Serial No. 90,197.

The invention relates to washing machines of that type in which the o erations of wash-' ing the clothes and centri ugal extraction of the liquid are successively performed in the same container. A serious difficulty encountered with this type of machine is due to lack of balance during centrifugation. It

is never possible to uniformly distribute the clothes in the container by the operation of the washing mechanism and therefore the revoluble container is initially out of balance. Furthermore, even if it were ossible to balance the container and its loa before centrifugation, it would lose its balance as an incident to the shifting of the' load and the removal of the liquid therefrom. Consequently such machines are never capable of being'revolved at a high rate of speed and the extraction of the liquid is very incomplete.

It is the primary object of the present invention'to obtain a construction which is highly eflicient in both the washing and ex? traction operations and to this end the invention consists in various features as hereinafter set forth. 4

My improved machine utilizes in part a principle of construction forming the sub ject matter of a prior Patent No. 1,L83,326,

issued February 12, 1924. This essentially is a means of automatically balancing a loaded receptacle during rotative acceleration thereof and comprises a universally rockable container mounted on a floating -support. In the present machine, however, the same receptacle is used for both washing and extracting operations and for the devised a machine 'of the following construction: I

Generally described my improved machine compris'es' a substantial cylindrical receptacle for receiving the articles to be washed and the washing fluid, said receptacle being providedwith a perforated lining slightly spaced from the outer imperforatewall to form a fluid passage therebetween. This receptacle is arrangedwithin an outer casing'which is mounted on the I pedestal or other. support and within which is arranged the motor. The axis "of this motor extends vertically. and one end of the I rotor shaft is connected through the medium of a slip clutch with an aligned .ver-

tical shaft extending upward centrally- The upper end of the shaft is connected by a universal joint with the receptacle to permit rocking movethe rapid rotation of the receptacle, is with-.

' wardly forated lining 7" ment thereof and there is also a second uni versal joint which ermits the rocking or ation of the shaft his latter movement is however opposed v by resilient means tending'to hold the shaft normally vertical'so that when the receptacle is revolved at a high rate of speed it is permitted to rotate about its true centre of mass or in d namic balance. Such rapld revolution wil centrifugally force any liquid in the receptacle radially outward through the perforated lining and upward between the same and the imperforate outer wall 'over the upper edge of the latter and into the outer casing from which it maybe discharged into a drain.

The washi'n'g is effected in the same re-v ceptacle by any suitable means for agi-' tating the contents thereof. Preferably this is accomplished by a single verticall reciprocating plunger which is actuated by a mechanism driven from the same motor. This plunger, when not in-useand during drawn into a recess in the cover and the actuatin mechanism is declutched. On the other and, when the plunger is in operation, the high speed drive connection between the motor and receptacle must be .de-' clutched, the cover for said receptacle closed and sealed to prevent the slopping. out of the liquid, andsupport afforded-to hold the receptacle from rocking and to take thethrust of theplunger. It is thereforenecessary to provide manu'ally operable control.

mechanism foreifectin these various adjustments together witfi safety appliances which. prevent adjustment dur ng. the rapid revolution of the receptacle, the detail .-'construction being asfollows:

1 is. a hollow pedestal supported at its lower end by the leg members 2 preferably provided with casters 3 and with feet 4' having threaded shanks 5 for adjusting the same so as to. take the weight from the casters. At the upper end of the pedestal 1 is an enlarged housing 6 within which is arranged hollow post 9 is a vertical ..rotaryshaft'10 provided at its upper end with a universal to the post preferably con pivotal couplin sisting of a s erical socket" member 11, a

ball 12 secure to the shaft 10 and an inter-- mediate rubber-lining" 11. 13 is a-hea'ded about a lowercentre.

