An Improved Sign or Advertising Lamp to Command Better
Attraction or Attention.
I, Professor SILANKER ABAJI BISE, F.S.Sc., President of the Bombay Scientifio
Club, residing in Bombay, near Ramwadi, Market Post, do hereby declare the
nature of this invention to be as follows: -
The invention consists of an outer cylindrical casing provided with any suitable
signs, or advertisements, the letters and words of which are cut therein; and an
inner revoluble casing provided with a plurality of transparent or translucent
differently coloured panels or panes, which, the latter, are arranged in such a
manner, that when they are revolved with this inner casing, the letters and words
of the sign or advertisement, will appear, vanish away, and reappear in full, suc-
cessively in the order in which they read. The outer casing is covered with a
conical top, and closed at the bottom, in the centre of which, is fixed a tubular
socket for holding a candle, as well as for supporting the device in the bracket.
The inner revoluble casing is closed at the top, in which radial slits are made to
serve as propellers, or openings for passing the heated gases. It is supported by
a central rod and is made to revolve either by the heated gases or products of com-
bustion produced by the candle and passing through the radial slits made in its
top; or by the action of a small clock work or an electric motor, fixed in the
conical top of the outer casing, with a suitable fan regulator. The outer casing
may be stationery or be made to shift one part or space of its circumference, by
means of the above mentioned mechanism, so as to change the places of signs or
advertisements in such a way, that when the inner casing makes a desired number
of revolutions, it, the outer casing, will only turn one space. The device can be
fixed over the top of a chimney of any ordinary lamp, by boring a suitable hole
in its bottom, in place of the tubular sket, and the heated gases produced by
such lamps can be utilized in revolving the inner casing to produce the desired
effect.
The improved sign or advertising lamp is particularly adapted for use by
shop-keepers as well as by the general public, and is designed to be placed at the
top of a door or lamp chimney, or in a window, halls for public & private gather-
ings, or in any other desired place, for exhibiting signs or advertisements, or any
other information of interest, illustrated by pictures or transparancies, and thereby
easily commanding the attention of passers by road, or persons in a gathering,
until the information or advertisements are read.

I, SHANKER ABAJI BIIISE, of Ramwadi Market Post, Bombay, India, Professor,
F.S.Sc., 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 advertising and sign lamps, and its object is
to provide an improved lamp of this class, having an outer cylindrical casing
and an inner rotatable casing. The outer cylindrical casing is provided with any
suitable sign or advertisement, the letters and words of which are cut therein,
and the inner rotatable casing being provided with a plurality of transparent and
translucent differently coloured panels or panes, which are arranged in such a
manner, that when the inner casing is revolved, the letters and words of the sign
or advertisement will appear successively in the order in which they read and
with these and other objects in view, the invention consists in the construction
combination and arrangement of parts hereinafter described and claimed.
I will now describe the invention with reference to the accompanying drawings,
in which:
Fig. 1 shows a side view of my improved lamp.
Fig. 2, a central vertical section thereof.
Fig. 3, a partial section, similar to Fig. 2, showing a modified form of con-
struction.
Fig. 4, is an elevation of the casing of the inner rotatable casing extended or
opened flat.
Fig. 5, is a similar view of the outer cylindrical casing extended or opened flat.
Fig. 6, is a partial section on the line 6--6, of Fig. 2.
Figs. 7 & 8 show modifications of the same which are described further on.
Referring to the drawings, the numerals indicate similar parts in each figure.
In carrying out my invention, I provide a lamp with an outer stationary cylin-
drical casing, which is provided with a perforated bottom 8, and a conical top 9,
on which is placed a conical cap 10, which is secured to the neck 11, and round
which are ventilating openings 12. Secured to the perforated bottom 8, at one
side thereof is an upwardly directed rod 13, the upper end of which is provided
with an inwardly directed arm 11, having an upwardly directed prong 15, and I
also provide an inner rotatable cylindrical casing 16, which is closed at the top
and open at the bottom, and which is provided centrally with a thimble 17, into
which the prong 15 projects.
