page_text: I, ALFRED CECIL WRIGHT, of 99 Bristol Road, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to the manner in which I construct advertising
appliances, the object of my invention being to enable a lamp to be employed for
the purpose of illuminating a screen having any desired announcement placed
thereupon, the light being conveyed through coloured glass or other transparent
substance in such a manner as to produce a variety of colours upon the same tablet
or disc and thus by the changing of colour or alteration in the ornamental display
produced to attract attention to the advertisement.
In carrying my invention into effect I construct my advertising apparatus in one
convenient manner in the form of a lamp having a projecting funnel, the outer end
of the funnel being arranged to receive a disc of glass or other suitable material on
which the announcement is displayed. I make my funnel with its outer opening of
any required configuration, although I find it particularly convenient to manu-
facture it in the form of a cone having the base or larger portion of the cone at the
outer extremity. At the inner end of the cone I provide a lens or series of lenses
for focussing the light on to the tablet and for convenience in packing I make
my cone or disc carrier detachable from the mouthpiece of the lantern.
The body of my lamp or lautern 1 make of any suitable configuration of metal
or other suitable material having a hood and a door or doors arranged thereupon in
the manner common to ordinary lanterns used for general purposes, but within the
well or inner portion of the lantern body I arrange a burner with shield or chimney
for enclosing the flame, the burner being made suitable either for gas, electricity,
petroleum, candle or other illuminant. About the candle holder or about the
chimney of the burner I mount a cylinder containing a number of different coloured
glass plates or plates of different colour made of other suitable transparent material.
This cylinder I carry by means of a pivot mounted upon a bearing or standard
arranged within the body of the lamp, the pivot being made with a hardened steel
point and having a similarly hardened footstep bearing or a bearing or centre piece
of agate or other suitable material to permit of as far as possible the minimum
amount of friction being set up when the spindle and its attached cylinder revolves.
At the upper end of the frame forming the cylinder or the casing carrying my
coloured transparent plates I mount a series of vanes or inclined plates in the form
of a fan or in the form of a blade propeller the blades being inclined and formed
with such an angle as will enable the issuing heat currents from the top of the
chimney or above the guard of the burner to set the framework in motion as they
escape. I make my disc plates or blades of metal, mica or other suitable material
and the framework for carrying my cylindrical or other shaped glass as light as
possible so that when the lamp or light is burning the cylinder or framework with its
plates shall revolve and thus cause a different colour to be presented to the front of
the burner and a different colour consequently to be displayed upon the adver-
tising plate as the discs or plates of that colour are carried past the front of the burner
set in motion by the heat escaping from the top. I place behind my burner and
within the barrel or cylinder of plates, a reflector of the ordinary kind. The
bottom portion of the lamp body I make with feet or flanges for standing or being

page_text: attached to any particular stand, or I provide it with legs of any ordinary character
for enabling it to be placed in position in a shop window or other place necessary
for displaying the same.
I provide within my lamp body necessary plates and slides for permitting the
burner or burners to be withdrawn for cleaning or for examination, and I make the
bases or frame of my lantern body suitable when so required for carrying discs or
plates or for carrying other articles which may be necessary for storage.
When making my lamp suitable for burning gas I make an ordinary hose con-
nection or I place a tap or junction piece of any usual character for enabling a
connection at once to be made to a pipe or branch as may be desired.
Instead of making my cylinder or barrel of glass or other transparent material
to revolve by means of the escaping products of combustion I sometimes cause it to
move round by clockwork, the cylinder or barrel being mounted so as to surround the
burner as hereinbefore described when the heat currents alone set the barrel in
motion.
I do not limit the application of my invention to lamps having bodies, burners or
funnels of any particular shape, or fittings of any special type, but I employ the
same essential features of a revolving barrel or cylinder containing different
coloured glass or other transparent plates with an inner burner or light so as to
cause a reflection of a different coloured beam of light to come upon the same
outer disc or plate as herein before described when employing heat currents alone
to set the plate cylinder or barrel in motion.
Dated this 28th day of June 1894.

