Improvements in Illuminating by Reflected Light Transparent In-
dicators bearing the Names of Streets and Public Places; also
applicable to Advertising Purposes.
We, WILLIAM BLEAKLEY, of 119, Burt Terrace, Gateshead, in the County of
Durham, Commercial Traveller, and JOHN WESTON JORDAN, of Horsley Wood-
house, near Derby, Engineer, do hereby declare the nature of said invention to
be as follows:-
This invention relates to improvements in means of utilising for illumination
a portion of the rays reflected from a light or lights, already serving other
illuminating purposes, or which may be entirely devoted to illuminating according
to this system and, although adapted in various forms to other applications, it
is specially designed for indicating at night the names of streets, squares or
public buildings or the like upon transparent tablets (attached to street lamps)
by the reflected light of such lamps, such light being either of oil gas or electricity
and we will therefore describe it as so applied.
To one side of the lamp is attached to the lantern-frame, a projecting framed
box two opposite sides of which are glazed with the name of the street square or
public building, in distinct letters either clear on a coloured ground or vice versa,
the top, bottom and one end of said box being closed with silvered or other
reflecting surfaces and the end next the lamp glazed with clear glass. Opposite
this end, within the lamp, is mounted on the burner a circular lens, coincident
with the centre of the light and so adjustable as to direct, concentrate, and
intensify the rays of light along the framed box from the top, bottom and further
end of which they are reflected, as from mirrors, and shew brilliantly on the
two transparent sides the letters indicating the name inscribed thereon. In
daylight the name of the street, square or public building is equally displayed
on the transparent tablet sides.
In other modified arrangements always comprising a framed and glazed box
(or light chamber), fitted with mirrors to reflect light, projected into the interior
by a lens (or lenses) and having the advertising matter on one (or both) sides of
the glazed box, this invention may be applied to advertising purposes in fronts
of shops, where reflected light is available, from oil, gas or electric lamps which
may already be serving illuminating purposes or may be specially fitted for
illuminating and displaying according to this invention.
This invention is applicable to existing lamps by suitable connection of the
illuminated box to the frame of the lantern, or to new lamps by the said box
forming part of the original construction of the lantern.

We, WILLIAM BLEAKLEY, late of 119, Burt Terrace, Gateshead, in the County
of Durham, but now of 3, Lois Avenue; Lenton, in the County of Nottingham,
Commercial Traveller, and JoHN WESTON JORDAN, of Horsley Woodhouse, near
Derby, Engineer, 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 improvements in means of utilising
a portion of the
rays of a light or lights already serving other illuminating purposes, or the whole
of the rays of a light or lights, for the illumination of transparent indicators,
and although adapted in various forms to other applications, it is specially
designed for indicating at night the names of streets, squares, public buildings,
or the like upon transparent tablets (attached to street-lamps) by the reflected
light of such lamps, such light being either of oil, gas, or electricity, and we
will therefore first describe it as so applied.
To one side of the lamp is attached to the lantern-frame, a projecting framed
box two opposite sides of which are glazed with the name of the street, square, or
public building in distinct letters, either clear on a coloured ground or vice versa,
the top and bottom of the said box being closed with silvered or other reflecting
surfaces and the end next to the lamp glazed with clear glass. The end remote
from the lamp may also be closed with a silvered or other reflecting surface or be
glazed and carry the name of the street or the like or an advertisement like the
sides, or the two sides of the box may meet together in an edge. Opposite the
inner end of the box and within the lamp or lantern is mounted on the burner
a circular lens adapted and arranged to direct the rays of light that fall upon
it, along the framed box, from the top, bottom, and, it may be, further end of
which they are reflected, as from mirrors, and shew brilliantly on the two trans-
parent sides, and, it may be, the further end, the letters thereon. In daylight
the name of the street, square, or public building is equally displayed on the
transparent-tablet sides.
This invention is applicable to existing lamps by suitable connection of the
illuminated box to the frame of the lantern, or to new lamps by causing the
said box to form part of the original construction of the lantern.
In other forms this invention may be applied to advertising purposes in fronts
of shops, where reflected light is available, from oil, gas, or electric
lamps, which may already be serving illuminating purposes or may be specially
fitted for illuminating and displaying according to this invention.
Figs. 1 to 7 inclusive of the accompanying drawings represent an example of
apparatus according to this invention for utilizing a portion of the rays of the
light of a street-lamp for the purpose mentioned: Fig. 1 is a side elevation of
the entire apparatus; and Figs. 2 to 6 inclusive, which are drawn to a larger
scale than Fig. 1, represent the box alone, Fig. 2 being a side elevation, Figs. 3
and 4 elevations taken from opposite ends, Fig. 5 a transverse vertical section,
Fig. 6 a longitudinal vertical section, and Fig. a sectional plan.
To the frame 1 of the lamp 2 there are secured two cheeks 3 each having a vertical
face and a mushroom-headed screw 4. 5 is a metal box-frame which is pro-
vided with two sheet metal side pieces 6 each having a key-hole 7 for engaging
with the corresponding screw 4. The two sides of the box are closed by trans-

by metal sheets lined with silvered glass 10 and
glass sheet 11 fits in grooves 12 formed by the metal frame 5, and
the arrangement is such that after lifting it out of its grooves, the tablets S
can be withdrawn for cleaning or any other purpose. The end nearer the
lamp is closed by a framed sheet of plain transparent glass 13, which fits in
grooves 14 of the frame 5, whence it can be lifted when desired.
lens, which is supported by a stem 16 from the burner-pipe 17 with its axis
coincident with the centre of the flame of the lamp and so arranged that the
rays falling upon the lens are directed by it along the box. Instead of making
the box rectangular in plan, as shown in full lines, it may be made triangular
in plan, as indicated in dotted lines in Fig. 7 or of any other suitable form.

Figs. 8, 9, and 10 are respectively a longitudinal vertical section, a transverse
vertical section, and a sectional plan representing an example of apparatus ac-
cording to this invention for advertising in front of a shop. In this case the
apparatus comprises a box resembling that shown in Figs. 1 to 7 inclusive but
containing and adapted for a lamp 18. In this case, therefore, the bottom of
the box is provided with a perforated portion 19 to admit air to support com-
bustion and with an outlet 20, furnished with a cowl 21, for the egress of the
products of combustion. The sides of the box are closed, as in the apparatus
shown in Figs. 1 to 7, by transparent tablets S, and both ends of the box are
closed in this case by silvered glass sheets 22. Instead of closing the outer
end of the box with a silvered glass sheet 22, however, it may be closed by a
lettered transparent tablet like the sides. The box may be secured by means of
the holes and suitable mushroom-headed screws in any suitable position, as
over the shop-door.
It will, of course, be understood that although we have shown a box as
provided with only one lamp, such boxes may be adapted for and contain more
than one lamp, and that instead of employing a box containing a lamp or lamps
for advertising outside shops, there may be employed for this purpose a box such
as that shown in Figs. 2 to 7 and arranged to utilize a portion of the rays from a
light or lights used also for other illuminating purposes.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. For utilizing a portion of the rays of a light serving also for other
illuminating purposes for the illumination of transparent indicators, the com-
bination, with the light, of a lens and a reflecting box having transparent sides,
substantially as hereinbefore described.
2. Means for illuminating transparent indicators constructed and arranged
substantially as hereinbefore described with reference to and shown in Figs. 1
to 7 inclusive, or in Figs. 8, 9, and 10 of the accompanying drawings.
