page_text: Improvements in the Formation of Globes or Shades for Gasaliers
and in "Galleries" for Mounting same.
I ALFRED Fox of Collingwood Street in the City and County of Newcastle upon
Tyne, Tobacconist, do hereby declare the nature of said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
The object of my invention is to obtain a more brilliant light, from any form of
burner, in a downward direction than is possible with globes mounted on any of the
existing forms of "galleries" which invariably intercept the light to a considerable
extent.
"
The improvements consist in forming the globe so as to be supported from the side
instead of upon the bottom and for mounting such globes, the fitting of a "gallery
to the branch of the gasalier in a vertical position so that the burner is the only fitting
below the light to intercept its transmission downward.
I illustrate on the accompanying sheet of drawings a few forms in which I propose
to carry my invention into application but I do not confine myself to these forms
which are capable of various modification.
"
Fig. 1. shows a side elevation in section of one branch of a gasalier with a globe
formed and mounted in -
રી gallery" according to my invention and Fig. 2 an end
front view of the "gallery" with the globe removed. A is the branch having upon
it a screwed part to receive the "gallery" B and projecting to receive the burner
socket C into which is screwed the burner D, unless formed with the socket-E is the
globe having formed upon its side a projecting opening with a rim or flange to fit into
the sunk rim F of the "gallery" which is eccentric to the opening through which the
rim or flange on the globe inserted so that it may enter at an angle as indicated
by dotted lines on Fig. 1, and being inserted will be securely held in the sunk rim
without screws or other appliances for holding it. The globe E is open at top but
closed at bottom, as I prefer to make it and the lower segment of the globe may be
left of clear glass if preferred when the upper portion is obscured coloured or other-
wise ornamented. The burner socket C is curved downward so as to bring the light
nearer to the bottom of the globe.

page_text: Fig. 3 shows another form of globe E in which the projecting opening with the
rim or flange is near the bottom of the globe and the burner socket C projects straight
into it or may be curved downward as shewn by dotted lines.

The sunk rim F of the "gallery may not be continued entirely round but may be
made with breaks in it as shown by Figs. 4 and 5 the globe resting in the lower
portion or portions of the rim and being held securely by the upper portion. In such
cases the globe is made with a rim or flange to correspond which having been inserted,
the globe is turned into its upright position.-Figs. 6 and 7 show two forms of globes
with projecting rim or flange so formed and in positions to be inserted into the
spaces in the gallery "—It is obvious that the "gallery" may be made to receive
the globe in other forms and that screws or other appliances may be used to secure it
therein as shewn by Figs. 8 and 9 in which the sunk rim F on the "gallery" B is
carried only half round and the globe E resting in lower portion is secured by a
screw G inserted through the top of the "gallery" but I prefer to dispense with all
such fittings and to form it as shown on Figs. 1. 2, and 3.
It will be seen that no obstruction exists to the transmission downward of the light
except the thin tube forming the burner socket and by experiments I have found a
very great improvement in the light, with equal consumption, as compared with globes
formed and mounted in the usual manner.
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 :-
1st. The improved construction of globes or shades for gasaliers by which they are
adapted to be mounted in and supported by a "gallery" standing vertically to the
branch of the gasalier.
2nd. For the purpose of mounting and supporting globes or shades so constructed
the application of "galleries" fitted vertically on the branch of the gasalier in any
of the forms shown or merely modified forms.
3rd. Mounting and supporting globes or shades of gasaliers in vertical "galleries"
for the purpose of obtaining an unobstructed transmission of light downward in the
manner substantially as described and shewn.
Dated this 10th day of October 1888.
