MASSACHUSETTS WRINGER Application filed August 8, 1931. Serial 110. 555,612.

This invention relates to improvements in wringers, and is directed more particularly to improvements in wringers having safety features associated therewith.

The principal objects of the invention reside in the provision of a wringer wherein a pair of coacting rolls are releasbly held in operative engagement with certain parts readily accessible to the operator for manual manipulation whereby the operator may easily and quickly release the rolls from operative engagement.

Another object of the invention is the provision in a wringer of driving mechanism which is simultaneously disengageable as the rolls are released from operatlve engagement.

all to the end that the operator is safeguarded against injury.

Various novel features and advantages of the invention will be more fully hereinafter.

referred to in connection with the accompanying description of the preferred form of the invention taken in connection with the Y accompanying drawings which show a. novel combination and arrangement of parts.

In the drawings:

F ig. 1 is a plan-view of a wringer apparatus embodying the 'novel features of the invention.

Fig. 2 is a side elevational-view of the same.

Fig. 3 is an end elevational View of the right hand end of the wringer shown in Fig. 2.

Fig. 4 is an enlarged partial sectional and side elevational View of the wringer shown in Fig. 2. Fig. 5 is a sectional elevational view taken on the line 55 of Fig. 4, showing certain -modifications of the invention.

apparatus which may include a so-called head 2 and i a wringer indicated generally by 4. It is usual to provide the wringer head with driving mechanism while the wringer is supported and driven therefrom in some suitable manner.

The wringer head 2 shown consists of a shaft 14 and in this case the said shaft may carry a part16 rotatable in a suitable hearing 18 at the upper end of the tube 8. A

driving member in the form of a pinion 20,

is carrIed at the, upper end ofthe shaft 14 for driving the wringer apparatus.

A cam member 20 is oscillatable and reciprocable in the housing 6 and is hollowed out to receive driven gears 22 and 24 which are slidable and non-rotatable on a shaft 26. A non-round shaft such as shownis suitable, but the gears and shaft may have keys and ,slots associated therewith.

The'shaft 26, has one end 28 rotatable in a suitable bearing carried by a cap. 31 for the housing and its other end 29 is receivable in a tube or sleeve 30.

A pin 34 and angularly disposed slot 36v l 1' associated with the cam member 20 and the.

upper side of the housing are arranged so that the cam member is reciproc ted relative to the housing as it isoscillate. or rotated.

As it rec'iprocates in one direction or the other the gears 22 and 24 are moved thereby into and out of engagement with the drive pinion 20. Accordingly as one or the other of the gears 22 and 24 are brought into engagement with the pinion the shaft 26 will be driven in one direction or the other.

As shown in Fig. 4, the gear 22 is in mesh with the pinion 20 so that with the shaft 14 rotatable in acertain direction the shaft 26 will be rotated in a certain direction. These gears 22 and 24 are held in a spaced relation by means of a sleeve 25 therebetween as p of engagement with the pinion 20 the driv- .mg by means ofa flange member 50.

ing mechanism is in what may be called a neutral or inoperative position. i

The member 30 is rotatable in a barrel 40 which is oscillatable with the cam member 20 and housing 6 and is arranged as by pin 42 to be driven by the shaft 26.

The sleeve 30 is hollow as shown to receive an inner end 36 of a roll shaft 38. A nut 40 on the end of the shaft" may fit in a suitable bore of the sleeve or some other means may be employed whereby the shaft 38 will be I'utated by the sleeve 3 15 v The barrel 40 previously referred to and which is oscillatable relative to the housing is held against axial displacement in the hous- This flange member 50 may be a part of a frame F of the wringer, and is secured to the end of the housing 6 by means of suitable bolts or screws 52 or the like.

A pin 54 is carried by the cam member 20 and works in a suitable; bore in the member 40 so that as member 40 is oscillated the member 20 will be oscillated thereby while at the same time the member 20 may reciprocate in the housing quite independently of the member 40.

A fork or yoke member such as shown in Figs. 4 and 7 is secured by means of screws 62 to the ember 40. This fork 60 has an open ended 'slot 66 in the upper end which 1s directed upwardly for receiving a part asv sociated with. a driven roll as will later be described.

As the member 60 is swung in one direction or; the other the member 40 is oscillated to oscillate member 20. As the member '20 is oscillated it is reciprocated in the housing 6 means of the pin and slot arrangement described so'as to move the gears 22 between a neutral position and a position where either one or the other of the gears meshes with the drive gear 20.

Aldetent 41 in a bore 43 of the housing at thelower side thereof is urged by a spring 45 so as to engage a socket 47 of the member 20. The bore and socket are arranged so that the detent functions to yieldably hold the member 20 in a neutral position when the gears 22 and 24 are out of engagement with 1 gear 20.

The wringer frame F may take any form desired, but in the form of the invention shown in Fig. 2 it has upwardly extending end portions 70 which may be hollowed out as in Fig. 7. Bolts 72 are siidable therein and have springs 74 disposed between heads or nuts 76 and shoulders 78. These springs urge the bolts downwardly and the upper ends of the bolts are pivoted at 80 to cross bars or saddles 82, as shown in Fig. 7.

A driving roll is carried by the shaft 38 which extends between the end portions 7 0 of the wringer frame and is suitably journalled in the outermost portion 70.

A driven roll 92 which is entirely separable the lower drive roll. By releasing the roll 92 from the members 82 the operator of the wringer is safeguarded and the means for releasably holding the roll 92 in the saddles and in operative engagement with the drive roll will nowdoe described.

