sion of relatively cheap cardboard display units
This invention relates to improvements in dis
play structures, and more particularly to action which may be assembled around a power unit to
displays of the character utilized in store windows
and similar show places to attract the attention
5 of pedestrians passing by, although the invention
will have other uses and purposes as will be ap
parent to one skilled in the art.
In theart of advertising, it has become uni
versally recognized that a display advertisement
10 in a store Window or the like is considerably
more effective if motivated or constructed so that
one or more parts thereof is normally in motion.
A movement quickly attracts the eye of a passer
by and once atracted the person will usually
linger suñìciently to ascertain the reason for the
motion. If the display is of proper construc
tion that length of time is quite ample to convey
to the passer-by the nature of the article being
advertised. However, heretofore action displays
have been prohibitively expensive for general and
extensive usage.
This expense is ~involved in the
cost .and labor of design and construction of the
various parts of the display, the labor involved in
building up the display, the installation and re
25 moval, reinstallation and the general attention
form an action display, the different members of
the display varying in size and form at dilîerent
points sufficiently to prevent the installation of CTI
any member in any except the right position.
Another object of this invention is the provi
sion of suitable shaft construction for operating
movable parts of an action display, such shaft
constructionbeing supportable in operating posi
tion by simple, cheap members of cardboard or
similar material without any resultant binding
of the shaft regardless of the warping of the card
board members, and obviously there will be no
wear from operating parts upon the cardboard
The invention also contemplates the provision
of various members of cardboard and the like for
assembling into an action display, the construc
tion being such that the members are readily en
gageable one with the other without the use of
tools and in a manner that rwill not materially
detract from the front of the display.
Also an object of this invention is the provi
sion of a fabricated action display including shaft
Obviously, an enormous financial
means arranged to be extended if so desired, and
expenditure is required for a single product to
be advertised simultaneously in many different
locations by means of action displays of the char
30 acter heretofore known.
With the foregoing in mind, it is an object of
relatively cheap parts of sheet material which
may be assembled in position to support the shaft
means, counter-balance weights being provided
the present invention to provide action display
Still a furtherobject of this invention is to
provide a fabricated display construction where

structures so economical in character as to War
rant very broad usage thereof.
It is a further object of this invention to pro
vide a motive power unit, which may be standard
in character and adapted for installation in any
of a plurality of action displays of different kinds
and characters.
Also an. object of this invention is the provision
of action display structures which may be read
ily assembled at the ultimate point where the
display is to be provided, in a quick, easy man
ner, without the use of tools.
The invention also contemplates the use of a
substantially standardized motive power unit eas
ily placeable in position, together with a plurality
of cheap, die-cut members of cardboard or the
like which may be readily assembled around a
50 power unit to form an action display of a pre
determined character, the power unit being of
such design that it is adaptable to support and
actuate substantially an unlimited number of
types of displays.
Another feature of the invention is the provi
Where needed on moving parts of the display to 30
lessen the burden on the drive and shaft means.
from a plurality of cheap members of sheet ma
terial, such members being used as ñxed and as
movable parts of the display and also as con
necting rods for actuating the movable parts of
the display, the construction being such that
during operation there is a negligible amount of
wear upon the sheet material itself.
In accordance with the general features of this
invention, a power unit has-been provided in
corporating both driving means, such as an elec
tric motor, for example, and a basic or founda
tion structure for an action display. The power
unit is preferably standardized so that a plurality
of such units may be disposed at Various locations,
each unit being preferably identical in construc
tion and size. The construction of the units is
such that each unit is adaptable to function as a
driving means and basic supporting means of an
action display of substantially any desirable kind,
character or shape. Accordingly, a number of
standardized permanent power units may be dis- .
posed at any desirable points, for example, so
many in one city, so many in another' city, etc.
, When it is desired to place a plurality of action
displays in operation for advertising a certain
product, the various action displays are formed
preferably by die-cutting a, plurality of cardboard
pieces. Each of lthese pieces is so constructed as
to vprevent its being assembled in a display in anyl
except the proper position.

