PROVISIONAL SPECIFICATION.
Improvements in Show-cards, Signs, and other similar
Advertisements.
We, FREDERIC GRAINGER, of 71, Aireville Road, Frizinghall, near Bradford,
in the County of York, Manager, and GEORGE FREDERICK ASHLEY, of 20, Merton
Road, Bradford aforesaid, Designer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in show-cards, signs and other similar
advertisements, and its object is to obtain variegated or iridescent effects which
change as the beholder moves from one position to another.
For this purpose we employ a background consisting of two or more coloured
lines or stripes or black and white lines or stripes with or without additional
colours repeated side by side so as to more or less cover the ground. The back-
ground may be wholly or partly transparent when the light is transmitted from
behind.
At a suitable distance in front of this background, we place a grating consisting
of opaque lines or bars, preferably black or dark coloured, of any suitable
material. These bars or lines may be the same, or nearly the same pitch or
distance apart as the similar coloured lines or stripes of the back ground, and
parallel, or approximately parallel to them and they may be the same width or
slightly wider than the coloured lines or stripes. Or we may employ more
than one grating or the like, placed one in front of the other, each of which may
be of the same or different colours, and the bars or the like of the different
gratings may be parallel one to the other, or lie at an angle to each other.
We may use instead of the grating a sheet of glass or the like, having painted
or marked thereon black or dark coloured lines or bars, spaced in the same
manner. Or semi-fluted, or fluted glass may be used: i.e. glass with regularly.
spaced ribs, on one or both sides. This may be used without any particular
marking.
The device or subject matter of the advertisement may be put on the back-
ground by marking in a suitable or contrasting colour or colours or in black.
Or the device or advertisement may consist solely of the different coloured lines
or stripes on a background of any suitable material behind the grating or the
like.
Or a device may be affixed to the striped background, which device may be
either in white, black, gold silver or colour, or combinations of these: or it
may consist of differently coloured stripes of the same, or different width to
those of the background, which stripes may have more or less colours than the
background. Such device either with or without the stripes may have an edging
of white, black, gold, silver, or colour: and the device may be wholly or partly
raised or embossed above or recessed behind the face of the background.
Or again, certain stripes in the background may be stencilled out to the shape
of a device, or advertisement, and backed with coloured transparent paper, gela-

page_text: tine, or glass, coinciding with the parts stencilled out. Or the backing of the
background may consist of striped coloured transparent paper, gelatine or glass,
in two or more colours, of which each colour may be of the same width as the
stencilled spaces in the background. This transparent paper, gelatine or glass
may be mounted in a separate framework, which by suitable mechanical motion
causes the different colours to come successively opposite the spaces or stencilled
slits, thereby producing variegated colour effects. Or semi-fluted or fluted glass
of suitable thickness and pitch, or embossed glass of any pattern or design,
may be placed in front of the coloured striped transparent paper, gelatine, or
glass, and behind the background and in this case the background may be
stencilled out to the shape of the device or advertisement, irrespective of the
stripes in the background.
An effective result of the variegated and iridescent character is obtained by
the employment of a background bearing a reproduction of the colours of the
spectrum, arranged in their proper order in lines or stripes, and in employing
a grating of the same pitch, or nearly the same, as that of the repeating colours
of the background, and having bars the same, or nearly the same width as the
lines or stripes of the said colours.

Improvements in Show-cards, Signs, and other similar
Advertisements.
We, FREDERIC GRAINGER, of 71, Airville Road, Frizinghall, near Bradford,
in the County of York, Manager, and GEORGE FREDERICK ASHLEY, of 20, Merton
Road, Bradford aforesaid, Designer, 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:-
-
This invention relates to improvements in show-cards, signs and other similar
advertisements, and its object is to obtain variegated or iridescent effects which
change as the beholder moves from one position to another.
For this purpose we employ a background consisting of two or more coloured
lines or stripes or black and white lines or stripes with or without additional
colours repeated side by side so as to more or less cover the ground. The back-
ground may be wholly or partly transparent when the light is transmitted from
behind.
A suitable distance in front this background we place a grating consisting
of opaque lines or bars, preferably black or dark coloured, of any suitable
material. These bars or lines may be the same, or nearly the same pitch or
distance apart as the similar coloured lines or stripes of the back ground, and
parallel, or approximately parallel to them, and they may be the same width or
slightly wider than the coloured lines or stripes.
To fully describe our invention, reference is made to the accompanying sheet
of drawings, forming a part of this specification, in which similar figures of
reference indicate corresponding parts in each of the views.
Figure 1, is an elevation of a portion of the background of a show-card,
Figure 2, is an elevation of a portion of the grating.

page_text: Figure 3, is a sectional view showing the relative position of the background
and grate.
The background 2 is marked with coloured stripes of say three different
colours or shades 3, 4 and 5 repcated again and again and the lettering or
design 8 consists of stripes of the same pitch or width but of different colours
or the same combination of colours differently arranged. The bars of the
grating 10 may be the same distance apart as the stripes of the same colours are
apart.
It will be evident that the bars of the grating will more or less prevent one or
more of the coloured stripes from being seen and as the beholder moves his
position the stripes previously invisible will come into view and others be
hidden.
We may use instead of the grating a sheet of glass or the like, having painted
or marked thereon black or dark coloured lines or bars, spaced in the same
manner. Or semi-fluted or fluted glass may be used: i.e. glass with regularly
spaced ribs, on one or both sides. This may be used without any particular
marking.
The device or subject matter of the advertisement may be put on the back-
ground by marking in a suitable colour or combination of colours or in black.
Or the device or advertisement may consist solely of the different coloured lines
or strips on a background of any suitable material behind the grating or the
like. The device may be edged with a contrasting colour, white, black, gold
or silver.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination with a show-card or the like having a background con-
sisting of different coloured stripes, of a grating or the like in front, sub-
stantially as herein shown and described.
2. The combination with a show-card or the like having a background con-
sisting of different coloured stripes and bearing lettering or a device composed
more or less of different coloured stripes, of a grating or the like in front, sub-
stantially as herein shown and described.
