PROVISIONAL DE MOIFICATION.
Apparatus for Moving Advertising Devices.
I, JOHN OWENS ROGERS, of 22 William Street, South Belfast, County Antrim,
Ireland, Advertising Agent, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus whereby I utilise the heat of a gas or lamp
flame for the purpose of moving drums or other devices having marked on them
designs or phrases for advertising.
For this purpose, in the glass or other chimney above the flame I mount a light
wheel having inclined vanes and arranged to work by worm gearing a wheel the
axis of which is connected by any suitable gearing to a drum or to several drums
having on their faces the desired designs or phrases. These drums may thus be
caused to revolve slowly and continuously presenting successive parts of their
surfaces to view, or, by means of cranks eccentrics or cams, they may receive
reciprocating motion, turning partly round and back again, the gearing being
preferably so arranged that the turning movements are effected rapidly with
intervals of rest between these movements. Instead of drums, continuously
revolving or reciprocating discs may be employed, or screens may be successively
brought into view like the photographs in a stereoscope.

COMPLETE SPECIFICATION.
Apparatus for Moving Advertising Devices.
I, JOHN OWENS ROGERS, of 22 William Street, South Belfast, County Antrim,
Ireland, Advertising Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to apparatus whereby I utilise the heat of a gas or lamp
flame for the purpose of moving drums or other devices having marked on them
designs or phrases for advertising.
For this purpose, in the glass or other chimney above the flame I mount a light
wheel having inclined vanes and arranged to work by worm gearing a wheel the
axis of which is connected by any suitable gearing to a drum or to several drums
having on their faces the desired designs or phrases. These drums may thus be
caused to revolve slowly and continuously presenting successive parts of their
surfaces to view, or, by means of cranks, eccentrics or cams, they may receive
reciprocating motion, turning partly round and back again, the gearing being pre-
ferably so arranged that the turning movements are effected rapidly, with intervals
of rest between these movements.
Instead of drums, continuously revolving or reciprocating discs may be employed,
or screens may be successively brought into view like the photographs in a
stereoscope.
Fig. 1 of the accompanying drawings is an elevation and Fig. 2 is a vertical
section of an advertising pillar according to this invention.
Fig. 3 is a sectional plan to an enlarged scale on the line ab of Fig. 2.
Within a column A burns a gas light B causing a current of heated air and
combustion gases to ascend this column, and act upon the inclined vanes of a

page_text: wheel C. A worm on the vertical spindle of this wheel gears with a worm wheel D
causing it to revolve slowly.
A pin or crank on this wheel or on its spindle acting on pallets on a lever E,
causes it to reciprocate, pulling first the one way then the other a cord attached to
the opposite ends of a wire G. This wire is linked to pins projecting from a
number of drums F mounted within a space S near the head of the column.
These drums, which have letters or other designs on their peripheries, as they
are thus caused to turn partly round to and fro, present through the front of
the space. S (which may be glazed) the words or other designs intended to be
displayed.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Apparatus for moving advertising devices, consisting of a series of drums with
letters or designs on their peripheries caused to revolve by gear worked by a
wheel with inclined vanes acted on by the ascending current from a gas burner,
substantially as described.
