A Novel Educational Device relating to the Blending of Colors.
I, GEORGE REGINALD GILL, Wavertree, Loats Road, Clapham, London, S.W.
Educational Publisher, 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:-
My invention is devised primarily with the object of teaching by means of the
hereunder described simple and easily manipulated means
or apparatus, the
resultant effects produced by the blending or assimilating together of dissimilar
colors.
And in order that my invention may the better be understood, I have appended
the accompanying sheet of illustrations referring thereto-
Figure 1 being a front vertical elevational view of the device complete and
Figure 2 a plan taken on top of Figure 1, Figure 3 is a corresponding view to
Figure 1 but with the hereunder referred to circular rotatable frame B removed;
Figure 4 being plan taken on top of Figure 3.
In carrying out my invention I employ a stationary frame A provided with a
series of openings a filled in with any transparent substance say glass, gelatine,
mica &c., each of the glazed panels a being a different color.
An aperture is formed at the centre of B through which is passed a pin, stud or
the like 6 and secured by a nut at the back A distance piece c being introduced as
shewn, so as to allow of a clearance between the frame A and the rotatable circular
frame B which is mounted on the pin b. The rotatable frame B is also formed
with openings a¹ which when the complete device is in its normal position will
correspond with the glazed panels a of A. The openings a¹ are also glazed
similarly as in the case of those, a of the frame A, each of the panels being of
corresponding color thereto. Now assuming the normal position of B to be that
when the colors of the glazed panels of the two frames correspond; for instance
the blue panel of B corresponding with that of A, then, the teacher in proceeding
to demonstrate the results of the blending together of the different colors, say the
resultant color when the blue is blended with yellow, then it is only necessary to
turn round the rotatable frame B until the blue panel therein coincides with the
yellow panel of A. Again, say, giving the case of illustrating the production of
purple, the demonstrator would turn the rotatable frame B until the blue glazed
panel therein coincides with the red glazed panel of A and so on.
The 2 frames are provided with indices of primary colors for the guidance of the
teacher and pupils seeing at a glance the combinations or alterations of tints arising
from the blending of two different colors together on turning the rotatable frame B
all as hereinbefore set forth.
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,
First. The means substantially as herein set forth for teaching the effects pro-
duced by the blending together of dissimilar colors.
Second. The improvements substantially as herein described and for the purposes
set forth.
