" To all whom it may concern:

Be it known that I, EMILE :C. RnU'rLiNenn, a citizen of the Republic of Switzerland, and a resident of Boston; county of Suffolk, State of Massachusetts,have invented an Improvement in ashing Machines; ot which the following description, in conned tion' with the accompanying drawi11g,-.is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in washing machines and the general object thereof is to provide a washing machine which is more economical and elfic-ient in op eration than those which have'heretotore been produced.

More particularly the invention relates to washing n'iaohines-having a reciprocable dasher provided with means preferably suction cups, for engaging the clothes which are adapted to press the clothes during the movement of the'dasher in one direction and to loosen up the clothes as the dasher moves in the opposite direction.-

In washingmachines of this type the dasher head is usually moved from aposition above the level of the water in the tub to a position in proximity to the base of the tub. The buoyancy of the water tends normally to raise the dash-er so that a greater force is required to remove the dasher from the water than during its immersion in the water. 7 i v One of the objects of the invention is to provide means for raising the dasher which will apply a force correlated to the resistance or weight of the-dashenlonversely, when the dasheifis depressed and particularly when it eng' ges the clothes in the tub 'a greater esistance is offered during its preliminarymovement.

Another objectof the invention is to pro vide means which will. exert a progressively increasing force upon the dasher during its downward movement.

Another object of theinvention is to provide a washing machine of the character above described with asingle-acting tiuid motor for movingthe dasherpin one direction. preferably in the direction toraise the dasher. By employing. a single'acting fluid motor of this character the amount of fluid required to operate the machineis greatly'decreased over that whichis required in the usual double-acting motors.

A further object of the invention is to provide leverage mechanism operable by a single-acting motor which will multiply the leverage required to raise the dasher in' correlation to the weight or resistance of the dasher during the elevating movement thereof.

Another object of the invention is to provide a washing machine'having a singleacting fluidsactuated motor for moving the dash-er in one direction with spring-actuated means acting progressively to'increase the force applied to the dasher when moved in the opposite direction. i p

A further object of the invention is to provide a single-acting fluid-actuated'inotor with valve mechanism controlled by the movement of the dasher in such a manner that. the valves will'be actuated only as the dasher approaches the upward and down ward limits of its movement.

A further object of the invention is to provide a fluid-actuated motor for a washing machine with novel valve-actuated mechanism capable of permitting the exhaust valve to close in advance of the opening of the inlet valve whereby a saving of water may be effected. 1

i A further object of the invention is to provide a fluid-actuated motor of the character described with means acting upon theexhaust tromthe motor to control the-speed of the motor.

A further object of the invention is to provide a washing machine of the character described with a fluid-actuated motor in which the cylinder and piston may be removed and replaced so that'difierentsizes of cylinders and, pistons may be employed f for different water pressures.

A further O'lflet't of the invention is to provide means for rotating the dashers 1ntermittently but notpositively, preferably,

but not necessarily, in asinglc direction.

A further object of the invention is to provide novel means for imparting a rotative movement to the dasher head including a frictional instrumentality capable oli permitting slippage it substantial resistance is imposed against the rotative movement of the head.

A further object of the invention is to rovide novel means for rotating said head including a frictional instrumentality which is only operable to rotate the head during the reciprocating movement of the dasher.

A further object of the invention is to provide independently yieldable supporting means for suction cups forming a part of the dasher head.

A further object of the invention to provide a washing machine having: a. fluidactuated motor which is so arranged that the mechanism is never on a dead center and can, therefore, always be readily started.

Other objects and features of the invention will more fully appear 'trom the -tollowinp; description and the accompanyinp d airings and will be particularly pointed out in the claims.

A preferred embodii'nent is illustrated in the accompanying drawings. in which,

Fig. l is a side elevation ot a washing ma chine, emljiodying the invention, set upon a tub which is shown in section a portion of the dashcr head being broken away and shown in vertical section;

Fig. 2 is an enlarged detail view. mainly in vertical section. of a rn'ctcrrcl'l single action motor oi the type illustrated in Fin. 1;

Fig. I3 is a detail view, mainly in vertical ii cctioni through tlltt dashcr head illustrating the means tor imparting: relative movement thereto. the suction cups ot said head being omitted:

Fig. l is a detail view in vertical section ot the end ol' the valve casino; oi the motor, showing in section a cylinder ot larc'o diameter secured to said casiivc adapted to he used upon fluid systems having: low prcssures and showing: in dotted lines a cylinder t smaller diameter adapted to he substituteiil when the motor is coimccled to high pressure systems.

