IMPROVEMENTS IN APPARATUS FOR TRANSMITTING LIGHT FROM LAMP AND OTHER BURNERS
Year: 1844

page_text: TO ALL TO WHOM, THESE PRESENTS, SHALL COME, I, HENRY
BORRISKILL TAYLOR, of Piccadilly, Lamp Manufacturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventh day of November, in the eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Henry Borriskill Taylor; Her especial licence, full power, sole privilege and
authority, that I, the said Henry Borriskill Taylor, my exors, admors, and
assigns, or such others as I, the said Henry Borriskill Taylor, my exors,
adiñors, or assigns, should at any time agree, with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend; within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
APPARATUS FOR TRANSMITTING LIGHT FROM LAMP AND OTHER BURNERS;" in which
said Letters Patent is contained a proviso that I, the said Henry Borriskill
Taylor, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as .in
and by the same; reference being thereunto had, will more fully and at large
appear.
. NOW KNOW YE, that in compliance with the said proviso; I; the said
Henry Borriskill Taylor, do hereby declare that the nature of my said Inven

page_text: My Invention consists of applying certain pressed or cut glasses to transmit
the light of an oil or other lamp, or of a glass burner, or of a candle lamp, either
upwards or downwards, or both, under more advantageous circumstances than
heretofore.
DESCRIPTION OF THE DRAWING.
Figure 1 represents pressed or cut glasses, according to my Invention,
applied to a table lamp, the upper part of the lamp and the ordinary glass
shade and chimney being shown in dotted lines. a, b, are two conical glasses,
which are pressed or cut on their outer surfaces with radial cuts or corruga-
tions, as is clearly shown. The glass a being for the purpose of casting the
light downwards, and this is done without taking away any light from above,
by which means it will be found that the light will be more intense below the
burner and for some distance around than when the glass a is not applied; and
the glass b in like manner distributes the light upwards when used, so that the
light above the lamp or other burners is much more intense than when the
glass b is not applied; and this is effected without taking away any light from
below. I would remark that it is not necessary that both glasses a and b
should be used at the same time, and the upper one b will seldom be required
in lamps which are suspended, and where the light is desired to be cast down-
wards into the room; and it will be found that in using these glasses that
they do not show any shadow on the ordinary glass shade c when one is used,
and there does not appear to be any reduction of the light passing through
such shade c, whatever be its shape, when the glasses a and b are used;
and the only difference perceived in respect to any lamp or gas burner,
when using and when not using the glasses a and b, is, that there is much
more light above and below when they are used than when they are not
used. The glass b rests on the glass a, and is supported thereby, and the
glass a supported by the frame d, d, or by any convenient means.
Figure 2 shows a section of the glasses a and b, and it should be remarked
that whatever be the flame the glasses may be applied to, that the lower one a
is at its upper part to come about level with the middle of the flame, and,
therefore, the upper glass 6 will at its lowest part come to the middle of the
fime, as is indicated in Figure 1. Although I believe the best shape for the
glasses a and b is that shown at Figures 1, 2, 3, and 4, the two last-mentioned

page_text: Figures showing a plan and edge view of one of them, yet the shape may
be varied; and although I prefer to press or cut them with radial cuts or
corrugations in the manner shewn at Figures 1, 2, 3, and 4, yet the pressing
or cutting thereof may be varied; thus, in Figure 5 is shown the section of
part of a glass a or 6 where the cuts or corrugations are on the outer surface,
and Figure 6 shows a section of a glass a or b, where the cuts or corrugations
are on the under surface, and they may be more or less sharp. Figure 7 shows
the section of part of a glass a or 6 where the cuts or corrugations are formed
above and below.
Having thus described the nature of my Invention, and the best means of
performing the same, I would wish it to be understood that what I claim is
the application of glasses, such as a and b, to diffuse light, as herein described.
In witness whereof, I, the said Henry Borriskill Taylor, have hereunto
set my hand and seal, this Sixth day of May, in the year of our Lord
One thousand eight hundred and forty-five.
