IMPROVEMENT. IN STEAM WASH-BOILERS.

Specification forming part of Letters Patent No. 131,647, dated September 24, 1872.

To all whom it may concern.-

Be itlmown that we, GEORGE S. WRIGHT, of Racine, in the county of Racine and State of Wisconsimand ELIAS W. HARRINGTON, of

New'York, have invented a new and useful following is a specification: v

Figure 1 isa detail vertical section of our improvedjwasher taken through the line a: 00, Figs. 2 and 3. Fig. 2 is a horizontal section of the same taken through the line y y, Fig. 1. Fig. 3 is a horizontal section of the same taken. through the line 2 2, Fig. 1. Fig. 4: is a horizontal section of the cover taken through the line to 'w,'Fig. 1.

Our invention has for its object to furnish ing clothes and other cloths by steam, which shall be simple in construction, convenient in use, and efiectivetin operation, washing the clothes quickly and thoroughly, and without consists in the corrugated false bottom, provided with a downwardly-projecting rim, and one or more upwardly-projecting steam-conductors in the steam-conductors, made with their upper ends in the form of invertedcpnes;

a steam-escape valve with the cover, as hereinafter more fully described.

A represents an ordinary wash-boiler. B is a false bottom,- which is corrugated by having strips of metal bent longitudinally into an angular form attached to it, and having holes formedthrough the strips and through the bottom. These corrugations bottom B, so that the steam and water may The corrugations may be formed in the body of the bottom B ifdesired. To the edge of the bottom B is attached a rim, 0, which projects a suflicient distance below the bottom Bto form a reservoir for the water togenerate the steam. The rim 0 may project above the bottom B, if desired, to any desired distance. In the center of the bottom B is formed a hole, in which is secured the lower end of a tapering conductor, D, which may be made round, oblong, square, or of any other desired shape. Tothe upper end of the conductor D is attached a top, (1, made in the'shape of the frustum of an inverted hollow cone, the sides of which are perforated with numerous small holes. To the upper edge of the top d is attached the edge of an inverted cone, (1 having its sides more inclined than the sides of the cone d thus forming what we call a conical top to the conductor, which divides the steam, and projects it in numerous small streams upon the clothes lying upon the bottom B. E is the top steamer, which is made with a sunk bottom, so that it can fit into and be supported by the upper edge of the boiler. The sunk bottom has holes formed in its body and sides, as shown in Figs. 1 and 3, to allow the steam and water to pass through freely. In the center of the bottom of the steamer E is formed a hole, in which is secured a conductor similar to the conductor D d 01 F is the cover, which is so formed as to fit closely into the upper end of the boiler A and steamer E, as may be required. In the upper part of the cover F is formed a small chamber, G, in the bottom of which is formed a hole, which is covered with a drop-valve, H, which is held down by its own weight, and is kept from getting out of place by a cage, I. In the upper part of the cover F are formeda number of small holes.

With this construction, should too much steam be in the machine it will raise -the valve H and escape, the valve dropping back to its place as soon as the steam pressure is reduced-the whole to be used in combination or separately, as may be required.

' Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The corrugated false bottom B, provided with a downwardly-projecting rim, 0, and one or more upwardly-projecting conductors, D d 11 to adapt it to be used with a boiler, as and for the purpose set forth.