The washing machine is illustrz'ited in Fig. 'l as being; mounted upon a tub having a bottom 1 and vertical sides 2 which may he ot the usual type which are tound in laundri s and kitchens. The washing nuich ne comprises a casing having sides 3 and a top :l:

and ends 5 which preferably are made ol' cast metal and prodded with a removable cover not shown. The lower ends of the sides 5 desirably are provided vith inturmid flanges 6 to which are secured blocks 7 having dovetail grooves to receive arms 8 of brackets 9 provided with bifurcated ends 10 adapted to embrace the walls 2- ot the tub. lhcsc bifurcated ends may he provided with tasici'iing devices for securing the same to the tub, but preferably are ot sutiicicnt length to enable the entire machine to he raised. it the dashers encounter an undue obstruction which would be likely to injure the mechanism of the washing machine.

The dasher ot the washing machine comprises a preferably vertical dasher bar ll having at its lower end a rotatable head which as shown comprises a plate or spiifler 153 which carries a plu'ality of plungers preferably in the term of suction cups 13.

In the preferred construction disclosed herein the dashcr is given a vertically reciprocating movement, being raised by a single acting pump which operates upon said dasher through a leverage system which acts with increasing leverage as the dashev is raised. The downward movement; ot' the dasher may be produced by gravity alone, but preferably resilient means are employed which act with pregressivel y increasing force upon the dasher during its downward miwemcnt. In the particular mechanisnn illustrated the upper end of the dasher bar 11 is connected to the lower end o'l. a tlexihlc member or chain let, the upper end oit which passes around, or as shown is connectml to a rotatable member 15 having a cam face 16 which engages the flexible member l-st. The same or preferably another flexible member or chain 17 passes over another cam surface upon the rotatable member 15 and is connected at its opposite end to the arm '18 ot a hell crank lever the end o l which arm is provided with :1 'am surtacc 19 likewise adapted to engage the flexible member or chain. 17.

The bell crnnli lever is pivoted upon a l lul Eltl (.llt'lltlltlgl inwardly 'l'rom the side ll of the casing and the other arm ot' the hell crank lever preferably is provided with a V--shaped notch ill to receive a knife edge 39, upon the end of the piston rod 533 ot" the singzlc actiug tluid-iu'tiuitcd motor.

The piston head which is (.Ullllit'tttl to the piston rod 522). may he ot any suitabl charactor but preferably coumriscs a r ip-shapcd rlcvicc ol' tlcxiblc material (scc l iu. it) c amped between collars .lfi and iZt' which. are secured upon the reduced cud :2? ol the piston rod by a suitable nut 28" The piston head is rceiprocably mounted in a cylinder fill which may he ol" liltlhrh steel. or other suitable material. and is provided with a inccli 30 having a screw threaded outer wall by means of which it is connected to a valve casing ill. liy reason ol this constructimi the cylinder, the piston and its rod can readily be removed and a la rpger or smaller cylinder and piston substituted therefor in accordance with the fluid pressure ot' the system to which the motor is attached.

It will be umlcrstood that fluid motors ot this type are usually actuated by the water upon thiusual systems which are installed ltlfi llt) lll?

lfltl lllll in houses and as the pressure in the various water systems varies greatly it is desirable that a suitable piston and cylinder may be employed to operate properly upon the pressure present in the pipes of the laundry or kitchen in which the washing machine is installed. This feature, therefore, of pro viding replaceable cylinders and pistons is of great importance in order to obtainthe proper operation of the machine and also in order to enable ready repair and replacement of the cylinder orpiston when either becomes worn.

Any suitable valve mechanism may be employed for controlling the supply and exhaust of the fluid to the motor, but preferably a special mechanism is provided as will hereinafter be more fully described. J

In the operation of the device the buoyancy of the watertends normally to raise the dasher so that less power is required to elevate it while it is submerged thantha-t which is required to raise it afterward particularly where the head oftlie dasher-is provided with suction cups which-enclose a consider-- able amount of water. By properly propo-rtioning .the lever arms 21 and '18 of the bell crank lever and properly designing the @ cams 19, 17 and 16 of the rotatable member 15 practically the same'fluid pressure force upon the piston will exert a varying lifting power upon the dasher. thus requiring a mininiui'n amount of fluid pressure to actuate the dasher.

