Application filed October 14, 1925. Serial No. 62,421.

My invention relates to an improvement in wringers, and in general my object is to provide awringer embodying a-power-operated roller and a spring-pressed roller arranged and related in a particular way to permit the wringer to be operated safelyand the goods to be released instantly from the wringer rollers, either by a back pull upon the goods, by tilting a part of the wringer frame by hand, or by operating a releasing lever. The present wringer is also mounted" to swing one hundred'and eighty degrees so that in one setting of the wringer the goods are fed away from the operator, and in vthe second setting toward the operator. However the wringer is also provided with means 'for reversing the direction of rotation of the rollers to permit the goods to feed away from, the operator in' either setting of the wringer.

In the accompanying drawings, Fig. 1 is a side elevation of my. improved wringer mounted upon a portion of a tub orwashmg machine. Fig. 2 is an end elevation of the wringer. Fig. 3 is an end elevational and vertical section on line 33 of Fig. 1. Fig. 4

is a horizontal section of a art of the wring-I er on line 44 ofFig. 1. igs. 5 and 6, are similar diagrammatic views, showing the rollers set for release under reverse rotatable conditions.- Fig. 7 is a vertical section 'longitudinally through the .wringer. Figs. 8 and 9 are similar enlarged'cross-sections of the wringer in working and releasing position, respectively, when feeding goods to the wringer from the right.

In power-operated washing machines it is a a common practice-to mount a wringer'A in a swinging position upon an upright post B fixed to or forming'part of a washing recep- "tacle C, and it is alsmquite common to employ a power-transmitting shaft 1), three bevel gears E, and -av shifting clutch F to control the operation of thegears and a pair of rubber covered wringing rollers GandH journaled in the wringer frame. In'.addi-.

tion to such devices the present machine comprises a main frame 2 having perforated j arms or posts 3-3 extending verticallyaat its .opposite ends within which a pair of pivot members ortrunnions 4-4 are rotatably seated tosupport a secondaryframeor yoke 5 in a suspensory tilting position thereon. Yoke 5 is a hollow casting having downwardly flaring sides and an open bottom adapted to house upper roller H, and the depending legs 6 of the yoke are ribbed or grooved internally at 7 to confine and guide the journal members or collars 8 for shaft 9 of said roller. Cross pins 10 in legs 6 limit thedownward movement of the j ournal members 8, and a bowspring 11 within hollow yoke 5 presses said journal members I ,8 and roller H downwardly at all times. i A

tension screw 12 centrally at the top of yoke '5 bears against the middle of-spring 11, and

this screw may be adjusted to increase or decrease the pressure on the goods passing between the two rollerswhen in rolling contact one above the other. However, the two rollers are not aligned in the same perpendicular plane, but preferablyv with the upper roller offset in slight degree with respect to the lower roller in order that the tension of the bow spring may be utilized to hold or look upper roller H at one side of the crest of lower roller G toward the delivery side of the wringer substantially as delineated in Fig. 8. In that case pull on the goods will cause theupper roller to ride over the crest of the lower roller, thereby automatically relieving the upper roller from pressure engagement with the lower roller. -However, a stop pin 14 carried by the main frame post 3 will limit the outward movement of the yoke providing this stop pin is projected into a short curved slot 15 1n one end of the yoke. The same stop pin and slot will limit the movement of the yoke inwardly, thus definitely fixing-the offset working position of the upper roller'with respect to the lower roller when'the latter is rotating in a given direction to feed the goods into the bite of the rollers. But when conditions demand that the goods be fed .from" the opposite side of the wringer and the direction of rotation of therollers is reversed, a different setting must be established vfor stoppingthe movement-1 of the yoke because the yoke must now be tilted in the opposite direction to release the goods of alternatively. To efl'ect the entrance of one stop member while withdrawing the other from slot 15 I pivot a single rocking lever-17 upon upright arm 3 opposite slot 15 and connect the two pins to opposite ends of the lever, see Fig. 4. The stop pins may be round pins of a suitable length to protrude through openings in arm 3 and the pins may be of the same length so that when the lever is placed in a neutral position neither pin will project into slot 15; but, if the lever is tilted to either side of its pivot only one pin will project into the slot.and act as a stop in co-operation with the closed ends of the slot. Thus, if the direction of rotation of the rollers is such that the goods may be fed intothe wringer from the right.

as shown in Figs. 8 and 9, stop pin 14 will limit the tilt of yoke 5 in both directions; first, to establish the slightly offset working relation of the rollers as shown in Fig. 8, and second, 'to limit the outward swing of the yoke when the yoke is tilted to release the goods. Such titlting may be caused by pulling on the goods or by applying hand pressure laterally against tension screw 12. -An alternative offers itself to separate the rollers in an emergency, or to release the goods from the bite of the rollers, say if the goods are too frail to risk a back pull, and that is, to shift lever 17 into a neutral position, or even beyond that point, so as to withdraw stop pin 14 from the slot. The yoke would then swing to the left or delivery side of the wringer auton'iatically becase bow spring 11 will cause the upper roller H to ride down the left side of lower roller G due to the offset relation of the rollers as determined or first set by pin 14:.

