1'0 claims! ows-#253) This'invention relates to a clothes wringer embodyingthe importantcharacteristics of emclently removing liquid from the clothes and affording safety to the operator and is a continua.- tion of my application Serial No. 143,522, filed May19, 1937. Y I J 1 The general object of this invention has been to produce a multiple roll wringer employing preferably three rolls positioned in such manner that one-roll is common to the'other two and provides two roll bites therewith. Thus clothes are fed to the-wringer from side to side passing from one roll bite to the other. This 'wringer'is of tion Serial No. 143,522, This application November-27,

Thusythe rolliis not only adapted to be power driven but may shift up and down without breaking the driveconnecting it with th power head. i

Mechanism=is provided and becomes active 'on apredetermined separation between two of therolls to stop the operation of the wringer. My wringer thus operates in'generalin' such manner that. the initial orintake roll: bite employsa comparatively light pressure between the rolls and acts "not only to prevent the operator from feeding herwh'anids into thepressure roll bite, but serves to actuate a release which stops the wringer if her hands pass too far intothesame. More specific objects of my inventions-will .become apparent from the following description when construed in the light of the accompanying drawings and the important characteristics-are set out in the claims. i n In the annexed drawings: w Fig. 1 is a side elevation of my improvedclothes wringer; v 1-.

To this end the top roll. indicatedat dfl, is carried in the cover 20 and has secured to its shaft adjacent the head endagear adapted to mesh, with the gear, 31. These gears are .of'the construction'shown in Fig. 9. 'As illustrated in that figure each gear comprises two sets of teeth space between the teeth'of the other side. This enables the teeth to be circum'ferentially spaced a considerable distance-apart and thusthegears .Fig. 10 is a detail showing the cam. track ernv ployed in connection with the roll reversing mechanism.

The peculiartooth configuration of Fig. 9 also: facilitates" this separable driveby afiordingclearance between the contacting teeth. It will be noted by those skilled in the .art that these gears are fairly cornmoniin washing machines.

Theupper rollMl. as above stated, is the. roll shiftablycarriedagainst the pressurexof thepressure springs and the mountingoi this roll :is best shown .in Figs. 2 and-5. .Itwill there beseen that the top-20 embodies at. eachend thereof. a cross-rib 4,5 which, at its center, is shaped to form an upwardly opening slidewa'y 41 with yer.- tical'guiding 'ilibS' #8. r'I 'he two upper roll journal blocks 50 are carried in the said slidewaysfand guided therein by pinsriiz occupying theveritica'l opening, betweenzthe ribs -48. Downward mcwee ment of the "journal-blocks is limited by the underlying bottom-of. the pockets 41."

Nvringing: pressure: is applied againstthe' top' of the said journal blocks 50 by suitable spring pressure mechanism carried in the cover 20. As shown in Fig. 5, this comprises a pair of pressure springs 55 bearing at one end around a boss on the ribs 45, held in place by nuts 58 carrying washers 57 threaded to restrain bolts 60. These bolts slidably pass through the aforementioned bosses in the ribs 45 and terminateat their upper ends in yokes 62. Fulcrum bars 65 are pivotally carried in the yokes and bear at one end against the journal blocks 50 and at the other end against wear plates 61 integral with the ribs 45. Thus the tendency of the springs 55 to expand applies wringing pressure to the journal blocks 50 and through them to the roll. 40 carried therein in bushings 69.

The two lower rolls, coacting with the top roll 40, are indicated generally at I and I and are carried in the body portion I8. Each roll is seated at its ends in heavy bronze bushings I1, which in turn lie in slots of tieplates 80 at each end of the wringer and thus maintain the lower rolls in proper relation to each other. In the center of each tieplate is a slot '82, in which is slidably carried a guide 85, which as shown in Fig. 4 lies between the lower rolls, and which strips clothes therefrom and prevents their passage downwardly between the rolls, thus insuring feeding of the clothes properly through the wringer. The rolls I0 and T5 are normally retained upwardly either against the roll 40 or, if the top is open, against edges 86 of body cross-ribs 88 by four light springs 90 secured at one end to the plates 80 and at the other end to the said ribs 88. The springs are light enough to permit the feeding of an operators hand between the top roll and one of the lower rolls without harm to the same, although preferably this pressure is sufiicient to pinch the fingers enough to cause the operator to instinctively draw her hand-out of the roll bite. As indioated above, when the top is closed the rolls and I5 contact the top roll 40 and are positioned slightly below the upper edge '86 and thus the only purpose served by the upper edges 86 is to prevent excessive upward movement of the lower rolls when the top is opened.