with the shelf I is an upright panel 6 and behind
this panel is an oscillatable panel ‘I divided in the
upper portion thereof into two laterally extend
ing parts 8 and 9, respectively, by means! of a di
I vision notch Il?, as seen more clearly in Figure 3.
Adjacent the lower end thereof, the panel ‘l car
ries a counter-weighted neck portion II to lessen
the load on the power means which oscillates the
panel. With reference to Figures 1 and 3, it will
10" be seen that when the side portion 8 of the panel
l’ is exposed laterally of the panel 6, the side por
tion 9 is immediately behind the panel 6 and so
is invisible from the front of the display. Upon
the next oscillatory movement of the panel l, the
side portion 9 comes into view and the side por
tion li is hidden behind the panel 6.
Behind the oscillatable panel 'I is a relatively
large fixed panel l2 which appears as the back
of the entire display. This panel I2 has an arcuate
the upper portion thereof (Figure
20l opening i3
l) , through which reading matter I4 carried by
a disc l5 is visible. The disc I5 is mounted for
rotation behind the panel I2. It will be seen,
therefore, that the display in general includes
25 six panels having considerable surface upon which
any suitable advertising may be placed, as well
as four separate moving parts. The complete
stand incorporates four different motions, namely,
oscillation in a vertical plane, oscillation in a
30 horizontal plane, rotation in a vertical plane and
rotaton in a horizontal plane. It is also to be
understood that the sign may include as many
moving elements as may be desired and these mo
tions. may be of the character shown or may be
35 disposed obliquely, the kinds of movement and
the direction thereof being substantially un
The standardized power unit and foundation
‘ In the use of the present invention, the power
units, of which one is preferably used for each
display, are preferably as nearly identical as pos
sible. In other words, each unit is of the same
45 size, the housing is of the same general size and
contour, and the upright foundation supports are
also preferably of the same size and disposed
in identical manner in each unit.
It is to` be understood that while I have, in the
50 illustrated embodiments of my invention selected
a type of display which requires the use of only
one of my novel power or motor units, it is fully
contemplated that in other or more complex
types of displays two or more of these units may
55 be associated together to provide for the desired
movements. Also, it should be noted that I have
attained best results by using a power unit which
is so geared that both crank and rotatable drive
elements connected thereto operate at a speed
60 not to exceed 30 R. P. M. or a relatively low one.
The power unit is best seen in Figures 2 and 4.
The unit comprises a suitable form of housing
lli, and in this instance the housing is shown as
being substantially trapezoidal in horizontal
65 cross-section.
As in-dicated by dotted lines in
Figure 2, the housing contains a suitable driving
element, in this instance an electric motor Il, in
cluding a speed reducer, which may be for alter
hating current, direct current or the universal
type. The shaft I8 of the motor projects without
o-f a connecting rod. A vertical shaft 22 (Figure
2) is also disposed within the housing and pro
jects without the housing to support a horizon
tally disposed multi-step pulley 23 also equipped
with a crank arm 24 suitably apertured to- ac
commodate» a thumb nut and bolt connection for
a connecting rod. The shaft 22 is connected with
the motor shaft I8 in any suitable manner, such
as by.a worin gear and pinion. It is to be noted
that it is not essential that the pulley 23 be 10
mounted immediately adjacentthe pulley i9, but
may, if so desired, be disposed at the opposite end
of the housing and geared to the opposite end of
the motor shaft. Current may be supplied to the
motor by inserting a standard form of plug in a 15
receptacle 25 disposed on one of the side faces of
the housing.
To provide a foundation or basic structure for
the display, a plurality of'uprights 26, in this in
stance four, preferably of metal, are associated 20
with the motor housing. The uprights prefer
ably extend to the top of the housing I6 which is
suitably apertured to accommodate them and
rest upon the floor of the housing, the uprights
being held in position by means of transverse
rods 2l? projecting through the uprights in the
side walls of the housing. As seen best in Figure
6, the uprights 26 may each be provided with a
plurality of spaced apertures 28 to afford means
of connection for display apparatus at substan-`
tially any desired location along the uprights.