The prong 15, of the rod 13 forms a pivotal support for the inner cylindrical
casing 16 and the said casing is free to revolve thereon, and the upper end 18,
of the inner cylinder 16 is provided with radial slits 19 and the material thereof
at one side of the slits is bent upwardly as shown at 20, so as to provide ascape
openings for the heated gases or products of combustion, as they ascend through
the inner rotatable casing, and the form of these upwardly directed bent portions
is such that they form propellers or blades which cause said inner cylinder to
revolve.
This construction is best shown in Figs. 2, 3 and 6.
In Fig. 3, I have shown at 21, a casing in which an electric or clockwork motor

page_text: may be placed for revolving the inner cylindrical casing 16, and connected with
this motor, is a pinion 22, which operates in connection with a gear wheel 23
mounted on the thimble 17.
The motor 21 may be used independently or in connection with the propellers 20
for revolving the inner casing 16, and in Figs. 2 and 3 a candle 24 is used, which
is mounted in a tubular socket 25, which passes vertically through the bottom 8,
of the outer casing 7 and in the bottom of this tubular socket is placed a spiral
spring 26, and connected with the lower end of said tubular socket 25 which sup-
ports the candle, is a bracket arm 27 which may be secured to a wall or other
support by means of a plate 28. Secured to or formed on the bottom 8, of the
outer cylindrical casing 7 is a sleeve 29, through which is passed a set screw 30,
by means of which the lamp may be adjusted on the tubular socket or candle
holder 25.
Any desired form of lamp or illuminating device however, may be substituted
for the candle 24, and other means for supporting the lamp may be substituted
for the bracket arm 27.
In Fig. 4, I have shown the material of the inner rotatable casing extended,
and said casing preferably consists of a sheet of metal or other suitable material,
in which are placed at the left hand end thereof, three coloured translucent panels
or panes 31, 32 and 33. These panels or panes are arranged in a vertical line,
and are coloured green, yellow and red, beginning with the top, and arranged
diagonally on said casing or the material thereof are three other panels or panes 34,
35 and 36 and said panels or panes are coloured yellow, green and red, beginning
with the bottom one.
The bottom pane or panel 34 is arranged adjacent to the red pane 33, in the
left hand coluinn of coloured panels, while the panes or panels 35 and 36 are
arranged in the order named, the last pane or panel 36 being arranged in the
upper right hand corner while the green pane or panel 35 is arranged between the
red pane or panel 36 and the yellow pane or panel 34.
These coloured panels may be composed of any desired material, paper or glass
being preferred and the casing in which they are placed may be composed of
metal, cardboard or any other preferred material.
In Fig. 5, I have shown extended or opened flat, the material of the outer
stationary casing 7, or the sheet of which it is composed, and this casing is com-
posed of metal or glass. Arranged thereon in vertical lines, in the spaces 37, 38,
39 and 40 are the words of the advertisement or signs which it is desired to display.
The letters of these words are cut through the material of the casing, or when
a glass casing is used, left blank or open in painting the surface with any opaque
colour and it will be understood that in the operation of the device, the inner
casing is revolved from left to right, and as it slowly turns the letters of the first
word of one of the signs will appear successively in red, the letters of the
next word in green, and the letters of the last word in yellow, and then all the
words will appear at once in green, yellow and red, and as the said inner cylinder
continues to revolve, each of the signs or advertisements, the words of which are
arranged in vertical lines in the outer casing will appear in the same order, the
letters of the upper word first appearing successively in red, the letters of the
second word then appearing successively in green and the letters of the last word
in yellow, and then all the words in green yellow and red.
In the first stage the top word of an advertisement will commence to appear in
red letters, and not until it is completed and subsequently vanished away, will
the second or lower word appear in green letters, and not until this second word
has disappeared after completion, will the third or lest word appear in yellow
letters, but in the second stage all these words will appear at once in a different
colour from that in which they appeared first. At the side of, or between these
words small transparent pictures illustrating the thing advertised may be put
for better attraction.
