PROVISIONAL SPECIFICATION left by the said James Osborn Spong
at the Office of the Commissioners of Patents, with his Petition,
on the 14th October 1872.
I, JAMES OSBORN SPONG, of No. 28, King William Street, Strand, in
the County of Middlesex, do hereby declare the nature of the said In-
vention for IMPROVED APPARATUS FOR PRODUCING CHANGES IN REPRESENTATION
ADAPTED TO ADVERTISING AND OTHER USES," to be as follows:-

The object of the Invention is to produce attractive changes in effect
or representation adapted to advertising purposes, and also to afford
amusement or instruction, and for other uses.
In carrying my Invention into effect a wheel of inclined arms or
vanes is supported to revolve in a chamber over a gas or other burner,
the heat from the light of which causes a current of air to be produced,.

which acting on the arms or vanes causes the rotation of this wheel to
give motion to another surface or series of surfaces. For this purpose
pins, teeth, or studs projecting from the periphery of this wheel of arms
or vanes act against corresponding pins, teeth, or studs in the periphery
of another wheel or disc to give rotary motion to such other wheel or
disc, which is supported to revolve in a chamber formed between the
face or front plate of the apparatus, and a glass or other transparent or
semi-transparent "screw" behind it. This revolving dise is formed partly
opaque and partly transparent, or so as to admit light through in form
or in coloring adapted to the effect to be produced, and that portion of 1
the front plate immediately in front of this revolving disc is open in
form or adapted to admit the passage of light to correspond with the
forms in the surface of the disc, or so as to produce the desired changeable
effects. Thus supposing the form in each to be that of a star, by the
one revolving behind the other the effect of a twinkling star will be
produced in color, which may be varied by that of the media through
which light from behind is caused to pass.
In like manner chromotrope and other varying effects may be pro-
duced to draw attention to surrounding advertisements on glass or other
transparent or semi-transparent media lighted from the interior or the
back of the apparatus or otherwise to attract attention.
The relative position of the revolving disc to the front of the apparatus
may be changed, and two or more of such revolving dises may be applied
to operate on the same or other sides of the apparatus.
In place of the motion being imparted to a vertical plate for the
changing effects, changing effects may be obtained by the use of a
revolving cylinder operated in like manner in relation to a stationary
surface.
In place of the revolving wheel giving motion to a disc to cause it to
revolve, it may act upon a series of surfaces to produce the desired
changes in effect.
Also in place of the desired motion being obtained by a current of air
produced by the heat of a burner, it may be obtained by other current
of air or vapour, or by gear from clockwork, or by other motive power.

TO ALL TO WHOM THESE PRESENTS SHALL COME, JAMES
OSBORN SPONG, of No. 28, King William Street, Strand, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me; the said James Osborn Spong, Her special license
that I, the said James Osborn Spong, my executors, administrators, and
assigns, or such others as I, the said James Osborn Spong, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, usc, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVED APPARATUS
FOR PRODUCING CHANGES IN REPRESENTATION ADAPTED TO ADVERTISING AND OTHER
USES," upon the condition (amongst others) that I, the said James Osborn
Spong, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Osborn Spong, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
The object of the Invention is to produce attractive changes in effect
or representation adapted to advertising purposes, and also to afford
amusement or instruction, and for other uses.
In carrying my Invention into effect a wheel or wheels of inclined
arms or vanes is supported to revolve by the action of a current or
currents of air to or from gas or other burner or burners in a chamber,

page_text: the heat from the light of which burner or burners causes a current of
air to be produced, which, acting on the arms or vanes causes the
rotation of this wheel or wheels, and thence gives motion to another
surface or series of surfaces. For this purpose pius, teeth, or studs
projecting from the periphery or parts of this wheel of inclined arms or
vanes act against corresponding pins, teeth, or studs, or parts of or in
connection with the object to be moved, and when that is part of a
wheel or periphery, such wheel or periphery, or disc is supported to
revolve in a chamber formed between the face or front plate of the
apparatus, and a glass or other screen behind it. This revolving disc I
generally form partly opaque and partly transparent, or so as to admit
light through in form or in coloring adapted to the effect to be produced,
and that portion of the front plate immediately in front of this revolving
dise is open in form or adapted to admit the passage of light to correspond
with the forms in the surface of the disc. The forms for the changeable
effects may however be produced on the surface moved so as to produce
the desired changeable effects. Thus supposing the form in each to be
that of a star, by the one revolving behind the other the effect of a
twinkling star will be produced in color, which may be varied by that of
the media through which light from behind is caused to pass.
But that the Invention may be fully understood, I will, by the aid of
the accompanying Drawings proceed to describe means pursued by me in

page_text: wheel c, as indicated more clearly by the separate plan and edge view of
it at Figure 7, is formed with pins or projections c² to be acted upon by
the ends of the inclined arms or vanes e¹ of the wheel e, and it has also
a transparent or semi-transparent centre o³ corresponding in form with
that of b. The wheel e is supported with capability of freely revolving
on the pivot f g and are two gas burners, either or both of which
may be (or there may be other number of them) lighted at the same
time for the purpose of showing light if desired through the transparent
part of the wheel c, and through a glass or other transparent media
at i, and also by their heat causing a current of air to flow through the
apparatus to act upon the arms or vanes e¹ of the wheel e, to give
motion thereto for driving the wheel c.
The glass or other media at i may be passed in or removed through
the opening, and retained by spring catch &; and in like manner
advertising or other effects may be placed at j through an opening j¹ at
one thereof.
is a glass screen, which is supported in grooves k¹
with facility for removal; and are other grooves for the support of
colored glass to give colored effects to the changes if desired. The
screen k serves to prevent too great heat acting on the disc or wheel c,
by the current of air flowing up between it and the front of the
apparatus.
It will thus be seen that by the current of air produced the wheel of
inclined arms or vanese will be caused to revolve, and by the ends of
it acting on the pins or projections c² of the wheel c, that wheel will be
caused to revolve, and the transparent portion c of that wheel corre-
sponding with the open star of the apparatus; as the wheel e revolves
a succession of variations of size of stars, or a twinkling effect will be
produced.
In like manner chromotrope and other varying effects may be produced
to draw attention to surrounding advertisements on glass or other trans-
parent or semi-transparent media lighted from the interior or the back
of the apparatus or otherwise to attract attention.
The relative positions of the revolving discs to the front of the
apparatus may be changed, and two or more of such revolving discs
may be applied to operate on the same or other sides of the apparatus.
In place of the motion being imparted to a vertical plate for the
changeable effects, changeable effects may be obtained by the use of

page_text: a revolving cylinder operated in like manner in relation to a stationary
surface.
In place of the revolving wheel giving motion to a disc to cause it to
revolve it may act upon a series of surfaces to produce the desired
changes in effect.
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that I do not
claim as of my Invention the use of a wheel with inclined arms or vanes
to rotate by the current of air produced by the heat of a burner, when
such wheel is formed on the top of and attached to a cylinder with which
it revolves as one instrument, nor do I confine myself to the precise
arrangement of parts as shewn and described, as the same may be varied
without departing from the peculiar character of the Invention, but
what I do claim is, the arranging or combining parts whereby changes in
representation may be obtained by the rotation of a wheel or wheels
with inclined arms or vanes caused to revolve by the heat of gas or other
burner or burners in a chamber to give motion to other separate parts
adapted to advertising and other uses, and acting substantially as
described.
In witness whereof, I, the said James Osborn Spong, have hereunto
set my hand and seal, this Tenth day of April, in the year of our
Lord One thousand eight hundred and seventy-three
