Improvements in Lamp Globes for Illumination, Decorative, and
other Purposes.
We WILLIAM HENRY GRITTON Engineer WILLIAM EDWARDS Gentleman
and HENRY BRINSLEY SHERIDAN Gentleman all of 8 Victoria Street
Westminster in the County of London, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to construct globes for gas and oil lamps used for
illumination decorative and other purposes in such a manner that the flames enclosed
by such globes will not be extinguished by the wind or other air current and the
flickering of the flames be avoided or greatly reduced.
Now according to this invention we construct globes for gas jets, oil lamps
and the like which have to burn in the open air or other draughty places in two
portions.
The lower portion which takes the place of the usual gallery may be made of
metal or of glass or other material or partly of metal and partly of glass or other
material.
The lower portion of the globes is perforated with any suitable number of
apertures to admit air to the flame and also to allow any moisture which may find
it way into or be generated in the globe to drain off.
The upper portions of our improved globes which may be of any size and shape
are made of glass or other suitable transparent material and are perforated with
one, or more apertures to allow the products of combustion to escape from the
globes.
These apertures are covered preferably by means of hoods which prevent rain
and other moisture from entering the globes through the apertures and also prevent
the wind or other air current from passing across the globe and extinguishing the
flame or causing it to flicker. The two portions of the globes may be secured to
each other by means of bayonet joints, screws, spring catches or other suitable
means.
The material of which the globes are composed may be of any suitable color or
colors to give the desired effect:-for example the globe may be of one color and
the hoods of another color.
Globes constructed as hereinbefore described are especially suitable for gas
lighting when the jets are lighted and extinguished by means of apparatus actuated
by electricity.

Improvements in Lamp Globes for Illumination, Decorative, and
other Purposes.
We WILLIAM HENRY GRITTON Engineer WILLIAM EDWARDS Gentleman
and HENRY BRINSLEY SHERIDAN Gentleman all of 8 Victoria Street
Westminster in the County of London 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 :-
The object of this invention is to construct globes for gas oil and other
lamps used for illumination decorative and other purposes in such a manner that
the flames enclosed by such globes will not be extinguished by the wind or other
air current and the flickering of the flames be avoided or greatly reduced.
Now according to this invention we construct globes for gas jets oil lamps
and the like which have to burn in the open air or other draughty places in two
portions.
The lower portion which takes the place of the usual gallery and is hereinafter
called the "gallery" may be made of metal or of glass or other material or partly
of metal and partly of glass or other material.
The lower portion of the globes or gallery is perforated with any suitable
number of apertures to admit air to the flame and also to allow any moisture
which may find its way into or be generated in the globe to drain off.
The upper portions of our improved globes which may be of any size or shape
are made of glass or other suitable transparent material and are perforated with
one or more apertures to allow the products of combustion to escape from the globes.
These apertures are covered preferably by means of hoods which prevent rain
and other moisture from entering the globes through the apertures and also prevent
the wind or other air current passing across the globe and extinguishing the flame
or causing it to flicker.
The two portions of the globes may be secured to each other by means of bayonet
joints, screws, spring catches or other suitable means,
The material of which the globes are composed may be of any suitable color or
colors to give the desired effect :-for example the globe may be of one color and
the hoods of another color.
Globes constructed as hereinbefore described are especially suitable for gas
lighting when the jets are lighted and extinguished by means of apparatus
actuated by electricity and in order that our said invention may be fully under-
stood we will proceed to explain the same with reference to the accompanying
sheet of drawings in which
Fig. 1 represents elevation of the upper portion of a lamp globe constructed
according to this invention.
Fig. 2 is longitudinal section of same.
Fig. 3 is section of bottom portion or gallery.
Fig. 4 is elevation of same."
Fig. 5 is plan of same.
Fig. 6 is elevation of a modified form of lamp globe constructed according to
this invention.
Fig. 7 is section of same.
Fig. 8 is section of lower portion or gallery to support the same.
Fig. 9 is elevation of gallery.
Fig. 10 is plan of same.
The same letters denote the same parts in all the figs.
a is the lower portion of the lamp globes or gallery which may be screwed on to

