COMPLETE SPECIFICATION.
An Improved Vehicle for Advertising Purposes.
We, JOHN JOSEPH HARRISON, Engraver on Wood, and WALTER HOOKER,
Architect, both of 79 New Oxford Street, in the County of Middlesex, 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:—
The object of this invention is to provide a vehicle for advertising purposes
so arranged and constructed that the advertisements carried thereby are con-
tinuously moved so as to be successively exposed, so long as the vehicle is in
motion.
In carrying out this invention we provide a vehicle the body of which is suitably
shaped to contain a horizontal cylindrical drum carrying upon its ends and periphery
a number of advertising tablets suitably secured thereto. This drum is mounted
upon a horizontal rotating shaft, which also carries a ratchet wheel with which
engages a pawl carried by a vibrating lever and by means of which the said drum
is intermittently rotated to successively expose the different advertisement tablets
behind suitable openings in the body of the vehicle. The said vibrating lever is
actuated by means of a crank and connecting rod the said crank being formed on
one of the axles of the vehicle or geared thereto to rotate at a suitable speed. The
end of the vibrating lever is extended towards the ratchet wheel to act as a stop to
the same between each of its movements.
And in order that our invention may be more fully understood and carried into
practice, we will now proceed to describe the same with reference to the accom-
panying drawings in which similar letters indicate corresponding parts in all the
figures.
Figure 1 shews a partial longitudinal vertical section; Figure 2 a rear elevation,
and Figure 3 a transverse vertical section, of an advertising vehicle constructed
according to our said invention.
Like parts are indicated by similar reference-letters in all the figures.
The vehicle body a is shaped as shewn to contain the cylindrical drum carrying
upon its ends and periphery advertising tablets c suitably secured thereto. This
drum bis mounted upon a horizontal rotating shaft d which also carries the
ratchet wheel e with which engages the pawl f carried by the vibrating lever g by
means of which the drum bis intermittently rotated to successively expose the
different advertisement tablets c behind suitable openings in the body of the
vehicle a. The lever g is actuated by means of the crank disc j and connecting
rod the said crank disc being rotated through the chain gearing by the
movement of the wheels m of the vehicle. Such gearing is suitably arranged so as
to actuate the advertisement roller b at a convenient speed. The end of the
lever g is extended at n towards the ratchet wheel to act as a stop to the same
between its successive movements, by which means the rotation of the drum b is
stopped each time a tablet c comes behind one of the openings h.
It is obvious that two or more advertising drums constructed and actuated as
described may be arranged upon one and the same vehicle.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
(1) In an advertising vehicle the combination of the rotating cylinder b with
the body of the vehicle a substantially as herein described and illustrated in the
accompanying drawings.

page_text: (2) In an advertising vehicle, the combination of the extended end n of the
lever with the ratchet wheel e whereby the latter is locked substantially as herein
described and illustrated in the accompanying drawings.