shank having a threaded o'rtion for cla mp' ing the same to said s'oc etand-dependmg centrally therefrom into a tapering recess formed within the ball. The inner end 13" of this shank is of rectangular cross section and' segm'ental form to engage a similar rec- I tangular recess inthe centre of :the ball so" as to communicate a torque from one tov the other without interfering with freedom for universal rocking movement. The shaft 10 extends downward within the hollowpedestal 1 in axial alignment with the shaft 14 of an electric motor 15 mounted in the lower portion of saidpedestal. These shafts are 7 not however rigidly connected to each other but are coupled through-the medium of a1 slip clutch permitting the motor to gradually pick up the load. There is also rovided a universal coupling and resi 'ent.

means for yieldably resisting the rocking of one shaft with respect to the other.

omen p "Any suitable construction of slip clutch may be used but preferably it is constructed as follows: f

16 is .a disk having a central hub 16 which is pinned or otherwise rigidly connected withthe shaft 14. 17 is a housing periph: erally secured to. the disk 16 and extending upward therefrom. 18is a clutch member having a conical flange 18 surrounding and spaced from the hub of the disk 16. 19 are-- complementary brake shoes arranged within the space between the conical flange and the other by shanks 20 engagin housed in recesses within sai shoes. 19 are also connected through the me-- dium of swinging'links. -22 to the. di'sklfi,

flange 18. The clutch member 18 has a hola bushing 24 surrounding aportion of the .hubof the disk 16, and at the upper end of themernber. 18 is aflanged head 25. Thi .v

head is spaced from a parallel head '26 at the lower end of the shaft 10 and between 165 the arrangement being such that'upon' the rotation of said disk centrifugal forcewill' j tend to separate the shoesfrom each other and to press the same against the .conical v low shank member 23 slidably mounted on said. heads there is inserted a yieldable cush- 1 ion 27 preferably formediof rubber-.JrThe.

eus'hion'is flanged 'at itsupper and'lfower heads 25 and 26. Thus, t e

ends and the flanges are connected by (Eli s torque of theclut'ch member 18 will-be trans-5 mitted to the shaft 10 through the'lmedium of the-pantsmjust i e and at the same timefsaidzshaft .is free to oscillate. by th yielding of thecushi'on I madame hub. These are yieldably connected t'oeach springs 21 shoes. The

upper 'end of a hollow member 31 surrounding and spaced from thecushion member 27.

This member 31 is yieldably supported by a series of radial spring arms 31 non-symmetrically arranged about the same and connected at their outer ends through themedium of cushion members 32 with supporting spring arms 33 extending outward from the pedestal 1. The plane of the arms 33 is offset from the plane of the bearing so that any oscillation of the bearing 30 permitted by the flexing of these arms will be about a centre coinciding with that of the cushion member 27. Consequently the shaft 10 while normally held in alignment with the shaft 14 by the resiliency of the springs 31 and 33 and cushions 27 and 32 is nevertheless. permitted to move angularly so as to oscillate or gyrate about the centre of mass of the loaded receptacle 7. Thus, during the rapid revolution of the receptacle for the extraction operationas will be here inafter. setforth, the revolving partswill be in dynamic balance.

Plunger operating mechanism As has. been stated, I preferably agitate the clothes within the receptacle by a reciprocating plunger. This plunger 34 is hollow to surround the post 9 and the surrounding portion 35 is preferably of inverted conical form terminating in a depending flange 36: The top 37 of the surrounding portion of the plunger has the apertures 38 at its upper end to vent the chamber therein. Thus, when the plunger is vertically.

