Burners or Gas Feed Nozzles therefor.
I, WILHELM STERN of Holzmarktstrasse No. 2 Berlin 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 statement :-
This invention relates to gas lamps in the which the gas and air are heated by
the flame, and it consists in certain improvements in the said lamp in the arrangement
and constitution of the gas and air feed passages and in the burner or nozzle to the
gas feed pipe.
Referring to the accompanying drawings
Fig. 1 is a vertical central section of the improved lamp.
Fig. 2 is a part of a horizontal section thereof as shown on line A B. Fig. 1.
Fig. 3 is an enlarged vertical central section of the burner or gas nozzle.
Fig. 4 is a horizontal section thereof on line C D Fig. 3.
E is the glass globe, F the flange by which the same is attached to the body G.
is the gas feed pipe terminating below in a burner or nozzle. The air feed
passages carry the air downward, around the burner and the flame passes outward,
over the deflecting ring H through the pipes d traversing the air feed chamber into
the chimney J.
There are two air feed or series of air feeds to the improved lamp, one air feed
being heated and passing from above downward around the burner, the other air feed
passing more or less down the wall of the globe E to the under side of the flame.
For the purpose of admitting air for these respective feeds to the lamp, two series of
holes c and g are formed around the edge or flange of the body G. Separating the
said series of holes one series from the other, is an annular wall a hollowed downwards
at z so as to form a trough as near as possible or convenient over the flame, the inner
edge of this annular wall is connected or continued to the upper edge of the wall K
which extends down to form the deflecting ring H. Within the annular wall and
passing through the extension or continuation of the latter which adjoins the wall K
are the pipes à extending upward through the roof of the body G into the chimney J.

page_text: To cause the air entering at the holes c to pass down into the trough of the annular
wall a, a ring b extends downward into said trough. Within the wall K is a per-
forated plate e and below the same, in convenient proximity to the burner is a sieve or
gauge, which may be corrugated, flat, or otherwise. The gas pipe / extending
centrally down the lamp terminates in a burner preferably of the following improved
construction.
The tube extends downward into a chamber in the burner, said chamber
narrowing above the lower end of said tube and extending upward at u along the
wall of the latter at a suitable height, in the upward extension of the chamber is a
series of perforations in the wall thereof communicating with an annular chamber »
the lower wall of which carries, near its outer edge a number of orifices ³ similar to
an Argand burner. The said annular chamber is situated above the chamber r²
aforesaid with its lower wall at a slight distance above the upper wall of the
latter chamber so as to leave an annular space into which the aforesaid orifices ³
open.
In construction the walls of the chamber are integral with the lower wall and the
interior wall of the chamber r. the latter being extended upward and screw threaded
inwardly for connection with the tube and outwardly for connection with a cap w
forming the outer wall of the chamber r.
It is convenient for obtaining a perfect combustion that means be supplied for
regulating the air feed. For this purpose above the flange having the holes cg is a
plate having correspondingly shaped holes c¹ and g¹ the same being however so
arranged that when turning or moving the plate h the closing for greater or less
amount of the holes c corresponds to the opening for an equivalent amount of the
holes g and vice versa. separate ring may be arranged however for each series
so that the regulation of each air feed may be independent of the other. The plate or
plates may be guided by set screws k passing through slots i therein.
h
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. In a lamp having annular flame and heated air feed, an annular troughed passage a
above the flanie for the purpose set forth.
2. In a lamp having annular flame and heated air feed the combination of an annular
troughed wall a above the flame with a ring b substantially as and for the purpose set
forth.
3. In a lamp having downward air feed above the flame a sieve or gauge plate f
corrugated or otherwise across said air feed passage for the purpose set forth.
4. In a lamp the combination of a series of holes g for cold air feed, a series of
holes c leading to heated air feed passages, and a plate or plates h having holes g¹ c¹
for relative or independent adjustment of said air feeds.
5. A burner nozzle comprising pipe l chamber with extension u annular
chamber perforations & air and annular space * substantially as illustrated and
described.