Since the lower rolls would normally be free to move downwardly except for the light pressure of the springs 90, there would ordinarily be no wringing pressure set up by the two springs 55 acting against the top roll. My wringer is so constructed that either of the lower rolls desired may be forced upwardly against the roll 40 an retained fixedly in position to establish the requisite wringing pressure between that roll and the top roll. When so held the other lower roll is free to drop downwardly except for the light springs 90. When this condition is created the lower roll, locked in position, coacts with the top roll to establish the necessary wringing pressure through the medium of the springs 55 ancfthe other lower roll coacts with the top roll to provide a light pressure intake bite. It -is important that one of the lower rolls is locked against the upper roll it forces the same upwardly enough to push the top roll away from the bottom of the pockets 4'! and thus establish wringing pressure between the rolls before clothes are fed to the wringer. As will be hereinafter shown, the operating mechanism for the lower rolls just described may be shifted to enable either lower roll to operate as the auxiliary intake roll or as the second pressure roll.

A pair of cams 9'5 rotatably carried on a shaft I00 lock either lower roll desired in position as a pressure roll. The periphery of these'cams,

as shown for instance in Fig. 3, is substantially circular with a segment removed along a chord of the cam outer circle. It will be seen that the cam outer face departs from a true circle and tapers inwardly adjacent the cut-off portion as indicated between the arrows in Fig. 3 and marked X. The shaft I00 is journaled in members I02 and secured to the bottom of the body I8. At the end opposite the head the shaft I protrudes through the body wall and has mounted thereon a handle I05.

Either lower roll desired is forced upwardly against the roll 40 by swinging the handle I05 and with it the two cams either clockwise or counterclockwise, depending upon which lower roll is to be positioned. As shown in Fig. 3, the handle has been shifted clockwise and the lefthand tapered surface X of the cams 95 has forced the bushings 'I'! of the roll 75 upwardly to establish wringing pressure between thatroll and roll 40. It will be apparent from the figure that, due to the cut-out portions of the earns 95, the roll I0 is free to drop downwardly against the action of the springs 90. In similar manner, if the handle I05 were rotated counterclockwise the right-hand tapered surface X of the cam 95, Fig. 3, would underlie the bushings of the roll I0 and that roll would coact with the top roll to provide a pressure bite.

Latches are provided to abut the cams 95 in either of their active positions and retain the same locked. These latches are indicated at H0 and carried on lengthwise extending shafts Ii5 along both sides of the wringer. Each shaft carries two latches, thus providing a pair co-acting with each cam 95. The latches are normally urged upwardly in the position shown at the right-hand side of Fig. 3 by light shaft springs bearing at one end against the latch and at the other end against any convenient portion of the body I8. The upward movement of the latches is limited by mating abutments located at I I8 in the latch and rigid with the frame I8.

Steel pins are embedded in the cams 95 to contact the latches and maintain the cams in predetermined position. These pins are indicated at I 25 and are engaged by an inturned flange of the latches III), as best shown in Fig. 6. As shown in Fig. 3, the right-hand latch is locked behind the right-hand pin I20, maintaining the roll 15 in position to provide a pressure roll bite. At the same time the inturned flange of the lefthand latch IIO lies idly against the edge of the upstanding portion I22 and is inactive.

The latches I I0 may be manually depressed to permit rocking of the cams 95 to an inactive position, removing the pressure from the pressure rolls. To this end there is secured at the right-hand end of the shaft I00, Fig. 2, an upstanding arm I30, to which is attached a tension spring I35 carried at its other end in a pin I31 of the body I8. As shown in Fig. 6, when the cams 05 are in either active position the arm I30 is so positioned that the spring I35 is under'ten sion. Thus, whenthe latches IIO are rocked out of engagement with the coacting pins I20 the tendency of the spring to contract pulls the arm I30 upwardly and rocks the cams 95 to a neutral polslition, releasing the pressure from either lower ro The latches H0 may be manually depressed by the knobs I40 carried in the top 20. A stamping I45 connects each knob with each underlying pair of latches. This stamping, asshown'in Fig.

