page_text: I, GASPARE MINISINI of Corso Oporto 31, Turin, Italy, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a magnesium lamp which I shall describe referring to
the accompanying drawings.
Fig. 1 is an elevation and Fig. 2 a side view of a lamp according to my
invention ;
Fig. 3 is a vertical section on the line Z Z of Fig. 4 looking in the direction of
the arrows in Fig. 4 which is a side view of the framework and gearing.
Fig. 5 is a rear view of the lamp open.
Figs. 6 and 7 shew a lantern in which the magnesium lamp is arranged.
The lamp H is of flat oval form, its front A is pivotted on a screw C and fixed
by a screw B, on unscrewing which it can be turned to the position indicated by
dotted lines A¹ giving access to the winding key D and the stop a¹. A cover G
carries the burner F. The framework consisting of two plates I K connected by
3 struts J, contains the clockwork, L the prime arbor on which the spring barrel I.¹
is free and a ratchet wheel Mo is fixed, its teeth engaged by a pawl 6 pivotted
at bo and pressed by a spring b₁. Behind the barrel is a wheel M gearing with
pinion on arbor N having wheel P gearing with pinion R on arbor Q carrying
wheel S gearing with pinion V on arbor U, and on this is a wheel X gearing with
the last pinion y on the arbor Y which carries the flyer Z. At aº is an arm a¹
connected to the interior arm a which can be turned by a¹ so as to meet the flyer
and stop the movement. On the arbor Q outside the plate K is fixed a roller
slightly grooved, against which a disc d free to turn on pivot e is pressed by a
lever a spring i pivotted at 7 has its one end bearing against one of the
struts J, and its other against the lever ƒ thus pressing the disc d against the
roller T.
The magnesium strip is wound spirally on the free roller in the space between
the cover G and the internal framework. The end of the strip is passed between T
and d then between guides m m³ and through the burner F.
In order to use the lamp, the cover A is turned to the position A', the key D is
turned to wind the clockwork, the stop a¹ is moved to release it, and the magnesium
at F is kindled. The lamp is extinguished by moving a¹ so as to stop the clock-
work. As shewn in Figs. 6 and 7 in a portable lantern A, containing an oil or other
lamp n with bent wick tube u and flame o, is placed the magnesium lamp H with
its burner F bent over so that the magnesium is lighted by the lamp flame. Under
the burner is a funnel r which catches the magnesia from the flame into a
receptacle q. At the back of the lamp is a reflector p which can be turned
back to the position p¹ indicated by broken lines at Fig. 6, and s is a hole giving
access to wind and start the clockwork without having to open the lantern.

page_text: I, GASPARE MINISINI, of Corso Oporto 31, Turin, Italy, 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 :-
This invention relates to a magnesium lamp which I shall describe referring to
the drawings accompanying my Provisional Specifiation.
Fig. 1 is an elevation, and Fig. 2 is a side view of a lamp according to my
invention;
Fig. 3 is a vertical section on the line Z Z of Fig. 4-looking in the direction of
the arrows in Fig. 4 which is a side view of the framework and gearing.
Fig. 5 is a rear view of the lamp open.
Figs. 6 and 7 shew a lantern in which the magnesium lamp is arranged.
The lamp H is of flat oval form, its front A is pivotted on a screw C and fixed
by a screw B, on unscrewing which it can be turned to the position indicated by
dotted lines A' giving access to the winding key D and the stop a¹. A cover G
carries the burner F. The framework consisting of two plates I K connected by
3 struts J, contains the clockwork, L the prime arbor on which the spring barrel L¹
is free and a ratchet wheel Mo is fixed, its teeth engaged by a pawl b pivotted
at bo and pressed by a spring b. Behind the barrel is a wheel M gearing with
pinion on arbor N having wheel P gearing with pinion R on arbor Q carrying
wheel S gearing with pinion V on arbor U, and on this is a wheel X gearing with
the last pinion y on the arbor Y which carries the flyer Z. At aº is an arm a¹
connected to the interior arm a which can be turned by a so as to meet the flyer
and stop the movement. On the arbor Q outside the plate K is fixed a roller
slightly grooved, against which a disc d free to turn on pivot, e is pressed by a
lever a spring i pivotted at has its one end bearing against one of the
struts J, and its other against the lever thus pressing the disc d against the
roller T.
The magnesium strip is wound spirally on the free roller h in the space between
the cover G and the internal framework. The end of the strip is passed between T
and d:then between guides m m' and through the burner F.
In order to use the lamp, the cover A is turned to the position A¹, the key D is
turned to wind the clockwork, the stop a' is moved to release it, and the magnesium
at F is kindled. The lamp is extinguished by moving a¹ so as to stop the clock-
work. As shown in Figs. 6 and 7 in a portable lantern A, containing an oil or other
lamp n with bent wick tube u and flame o, is placed the magnesium lamp H with
its burner F bent over so that the magnesium is ligated by the lamp flame. Under
the burner is a funnel which catches the magnesia from the flame into a
receptacle 9. At the back of the lamp is a reflector P. which can be turned
back to the position indicated by broken lines at Fig. 6, and s is a hole
giving access to wind and start the clockwork without having to open the
lantern.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
--
1. A magnesium lamp constructed and operating, substantially as described and
illustrated by the drawings.

page_text: 2. The combination of a magnesium lamp such as is above referred to with an-
oil or other lamp, substantially as described.
