DAVID STEIN, on NEW YORK, N. Y.

WASHBOARD.

To all whom it may concern:

Be it known that 1, DAVID STEIN, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved WVashboard, of which the following is a. full, clear, and exact description.

This invention relates to certain improvements in all metal waslrboards, and more particularly to the construction of the frame of the wash-board and the means for securing in place the rubbing surface and the transverse shelf.

In my improved wash-board I form the entire frame, that is, the side bars and the top or transverse member, all of a single piece of channel-iron and the width of the groove in the channel is such that the corrugated metal rubbing surface is firmly held therein. The board is reversible and the soap-supporting shelves, on the opposite sides, are formed of a single piece of sheet metal which operates to hold the upper edge of the rubbing surface, as well as the body portion of the board above the shelf, in place.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of ref crence indicate corresponding parts in both views.

Figure l is a plan view of a. board constructed in accordance with my invention, a portion thereof being broken away, and Fig. 2 is a vertical section taken on the line 22 of Fig. 1.

In the specific form illustrated I provide the board with a frame formed of a single piece of channel-iron. This frame includes two side bars or rails 10 and 11 and a top or transverse rail 12. At the intersection of the top or transverse member 12 with the side rails, the channel-iron is provided with V-shaped notches in the flanges, so that the web may be readily bent and miter joints formed at the upper corners of the frame. The web of the channel is upon the outer surface of the groove and the channel comes toward the inner surface; thus, the groove in one side bar is directly opposite to the groove in the other side bar. The rubbing surface of the board is formed by a sheet 13 of corrugated metal, the corrugations of which extend transversely. The corrugations are of such size that they fit Within the Specification of Letters Patent.

grooves of the said members and the plate is held within said grooves without additional securing members over the upper and lower ends of the plate. At the lower edge of the plate I provide a transverse rod 1 1 which extends through the webs of the channels forming the side members and the outer ends of this rod are riveted, or secured in any other suitable manner, to prevent the side members from spreading apart. The lower edge of the corrugated sheet metal rubbing surface 13 is wrapped around the rod 14, so that the rod serves not only as a tie-rod but also to reinforce or strengthen the lower edge of the sheet'13.

The rubbing surface terminates a short distance below the upper end of the board and is held in place by the soap-supporting shelves. There are provided two of these shelves 15 and 1($,-extending outwardly from opposite sides of the board and each having its outer edge preferably bent upwardly to form a retaining flange and at the same time serving to strengthen and reinforce the free edge of the shelf. The two shelves are formed of a single piece of sheet metal, the center portion of which is bent upwardly to form a plait, fold or plicature 17. Thompper edge of the rubbing sheet 13 extends up into the open, under side of this plait or plicature and is retained therein by frictional engagement. The upper portion or body of the board above the shelves, is formed of a sheet metal plate 18, the edges of which extend into the groove of the side members and the transverse member of the frame. At the sides and upper edges of the sheet there are preferably provided flanges 19 which are of a width substantially equal to the width of the groove, so that the sheet is held closely adjacent one flange of the channel of the frame, and the free edge of thefiange 19 comes adjacent the opposite flange of the channel. The lower edge of the sheet 18 is folded back upon itself to form a plait 20, the lowermost portion of which comes adjacent the upper side of the shelf 15. The metal back supports the upper edge of the plait 17 so as to form a second. plait 21 receiving the plait 17 and bringing the free edge of the plate 18 closely adjacent the upper surface of the shelf 16. As the plate 18 is held from lateral movement within the channels and as the folds or plaits at the lower edge of said plate receive and rigidly hold the shelves and the upper edge of the corrugated sheet 18, it is evident that all of the parts are firmly held against relative movement.

Pivotally secured to the upper end of the board I provide a protecting baffle 22, the upper edge of which may rest against a person and prevent wet clothes, being washed, from coming in contact with the garments of the person doing the washin This batlie includes a substantially U-shaped wire frame 23, the free ends of which extend through openings in the side members of the board and constitute pivotal connections. The sheet metal body portion 23 has its free ed 'es wrapped around the outer edge and the ends of this wire frame, and at the edge adjacent the body of the board the sheet metal is folded or rolled back upon itself to form a reinforced bead 2a. The battle is pivoted in the plane of the board so that it may swing a limited distance in either direction according to which side of the board is being used.

All of the parts of the board are formed.

of metal, and preferably galvanized iron, the galvanizing preventing the parts from rusting and no rivets, bolts or other fastening means are employed, with the sole exception of the tie-rod let. There are no parts which can work loose or get out of adjustment and no parts which can deteriorate under the action of moisture, soap or ordinary chemicals used in washing.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1-. A wash-board having a frame formed of a single piece of channel iron bent to form two substantially parallel side members and a transverse top member, a body portion formed of two sections, the lower section formed of corrugated sheet metal with its edges extending into the grooves in said side members and constituting a rubbing surface, and the other section extending from adjacent the upper edge of said corrugated sheet to the transverse member of the frame, and two shelves extending outwardly in opposite directions from adjacent the upper edge of the corrugated sheet, said shelves being formed of a single piece of sheet metal having a fold or plicature inclosing the upper edge of the corrugated sheet, the secondmentioned section of the body having a fold adjacent its lower edge for receiving the first-mentioned fold.

2. A wash-board having a frame includ ing oppositely-disposed side members and a transverse or top member, each of said members having a groove or channel therein, a body formed of two sections, each having its edges disposed within the grooves of said side members and substantially in the same plane, and two shelves formed of a single piece of metal having an upwardly-extending fold or plicature receiving the upper edge of one of said body sections, and the other of said sections having a fold adjacent its lower edge for receiving said first-mentioned fold.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DAVID STEIN.
