As illustrated, this machine comprises a main supporting frame of the tripod type having a substantiall horizontal platform 1 carried by a p urality of, vin lthis instance', three le s 2- which are arran ed at the angles o an isosceles triangle an 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 havingv 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 iioor to permit the machine as a whole to be moved from place to place along the'iioor as may be more convenient for the operator as, for example, when using the machines in connection with stationary laundry trays in a manner. hereinafter described. v
The platform 1 is ofsuiiicient horizontal area .within its marginal edge to re-` ceive and support a relatively large circular vat or tub 6 and a relatively small clrcular drier vat or tub 7 side by side in fixed relation to each other with the er vat nearest the base of the triangle the" smaller vat nearer the apex of the izo fia
" :triangle and the axes of both vats in a vertical-plane bisecting the angle at the apex of the triangle and thereby passing throu h the base of the triangle midway between the adjacent angles.
The vertical axes of the' vats -6- and -7- are wholly within the triangle so that the angles at the base of the triangle will lie in vertical planes substantially coincident with the adjacent sides of the vat -6- and at equal distances from the axis thereof while the angle at the apex of the triangle will be in a verticalplane substantiall coincident with the corresponding side of t e periphery of the vat -7- and, therefore, the legs 2- which are secured to the angles of the triangular bracing frame may be substantially straight vertically and secured to the adjacent portions of the peripheries of the vats 6 and -7- and also to the adjacent portions of the perimeter of the platform l which follows closely the circular outlines of both vats.
The object of this triangular su porting and bracing means for the combined washer .and drier is to bring all of the mechanisms to be brought into a unitary structure supported on the door at 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 -i7 to. hold them against relative movement and in diierentiating the drying mechanism from the washing mechanism, it will be observed that the distinction is only nominal, the washing mechanism being employed to loosen the dirt and other foreign matter from the clothes by alternate pressure and suction while the centrifugal dryin mechanism serves the double purpose o freeing the dirt and other foreign matter in solution from the clothes and also for drying the clothes so that the latter may reasonably be termed a supplemental washer as well as a dried, Werking mechanism ln addition to the vat -6- the washing mechanism comprises a plurality of, in this instance, two inverted cup shaped dashers or cups A8-f operatively connected to a yoke 9 which, in turn, is adjustably mounted on a vertically mounted plunger -10-, the latter being reciproeably movable in a suitable gland l1 in the bottom of the vat 6 co-axial therewith while the cups ,-`8-' are mounted upon the yoke -9- at one side of said axisfor engagement with the clothes and washing fluid in the vat as the plunger and cups are Areciprocated vertically.
Any suitable means may be employed for imparting vertical reciprocatory motion and also rotary motion tothe upright shaft or plunger l0- said means being partially shown in the drawings as consisting of an electric motor l2- secured to the underside of the platform --land having its armature shaft -13- connected a universal joint -14- to a co-axial sha t -15- which is journaled in a suitable gear case -16- on the underside of the platform --1-, said shafts -13- and -15--4' being located at one side of the axis of the vat -6- and parallel with a direct line between ythe axes of both of the vats -6- and -7-.
ter shaft v-QO- so as to permit the ear and pinion to rotate relatively to said s aft for a purpose presently described.
rlhe pinion -19- meshes with a relatively large gear -21- which is loosely mounted upon a crank shaft 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 bearl ing -24- in the adjacent end of the gear case -16- and carrying at its outer'end a crank arm -25-.
rlhe hub of the clutch member -23- together with the crank arm -25- are keyed to each other and to Athe shaft -22- by means of a key or pin -26.-, Figure 6, to cause those parts to rotate in unison.
The crank arm 25- is operatively connected in any Vwell known manner to the intermediate portion of a rock arm-or leverl -27- extending radially to and at one side parted to the rock arm or lever +27- for reciprocating the plunger -10- and thereby effecting a corresponding reciprocatory movement, of the yoke -9- andcups 8- carried thereby. v
A coiled spring,29- may be connected in any well known manner to the lever 27 and to the frame ofthe machinefor retracting the inner end of the lever and parts carried thereby upwardly and'thereby assisting the motor in lifting those parts.` v The counter shaft '-20- is located beiso said axes while the driving. shaft and crank shaft -22- are located at opposite sides of and parallel with the counter shaft and, therefore, at opposite-sides of the vertical axis of the vat 6 and plunger l0- while ,the motor @l2- and gear case 16 containing the gear train connections between the driving shaft --15A and lever -27- are also located at opposite sides of studs 3lon clutching engagement with the clutch member-23- and for this purpose is provided with apertures the member -23- when the two parts are brought together for transmitvided with an annular groove -32- for-reting motion from the pinion -19- to the crank shaft 22.