It is desirable that thevalvesactuating.

mechanisn'i for the single-acting fluid-operated motor shall beso' designed that :the inlet and exhaust valves will be opened andclosed respectively only as the dasher approaches .the limit of its "stroke. One of theii'eatures or the, present invention relates to novel valve mechanism which is controlled by the movement oilf 'the dasher to effect this purpose. I

ln thepreferred construction disclosed herein the valve casing 31' comprises a cylindrical inlet section 32 and a cylindrical outlet section 33 extending at rightangles to said inlet section. The inlet conduit 34 is connected by a suitable union to the inlet section ol the valve casing, anannular llange 35 of a valve cage or guide 36 being clamped between thefabutting ends of the inlet conduit and the inlet of the valve casing. The inlet :end of the valve casing desirably is provided witlran inwardly extending rib 37 which forms a seat for a gasketSS which forms the valve seat. The inlet valve 39 desirably is of conoidal form having a flat base adaptedto engage the valve seat 38. Thevalve 39 -is screw threaded upon the end of a valve stem 40 and is secured thereupon by a suitable'nnt.

engages the base of the valve 51.

a bell crank lever. one arm l2 otwhich is mounted upon a pivot 43 upon a block which is located in a downward extension'or nipple 45 upon the valve casing'and is se cured in place by a cap l6 screwed upon said nipple. The other arm 47 ol the bell crank lever provided with a downward extension l8 which is connected by a pivot -19 to the lower end of the valve stem 50 of the exhaust valve.

The exhaust valve 51 desirably is of'conoidal form and provided with a flat face adapted to engage a valve seat 52 which is clamped between a shoulder upon amin wardly projecting .ribol the outlet section and the abutting end of an outlet conduit 53 which is secured to the casing by a collar having an inwardly extending flange engaging a complementary flange upon the outlet conduit and' which isalso provided with internal screw threads engaging externalscrew threads upon the outl'et'section 33 V oi -the valve casing.

The exhaust valve 51 desirably is slidably mounted, a reduced portion 55 of the'valve stem and collar 56, which is located at a short distance from the normal position of the base of the outlet valve when closed, serving to engage the valve upon downward n'iovement of the valve stem 55 to force the valve from its seal. V 7

As illustrated in the present construction the inlet valve is in open position with the piston ready to travel upon its working stroke. W hen thc piston has approximately reached the end of its working stroke the exhaust valve stein is torced downwardly by mechanism which will hereinafter be de- ',scribed, thus first moviug'the inlet valve 39 towards closed position be'iorethe collar 56 Further movement will cause the complete closing of the inlet valveSQ and opening of the exhaust valve. 51. 'The weight of the dashei'. and in the specitic construction illustrated herein also the action of the spring, will then forcethe piston toward the valve casin thereby causing the fluid to flow from the motor through the exhaust port, the outlet conduit 53'to the waste conduit 57 until the piston has approached the limit ofits exhaust stroke, whereupon the valve-actuating inechanisn'i hereinafter described will be actuated by the movement of the dasher to raise the stem 550i the exhaust valve. As soon as the valve stem tifibegins its upward movement the. exhaust valve is raised by the water pressure to close the exhaust port, by

reason of thetact that the exhaust valve 51 i is slidably mounted upon its stem; consequently,the exhaustvalve will becloscd betorethe inletvalve is forced any consider abledistance from its seat.- By reason of this construction, therefore, a considerable saving of the fluid or water isattained.

A further 'liature ol' the invention eoneiets in providing means for regulntiiig the speed of the motor by controlling the flow 3E iluid through the outlet. lhe preferred nieehanisn'i illustrated in the accompanying drawings "for aeeoniplishiiug; this purpose eoinpris-res a nipple 58 which is Screwed upon the end oi the waste or discharge pipe 5? and in 1HfOYl'vl8t'l with a eoiuluit having; a preile ahl v eonieal end (it) adapted to seat upon a eoinplelnenl'ar v conical "all til in the end of the disehar 'e pipe :37, the conduit f ll heine; seeiued fully to the nipple 58.

Resilient means are provided for actual ing these levers. In therpreterreil construcrocker 66.

lion the lovers are connected by a. helical tension spring '75 norn'ially tending to force the Cain-shaped ends (59 and 70 into engage ment with the stud (38 upon the end of the rocker. The Sliding; ineinher, llOWOVOl, is provided with a pair oi. lugs T6 and 7'? which engage the respective levers upon the no ward and downward i'novenients of the slide, therehv removing the ends 69 and 70 ot the levers respectively from ei'igageinent with the stud and placing the spring under tension alternately by the upward and (mwnward movement ol' the rocker.

