TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
SAMUEL CLARKE, of 55, Albany Street, Regent's Park, in the County
of Middlesex, Lamp and Candle Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of November, in the
year of our Lord One thousand eight hundred and fifty-two, in the
sixteenth ycar of Her Reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Samuel Clarke, Her special
licence that I, the said Samuel Clarke, my executors, administra-
tors, and assigns, or such others as I, the said Samuel Clarke, my
executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland; the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN LAMPS," upon the condition (amongst
others) that I, the said Samuel Clarke, by an instrument in writing
under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar mouths next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Clarke, do hereby declaré
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof (that is to say):
This Invention consists of employing vulcanized india rubber as
elastic surfaces to receive the chimnies and other glasses of candle

page_text: and other lamps. And in order that my said Invention may be inost
fully understood, and readily carried into effect, I will proceed to
describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a candle lamp, having my improvements applied
thereto. Figure 2, is a plan of the gallery: a, is the glass, which
may be of other form at its upper parts, so long as it is turned out-
wards at its lower edge, as shewn. The gallery is made-with- three
projections, b, c, c: the projection b, has simply a notch or undercut
part, to receive the end of the glass a, whilst the projections c, c,
have each a piece of vulcanized india rubber fixed across or clipped,
as is shown; hence, when the glass a, is in its place, the pieces of
india rubber will have a tendency to hold the edge of the glass
under the undercut part of the projection b, and thus will the glass
be securely retained in its place, and yet when desired the glass
inay be readily removed, as it will be simply necessary to press the
edge of the glass back, and thus to overcome the elasticity of the
vulcanized india rubber, and the glass will come away.
Figure 3, shows the holder or frame of a glass shade, having
another form of my Invention applied thereto. d, is the ring of
the frame on which the shade e, is received and supported; and the pc-
culiarity is, that a ring of vulcanized india rubber f, is interposed
between the inetal ring d, and the glass shade e.
Figure 4, shows a plan, and Figure 5, an elevation, of the gallery or
glass holder of a gas lamp, which has three projections g, g, in each
of which is fixed a piece of vulcanized india rubber, which is clipped
securely between the parts of the metal projections, as shewn, or the
same may be otherwise fixed.
Having thus described the nature of my Invention, and the
manner of performing the same, I would have it understood that
what I claim is, the application of vulcanized india rubber to the
galleries or glass holders of lamps, as herein explained.

three.
