PROVISIONAL SPECIFICATION.
Improvements in or relating to Lamp Globes, Bulbs, or Glasses.
I, CARL MORITZ WOHLMUTH of IV, Rubensgasse 9, Vienna, Empire of
Austria do hereby declare the nature of this invention to be as follows:-
The spherical or otherwise shaped globes, bulbs and glasses, used hitherto for
electric arc-light and incandescent gas-light, as well as for other modes of lighting,
when employed for shop windows or for lighting some object on the outside, have
the drawback, that the goods or objects to be lighted receive only a com-
paratively small part of the light as it passes through the glass uniformly in every
direction.
The object of the present invention is the production of glasses for light-
emitting bodies, which allow the full light to pass only on the side turned to the
object, while the part of the glass turned away from the object is only translucent
and therefore emits only a small amount of light.
The transparent part of the globe is turned to the object to be lighted, while the
opaque or non-transparent part of it, which reflects a part of the rays emitted by
the source of light is turned away.
The shape of the globe and of the opaque and transparent parts of it may be
arranged suitably to the requirements of the light. The glass may be rendered
opaque or semi-transparent by some known means suitable for treating the
globes.
Dated this 6th day of February 1896.

Improvements in or relating to Lamp Globes, Bulbs, or Glasses.
I, CARL MORITZ WOHLMUTH, of IV, Rubensgasse 9, Vienna, Empire of
Austria, 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 spherical or otherwise shaped globes, bulbs and glasses, used hitherto for
electric arc-light and incandescent gas-light, as well as for other modes of lighting,
when employed for shop windows or for lighting some object on the outside, have
the drawback that the goods or objects to be lighted receive only a com-
paratively small part of the light, as it passes through the glass uniformly in every
direction.
The object of the present invention is the production of glasses for light-
emitting bodies, which allow the full light to pass only on the side turned to the
object to be illuminated while the part of the glass turned away from the object is
only translucent and therefore emits only a small amount of light.

page_text: The accompanying, drawing represents as an example such a glass or globe for
arc-light for shopwindow lighting..
Fig. 1, shows it in side elevation and
Fig. 2, shows a view from below.
a is the transparent part of the globe turned to the object to be lighted, while
6 is the opaque or non-transparent or semi-transparent part of it, which reflects a
part of the rays emitted by the source of light back to a.
The shape of the globe and of the opaque and transparent parts of it may be
arranged suitably to the requirements of the light. The glass may be rendered
opaque or semi-transparent by any known means suitable for treating the globes.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. Globes, bulbs and glasses for light-emitting bodies in which the part turned
to the object to be lighted is transparent, whereas the remaining part is not
transparent or only partly transparent substantially as described.
