APPARATUS FOR COOKING BY STEAM.

Specification of Letters Patent No. 24,178, dated May 24, 1859;

2, is a transverse vertical section of do.,

taken in the line y, y, Fig. 3. and, Fig. 3, is a horizontal section of the same taken in the plane indicated by the lines a, a, Figs.

1 and 2.

Similar letters in the three figures refer to corresponding parts in my invention.

This invention consists in arranging over a steam boiler, that is to say, over a closed space formed in the lower part of a box with a flat bottom, a steam chamber, which communicates with the boiler by means of a slide which can be operated from the outside, and part of which forms a separate compartment or oven sufciently smaller than the chamber that the same, when the chamber is filled with steam, is exposed to the heat of the same from all sides, that side excepted where itis provided with a door, the whole being so arranged, that the chamber serves to cook articles in the steam or in dry air and that the oven serves for baking.

To enable others skilled in the art to fully understand, use and construct my invention I will proceed to describe it.

A, is a box or shell made of sheet brass, sheet iron, or any other suitable material, its top being made concave so that the condensed steam runs down on the sides, and the lower part of this box is separated from the rest by means of a false or double bottom B, so that a square C, is formed which serves for the steam boiler. Water is introduced in this space by means of a tube a, which is closed by a cap, and another tube o, communicates with this boiler in which a ball o, lays in a seat formed by a concave partition d, with an orifice in the center (see Fig. 2), so that the steam, if its pressure becomes too large can escape by raising this ball, the weight of which is according to the strength of the material used in making the shell A.

In order to empty the boiler C, a cock or tap D, is inserted in the same which serves also to draw oill hot water. rIhe space above the boiler Jforms a steam chamber E, which communicates with the boiler by means of a slide e, which is operated from the outside by a knob f, and a series of rods g, is attached to the bottom of the steam chamber so that if a plate or dish or any other vessel be placed on the same, the hot air or the steam has free access to it from all sides. A similar series of rods 7L, is arranged higher up in the steam chamber, so as to form a shelf.- One side of this chamber E, is closed by a door F, and the other end contains the square oven Gr, which is also provided with a close shutting door H, and which is sutliciently smaller than the chamber E, so that the steam or hot air has free access to the same from all sides.

A handle I, is attached to the upper part of the shell so that the whole can be carried from place to place.

The operation is as vollows: After the boiler C, has been filled with water the whole is placed on a stove or furnace or it may be heated with an alcohol lamp, and the articles to be cooked are placed in the chamber E, and such articles as are intended for baking are placed in the oven G. After the water in the boiler begins to form steam, and when the pressure of this steam is high enough so that its heat is sufficient for cooking or baking the articles in the chamber and in the oven, the slide e, is opened and steam is admitted in the chamber E. If the pressure of the steam rises too highit lifts the ball c, and some of it escapes. The articles in the chamber E, may however be cooked without opening the slide e, as the air in the same becomes suiiiciently hot for many purposes, and by means of this invention all articles may be cooked or baked without coming in immediate contact withthe tire, so that no danger exists of burning the articles by exposing the same to the heat of the re for too long a time or by having a stronger lire than would be required.

Having thus described my invention what and one end of which contains the oven G, I claim as new and desire to secure by Let` the Whole being arranged substantially as ters Patent, isn and for the purpose specified.

The Within described arrangement of a l H.` W; HoRToNl 5 steam boiler C, in combination with a steam Witnesses:

chamber E, which communicates With the J. L. RAWSON, boiler by means of a. slide e, or its equivalenti l H. B. CHASE.
