WRINGER v Specification of Letters Patent.

Patented July 8, 1919.

Application led March 3, 1917. Serial No. 152,414.

T all 'iw-hom lima-y concern.' L

-l3e1t knownthat I, HERMANROEMER, a citizen `of the United States, residing at the citybf Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inlli'ingers, of

which the following is a specification.

My invention relates to wringers which are used for removing the superfluous water from, clothing and other materials. Then such devices are power driven and lage quantities of material are being passed rapidly therethrough they are liable to cause vserious inJury to the operator it any portion of the person or clothing is accidentally caught inthe rolls. It is the object of my invention to provide means applicable, with slight changes or modifications, to such ma- .r chinery as is commonly 1n use by which, in

case of accident, imminent or actual, the free roll may be. unse-ated and freed from its operative relation with the driving roll.

The principles of my invention are illustrated in the drawings, in which- Figuie 1 is an elevation of a' wringer equipped with my in'iprovement;

Fig. 2 is an enlarged top view thereof; Fig. 3 is a similar view partly in section of the upper part of such device showing my improvement; y

Fig. 4 is an enlarged vertical section` of v the roller bearings and gea-ring of a typical wringer.

Further describing my invention with referenceto the drawlngs: l, 1 are the vertlcal standards of such machlne. 2- 1s a lower cross bar and fabric guide. 3 is a driving shaft, journaled in bearing `blocks 3', and 4 is the principal roller on such shaft. 5 is a roller mounted on shaft 6, journaled in bearing blocks 7. Said bearing blocks are slldable in the bearingguides 8, and shaft G is Aprovided with. gears 9 meshing with gears V10 on the main shaft 3.

housings.

11, 11 are gear An arched evener 12 spans the space between thebearing blocks and the ends thereofgrestl'on theslidable members,

- which playin the `bearing guides. A bowspring 15 is placed above the evener and a cross bar -16 bears centrally on the upwardly bowed portion of said spring.

The structures thus described are held 1n place by the upper cross bar or abutment piece 18, which is secured to the upper part of the standards .1, and `lthrough which pass the spacing screws 19,' which bear in the Aends of cross barlG, and by which the pressure of the rolls is regulated. The upper part of the frame is provided with a metallic framework which mayv consist of the clips 20 secured to the upper ends of the standards l, and connected by the trans A plurality of sliding guiding strips 30. It is also providedwith slots 31 and 32, the uses of which will be hereafter explained. l Bolt 25 has an arched portion 33. It is further provided with a tail piece 34 slid- `able in slot 31 of boltl 24 and under the guide 30. The outer-portion is held in position bythe guide 35, and it is further pro- -vided in the arched part thereof with opening 36. A plurality of plates 37 is secured `to the abutment piece 18, and between them on the pivot 40 is mounted a leve r: 41, which passes through slot 36 in bolt 25 and 'slot 32' in bolt 24 so that the bearings thereo in the two slots are substantially at equal 'distances from the pivot 40. A spring p42 connects the lever 41 to a stationary lug 43, whereby the lever is normally held in the position shown in Fig. 1, so that the two bolts will be equally extended, and sol that the extremities thereof will pass into the openings in the striker plates 27 and be engaged therewith. When the wringer is in use the relative parts will be in substantially the relation shown in Figs. 1 and 2, the upper roller 5 being in contact with roller 4 under pressure of the bow spring 15, as established by the spacing screws 19.- Said spring moreover acts to balance the pressure at the ends of 100 the rolls, thereby avoiding the necessity of operative to exert any material pressure on anythln which may have accidentally been drawn t ere'between.- The device may again by pressing be placed in operative condition the handle to the lowest point, putting the abutment piece in its normal ositon, land releasing the lever, whereby t e spring 42 will cause the bolts to lengage the striker plates and cause 'said piece to be lockedin normal position.

In a Wringer'; a frame, a plurality of rolls journaled therein, anabutment piece above the said rolls, a spring device interposed'between the abutment piece and the ,rolls to hold the latter normally in coperative4A rel.pluralityof plates on the sides of the abut- .bolt and provided "with a slot, said second bolt bein `slidable on the abutment piece to engage t e other 'of said striker plates, a

ment piece, and a lever pivoted between said plates to' engage withmthe slots of said bolts. A In witness whereof, I havehereunto subscribed my name this 28th day of February,

1917, at Chicago, Cook county, Illinois.