>It is to be especially noted that the uprights
26 are disposed in such locations and at such
angles that a member shaped for connection to'
a A‘particular pair of uprights will connect with ^
that pair only and will also connect with that
particular pair in only one position, in the event
the top side of the member is kept uppermost
during the assembly. In this particular instance,
each of the uprights are rectangular in cross-sec
tion and have the rear portion thereof disposed
inwardly further than the forward portion. ’in
addition, the distance between the rearinost pair
of uprights is less than the distance between the
forward pair of uprights. By disposing the up 45
rights in this or in an equivalent manner, the
device is rendered fool-proof in that, during the
assembly of the display, the various parts to be
connected to the upright can only be connected
thereto in the correct way. Standardized power
units of the character set forth herein, each in
cluding a housing, a power element therein, suit
able pulleys, and uprights forming a foundation
structure for the display, may be provided in var
ious central locations in any desirable quantity
and kept in these locations. When it is desired
to provide advertising displays of any character,
it is a simple expedient to manufacture various
cardboard parts for the displays, ship these parts
to the points of exhibition, and assemble them 60
around a power unit already located near to the
place of exhibition.
If so desired, illumination may be provided for
certain portions of the signs by means of an
electric lamp 29 connected through a suitable 65
lead 3i) to a socket 3i also associated with the
the housing, and upon the end of this shaft a
motor housing and, as indicated at 32 in Figure
2, any suitable form of make and break contact
equipment may be provided to cause periodic il
lumination of the lamp. This equipment 32 is 70

This pulley
carries a crank arm 20 projecting therefrom upon
the outer end of which is a thumb nur and boit

In most cases, no
locking device or anchoring means are neces
sary, the lower end of the tube merely resting
upon the floor. Mounted for rotation within the
tube 55 is a somewhat shorter tube 56 which is
preferably made of brass or some similar eco
nomical tubing. The tube 56 is journalled with
in the tube
and a multi-step pulley 5l is fixed
ly secured to the upper end of the tube 55 for
10 rotation therewith. The pulley 5l is securely
keyed to the tube 5t, and a suitable plug 5@ may
be pinned in the lower end of the tube 55 to func
tion as a base support for the lower end of the
shaft iii and the tube 56.
The Lipper end of the tube 55 is preferably de
formed as at Sil to ñt around a shaft 5i which
is polygonal in cross section, whereby the shaft
@i will be rotated with the tube 55. The shaft
5i extends through a suitable aperture in the
shelf di and has ñxedly connected thereto a suit
able hanged collar member 62 which carries the
turn-table 2. This shaft 5l is preferably an
inexpensive rod or polygonal wire, and in assem
bling this shaft construction,it is a simple eX
pedient to vary the length of the shaft 5i by
merely snipping off the polygonal wire at the
desired length. Since the wire fits within the
deformed portion of the hollow shaft, it will be
seen that
is very simple to provide `a shaft 6|
of any desirable length.
The operation of the turn-table 2 may be ef
fected by connecting a belt 63 around the pulley
5l and also around the pulley 23 of the power
unit. This belt is preferably merely a piece of
string wrapped around the respective pulleysy and
4 l.
tied in a suitable knot, the knot not interfering
with the operation. The belt 63 (Figure 5)
passes through a suitable aperture 64 in the
frame member ¿S9 and a similar aperture is also
provided in the other channel frame member 53.
