Improvements in Globes and Chimneys for Incandescent Gas
Lighting, and for like use.
I, DANIEL MACFIE, of Milton House Works, Abbeyhill, in the City of
Edinburgh, Gas Engineer, do hereby declare the nature of this invention to be as
ollows:-
This invention has for its object to obviate or lessen the risk of breakage of the
chimneys and mantles used in incandescent gas lighting, by providing an improved
chimney either in combination with a globe, or independent thereof and adapted to
be suspended over the mantle from a globe of ordinary form instead of being fixed
upon a gallery or holder part of the burner.
When the chimney is formed in combination with a globe, the globe may be
of spherical or other form adapted to fit the gallery or other globe support on the
burner, but instead of terminating at the top in the opening through which the
ordinary chimney is passed it is there united with a cylindrical conical or other
funnel extending downwards centrally within the globe so as to surround the whole
or part of the length of the mantle or merely to depend over it and create the
necessary draft. The funnel may either be formed in the operation of producing
the globe or it may be cemented or similarly secured to it and it may also extend
upwards over the top part of the globe.
When the chimney is made separately it is formed with a flange or collar or
with projecting studs or arms around it by means of which it is suspended in the
orifice at the top of the globe so as to hang over the mantle. The supporting
flange or collar may be formed at or near the one end of the chimney in which
case the whole or greater part of the chimney will be suspended within the globe;
or the flange may be nearer the mid length so that part of the chimney protrudes
through the opening in the top of the globe. The flange may in some cases be
conveniently made by expanding in annular bulbous form the glass of which the
chimney is made, or it may assume any desired ornate form, and the upper end of
the chimney may be flared out or be otherwise formed to enhance the ornate effect
and to provide a convenient means for lifting it out of the globe.
When no globe is used the chimney formed as described may be suspended
over the mantle by means of a wire frame or other holder engaging the flange or
collar.

I. DANIEL MACFIE, of Milton House Works, Abbeyhill, in the City of
Edinburgh, Gas 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:-
This invention has for its object to obviate or lessen the risk of breakage of the
chimneys and mantles used in incandescent gas lighting, by providing an improved
chimney either in combination with a globe, or independent thereof and adapted to
be suspended over the mantle from a globe of ordinary form instead of being fixed
upon a gallery or holder part of the burner.
In the accompanying drawings,
Figures 1, 2 and 3 are vertical sectional views of a number of the various forms
of chimneys that may be used under my invention.
Figure 4 is a sectional elevation showing the chimney suspended in or supported
by the globe and
Figure 5 shows a suspension chimney adapted to be adjusted vertically in its
support.
When the chimney A is made separately from the globe as is shown by the
drawings it is formed with a flange or collar a, or with projecting studs or arms
around it, by means of which it is suspended in the orifice at the top of the
globe B, or in a plate or disc C carried by the globe, as indicated at Figure 4, so
as to hang over the mantle. The supporting flange or collar a may be formed at
or near the one end of the chimney A, in which case the whole or greater part of
the chimney will be suspended within the globe B; or the flange a may be nearer
the mid length so that part of the chimney protrudes through the opening in the
top of the globe. The flange may in some cases be conveniently made as indicated
at Figures 2 and 3 by expanding in annular bulbous form the glass of which the
chimney is made, or it may assume any desired ornate form, and the upper end A¹
of the chimney may be flared out or be otherwise formed to enhance the ornate
effect and to provide a couvenient means for lifting it out of the globe.
When no globe is used the chimney formed as described may be suspended over
the mantle by means of a wire frame or other holder engaging the flange or
collar.
As shown at Figure 4 a guide flange c is preferably formed on the supporting
disc C to maintain the chimney in its vertical position.
To permit of vertical adjustment of the chimney it may be made as shown at
Figure 5 of mica to which guide wires d are attached these wires passing through
guide orifices in the disc C which supports the chimney.
When the chimney is formed in combination with a globe, the globe may be of
spherical or other form adapted to fit the gallery or other globe support on the
burner, but instead of terminating at the top in the opening through which the
ordinary chimney is passed it is there united with a cylindrical conical or other
funnel extending downwards centrally within the globe so as to surround the whole
or part of the length of the mantle or merely to depend over it and create the
necessary draft. The funnel may either be formed in the operation of producing
the globe or it may be cemented or similarly secured to it and it
upwards over the top part of the globe.

tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A chimney for incandescent gas lighting and like use, constructed substantially
as hereinbefore described with reference to the annexed drawings, and adapted to
be suspended over the incandescent mantle.
2. The combination with a globe, of a chimney carried or supported thereby so
as to be suspended over the source of light substantially as described.