reeiprocated it will displace the clothes in the washin fluid within the receptacle 7 alternately in a radially outward and radially inwarddirection while the venting of the central chamber of the plunger avoids any tendency to suck the clothes into the same. The plunger is actuated by a vertically extending rod or tube 39 which is connected to an arm 40 mounted on a vertical rod or tube 41 arranged-at one side of i the housing 6. The rod 39 is also guided by passing througha bearing 42 in an arm 43 which extends from a tubular bearing 44 in which the rod 41 is slidably supported. The arm'43 also carries a cover 45 for the housing 6 which cover is so fashioned as to receivethe plunger 34 when drawn upward out of the" receptacle 7. The cover 45 is adapted to form a sealing .joint with the upper edge of the receptacle 7 preferably by being provided with the annular groove 46 for receiving the upper edge of said receptacle and having a gasket 47 therein for contacting the said edge. This arrangement will prevent any slopping over of the washing fluid during agitation of the same by The reciprocation of the rod 41 occurs only in certain positions ofadjustment of the clutched which is effected machine and is-efiected through the following mechanism. The motor 15 is provided with a downwardly extending rotor shaft 48 having a'worm 49thereon which meshes with the worm gear 50 on the horizontally extending shaft 51, these parts being enfurcated rock frame 57 havin'g arms 58 ex-' tending on opposite sides of the pedestal 1 connected to each other at their outer ends and substantially inalignment with the axis of the tubular rod 41. 59 is a small flexible rod pivotally attached at its lower end to the arms 58 and extending upward within the tubular rod 41 being connected at its upper end by the pin 60170 the arm 40. The flexibility of this rod is suflicient to permit the oscillation of the arms 58 about the axis of the shaft 56 and to communicate to the tubular rod 41 a rectilinear movement in the bearing 44. In other words the flexing of the rod 59 within the tubular rod 41 compensates for the lateral deflection of the are through which the lower end of said rod passes. The rock frame 57 being sleeved upon the rock shaft 56, will not be directly actuatedthereby. There is, however, provision for coupling these parts to each other comprising a notched segment 62 preferably integral with the rock arm 55 and a dog 63 for engaging the notch of said segment and pivotally attached to the rearwa-rdly extending portion 64 of the rock .frame 57. An actuating arm 65 for the dog 63 is attached to the opposite end of a rock shaft 66 forming the pivots for said dog. This arm has a portion 67 bearing a ainst a spring 68 in a recess in the frame 5 the arrangement being such that the tension of this spring presses the dog 63 against the segment 62 to automatically effect engagement with the notchthereof. Under certain conditions, however, the arm 65'is depressed against the tension of the spring so as to disengage the dog from the notch and permit oscillation of the rock arm 65 without imparting any movement to the frame 57 and arms 58. Under such conditions no movement is imparted to the rods 41 and 37 or to the plunger 34 carried thereby so that the receptacle 7 may be spun through the high'speed connection to the shaft 10. On

- the other hand, when the plunger is to be operated, the driving connection between the motor and the shaft 10 must be dearranged a bifurcated rock arm 69 mounted v by the following on a rock shaft 70 journaled (mite asta.

iSwfetg I wppldmaea I To avoid danger of accidents I have provided anumber of safety devlces for controlling the operation of the ad usting ;mechani sm particularly where the machine is runnin at high'speed, the-construction beingas ollows: Y

To prevent opening the machine dunng the rapid rotation of the rece tacle 7, there is a centrifugally operated 10c This comprises a ring, 94 surrounding the cushion 27 and within the hollow member 31 being slidabl mounted on bearings 94 on the flange member- 25"which hold it in concentric relation to theaxis of the shaft but permit axial movement thereof. 95 are pivotal arms mounted on the member 25 and arran ed to be thrown outward centrifufially, said arms being connected to latera .7 4 ring 94 to move the same upward. 97 1s a whic is extending pins 96 which engage "the I passin central] through the shaft. 73

Thus, it will be impossible to turn the hand wheel 74 to adjust any of the controls while the cover is removed from the receptacle 7. Furthermore, the operation of the lever 98 and rod 97 is rendered impossible during the rapid rotation of the receptacle by the ring 94 previously described in cooperation with the finger. 102 which is held from movement by said ring in raised position thereof. This finger 102 is connected to a forked arm 103 engaging a collar 104 slidable on the shaft 73 but connected through a pin 105 passing through a slot in said shaft to the rod 97. Thus, whenever the rotation of the shaft 10 is at suflicient speedto centrifugally operate the arms 95, the ring 94 will be lifted into interfering position with the finger 102 which,- through the parts just described, will hold the rod 97 from movement thereby preventing disengaging of the flanged head 99 from the flange 100. In this position of the parts only a limited rotation of the hand wheel 74 and shaft 73 is possible, this being per imtted by a cut away segment 99 in the member 99.

