' lThe upper-baffles k3ft :are herein-shownV asinte-y gral parts offthet'op metalcasting-.96,A although they maybe separately attached thereto, or -to the tub, or constitute parts ofthe tub-body, and may be varied in number, two being shown, located at opposite sides ofthev tub. Theyl are of n-'likecharacter -rounded at the inner thinner edges .|56,'and each having a tapered side |51, merging gradually into the inner surface of.. the tubv body, whilefthe opposite side |58 ofeach baieis straight, presenting a flat, radially extending side. A`The fiat'sides of .the baffles 3d face in' thesame direction'with respect to the direction of tub oscillation, for a purpose to be referred tolater. The edges `|56 slope @downwardlyand inwardly from the casting 66,.sub stantially as chords of the cross sectional arc of the tubbody 79, tol a position closek to the mid channelr 92, where they are suddenly sloped into the tub surface. The broad sides of the bafes extend in a general radial directionto the tub axis at any horizontal section, but longitudinally, they slope relative tothe vertical atan angle vof about twenty-five degrees.

Thelower baiiles. 32, constituting parts of the agitator 83, are mounted on the disc-like base 84, from the center of which theyv extend radially. At the upper edge, the bafes are rounded, and the sidesrdivergingly tapered laterally tothe base. In vertical plane. outlineV the lbaffles are each of generally curved or rounded contour conforming somewhat to the lower recess of the tub, and having outer enlarged portions |63. These'baffles, in relation to such recess and to the globular rising sides of the outer portio-ns of the tub,v cause the water and clothes mass to be impelledradially outwardly and upwardly alongv the sides of the tub, which mass, if uninterrupted, would immediately move downwardly in the center of the tub, round and round. However, at the top, the clothes encounter the kagitation produced bythe upper baffles 34, y'which will break up thecycle produced bythe lower agitatorvand keepthe. clothes Well spread out, the Vover-all agitation being a combination o-f actions. y The baffles 34, by the lengths and the angular disposition thereof, tend to and do lift .the clothes alongthe baffles, and turn the clothes over, and are of greatest radial depthmidway of the length thereof, so that, as the tub oscillates onv its vertical axis,l the greatest force exerted upon the clothes is radially inwardly along and opposite lment is augmented by the fresh rinse water entering, the tub, in the direction Vof .the arrow .At thesame time, the vfreslivv'ater `is introduced and fmixed in definite and symmetrical mannen ensuring its diffusion to allparts ofzthelclothes mass, and avoiding rinsing more ...at one vpart than at another.. l gsi-T3 Y In f addition to .the describedv actions f of. .the upper,bafrles 34, they .perform a furtherV func.- tion in augmentingthe thorough. cleansing action on .the entire clothes mass. .Since the tub oscillates onA a vertical axis, and the bailles have fiat sides facing .inthe samedirection, asthese sides move forwardly, they Vengage the clothes .mass and move it part .wayaroundthe tub circurn, ferentiallyto occupy a different positionwith respect. tothe `main forces exerted 1 by the lower baffles. As these baffles move in .the ,reverseldirece tion.the.c1othes mass slideso'ff the slantingfaces thereof.A 'L The 'nexta' forward motion Lof. thefilat sides of. the baiiiesengages-a different .portion offfthe clothes mass, Vand -thus thelclothesr vare movedaround the vertical. axis with a.:stepb`y step .-motion, 'in addition to' all the othercmovementsimparted thereto. f. c E The; tub isoscillated by suitable mechanism, one -form of which isshown inmy copendingan plication,such mechanism being enclosed infthe easing 4| and operatively connected -.to .the shaft 81.

yieldability of the springs 2921in a direction. cir-'- cumferentiall-y of the-drive shaft, '-the springs being rigid in the up and downdirection. ,L y VThe diaphragm 33 hereof is made ofhigh grade durable soft rubber, or other materiallhaving sufficient weight, body or thicknesstobe firm and positive `in action, and sufficiently flexible to ensure its ready response to expansion andl contraction, as well as its ready conformation to the clothes mass whereby toinsure'uniformeffec` tive V'pressure thereon.VV It Avalso is inolded?v or formed-such that, in its contracted orrelaxed state,"it conforms closelyt'o -the 4shape of theftub,` and alsoto the baies'32,land 'toi other partsvof the lower agitator. Y 1 1 The diaphragmr'is somewhat semi-spherical or cup-like in shape, conforming, in general, to the inner lower sides of thetub 28, and having an upper edge peripheral bead |61. An expansion ring I'r'l engages Vtheulllpei' peripheral partfof the diaphragm, just under thebe'ad |61, pressing the same into the channel L92 formed in the tub Vside wallithis ring having' sufficient expansive force to hold the diaphragm'securely in place,`the arrangementv also providing a water tight'seal between the diaphragm'and tub; i' At its bottom, the diaphragm is fur'therfpro-.` vided with portions |68 of inverted l'substavnfially channel section: closely conforming to, and/ifirelaxed condition fitting over thebaffles 32. VDuring expansion, the diaphragm lifts off the bottom of the tub, rising from, the baffles and, since it vdoes not turn relative to the tubreturns easily and accurately to position fitting the bailies. 0 yl The ow of water, to and from the space -be' tween the diaphragm 33 and thebottom ofthe tub, to expand andy contract the diaphragm, is controlled by the diaphragmgvalve 36. `Water under pressure .is admitted by `the `valve V36,1 through the bushing 8.9, under or behind the diaphragm-,1 .tof-push: orf-experrdfrthe diaphragm l upwardly invtheflE tub.

