page_text: I, CHARLES MONPLOT, of 5, Rue de Mazagran, Paris, in the Republio of France,
Engineer, do hereby declare the nature of this invention to be as follows
The present application has for its object to provide an apparatus for lighting
by means of magnesium.
This apparatus, by which it is possible to obtain a continuous and permanent
light, self-adjusting according to necessity, 18 composed of a clockwork move-
ment of suitable kind, combined with an automatic burner, fixed metallic
scrapers for the purpose of removing the magnesium oxide adhering to the sur-
face of the burner, and a cutter formed of four or more brass or iron wie rods,
etc, and intended to cut the magnesium after its issue from the burner
The said apparatus may be enclosed in a metal case of cylindrical or other
form, and terminated at its base in a globe and a receptacle to receive the mag-
nesium oxide produced by the combustion of the magnesium.
The clockwork movement for diving the apparatus consists of a barel and a
certain number of gear wheels From these successive gear wheels, and by
means of bevel pinions, a spindle receives a rotary movement, which it com-
municates to a burner. This burner has a rod passing through a fixed piece,
which canes wires which form a scraper.
The cutter 18 mounted on an axle which receives 1otary motion from the
spindle A vertical fixed 10d 18 placed parallel to the axle of the cutter, and is
intended to carry a small glass nozzle serving as a guide to the ribbon of mag-
nesium after its combustion, and up to its point of issue, where it is severed by
the cutter
This nozzle, by reason of its shape, 18 for the purpose of directing the thread of
magnesium directly, and without hindrance, under the action of the cutter, and
thus preventing the flickering of the light. The magnesium is 1olled on a
bobbin, from whence it passes to the interior of the rod of the burner where the
combustion takes place.
The regulation of the feed of the magnesium 18 effected by means of a regulator
formed of two flexible pallets fixed upon two pieces keyed upon a spindle driven
by the clockwork At the middle of these pallets are fixed two counterweights,
serving as a governor or flyer for the clockwork
Given the flexibility of the pallets in the direction of their rotation the two
pieces fixed on the spindle approach each other, which produces an energetic
action on the clockwork, which is regulated by means of a screw and a lever.
The starting and stopping of the apparatus is effected by a button screwed to a

1, CHARLES MONPLOT, of 5, Rue de Mazagian, Paris, in the Republic of France,
Engineer, 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.
The present application has for its object to provide an apparatus for lighting
by means of magnesium, such apparatus being suitable to use in the lighting of
ailway stations, parks, country banacks, work-yaids, ships, ports of embarca-
tion, quarries, country houses, villas, etc, etc
This apparatus, by which it is possible to obtain a continuous and permanent
light, self-adjusting according to requirements, 18 composed of a clockwork move-
ment of suitable kind, combined with an automatio buinei, fixed metallic
aciapers for the purpose of removing the magnesium oxide adhering to the surface
of the burner, and a rotating cutter formed of four or more biass, iron, or other
wie ods, carried by a cential boss, and intended to cut off the magnesium after
its issue from the buinei
The said apparatus may be enclosed in a metal case of cylindrical or other formi,
and provided at its lower part with a globe, and a receptacle to receive the mag-
nesium oxide produced by the combustion of the magnesium.
In order that my invention may be clearly understood, I have illustrated it in
the annexed diawing, in which.-
-
Fig 1 shews a front elevation of my apparatus, with a portion in section; and
Fig 218 a sectional elevation, as seen from one side
In these two figures, the outer casing, enclosing the apparatus, as well as the
globe and receptacle before mentioned, are not shown, in order that the whole
mechanism may be clearly seen.
Fig 3 shews in plan view the cutter, and
Fig. 4 is a plan view of the burner scrapeis.
The clockwork movement for diving the apparatus may vary greatly, and I
shall therefore confine myself to describing the novel features of it relating to
the regulation of the combustion, as well as to those which apply duectly to the
control of the roller upon which the magnesium passes, and further, to those
features which relate to the buiuer and the cutter
In the various figures, the same reference letters indicate like parts; thus, A
18 a spring banel adapted to drive the clockwork movement in the usual way
From this clock" oik movement, and by means of bevel pinions a, b, a
spindle receives 1otary motion, which it communicates to a burner B, through
the spur geaning de This burner has a hollow 1od or tube B', which passes
through a fixed tubular caner C, supporting wies f,f, which form a sciaper
D is a cutter, mounted on a rod oi axle attached to the spindle c, so that it
receives 1otary motion therefiom.
D is a vertical fixed 10d fitted to the piece h, and parallel to the axle g of the
cutter This rod D is intended to carry a small glasa tube or sleeve t, which

