Application led May 25,

T0 all whom 'it may concer/m.' Be it known that I, FRANK B. Zinc, a citizen of the United States, residing at Fredericktown, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in VVringers, of which the following is a specification.

The invention relates to clothes wringers and more particularly to power driven Wringers used in connection with Washing machines. The invention has special relation to a safety device for the quick release and separation of the rollers incase of emergency.

A danger inherent in the ordinary type of power driven wringers is the liabilityv of injury to the operator by having a hand caught between the compression Kroll in feeding the .clothes through the wringers. Serious injury may thus occur before the driving mechanism can be disconnected. Similarly, the wringer mechanism may be broken by bunching of clothes in too great thickness to pass between the rollers. AThese conditions have 4necessitated 4the development of means for `quickly releasing the compression between the rollers and for permitting their separation sufficiently for the withdrawal of a hand or clothing caughttherebetween. Y

In the safety devices heretofore used, cere tain disadvantages of construction and uncertainties of operation have been present which I have overcome in my present inf vention. y

`One of the objects of my invention is to provide a quick operating roller releasing device which also operates to positively separate the lrollers when released.

Another object of the invention is to4 provide means for controlling the device which is conspicuously available to the operator in any position which the latter may be.

Another object is to provide a releasing device in which a unitary control is operable in one direction to release the rollers from tension and widely separate them, and by a reverse movement of the control to restore the rollers to operative position under tension as before. 'i A further object is to provide a safety device in which is incorporated means for tensioning the rollers and so constructed that the operation of the device does not normal l vice.

The .wringer is mounted upon a. swinging bracket 10 lwhichcarries a ygear box l1 housingl asuit'able gear mechanism adapted to drive the wringer rolls. The bracket 10 mayr be provided with' adepending ,tubular extension 12"thr ough which Aa drive`. shaft 13 may extend into the gear box for l"the operation vof the gear mechanism. -The tu; bular portion 12 may be'y adapted for 'piv otal mounting in a suitable support carried by the Washing machine. 2A hand Lleveitlt may be provided on the upper`- portion of the gear box Yforithe convenient Aoperation of `means controlling the engagement of the driving mechanlsm actuating the wrmger rolls.

A. pair of spaced journal blocks 1 5` and 116,

rising from thenpper surfaceof Lthe bracket tion at onev end with the gear, mechanism 10, carry the ends of the shaft 17 upon which is formed the lower roll 18 of the wringer, and serve as the Alower half of the journals for the respective ends of t-he roller shaft. The shaft 17 Ahas a suitable driving connechoused in the gear boX 11. Overlying and suitably secured to the journal blocks are' a pair of cross members 19 and 2O extending a substantial distance on both sides of -the journal blocks and forming attheir central portions journal fcaps 21 securing thejournailed ends of the roller shaft 17; Y

Positioned abovethcl cross `members r19 and 20,are 'a pair vof 'swinging bearing sup@ ports 22 and23, pvoted to the ends ofthe i cross membe'rson one sideo'f the wringer, as

l bearing slots 27 are. so positionedthat when the supports 22 and'23 are in'n'orma'ltpos-itionfthe upper roll lies immediately above the lower 'roll and incontact therewith. The supports 22 and 23 are adapted to swing upwardly about theirv pivots and carry the upper roll 26 a substantial distance/away from the lower roll 18. l

To secure theV rolls in normal 'relation with the necessary compression for the Yoperation of the wringer, I have provided releasable tension means con'iprising a'pair'vof upl 1 right rods 31 andri32 pivoted on the forked ends 33 and 34 of thecross members "'19 and 20( The rods 31 and* 32, rising from'the cross`inemb'eis'passf normal position between 'the bifurcated Vends 35 and 36 'of the bearing supports for the upper'rolls, andexi tend 'upwardly therefrom to the contro-l bar frigid'ly connecting the'two rods. 'l

