Improvements in and relating to Advertising Devices.
I, FRANK SEPTIMUS DEVONTEAUX SCOTT, residing at 25 Upper Bedford
Place, Russell Square, in the County of London, England, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to displaying movable advertisements on vehicles, such as
omnibusses, tramcars carts and the like.
My first improvement consists essentially of suitably securing either inside or
outside the vehicle, and in a convenient position, two drums or rollers, upon one of
which is wound a strip of canvas, transparent parchment, or other suitable
material, containing a number of advertisements, whilst to the other is attached the
loose end of said strip, so that when the drum is revolved the strip will wind upon
it, consequently, on said strip between the drums, will be displayed the advertise-
ments, which, as the drum revolves are constantly changing until the entire strip
is again wound upon the first mentioned drum, thus a continuous display of say
different advertisements can be produced. Said strip may be of any suitable
length and can be arranged to travel either around the vehicle or up and down
each side.
Instead of said strip being wound upon the drums as described the ends can be
joined together to form an endless band, and arranged to travel around the drums.
The second improvement refers to mechanism employed to effect the continuous
or intermittent rotation of said drums or rollers, and consists in attaching to the
hub of one of the vehicle wheels a toothed ing to engage with a corresponding
wheel secured upon the lower end of a vertical rod, which extends to the upper
part of the vehicle and carries suitable gearing for imparting a rotary movement
to the said drums the speed of which can be regulated by the arrangement of
intermediate wheels actuated by a small arm.
When the strip, first mentioned, containing the advertisements has been run off
one drum and wound on to the other, it is necessary, at this point, to automatically
throw the wheels, which drive the now full drum, out of gear, at the same time
put into gear, the wheels which drive say the empty drum, so that the said strip
may be again wound upon it.
It may be here explained that the above mechanism can be used with equal
result for rotating any other form of advertising medium capable of being revolved
when applied to a vehicle, such for instance as a hexagon cylinder having
advertisements on or attached to the flat portions thereof.
Dated this 21st day of November 1895.

I, FRANK SEPTIMUS DEVONTEAUX SCOTT, residing at 25 Upper Bedford
Place, Russell Square, in the County of London, England, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
This invention relates to the arrangement on a vehicle of a movable strip of
calico, transparent parchment or other suitable material, containing a number of
advertisements. The ends of said strip are wound upon drums or rollers, placed
preferably in close proximity to each other, whilst on that portion between the drums,
which is extended along the vehicle will be displayed the advertisements, which as
the drums revolve are continually changing until the entire strip is run off one drum
on to the other, at this point or after a momentary stoppage, the now full drum is
automatically thrown out of gear and the empty drum is put into gear so that the
strip can be again wound upon it.
But in order that the invention may be better understood, reference is made to
the accompanying sheet of drawings, in which
Figure 1, illustrates an elevation of an omnibus shewing the proposed position of
the advertising strip and mechanism for operating same.
Figure 2, is a front view of the mechanism for imparting a continuous
movement to the strip containing the advertisements when the drums or rollers
are revolved.
Figure 3, is a plan of same.
Figure 4, is also a plan but with the upper plate removed.
Figure 5, is a side view.
Figure 6, shews the gear for driving the mechanism above referred to.
Figure 7, is a sectional detail view.
Similar letters of reference indicate like parts where they occur throughout the
views.
In carrying out the invention I arrange either inside or outside the vehicle, and
in the most convenient position, two drums or rollers (A) and (A'), mounted loosely
upon spindles (B) and (B) supported by the upper and lower plates (C) and (C¹),
of a suitably shaped frame (D). To cach drum is attached one end of a strip (E)
of calico, transparent parchment or other suitable material, containing a number of
advertisements. Said strip may have elastic or other spring ends and may be of
any suitable length, according to the number of advertisements it is desired to
display each end portion of said strip is wound upon its respective roller, whilst
the portion between the rollers is carried either around the vehicle, inside and
outside or along each or both sides or it can be arranged in any other suitable
position.

