STRIPPING MECHANISM FOR WRINGER-ROLLS.

Application led October 2, 1919. Serial No.

To all whom z't may concern:

Be it known that I, THOMAS J. BONNI- wnLL, a citizen of the nited, States,and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stripping Mechanism for lVringer-Rolls, and l do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.y

This invention relates to an attachment for a wringer to provide a means for preventing articles after passing between the wringer rolls from around either thereof by stripping or diverting the articles from the rolls if any tendency for the articles to cling to the rolls occurs.

lt is-an object thereforeof this invention, to construct a wringer having a plurality of adjustably mounted stripper bars adjustable to any position according to wearing of the rolls, for contact with the wringer rolls on efectually prevent adhering of articles to the rolls for either direction of operation thereof. Y

@ther and furt-her important objects of this invention` will be apparent from the disclosures in the ldrawings and specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

becoming wrapped ,Y

each side of eachroll toV rolls 3 and 4 in a usual and well known manner. vThe shafts for the wringer rolls are provided with intermeshing pinions 5 and 6, to insure positive and simultaneous operation of both rolls in opposite directions when one thereof is operated in the usual manner. by means of a crank placed upon the shaft extension 7. A water drain board 8, is mountedbeneath the lower roll in a usual,manner.

Secured between the uprights 1 and 2, on each side of the wringer, Aare transverse boards 9, positioned slightly above the upper roll 3, and transverse bars 10 are also secured on each side of the wringer to the uprights 1 and 2, slightly below the roll 4.

The stripper bars for the upper roll are shown clearly in Fig. 2, and are designated by the reference numerals 11. rlhey are preferably. though not necessarily, constructed of wood, but ofcourse may be of metal or other material. having beveled lower surfaces which rest by gravity upon the top surface of the roll 3.' At each end of each of the stripper bars 11, transverse pins or rods 12 are provided, extending therethrough so that the bars are loosely retained thereon, permitting adjustment of the stripper bars also tolt any size roll. vSaid rods 12, have no connection with the wringer frame, but merely abut against the bars 9, and prevent overturning of the stripper bars 11, resting by gravity on v`the roll 3 when the roll 3 revolves. .As shown, the uprights 1 and 2 are provided on their inner surfaces with angle irons 13, which constitute a part of the usual Awringer constructions. IThe stripper bars 11, are provided with block sections or extensions 14 at their ends, which 'are squared off to rest in the upright angle bars 13, and serve also to prevent overturnin of the stripper bars 11 on the wringer rol.

Beneath the lower wringer roll 4, another set of stripper bars 15 is provided, which at their ends are loosely engaged on transverse rods 16, looselyA mounted in the -Wringer frame,

and abutting the boards 1.0. For the purpose of retaining the lower stripper bars l5 `upwardly in contact with the undersurface of the roll 4,a pair of springs 17 are provided for each of the ystripper bars, bearing upwardly therebeneath near Patented Apr. 119, 1921. A

each end thereof and secured in position on the respective boards 10.

I Operation.

The upper stripper barsA 11, rest upon the top roll 3 by gravity, the beveled lower surfaces thereof riding upon the surface of the roll. The rods 12 which extend loosely Vthrough each end of the stripper bars 11,

prevent overturning thereof, and said rods atitheir ends abut against the boards 9.

In some types of wringer constructions, the boards 9 are omitted, but generally the upright angle irons 13 form a part of this structure, and these may be utilized to prevent overturning of the stripper bars 11. Accordingly, I haveshown block sections 14,.l secured to or forming a part of the stripper bars 11, engaging loosely in the upright angle bars turning of the stripper bars. rods'12 may be used, or the angle bars 13 and block sections 14, toprevent overturning of the stripper'bars, butthis will depend upon the type of wringer with which the stripper bars are associated. l

Similarly the lower stripper bars 15 contact against the under surface of the roll 4, and are held thrust upwardly against the roll by the leaf 0r any other type of springs 17, securedA to theboards 10. .Similarly the transverse bars 16, loosely engaged through the stripper bars 15, prevent overturning of the stripper bars by rotation of the roll.

It is obvious that many ,other ways and means for disposing, attaching or assembling the stripper bars with the wringer are possible whereby the stripper bars are held in operative relation by gravity or resilient means, and capable of displacement movement from the' rolls, but all such'modifcations fallwell within the scope of my invention.- In place of 'two stripper bars 13 and serving to prevent over Either the.

f substantially to the contour of the roll at its contacting portion therewith.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

Claims.

1. In a wringer, the combination with the rolls thereof, of stripper bars contacting with the rolls, and means for securing said bars in place, comprisinga transverse rod at each end, extending transversely through said bars, to non pivotally secure said bars within the wringer frame.

2. In a wringer, the combination with the rolls thereof, of a pair of parallel stripper baars arranged to Contact with each roll, a.

. date the same for different sized rolls and to take up wear.

In testimony whereof I have hereunto subscribed my name in the presence of4 two subscribing witnesses. i
