LETTERS PATENT to George Porter, junior, of 23, Cullum St., E.C., in the City
IMPROVE-
of London, Gas and Hot Water Engineer, for the Invention of
MENTS IN GLASS, OPAL, AND OTHER SHADES AND REFLECTORS, AND METHOD OF
SUPPORTING AND AFFIXING THEM ON TO GAS AND OIL BURNERS."
Scaled the 1st September 1876, and dated the 22nd March 1876.
PROVISIONAL SPECIFICATION left by the said George Porter at the Office
of the Commissioners of Patents on the 22nd March 1876.
GEORGE PORTER, junior, of 23, Cullum St., E.C., in the City of London, Gas and
Hot Water Engineer. "IMPROVEMENTS IN GLASS, OPAL, AND OTHER SHADES AND
REFLECTORS, AND METHOD OF SUPPORTING AND AFFIXING THEM ON TO GAS AND
OIL BURNERS."
These improvements relate to the novel construction of shades or reflectors for
argand and other gas or oil burners, and are designed to dispense with the wire
or other supports hitherto used for carrying shades or reflectors over burners, to
obtain greater reflecting power, and to impart a more handsome appearance to the
shade.
My Invention consists in forming a shade or reflector in one or more pieces, the
lower portion having a foot, so as to be affixed to the burner by means of set
screws, clips, rings, or other fastening, or it may simply rest upon the burner.
When made in more than one piece the outer edge of the lower portion or screen
has either a plain edge or turned up flange, so that the upper portion or reflector
nay seat into or rest upon it. The outer edge of the upper portion or reflector has
cither a plain edge or turned down flange, so as to rest upon or scat into the
lower portion or screen, thus forming a complete shade and reflector. In manu-
facturing them I make by preference the upper portion or reflector of opal, and the
lower portion or screen of part opal and part glass, or entirely of glass with a
part obscured, the light being reflected through the clear space; they may
however be made entirely of opal or other material and in various colours, and can
also be adapted for fish-tail and other gas or oil burners, by making them with an
enlarged opening at the top. The upper and lower portion may be made so as
to be used with the ordinary shades or reflectors now in use.

said George Porter in the Great Seal Patent Office on the 7th September
1876.
GEORGE PORTER, junior, of 23, Cullum Street, E.C., in the City of London,
Gas and Hot Water Engineer. "IMPROVEMENTS IN GLASS, OPAL, AND OTHER
SHADES AND REFLECTORS, AND METHOD OF SUPPORTING AND AFFIXING THEM ON
TO GAS AND OIL BURNERS."
These improvements relate to the novel construction of shades or reflectors for
argand and other gas or oil burners, and are designed to dispense with the wire
or other supports hitherto used for carrying shades or reflectors over burners to
obtain greater reflecting power and to impart a more handsome appearance to the
shade.
My Invention consists in forming a shade and reflector in one or more pieces
made of opal or glass, or a combination of opal and glass or other suitable material
for reflecting light, the lower portion having a foot, so as to be affixed to the
burner by means of set screws, clips, rings, or other fastenings, or it may simply
rest upon the burner, the lower part thus forming a support for the upper part,
and thereby dispensing with the wire or other supports hitherto used for carrying
shades or reflectors. The lower portion is made partly opaque or obscured and
partly clear glass; the opaque or obscured part reaches from the foot to about two-
thirds of the distance upwards, so as to screen the flame of the burner from view,
the clear part extending from that point to the outer edge, through which the
light is reflected by means of the upper portion or reflector. When made in more
than one piece the outer edge of the lower shade or reflector support has a plain
flat edge, and the outer edge of the upper shade or reflector has a turned down
flange, so as to fit over the outside edge of the lower shade, and is thus held in
its proper position. The lower shade or reflector support is also made with a
turned up flange on its outer edge, so as to support a shade or reflector with a
plain edge, or any ordinary shade or reflector now in use.
The manner in which I carry my said Invention into practice is clearly
illustrated in the accompanying Drawing, which I will now proceed to describe.
Fig. 1 is a sectional elevation of the bottom shade or reflector support having
a plain flat edge; E and B is the bottom or foot, which is affixed to the burner.
Fig. 2 is a sectional elevation of the upper shade or reflector having a turned
down flange F, which fits over the edge E of Figure 1.
Fig. 3 is a sectional elevation of the bottom shade or reflector support having
a turned up flange T, into which any ordinary shade or reflector now in use with
a plain straight edge, such as the edge S of Fig. 4, will seat.
Fig. 5 is a plan of Fig. 1; and Figure 6 is a plan of Fig. 2.
Figs. 7 and 8 are sectional elevations of a bottom shade and reflector, differing
ornamentally to Figs. 1 and 2, and shewing that whilst adhering to the principal
of the application of the above improvements the ornamental design or size may
be varied.
Having thus fully described the nature of my said Invention, and the manner
of performing the same, I wish it to be understood that I claim,-—
First. A shade and reflector with a foot, so as to affix on to gas or oil burners,
and thus dispense with wire and other supports, as herein described.
Second. A shade for supporting ordinary shades and reflectors now in use, as
herein described.
In witness whereof, I, the said George Porter, junior, have hereunto set my
hand and seal, this Seventh day of September, in the year of our Lord
One thousand eight hundred and seventy-six.
