WBINGEB ROLLS FOB CLOTHES W RING-BBS.

Application filed September To all whom it may concern.

Be it known that I, Grosmvr. H. JANm, a citizen of the United States, residing at WVyoming, in the county of Hamilton and btate of Ohio, have invented certain new and useful Improvements in Wringer Rolls for Clothes Wringers, of which the followin is a specification.

t has been a usual practice heretofore in making clothes wringers to rovidethe shafts of the wringer rolls w1th meshin' cog-gears so as to drive one wringer rol shaft from the other wringer roll shaft. This has been done to provide a positive driving connection between the wringer rolls. It has been found in practice that, if the wringer rolls, as heretofore constructed, receive a coating of soapy slime, as happens in the use of the wringer, the driving wringer roll will, in the absence of such meshing gearing between the wringer roll shafts, fail to afford suflicient traction for the opposed wringer roll, to rotate the latter, with the result that, if it is attempted to put clothes between the wringer rolls,

the wringer rolls will not grip the clothes to draw the clothes between the wringer rolls, but the driving wringer roll will merely turn without having tractive force either upon the opposed wringer roll or the clothes.

It is the object of my invention to so construct the wringer rolls, as to insure tractive force between them in the absence of mesh- It is the further object of my inventionto provide wringer rolls with coacting tractive sections arranged to drive one wringer roll from the other wringer roll, and, further, to provide the wringer rolls with portions whose primary function is to maintain drlilving' relation between coacting wringer ro s.

The invention will be further readily understood from the followin description and claims, and from the drawlngs, in which latter:

21 represents a usual frame of a clothes 35 wringer which ma be of suitable construction. rin er ro are usually arranged in pairs in t e clothes wringer. Suitable means are provided for imparting rotation to one of t e wringer rolls. These means 00 may be manual means or power driven means, as may be desired.

I have shown power driven means comprising a bevel-gear 22, which is driven for instance by a shaft 23, journaled in a bear- 96 ing 24, and meshing with bevel-

gears

25, 26, normally loose about the shaft of one of the wringer rolls.

A clutch-collar 28 has spline connection 29 with said shaft, the said clutch-collar and lot the respective bevel-

gears

25, 26, being provided with the coacting teeth of clutches 31,

' bearings 44 in the frame, and the shaft 45 of the wringer roll 42 is arranged to rotate in bearings 46. The bearings 46 slide in guideways 47in the frame. Pressure means are provided for exerting pressure between the wringer rolls when wringing clothes.

A spring 48 may be employed to exert this pressure, being shown adjustable by means of a screw 49, threaded in a bearing 50 on a cross-bar 51 of the frame. The mounting, driving and pressure means may be of any usual or desired form or construction.

I have dispensed with the usual cog-gears between the wringer rolls. In order to insure driving relation between the coacting wringer rolls, I provide the wringer rolls with tractive portions which engage each other to coact for insuring frictional driving relation between" the wringer rolls. These tractive portions may assume different forms, and I have exemplified five such forms in the drawings. It is obvious that the various forms may be employed coactingly, or one form may coact with another, or one or both ends of the wringer rolls may be provided with my invention, or

. other changes be made, without departing from the spirit of my invention within the scope of the appended claims.

Referring to Figs. 1, 2, 3 and 4, I have provided the wringer roll with a tractive section 55, exemplified as arranged about the axis of the wringer roll, andformed in the material of the body, for instance, rubber, of the wringer roll. One of these tractive sections is shown located at each end of the wringer-roll. This tractive section or roughened section of the wringer roll is exemplified as recurrent protuberances or ridges and grooves, arranged about the axis of the wringer roll, at the end or ends of the wringer roll. They form tractive transmission sections of the rolls to transmit rotation from one of the rolls to the other of the rolls.

Referring to Fig; 1, the tractive sections, whatever their form, may have shields 57 received thereover, the shields being suitably secured to the frame of the machine. End collars 58 are provided on the wringer-roll. Each of the end collars is shown located on a reduced annular step 60 of the shaft, against an annular shoulder 61 formed by upset, as shown at the roughened or ribbed tractive sections will cause rotative tractive transmission from one of the wringer rolls to the other of the wringer rolls, with sufficient force to cause a piece of fabric or clothes to be gripped between the wringer rolls and to draw the same in between the rolls.

