The wringer frame consists of :a head-i2 and an end frame I which are apart `and connected by. longitudinal l members t, ail of The .19H-

A shifter Il, shown more clearly in Hg. 2,

has a bearingpartl! which isrjournalled on the hub!! ofthe head for oscillatory move- 45 ,.ment's." This shifter has an opening in lits rear sidewhich receives a pin I6 xed to and extending from nie oscillator u. iin vupper foi-k part'fll onthe'shitter has a slot Il' and more or lesssdlverging arms 82. At the lowerside of theshifter-member 5l there is a pin II for op veraizing a drain board as will later appear.

c A lower rou wim o short pero n' Aon ite inner end which carriesapin u. Thepartn' isrecivableinthesocketofthedrlvingshaft 20 and the pin 64 is received in a. suitable transverse slot provided in the wall of the socket 38 whereby as the shaft 20 rotates the roll 60 is rotated thereby. The other end 66 of the wringer roll shaft 62' is journalled in a bearing 68 which is suitably seated in the end frame 4.

Receivers such as are provided in 'association with the head 2 and with end frame 4 which are substantially 'alike and similarly mounted. 10 The receivers 10 are slidable up and down in the head 2 and in the end frame 4 and have ears or lugs- 12 on their lower outer sidesto which are secured rods or bolts 14 having `heads 16 at their lower ends. 15 'I'hese rods 14 are slidable in lugs 18 associated with the head 2 and the end frames 4 and springs 80 around the rods and between the lugs 18 and and heads 16 of the bolts are under more or less tension to urge the receivers downwardly. 20 When the receivers and parts associated therewith are moved upwardly relative to the main frame, the springs are compressed so that the receivers are under tension to tension an upper roll which, with ya separate frame member, is releasably locked to the receivers as will later appear. A

The receivers 10 are hollowed out at 8| on adjacent inner faces and have inwardly extending side ilanges such as 82 and a lower flange 84 (see Fig. 5). Grooves 86 extend inwardly from the sides of the receiver on the adjacent inner faces thereof and are connected to a vertically extending groove 88 in the upper part of the receiver which is in alignment with a groove 90 in the lower part thereof. Enlarged recesses 92 are associated with the grooves 6K6 and 88, as shown.

Lock members |48 shown in Figs.` 3 and4 are associated with each receiver. These'have studs |82 adjacent their upper sides which are journalled in the receivers 18 so they may oscillate betweenthe neutral inoperative and operative positions shown in Figs. 5 and 6. A pin such as |04 projects rearwardly from the lock member 100 which is ted with the head 2. -This pin |04 is disposed in the slot 6l of the shifter member il, which, as stated, is oscillatable in Grooves |86. are provided on the inner faces of the lock |88 which, when the locks are in the position shown in Fig. 5I align with the grooves and 8l of the receivers. The locks |00 are shown in a neutral position in Fig. 5 and in an operative position in Fig. 6. As they Din |84 working in the slot 68 of the shifter 50 osoillates the shifterin one direction or the other. The shifter in turn oscillates member 24 so as t'o'move the gears I6 and' I8 into and out of cent with pinion |4.

Springs III are associated with each receiver and extend through slots'1l2 in the upper sides of the locks |08.' The`s1ots ||2 are arranged so that the bottom sides thereof bring up against the members I0 and being spring-like the springs III tend to urge the locks to their neutral position shown in.?lg.'5.

A separate upper roll frame |20 has a longitudinal extending manually engageable part l|22 on the ends of which are depending portions |24 and an upper roll |26 is journalled in the said parts |24 of the frame. Lower projections |28 extend-outwardly fromv the end parts |24 of the frame |28 as do upper projections |80. u 'nwe rejections cO-orerte with the receivers oscillate or swing between these positions the and locks to facilitate the frame being releasably locked under tension and released from the wringer.

