ALICE PROTHEROE, 101, Fentham Road, Birchfield, Birmingham, Schoolmistress,
do hereby declare the nature of this invention to be as follows:
This invention relates to a new and improved method of teaching form and
colour and colour combinations, or the alphabet and colour & colour combinations
in schools.
Various common geometrical shapes as the square, oblong, rhomboid, equilateral
triangle, right angled triangle, scalene triangle, pentagon, hexagon, octagon,
circle, oval, quadrant, &c., &c. are cut, punched, or stamped out in a sheet of
strong cardboard.
At the back along the top, bottom, and one side and also across the middle are
fixed strips of cardboard forming grooves which thus form two receptacles of equal
size into which may be slided sheets of coloured gelatine film. These sheets are
usually three in number blue, yellow, & red, to teach the primary colours.
When in use a sheet of yellow gelatine film is slided into one grooved receptacle
and a sheet of red gelatine film is slided into the other corresponding receptacle.
Half the geometrical forms assume the yellow colour of the first named film and
the other half of the geometrical forms assume the red colour of the second named
film. If now a sheet of blue gelatine film be slided into the first receptacle (the
yellow film remaining in) the geometrical forms at once assume the secondary
colour" green "which is formed by the combination of the primary colours
yellow and blue. In the same manner if the blue film is slided into the second
receptacle (the red film remaining in) the geometrical forms at once assume the
secondary colour, "purple." Combinations of the red and yellow films will
cause the geometrical forms to assume the secondary colour "orange."
Instead of cardboard may be used wood, tin, papier-mache, iron, brass, or other
metal, and in place of coloured gelatine films may be used coloured glass or other
transparent coloured substances.
In place of geometrical forms may be substituted the letters of the alphabet or
figures and the letters and figures will assume various colours in the same manner
as before described.
In this manner the teaching of form and colour and colour combinations or the
alphabet and colour & colour combinations is pleasantly combined and made
more vivid and impressive than by other means.

ALICE PROTHEROE, 101, Fentham Road, Birchfield, Birmingham, Schoolmistress,
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;-
This invention relates to a new and improved method of teaching form and
colour & colour combinations.
Various common geometrical shapes as the square, oblong, rhomboid, equilateral
triangle, right angled triangle, scalene triangle, pentagon, hexagon, octagon,
circle, oval, quadrant &c., &c., are cut, punched, or stamped out in a sheet of
strong cardboard (Fig. 1).
At the back along the top, bottom, and one side & also across the middle are
fixed strips of cardboard Fig. II^ forming grooves Fig. I which thus form two
receptacles of equal size Fig. II" into which may be slided sheets of coloured gela-
tine film Fig. II. These sheets are usually three in number, blue yellow &
red to teach the primary colours.
When in use a sheet of yellow gelatine film is slided into one grooved receptacle
and a sheet of red gelatine film is slided into the other corresponding receptacle.
Half the geometrical forms assume the yellow colour of the first named film and
the other half of the geometrical forms assume the red colour of the second named
film. If now a sheet of blue gelatine film be slided into the first receptacle, the
yellow film remaining in, the geometrical forms at once take the secondary
colour green which is formed by the combination of the primary colours
yellow and blue. In the same manner if the blue film is slided into the other
receptacle, the red remaining in, the geometrical forms at once assume the
secondary colour purple. Combinations of the primary colours red & yellow
films will cause the geometrical forms to assume the secondary colour orange.
Second Method. Instead of two grooved receptacles the grooves may be formed
along the top, bottom, & one side leaving one side open; or the grooves may be
formed along the bottom and two sides leaving the top open into which larger
receptacles thus formed may be slided larger sheets of coloured gelatine film in
the same manner as before. The whole of the geometrical shapes will then
assume various colours with each variation of coloured gelatine films.
Instead of cardboard may be used wood, tin, papier-mache, iron, brass or other
metal, and in place of coloured gelatine films may be used coloured glass or other
transparent substance.
Instead of geometrical shapes the letters of the alphabet or numbers may be
used & the letters or figures will assume various colours in the same manner as
before mentioned.
In this manner the teaching of form & colour, colour combinations, or the
alphabet & colour is pleasantly combined and made more vivid and impressive
than by means of printed colour diagrams.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
Improvements in educational appliances for teaching form & colour, colour
combinations, & the alphabet and colour, by means of gelatine films & stamped
or punched out geometrical figures or shapes, the alphabet, or numbers.
