PROVISIONAL SPECIFICATION.
Improved Burner for Vapourised Liquid Fuel for Incandescence
Lighting or Heating Purposes.
-
I, WALTHER GLITSCH, of No. 1, Rennweg, Zürich, in the Republic of Switzer-
land, Engineer, do hereby declare the nature of this invention to be as follows:—
The object of the present invention is a burner for gas for lighting and
heating purposes produced from a liquid combustible by aid of a current of air.
This burner has two mixing nozzles, the one narrower and placed within the
wider one so that the openings of these nozzles are so calculated with regard to
the distributing cone of the combustible Howing out of the nozzle of the burner
that the said distributing cone can penetrate through them. The arrangement
is for the purpose of thoroughly mixing the gasified combustible with air.
In the accompanying drawing;
Figure 1 is an illustration in vertical section of one constructional modification
of a burner with the lighting device.
Figure 1 is a modification of a detail of Figure 1.
Figures 2 to 7 shew constructional modifications of heating bodies which can
be placed on the burner. The burner can be used substantially unchanged. either
for heating or for lighting purposes.
Over the nozzle a of a burner there is placed a mixing tube e provided. with
side slots for admitting air, which tube can supply air to the liquid'.com-
bustible escaping in the gaseous state out of the nozzle a of the burner. Above
the mixing tube & there is another mixing tube d, also with slide slots e, which is
for the purpose of causing a further admixture of air with the mixture of gas
and air entering therein so that the said mixture of gas and air may be rendered.
thoroughly effective.
The exit apertures of the mixing tubes correspond in their size to the distribu-
ting cone of the combustible escaping from the nozzle of the burner.

lu burners for lighting purposes, in order to gasify the liquid combustible
directly by means of the Buusen flame proceeding from the tubes, a perforated
cap'y is inserted over the mixing tubes in the 'burner cylinder f-surrounding the
latter. This cap y has a dome-shaped projection h having side perforations ¿
which direct the flame streaming out thereof against the burner cylinder f so
that the latter becomes heated. The cylinder conducts the heat downwards to the
pipe & supplying the liquid combustible,. so that the latter while passing through
k
the pipe is gasified by the heat, and can escape as vapour from the nozzle a of
the burner above the conducting tube k: The arrangement could also be só con
structed that the wall of the projection h (Figure 1) is extended beneath the per-
forated cap g. By this means the gases escaping out of the nozzle of the burner
would come partly inside and partly outside this extension.
The lamp is composed in the usual manner of an incandescent mantle 1, a
suspending wire or carrier, and the chimney gallery m. All the parts of the
lighting body are supported on a cover n which encloses the burner cylinder f.

page_text: The lower part of the socket n widens out into a bell o which fits over the openings
by which air enters to the mixing tubes.
The burner pipe is opened or closed by means of a screw valve p. In order to
use the burner for heating purposes it is necessary to remove the lamp from the
burner cylinder and to replace it by a suitable heater such as those illustrated
in Figures 2 to 7. The heater can be of any suitable shape as for instance
with a slit g and with side perforations for the flames (Figures 2 and 3, the
former on the section A-A of Figure 3), or it can also consist of a ring with
side holes for the flames, or of a star-shaped arrangement of pipes which are con-
nected centrally to a socket having a dome-shaped projection. (Figures 5 and 4,
the latter on the line B-B.of Figure 5.) A pipe with side perforations leading
from a socket can also be used as heater. (Figures 7 and 6, the latter on line C-C
of Figure 7.) All these heating devices have however a socket u which corre-
sponds to the socket of the lamp and can be placed on the burner cylinder f to
which the heaters are joined.
It is obvious that more than two mixing tubes can be made use of without
departing from the principle of the invention.
Improved Burner for Vapourised Liquid Fuel for Incandescence
Lighting or Heating Purposes.
I, WALTHER GLITSCH, of No. 1, Rennweg, Zürich, in the Republic of Switzer-
land, Engineer, 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 statement:-
--
The object of this invention is a burner for the purpose of the combustion of
admixtures of atmospheric air with gases resulting from the direct gasification
of liquid hydrocarbons, for use in lighting or heating apparatus. In carrying
this object into effect I construct the said burner in such a way that two concen-
tric sleeves, placed within each other, act so as to secure the intimate inter-
mixing of the gasified hydrocarbons with the atmospheric air and to this effect
the opening and section of the outer sleeve is so calculated and arranged as, to
correspond to the dimensions of the cone formed by the spreading gas resulting
from the gasification of the hydrocarbons, which emanates from the adjusting
aperture of the burner.
Figure 1 of the drawings filed with my Provisional Specification represents,
diagrammatically, the vertical section of such a burner, designed for lighting pur-
ровев:
-
Fig. 1 shews a modification of the combustion hood and dome.
Figures 2 to 7 represent modifications of the burner for use in conjunction
with heating or lighting appliances.
Above the adjusting aperture or jet a (Figure 1) is placed the mixing sleeve c
which is provided with lateral openings or slots for the adinission of air to the
gasified hydrocarbons emanating from the jet a. Over this first sleeve c a second
and larger sleeve d, provided with lateral openings or slots e, allows of the
admission of a further quantity of air which mingles with the admixture of gas

