Improvements in Candle Lamps and in their Manufacture..

I CHARLES WILLIAM BLACKMAN Manager to Messieurs Mappin and Webb of
Oxford Street in the County of Middlesex Silversmiths do hereby declare the
nature of this invention to be as follows:-
.
. According to this invention I form a candle lamp externally to resemble an
ordinary candle and with a spring stem at its lower end to fit into any ordinary
socket used for holding candles so that the candle lamp may be set up in any
ordinary candlestick or chandelier and will give the appearance of an ordinary
candle without the inconvenience of liability to guttering which is always met
with when candles are used.
The exterior of the lamp may be colored to any desired color in imitation of
colored candles or may be of a deadened white appearance in imitation of spermaceti
or wax or other uncolored candles.
To obtain such a deadened white appearance the exterior of the candle lamp
may be electro-plated with silver and be covered with a coating of lacquer or
varnish without previously polishing the electro plated coating but keeping it
dull and dead just as it comes from the bath.
Figure 1 shows a side elevation of a candle lamp formed according to my inven
tion. Figure 2 is a vertical section of the same.
A is a metallic tube with its upper end closed in somewhat as shown at Figure 2
to hold down the candle. B is a cap secured to the lower end of the tube by a
sort of bayonet joint or it might be by other means. CC are springs forming an
expanding spring stem fixed to the underside of the cap B. When this spring
stem is forced downwards into any ordinary socket formed for holding a candle
the springs will bear against the interior of the socket whilst the outer portion of
the cap will rest on the top of the socket and keep the candle lamp upright and
steady. D is a coiled spring within the interior of the tube for pressing up
piston D* to force the candle upwards as in ordinary candle lamps.
E is a tube fitting on to the top of the candle lamp and carrying a cone for
supporting a paper or other shade in the same way as is now commonly done with
candles,

I CHARLES WILLIAM BLACKMAN Manager to Messieurs Mappin and Webb of
Oxford Street in the County of Middlesex Silversmiths 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:—
According to this Invention I form a candle lamp externally to resemble..an
ordinary candle and with a spring stem at its lower end to fit into any ordinary
socket used for holding candles so that the candle lamp may be set up in any
ordinary candle stick or chandelier and will give the appearance of an ordinary
candle without the inconvenience of liability to guttering which is always met
with when candles are used.
The exterior of the lamp may be colored to any desired color in imitation of
colored candles or may be of a deadened white appearance in imitation of spermaceti
or wax or other uncolored candles.
To obtain such a deadened white appearance the exterior of the candle lamp
may be electro plated with silver and be covered with a coating of lacquer or
varnish without previously polishing the electro plated coating but keeping it dull
and dead just as it comes from the bath.
Figure 1 shows a side elevation of a candle lamp formed according to my inven-
tion. Figure 2 is a vertical section of the same.
A is a metallic tube with its upper end closed in somewhat as shown at Figure 2
to hold down the candle. B is a cap secured to the lower end of the tube by a sort
of bayonet joint or a screw or it might be by other means. " C. C. are springs
forming an expanding spring stem fixed to the underside of the cap B. When the
spring stem is forced downwards into any ordinary socket formed for holding a
candle the springs will bear against the interior of the socket whilst the outer
portion of the cap will rest on the top of the socket and keep the candle lamp
upright and steady. D is a coiled spring within the interior of the tube for pressing
up a piston D to force the candle upwards as in ordinary candle lamps.
E is a tube fitting on to the top of the candle lamp and carrying a cone for
supporting a paper or other shade in the same way as is now commonly done with
candles.
A modified way of forming the expanding spring stem of the cap B is shown at
Figures 3 and 4. Figure 3 is a side elevation and Figure 4 a longitudinal section.
The expanding spring stem shown in these Figures is formed of a cylindrical
block C of vulcanized india rubber the diameter of which can be enlarged or
decreased by more or less compressing it between the end of the cap B and the
head of a screw F which screws into a block on the end of the cap as shown at
Figure 4. In Figure 3 the block C of vulcanized india rubber is shown uncom-
pressed. In Figure 4 it is shown to be compressed and its diameter increased.
In this way the diameter of the block can readily be adjusted to make it fit
tightly into any socket.
In place of forming the spring stems in the above ways the stems might simply
be coated with india rubber or cork or such like elastic material to enable it to fit
tightly into the sockets.

page_text: 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 candle lamp formed with a spring or expanding stem at its lower end to fit
into sockets of varying sizes.
2. A candle lamp formed with an expanding spring stem at its lower end
substantially as described and illustrated at Figures 1 and 2.
3. A candle lamp formed with an expanding spring stem at its lower end
substantially as described and illustrated at Figures 3 and 4.
4. A candle lamp formed to resemble an ordinary candle and electro plated
externally with a dull or dead coating of silver and subsequently lacquered or
varnished without previous polishing substantially as described so as to give a
deadened white appearance to the exterior of the candle lamp.
