IMPROVEMENT INMAcHiN'Es'FoR'wAsl-HNG AND WRINGING cLoTHEs. 4

The Schedule referred to h1 these Letters Patent and making peut ci the same.

To all whom 'it may concern.:

Be it known that I, ANDREW CLARK, of llymouth, in the county of Richland and State of Ohio, have invented a useful and Improved Washing and Vringing-Machine; aud I hereby declare the following to be a full, clear, and exact description thereof. sufficient to enable those skilled in the art to which my invention appertains to fully understand and to make and use the same, reference being had to the accompanying drawing forming part of thi; specification, and in which- Figure 1 is a ltop Iview; v

Figure 2, a longitudinal section, taken on the line a' x, tig. l;

Figure 3 is a detached view of .a spira-lly-groovcd roller; and Figure ,4 isnJ transverse section, on the line y y,

4Similar letters of reference indicate like parts in the several figures.

.My invention consists in a novel formation of the grooves in the main roller; inthe construction and arrangement of the springs, which exert pressure on the grooved roller; in the provision of a washing and wringing-machine, with' springs so made and applied as to serve for bot-h the washing and \vringing-rollers; and in the general crmstruction, arrangement, and combination of parts, all as hereinafter fully set forth.

Referring to the drawing- Arepresents a box or tub, preferably ol' rectangular form, and .with a. 'rounded bottom; and provided withsupports a lt.

In the inner faces of the sides l) l) aremadc vertical grooves c c' c.

(l cl d represent a scrics'of small plain rollers, ar

ranged in a scmicircle, and journaled at their ends in pieces c e, held together by side strips f f, the ends of which tit inthe grooves c c. Under the strips f are spaces, which p cr'mit thc free passage and circulation of water. B represents the main roller, one journal of which rests in the groove c', while the other passes through a vert-ical slot in the opposite side ot" the machine, and is provided with a crank-handle.'

The surface of .the roller Il is grooved, as shown in iig. l., or asin iig. 3, the grooves in the one case being angular, and in the other spira-l.

It is designed to provide the entire surface of the roller with the grooves a', and it is not important whether the grooves are spiral or angular, as both have substantially the same effect, which is, however, different from the effectwhich would be produced by grooves parallel with the axis of' lthe roller.

The object in making the grooves of the fcrinsdescribed is to cause the intervening ribs 'i 't to work tightly on the rollers d, and at the Sametime smoothcorners arc not rounded, and thus their ei'iiciency is improved.

' lhe main roller is kept in contact with the concave of small rollers by the pressure of springs g, which, 4at their centers, bear on the journals of the roller B, the ends of the springs being sprung under lugs h at'- ixed tothe box A at its corners, inside.

Each spring y consists simply of a long strip of tough elasticwood, protected by a metallic boxing s at the point where the spring comes in contact with 'the journals of thc main roller.

Having described the machine as it will be made simply for washing, I will now proceed to explain the construction of the wriuger.

j j represent`l standards attached rigidly to one end ol the-box or tub A, on its inncr surface.

7c is across-piece connecting the standards.

The upper roller I is .jnurnalcd in stationary bearings in the standards, but the lower roller m has its bearings in movable blocks iitted in vertical slots in the standards.

The lower roll is kept in contact with the upper by means of a two-part spring, n o, which has its bear ings on the springs l/ g of the washingmachine, as'

.the insertion of l'ulcrum-blocks 7) under the springs,

a short distance from their ends.

The rollers ot' the wringcr are preferably made of or covered with rubber, and they may be geared together it' desired.

q is the crank-halnlle of the wringer.

Ihe washer and wringer may be operated either separately, by the szunc attendant, or in concert hy two 1wrsous,thc clothes being either conducted di rcctly from the washer to tlie wringcr as fast as they are cleansed, or allowed to accinnulate in the tub.

The washing mechanism and springs can be all readily removed for cleaning purposes,and in replacing them the roller-frame and springs can be inserted without regard. to their former position.

This feature, in connection with the ext-reino sinid plicity,V the durability and obvious utility of my machine, renders 'it a. valuable improvement.4

It` will be seen that although the wringeris, on account of its construction, dependent upon the washing-machinc, the latter is complete in itself, and, therefore,I wishit understood that I do not limit myself to the washer when provided with the wringer. I do not claim the combination of a wrnger Wit-h a, washing-machine, as this is old; but

Having thusdescribed my invention,

What I claim as new, and desire tosecure by Let-ters Patent, is-rer 1.' The combination and arrangement of the square,

grooved roller B, concave of rollers d end frame e f, the springs g, blocks h, and tub A,' all constructed and operating as described.v y l v 2. A'lhe-slnings g g, grooved roller.` B, concave of rollers 11, frame e f, the tub A provided with blocks h l1, and lulcrums p 11, and lwringing mechanism composed of the parts j j h, rolls l an, loose bars n o, and crank q, all constructed and arranged to .oper--l ate substantially as herein set forth.
