Norfolk, for the Inventioni of." IMPROVEMENTS IN APPARATUS TO PROTECT
THE FLAME OF A CANDLE FROM DRAUGHT,"
PROVISIONAL SPECIFICATION left by the said Henry Albert Bartlett
at the Office of the Commissioners of Patents, with his Petition, on the
20th March 1861.
.I, HENRY ALBERT. BARTLETT, of Thetford,, in the County of Norfolk, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN APPARATUS
TO PROTECT THE FLAME OF A CANDLE PROM DRAUGHT," to be as follows:-
The object of this Invention is to protect the flame of a candle from the
action of draughts when exposed to the same, or when being removed or carried
from place to place. For this purpose a glass chimney carried by a suitable
support. attached to the candlestick is caused to surround the flame of the
candle. The position of the chimney is capable of adjustment upon its
support, so that it may be lowered as the candle is consumed; and in order
that my Invention may be readily applied to candlesticks of the ordinary con-
struction in common use, the support upon which the holder for the glass
chimney, slides is, so constructed that it can be readily attached by set screws
or otherwise to the stem or socket of an ordinary candlestick..

page_text: Another part of my Invention consists in forming a spring clip suitable for
embracing candles of different sizes, and capable of supporting a light glass
chimney for the purpose of protecting the flame of the candle from draughts.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Albert Bartlett in the Great Seal Patent Office on
the 19th September 1861.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ALBERT BARTLETT, of Thetford, in the County of Norfolk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of March, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Henry Albert Bartlett, Her special licence that I, the said
Henry Albert Bartlett, my executors, administrators, and assigns, or such
others as I, the said Henry Albert Bartlett, 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 APPARATUS TO PROTECT THE FLAME OF A CANDLE
FROM DRAUGHT," upon the condition (amongst others) that I, the said Henry
Albert Bartlett, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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 months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Albert Bartlett, do hereby
declare 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 :-
.
The object of this Invention is to protect the flame of a candle from the
action of draughts when exposed to the same, or, when being moved or carried
from place to place. For this purpose a glass chimney carried by a suitable
support attached to the candlestick is caused to surround the flame of the
candle The position of the chimney is capable of adjustment upon its

page_text: support, so that it may be lowered as the candle is consumed; and in order
that my Invention may be readily applied to candlesticks of the ordinary con-
struction in common use, the support upon which the holder for the glass
chimney.slides is so constructed that it can be readily attached by set screws
or otherwise to the stem or socket of an ordinary candlestick.
Another part of my Invention'consists in forming a spring clip suitable. for
embracing candles of different sizes, and capable of supporting a light glass.
chimney for the purpose of protecting the flame of the candle from draughts..
And in order that my Invention may be most fully understood and readily
carried into practice, I will proceed to describe the Drawing hereunto
Figure 1 shews a vertical section, and Figure 2 a plan, of apparatus con-
structed according to my Invention, suitably arranged for being fixed on the
top of an ordinary candlestick, in order to shield the flame of the candle from
draught when exposed thereto, or when being moved from place to place.
a, b, are clips so constructed as to be readily attached to the upper part of
an ordinary candlestick, and secured thereto by the tightening screws b¹, b¹, as
shewn; c is a vertical support, which may be of round, square, triangular,
bayonet, or other form, fixed to the upper side of the clip a; and d is the slide
and holder which carries and supports the glass chimney e.
glass chimney e. The glass holder
consists of a plate d' with curved arms fixed to the slide d, and upon which
the narrow flange at the bottom of the glass chimney rests, there being pro-
jections d² on the plate d¹, which pass up a short distance into the interior of
the chimney; e¹ is another curved plate which partly surrounds the lower end
of the external circumference of the chimney, and rests upon the upper edge
of the flanch, so that when the plates d₁ and e' are drawn together by the
screw e, that part of the flanch of the chimney which is enclosed between the
plates d, e, will be securely retained, and thus support the chimney. Pro-
jections are formed on one of the plates d¹, e¹, outside the edge of the flanch
on the glass to keep the two plates parallel when drawn together by the
tightening screw e². The holder d is retained in any desired position on the
vertical support c by the spring d*, or by a set screw.
Figure 3 shews a section, and Figure 4 a plan, of another arrangement of
apparatus for supporting a light glass chimney to protect the flame of a candle
from draught according to my Invention, and consists in attaching and
supporting the glass holder d to a spring clip f, so constructed as to be
capable of embracing candles of different sizes. The construction of the parts

page_text: for holding the glass chimney. are similar to that previously described, and
marked with similar letters of reference. The spring clip f consists of a short
split tube of light metal, to which the ring f¹ is rivetted; a set screw f³ passes
through the ring f, so as to press upon one side. of the split. tube f, and thus
close and retain it in any desired position upon the candle; f³ is an arm on
the ring, connecting it to the glass holder d.
Figures 5 and 6 shew two views of another. arrangement of a spring clip
and glass.holder, which consists of a short split tube f to slip over the candle,
furnished with light spring arms f" for supporting the glass chimney e.:
Having thus described the nature of my Invention, and the manner of
carrying the same into practice, I would have it understood that I do not
confine myself to the exact details herein described; but what I claim is, the
arrangement of apparatus for protecting the flame of a candle from draught,
as described in respect to Figures 1, 2, 3, 4, 5, and 6 of the Drawing.
.
In witness whereof, I, the said Henry Albert Bartlett, have hereunto
set my hand and seal; this Seventeenth day of September, in the year
of our Lord One thousand eight hundred and sixty-one.
