PROVISIONAL SPECIFICATION.
Improvements in Reflectors.
I ERNST BÖHM of No. 6 Stonefield Street Islington in the County of Middlesex,
Glassblower and Electrician, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in reflectors and particularly to those
which are used for reflecting daylight into passages, warehouses, offices and apart-
ments generally. with the object of projecting more light into the apartment than
is done by the ordinary glass or metal reflector.
It consists in the combination within a suitable frame of any size and shape and
upon a foundation of metal, wood or other suitable material, of series of glass tubes
silvered inside and arranged in parallel rows near or in actual contact with each
other, or the tubes may be arranged in concentric circles, such tubes being straight
or curved and of any suitable section or shape.
The silvered glass tubes may be fixed on to their foundation or support by
cementing or in any suitable way and the frame or support may be fixed
permanently at such angle as may be found best for projecting light into the apart-
ment, or be provided with means of altering the angle at pleasure.
A reflector thus made receiving the light upon a large portion of the circumference
of each silvered glass tube will be able to project more light than the ordinary wavy
construction of surface with greater brilliancy, further, it may easily be kept clean
and its parts readily replaced in cases of breakage.
When it is desired to reflect from both sides of the reflector, the silvered glass
tubes will not be fixed upon a foundation but supported by wires or otherwise within
the frame.
Dated this Fifth day of November 1892.
COMPLETE SPECIFICATION.
Improvements in Reflectors.
I, ERNST BÖHM of No. 6 Stonefield Street, Islington, in the County of Middlesex,
Glassblower and Electrician, 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 :---
My invention relates to improvements in reflectors and particularly to those which
are used for reflecting daylight into passages, warehouses, offices, and apartments
generally, with the object of projecting more light into the apartment than is done
by the ordinary glass or metal reflector.
It consists in the combination within a suitable frame of any size and shape and
upon a foundation of metal, wood or other suitable material, of series of glass tubes
silvered inside and arranged in parallel rows near or in actual contact with each
other, or the tubes may be arranged in concentric circles, such tubes being straight
or curved and of any suitable section or shape.
In applying my invention for reflecting artificial light such as that from
incandescent lamps, the frame may be made of a box section having four or more
sides and the tubes arranged in longitudinal or transverse parallel rows.

page_text: On the accompanying sheet of drawings I have illustrated by way of example an
application of my invention to a daylight reflector,
Figure 1 being a front view or elevation of a reflector constructed according to my
invention. Figure 2 a longitudinal section through the same. Figure 3 a vertical
section thereof.
Figure 4 a front elevation of a reflector showing the tubes arranged in concentric
circles.
Figure 5 a front elevation of a reflector adapted to suit an incandescent lamp,
and Figure 6 a longitudinal section through the same.
A is the frame. B the foundation or back of same. C the silvered tubes.
D grooves or channels formed in frame A to receive tubes C.
E cement or other plaster for closing ends of tubes.
F plate for securing tubes in grooves or channels.
G metal wire or support for tubes.
The silvered glass tubes may be fixed onto their foundation or support by cementing
or in any suitable way, and the frame or support may be fixed permanently at such
angles as may be found best for projecting light into the apartment, or be provided
with means of altering the angles at pleasure.
A reflector thus made receiving the light upon a large portion of the circumference
of each silvered glass tube will be able to project more light than the ordinary wavy
construction of surface with greater brilliancy, which may be further increased by
making the foundation of enamelled iron, it may easily be kept clean and its parts
readily replaced in cases of breakage.
When it is desired to reflect from both sides of reflector, the silvered glass tubes
will not be fixed upon a foundation but supported by wires or otherwise within the
frame.
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 :-
1. In a reflector the combination within a suitable frame of any size and shape
and upon a suitable foundation of series of glass tubes silvered inside, substantially
as described.
2. A reflector having glass tubes silvered inside as medium of reflection, constructed
combined and arranged to operate substantially as herein before described with
reference to the accompanying drawings.