Exactly the same'rcleasing results can be obtained when the rollers are set to feed the goods from the left .side of the wringer, but in that case the first pin 14 is withdrawn from the slot aud't-he second pin 16 is entered to serve as a stop and to limit the tilt of yoke 5 in opposite directions, first, to lock the rollers in offset working relation, and second, to limit the swinging movement in freeing the goods from the grip of the rollers. Again there are times when it is desirable to invert the yoke completely to permit the rollers to be inspected, cleaned or removed; and this result may be obtained by placing lever 17 in a neutral position or oscillating it .to withdraw the particular stop pin which is being used at that time to limit the outward swing of the yoke.

In setting the wringer for use the mere pressure of the hand against either depending leg 6 of the pivoted section or yoke 5 causes the upper roller to ride over the crest of the lower roller into a self-locking wringing position, and this otfset working relation of the rollers may be eflected still more easily when the lower driving roller is being rotated in the proper direction by power. As shown tl1e 'rollers are only partly exposed to ermit the goods to be fed readily into the bite of the rollers, and inclined guards or flanges 18 extend on opposite sides of main section 2 to assist in feeding and discharging the goods to and from the rollers. A bottom connecting piece 19 for wringer section 2 may also be provided to support a drain board 20 in a shiftable position-beneath the rollers, and this connecting piece may be angular in cross section or slope downwardly in opposite directions to permit the drain board to be supported, alterna- 'tively, on opposite sides of the wringer in reversely inclined positions lVhat I claim, is:

1. A wringer, comprising a power roller and a second roller yieldably engaged therewith, a movable support for said second roller adapted to shift said roller across the crown of said power roller, and means adapted to limit the movement of said support and place said yieldable roller in a feeding position at one side of the crown of said power roller but free to ride reversely across said crown at all times to separate said rollers.

2. A wringer, comprising a pair of coacting rollers, one "of which is pivoted to swing beyondaplane extending on astraight line between its pivot and the axis of the other roller, means adapted to limit the movement of said swinging roller in one (llrection to hold it in a slightly offset position in respect to the other roller, and means adapted to press said rollers yieldingly togcther, both said limiting and pressing means permitting a swinging movement in an opposite direction and free separation of the rollers at all times.

3. A wringer, comprising a pair of coacting rollers, a swinging support for one of the rollers, and means arranged to limit the movement in one direction of said swinging support and the roller mounted therein to permit self-locking and unlocking engagement with the companion roller, said means permitting free movement of said support and roller in an opposite direction.

4. A wringer, comprising a pair of cooperating wringing rollers, and a movable support for one roller and stops therefor adapted to permit one roller to be placed in a locked swinging engaging position with the other roller at either side of its horizontal axis and to be separated therefrom in either position by a movement across said axis.

5. A wringer having reversible wringing rollers, a shiftablc support for one roller adapted to shift said roller to alternative operating positions at opposite sides of the lower roller and said support being always free to shift reverscly to disengage said rollers.

6. A wringer, comprising a power roller and a friction roller,- a swinging support port carrying one of the rollers, said support being shiftable and combined with means adapted to permit the roller thereon to be placed in a locked wringing and self-releaseing position against the other roller on either side of a plane extending on a straight line through the axis of the other roller and the pivot of said support, whereby the goodsmay be fed into the biteof the rollers from" opposite directions alternatively as set and permit the goods to be released from the bite of the rollers and the rollers separated by pulling on the goods in an opposite direction to the feed movement of thegoods.

8. A wringer having a power-operated roller'and an idle roller, said idle roller having a movable support adapted to shift the idle roller to opposite sides of the power roller, and a pair of stop members ada tedto be used'alternatively to limit the swing ing movement of said support and idle roller in op osite directions.

9. wringer comprising a power roller, a second roller movable to difi'erent wringing positions on opposite sides of said power roller, and a tilting lever having spaced stopping devices adapted to fit the two wringing positions of said second roller.

10. A Wringer frame-having a reversible power roller journaled therein, a second roller and a swinging suppor-t therefor u 11 said frame having a slot therein," and u shiftable device on said frame having stops spaced apart and co-operatingwith the ends ,of the slot in said swinging support to stop 45 its swinging movement in one direction and permit free movement in the opposite direction. v

In testimony whereof I afiix my si nature.
