PROVISIONAL SPECIFICATION.
An Improved Electric Arc-light Reflector.
I, CHARLES MORRIS BOLLES, of Dallas, Texas, U.S.A., Real Estate Broker,
do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of electric arc-light lamp which is sus-
pended within a conical-shaped hood to protect the lamp from the weather and,
in a measure, to act as a shade.
The object of this my invention is to provide a simple detachable shade whereby
that portion of the light which formally entered the hood, and also the rays
which passed upwards past the edge of the hood and were consequently wasted,
are reflected by a suitable reflector, of larger diameter and nearer to the light
than the hood; towards the ground; the result being a great increase in the
illumination.
The invention comprises an inverted saucer-shaped reflector having a central
aperture through which the loop-shaped armis or rods, carrying the carbons and
globe, can pass upwardly to a hook depending from the apex of the conical hood,
and by which the lamp is suspended.
An annular band projects vertically upwards from the reflector, and has
another band-made in sections-hinged to its upper edge. This band is of
narrower diameter at its upper edge than at its lower edge which is hinged to
the fixed band. Being made in sections, the upper or hinged band is capable
of being fastened around the lower portion of the hood, by suitable clasps, to
secure the reflector in place just above the light.
The wires to supply the current pass between the hinged sections of the upper
band.

I, CHARLES MORRIS BOLLES, of Dallas, Texas, U.S.A., Real Estate Broker,
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 that class of electric arc-light lamp which is sus-
pended within a conical-shaped hood to protect the lamp from the effects of the
weather.
The object of this my invention is to provide a simple detachable shade whereby
that portion of the light which formerly entered the hood, and also the rays which
passed upwards past the edge of the hood and were consequently wasted, are
reflected by a suitable reflecting surface, of larger diameter and nearer to the light

page_text: than the hood, towards the ground; the result being a great increase in the illumi-
nation.
Reference being had to the drawings hereunto attached:-
Fig. 1 is a sectional elevation of my improved shade; the hood covering the lamp
mechanism being indicated in broken lines.
Fig. 2 is a plan of the shade ready for attachment to the hood.
Fig. 3 is a sectional elevation shewing my improved shade or reflector attached
to the hood of an electric arc-lamp.
My invention comprises a suitably shaped shade 1 having a central aperture 2,
to permit the passage therethrough of the casing 3 of the lamp mechanism, and
slots 4 to enable the shade to be drawn over the hangers 5. An annular band 6
projects upwardly from the shade and has another band-which consists of two
or more parts 7,hinged thereto as shewn at S. The parts 7 converge towards
their upper edges to adapt themselves to the lower part of the hood 9. Clasps or
like suitable means 10 are provided to fasten the parts 7 together around the hood.
A space 11 between the meeting ends of the parts 7 permit the cables 12 to be in-
serted therethrough to the lamp mechanism."
.
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:-
A reflector for electric arc-lamps consisting of a shade, an annular band project-
ing upwardly from the upper surface of the shade, a second band converging towards
its upper edge and comprising two or more parts hinged to the firstmentioned band
and adapted to be secured around the lower part of the hood of an electric arc-lamp
by means of clasps or like means, substantially as and for the purpose herein before
set forth and illustrated in the drawings hereunto annexed.
