Application August 12, 1937, Serial No. 158,717
12 Claims. (Cl. 40—130)
This invention relates to an improved advertis
ing device and particularly to an advertising
device in which certain elements or letters are
adapted to move.
It is intended primarily to
provide positive means for imparting movement
5
to signs or the element forming the complete or
part of the complete advertising device or devices
whereby attention is attracted thereto.
An object of the invention is to provide means
for causing letters or elements to move in a given
manner and having associated with the elements
imparting the motion, means for illuminating the
letters or elements.
A further object of the invention is to provide
an advertising medium in which at least certain
elements or letters are adapted to move in a pre
determined manner.
Another object of the invention is to provide a
sign of the type with characters on its advertising
surface or surfaces which are moveable relative
to the sign and operated so as to attract attention
to the advertising device.
Another object of the invention is to provide
advertising device, or sign, which can be manu
factured and maintained in operating condition
at a minimum cost.
With the foregoing and other objects in View
the invention consists of the novel construction,
arrangement and combination of parts herein
to hollow pipe. member ll, through the
of block l2 and pin l3. Block I2 is
secured to the element H], for example
Ill and nuts l5. An opening is provided 10
in block l2 into which one end of shaft l0 ex
tends. Secured to the letter, character, or ele
ment I0 is illuminating me'ans I6. The illuminat
ing means is preferably of the neon type. The
letter forms a housing ll of suf?cient depth to 15
shield or house the connection between the tube
ends extending through the letter near the ends
of such letter and the conductors l8. The con—,
ductors l8 extend through apertures in the shaft
ii. The apertures are properly bushed to give
protection to the conductors l8.
The conductors extend along the inside of the
shaft H and pass out through the shaft walls
near the rear end of the shaft.
Suitable insula
tion material l9 separates the conductors from 25
each other and from the Walls of the shaft. The
insulation i9 is so arranged that shifting thereof
is prohibited. The rear end of the shaft is closed
by block 20 which block is secured to shaft l I by
any suitable means such as pin 2|.

or element does not wobble and the arrangement
shown prevents this undesirable result. Mounted 40
on support 25 are bearing members 26 and 21
which are suitably secured to the support 25.
Secured around shaft I0 is member 28 which is
clamped to the shaft by a set screw 29. Formed
This invention is an improvement on an ad

In the accompanying drawing wherein is shown
one embodiment of the invention but it is to be
understood that changes, variations and modi?
cations may be resorted to which fall Within the
scope of the claims hereto appended.
The advertising device hereinafter to be de
scribed is adapted to be used on moving vehicles,

tages have been overcome in my invention by
securing lever 30 to the shaft at substantially the
center of gravity of the shaft and the letter.
Referring to the drawing in detail, l0 indicates
an advertising element which in the drawing is
the letter “I”. ‘The element I0 is operatively
The con
ductors are secured to block 20 by any desired
means such as bolts 22, and nut 23.
When a series of letters, characters or elements
are used the conductor 24 connects to the adja
cent letter, character or element. Current for
illuminating the lights I6 is furnished to con
ductors 25 for any suitable source of supply.
It is highly important that the letter, character

In advertising devices in which elements are
moved, there is a tendency for the moving ele
60 ments to vibrate and wobble.
These disadvan
or elements are used suitable means of connect
ing the levers together near their free ends is
used. Motion is imparted to upper lever 30 which
transmits the movement to letter, character or
elements l0.
If desired the moving letters, etc., may be
mounted in front of a suitable background.
It
is highly desirable that the unit shown in Figure 5,5
1 be completely enclosed in a suitable housing.
Modi?cations are possible without departing
from the spirit of my invention or exceeding the
‘scope of the claims.

adapted to be rocked through a limited arc,
luminescent tubes formed to conform to the
shape of the letter, said tubes’ ends passing
Shaft I I may be and preferably is of “Bakelite”

suitable material.‘
Shown in Figure 6 is one form the sign may
take. An enclosing member 35 is provided with
a suitable face in front of which is adapted'to
move letter If].