page_text: the gas pipe in the ordinary way or which may be otherwise attached thereto or to
the gas burner or lamp.
The portion a may be made of glass metal or other suitable material and may be
perforated or have a number of apertures b formed therein to admit air to the
flame or gas jet and to allow any moisture which may be generated in or which
may find its way into the globe to drain off. The upper portion of the globe c
which may be of any suitable size and shape preferably that shewn in the drawings
is made of glass or other suitable transparent or translucent material and is shaped
at the bottom to fit into the lower portion or gallery a as shewn by Sheet 1 of the
drawings or to fit over the same as shewn at Sheet 2.
As shewn at Figs. 8 & 9 the lower portion of the globe or gallery a may be
made with a flange d at the bottom thereof and a packing ring e may rest on the
said flange which ring makes a watertight joint between the two portions of the
globe by the said ring being compressed between the outside of the gallery and
the inside of the portion c or by the said ring being compressed between the flange d
and the lower edge of the portion a.
The portion c of the globe may be made of plain opal or colored glass or it may
be made of colorless glass dipped in or otherwise treated with colored enamel or
other suitable substance.
The upper portion of the globe is provided with apertures f covered with or
surrounded by suitably shaped hoods to prevent a draught or other air current
from passing directly across the globe and also to form an outlet for the products
of combustion.
The two portions a and c of the globes may be attached to each other by means
of a bayonet joint as shewn a pin h being inserted in the portion a and a bayonet
slot k being formed in the portion c or the pin may be secured in the upper portion
of the globe and the slot formed in the gallery a.
Or if the globe is made as shewn at Figs. 1 to 5 we may form a flange at the
bottom of the portion c and secure it to the portion a by means of a set screw and
pins in the same manner as ordinary gas globes are secured to galleries.
In some cases we may silver one half of the portion c on the outside and deposit
copper on the silver such globes being especially suitable for lighting shop windows
from the outside and in other situations where it is only necessary to throw the
light in one direction.
Although we have shewn in the drawings globes circular in cross section yet we
do not confine ourselves to any special configuration or shape of globe for example
if the globes are used with a fish tail or other burner giving a flat flame it may be
advisable to use globes elliptical or approximately elliptical in cross section.
If the gallery
a is made of glass to avoid forming a screw thread therein we
may form the screw in a metal bush as shewn at Fig. 8.
Lamp globes constructed as herein before described are suitable for illumination
decorative and advertising purposes and are especially suited for use with gas jets
lighted and extinguished by means of electricity as by using colored globes and
electrically lighted and extinguished gas jets various combinations of colors may be
intermittently displayed for decorative illumination advertising and other purposes.
Lamp globes constructed as herein before described may also be used for
illumination with candles by making the lower portion of the globe a sufficiently
deep to receive the candle."
The portion a of the globe is preferably provided with male screw thread and
the upper portion c with a female thread so that the two portions of the globe
may be secured to each other and the whole suspended from a cord or wire in the
ordinary way.
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. Globes for gas oil spirit and other lamps consisting of a portion c having

page_text: apertures therein covered with hoods g and a portion or gallery a having
apertures b in the bottom thereof the portions a and c being adapted to be secured
to each other by means of a bayonet joint or other suitable device substantially as
hereinbefore specified.
2. In globes for gas oil spirit and other lamps the combination of au upper
portion of transparent opal ground or colored glass or other suitable material
having hooded apertures therein with a perforated bottom portion a of any
suitable material adapted to be secured to the burner in place of the ordinary
gallery and also to be secured to the portion c by means of a bayonet joint or
other suitable device substantially as hereinbefore specified and for the purposes
stated.
3. Lamp globes constructed and arranged as shewn by the accompanying
drawings.
Date this 12th day of February 1897.
