This invention relates to clothes wringers of the type mounted on domestic washing machines and power driven by the washer mechanism. It has long beenrecognized in the art that rubber roll wringers of this type are-effective adjuncts to domestic washing machines because this auxiliary apparatus materially assists the washing process by compressing the fabric of the wet garments and flushing the soil out of the fabric.
In this connection it has been observed that repeated wringing of the garments results in furtherpexpulsion of the water and a decided increase in the cleansing actionof the wringer. This effect is noted even when abnormally high roll pressures are used, and is more pronounced when the clothes are struck, agitated, and rearranged between the wringings. It is believed that certain capillary action in relation to the fibers of the cloth, together with the natural sponge action of the compressed fabricslwhen leaving the pressure rolls, produces an effect which permits the further expulsion of water and soil and thus accounts for the increased drying and cleansing action. It is also believed that the original soapy wash water, with its affinity for soil,.retains the soil and thus the more elusive soil is expelled to produce better cleansing and drying. It will also be appreciated that in wringing garments of non-uniform cross section some portions of the garments, particularly the thicker sections, are wrung drier than others or thinner sections which escape the pressure from the bite of the rolls. With the multiple wringing of these garments this result is largely avoided and the garments are more uniformly and thoroughly wrung in all sections.
It is the particular object of this invention to provide automatically repeated wringing operations on clothes fabrics as they leave the washing machine in order to produce drier and cleaner clothes.
Another object is to provide multiple pairs of coacting pressure rolls with the pairs of rolls substantially separated from each other to permit sponge action of the fabric, and automatic means for conveying the garments through the succeeding pairs of rolls.
A further object is to provide in a wringer having multiple pairs of rolls separated from each other, means to loosen or to rearrange the garments as they are automatically conveyed between the pairs of rolls in order to provide in more uniform and thorough drying.
A. still further object is to provide wringer structure in a multiple pair roll wringer wherein the upper rolls are mounted in a frame which may be locked with the rolls in pressure relationship to the lower rolls or may be quickly separated from the lower rolls to provide a safe 5 wringer for both the operator and the clothes, as well as to expose the rolls and mechanism for cleaning and adjustments.
A still further object is to provide a removable drain pan for a multiple pair roll wringer 10 which will permit the wash water to be delivered back to the washer tub, or when used in a re- 'verse direction," to permit the' expelled water to be returned outside of the washer tub.
Other objects and benefits will be disclosed in i5 the following description and drawings in which: Fig. 1 is a broken elevational view of a conventional washing machine equipped with "my wringer having three pairs of pressure rolls;
Fig. 2 is a top plan view of the washer and 20 wringer as shown in Fig.1;

Fig. 10 is a similar view to Fig. 9 but showing the outer train of gears being driven;
Fig. 11 is an enlarged sectional view of my overriding clutch as it appears on the section line ll-ll of Fig. 8 and which will later be explained; and
a Fig. 12 is a longitudinal cross sectional view of an optional wringer structure which will later be explained.
Now referring to the drawings and at the outset particularly to Figs. 1, 2, and 3, I show a conventional domestic washing machine, indicating it generally by the letter A. Mounted on this 5 washing machine is a multiple pair wringer B which is driven by a reversible gear head C from the washer mechanism.
The mechanism is driven by a motor 5 through a conventional gear case l6 driving an agitator 10 I! in a tub l8. The same mechanism drives the wringer through the vertical wringer drive shaft 20 and the wringer support tube l9, as best shown in Fig. 3. The wringer gear head is pivotally and removably mounted on a pivot 15 2| and connects with the vertical drive shaft 28 by means of the stub shaft 22 and the drive pin 22' which connects with the drive slot 23 in the vertical drive shaft 20. The wringer is held in the position shown in Fig. 2 by the thumb screw I .20 24 which contacts the slot 25 in the stem 2|,
but the wringer may be turned 180 to extend sidewise of the tub l8 and is held in this position by the same thumb screw 24 in contact with the slot 25' as shown.
