Letters Patent No. 99,842, dated February l5, 1870.

IMPROVLED WASHING-MACHINE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may 'concern tub, of which (l (l are the ends, and e the bottom.

ln it is placed the wash-board a. a a?. This board is so curved as to constitute a segment of a circle, of which the center is at o in the frame above. This board is divided into three sections by the hinged joints at t t. Of these sections, the. middle one, al, is secured firmly in its place by being framed or otherwise fastened to the sides of the tub.

rlhe end sections rest freely against the ends of thc tub, andare left free'to more upon their hinges, as the naohine is opera-ted.

'lhe wash-board maybe made of tinted stuti, or of' rollt rs suitably framed, or of both combined.

On each side of the oblougbm or tub, equidistant from the ends, are fastened upright posts or strips l.

Holes in the upper ends ot' these pieces are made to receive the ends ofthe cross-piece p. These ends are round, so as to revolve'iieely in the holes'at o.

Through the `cross-} iece other holes are made to receive the ends ol' the perpendicular pieces h, to which are suspended the rubber f. This rubber is a box, of which g g are the ends, and b'the bottom. The latter is convex, to correspond with the concavity oi' the nnshdioanl, and may be made as is the wash-board, either ci' tinted stnli' or of rollers, suitably framed together.

Swinging upon the center of motion at o, the rubber is carried backward and forward over the curved surface` ofthe wash-board bythe power applied to the lever t' i. The fulcrum ot' this lever is a screw, v, in the frame-piece of the rubber, whilst its end is held bythe screw :t in the oscillating rod o1 bar, which swings ou its center.

To the ends ofthe uprights h, above the cross-piece p coiled' springs m are attached, by means of which the leverage bearing upon the clothes is diminished with the more facility by the operator, and when the hand is removed from the lever at j, the rubber is lifted from the clothes.

To the ends of the hinged sections ofthe washboard chains q r are att-ached, which hook to the upper edge ofthe ends of the rubber box.

When the machine is to be operated, one chain is detached, and the rubber is lifted out of its bed by the spiral springs. The waterand soap arel put in the tub, and the clothes distributed upon the Wash-board. The rubber is then brought down by pressure on the lever, and the chain fastened to'it-s place. A reci procating motion backward and forward is then given to the rubber by the hand applied to the handle j ofthe lever. This movement is attended by a downward pressure ot' 4the lever, which is more orrless powerful as the clothes may require severe or gentle treatment.

As the rubber is pushed from the operatortoward the. farther extremity of thetub, the chain Jr lifts the ibrward section a ot' the wash-board, which, turning on its hinges, tilts the clothes over, and throws them under the retreating end ot the rubber. When the movei'nent is reversed, the section fr is thrown back to its place, the clothes are carried forward between it and the rubber, and, at the saine time, the section a* is lifted by its chain q, and the. clothes which were upon it tilted over and thrown under that cud of the rubber. .ihe operation is repeated until tile clothes are cleansed, when the chain 1' is detached, the rubber rise-s, and the clothes are removed.

What I claim as my invention', aud desire to secure by Letters Patent, is-

The combination with the. box C of the hinged wash-boards a a2 and central boards a, chains q e', rubber `box b f, bars h, sock-shaft p, springs my, and standards Z, the rubber being operated by means of the levers t', all constructed substantially as specified.
