An Improved Method of Advertising in Passenger Vehicles by
Means of Moving Advertisements.
1, ROBERT WOTHERSPOON of Swanston Street in the city of Melbourne and Colony
of Victoria, Australia, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to appliances or devices for advertising purposes, and is
specially designed for use in combination with Railway carriages tramcars, ships, and
other vehicles plying for passenger traffic.
It consists of one or more revolving or moving appliances or devices on which
advertisements are printed painted or affixed and kept moving by mechanism,
electricity or compressed air. These advertising appliances or devices may be placed
at any position in the vehicle and may take the form of cylinders, rollers, dises, endless
bands, or other approved form so long as the essential feature is retained namely, that
motion is imparted to them either from the wheel or axle or from mechanism or other
motive power carried on the conveyance: Various methods according to circumstances
may be employed for transmitting motion to these advertising appliances or devices
among which the following may be adopted as being automatic in its action, practical
in its application and not liable to get out of order.
On each side of the conveyance I place a long hollow drum or cylinder well out of
the reach of the passengers heads, and held in position by suitable brackets or hangers
fixed to any convenient part of the frame work of conveyance.
On one end of this
drum or cylinder I fasten a ratchet wheel with fine teeth, operated upon by a light
spring paul, hinged or jointed on the top end of a vertical rod, which is held in
position by sockets screwed or otherwise into the end of the conveyance, the lower end
of this vertical rod which extends underneath the floor is formed with a double jaw to
connect with a forked lever attached at one end to a double jaw bracket which is
fastened to the underside of the floor, the other or forked end of lever bears upon an
eccentric cam fastened on the axle. To save friction a light slipper carrying a friction
roller is attached to the upper fork of lever, the roller running on the periphery of
the eccentric which raises the lever sufficiently high to cause the vertical rod by means
of the spring paul to move the ratchet wheel one or more teeth at each lift.

page_text: The novelties of this invention are, increased advertising space inside the conveyance
is thus obtained, the advertisements being in motion either intermittent or otherwise
will attract notice and interest the general public; being automatic it requires no
attention to ensure the advertisements always moving in the one direction relatively
to the conveyance to which it may be attached. Referring to the accompanying
drawings, Figure 1 represents a longitudinal section of a tram car shewing a method
of imparting a revolving, forward motion to the advertising cylinder from the car
axle. Figure 2 is a plan of the same. Figure 3 is a cross section of same. Figure 4
an enlarged view of same. A is the car. B the cylinder or drum. B₁ the ratchet
wheel. C vertical rod. C¹ spring paul, C² sockets, C³ double jaw. D forked lover,
E double jaw bracket.
I friction roller and slipper, G the eccentric cam, H the axle.
The mode of operation is as follows:―
Upon the car being set in motion the eccentric cam G, upon every revolution of
the axle H, lifts the lever D, sufficiently high to raise the vertical rod C enough
to move the ratchet wheel B¹ one tooth forward, and so on, as long as the car
runs.
By this simple contrivance the speed of the drum or cylinder is reduced to half a
turn per minute, or may be regulated to suit any speed whatever and the advertise-
ments will always turn in one direction and consequently suitable for conveniently
being read.
The advertisement appliances or devices might be made in the form of punkahs
and be moved by similar appliance to that shewn and described; or an up and down
motion in a vertical. plane may be imparted.

I ROBERT WOTHERSPOON of Swanston Street in the City of Melbourne and Colony
of Victoria, Australia, Civil 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 appliances or devices for advertising purposes and is
specially designed for use in combination with Railway carriages, Tram Cars, Ships
and other Vehicles plying for passenger traffic-It consists of one or more revolving
or moving appliances or devices on which advertisements are printed, painted, or
affixed, and kept moving by suitable mechanism.
These advertising appliances or devices may be placed at any position in the Vehicle
and may take the form of Cylinder rollers, discs, endless bands, or other approved
form so long as the essential feature is retained namely that motion is imparted to
them either from the wheel or axle. The following method of transmitting motion to
these advertising appliances or devices will be found not only practical in its operation
but automatic in its action and not liable to get out of order :-On each side of the
Conveyance is placed a hollow drum or cylinder well out of the reach of the
passengers' heads and held in position by suitable brackets or hangers fixed to any
convenient part of the framework of Conveyance.
On one end of this drum or cylinder is fastened a ratchet wheel with fine teeth,
operated upon by a light spring paul hinged or jointed at or near the top end of a
vertical rod which is held in position by sockets screwed or otherwise fastened in the
end of the Conveyance.
The lower end of this vertical rod which extends underneath the floor is formed
with a double jaw to connect with a forked lever attached at one end to a double
jawed bracket which is fastened to the underside of the floor.
The forked end of lever bears upon an eccentric cam fastened on the axle. To save
friction a light slipper carrying a friction roller is attached to the upper fork of lever,
the roller running on the periphery of the eccentric cam which raises and lowers the
lever sufficiently to cause the vertical rod by means of the spring paul to move the
ratchet wheel one or more teeth at each rise and fall.
The novelties of this invention are, increased advertising space inside the Conveyance
is thus obtained; the advertisements being in motion either intermittent or otherwise
will attract notice and interest the general public; being automatic it requires no
attention to ensure the advertisements always moving in one direction relatively to the
Conveyance to which it may be attached.
Referring to the drawings accompanying my provisional Specification, Figure 1
represents a longitudinal section of a tram car shewing my method of imparting a
revolving forward motion to the advertising drum or cylinder from the car axle.

page_text: Figure 2 is a plan of the same. Figure 3 is a cross section of the same. Figure 4
an enlarged view of the mechanism for imparting motion. A is the Car, B the
Cylinder or drum, B¹ the ratchet wheel, C the vertical rod, C₁ spring paul, C2 the
sockets, C³ the double jaw, D the forked lever, E the double jawed bracket, F slipper
and friction roller, G the eccentric cam, H the axle. The mode of operation is as
follows: The Car being set in motion the eccentric cam G upon every revolution of
the axle H lifts the lever D sufficiently high to raise the vertical rod C enough
to move the ratchet wheel B' one tooth forward, and so on, as long as the Car
runs.
By this simple contrivance the speed of the cylinder or drum may be reduced to
half a turn per minute, or may be regulated to suit any speed whatever, and the
advertisements will always turn in one direction, and consequently be suitable for
being read conveniently.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declaro that what I
claim is
In a Passenger Vehicle the combination of a revolving drum. or cylinder for
displaying advertisements and of the arrangement of mechanism for operating the said
drum or cylinder substantially as shewn and described.
