JEFFREY O. BENTLEY, OF PHILADELPHIA, PENNSYLVANIA.

'.IMPRovEMEN-r IN zwAsH-.BoA'RDs Specification forming part of Lettere Patent No. 182,546, dated September 26, 1876; application filed A February 9, 1876.

To all 'whom it may concern:

Beit known that I, JEFFREY O. BENTLEY, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a Hollow Radiatin g Metallic WashBoard, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention consists of a hollow washboard, for the circulation of steam. It is formed of sheet or cast metal, having in .its rear side a hot-air chamber, into which the air passes at the line of the floor, and from which it passes above the wash-board into the room in its heated state, produced from radiation from the rear side of the Wash-board. There is also radiation from the front, which assists in warming the room. I prefer making the rear side of the wash-board corrugated, as giving the maximum amount of heating-surface; but any other irregular form may be used, or the shape may be simply of box-form, if desired.

In the accompanying drawings, Figure l is a front view of my improved wash-board. Fig. 2 is a vertical section at the line-:1c cc of Fig. l. Figs. 3 and et show a modification of the invention.

Like letters of vreference in both figures inl dicate the same parts.

A represents a wall between two rooms. On the side there is a wash-board, B, formed of a sheet of metal, part of which is corrugated, to form steam-spaces c a ct, and part left plain, to form the front of the board, the edges of the sheet being closed and the joints made steam-tight by Asoldering or otherwise. The corrugations in front touch the front and hat part of the plate, but need not make a tight joint with the same, as the steam may circulate from one space to another, the object of the corrugations being to obtain as much radiating-surface for the rear of the board as possible, to heat the air in the chamber C.

There areindentations b at the line where the front extensions of the corrugations meet the vertical part of the sheet for the downward passage of any water formed by the condensation of the steam. Between the lower edge of the wash-board and the floor Dfthere is an air-passage, d, through which cold air passes from the room into the hot-air chamber C.

As the air becomes heated in said chamberand thereby rarefied, and ascends, it passes out of the same through the passage e, between the upper edge of the wash-board and the lower edge of the molding F, which is made of sheet metal, to increase the capacity of the hot-air chamber.

On the other side of the wall A there is a channels, I indent the sheet of metal at suitable distances apart, where theeorrugations meet the back and flat part of the sheet, as at the points b, to allow the free passage of steam, and thus prevent condensation along the lines of contact.

I do not conne myself to forming the rear. side of the sheet or sheets forming the wash: board with corrugations, as zigzag or other irregular forms will partially accomplish the end in view of increasing the radiating-surface; nor do I confine myself to making the front side of the board a plain iiat surface, as any desirable form may be used.

If desired, a plain box-form may be adopted for the wash-board when made of either sheet or cast metal, or the steam-spaces may be made by combining two sheets of corrugated metal together to form a panel, as in Figs. 3 and 4. The edges may be covered by strips of metal, except enough at one end to form an open communication with the boiler or heater.

My hollow wash-board or panel may be used for the circulation of either steam or hot air.
