1 isa plan view ofa 'wringer embodyemvention;

F ig, 3 is a fragmentarycross-sectional view taken on line 3 3 in "Fig. 2. n

, Referring in deta'ilto the drawing,,10 indicates a wringer machine ,consistin of upright standards 11, 11 secured to a hase 12,

v and a tress-member13norinally secured "in "position between the upper bifurcated ends 11" of said standards, asshown in Figs. 1 and 2.; Thestandzirdslhll? carry thegear casings 14, which are housed suitable gearings comprising pairs of gears indicated in dottedlinesat 15,15 and 16, 16 Fig. 2. The lower gears 15, 15 of eaeh pa r are mounted on a horizontal drive "shaft 17 which in turn :isjournaled in bearings 18, 18 in the standards 11, 11 respectively. The shaft 17 at one end has an extension 17 a for coupling thereto a power'drive (not shown) in l v to iig 2 is a front elevational view thereof; and l of any suitable well known construction. Supported above shaft 17.is aniupper shaft 19 journaled in a pair of vertically movable bearing blocks 20, 20?, mountedover the bearings 18, '18 in the standards 11,, 11. The

shaft-s 17 and 19 carrythe usual wringer rolls 21 and 22 respectively.

Mounted on the front and 'rear sidesofvthe gear casings 14, 14 are brackets 23 and 23?" which are adapted to removably supporta guard member 24 therebetween, .Said member' 24 is provided with a slotted portion 24? to permit feeding therethrough the clothes to 'be wrung, the flanged sides 24 of said member serving to prevent the accidental:in-

sertion of the operators fingers between the rolls 21 and 22. l a

The bearing blocks 20 and 20 are each recessed as at 20 to provide seats for the lower ends of the- tension springs 25, 25 The upper endso-f saidsprings are preferably,

disposed insimilar invertedrecessed portions i i 26, .26 preferably formed integral with the pressure end portionsofa tension bar 27..

For tensioningthe rolls .21, 22, pressure is a plied .to the'bar 27 by ,means of any suit-V a le adjustingmeans sueh aslscrew 28 which is threaded through the cross member 13 midway the ends thereof.

The means for-operatin the wrin I ers will. now be describe- ,Stradd ing the end 13*;Ofthe cross member 13 are the keepers 30,130 preferably taking thefform of-a U.

Said keepers extend downwardly over the cross member 13 and arepivotally secured as at 31, 31 to the standards 111, 11. A hand. lever32 is provided which maybe pivoted by meansof a pin 33 .to cross member 13 Thishand leverforms part of a togglev linkage ,comprisingta pair of link arms 3 1,34

connecting the keepers 30, 30V respectively thereto. The arm 3,4,ispivotally connected/to the lower end of the lever 32 and is pivoted at. the other end to the keeper 30. Thearm 34 is pivotally secured to the lever 32 above tions13 of :the cross member 13 preferably form integral outwardly extendinglramps over which :the :keepers3O 3O ride as will to prevent horizontal shifting oiythe-olgos's bar 13 with relation "to'the standardflll, 1.1 may be provided as, for example, vertically extending ridge projections 13 on said bar 13.

.hereina-fterappear. Suitable guiding means i The operation for separating or releasing the rolls will now be clear. \Vhcn the lever 3:2 in an inclined closed position, as shown in full lines in Fig. 1, the keepers 30, 30 straddle the cross member 13 inwardly of the ramp ends 13, thus holding the tension 1 527 down and con'ipressing springs 25, The wringcr rolls are then in operative position and under proper tension adjusted by screw 2Q. It the operatofis hand or an object be caught between the rolls, he quickly strikes the hand lever 32 throwing it into open or vertical position, shown in dotted lines in Fig. 2. The link arms 84-, 34 con neeted to the hand lever will then push outwardly on the keepers 30, 30 causing them to swing out oi their holding position to tree the ends of the bar 13, thus releasing the latte and the pressure bar 27, permitting tree upward movement of the bearing blocks 20, QOFtogether with the shaft 19 and roll 22 to tree the hand or object caught between the rolls.

To reset the rolls 21, 22 to their eti'eciive position, the hand lever 32 simply swung down to simultaneously restore both kii- epers 30, 30 to the position for retaining the ends of the cross member 13. In said return movement of said keepers, the hight portion of the U structure is 21(lz11)t6tl to ride on the ramp ends 13" of said member 13 whereby the latter is torced down to compress the springs 25. 25 the desired amount.
