No. 520,4'70. Patented May 29, 1894.





SPECIFICATION forming part of Letters Patent No. 520,4'70, dated May 29, 1894. Application filed February 21, 1894. Serial No. 501.028. (No model.)

IFO all whom it may concern:

Be it known that I, GEORGE YINGER, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of cooking appliances which are known as steam cookers; and the primary object of the invention is to so improve the construction of such base and consists of a devices that they will be more useful and effective.

A further object is to provide means for more eifectually shutting o the steam from the cooking chamber, or regulating the flow so that various amounts of steam may be applied as the nature of the food requires.

To these several ends my invention consists of certain improved features of construction and combination of parts which will be more fully described hereinafterl and finally embodied in the claims.

In the accompanying drawings-Figure 1 represents a perspective view of my invention, showing the cover or upper section removed. Fig. 2 is a longitudinal sectional view; and Fig. 3 an enlargeddetail showing the arrangement of caps for regulating the supply of steam; Fig. 4 a section on x-w of Fig. 2.

The deviceis formed of two sections a and `b. The former section, a, is the bottom or pan-shaped vessel provided with the handle's or cars a' and spout 0,2, which latter device extends out from one side and communicates with the interior of the Vessel by means of the opening as. The section b is substantially the same as its companion and is provided with the flange b' extending around its lower edge, the said edge being adapted to fit within the upper edge of the section a, and the fiange to bind thereagainst, thereby making a steam-tight joint. The upper side of the section b, is provided with a button 52 by which the section may be lifted.

c indicates the cooking or food tray, which consists of asheet of metal, preferably tin, of such a size that it will snugly fit within the bottom section a, and provided with the downwardly extending fianges c' which engage the bottom of the section a and serve to support the tray. These flanges areof a size sufficient to raise the tray about one-half the height of the section a, and the edges of the tray engage the sides of said section so as to admit no passage of steam between the two.

Formed in the tray c, are the openings d, which are adapted for the passage of steam and which are preferably four in number, though this may be varied to suit the desire of the user, or the exigencies of the occasion. Each of the openings d, is provided with a conical perforated tube d' which projects upwardly to a point very near the top of section b. The tubes d' are frusto-conical in shape and perforated at a pointbetween their ends, the said ends being left open.

h indicates a series of tapering sleeves, which are four in number, one for each of the tubes d', and which are adapted to [it over said tubes so as to be capable of tnrning thereon, a stud 71,2 being provided, whereby it is prevented from coming off. These sleeves are also open at each end and are shorter than tubes d', their upper ends terminating below the upper ends of said tubes, and are formed with the perforations h' therein, which are capable of matching with Tthe perforations in tube d', and of being moved out of alignment therewith upon turning sleeve h, thereby allowing the steam to escape or cutting it off at will. By means of the arm or stud i, this turning of sleeve h, may be effected.

Secured rigidly to the tube d' at its base, is the stud k, which fits into the horizontally elongated slot k' of the sleeve h, and whereby the sleeve is prevented from excessive movement.

Adapted to fit over the open end of tubes d' are the caps e, whereby the passage of the steam out the ends of the tubes may be regulated. Also, by this means, the steam may be forced to go out the sides of the tubes and to spread laterally, provided the sleeves h be properly adjusted. These caps are so shaped that they will fit snugly over the end of the tube d' and extend nearly down to the sleeves h.

The device, g, of Fig. 1, consists of a tube of such length that it will reach longitudi- IOC nally from one of the tubes d', to another, and having its ends bent down at g' so that they may fit over the upper ends of the tubes d'. This tube is provided with the perforations 92, by which the steam is allowed to escape.

The primary purpose of this device is to provide a support for cooking utensils when arranged within the cooker, and when the tray c is covered with food. The caps e are provided for use when it isnot desired or convenient to use tubes g, and When it is desired to prevent the escape of steam through the open ends of the tubes d'. Thus if the tubes g interfere with the dishes, they maybe removed and caps e used in their stead.

To cook food with my appliance, the section a is filled with water until it rises to a point just below the tray c. This may be ascertained by the spout a2, and by means of this device the section may be filled. The food is then placed in a suitable receptacle and put upon the tray c and tubes g, after which the top b, is arranged in place and the appliance placed upon a stove. The devces over the tubes d' are then regulated according to the nature of the food being cooked so as to throw out the proper amount of steam, which acts on the food and effects the cooking Operation.

It will be seen from the foregoing that my invention is exceedingly simple and efective, and that food cooked by it will be better prepared than ordinarily, since the arrangement of the steam tubes which I employ forms a' much better mode of distributing the steam. By my invention food may be placed in fine china dishes and then in the cooker, and, after cooked, removed and placed upon the table without further handling, thus saving the use of pots and other cooking utensils.

Having thus described my invention, what 1 claim as new, and desire to secure byLetters Patent, is-- 1. A steam cooking apparatus comprising a water chamber, a food chamber above the same, a series of perforated tubes arising from the water chamber and adapted to distribute the steam throughout the food chamber, and a detachable perforated tube adapted to extend from one of the first named perforated tubes to another, and having its ends bent to fit over the said first named tubes, substantially as and for the purpose described.

2. A steam cooking apparatus comprising a water chamber, a food chamber above the same, a series of perforated tubes arising from the water chamber and having thereon ya stud, and a revoluble -sleeve fitting over each of the perforated tubes and having perforations therein capable of registering with those in the tubes, and a slot in the sleeves in which the studs of the tubes are respectively arranged, whereby the steam flowing through the perforations of the tubes may be cut oif and whereby the rotary movement of the sleeves is limited, substantially as described.

8. A steam cooking apparatus comprising a water chamber, a food chamber arranged above the same, and a perforated tube communicating with the water chamber and projecting into the food chamber, said tube being bent to form a support for the dishes contained in the food chamber, substantially as described.

4. A steam cooking apparatus comprising a water chamber, a food chamber arranged ab'ove the same, two short sections of tubing communicating with the water chamber and arising vertically into the food chamber, and a perforated detachable tube extending horizontally from one of the short sections of tubing to another and having its ends bent downwardly so as to fit over the short sections of tubing, whereby dishes may be supported upon the horizontal portion of the detachable tube, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my Signature in the presence of two Witnesses.
