This invention `relates to improvements in clothes wringers of the type commonly employed on domestic washing machines. It has particular reference to wringers having a pair of squeezing rolls arranged to be driven by power supplied from the motor which drives the moving parts of a washing machine.

It has been a primary object of the invention to provide a wringer of the character specified that is simple of construction, efiicient. safe and reliable in its operation and capable of use with a minimum of en'ort on the part of the operator. In its preferred form the improved wringer comprises a main frame carrying yielding, spring 10 urged bearings for the lower roller and a separable cover member carrying the bearings for the upper roller. A lever is provided which with one movement will serve to shift the upper roller to a xed position against the lower roller and establish a yielding pressure between them. At the same time latching means associated with the cover are operated to retain the latter in xed relation to the main frame. Preferably also, provision is made for connecting one oi the rolls with the driving mechanism as the pressure is established between them. When it ls desired to release the tension on the rollers the same lever may be operated by either a steady pressure or a quick blow depressing the end through a small angie. A blow of suilicient force may be quickly and readily struck with either hand which is desirable in the event one hand has become caught in clothes entering the wringer or has been drawn between the rolls. Operation of the lever in this way serves to instantly release the cover from the frame, relieve the pressure between the rolls. and disconnect the rolls from the driving mechanism.

By providing bearings for the upper roll in a cover separable from the main frame and controlling the latching of the cover by the roller tensioning means an arrangement is produced which enables separation of the rolls a considerable distance when not tensioned without requiring a frame of any great height. This materially enhances the appearance of the device and presents other advantages.

Other features and objects o! the invention will appear from the detailed description of an illustrative form of the same which will now be given in conjunction with the accompanying drawings in which:

, Referring now to the drawings, the illustrative 35,

wringer is provided with a main frame Ill of suitable fo'rm and construction to support the various operative elements of the structure. As best shown in Fig. 3, this frame may be formed with laterally extending portions arranged to provide 40 supporting and guiding surfaces for the clothes as they are fed into the wringer. Securely attached to the main frame is a frame Il, of what may be designated the wringer head, which houses the driving connections for the rolls of the 4,5 wringer and provides for the attachment of the wringer to a washing machine. The connection between the trames Il and Il may be effected in any suitable and convenient way. As shown, a pair oi' strap members l2 may be secured to one 50 end oi frame i0 by means of bolts i8. The upper ends oi' these straps are bent over and downwardly. as indicated at Il. to receive a projection l5 integral with the wringer head frame. This iirmly anchors the two frames above the 55 horizontal center line. The lower ends of the strap members are bent outwardly as indicated at il and are connected with the bottom of the frame Il by means of screws l1.

Over the top of the main frame I l is provided a cover member il having a belled portion Il around three sides of its lower edge ntting over the upper end of the frame Il. The fourth wall of the cover member. lying adjacent the wringer head, is straight. as indicated at 2li. and rests' upon the upper edge of the corresponding wall 2| of the frame ill. Within the cover Il there is provided at each end an auxiliary frame l! adapted to support various elements to be hereinafter described. These auxiliary frames may be secured to the cover in any convenient way. As shown, each may be provided with an elongated slot in a vertically extending portion arranged to snugly nt over a projection 23 integral with the adjacent end wall of the cover. The attachment may then be completed by securing outwardly extending feet Il of the frame, by means of screws or the like, to bosses 2l integral with the top of the cover member. Vertical, downwardly extending portions !I of the auxiliary frames lie closely adjacent to the end walls of the main frame and thus serve to maintain proper alinement between the cover and the main frame as the cover is lifted and lowered. As will later appear more clearly, the auxiliary frames provide a convenient subassembly of parts associated with the upper roller.