page_text: and air obtained by means of the sleeve c, and in this manner the admixture is
rendered very intimate.
The respective sections of the openings of the sleeves c and d are so calculated
as to correspond with the cone resulting from the spread of gas emanating from
the aperture a.
In the case of burners for lighting purposes, the upper part of the two sleeves c
and d is provided with a combustion hood with a sieve or gauze g placed inside the
cylinder which surrounds the distributing sleeves c, d. The sieve g is itself
provided in its centre with a small dome h the sides of which have small openings i
the object of which is to direct the flames emanating therefrom into the cylinder f,
the latter thus becoming heated. In this manner the heat of the cylinder f
travels in a downward direction and in its turn heats the liquid hydrocarbon
carrying tube & thus allowing the same to gasify immediately on its leaving the
aperture a.
The actual arrangements for the lighting appliance consist of the wellknown
parts and are composed of an incandescent mantle with the support and the
glass chimney w and the chimney gallery m. All these parts are fixed into
the sleeve n the lower edge o of which is turned outwardly and in the shape or
form of a bell, the object of which is to cover the distributing sleeves, which it
surrounds, and in this way the air which it is intended to use, for admixture
becomes itself heated before it is introduced into the gasified hydrocarbons.
The admission of the liquid hydrocarbons is controlled by the screw or needle-
adjuster by means of which the quantity of such liquid may be either regu-
lated or stopped at will, obtaining the day-flame if desired. by means of such
regulation.
When it is desired to use the burner for heating purposes it is necessary to
provide the upper part of the cylinder f with appropriate adjustments as shewn
in Figures 2 to 7. The burners of such heating appliances may be formed
by a longitudinal cut with lateral holes for the production of the flame
(Figures 2 and 3) the former of these representing a transverse vertical section of
the latter, across the line A-A; Figures 4 and 5 represent another arrangement
in which the central tube is provided with arms carrying the gaseous mixture
to the circular tube v which is provided with a number of holes or slots, (it being
understood that Figure 4 shews a vertical transverse section of Figure 5, across
the line B-B). A further mode of distribution is illustrated in Figures 6 and 7,
and this case; a straight tube or pipe, provided with holes or slots, as the case
may be, is mounted on the tube or sleeve u, (Figure 6 representing a vertical
transverse section of Figure 7, across the line C--C). In all cases above referred.
to the tube or sleeve is split longitudinally and is made to slip into the
upper end of the cylinder f above mentioned.
would further have it understood that more than two of the gas distri-
butors ed may be used and may be placed above one another.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. The construction and use of a burner for the purpose of direct gasification and
utilisation therein of liquid hydrocarbons, substantially as set forth and described
in the present specification.
2. In a burner, for the purpose of direct gasification and utilisa-
tion of the gases so produced therein, substantially as described and
