County of Middlesex Builder for an Invention of "IMPROVEMENTS IN
REFLECTING PAVEMENT AND OTHER SIMILAR LIGHTS,"
PROVISIONAL SPECIFICATION left by the said William Brass at the Office
of the Commissioners of Patents on the 2nd March 1882.
WILLIAM BRASS Junior of Old Street St Lukes in the County of Middlesex
Builder. "IMPROVEMENTS IN REFLECTING PAVEMENT AND OTHER SIMILAR
LIGHTS
"
This invention relates to improvements in pavement, stall board, coal plate and
other similar reflecting lights and has for its object the conveyance of daylight by
reflection into long dark basements vaults areas and other dark places by means of
improved arrangements of reflectors or reflecting surfaces.
These improved lights consist of a metal or other frame filled in with crystal
plate or other suitable glass combined with reflectors suspended and arranged
underneath provision being made for ventilation.
My improved reflector advantageously consists of a frame which is fitted to the
underside (or inside) of the pavement stall board coal plate or other similar light.
These improved reflectors are hung on centres and are fitted so as to allow of
their being readily adapted to ordinary pavement lights.
They are either fixed or are capable of adjustment in order that they may be
adjusted and fixed at any desired angle by means of a connecting bar and lever or
otherwise (similar to a series of louvres) to suit any length of basement.
The reflector frames are glazed advantageously with fluted glass silvered on the
back and fixed horizontally or vertically as required. The backs of these reflectors
are advantageously protected by plain sheet glass firmly bedded in the frame.
In place of suspending the reflector frames on horizontal axes they may be
mounted on vertical axes below the pavement or other similar light.
By my improved arrangement and construction of reflectors in combination with
pavement lights the light is distributed over a much larger area and with greater
brilliancy

My invention relates to improvements in pavement stall board coal plate and
other similar reflecting lights and has for its object the conveyance of daylight by
reflection (which is obtained by my improved and simplified mechanical arrange-
ment thereof) into long dark basements vaults areas and other dark places by
means of improved arrangements of reflectors or reflecting surfaces.
These improved lights consist of a metal or other frame filled in with crystal
plate or other suitable glass combined with reflectors suspended and arranged
underneath.
My improved reflector advantageously consists of a frame which is fitted to
the underside (or inside) of the pavement stall board coal plate or other similar
light.
These improved reflectors are hung on centres and are fitted so as to allow of
their being readily adapted to ordinary pavement lights being capable of adjust-
ment in order that they may be adjusted and fixed at any desired angle by means
of an improved connecting bar and lever or otherwise similar to a series of louvres
to suit any length of basement.
The reflector frames are glazed advantageously with fluted glass silvered on
the back and fixed horizontally or vertically as required. The backs of these
reflectors are advantageously protected by plain sheet glass firmly bedded in the
frame.
By my improved arrangement and construction of reflectors in combination with
pavement lights the light is distributed over a much larger area and with greater
brilliancy than heretofore.
And in order that my invention may be clearly understood and readily carried
into practice I will proceed to describe the drawings hereto annexed.
Figures 1 and 2 show vertical sectional perspective views of a basement having
my improved reflecting pavement lights applied thereto.
In Figure 1 the reflectors are represented as out of use and in Figure 2 as
in use.
Figure 3 shows a perspective view of my improved arrangement of reflecting
lights as applied to an iron glazed grating with a series of reflectors a attached to
the underside.
The reflectors a, a, are made advantageously with a highly polished silvered surface
(weather proof) which is waved or fluted and attached to the grating b in such
manner that the angle of reflection can be adjusted to suit the position in which

connecting rod or stay c secured by a small lock nut.

a larger scale and
The series of reflectors a are advantageously graduated in width as shown.
Figure 4 shows a vertical section of my improved arrangement of reflectors as
applied to pavement and stall-board lights combined. a a are the reflectors hung
on centres d and e are adjusting rods and quadrant and f suspending rods.
Figure 5 shows a vertical section of my improved arrangement of reflecting lights
also as applied to pavement lights and stall board combined without bulkhead
obstruction a a are the reflectors d and e adjusting rods and quadrant and ƒ the
suspending rods.
Figure 6 shows a vertical section of my improved reflecting lights as applied
to a series of glazed steps and landing combined a a are the reflectors hung on
centres b b glass risers c c glass treads and d and e adjusting rods and quadrants.
Figures 7 and 8 show my improved arrangement of reflecting lights as applied
and adapted to cellar flaps and rolling ways. Figure 7 represents cellar-flaps closed
with reflectors in action and Figure 8 represents cellar flaps open with the
reflectors a a out of action and moved out of the way. a a are the reflectors
d and e adjusting rod and quadrant f the suspending rods. 9 cord for pulling
reflectors a a into position, h cord for pulling reflectors out of position.
Figure 9 shows a vertical section of my improved reflecting lights as applied to
a sky light for reflecting daylight into apartments where no side or window light is
available. a a are the reflectors d and e the adjusting rod and quadrant and ƒ the
suspending rods.
Figure 10 represents a perspective view of a vault or cellar and a path or road-
way used as a lavatory or other purpose and illuminated by a glazed coal plate
from which is suspended a sexangular reflector a a made of silver fluted glass
highly polished for diffusing daylight which reflector also forms a gas shade
reflector to the gas burner d having silvered glass b inside as well as that
outside.
Figures 11 and 12 represent the plan and section of my improved illuminating
and ventilating coal plate.
I would remark that I am aware that silvered reflectors are not new others
having previously endeavoured to bring such reflectors into use in combination
with pavement and other lights but have hitherto failed owing to their complicated
arrangements which were costly and required skill in using them whereas my
improved combination and arrangement of such reflecting lights are both simple
and effective combined with strength and cheapness.
I make no claim to any of the parts separately which are well known and in
common use But what I claim is :-
First, The improved arrangement and construction of the series of reflectors a a
of different depths arranged in succession the back or hindmost of the series being
the deepest the reflectors a being mounted so as to be capable of adjustment to
different angles substantially as and for the purpose herein before described and
represented in the drawings hereto annexed.
Second. I claim the improved arrangement and combination of a series of
reflectors such as a a adapted to and arranged in combination with pavement and
stall board lights skylights and other openings through which daylight is admitted
such reflectors being capable of adjustment by mechanism so as to reflect and
diffuse the light into basements and other dark places substantially in the manner
and for the purpose hereinbefore described with reference to Figures 1-2-3-3a
3b 4-5-6-7-8-9 and 10 of the drawings hereto annexed.
Third. I claim the improved arrangement and combination of reflecting pave-
ment and other similar lights constructed and arranged so as to act substantially in

page_text: the manner and for the several purposes hereinbefore particularly described and
represented in the drawings hereto annexed.
In witness whereof I the said William Brass Junior have hereunto set my
hand and seal this first day of September in the year of our Lord one
thousand eight hundred and eighty two.