The rocker is also provided with a rigid, preferably integral, downwardly extending plate 78 hnvingj upon it a. ozun 79 having pre'lerahlv areuate parallel :liaees which alternately engage n stud 80 upon an evtension on oil the sliding nieniher 63 and restrain the lllOVillMJli? of the valves until the stud 80 pa en hevond the end ol. the cam thereby preventing movement of the alves until the dnehei: approaches the upward and downward limits of its stroke.

In the operation ot the device the down ward movement of the daehei' moves the roehei' on ahout its. pivot (55 raising" its opposite end which carries the stud (38 thereby engaging the emu-shaped end (if) oi the lever 71. and raising; the lever imposing a tension up on the sowing T5.

In the meant me the movement of the rocker 66 causes the stud 80 upon :theextension 63* of the slide to engage the upper surface of the cam 7 9 upon the rocker plate 78, thus restraining thedownward movement of they sliding member until the dasher approaches the upward limit of its stroke, whereupon the stud '80 rides over the end of the cam 7 9. and the tension of the spring. acting through the lever '71 upon the stud on the sliding member, forces the sliding member dow wardly, thereby depressing the piston stem 55, opening the outlet valve 51 and closing theinlet valve a0. It will be remembered that the outlet valve 51 is loosely mounted upon a stem and operates during the upward movement of the valve stem 55 to'close the outlet port before the inlet valve fully opened, thereby effecting the saving of the j fluid which operates the motor.

-..It has been stated that the single-acting motor operates to move the dasher in one direction only which, as llustrated herein,

is in the upward direction. The downward movement of the daslier may be caused by gravity alone,- but preferably means are provided foriinposing a progressively increasing force upon, the daslier as it descends that when the dasher is engaged first by the water in the tub and afterwards by the mate'- rials being cleansed, a greater force can be imposed upon the dasher substantially lII' proportionto the resistance which is enrountered bythe daslier.

Preferably this is accomplished by resilient. means which acts progressively upon the daslier with increasing leverage during its descent and conversely acts upon the dasher with decreasing leverage tllll'lllglis ascent.

In the preferred :onstruction illustrated a lever 82 is fulcrumed upon a stud 83Jcarried by a bracket 84; extending downwardly from the .side 3 of the casing. The opposite end of the lever .82 is pivotally connected.

by a stud 85 to the dasher bar 11 The lever 82 is provided intermediate of its ends with an upwardly extending arm 86 preterably lying in the plane of or parallel to the lever 82. .Preferably the lever 82 is in the form of two parallel connected plates which extend upon opposite sides of the cylinder 29. The arms 86 of the lever are provided with V-shaped, upper ends forming knife edges 87 which engage the angles of V- shaped end portions 88 of a yoke 89' having a cylindrical stem 90 which isteles'copically mounted in a cylindrical member .91 which is pivotally mounted at its'upper end upon a stud 92 projecting from the side 3 of the casing. A helical compression spring 93 is interposed between the collar 94 upon the upper end of the ycylindrical member '91 and the shoulder 95 presented by the upper walls of the yoke 89.

Dinning. the operation of the device the raising and lowering of the dasher rocks the lever 82 about its fulcrum 83 thereby cans.

ing the V-shaped upper end of the arm or arms 86 to move through an arcuate path from substantially the fullline position i1- lustrated in Fig. l to the dotted line position so that during the upward movement of the dasher the efi'eotive leverage applied by thespringnctuated instrumentallty to the lever 82 is progressively lessened and conversely during the downward movement of the dasher the effective leverage applied by the spring-actuated instrumentality to the lever 82 is progressively increased. Thus by the leverage mechanism which connects the pis tonrod 23 to the dasher the power applied to the dasher upon its upward inovement is correlated to the resistance of the dasher as it mechanism which will open toperinit the escape of air and water from the Q3 cups during 'he downward.movement of the dasher and which will close-during the up ti on war-d movement of the dasher. V

A further feature of the invention coin sists in so mounting the suction cups of the dasher head that they inay yield independently upon engagement with undue obstruction as from a bunch of clothes, and a further feature of the invention consists in providing a novel mechanism for causing inter inittentybut not positive, rotation of the cups either in one directionv or alternately in opposite directions during the recim'oeatiiig movement-of the dasher.

