IMPROVEMENTS IN DWARF WINDOW BLINDS; APPLICABLE ALSO TO OTHER PURPOSES
Year: 1884

page_text: I WILLIAM KAY of N° 5 Chancery Lane in the County of Middlesex do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN DWARF WINDOW
BLINDS; APPLICABLE ALSO TO OTHER PURPOSES" to be as follows:
My Invention has for its object improvements in dwarf window blinds, applicable
also to other purposes.
I take a solution of Fluorescene or Aniline or other coloring matter in a
gelatinous or liquid medium, treated antiseptically with boro-glyceride or other
suitable chemical substance and place the said solution in a cell of glass or other
transparent matter or float it upon the surface of glass as collodion is floated
upon the photographic plates-or form films of the gelatinous solution that may be
placed upon glass or between two glasses.
Such cell or glass to which the film is applied may be used for dwarf window
blinds as painted glass is now used and is applicable to other purposes, such as,
windows in hall doors, side windows in halls, the back lights of shop fronts,
windows in partitions for rooms with borrowed lights, or consulting or operating
rooms.
The solution may be suitably made in the following manner and proportions:-
Dissolve one pound of gelatine in one pound of water, to which add two pounds
of glycerine already mixed with sufficient caustic ammonia or soda solution to
dissolve three hundred grains of Fluorescene.
Add to the mixture whilst still hot and thoroughly inter-mix one ounce of boro-
glyceride.
These proportions may be varied within very wide limits according to the tint
and consistency desired.

I, WILLIAM KAY of 5 Chancery Lane in the county of Middlesex do hereby
declare the nature of the said Invention for IMPROVEMENTS IN DWARF WINDOW-
BLINDS APPLICABLE ALSO TO OTHER PURPOSES" and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :—
My Invention has for its object Improvements in dwarf window-blinds applicable
also to other purposes.
I take a solution of fluorescene or aniline or other colouring matter in a
gelatinous or liquid medium, treated antiseptically with boro-glyceride or other
suitable chemical substance and place the said solution in a cell of glass or other
transparent matter, or float it upon the surface of glass as collodion is floated upon
photographic plates; or form films of the gelatinous solution that may be placed
upon glass or between two glasses.
Such cell or glass to which the film is applied may be used for dwarf window-
blinds as painted glass is now used and is applicable to other purposes, such as
windows in hall-doors, side windows in halls, the back lights of shop fronts windows
in partitions for rooms with borrowed lights. or consulting or operating rooms.
The solution may be suitably made in the following manner and proportions.
Dissolve one pound of gelatine in one pound of water to which add two pounds
of glycerine already mixed with sufficient caustic ammonia or soda solution to
dissolve three hundred grains of fluorescence.
Add to the mixture whilst still hot and thoroughly intermix one ounce of
boro-glyceride.
These proportions may be varied within very wide limits according to the tint
and consistency desired.
Having thus described the nature of my Invention and the manner in which the
same is to be performed I would have it understood that I claim
The employment of a gelatinous compound similar to the one berein described
for window-blinds, screens, and other like purposes.
