PROVISIONAL SPECIFICATION.
Apparatus for Advertising by Means of Electric Lamps.
I, WILLIAM FALCONER KING, of Rosebank Electric Works, Edinburgh, North
Britain, Engineer, do hereby declare the nature of this invention to be as
follows:
My invention consists in the arranging of two or more sets of incandescent electric
lamps so as to represent in succession when rendered luminous two or more words,
sentences, or devices. Each word, sentence or device is controlled by a separate
electric circuit, and each group of lamps forming the word, sentence, or device is
rendered luminous in the desired succession by connecting the electric leads
belonging to the particular group to an appropriate generator of electricity by
means of a suitable commutator driven by hand, clockwork, or any other suitable
source of power in such a manner that the words, sentences or devices will become
luminous in succession, and so convey to the public the information desired by the
advertiser.
The several groups of lamps forming the word, sentence, or device may be
superimposed on one another on the same board, and those lamps which are common
to two or more of the separate words sentences or devices may be used for each
word sentence or device of which they form a part.
Dated this 22nd day of January 1894.

Apparatus for Advertising by Means of Electric Lamps.
I, WILLIAM FALCONER KING, of the Firm of King & Co., Prince Regent
Street, Leith, North Britain, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention consists in the arranging of two or more sets of incandescent electric
lamps so as to represent in succession when rendered luminous two or more words,
sentences or devices. Each word, sentence, or device is controlled by a separate
electric circuit, and each group of lamps forming the word, sentence, or device is
rendered luminous in the desired succession by connecting the electric leads
belonging to the particular group to an appropriate generator of electricity by
means of a suitable commutator driven by hand, clockwork, or any other suitable
source of power in such a manner that the words, sentences, or devices will become
luminous in succession, and so convey to the public the information desired by the
advertiser.

page_text: The several groups of lamps forming the word, sentence or device may be
superimposed on one another on the same board, and those lamps which are common
to two or more of the separate words, sentences or devices may be used for each
word, sentence, or device of which they form a part.
The accompanying drawing illustrates the method of carrying out my invention,
in which two circuits of electric lamps are employed. The lamps (represented by
circles) enclosed in the full lines are joined up in one circuit, and form the
word "Empire," and the lamps enclosed in the dotted lines are joined up in
another circuit and form the word "Palace." The leads belonging to each circuit
are joined to an electric generator or to the street mains of a central station by
means of a suitable commutator or switch driven by hand, clockwork, or other
source of power in such a manner that the current will be applied to the circuits
alternately; thus the words "Empire" and "Palace" will show up alternately at
the same place.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I am aware
of the Specification of Letters Patent No. 7094 of 1890 granted to Alfred Réné
Upward, and I wish it to be understood that I do not claim anything described
and claimed therein, but what I claim is :-
The arrangement of two or more circuits of ordinary incandescent lamps, which
by means of a commutator or switch are rendered luminous in succession and
produce a series of words, sentences or devices at the same place.