The hub of the clutch gear -21- 1s proceiving a shifting member 33 which is connected to one end of a shifting rod -34,
Figure 6, said split rod being mounted in a suitablev bearing in the adjacent side of the gear case -16- and having its outer end connected to one end of a shifting 'lever This lever -35- is pivoted at 36 to the gear case -16- and has its other end connected by'a -38- on the lower end lof an upright tubular shaft -39-, Figure 2.
The tubular upright shaft-39eextends upwardly along the outside of and in close proximity to thevat -7- and has its lower end journaled in a suitable bearing "-40- on the platform 1-'- and its upper end provided with a hand lever #-41- secured thereto for rocking -said shaft about its axis and thereby transmitting axial motion. to the clutch gear V-21 through the medium of the link -37-, lever -35- and shifting rod -34-- for engaging and disengaging said gear clutch with the clutch member -23-.
It is now evident that while the motor l2- is in operation positive motion lwill be transmitted to the gear clutch -21 and that if the hand lever -41- is shifted in one dir ec-- tion the clutch gear 21ewill be forced into engagement for 'operating the crankshaft -22- and thereby reciprocating the plunger j l0- with the cups -8- thereon for washing purposes while on the other hand if the hand lever 4lis shifted in the opposite e tov stop the reciprocation o -30-' adapted to receive,
link w37- to a crank arm leakage of water from the bottom of the direction the clutch gear 21J will be withdrawn froml engagement with the member -23- to be operated independently thereof the plunger and parts carried thereby.
omfagaz amr I An upright c lindricalcage 42- is'rotatably mounte within the vat -7-1- coaxial therewith but clear from the walls thereof to avoid friction therewith and comprises a rforated shel1j-43- having its lower en se- A cured to a circular supporting plate or bot'- tom +44- and its upper end provided with f a concavoconvex lid -45-f removably mounted thereon, lbut frictionally engaged therewith to be rotated thereby in lav manner hereinafter described.
T he counter shaft *20- is connected by sion shaft.-20- which is journaled in' one connected by a beveled gear -48- and in- Aion -48- to an upri ht shaft -50- w ich is journaled in a sulta le gland-51, in the platform -1- coaxial with the axis of the cage 42- and has its opposite end provided with a hexagonal or other angular head -l-52- engaging in a similarly formed angu- -lar recess +53- in the bottom plate-44:- for transmitting rotary motion from said upright-shaft -50fto the cage42` and rmittng saidcage to be removed from the ead ,-52- by upward displacement lwhen desired.. j
The gear case [,-47- is secured to the un-y derside of the platform '-1- as shown in Figure 4 and is provided in its lower side with an adjustable and thrust bearingscrew -54 for the lower end of the upright shaft '-50-l and thereby to hold the rotary head 52 out of frict1ona1 engagement with the upper end of the gland -51- which is preferably of the stuing box type vto prevent vat side of a gear case'l-47- and is operatively 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 ofthe pinion-17-, is loosely mounted upon the shaft -20- to rotate independently ythereof and is provided with a conical clutch face 55.- adapted to be engaged by a conical clutch member -56- on one end of 20- and thencethrough the shaft -20` and gears and -48- to the upright -58- for frictionally engaging the vat -6- and may `by brazing or other suitable fastening means rigidly secured by brazin shaft 50 for rotating the cage -,-42', the clutch member -56- bein riveted or otherwise secured to the hub o the brake drum -57-, as shown in Figure 4.
The brake drum -.57- is rovided with an outwardly projecting annu ar iangejhaving a friction washer -57- of fibre or e uivalent material adapted `to be engaged y a gramas A tion of the centrifugal drier cage 4Z-'is provided with an extension 68 movable into and out of engagement with the upper face of the adjacent side of the lid 70` for lockingsaid lid in its closed position 4when the lever -68 is adjusted to cause the rotation ofthe cage 42- and to release said lid when the lever is adjusted to stop the opbrake shoe -59- constituting a part of the feration of the cage, but the lid -70-` cannot clutch shifting means. V
An upright rock shaft is j ournalled in suitable bearings in the gear case -16-, Figure 6,` and has its lower end provided with a crank arm Glpivotally connected at -62-to the brake ring -59- and its upper end ro-k vided with a crank arm -63 connecte by a link 64kto a crank arm -65- on the lower end of an upri ht rock shaft 6G- which extends vertical y through the tubular shaft -39- coaxial therewith and has its upper end journaled in the adjacent side of a frame -67--and is provided with a hand lever 68- by which it may be turned for shifting the clutchl member -56- into and out of clutching engagement with the clutch gear l8- and also for moving the brake ring 59 into and out of enga ement with the7friction face -57- of the -5 The frame -67-. embraces a ortion of the periphery of the upper end o the washing rigidly secured thereto ralre drum and extends entirely around lthe upper end of the drier vat -47--4to which it may be also or otherwise .to form a rigid tie between t e upper ends of both vats for holding them in fixed relation, said frame being provided with a central cylindrical opening -69- of sufficiently large diameter to permit the cage 42+ to be withdrawn therethrough by u ward displacement when desiredor re lace by downward displacement into inter ocking engagement with the drivin head -52-.
