` (ci. fis-245) i 3 Claims.

This invention relates to a wringer which is designed for use in connection with clothes washing machines and more particularly with a small type household utility model lcapable of being stored in relatively small quarters while-not in use. In this connection, the wringer is so constructed and mounted asvto provide a disappearing wringer capable of moving about its mountings on the washing machine tub so that the wringer may be turned over into the tub proper of the machine whereby the overall dimensions of the washing machine are directly determined by the overall dimensions of the tub of the machine itself.

It is one of the main objects of the present washing machine and the disappearing wringer structure to provide such a wringer which is ca'- pable of moving into and out of the tub proper of the washing machine and wherein the wringer is constructed as to provide a portion of the closure of the upper end of the washing machine tub when disposed in operative position and also when disposed within the tub and out of operative wringing position.

Another object of the present invention is to provide a cover for the wash machine which cooperates with the wringer and tub to form a closure means for covering the remainder of the open tub portion when the wringer is disposed in inoperative position within the tube, and such cover also provides the closure means between the wringer portion of the top of the tub enclosing the balance of the opening when the wringer is upper peripheral edges of the tub walls. This cooperative cover means also provides a tray which can be displaced from the tub closing position to a position adjacent the clothes discharging side of the wringer where it is operatively retained by cooperative means formed on the wringer while the tray rests upon the upper edge of the one of the tub walls to extend outwardly from the tub proper thus forming a removable tray which receives the clothes as the latter are expelled from the wringer.

Another object of the present invention is to provide the simplified wringer structure with suitable latch means which will automatically hold the wringer in raised and operative relation with respect to the tub of the washing machine when the latch means is manually operated. As an additional feature, the base of the wringer itself is arranged and designed to support such latch means in a position to coact with a portion disposed in operative wringing position above the of the washing machine tub with a portion ofthe base of the wringer automatically engaging' a' pori tion of the tub whenever the wringer is disposed out of operative position and Within the tub posi- -tioning the wringer in inverted and housed relation. When the wringer is so inverted and so held, the base portion thereof forms a part of the closure means ofthe tub per se.

A further object of the present invention is to providea manually operable handle for ro-4 tating the wringer rolls which is connected with the shaft of the drive roll in such a manner so that it may be released, rotated and folded into a position alongside of the wringer rolls so that this handlewill also be capable of movement into the tub together with the wringer whenever the latter is being inverted and nested within the walls of the tub proper of the washing machine.

All other objects and advantages inherently relating to the particular design and construction of the washing machine with the feature of the disappearing wringer shall hereinafter appear in the following detailed description relating to a preferred embodiment thereof and referring directly to the drawings disclosing such embodiment and forming a part of this specification.

In the drawings:

Fig. 4 is an end elevational view of the wringer structure and washer combination with certain portions thereof in section substantially as viewed along the line 4-4 in Fig. 2; and

Fig. 5 illustrates a fragmentary portion of Fig. 4 with the wringer rotated into nested and inoperative position within the upper portion of the washer tub and with the tray being removed and replaced to provide a cover for the open portion of the tub when the wringer is in the posi"- tion shown.

Any type of clothes wringer may be utilized in combination with the tub of a washing machine in carrying out the inherent principles of the present invention. The wringer in the construe:

aai-

tion disclosed in generally indicated at I and is conveniently secured and supported by a base 2, such base providing a flat under surface 3 having upstanding flanges 4 and 5 which terminate in beaded edges 6 land 1, respectively. In this manner, the base 2 constitutes a longitudinal trough extending the length of the wringer structure and substantially from wall to wall in the tub to provide a spillway for the water and suds which are pressed out of the clothes that pass through the wringer thereby causing such water to be directed and discharged adjacent the

walls

8 and 9 of the washing machine tub I0 as seen in Fig. 2.