In the particular construction illustrated herein the lower end of the daslier bar 11 is provided with a lateral extension 96to which a downwardly extending shaft 97 i secured.

ineferablyhy a cylindrical extension 98 of less diameter than the shaftwhich projects upwardly through the dasher bar extension 96 and is riveted'at its upper end. the shoulder between the extension 98 and the shaft 97 abutting against the under face of the extension 96 of the dasher bar. A, sleeve 99is rotatably mounted upon the shaft 9'? and desirably is'provided with an upwardly extending enlarged toothed upper end 109 which engages complementary teeth upon a sector 101 fixedly secured upon the end of the arm 82.

The daeher head comprises a spider 102 preferably having radially extending: channel-shaped arms 103 and provided with a hub 10% having an enlarged flange .105. A plate 100, having a hub provided with an angular recess titted upon a complementary angular extension 107, is supported upon a retaining plate 108 which is secured to the shaft 07 by a screw 100. The plate 100 is provided with an annular flange 110 com plei'nentary to the flange 10:) oi the spider 102 and a friction dielc 111, prelerablv oi librous material, is interpo:.-:ed between the thinned portion oi the spider and the flanged portion of the plate 101$, a slight clearance being provided which will permit rotation 01 the spider it p1 ssure is not inu ioced upon it, but when pressure is imposed upon the spider by the movements 01 the dasher the flange portion oi the spider will enc'ap e the friction disk with sutiiciei'lt Force to clamp it upon the flanged portion of the plate 106 and thereby cause it to be rotated by the rotation of the sleeve 99.

While the frictional mechaniem is illus trated in the present construction as being; located below the sleeve it will be readily understood that by a suitable u'iodilication it may be located above the rotatable sleeve or otherwise, to produce rotation at the head during the downward movement of the plunger instead of the upward movement, or if desired "friction devices may be so located as to produce a non-poaitive oscillatory movement 01 the plunger.

Suitable plungers or suction cups may be secured to the spider 102 in any suitable manner. As illustrated herein means are provided for peri'nitting the planners or auction cups to yield upwardly independently. As illustrated herein arms 112 are :t'ulcrumed upon studs 11 which are lixedlv secured in flanges 11%1 of the spider arms and each arm 112 is connected at its outer end to a bell-shaped sheet metal member 115 by a bolt 116 having a head engaging the upper lace of the arm and provided with a nut 11? engaging the under face of the hellshaped sheet metal members 115. The bolt 116 extends downwardly some distance and is provided with a section 118 of eun'dler diameter upon which a circular alve plate 119 is secured by a nut 120. The periplun'y ot the valve plate 119 desiraoly provided with a libroua covering 121 such as usually used to insure proper engigement at the valve with its aeai. l lac-a of the suction cups i3 is ot bell shape, the upper end being" ot a lesser diameter than the diameter ol thc hell shaped member 1153 and provided with an inwardly extending l'laneje 122 which overlies the periphery ot the valve plate 11%} a considerable distance. The length of the bolt 116 is such that when the dasher is raised the bell-shaped suction member will rest upon the upper surface of the valve 11!) and close the port 123 in the upper portion of the suction member. Thus as the dasher aacende the suction cup will be sealed and retain the water which it; in it until the lower edge of the suction cup is raised above the level of the water in the tub. Upon the downward movement, however, of the dasher the suction cup will be rained by the buoyancy of the water no as to unseat the flange 192 from the valve and thereby permit the air and water to escape through the port I23 during the downward nuwement ot' the dasher.

13y reason of the engagement; of: the toothed periphery 100 of the sleeve with the teeth at the sector .101 which is pivoted upon the daaher the vertical reciprocating; movement of the dasher will oscillate the sector and cause rotative movement of the sleeve 00 lirat in one direction and then in the other. During; the downward movement of the dasher the suction cups will engage the water and will be raised by the buoyancy thereof and in turn will raiee the spider out (it intin'iate contact with the :tric tion d sk 111 so that the sleeve will rotate idly. Upon the upward movement 011' the dashcr, however, the weight oi" the suction cups which are then tilled with water will impose a downwardforce upon the spider which will cause its llange 10:") to clamp down upon the friction disk 111 and force it firmly against the flange 110 of the plate 106 which is secured to the sleeve that the rotative movement of the sleeve, caused by the oscillation of the toothed sector during the movement oi? the dasher in the upward direction. will rotate the spider and the suction cup. It, howeveri the suction cups engage an obstruction, such as av bunch of clothes, sutlicient slip iapge will occur between the spider, the friction disk and the plate to prevent a ny injury to the clothes or undue strain upon the actuazingg mechanism.

