UNITED STATES PATENT OFFICE.
MELVIN M. TUCKER, OF CARSON CITY, MICHIGAN.
WASH-BOARD.
SPECIFICATION forming part of Letters Patent No. 223,458, dated January 13, 1880.
Application filed December 4, 187B.
To all whom it may concern:
Be it known that I, M. M. TUCKER, of Car son City, in the county of Montcalm and State of Michigan, have invented certain new and useful Improvements in Wash-Boards; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accorn pan yin gdrawings, which form a part of this specification.
Figure l is a front view of my improved wash-board. Fig. 2 is a vertical central sectional view of the same. Fig. 3 is a front view of the metal rubbing-plate.
This invention isdesigned to furnish a wash board with a metal rubbing-plate provided with a plurality of raised projections or bosses of a certain shape, as will be hereinafter more fully set forth, and pointed out in the claim.
In the annexed drawings, forming a part of this specification, the letter A represents the improved wash-board, which consists, essentially, of the side pieces, B B, having legs 0 C, and united by the back board, D. This back board, D, instead of being solid-one pieceas is usually the case, consists of two or more pieces, a a, with a space, I), (see Fig. 2,) between of one inch (more or less) to compensate for the swelling caused by the water, which often causes boards of a single piece to warp and crack, and also allows for the expansion and contraction of the metal rubbing or working plate attached thereto. The letter G indicates the zinc working-plate attached to the back board, D, in any of the well-known ways. This plate is provided with a number of cup or crescent shaped projections, K, with slight depressions K upon the upper side or surface. (See Fig. 3 of the drawings.)
It will be observed that these raised crescentshaped figures form rubbing-surfaces to the metal working-plate, and they present a larger friction-surface on the downward wash, while in the return movement the fold or crease of 5 the cloth caused by the downward movement, and which is that part rubbed by the cupshaped projections,will be divided and changed in the upward wash.
The upper part of the cup-shaped projections, extending boldly outward, constitute the active or working part of the board by present in g the greater frictional bearing to the fabric acted upon, and the lower part is a gradual taper, so as to present little resistance to the upward movement of the fabric, thereby obviating any great exertion of the washer in these movements. These cup-shaped figures in the sheet-zinc plate are embossed or stamped upon the surface thereof.
What I claim is The rubbing-plate provided with crescentshaped projections formed on its upper surface, as shown and described.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.
MELVIN M. TUCKER.
