I RICHARD PAULSON, of Boon Hills, Langwith, in the County of Nottingham,
Engineer, do hereby declare the nature of this invention for IMPROVEMENTS IN
REFLECTING LIGHT FOR THE PURPOSE OF SIGNALING WITH THE HELIOGRAPH AND
AS A SEARCH, INDICATING, OR AN ILLUMINATING LIGHT, to be as follows:-
The object of this Invention for Improvements in reflecting light for the purpose
of Signaling with the Heliograph and as a search, Indicating, or Illuminating
light, is to construct or combine the reflecting surfaces so that the light shall not
be broadly diffused over a large area when reflected a long or short distance (unless
required to be so) but shall be concentrated, thus rendering it possible to search out
illuminate or detect objects at a much greater distance In carrying out this said
Invention into practise, I may, instead of using the ordinary reflector or mirrow,
make use of one or more posessing high magnifying as well as reflecting power,
this lens or mirrow may have a convex or concave surface, or surfaces, be
constructed of metal, of any suitable substances, or have two or more seperate
lenses, one having a concave and the other a convex surface, these may be joined
or combined together, as in field glasses or telescopes and made to reflect by having
one surface burnished or silvered, as in mirrows or looking-glasses-To enable me
to regulate or reflect a further concentrated and more intense light or to a greater
distance, I may combine with the aforesaid magnifying reflectors a plain, tapering
or telescoping tube, which may have a highly burnished or reflecting interior, in
which I may also fix one or more prisms, or other lenses placed therein, the distance
the light is required to be thrown may thus be regulated; A second magnifying or
reflecting surface may also be places at any required angle and preferably at a short
distance in front of the aforesaid reflecting mirrow, so that the rays first striking
on its surface are deflected on to the first mirrow and by it again reflected towards
any point or object,
In applying this Invention as aforesaid to Lighthouses or to the Heliograph
I may instead of using the ordinary lantern or oil lamp, make use of or combine
it with an electric or incandescent light, and instead of altering the angle or the
reflecting mirrows, the signals may be made or indicated by the light itself by it
being made to glow or shine at stated intervals. I may also make use of condensing
lens or a parbolic reflector-The reflector may also be made controllable by means
of suitably arranged electro-magnets acted upon by an electric battery and signals
thus given from a distance.

Illuminating Light.
I RICHARD PAULSON of Boon Hills Langwith in the County of Nottingham
Engineer do hereby declare the nature of my said invention and in what manner
'the same is to be performed to be particularly described and ascertained in and
by the following statement:-
The principal object of this invention is to so construct and arrange the apparatus
used for reflecting purposes so that powerful beams of light such for instance as
the electric search or signalling light, used in military or naval operations, shall
not be broadly diffused but may be concentrated on to a second magnifying or
reflecting surface which may be placed at any required angle and preferably at a
short distance in front of the aforesaid reflecting mirror so that the rays first
striking on its surface are deflected on to the mirror placed at the required angle
and then again reflected towards any required point or object and it will be readily
seen that this mirror which reflects the rays towards the object would be the one
seen and form a mark thereby saving the main mirror and light from being shot at,
and thereby getting damaged while of course the second mirror could be more
readily replaced than the first.
In carrying the aforesaid "invention into practice I make use of one or more
powerful reflectors, so arranged, that although quite as powerful or even more
powerful beams of light can be thrown as required from a second mirror the risk
of the principal part of the apparatus being disarranged or even completely
destroyed should a shot strike it is reduced to a minimum while should the part
necessarily exposed be struck, or damaged, it could be more easily replaced.
In order that the said, Invention may be more fully understood, I now proceed
to describe the same with reference to the drawings herewith annexed.
Fig. show in vertical longitudinal section an application of my invention to
the conning tower of a vessel, or fort.
These figures show clearly the construction of the parts, which will be readily
understood on reference to the following description. A. sliows in section the
position of the reflecting mirror, or surface, which is so constructed and placed as
to focus and concentrate the light on to a second mirrow, lens, reflecting surface (B:)
or combination of the same, froin which it may be thrown in any required direction.
-To enable me to more effectively do this, I may make use of a cone (C) of metal,
highly burnished on its inner sides, so that the rays of light can more readily be
concentrated in the required direction-I do not confine myself to the use of a
single reflecting mirrow, or surface at (A.) as the same may be multiplied and
placed at various angles round the light if required-It must also be understood
that this light together with the reflecting mirrors is so arranged as to be readily
turned in any required direction and thus keep the light constantly on the reflecting
mirror (B) no matter which way it is turned, neither do I confine myself to any
particular class of reflector, lense, or mirror, I may use parbolic or magnifying

page_text: mirrows, my object being to focus the light upon the reflector as strongly as possible
and which enables the parts most liable to damage in action to be placed either in
a shot proof tower or behind the bulwalks of the vessel or other convenient part
-In the drawing I show an arrangement by which the electric, or other light, can
be rotated in any direction it bening pivoted on the hollow bolt (D.) for that purpose;
if desired the cover (E) and also the plate (F.) may be rotated at the same time, by
handles or other means connected therewith, The reflector (B) is also arranged to
move as required.
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
1st. The use of a parbolic or other mirror for first reflecting and a second
mirror or reflector for throwing the light in any required direction and which is
placed at a distance from the first as and for the purposes herein set forth.
