AN IMPROVED CANDLESTICK
Year: 1860

page_text: LETTERS PATENT to Edmond Armand Louis D'Argy, of 29, Boulevart
St. Martin, Paris, in the Empire of France, Manufacturer, for the
Invention of "AN IMPROVED CANDLESTICK."
Sealed the 13th November 1860, and dated the 30th May 1860.
PROVISIONAL SPECIFICATION left by the said Edmond Armand Louis
D'Argy at the Office of the Commissioners of Patents, with his Petition,
on the 30th May 1860.
I, EDMOND ARMAND LOUIS D'ARGY, of 29, Boulevart St. Martin, Paris,
in the Empire of France, Manufacturer, do hereby declare the nature of
the said Invention for "AN IMPROVED CANDLESTICK," to be as follows:-
My Invention relates to a new arrangement of candle lamp candlestick
& save-all, in which a candle may be exposed to the strongest draughts
without liability to gutter or run down, or of the light being extinguished. It
consists of a tube having interior spiral grooves, in which the candlestick or
holder engages; in this groove tube I somewhat tightly fit a second tube,
carrying a glass globe, which is held in position jointly by means of rings of
india-rubber & another tube fitting inside the first. In this manner the
globe is held between the two tubes, and remains stationary.
As fast as the candle burns away it is raised by turning the grooved tube,
thereby causing it to rise, and being sheltered by the globe, may be exposed

page_text: to strong currents of air without fear of extinguishing the light, or of the
candle guttering; I also apply this globe to ordinary candlesticks and
save-alls.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edmond Armand Louis D'Argy in the Great Seal Patent
Office on the 21st November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMOND
ARMAND LOUIS D'ARGY, of 29, Boulevart St. Martin, Paris, in the Empire
of France, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of May, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign, did
for Herself, Her heirs and successors, give and grant unto me, the said
Edmond Armand Louis D'Argy, Her special licence that I, the said Edmond
Armand Louis D'Argy, my executors, administrators, and assigns, or such
others as I, the said Edmond Armand Louis D'Argy, my executors, adminis-
trators, 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 "AN IMPROVED CANDLESTICK," upon the condition
(amongst others) that I, the said Edmond Armand Louis D'Argy, 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 Edmond Armand Louis D'Argy, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the annexed Drawings and
to the letters of reference marked thereon, that is to say :-
My Invention relates to new arrangements of candlesticks, save-all, &c., of
any form and shape, which has (over the arrangements made use of beretofore
in apparatus of the same description) great advantages.

page_text: The Invention is illustrated in the annexed Drawings, where Fig. 1 shows
an elevation of a candlestick provided with my own improvements; Fig. 2
shows a vertical central section of the same; and Fig. 3, the elevation of a
shorter or flat candlestick. In these Figures similar letters of reference
stand for the like parts where they recur. a, glass globe, polished or not, set
& fixed upon the socket 6 by means of two indian-rubber washers k, k, of
another metallic one ; and another socket c, secured on the former by means
of a set screw i. The socket 6 is so grooved through its generating lines, that
each part may act spring-like against the tube d, whereby the socket 6 is held
in its right position on the tube d; d, copper tube, with internal and external
spiral grooves, and liable to move round its axis without any possibility of
rising in the vertical direction, being locked by the washers m & n, fitted to
the upper part of the tube e by a bayonet joint (Figs. 1 & 2); e, metallic tube
soldered or fitted otherwise, at its lower part to the foot or stand r of the
candlestick, and having lengthwise two grooves h, h, which serve to guide the
9, secured to the candle-holder f, which latter is enclosed in the tube e;
(Fig. 4), washers of like form; o, Fig. 1, represents a whole candle; and
Fig. 3, a portion of candle; p, save-all; q, bayonet joint for securing the
save-all on to the candlestick; r, the foot of the candlestick.
rod
m, n
In order to raise the candle as it burns away, it suffices to cause the tube d
to turn; and it will be easily understood, that the ends of the rod g being
engaged in the spirals of said tube, and being guided by the grooves h, the
candle-holder will rise in the vertical direction. By raising the socket b
the globe which surrounds the flame, and shelters it against the action of the
air, is caused to rise. The same improvements are applicable to the candle-
stick represented at (Fig. 3.) To replace the globe, the screw i, the socket c
and the washers j, k, are to be removed. The candle might also be raised
gradually by means of a spiral spring, the action of which should be controlled
by a small chain and clickwork operated by hand.
I have represented in (Figs. 5, 6, 7.) some modifications of the foregoing
arrangements. Fig. 5 shows the front view of a candlestick; Fig. 6, the
globe and its three grooves; Fig. 7, the plan of the small socket provided
with three hooks. In these three Figures the same letters of reference indi-
cate the same parts where they recur. a, foot of the candlestick with the
body b', in the interior of which is lodged the candle; there is shown at c¹ the
vertical slide for raising or lowering the save-all d' provided with a knob e¹,
which passes through the vertical slides c'; d', save-all for raising or lowering
the candle; g', small socket upon which rests the globe; the three hooks are
seen at h¹,;, globe, upon the opening of which are seen the grooves ",

page_text: which are to engage the hooks h¹; k¹, openings in the body b¹, through which
the wick is lighted. The mode of fixation of the globe may be applied to
every description of candlesticks, lamps, &c.; the plate or socket upon which
the globe is secured by a bayonet. joint may also be made with a hinge, &
by a rocking motion of the globe the wick is uncovered, and can be readily
lighted.
Having thus described the nature of my Invention, I desire it to be
distinctly understood, that what I claim as new, and as being of my Invention,
is,―
First, the new arrangements for candlesticks, &c., as described.
Secondly, the various modes of securing the globe thereon, substantially as
described.
In witness whereof, I, the said Edmond Armand Louis D'Argy, have
hereunto set my hand and seal, this Fifteenth day of November, in
the year of our Lord One thousand eight hundred and sixty.