At each end of the main frame suitable guideways 21 (Fig. 3) are provided forretalning and guiding the vertical movements of bearing supports 28. The lower ends of the latter rest upon the ends of a spring bar 28, which extends longitudinally of the frame beneath the rollers. The vertical position of the spring bar may be made adjustable, in a manner well known in the art, the adjustment being effected by the turning of a rod il. It will be understood that the vertical adjustment of the spring bar serves to vary the pressure between the rollers when tension is established in the manner to be explained. In the upper end of each of the bearing supports 28 there is mounted a bearing block Il. preferably formed or oil-saturated wood providing continuouslubrication for a shaft 32 extending from the opposite ends of the lower roller I3 and arranged to be supported by the blocks Il.

At the end of the shaft I! adjacent the wringer head there is provided a collar 34 which is secured to the shaft by means of a pin I5. I'he collar ll extends beyond the end of the shaft and provides a socket to freely receive the end of a splined connector l which is connected with the collar Il through any suitable form of imiversal joint. For this purpose a pin 3l extending through the connector It has its projecting ends provided with flat sides capable of slidingly cooperating with slots 38 in the collar 34. As shown, the axis of the connector Il is at an angle to that of the shaft 32, the degree of this angle varying with the podtion of the lower roller as the wringer is operated. It will be lmderstood that in the rotation of the shaft 82 and connector Il the latter will be free to rock in all directions relative to the shaft due to its ability to pivot about the pin l1 and due to the movement of the ends of the pin I1 in the slots 8i. The opposite end of the connector 3B is freely supported by a member I! carried by a sleeve Il journaled in a bearing provided in the frame l I. A universal connection is provided between the member 8l and sleeve ll so that rotation may be transmitted from the latter to the member even though these parts are not axially alined. Forthispurposethereisshownapinll carried by the sleeve Il and having flattened portions arranged to slide freely in slots I! provided in the wail of the member I. At the end of the sleeve III there ls secured or integrally formed a bevelled gear Il arranged to be driven in either direction through connections not shown but well known in the art. It will be understood that the power for driving the rolls of the wringer is normally derived from a shaft extending vertically along the side of a washing machine and is transmitted through the gear ll and the remaining connections explained. However, the connection with the rolls is controlled by a clutch whose operation will be more fully explained hereinafter. For the present it may simply be explained that the connector I0 is not arranged to be directly driven by the member 39 but may be coupled with the latter through a slidable collar member 44 having one or more projections 4l arranged to be engaged with corresponding notches It in the member 39. The collar Il is splined to the connector and is arranged to be shifted by devices later to be explained to e'ect the coupling action mentioned.

Cooperating with the roller 3l is an upper roller Il which, like the lower roller, may be formed of any of the usual materials, such as rubber. This roller is carried by a shaft 4B which extends beyond the ends of the roller and cooperates with bearing blocks 49, preferably formed of oilsaturated wood. These bearing blocks which receive the upward, pressure of the shaft are retained by U-shaped, yoke members 50. It will be understood that the construction at the two ends of the roller is the same and therefore only that at one end is shown in detail. To retain the roller in the bearing assembly, when it is lifted away from the lower roller. a strap 5|, secured in any suitable way, as by the screws shown, to outwardly extending portions 52 of the yoke 50. is passed beneath the end of the shaft.

Each yoke 50 is pivotally mounted, by means of pins 53, in downwardly extending arms il of a member 55. The latter is in turn pivotally connected by pins 58 with arms l1 of a yoke member 58 pivotally supported by the auxiliary frame 22 by means of pins 59. It will be seen from the foregoing that the movable bearings for the ends of the roller shaft I8 are carried by the auxiliary frame 22 and may therefore be attached to and detached from the cover as a unitary assembly. The member 55 is provided with an arm Bil extending away from the opposite side of the pivot 56 from the arms 54. As shown in Figure 4, each member 55 may be provided with two arms B0 so as to permit use of the member at either end of the cover. A pin BI mounted in the utilized arm Sii carries one end of a link 82 whose opposite end is attached to a pin I3 inserted in a boss Il extending from a disc 6l. It will beunderstood that two links 62 are connected with the member il. extending from the bearings supported at the t'wo ends of the shaft I8. Disc BI is rotatably mounted in a small housing il rigidly secured in any suitable way to the front of the cover Il.

