GAS STOVE AND RADIATOR.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed April 3,1906. $erisl No. 309.587.

To all whom it may concern:

Be it known that I, FLoRnN'r DE GRAUWE, manufacturer, a subject of the Belgian King, residing at 80-82 Jordaensstraat, Antwerp, Belgium, have invented new and useful Improvements in Gas-Stoves and Radiators; and I do hereby declare the following to be a full, clear, and exact description of the same.

My present invention relates to gasstoves and radiators, the object being to provide a heater of this kind wherein the combustion gases are brought from the usual burner laterally on either side of the stove into boxshaped containers, whence said gases flow through a series of horizontal heating pipes, in contact of which the air of the room is strongly heated, a further object being to provide a gas-radiating stove, wherein the hot combustion gases are uniformly distributed throughout the entire stove prior to their discharge into the chimney.

In the accompanying drawings: Figure 1 is a front elevation of the stove, Fig. 2 is a vertical section thereof, Fig. 3 is an end view from the right-hand-side with the side plate removed to show the inner construction of the flat containing box. Fig. 4 is a similar view from the left-hand-side, and Fig. 5 is a horizontal section of the left-hand-side box.

Referring to the drawings, 1 indicates the usual heat reflector, which may be of any well-known form and construction, and above' which is arranged the horizontal gas-burner 2. The combustion air is brought to the latter through the space behind the reflector 1 in the-direction of the arrow 3, and the radiating heat is reflected by the reflector 1 in the well-known manner. So far, my stove is similar to' the well-known constructions. Now the combustion gases instead of being discharged directly into the chimney, or into a short or other pipe, are brought laterally on either side below the upper reflector 4 into a right-hand-side box 5 through openings 7, 8 respectively. The right-handside box is divided into two compartments by means of a substantially horizontal partition 9, the lower compartment being connected by' means of a pipe 10 to the opposite box 6, divided into two compartments by means of a substantially vertical partition 11. The upper compartment of the box 5 is further connected to the left-hand-side box 6 by means of a pipe 12. Each box 5 and 6 is provided with an upper passage 13, 14 respectively, through which the combustion gases are brought into the common discharge pipe 15 leading to the chimney. Said discharge-pipe is provided with an air controlling device, consisting of a movable sleeve, rotatably mounted on said pipe and provided with apertures or slots 16, adapted to register in a more or less large extent with similar apertures or slots provided the discharge pipe.

The operation of the stove is as follows: The gas being lighted at the burner 2, the heat is first reflected on the reflector 1, while the hot combustion gases are brought below the upper reflector 4 laterally on either side. At the righthand-side of Fig. 1, the hot combustion gases enter the flat box 5 through the opening 7 (see arrows a) and arrive into the lower compartment thereof. Thence, the hot gases flow through the horizontal obliquely arranged pipe 10 into the left-handside box, that is, into the left compartment thereof (see arrows a), wherein said gases flow upwardly into the passage 14 and thence into the adjustable discharge pipe. At the left hand side of Fig. 1, the hot combustion gases enter the flat box 6 through the opening 8 (see arrows b), and flow upwardly into the right compartment thereof to pass through the horizontal obliquely arranged pipe 12 into the right-hand-side box 5, that is into the upper compartment thereof, whence said gases flow through the passage 13 into the dis charge pipe.

From the construction and arrangement it will be easily understood that the heat of the combustion gases is most practically utilized for heating the air of the room flowing around the pipes 10, 12 and upper passages 13, 14, and that the stove is heated most uniformly through out.

Having fully described my invention, what I claim and desire to secure by Letters Patent is In a gas-stove of the class described, the combination with the main reflector, the upper substantially horizontal reflector, and the gas-burner, of two side-boxes, an opening in the inner wall of each box and in the bottom part thereof for the entrance of the hot combustion gases, a substantially horizontal partition in the right-hand-side box, whereby the latter is divided into upper and lower compartments, a substantially vertical partition in the left-hand-side box, whereby the same is divided into right and left compartments, :1. horizontal obliquely arranged pipe leading from the lower compartment of the right-handside box into the left compartment of the right-hand-side box, a horizontal obliquely arranged pipe extending from the right compartment of the lcft-hand-side box into the upper compartment of the right-liand side box, suitable discharge passages leading from each side-box, and a common controllable, discharge pipe for leading the combustion gases from said passages into the chimney, substantially as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

FLORENT DE GRAUWE.
