UNITED STATES PATENT OFFICE.
FRITZ STELLVAG, OF BERLIN, GERMANY.
REGENERATIVE GAS-BURN ER.
SPECIFICATION forming part of Letters Patent No. 435,670, dated September 2, 1890.
Application filed October 9, 1889.
To all whom it may concern:
Be it known that I, FRITZ STELLWAG, a Subject of the King of Prussia, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Regenerative Gas-Burners, of which the following; is a specification, reference being had therein to the accompanying drawings.
Figures 1 and 2 of the accompanying two sheets of drawings represent gas-lamps of my improved system in four modified forms, so arranged that the middle line in Fig. 1 separates two different forms and that the middle line in Fig. 2 separates, also, two different forms, all four being shown in a vertical section. The flame f, burning downward from the mouth of theburner c, burns into the central chi mneyll, the lower end of which is armed with a mouth-piece F, made of fire-proof material. The air, as indicated in the drawings by arrows, passes successively through three chambers A, B, and O, in order to be heated, and then feeds the flame f, after having circulated around the ring-shaped burner D E. The gas is admitted through pipe 1 and flows directly into the tubular part a of the burner, which communicates with the outside by an annular opening 1) c. The products of combustion are led off through the chimney H in upward direction.
The new features of my improvements are the burner, especially constructed to prevent the decomposition of the gas, and the arrangement and disposition of the air-heatin g chambers. The burner is composed of two conical parts D and E, fitted into one another. The gas arriving through the pipe 1 flows directly (without passing through any intermediate reservoir) into the burner, where it finds at a an annular widened space,which it has to fill. Thence it passes into an annular space 1), divided by a certain number of radially-placed partitions b into the like number of cells or flues communicating at their outer ends with the space a and inside with a free annular space or gasdischarge opening I) 0. These partitions are used to steady the inner part E of the burner in a true central position, and their number may vary from at least three to any number above three. Finally the gas flows into the free annular space I) c and es- Sarial No. 326,524. (No model.)
capes through the mouth 0 of the burner. The area of the annular free space at b is larger than the cross-section of pipe 1, and as the annular space is still widening toward the outlet or the burners mouth, so that the area of its free annular space at c is larger than that at Z), it results that the gas on its passage to the flame finds everywhere more room in proportion to its increased volume, owing to the constantly-increasing heat. Thus a constant velocity of the flow of gas is obtained and any injurious pressure is avoided. The passage forthe gas must be comparatively short, so as to avoid an overheating in the burner, which would eliminate carbon from the gas and occasion a smoky flame and a filling up of the burner with soot. A very quiet flame and even burning maybe obtained by this means.
The arrangement of the chambers for heating .the air A, B, and O has for its object, first, to thoroughly make use of the heat produced by the lamp; second, to exclude cold air from the lower partof the chimney and from the flame, (as often produced in closed rooms by the slamming of doors,) thus avoiding smoking of the flame. V here only one or two chambers for heating the air are employed, the same result may be approximately attained by reducing the size of the apertures through which the air enters into the chambers.
Fig.2 represents at each side of the middle line in vertical section a modified form of a gas-lamp of my system. The flame is burning from inside to outside around a deflecting-disk a, The products of combustion ascend in the annular chamber 13 and escape through chimney K. The air enters between the bottom plateD of the lamp and the lower rim of shell E into the chamber A. One part is going up and passes through the fines F into the inner chamber G, where it takes a downward direction to feed the flame. The other part of the air is going down through openings 9, passing around the deflector 0 into the glass globe J, where it ascends to the lower surface of the flame. The burner is constructed after the same principle as the burner above described. The area of the passage for the gas becomes wider and wider toward the burners mouth d in accordance with the increase of temperature. The two conical parts G and H are fitted together by emerygrinding, H being screwed at K into the top plate of the heating-chamber. The gas is admitted through pipe 1,which is bent so as to be outside of the chimney and to avoid a superheating of the gas. A small deflector h is fixed below the burner, as shown.
What I claim as my invention, and desire IO to secure by Letters Patent, is-
In gas-lamps fed by heated air, a gas-burner having an annular enlarged chamber a and in presence of two Witnesses.

TH. LoRENs, GEO. H. MURPHY.