A lid or cover 0- for the opening -69- is hinged at one side at -71- to the frame -67- at a point beyond theadjacent side of the vat -.7- and when closed is adapted to engage the upper inner faces of the walls of the openinu -69- to form a substa-ntially water-tight joint therewith or it is held in place by a locking bolt -7Y2- and spring -73-, Aboth guided in a bushing 74- in ther adjacent side of the frame -67-, the outer end of the bolt being pro- Y vided with 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 70 is also concavo-convex in cross section and is provided at the side nearest ,the lookin bolt -72 with a handle The lever --68- which controls the operabe raised until it is further unlocked by the withdrawal of the bolt -72- thereby reducing the liability of opening thelid while the cage with the clothes therein is lbeing rotated,y it being understood that when the lever -68- is adjusted to stop the rota.- tion of the cage it will be necessary to withdraw the bolt -72- to release the lid 7G- andV permit it to be opened.4 j
The cap -45- covering the upper open end of the cage -42- is centrally journaled by anti-friction bearings --76- upon a suitable supportin stud.77- on the underside of the lid 0- so that when frictionally engaged with the upper end of the cage it will rotate freely therewith and vwill 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 to 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 10g and into the surrounding portions ofthe vat as the cage is rotated, the gear ratio of the driving mechanism for the ca e being such as to rotate said: cage at a s ciently high speed to expel practically all of the moisture 105 from the clothes by centrifugal force so that after a comparatively brief period of operation the clothes arepracticall dry and more or less iuify ready for smoot ing by a suitable ironing mechanism.
Suitable means is also provided for assisting this centrifugal drying of the clothes dur ing the rotation of the cage and for this purpose the lid .70- 'is provided with a circumferential series of o enings 7S- while 115 the cover plate -45- or the ca e -42- is(Y l also provided with openings 9 vthere- A through and a circumferential series of vanes or ribs -80- extending outwardly from the center thereof and preferably on the upper face of the cover 4 5- and arranged so as to create circul `tion of air from the top downwardly throug/li the openings -78'- and 79 and th/ence throu h the clothes in the revolving cage and out t rough the perforations in the side walls of said cagevinto the outer container from which it is drawn into andfthrough the pump, it being understood center and against the perforated walls. the] ure 4 that the brake` shoe -59- operates di` rectly against the brake surface -57- of the brake drum -.57- to disengage the clutch member -56- fromthe clutch gear '-18- agalnst 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 lclutch member -56- will retard and stop the rotation of the shafts -20- and -20 and 4cage 42- driven thereby, all of which greatly ex editesthe centrifugal drying operation an 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 Ashown 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 4land G9- also permits the use of coaxial detents 81e and an interposed coiled spring -.-82- arranged within a socket inthe adjacent portion of the frame.f67- for en 'aging in recesses in the adjacentfaces of the evers 4land G8- to frictionaly holdfthem in their different positions of a lustment, the shaft 66- and lever 6811- I 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 with4 the upper face of the lid --'70-` when the latter is closed and also to assist in frictionally holding the shaft -66- and tubular` shaft 139- against 4accidental displacement' from. their adjusted of the vats- -6- and 450 positions. e Flu/icl circulating Suitablemeans is provided for withdrawing the washing or rinsing uid from both -7 and also for transferring the 'suds or other fluidfrom the ldrier vat to the washing vat and for these purposes' the bottom of the washing vat -6- is provided with an ,outlet nipple S4- to whlch is connected one end ofa valve case S5- having its other end connected by a ing, in this instance, a lpart of the gear case- 16 as shown more clearly in Figures 6 and 7. The) conduitl 8G-'- is connected by a branch -89- to an opening -90-- 1n the *bottoml of the drier vat --7 to form a liquid tight joint therewith thereby establishing o en communication between the interior of t e .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 yieldlngly mounted upon a crank arm 92- of a rock shaft -93-, the latter being journaled fin'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 y will Ias may be required to retain or to discharge the water in and from the vat -.6-.
