. To all whom may concern:

Be it known that we, OTTO Onsrsnnnr: and KARL CONRAD MiiLLER, subjects of the King of Bavaria, both residing at Zweibriicken, Palatinate, Bavaria, Germany, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specificatiom'reference being-hadwhole burner or mixing chamber has to be swung out when put out of work, are

avoided with this invention, the burner being now so constructed that vonly a small part ,of the burner has to swing out.

As only a part of'the burner has to be removed and can be replaced by a closing plate during the blast period of a stove, it is poss'ble to build the immovable part of the burner in such a way as to obtain the best conditions for a rapid and most eliicient mixture of gas and air, and also for the best regulation of gas and air admission. The admission of gas and air is regulated by a conical or otherwise shaped valve placed in the immovable part of the burner. I

This invention provides therefore an apparatus which is not only a convenient and practical means of shutting ofi the gas when putting the stove on blast, but as the main part of the burner remains fixed, it is pos-- sible to build this part so as to obtain an efiicient gas and air mixture and at'the same time send quickly large quantities of gas into the stove where it is completely burned. \Vith this new burner it is not only easier to change the stove from gas to blast, but also will the heating period be much shorter the efficiency being better than before.

Where as formerly the gases were throttled down before entering the cowper apparatus, where they mixed with the comburent, this invention transforms the pressure of the gas current in speed by means of the conical valve which forms a main part of this invention. The high speed of the gas then draws in the necessary combustion air in one or two steps.

In the drawing: the figure shows a central sectional view of the gas burner. In this swung around the spindle 1? drawing the gas is shown entering the burnerfrom the top, naturally any other position is from the position of the main gas pipe;

The outer case a which is strongly supported or suspended in a fixed distance'oi possible, this depending only the cowper stove carries inside throughthoshaft d and ribs 0 a con cal valve 17 When vworking valve 5 is in the posithe valve b is shown tion marked by dotted lines, so that as can pass from the m chamber 0. Through the special form of the valve 1) and the mouthpiece f the twyer 2' to the com ustion flow of the gas is changed in velocity. when leaving the casing a and by this velocity combustion air is drawn in, primary and secondary combustion air behind the gas outlet. a

In the drawing the primary air is enter-1,

ing through the ring channel 9 while' the necessary secondary air enters behind the' part h by. channel is, being drawn in either by the aspiration of gas current or'by the chimney draft of the cowper. Movable shuttersfl or m allow the regulation of the air inlets. i

It is important that the burner mouth.- piece 2' is divided into several parts and that when puttingthe burner out of work a part of-it can be swung out or removed, so

as to close the cowper opening by a plate It is best to combine the removable part of the burner and this cover plate i as shown on heating period, he closed air tight, the gas is shut off by ad vancing valve ,72,, the movable. part is the sketch. At the end of the plate 7 which is screwed tightly on to the part it. I

An exact regulation of both gas quantity and velocity and therefore of the .air quantity thereby drawn in is warranted by the chosen form of the conical valve 6. Ordinary valves, gate valves used up to now on burners are inadequate because they get easily choked up with dust and further they liberate relatively large sections when opened slightly, whereas the chosen form of and closed by when the cowper stove must tion and also the admission of any amount of gas to the cowper.

The inside of the mouthpiece f and the valve 7) can be cleaned from dust which deposits during work by pressing the valve 'on to its seat and turning it around several times.

Should an excess of air be required inside the burner 11 air.can be admitted bythe valvefb which can be made hollow, the admission being regulated by a slotted ring a. The gas enters under pressure the easing a and that by the transformation of pressure in velocity combustion air is drawn in. 'Naturally the opposite proceedings are 'possible,,viz. that air is blown in under pressure by the ring channel or the'hollow shaft (1 and thus the gas drawn in. The compressed air could also be introd ced in the casing a and its static energy changed by a corgesponding form of the burner into dynamic energy, by which then the gas would be d-rawn in either through the ring channel g or the hollow. valve.

. Having now particularly described and v ascertained the natur'eof oursaid invention and in vhat manner the same is to be perform wedeclare that what we claim is:

If A gas burner for hot blast stovesand ggher heating chambers having a casing with-in a fixed distance of the stove, atwyer for conducting the gas from the casing to the stove, said twyer being divided into sections,

a spindle mounted on the periphery of the twyer, a cover plate and one said section mounted on said spindle whereby the plate and section may be swung about the spindle and the stove supplied with gas or closed to the atmosphere.

2. A gas burner-for hot blast' stoves andv other heating chambers having a casing within a fixed distance of the stove, a twyer.

for conducting thegas from the casing to the stove, said twyer beingdivided into sections, a spindle mounted on the periphery of the twyer a cover plate and one said section mounted on said spindle whereby the plate and section may be swung about the spindle and the stove supplied with gas or c osed to the atmosphere, and a valve within the casing controlling the flow of gas as described.

3. A gas burner havinga perforated casing, a longitudinal shaft therein, a valve on said shaft to control the flow of gas, a twyer separable into movable parts, a cover plate fixed on one of said movable parts and hinged on the-periphery of said twyer and adapted to cut off the flow of gas through