Adjacent the disc 65 there is mounted within the housing B6 a ring 61 which is held against rotation within the housing by the inter-engagement of projections 6B on ring B1 with projections I9 extending inwardly from the walls of the housing. At the center of the disc B5 there is provided an integral. axially extending sleeve ll having a lug or projection 1i forming a radial face of the disc BB.

:,ivavis extension thereof over a suitable arc of about This projection, as will be explained more fully hereinafter, is arranged to cooperate with a pro- .lection l2 extending radially inward `irom the ring il. A lever'lt having ahandle portion normally extending substantially horizontally in of the cover is provided with Va reduced portion Il around the pivotal axis having a bearing in the outer end of the housing It. From the edge of the reduced portion 'M there is provided an inward projection, a part 1I of which, covering an arc of about 90, extends only into the plane of the projection 1i of disc and not into the plane of the ring Il. The remaining part 1i of the handle projection, covering an arc of about 60, extends through the opening at the center of the ring 01 substantially to the inner surface of the disc 68. A stud 'I1 anchored within the handle 13 in any suitable way. as by having the metal of the handle cast around the stud and into a grooveadjacent the end or the latter, extends through the opening in the sleeve 1I and projects a slight distance beyond the opposite A groove adiacent the outer end of the stud 11 is arranged to receive a spring ringy or washer which, upon the projection of the stud beyond the surface of the disc IB, expands into recesses provided in the pins 63. The bosses M, it will be understood, are undercut to permit this cooperation of the lock ring with the pins. This provides a simple and convenient method of simultaneously locking the handle and pivot pins in assembled relation.

A spring 19,' having one end engaged in a notch BB cut into the reduced portion 'Il of the handle and having its other end inserted in an opening Il in the projection 12 of ring l1 serves to constantly urge the handle in a counter-clockwise direction, as viewed from the front of the wringer. A spring 82 attached at one end to the pin 6I and at its other end to a boss B3 extending downwardly from the top of the cover member Il tends to constantly urge the link 62 in the direction oi' the disc Bl. Referring to Fig. 2, it will be seen that the arm l1 of member 58 and the arm 5I of member U6 constitutes a toggle. Movement of the link 82 toward the right (Fig. 2) in the manner to be explained serves to straighten the toggle and thereby force the yoke B0 with the bearing block 49 downwardly. Movement of the link B2 toward the left, on the other hand,

serves to break the toggle and lift the bearing into the position indicated in Fig. 2. The spring 82 always tends to break the toggle in this manner. When the links B2 are in the position shown in Figure 12, which corresponds with the posi tion of the parts indicated in Fig. 2, the movement of the links under the iniiuence of the spring 82 is limited by the engagement of the surfaces Il of the pair of links. When the links are in the posi-tion indicated in Fig. 1, their ends connected with the pins 63 are slightly beyond the dead-center position and the springs 82 tend to continue the clockwise rotation of the disc 65. Movement of the parts in this direction beyond the position indicated in Figure l, however, is prevented by the engagement of certain shoulders, as will now be explained.

