15 Claims.

The invention relates to wringers and particularly to those used in connection with domestic laundry machines.

A general object of theinvention is to provide y a new and improved wringer structure having high operating emciency, simple control mechanism, and an eiective and responsive means for quickly releasing the rolls from their cooperative relationship.'

Another object, is to provide a new and iinproved wringer in which the wringer rolls are supported for relative movement into and out of operating contact by means arranged to permit relative movement of the rolls in a combined lateral and rectilinear direction with respect to the plane of the rolls when cooperatively engaged.

More specifically stated, another object is to provide, in a Wringer having a roll supporting head pivotally mounted for swinging movement from a central operative position, improved means for establishing operative engagement between the' roll carriedA by the head and a fixed rollwhich includes means for shiiting the pivotal axis of the head to move the roll carried thereby ,bodily` into engagement with the fixed roll, and quickly releasable latch means for maintaining the rolls against a shifting and swinging release movement.` f

In conjunction with the foregoing, other-fob- :lects reside in the provision of novel means for latching the rolls in operative relation, for hold. y

and scope of the invention 'as expressed in the appended claims.

In general,V the exemplary form of wringer structure embodies a frame comprised of a fixed or base section 20 (Fig. 1) having spaced upstanding end members 2 I, 22 arranged to support therebetween a head or movable section 23.

VThese frame sections 20, 2 3 each support one of a pair of cooperating wringer rolls 24, 25 respectively. 'T'he present wringer is of the type in which the head section is supported for swinging movement with respectto the base section, this movement being effective to carry the upper wringer roll to either side of a central or intermediate position in which the rolls are alined in a vertical plane. e

In such a wringer the present invention provides means for supporting the head for rectilinear movement in addition to the swinging movement for the purpose of shifting the upper wringer roll into operative engagement with the lower roll while placing the rolls under yielding pressure. This means may desirably be actuated by the same manipulable member which is pro-` vided for shifting the reversing clutch of the -ro1l Fig. 8 is a fragmentary view of the drain pan 55 driving means. The structure includes latching the form of hollow castings having inner flatfaces to which bearing brackets 26 and 2l respectively are fixedly secured as by screws 26.

The brackets are the Width of the associated castings and extend above and below the lower wringer roll 24. A spacer bar 29 extends be-- tween and is rigidly secured to the lower portions of the brackets 26, 21 to ,complete the base section assembly. Each ofthe brackets 26, 2l has an upwardly opening, centrally located pocket 30 to receive bearings 3| for the shaft 32 of the lower wringer roll 24, the end walls-of the brackets being slotted, as at 32, to permit the shaft ends to extend beyond the brackets.

The head 23 is a channel-shaped casting longitudinally dimensioned to extend between the end members 2| 22. At its ends, the head has depending arms 33 which include integrally formed end walls 34, 35 facing respectively the inner faces of the end members 2|, 22. The arms extend downwardly substantially to the upper edges of the brackets 26.21 and the lower side edge portions thereof are slightly inturned, as indicated at 36 (Fig. '4). The side walls of the brackets 26, 2, which in assembly are opposed to the inturned portions 36 of the arms 33, are outwardly offset, as indicated at 31, to receive the extremitiesof the arms therebetween as shown in Fig. 3. This telescoping relationship is used to maintain the frame sectlonsin vertical alinement and to restrain' the head section against swinging Vmovement to either side of the base section.

For supporting the head, a shaft 36 has its ends 38a pivoted in bosses 3 9, 40 in the end members 2|, 22, respectively. Between its ends, the shaft is offset, as may be seen in Fig. l, to provde alongitudinal central crank portion upon which the head 23 is rotatably mounted by bearings lil, i2 on the end walls 34, 35 of the head. The shaft 38 thus supports the head for swinging movement relative to lthe base section and rotation of the shaft produces a vertical shifting movement of the head. The extent of oiset or throw of the crank is suicient to shift the head between an elevated position in which the arms will clear the brackets 26, 2l on the base section and a lowered position in which the arms are held between the upper portions 3l of the brackets 26, 2l. A pin 34a on the end wall 34, extending endwise therefrom, may be used to limit the swinging movement of the head.