The disclosed wringer comprises in general a pair of end castings II and I2 supporting an upper roll I3 and a coacting lower roll I4 which extend between the castings I I and I2 of the wringer. The upper roll I3 is journalled upon a fixed shaft I which also stabilizes the ends II and I2 of the wringer, and such ends are also secured by means of lugs I6 and I1, and the screws I8 and I9 to the trough base 2 which stabilizes and joins vthe lower portions of the castings I I and I 2.

The lower roll I4 is provided with a shaft 29 rotating in the bushings 2| and 22, respectively, which are carried in the

cradles

23 and 24.

Such cradles

23 and 24 are each carried upon the

springs

25 and 26, respectively, which springs are conned between the laterally extending

ears

21 and 28 of the cradles and the

spring seats

29 and 36 supported upon the tips of the fastening screws I8 and I9.

With this particular arrangement, the lower roll I4 is at all times urged against the upper roll I3 while permitting roll` I4 to move toward and away from the roll I3 during operation while articles of clothing are passing between the wringer rolls.

The manually operable means for operating the wringer comprises .a .crank 3l having a suitable handle 32 designed for hand or fingertip operation, such crank 3l terminating at the wringer end with a stub shaft 33 having a, tongue 34 which is pivotally connected by means of the pin 35 to the bifurcated end 36 of the drive shaft 28 that rotates the roll I4. Stub shaft 33 is held in operative driving alignment with the axis of shaft 28 by means of a locking sleeve 31 which is endwise shiftable to permit the folding of the crank about the pivot 35 and into a position alongside the wringer structure whenever the latter is moved into the tub I0 and into inoperative position as indicated in Fig. 5. Normally, the sleeve 31 is in the position indicated in the Figs. 1, 2 and 3 and such sleeve is of sufficient tightness to be frictionally maintained in its operative locking position wherein it prevents relative movement between the stub shaft 33 and the shaft 20 about the pivot 35 and in which position such sleeve disposes the crank 3| in operative wringing and roller driving relationship with respect to the wringer structure.

The wringer is pivotally supported adjacent the ends of the base portion thereof in the manner best illustrated in Fig. 2. The end casting II is provided with an extension 48 having a boss 4I disposed in direct alignment with a similar boss 42 formed on the end casting I2. A pair of

pivot studs

43 and 44 pass through aligned openings in the

walls

8 and 9 of the tub I8 and through suitable openings in the aligned bearing Washers 45 and 46 and are secured in threaded bores disposed in aligned relationship in the bosses 4I and 42 of the end castin'gs I I and I2 of the wringer structure.

The pivotal mountings described are disposed directly below the peripheral top bead 41 of the tub I0, and as shown in Figs. 2 and 3, the base trough of the wringer generally indicated at 2 terminates just short of the bead portions 41 of the

walls

8 and 9 of the tub I0 to substantially close orf this particular section of the upper end of the tub by means of the base trough of the wringer.

The wringer is normally held in the upright and operative position indicated in Figs. 1 to 4, inclusive, by means of a suitable latch which is best shown in Figs. 2, 3 and 4 and comprises a sliding bar supported for endwise movement through a suitable opening 5I formed in the projection 40 of the end casting .I I, such a bar having a tapered or wedge end 52 capable of locking engagement with the lower edge 53 of the depending flange 54 which forms an integral portion of the shelf 55 that is suitably secured to the walls of the wash machine tub Il) by the anges 56 and 51 through spot welding or by other fastening means. As shown in Fig. 4, the bead 1 of the wringer base2 is of a size and is so disposed and arranged to abut the upper surface portion 58 of the shelf 55 thereby locking the wringer I in fixed and upright operative position for use during the wringing operation in coaction with the sliding bar 50.