Of course, the speed of the turn-table may be ad
justed as desired by merely connecting the belt
to the proper step on the pulleys 57 and 23,
these pulleys being in inverse relationship to each
The laterally oscillatable display element 5 is in
this case mounted directly and fìxedly upon the
rod il which is also polygonal in cross-section. A
shelf construction may be associated with this
50 el" ,nt that is somewhat similar to that asso
l with the turn-table 2.
in this instance, a tubular casing member 65
is utilised which may be identical in construction
and mounting with the tube 55. Within the tube
55 55 is a hollow shaft titi, and nxedly secured to the
upper end of this shaft so as to rotate therewith
plate member Eil (Figures 5 and 14). This
te member has a depending collar 58 which

The connecting rod ‘M is also preferably
made of cardboard and predesigned in the right
length and carrying suitable indicia designating
through which of the apertures "i3 connection is
to be made for the particular display at hand.
The opposite end of the connecting rod lll is at
tached by means of a thumb nut and bolt con
nection to the crank arm 2d associated with the 10
pulley 23 (Figure 2). The connecting rod is pref
erably folded into channel form to increase its
strength, and this connecting rod may be stamped
out of cardboard together with the panel and
frame members. Any suitable form of arrange 15
ment in the thumb nut and bolt connection at
the ends of the connecting rod may be used to
lessen the wear on the connecting rod. The drive
of the display element 5 will be obvious from the
The connecting rod 'M will function
as a pitman, one end of the rod rotating with
the rotation of the pulley 23, and the other end
of the connecting rod causing an oscillation of
the crank arm ‘l2 which in turn results in a lat
eral oscillation of the display element 5 through
the polygonal shaft 4. It will be noted that a
disc and oscillating shelf might also be used on
the shaft It.
Horizontal and oblique shaft construction includ
ing 'eœtension elements and' attaching plates
Tn the present instance, for the particular dis
play` structure illustrated, two horizontal shaft
constructions are necessary, one for operating
the oscillatable member l, and one for operating
the rotatable disc i5. As these shaft construc
tions are substantially'the same in character, it
is only necessary to describe one of them herein
with specific reference to the details of construc
While the shaft constructions for the oscil
latable element l and the disc l5 are both dis
posed horizontally in the present instance, it will
be apparent from the description hereinafter that
such shaft constructions may be mounted in 45
oblique positions, if so desired, with obvious vari
ations in the hubs or bushings in the outer sleeve
of the shaft for connection with the frame and
panel members.
With reference more particularly to Figure 8, 50
it will be seen that a shaft 75 is utilized for oper
ating the oscillatable element l. In this instance,
the shaft ‘i5 is shown in two parts to illustrate
how a shaft may be extended in the event the
shaft is not suñ‘iciently long for the particular
display desired.` For the purpose of clarity, the
part nearest the power unit is designated l5 and
the other part which is connected to the oscil
latable display element 'i is designated 15a.
The shaft part l5 is rotatable within a tube
'iii of brass or some similar economical metal to
form a bearing surface for the shaft. The tube
'l5 in turn may be fixed within a tube ll of any
desirable material, such, for example, as fiber. ‘
At spaced intervals therealong, this tube 'il is pro 65
vided with flanged hubs or bushings for engage
ment with the respective frame and panel mem
bers of the display structure. There is preferably
the same number of bushings as there are frame
and panel members, in this instance one extra
bushing being shown to illustrate the flexibility
of the construction, this yadded bushing being
ready in the event the same shafting construction
is used in a display structure incorporating an
added frame or panel member.

shape of a rivet, as indicated »at |03, to hold
securely in position an operating plate |04 which 45
oscillates with the shaft and collar. The other
side of the envelope |00 is provided with an aper
ture‘of just sufiicient size to receive the project

The clutch 9i, which is used to join the shaft
extension l'âa, to the main part of the> shaft "i5,
the hub l Il, and this aperture is preferably made
sufficiently large to permit the passage there
10 is best seen in Figures 8 and 9.
lThe clutch end
of the shaft portion 15a, is provided with a keyed
collar H28 to which is. attached a plate l it. This
plate l iii may be of any preselected shape, in this
instance being shown as substantially hexagonal
15 with one portion removed along the line iii in
Figure 9 to make,y the plate seven sided, as indi
cated by the full lines in Figure 9. Another plate
H2 of a different irregular shape is similarly at
tached to the adjacent end of the shaft i5. The
20 shape of the plate i l2 in this instance is indi
cated by the dotted lines in Figure 9 except for
that portion of the plate extending beyond the
cut-out portion of the plate MS. Each of these
plates is preferably notched in a plurality of
25 spaced locations, in this ins-tance three, as indi
cated at H3. A pin bolt Hai may be readily
spring 'clip {2i} having a hook 22E projecting
tance below the slot H9.
