UNITED STATES `silicon* n. scnnonnnn, or NEWTON, Iowa i SAFETY wamenn Macnnmsm Application mea January 14, 1924, serial No. 636,120. 'renewed septemter as, 1927.

My invention relates mainly tol wringer mechanism and more particularly to a safety vwringer mechanism.

lThe object ofl inyanventio'n is in the pro-` v vision of a safety wringer having a quick release mechanism adapted to relieve the pressure from the upper'wringer roll andy also to re-set said roll again in operative position without further adjustment of the l pressure means.

Other objects of my invention will appear in the following specification taken ,in con-4 nection with the annexed drawings in which r Fig. 1 isa sidev elevation of my wringer, l portions thereof being shown partially in section for a more detailed disclosure;

Fig. 2 is an end elevation ofl my device, showing the quick release member in several of its positions.

Fig. 3 is a sectional view taken on the line 3---3v of Figure 1. i

Referring to the specification, I have shown a base portion of the wringer made up of the following parts.

End portions and 11 are of stamped metal, shaped or fashioned to receive the bearings for the lower roll, saidend portionsbeing either connected in a positive. manner to a lower frame or base 12 formed of stamped 30 metal shaped vin a manner, not only to provide a substantial connecting means with the conventional washing machine but also toihouse therein a tensioning spring, later 't0'- i be described. :5 This base late 12 as clearly seen in Figure 1, provi es the connection between the ends 10 and 11, which as a whole make up the main frame portion of `the wringer.

Attached at each end to the endl plates l0 o and 11 are two transversely positioned guard melinbers 13, which lie adjacent the lower ro It may vbe seen at this timen that the upwardly projectingI ends 14 of fthese guard members are fashioned in such manner aav to prevent any arment passing through the wringer from eing caught in any manner in the bearings or drive portionsthereof. The above is a well known constructien 5o and co-operates with'the inwardly projecting portions 15 on the end plates to assist -the entrance and ejection of clothes from the wringer. l

vTwo wooden bearin s 16 are housed within the end portions, a utting at their lower sides thev top of thebase plate 12. These ment of the upper and lower rolls the a formal bearing members support the projecting ends of the lowerwringer roll 17.

This vlower wriger roll is power driven in the usual manner from Ithe washing machine throughthe connection 18.

An auxiliary frame member `co-operating with the main frame portion is made up of `the following portions.` At either side of the wringer at 19 and 20 are shown flat 65 metal pieces, slidable within the ends 10 and 11rand projecting substanti ally to the lower end of the base plate 12.

This second set of \end plates -has pivotal engagement as at 21 and 22 withA a transversely extending handle or quick release member 23.

So far we have described merely an aux-y iliary frame portion slidable wit-hin the mainframe portion. The end plate 20 of said auxiliary frame portion has no operative relation particularly with the projecting ends of the wringer rolls, however, the opposite plate 19 has an extended slot 24, permitting the projection of the drive connection v18 therethrough. l

. VAdj acent the lower ends of both

end plates

19 and 20 are formed

transverse slots

25 and 26. These slots openinto the

larger apertures

27 and 28 formed inthe end portions 10 and 1.1 of the main frame. The only con-l nection between-the main frame portion and theauxiliary framelies in a transverselyextending at spring 29, housed within the anl gularly shaped hase 12, said spring having its projecting ends ,projecting through the

slots

25 and 26 of the auxiliary frame; as

well -as through .the

apertures

27 and 28 of .themain frame.

side inthe lower ends of the end portions `10 and 11, the

screw members

31 and 32 which are adapted to regulate the positloning of the auxiliary frame and flat spring 29 with relation to the main frame portion.

A removable upper wringer roll 33 has its projecting ends mounted inthe wooden bearings 34. Due to the frictional engagementioned bearlngs' 34 are not permitted to have engagement with the upper ends. of the bearings 16. This frictionalmountln'g of the upper and lower rolls is a conve11`t1ona1 1j structure.

Metal strips 35 overlie the rounded. upper exox portions of the bearings 34 and provide guide ways for the small roller member 36 on the release arm 23. IThe rollers 36 are mounted in the quick release arm in the following manner:

Bearings 37 have one of their ends engaging the outer side of the quick release arm and their opposite ends supported in brackets 38 positively connected to the arm 23 as at 39.

The operation of my device is as follows: normally the quick release handle 23 lies directlyiover and in the same plane as the wringer rolls, and when in this operative4 position through the rollers 36 applying pressure to the bearings 34 force the upper roll 33 toward the power roll 17. Pressure between the rolls is produced because. of the fact that the auxiliary frame portion, of which the quick release handle is a part, has a tensioned relation to the main frame, this due to the'mounting of the transverse spring 29. In other words, it is the peculiar mount-^ ing of the transverse spring in the base 12 and its-engagement with the projectingends of the auxiliary frame member` that produces the vtensioned mounting of tle roll members.

In Figure 2 the various positions of the release handle are shown, and it is clearly seen in said `figure that the handle 23 may be thrown to either sideof the wringer, to release the tension onthe upper roll, the actual release being of the flat tension spring 29, the ends ofwhich drop down due to the lowering of the auxiliary frame.

rlhe setting of the upper roll is accomplished by merely forcing the release handle again to itspositon above the roll, this being possible due to the cam-like action of the rollers 36 on the rounded portions 34.

`What l' claim is:

l. in a device of theclass described, a main ramehaving a power roll mounted therein, an auxiliary frame slidably mounted on said main frame, a transversely extendingflat spring mounted on said main frame andhaving its ends connected withy the `auxiliary frame, an upper wringer roll having bearings mounted in said main frame and a quick release arm pivotally connected -with the auxiliary frame on an axis parallel with the axes of the rolls having means engaglngthe sbearings of the upper roll and maintain sald roll in pressure relation to the lower roll, said arm being swingable on its axis to engage and disengage said means and bearings.

'2. In a.. device of the class dcribed, a'

mounted in said frame and connecte-d at opposite ends to the auxiliary frame, means connected to the upper roll normally engaged by the bail member for holding the rolls in pressure relation through thetensioning of the spring, said bail member being swingableon its pivot to release the tension of the spring and thereby the pressur between therrolls.

3. In a device of the class described, a vmain frame having a power roll therein, an upper wrnger roll overlying said power roll, bearings in which said upper wringer rollis mounted and having rounded upper end surfaces, lan auxiliary trame4 slidable within the main frame, a transversely extending fiat spring located 'in the base portion of the.

main frame, and engaging at its outer ends the auxiliary frame, and a swingable quick release member pivotally mounted upon the auxiliary frame and having seating members thereon adapted to engageand seat 1n connection with the rounded bearings of the upper wringer roll in a manner to normally hold said rolls pressed together.

4. ln a. device of the class described, in combination, 'a main frame, a roller therein, a bar spring supported in the frame below the roller, a second roller member, supporting` members therefor movably and removably supported relatively to the main frame, side bars slidable on the main frame and connected vwith the ends of the spring, and a bail member pivoted to the side bars on an axis parallel With the axes of the rolls and swingable into and out of engagement with the supports for the upper roll.

5. ln a wringer, a main frame, a roll and a bar spring supported in the trame, a see- .ond roll having bearings movably positioned in the frame, releasable interlocking yinea-ns for said spring and rolls including slidable bar members connected with the opposite ends of the spring, and a swingable member pivoted to the bar members in the plane of the axes of the rolls and engageablc with the movable `bearings to etl'ect said interlocking and apply force to the movable roll.

. In testimony whereofI aiix my signature.
