PROVISIONAL SPECIFICATION.
Improvements in Advertising Apparatus.
I, JOHN GEORGE AULSEBROOK KITCHEN of 28 Rose Grove, Ardwick, Man-
chester in the County of Lancaster, Manufacturer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to that kind of apparatus for advertising in which the
advertisement is displayed on a revolving disc or its equivalent and consists in
improved arrangements or means for rotating said disc or its equivalent.
Ordinarily such discs are rotated by means of clock-work requiring to be wound
up periodically or by small motors worked by water pressure or electricity making
such apparatus costly and inoperative when the winding up is omitted.
The object of my invention is to dispense with clockwork and reduce the cost of
the apparatus. This I effect by utilizing the vibrations of a weight supported by
a spring caused by the vibrations of the ground or buildings, or the vehicles in
which the apparatus is fixed, for rotating the disc or its equivalent.
In carrying out my invention I mount the disc, on the face of which the
advertisement is displayed, on a shaft supported in a suitable frame or casing,
to which I attach a spring carrying a weight at its end. Preferably I use a flat
spring fixed in a horizontal position. To the weight I attach a pawi acting on a
ratchet wheel or its equivalent fixed to the disc, a second retaining pawl being
attached to the casing. If the disc is arranged vertically, for exhibition for
instance in a shop window, the ratchet wheel will be a spur ratchet or equivalent
the spring and weight extending above the same and the pawl resting upon the
circumference of the ratchet. If the apparatas is to be fixed horizontally, for
instance to the roof of a tramcar, I use a crown ratchet wheel or equivalent rim
fixed on the top of the disc, above which the spring and weight are fixed, the pawl
attached to the weight acting on the ratchet at one side. Elastic buffers or india-
rubber pads are arranged above and below the weight to limit its vibrations.
Instead of the weight being attached directly to the spring it may be attached to
a lever held up by a spring.
The vibrations of the weight may be utilized to rotate a circular or polygonal
roller showing advertisements through a slot of the casing, instead of a disc.
Instead of the roller c or disc being rotated directly by the weight and pawl, the
latter may be arranged to act on a ratchet wheel on a side shaft and a single cog
wheel be connected to the ratchet or shaft which drives a star or Geneva stop
wheel fixed to the roller or disc so as to rotate the latter intermittently.

page_text: I, JOHN GEORGE AULSEBROOK KITCHEN of 28 Rose Grove, Ardwick,
Manchester, in the County of Lancaster, Manufacturer, 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 that kind of apparatus for advertising in which the
advertisement is displayed on a revolving disc or its equivalent and consists in
improved arrangements or means for rotating said disc or its equivalent.
Ordinarily such discs are rotated by means of clockwork requiring to be wound
up periodically or by small motors worked by water pressure or electricity, making
such apparatus costly, and inoperative when the winding up is omitted.
The object of my invention is to dispense with clockwork and reduce the cost of
the apparatus. This I effect by utilising the vibrations of a weight supported
by a spring which are caused by the vibrations of the ground or buildings or the
vehicles in which the apparatus is fixed, for rotating the disc or its equivalent.
On the sheet of drawings appended hereunto,
Figs. 1, 2 and 3 show an improved advertising apparatus arranged for attachment
to the roof of a tramcar or other vehicle, in top view and two vertical sections.
Figs. 4, 5 and 6 an improved apparatus arranged for fixing in a vertical position,
in back view, vertical and horizontal section.
On the
In carrying out my invention I mount the disc a on the face of which the
advertisement is displayed on a shaft b supported preferably on centre points in
bearings on the back plate c of the casing and the glass plate d in front of disc a.
To the casing a flat spring e is fixed carrying a weight fat its end.
spring emount a pawl or pawls 9 acting upon a ratchet wheel or its equivalent
fixed to the disc a or shaft b. If the disc is arranged horizontally, as in Figures 1
to 3, I use a crown ratchet wheel or its equivalent. I have found in practice that
it is sufficient to use a flat disc i roughened with radial file strokes or milled with
radial indentures. If the apparatus is to be fixed vertically, for instance for
exhibition in a shop window, a spur ratchet or milled pulley is used, the pawl or
pawls g in each case resting by its weight upon the surface of the ratchet or
equivalent wheel. A second retaining pawl fixed to the casing may be applied.
Elastic buffers or india-rubber pads may be arranged above and below the weight f
to limit its vibrations.
The vibrations of the building, glass pane or vehicle to which the apparatus is
attached cause the weight to descend and the spring to lift it up again, so that the
spring and pawl or pawls vibrate up and down and the pawl propels the ratchet or
its equivalent and rotates the disc.
Instead of a disc, a circular or polygonal roller may be fixed upon the shaft b.
showing advertisements through a slot in the casing, or an endless band with
advertisements may be passed round a roller mounted on shaft b and another
parallel roller and advanced by the rotation of shaft effected in the hereinbefore
described manner.
Instead of the disc or roller displaying the advertisement being mounted on the
shaft b rotated by the vibrations of the weight, they may be mounted on a separate
shaft carrying a star or Geneva stop wheel which is acted on by a single cog wheel
fixed on shaft b so as to rotate the advertisement disc or roller intermittently.
Obviously the weight may be attached to a lever held up by a spring instead to
a flat spring and the pawl mounted upon the lever.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In advertising apparatus, rotating a disc or its equivalent displaying the
advertisement by means of the vibrations of a weight supported by a spring,
substantially as herein before described and illustrated by the drawings.
2. In advertising apparatus the arrangement of a weight fixed to a flat spring
or a lever held up by a spring and a pawl or pawls mounted on said flat
spring lever or weight and acting on a ratchet wheel or its equivalent which is
fixed upon a shaft carrying a disc or roller displaying the advertisement, for the
purpose of rotating said disc or roller, substantially as herein before described and
illustrated by the drawings.
