This invention relates to a combinedclothes washer' and centrifugal drier involving the use of juxtaposed upright containers mounted upon a single supporting frame and containing the washing and drying mechanisms respectively adapted to be driven from the same source of power which is mounted upon the frame preferably in a plane directly beneath the containers. f

The main object is to provide a compact washer and drier of the type as a unitary article of manufacture vin which both of the mechanisms may be operated simultaneously or separately from the same source of power so that one batch of clothes may be operated upon by. the washing mechanism while a previously washed batch may be operated upon by the centrifugal drier thereby greatly increasing the output without extra work and permitting the clothes to be more convenient- `ly and directly transferred from one mechanism to the other without material loss of time or labor.

Another object is to reduce to a minimum the vibration of the machine incidental to the operation of the centrifugal drier particularly when rotated at the necessary high speed.

Another object isvto provide means whereby the washing Huid may be transferred from i either container to the as may be required washing and dryits drying element.

Other objects and uses relating to specific parts of the device will be brought out in the following description.

vAs illustrated, this machine comprises a main supporting frame of the tripod type having a substantiallyhorizontal platform 1 carried by a plurality of, in this instance, three legs 2 which are arranged at the angles of an isosceles triangle and in addition to being secured to the platform 1 by bolts 3 are also connected to each other some distance below the platform by braces 4 and 4 extending along the sides of the triangle and having their ends secured to the legs by bolts 5.

The lower ends of the legs are provided with castors 2 adapted to rest upon the ioor to permit the machine as a whole to be sof moved from place to place along the floor as may be more convenient for the operator as, for example, when using the machinesl in connection with stationary laundry trays in a manner hereinafter described.

The platform 1 is of sufficient horizontal area within its marginal edge to receive and support a relatively large circular washing vat or tub 6 and a relatively small circularv drier vat or tub 7 side by side in fixed relation to each other with the larger vat nearest the base of the triangle and the smaller vat nearer the apex of-the triangle and the axesv of both vats in a vertical plane lbi-secting the angle at the apex of the triangle and thereb passing through the base of the triangle mi way between the adjacent angles.

The vertical axes of the vats wholly within the triangle at the base of the triangle 6 and 7 are so that the angles will lie in vertical planes substantially co-incident with the ad-v jacent sides ofthe vat 6 and at equal distances'from the axis thereof while the angle at the apex of the triangle willbe in a vertical plane substantially coincident with the corresponding side of the periphery of the vat 7 and therefore the legs 2 which are s e-S cured to the angles of the triangular bracing frame may be substantially straight verticall and secured to the adjacentv portions of tlie peri heries of the vats 6 and 7 and also to the a jacent portions of the perimeter of the platform 1 which follows closely the circularoutlines of both vats.

The object of this triangular supporting and bracing means for the combined washer and drier isl to bring all of the mechanism to be brought into a unitary structure supported on the iloorat three bearing points for stabilizing purposes .and also to reduce to a minimum any vibration incidental to the joint or independent operation of both the washing and drying mechanism or either of said mechanisms separately as will be hereinafter more fully explained, it being understood that the platform 1 serves as a rigid tie connection between the two vats 6 and 7 to hold them against relative movement and in differentiating the drying mechanism from the washing mechanism. it will be observed that the distinction is only nominal, thewashing mechanism being .employed to loosen the dirt and other foreign matter from the clothes by alternate ressure and suction while the .centrifugal drying mechanism serves the double purpose of freeing the dirt -K and other foreign matter 1n solution from the clothes and also for drying the clothes, so that thellattermay reasonably be termed a supplemental washer as well as a drier.

Washing 'nwchm'sm In additionto the anism comprises a vat 6 the washing mechlurality of, in this instance, two inverte -cup shaped. dashers or mounte cups 8 operatively connected to a yoke 9 which in turn is adjustably mounted on a vertically mounted plunger 10, the latte-r being reciprocally movable in a suitable gland 11 Iin the bottom ofthe vat 6 coaxial therewith while the cups 8 are mounted upon the yoke 9 at one side of said axis for engagement with the clothes and washing fluid in the vat as the plunger and cups are reciprocated vertically.- i

Any suitable means may be employed for imparting vertical reciprocatory motion and also rotary motion to the upright shaft or plunger 10, said means being partially shown in the drawings as consisting of an electric motor 12 secured to the underside of the plat-- form 1 and having its armature shaft 13 connected by a universal joint 14 to a coaxial shaft 15 which is journaled in a suitable gear case 16 on the underside of the platform 1, said shafts 13 and 15 being located at one side of the axis of the vat 6 and parallel with a direct line between the axes of both of the vats 6 and 7.

