PROVISIONAL SPECIFICATION.
An Improved Method of Street Lighting by Glow Lamps, by Using
Reflectors Set at Different Angles to one another.
I, HORACE LOUIS PETIT BOOT, of The Town Hall, Tunbridge Wells, Kent
Boro' Electrical Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to using for street, or public lighting of any description,
one or more lamps in front of a silvered glass reflector of special construction,
or other suitable material. The reflector to be made in such a manner as to
multiply the amount of light, as well as reflect it, the former being obtained by
dividing the reflector into pieces, which pieces are to be set at different angles to
each other, & the lamp, or lamps to be placed in such a position that the optical effect
of seeing it, or them in each piece of reflector is simultaneously produced. The
apparatus may, or may not be used in a suitable lantern.

An Improved Method of Street Lighting by Glow Lamps, by Using
Reflectors Set at Different Angles to one another,
I HORACE LOUIS PETIT BOOT The Town Hall Tunbridge Wells Kent 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 an improved reflector of special construction and which
may be made of silvered glass or other suitable material and is of such a shape
as to multiply the amount of light as well as reflect it the former being obtained
by dividing the reflector into pieces, which pieces are to be set at different angles
to one another and the lamp or lamps to be placed in such a position that the
optical effect of seeing a lamp or lamps in each piece of reflector is simultaneously
produced.
The apparatus may or may not be placed in a suitable lantern.
In order that my invention may be fully understood I will now refer to the
annexed drawings in which :-
Figure 1 is a perspective view of my form of reflector.
Figure 2. Front view of a reflector.
Figure 3. Side view of same.
Figure 4. Cross section through line x-y in Figure 3.
The reflecting material is formed in flat plates a which are carried in a suitable
form of support or casing b; the said plates a being set at the required angle

page_text: with regard to one another as shown in Figure 4. The part c is also of reflecting
material and is bent or corrugated as shown.
The lamp or the like will occupy about the position shown by the dotted lines d
the whole being suitably formed and carried upon a frame or support e. f are
the supports which carry the lamps which in this case are of the incandescent
form but of course any convenient source of illumination may be employed and
the number of lamps and reflectors varied to suit the circumstances in which the
same is used.
The corrugated part of the mirror is formed of plates of reflecting material and
may consist of three plates set at the required angle as shown in the drawings.
The reflecting plates may be secured by the bent clipping pieces g and if desired
the said corrugated plates c may be curved.
It will be seen that owing to the angles at which the mirrors are set, that a
reflection of the light will be seen in each of the plates thus greatly encreasing
the efficiency of the lamp owing to the increased reflection from same.
This invention is particularly applicable to street lamps, and the like and when
desired the mirrors or reflectors may be enclosed in a casing or lantern body.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A new or improved reflector for lamps having a number of reflecting surfaces
set at a desired angle with one another for the purpose of increasing the reflecting
power of the mirror in combination with a gas or electric lamp, substantially as
described and illustrated.