When the clothes have been once gripped between the wringer rolls, the clothes act as a medium to cause transmission of rotation from the driving wringer roll through the clothes to the opposed wringer roll for maintaining rotation of the opposed wringer r011 when once the clothes have been started between the rolls.

The presence of the clothes causes a relief or separation between the tractive sections and relieves these tractive sections from wear, the tractive sections being preferably protected from contact by the goods by the shields 57. The principal wear upon the wringer rolls takes place in those portions thereof which are contacted by the clothes,

and serve to express the water from the.

clothes, and, as most of the rotation of the wringer roll takes place while clothes are located between the rolls, the driving faces of the tractive sections of the wringer rolls are preserved, and maintenance of contact between coacting tractive sections is as-' sured, due to the greater wear of the expressing portions of the rolls.

I have in Figs. 5 and 6 shown a similar form of tractive section 65 for the rolls, com prising ribs and spaces between the ribs, similar to the ribs and spaces of the tractive transmission section 55, the circlein which the crowns or outer peripheries of the ribs is located, being of greater diameter than the cylinderof the roll. In this construction greater pressure is brought to bear between the tractive sections of the rolls when the wringer rolls are in coactin pressure relation, for aifordin additiona tractive force.

In the forms s own in Figs. 1 to 6 inclusive, the tractive sections are shown as integral with the body 53'of the roll, being formed for instance by forming the mold in which the wringer roll is molded with counterparts of the ribs and spaces between the ribs, soas to form the ribs and the spaces between the ribs, on the rolls at the same time that the body of the roll is formed, and of the same material as the material, for instance, rubber, of the body of the roll, the whole being vulcanized together to, form an integral structure.

In the form shown in Figs. 1 to 6 inclusive there is pressure brought to bear between the tractive sections of the coacting rolls to cause tractive transmission of rotation from the driving wringer roll to the driven wringer roll. This pressure is greater in the form shown in Figs. 5 and 6. The pressure tends to resiliently flatten or distort the tractive sections one upon the other for enhancing the tractive transmission, as clearly shown in Figs. 3 and 4, and in Figs. 5 and 6.

I have, in Figs. 7, 8 and 9, shown a further modification, in which the friction or tractive transmission section of the roll comprises a band 75, this band bein shown of slightly greater diameter than t e body 73 of the roll. These bands are referably of a softer or more yielding rub r than the rubber of the body of the roll, but are preferably vulcanized with the body of the roll, so as to firmly adhere thereto or become amalgamated therewith and form an integral structure, one or both ends of the rolls ma be provided with these bands.

lz'hen pressure is applied between the rolls in this exemplification of my invention, the friction bands are com ressed upon the respective bodies of the ro ls for resiliently flattening or distorting the contact portions of said bands and compelling tractive transmission of rotation from the driving wringer roll to the driven wringer roll 10 means of said bands. The distortion of t e band is communicated somewhat to the body of the roll, all as clearly shown in Figs. 7, 8 and 9. In this form also there is separation between the wringer rolls when the oods have been received between the wringer rolls, thereby relieving pressure between said friction or tractive transmission sections.

I have, in Figs. 10 and 11, shown a further modification in which friction bands 85 are employed which are received in rabbets 86 in the ends of the bodies 83 of the'wringer rolls. These bands are preferably of softer or more yielding rubber than the bodies of the rolls, and are preferably vulcanized in said rabbets, so as to become amalgamated with said bodies, and form an integral structurewith the bodies. They preferably extend radially beyond the periphery of the bodies of the rolls for having firmer contact when pressure is brought to bear upon the rolls. One or both ends of the rolls may be provided with said bands.

The compressive action upon said bands extends into the cylindrical projection of the rolls and the distortion extends over a great; er area and to a greater depth radially than in the form shown in Figs. 7, 8 and 9, thereby lending additional traction between the rolls, which distortion or action of the tractive transmission portion is clearly indicated in Figs. 10 and 11.

I have in Fig. 12 shown a fornrsimilar to that'shown in Figs. 10 and 11, with this addition, that the bands 95 are provided with peripheral protuberances 94, shown as ribs and spaces between the ribs, the band being otherwise similar to the band 85, and received in an annular rabbet 96 in the body of the wringer-roll, the expressing section of which is indicated at 99. The band is preferably vulcanized to the body to form an integral structure. The resilient protuberances aid in the tractive transmission of rotation between the wringer rolls.

.Havin thus fully described my invention,