A inion 17 is secured to the driving shaft 15 within the gear case 16 and meshes with a gear 18 which is secured to the hub ofa second cpinion 19, the latter being loosely upon a counter shaft 20 so as to permit the gear and pinion to rotate relatively 'to said shaft for a purpose presently ldescribed.

The pinion 19 meshes with a relatively large gear 21 which is loosely mounted upon a crankshaft 22 for relative rotary movement and also has an independent axial movement into and out of clutching engagement with a clutch member 23 having an elongated hub journaled in a bearing .24 in the adjacent end of the gear case 16 and carrying at its outer end a crank arm 25,.

The hub of the clutch member 23 together with the cra-nk arm 25 are keyed to eachother and to the shaft 22 by means of a key or pin 26, Figure 6, to cause those parts to rotate mvumson.

The crank arm 25 is operatively connected in any well known manner to the intermediate portion of a rock arm or lever 27 extending radially to and at one side of the axis of the vat 6 below the platform 1 and having one end pivotally connected at 28 to the outer lill exge of the platform and its inner end snita y connected to the lower end of the plunger 10 whereby as the shaft 22 with the crank arm25 thereon is rotated through the medium of the gear -train and clutch previously de'-l scrihed rocking motion will be imparted to the rock arm or lever 27 for reciprocating the Y pluger 10 and thereby effecting a corresponding reciprocatory movement of the yoke 9 and cups 8 carried thereb A coiled spring 29 may well known manner to the lever 27 and to the frame of the machine for retracting the inner be connected in any mitting axial motion to the clutch gaging said gear clutch with the end of the lever and upwardly and thereby lifting those parts. v

The counter shaft 2O is located between the axes of the vats 6 and `7 and approximately in a direct line between said axes while the driving shaft and crank shaft 22 are located at opposite sides ofand parallel with the counter shaft and therefore at opposite sides of the vertical axis of the vat 6 and plunger 10 while the motor 12 and gear case 16 containing the gear train connections between the drivingshaft 15 and lever 27 are also located at opposite sides of the lever 27 and plunger 10 so that the load incidental to the operation of the cups 8 for washing purposes is nearly in the center of the power pla-nt 011 the underside of the platform 1 for the purpose of distributing the power transmitting mechanism more evenly aro-und the plunger and thereby introducing a more effective balance andv consequent reduction of vibration in the operation of the washing mechanism.

As previously stated the clutch gear 21 is movable axially into and out of clutching engagement with the clutch member 2.3 and for this purpose is provided with apertures -30 adapted to receive studs -31 on the member 23 when the two parts are brought together for transmitting motion from the pinion 19 to the crank shaft 22.

The hub .of the clutch gear 21 is provided with an annular groove 32 for receiving a shifting member 33 which is connected to one end of a shifting rod 34, Figure 67 said split rod being mounted in a suitable bearing in the adjacent side of the gear case 16l and having its outer end connected to o ne end of a shifting lever 35.

This lever 35 is pivoted at 36 to the gear case 16 and has its other end connected by a link 37 to a crank arm 38 on the lower end of an upright tubular shaft 39, Figure 2.

The tubular upright shaft 39y extends upwardly along the outside of.and in close proximity to the vat 7 and has its lower end journaled in a suitable gearing 40 on the platform 1 and itsfalpper end provided with a hand lever 41 secured thereto for rocking said shaft about its axis and thereby transgeai 21 through the medium of the link 37, lever 35 and shifting rod 34 for engaging and disenclutch memparts carried thereby assisting the motor in It is now evident that while the motor 12 is in operation positive motion will be transmitted to the gear clutch 21 and that if the hand lever 4l is shifted in one direction the clutch gear 21 will be forced into engagement for operating the crank sha-ft 22 and thereby reciprocating the plunger 10 with the cups 8 thereon for wash-ing purposes while on the other hand if the hand lever 41 is shifted in i @entri/@Loyal drier An upright cylindrical cage 42 is rotatably mounted within the vat 7 coaxial therewith but clear from the walls thereof to avoid friction therewith and comprises a perforated bell 43 having its lower end secured to a circular supporting plate or bottom 44 and its upper end provided with a concave-convex cap or lid 45 removably mounted thereon but frictionally engaged therewith to be rotated thereby in a manner hereinafter described.