- The members 82 are provided with vertical y disposed slots on their adjacent inner sides for receiving the ends of the roll 92. As shown in Fig. 7, the side walls of the slots 100 are provided with circular'or curv ing seats 102. The roll 92 has a shaft 103 which carries inner races 104 of ball bearings, hubs or the like. An operating bar structure 110 extending from end to end of the roll 92 has end portions or arms 112 which are journalled on the parts 104 described whereby the roll and shaft are rotatable relative to 110 lower the roll 92 into place.- The ends Q 7 of the roll may be dropped downwardly into the slots 100 of the saddle members and when the roll 92 contacts with the roll 90 the mem- 120 on the saddles adjacent the seats are arranged to coact with cams or studs 122 on the member 110. The cams and cam faces are arranged so that as the member 110 is swung downwardly the roll is moved sideways of the slots 100. In moving sideways the part 112 of the member 110 enters a seat 102 and bymeans of the cam arrangement described the roll 92 is releasably bed in the seat and in operative engagement with the drive roll 90.

' WVith the roll 92 removed from the wringer the yoke 60 is disposed in a neutral position centrally of the slot 100. In this posltion the gears 22 and 24 are out of operative engagement with pinion 20.

As the roll 92 is lowered into the slots 100, as described, a part 111 associated therewith or with its shaftis received by the yoke. As the roll is moved sideways of the slot 100, as

$5 ber 110 is swung downwardly. Cam faces i described, the yoke is swung thereby so as to oscillate member 40 and cam 20 which is simultaneously reciprocated to bring gear 22 or 24 into mesh with pinion 20 whereby the lower roll is driven for driving the upper roll.

The parts are shown in Fig. 7 in operative relation and the shaft 14 may be driven in such a direction that the rolls 90 and 92 will be driven in the direction of the arrows shown in said Fig. 7, and in which case the operator will ordinarily stand at the left of the parts as shown. In this position should it be necessary to release the roll 92 from operative engagement the operator may by con- 112 which will strike upon or against the-in-- ner side of the slot 100 the roll moves inwardly of the slot so as to be free to move upwardly. In this way objects between the rolls are relieved of pressure.

It is noted that since the saddles are yieldingly held against upward movement that the roll 92 is yieldingly held in operativeposition against the roll 90 therebelow., In this way the rolls are capable ofv receiving therebetween various thicknesses of material for a proper wringing action. I

A drain board 130 as shown in Figs. 4 and 7 is dis osed between the ends of the frame 70 and is pivoted as at 132 for tilting movements. A lug 134 extending upwardly at one end thereof is disposed in the path of a mem ber 136 associated with the shaft 38. These parts are so arranged that in the rotation of the shaft 38 the member 136 will abutthe member 134 to tilt the member 130 as shown in Fig. 7. Should the shaft and roll rotate in opposite directions theparts are so arranged that the drain board will be tilted in an opposite direction.

Inlieu of the pm connections shown in Fig. 7, the bolts 72 and saddles 70 it may be desirable to provide an enlarged part 140,

on the upper end of the bolt which will seat in a suitable socket provided in the saddle A bolt 170 is slidable at upper and lower ends in the housing 6 and a lug 171 as shown in Fig. 4. Its lower. end is arranged to lock in an opening of an arm 172 of the tube 12. When so locked the housing and wringer are held against relative rotation. I

An opening 173 is provided in the lower side of the cam 20 to receive the upper end 174 of the bolt. This opening is? disposed in such a way that it is above the rod only when the cam 20 is in an inoperative neutral position and in that position only may the bolt 107 be raised to allow the head to turn relative to the tube 12.

In an operative position of the parts shownthe head is locked against rotation. When the cam is in a neutral position the bolt may be elevated to allow the head to rotate.

A spring 175 between the housing and a hand grip 176on the rod urges the bolt downwardly so that a'pin 177 abuts the arni 171.

By the means of the bolt itfis impossible to movethe head while the wringer is in stud and cam are thus disengage 92 is free to move inwardly. There is a tendv ency by reason of the normal pressure between the rolls for the upper roll to move" inwardly and upwardly whenever the cam operation which is desirable for safety reasons.

tus it will be assumed that the upper roll 92 has been separated from the wringer. With this roll separated from the wringer the yoke 60 is in a neutral position so that its open In describing the operation of the apparaupper side is centrally of the slots 100 of the saddle members 82. In this neutral position the cam member 20 is located so thatneither of the gears 22 and 24 is in mesh with the gear 20.

To operate the wringer the operator grasps the member 110 and by it lowers the roll 92 so that its ends are receivable in the slots 100 of the saddles. The roll 92 is lowered until it rests on the lower .roll and the member 110 is swung in one direction or the other so that the stud 122 engages with one of the cams 120. As the member 110 is swung downwardly as before stated, the cam arrangement causes the roll tobe moved trans versely of the slot so that the part 112 enters a seat 102. By means of the stud and cam and the seat the roll is releasably held in operative relation on the drive roll 90. '.As the and stud are disengaged.

In the event an operator has a hand caught between the rolls and then in some manner contacts with and moves the lever 110 up or down the upper roll will by reason of the pressure exerted thereagainst move upwardly to instantly release the part caught'between the rolls.

It will be noticed the rolls are held in operativeengagement by manually releasable means and that the driving connections for the wringer are moved into and out of dl'lV- ing engagement accordingly as the wringer rolls are brought into and out of operative engagement.

According to the form of the invention shown in Fig. 5, the roll 92 is released by an upward movement only of the member 110.'

In such a case a cam face 160 extends downwardly from the upper end of the saddle against the bottom of which the stud 122 abuts when the member 110 is in operative position.

Having described the invention in'the form at present preferred what we now desire to therein,