As has heretofore been stated, washing inachinea of this type are usually actuated by the tluid pressure of the water in the usual water pipe systen'is ot lions-ea, apartments, etc.. and such prei sure varies through a very wide range from twenty-five pounds or less to one huiulred twentydive pounds or more. It is desirable. there'hire, that the washing machine motor shall be so con structed that a suitably sized piston and cylinder may be employial tor the water pressure which is present in the place in which the machine is to be inetalled.

Another feature of the present invention consists in providing; means by which a cylinder and a piston which are unsuitable to the water pressure in a predetermined andanother cylinder and piston of proper cylinders 7 heretofore describedthe cylinder '29 is proplace may be removed and another cylinder and piston substituted}therefor. This is accomplished in the present construction by providing a plurality'of interchangeable and co-operating. pistons. As

vided witha reduced-end having an exteia nally screw threaded wall which engages the 7 screw.threadedrinnerwall of; the end 31 or the valve casing and can be readily removed.

Likewisefihe QHtlOfftllGldlStOll rod is'pro-' vided with a knife ed 'ewhich en a es the b b b apex of a -V-shaped recess in the end of the By simply unscrewing I the cylinder 29 it can be removed and the,

bell crank arm 91-.

piston rod removed with equal readiness diameter for theplressure or the system substituted. This'is. graphically illustrated in the enlarged detail view Fig.4 in which the cylinder 29 is illustrated. in full lines as being providedflwith an externally screw threaded extension 3O engaging internal screw threads of the extension 31 of the valve cas ng and in dotted 111168 a cylinder 12a of smaller diameter which likewise is provided with anexternally screw threaded extension adapted to fit the screw threaded internal wall of the end 31 or the valve casing; a w I r Suitable means are provided for arresting the action of llllQ ClElSllGl; As illustrated herein the arm 21 of the bell crank lever which is actuated by the piston is provided near its lower end witlra shouldered lug 125 .which is adapted to be engaged by the shoulder 1260f a latch 127 which as 'illustrated is in the form of a. sector pivotally mounted upon a stud. 128 projecting laterally from a. bracket 129011 the end 5 ofthe I casing. The latch 1:27 extends throngha slot iirtlie sectorlvand is provided with a shouldered. extension 130 whichengages the casing 5 when the latch is in looking posi- 11011.. Thev latch also is provided with a lever 1.31. by means of which it may be swung about its pivot outo'f engagement with the sector. This latch isso positioned as to engage the lug 125 just after the piston has made its full stroke and at the time it is starting upon its returner exhaust stroke.

Iii'order to start the machine it is merely necessary to pull the lever -131 over to release the latch'from engagement with the lug 125. Thereupon 1 the weight of the dasher will cause it to descend and as it dethey descend. .During this movement the piston'rod 23 will move (to the left), in

such amanner as to force the piston to--- wards the head of the cylinder. Durii'igthe descent of the piston the toothed sector 101 will rotate the sleeve 99 in one direction, but the head will beraised by the buoyancy it the water so thatno substantial rotative movement will be imparted to it during: the downward movement of the plunger. hen the plunger approaches the limit of its downward movement the outlet port and opening the inlet port in the manner above described. lVater will then flow into the cylinder forcing the piston in As the piston is the opposite direction. progressively forced along the cylinder the leverage in'echanisn'i, which connects the rocker 66 will be actuated sut'iiciently to piston rodwiththe dasher, will raise the dasher with a progressively increasing force in correlation to the resistance imposed upon it by the weight of the dasher and the water contained in the suction cups 13 which auton'iatically seat upon the valve 119 as the piston is raised. During the raising; movement of the dasher the spring-actuated instrumentality, which engages the lever 82, is swung progressively toward a position more nearly in alinement with the fulcrum 83 of the lever 82 so that the force of the spring upon the piston is progressively decreased until the limit of upward movement of the piston is reached.

By reason of the'construction above described the mechanism operates in such a manner'that it is never upon a dead center so that the operation will not cease unless arrested by the operator. r v

The speed oi? operation of the machine may be adjusted from a maximum to a minimum by properly adjusting the valve 67 which controls the effective area otth'e outlet port. v

Byreason of the construction above de scribed a washing inachine is provided which will operate at a maximum etficiencv, with a minimum consumption of fluid, and may be controlled to operate at any desired rate of speed.

-In this construction the dasher head can be readily removed by unscrewing the screw 109 thus enabling the washing machine to be readily placed within the tub when no:

in use if the capacity of the tub is not suiticient to permit the washing machine in its assembled position to be placed within the tub. Thus the machine can be readily stored when not in use.
