Year: 1880

page_text: LETTERS PATENT to William Arthur Smith Benson, of Kensington, Architect,
for an Invention of "IMPROVEMENTS IN APPARATUS FOR THE DISTRIBUTION
OF ARTIFICIAL LIGHT."
PROVISIONAL SPECIFICATION left by the said William Arthur Smith
Benson at the Office of the Commissioners of Patents on the 19th October
1880.
WILLIAM ARTHUR SMITH BENSON, of Kensington, Architect.
IN APPARATUS FOR THE DISTRIBUTION OF ARTIFICIAL LIGHT."

"IMPROVEMENTS
The improvements consist in placing an opaque shield or shields before or under
artificial light, and a reflector or reflectors at the back or over the light,
according to the direction in which the light is to be reflected, the object being to
screen from sight the flame of the light itself, and consequently the glare, and to
light up rooms, matters, and things by a diffused and equal light. The light may
be produced by any of the existing means, and any convenient burner or holder
may be used; the shield is made opaque, and preferably concave, and with a
polished surface, whereby the light is reflected by said shield against the reflector
proper, and so the rays of light are projected into the room or in other desired
direction; the shields and reflectors are best made of metal, and the reflector proper
should not be smooth, but slightly corrugated or uneven on the surface for the
purpose of more thoroughly spreading the rays.

"IMPROVEMENTS
The improvements consist in placing an opaque shield or shields before or under
artificial light, and a reflector or reflectors at the back or over the light, according
to the direction in which the light is to be reflected, the object being to screen from
sight the flame of the light itself, and consequently the glare, and to light up rooms,
matters, and things by a diffused and equal light. The light may be produced by
any of the existing means, and any convenient burner or holder may be used; tho
shield is made opaque, and preferably concave, and with a polished surface, whereby
the light is reflected by said shield against the reflector proper, and so the rays of light
are projected into the room or in other desired direction; the shields and reflectors
are best made of metal, and the reflector proper should not be smooth, but slightly
corrugated or uneven on the surface for the purpose of more thoroughly sprending
the rays.
The accompanying Drawing, where like letters represents corresponding parts, is
intended to illustrate a convenient mode of performing my Invention, but as to
matters of detail it is obvious that the same may be varied to suit particular cases.
Fig. 1 is a plan view of a wall arrangement. e is the wall; c, a reflector or
diffuser; a, jet or flame; b, opaque shield or screen having its surface towards the
light made highly reflective. Fig. 2 shows a variation of the same arrangement;
Fig. 3 shows a simple adaptation to a pendant or pillar lamp. c, the reflector ;
b, the shield or screen made in a cup like form; a, the light.
I do not limit myself to the actual forms or arrangements shown, as these may
be considerably varied without departing from the nature of my Invention. The
shield or screen may also conveniently be made up of two or more cup or disc
shape opaque substances.
In witness whereof, I, the said William Arthur Smith Benson, have hereunto
set my hand and scal, this Eleventh day of April, A.D. 1881.
