Year: 1894

page_text: I JACQUES GUIRAUD, of 9 Passage des Eaux, à Paris, in the Republic of
France, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a lantern with weather guard and a helical
reflector forming an alarm.
During movement of the lantern the wind actuates the rotary helical reflector
one of the wings of which carries a striker which at each turn rings a bell.
If it is desired to stop the bell it is sufficient to keep the bell against the lantern
carrier by means of a rubber ring. At the back of the lantern a small opening is
made for the purpose of lighting or extinguishing the candle.
The socket of the lantern is provided inside with a spiral spring continuously
forcing the candle upwards. This socket is closed either by a bayonet joint or by
a screw thread or any other means. In order to obtain greater lightness and less
breakage I replace the lantern glasses by mica sheets as transparent as glass.
A tongue inside the lantern forms a spring to lead the mica into its groove from
the top downwards and serves also to withdraw the mica by pressing with the
finger on the tongue from the bottom upwards.
Dated this 14th day of November 1894.

I JACQUES GUIRAUD, of 9 Passage des Eaux, à Paris, in the Republic of
France, 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 has for its object a lantern with weather guard and a helical
reflector forming an alarm.
This lantern is very light, opposes a very small surface to the wind, illuminates
from its four open faces, supplies an illuminating power of very great intensity,
actuates automatically an alarm bell, and avoids any deposit occasioned by the
use of oil.
In the accompanying drawing,
Fig. 1 represents a perspective view of the lantern, that is to say the complete
lantern with a helix and bell.
Fig. 2 represents the lantern comprising only the weather guard lantern.
During movement of the lantern the wind actuates the rotary helical reflector C
one of the wings of which carries a striker c which at each turn rings a bell d.
If it is desired to stop the bell it is sufficient to keep the bell against the lantern
bracket D by means of a rubber ring e. At the back of the lantern a small
opening at A is made for the purpose of lighting or extinguishing the candle.

page_text: The socket of the lantern is provided inside with a spiral spring continuously
forcing the candle upwards. This socket is closed either by a bayonet joint or by
a screw thread or any other means. In order to obtain greater lightness and less
breakage the lantern glasses are replaced by mica sheets.
A tongue B inside the lantern forms a spring to lead the mica into its groove
from the top downwards and serves also to withdraw the mica by pressing with the
finger on the tongue from the bottom upwards.
A weather guard or air deflecting device consists in forming the lantern narrower
in front than at the rear as shown in Fig. 1.
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:
An air deflecting lamp, with mica squares, provided at the back with a helical
reflector and striker hitting a bell at each revolution substantially as above
described with reference to the annexed drawings.
Dated this 13th day of August 1895.