or
In order to impart a continuous or if desired intermittent rotation to these drums,
or rollers so that the end portions of the strip (E) will wind first upon one roller
and then when this roller is say full, wind upon the other roller, I secure to the
roller spindles (B) and (B) the toothed wheels (F) and (F1) both of which gear
with a similar wheel (G) loosely mounted upon the spindle (G') on which is also
fixed a cam (H) having a peculiarly shaped circumferential groove (H'). Two
clutch sleeves (I) and (1¹), each baving a tooth or projection (J), are arranged
upon the spindles (B) and (B), and are caused to slide either up or down, to
engage, or be disengaged from the clutch racks (K) and (K¹) formed on the upper
ends of said rollers (A) and (A¹), by means of the levers (L) and (L'), one end of
which are pivotted to the brackets (L') and (L2) and on the other end are formed

page_text: on the
the pins (L) and (L³) to engage the groove (H¹) in the cam (H). The
levers (L) and (L') embrace and connect with loose collars situated
sleeves (1) and (I') so that said sleeves can rotate with their respective spindles,
and the springs (LA) may be used to facilitate the disengaging of the clutches.
To regulate the speed of the cam (H) so that, one drum shall not be put into
gear until the strip is entirely run off same, and the other or full drum
simultaneously thrown out of gear, I arrange beneath the upper plate (C) a ratchet
wheel (M) having a suitable number of teeth and provided with a spring pawl (M²)
to prevent any backward movement, this wheel (M) is rotated by an arm (M')
secured to the roller spindle (B) so that at each revolution of said spindle (B) this
arm strikes a tooth of the ratchet wheel and slightly turns it. To the spindle of
this ratchet wheel is also secured an arm (N) which in like manner, rotates another
ratchet wheel (N') attached to the cam spindle (G). It will be understood that
according to the length of the strip (E) and the speed at which the advertisements
are required to move, so it would be necessary to increase the number of ratchet
wheels proportionately.
When the strip (E) has run off either roller, it momentarily stops until the next
tooth of the ratchet wheel (N) is moved by the striking arm (N).
To effect the rotation of said drums or rollers, I attach to the hub or other
convenient part of one, or if necessary more than one, of the vehicle wheels
(preferably the rear ones) a toothed ring or wheel (O) to engage with a corre-
sponding wheel (O¹) connected with the lower end of a vertical rod (P) which is
suitably supported by the brackets (P¹) and bearings (P), and extends to the
upper part of the vehicle, and carries on its end a toothed wheel (Q) which imparts
a rotary movement to the wheel (G) on the cam spindle aforesaid, through the
medium of the wheel (Q¹).
To the vertical rod (P) is secured a ratchet wheel (R) the spring pawl for
which, is secured to the wheel (Q), which is arranged loosely ou said rod, so that
the mechanism for rotating the rollers carrying the advertising strip (E) will only
be put into operation when the vehicle is going forward.
To allow for any vibratory or other movements of the vehicle when going, so
that the driving wheels (O) and (O¹) shall be always in gear, I form upon or
attach to the bevel wheel (O¹) a sleeve (S) to receive the lower end of the vertical
rod (P). This rod connects with said sleeve by the pin or other suitable
projection (S) which is free to move either up or down in the slot (S), according
to the movement of the vehicle.
In arranging the advertising strip E say for example along the upper portion of
an ominibus, over the windows as shewn in Figure 1, I attach to the drum (A) one
end of the advertising strip (E) which I then carry along and pass over a pulley
or reel, situated at one extremity of the preferably glass panelled frame in which
the advertisements appear. The strip (E) is now brought inside the vehicle, and
after being carried over another pulley or reel at the other extremity of said frame
13 connected at its now free end to the drum (A') and the loose portion of said
strip wound upon it.
When the vehicle is set in motion the drums or rollers (A) and (A¹) are
caused to rotate and the strip, or the portion of it that can be wound, passes from
one drum or roller over the pulleys or reels on to the other drum or roller
consequently displaying in succession any suitable number of say different
advertisements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1st. In advertising devices the combination with the strip (E), of mechanism to
impart a backward and forward movement to said strip, consisting of the drums or
rollers (A) and (A¹) mounted loosely upon the spindles B and B' carried by the
frame D the toothed wheels (F), (F¹) and (G), cam (H) levers (L) and (L'),

page_text: clutch sleeves (1) and (1¹) clutch racks (K) and (K'), suitable mechanism con-
nected with the spindles B for rotating the cam H and suitable driving gear
substantially as herein described and as illustrated.
2nd. In advertising devices, the combination with the cam (H) and mechanism
connected therewith of speed regulating gear, consisting of the ratchet wheels and
striking arms such as (M) (M') and (N) (N¹), arranged to rotate said cam at a
predetermined speed so that one drum shall be thrown out of gear and the other
almost simultaneously put into gear when the strip has run off either drum or roller,
substantially as herein set forth and as illustrated.
3rd. An advertising device having a movable strip (E) containing a number of
advertisements, which are caused to be displayed successively in a frame on a
vehicle, by the mechanism and gear all combined and arranged as herein fully
explained and as illustrated.