T he counter sha ft 20 is connected by auniversal joint 46 to an axial extension shaft 20 which is journaled in one side of a gear case 47 and is operatively connected by a beveled gear 48 and pinion 4Sto an upright shaft 50 which is journaled in a suitable gland 51 in the platform l coaxial with the axis of the cage 42 and has its opposite end provided with a hexagonal or other angular head 52 engaging in a similarly formed angular recess 53 in the bottom plate 44 for transmitting rotary motion from said upright shaft 50 to the cage 42 and permitting said cage to be removed from the head 52 by upward displacement when desired.

The gear case 47 is secured to the underside of the platform 1 as shown in Figure 4 andis provided in its lower side with an adjustable end thrust bearing screw 54 for the lower end of the upright shaft 50 and thereby to hold the rotary head 52 out of frictional engagement with the upper end of the gland 51 which is preferably of the stufing box type to prevent leakage of water from the bottom of the vat 7 through the gland.

Suitable means is provided for controlling the operation of the centrifugal drier mechanism independently of the washing mechanism while the motor is in operation and as previously stated the gear 18 which is driven continuously by the motor through the medium of the pinion 17 is loosely mounted upon the shaft 2O to rotate independently thereof and is provided with a conical clutch face adapted to be engaged by a conical clutch member 56 on one end of a brake drum 57 which is splined on the shaft 2O for axial movement and is spring-pressed in one direction by a coiled spring 58 for frictionally engaging the vclutch member 56 with the clutch gear 18 for transmitting motion to said shaft 20 and thence through the shaft 20 and gears 48 and 48 to the upright shaft 50 for rotating the cage 42, the clutchmember 56 being riveted or otherwise secured to the hub of the brake drum 57 as shown in Figure 4. i

The brake drum 57 is provided with an `outwardly projecting annular flange having a friction washer 57 of fibre or equivalent material adapted to be engaged by a brake shoe 59l constituting a part of the clutch shifting means.

An upright rock shaft is journaled in suitable bearings in the gear case 16, Figure 6, and has its lower end provided with a crank arm 61 pivotally connected at 62 to the brake ring 59 and its upper end provided with a crank arm 63 connected by a'link 64 to a crank arm on the lower end of an upright rock shaft G6 which extends vertically lthrough the tubular shaft 39 coaxial therewith and has its upper end journaled in the adjacent side of frame 67 and is provided with a hand lever 68 by which it may be turned for shifting the clutch member 56 into and out of clutching engagement with the clutch gear 18 and also yfor moving the brake ring 59 into andout of engagement with the friction face 57 of the brake drum 57.

The frame 67 embraces a portion of the periphery of the upper end of the washing vat 6 and may be rigidly secured thereto by brazing or other suitable lfastening means and extends entirely around the upper end of the drier vat 7 to which it may be also rigidly secured by brazing or otherwise to form a rigid tie between the upper ends of both vats forvholding them in fixed relation, said frame being provided with a central cylindrical opening 69 of' sufficiently large diameter to permit the Acage .42 to be withdrawn therethrough by upward displacement when desired er Areplaced' by downward displacement into interlocking engagement -with the driving head 52.

A'lid or cover 70 for the opening 69 is hinged at one side at 71 to the frame 67 at a point beyond the adjacent side of the vat 7 and when closed is adapted to engage the upper inner faces of the walls of the opening 69 to form a substantially water-tight joint therewith or it is held in place by a locking bolt 72 and spring 73, both guided in a bushingv 74 in the adjacent side f the frame 67, the outer end of the bolt being provided with 9.a handle 75 by which it may be Withdrawn from its locking position against the action of its retracting spring 73, Figure 3.

The lid is also concave-convex in cross sectionv and is provided at the side nearest which it may be opened and closed.

The lever 68 which controls the operation of the centrifugal drier cage 42 is provided with an extension 68 movable into and out o f engagement with theupper facev of the adjacent side of the lid 70 for locking said lid in its closed position when the lever 68 is adjusted to cause the rotation of the cage 42 and to release said ld when the lever is G5 adjusted to stop the operation of the cage,

but the lid 70 cannot be raised until it is further unlocked bythe withdrawal ofthe j bolt 72 thereby reducing the liability of openrotation of the cage it will be necessary to withdraw the bolt 72 to release the lid 70 and permit it to be opened.

