of the top frame brings about de-clutching of the driving means to stop the wringer roll.

An additional object is to provide manually operated lever means disposed at one end of the 'wringer for operating the pressure elements to bring the wringer release into pressure relationship and retain the same thereat.

A further object is to provide roll mechanism comprising pressure retaining means disposed on either end of the releasable roll and connections between the mechanism of one end and that of the opposite end whereby manual operation of the mechanism at one end brings about identical operation of that at the opposite end.

Another object is to provide spring pressure mechanism operating on the upper roll, and means for adjusting the pressure associated with the lower roll.

A further object is to provide a manual water shed mechanism disposed below the lower roll and novel means for operatingthe same in accordance with the direction of rotation of the lower roll.

Other objects will appear in the following description and accompanying drawings in which:

Fig. 11 is a fragmental detailed view taken from line ll--H in Fig. 9 and Fig. 12 is a view similar to Fig. 11 showing parts in operated position as will be referred to.

Figs. 1 and 2 of the drawings showthe external portions of my wringer which may be briefly described as follows:

The numeral I 0 designates a lower frame member which includes conventional drain board portions ll disposed on either side and upright end members ill in .which upper and lower wringer rolls l2 and i3 are mounted.

A transverse top member 14 is removably attached to'the lower frame by means to be described and carries on either side a hand rail I5 the function of which will be later referred to.

The wringer frame is supported upon a head member l6 which is adapted to be mounted upon a post, support not shown.

The head member carries driving and control I mechanism for the wringer rolls, only a portion of which is considered a part of my invention.

That part of the mechanism not included in my invention will not be herein described further than to say that handles l1, l8. and i9 appearing in the drawings are connected with various elements of the mechanism to facilitate manual control of the wringer during practical use thereof.

Reference to Figs. 3 and 8 will disclose that the lower roll I3 is rotatably supported in the frame by means of bearing blocks 20 slidabiy supported in cage members 2| which are secured as at 22 to a lower portion of the frame. Fig. 8 most clearly illustrates that metal plates 23 are disposed below the bearing blocks whereby a bearing is formed for the ends of adjustment screws 24 which are threadedly mounted in a lower portion of the frame and are provided with lock nuts 25 whereby they may be locked in adjusted position. The screws are obviously effective to adjust the vertical position of the lower roll.

Upper roll I! is rotatably supported by meansof bearing blocks 25' secured in cage members 26 which latter are slidably. supported in depending end portions 21 and 21' of a longitudinally disposed bracket member 28. The bracket member is secured in transverse top frame member I 4 and the depending end portions are provided with slots 29 which slidably confine shoulder screws 30 projecting from the sides of cages 26. Thus the cages are mounted in the top frame I4 in a manner to be freely movable but not entirely separable therefrom.

A bar spring 3|, abutting the underside of top frame I4 at 32 has its ends resting upon cages 26 and is effective to urge the cages and upp r roll away from the top frame when the same is moved into elevated position, all as indicated in Fig. 5.

Pivotally attached at 33, to either side of bracket member 28 are depending link members 34 having pivotal connection at 35 with lever members 36 which latter are pivotally supported at 31 upon the end frames l2 and are connected to operate in unison by means of connecting links 38.

Figs. 3 and indicate that top frame I4 is movable relative to the lower frame into an elevated position shown in Fig. 5 wherein the link 34 and lever 36 are in toggle extended relationship or a lowered position shown in Fig. 3 wherein the link 34 and lever 36 are in toggle collapsed relationship.

It will be noted that with the parts in elevated position, Fig. 5, a lowering movement of the top frame will bring about rotation of links 34 on pivots 35 to place the mechanism in position shown in Fig. 6 wherein the upper wringer roll is placed in contact with the lower roll.

Figs. 6 and 7 also illustrate a lever member 46 pivotally supported on end frame l2 by means of a. pivot pin 4i secured in a bracket 42. The normal position of the lever is as shown lying adjacent the end frame I2.

The lever is fashioned to have a back wall 46' and side portions 40" and is thus adapted to conceal underlying mechanism when placed in closed position.

The lower end of the lever is left open so that the fingers of an operator may be inserted within its lower end to manipulate it to the angular position shown in dotted lines in Fig. 6.

A bifurcated link member 43 is pivotally connected at 44 with lever 40 and carries a pin 45 at its lower end. The pin extends from yeither side of the link and is slidably confined in slots 46 formed in bracket members 41 secured to the end frame.

