or characters or are made transparent, and the
surface portion thereof made opaque around out
lines which de?ne letters or characters. Another
object is to provide a sign in which the character
20 displaying plates are carried by a belt contained
in a case and propelled by suitable means to pass
by a sight opening in the front of the case,
whereby a relatively long legend may be pre
sented to persons looking at the sign. Another
‘25 object is to provide character displaying plates
which may pass around rollers or other belt car
rying means. Another object is to provide means
. whereby the gaps between adjacent character
displaying plates are covered so as to prevent
30 any light from passing through the gaps between
adjacent edges of the plates.
Other objects and advantages will appear in
the course of this speci?cation and, with all of
said objects and advantages in view, this inven
35 tion consists in the several novel features of con
struction, arrangement and combination of parts
hereinafter fully set forth and claimed.
The invention is clearly illustrated in the draw
ings accompanying this speci?cation in which:
Referring to said drawings and ?rst of Figs. 1
to 5 inclusive, which illustrate the invention ap
plied to a sign in which the character displaying
plates travel, the reference character [5 desig
nates a rectangular case of any suitable construc- 20;
tion, formed with a sight opening I‘? in its front
wall l8. Rotatively mounted in said case ad
jacent each end thereof are rollers i9, 23 and I9“,
28*‘, the rollers l9 being arranged in pairs as
shown, and the rollers 20 being disposed in- 25
termediate those of the pairs. The rollers I941,
2|]a are disposed diagonally opposite each other
at two corners of the case. Trained around said
rollers is an endless belt 2! which carries the
character displaying plates 22 andapropels said 30 '
plates along the sight opening in the front wall
of the case where they are exposed to View. One
of the rollers, as for example the one designated
by I9“, is a driving roller and is rotated by a
motor 23 which may be in the form of a spring 35
motor, an electric motor or other power device.
In Fig. 2 the belt 21 is shown diagrammatically.
Fig. 1 is a front elevation of a sign embodying
one form of the present invention.
Fig. 2 is a horizontal section therethrough.
One or more electric light bulbs 24, or any other
source of illumination, is placed behind that
part of the belt which passes by the sight open- 40
ing, and re?ectors 25 may be employed in con
nection with the electric light bulbs to direct the

letters or characters formed in or by the plates 45
22 may be made perfectly legible and distinct in
the dark as well as the light.
The belt 2| is desirably composed of two closely
spaced ?exible upper bands 26 and a ?exible
lower U shaped band 2'! (see Figs. 3 and 4) 50
connected by upright plate spacing members
The bands and spacing members may be
composed of leather or other suitable belting so
as to enable the belt to pass around the rollers,
and the character displaying plates are ?exible 55
so that they may pass around the rollers. The secured at their ends to the strips 261*, 218*. Be
upright plate spacing members 28 are desirably tween above and below the sets of strips are
H shaped in cross-section as seen in Fig. 5, and strips or sheets 36 extending the entire length
each may be composed of two short strips secured of the frame and serving to exclude light from
the spaces between the several rows of letters.
The sheets 36 may be soldered to or may form
together along their. median lines by a row of
stitches 29, which stitches may also be used to
fasten the plate spacing members 28 to the
bands 26, 21. The bands and plate spacing mem
part of the rear strips 2'1BL and the forwardly
disposed strips 2‘!a have their lower edges se
cured to the rear strips 2'!a or to the sheets 36
bers provide rectangular spaces 30 in which are
so as to provide grooves for the reception of the 10
received the character displaying plates 22, which
may be slid down through the slots between the
bands 26 and down through the grooves in the
plate spacing members 28, bringing the lower:
edge portions of the plates into the groove formed
in the U shaped lower band 21.
The character display plates may be construct
ed in various ways. For instance, the bodies 3|
thereof may be made of thin flexible sheet metal,
cardboard or the like as shown in Fig. 3 and the
body of each plate may be cut out to de?ne a
letter or other character as at 32.
To the rear
face of the body 3| is adhesively secured a thin,
transparent sheet 33X, such as Cellophane, and
it may have any desirable color. An assortment
of character display plates containing the various
letters of the alphabet, digits, etc. may accom~
pany each sign so that the user thereof may read
ily' set up any display matter which is par
ticularly desirable for advertising his goods.
Between the words displayed, opaque plates 33
are placed in the belt so as to prevent light from
passing through the spaces between the plates
that display the words. The plate spacing mem
bers 28 and opaque plates 33 exclude all light ex
cept that which passes through the transparent
letters or characters, thereby preventing any un_
pleasant streaks of light to escape through the
sight opening at the front of the case.
In Figs. 6 and '7 a fragment of a link belt 2NL
4:0 is shown, and in this form of invention the links
are provided with upwardly extended socket
members Zlb adapted to receive tongues 22'’
formed upon the lower edges of the character
displaying plates 22*‘. These plates, like the
45 plates 22, have opaque surfaces formed with
transparent portions 32a which de?ne the out
lines of the letters of the alphabet or other char
acters, and the body portion of each plate is
formed with a ?ap 34 along one edge that extends
50 over the adjacent edge of the adjacent plate to
cover the gap therebetween so as to prevent any
light from passing through the gap between the
plates. In this form of plate the body may be
formed of glass or other transparent material 3|b
55 and the outline of the character may be formed
by painting the surface of the body around the
outline of the letter or character as at 33c so
as to leave that part transparent.
In the form of the invention illustrated in Figs.
60 8 to 14 inclusive, the invention is shown as ap
plied to a stationary sign. In this form a rec
tangular frame l6‘3L is provided and in said frame
is supported a stationary plate holding mem
ber 35. Said member is desirably composed of
65 several sets of upper and lower spaced strips 25a,
218*, each set being connected by upright plate
spacing H bars 282L soldered or otherwise rigidly
lower ends of the character displaying plates
as in the other form hereinbefore described.
. .The sign is made up by placing the letters,
which form words, in the spaces between the
“plate spacing bars '28a and as in the other form
described, and opaque plates 33 are placed in
the unoccupied spaces so as to prevent the light
from passing through said spaces. In this form
of the invention the character displaying plates
220 may be formed of opaque material having 20
cut-out portions to de?ne transparent letmrs and
transparent colored or clear thin sheets 33“, such
as Cellophane or. the like, are adhesively secured
to the rear sides of the bodies of the plates (see
Figs. 13 and 14).
This form of invention-may be supported in
show windows or wherever desired, and the light
issuing from illuminating ?xtures within the
store may be used to illuminate the sign from
behind, or, if desired, electric light bulbs and 30
reflectors may be placed behind the sign, as in
the form of the invention ?rst above described.
With either form of sign, the display may be
changed as often as is found desirable.
Thus in
eifect a different sign may be presented daily or
as often as required.
From the above it is apparent that a very inter
esting sign is provided which attracts the atten
tion of passersby. It may be made especially at
tractive by employing colored, transparent back
ing behind the cut-out portions of the char
acter display plates.

betweenrsaid members, said plates having opaque
surface portions outlining transparent portions

disposed in the spaces formed by the bands and
plate spacing members, said plates having opaque
surface portions outlining transparent portions
