PROVISIONAL SPECIFICATION.
A New or Improved Combined Chimney and Shade for
"Gas-
burners," Lamps, and the like, upon which Advertisements may
be Displayed.
I, ERNEST BÖHM, of 5, Boxworth Grove, Richmond Road, Barnsbury, N., Glass
Manufacturer and Electrician, do hereby declare the nature of this invention
to be as follows:
"
"
"
This invention relates to new or improved combined chimneys and shades for
gas-burners" lamps and the like; the object being to combine with the chimney
of so called gas lights" gas jets' gas-burners or "lamp-burners" or
lamps for burning oils, fats, or other materials which when ignited or subjected
to the process of combustion by ignition or burning will emit light for illuminating
purposes.
66
The chimney formed to any required shape and to fit the holder or "gallery" is
to be made with a capping or bonnet" above the usual opening of said chimney
within which the combustion of the illuminant takes place and the emission of
light results, said capping or bonnet extends beyond the sides of the chimney and
over the combustion space to form a brim" extending out from the chimney and
arched over the area of illumination above the "burner." Piercings or holes are
provided around the said capping or bonnet to allow of an induced current of air
to the combustion space within the chimney aforesaid.
66
The chimney will be united with the cap or bonnet by the brim or underlying
Hange by ordinary process of glass blowing or the like or as may be found ex-
pedient.
"
"
The chimney may be of crystal glass decorated or not or of tinted or colored glass,
the arch of the capping or bonnet may be of opal glass, colored or tinted glass
or frosted," silvered, or gilded glass to serve as a reflector and throw down the
rays of light and the under side of the cap or bonnet that is "the brim".
may be
of crystal or clear glass, tinted or not, and have letters, words, devices for advertise-
ments, or ornamentation and burnt in or otherwise applied, as may be found
desirable.

page_text: 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 the manufacture of combined chimneys and shades
for gas-burners, lamps, and the like, the object being to unite with the chimney a
shade or bonnet which will serve as a reflector of light, and will carry, and will
display to view, any device suitable for advertising purposes.
The chimney, formed to any required shape to fit the holder or "gallery" of the
lamp or burner, I make in one with a capping or "bonnet" above the usual open-
ing of said chimney, which bonnet extends beyond the sides of the chimney,
forming a "brim," and having an arched crown extending over the area of illumina-
tion above the burner. A ring of pierced holes is made in the periphery of the
bonnet, to allow of the passage outwards of the gases of combustion from the
chimney.
In the accompanying drawing,
Fig. 1 shows, in elevation, and
Fig. 2. in inverted plan view, a chimney of my improved construction, suitable
for an incandescent gas burner.
Fig. 3 shows, in elevation, a chimney and reflector shade for an oil lamp of
the Veritas" type and
Fig. 4 is a similar view of a chimney and reflector shade for a lamp of the
Cosmos kind.
In all these figures, A is the chimney, and B the hollow shade or bonnet, formed
of blown glass, at one operation, in the manner commonly practised in the glass
trade. 6 is the brim intended to receive a device, which may be applied in any
approved manner, and is the crown of the bonnet of a shade, which may be made
of opal glass, or may form a metallic reflector by the burning into the glass a
metallic surface whether of gold or silver. 62 is a ring of holes, through which
the gases of combustion from the burner or lamp will pass out to the atmosphere.
I may here remark that the chimney may be of crystal glass, decorated or not,
or of tinted or colored glass; the arch of the capping or "bonnet"
may, according
to taste, be either of opal glass, colored or tinted glass, or "frosted" silvered, or
gilded glass, to serve as a reflector, and throw down the rays of light, and the
underside of the cap or bonnet, that is, the "brim," may be of crystal or clear
glass, tinted or not, and have letters, words, devices for advertisements or ornamen-
tation, burnt in or otherwise applied, as may be found desirable.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
The manufacture of a combined chimney and shade for gas burners, oil and other
lamps, as described with reference to the drawings, the bonnet of such chimney or
shade serving to carry on its brim an advertisement of any desired kind, while
the crown of the bonnet serves as a reflector for the light generated in the chimney.