To load the machine for washing, the

- hand wheel 74 is first turned to the position where the index is opposite the position Stop on the indicator segment. This will turn the flanged head 99 into a position where a slot 99 in the flange thereof registers with the flange .100 of the member 101' thereby permitting said member to be rotated. The cam 88 has meanwhile actuated the arm-89, rock shaft 90 and rock arm 91 to lift the bearing 44, which, byralsing the arm' 43, lifts the cover so as to clear the receptacle 7 and housing 6. Thus, the operator is permitted to swing the arm 43 carrying the cover out of registratlon with the top of the receptacle and permitting the introduction of the clothes to be washed and the washing fluid. The operator then returns the cover into registration with the receptacle and adjusts the wheel 74 into the position "designated by the indicator as Wash. This first turns the flanged head 99 so as to lock the flange 100, thereby holding the member 101 and bearing 44' from rotation. Also the cam 88 1s turned to a position to lower the cover 45 engaging thegroove 46 thereof with the upper edge of the receptacle 7 and pressing the latter against the gasket 47 to produce a seal. A further movement resulting from the adjustment -of the wheel 74 to the wash position is the movement of the cams 77 and 78 so as to release pressure upon the corresponding plungers 81 and 85 which are raised bytheir respective springs 82 and 86. The lifting of the first of these I plungers frees'the rock frame 57 permitting the movement of the same together with the arms 58 attached thereto. The lifting of the plunger 85 frees the arm 65 and permits the spring 68 to press the dog 63 against the notched segment 62. Thus, in the first reciprocation of the rock arm 55 the dog will engage the notch coupling the rock frame '57 to said rock arm. One other movement effected by the last mentioned adjustment of the wheel 74 is the turning of the'cam 87 so as to actuate the arm 71, rock shaft and brake arm 69 pressing the latter upward against the flange 25 and moving the clutch member 18 to released position.

Washing operation The operator next turns the electric switch (not shown) for starting the motor 15 which through the medium of the shaft 48 and worm gearing 50 actuates the crank 53 and pitman rod 54 to impart a rocking movement to the arm 55. .This will reciprocate the, rock frame 57 and arm 58 attached thereto, raising and lowering the rods 59 and 41 and imparting a similar reciprocating movement to the rod 39 and plunger 34. Inasmuch, however, as the clothes in the receptacle may interfere with the full recip rocating movement of the plunger, a yielding element is placed in this drive connection. Preferably this element is the pitman 54 which, as shown, is formed with a telescopic rod 54*" and a spring 54 for yieldably fins 7 d on the bottom of the receptacle which cause a slow rotation of the mass within said receptacle. moved radially inward and outward and the fluid displaced by the downward movement The clothes are also alternately .1

of the plunger is directed inward by the inclined flange 7 Discharge of liquid At the completion of the washing operation the operator turnsthe hand wheel 74 to the indicated position Flood. tuates the cam 88 which throughthe mechanism previously described raises the cover. 45 to free'the upper edge of the receptacle This ac- 7 while still closing the aperture in the outer casing 6. As the plunger 34 continues its reciprocation the liquid will be displaced,

the floating scum thereon being forced out ward through the aperture 7 inthe flange with" liquid passin 1 through the perforated lining,will esca yso pressed out of contact with the overthe upper edge of the receptacle 7 into the casing 6 from which it asses-to the drain. 6. To complete the ischarge the hand wheel may be adjusted to the position d which'first depresses .the plungers 81- an 85 to raise the lunger 34 into the cover 45 and to declutc the dog 63 from the notched segment 62. The arm 69 is also deange 25 permitting the clutch'member 18 to engage with the cooperating clutch members and to impart a gradual rotative acceleration for the shaftand receptacle 7. This is continued until all of the liquid is thrown out centrifugally over thetop of the receptacle'7.

