1 Claim.V (Cl. 68-29) This invention relates to washboards for laundry purposes, of the reversible or double-faced type and the principal object is to provide a washboard of this type wherein the metal rubbing plates, at opposite sides of the board, will be bowed outwardly both longitudinally and transversely and shall be so arranged asto produce a bracing or strengthening effect when pressure is brought to bear on either of said faces, during the washing process,

In the drawing:

Figure 1 is a front elevation of a washboard made in accordance with the present invention.

Figure 2 is a vertical longitudinal section of the same, on the line 2-2 of Figure 1.

Figure 3 is a horizontal section on the line 3--3 of Figure 1, and

Figure 4 is a perspective view ofthe frame portion of the board with both rubbing faces removed.

Figure 5 is an enlarged fragmentary detail view, partly in section and partly in elevation, more clearly illustrating certain parts shown in Figure 2.

Figure 6 is a similar View more clearly illustrating the parts shown in Figure 3. In the drawing, the rectangular frame of the board is composed of the side bars l and Il,

' the top cross bar I2 and the bottom cross bar I3, all of which are centrally rabbeted, from end to end, on their inner sides as shown at H, l5, I6, and I?, respectively. The usual intermediate cross bar, indicated at I 8, is provided with a central longitudinal rabbet on both its upper and lower sides, the former being indicated at I9 and the latter at 20. The ends of the intermediate and bottom cross bars are mortised into the side bars and are securely fastened therein by nailing or in any other suitable manner, and the upper ends of the side bars are dove-tailed into the ends of the top cross bar-and fastened therein in a like manner.

The intermediate Vcross bar I8 constitutes the soap-rest and positioned above it is the brand Vboard A, the edges of which rest within the rabbets of the said cross bar I8, the top cross bar |2 and the side bars Il) and II, in the usual manner.

Extending longitudinally of the frame, midway between the side bars, is a relatively narrow longitudinal bar 2|, the front and rear faces of which converge, for a short distance, at both ends, to provide beveled portions as shown at 22 and 23 in Figure 4 and the outer ends of these convergingor beveled portions are fitted in recesses 24 and 25 formed in the confronting rabbeted portions of the intermediate and lower cross members, respectively, and in the paths of their rabbets shown in Figures 2 and 5. Particular attention is called to the fact that these from the ends of the longitudinal bar 2|.

The rubbing plates of the board, of which there are two, numbered 26 and 21, are formed of sheets of corrugated metal, of a Width greater than the space between the bottom walls of the rabbets in the side bars IIJ and I I, and of a length greater than the space between the correspond- 10 ing parts of the rabbets I1 and 20 in the bottom cross bar I3 and intermediate cross' bar I8, respectively,

These rubbing plates are positioned at opposite sides of the longitudinal bar 2| and have their 15 side edges positioned in the rabbets I4 and I5 of the side bars, and impinging against the bottom walls of said rabbets, while their upper and lower edges are correspondingly,positioned in the rabbets and Il of the intermediate and bottom 20 cross members, respectively, and at their centers are iirmly clamped between the beveled ends oi the bar 2| and the adjacent walls of the recesses 24 and 25, thus providing a rigid structure.

Attention is here called to the fact that the 25 rubbing plates are supported in the center by the bar 2| and that, since the end portions of this bar converge, to provide beveled portions 22 and 23, the rubbing plates are convex both longitudinally and transversely.

As a result of this arrangement, when pressure is brought to bear on a rubbing plate, the same will not give as it will be fully supported by the other rubbing plate and the bar 2|, against which it rests, also by its edge portionsv which rest in the rabbets.

What'is claimed is: Y

A washboard including an open rectangular frame comprising side and cross bars each having a longitudinal rabbet opening inwardly of o the frame, each of said cross bars. having an inwardly opening recess intermediate its ends and in the path of its rabbet,V a longitudinal bar mounted intermediate the side bars and connecting the cross bars, said longitudinal bar having 5 beveled end portions passing through the rabbets of the cross `bars and extending into said recesses, and a rubbing plate supported by the longitudinal bar, said rubbing plate having side marginal portions seated in the rabbets of the side members and end marginal portions seated in the rabbets of the cross bars, each of said end marginal portions being centrally clamped between a beveled endportion of the longitudinal bar and a wall of a. cross bar rabbet.
