This invention relates to an improvement \in clothes wringers, more particularly. to va `combined wrin er roll-guard and stripper.

It is among t e-fobjects of the invention to provide 'an attachment for 'wringer rolls aving the combinedv function of a guard and roll ystripper and which shall be ada ted for use on any clothes wringer wit out modifying the wringer structure and which shall require no, alterations or special appliances in the wringer per se for its application and use. l

Another object of the invention is to provide a wringer roll guard and stripper of,

the above designated character which shall be in the nature of an appliance designed toy constitute an independent element that may be readily placed on the roll or removedv therefrom without requiring it to be attached or in any manner supported on the wringer frame.

Another ob]ect of the invention is to 'provide a wringer roll guard of simple mechanical construction which'shall be relatively inexpensive to manufacture and which shall function to prevent the adherence of clothing to the wringer roll whereby possibility of injury to the fabric 4and breakage of the wringer mechanism becomes very remote.

Heretofore variousv provisions have been made to provide guards and strippers for wringer rolnls to'prevent injury to the erson feeding clothing therebetween, an to prevent the clothingVV 'from clinging or adhering to the rolls whereby they arewrapped around one of the cooperating roll members.

Guards and stri pers as heretofore con` structed are in the orm of sheet metal members of arcuate shape which are adapted to be attached4 to the-'wringer frame in some manner to secure them in the proper position to cooperate with the wringer rolls. The prior art devices were either .complicated in their3 structure which enhanced their cost of manufacture or they were required to be built into the wringer frames or fastened with special bracketswhichrestricted their use.

In accordance with the Apresent invention the wringer guard and roll stripper is constituted a self-contained member which is mounted in proper vcooperative'relation with the wringer Nrolls by simply placing the guard thereon. The guard is formed of sheet metal to constitute a yielding structure which is provided with a plurality of rolls that are adapted to cooperate with the sur- 'face of the wringer rolls to maintain 'the' guard in its proper operating position. The construction of 'the guard is such as to permit'placin'g iton the-'rolls or removing it therefromatthewill of the operator wlthout the need of tools or skill.

'In the aecompanaying drawing constituting a part hereof-and in whichl like reference characters designate like parts, Fig, 1 is a view inperspective of a clothes wringer having a portion of one lof the frame members brokenV away which embodies the principle of this invention; Fig. 2 a diagrammatic view illustrating the position and cooperative relation of a pair of wringer rolls and a wringer guard and stripper in accordance with the present invention; Fig. l3 a similar view illustrating a modified form of guard 'and stripper; and Fig. 4 illustrates still another modified form vof the invention.

y,Referring to the several figures of the drawing,l the structure therein illustrated comprises a wringer frame 1, having vertical side frame portions 2 provided with fixed journal bearings 3 The side frames 2 are further provided with slotted openings 4 for receiving movable journal bearing blocks 5. The stationary and

movable journal bearings

3 and 5 are adapted to receive the.

journals

6 and 7 of a pair of cooperating wringer rolls 8 and 9.K The wringer roll 9 is ad- 'ustable vertically in the frame portions 2 y manipulating the wing nuts 10 that coends of which are secured to the movable Journal'blocks to raise and lower the same. Mounted on the upper roll 9 is asheet metal bracket 12 of'arcuate shape compris- -mg two portions of the same form and di- Y voperate with the threaded members 11 'the eliminated as this has nothing to do with the r function of the device. v The guard member 12 ,at its free ends is shaped in the manner shown in Figs. 2, 3 and 4 to provide a flange ,element or stripper 16 that is adaptedy to engage the face of the wringer rollv 9. The flange 16 is bent at an angle from the 'straight portion 17 that diverges from the arcuate portion of the guard and the forms illustra'ted in the several figures are designed to produce a spring action to exert a yielding of guard shown l 16 will abut pressure thereon.

The ends of the guard are provided with upstruck portions 18 to which are secured rolls 19 the latter being journalled for rotation by pins 20 that are secured to the up- 3 two of such rolls are provided for a purpose as will be hereinafter explained, and in Fig. 4 the portions of the guard Contactin with the rolls are shaped to constitute strippers that engage the roll nearer the bite of the rolls than the corresponding element in the type in Figs. 2 and 3. The purpose of the construction and function of the guard is otherwise the same.

The guard members 12 are assembled on .the upper wringer roll 9 by joining them at their flanges 13. The flanges are secured by a thumb screw 2, or in any other suitable,

manner to constitute the sections 12 a unitary member.

When the guard is assembled, the flanges the roll 9 exerting a yielding The pressure on the flanges 16 will cause the entire guard 12 to rotate in the direction of rotation of the wringer roll until one set of guide rolls 19 engage the bottom wringer roll, the guide roll contacting with the bottom wringer roll in accordance with the direction of rotation of the wringer rolls. example, the/roll on the right hand side of the vertical center line passing through the rolls contacts with the bottom wringer roll 8 which indicates that the upper roll is rotating in a clockwise direction, this also being true of the illustration shown in Fig. 4. It willvbe noted that the bottom rolls 19 clear the upper wringer roll 9 and the rolls 19l that contact with the upper roll 9 clear the bottom wringer roll 8. With this disposition of the guide rollers 19 the guard may be slightly tilted but for all practical purposes it may be considered as symmetrically disposedl.with respectlto the vertical center line of the wringer rolls.

In Fig. 3 two sets of rolls 19 are employed to secure the guard member in its proper cooperative relation with the wringer rolls, and by the use of double guide rollers the latter may be made to contact with the upper and lower wringer rolls since there is no interference caused by the rotation of the wringer rolls in opposite directions as is the case when but a single group of guide rollers are used. v

When clothing is fed-to the bite of the As shown in Fig. 2 :for f,

rolls the extended portions of the guard will prevent the operators hands from getting dangerously near to the roll bite. Thin and delicate fabrics and fabrics of fine texture having a tendency to adhere to the upper wringer roll will be pushed out or peeled ol' the roll by the strippers 15 which prevent the clothing from being Wrapped around the roll.

It is evident from the foregoing description of this invention that wringer roll guards and strippers made in accordance therewith comprise a simple attachment that may readily be placed in its operating position by anyone, and it will also be apparent that the simplicity of the device makes it relatively inexpensive to manufacture and that it is adapted for production in relatively large quantities.

I claim:

1. The combination with a er rolls, of a combined detachably mounted on rolls and comprising a ment having oiiset portions adapted to engage one o the wringer rolls, said guard and stripper being provided with guide members bearing upon the rolls to maintain it in its proper operative Vposition with relation to the rolls.

2. A combined guard and stripper for wringer rolls comprising a flexible member having extending portions adapted to yieldingly engage one of a pair of cooperating roll members, and having a plurality of guide rolls mounted on the guard member to maintain the same in itsproper relation with the roll.

3. A combined guard and stripper for l wringer rolls comprising a sheet metal member having the extended end portions thereof angularly disposed, and provided with flanges for enga ing one of the roll members, said guard eing provided with means cooperating with the wringer rolls for maintaining it in its proper cooperative relation with the said wringer rolls.

4. AA combined guard and stripper for wringer rolls comprising a sheet metal member having the extended end portions thereof angularly disposed, and being further provided with u struck portions for securing a plurality o guide rolls that are adapted to contact with the wringer rolls to prevent the guard member from turning with the roll.

In testimony whereof, I sign my name.