The cap 45 covering the upper open end of the cage 42 is centrally journaled by antifriction bearings 7 6 upon a suitable supporting stud 77 on the underside of the lid 70 so that when frictionally engaged with the upper end of the cage-it will rotate freely therewith and will also serve to hold the cage against excessive vibration in case the clothes therein should be slightly heavier on one side than on the other while the cage is being rotated at high speed.

The upright perforated walls of the cage 42 are arranged in sufficiently spaced relation te the inclosing walls of the vat 7 to permit the washing or rinsing fluid to be thrown by centrifugal force from the clothes through the perforated side walls of the cage and into the surrounding portions of the vat as the cage is rotated, the gear ratio of the driving mechanism for the cage being such as to rotate said cage at a sufficiently high s eed to expel practically all of the moisture rom the clothes by centrifugal force so thatafter a comparatively brief period of operation the clothes are practically dry and more or less fluffy ready for smoothing by a suitableY ironing mechanism.

Suitable means is also provided for assistcircumferential series of vanes or ribs 8() extending outwardly from the center thereof and preferably onthe upper face of the cover 45 and arranged so as to create circulation of air from the top downwardly through the openings 78 and 79 and thence through the clothes in the revolving cage and out through the perforations in the side walls of said cage into the outer container from which it is drawn into and through the pump, it being understood that during such rotation the clothes arethrown with considerable force from perforated walls of the cage leaving more or less air space in and around the axis of the cage and permitting circulation of air therethrou h leaving. the yclothes in a substantially ry fluffy condition. Y

It will be observed upon reference to Fi ure 4 that the brake shoe 59 operates direct y against the brake surface 57 of thebrake drum 57 yto disengage the clutch member 56 1 the center and against the from the clutch gear 18 against the action of the retracting spring 58 which serves to retract both the clutch member 56 and brake drum 57 under which conditions the application of the brake simultaneously with the withdrawal of the clutch member 56 will retard and stop the rotation of the shafts 2O and 20 and cage 42 driven thereby, all of which greatly expedites the centrifugal drying operation and enables both the brake and clutch to be controlled by the same lever 68 which is coaxial with and in proximity to the Washer controlling lever 41` as shown in Figure 2 thus permitting both levers to be operated from the same side of the machine.

This proximate coaxial operation of the two levers 41 and 68 also permits the use of coaxial detents 81 and an interposed coiled spring 82 arranged with a socket in the adjacent portion of the frame 67 for engaging in recesses in the adjacent faces ofthe levers 41 and 68 to frictionally hold them in their different positions of adjustment` the shaft 66 and lever 68 carried thereby having slightly vertical movement against the action of a retracting spring 83 between the hubs of the crank arms 38 and 65 to adjust the engagement of the. extension 68 with the upper face of the lid when the latter is closed and also to assist in frictionally holding the shaft 66'and tubular shaft 39 against accidental displacement from their adjusted positions.

i Fluid circulating mechanism Suitable means is provided for withdrawing the washing or rinsing fluid 'from both of the vats 6 and 7 and also for transferring the suds or other fluid from the drier vat to the washing vat and for these purposes the bottom of the Washing vat 6 is provided with an outlet nipple 84 to which is connected one end of a valve case 85 having its other end connected by a conduit 86 to the inlet side 87 of a rotary pump 88, the latter having its impeller 88 upon the driven shaft 15, the pump casing forming, in this instance, a part of the gear case A16 as shown more clearly in Figures 6 and 8.

The conduit 86 is connected by a branch 89 to an opening 90 in the bottom of the drier vat 7 to form a liquid tight joint therewith thereby establishing open communication between the interior of the drier vat 7 and inlet 87 of the pump 88, see Figures 6 and 13.

The inlet opening of the valve case 85 is controlled by a valve 91 which is yieldingly mounted upon a crank arm 92 of a rock shaft 93, the latter being journaled in one side of the valve case 85 and provided with an external hand lever 94 by which the valve may be opened and closed at will as maybe remounted directly v quired to retain or to discharge the water in and from the vat 6.

The outlet side of the pump 8 is connected by a. conduit 95 and'nipple 95 to a valve chamber 96 in the frame 67, said valve chamber having branch openings 97 and 97. leadfrom opposite sides thereof and controlled by a hollow valve 98 having -an external operating member 98 and a radial opening 99 which may be brought into registration with one or the otherof the branch passages 97 or 97 to vary the direction fof low of water from the valve chamber.

