COMPLETE SPECIFICATION.
Improved Means of Reflecting Gas or other Artificial Light.
1, JOHN COBBE, of 6 & 7, Adelphi Terrace, in the County of Middlesex,
Theatrical Manager, 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 :-
In Specification to Letters Patent No. 17,223 of 1887 I have illustrated certain
means for reflecting the light of gas burners or other flames on to the ceiling of a
room from whence it is thrown down and diffused throughout the apartment,
while in Specification to Letters Patent No. 476 of 1888 I have shown a modifi-
cation of same.
My present invention relates to improved reflectors by which the light may be
thrown upward to the ceiling or downward in the usual way as desired, or by which
it may be thrown in both ways.
To clearly explain my invention I will describe it with reference to the accom-
panying drawing in which :-
Fig. 1 shows a lamp having my improved shade or reflector in the position adapted
to throw the light downwards.
Fig. 2 shows the shade adapted to throw the light upwards.

page_text: Fig. 5 a plan of same.
The shade or reflector as shown in Figs. 1, 2 and 3 consists of a number of leaves
or plates a pivoted on the arms & extending from a ring or collar e carried by the
gallery of the lamp. The plates a are so balanced that by a touch their position
may be altered so as to throw the light up or down. To support the leaves when
in the position shown in Fig. 1 the arms have a bent portion & extending therefrom
as shown. If desired a iube or piece e of flexible material such as a fabric
coloured or otherwise may be secured to the inside edges of the leaves of the
reflector and to the ring e so as to subdue the light when the latter is reflected
downwards.
The leaves or plates a instead of overlapping may simply abut, in which case
one, two, or more may be turned in the opposite direction to the rest so as to alter
the direction of a portion of the light. Fig. 4 shows a reflector for throwing the
light both up and down, the reflector being provided for this purpose with the
surfaces and h.
"
The upwardly reflecting surface g is cut away as shown to allow of a portion
of the light passing through the same so as to be reflected downwardly. To
subdue this part of the light the open spaces may be filled with some fabric opal
or coloured glass or the like. This reflector may be carried on the lamp or light in
any convenient way, as for instance, by the means shown in my Specification
No. 476 of 1888 before referred to.
It must be understood that I do not confine myself to the particular form of
shades shown as these may vary in many instances and may be applied as will be
evident to gas, electric light and other lights, but
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. A shade or reflector composed of leaves or plates pivoted on arms or adapted
to be reversed to throw the light up or down, substantially as described.
2. The combination with a shade adapted to throw the light both up and down,
of a fabric or the like arranged to subdue the light when thrown downward, sub-
stantially as described.
Dated this 19th day of March 1891.
