IMPROVED WASH-BOARD.

Specification forming part of Letters Patent No. 18,965.. dated December 29, 1857.

To all whom it may concern.-

Be it known that we,WrLLIAM M. GALUsHA and BENJAMIN W. SAEEORD, of Arlington, in the county of Bennington and State of Vermont, have invented a new and Improved Wash-Board; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the anneXed drawings, makinga part of this specification, in Which- Figure 1 is a front or face view of our iniprovenient. Fig. 2 is a longitudinal central section of saine. Fig. 3 is a horizontal central section of saine. Fig. 4 is asection ofthe corrugated plate in perspective.

Similar letters oi' reference indicate correspending parts in the several figures.

This invention relates to an improvement in that class of Wash-boards in which corrugated sheet metal is used for a rubbiugsurface.

The improvement consists in the peculiar forni of corrugations, whereby the board is rendered quite stiff, a good rubbingsurface obtained, or one well calculated to subject the clothes `as they are pressed upon and passed over it to a requisite degree of friction, and at the same time afford proper channels for the escape or passage of the water, so as to prevent the splashing of the same.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents the frame of the wash-board, which may be constructed in the usual way# viz., two side pieces or strips, a a, connected by cross-bars b b. The frame may be constructed of wood.

B is the corrugated portion of the board. This is formed of sheet metal corrugated. The corrugations may be formed by striking up the metal plate with dies, or in any proper or desirable way. The corrugations are formed of a series of elevations, c, and depressions d, the elevations and depressions being in parallel rows and in alternate positions with respect to each other, as shown clearly in Fig. 1. The forni of the corrugations is oblong, the ends e and sides f being inclined and the edges g somewhat rounded. The rounded edges g are shown clearly in Fig. 2, each elevation forming a figure approximating to a semi cylinder pointed at each end, the ends of the elevations in one row overlapping the ends of those in the adjoining rows. (See Figs. l and 4..) By this form of oorrugation channels, as indicated bythe arrows, are formed for the escape of water down the plate B into the tub. The part B has its edges fitted in grooves h, formed in the inner sides of the strips a a and crossbars b b, and is thereby secured within the frame A. (See Figs. 2 and 3.) Sheetzinc will probably be used for the part B. At least this would be the most desirable material. By having thecorrugations of the form as shown the part B is rendered quite stiff, and will not yield or give as the clothes are pressed upon it. The corrugated sheet-metal plates hitherto used for such purpose, so far as we are aware, have been corrugated so as to forni parallel iiutes extending entirely across the plate. This form of corrugation renders the plate very elastic or yielding, and also has a tendency to splash the Water, no channels being formed for its escape down the plate into the tub. By ourimprovementtlieseobjections are obviated.

Ve do not claim, broadly, the employment or use of a corrugated sheetmetal plate for the rubbing-surface of a wash-board, for they have been previously used; but

We claim as new and desire to secure by Letters Patent- Oorrugating the sheet-metal pl atein the form specifically as herein shown and described, for the purpose set forth.
