AN IMPROVED APPARATUS FOR PRODUCING LIGHT
Year: 1850

page_text: WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain, bearing date at Westminster, the Fourteenth day of November, One
thousand eight hundred and fifty, in the fourteenth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Charles Allemand, my exors, adñors, and assigns, Her especial licence, full
power, sole privilege and authority, that I, the said Charles Allemand, my
exors, admors, and assigns, and such others as I, the said Charles Allemand,
my exors, adors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and, vend, within that part of
Her said Majesty United Kingdom of Great Britain and Ireland called
England, my Invention of "AN IMPROVED APPARATUS FOR PRODUCING LIGHT;"
in which said Letters Patent is contained a proviso that I, the said Charles.
Allemand, should cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed; by an instrument
in writing under my hand and seal, to be enrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after

page_text: the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I,' the said
Charles Allemand, do hereby declare the nature of my said Invention, and
the manner in which the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed, and to the Figures marked
thereon, in which the same letters of reference represent parts which are
similar, that is to say:-
A
My Invention consists in an apparatus for producing light by means of
wax candles having their heads phosphorated, and in the mode of causing
these wax candles to arrive opposite an opening through which they come out,
and also in the rotative motion producing the necessary friction for breaking
the phosphore with which the heads of the wax candles are covered.
represents a rod, around which is permanently fixed a spiral spring kept at
its lower extremity by the cross piece B. The rod A descends in a cylinder
C surrounded by the external tube D, with which it is made to adhere by
being soldered with it upon a plate E, which composes with the large
cylinder F (to which it is soldered), the body of the apparatus. An-
other cylinder G is provided at, top with the catching H composed of a
number of cogs equal to that of the wax candles the apparatus is to con-
tained. That cylinder G revolves round the afore-described cylinder D, and
receives the candle holder J, having an internal bearing which fits in a
slit cut internaly in the cylinder G, and in such a manner that the holder J
appears but one organ with the aforesaid cylinder G, and with which it
always moves. Above the cylinder G, and round the cylinder D, a small
ferrule is set; it is provided with two bearings and a bent spring. The
bearings of the ferrule K pass through the two grooves of the plate E, and
enter in the two slits cut in a ring soldered in the middle of a kind of a lid L
which is fixed to the top of the apparatus. The lid L is provided with a hook
spring which catches with another hook riveted on the plate E, and set close
the opening through which the candles are made to pass. A metallic grater
M, or of any other convenient substance, is either soldered or adapted to the
lid L, close another opening which corresponds to that of the plate E, and
lights the candle at the moment it is to egress through its opening, after having
raised the hook spring herein-before mentioned. The wax candle is made to
leave the holder J by means of the rack N and pinion O, which are both
fixed in the piece P on which the apparatus is set.
To wind the apparatus
it suffices to stretch the spiral spring before the lid L bears on the apparatus

and surrounds-the two bearings of the ferrule. K with the two slits cut in the
ring which is soldered in the middle of it. In that position the lid L cannot
extend further than the space between the two grooves of the plate E.
turning from right to left, the knob set on the top of the lid L, until a resis-
tance is felt, I cause to advance by means of the spring with which the
ferrule K is armed, the holder J. By the same motion the spiral spring is
stretched, which causes the hook spring to catch with the small hook of the
of the plate E. The hook spring advances then its disengaged extremity
above the wax candle, which, being on the point of egressing, raises as soon
as it is acted upon by the rack N. This motion causes the rotative movement
of the lid L, and the grater passing with rapidity on the head of the candle
breaks and lights it. It will be easily understood that the apparatus. can
contain any number of wax candles as it suffices to increase or decrease the
number of cogs of the catching, and, consequently, of the holes with which
the holder J is provided. The apparatus consumes the wax candles by series.
of five to five, more or less, according to the range which is given to the
grater M and to the number of cogs which the catching contains. In-order-
to prevent the holder going back, and thus break through the order according
to which the candles are to be burnt, the said holder J is kept by means of a
permanent spring set on the lower part of the plate E so that it cannot
recede. When the apparatus is to be alimented with wax candles, the holder J
is taken off from the interior of the apparatus by placing its bearing opposite
an empty space prepared purposely in the piece Q, which is soldered on the
bottom of the cylinders C, D, G; the holder is afterwards replaced without
any other precautions. The applications of the apparatus are so numerous
that it is useless to enumerate them.

And having now described the nature of my Invention, and the manner of
carrying the same into effect; I wish it to be understood that I do not confine
myself to the precise details hereunto described provided the general features.
of the arrangements be retained for carrying out the said Invention. But
what I claim as my Invention, and intented to be protected by the said; Letters.
Patent, is,
Firstly, the combination and arrangement of apparatus. for producing..
light, as herein-before described, reference being had, to. the Figures of the-
Drawing.
Secondly, the constructing a wax candle holder and its mode of operating,
as herein-before described, reference being had to the Figures 2, 3, 5, 6, 7, 8,
& 9 of the Drawing.

page_text: Thirdly, the mode of forcing out the wax candles by means of a rack, as
herein-before described, reference being had to the Figures 3, 9, 10, &, 11 of
the Drawing.
In witness whereof, I, the said Charles Allemand, have hereunto 'set
my hand and seal; this Twelfth day of May, in the year of our Lord
One thousand eight hundred and fifty-one.
CHARLES (L.S.) ALLEMAND.
