Improvements in Lanterns for use in Gas Lighting.
I, SIMON BIHELLER of 70 & 71 Chiswell Street in the City of London, Agent (A
communication from abroad by the Actiengesellschaft vorm. C. H. Stobwasser & Co.,
Manufacturers of 156 Reichenberger Strasse Berlin, German Empire, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in Lanterns for use in Gas Lighting of that
class which consists of an upper part of metal with a metal chimney (with or without
a second, inner, chimney) and a closed lower part of Glass forming the body of the
lantern. This lower part of glass, usually in the form of a section of a sphere or of a
cylinder terminating in a hemisphere, is attached to a rim of metal capable of being
secured to the upper part by suitable fastenings. Now hitherto, if access was to be
gained to the burner, the glass part with its metal rim had to be entirely removed.
Where the burner or burners are attached to a pendant tube or tubes, as is usual in
hanging lanterns for incandescent gas light, the construction is improved by providing
the metal rim carrying the glass part with lugs sliding on the pendant tubes or rods
connecting the burner with the top of the lantern and the gas-supply. By this
means the Glass (Globe) remains attached to the lantern by the lugs even when the
fastenings are loosened. It then slides downward along the pendant tubes or rods
and gives access to the .buruer or burners.
Heretofore, when the lantern was to be lighted the Glass (Globe) had to be lowered.
According to the present invention however, a flap is provided in the chimney and
so mounted that, if the lamp requires lighting (if there is no pilot flame, or if the
pilot flame is not burning) a taper or the like pushed against the flap moves it aside
and allows the flame of the taper to reach the gas within the lantern, the flap closing
again automatically when the taper is removed.

page_text: This invention relates to improvements in Lanterns for use in Gas-Lighting of
that class which consists of an upper part of metal with a metal chimney (with or
without a second, inner, chimney) and a closed lower part of Glass forming the
body of the lantern. This lower part of glass (generally called the "globe") is
usually in the form of a section of a sphere or of a cylinder terminating in a 5
hemisphere and attached to a rim or collar of metal capable of being secured to
the upper part by suitable fastenings. Now hitherto, if access was to be gained to
the burner, the glass part with its metal rim had to be entirely removed and
when the lantern was to be lighted the glass "Globe" had to be lowered. According
to the present invention however, the lantern is so constructed that the globe 1
need not be lowered for merely lighting the flame etc. and when lowered
remains attached to the lantern.
The accompanying drawings illustrate a lantern enclosing an incandescent gas
light and embodying this invention,
Fig. 1 of the drawings is an elevation (with the glass part in section) showing the 1
lantern when in use, dotted lines indicating the position of certain parts when the
globe is lowered.
Fig. 2 is a plan of the collar carrying the globe and
Fig. 3 a sectional elevation of said collar, taken along the line X X Fig. 2.
In these drawings A is the metal chimney of the lantern, B B are the pendant 2
parts carrying the burners C C as will be readily understood; D is the glass globe
carried by the collar E. This collar is separately shown in Figs. 2 and 3. Screws se
serve to attach the glass shade or globe to the collar as usual.

On the collar E are provided lugs or brackets F F with slots ff embracing the
upright parts B B of the lantern. G G are pins for retaining the collar in place. It 2
is obvious from the drawing that the collar with the globe slides up and down on
the parts B B being retained when raised by a suitable catch or fastening whilst the
cross part 6 connecting the parts B B prevents it falling too far. If the pins G G
are removed the collar can be taken off. It will be seen that the globe can
be lowered so as to give access to the interior of the lantern, for cleaning, replacing 3
"mantles or the like without the necessity of entirely removing it from the lantern.
A flap H is provided in the chimney A and so mounted that, if the lamp requires
lighting (if there is no "pilot flame," or if the "pilot flame" is not burning) a taper
or the like pushed against the flap moves it aside and allows the flame of the taper to
reach the gas within the lantern, the flap closing again automatically when the taper 3
is removed.
"
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. A lantern for use in Gaslighting wherein the collar carrying the globe is so con-
nected with the upright parts of the lantern, that the globe can be lowered, permitting
access to the interior, without being entirely removed, substantially as specified and
shown in the drawings.
2. In a lantern for use in gaslighting the use of the flap H, as and for the purpose
hereinabove set forth.
