PATENT LUTHER WENTWORTH, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN WASH-BOARDS.

Specification forming part of Letters Patent No. 129,913, dated July 30, 1872; antedated July 25, 1872.

SPECIFICATION.

To all whom it may concern:

Be it known that I, LUTHER WENTWORTH, of Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in'Wash-Boards; and I do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanying drawing, which, together with the letters and figures marked thereon, forms part of this specification, and in which' Figure l is a front view of a wash-board made according to my invention, and Fig. 2 is a side view of same with the removable side piece taken away.

Like letters of reference made use of in the several figures indicate like. parts.

Nature of the Invention.

clothes being washed.

It is the object of this invention to so construct the wash-board that when a portion is worn out it may be removed and replaced by a new part; and this invention consists in making the corrugations or ribseach separate and independent of the rest, and of a form so that they may be inserted in transverse slits or grooves cut in the face of the wash-board; and to the end that they may be readily re- .movable andreplaceable, the wash-board is made with one of its side pieces arranged to be readily removed and replaced, all of which will presently be more particularly explained and set forth.

GenemZDescription.

Toenable those skilled in the art to make and use my invention, I will proceed to describe the same with particularity, making reference in so doing to the aforesaid drawmg.

A is the backboard or body of the washboard. B are the sheet-metal ridges or corrugations, made of strips of sheet-zinc or other metal, bent into the form shown at Fig. 20f the drawing-that is to say, bent into a long trough, with the edges turned in, as at b. The face of the backboard A is sawn or cut transversely by a series of slits, a, arranged in pairs, one pair of slits to each of the ridges B. These slits are cut at an incline to the surface of the backboard A, and are inclined alternately upward and downward, so that each pair of slits if continued would cut out a triangular piece of the board. G G are the side pieces, which, prolonged, form the legs or supports of the wash-board. The side piece 0 is made in two parts, the upper part 0 and the lower part c. This upper part is fastened to the lower part c by screws or other contrivance, whereby it is rendered removable. The ridges B are attached to the board A by sliding the bent edges 1) into the slits a when the piece 0 is taken off, and are secured in place by attachiu g said piece.

When one of the ridges becomes worn, it is only necessary to remove the piece 0 and insert a new ridge, or to change the worn ridge to a different part of the board where the wear will be less, and to replace it with a less worn one. By this means a wash-board may be made to last a long time. I
