WRINGER.

Application iled July 29, 1921. lSerial No.` 488,386.

fo all whom t may concern:

'Be it known that I, WILLIAM citizen kof the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in- VVringers, of

V. ORR, a

`which the following is a full, clear, and

exact description, reference being had to the accompanying drawings.

This invention relates to clothes wringers, especially to those designed for power 0perati'on as in electrically-driven, domestlc washing machines, although not limited to such use. The main objects of the invention are the provision` of a device of this character which shall wear better and run easier than previous machines; which possess a particularly flexible spring-action; which shall be constructed all of metal and of great rigidity; which shall be all tight and clean yand wherein all operating parts are closely housed; which shall possessa new and improved tension-release or emergency catch; which shall be constructed of simple parts easily manufactured; while further objects and advantages will become apparent as the description proceeds.

1n the drawings accompanying and forming a part of this application I have shown an illustrative embodiment of my invention, although it will be understoodthat many changes can be made within the scope. of my inventive idea. F ig.1 represents .a side elevation of a wringer embodying my improvements; Fig. 2 is a vic-w similar to Fig. 1 but with the front plate of the wringer removed; Figs. 3 and 4 are sectional views corresponding to the lines 3 3 and 4 4, respectively, of Fig. l and looking 'in the direction of the arrows; Fig. 5 is an enlarged detail viewy showing the result of releasing the emergency catch; and Fig. 6

is a detail sectional view upon the line 6-6 of Fig. 5. i

The frame of my improved wringer is preferably made of two reversely-symmetrical, cast-metal members .which are approXimately rectangular in outline.- Flach comrises a pair of upright risers, a 4straight bottonrbar and a top bar which may be straight but is preferably arched both for strength and for appearance. Each top bar has a depending web 1 spaced from the other web* and a top flange 2 which` meets the other top flange closely except for the 'catch andthe notches 4 which are le notches 3 which are left for the emer ercy t` or the adjusting screws. Each riser comprises a hollow semicylindrical bod 5 spaced from and facing the opposite bo y, their opposing edges 6--6 constituting vertical guide- Ways. Each riser of one pair is formed with a flange 7 projecting toward the opposite flange and making a tight joint; each riser of the other pair is formed with a.' hollow extension 8 which cooperates with the mating extension to form a gear box whose Amouth is Hanged as at 9 for attachment to the. supporting bracket 10. The bottom of each riser is formed with a web A11 and that of the extension with a web 12 adapted to make an oil tight joint with the web of the mating member. The bottom bars 13-13 are spacedapart suiiciently to receive the llower roll and are shaped to constitute guides thereto. I'lhe ends of the frame are provided with notched ears 14-*14 which receive between them Ythe rod 15 that carries the drain board and the twol halves of the casing are held ,together by suitable screws 16e-16.

Slidably mounted in the guideways 6-6 are the bearing blocks 17-17 which are preferably rectangular pieces of hard wood.l

impregnated with lubricant,'and journaled in these bearings are the ` roll shafts 18 and 19 having thereon the roll portions 2O and 21 respectively. The sides of the bearing blocks are formed withv shallow notches which yreceive the legs 22 of' a U shaped saddle which rests'on the upper block, and slidably embraces the lower block, terminating in outturned feet 23. Each foot is formed with an upright study 25 receiving the lower end of a spring 26, whose upper end receives the stud 27 ofa yoke 28.

Suitably pivoted at each end of the frame, as about a sleeve 3U surrounding one of the bolts 16, is a nut 31 having at one side the shoulder 32 adapted to be engaged by the reciprocable latch 33, the opposite end of7 which is connected to the plvoted lever 34 pivoted between the webs 1-1 and projecting through the notch 3.. This lever and its latches are ordinarily held in engaging position by the spring 35, the latches being guided by integral studs 36 cast in the frame. rll`he nuts 31 are provided with adjusting screws 3737Y constituting tension members which, when the vnuts are so seico cured, press upon the yoles 28, but which upon the depression of the lever 34 ily to the position shown 1in Fig. 5, freeing the rolls completely,

lhe bearings of the lower roll rest on Ythe .bottom webs 11 and the 'box 8 isekpreferably "provided with a third bearing in line therewith and mounted on a seat il. rlthe usual roll gears, l2- 42 are located between this bearing and the adjacent bearing 17, and the lower roll shaft 18 is extended upon the opposite side ot this bearing sutticiently to receive a third gear 43 ada ted to mesh with a driving gear 44 mounte on the drive shaft 45 carried by the bracket 10. These gears are preferably `of the double-tooth,

cast-iron type generally used in wringers,v

and because they will run together at widely varying angles and distances they constitute a kind Hot flexible joint which co1npen,

sates for a very large amount of wear of the bearings which support the lower roll. This gear-arrangement fulfills all the requirements ot a double universal joint and with the added advantage of saving .length and expense. lt also prevents end-play of L' are provided with notches 54 adapted to receive the latch 55 carried by the wringerl risanare trame 'whereby the drain board is fixed in its adjusted position; and the latter are formed with projections 56 constituting stops to limit the movement ,of the drain board.

lt will be understood that many 'changes in design, construction, and arrangement can be made and that l: do not limit myself 1n any wise except as speciiically recited in ytrame having a central vertical rectangular guide-way therein, tubular recesses in said trame adjacent to said guide-way, a lower bearing block in the bottom of said guideway, a wringer roll journaled in said bearing block, an upper wringer roll journaled infsaid guide-way, an upper journal bearingI in said guide-way for the upper roll, arms on the upper journal bearing and extending therefrom downwardly in said re.- cesses, coiled'springs within said recesses and resting on the downwardly extending arms, a cross-bar in the upper portion ot said central rectangular guide-way and extending into'said recesses over the upper ends of said springs, and a tension device comprising an adjusting screw engaging said cross-bar for the purpose ot compressing said springs.

lin testimony whereof, l hereunto aiiix my signature.