AThe water supply to the valve 361s from an inlet pipe 21 secured to the disc-56 by af clip 212, throughA a conduit 2 I 6;A which. extends through'. an opening 2 il in thefshell 5l, to aI valve offth'efcontrol mechanism.. From vthe latter valve; "the Water- :is conducted through a conduit t8 i? which extendsthrough an opening -l82- into the shell 51; theV conduit |81I then extending upwardly through anipple 226"inthe bottom-wall ofthe housing 2J; It is iormed into a flat spiral section 221 (Figt 2) of. about two turns-surrounding'the drive shaft 871; before 4continuing tothe `valve` 36. The turns of the spiral are of relatively `large diameter and adapted to radially-contract and expand sothat the tub mayoscillate without-adversely l affecting thefluid connections V by reason of theV relative movement betweenthe/tub .ear-i r-ied vvalve 36 and thev stationary nipple 226W Arranging the conduit section 22T in. a nat spiral coil",v alsoY allows thebottom` ofvv the tub to the spaced from. the bottom. otl the housi'ngby a minimum distance, whereby to conservefspace-at a. place where such conservation is off importance in a selection of height for the housing. The. conduit section 221 maybe arranged otherwise', such asA to bend on a substantial radius or radii. to effect' substantially equivalent results.

Special provisions are-` made to'finsu're compiete draining' of the water from behind thediaphragrri S3;- and to insureagainst accidentalv and premeturecm'sing of the 'opening to the diaphragm valve. To this endg the lower-face of thebase sa of the'loweragitator has; an annui" groovei zu, having a peripheral portion'. The-head. otthe mounting bushing 8'9 lfor. the? diaphragm-valve 36 is received in the' groove 228;- r`The. base Minas' apertures 23ttherethroughv communicating with thegroove 228,; and the" peripheral portion 229 also yhas apertures 232.' communicating .withlfthe dlaphra'lgniyfit passes'throu'ghl 'the apertures v234 yand 232 tosta't the'diaphragmexpansion. f When Vthe Vwater fislbeingiexpelledffronr belowv the' 'dia'- phra'gnn-it drains?throughtheuaperturesf 232` and '234:V intothe 'groovev 228y and from the latter through the'fvalve A36vto thev tub housing 21 but withoutfrdanger ofthe diaphragm .fouling the opening.' .into the diaphragmfvalve 36.

At the beginning of the operation of the ma chine; the. operator'places the dry'clothes in" the t'ub'. The machine is lnext filled Awith water and soap, washing powder or'water softener added, after whichithe lid' 3 lr is locked. in'` place.

Ther dri-ve mechanism is yenergized to oscillate the-tub to produce-.agitation ici-the clothes-'and water At the-end vof a'selected washingtime period, th'eff'autornatic`- control mechanism lmay operate to fadmitwater behindthe diaphragmr33, through the valve .36,` to'beginu a ushing opera tonpfinl 'which the diaphragm lifts the .clothes and-Wash Watertowfard `the top of the machine so' that thetwashwateris gradually forced Vout throughthe-drain openingsv i734, in the lid, and theio'penin'g m6, in the-tub. Thus,l any scum andY matter'which has accumulated ontop of. the water i's-.flushed out yof the: machine. At .this time, *the` agitation of. theeA machine .has not stormed',y so that' the accumulated' matter alsois Iibera'tedffrom the clothes to float off. with the water. Inilation of the diaphragm may' continuefuntil: substantiallyv all of the wash Water -has `been extracted fromthe clothes at which time the valve SSoperate's to empty the water from behind the diaphragm,-v and the Vdiaphragnfi returns toits lower positionlshown.

' Bythis-time'the control mechanism operates to admit' Water tol the upper part of the tub, Aas through the centerof thelid to beginl therinsing operation. When suiicient water has been ad mitted to thetub to'make agitation ofv the clothes and water of so-me'benet, which is about one* thirdof the time consumed by the rinsing. opera'- tion,agita-tionY isI ive-started. Agitation continues during the remainder of the rinsing operation, and-for a suiiicientlength of time for the tub to completely fill with. water and `also to overflow through the-iducts |34 and Illl 'for a sufficient interval to' thoroughly rinse the clothes. At the conclusion'ofthe rinsing operation; the control mechanism Vagain opens the diaphragm water valveto again expand the diaphragm to ejectV the-rinse' water',fwhich is the beginning of the drying operation. Agt'ationiis continuedfurither until 'the diaphragm is above the centerof the tub; and preferably during about half of the periodk of time for this particular operation' of the diaphragm.V The'expansion ofA the diaphragm continues to"brirr'g' about drying of the clothes by" compressing the-same against the upper portions of the'tuloY and its cover, until all of the Water iseXtracted from'the clothes whereupon the supply of water behind the diaphragm is shut oi. Thenythe action of the diaphragm valve' 36 Willfagainoperate to dump the water from be'- hind the diaphragm. as explained above.

Other modifications may be madeV in the ar rangement and location off-parts within the spirit and scope of'my invention, and such modifications are intended to be covered by the appended claims.