The outlet side of the pump -8- is'connected by conduit 95,- and nipple 95'- said valve chamber having branch openings -97and -97' leading from opposite sides thereof and controlled by a hollow valve -98- having an external operating member -98' and a radial opening -99- which maybe brought into registration with one or v the other of the branch passages -97- or 97?- to vary the direction offlow of water from the valve chamber. n
The branch passage Q7- 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 nozzlelOladapted to discharge over a water table 10Q-- into a stationary laundry tray -KA- or'other receptacle.
In Figures 6 and 11 the valve 4-98- is adjusted to divert the ywatersfrom the pump into the nozzle -10` 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 -101- into a suitable receptacle as the.
vat -A--L Operation The clothes to be washed together' with a suitable washing flui formingwhat may neath the cups '.-8- unfder which conditions the valve -91-fwill, f course, be closed to retain the washing Huid in the vat.
by the operation of any suitable controlling switch thereby operating the Vpump S8-,-
The electric motor L12- is then started.
toa valve chamber -96- in the frame -67-, I 80 be termed suds, is place iin the vat -6'- bei with the clothes.
Throwing the clutch gear -21 into engagement with the clutch member -23- will cause the operation of the lever -27- and plunger -10- carrying the cups -8- for washmg the clothes in the vat by alternate pressure 'and suction as the cups are reciprocated vertically into and out of engagement A Jrictionally engaged with the upper edge of the cage 42- to rotate therewith, it being understood that the lid 70 will then be rmly held against rotary movement. A
The lever '68- and its rock shaft 6G- are then turned in the proper direction for releasing the brake shoe -59- and simultaneously engaging the clutch 56- with the clutch gear -18- for transmitting rotary motion from said gear to the shaft 20- and thence through the shaft -20- and upward shaft 5G- to the cage 42- which with the wet clothes therein 1s driven atrela- `tively high speed to expel practically all of the moisture from the clothes through the perforted walls of the cage and into the vat c e As previously stated, the lower end of the vat is in open communication with the inlet side of the pump -88 through the pipe -l--S- and owing to the continued o eration ofthe pump -88- the washing uid accumulating in the vat -7- will be vwithdrawn therefrom and .forced through the pipe -95- into the valve chamber -96- and y adjusting the valve 98 to the position shown in Figures 6 and 1l the washin fluid ywithdrawn from the vat -7 will be orced outwardly through the passage -97 and laundry trays -A- or into any other suitable receptacle or waste pi e.
Or, if 1t is desired to withdraw the washing fluid from the vat -6- it may be accompllshed by simply o ening the valve -91- and allowing the uid in the vat topass through the conduit '-86- into the inlet Aside of the (pump '-88 from which it will be ex elle through the pipe -95- into the lva ve chamber and thence out through the 0n the other hand,assuming that it is desired to return the suds water accumulating in the vat -7- and that the valve-91-vis memes closed the .valve -98- may be reversed to cut off communication between the conduit -95- and branch -97- and to open communication between said conduit and the branch -97- thus permitting the water to be thrown directly from the drying vat -7- and discharged intovthe upper portion of the washing vat -6- thus permittinhe reuse ofthe same suds as long as may desired Without varying the amount of water in the washing vat and at the'same time maintaining a continuous withdrawal of the fluid from A the clothes in the drying vat.
1t will be evident from the foregoing description that as soon as the previously washed clothes have been transferred from the washing vat -6- to the drier cage 42- and during the centrifugal drying operation an additional batch of soiled clothes may be laced in the washing vat and o erated upon y the washing mechanism wit out disturbing the operation of the drier cage, all of which greatly increases the out ut of the ma- 1 chine and efects a complete was in and dry- -ing of the clothes with the eXpen iture 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 independentlyy of the other or simultaneously as may berequired'.
We claim: y 1. ln a high speed rotary extractor mechanism, a vat, a clothes container positioned in the vat, drivingmechanism below the vat for rotating the clothes container and including a clutch mechanism for making and breaking the driving connection, a rock shaft-extending vertically at one side of the vat and lconnected to said clutch mechanism lbelow the vat, a cover for the vat, a member secured to .the vertical shaft and turnin therewith 'as the clutch is moved to operative and inoperative position, said member being disposed in such relation with res ect to the rock shaft that it is moved over t e cover to revent opening of the cover when the clutch 1s moved in the operative position by rocking of said shaft and so that the member is disposed at one side'of the cover when the clutch member is moved to inoperative posi- 4tion by reverse rocking of said shaft, said member constituting a handle for rocking said shaft, and additional means actuated by the rocking of said shaft in the direction to render the clutch inoperative to rapidlyredu'ce the speed of rotation of the container.
