THOMAS ROBERT ABLETT of 36 Wemyss Road, Blackheath in the County of
Kent, Inspector of Art Teaching. I Thomas Robert Ablett do hereby declare the
nature of my said invention for "THE READY BRINGING INTO JUXTAPOSITION OF
.COLOURS, COLOURED MATERIALS OR SAMPLES "to be as follows:-
-
My invention consists of two or more concentric discs which revolve on a common
axle and have diameters of different lengths. The discs are arranged one above
another so that the smallest is uppermost & the largest at the bottom. This
arrangement leaves a certain space, near the circumference of each disc, exposed.
To the exposed surfaces are attached the colours, the coloured materials or the
samples. By revolving the discs the numerous colours, coloured materials or
samples may be brought, one after another, into juxtaposition with any others that
may have been selected, for the purpose, in the first place.
Two or more sets of Colour Wheels or Sample Wheels may be used in
combination..
or matching Samples.
I, THOMAS ROBERT ABLETT of 36 Wemyss Road, Blackheath, in the county of
Kent, Inspector of Art Teaching, do hereby declare the nature of my invention
for "THE READY BRINGING INTO JUXTAPOSITION OF COLOURS, COLOURED MATERIALS
OR SAMPLES," 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 of two or more revolving concentric discs, which revolve
all on one axle but have diameters of different lengths. The axle has a shoulder
to bear each disc, excepting the lowest.

page_text: The drawings show three discs of which Fig. 1 is the plan, Fig. 2 is the side
elevation & Fig. 3 is a section taken on the diameter A B of the plan. The discs
are arranged one over another so that the smallest in diameter is uppermost & the
largest at the bottom. (A plate is fastened in the underside of each disc, excepting
the lowest,) in order to separate the adjacent surfaces of the discs. The difference
in size leaves exposed a certain space (marked d), near the circumference of each
disc. To these exposed surfaces, which are bevelled, the colours, the coloured
materials or the samples are attached directly, as in the case of colours, or by one
of the usual means of attachment (by gumming, glueing, nailing or the like). By
revolving the discs, the numerous colours, coloured materials or samples, which are
attached to one disc, can be brought, one after another, into juxtaposition with any
of those on the other discs or with any others which are not on the discs but which
are held in the hand. When two or more colours, coloured materials or samples
are thus brought together they may be compared, tested or matched.
Two or more sets of discs, each set on its own axle, may be used in combination
in a way similar to that shown in Fig. 4 & in Fig. 5. (Each circle represents the
plan of a set of discs in Fig. 4 & Fig. 5). Each set of discs, which in use partly
covers another set, is provided with an extended axle.
"Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is'
1. The employment of discs, which revolve all on one axle, but have diameters
of different lengths, for comparing or testing colours & for comparing or matching
samples.
2. Bevelling the edges of the discs.
3. The attachment of plates (marked c) to the lower surface of the discs to
enable them to revolve freely one above another, especially whenever any coloured
material, or sample is fastened to the under side of a disc (marked E) as well as to
the upper side (marked d).
4. The axle with a shoulder to bear each disc (marked a).
5. The extended axle as dotted in Fig. 3 (marked D), which is to lift one set of
discs above another as that (marked E) & used in combination as in Fig. 5.