Adjacent the pin 44, link 43 carries a pin 48 upon extending ends of which are attached link members 49 which latter have slots 50 at their opposite ends. The slots are fitted to slide upon studs 5! secured in the body portions of levers 36.

Figs. 9 and show in detail a lever or arm member 52 pivotally secured at 53 to one side of bracket member 28. A similar arm is likewise mounted upon the opposite side of the bracket.

A bifurcated arm 54 is pivotally mounted by a pin 55 in bracket 28. The outer ends of the arm carry a pin 56 the ends of which extend toward either side, through clearance holes in bracket 28 and slots 51 in arms 52, to a point in the operating path of levers 36 as shown in Fig. 9.

Since the ends of arm 54 operate as a unit, the pin 56 supports the ends of arms 52 in such a manner that the arms 52 move as a unit.

Figs. 9, 11 and 12 illustratein detail that hand rails l5, already referred to, are supported upon the top frame 14 by means of lever members 58 which are pivotally mounted at 59 upon thetop frame structure by means of enclosed brackets Coil springs 6| abutting the levers and brackets operate to retain the levers 58 in the horizontal relation shown in Fig. 11.

The levers are provided with inwardly extending finger portions 62 and those on the left hand end, Figs. 3 and 5, lie just below extending lip portions 52' of arms 52.

Fig. 12 indicates that downward movement of hand rails l5 brings about rocking movement of the levers as indicated in Fig. 12 whereby arms 62 are caused to move the pin 56 upwardly. A spring 63, hooked to pin 56 and pin 33 urges pin 56 and attached mechanism downwardly towardthe portion shown in Fig. 10. This movement will be referred to shortly.

Reference has formerly been made to the position of parts in Fig. 6 wherein the frame has been lowered to a point where the upper roll is resting upon the lower roll but with no pressure save that of the weight of the mechanism, and the parts are arranged in position for final manual actuation into pressure position.

It will be noted that the upper ends of levers 36 are fashioned to have a lip'or hook portions 61 which are adapted, when placed in position shown in Fig. 10, to engage the cross pin 56 and be confined thereby.

In order to place the parts in the described locked position the lever 40 is moved outwardly toward the dotted line position of Fig. 6 whereby the link 43 is moved upwardly and outwardly to engage the ends of slots 50 in links 49 with studs 5! and thereby urge levers 36 counterclockwise.

The described movement will obviously operate links 34 in a toggle manner to force the top frame downwardly to a closed position in which pin 33 abuts a recessed portion of levers 36 as shown best in Fig. 10.

During this lowering movement of the top frame the spring 3| is forced into abutment with bearing blocks 25 to bring the upper roll into pressure relation with the lower roll, the lips 61 are moved toward pin 56 and the pin is resiliently urged downward in such a manner that when lever 36 is rotated a suflicient distance the pin will drop ahead of the lips to lock the levers in closed position.

After the locking operation is completed, lever 40 may be returned to normal position, which movement is obviously permitted by slots 50,

The foregoing has described operation of the mechanism disposed in the left hand end of the wringer. It will be noted that the lever 36-link 34 mechanism just referred to is duplicated at the right hand end. Through connecting links 38, movements originating at the left hand end are duplicated at the right hand end whereby the top frame is made to operate in a uniform manner.

Release of the mechanism is obviously accomplished by manual downward movement of either of hand rails l5 to bring about upward movement of arms 52 and pin 56 as already noted, thus permitting lips 61 to escape the pin and levers 36 to rotate clockwise suificiently to permit rotation of links 34 on pivot 35 and consequent upward movement of the top frame to relieve the pressure exerted by spring 3!.

After release movements are completed the top frame and upper roll may be elevated a considerable distance as indicated in Fig. 5 to permit removal of large obstructions from between the rolls, however the position of the parts after releasement would normally be as indicated in Fig. 6 wherein they are disposed ready for final closure and lock as described.

The foregoing has described the pressure and release mechanism of my wringer.

ing mechanism co-operating with the top frame underlying mechanism.

- by means of a bracket 88 and urged upwardly by a spring 61 anchored in the head structure.-

Fig. best illustrates that arm 88 has an upstanding portion 88 resting upon an adjacent portion 88 of a lever member III which is also pivotally'supported on pin 85.

Arm 84 and lever 18 are independently movable on pin 88 but are normally induced to operate as a unit by reason of the portions 88 and 88 being held together by a spring H 1 Bpring ll is retained by an elongated rivet or pin 12 secured in portion 68 and passing through a clearance opening in portion 68. A washer on the end of member 12 confines the spring in such a manner as to abut portion 68 to hold it in contact with portion 68. It will be apparent that arm 64 may rock upon pin 85 without accompanying movement of lever 18 but the resultant compression of spring ll tends to urge lever 18 to rotate in unison with it. 1

It is to be assumed that lever 18 is bifurcated and its arms extend downwardly upon either sideof a clutch member 13.

