Complete Specification Left, 26th Oct., 1896--Accepted, 28th Nov., 1896
I, BENJAMIN JOSIAS BREARLEY, of Prescot Road, St. Helens, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a simple and inexpensive construction of lamp-
reflectors, that are specially suitable for use in connection with incandescent
electric lamps.
The silvered-glass reflectors hitherto constructed have so far as I am aware, been
made either of conical form in one piece or of several pieces connected together so
as to form a reflector of polygonal section.
Now, according to this invention, 1 employ for a sun or overhead light for
example, a flat disc or sheet of plate-glass, silvered on the back and carried, it may
be, in a depending frame of any suitable material and shape. The disc or sheet
of glass has one or more holes made through it for receiving and carrying an
incandescent electric lamp or a group of such lamps, the electric conductors for
which are connected with the terminals of the lamp or lamps in any suitable
manner behind the reflector as to hide such conductors from sight. In some cases
1 provide these holes with bushes or holders to which the electric conductors are
attached and which are adapted to put the lamps in circuit as soon as they are
placed in position on the reflector.
A reflector of the kind described may in some cases be curved so as to be
suitable for reflecting the light of a group of lamps arranged one above another or
side by side. Such a reflector may be used for the sides of shop windows for
which purpose it may be curved in the direction of its length and have either a
concave or a convex surface to suit special requirements.

I BENJAMIN JOSIAS BREARLEY, of Prescot Road, St. Helens, in the County
of Lancaster, 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 simple and inexpensive constructions of lamp-reflectors

page_text: that are specially suitable for use in connection with incandescent electric
lamps.
The silvered-glass reflectors hitherto constructed have, as far as I am aware,
been made either of conical form in one piece, or of several pieces connected
together so as to form a reflector of polygonal section.
Now, according to this invention, I employ for a sun or overhead light, for
example, a flat disc or sheet of plate-glass, silvered on the back and carried, it
may be, in a depending frame of any suitable material and shape. The disc or
sheet of glass has one or more holes made through it for receiving and carrying
an incandescent electric lamp, or a group of such lamps, the electric conductors for
which are connected with the terminals of the lamp or lamps in any suitable manner
behind the reflector so as to hide such conductors from sight. In some cases
I provide these holes with bushes or holders to which the electric conductors are
attached and which are adapted to put the lamps in circuit as soon as they are
placed in position on the reflector.
A reflector of the kind described may in some cases be curved so as to be
suitable for reflecting the light of a group of lamps arranged one above another
or side by side. Such a reflector may be used for the sides of shop windows, for
which purpose it may be curved in the direction of its length and have either a
concave or a convex surface to suit special requirements.
The accompanying drawings illustrate various forms of sun or overhead
reflectors according to this invention.
Fig. 1 is an underside view and Fig. 2 a cross section of a circular reflector.
provided with five lamps;
Figs. 3 and 4 are cross sections of reflectors similar to that shown in Figs. 1
and 2 but having convex and concave reflecting surfaces respectively;
Fig. 5 is a side elevation and Fig. 6 an end view of a reflector that carries a
number of lamps placed in line and has a convex reflecting surface;
Fig. 7 is an end view of a reflector similar to that shown in Figs. 5 and 6 but
having a concave reflecting surface.
The reflector in each of the forms shown consists of a silvered shoet of plate-
glass 1 through which holes are formed for receiving holders 2 for incandescent
electric lamps 3; these holders which may be of any known and suitable form are
held in position by any convenient means such as screw-threaded nuts 4. The upper
or rear end of each lamp holder is slightly enlarged or flanged as shown at 2 to
rest on the wooden backing 5 which forms the supporting frame for the reflector
and to it are connected the conducting wires 6.
In the forms shown in Figs. 3 and 6 the backing 5 may be in the form of cross
pieces instead of a solid board 5. The frame carrying the reflector may be
provided with supporting chains not shown.
The lamps, when a number are attached to one reflector, may be connected so
that the whole may be in one circuit and worked from one switch or otherwise
according to requirements.
It will be seen that the shape of the reflecting surfaces shown in Figs. 3 and 6
is such as to distribute the rays of light, whilst those shown in Figs. 4 and 7 is
such as to concentrate them either to a focus or otherwise.
The reflecting surface of the glass may either be quite plain or be ribbed
checkered, or otherwise figured.
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. A lamp-reflector comprising a sheet of glass having one or more holes
through it adapted to receive and carry an incandescent electric lamp or a group
of such lamps and admit of the conductors being located behind the reflector
substantially as described with reference to the drawings.
2. Lamp-reflectors constructed as hereinbefore described with reference

page_text: respectively to and shown in Figs. 1 and 2; in Fig. 3; in Fig. 4; in Figs. 5 and 6
and in Fig. 7 of the accompanying drawings.
