Improved Composition or Use in the manufacture of Embossed
or Raised Designs on Panels and for other Uses.
I WALTER JOHN MICHELS of No. 9 Apsley Villas Twickenham in the County of
Middlesex, Gentleman do hereby declare the nature of this invention to be as
follows
--
The object of the invention is the production of a composition adapted for use
in the making of sign boards embossed signs or other raised devices, panels for
furniture decoration, or ornamental, decorative, architectural or other uses where
raised designs are desired to be produced in a material having rigidity, impermeability
to liquids or moisture and substantially unaffected by ordinary extremes of tempera-
ture; not liable to chip, fracture or crack.
For this purpose I employ a mixture of Cowrie or New Zealand Gum, ordinary
pine resin, paraffin wax, and ordinary commercial boiled linseed oil.
The materials in proper proportions are combined in a steam heated vessel provided
with stirrers or means for agitating the matters during heating.
In place of linseed oil, or in mixture therewith I sometimes use cotton seed oil; or
in substitution or combination therewith in like manner castor oil may be employed.
This mixing under heat is continued for say, about two hours or until by a test
quantity being withdrawn or judgment of the operation the admixture of the matters
is completed.
The proportions, for what for distinction I will call the principal composition, I
have found to give satisfactory results are:
Cowrie Gum
-
-
150 lbs.

page_text: This "filling' or additional composition may be added to the foregoing material
in proportion that will largely vary according to the character of the work and
texture desired.
This filling may consist of ground cork, wood pulp or fibre, whiting, agalite, (a
substance largely found in the State of Maine, United States, and there used in paper
making and the like) or other similar material.
Or such filling may consist of wood pulp or like finely reduced matter mixed with
Oxidized Oil Cement such as used by Floor Cloth Manufacturers or Vulcanised Oil
such as employed in Rubber manufactures and a proportion of the whole which gives
satisfactory results consists of

I WALTER JOHN MICHELS of No. 9 Apsley Villas Twickenham in the County of
Middlesex, Gentleman, 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 :-
The object of the invention is the production of a composition adapted for use
in the making of advertisements, sign boards, embossed signs or other raised
devices, panels, plaques, mouldings for furniture decoration, or ornamental, decorative,
architectural or other uses where raised designs are desired to be produced in a
material having rigidity, impermeability to liquids or moisture and substantially
unaffected by ordinary extremes of temperature; not liable to chip, fracture, or
crack.
For this purpose I employ a mixture of Cowrie or New Zealand Gum, ordinary
pine resin, paraffin wax, and ordinary commercial boiled or prepared linseed or
other vegetable oil.
The materials in proper proportions are combined in a steam heated vessel
provided with stirrers or means for agitating the matters during heating.
In place of linseed oil, or in mixture therewith I sometimes use cotton seed
oil; or in substitution or admixture therewith in like manner castor oil or admixtures
of all three oils or like oils of vegetable nature may be employed.
This mixing of the constituent materials for the principal composition under heat
in say a steam heated pan is continued for say, about two to three hours or
until by a test quantity being withdrawn or by the judgment and experience of
the operator the admixture of the matters is found to be completed.
The proportions for what for distinction I call the principal composition I have
found to give satisfactory results are.

page_text: This "filling" or additional composition may be added to the foregoing material
in proportion that will largely vary according to the character of the work and texture
desired.
This filling may consist of ground cork, wood pulp or fibre, whiting, flock, agalite,
(a substance largely found in the State of Maine, United States, and there used in
paper making and the like) or other similar material. On account of lightness I
prefer the wood pulp.
Mixed with such filling matter may be Oxidised oil Cement such as used by Floor
Cloth Manufacturers or Vulcanized Oil such as employed in Rubber Manufactures
and a proportion of the whole which gives satisfactory results consists of,
These materials may be mixed either in a radial mixer or by rolls or otherwise.
The above proportions will give a satisfactory result but they may be somewhat
varied according to the result required, whether, for instance, a greater or less degree
of density is desired or whether weight is a point of importance.
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 :-
The herein described plastic composition of matters for use in the manufacture of
embossed or raised designs on panels or slabs and for other uses requiring a hard
resultant material as set forth.
