The object of this inventionjis to provide 7 an efiicient machine by the use of wh1ch clothes may be rapidly and thoroughly cleansed and subjected to the direct action of hot water or steam directed thereonto' in a plurality of fine streamsfor jets. The invention also includes means whereby the clothes will be subjected to an oscillatory movement transverse to their line of travel without injury while passing through the machine and will also'be subjectedto an efficient rubbing action. The invention resides in certain novel features ofconstruction'and arrangement which will be hereinafter first fully described and then more particularly defined in the appended claims.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a top' plan view of the machine with the covers removed; 7 i Fig. 2 is'a central longitudinal vertical sec tion' through the machine?

In carrying out the invention, there is provided atub 1 which may beof any approved form having sufficient strength and durability and supported in any convenient manner was by legs .The tub is preferably rather shallow, as shown in Fig; 2;;and irreludes covers 3 which will prevent thewater, sudsand steam escaping through the top of 4, the tub and will retain thesame therein so that they will" act thoroughly upon the clothes. Each cover 3 comprises a plate having notches 4 at its inner edge-whereby it, is

adapted to fit around the rubbeifhang'ers-and 59 at ts u er c rne formedwithes e 1928'. serial in. 216,419;

5"whereby it isadapted to fit around the standardsor posts in which the bearings for thewringer rolls are mounted. At each end of the tub I secure posts or standards 6 having vertical slots 7 formed in their upper portions; as shown most clearly inFig'. 5, and in the said slots are. s'lidab'ly mounted bearing blocks 8 receiving the trunnions 9 of upper vwringer: rolls 10', while the trunnions ll of lower'wri'n'ger rolls 12 are fitted in the respective s'tandardsor posts below the slots.

Mounted in the upper end of each standard "is anadjusting stopscrew 13 which is adapted to bear'against the top of the bearing blockB and thereby limit the upward move"- ment or thesame', and these severalscrews can respectively be adjusted so astohold the upper roll to the clothes with anyfdesireddegree of pressure. Inimediatelyadj'acent the wringer rolls, at th'e' outer sidesthereof,

an apron'or drain board 14 is carried by the end wall of the tub' so that any water which may drip or be expelled from the clothes passing'from between the rollers at the outer sides thereof will be deflected back into the tub. i

f-Referring more particularly to Figs. 2 and 3', it will be" noted that the bottom of the tub'inclines upward from' its central portion toward each end and extending parallel with so the bottom of the tub are lower rollers 15 forming a continuous series extending from one pair of wringer rolls to the" other pair ofwrlnger rolls. These lower rubbing or presser rolls are each provided with'trunist nions' or axles fitted in bearing boxes 16 Secured on the side walls of the tub'andbetween said bearingi box' and-the working; portion of each roll' a sprocket gear1'7 is secured upon" the axle or trunnion. Sprocket chains 18"a1 e'trainedabout the sprockets 17 in series; as will be understood on reference to Fig. 1 so" that all the lower rolls will be caused to rotate in unison; The'rolls are formed upon'their peripheries withv annular grooves 19 which are disposed "obliquely or spirally and the grooves upon adjacent. rolls are arranged reversely relative to each other. As arresult'of this reverse arrangemenfi'the $1151 1; operation not nly a t 1 d l 111-15 clothes through the tub but also impart thereto a transverse movement alternately in opposite directions as the clothes pass through the tub. It will be observed upon reference to Fig. 2 that the outermost roll at each end of the series of rolls 15 is disposed approximately in the same horizontal plane with the adjacent lower wringer roll and the series of rolls follows the form of the bottom of the tub and is disposed parallel therewith throughout the length of the machine; Secured to the side walls of the tub over the inclined end portions of the series of'rolls 15' are rails or guide blocks 20 in which are secured guide pins 21 extending downwardly from the rails to .pass between or through the subjacent supports for the lower rolls and slidably mounted upon these pins are carriers 22 in the form of bars arranged substantially parallel with the rails 20and of similar form and each forming bearings for the journals or trunnions 23 of upper rollers2 l. The rollers 24 are similar in form and dimensions to the rolls 15 and have annular grooves 25 which are arranged reversely to the grooves in the immediately subjacent rolls 15 so that clothes received between the two sets of rolls will be effectually engaged and not only fed through the machine but also shifted transversely in opposite directions alternately so as to be subjected to a thorough rubbing action. Expansion springs 26 are disposed be tween the rails 20 and the respectively subj acent carrier bars 22 and act upon said bars to yieldably hold the upper rolls toward the lower rolls and thereby maintain the desired pressure upon the clothes without binding upon them so tightly that the clothes will be damaged.