Referring to Figs. 8, 9, and 10, when the rollers are separated and the links B2 are in the position indicated in Fig. 12, a shoulder Bl formed by the projection i8 of the handle is normally held in engagement with a surface B6 on the projection 'I2 oi the fixed ring. The spring 18 serves to hold the handle in this position while, as pre viously explained., the springs I2 serve to hold the roller shifting mechanism, including the links 62, in the position determined by the engagement of surfaces I4 of the links. At this time a slight clearance is provided between a surface l1 on the projection IB of the handle and a surface ll on the projection vilroi disc ll. Now. when it lis desired to shift the upper roller into engagement with the lower roller, the end of the handle Il is lifted and the handle is rotated in a clockwise direction, as viewed from the iront of the wringer, through an angle of about degrees. After a very slight idle movement, the surface 81 is brought into engagement with surface lil and hence the projection 1I and disc B5 will be rotated with the handle through most of. the arc of movement of the handle. ThisV rotation of the disc Il will be resisted by the springs 82 until the pins 63 are carried to the dead-center position, beyond which the springs will assist in the further movement of the disc. The movement o! the parts will be arrested when they have reached the position indicated in Fig. 1 by the engagement of a shoulder 89 on projection 1I with a shoulder lion the iixed projection 12. The handle 'i2 may now be returned to substantially but not quite its initial position or if released it will automatically return under the influence of the spring 1l. The links 62 and the associated parts, however, will remain in their newly set positions due to the tendency of the springs l2 to continue the rotation of the disc 65 and hence to hold the shoulders l! and 90 in engagement. In the shifting of the parts in the manner explained, the upper roller will be forced against the lower roller and will depress the latter slightly against the action of the spring bar 2l. Accordingly, the rollers will be pressed together under a yielding force, the magnitude of which may be determined by proper adjustment of the bar 2l. As clothes are fed through the wringer, when in this condition, the lower roller will be depressed slightly further and will be restored in the usual manner by the spring bar as the clothes pass out from between the rollers. e

Now when it is desired to release the tension between the rollers at the end of a desired ironing operation, or in an emergencyl as when the hand of the operator becomes entangled in the clothes entering the wringer, it is simply necessary to depress the free end oi' the handle il through a slight distance by either a steady pressure or a sudden blow. It should be observed in this connection that when the handle is restored by the spring 19, following the tensioning of the' rollers. it does not return to its initial position but is arrested about 30 to 45 degrees prior to reaching its initial position by the engagement of a shoulder li formed at the end of the projection 'i5 with a portion of the surface 89 of the projection 1I. A suitable clearance remains between the shoulders -85 and 88 at this time. Accordingly it will be seen that when the handle is depressed in the manner explained, through an angle of 30 to 45 degrees, the disc B5 is rocked through the same angle as the handle and this is suiiicient to carry the pins 63 beyond the dead center position. As soon as the pins pass dead center, the springs 82 become eiective to quickly restore the parts to the position indicated in Fig. 2. thus elevating the upper roller and releasing the tension between the'rolls. Surface il! on the handle projection is now engaged with the surface I8 on the iixed projection and the parts are 'to be lifted from the frame.

again in position for a repetition of the tensioning operation.

In the foregoing. the fact that the cover il ls normally separable from the frame III has been ignored. Obviousv it would be impossible to establish pressure between the rollers by the mechanism explained so long as the cover is free Provision is accordingly made for attaching the cover to the frame whenever pressure is to be applied between the rollers. For this purpose a series oi four latch dogs l! is provided. one adjacent each corner of the cover member, these dogs being pivotally carried by pins ll extending from portions of the auxiliary frames 22. In line with the hooked ends of the latch dogs the frame il is provided with inwardly extending projections I4 presenting shoulders with which the dogs may become engaged. Each dog has a tail portion l5 which extends over the laterally projecting portions l2 of the yoke 50. This arrangement is such that when the yoke Il is elevated, the tails $5 will be engaged to rock the dogs 'into the position indicated in Fig. 2, out of engagement with the projections Il. However, when the yokes 5B are lowered to carry the upper roller against the lower roller, the dogs are permitted to swing by gravity into engagement with the projections ll. If the force of gravity is insuflicient to carry the dogs into latching position, the action may be made positive by the engagement of the projections 52 with camming surfaces 96 on the dogs. The cooperation of these parts. furthermore, serves to hold the dogs positively in latohed position so long as the upper roller is in its tensioning position.

