Specification of Letters Patent.
Patented Oct. 10, 1905.
Application filed October 27. 1903. Serial No 178,303.
To all whom it may concern:
Be it known that we, HEINRICH WILHELM HELLMANN, engineer, residing at 7 Zinzendorfstrasse, and OSKAR ARENDT, civil engineer, residing at 216 Friedrichstrasse, in Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Inverted Gas-Li ht Incandescent Lamps; and we do hereiy declare the nature of our invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement.
Our present invention is relative to a gas incandescent-light lamp burning downward, being characterized by a plate with outlets for the rising hot combustion-gases being arranged immediately above the glass bulb and the hot gases being sucked out of the bulb with a draft analogous to that of a chimney.
By the aid of the following description, as well as of the annexed diagram, our invention has been fully exposed.
The drawing shows a longitudinal section of the invention.
In the inverted gas-lamp shown in the figure in longitudinal section a screening-off or deflecting plate 14 is arranged upon the burner-head 7, which is preferably made of fire proof heat non conducting material. The plate 14: may, if desired, be formed in one piece with the burner-head 7, but could also e arranged on another place of the mixing-tube. The transparent protecting-bulb 82, which surrounds the incandescent body '11, is suspended immediately below the screening-off and deflecting plate 14 and from a three or more armed supporting-yoke 33, fastened to the mixing-tube 1. Upon the outer rim of the plate 14 we provide outwardly-opening inclined perforations and tubes 15, the number of which may be different, according to their inner diameter, and which may be arranged in any suitable manner. The hot gases of combustion ascending from the mouth of the burner and from the incandescent body are deflected away laterally through the said tubes. The defleeting-surface of the plate 14 is decreased by the said inclined tubes, so as to revent any harmful stagnation of the ascen ing hot gases of combustion, and we thereby also avoid heating the plate 14 to an unduly high temperature. The chimney-draft created by the tube extensions produces the flow to the mouth of the burner of a powerful supply of air through the lower openings of the lamp-shade, the draft causing the ascension of the hot gases of combustion in the interior of the shade 32, and by this means the illuminating power of the incandescent body 11 is increased. By means of caps, stoppers, or covers 34 one or the other of the exit-openings may be covered or may be partially closed.
Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is 1. In an incandescent gas-lamp the combination of a mixing and burner tube, a burner-head at the lower end of the burnertube, an incandescent body round the burnerhead, a transparent protective bulb surrounding the' incandescent body, means for fastening the said bulb on the mixing-tube a deflecting-plate immediately above the transarent protective bulb this plate having a arger diameter, than the outlet-opening of the said protective -bulb plate outwardlyopening tube extensions above the perforations of the deflecting-plate substantially as and for the purpose described.
2. In an incandescent gas-lamp the combination of a mixing and burner tube, a burner-head at the lower end of the burnertube, an incandescent body round the burnerhead, a transparent protective bulb surrounding the incandescent body, means for fastening the said bulb on the mixing-tube a deflecting-plate immediately above the transparent protective bulb this plate having a larger diameter, than the outlet-opening of the said. protective-bulb plate outwardly opening tube extensions above the perforations of the deflecting-plate covers for the tube extensions substantially as and for the purpose described.
In witness whereof we have hereunto set our hands in the presence of two witnesses.