' Rineing o peration When all'of the liquid is thus discharged the operator again turns the hand wheel 74 to the indicated position Stop. ,This first lifts the arm 69 and-applies the brake to the revolving flange -and after the speed of the f rotating receptacle is sufliciently checked to lowerthe ring 94 out of the path of the finger 102 the lever 98 maybe operated'to unlock the flange 99 from the flange This permits the cover which has meanwhile been lifted out of engagement with the casing ,6 to be swung out of registration ,with the receptacle so that the I I l latter may be filled with rinsing water. The

cover is'then replaced and the hand wheel adjusted toythe position Wash which causes the plunger to agitate the clothes. Adjustment is thenmade successivel to the I positions Flood and Dry. to disp ace and ficient length of time to tfractionv of" li li-Lcondition for .found that five 'I-=.'

When, however, the motoris rotating at full speed, centrifugal force will overcome the resistance of the springs 21 and press the shoes-outward against said flange tending therewith. s this would overload the motor the eflect'actually produced is to slowthe speed of rotation to a point where the Y springs-to some extent balance centrifugal action and thereby limit the pressure of the shoes against the flange 18. This in turn will reduce the torque so that a balance is established where the pressure of the shoes is just suflicientto transmit the maximum e within the power of the niotdr The is thus gradually picked uprand the driven shaft is'gradually accelerated until its speed of rotation approximates that of .the driver. This will permit a higher speed to the driver which will increase the centrifugal ,action upon the shoes 19 finall causing them to positively lock with the flange 18 and to 'revolve all speed. 4 i It is obvious that with my improved construction of machine many 0 erations necessary with other machines are eliminated, for

instance, with machines having a separate wringer each separate articlemust, be handled, firstwhen placed in the washer, second 'machines heretofore" used the clothes remained in the same receptacle during washing and while they were subjected to cenclothes sufliciently for ironing, because of a laced on the line and removed therefrom. .ith my machine, after the clothes have been first introduced into the receptacle no parts at full the extra'cton It is thus necessary tohandle each article again when I a sufliciently dry. conif unrestrained, will build to form a locking engagement trifugation, it was impossible to 1 dry the v apidly revolving receptacle, will rotate about an axifsthat to the rapid revolution balancing mechanism for it is obvious that of a receptacle for containing both the pressure on the side of the receptacle farthest from the geometrical axis will be greater than that on the side nearer to the axis and this will tend to displace the receptacle from its proper position of balance.

I therefore preferablyv provide means for equalizing. this differential pressure which, as shown in Figures 12 and 13, is as follows: In the space within the outer casing 6 beneath the receptacle 7 I arrange a series of radial blades l'OG. As a result, instead of building up zones of pressure there is es tablished an. internal circulation, the air which is thrown out centrifugally returning through the static zone at the bottom of the casing and then again being thrown outward. By properly fashioning the plates 106 and inclining the same to the radius, any desired equalizing effect may be obtained and without obstructing the circulation of the air in such a manner as to interfere with the free rotation of the receptacle.

In addition to the function of equalizing the pressure in zones concentric with the axis but of different radius, the construction is one which prevents air loading. Such air loading would occur if the receptacle were to be revolved in the open as air would be drawn in adjacent to the axis and thrown off centrifugally. However, with the construction as shown, the cover 45 obstructs the passage of air axially into the receptacle from the top and the outer housing performs a like function at the bottom. This relieves the motor from unnecessary work and permits of revolving the container at a higher rate of s eed. 4 v