7flach ofthe upright 'rods is screw-threadedl over its y'portion 'extending above the bifurf cated'end of the" bearing support, as atl 38,

i d' and has threaded thereon a hand wheel 39 abutting which is a coiled .spring 40 eXten'df ingjdownwardly about the rod. The lower end of the s rin'g 40 iscontined by a washer 41, limited 1n its downward movement by a cross pin42 fixed'iirtherod.l The crosspin 42 is located so that when the upright rod'is in engagement with :the bifurcated end of the'b'eari'nfg 'support in normal position,v the right rods.

pin is below the support.

upper surface of the bearing The. extremities of each ofthe bifurcated endportions 35 and 36 vof the bearing supports, areV constructed-with an inclinedl surface app-roachrngthe Vupper surface of the support, and so arranged that when the upright rods are swung into engagement with the ends of the supports, the washers 4:1 slide overy the inclined surfaces, thereby accomplishing the compression of the coiled springs in passing to their `normal position at rest upon the upper surface' of the bearing supports. `When so normally positioned, Y

the upright rods 'otherwise than b'y'a posi- I tive movement ofthe control bar. Y

`Y The construction here describedA provides for the positive securing Aof the upper lroll in operative relation 'to' the lower roll. Any desired degree of compression between ythe rolls may be secured by varyingv the 'tension ofthe. vcoiled springs through lvaryin'-g,the position of the hand wheels 39 upon the up'- 'VVit'hthe outwardV swinging of the control bar 37, the .tension springs arecarried out of engagement with the upper rollbearing supports, instantlylreleasine' the latter and perimitting theroll to be 'swung'upwar'dly away from the lower roll. Releasing the roll, how- "ever, doesnot disturb the adjustment of une spring tensioin vThe vstop pins 42 retain the spring adjustment and Ahold thefwashers 41 in' position for' reengagement vwith thefreabiove the rolls -tooffer no obstruction tov the ordinary use vof 'the wringer, andb-yreason of, its location, be reached 'by the operatorfrom any position fon either side of the wringer. A further advantage isv that the control'bar `extends over the entire' klengt-hv of the rolls. The long bar is' conspicuously outstanding and maybe grasped or struck to immediately releaseth'e rollers'in case .of 1

accident with-out searching able 'operatingdevei A` furtl'ier irnptntantv` advantagey in ymy construction Vresides in f'they lprovisionfof means forjpositivelylifting the upper roll for a less availbearing :supports aft-er their release.A 'By To accomplish these ends I have provided angular extensions 43 and 44 on the upright rods 3l and 32, extending below the cross members 19 and 20, and carrying at their extremities connecting links 45 and 46, the latter being pivoted at 47 and 48 on the upper roll bearing supports 22 and 23. rIhe connections between the extensions 43 and 44 and their respective connecting links include arcuately slotted portions 49 formed at the ends of the links. Pins 50 fixed in the extremities of the extensions 43 and 44 extend through the slots and carry suitable washers at their outer ends to prevent displacement of the links. 4

During that portion of the swinging movement of the upright 'rods 3l and 32 which carries the tension springs out of engagement with the bifurcated ends 35 and 36 of the bearing supports, the pins 50 slide through the arcuate slots without operating the connecting links. As soon as the tension springs have cleared the ends of the bearing supports, the pins 50 engage the ends of the arcuate slots and by continuing theswinging movement of the upright rods, cause the links 45 and 46 to force the bearing supports 22 and 23 upwardly about their pivotal supports upon the cross members 19 and 20. lVhcn in extreme outward position the weight of the upright rods and the control bar is sufficient to hold the upper roll in raised position. In the reverse movement of the upright rods forrest-eration of the rolls to operative position, the bearing arms are iist lowered so that .the two rolls are again positioned in operative relation,-

whereupon the cross pins 50 again travel the arcuate slots while the tension springs ride up over the bifurcated ends of the bearing supports to their normal operating positions.

It will now be apparent that I have provid-ed quick releasing means of very simple and inexpensive construction which securely holds the rolls in proper operating relation, under any desired tension until it may be desired to release them; and that the latter operation may be accomplished by asimple movement of a readily accessible control bar, thereby instantly releasing the rolls and positively forcing their separation. also be observed that the raising and lowering of the upper roll and its supports may be controlledentirely by the swinging of the control bar without necessity for sepa rately replacing the rolls after their release.
