various terms used‘in the specification and claims.
B-y-“indicia” I mean markings at the surface
The indicia may be animating or
non-animating and maybe pictorial or non-pic
torial.
The ‘indicia may, combine to de?ne an 55

object, or may be entirely separate from each
other, or may be superposedat least in part.
By “background” I mean the portions ofthe
sign contacting the Whole or a major portion of
the periphery of the indicia andextending out
Wardly therefrom an indedeterminate distance.
Thus the background may be merely an outline
or border around the indicia, or may be the
whole or a large portion of the ?eld upon which
10 the indicia are displayed. For‘ instance, the in
dicia may assume the form of ?gures or letters
and may have a contrastingly colored border of
neutral or non-neutral color and in such case
the borders can be regarded as the background.
15
By “illumination” I mean the casting of col
ored lights upon the sign in accordance with this
invention.
,
.
v
'
'
By “neutral color” I mean a color that has no
distinguishing or dominant hue. Examples of
20 such are white, black, grey or brown.
‘
.By “dominant hue” or “distinguishing hue” I
mean a color which has a predominant wave band
which makes the light appear to an observer to
be of particular color. For example, a light
25 whichan observer might call “red” may contain
some yellow or blue light which is not apparent
due to the overwhelming preponderancy of wave
bandsin the red portion of the visible spectrum.
Thus, whenever I state that a light has a “dom
3.0 inant hue” or is of a certain “color” I means to
include not only substantially monochromatic
light but also impure colors which generally have
the same appearance as the monochromatic light.
A speci?c example of this is that when I say “red”
3.5, I mean'to include among others, impure colors
generally known as magenta and scarlet but
which have predominant red wave bands.
By. “cyclic color change” I mean the exposure
of the sign to light of one color for its full time
40 interval and to the other color through its full
time interval and until the beginning of the next
exposure of the sign to light of the ?rst color.
By “non-animating” I mean that the part or
parts referred to are colored in colors, including
45 neutral colors, which are not animated when sub
jected to light which animates'other portions of
the
sign.
.
.
.
.
'
In ampli?cation of the nature of non-animat
ing colors, the properties of a color which render
50
it non-animating are:
-
,
'
(a) * Its ability to re?ect back both of the col
ors alternately cast upon the sign. Such colors
may be white, grey, brown, yellow, etc.
(b) Its ability to absorb both colors cast upon
55 the sign. Such colors maybe black, dark blue,
etc.
-
By “basic or “primary animation” I mean the
illusion of animation produced physiologically
by the alternate lighting arrangement of my in
60 vention. This is'to be distinguished from the
illusion of natural-movement or directional mo
tion which is psychologically produced. This
psychological illusion ampli?es and gives direc~
tion to the physiologically created basic anima
65
tion.
'
By “discrete” I mean‘ separate and individual
images are observed as distinguished from im
ages which, due to the persistency of vision, op
tically blend and appear continuously visible.
With reference to Figure 1 a sign I! having a
as a non-neutral color, or a color complementary
to that of part I 3.
Animating part l3 which may be composed of
one or several different co-operating or non-coop
erating representations, iscolored in a color which
has a distinguishing or dominant hue. Since
colors having high energy value are preferred in
signs, the animating color is preferably red al
though any color may be selected as desired.
Non-animating part M, which may or may not 10
be composed of one or several different co—oper
ating or non-co-operating representations, is col
ored in a color which may have a dominant hue
or may be neutral, but which is selected to be
[constantly visible no matter what color is being 15
projected on the sign.
The sign is preferably illuminated by a pro
jector which casts differently colored lights al
ternately upon the same.
'
Such a projector may comprise a pair of lamps 20
before each of which is disposed alight ?lter of
suitable color with the lamp circuits controlled
by suitable ?asher switches, or may comprise the
rotatable color ?lter assembly of Figure 8, later
to be described.
25
One of these color screens or ?lters is designed
to pass light which has the same dominant due as
the animating color on the sign. The other color
screen or ?lter is designed to pass light which
is de?cient in the dominant hue of the animating 30
indicia. In practice it has been found Very satis
factory to project complementary colored lights
upon the sign. For example, where red primary
indicia markings are used, red and green lights
are projected on the sign.
The secondary or non
Suitable and preferable animating indicia colors
are red, green and blue. Suitable and preferable
non-animating colors are yellow, orange, green, 40
blue or violet or even a neutral color.
The non-animating indicia may be located upon
the same colored background as the animating
indicia or may have provided for it a background
of a different color.
45
In operation the ?asher in the circuit of the
vlamps in projector it is operated to alternately
andsuccessively light these lamps thereby cast
ing alternate ?ashes of differently colored light
upon the sign ll. When light of the animating
color falls on the sign the primary animating
portion I3 and the non-animating portion M are
both visible to an observer but, when the non
animating light is being projected, portion I3 is
not visible in its own color because the non
animating light-is de?cient in the dominant hue
of portion l3 vand will therefore not be re?ected
or transmitted thereby.
'
Hence the observer views a sign background
upon which the primary indicia are alternately 60
visible and the secondary indicia are constantly
visible. When the cyclic color frequency has been
regulated properly the primary part I3 Will be
seen alternately as discrete images and will pre
sent an appearance of animation comprising a 65
pulsating movement due mostly to the effect of
chromatic aberration in the eye and a bodily
movement in space relative to the background.
In some cases there is a stereoscopic effect so
that the indicia appears to stand out from the 70

colored portions of the sign,
that the invention'is equally
signs having.‘ translucent or
portions for producing ‘the
same effects. Where such light permeable signs
are used, the" source of-light such as the pro
jector of Figure 8 is located. behind the sign and
the modi?ed light is transmitted to the eye of
the observer. Furthermore translucent'signs may
10 be used to produce the same lighting effects.
For carrying out my invention where an illu
sion of natural or directional movement is de
sired, the object to be given the appearance of
motion should be studied and analyzed.
The
15 best arrangement of animating'and non-animat
ing lines should be selected‘ifo'r the sign. For
example, it-may be best‘to locate the animation
producing lines entirely separate from the ob
ject to be animated and which ‘appears to move
as in Figure 7.
_
Selection 'of the frequency of cyclic color
change depends upon the character of the object
portrayed. For example, the frequency when
showing a gull ‘in ?ight would be lower than that
25 employed to show liquid flow from a bottle or a
speeding auto-mobile. In most cases, while the
primary or basic animation may be small the
secondary or psychological effect is usually am
pli?ed and quite natural.
30
The invention may be embodied in other spe
ci?c forms ‘without departing from the spirit or
essential characteristics thereof. The present
embodiment is therefore to be considered in all
respects as illustrative and not restrictive, the
35 scope of the invention being indicated by the
appended claims rather than by the foregoing
description, and all changes which~come within
the meaning and range of equivalency-of the
claims are therefore intended to‘ be'embraced
40
therein.
