We AUGUST KUHNT and ROBERT DEISSLER, doing business under the firm
A. Kuhnt & R. Deissler, of 38, Alexander Str. Berlin C., Germany Engineers, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to gas-burners in which the gas and the admitted air are
heated and the object of our invention is firstly to heat intensely the gas to be
burned, secondly to free it from all impurities, thirdly to heat thoroughly the admitted
air and fourthly to conduct this hot air before and behind the gas-flame. Moreover
our invention covers a service applied to the chimney-tube having for its purpose to
regulate the intensity of the annular flame. The essential new features of our inven-
tion are
1.) The divided gas-chamber g, formed by the top-plate a provided with ribs and
the bottom-plate 6 provided with ribs r¹¹, the ribs bearing with indented edges
upon the opposite plates a b and letting pass the gas through these intendations.
2.) The intendations of the ribs decreasing from the inlet to the outlet of the
gas-chamber
9.
3.) The chimney-tube R enlarged above the gas chamber g and passing close to
the gas-admiting pipes D D¹.
4.) The ascending cross-plates w of the chimney-tube R.
5.) The flange u for spreading the flame.
6.) The regulating device fixed to the upper end of the chimney-tube R and
consisting of the semi-annular plates n n', which are connected with each other by
means of the right and left hand screw t.
On the annexed drawing fig. 1 is a vertical section, of the new gas-burner, fig. 2 a
horizontal section on the line xyz. Fig. 3 & 4 are top-views of the regulating
device and Fig. 5 shows parts of the annular ribs r².
The gas-chamber 9 consists of the top-plate a provided with annular ribs and
is srewed upon the bottom-plate 6 provided with ribs. The edges of the ribs r
bearing upon the opposite plates ba have indentations through which the gas is
passing. After unscrewing the plates a and b from each other the indentations of the
ribs can easily be cleaned.

The size of the indentations of the ribs decreases from the inlet to the outlet
of the gas-chamber g so as to throttle the gas passing through these indentations and
to heat it intensely. Besides this the gas leaves all impurities in the annular com-
partments formed by the ribs and enters thoroughly cleaned the burning pipes f.
An annular series of these burning pipes f is connected to the last compartment of
the gas-chamber g; as shown by fig. 2.
To the bottom-plate b of the gas-chamber is attached by means of the arms d the
globe-holder A, to which the glass-globe G is secured. The upper part of the globe-
holder A forms the chamber for admitting the airs to the flame. Between the
cylindrical casing H covering the burner and the globe-holder A is an annular space
for the admission of the air to the air-chamber L wherein the air is conducted to the
upper part of the burning-pipes f. A certain quantity of air passes through the
intervals between the burning-pipes f and descends to the flame, while the remainder
of the air is passing to the outer part of the flame. By this arrangement the air is
especially by means of the burning-pipes intensely heated before flowing to the
flame.
The centre of the apparatus is occupied by the chimney-tube R, to the lower end of
which is attached a spout v. The spout ends in a flange u serving to spread the
flame.
The regulating-device secured to the upper end of the chimney-tube R is constructed
as follows:
The semi-annular plates n n¹.supported by the chimney-tube R are connected by
means of the right and left hand screw t. By turning this screw t to the right or to
the left the plates and n¹ are approached to or removed from each other the aperture
of the chimney-piece and with it the intensity of the flame thus being increased or
decreased.
The ascending cross-plates w disposed within the chimney-tube R prevent dust from
falling through the chimney-tube, catch and collect the soot produced eventually by
the flame and regulate the ascension of the combustion-gases.
The gas is conveyed to the gas-chamber y through the gas-pipes D D¹ which are
connected with the gas-work and provided with a cut-off cock. The pipes D D¹
running down close to the chimney-tube R in order to heat the gas to be burned,
serve at the same time to suspend the burner. By fig. 6 is shown a vertical section,
by fig. 7 a horizontal section and by fig. 8 a detail view of a modified form of the
new burner having all new features of the latter but being far more economical in
cost of construction. The bottom-plate b, to which the perfectly flat top-
plate is fixed by means of the screws s, is provided with an annular rib the
screws are employed for releasing the plates a and from each other. The female
threads for the screws are disposed in the angle-pieces attached to the bottom-
plate b, whilst the top-plate a has the threads for the releasing-screws s³, passing
through holes of the angle-pieces which are attached to the bottom-plate b. In the
bottom of the inner compartment of the gas-chamber, divided by the rib r, are bored
the outlet holes of the gas. The air entering from above flows in this modified
construction before and behind the flame, as shown by the arrows.
Upon brackets secured to the bottom-plate b rests the glass globe C conducting the
air to the flame and equalizing in the well known manuer the radiation of the light.
The
gas is admitted to the burner by the pipe D.

