To (LZ/ whom, zz; may concern:

Be it known that I, THOMAS RoDnRIoK, a citizen of the United States, residing at Columbus, in the countyof Franklin and State of Ohio, have invented certain new and useful Improvements in HeatingStoves; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates more particularly to that class of heating-stoves in which gas, natural or artificial, is the fuel; and the aim of the invention is to provide an improved stove of this sort that shall be of economical and simple construction and yet yield large results.

A heating-stove is obviously effective in proportion to the area of surface it presents against which the air to be heated can im pinge and be rapidly diffused. There is no difficulty in securing an abundance of surface where expense is not much of a consideration; but it has taxed the ingenuity of inventors and manufacturers to obtain a construction in which there is large air heating or radiating surface, small cnbical content, and at the same time simplicity and economy of construction, so as to bring the stove within the reach of persons of small or ordinary means.

In the accompanying drawings, in which I have shown embodiments of my improvements, Figure l is an end View. Fig. 2 is a central vertical sectional view taken on a plane indicated by the line :n Fig. 3. Fig. 3 is a horizontal sectional View taken on a plane indicated by the line y y, Fig. 2. Fig. a is a side and sectional view of the upper part of the stove only, showing attachments that can be applied for cooking purposes. Fig. 5 is a top plan View of what is shown in Fig. 4,v the end being broken out and shown in section.

Like characters of reference in the several views designate corresponding parts.

Referring to Figs. l, 2, and 3, the character l designates the front, 2 the back, l the top, and 3 the ends or sides, of the stove. The front is closed over its entire area except for a suitable small opening below the burner, like that indicated at l, as usual in stoves of this kind and as well understood, to admit air to support combustion, and the back is likewise closed except fora suitable opening in its lower portion for the escape of the products of combustion. The closed top 4 joins the front and back. The front. can be snitably ornamented and provided with mica lights to render visible the gas-llame. The sides or ends 3 are made with long large openings, the edges of which are approximately parallel to the general direction of the front, top, back, and bottom of the stove, and such openings are of the form of the cross'section of the hollow prism 6, hereinafter described. Extending between and secured to the ends or sides 3 is a hollow prism G, of sheet metal, completely open from end to end and having its edges at the ends uniting with the edges of the openings in the ends 3. This prism constitutes an air-heating chamber, and the front side or wall thereof is only slightly inclined to cut the vertical plane passing through the burner, and the lower portion of this slightly-inclined front wall is furnished with a facing of asbestos to protect the metal against the intense heat of the fiame.

The upper end, as well as the vertical sides, of the aiihheating chamber is solid or closed, while the lower end is perforated, as seen at Gn.

Below the airheating chamber is what might be termed a cold or fresh air chamber 7, that is separated from the burnerchamber by a vertical partition 8 and a horizontal partition 9. This coldair chamber is preferably provided with two collared openings, one of which is shown to have a removable c-ap and the other with a pipe for taking air. The air to be heated can be taken either from the room in which the stove is located or from the exterior of that room. If a valve is put in the outdoor air-pipe, the air can first be taken from outdoors only and then from the room only, orit can be taken continuously from outdoors and the supply regulated.

Referring now to Figs. 4 and 5, in which I show how attachments can be applied to my stove to permit cooking, lO designates an opening that can be covered with a removable cap. ll is a damper for retarding the draft when increased heat for cooking or ediblewarming purposes is desired at the top of the stove. To form an oven, parallel channels IOO or ways 12 to receive sliding doors 13 are sen cured to the ends of the stove adjacent the upper ends of the air-heating chamber, and a shelf 14 is supported on horizontal ledges 14a, secured along the inner sides of the chamber. The shelf and the doors are only to be temporarily applied and can be taken out When the heater is to' be used forits primary purpose. With these cooking attachments the stove will be especially acceptable to those.v who from necessity or choice reside in one or a` few rooms. will be observed that the matter of putting in the heating-drum not only simplifies the work of construction and eects a saving in the material employed, but also secures large increase in the air-heating surface and permits a rapid exit and diffusion of the air heat` ed within the drum.

-I do not herein claim the above-described attachments permitting the cooking or warm ing of foods, but have sim ply illustrated them for the purpose of showing a use to which my construction of heating-stove can be very easily put if these attachments be used. vWhat I claim, and desire to secure by Let;- tersv Patent, is

lLjlna heating-stove, the front and back Aside from this, however, it'

walls substantially parallel to each other, a top, and ends or sides, large openings in said sides or ends conformingr in shape to the general contour of the edges of the ends', and a horizontally-arranged air-heating ch amber of prismatic form free and open from end lto end with the edges of its ends uniting with the edges of the openings in the ends 0r sides of the stove, substantially as shown.

2. In a heating-stove, the front and back Awalls, the top, and the sides or ends, large openings in said ends or sides conforming in shape to the general contour of the edges of the said sides or ends, a horizontally-arranged air-heating chamber of prism-atie form free and open from end to end with the edges atv
