I ILLIUS AUGUSTUS TIMMIS of No. 2 Great George Street, Westminster
London S.W. Civil Engineer do hereby declare the nature of this invention to
be as follows:-
The objects of my invention are
First To shade the electric light itself whether arc or incandescent from the
eyes of those who see or use it.
Secondly To reflect the maximum amount of light so that

With these objects in view I shade the electric light are or incandescent by
grinding or dipping the glass bulb or shade or in any suitable or convenient way
and thus prevent the light itself falling on the human eye but by putting a glass
mirror or reflector as described in Patent No. 180108 (glass silvered at the back)
above or at the back of the electric lamp I practically reflect the maximum of the
light where it is required. The combination of shading the light when made (at
the point of the arc or incandescence) with a glass mirror is the object I have to
carry out.

COMPLETE SPECIFICATION.
Improvements in the Reflection and Distribution of the Electric
Light.
I, ILLIUS AUGUSTUS TIMMIS of No. 2, Great George Street, Westminster
London S. W. Civil 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 objects of my invention are
First To shade the electric light itself whether arc or incandescent from the
use of those who see or use it.
:-
Secondly To reflect the maximum amount of light so that it may be used
where wanted.
With these objects in view I shade the electric light arc or incandescent by
grinding or dipping the glass bulb in any suitable or convenient way and thus
prevent the light falling on the human eye but by putting a glass mirror or reflector
as described in Patent No. 18,010 (glass silvered at the back) above or at the
back of the electric lamp I practically reflect the maximum of the light where it
is required. The combination of the shading of the light when made (at the
point of the arc or incandescence) with a glass mirror is the object I have to
carry out.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 of the drawing represents an incandescent lamp in combination with a
reflector. a being the incandescent lamp. The bottom part of the bulb being
ground or shaded to prevent the light falling on the human eye. b is the reflector
(glass silvered at the back) described in my Patent No. 18010. c is the ordinary
incandescent lamp holder. The top part of this holder c is provided with a screw

page_text: end d engaging with the three armed support e which rests on the back of the
reflector b. At the top of the bulb of the incandescent lamp a on the convex
side of the reflector I provide a collar f affixed to the collar on the lamp. This
collar keeping the holder c and support e in their respective places. Of course
it will be understood that any other arrangement can be used which will keep the
bulb of the incandescent lamp close up to the convex side or the reflector.
In applying the invention to arc lamps, it is preferable to select only those in
which the arc is maintained at a constant height.
Fig. 2, illustrates the application of my invention to an arc lamp. The lower
carbon, holder is provided with a glass globe G, the lower half of which is ground,
or shaded.
A silvered glass reflector a¹ is attached by chains 6' or other suitable means to
the under-side of the casing c containing the regulating device which controls the
progress of the carbons.
If the arc is not maintained at a constant height, the reflector may be attached
to the holder of the movable carbon.
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 I
claim is-
The combination of a shade to an arc or incandescent electric lamp together
with a glass silvered mirror substantially as, and for the purposes hereinbefore
described.
