PROVISIONAL SPECIFICATION.
Improvements in Color Cakes, Blocks, or Sticks for Marking or
Coloring Purposes.
I, JAMES RICHARDSON CARRUTHERS, of 70 King Street, Tradeston, Glasgow,
in the County of Lanark, North Britain, Manufacturing Chemist, do hereby declare
the nature of this invention to be as follows, that is to say :-
My said invention relates to colored materials such as are employed for marking
sheep or other animals or for marking or coloring timber or other materials, articles,
or surfaces in a speedy manner and in many cases for temporary purposes.
The
object of my improvements is to render such coloring materials less liable to waste
or damage or to mark where not wanted, and more convenient and cleanly to use
and carry about or handle.
My invention consists in taking such materials in the form of cakes, blocks, or
sticks of any form suitable for making marks of the desired size and kind, and
covering such cakes, blocks, or sticks with a suitable coating composition which
for use is cut away or removed to expose a part of the color for marking. Amongst
the colored substances to be treated in this way are, blue keel, red keel, ruddle,
ochre, chromes, plumbago, and earth-like materials, colored with any suitable
colors, and which are of a suitable soft or friable nature and will mark easily. The
coating substance employed may be cement or other substance which is preferably
such as not itself to mark things which may touch it. The improved color cakes,
blocks, or sticks are better suited for being packed and conveyed from place to
place, than the materials as ordinarily prepared.
Dated this Twenty-fourth day of March 1892.

Improvements in Color Cakes, Blocks, or Sticks for Marking or
Coloring Purposes.
1, JAMES RICHARDSON CARRUTHERS, of 70, King Street, Tradeston, Glasgow,
in the County of Lanark, North Britain, Manufacturing Chemist, 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,
that is to say :-
My said invention relates to colored materials or "colors" such as are employed
for marking sheep or other animals, or for marking or coloring timber, metal, wool,
bales, or other materials, articles, or surfaces in a speedy manner, and in many cases,
it may be, for temporary purposes. The object of my invention is to render such
coloring materials less liable to waste or damage, from abrasion in handling, packing,
or transit, or to mark where not wanted, and more convenient and cleanly to use
and carry about or handle.
My invention consists in taking such materials in the form of cakes, blocks, or
sticks, of any form suitable for making marks of the desired size and kind, and
covering such cakes, blocks, or sticks with a suitable coating composition, which
for use is cut away or removed to expose a part of the color for marking. Amongst
the colored substances to be treated in this way are blue keel, red keel, ruddle,
ochre, chromes, ores, plumbago, and other earth-like materials, which may in some
cases be colored with any suitable colors, and which are of a suitable soft or friable

page_text: nature and will mark easily. The coating substance, which may be applied by
dipping, brushing on or in any other convenient way, may be any suitable cementi-
tious, coagulable, gummy, waxy, setting substance; or it may be adherent fibrous
pulp, or pitch or other resinous substance; being by preference such as not itself
to mark things which may touch it, although it may be colored to show the color
of the marking material which it covers. In some cases a coating or external
surface which will not mark to any objectionable extent may be formed on a color
cake, block, or stick, by simply hardening the outer surface by the application of
heat, with or without first moistening such surface with a suitable liquid.
The improved color cakes, blocks, or sticks, are better suited for being packed
and conveyed from place to place, and are more cleanly to handle, than the
materials as ordinarily prepared.
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 :
The preparing of color cakes, blocks, or sticks, for marking or coloring purposes
by coating the same substantially as and for the purposes hereinbefore described.
