This furnace construction combines the properties and advantages of iron furnaces those of the tiled stoves. The pleasant, uniform warming by the latter is connected with rapid heating by the former.

The furnace is shown in Figures 1 to 6 of the accompanying drawings.

The furnace is fired on a flat grate with fine, ground grate bars for each type Fuel is set up in a suitable, free joint width; from an artificial fire with Regulation is removed, so that the operation with the least possible attention and skill can be done, and because of the necessity which the System in terms of ventilation brings with it a fairly large one as soon as possible To make a fire and heat it for as short a time as possible.

The fire gases are distributed over the grate by going through some chamotte shaped stones F standing apart from one another, which at the same time support the upper masonry and cause the fire air to be distributed in such a way that the same in the LJ-shaped cross-section Fig. 3, a, b , c, d, e, f, g, h between the masonry c, d, e, f and iron jacket a, b, g, h, partly also in the opening O through the middle of the masonry, can rise up to then under the iron ceiling D, Fig. 1 and 5, along downwards in the cross section, Fig. 3, i, k, I, m, n, o, f, q to rise, between masonry 11, ο, p, q and iron jacket i, k, I, m. From below the pipe R then leads the used gases to the chimney.

Of particular importance here is the peculiar, slit-like stretched one Shape of the trains and the "practically determined" dimension of the width of about 40 mm what it is achieved is that of cast iron or wrought iron in the strongest fire Sheath made from sheet metal can never become red-hot. A specially designed one for testing this proposition Furnace, the entire combustion chamber of which was packed with bohemian brown coals over grate, which with Coals were mixed, did not become glowing in spite of the great fire achieved with it.

This arrangement of the trains also allows the oven to be cleaned extremely quickly and easily. For this purpose, the ceiling D is divided into several parts, which rest in a "sand seal" and can easily be lifted off with the attached handles. A wooden frame is then inserted into the ceiling D , which is to be added to each stove, which also has a fine slot above the slot-like lines through which a wire is inserted with a brush attached below; by means of these peculiar devices one achieves a very quick and convenient cleaning, without dust and dust being able to penetrate into the apartment.

If the fire is still fully burning, the doors TT, Fig. 1 and 2, are closed as soon as the desired temperature has been reached in the room to be heated. The stove is absolutely safe because there is neither a flap nor a slide from the grate to the chimney. B. occur in Meidinger furnace, is completely impossible with these arrangements. After the doors TT are closed, the heat is retained in the stove by opening door K at the rear of the stove at the same time, so that the stream of cold air indicated in FIG forms the seal against the escape of heat. In this way the stove can actually be left open downstairs day and night and, with the exception of the short time when the fire is being used, it can be ventilated continuously without the room being cooled down.

With this arrangement it is made possible that that has since been lost in the chimneys unused to fully utilize the heat left on air - renewal; twenty to twenty two The chimney can be fully used for air renewal for hours; With this device one has an extremely simple and cheap process, the air renewal Free of charge in every apartment with avoidance of all other artificial devices to introduce.

happened only to a small extent, since with the chimney fully open the combustion simply had to stop. In other cases, so-called lock chimneys have been placed next to the actual chimney; the slight warming of the same brought about just as little air renewal, while here with the anemometer 24 to 30 cbm air renewal per hour were found on the fully open chimney. With the iron stoves or tiled stoves that are now customary, the heat always rises upwards and is stored under the ceiling of the room. By means of the present improvements it is possible to pull down this heat and use it. If you open the door of the stove at K and suck out the cold air on the floor, you are able to let fresh air flow in from the outside, either through an opening L, Fig. 2 and 6, which the fresh air first leads behind the stove so that it is warmed up there, or it happens through several smaller openings, which are made close to the ceiling of the room and allowed to go outside. The incoming fresh air mixes in both cases with the warm layers of air on the ceiling, and, as the chimney sucks the lower layers of air away from the floor, the upper layers of air gradually sink down. The inconvenience of having the head in warmer layers of air and the feet in cold air with the current heating is thus considerably reduced; for the cold air from the floor is carried away and the warmth of the upper floor is softened by the fresh air flowing in. The fuel savings can be pushed very far with this system; for there is no difficulty at all in increasing the number of iron rings of the mantle at will, so that the furnace can easily be adapted to all cooling conditions at any time, even afterwards; This, too, is a characteristic advantage over the iron stoves obtained in solid, closed shapes and dimensions from the shops. The furnace can be installed with or without a heat tube on request. Finally, the fact that the. Heating surfaces do not get glowing, the attachment of an openwork jacket at a distance of about 50 mm from the radiator. P ATEN τ claims: 1. The arrangement of slot-like trains between bad and good heat conductors for the purpose of simultaneous rapid release and storage of heat, as well as for the purpose of prevention the glowing of the metal plates serving as good conductors, as described above. 2. The arrangement of ducts at the foot of the stove from the room to the chimney for the purpose Air renewal in the room while at the same time retaining the stored heat, as described above. 3. The arrangement of channels on the stove from outside through the stove to the room respectively under the ceiling of the room from the outside into the room for the purpose of renewing the room air, at the same time making it useful the warm air layers on the ceiling while avoiding drafts and with simultaneous opening of the duct specified under 2 from the room into the chimney, as described above. 4. Convenient cleaning devices with inserting a wooden frame into the ceiling of the furnace when the entry of . Reputation and dust in the room while cleaning, as described above. 5. The utilization of all existing, directly heated chimneys as fans for air renewal when the chimneys are fully open for 20-22 hours of the day, as described above. 6. The construction of the union of all these advantages in one interlocking, in ■ closed system of a ventilation oven. For this purpose ι sheet of drawings.
