WILLIAM R. RICHARDSON OF SAN FRANCISCO, CALIFORNIA.

IMPROVED WASHING-MACHINE.

Specification forming part of Letters Patent N0. 38,061 dated March 31, 1863.

T0 all whom it may concer-n.'

Be it known that I, WILLIAM R. RICHARD- SON, of the city and county of San Francisco, and in the State of California, have invented a new and useful Machine for Washing Purposes; and I do hereby declare that the following is a full, clear, and exact description of its construction and operation, reference being had to the accompanying drawings and the letters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a sectional or side' vie w. Fig.'2 shows a top view. Fig. 3 illustrates the circular fluted roller, together with the concave roller-frame placed over said uted loller.

The nature of my invention consists in furnishing an apparatus that will e'ectually wash and cleanse clothes of every description, be they of the nest fabric or of the coarsest material.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct the trough or tub A so that the two longest sides shall be parallel to each other, and the ends may be tapering or run down an incline, as represented in Fig. l, allowing the saine to rest upon four or more legs.

B represents a luted cylinder or roller, through the center of which shaft C is permanently secured, and said shaft is provided with a crank, D, for revolving the same. The ends or projections from said shaft run in journals in the sides of said trough A. On one side of cylinder B, I secure a cast-iron eccentric die, E, which has an aperture near the outer edge for allowing 'the shaft C to pass through, and when revolving imparts a back and forward motion to the plunger or sliding frame F, which is placed between the cylinder B and the trough A. In said plunger F, I allow a square or an elliptical opening, G, for the eccentric die E to play therein.

El is an upright piece with perforatons through the whole surface, and is fastened on each side to the projecting arms I of the plunger F. Said arms run between the guides and upright and stationary piece J, which is similarly perforated, and said perforation in H and J are for the purpose of allowing the water or air that maybe pressed from the articles to be washed back into the trough A when the plunger recedes, or will force such water or air into the chamber K, which is also perforated.) The motion of said plunger is alway horizontal, requiring comparatively little power to work the same.

Immediately over the luted cylinder B is placed the concave roller-frame L, which frame is secured by hinges to the top edges of the trough A, and contains a number of rollers, forming a concave surface concentrically with cylinder B at abouta sixteenth of an inch play between said cylinder and rollers. Said roller-frame L is placed thus for the purpose of insuring the necessary friction required in washing fabrics of the finest textures. One hand may be employed to revolve the crank, while the other hand may hold said roller either loosely or firmly down, according to the articles to be operated upon.

The economy of time and labor have been the aim of the inventor.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the eccentric die E with the cylinder B, the plunger F, sliding in guide J and revolving in opening G, and the roller-frame L, all arranged substantially as and for the purpose set forth.

W. R. RICHARDSON.
