AN IMPROVED DAYLIGHT REFLECTOR
Year: 1884

page_text: I, WILLIAM JOHN BREWER, of No 2 Victoria Mansions, in the city of West-
minster, Civil Engineer do hereby declare the nature of the said invention for
"AN IMPROVED DAYLIGHT REFLECTOR " to be as follows :-
My invention relates to reflectors used generally outside the windows of
buildings in crowded neighbourhoods to reflect the daylight into the interior of
the room.
Whereas the form of daylight reflector at present in general use is usually
placed completely across the upper half of the window and is inclined outwards at
about an angle of 45%; it offers the following disadvantages: A large portion
of the window is completely blocked by the reflector, the reflected light from the
peculiar position of the reflector is usually thrown upon one part only or upon
the ceiling of the room to be lighted and the projection of the reflector outside the
window materially obstructs the light coming to the window below the reflector
and also that to the windows below.
"
My invention consists in so combining a reflecting plate with a suspending frame
that the reflector may be placed in one or both corners of the window opening, and
is capable of universal adjustment of angle so that the light may be reflected in any
required direction or directions into the interior of the room without any serious
obstruction of the window opening or of the natural light admitted there through,
and without any considerable overhang so as not to obstruct the light to windows
below.
My frame is constructed so as to fit in the jambs of the window openings and is
capable of being there affixed. The reflector or reflectors are conveniently suspended
at their upper end or other part by a swivelled joint from the upper part of the
framing or from a projection therefrom, so as to allow the upper end of the reflecting
frame to be slightly inclined outwards. This swivelled joint is conveniently
attached to the frame by a bolt and nut running in a slot so as to be capable of
ready adjustment, To the bottom of each main frame or to the window sill is
attached one or more slotted quadrants according to the number of reflectors used,
and the lower parts of the reflecting plates are fitted with a projecting bolt or bolts
which are guided in these slotted quadrants, and are fixed therein in any required

page_text: position by ordinary thumb nuts or by springs. Without then any alteration in
the position of the upper swivelled joint the reflecting plates may be set in any
required angular position in the corner of the window jamb by adjustment of the
bolts and thumb nuts, or springs sliding in the quadrant. This may rapidly be done
from time to time in the course of the day if desired to obtain the maximum
reflection of light. The reflecting plate so described and placed in the angles of
the window jamb may be either within or outside the window according to
convenience.
I may use any known form or construction of reflecting plates, and may construct
it so that one part is bent at an angle with the other part for double reflection as
desired.

page_text: I, WILLIAM JOHN BREWER, C.E. of N° 2 Victoria Mansions, Westminster
London do hereby declare the nature of my invention for "AN IMPROVED
DAYLIGHT REFLECTOR" and in what manner the samo is to be performed, to be
particularly described and ascertained in and by the following statement:-
My invention relates to reflectors used generally outside the windows of
buildings in crowded neighbourhoods to reflect the daylight into the interior
of the room.
Whereas the form of daylight reflectors at present in general use is usually
placed completely across the upper half of the window, and is inclined outwards at
about an angle of 45°, it offers the following disadventages.
A large portion of the window is completely blocked by the reflector, the reflected
light from the peculiar position of the reflector is usually thrown upon one part
only or upon the ceiling of the room to be lighted and the projection of the reflector
outside the window materially obstructs the light coming to the window below the
reflector and also that to the windows below.
My invention consists in so combining a reflecting plate with a suspending frame
that the reflector may be placed in one or both corners of the window opening and
is capable of universal adjustment of angle so that the light may be reflected in any
required direction or directions into the interior of the room without any serious
obstruction of the window opening or of the natural light admitted there through,
and without any considerable overhang so as not to obstruct the light to windows
below.
My frame is constructed so as to fit in the jambs of the window openings and is
capable of being there affixed. The reflector or reflectors are conveniently suspended
at their upper end or other part by a swivelled joint from the upper part of the
framing or from a projection therefrom, so as to allow the upper end of the reflecting
frame to be slightly inclined outwards. This swivelled joint is conveniently
attached to the frame by a bolt and nut running in a slot so as to be capable of
ready adjustment. To the bottom of each main frame or to the window cill is
attached one or more slotted quadrants according to the number of reflectors used,
and the lower parts of the reflecting (frames) plates are fitted with a projecting
bolt or bolts which are guided in these slotted quadrants, and are fixed therein in
any required position by ordinary thumb nuts or by springs. Without then any
alteration in the position of the upper swivelled joint the reflecting plates may be
set in any required angular position in the corner of the window jamb by adjust-
ment of the bolts and thumb nuts or springs, sliding in the quadrant. This may
rapidly be done from time to time in the course of the day if desired to obtain the
maximum reflection of light. The reflecting plate so described and placed in the
angles of the window jamb may be either within or outside the window according
to convenience.
"
I may use any known form or construction of reflecting plates and may construct
it so that one part is bent as an angle with the other part for double reflection as

page_text: 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. The combination of suspending frame with universal adjustment so that the
light may be reflected in any required direction into the interior of the room
substantielly as described.
2. The combination of reflectors with universal adjustment to permit the
reflectors being fixed at such an angle as not to obstruct the light to windows
below, substantielly as described.