As previously indicated, means are provided for coupling and uncoupling the lower roller with relation to the driving mechanism by means of the clutch element Il. The mechanism for shifting this clutch element comprises a yoke 91 carrying at each of its free ends a block 9| arranged to cooperate with a groove extending around the element M. The blocks l are pivotally mounted on the yoke arms to permit them to tilt into the proper positions. The yoke 91 is carried by a rod 9! mounted in portions of the wringer head frame ii. Also mounted upon the rod 98 is a rockabie frame IM having a cross member ill adapted to engage the cross member oi the yoke 91. The forward end of each arm of the rockable frame is formed into a rounded projection |02 each engaging the under sideof a laterally extending foot IDI formed on the yoke 5U. As this yoke is depressed, in the manner previously explained, it will rock the frame in a counter-clockwise direction (Fig. 2). The arms of the frame lull are cut out, as indicated at lill, to receive the feet |03 of the yoke M as the latter is moved downwardly. A spring illl looped around the pin I9 and having one end engaged with the back edge of the cross member of yoke 91 and its other end hooked under an arm of the frame |00 serves to normally hold the yoke and frame in the position indicated. A second spring i", coiled about the pin 89 and having one end hooked under a portion of the frame i I and its end |08 hooked under an arm of the frame |00, serves to rock the latter as well as the yoke I1 in a clockwise direction (Fig. 2) to maintain the projections |02 in engagement with the feet lill. Should the bearing yoke SI be moved downwardly at a time when the projections I of the clutch element 4l are not alined with the notches Il, the frame i" may be depressed and exert a yielding pressure upon the yoke I'I so that the latter will be shifted by the spring ICI as soon as the clutch elements are brought into proper registration.

In order to prevent complete disengagement oi the cover il from the main frame. links iid are preferably provided, one at each of the corners of the cover. Each links is pivotally connected with a downwardly extending portion of the auxiliary frame 2l and each is provided with an elongated slot ill arranged to cooperate with a stud H2 extending from the main frame il. Thus. while the cover is normally separable from the main frame, the extent of separation is limited by these links.

The mode of operation oi' the various portions of the improved mechanism has been explained in considerable detail as the description has progressed. Accordingly a general summary of operation is believed to be unnecessary. Sumce it to say that when the rollers are separated, as indicated in Fig. 2. the latch dogs II are disengaged from the projections $4 on the main frame so that the cover may be lifted to the extent permitted by the links lil. At the same time the rollers will be disconnected from the driving mechanism by the disengagement of the clutch elements II and M. When it is desired to render the wringer eifective, the handle 'I3 is grasped and rocked in a clockwise direction. as viewed from the front of the wrlnger, through an angle of about 150 degrees. This serves to straighten the toggle mechanism at the two ends of the upper roller, thereby lowering this roller into engagement with the lower roller and forcing the latter downwardly slightly to place the rollers under the yielding pressure of the spring bar I9. At the same time the downward movement of the bearings for the upper roller causes the dogs 92 to be engaged with the projections 94 on the frame and thus prevent the lifting of the cover so long as the rollers are under tension. Moreover. the downward movement of the right hand bearing for the upper roller causes the sliding of the clutch element Il through the action of the frame Illl and yoke 91 to connect the lower roll with the driving source. I'he upper roller is simply driven by frictional engagement with the lower roll. Handle 'Il is restored to a position in which its shoulder 'l engages the shoulder Il of disc Il. When the wrins'er is to be rendered inen'ective the handle is simply depressed or rocked counter-clockwise through an angle of 30 to 45 degrees. this being sufilcient to carry the disc l5 past dead center so that springs 02 may restore the parts to their original positions. The latch dogs 82 are withdrawn by this operation to permit lifting of the cover and the clutch n. u is disengaged.

While an illustrative iorm of the invention has been described in considerable detail, it will be understood that various changes may be made in the construction and arrangement of the various portions of the device without departing from the general principles and scope of the invention. Certain parts of the construction disclosed may be omitted altogether or replaced by modified devices. The invention is not to be considered as limited other than in accordance with the terms of the appended claims.
