To ALL .WHOM IT MAY coNcERN:

Be it known that we, H. J. CASE and F. I. JOHNSON, of Sugar Grove, inthe county of Warren, and State of 4 Pennsylvania., have invented certain new and useful 'Improvements in Vv'ashing-Machine; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompany-A ing drawings, making,part of this specification, and to the letters of reference marke-d thereon, like letters indicating like parts wherever they occur. i i I To enableothers skilled in the art to construct and use our invent-ion, we will proceed to describe it.

Our invention relates to washing-machines, and consists in the novel arrangement of two peculiarly-grooved rollers over one that is stationary, in such a way that they may operate and adjust themselves to the article or articles being washed, independently of cach other.

AIn the drawing- Figure l is a longitudinal vertical sectional view of our machine.

In constructing o ur machine, we make an oblong rectangular box, A, of any desired size, and mount in supports z', placed on each side of the box A, and fastened toit, a large grooved roller, B, as shown in the figure. The crown of the supports we make circular, and so as to be on a line with the outer ends of the teeth ofthe roller B, as shown, in dotted lines. In the corners of the box A, we place braces Gand H, both to strengthen the box, and as supports for the arms E and F, which are hinged to them at a and Z1, and which extend` to the middle of the box, and have pivoted between their outer ends the rollers C and D, grooved, so as to correspond with the grooves in the large roller B. The arms E and F, when in position, are arranged so thattheir upper sides shall be lush with the upper edge ofthe box A, except at their outer ends, which incline upward, as shown in the drawing. The extreme outer ends of these arms E and F, we connect with cross-pieces c and d. As the roller C is pivoted-or mounted between the out'er ends of the arms E, which are hinged-in the braces` G, and as the roller D is similarly arranged between the arms F,- they t-husmove independently of each other. The roller C may be raised by the crosspiece c, and thrown back, as shown in dotted lines in the drawing, vand the roller D may continue to operate, and it, too, may be raised and thrown up. The rollers C andD are smaller than the roller B, asshown in the drawing. Their grooves, howevenfare made to correspond with those inthe roller B, and with each other, and are of a novel form, their base, It, being dat, lor nearly so, their sidesg, also flat, and at right angles with the length of the rollers, and their extreme outer lines rounding. We have found that grooves made in this form do not injure the clothes or articles that pass between them, especially when tliereureA hooks or buttons upon them.. I- l The braces or supports H we extend above the upper side of the box A, and mount therein rubber rolls I and J, or rolls covered with rubber or any substance suitable for ringers. The `journals of the upper roller I turn in bearings arranged to move vertically in slots in the supportsH. These bearings are heldin place and made adjustable automatically by a metal springe, or any' other suitable device. Across the upper ends of' the supports or standards H we attach a cross-bar,f, to strengthen them, 'as well as to prevent their spreading.

To vthe roller B we attach a crank, which is upon the outside of the box A, and to the roller J we also attach a crank, which is on the outside of the brace, support, and standard H.

In operating our machine, we ll the box A with water to' the desired height, putthc clothes'or other articles Ato be washed into it, and draw them backward and forward through or between the rollers-B,'C, and 1),. by giving the roller B a.' rapid reciprocating motion, and thus thoroughly washing the articles. l

As the rollers C and D are pivoted in separate arms, E and F, each, will move'and adjust itself to the Asubstance vinterposed'between it and the roller B, independent ofthe other, and for this reason will operate more elfectually and with greater' advantage than they can do when attached tothe same arms hingedat one end of thebox. I i.

The cross-bars c anu a, connecting the outer ends ofthe arms E and F, supportand strengthen and secure steadiness in the motion of the small rollers C and'D between them;y and, when-it is desired, theoperator can press` with hishand upon the bars @and d, and thus cause the rollers tc'rub upon, the interposed substance as d as n'my he necessary to secure thorough washing, or, it' he wishes, o weight may be placed upon them for sume purpose. y

The clothes, when washed, we poss between the Wringingmlls I and J, which completes the operation. We have found, byfact'ual experiment, that a washing-machine constructed in this way is very elfectuol in operation, washing the lightest as well the heaviest articles rapidly, thoroughly, und without -the usuul uiy to the fabricoausedby many other machines. t

Having thus described our invention, what we claim, s Au improved washing-machine., consisting of a. box, A, having mounted therein the grooved roller B, in cotu- .ation with the grooved rollers C and D, mounted respectively in the' :i1-ms E und F, hingedindependently oi' :h other, and provided with the cross-borse aud cl, all constructed and arranged to operate substantially as rein described.
