page_text: CHARLES RALEIGH, Mechanical Engineer, Office 46, 58, Chancery Lane,
London, do hereby declare the nature of this invention to be as follows:
My improvements relate to in-operative monogrammic sign-boards, capable
of representing any words, figures, or signs, outlined by incandescent lamps or
discs.

A series of "frames" are arranged according to the maximum number of
letters or the like that it is desired to represent at one and the same time, each
"frame" containing a monogrammic alphabetical design composed of lamp-
holders, of any suitable shape,-the terminals of which are connected direct
to a source of electricity. Each "frame" can be made to represent in outline
any letter, number, or sign, included in the monogrammic design, by inserting
the necessary incandescent lamps in the lamp-holders pertaining to the letter,
figure, or sign, it is desired to produce-the sign being in-operative until the
lamps are inserted. For daylight presentation, instead of lamps suitably shaped
and colored dises may be employed and disc holders or clips take the place of
lampholders.
The discs may be of different color to the background and may be constructed
of any suitable material, such as looking glass, cut or moulded glass, and be
illuminated by reflected light.
The incandescent lamps may be partly painted or otherwise marked to render
them more conspicuous when not illuminated, and the lamps may be of different
size, shape or color, and be provided with reflectors.
Dated this 22nd day of March 1898
I, CHARLES RALEIGH, of 58, Chancery Lane, in the County of Middlesex,
Mechanical Engineer, 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:-
My improvements relate to monogrammic sign-boards, capable of representing
any words, figures, or signs outlined by incandescent lamps or discs, same being
normally inoperative.
In construating

page_text: employ a series of "frames" corresponding with the maximum number of letters
or the like it is desired to represent at one and the same time, each "frame"
containing a monogrammic alphabetical design composed of lamp-holders of any
suitable construction, the terminals of which are directly connected with a
source of electricity. By inserting incandescing lamps in the lamp-holders in
the monogrammic design pertaining to the particular letter, numeral, or other
sign, it is desired to produce, each "frame" may be made to represent, in out-
line, such letter, numeral or other sign; the sign being inoperative until the
lamps are inserted. For daylight presentation, instead of lamps, suitably-
shaped and colored dises may be employed; disc-holders or clips taking the
place of the lamp-holders.
The discs may be of different colour to the background and may be constructed
of any suitable material, such as of mirror glass, cut or moulded glass, and they
may be illuminated by reflected light.
The incandescing lamps may be distinguished by partly painting or otherwise
marking them to render them more conspicuous when not illuminated, and the
lamps may be of different size, shape or colour, and be provided with reflectors.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I claim :-
1. In a monogrammic sign-board, a "frame" containing lamp-holders arranged
in a monogrammic alphabetical design, each lamp-holder being directly con-
nected with a source of electricity; the requisite letters or signs being delineated
by the insertion of lamps in the lamp-holders pertaining to that letter or sign.
2. In a monogrammic sign-board, a "frame" containing lamp- or disc-holders
arranged substantially as herein described and whereby the design is only ren-
dered operative by the insertion of the requisite lamps or discs for delineating
the letter or other sign to be represented.
3. A monogrammic inoperative sign-board, consisting of one or more "frames"
containing holders for lamps or discs constructed and operating substantially as
set forth.
