SPECIFICATION forming part of Letters Patent No. 313,779, dated March 10, 1885.

No. 5.520; in France December 3, 1883, No. 158,939; in Belgium December 4, |883, No. 63,431, and in Austria-Hungary April 27,
1884, No. 10.259 and No. 18,515.
l'o crZZ whom it may concern:
Be it known that I, FREDERICK SIEMENs,
` a citizen of Saxony, residing at Dresden, in
the Empire of Germany, have invented a new and useful Improvement in Gas-Lamps, (for which I have obtained provisional protection in Great Britain, No. 5,520, dated November 26, 1883, and made applications in France and Belgium, dated,respectively, December 3, 1883, and December 4, 1883,) of which the following is a specification.
` The heat radiated from a gasflame depends to a great extent upon its luminosity, and the luminosity itself depends in great measure on the heat of the air and gas that combine in the act of combustion.
My invention relates to a eonstructin of gas-lamp by which I obtain so high a degree of luminosity that I can afford to shroud part of the flame by an appliance for heating the air and gas, this heating constituting the means by which so high a degree of luminosity is attained that the light given by the unshrouded part of the iiame is greater than would otherwise be obtained from the whole flame if it were destitute of the heating appliance.
I will describe the construction of the lamp which I adopt, referring to the accompanying drawings.
Figure l is'a vertical section, and Fig. l a sectional plan, of my lamp in its simple form; and Fig. 2 is a vertical section, and Fig. 2 a sectional plan,0f the lamp somewhat modified for larger sizes.
rIhe gas arriving by the pipe R enters a chamber, g, from which it rises by a number of small tubes, o', arranged in a circle. Surrounding t-hese tubes and extending some distance above them is a casing, Z, having at its lower part a number of holes and slits, tand t', for admission of air. The upper part ofthe casing Zpreferably terminates with a turnedin lip, a, and around the interior of the casing are a number of ribs, p, projecting inward. In the centerof the burner is a stem, s, made with projecting ribs p', and terminating with a conical head, n. The glass chimney .r is supported on several brackets, f, projecting from the easing Z. The flames of the gas issuing from the tubes r radiate heat to the casingZ purposes.
and to the stem s, the ribs p and p' of which expose extended surfaces, and the air entering by the holes and slits t and t becomes highly heated as it ascends in contact with these heated surfaces. The gas is alsoheated by the heat conducted down the casing, stem, and tubes, and thus afiame ot'great intensity is produced, with illuminating-power so great that the part of it which appears above the casing gives greater light than the whole darne would give if no part of it were shrouded by a casing arranged to heat the air-supply. The lip a of the casing and the head n of the stem by directing the ascending current of heated air against the outside and inside of the cylindrical flame cause great intensity of light above the casing.
I am aware that annular caps of conical or convex form have been heretofore so constructed as to rise a little higher than the hub ofthe burner for the purpose of deecting air upon the flame or steadying it.
I am also aware that in the German Letters Patent No. 18,884, of the year 1882 heretofore granted to me, a burner is described in which some distance above the top of an outer ring of tubes; but it is to be remembered that the flame from the latter is entirely inclosed by the casing and does not operate as a part of the illuminating-dames of thelamp, as in my present invention, but serves entirely for heating When the lamp is made of small size, where the area for passage of air is limited, the ribs p p may be dispensed with. For lamps of larger size the construction may be modified, as shown in Figs. 2 and 2*. In this case the central'stcm, s, is made tubular, with slits t2 at its lower part for admission of air t0 its interior and with its upper lip, n, curved outward. Within it is a gas-tube, r', the ame from which heating the stem increases its power of heating the air passing upward between it and the casing Z.
In the drawings the gas entering the chamg5 be arranged in such a manner as to form an Ico the casing of one of several sets of tubes reaches v ellipse or other suitable ligure, and that instead of using the tubes r to conduct the gas to the point of combustion any other suitable known devices may be used-as, for instance, an annular or Argand burner having holes arranged therein a certain distance apart for the escape of the gas.
Having thus described the nature of my invention and the best means I know of carrying it out in practice, I claiml.'. In a gas-lamp, the combination ola number of gas-jets with a relatively high central tending above them, and a chamber located above the gastubes and within the cylindrical casing in which the flames ot' the gas issuing from the jets are partially shrouded and the heat thereof is radiated to the casing.
3. The combination of the chamber communicating with the gas-pipes from which rise a number of small tubes or jets, a perforated casing surrounding the tubes and extending some distance above them, and a chamber located above the gas-tubes and within the cylindrical casing in which the llame ofthe gas issuing from thejets is partially shrouded and radiated to the casing.
4. ln agas'I-lamp, the combination ofa number of gas-jets, a relatively high stein terminating with a conical head, a relatively high cylindrical casing, and a chamberlocated above the gas-jets and between the stem and the casing in which the flame of the gas issuing from the jets is shrouded and radiated to the casing.
5. In a gas-lamp, the combination ofa number of gas-jets, a relatively high stem terminating with a conical head, a relatively high cylindrical casing terminating at its upper part with a turned-in lip and having in its lower part a number of slits, and a chamber located above the gas-jets and between the stem and the casing in which the flame of the gas issuing from the jets is shrouded and radi` ated to the casing.
6. In a gas-burner in which the gas issues in a series of small jets, a metal casinginclosVv ing thelower part of the llame which serves to take up the heat of the flame and impart it to the gas and air supply, in combination with a chamber in which the flame of the gas issu ing from the jets is shrouded.
In testimony whereof [have signed my name to this specification in the presence of two subscribing witnesses this 8th day of January, A. D; 1884.
