Complete Specification Left, 13th Sept., 1888
Complete Specification Accepted, 19th Oct., 1888
I, JOHN COBBE of 22 Berners Street in the County of Middlesex, Theatrical
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of reflecting gas and other artificial
light.
In the ordinary arrangement of a gas or other burner it is surrounded by a gallery
upon which rests a globe or shade or both, the arrangement being such that the light
is reflected in a downward direction or if a plain glass globe alone is employed the
light is equally diffused in all directions.
The object of my invention is to reflect the main body of the light in an upward
direction so that it may be diffused about the top of the room or apartment and thus
produce a more equal and agreeable lighting in all parts of such apartment.
To this end I employ a more or less opaque shade or reflector, say of an inverted
truncated conical or other form, the angles or "flare" of which will vary depending
upon the distance between the normal level of the light and the height of the ceiling.
Such shade is mounted upon a gallery surrounding the light and may be held thereon
by means of clips such as are now employed for holding globes.
Dated this 14th day of December 1887.

page_text: 1, JOHN COBBE of 22 Berners Street in the County of Middlesex, Theatrical
Manager, do hereby declare the nature of this invention and in what manner tho
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to an improved method of reflecting gas and other artificial
light.
In the ordinary arrangement of a gas or other burner it is surrounded by a gallery
upon which rests a globe or shade or both, the arrangement being such that the light
is reflected in a downward direction, or if a plain glass globe alone is employed the
light is equally diffused in all directions.
The object of my invention is to reflect the main body of the light in an upward
direction so that it may be diffused about the top of the room or apartment and thus
produce a more equal and agreeable lighting in all parts of such apartment.
To this end I employ a more or less opaque shade or reflector, say of an inverted
truncated conical or other form, the angles or
flare" of which will vary depending
upon the distance between the normal level of the light and the height of the ceiling.
Such shade is mounted upon a gallery surrounding the light and may be held thereon
by means of clips such as are now employed for holding globes.
In order that my invention may be clearly understood reference is made to the
accompanying drawings in which :-
Fig. 1 represents the invention as applied to an ordinary gas bracket, and-
Fig. 2 as applied to an ordinary table lamp, in both cases the shade or reflector
being shown in section.
In said drawings A is the shade or reflector made of opaque material and carried
by a suitable gallery B. It will be understood that I do not limit myself to this
particular form of shade or gallery as they may be varied at will without departing
from my invention, for though the form shown will give good results, I prefer to use
an improved construction for which I have applied for Letters Patent No. 476
of 1888.
I am of course aware that opaque or semi-opaque shades of saucer like form have
been used to prevent the rays of light from coming in direct line with the eye, but
such constructions have not so far as I am aware been adapted for reflecting the light
to the ceiling or higher walls in such a manner that an even lighting of the room or
apartment will be obtained.

page_text: 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 :-
The improved method of reflecting gas and other artificial light by means of a
shade or reflector so located with relation to the burner as to be adapted to
throw the rays of light upward and so diffuse the light, substantially as described.
Dated this 13th day of September 1888.
