An Improved Chimney for Lighting Purposes.
Year: 1897

page_text: I, ENRICO LAZZAR, of 15 Chiadino Via Pieta, Triest, in the Empire of Austria,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The present invention relates to a double-draft chimney for all kinds of light-
ing, which consists essentially of a chimney to be put on a burner or the gallery of the
same and of a loose or second chimney to be inserted and which does not reach the
gallery of the burner but will rest on an inner shoulder of the first chimney, so
that the real chimney in its lower part is formed of the exterior chimney and in
its continuation upwards of the interior chimney. The air between or circulating
between the chimnies keeps the heat from the exterior or outer cylinder so that
this will be much cooler and will not be liable to crack so easily. This outer
chimney protects on its part the inner chimney against draft or unintentional
bespatter with moisture and by that has the advantage that, should the inner
chimney crack, it will be hied in its original position by the outer chimney so that
the parts cannot fall down.
In order to make possible a circulation of the air between the two chimnies for
the purpose of cooling the same openings may be provided in the outer chimney
near the shoulder which will allow fresh air to enter the space between the
chimnies. At the place where these openings occur the chimney may be provided
with a bulge or may be made quite even with the other part of the chimney surface.

An Improved Chimney for Lighting Purposes.
I, ENRICO LAZZAR, of 15 Chiadino via Pieta, Triest, in the Empire of Austria-
Hungary, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The present invention relates to a double-draft chimney for all kinds of light-
ing, which consists essentially of a chimney to be put on a burner or the gallery of the
same and of a loose or second chimney to be inserted, and which does not reach the
gallery of the burner but will rest on an inner shoulder of the first chimney, so
that the real chimney in its lower part is formed of the exterior chimney and in
its continuation upwards of the interior chimney.

page_text: The air between, or circulating between, the chimneys keeps the heat from the
exterio or outer cylinder so that this will be much cooler and will not be liable
to crack so easily. This outer chimney protects on its part the inner chimney against
draft or unintentional bespatter with moisture and by that has the advantage that,
should the inner chimney crack, it will be held in its original position by the
outer chimney so that the parts cannot fall down.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section.
Fig. 2, a horizontal section the line of such a double draft chimney.
Fig. 3, is an alternate pattern ith air holes f at the bottom of the inside
chimney.
The same consists, as shown, of the chimney a and the chimney b arranged
therein, and which does not reach completely down but ends on a shoulder a² of
the outer chimney and rests on this shoulder. By this arrangement the
chimney in its lower part is formed of the contracted part a¹ of the chimney a
proper
and in its upper part of the inserted chimney. Owing to the fact that the latter
rests freely on the shoulder a² it can easily be taken out to be cleaned or exchanged
or reinserted, as it has a guide in the outer chimney a and therefore by using it
for an incandescence burner this cannot become injured.
In order to make possible a circulation of the air between the two chimneys a
and b for the purpose of cooling the same, openings d d may be provided in the
outer chimney a near the shoulder a², which will allow fresh air to enter the space
between the chimneys. At the place where these openings occur the chimney a
may be provided with a bulge as in Figs. 1, and 2, or may be made quite even with
the other part of the chimney surface as in Fig. 2, the inner chimney being pro-
vided with air holes f as it rests on the shoulder a².
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. In a chimney for lighting purposes, the combination of the various parts
substantially as above described in this specification and illustrated in the accom-
panying drawing.
2. In a chimney for lighting purposes, the combination of the various parts sub-
stantially as above described in this specification for the purpose specified.
3. In a chimney for lighting purposes, the combination of a double draft
chimney and air holes, substantially as herein described and according to the
accompanying drawing.
4. In a chimney for lighting purposes, the combination of a shoulder, bulge 4
and openings in the outer chimney, and the loose inserted chimney, substantially
as described.
5. In a chimney for lighting purposes, the combination of a plain or even outer
chimney a shoulder a contracted part a¹ and the inner chimney with air holes f,
substantially as herein described and according to Fig. 3, of the accompanying 4
drawing.
