Heretofore in such lamps the gas supply pipe terminates in a chamber whence
small tubes deliver the gas as jets, or pipes feed the gas to the burner or jet proper.
In the improved lamp the gas is supplied direct to the chamber which forms the body
of the jet said chamber being broad above and narrow below, terminating below in an
annular jei from which the gas issues to the flame.
In a cylindrical chamber terminating below in an inverted truncated hollow cone,
is contrived the gas chamber or jet body consisting of two concentric truncated
conical parts, concentric also with the conical extension of the cylinder aforesaid and
terminating below substantially level with the rim thereof-The angle of incline of
the inner conical part is greater than that of the outer conical part, and the angle of
the latter is greater than that of the conical extension of the cylinder-The space
between the inner and outer conical parts of the jet body, is closed above, and is
supplied with gas through suitable pipes-The lower rims of the said parts form
between them the jet proper whence the gas issues-Centrally within the cylinder
and inner conical wall of the jet body, passes the chimney the lower part of which is
formed of incombustible material, the lower edge being spread radially outward to
form a distributing ring for the flame-The jet body and the chimney are connected
to the cylinder casing aforesaid in such a manner as not to interfere with the passag

on each side of the jet body and thence to the flame, which latter passes outwardly
and downwards over the distributing ring the products of combustion ascending
through the central chimney.
The glass globe is secured against the flange formed at the base of the cylinder
there being in this flange a groove containing a ring of asbestos or the like against
which the rim of the globe is held by suitable hooks.
To equalize the distribution of gas in the jet body, we provide one wall of the body
with an annular flange extending towards the opposite wall of the body but not in
contact therewith.

page_text: We JULIUS VON QUAGLIO and CHRISTIAN WESTPHAL both of 78 Friedrich Strasse
Berlin in the Empire of Germany, Manufacturers 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 principally to such lamps or burners for gas as have a
downwardly directed flame witli central chimney and it consists in an improved gas
jet applicable principally to such lamps or burners and generally to the arrangement
and combination of parts of the lamp.
Heretoforo in burners of this description the gas supply pipe terminates in a
chamber whence small tubes deliver the gas as jets or whence the pipes feed the gas
to the burner or jet proper.
In the improved lamp the gas is supplied direct to the
chamber which forms the body of the jet said chamber being broad near the gas inlet
and narrow towards the outlet terminating in an annular orifice or circular jet from
which the gas issues to the flame.
Suitable distributors as hereinafter described may be arranged in this improved
burner.
The improved lamp is constructed as follows: In a cylindrical chamber terminating
below in an inverted truncated hollow cone is contrived the gas chamber or burner
body consisting of two inverted concentric truncated conical walls or parts concentric
also with the conical extension or termination of the cylindrical chamber aforesaid
and terminating below substantially level with or slightly above the lower rim thereof.
The angle of incline of the inner conical part or wall is greater than that of the outer
conical part or wall of the burner body and the angle of the latter is greater than that
of the conical extension of the cylindrical chamber. The space between the inner
and outer conical parts or walls of the burner body is closed above and is supplied
with gas through a suitable pipe or pipes. The space between the lower rims of the
said parts or walls forms the jet or burner proper whence the gas issues. Centrally
within the cylindrical chamber and inner conical wall of the burner body, passes the
chimney the lower part of which is formed of refractory material the lower edge
being spread radially outward to form a ring for the purpose of distributing or
spreading the flame. The lower portion may be detachable and fastened by a bayonet
or other fastening to the lower end of the upper portion of the chimney. The burner
body and the chimney are connected to the cylindrical chamber aforesaid in such a
manner as not to interfore with the entering of air into the upper end or other part
of the cylinder and its passage therein to the conical spaces on each side of the jet
body and thence to the flame, which latter passes outwardly over the distributing
ring and under the latter to the central chimney through which the products of
combustion ascend. Reference being made to the accompanying drawings Figs. 1

page_text: and 2 show respectively in vertical central section two forms of the improved
lamp.
In Fig. 1A is the cylindrical casing of the lamp enclosing and forming the
air chamber and narrowed below in the form of a hollow inverted truncated cone.
In the lower portion of the casing is placed the improved burner consisting of the
outer inverted truncated conical wall B connected to the outer cylinder A at
intervals by stays and projecting inwardly at its upper edge to form a flange
which carries and forms a secure joint with the second part of the burner, namely
the inverted truncated hollow conical part C of greater steepness than the part B
and extending downward so that its lower edge is level with the lower edge of
the latter and at a short distance therefrom to form with it an annular jet for the
issue of the gas. The gas pipe a may either pass laterally as on the left of Fig. 1
or vertically downward as shown on the right of said Figure into the upper portion
of the space enclosed between the parts B and G. Down the centre of the cylindrical
chamber extends the chimney D preferably made in one part with the flange k the
rim of which is fastened inside the upper edge of the cylinder A whereby the
chimney is supported and a cover is formed to the cylinder by the flange. The latter
may or may not be perforated for admission of air into the cylinder A. The
chimney D extending downward to near the upper edge of the burner body
terminates in and is continued downward by the tube E of refractory or heat with-
standing material such as brass, stone or china-ware which may be connected therefo
by a bayonet fastening. The tube F extends downward to a suitable distance below
the lower rim of the burner and is then flanged outward to form a flame distributor h.
A flange m is formed on the lower edge of the cylindrical portion of the casing A
a recess being left in the under edge thereof to receive a ringe of asbestos or other
suitable material, the rim of the globe G is held firmly against this ring by springs or
hooks as d, one or more of which may carry a lever for loosening them and releasing
the globe when desired.
It will be seen that the air entering into the chamber A passes downward on each side
of the annular burner and issues to the flame F the latter passing outward and downward
under the ring into the chimney and flue H. The general construction differs
slightly in Fig. 2. Here the cylindrical portion A does not form the exterior of the
lamp but extends upward only to a certain distance above the burner body, it is
covered by a dome / which may be made in one part with the flange and chimney D,
the said dome extends downward outside the cylinder A to near the flange thereon
where it is connected to the said cylinder by wehst so that spaces are left for entrance
of air at the base of the dome. The globe G is, in this figure, supported by a ring H
hinged at p to the flange of the body A and carrying at the opposite side a rotary
hook adapted to fasten over the rim of said flange. Small passages s are arranged
in the flange to permit air currents to pass down on the inner side of the globe G
whereby the latter is kept cool. > is a cushion or wad of any suitable material.
To equalize pressure of gas in a burner of the kind described, flanges or plates may
be so placed therein as substantially to divide the annular body into two annular
portions with passages connecting them so that the gas is more or less restrained in
its passage from that annular space in which it first arrives from the pipe a into that
annular space from which it issues to the flame.
Several forms of baile plate or flange are shown in the drawings hereunto annexed.
Thus on the left of Fig. 1 is shown a flange e integral with the inner wall of the
part B and extending towards the opposite wall but not entirely in contact therewith.
On the right of Fig. 1 the space is shown entirely free. On the left of Fig. 2 another
modification is shown being a vertical plate e fastened at its upper edge between the
parts B and C and abutting at its lower edge against a flange on the body B being
held thereto by offseis o on the body C, perforations m permit of the passage of gas
from one annular space to the other. Again on the right of Fig. 2 is shown another
modification in which the plate e supported below as before indicated has an upper
serrated edge abutting against the wall so as to leave spaces n for passage of
the gas.
