Letters Patent No. 108,689, dated October 25, 1870.

IMPROVEMENT IN WASHING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Bc it known that I, EzRA D, Av1sof Keoknk, Iowa, have made a new and useful Improvement in Washing-Machines, which I declare to be made and used substantially as shown and sctforth herein and inthe accompanying drawing, in which'- Figure 1 is an end elevation of my improved wasning-machine. A

Letters of reference are used correspondingly throughout.

My invention consists in arrangement of' parts and devices in a machine i'orwashingior domestic purposes.

A is the box'for containing the snds-and clothing in washing.

Bis a cylinder turning in box A, and having its center-shaft C resting in bearings in the ends oi' the box A.

D is a lcrank-arm from one end of C outside of the box A', for turning the cylinder by-lneans ot a ptman, E, to the foot-treadle F.

To Fis .pivoted a pitman, G, which reaches up tothe hand-lever, H, for operating by hand,- w,hen preferred to the foot.

` Iart I is pivoted at the bottom of the box at I' in# lside, one board at each end of the box.

Between these two boards is a connecting part, forming a top to the concave K, in which the cylinder B turns. This part K can either be formed of a solid surface or of slats.

The clothes are placed to wash between the wheel and this concave, so that the turning of the cylinder will operate on the clothes.

L is a y-wheel on the end of shaft C, to give regular motion to the parts.

- Between the two parts of I is a handhold,M, to raise or lower part I and concave K by, to put-in or take out clothes,'or examine the washing, &c., or to A[wessdown upon the clothing in the washing.

lhe cylinder B is surrounded bya series of rollers, N N N, which are free to revolve under the clothing during the turning of wheel B, and subject it to a continuons passage of rollers, by which it is caused to be washed. These rollers' areturued, and are formed with alternate ribs and hollowsV around them, so arranged thatythe large part of oneis opposite the small 'part of another.

The action of washing is done out of the water, and

between the rollers N N and N and the concave K.' So that the washing can be readily seen, regulated, and

continued in each 'instance just till it is fully completed, and not over long, nor too short; and so that the mass of water will not carry ofi' the soap too freely from the work.

What I claim isrlhe combination andarrangement of each of these parts to form-a washing-machine, to wit: The footlcver F, the pitman-bar G, the hand-lever H, the pit- Aman E, cylinder B, box A, ily-wheel O, peculiarlyformed rollers N N N, part I, and concave K, all substnntially as shown and set folth.

EZRA DAVIS.
