21 claim.

The present invention relates to wringer constructions and more in particular to wringer constructions having novel means for preventing injury to the operator or attendant.

Among the objects of the present invention is to provide a novel wringer construction in which certain of the rolls are releasably mounted so that the same readily separates when an excess .of pressure is applied thereto, as for example, should any part of the operators body or clothing become engaged therewith, or should there be an undue bunching or congestion of the clothes passing therethrough.

I'he invention comprehends the idea of providing a construction inA which the rolls are readily separated and released from their normal operative wringing contiguous position, should excess pressure be applied because of the above condition, and remain in this position until the same are manually returned into their former position.

Another object of the invention is to provide a wringer construction in which one of the rolls is swingably and releasably mounted in the frame thereof, means being further provided whereby a release of this roll may be effected either manually or by Aan excess of pressure applied to said roll.

The invention further comprehends the idea of providing a wringer construction in which an upper and lower bite is formed between rolls, whereby clothes passing therethrough .are com- -pressed and amply wrung in their passage through the wringer.

A further object of the invention is to provide a wringer construction in which certain of the rolls forming these upper and lower bites are releasably held in their normal operative wringing position' and are maintained in this position during the wringing operation unless the clothes or the rlike passing therethrough become congested or bunched, or the attendants body or clothing becomes engaged therebetween, at which time the rolls would be released due to the excess pressure applied thereto, thus preventing injury to the attendant or his clothing. Novel means are provided whereby the rolls remain in their released position until the same are manually returned to their normal operative position.

Still another object of the invention is to provide a wringer construction in which the bite between certain of the rolls may be varied so as to adapt this wringe'r for effective operation under various conditions and toadapt the same for handling all kinds of material.

(C l. (is-248) The invention still further contemplates the idea of providing novel means for guiding the clothes or other material in their passage through the wringer.

Other objects, features, capabilities and advantages are comprehended by the invention as will later appear, and as are inherently possessed thereby.

Fig. '7 is a diagrammatic view of the rolls when in their normal operative position and showing in full line the position of the rolls when the same have become separated.

mferring now more in detail to the drawings, an embodiment of the present wringer construction I selected to illustrate the invention is shown as being secured to a gear housing 2 enclosing mechanism (not shown) driven by a suitable source of power (not shown) for driving the rolls thereof. This gear housing 2 is suitably mounted upon the tub 3 of a washing machine.

The wringer construction l comprises a frame 4 having an arcuate shaped rear backing member 5 tothe ends of which is secured the upright end frame members 6 and 1a having rolls 1, 8, and 9 mounted therein. The end frame members 6 and 1 are of substantially the same construction their upper ends.

and comprise an inner member lil and an outer or end plate Il secured together as by bolts, screws or the-like.` The roll l comprises a central shaft I2 having one end thereof extending through the frame member 6 and normally in operative engagement with the' gear mechanism in the gear housing 2 whereby the same is driven while the other end of this shaft extends through an opening in the inner plate l0 of the other frame member and is adapted to be journalled in the bearing I3 provided on the end cover plate l l.

This power driven roll l is adapted to frictionally drive the roll 8 having a central shaft lll extending through openings l5 in the inner plates I0 of the end frame members, the ends of this shaft being mounted in the bearing blocks I6 slidably mounted within the grooves, such as l'l, provided in both the inner and outer members l@ and ll 'of the end frame members. These bearing blocks are of abox-like construction, and eX- tend throughope'nings IS in the end frame members. Each/of,l these bearing blocks is provided with a thumb screw i9 threaded in the front end wall thereof yand is adapted to bear against a plate 20 for compressinga coiled spring 2l mounted in the bearingblock and between ,the plate 2l) and a tensioning block 22 adapted topartially encompass the ends of the shaft I4. When this roll 8 is in its normal operative wringing position contiguous with the drive roll l, the amount of bite between these rolls may be readily adjusted by way of these thumb screws i9. Each of these bearing blocks I6A's provided with rearwardly extending lugs 23 having a rod 24 extending therebetween fora purpose to be later more fully disclosed. f f

The lower roll 9 isV adapted to be driven by the intermediate roll 8 and is provided with a shaft 25 having its ends projecting through and movable in the arcuate shaped openings or slots 26 in the member l0 of the end frame members. The ends of this shaft 25 are mounted in the end of the arm members 21 mounted on the ends of the shaft l2 of the power driven roll 1. Each of these arm members 21 has an upwardly extending portion 28 movable within openings 29 in the end frame members' and are connected together by means of the rod 29a mounted in By movement of this rod 29a either ina forward or reverse direction, the lower 211 9 may be moved in the arcuate shaped slots When the intermediate roll 8 is moved in a rearward direction into Contact with `the driving roll 1, the bearing blocks I6 are moved into a position as clearly shown in Fig. 5 of the drawings. If at this time, the arm portions 28 are moved in a rearwardly direction as also clearly shown in this gure of the drawings, the lower roll 9 is moved upwardly in the arcuate slots 26 into contacting engagement with the intermediate roll 8. WhenV the arm members 21 are in this position, lugs 29b.which are provided thereon, are

Yadapted toengage with the rods 24 of these bearing blocks for maintaining both the lower roll and the intermediate roll in their operative wringing position.

Should any part of the body or clothing of the operator or attendant become engaged between the rolls 8 and 9, or should the clothes passing therebetween become congested or bunched so as to cause an excess of pressure to be. applied tothese rolls, the lower roll 9 is forced downwardly in the arcuate slots 26 to a point where the lugs 29b become disengaged from the rods 24 whereby the intermediate roll is free to move in an outwardly direction. The separation of the intermediate roll 8 from the power driven roll "l not only permits the operator to remove any part of his body, such as his hand or the like from between the rolls, or to remove any congestion or bunching of the material passing therethrough, but likewise breaks the driving connection between the power driven roll l and the other rolls. These rolls will remain separated until such time as the intermediate roll 8 is manually moved in a rearward direction, and the lugs 29b are move-d into an engaging position with the rods 24 by means of the rod-29. It will be also noted that when the lugs 29b are in engagement with the rods 24, the lower roll 9 is simultaneously moved into its normal operative contiguous position with the intermediate roll 8.

In order that the clothes or other material may be properly guided in their passage through the rolls of the present wringer construction, a guide plate 30 is provided and is secured by means of screws 3l or the like to a back plate or supporting member 32, secured as by means of screws 33 or the like to the arm members 2l. This supporting member 32 not only provides means for holding the guide member or plate 38, but likewise provides a rigid connection between the arm members 2l whereby the same may be moved within the end frame members simultaneously by manual operation of the rod 29a.

The clothes or other material which pass between the bite of the rolls 8 and 9 are guided in an upward direction along the guide plate 30 into the bite between the rolls 8 and "l. It will be Seen that the clothes or other material in their passage through the present wringer construction are amply and eiectively wrung.

A coiled spring 34 having one end mounted over a projection or boss 35 on the backing or supporting member 32 and its other end mounted in the bore of a plug 36 screwed into the back plate 5 is provided for urging the roll 9 into its operative wringing position and to assist in the movement thereof in the arcuate Slots 26. A thumb screw 31 threaded in the lug 35 and having a washer or the like (not shown) secured to the inner end thereof is provided for adjusting the tension of the coiled spring 34.

While I have hereindescribed and upon the drawings shown' an illustrative embodiment of the invention, it is to be understood that the invention is not limited thereto, but may comprehend other constructions, arrangements of parts, details and features without departing from the spirit of the invention.
