IMPROVEMENTS IN GAS & LAMP GLOBES AND SHADES
Year: 1885

page_text: This Specification was, upon the 16th day of June 1888, amended under
Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1883.
CHARLES DAIRY, 15 Gilbert Street, Grosvenor Square in the county of Middlesex,
Gentleman do hereby declare the nature of my invention for "IMPROVEMENTS IN
GAS & LAMP GLOBES AND SHADES," to be as follows:-
My invention consists of Improvements in Gas and Lamp Globes and Shades for
gas burners &c and has for its object the utilising of a larger portion of the light
emitted from gas burners &c, and preventing the blackening of ceilings &c, which
results from the burning of gas in ordinary shades or globes.
I am aware that this can be accomplished at least partially by affixing a reflector
to the ordinary globes or shades, but I propose to do it more effectually and
economically by making the globe and reflector in one piece either by blowing
them together in the same mould or by forming them separately and uniting them
afterwards whilst hot &c; I provide them with openings or "sluts" near their
juncture to allow of the escape of the products of combustion, by which means a
much steadier light is obtained together with greater economy of combustion.
Dated this 12th day of December 1885.

Middlesex Dealer in Works of Art, do hereby declare the nature of my said
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My Invention consists of Improvements in Gas and Lamp Globes and Shades
for Gas burners &c and has for its object the utilising of a larger portion of the
light emitted from gas burners &c and preventing the blackening of ceilings &c
which results from the burning of gas in ordinary shades or globes. I am aware
that this can be accomplished at least partially by affixing a reflector to the
ordinary globes or shades, but I propose to do it more effectually and economically
by making the globe and reflector in one piece either by blowing them together
in the same mould or by forming them separately and uniting them afterwards
whilst hot etc, I provide them with slots or sluts near their juncture to allow of
the escape of the products of combustion, by which means a much steadier light is
obtained together with greater economy of combustion.
My Invention therefore relates to combining the globe or shade and reflector in
one structure and consists in a globe with the top or roof intact thus forming a
very efficient reflector whilst the products of combustion are given exit by horizontal
slots or holes.
The slots or holes are so placed as not to weaken the globe and are found in
practice to be best if placed just above the greatest diameter of the globe.
I make my globes of any suitable shape and material (preferably of glass) and
they are applicable to any artificial light.
In order that my Invention may be more clearly understood I annex a sheet of
Drawings hereto in which
Figure 1 is a top view of globe shewing position of the slots or holes for egress
of products of combustion and the ordinary size of reflecting surface.
Figure 2 is a side elevation of the same showing the slots or holes and the
diameter of aperture at base for ingress of atmospheric air.
By means of my invention all smoke is consumed, blackened ceilings and firing
of curtains &c prevented, and a much larger amount of light concentrated down-
wards. The flame is kept steadier giving a more agreeable light and preserving
the glass from breaking so readily under the effects of draughts.
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 I make
no general claim to a lamp globe or shade and reflector combined in one piece but
what I claim is :-
A Gas or lamp Globe or Shade and reflector combined in one piece having horizontal
slots or apertures at or near the greatest diameter of the globe all substantially as and
for the purposes hereinbefore described and shown in the accompanying sheet of
drawings.
