said motor to be driven thereby, and an interlocking connection between the valve means operating said valve means to open the connection between said pump and the chamber having said drying means and simultaneously closing the connection between said pump and said chamber having said washing means whenever said drying means is connected to said motor to be driven thereby. I

2. In apparatus comprising a pair of waterretaining chambers, a motor, a pump driven by the motor, and iluid conduits and drying control means for 1 said motor, means connecting said pump with each of said chambers, a valve housing having a port communicating with each of said chambers, valve means in said housing for selectively closing one or the other oi' said ports, and drying means in one of said chambers, the combination of control means for connecting said drying means to said motor to be driven thereby, and means interconnected with said control means for moving said valve means to open the port communicating with said one chamber and to close the port communicating with the other chamber when said drying means is operating.

3. In apparatus comprising a plurality of water retaining chambers, mechanical operating means in each of said chambers, a single motor arranged to drive each of said mechanical means, a pump arranged to be continuously driven by between the pump and each of thechambers, the combination of means for controlling the operation of each of said mechanical means', a valve arranged to connect the pump alternatively with one of the chambers and simultaneously close the connection to the other of said chambers, and an interlocking connection between the valve and control means arranged to prevent an open connection between the pump and one of said chambers when the mechanical means in the other chamber is in operation.

4. In apparatus comprising a plurality of water retaining chambers, mechanical operating means ineach of said chambers, a single motor arranged to drive each of said mechanical means, a pump arranged to be continuously driven by the motor, and fluidconduits between the pump and each of the chambers, the combination of means for controlling the operation of each of said mechanical means, a valve arranged to connect the pump alternatively with one of the chambers and simultaneously close the connection to the other of said chambers, an interlocking connection between the valve and control means arranged to prevent an open connection between ,the pump and one of said chambers when the mechanical means in the other chamber is in operation, and a. manual control for the valve permitting it to be operated before the interlock comes into play.