page_text: acts as a guide to the ribbon of magnesium E¹, after its combustion, and up to
its point of issue, where it 18 severed by the cutter D.
This tube or sleeve 18 of special shape, as shown, this special shape serving
to direct the thread of magnesium directly, and without hindrance to the action
of the cutter D, thus preventing the flickering of the light.
E is a bobbin, upon which the magnesium E 18 wound, and from which it
passes to the 1ollei 7, which is duiven by the clockwork movement. Against this
ioller the magnesium strip is constantly held by the 1oller 7', called by an aim
operated by the spring . From these rollers, the strip passes at once to the
interior of the tube B, in order to reach the burner B, where the combustion
takes place
F1s a plate carrying the entire apparatus, the upper enclosing case, and also
the portion F, to which the globe and the receptacle for the magnesium oxide
ale fixed.
Upon one portion of the plate F 18 placed a chimney G, adapted to catch the
smoke evolved by the combustion, and eject it from the apparatus
The regulation of the feed of the magnesium strip is effected by means of a
regulator formed of two flexible pallets n, n, fixed upon two pieces of bosses mm²,
keyed upon a spindle p, and driven by the clockwork At the middle of these
pallets are fixed two counter weights o, o, serving as a governor or flyer for the
clockwork.
Given the flexibility of the pallets n, n, it will be seen that, during their
1otation, the two pieces m, m³, will be caused to approach each other, and produce
an energetic action on the clockwork This action 18 regulated by means of a
screw and a lever r, pivotted at, the extremity 2 of lever r serving as an
abutment for a disc or plate m³, formed in one with the piece m³.
The starting and stopping of the apparatus is effected by a button H, attached
to a piece H¹, and, by means of a spring I, carrying a piece I', which acts as a
brake on the wheel J of the clockwork.
Having thus described my apparatus in its vanous parts, I will now proceed
to describe its operation.
The starting of my apparatus, after the spring barel A has been wound up,
18 effected by pushing up the button H, which puts the clockwork in gear, and
simultaneously rotates the burner B and the cutter D At the same tune, the
holle, which is likewise diven by the same movement, diaws out the mag-
nesium 1ibbon E', which burns as it issues from the burner B, continuing its
descent till the movement when, guided by the nozzle 2, it reaches the end of the
said nozzle, where it 18 severed by the blades of the cutter D.
I would remark that I place the nozzle 1, as well as the cutter D), at a distance
from the burner B, so calculated that the severance of the magnesium takes
place after it has burnt for such a distance from its point of ignition, that it
inay not have any effect on the light, and may not produce any flickering.
The burner B, being movable, the magnesium oxide which adheres to the
face thereof 18 swept off by the wires f,f, fixed to the piece C during the rotation
of the said burner.
To stop the apparatus, it suffices to pull down the button H, to throw the
movement out of gear, and so bing it to a standstill.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim 18.
-
1. The adaptation of a clockwork movement to an apparatus intended to serve
for lighting purposes, or for making luminous projections, and employing mag-
nesium as the illuminating medium.
2 The burner B, rotating within a fixed portion C, carrying the wires f, f, for
the purpose of removing any accumulation of magnesium oxide on the lower face
of the burner.

page_text: 3 The application of a cutter D, of the character described, to cut off the
magnesium we when burnt, and as it issues from the nozzle 2, and, to this
end, arranged at a sufficient distance from the point of ignition of the buiner to
avoid the flickering of the light, and thus obtain a constant light, the magnesium
oxide falling into a suitable receptacle placed beneath the globe
4 The method of regulating the feed of the magnesium, as well as the method
of starting and stopping the apparatus.
