Improvements in or connected with Incandescent Gas Light
Burners.
1, AUGUST NAGEL of 62 Langestrasse, Baden-Baden in the Empire of Germany,
Merchant do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following stateinent :-
This invention, which is shown in the accompanying drawings in vertical central
section, has for its object an incandescent burner, the construction of which differs
from those forms of construction already known, in that the lighting effect of the
incandescent body and the saving of gas over the ordinary incandescent burners is
essentially increased by the introduction or employment of air under pressure.
The gas is supplied in the ordinary manner from below by means of a pipe a, rises
upwards in the vertical pipe b, and on being lighted as it leaves the vertical pipe
causes the mantle o to become incandescent. The air under pressure, produced by
means of a water motor, fan, electrical power, or in other suitable manner,
to the burner through a thin lead, iron or brass pipe, which runs along the gas pipe.
is supplied
Close to the place where it enters the burner, the gas supply and also the supply of air
under pressure may be regulated by means of a common tap, or by two separate taps
connected to work together. Behind this tap, the pipe d for the air under pressure is
arranged at the side as high as the burner and turned towards the same.

process of combustion will not proceed noiselessly. At the top of the pipe and carried
up higher are two fine wire networks or sieves, one of which flies directly under the
surface of the burner cap or head, whilst the other g lies about one centimetre lower
down. These produce a steady light and a noiseless combustion.
Such a burner does not require a chimney or cylinder. The mantle is suspended on
a wire or arm of pure nickel, which may be held in a manner suitable to the length
of the mantle by means of a screw i at the side.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improvement in or connected with incandescent gas light burners, consisting
n supplying air under pressure by means of a special supply pipe to the current of
gas, and in providing a sufficiently lengthy chamber or space for the mixing of the
gas and air under pressure, whereby the lighting effect of the incandescent body and
he saving of gas, as compared with ordinary incandescent burners, is considerably
ncreased.
2. In an incandescent gas light burner such as described, the arrangement of a ·
econd wire network (g) at about one centimetre below the network (f) which forms
he cover of the pipe, with the object of producing a steady light and a noiseless
ombustion, substantially as hereinbefore set forth.