25 Now referring to Figs. 4, 5, and 6, I show a lower frame structure consisting of two side frame members 26 and 26' fixed in parallel relationship by the cross rod members 21 and 2'! and end shieldmembers 28 and 28. Mounted 30 in this lower frame structure are three lower rolls 3|, 32, and 33. These rolls are mounted in suitable bearings 34 of conventional form as partially shown in Figs. 6 and 8.
Mounted on this lower frame structure is an 35 upper frame consisting of two side frame members 35 and 35' similarly joined in parallel relationship by a top shield member 36 which is bolted to the side frames 35 and 35 by bolts 31' through ears 3!, as clearly shown in Fig. 4.
4 It will be noted that I provide in the upper central section of the member 36 a glass window 36' mounted in a conventional manner, thus providing an opportunity for the operator to see inside of my multiple roll wringer and observe 45 whether the garments are moving through properly. This structure is further stiffened by rod brace members 38 and 38, as shown in Fig. 4.
Swung at theends of the top frame member are two cam release bars 39 and 39'. These re- 50 lease bars have semi-circular cam slots 48 and 40 which mount in the cam slot plates 30 and 30', as shown in Fig. 5. This cam bar structure is Well known in the art and will not .be further described than to explain that when the 55 bars 39 are in substantially ertical position, as shown in dotted outline in Fig. 4, the cams will 'enter the slots in the plates 38 and 30, and by rotating the bars 180 the cam bars will draw the upper frame downward a distance equal to 0 approximately the diameter of the bars, thus providing means to draw the frames together and place the rolls in co-acting pressure relationship. By reverse movement of the bars 39 and 39' the cams are released from the plates 65 30 and 30 and thus the rolls are released from pressure relationship.
It will be understood and appreciated that by providing the cam bars 39 and 39, one at each end of my wringer, there is provided means 70 whereby the wringer may be released or reset from either end. This is important in a multi ple roll wringer of the type described where the wringer is of substantial width and where it may be operated from either end.
75 Mounted in the upper frame structure, as described, are three upper rolls 4|, 42, and 43.coacting with the lower rolls 3|, 32, and 33, respectively. Now referring to Fig. 7, I will describe the mounting of the roll 42. It will be observed that the trunnion of the roll 42 is carried in a .bearing 44 retained by a spring 46 in a bearing bracket 45. Now again referring to Fig. 4, the bearing bracket 45 is retained in substantially horizontal position by ribs 41 in the top frame members 35 and 35'. The bearing brackets 45 are carried by U-bolt 48 attached to the top frame by clamp plates 49. Compression springs 50 surround the legs of the U-bolt 48 and urge the roll 42 downward in pressure relationship with its companion lower roll 32. Similarly, the rolls 3|4| and 33-43 are mounted by similar structure to provide resilient means to hold the rolls in independent co-acting pressure relationship.
Now referring to Figs. 7 and 8, I will describe the gear train drive to the three pairs of coacting pressure rolls. Fixed in driving relationship to the central roll 32 is a spur gear 62. This spur gear 62, as shown in Fig. 8, is being driven by an internal gear 581 which is integral with an external gear 58X and, therefore, the gear 62 is merely clutched within the gear 58X. Immediately adjacent to its left and meshing with the gear 58X is an idler gear 60 meshing with a spur gear 6| on the trunnion of the roll 3|. On the opposite side of the roll 32 is an idler gear 64 meshing with the gear 63 on the trunnion shaft of the roll 33. It will be observed by the sizes of these gears that the roll 33 is driven faster than the roll 32 and that the roll 5 3| is driven slower than the roll 32.
Referring to Fig. 8, it will be observed that an outer train of gears is arranged to be driven through idler gears mounted on the off-center or eccentric studs 65 and 66. On the central roll 32 is an identical spur gear 12 to the spur gear 62 arranged to be clutched in the internal gear 581 integral With the external gear 53X. When the part 58 is shifted, as will later be explained, the gear 58X meshes on the left with the idler 10 which in turn drives the gear 1| on the roll 3|. On the opposite side the gear 58X drives the idler 14 meshing with the gear 13 on the roll 33..