The upper roll 25 is supported for sliding movement longitudinally of the arms 33. With reference to Figs. l, 4 and 5, the ends of the upper roll shaft A3 are journaled in bearings d which are seated in downwardly opening pockets in movable bearing supports t5. The supports include integral end plates 46 of substantial size The engagebosses' 49 on' the head and by other means to be presently described. These plates prevent outward movement of the upper roll and its bearings from the bearing supports.

Extending from each side of the bearing supports areears 50 which are apertured to provide seats for the heads of bolts 5| extending inwardly of the arms along opposite sides thereof. The upper or inner ends of the bolts carry nuts 52 and compression springs 53 bear between the `nuts and the ears 50. The upper or inner ends of the bolts beyond the nuts are seated loosely in recesses provided in the bosses dit The parts are so arranged that the springs are not compressed, except when the upper wringer roll has been moved into operative engagement with the lower wringer roll byinward vertical shifting movement of the head.

'When the wringer isV not in operative condition, the head is elevated with respect to the frame, in which position the head is freely swingable to either side of the central position in which the frame sections and the wringer rolls are alined. The Wringer is placed inoperative condition by rotation of the shaft 38 to move the head inwardly of the base section, by whichA movement the rolls 24, 25 are brought into operative contact and the upper roll is caused to shift inwardlyof the arms 33 to compress the springs 53. Quickly releasable means may be conveniently associated with the shaft 38 to latch the frame sections and the rolls in their cooperating relationship. Moreover, the same actuator which is manipulable by the user to rotate the shaft and condition the wringer for operation may also be utilized to control the drive for the wringer rolls. These relationships are, in the present instance, embodied in the following construction.

Referring to Figs. 1 and 9 particularly. the end member 22 is somewhat larger than the opposite end member 2| and, for convenience in the assembly of parts, has a detachable end plate 22e sealed thereto against an interposed gasket. The end member 22 has a vertical transverse partition 54 between and parallel to its inner and outer faces. horizontal, longitudinally extending bearing 55 for an actuator shaft 56 dimensioned to extend outwardly through and beyond the plate 22a to receive a hand lever 51. The end of the shaft 56 extends beyond the inner face of the partition 5t and has a crank plate 58 rigidly aiiixcd thereto and extending laterally thereof.

A pair of spaced antifriction rolls 56, 66 are mounted on the crank plate 58 in eccentric relal tion tothe shaft 56, and these rollers are adapted for engagement respectively with inturned iianges 6|, 62 (Fig. 9) formed on the side and adjacent'to the freely swinging end of a toggle plate 63. lThis plate is supported near its lower end by a pivot 64 on the partition 56 for movement on a horizontal axis in a plane parallel to the partition. Near its upper end, the toggle plate 63 is pivotally connected, as at 65, with a toggle link 66 which, in turn, ispivoted, as at 67, to the outer endof an arm 68. The arm isr rigidly connected, as at 69 (Fig. l), with the offset portion of the crank shaft 38.

Between the ange 62 and the pivot 64, the

Near its upper end the partition has a inthe-flange v18, anda spring 15 bearing between the head' and the flange holds the head in its associated recess. The springv also urges the toggle plate 88,'together with the parts associated axis. The-head 'l2v and its receiving recessy .are

the pivot and bears .against the side face of the trigger 88.-,-v The tension of the spring88 normally urges the trigger into a center position determined by its flatwise abutment with-the flange shaped to permit free rocking movement of the Pin.

The relationship of the partsis as follows. reference being had to Figs. 9 and 11. When 'the wringer is in its inoperative condition with the head in its elevated position, and the wringer rolls separated, the operating parts are urged by the spring 15 generally into the position shown in Fig. 11. In this position, the toggle plate 63 is swung to dispose the'- flanges 8| and 82 in engagement with the rollers 459, E8 respectively.

4The crank. shaft`88 has been swung by the extended arm 88 and toggle link 88 to a position in which the head is elevated with respect to the base section of the frame. Manipulation of the hand lever 51, to rotate the shaft'58 in either direction, will move the head inwardly of the frame. Thus, rotation of the shaft 58 in a clockwise direction will, through the engagement between the roller 68 and flange 82, swing the toggle plate 88 in a countercloclrwise direction, closing the toggle and imparting clockwise rotation to 'I the crank shaft 38 to move the offset portion thereof to: its lowermost position. if' the shaft 58 is rotated in a counterclockwise direction, the same result obtains, except that the toggle plate 88 is moved by engagement of the roller 59 and flange 8i.

When the plate 88 has been swung to the limit of itsmovement, as determined by engagement between the flange 8l and a stop pin 16, the

parts will occupy substantialiy the position shown .I

in 9, in which the offset portion of the crank shaft 88 extends downwardly and the head occupies its innermost position. As this setting operation takes place, the spring 15 becomes additionally Vstressed or-compressed and the force is available to shift the head to its elevated position. Incidentally, the return movement of the parts to their released position, as shown in Fig.

11, may be limited by such means as a finger 1'1` extending from the arm 88 for engagement with a stop pin 18.

A preferred form of quick release means for maintaining the wringer assembly in operative condition is best shown in Figs. 1, 3, 13, 14 and 15. For convenience in assembly, the crank shaft l38 is preferably formed in end-to-end sections which 'are suitably joined rigidly together by such means as a pair of semi-cylindrical coupling membersl 19 (Figs. '1 and 13). -One' of the members has a radially extending end portion 88 which terminates in an axially parallel linger 8| having an angular comming side and an. opposite flat engaging face as best shown in Fig. 1. The preferred assembly locates thisflnger approximately midway between the ends of the head. A pair of longitudinally spaced bosses 82, 83 extend downwardly from the head'to support a plate 84 having a longitudinally extending side flange 85 turned. toward the head. A trigger 88 is supported by a pivot 81. from the flange 85 to extend therefrom toward the open face of the head and past the plane of movement of the finger 8|. A leaf spring 88 (Fig. 13), secured to the flange 88 at a point spaced from the trigger pivot 81, has a bifurcated end which straddles LLI 85; `as shown-in .Figr 14,- but permitsrjheftri'ggen plane ofthe-flange, oritransversely of the head...

A coil-spring, 89, connected to the trigger and to a finger 98 projecting outwardly in the plane of the flange 85, exerts a tension which swings the trigger in the direction of the latching finger 8|. As shown in Fig. 6, the trigger 8G has a notch 9| arranged to provide a shoulder 92 for engagement by. the flat face of the latching finger 8| when the finger has rotated with the crank shaft to a position in which the wringer head is in its innermost position. Since the latching finger 8| always approaches this position of engagement from the 'same direction, a portion of the trigger immediately above the shoulder 92 is cutaway to form a camming surface 98 over which the camming` side .ofthe latching finger may ride into Aengagement with the shoulder, and in doing so swing the trigger out of its path. The cut-away portion which forms the surface 93 is of sufficient size to permit the finger to pass the trigger when the trigger is swung to a position between the finger and the shaft 38.

The trigger is normally held in position for engagement bythe finger 8| by means which is also operable to shift the trigger transversely to release its holding engagement with -the finger. This means is arranged for convenient actuation from either side of the wrnger head by the user in an emergency. Thus, each side of the' wringer head supports a release bar 94 which is shaped to follow the contour of and ft within the opening formed by the Vside edges of the head and the depending arms 33, as may be seen clearly in Fig. 2. The release bars are mounted for swingingv movementrrelative to the head by such means as ears 95 (see Fig. 5 particularly) which are engageableby smooth ends on selfthe ends of the screws extend through the guard plates I8 to restrain these plates against movement outwardly of the arms.

The horizontal portions of the release bars are inwardly facing channel-shaped members (Fig. 14), and, as shown in Fig. 13, have a pair of longitudinally spaced, inwardly extending, transverse flanges 91, 98. The opposed release bars are connected-by a loosely supported release plate 99 (Figs. 13 and 14) which extends on a horizontal plane between, and is connected with, the two pairs of flanges 91, 98 by such means as projections |88 on the plate engaging apertures ||l| in the flanges 91 and ears |82 at the opposite ends of the plate disposed in notches |83 in the flanges Y98. To prevent accidental disengagement of the parts. it is preferred that the plate 99 be held against withdrawal from at least one of the flanges as, for example, by a pin |84 carried by a flange 98 and extending through an ear |82.

As shown 'in Fig. 14, the release plate 89 has a slot |85 adapted loosely to receive the lower end of the trigger 88. is longer than the width of the trigger and the' slot 1s preferably arranged so that the trigger, when disengaged from the finger 8|, will be swung by the spring 89 into a position in which the cam surface 93 is squarely in position for engagement by the finger 8| as the shaft 38 isvro- The length of the slot `tated to effect operative association of the rolls.

' release bar relative to the head.

The operation of the latching mechanism is as follows: As the shaft 38 is rotated to depress the head and engage the wringer rolls, the finger 8| engages the cam surface 93 to swing the trigger about its horizontal axis. Substantially as the head reaches itsinnermost position, the finger 8| enters the trigger notch 9|, the engagement being assured by the spring 89. When the rotating forceapplied to the shaft 38 by the user is released, thefinger 8| engages the shoulder 92 to latch the head in its innermost position. The parts then assume the relationship seen best in Fig. 14. Should an emergency arise, the user strikes or presses inwardly on either of the releasebars 94, which shifts'the release plate 99 and the trigger 88 transversely in one direction or the other,l thus releasing the engagement between the nger 8| and the shoulder 92. The force exerted on the shifting mechanism by the tensioning springs 53 and by the toggle spring instantly rotates the shaft 38 to its original position, thereby elevating Vthe head and freeing the arms 33 from their interengaging position between the offset portion-s 31 of the brackets 26, 21, to release'the head for swinging movement in either direction. The position assumed bythe parts upon inward movement of a release bar may be seen in Fig. 15. The release bars are returned to their normal position (shown in Fig. 14) by the centering force exerted thereon by the spring 88 through the trigger 86 and release plate 99.

It is to be noted that the latching mechanism is relatively quite sensitive, since the trigger 816 and finger 8| engage with an edge-to-edge relationship. Hence it is only necessary to move the trigger transversely through a distance slightly greater than its thickness to effect the' disengagement. Moreover, the parts are so related that the resulting leverage system permits the shaft 38 to be held by the application of a relatively light force requiring little effort on the part of the user to overcome.

Since the position of the trigger with respect to the path ofmovement of the finger 8| is rather critical, the original position of the trigger may be conveniently adjusted as follows: One end of the trigger supporting plate 84 is lof substantial width as indicated at |01 in Fig. 13. The boss 83 which underlies this end of the plate is correspondingly dimensioned (see Fig. 3). Screws |08 secure the plate 84 to 'the bosses 82 and 83 on the longitudinal center line of the plate. vOn either side of the screw |08 at the A wide end of the plate, the boss carries headed screws |09 (Fig. 3) which underlie the plate and provide adjustable abutments for determining the plane of the plate relative to the head and the transverse position of the outwardly extending trigger. Intermediate support for the shaft 38 may be provided by a lug ||0 rigid with the head and arcuately recessed tofreceive the shaft.

The drive for the wringer rolls is, in the `presable wringer drive shaft (not shown) adapted for sliding engagement with an axial opening I I3 in the coupling. Pinned to the coupling and extending axially upward of the post is a shaft H4 which immediately above the coupling, and at its upper end, has gears ||5, ||6 respectively affixed rigidly thereto. The upper gear H6 is disposed in a slidable bearing H1 formed on the partition 54. The lower wringer roll shaft 32 extends through its bearing and the associated bracket into theend member 22, and is connected through a universal coupling i i8 with a gear ||9 journaled, as at |20, von the partition 54 and disposed for selective engagement with the gears H5, H6. A yoke 92| has spaced ends surrounding the shaft H4 adjacent to the gears H5 and H6, and the base portion ofthe yoke is pivotally connected, as at |22, with one end of a yoke shifting link |23. The other end of the link |23 is pivoted eccentrically,fas at |26 (Fig. 10), to a disk |25 which is rigidly connected to the shaft '56 adjacent to the end of its bearing 55. The arrangement is such that when the shaft 56 is swung by the hand lever 51 in one direction, for instance in a clockwise direction looking atvFig. 10, the gears H5 and H6 lare shifted upwardly to carry the gear IE5 into engagement with the gear H9. Opposite movement of the hand lever-51 effects` engagement between theA gears I |6 and H9. Thus, if the wringer is in an inoperative condition, movement of the hand lever 51 to establish driven movement of the rolls in a desired direction will also be effecent embodiment, controlled by the hand lever 51. The wringer drive, as shown in Figs. 1 and 10, embodies a coupling shiftably and rotatably housed in a vertical post ||2 formed on the end section 22, and by which the wringer is convenientlysupported. Power to drive `the wringer is transmitted to the coupling by al suittive to condition the wringer for. operation, the shaft 38 being rotated in the same direction regardless of the direction of movement of the hand lever 51. After the wringer has been latched in its operative condition, the hand lever may be returned to neutral to stop the roll drive, or moved toits opposite position to drive the rolls 1n a reverse direction without disturbing the operative condition of the wringer.