The arms are angulated at their lower ends and each arm carries an inwardly directed roller 14 engaged in a groove 15 formed in the clutch member whereby rocking movement of lever 18 on pin 65 is effective to propel the clutch laterally as will be explained.

The clutch is slidably keyed upon a coupling member 18 which has an enlarged end portion H in which is formed a squared end portion of the shaft of lower wringer roll l3. The opening and shaft are so proportioned that the coupling member may be moved out of axial alignment with the shaft without destroying the driving connection therebetween.

The opposite end of the coupling member is rotatably supported within a clutch element 18 which has slots I8 formed in its outer end. In the slots are engaged rollers 88 mounted upon a pin 8| which is secured in the wall of a hollow hub portion 82 of a gear 82 not fully shown.

It is assumed that gear 83 is rotated by the driving elements of the wringer and has its bearing in the head structure at 84.

It will be apparent that the coupling member is freely rotatable within clutch element 18, that the coupling between the latter and gear 83 is such that it is axially moveable relative to the gear, that the clutch element is held in alignment by reason of its being sleeved upon couplingv member I6 and that the coupling member is supported at its opposite end by means of its connection with the wringer roll shaft.

With the foregoing in mind it will be obvious 'that with parts in position shown in Fig. 3,

wherein the top frame is placed in lowered position, arm 64 is rotated downwardly andlever I0 is moved into position to move clutch member 18- into engagement with element 18 to establish driving connection between gear 88 and the lower wringer roll.

It will further be clear that when the top frame is released and moves upwardiy,- spring 81- is elfective to rotate arm 88 upwardly as in Fig. 5, to bring about de-clutching movement of clutch member I! to break the driving connection.

The function of the coupling described in connection withspring II is to provide a means whereby the top member may be reset when the tooth and denture portions of the clutch are not in alignment. In such a case clutch member 13 is prevented from moving responsively to movement of .arm 84 in which event the arm may be reset, with spring II urging coupling movement of the clutch parts. Initial rotation of gear 83 will bring the clutch parts into alignment whereupon spring H will force clutch'member I3 into coupling position.

As a further feature of my wringer I provide a novel water shed mechanism which may be described as follows:

Figs. 1 and 2 show conventional drain boards H disposed upon either side of the wringer.

Figs. 3 and 4 illustrate that the members H extend outwardly and downwardly and terminate in 9. depending edge portion ll.

Below the drain boards II and the floor portion of the wringer frame are secured oppositely disposed trough members 88 extending from either side of the wringer frame to points below and inside of the drain board portions N.

Fig. 3 illustrates that members 88 are considerably narrower than the drain boards and are placed approximately central thereof.

A flipper board 81, having upright end portions 88, is pivotally mounted at 88 upon bracket members 88 secured to the floor portion of the wringer frame. It is so proportioned so as to overlie trough members as indicated in Fig. 4 and by means of its pivotal mounting is adapted to be tilted in either direction to shed water into either of troughs 85. An opening 88 is provided in the floor of the wringer frame whereby water falling from the rolls is conducted to a point above the flipper board.

The flipper is automatically actuated to shed water toward the side of the wringer receiving washed items by a mechanism comprising a grooved collar 8| secured upon the shaft of lower roll H.

A hairpin spring 82 is disposed in the groove and is slidably retained thereon in frictional relationship.

An extending portion 83 of the spring is loosely engaged between angulated forked portions 84 of an arm member 85 which passes through an opening 88 in the floor ofthe wringer frame and is secured to a shaft 81 the same being rotatably supported in brackets 80.

Upstanding edges surrounding the opening 86 prevent water accumulating on the wringer frame floor fro1n' flowing through the opening.

Below the flipper board and secured to shaft 81 is a double, arm member 88 and this is adapted to communicate movements of the shaft to the flipper board.

It will be apparent that rotation of the lower wringer roll in either direction will bring about similar movement of spring 88 to rotate arm 88 upon shaft 81 to tilt the flipper board in a Y frictional coupling afforded by spring 93, will tend to hold the board in position.

Initial opposite rotation of the roll will ob viously bring about tilting of the flipper board toward the opposite side.

Thus the water from the wringer is automatically drained toward the feeding side without attention from the operator and the water thus drained does not again come in contact with materials being wrung.