The frame |20 may be called a guard and having the roll associated therewith it may be removed from the wringer or releasably locked in operative position therein.

In describing the operation of the wringer it will be assumed that the upper roll frame |20 has been removed from the wringer and that the parts are in the relative position shown in Fig. 5.

To operate the wringer the operator grasps upper roll frame |20 and swings it so that projections |28 and 130 are inserted in slots 86 of the receivers. Then it is swung to an upright position, the projections |28 and |30 passing downwardly relative to slots 88, |06 and 90. The

roll |26 comes to rest on the lower roll 60' with the projections |28 of the frame in slots 90 of the receivers and projections |30 of the frame are in slots |06 of the locks |00. This is the neutral position of the upper roll frame The frame 120 may now be swung to an operative position such as shown in Fig. 8 and releasably locked in said position simultaneously engaging the driving mechanism. To do this' the operator may grasp the frame |20 and swing it and it may be swung in either direction and cause the frame |20 and its upper roll to be releasably locked in operative position and cause the lower roll to be driven. As the frame is swung the locks |00 are swung thereby and the lock |00 at the head end of the wringer having pin |04 in forked upper end of member 50 oscillates said member which in turn oscillates gear shifting member 24.

As the locks are swung by swinging of frame |-20 the lower ends |40 of the locks ride on or pass on the lower projections |28 of frame |20 which locks hold the frame in the wringer. Then when an object is passed between the rolls the springs associated with the receivers resist the separation of the rolls.

The lower edges |40 of the locks |00 are preferably eccentrically disposed relative to their axis of oscillation. With the upper roll bearing on the lower roll and as frame |20 is swung to an operating position, the eccentricity functions to gradually elevate the receivers against the springs and therefore gradually subject the upper roll to the tension of the springs. This is desirable as a'minimuin of eifort only is required to set the parts in operativecrelation.

- With the frame |28 and its roll releasably locked in operative position, material may be passed between the rolls. The upper roll resists upward movements due to the springs 80 to bring about the wringing action. In case it is desired to release the upper roll, the frame |20 need only be moved from such an angular operative position as is'shown in Fig. 8 to its neutral position centrally above the rolls. This is easily accomplished by the operator who merely swings the frame |20. As the'frame |28 is swung from an operative position'such as shown in Fig. 8 to an inoperative, neutral position, the upper projections |88 of the frame in 'slots |86 of locks |00 swings said locks to their neutral position 'which releases Ythe frame |20 and moves thel shifter l0 to its neutral position throwing the y gears out-of engagement.

- When the parts are in this neutral inoperative position, the frame |20 may be' moved upwardly because the projections |28 and |88 of the frame amers when released. To prevent the frame from being thrown from the wringen/the upper projections l |30 of the frame abut the upper side of the recesses 92 of the receivers and above the slots $8 thereof. In any event, however, when the frame is released the rolls are separable sumciently to permit the withdrawal of anything ltherebetween. When it is desired' to remove the frame from the wringer it is moved upwardly and then tipped to the dot-dash position shown in Fig. 6 so that it maybe drawn sideways from the receivers.

A drainboard I Il is pivoted at |52 to the head 2 and end frame 'l for' tilting movements and it has an upstanding part l" on its one end adjacent the head which is recessed at; .-IIO to recelve the pin Il oi' the shifter 50. As the shifter oscillates the pin therefor acting in the recess I" causes the drain board to be tilted.

Where -it is desired to provide a wringer whereinthe locking of the frame in the wringer does not necessarily engage the driving mechanism there may be an operating handle Ill iixed to oscillatable shifting part 24 which extends through an angularly disposed slot |38 ,of head 2. As the handle is oscillated the part `24 is reciprocated to engage the gears.

With this arrangement the frame may be tilted with one hand and handle |36 may be oscillated with the other. These may be operated simultaneously or at different times as may be desired.

While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes and modincations may be made therein without departing from the spirit andiscope of the invention.