Referring to Fig. 7 the perforated bottom 8 and the top 9 are joined by four

page_text: upright rods 41. The tubular candle socket 25 instead of holding a candle will
serve to hold the lamp in the bracket 27. The outer casing 7 containing the
advertisements, instead of being stationary will be free to revolve on a pin 42
fixed to the centre of the bottom 43.
The pin 42 moves freely in a socket 44 having preferably a small piece of glass
at the bottom, to overcome friction and fixed in the centre of the bottom 8.
Through the centre of the top 18 of the inner rotatable casing 16 a hard wire
rod 45 should be inserted. The lower end of this rod which projects a little
longer than the lower edge of the casing 16 moves in a socket 46 similar to 44
which is fixed in the centre of the bottom 43 of the outer casing. At right angles
to the rod 45, a cross piece of wire 45* may be attached inside the casing 16 to
make it firmer. The upper end of the rod 45 is firmly attached to the top of the
inner casing at 491 and passes through the bracket 47 fixed to the top 9 and to
this end the gear wheel 23 is rigidly fixed for being turned by the power wheel 22.
To the centre of the upper end of the outer casing 7, is fixed a sleeve 48 having
a gear wheel which revolves around the rod 45. A power wheel 49 having only 3
or 4 teeth projecting from the clockwork or other motor 21, will turn the sleeve 48
with its gear wheel in such a way that when the inner casing makes 4 or 5 revolui-
tions or more if so desired, it will turn the outer casing only one space to change
only one advertisement at a time, that is to say to shift the front advertisement to
one of the sides and to bring the side one in front automatically.
A piece of candle or a lamp 50 is placed near the socket 46 to throw light in
the inner casing 16 and to assist in revolving it by means of its heated gas or
products of combustion passing through the radial slits or propellers 19 in the
top of the casing 16, and which is directly rotated by gear from the clockwork or
other motor above it.
The slits may be increased in number or length or cut to the full length and
the outer end twisted upward like the sails of a wind mill for better propulsion.
In the side of the bottom 43 a hole 51 sufficiently large to admit a hand should
be made, and in the side of the bottom 8 a trap door of similar size should be
made to pass a hand inside the casing 7 to ignite the candle or lamp 50. To
one of the pinions of the clockwork, or to the end of the rod 45 projected outside
the cap 10, a fan 53 of suitable size may be attached to regulate the speed of the
revolution of the inner casing 16. The fan may be ornamented with pictures on
its exterior.
Referring to Fig. 8 a modification of the same lamp is shown fitted to an
ordinary lamp chimney top by making a suitable hole in the bottom 8 of the
casing 7. A socket 46 is fixed over a bent piece of wine attached to the bottom 8.
The lower end of the central rod 45 revolves in the socket 16 and its upper end is
passed through the sleeve 48 and on this rod the inner casing is rigidly fixed
at 18. The heated gases emitted from the chimney will rotate the inner casing 16.
The construction being very simple, such devices can be used over ordinary lamps
kept in halls or windows and in case of patherings or other ceremonies the name
ot such gatherings, or the words "w.leome ad the legends may be put upon
the outer ea ing instead of advertisement.
My improved lamp is particularly adapted for use by shop heepers as well as
the general public and is designed to be placed in a window or at the top of a
door or over a lamp in a hall for gatherings or any other desired place, and it
will be apparent that any desired sign or advertisement may be exhibited thereby,
all that is necessary being to cut or paint the desired signs in the manner shown
and described, in or over the outer casing, the panels or panes of the inner rota-
table casing being coloured in any desired manner. It will also be apparent that
many of the colours may be employed besides those mentioned, and many other
changes in and modifications of the construction herein described may be made
without departing from the spirit of my invention or sacrificing its advantages.
My improved sign is attractive and well adapted to command attention, until the
advertisements on the casing are read.