I, ALFRED CECIL WRIGHT, of 99 Bristol Road, in the City of Birmingham,
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 has reference to the manner in which I construct lamps for
advertising appliances, the object of my invention being to enable a lamp to be
employed for the purpose of illuminating a screen having any desired announce-
ment placed thereupon, the light being conveyed through coloured glass or other
transparent substance mounted upon a cylinder in such a manner as to automatically
produce a variety of colours upon the same tablet or disc and thus by the changing
of colour or alteration in the effect produced to attract attention to the
advertisement.
In the accompanying sheet of explanatory drawings
Figure 1 is a front elevation of my lamp and Figure 2 is a sectional side elevation
of the same.
Figure 3 is an enlarged elevation of my glass cylinder and vanes, and Figure 4
is a plan of the same.
Figure 5 is an enlarged elevation of my burner reflector and bracket, and
Figure 6 is a diagrammatic section showing the manner in which the light is
projected on to the screen, and another form of burner I sometimes employ.
In carrying my invention into effect I construct my advertising apparatus in
one convenient manner in the form of a lamp having a projecting funnel A, the
outer end of the funnel being arranged to receive a disc of glass or other suitable

page_text: material on which the announcement is displayed. I make my funnel with its outer
opening of any required configuration, although I find it particularly convenient to
manufacture it in the form of a cone having the base or larger portion of the cone
at the outer extremity. At the inner end of the cone I provide a lens C or series
of lenses for projecting the light on to the tablet B, and for convenience in packing
I may make my cone and tablet carrier detachable from the mouth piece and
body D of the lantern.
The body D of my lamp I make of any suitable configuration of metal or other
suitable material having a hood E and a door or doors arranged thereupon in the
manner common to ordinary-lanterns_used for general purposes; but within the
well or inner portion of the lantern body 1 arrange a burner G sometimes pro-
viding it with a shield or chimney for enclosing the Hame; the burner I make
suitable either for gas, electricity, petroleum, candle, or other illuminant. About
the candle holder or about the chimney of the burner I mount a cylinder H
containing a number of different coloured glass plate or plates h, h¹, h², h³, of
different colour made of other suitable transparent material. This cylinder H
I carry by means of a pivot K, which works upon a bearing or standard L arranged
within the body of the lamp the pivot K being made with a hardened steel point
and having similarly hardened foot-step bearing or a bearing or centre piece of
agate or other suitable material to permit of as far as possible the minimum amount
of friction being set up when the spindle K and its attached cylinder H revolves. At
the upper end of the frame forming the cylinder or the casing carrying my coloured
transparent plates I mount a series of vanes or inclined plates M in the form of a
fan or in the form of a blade propeller, the blades being inclined and formed with such
an angle as will enable the issuing heat currents from the top of the chimney
or above the flame of the burner to set the frame-work in motion as they
escape, thereby causing the transparent cylinder to revolve. I make my vane
plates or blades of metal, mica, or other suitable material and the frame-work H for
carrying my cylindrical or other shaped glass or transparent plates as light as
possible so that when the lamp or light is burning the cylinder or frame-work with
its plates shall revolve and thus cause a different colour to be presented to the
front of the burner and a different colour consequently to be displayed upon
the advertising plate as the discs or plates h, h', h³, h³, of that colour are carried past
the front of the burner set in motion by the heated air escaping from the top. I
place behind my burner and within the barrel or cylinder of plates, a reflector N of
the ordinary kind used in lamps employed for other purposes. The bottom portion
of the lamp body I make with feet d or flanges for standing or being attached to
any particular stand, or I provide it with legs of the ordinary character for enabling
it to be placed in position in a shop window or other place necessary for displaying
the same.
I provide within my lamp body necessary plates and slides for permitting the
burner or burners to be withdrawn for cleaning or for examination, and I make
the bases or frame of my lantern body suitable when so required for carrying the
advertisement discs or plates or for carrying or other articles which may be
necessary for storage.
When making my lamp suitable for burning gas I make an ordinary hose
connection or I place a tap or junction piece of any usual character for enabling a
connection at once to be made to a pipe or branch as may be desired.
I do not limit the application of my invention to lamps or lanterns having bodies,
burners, or funnels of any particular shape, or fittings of any special type, but
I employ the same essential features of a transparent barrel or cylinder containing
different coloured glass or other transparent plates, which is automatically set in
motion by the heat currents from an inner burner or light so as to cause a reflection
of a different coloured beam of light to fall upon a lens and then to be focussed upon
the outer advertisement screen disc or plate as hereinbefore described to suit any
particular requirement.

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. The combination of a cylinder or barrel carrying different coloured trans-
parent plates and having vanes or turning blades mounted thereon, with a burner,
and a reflector, a lens and an outer advertising plate, screen or disc to form a lamp
or lantern for causing an alteration in the colour or effect upon the advertisement
plate or screen, substantially as hereinbefore described.
2. The construction and arrangement of an advertising lantern having a reflector
and a lens, for throwing light on to an advertisement plate or screen, substan-
tially as herein before described and as illustrated in the accompanying drawings.
Dated this 22nd day of March 1895.