Improvements in Gas Lamps.
We AUGUST KUHNT and ROBERT DEISSLER, doing business under the firm
A. Kuhnt & R. Deissler Engineers at 38 Alexander Strasse Berlin C. Germany.
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:
Our invention relates to gas-burners in which the gas and the admitted air are
heated, and the object of our invention is, firstly, to heat intensely the gas to he
burned, secondly to free it from all impurities, thirdly to heat thoroughly the admitted
air and fourthly to conduct this hot air before and behind the gas flame. Moreover
our invention covers a device applied to the chimney-tube having for its purpose to
regulate the intensity of the annular flame.
Reference being had to the drawings which were left with the provisional specifica-
tion, fig. 1 is a vertical section through y1 y2 (of fig. 2) of the new gas-burner,
fig. 21a horizontal section through a yz (of fig. 1). Fig. 3 & 4 are top-views of the
regulating device & Fig. 5 shows parts of the annular ribs ? ¹.
The essential new features of our invention are:
and
1) The divided gas chamber g formed by the top-plate a provided with ribs
the bottom-plate provided with ribs 11, the ribs bearing with indented edges
upon the opposite plates a band letting the gas pass through these serrations.
2) The serrations of the ribs decreasing from the inlet to the outlet of the gas-
chamber g.
3). The chimney-tube R enlarged above the gas-chamber g and passing close to the
gas-admitting pipe D.
4) The ascending cross-plates w of the chimney-tube R.
5) The flange u for spreading the flame.
6) The regulating device fixed to the upper end of the chimney-tube R and con-
sisting of the semi-annular plates nn (Fig. 3) which are connected to each other, by
means of the right and left hand screw t.
The gas-chamberg consists of the top-plate a provided with annular ribs rr, and is
screwed upon the bottom-plate b, which is also provided with ribs. The edges
of the ribs rr bearing upon the opposite plates b & a have serrations, through which
the gas passes. After unscrewing the plates a and b from each other, the serrations
of the ribs can easily be cleaned.
The size of the serrations of the ribs 1 decreases in size from the inlet to the
outlet of the gas-chamber g, so as to throttle the gas passing through these serrations,
and to heat it intensely. Besides this, the gas leaves all impurities in the annular
compartments formed by the ribs r¹ and enters the burner-pipes thoroughly
cleaned.
An annular series of these burner-pipes fare in connection with the last compart-
ment of the gas-chamber g, as shown by fig. 1.

page_text: To the bottom-plate 6 of the gas-chamber is attached, by means of the arms d,
the globe-holder A to which the glass-globe G is secured. The upper part of the
globe-holder A forms the chamber for admitting the air to the flame.
Between the cylindrical casing H covering the burner and the globe-holder A, is an
annular space for the admission of the air to the air-chamber L, where the air is
conducted to the upper part of the burner-pipes f. A certain quantity of air passes
through the intervals between the burner-pipes and descends to the flame, while the
remainder of the air passes to the outer part of the flame. By this arrangement the
air is, especially by means of the burner-pipes f intensely heated before flowing to
the flame.
The centre of the apparatus is occupied by the chimney-tube R, to the lower end
of which is attached a spout v. The spout v ends in a flange u serving to spread the
flame.
The regulating-device secured to the upper end of the chimney-tube R is con-
structed as follows:
The semi-annular plates n n¹ supported by the chimney-tube R, are connected to
each other by means of the right and left hand screw t. By turning this screw t to
the right or to the left, the plates n and n' are made to approach or to recede from each
other, and the aperture of the chimney-piece, and with it the intensity of the flame is
thus consequently increased or decreased.
The ascending cross-plates w disposed within the chimney-tube R prevent dust
from falling through the chimney-tube, and catch and collect the soot produced by the
flame, and regulate the ascension of the combustion-gases.
The gas is conveyed to the gas-chamber g through the gas-pipe D which is con-
nected to the gas-main, and provided with a cut-off cock C. The pipe D runs down
close to the chimney-tube R, in order to heat the gas to be burned, and serves at the
same time to suspend the burner in combination with the rod D¹.
In fig. 6 7 and 8 a modification of the above described arrangement is shown.
Fig. 6 shows a vertical section through line O P of Fig. 7.
Fig. 7 shows a horizontal section through line X Y Z of Fig. 6.
Fig. 8 shows a detail section of a part of the new modification.
This arrangement possesses all the new features of the former, but being cheaper in
cost of construction.
The following the difference of the modification, from the original form. The
bottom-plate, to which, the flat ring a is fixed, by means of the screws s, is provided
with an annular rib r; the screws s¹ are employed for moving the plates a and b
apart from each other. The female threads for the screws s are disposed in the angle-
pieces k attached to the bottom-plate b, whilst the top-plate a has the threads for the
releasing-screws sl passing through holes in the angle-pieces ¹, which are attached to
the bottom-plate b. In the bottom of the inner compartment of the gas-chamber,
divided by the rib 1, the outlet holes for the gas are bored. The air entering from
above, in this modified construction, flows before and behind the flame, as shown by
the arrows.
Upon brackets secured to the bottom-plate the glass-globe G rests conducting
the air to the flame, and equalizing in the well-known manner the radiation of the
light. The gas is admitted to the burner through the pipe D.
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 we
claim is:
1) In a gas lamp with preparatory heating of the gas and the combustion air, the
combination of the gas-chamber g with the combustion air-chamber L, plate A,
burner-tubes f, with spreading sheet m, cylinder with plate u, chimney R with
ascending cross-bars w w, a regulating-device t t at the top of the chimney, gas-tube D
and globe G, substantially as described and shown.
2) In a gas-lamp with preparatory heating of the gas and the combustion air, the
combination of the gas-chamber g being formed out of a top-plate a with ribs r

page_text: having saw like notches,, and a bottom-plate with ribs 1, having similar