As further illustrated in Fig. 2, the lock bar 50 is provided with a depression 60 which coacts with a spring pressed ball 6I carried in a suitable bore 62 whenever the latch bar 58 is pulled by means of its handle 63 into the retracted position indicated in Fig. 5 holding such latch bar in this position by means of the ball 6I engaging Within the recess 60 in the latch bar. A second depression like 60 may be provided in the bar to hold the same in its locking engagement as shown in Figs. 3 and. 4 although it is better to depend upon the tapered surface of the end 52 for frictionally retaining the bar in its operative position and to rely on the wedge portion of this lock bar to tightly clamp the wringer structure by means of the bead 1 and the bar over the top and bottom edges of the ange 54 of the shelf 55.

A cover 64 in the form of a tray provides the nal closure means for the top of the wash machine tub I8 in addition to the wringer base 2 and the shelf 55 and this cover is disposed as shown in dotted lines in Fig. 4 during the washing operation. The shelf 55 is a means to place the wringer slightly inwardly from the adjacent tub wall. After the Washing operation lhas been completed, this cover 64 can be transferred to the opposite side of the wringer as shown in full lines in Fig. 4 to provide a clothes receiving tray for the articles of clothing that are passed from the tub I0 through the wringer I in the direction of the tray as described.

To accommodate the tray or cover 64 in clothes receiving position, as indicated in full lines in Fig. 4, the wringer end castings II and I2 are provided with projections 65 and 66 having recesses such as 61 to form hooks to accommodate the head 68 of the cover tray 64 While' a portion of the tray overhanging the washing tub I6 rests upon the top of the peripheral bead 41a of the tub I0 securely supporting the tray 64 in cantilever relation adjacent the wringer and in position projecting over the edge of the tub as clearly illustrated in Figs. 3 and 4.

After the wash day chores have been completed.

me wringer may be rotated into the 180 position indicated in Fig. by release of the latch bar 50- bringing the portion 3 of the base into horizontal alignment substantially adjacent the shelf 55 with bead B of the trough base engaging the edge 53 of the ange M of the described shelf 5I. The tray 64 may then be placed substantially as shown in full lines in Fig. 5 to close up the upper end of the tub so that the three units comprising shelf II, the base portion 3 of the wringer, and the cover 8l will completely close up the upper end of the wash machine tub I0. This rotation of the wringer into the inoperative and nested position within the tub i0 is also made possible by the construction of the crank 3| and the pivotal mechanism controlled by the slidable locking sleeve 31 together with the necessary clearance provided at the right hand end of the wringer as shown in Figs. 2 and 3 by means of the extension or projection 40 that permits the crank 3| to be rotated into the position indicated in dot and dash lines in Fig. 3. In this position the shaft 20 has been moved so that the pin 35 will be vertically disposed while the stub shaft 33 is then revolved 90 with respect to the operative axial position of the wringer shaft 20 bringing the crank 3| adjacent the side of the wringer rolls with the handle 32 obviously extending away from the rolls and into a position providing suiiicient clearance to rotate the wringer into the tub for storing purposes whenever the washing machine is not in use. Other possible relationships of the folding handle are also possible in providing the means explained for permitting the wringer to rotate from the Fig. 4 position into the Fig. 5

position or vice versa. v

Consideration of Fig. 4 will indicate that the cover is adapted to rest upon the upper end of the tub and a portion of said wringer to close off the remaining portion of the washing machine tub. When the wringer is in operation, the cover is adapted to rest upon the upper end of the tub under hook projections on the wringerr so. that the cover may be used as a tray to receive articles of clothing discharged from the wringer when the wringer is in operation. When the wringer is rotated within the tub as indicated by the arrow around the pivot 43, the bottom of the wringer is supported in horizontal position as the wringer is rotated in the horizontal position by abutment of the bead 8 against the projection 53 which limi its the rotation of the wringer in the horizontal position. From the above descriptions it will be appreciated that I have produced an inexpensive arrangement which adds considerable utility to the combination.

Changes in the exact form, design and construction-as well as in the combination of elements are contemplated, but such changes shall be controlled by the language of the appended claims defining this invention.