It will be observed that when the rolls are driven in clockwise direction, as indicated by the arcuate arrows intersecting the numeral lines, that the roll 3| is driven faster than the roll 32 and the roll 32 faster than the roll 33. When the rolls are thus driven in clockwise direction, the clothes will be fed from left to right through the wringer or from the tub outwardly. Because the rolls are driven progressively slower, the clothes will be bulged or loosened as they progress from one pair of rolls to the next, and, therefore, 00 the fabric will be moved or rearranged, which provides means whereby the clothes are more effectively and more uniformly wrung. It will also be apparent that inasmuch as the rolls are driven progressively slower, there would be no chance of tearing the clothes by tensioning between the pairs of rolls.
When the wringer is reversed and the rolls driven counter-clockwise through the gears 60, 6|, 62, 63, and 64, the opposite effect will be produced-that is, the clothes will be fed from right to left and the roll 33 will be driven faster than the roll 32 and the roll 32 faster than the roll 3|.
Now referring to Figs. 6. 8, 9,'and 10, I will the shaft 22 by the pin 52.
is held continuously in mesh with a mating gear describe the reversible gear head drive to the gear trains. Referring first to Fig. 6, it will be appreciated that the stub shaft 22 is driven from the washer mechanism through the pin 22'. This stub shaft 22 drives a metal pinion 5| aflixed to The bevel gear 5| 53 fixed to a tubular clutch shaft 54 by the set screw 55.
As shown in Fig. 8, the tubular clutch shaft 54 is being driven through the bevel gears 5| and 55 and is in clutched engagement with the part 58 by its external clutch member 54C engaging the internal clutch 58C of the part 58. As shown in Fig. 8, the part 58 is now driving the inside numeral 68 series of gears by means of the integral internal gear 581 being in clutched engagement with the pinion 62 and driving the idlers 68 and 64 through the integral external gear 58X. Now referring to Fig. .10, I show the part 58 shifted inward so that the bevelgear 58B is now meshing with the gear 5| and is driving the numeral 18 series of gears by clutch engagement of the internal gear 581 with the pinion l2 and the integral external gear 58X in meshed relationship with the idler gears 18 and 14. Under these conditions the tubular clutch shaft 54. is out of engagement with the clutch 58C, and, therefore, the drive of the pinion 53 through the tubular clutch shaft 54 is nullified.
. Now referring to Fig. 9, I show the shifting element 58 in neutral position wherein the'internal gear 581 and the external gear 58X is positioned between the numeral 68 and numeral l8 train of gears and thereby all drive to the wringer is stopped. a
The shifting of the part 58 is accomplished by a conventional handle shifter mechanism, as shown in Fig. 6. The shifter mechanism has a yoke connection with the shifter part 58 and is actuated by the handle l6 in a conventional manner.
Now referring to Figs. 11 and 8, I show a conventional overriding clutch device generally designated by the letter 0. As shown in Fig. 11, the central section of this overriding clutch 81 is attached to the roll shafts by keys 61'. The internal clutch M has cam slots 89 where the internal surface of the cam is angularly arcuate to the internal recess diameter of the gear, and in these cam slots are placed short cam rollers 68. As is well understood in the art, when the gear is 'revolved in a clockwise direction, as shown in Fig. 11, the rollers 68 will be urged into driving engagement and the roll shaft will be revolved. However, if rotatiion of the gear is reversedythe rollers will be actuated in an opposite direction and the gear will revolve without rotating part 61 and the roll shaft.
Such overriding clutches are installed in the drive gears mounted on the roll shafts, namely 6|--'||, 62-12, and 63-|3. The cam slots in these clutches are arranged topermit overriding.
of the roll in the event that the clothes are being pulled faster than the normal drive speed of the rolls. The purpose of this arrangement is to avoid any possibility of tearing clothes by tensioning between the various pairs of rolls as they are fed through my wringer.
