T all whom it nwyvoneem:

Be it known that we, FREDERICK GEORGE Sommrrz and WILLIAM: H. HARMAN, citize'ns of the United States, and=residents o f Phila- 5 delphia, Pennsylvania; have invented C61- tain new and usefnl Improvments in Clothes Wringers, of which the following is a specificatio Our invention relates to clothes-wringers, more particularly those having frames made of met al, and one object of our invention is to prdvide a clothes-wringer with quickaciping release mechanism for tlxepressureapplying means for the squeeze-rolls'.

A further object of our invention is to provi de a clothes-wringer' having a frame made wholly of me tal with quick-acting relea.se mechanism 'for the pressure-applying means for the squeeze-r0lls, disp0sedadja- 29 cent one end of the upper squeeze roll; the

opposite end of said. roll being'automatically released in a manner hereinafter described.

A further object of our inventi'on is to provide such qu'ick-acting release mechanisn'1 adjacent the gearing for' the squeeze-rolls, and a still furtl1er object of our invention is to provide simple and efllci ent device for actuating the quick-release means and for ohis purpose we prefembly employ a knock-ofi 39 device connected to one of the tension bolts formi part of the mechanism,which retains t e squeez8-rolls in place and appliea the desired pressure thereto; These and other fea.tures of our invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a frontgelevaliion of one form of clothes-wringer to which our improve'd quick-release device may be applied.

Fig. 2, is an end elevation look'mg in the direction of the arrow, Fig. 1.

. Fig. 3, is a diagrammatic view illustrating the osition of' the squeeze rolls after the operation of the quick-release device for the pressure-applying means therefor, und. Fig. 4 is a fragmentary view illustrating certain details o-f construction, in section on the line IVIV Fig. 1. 1 The wringer frame 150 which the features constituting our presen't inven n have been 'applied may be of' metal, bstantially U- shape in contour, and maycomprise upright 9nd portimis with g lgw9! COI1necting cross pne 0x a plunality of sections.

mgs we have illstrated a wringer 'frama .made of a plurality of sections, 1 und 2, fitbar therefor; such fmmle bei formell in n the drawting togqther 01'1 a median o r substantia-lly med1an l 1ne, as clear illustrated in Fig'. 2;

und secured t0gether y suitable means, such for instance as rivets 3. While the use of our invention 'is not limited theretoit is .shown in connectio n With a Wringer frame of thetype illstrateel and described in the pending applicat ion f F. G. Schranz, filed February 19, 1921, Serial N0. 446,226. The sections 1 and 2 0f the frame am vided with upright end portions 1* an 1", and 2 and 2", und these end portions may be Provided with inwardly disposed flanges or ribs 4, providing channels adapted to receive bearin blocks 5, fo r the spindles 6, of

squeeze rol s 7 und said bearing blocks.

may havia side ribs fitting the channels provided by the inner flanges ofsaid end. portions. These bearings am -preferably cf hard wood, and may be cut from a pre-. viously formdd blank in the manner describe'd in the applicatio1h of F. G. Schranz, filed Sept. 24, 1920, Serial Nurnber 412,449. The bearing blocks 5 are applied to the upper side ofthe spind-le of the pper roll and to the lower side of the spindle of the low.er roll, and the lower bearing blocks may be supported by inwardly disposed lateral pro jeclsions carried by the upr1ght end portwns of the frame.

At one side of tlie wringerframe a housin .9 is Provided, which may be integral w;th the upright end portion of the frame, and this housmg receives the gears 10 and 11 carried by the spind-les 6 of the sque9ze rqlls 7 Wheh the frame is 1 ixade in a plurality 0f sections, such housing may v be formed one half on each upright encl p1"- tion 1" and 2" of the sections making up the frame.

