This invention relates to display signs, and
more particularly to signs in which advertising
Hmatter is presented to view in changing or dis
solving effect, that is, moving before the vision
-of a» person observing the same,'successively in
an obverse direction to the direction of reading
"or alternating view ineither direction, thus pro
vidingan attractive and inexpensive medium of
bringing advertising or` slogans for products or
wares before the purchasing public. .
sThe inventionfurther contemplates an illumi
(Cl. 40-40)
for movably or rotatably supporting a heat lamp
I8. This heat lamp may be of any preferred de
sign but is shown as embodying a transparent
chamber or cylinder I9 of celluloìd or other trans
parency reinforced by bands 20 at the upper and
lower ends thereof and held by staples or other
fasteners 2 I, certain of which pass through over
lapping portions 22 of the transparent cylinder
and the bands.
The cylinder I9 is arranged within a casing in
-na-ted display' or -sign device in the form of a
the form of a shade 23 of opaque material such
as cardboard suitably ornamented externally to
heat lamp embodying an opaque casing adapted
render the same attractive in appearance. As il
,':tobemoved or rotated about ai lamp bulb and
12155 ¿having one or ’more sides ywith an opening there
`in` and la corrugated or similar panel set behind
lustrated, this casing is triangular in cross-sec
tion, but may be any suitable shape, and instead
of being polysided, may simply be a wall suitably
the ¿opening with a plurality of display characters
Ithereon visible at difîerent angles, thus providing
arranged in front of a lamp or other illuminating
means and arranged to completely or partially
an lattractive device with a constant change of
y.characters or reading matter.
Another object of the invention is to provide
"a .novel display panel and arrangement ofdis
¿play matter thereon in conjunction with the mov
ing casing or Wall and an opening through which
.theV panelis displayed in front of an illuminating
means, if desired.
-¿ Other objects and advantages will appear and
revolve or rotate about the same or have other
form of movement imparted thereto such as oscil 20
latory movement or otherwise. The shade 23
may be formed of a strip and the ends thereof
may be overlapped and glued or otherwise fas
tened as at 23a at one corner or otherwise.
The shade or casing 23 is open at the bottom 25
so as to y:tit over the lamp bulb and is closed near
the top by a. wall 24 shown having edge portions
25 folded upwardly against the inner faces of

Referring more particularly to the drawings,

’.trolled `by a switch I4. A bulb I5 fits in the

having a pointed bearing I‘I extending upwardly
20 so as to suspend the cylinder.
Over the opening 26 in the wall 24 is arranged
a fan 28, certain blades of which have tongues
29 extended through slots in the top 24 and
clinched, as particularly seen in Fig. 5. The fan
28 is preferably of metal and has a central open
ing 30 receiving a bubous glass or other bearing
3| with a spherical closed upper end and a flange
32 at the bottom disposed against the bottom
face of the central portion of the fan and held in
position by a clip 33 above said central portion.
This bearing is designed to ñt over the pin bear
ing I'I so that the heat from the bulb and the
heat waves impinging upon the blades 28 will
cause the shade to rotate in a given direction 50
according to the angular position of the blades.
Each side of the shade or casing 23 is provided
With an opening 34 which, while shown oval, may
be of other desired geometrical outline. Ar
ranged in back of each opening is a panel 35 of 55
2 ,
paper or other suitable translucent material
shown corrugated and suitably glued or other
wise fastened to the inner faces of the sides of
the shade at the ends 36 as well as at the top and
bottom edges so as to entirely cover the open
ing Sli-and overlie the edges thereof. The alter
nate-or opposed faces of the corrugations are
printed or otherwise produced with suitable sets
of characters 3l and 38, parts of each character
10 being printedor- otherwise producedupon alter
nate or staggered walls of the corrugations fac
ing in the same direction so that when viewed at
different angles from vone direction, one of the
characters will be visible and when viewed at di'f
15 ferent angles from the opposite direction, lthe
rotate, and especially adverse to the direction of
reading, it is to be understood that the panel
may be moved in any other way or may have
limited rotation or may be oscillated to render
the different characters successively visible. This
provides an attractive display of advertising mat
ter whereby said advertising matter or slogans
pertaining to products may be brought before the
purchasing public and, therefore, constitutes an
inexpensive medium of advertising.
Itis also to be understood, instead of sharp
angular portions of the corrugations, as illus
~ trated, the panel may be otherwise suitably corru
gated in sinuous or wavy form with similar eñ‘ect
upon the display matter or characters thereon, 15
but in either case, the opposite sides or outer
may be suitabh7 ornamented or colored andthe exposed folds or sides of the corrugations bear

It may also be mentioned that while the im

angle, and then corrugated alongthe lines of the
divisions between these corrugations, as will be
more readily apparent from Fig.~8 of the draw

45 method of producing the panels economically in
quantities so that the advertising matter thereof

Having thusy described my invention, what I
claim as new and desire to secure by Letters Pat

In Fig.. 9 of the drawings, .a modification is
While I have illustrated and described the pre
ferred forrn of construction for carrying my in
vention into effect, this is capable of variation and
modification without departing from the spirit of
the invention. I, therefore, do not wish to be
limited to the precise details of construction set
forth, but desire to avail myself of such varia

55 of panels together with the Acharacters thereon
may be producedat one time and then fastened
in position overthe openings, after corrugating.
In either instance,>it will'be obvious that the pri

bearing characters of contrasting design thereon
`in which divisional portions of -the characters are
produced upon spaced alternate' or staggered divi
65 sions of the panel. Thus, when the panel is cor
rugated, the portions of the different characters
facing ’in the ysame -angular 'direction will be
to ymove so as to present the characters from
different angles of view.