Obviously, the central portion of the series of lower rolls will be disposed substantially horizontally. To cooperate with the central portion of the series of rolls, I provide a rubber comprising a plurality of rolls 27 which. like the rolls 15 and 24, are provided with annular grooves arranged oblique- 1y or in spirals and in reversed relation to the grooves upon adjacent rolls. These rolls 27 have their trunnions or axles mounted in end blocks 28 which are connected by cross bars 29. and upon the cross bars at the ends thereof are secured bearing plates or caps 30 carrying pivot pins or bolts 31 upon which are pivotally mounted the lower ends of hangers .32., said hangers passing through the notches 4 of the covers 3 when the parts are all assembled and the machine is in operation. In their upper portions, the hangers are each formed with slots 33 and 34, as shown clearly in Figs. 2 and 3, the lower slots receiving a fulcrum rod 35 which is secured in the side walls of the tub and extends entirely across the tub, this arrangement permitting 'vertical movement of the'hangers and also causing them to oscillate or rock about the rod as a center. The upper slots 34 of the hangers receive the crank portions 36 of a driving shaft 37 so that, as the shaft is rotated, the cranks will impart an oscillatory movement to the hangers and thereby cause the rubber rollers 27 to move back and forth over the clothes and by their travel over the clothes held upon the central rollers 15 will loosen any particles of dirt which may be clinging to the clothes so that as the clothes emerge from the tub they will be 'thoroughly cleaned, it being understood that the action of the water and steam delivered into the tub is to remove all surface dirt and also drive from the clothes any grease or other matter which may have collected in the fabric. To minimize the frictional wear between the cranks 3G and the walls of the respective slots 34: in the hangers, bushings 38 are fitted around the cranksto extend-through the slots, as will be readily understood.

The ends of the driving shaft 37 extend through standards 39 secured to and rising above the sides of the tub and are journaled in bearing boxes i0 carried by said stand ards, as will be understmid. Upon one end of the driving shaft are mounted loose pulleys ll and a fast pulley 4:2 between the loose pulleys, belts 43 being provided to cooperate with the pulleys and transmit motion thereto from any convenient source of power, it being noted that one of the belts is straight and the. other is crossed, andthe driving shaft will be driven in one or the other direction accordingly as one or the other belt is shifted onto the fast pulley. .Vhen the 1nachine is not in operation, the belts will be trained around the respective loose pulleys, as'shown in Fig. 4, but when the machine is to be used, the belts are shifted. so that one or the other will pass around the fast pulley. and to accommodate the belts in either of their shifted positions, the loose pulleys are twice as long as the fast pulley or the width of the belts. At the opposite end of the driving shaft, I secure thereto sprocket gears 44 about which are trained sprocket chains 45 which pass from the respective gears to the ends of the tub andare there trained around sprocket pinions 46 secured upon the outer extended ends of the trunnions of the outermostrollers 15 whereby rotation is imparted to the pinion 17 on said trunnion and the chains 18 driven. The last-mentioned trunnions carry pairs of sprocket pinions outside the tub and the inner sprocket of each pinion is operatively connected by a sprocket chain 47 with a sprocket pinion 4-8 on the trunnion of the adjacent lower wringer roll. It will thus be seen that the rubber is osc llated, thelower rollers 15 are positively driven. and the lower wringer rolls are also positively drivenfrom the single driving shaft, and the wringer rollers 15 an d the lower rubbing rolls are rotated in the same direction one end a yoke 50 provided with slots 51 engaging around the respective belts whereby if endwise movement be imparted to the shifting bar the belts will be likewise shifted so that they will be set in a desired position to cause rotation of the driving shaft in either direction or to stop the operation of the machine,

Mounted upon that standard 39 more remote posed rocking arm 52 provided at its upper end with a crank 53 which extends over the shifting bar 49 and is engaged in asocket or recess 54 in said bar so that, when the arm is rocked, the crank 53 will impart an endwise movement to the shifting bar. At its lower end the rocking arm 52 is provided with a laterally extending crank 55 which forms a convenient handle whereby the arm may be rocked by an attendant standing adjacent the center of the tub. As it is frequently'desir-. able to control the operation from the ends of the tub, a rod 56 is slidably supported in any convenient manner upon the side of the tub and extends from end to end thereof, being provided with any convenient form of handle 57 at each end. Adjacent its center, this shifting rod-56 is formed with an eye or loop, 7 indicated at 58,, which is engaged around the crank 55 so that any movement imparted to the rod 56 will be transmitted directly to said crank and through the same to the rocking arm 52.

Secured in the sides of the tub adjacent the 7 ends thereof and over the presser rollers 24- are supply pipes 59 each of which is closed at one end and is provided at intervals with depending nozzles or jets 60 directed toward the subjacent rollers 24, as shown clearly in Fig. 2. The open ends of these pipes 59 are coupled into pipes 61 which. are mounted on the side of the tub and extend to a'boiler (not shown) to lead steam and hot water into the tub, and in the said pipes 61 are mounted.

valves 62 whereby the flow of steam and hot water may be cutoff or regulated. V

In Figs. 7 and 8, I have shown 111 detail the structure of the hearings in which the several Y rotating parts will be mounted, the details of this structure not appearing in the other figures, owing to the reduced scale of the latter.

. In Figs. 7 and8, the numeral 63 designates a :shaft or trunnion, as, for instance, the trunnion of one of the rollers 15. Within the bearin block 6% thetrunnion hasfitted there p: o 9 l I n on bushings 65 and around said bushings rolls In the upper side of the bearing block 641 is in the respective end reach andsoil the clothes.

From the foregoing description, taken'in connection w1th the accompanying drawings,

.it will'be seenthat I have provided a very i 'eflicient and easilylo'perated machine whereby from the driving pulleys is a vertically dis-Q clothes may be rapidly and thoroughly cleaned. .As' the main driving shaft is 1'0- tated, the hangers or pitmen suspended thereon will oscillate the rubber over the clothes and the slotted construction of the hangers permits the rubber to readily accommodate'itself to the bulk of the'clothes passing through the machine. To lighten the work, it is desirable that the clothes be permitted to soak within a vesselcontaining terthe tub between'the wringer rolls at one end thereof and surplus water willbe thereby squeezedi therefroln and this surplus water will'be caught by the adjacent drain board 7 14 and directed into the tub. From the wringer rollsfthe clothes are passed to and between the adjacent'upper and lower rolls .24 and 15 and will'be fedthrough the machineby the positive rotation of the lower rolls; The -upper rolls will press yieldably. upon the clothing so that it will be positively ".5:

engaged by the grooved circumferences of the :opposed'rolls and will,consequently, be given atransverse vibratory movement as it passes through the tub so that loose surface dirt will b'eremovedf At the center of the tub, the I;

clothes. will be acted upon by the rocking rubber and will then pass between the second -set of rolls 24s and 15 to be discharged between the second wringerrolls. Thehot water and steam which enters the tubover the re- 3.: spective yieldably mounted upper'rolls will saturate the clothing and drive "therefrom any dirt or other matter which may have penetrated the fabric so that, when the clothes are finally drawn from the tub, they will be thoroughly cleaned. The dirt removed from the clothes will, of course, settle at the bottom of the'tub, and a drain valve 71 is provided to draw off the dirty water after the washing operation is completed. 7