The frame member 49 must of necessity be
provided with an aperture £23 above the slot for
through of a stepped pulley l2@ secured to the 10
rear end of the shaft (Figures 2 and 3). The
other end of the shaft is connected to the rotat
able disc l5 by means of an attachment connec
tion Sila which is of the same character as the
attachment connection Si! above described.
The flanged hub ll‘l is held in position in the
saine manner as is the hub l i8, but each of these
hubs, together with their respective slots in the
.frame members 49 and 53, are preferably of dif
ferent size to eliminate error in the mounting
of the shaft. The plate upon the end of the shaft
used in the attachment connection Silla is also
preferably of a diñerent shape than the plate
used in the attachment connection 9G for the
same reason.
A beit §25 establishes driving Connection be-v
tween the pulley i9 upon the motor shaft and the
an enlarged rear portion engaged against the
plate I I0 and a narrow threaded portion extend
pulley §24, this belt also being preferably merely
passing through the enlarged ends of the bolts,
35 thus preventing loss of the bolts and permitting
very quick connection of the plates.
The peculiar shapes of the plates upon the ends
of the shaft extension utilized in the display
structure preferably differ so that they cannot be
40 assembled incorrectly. Insofar as the clutch of
the character 9i is` concerned, it is a simple eX
pedient to place the flat» faces of the plates to
gether and secure them in position. However,
each of the plates upon the shaft may be utilized
45 for a connection such as the attachment connec
tion 90, to a movable portion of the display, the
a piece of string with the ends tied together.
In View of the above description, it will be ap
parent that the shafting construction utilized in
the present display structure is of such character
that although mounted in frame and panel mem
bers of cardboard or similar sheet material, there
can be no binding of the shafts themselves due to
warping or misalinement of the frames and
panels, since each shaft is journalled within a
rigid sleeve.
The formation. of a. display of different character
irregularity in the» shapes of the plates prevent
ing attachment of that particular shaft to the
In Figures l5 and 16 I have illustrated how the
present invention may be utilized to provide a dis
play of a different character. In this instance,
only two movements are utilized in the display, an
oscillatory movement in a vertical plane and a
rotary movement in a vertical plane.
In this instance, the same power unit is, of
course, utilized, but nothing will be connected to
Wrong display element.
The connection of the respective plates to each
there is no movement in a horizontal plane in the 50
shaft length may be of the same> character as
illustrated and above described in connection with
Figure 11.
From the above shafting construction, it will
55 be apparent that the structure may be assembled
very expeditiously and without the use of tools.
It will also be` apparent that in the event a central
portion of a movable display element is exposed
to the eye, the outside face of this element will
60 not in any manner be defaced by means of the
connection to a shaft.
With reference now to, Figure 2, it will be seen
that a similar shaft construction is pro-vided for
operation of the rotatable disc i5. In this in
65 stance, no extension length of shafting is nece-s
sary. The shaft construction is the same as that
previously described in connection with the op
eration of the oscillatable element i, including
a shaft l'5b journalled in a metallic tube itil?, in
70 turn fixed within an external tube lib. The tube
‘Hb is provided with a pair `ce’ flanged hubs lli
and H8 for engagement in suitable slots in the
frame members 4.9 and
respectively, (Figures
2 and ’7) . As seen best in Figure '7, the panel 53
and the bushing is held in position by means of a

30 ing through the notch, the bolt being held in posi
tion by means of a thumb nut i i5 placed against
