Improved Method of Adapting Candelabra for the Electric Light.
BERNARD MERVYN DRAKE and JOHN MARSHALL GORHAM, Electrical Engineers,
of 66, Victoria Street, Westminster, London, S.W., do hereby declare the nature
of this invention to be as follows:-
It is frequently found, in own candelabra and candlesticks, that it is impractic-
able to carry the wires in the inside of the arms, and in most cases it has been
usual to place the flexible cords outside and attach them at intervals to the arms.
This arrangement, apart from its unsightliness, renders it difficult for the
candelabra to be efficiently cleaned. To obviate this difficulty, we carry one
flexible cord through the imitation candle in the centre, which can usually be
drilled for the purpose, and from this point we distribute the cord underneath
the shades to the connections between the different lamps, these being made at
the top of the candle, instead of from below. The shades may be made larger
so as to minimise the space across which the wires would have to bridge, and if
made so as to touch, the cord will be invisible.

Improved Method of Adapting Candelabra for the Electric Light.
We, BERNARD MERVYN DRAKE and JOHN MARSHALL GORHAM, Electrical
Engineers, both of GG, Victoria Street, Westminster, London, S.W., 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:-
It is frequently found, in adapting clients own candelabra and candlesticks,
that it is impracticable to carry the wires in the inside of the arms, and in most
cases it has been usual to place the flexible cord outside, and attach it at intervals
to the arms.
This arrangement apart from its unsightliness, renders its difficult
for the candelabra to be efficiently cleaned.
Fig. 1 shews the detail of the arrangement about to be described;
Fig. 2 is the elevation on a small scale.
Fig. 3 is the plan of a 5 light candelabra.
To obviate this difficulty we carry one flexible cord A through the imitation
candle B by means of an inner tube E in the centre to the lampholder D from

page_text: which point we distribute the cord underneath the shades to the connections
between the different lamps in series, these being made at the top of the candle
instead of from below. The shades may be larger so as to minimise the space
across which the wires would have to bridge, and if made so as to touch as Fig. 2,
the cord will be invisible. In combination with the above, a detachable lamp
holder is used, consisting of the standard type miniature bayonet socket lamp
.holder to which is fitted a metal conical tube, which drops on the tube E at
point G, whereby connection is made so that the wiring and lamps can be easily
removed for the purpose of cleaning. If more convenient, the wires of course
can be connected in parallel. The tube E is made detachable from the central
candle socket by means of a metal connecting plug, F which makes automatic
electrical connection by means of the said brass pins.
Having now particularly described and ascertained the nature of our said
invention and in what the same is to be performed, we declare that what we
claim is
(1) The method of conveying current to a number of electric lamps in one
fitting, by conductors suspended from one light to the other and concealed by
shades.
(2) In combination with the above the use of a detachable lamp holder to which
the wiring is connected so that the lamps and wiring can be easily removed,
substantially as described.
