PROVISIONAL SPECIFICATION.
An Improved Artificial Light Reflector.
I, JOSEPH SPENOE GRANT of 4 Recreation Street, Bolton in the County of
Lancaster, Engineer, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to an improved artificial-light reflector and is designed for
use in bed and sick rooms and other places where it is requisite to concentrate
light supplied from coal-gas, and electricity, or from wax night lights or their
equivalents on any given object, such as, a clock, watch, or other articles, and
consists in mounting a polished concaved disc in a metal or other suitable frame
or tube. The frame or tube is secured to a hinged clip for the purpose of attaching
the same to a gas pipe or other fixing or article supporting the light or otherwise,
which also allows of its being altered in position when a full light is required in
The hinged clip allows of the disc and frame or tube being swivelled to
entirely obscure the light from every part of the room except the article it is
concentrated upon. The disc is so constructed that a very small light will brilliantly
illuminate the object it is directed upon, leaving the rest of the room in absolute
darkness.

COMPLETE SPECIFICATION.
An Improved Artificial Light Reflector.
I, JOSEPH SPENCE GRANT of 4 Recreation Street, Bolton, 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 :-
The object of this invention is to illuminate, with the aid of a small flame of gas
or other artificial light, any article, or portion of bedroom or other appartment, and
obscure the remainder of such appartment. To effect this purpose, I employ a
concave reflector of suitable diameter, (and made of silvered glass, or metal) suspended
in a grooved rim of metal, with two projecting ends, to which is attached an arm,
thus forming a hinge, one end of the arm is formed to fit any shape or size of
burner. In order that this invention may be clearly understood, reference is made
to the accompanying drawings in which :-
Fig. 1 represents the invention as applied to an ordinary gas burner. Fig. 2. is
the invention shown in section, in Fig. 2. B is a grooved strip of metal which forms
a circular rim from which the ends D. D. project, A. is the concave reflector held in
the grooved rim B. C is an arm formed from two pieces of metal, and hollowed to
fit any shape or size of buruer, E is a solid rivet with which the two pieces C. are
fastened, F. is a tubular rivet which connects the arm C to the ends of the rim
at D. D. the same forming a hinge, so that B. and A. may be set at any angle, and
if not required as a reflector it can be turned backwards out of the way.
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 1
claim is:-
An improved artificial light reflector, the object of which is to concentrate,
artificial light on any given article, or space in bedroom or other appartment, it can be

page_text: fixed to any burner (gas or otherwise) and capable of being removed or turned out
of gear, without removing from the burner, substantially as herein before described
and shown by the drawings.
