An Improved Construction of Letters or Signs for Advertising or
other Purposes.
I, SAMUEL ARTHUR MASON FARNWORTH of York Chambers Adelphi in the
County of London Agent do hereby declare the nature of this invention to be as
follows:-
This invention relates to the method of displaying advertisements or signs by
means of liquids contained in transparent vessels and the object of this invention is
to render such advertisements or signs more striking and attractive to the eye.
According to this invention I enclose in a suitable vessel or vessels (preferably
of colorless glass) a suitable liquid preferably distilled water to which may be
added suitable transparent coloring matter such as aniline colors or solutions of
chemical salts and hermetically seal the said vessel or vessels.
These vessels I arrange in a suitable frame or frames in such a manner as to
form letters words or devices which when displayed in a shop window or other
suitable situation with a light or lights behind them form a very striking advertise-
ment or sign.
I have found in practice that a glass tube or tubes blown into a series of
connected spheres and bent into the required shape are very effective the said
spheres forming lenses which when illuminated from behind or otherwise are very
attractive.
Instead of the glass tubes above mentioned I may use separate vessels of glass or
other suitable material either spherical lenticular or prismatic filled with a suitable
liquid so as to get the best effect arranged in a frame or frames to form letters
words or devices.
This forms a cheap and effective method of displaying advertisements or signs
and is particularly applicable to cases where the subject matter of the advertise-
ment requires to be frequently altered as for instance in theatrical advertisements.
Instead of using colorless vessels filled with a colored liquid I may use vessels of
colored glass or other suitable material filled with colorless liquid.

COMPLETE SPECIFICATION.
An Improved Construction of Letters or Signs for Advertising or
other Purposes.
I, SAMUEL ARTHUR MASON FARNWORTH of York Chambers Adelphi in the
County of London Agent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
ained in and by the following statement:
This invention relates to the method of displaying advertisements or signs by
neans of liquids contained in transparent vessels and the object of this invention is
o render such advertisements or signs more striking and attractive to the eye.
According to this invention I enclose in a suitable vessel or vessels (preferably
of colorless glass) a suitable fluid preferably distilled water to which may be added
suitable transparent coloring matter such as aniline colors or solutions of chemical
alts and hermetically seal the said vessel or vessels.

page_text: These vessels I arrange in a suitable frame or frames in such a manner as to
form letters words or devices which when displayed in a shop window or other
suitable situation with a light or lights behind them form a very striking advertise-
ment or sign.
I have found in practice that a glass tube or tubes blown into a series of
connected spheres and bent into the required shape are very effective the said
spheres forming lenses which when illuminated from behind or otherwise are very
attractive.
Instead of the glass tubes above mentioned I may use separate vessels of glass
or other suitable material either spherical lenticular or prismatic filled with a
suitable liquid so as to get the best effect arranged in a frame or frames to form
letters words or devices.
This forms a cheap and effective method of displaying advertisements or signs
and is particularly applicable to cases where the subject matter of the advertise-
ment requires to be frequently altered as for instance in theatrical advertisements.
Instead of using colorless vessels filled with a colored liquid I may use vessels of
colored glass or other suitable material filled with colorless liquid.
And in order that my said invention may be the better understood I will proceed
to explain the same with reference to the accompanying sheet of drawings in
which
Fig. 1 represents side view of an apparatus for displaying advertisements
constructed according to this invention.
Fig. 2 end view of same.
Figs. 3 4 and 5 are details hereinafter referred to.
The same letters denote the same parts in all the figures.
a is a frame composed of sheet iron zinc or any other suitable material perforated
with holes to admit the glass spheres bbbwhich are arranged to form words letters
or devices.
These spheres are made of colored or colorless glass filled with distilled water
acid alcohol or other suitable fluid which may be either colorless or colored by
means of aniline dyes solutions of chemical salts or other suitable transparent
coloring material. The spheres bare held in place by means of clips d attached to
the plate or frame a see Fig. 3 and the whole illuminated by the gas jets for by
other suitable means arranged preferably behind the frame or plate a the whole
forming a very striking and effective advertisement.
To prevent the fluid contained in the glass spheres bb from freezing in exposed
situations I fill the same with alcohol an acid or any other suitable liquid which
freezes only at excessively low temperatures.
This method of displaying advertisements is particularly applicable to cases in
which the subject matter of the advertisement requires to be frequently changed
for example theatrical advertisements. In such cases the letters might be cut out of
smail sheets as in Fig. 5 and arranged on a suitable frame.
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 what I
claim is
Constructing letters or signs for advertising or other purposes of hermetically
sealed spherical lenticular or prismatic transparent vessels filled with transparent
liquid and illuminated all substantially as set forth.