1f the quick release mechanism is actuated while the wringer rolls are being driven, the driving connection will be interrupted by return of the clutch mechanism to its neutral position. This results from the fact that when the hand lever 51 and its shaft 56 have been rotated to establish a driving connection 'through the clutch, one or the other of the antifriction rollers 59 or 66 is located immediately adjacent to its associated ange 6| or 62 on the toggle plate 63. Upon actuation of the quick release mechanism, the swinging movement of the toggle 'plunger |26 (Fig. 12) seated in an axially parallel bore |21 in the bearing 55 and urged outwardlyby a spring |28 for engagement with any one of a series of properly located recesses |29 in the disk i26.

The present wringer structure embodies a positive and efficiently acting drain pan assembly for shifting the drain pan properly in accordance with the driven movement of the wringer rolls. A drain pan |30 (Fig. 1), arranged to extend a substantial distance beyond either side of the wrmger frame, is pivotally supported on the base section beneath the lower roll. 'I'he support at one end comprises a pin |3| carried by the bracket 21. At its other end, the drain pan is mounted on the longer end of a U-shaped shift- 2,288,847 ing lever lsz'which is journaled in and extends through the-bracket 26. The end wall of the drain pan has an outturned nib |33 (Fig. 4) disposed oneither side of the lever |32 for engagemenisby a pin |34 xed to the lever so that rocking mbyement of the lever will tip the drainv pan in one direction or the other. .The end of the lower wringer roll shaft, which extends through and beyond its bearing and support, carries a loosely fitting collar |35, the peripheral surface of which is angular to provide a seat for the hub of a shifting member |38 having radial fingers |31 (Fig. 8) extending therefrom. The nngers are arranged to engage the shorter end of the lever |32. In opposition to theside faces of the collar and encircling hub are friction disks |38, each of which is xed for rotation with the shaft 32 by connection with a pin |39 carried by frame, is resisted by the interengaging relationship of the head and base sections. When the wringer rolls are latched in operative relation, the hand lever 51 may be manipulated as desired to establish either driving connection or to stop roll movement. If the safety release mechanism is actuated while the wringer is in operation, the

- clutch mechanism is shifted to its neutral posithe shaft. A spring |4|l` (Fig. 8) is interposed between one of the pins |39 and the friction disk adjacent thereto to exert a force for holdixigthe-plvll friction disks in close abutment with'the sleeve accordingly.

The lower portion of the lower roll and the brackets and 2l are preferably concealed by feed boards IM which are assembled on the wringer frame inka simple and convenient manner. In this embodiment, each feed boardis a unitary casting arranged, as shown in'Figs. 2

' and 3, to cover the lowery portion of the wringer tion and the vhead is freed to move upwardly and to swing to either side of the frame. This combined movement of the u pper wringer roll provides an unusually large clearance between the disengaged rolls, yet there is no possibility that the user may be injured by the movement of the head immediately upon release thereof.

I claim as my inventionz' l. A wringer comprising, in combination.- a

I said head toward said frame and effect operative and extend for a substantial distance beyond each side of the base section. Each side portion of the feed board extends upwardly, as at Mie, in concealing relation to the brackets 2li and 21, and the upper edge of each of said portions terminates in a. downwardly extending lip |42 (Fig. 3) arranged to hook over the upper edge of the oilset 31 on the bracket. Near the bottom of each side of the brackets, an ear |43 extends outwardly to be adjacent to the innery faceof the side wall |44 of the feed board. The ears carry vadjacent to-each outer edge of the drain pan.

From lthe foregoing, it will be evident that a I -I ,novel wringer .structure has been provided which ,simple in construction, emcient in operation,

and possesses a high factor of safety for the prolfectionv of the user.` In order to condition the wringer for operation, it is only necessary for theuser to swing the hand lever 5l in one direction `or the other according to the direction in which the rolls are to be driven.
