IMPROVEMENTS IN REGENERATING GAS LAMPS
Year: 1888

page_text: We JOHANN WILHELM KÖRBER, of Düsseldorf in the German Empire, Engineer,
and WILHELM STEUTH also of Düsseldorf in the German Empire, Engineer
do hereby declare the nature of said invention for "IMPROVEMENTS IN REGENERATING
GAS LAMPS " and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The improvements of this invention rolate chiefly to a bottom supply of air by an
arrangement of tubes; to the peculiar construction of the regenerator; and to the
arrangement for enabling the ignition of the lamp to be effected from the outside of
the glass shade.
Referring to the accompanying drawings
--
Fig. 1 is a longitudinal section of a regenerating gas lamp in accordance with this
invention. Figs. 2. and 3. respectively a vertical section of the burner with bottom
prolongation for air supply and a horizontal section thereof. Figs. 4 and 5
respectively a vertical section of the regenerator and a horizontal section of the same
through line A B.
The regenerating gas lamp further consists of parts that are not novel, namely, the
gas supply tube a, stop cock b glass shade H, shade, ring h, discharge tube K with
encircling air tube k and air chamber J.
The gas is supplied through tube a to annular Argand burner o which is in
communication with a bottom part formed by tubes D arranged in the form of a ring

page_text: for the supply of air from underneath. They are in communication at bottom with
the casing L and at top with air chamber N the latter having inside a projecting edge i
and also a strainer n placed within it for the purpose of distributing and balancing
the supply of air flowing out' at in the direction of the arrows against the lower
surface of the flame. The casing L is provided laterally with a number of
perforations serving to conduct air to the inner surface of the glass shade. Over the
casing La deflecting disc m is slid on to the tubes D) and serves to deflect the air
flowing in through the perforations from its direct course to the burner and to direct
it past the inner surface of the glass shade whereby this latter is kept somewhat cool
and unsteadiness of the flame prevented. The glass shade is fixed on casing L by
means of pressure ring S.
The greater portion of the air necessary for the thorough combustion of the gas
and for producing an intense white flame is supplied through regenerator C to the
upper surface of the flame. This regenerator is distinguished from all others hitherto
in use by its peculiar construction by which a much higher temperature is communicated
to the supplied air than in the case of other gas lamp regenerators. It has both
inside and outside the form of an inverted truncated cone with double wall or periphery
forming an annular air.passage R and collecting chamber V for the escaping products
of combustion. Across the annular air passage R are fixed a number of nozzles
zigzag underneath each other through which the products of combustion must pass in
their course towards the discharge tube, and heat the surface of the nozzles as well as
that of the truncated cone to a red heat.
The conical form of the regenerator and the direction of the nozzles thereby
necessarily brought about, have for effect that the products of combustion impinge
against its surface in a niore or less normal direction thus communicating to it a
greater heat than in the case of cylindrical regenerators. The air requisite for intense
combustion takes its course to the flame in the direction shewn by arrows w, but cannot
arrive there in a direct line as it must impinge against and around the surface of the
zigzag placed nozzles in a winding direction, and over a relatively large heating
surface thus attaining a far higher temperature than when it has a direct course.
As compared with the regenerating gas lamps hitherto known in which ignition has
to be effected immediately at the burner in a troublesome way, the ignition in the case
of this invention is effected from outside the glass shade in the simplest manner by
means of the following arrangement: From the top of the stop cock b a smaller gas tube
branches off, leading through the space between the discharge tube K and air tube k
downwards to the small stop cock f, on a lateral projection on which latter is mounted
a small perforated tube g in which close to the stop cock f a larger perforation y is
provided for effecting the ignition.
The principal stop cock being shut, the cock f is opened and the outflowing gas
ignited at y. The burning flame springs from one perforation in the sinall perforated
tube g to another until it reaches the mouth of this latter where an elongated thin
flame forms in the direction of the burner o. The cock b is then opened, the gas
flowing to the burner o is ignited, and the cock then at once shut.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that we are
aware of Fourness's specifications numbered 732188 and 1255487 & we wish it to be
understoood that we lay no claim to anything described and claimed therein, but what
we claim is:
1. In regenerating gas lamps, the combination of a series of air tubes D arranged
in the form with the upper air chamber N, the strainer n placed therein, the laterally
perforated casing L and the deflecting disc m for the purpose of conducting the air to
and equally distributing the same over the lower surface of the flame, substantially as
described and shewn.
2. In regenerating gas lamps the construction of a regenerator in the form of a
double walled truncated cone the annular space R of which is crossed by nozzles or

page_text: perforations set out zigzag and having a collecting chamber V for the escaping products
of combustion substantially as described and shewn.
3. In regenerating gas lamps the arrangement for enabling ignition to be effected
from the outside of the glass shade or cover without removing or opening this latter
consisting of the gas supply tube e stop cock ƒ, and the perforated tube g in connection
therewith substantially as described and shewn.
