IMPROVEMENTS IN MAGNESIUM LAMPS
Year: 1885

page_text: I OSCAR NEY of N° 34, Wilhelm Strasse in the City of Berlin and German
Empire, Mechanician & Chemist, do hereby declare the nature of my Invention for
IMPROVEMENTS IN MAGNESIUM LAMPS and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
My invention relates to improvements in magnesium lamps with mechanical
extraction of the magnesia vapors and the gaseous products of combustion from
the consumption space with an automatic device for removing the magnesia
deposited on the burner and for breaking off the ash from the burning magnesium.
Fig. 1 is a vertical longitudinal section of the lamp. Fig. 2 to 6 aro details of
the same.
The vapors generated in burning magnesium in my improved lamp are drawn
off or exhausted with the heated air in the lamp by mechanical power and at the
same time fresh air caused to flow into the lamp in order to facilitate the combustion
of the magnesium.
I attain my said object by setting a ventilator S or other similarly operating
device such as an air pump, an ejector or other equivalent device in operation so
that a strong current of air is produced in the flue, pipe or canal K which will
carry the vapors generated by the magnesium off with it.
This flue, tube or canal K is bell mouthed, passes through a suitable orifice in
the reflector L so that the bell mouthed end of the same is a short distance from
the burning magnesium and is then led through the case D to a point where the
magnesian vapors can be allowed to pass off without disadvantage or if desired the
said vapors can be condensed in a suitable condensor.
The ventilator S is set in operation through the endless worm and. screw wheel a b
or suitable bevil wheels by means of clockwork or gearing of known construction.
The magnesium which is fed through the burner mouthpiece into the con-
sumption space deposits a considerable quantity of magnesia on the mouthpiece.
of the burner and larger or smaller quantities of this magnesia or ash always
depends from the magnesium.
The next object of my said improvements in magnesium lamps is therefore to
attain a regular consumption of the magnesium and overcome the difficulties
hitherto caused by the magnesia deposits and in order to attain this said object

page_text: I employ a two armed lever H which is automatically so operated on by the
clockwork or other equivalent mechanism that the scraper A and slide V are
alternately moved backwards and forwards in their guides so that the magnesia
deposited on the burner B is removed and the magnesia ash m which depends into
the funnel T is broken.
The scraper A (Fig. 4. 5 and 6) consists of a metallic rod A¹ which is guided in
a suitable tube A and is at the one end forked: two platinum wires P are so
strung over or attached to these said lever ends that they will come into snug
contact with the upper and lower surfaces of the burner B and remove any
magnesia adhering to the same.
The slide V (Fig. 2 and 3) consists of a rod V¹ of like construction to A¹ and is
guided in like manner the forked ends of which said rod are connected with each
other by means of a piece of platinum or other suitable wire which said slide can
reciprocate freely in a slot or opening in the funnel T. The opposite end of each
of the said rods A¹ and V₁ are moveably attached to the opposite ends of the
oscillating lever H.
The projecting pins or pegs s of the wheel R, in rotating the same, press at
recurring periods of time against the nose n of the lever H so as to cause the same
to make an oscillating movement.
After the passage of each pin or pegs over the nose n, the spring f will press
the lever H and with it also the scraper A and slide V into their original positions.
The magnesium is fed regularly and automatically forward to the burner B by
means of the clock work or its equivalent.
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 is
1.) In a magnesium lamp, the removal of the vapors generated by the con-
Bumption of the magnesium by means of a current of air produced by mechanical
power substantially as set forth in the foregoing specification and shown in the
accompanying drawing.
2.) In a magnesium lamp, the automatic removal of the magnesia deposited on
the burner and burner mouthpiece by means of the mechanical device A or its
equivalent substantially as set forth in the foregoing specification and shown in
the accompanying drawing..
3.) In a magnesium lamp, automatically breaking off the magnesian ash
adhering to the burning magnesium by means of the mechanical device V or its
equivalent substantially as set forth in the foregoing specification and shown in the
accompanying drawing.
