Year: 1879

page_text: LETTERS PATENT to James Langton Clarke, of the Common, Ealing, in the
County of Middlesex, Clerk, for the Invention of "AN IMPROVED METHOD OF
AND APPARATUS FOR SUPPORTING CANDLE SHADES."
Sealed the 30th September 1879, and dated the 16th May 1879.
PROVISIONAL SPECIFICATION left by the said James Langton Clarke at
.
the Office of the Commissioners of Patents on the 16th May 1879.
JAMES LANGTON CLARKE, of the Common, Ealing, in the County of Middlesex, Clerk.
"AN IMPROVED METHOD OF AND APPARATUS FOR SUPPORTING CANDLE SHADES."
My improved method and apparatus consists of a special adaptation of an ordinary
shade holder to the lychnophylax, which lychnophylax is described in the Specifica-
tion filed in pursuance of Letters Patent for "An Improved Method of and Apparatus
for Preventing Candles from Guttering," granted to me, dated 3rd February 1872,
and numbered 349. The ordinary shade holder, either with or without sliding
adjustment. is attached to the candle by a spring clip, which has to be moved down
from time to time as the candle burns. By attaching the shade holder to the
lychnophylax instead of to the candle it is rendered self acting, and noves down
with the lychnophylax. My present Invention consists in an improved method of
attaching a shade holder to the lychnophylax. The lychnophylax has a saucer, as
described in the said Specification, the edge of which saucer is turned over inwards.
Instead therefore of using any of the forms of the spring clip which is now attached
to the rod on which the rim that carries the shade is supported, I attach, at right
angles to the supporting rod about three quarters of a circle of spring wire of suit-
able thickness and strength, and of a diameter slightly larger than the saucer of the
lychnophylax. All that is necessary to attach the shade holder to the lychnophylax
is to compress the circular spring wire till it is small enough to slip into the saucer,
when the outward pressure of the spring wire retains the shade holder firmly in its
place. This method of attachment is almost invisible when the candle is lighted,
and does not obstruct the light. The supporting rod is set back according to the
size of the rim on which the shade hangs, so as to bring it exactly concentric with
the lychnophylax.

"AN IMPROVED METHOD OF AND APPARATUS FOR SUPPORTING CANDLE SHADES."
My improved method and apparatus consists of a special adaptation of an ordinary
shadeholder to the lychnophylax, which lychnophylax is described in the Specifica-
tion filed in pursuance of Letters Patent for "An Improved Method of and Apparatus
for Preventing Candles from Guttering," granted to me, dated 3rd February 1872,
and numbered 349.
The ordinary shadeholder, either with or without sliding adjustment, is usually
attached to the candle by a spring clip, which has to be moved down from time to
time as the candle burns. By attaching the shadeholder to the lychnophylax instead
of to the candle, it is rendered self-acting, and moves down with the lychnophylax.
The method which I employ for attaching the shadeholder to the lychnophylax
is shewn in Fig. A. The lychnophylax has a saucer, as described in the said Speci-
fication, the edge of which is turned over inwards; and I attach at right angles to
the rod a, a, which supports the rim that carries the shade about three quarters of
a circle of spring wire b, b, of suitable thickness and strength, the diameter of the
circle being slightly larger than the interior diameter of the saucer of the lychno-
phylax. The supporting rod a, a, is set back at c sufficiently to allow the sliding
adjustment to move down clear of the exterior of the saucer of the lychnophylax,
and also so as to bring the rim exactly concentric with the lychnophylax.
All that is required to attach the shadeholder to the lychnophylax is to compress
the circular spring wire till it is small enough to slip into the saucer, when the
outward pressure of the spring wire retains, the shadeholder firmly in its place.
Fig. B shews the shadeholder affixed to the lychnophylax.
I do not claim as my Invention a shadeholder moving down automatically as the
candle burns, for such contrivances have been used before. All that I claim as my
Invention is the special adaptation herein before described, constructed substantially
as herein before described, by means of which the ordinary shadeholder is adapted
to the lychnophylax by the method of attachment herein before described.
In witness whereof, I, the said James Langton Clarke, have hereunto set my
hand and seal, this Eleventh day of November, in the year of our Lord
1879.
JAMES LANGTON CLARKE. (L.S.)