The branch passage 97 is connected by an elbow 100 to an inlet opening in one side of the washing vat 6 near the upper end thereof While the branch passage 97 is connected to a discharge nozzle 101 adapted to discharge over a water table 102 intoV a stationary laundry tray A or other receptacle.

.In Figures 6 and l1 the valve 98 is adjusted to divert the water from the pump into the -nozzle 101 but by turning it onehalf turn the opening 99 may be registered with the branch 97 to divert the water from the pump back into the washing vat 6.

The drain board 102 extends under the adjacent end of the frame 67 at the side of the vat 7 opposite the vat 6 and is preferably hinged at 104 to said frame andv provided with opposite concentric slots 105 for receiving clamping bolts106, Figure `1, by which the drain board may be tilted to different angles to or from a horizontal plane and locked in any position of adjustment as may be required to direct the water discharged from the nozzle 101 into a suitable receptacle as the vat A.

Operation The clothes to be washed together with a suitable washing Huid forming what may be termed suds, is placed in the vat 6 beneath the cups 8 under which conditions the valve 91 will, of course, be closedIl to retain the washing iuid in the vat. Y

The electric motor 12 is then started by the operation of any suitable controlling switch thereby operating the pump 88, gear 18, its pinion 19 and gear 21. l

Throwing the clutch Agear 21 into engagement with the clutch member 23 will cause the operation of the lever 27 and plunger 10 carrying the cups 8 for washing the clothesA in the vat by alternate pressure and suction as the cups are reciprocated vertically into and out of engagement with the clothes.

As soon as the clothes are properly washed in the vat 6 they may be withdrawn therev from by hand across the frame67 and into the cage 42 which has been previously opened los for such purpose by opening the lid`70 carly washed clothes are placed Within the revoluble cage 42 substantially filling the same, the lid 70 with the cover plate 45 thereon is closed and locked in its closed positionwith the cover plate 45 frictionally engaged with the upper edge of the cage 42 to rotate therewith, it being understood that the lid 70 will then be firmly held against rotary movement.

The lever 68 and its rock shaft 66 are then turned in the proper direction for releasing the brake shoe 59 and simultaneously engaging the clutch 56 with tlieclutch gear 18 for transmitting rotary motion from said gear to the shaft 20 and thence through the shaft 20 and upward shaft 50 to the cage 42 which with the wet clothes therein is driven at relatively high speed to expel practically all of the moisture from the clothes through the perforated walls of the cage and into the vat 7. y

As previously stated the lower end of the Vat is in open communication with the inlet side of the pump 88 through the pipe 89 and owing to the continued operation -of the caf j receptacle" or waste out through the passage 97 and pump 88 the washing fluid accumulating in the vat 7 will be withdrawn therefrom and forced through the pipe 95 into theI valve chamber 96 and by adjusting the valve 98 to the position shown in Figures 6 and 11 the washing Huid withdrawn from the vat 7 will be forced outwardly through the passage 97 and nozzle 101 Vinto one or the other of the laundry trays A or into any other suitable pipe.

Or, if it is desired to withdraw the washing fluid from the vat 6 it may be accomplished by simpl opening the valve 91 and allowing the lui in the vat to pass through the conduit 86 into the inlet side of the pump 88 from which it will be expelled through the pipe 95 into the valve chamber and thence nozzle 101.

On the other hand, assuming that it is desired to return the suds water accumulating in the vat 7 and that the valve 91 is closed, the valve 98 may be reversed to cut off communicationl between the conduit 95 and branch 97 and to open communication between said conduit and the branch 97 thus rniitting the water to be thrown directly om the -drying vat 7 and'discharged into the upper portion of the washing vat 6 thus permitting the re-use of the same suds as long as may e desired without varying the amount of water in the washing vat and at vthe same time maintaining a continuous withdrawal of the uid from the clothes in the d ing vat.-

t will be evident from the foregoing descri tion that as soon as the previously was ed clothes have been transferred from the. washing vat 6 to the drier cage 42 and durin the lcentrifu al drying operation an additional batch o soiled c othes may be placed iii the .washing vat and operated upon by the washing mechanism without disturbing the operation of the drier cage, all of which greatly increases the output of the machinel and insures a complete washing and drying" of the clothes with the expenditure of a minimum amount of labor and expense and without liability of injuring the finest of fabrics or mutilation of any parts thereof and at the same time permitting either mechanism to be operated independently of the other or simultaneously as may be required.
