PATENT LETTERING

CLASS 36: Heating systems.

Patented in the German Empire on November 13, 1886.

The invention aims at the direct (primary) and indirect (secondary) Low-pressure steam heaters (steam boilers and radiators) have the option to give, by means of a single apparatus, by simple repositioning of the same, the most varied To bring about functions with regard to the combustion and heating air.

To achieve this purpose, a drum α made of sheet metal or other suitable material is installed at the lower end of the radiator (ribbed register, coiled pipes, steam ovens, etc.), Fig. 1 and 2, in such a way that it is in conjunction with the wall of the room m on the one hand and the one made of insulating material ^: Mantei η on the other hand or in a similar arrangement a shaft closed at the bottom / forms within which the radiator is located. Of three openings or recesses x, y and \ in the drum a, each offset by 45 ° from one another, one of them corresponds laterally to a channel made in the wall m , which opens out into the open. from there fresh air is supplied, the second (upper) with the heating shaft, the third through an opening in the. Isdlirmantel around the network of the intent or. Ornamental grille r through with the room and the room air in it. Within this fixed drum α lies a second drum b, concentric to it and easily rotatable, almost in contact with it. It also has three openings X ₁ , y ₁ and ^ ₁ corresponding to the three openings x, y and ^. By rotating and positioning this drum in different ways, one can achieve. Now the most varied of successes, as shown in I to V , and you have it in your hand, by simply turning the drum a quarter or a quarter. Eighth circle to supply the room air, fresh outside air or both mixed to the radiator, to block the opening y and thereby establish a direct connection between the room and the outside air, whereby the heating is opened by interrupting the circulation. Activity is set, or finally ventilation, circulation and heating are switched off altogether. During all these positions the steam passes through the radiator unhindered, but without being able to give off heat due to the lack of air circulation when the opening y is closed. A pointer s sitting on the axis of b plays on a scale attached to the side of the attachment grid r , so that the current function of the apparatus can be recognized at any time from the position of this pointer.

On the same principle rests that for the regulation of the combustion air of the primary Radiator (steam boiler) constructed apparatus, Figs. 3 and 4.

The outer (stationary) drum a has the openings ξ, ti and ζ. ξ is in connection with the ash fall (space under the grate), υ corresponds to the outside air and ζ continues in a pipe or a canal, which flows into the fire trains, the fox or the chimney at a suitable point. The drum, which can be rotated in α, has only two openings in this case. In the position / α, the fire receives supply from

fresh air through the grate gaps or in any other popular way. If with increasing pressure in the boilers of the apparatus in the position Ha, placed, so the cross-section is obtained because of the reduction of ξ · firstly the fire less air, secondly flows Quantum cold air, by ζ in the flues and thereby attenuates the fire by Generation of return. In the event of excessively high pressure, the regulator is brought to position IHa ₁ , in this way the air is completely withdrawn from the fire and at the same time the boiler is cooled by letting a large quantity of air flow through ζ into the flues.

The shape, mutual position and size of the openings x, y and ^ respectively. ξ, υ and ζ can be modified at will, depending on the intended purpose; the inner drum can also be made stationary and the outer drum movable and rotatable.

The drum b respectively. β can be set up automatically in all cases, depending on the vapor pressure and the resulting temperature.

Such an arrangement is sketched in FIGS.

Within the β by a counterweight ρ auszubalancirenden a drum vessel, t is attached to the appropriate place, by means of which tubes uu and the hollow axis n> in connection with the boiler is. While the vessel, t filled at normal pressure in the boiler with air and the apparatus characterized the position Ia. Assuming that, with increasing pressure, the vessel fills more and more with water, compressing the air contained therein, 'turns the drum as it descends and more and more dampens the fire.

This automatic regulation can be arranged in the most varied of ways, e.g. B. by transferring the heat of the rooms to be heated from a thermometer from to. electrical path to the apparatus and the resulting automatic Switching by means of electromagnets and the like.

Claims (3)

Patent Claims: 1. To regulate the heating air in water and steam heaters, the arrangement of two rotatable, concentric, almost touching drums α and b, with openings x, y and ^ appropriately distributed on their circumference, which by their different types, by rotation of the one Drum caused mutual position to allow the distribution or withdrawal of the heating air in the heating apparatus in such a way that the openings located on the stationary drum directly or through channels connected to the corresponding points are closed or opened by the rotatable drum or its openings, whereby depending on the different Combination of room air, outside air or both heated, outside air supplied or the heating switched off completely. 2. The application of the device specified in claim 1. for regulating the Combustion air in steam boilers. 3. The automatic adjustment of the drum b by means of any known apparatus, which is dependent on the steam pressure or the temperature of the heat-transferring medium (water) or the heated rooms.
