Patented Sept. 21, 1943 WmNGn I charles W. williams, o1eve1anaohi0, assigner to, Automatic Safety Wringer Company, a partnership i ApplicationMay 19,1937, seriaiNo. 143,521 f '24 claims.

This invention relates to a clothes, wringer designed from the standpoint of affording safety to the operator as well as from the standpoint of eiciently wringing clothes orany other suitable object passed therethrough.

The wringer is of the multiple roll type in which two rolls are used to effect a wringing action and the third roll provides an intake bite f which guards the operator by preventing passa-geef the hand into the dangerous pressure roll bite. Mechanism is provided in my improved wringer to stop the operation of the same when material exceeding a predetermined thickness is fed to the intake bite. In this manner ifv the operators hand should be caught in the pressure roll; bite and drawn into the wringer the thickness of the hand will act to stop the operation of the Vdev1ce.

I prefer to employ three rollsin my improved wringer', locating them in such manner that the top roll contacts both of the otherrolls. Pressure is interchangeably applied to the bite formed bythe toproll and either of the other rollsdesired. In each case thethird roll then acts with the top or common roll to provide the intake bite.

In general the objects of my invention may be said to embody the construction of a multiple rollwringer which wrings clothes efliciently, affcrds vadequateprotection to the operator and is simple in construction. Other objects of myy invention will becomeapparent from the description following when read in conjunction lwith the drawings appended hereto. The important features of my invention are' summarized in the claims.

In the annexed drawings: Fig. 1 is a front elevation'showing the genera construction of my wringer;

Fig. 2 is a downward View showing the wringer with the parts exposed by Vopening the top;

Fig.j3 -is 'a vertical section through the `wringer; Figs. 4, 5 and aresections throu'ghFig'j-Sjas indicated by the lines 4-`4, 5 -5 and` 6-5 respec-.- tively. ,i v` Referring now to the drawingsand more particularly to Fig, 1 my wringer [comprises a bodylil carrying a top l2 and mounted on ahead `l5, having'Y an operatirigjdrive I6 connecting with an ordinary'ty'pe of washing machine wringe'r post.

The power head 'of my wringer isof a type well known in the art and is best shown in Fig. 3. The

power connection I6 comprises the downward end of a `st ubshaft l1 carrying a .bevelgear 2( l. Continually in engagement with.A the. gear are two bevel gears-23 and' 24 idly ca ."rried ongamstub shaft` 25. The inner end of the stub shaft carries ak gear 30. Slidably secured `to the shaft 25 is a c1utch.28 operated by a handle 29 Vand movable intoengagement witheither of its adjacent bevel gears', ask desired, `to establish a drive at theV .gear 30 which may be 'either clockwise or counter-clockwise. i ,A

Of the three rolls in my wringer, the uppermost one is power driven.` Still referring -to Fig. 3, Athis top roll, designated at 35, is carried in a pair of bushings 31 and` 3 3, veach of which is secured by respective stirrups i0 against journals42 integral with the top` I2. At the leithand end of the shaftl ofthe roll 35 (Fig. 3) there issecureda gear 45, the rotationof which revolves the aforementioned roll.

The gears" 3 0 and 45 are operatively connected byan ,intermediate gear 50. This gear, asshown in Figs. '2, 3 and 4, is carried on a short stub sha-ft 52 Vwhich inf-turn ismounted in an arm 55 and whiclris idly carried at the left-hand end of the bushing 31,;11; `will ythus be apparentthatwhen the -three gears Aaremaintained in operative relation-tol each other; the roll 35 will. be drivenby-rotation of the connection I6. This means of retaining the member 55 will be hereinafter described. i 1 Theroll35coacts with'a pair yof lower rolls 60 and fxf'ffhese latter vrolls are rotatably carried at their yends byrespectivebushings 61, which in turn are rotatably carried in roll blocksl.- V.The bushings ar e sogcarried to permit the blocks 10 torokreely. when one pair of bushings are carryingthe pressure spring load. Referring to Fig. 2, it will be seen that the bushingsl terminate adjacent the rolls in an inner angedportion, `one face of which bears against Aa cross-rib H of the body portion` lil.y Thus the ared side portions of the ,two bushings 6l carried on gopposite ends of a lowerv roll shaft prevent axial movement of the rollsby abutting the 'aforethe .ribs filare" cut out adjacent their mid-section to permit freeupfand down motion of the rolls =and65 in the roll blocks 19. The roll blocks ,10 are normally prevented from downward movement by the action of aV pair of light springs 'l5 which, at their top, liein a cupshaped part ofthe blocks 'l0 and at the bottom overlie apin-shaped projection at the lower edge ofthe rib'll (seeiFig'. 6).` l

. Wringing pressure is applied between the roll 35 and either of the other rolls desired by pressure springs 80, as best shown in Figs. 3 and 5. These springs are restrained between a pivoted block bushing of either of the lower rolls desired. As shown in Fig, 5, this comprises a pair of re-f cessed cam edges 96 in eachblock, thefrightfv hand surface being adapteditoengagethe. rigidi-Q y hand bushing 61 and the left-hand surface the It will thus be apparent that when the two spring assemblies,-as shownfinFig. 3, are moved to underlie the bushing of-,the `roll i left-hand bushing.
