WASH-BOARD.

SPECIFICATION forming part of Letters Patent No. 444,022, dated January 6, 1891. Appncfttiumedrlpi18,1890. serinNasLiazo. cromata) To alt whom it may concern.-

Be it known that I, MONTEZUMA SCOTT, of New Brighton, in the county of Beaver and State of Pennsylvania, have invented a new and useful Improvement in Wash-Boards, of which the following is a full, clear, and exact description.

The object of my invention is to provide a vitreous-faced Wash-board which shall possess in a high degree qualities of eheapness of construction, durability, efficiency, and cleanliness. I have discovered that if instead of making a Wash-board with its rubbing-surface of a single sheet of corrugated glass or earthenware, as heretofore, it be made of glass sections or of glazed sections of earthenware tile of limited size with corrugated faces a strong and durable article is had; and it is in such wash-board that my invention consists.

I am aware that heretofore it has been attempted to make wash-boards with rubbing faces of a single glazed tile or sheet of glass, but such articles were objectionable, because it was practically impossible to prevent the warping of the tile or sheet during its manufacture, so that the surface was irregular, and in case of the glass-faced board the size of the sheet made it liable to crack when in contact with hot water. All these objections are obviated by my invention, since being made in sections a rubbing-face of perfect regularity can be had, and when made of glass its sectional structure prevents it from bein gbroken by sudden expansion under heat.

The invention is illustrated in the accompanying drawings, in which- Figure l is a plan view of my improved wash-board, and Fig. 2 is a vertical section on the line II II of Fig. l.

Like symbols of reference indicate like parts in each.

The wash-board frame is made in the manner illustrated in the drawings, having end pieces 2, side pieces 3, and a supporting back plate 4, forming an inclosure for the glazed rubbing-surface. This rubbing-surface is composed of a number of glazed sections 5, which may be made either of glass or glazedearthenware tile, the faces of which are corrugated, and the edges are adapted to t neatly against each other, so as to form a continuous surface. In order to hold the sections in place in the frame, I provide the outside edges with projecting integral tongues 6,

which are adapted to fit in holes in the side and end pieces of the frame. The manner of fitting together the parts of the wash-board will be readily understood. The sections are placed together on the back board, the side and end pieces of the frame are secured around them, so that the tongue 6 shall enter the proper holes, and in order to hold the sections in place with still greater security I may form a nail-hole by notching the intermediate adjoining corners and may drive a nail through said hole into the back board. The sections are so set relatively to each other that the corrugations of the laterally-adjoining sections shall register, and in order to prevent tearing of the clothes, which might result from sharpness of the meeting edges b of the ridges on the tile, I make such edges rounded, as shown in the drawings. The sections are also formed at their ends a a, so that the parting between the sections shall be at the base of the ridges, and shall therefore be below the surface against which the clothes are rubbed.

It Will be understood that,instead of forming the sectionswith parallel grooves, as shown in the drawings, the rubbing-faces of the sections may be formed in the manner of the various styles of washdooards now in use. The raised meeting edges of the section in each case are preferably rounded. The wash-board so constructed is of great utility, is strong and durable, and the glazed surface thereof makes it cleanly and prevents it from injuring the clothes. The manner which I have shown and described for securing the sections together is of marked benefit, and I desire to claim' the same specifically7 herein; but it will be understood that other securing means may be employed and that I do not limit to such illustrated means the broad claim of this application, since- Vhat I claim, and desire to secure by Letters Patent, is-

A Wash-board having its rubbing-face composed of a series of corrugated or roughened vitreous-faced tiles or sections of limited size, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 15th day of April, A. D. 1890.

MONTEZUMA SCOTT.
