This invention relates to indicator devices.
An object of the invention is to provide an
the conveyor to the other side. The overlying
faces of adjacent panels bear identical markings
indicator device which is particularly adapted
so that when a panel is turned over it bears on
for use as a score board so as to be easily operated to indicate the score in such a manner that
the identical score indication is simultaneously
its exposed face the same indicia as that on
the uncovered face'of the next succeeding panel. I
Thus the same indication or score is simultane- 5
visible on the opposite sides of the indicator
device. The same principle may be employed
in connection with clocks or the like wherein
10 it is desirable to expose to view identical indi-
ously exhibited on both sides of the conveyor and
in opposite directions to each other. In a score
board the pairs of identical numerals are in con
secutive series on the superimposed faces of a 10
cations in opposite directions simultaneously.
My invention pertains to improvements related
to the type of indicator devices disclosed in my
Patent No. 2,057,719, issued on October 20, 1936,
15 for Indicator board, and also in my copending
series of pairs of panels. Each panel therefore
is paired with a preceding panel as to one nu
moral, and is paired with the next succeeding
panel as to the next consecutive numeral of a
series. The whole series of overlapping panels :15

are moved intermittently by manipulation of the
?led May 13, 1936.
Another object of this invention is to provide
an indicator device which is highly useful and
PO simple in construction. Convenience of arrange-
conveyor so as to turn the panels over one by
one.
In carrying out my invention in the illustra
tive embodiment herein I make use of a frame
“
which has a base I l ‘and three upright posts l2. 2,0
Each post I2 has a longitudinal cavity [3 at its
top portion. In each space on each side of the
center post is a score board device for indicating
ment, lightness and comparative inexpense of
manufacture are further objects which have been
borne in mind in the production and development of the invention.
05
It will be understood that various changes in
M
the details of construction may be made without departing from the spirit or scope of the
invention as de?ned by the appended claims.
With the foregoing and other objects in view,
30 which will be made manifest in the following
detailed description and speci?cally pointed out
in the appended claims, reference is had to the
accompanying drawings for the illustrative embodiment of the invention, wherein:
35

of my device.
Figure 3 is a detail view of the reverse face
of the next following panel of my device.

Figure 4 is a fragmental sectional view of my
device.
Figure 5 is a face view of a modi?ed form of
my indicator device, with the cover partly broken

Figure 6 is a fragmental view of the panels
and conveyor of my modi?ed indicator device.
Figure '7 is a detail view of a panel of my
modi?ed device, showing one face of the panel;
and
50
Figure 8 is a detail view of the same showing
the other face of the panel.
In its general organization the preferred form
of my invention consists of a plurality of panels
in overlapping position on a conveyor so as to
55 turn over the panels one by one from one side of
the score of the opposing teams in a game.
.
The two score board devices are identical, 25
therefore description of one will suf?ce. An
idler roller M has its reduced ends 16 extended
through elongated slots near the top of the re
spective posts l2. Each slot is located on the
inner side of the post I2 and communicates with 30
the cavity l3. A journal block I8 is slidably dis
posed in each cavity l3 and rests on a tension
spring l9 whereby it is urged upwardly toward
the top of the post 12. Each reduced end [6 of
each roller I4 is journaled in one of said journal
blocks 18. Spaced below the idler roller and
parallel therewith is another roller 2| journalled
between the posts 12. A reduced end 22 of this
roller 2! is extended through the outer post I2
and is provided with a knob 23 whereby the roll
er 2| may be turned. Over these rollers is ex
tended a belt conveyor 24 of such length that
it is held suitably taut by the upward force ex
erted by the springs I!) on the upper roller l4.
It is to be noted that the upper roller I 4 is
of much smaller diameter than the lower roller
2! so as to provide a suitable downward and
outward incline on both sides of the device. On
the conveyor 24 are secured a plurality of indi-

Such consecutive panels are shown in Figures 2

bears the numeral “11”, and the other face bears
the following consecutive numeral “12,”. The
of said series bearing the same score indicia so :25
panels 26a and 261) are so placed on the conveyor
'24 that the panel 26a precedes the panel 25b for
instance in contraclockwise direction viewing Fig.
30 1 and so that the faces of the panels 25a and
261) which bear the same indicia namely the
numeral “11” are superimposed facing each other
in all positions except when separated by the top
roller l4. Hence each pair of adjacent panels
on its combined four faces bears three consecu
tive numerals, one numeral, for instance “10”, on
the leading face of the ?rst panel 26a, the next
consecutive numeral, in this illustration “11", on
both the trailing face of the ?rst panel 26a and‘
also on the adjacent leading face of the next panel
26b, and the next consecutive numeral, namely
“12” in this illustration, on the trailing face of
the second panel 26b.
.
In operation each set of panels is used for one
of the teams.
The scoreboard is so set up near
an official that its opposite sides face toward the
opposite stands or benches of the spectators. The
o?icial turns the device by means of the knob
23 as the respective teams score so as to bring
into view the suitable numerals at the top of the
conveyor.
In the modi?ed embodiment of my device each
panel 3| bears the same numeral or indicia on
both sides. The panels 3| do not hang ?at with
55 their face toward the conveyor as in the first de
scribed embodiment but extend substantially at
right angles away from the conveyor chains 32.
Each panel 3! is connected to‘ the conveyor chain
32 by means of a yoke 33 fixed to spaced links
60 of the conveyor 32. Each panel 3! is placed into
a yoke 33 and is held therein by a pin 34:. The
yoke 33 is comparatively small and is located near
a leading corner of each panel 3! so that the in
ner or bottom edge of each panel 3| rests against
65 the bottom of a yoke 33 as it is carried around
with the conveyor 32.