Now referring to Fig. 5, I will describe the means I provide to convey the clothes from one pair of rolls to the other while at the same time loosening and rearranging the fabrics for more effective wringing. Mounted on end bars 88 and 88 on the lower frame members 26 and 26' by the. bolts 8| is a series of stationary vertical support bars 82, 88, 84, 85, 88, 81, 88, and 89. On the end shield members 28 and 28' adjacent the rolls I aflix rubber guard members 28". On the stationary vertical members 82, 85, 86, and 89 I similarly aifix rubber guard members 82', 85', 86', and 88. It will be apparent that by this stationary structure I have provided means which substantially prevents the clothes falling below the tops of the stationary support members and have also provided structure which prevents the clothes being wrapped around the rolls.
As shown in Fig. 5, I provide rotatable crank arms'98 and 9| on which is mounted a connecting member 92 carrying vertical plate members 93, 94, 95, 96, 91, and 98, interposed between the stationary vertical members, as previously described. When the crank arms are revolved in clockwise direction, it will be obvious that the vertical plates 93-98 will be moved in a rotating movement, as indicated by the arrows, and the plates 93-98 will have the effect of striking, agitating andloosening the garments they contact while at the same time urging them forward through the wringer. It will be apparent that by this structure I have provided means to forcibly agitate, loosen and rearrange the garments to expel foreign matter from the fabric while conveying them through my wringer.
Now referring to Figs. 7 and 8, I show a thin spur gear |88 mounted on the shaft of the roll 32. This gear I88 meshes with idler gears |8l and I83 which drive the gears I82 and I84 which drive the crank arms 98 and 9|, as shown. This mechanism is entirely conventional and will not be further explained, it being understood that I have provided gear structure whereby my conveying mechanism is actuated as described.
From the foregoing description it will be understood and appreciated that garments may be wrung through my wringer in either direction with the wringer placed, as shown in Fig. 1, over the washing machine tub or revolved away from or outside of the washing machine tub. Under these conditions it is necessary to provide means to control the discharge of the expelled water and I now desire to explain my drain pan construction. Referring to the drawings and particularly to Figs. 4 and 6, I show a drain pan -l|8 extending completely under my wringer mechanism. This drain pan is held on the lower frame by means of the bead I I8 on the pan and the longitudinal recess HI and the lower frame members I26 and I26, as clearly shown in Fig. 6.
In the lowermost section of the pan I provide two drain cocks H2 and I I3. To either of these drain cocks may be attached a drain hose I I4. By this arrangement I provide means whereby the drain water may be returned either to the washer tub or to any outside destination as desired through the drain hose 4. As clearly shown in Fig. 4, I provide a rubber sealing member 5 extending over the wall section of the tub l8 to contact the drainpan H8, thus effectively sealing it as well as providing a protective resilient support for the pan. However, it will be appreciated that 'when the wringer is raised, as shown in Fig. 3,
the pan may be completely removed for cleaning both the pan and the under side of the wringer mechanism.
In the foregoing description I' have described a preferred embodiment of my invention, but it will be appreciated'that various other forms or designs are possible. For this reason I show in Fig. 12 an optional design of a wringer employing 'only two pairs of rolls with a slat chain conveyor device D between the two pairs of rolls., The structure, as shown in Fig. 12, is otherwise quite similar to the preferred embodiment of the invention described except that the rolls 32-42 are removed and the conveyor mechanism D inserted. Consideration of the conveyor device D, as shown, will reveal that such a device is practical not only to convey the clothes between the rolls but, owing to the peculiar action of the slats while travelling over the sprockets, the clothes will be agitated or loosened by the conveyor.
Various other designs are, of course, possible, and it will be understood that I do not desire to limit myself to the structure as shown except as such limitations are imposed by the following claims.
I claim:
