AUTOMATIC CANDLE SHADE HOLDERS
Year: 1886

do hereby declare the nature of my invention for AUTOMATIC CANDLE SHADE HOLDERS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention consists in the construction of candle shade holders or carriers, which
allow the shade to follow & continually screen the flame as the candle burns down.
Figs. 1 & 2 of the accompanying drawings illustrate two methods of carrying out
my invention. In Fig. 1 I fix at a suitable distance from & parallel to the candle a
a rack 6 or its equivalent. It can either be fixed by a clamp to the candle or in any
suitable way to the candlestick. A pinion e, or its equivalent, working in the rack is
held in the slide d-to the latter is fixed the ring which holds the shade. The slide d
(with the shade) is free to descend on the rack by its own weight. To the axis of the
pinion e I fix one or more than one spoke c, which naturally revolves as the slide
descends & by making them of suitable length the come into contact with the side
of the candle & prevent the slided & the shade from descending. When the candle
burns down to the point of contact of the spoke, the latter is released & the slide
descends until another (or if there is only one the same) spoke whilst revolving, comes
into contact with the candle lower down. The further burning down of the candle
releases the spoke again & so on, & thus the shade follows down the flame as the candle
burns away. In Fig. 2. the rack b (in Fig. 1) is replaced by a suitable stem or guide b,
The slide d holding the
on which are pivoted two or more than two levers c, c, c.
shade is shown in contact with the projecting short end g of the top lever & pressing
by means of its weight the long end of the lever out against the candle, thus
preventing the descent of the shade. As soon as the candle has burnt down to the
point of contact of the lever, the latter is released, the long end swings upwards & the
slide d falls by its weight till it comes into contact with the end g of the second lever,
forcing the long end of the latter out against the candle. The downward progress of
the slide & shade is thus arrested, till the burning down of the candle again releases
The slide d is so
the lever & allows the slide to fall to another lever & so on.
constructed that the levers can fall back away from the flame as soon as d has
descended a little way. In addition to this provision the upper part of the slot in d is

slide.
Having now particularly described and ascertained the nature of my said invention,
& in what manner the same is to be performed, I declare that what I claim is :
1. The construction of automatic candle shade holders, in which the burning of the
candle releases spokes, levers or their equivalents which rotate or swing in a vertical
plane or vertical planes.
2. The construction of such holders substantially as described & illustrated with
reference to Fig. 1. of the accompanying drawings.
3. The construction of such holders substantially as described & illustrated with
reference to Fig. 2. of the accompanying drawings.