3, is'yoked atzthe top and bottom to pass beyond the shaftof the roll 40 andthe shaft I respe'c tively: The .sh'aftxI00 is annularly recessed-asshownin that figure to prevent, theloweren'd' of th stamping I45 from slipping 'sidewiseJThis construction is also shown in'Fig. 2. 'Ihe upper end 'of the stamping M is retain'ed from side-1 wise motion by theslot'and pin construction l ll,

I iii-which the pins are carried in "the; cross-ribs 88'. The knobs I40 are-retained lightly against one arm-oftheupper yoke of: the stamping I45 by light springsl50' sufli'oientto prevent rattling j of theparts andyet not sufficient to d'epressjthe latches I I0, againstwhich the lower arrns of, the

stamping I45 bear, It will thus be' seenthat as eitherfknoo Hilts-depressed it 'acts' through its" coa'cting stamping'ldli to depress one of the active latches holdirig' the"cam's-. '95 in -position. Since the' active 'latches"are'yconnected on the rock shaft I I both will rock simultaneously. Thus each' latch. 'drops out of;pos ition behind thef'pins' [-20 and underthe Jaction of-the spring'l35 the cams are returned to aneutralposition; relieving allwr'inging pressure from the rolls;

This armf-is connected by alink TI with the 'pin- IIll of the arm I65, Itthus follows that as the cam 95 is rocked suiiicientlyto'cause the pin I10 to traverse either portion marked A of th efsloti I60, the clutch 35, through the medium ofthe arm I and the link "I", willbe rocked fromfengagementjto in a-ctivefnositionan'd disconnect the clutch 321 from eitherIbevel gear {for 28; During travel of the, pinjI'I0 through the portionfB' of the ca m slot therefis no shiftingofthe clutch. i

(The 'me'chan'ismj just described is utilized to provide an automatiostop for" the wringer when the lower roll, acting as an intake roll, dro s'a predeterminedamount. "When this takes place an edge of the plates 80 contacts an inturned flanged top of adjacent latches I I0 and forces the same downwardly, dropping them from behind the pins I and enabling the cams 95 to be rotated by the spring I35. This rotation is stopped because the pin engaging-portion of the latches will abut a second set of pins I80carried in the cams 95, Fig. 7. The distance of travel permitted between the twosets of pins is sufiicient to enable the pin I10 to travel the length of either cam groove portion A and thus; as before described,

' stop the rotation of the wringer. I v

This is accomplished without relieving the pressure between the pressure, rolls because the cams do not rock far enough to cease contact may be either manual or automatic, acting to stop the roll rotation, and the second, which must be --manual,'to release the wringing pressure. It will be apparent that the construction shown may be a'daptedtofipermit an. automatic and simultaneous stopping "of the wringer with release of pressure. a

f I haveshown several minor features of my invention which .improve the operation thereof.

For"instance-,as 'shown in Figs. 2 and 6, I have placed.a;pulley" 2ll0 on each of the lower roll shaftsand connected the same by a resilient rubber beltr ,The purpose of this is to insure rotation'oftthe auxiliary roll through the more or lesspositivel-y driven pressure-r011 if there isany tendencyyofthe clothes to cause the aforesaid auxiliary roll to slip when they are fed thereto due to. the light pressure normally maintained at the auxiliary roll bite.

Stripper boards 2I0,' as shown in'Fig. 4, are

carried: on the latch shafts H5 and maintained by-lightsprings, notshown, against the lower rolls l0 and. I5: to strip clothes therefrom as they leav thewringer and prevent any tendency of Y the samegto wrap around the rolls. These boards are so shaped that they remainactive as either roll drops, under the impulse of-clothes fed thereto. Strippers 215 are provided, secured to the central top rib and functioningin like manner in conjunction with-the upper roll 40. Admin board or guide I00 is mounted on the shaft I00.

It will beseen from the foregoing description Y that I have invented a novel, efiicient andsa-fe clothes wringer v suchas described and now summarized in the claims. I

Other modes of applyingthe'principlegof' m l invention may be employed instead 'of' the one explained, change being made as regards the mechanism'gherein disclosed; provided the means stated .byfany ofthe following claims or the equivalent-of suchstated means be employed.
