PROVISIONAL SPECIFICATION.
Improvements in or connected with Reflectors and other Articles of
Silvered Glass.
We, OSKAR RAAKE and JOHANNES GOBEL, both of 8, Schomburgstrasse Cassel,
in the Empire of Germany, Manufacturers, do hereby declare the nature of this
invention to be as follows:-
: -
The invention relates to improvements in or connected with reflectors and other
articles of silvered glass such for example as globes for the electric arc or incan-
descent electric light, or incandescent gas light or tubes such as Crookes's or
Geissler's tubes or rods and either partly or wholly silvered.
Silvered surfaces of the above description are liable to become tarnished or
oxidized especially when exposed to the atmosphere and sometimes injured by
handling or otherwise coming into contact with other surfaces and the object of
the present invention is to protect the coating of silver against such deteriora-
tion.
In carrying the invention into effect the glass globe, tube, or other article
may be of any suitable shape and have a plain surface or be formed or provided
either internally or externally with a pattern or design either in relief or recessed.
This glass article is partially or entirely coated with silver in the manner well
known but instead of leaving such silvered surface exposed as heretofore it is accord-
ing to the present invention covered with a protective coating of transparent varnish
or cement of such a nature that it will not be liable to scale or break off but will
efficiently protect the silver against tarnishing and atmospheric influence and
generally render the same weather proof.
By the means hereinbefore described silvered glass surfaces are rendered more
durable than heretofore and the tarnishing thereof is retarded or prevented.

COMPLETE SPECIFICATION.
Improvements in or connected with Reflectors and other Articles of
Silvered Glass..
We, OSKAR RAAKE and JOHANNES GOBEL, both of 8, Schomburgstrasse Cassel,
in the Empire of Germany, Manufacturers, 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 invention relates to improvements in or connected with reflectors and other
articles of silvered glass such for example as globes for the electric arc or incan-

page_text: descent electric light, or incandescent gas light or tubes such as Crookes's or
Geissler's tubes or rods and either partly or wholly silvered.
Silvered surfaces of the above description are liable to become tarnished or
oxidized especially when exposed to the atmosphere and sometimes injured by
handling or otherwise coming into contact with other surfaces and the object of
the present invention is to protect the coating of silver against such deteriora-
tion.
In carrying the invention into effect the glass shade, globe, tube or other article
may be of any suitable shape and have a plain surface or be formed or provided
either internally or externally with a pattern or design either in relief or recessed.
This glass article is partially or entirely coated with silver in the manner well
known but instead of leaving such silvered surface exposed as heretofore it is
according to the present invention covered with a protective coating of any suitable
transparent varnish that will not scale or break off, but will efficiently protect the
silver against tarnishing and atmospheric influence and generally render the same
weatherproof.
By the means herein before described silvered glass surfaces are rendered more
durable than heretofore and the tarnishing thereof is retarded or prevented.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. A reflector or other article of silvered glass covered with a protective coating
of suitable weatherproof varnish substantially as herein described.
2. The herein described method of protecting silvered glass surfaces consisting
in covering them with a coating of suitable weatherproof varnish substantially as
herein described.
