WM. M. DOTY, E P. DOTY, AND ELLIS DOTY, OF JANESVILLE, WISCONSIN.

IMPROVEM ENT IN WASHING-MACHINES.

Specification forming part of Letters Patent N0. 56,910, dated August 7, 1866.

To all lwhom it may concern:

Beit known that we, WILLIAM M. DOTY, E. P. Do'rY, and ELLIS Do'rY, of Janesville, in the county pi' Rock and State of Wisconsin, have invented a new and Improved Washing-Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying Y drawings, forming part of this specification,

in which- Figure 1 represents a transverse vertical section of this invention, the line a: ac, Fig. 2, indicating the plane of section. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate like parts.

This invention relates to certain improvements in that classof Washing-machines on which Letters Patent have been granted to us January 30, 1866.

Our present improvements consist, first, in

.the use of a spring on each of the fulcrumpins of the oscillating` Wash-board, with its ends extending from said fulcrurn-pins in opposite directions, one to bear on the edge of the tub and the other under a pin projecting from the lo aoket which forms the bearing for the appropriatefulcrum-pins, in such a manner that in depressing the handle each spring is -Wound up and the pressure on each fulcrum-pin is balanced, one end of the spring pressing up and the other down, and said pins are prevented from wearing out.

It consists, further, in combining with the Wash-board flanged segmental cheek-pieces,

` which are grooved to receive the handle, and

so formed that they prevent the water from splashing out over the ends of the tub.

It consists, finally, in the arrangement of cleats on the ends of the tub, in combination with the upper ends of the' legs, which are -secured to the tub, each by screws or bolts, in

such a manner that the end pieces of the tub are free to expand and to contract without being liable to crack, and at the same timeV the legs are firmly held in position.

' A represents a tub, made square or oblong, or in any other suitable form or shape, and

provided with brackets a, which rise fromV the edge of the tub, and the other, d, to catch under astop, e, which projects from the bracket a. By this arrangement the springs are wound up simultaneously from both ends, and the full power thereof is brought into use when the handle is set in motion, and at the same time the lateral strain exerted onV the fulcrum-pin by one end of the spring is counteracted by that exerted by the other end,

and the pins are prevented from wearing out.

By making the stops c adjustable the strain of the springs can be increased or decreased at pleasure.

The cheek-pieces U are made Wide and caused to project a suicient distance above the wash-board, and their ends are chamfered oft', so that the water is prevented from splashing when the wash-board is set in motion. These cheek-pieces are grooved to receive the handle D, and this handle D is so arranged that it can be readily taken out and that the whole machine can be packed up in a comparatively` small compass.

The tub is supported by four legs, E, Which are fastened toits ends by screws or bolts, and the upper ends of said legs catch in suitable sockets in cleats F, which are secured to the ends of the tub, as shown. By this arrangement the legs are enabled to accommodate themselves to the expansion and contraction of the end pieces, and they are firmly held in position Without causing said end pieces to crack, which they are liable to do if the legs are fastened to both their lower and upper edges.

We disclaim everything included in our former patent of January 30, 1866i.

What we claim as new, and desire to secure by Letters Patent, is-

l. The combination of the spiral springs c d fulcrum-pins b, and oscillating Wash-board B, constructed as described, and operating substantially as and for the purpose specied.

2. In combination With the above, the projecting cheek-pieces C, With chamfered edges, constructed and operating` substantially as an d for Jche purpose described.

3. The cleats F, fastened to the ends of the tub, and provided with sockets to receive the upper ends of the legs E, which are fastened to the lower edges ofthe ends of The tub with screws orbolts, substantially as sind for Lhe purpose set forth.