Hinged at12 to the upright end portions 1. and l", of the section 1, are=cap members 13 und 14, Which overlie the top of these end drawmgs; and these cap m@mbars carry at their opposite enrls bolts 15 und 16,-hung ortions, as clearly illusttated in tlm from pivot ins 15, and-16, mounbed in pairs of ears 13 und 14 of the res ctive cap members; said bolts being adapte to undenupright end portions 2 and 2 of the secti on 2. The bolts 15 and 16 carry springs 19 mterposed between washers 20 and.20 also carried by the bolts and which may be lying means for the squeeze-rolls 7 mcludes lugs or projections 22 disposed on the under sides 0f the cap'members 13 and 14, and preferably integral therewith; such lugs or'projections directly engaging Wear pieces 24, in ehe form of metal yokes, carried by the bearing blocks 5, for ehe spindle of the upper squeeze-roll.

In this arrangement of quiek-release mechanism for the squeeze-rolls, which mechanism is located at one side only of the wringer frame, the holt 16 is provided With an upwaxdly extending member 25, terminating in a band plate 26, which extends over the squeeze rolls. The member 25 may be integral with the holt 1601 rigidly secured thereto. Depression of the band p-laoe 26 or movement in t-he direction of the arrow w, will swing the bolt 16 on its pivot pin 16, and release its spring 19 from engagement with the pairs of lugs 18 ofthe upright end portion; thereby relieving the pressure applied by said spring at one end of the squeeze-rolls. T0 com'pletely release this pressure-applying device it is only necessary to depress the handle 25 to the position shown by dotted lines in Fig. 2, whereupon the spring holt 16 and the cap member 14 will be withdrawn from their operative engagement with the lugs 18. and the upper roll Will be completely freed from the pressure applied by the springe 19.

In this arrangement of quick-release device, only one end 0f t-he upper squeeze roll is relieved, -As the opposite end of said upper roll is unsupported, however, the bearing block therefor being disposed above the spindle to take th e upward thrust, said upper roll is free t0 drop .at its unsnpported end and may rise at the end normally umlerlying cap member 14, when the latter has been rernoved as above described and as clearly indicated in the diagrammatic view, Fig. 3, comnletely removing all danger of injury to the operator should a finger or other portion of the band be caught between the rolls; er to the wringer frame. should' the matarial passed between the roll s tend to pile up. Should the upper squeeze roll continue to turn after the p-ressure at one end of the Same ha.s been released in the manner indicated, it will draw away from the frame and be wholly free as indicated by its position in dotted lines, Fig. 3.

As in" the pending application Serial Number 412,449, before referred to, a drain board 30, also of metal may be arranged to lie below housings 31, formed on the 1nside of the upright end p0rt-ions of the frame for the outer ends 0f the squeeze rolls, andthis drain lioard may be 'adjustably held in place in the same manner as illustrated in said application. The usual guide plates 32 to d1rect the garments to the bite of the squeeze rolls may be employed. as in all similar structures; said guide plates having projections 33 Which engage the edges of the housin s 31.

ower to drive the squeeze rolls may be applied to either spindle but in the present case we have shown the lower spindle as projecting beyond the end of the frame, as i ndicated at 6?, for operative engagement with a driving element; the shaft of' a suitably aet-uated motor for instance. In lieu of this, the projecting spindle may be engaged by a suitable crank-handle, 01' o ther form of power-applying member..

As in the structure of the pending application Serial Nu1nber 446,226 before referred to, it will be readily understood that if both cap members- 13 and 14 are released from' their spring efigagernent with the frame and swung back an their hinged counection with the upright end portions there- 0f, the squeeze-rolls .7, with the bearingblocks 5, may be removed. This peirmits ready assembly and removal of the various parts 0f the structure, for renewing J;he bearings 01' squeeze-rolle; er other repairs, as occasion may require. There are n0 parts to geb out of order 'or readily break, and any suitable form of clamping device may be employed to att-aeh 0111 improved wringar to a. washing machine or tub, er at any other diasired point.

It will be understood that we do not wish t0 be limited to the' exact ronstruction disclosed in the drawings and deseri bed herein, and our claims are designed t0 cover any equivalent construction having the stune 0r a similar object in vieW. lt will also be understood that our improvements may be applied to wooden or metal frames, and that the latter may be made of cast er pressed metal, withbut departing from our invention.
