PROVISIONAL SPECIFICATION left by the said William Goodall at the
Office of the Commissioners of Patents on the 28th May 1881.
"
WILLIAM GOODALL, of Liverpool, in the County of Lancaster, Decorator.
IMPROVEMENTS IN CEILINGS, WALLS, PARTITIONS, AND
ARCHITECTURAL AND
DECORATIVE, MOULDINGS FOR DWELLING HOUSES AND OTHER STRUCTURES.”
"
The object of iny said Invention is to manufacture or produce ceilings, panels,
dados, pilasters, chimney picces, the surfaces of walls and partitions, architectural
mouldings, such as cornices, door heads and centre pieces, and decorative art
and plain work generally, where plaster or like compositions are used of a more.
highly finished character, and possessed of greater durability than has hitherto been
obtained.
For the above purposes, under the first part of my Invention, I make, cast, or
otherwise forin the following composition of inatter into the desired shapes. Plaster
of Paris, or Portland or other cement, sawdust, or wood pulp, glue or size, and
borax or equivalent salt. The said ingredients when mixed together are of about
the consistency of paste, and are in condition for pouring into moulds. Colouring
matter may be added if desired.
Under the second part, I cast the said composition when in a liquid condition,
into the desired shape or form round or between two or more layers of scrim or
canvas, wire netting, or other suitable strengthening or stiffening materials.
Under the third part, the architectural or decorative mouldings or other pieces.
when set are dried by artificial heat in a stove or otherwise, are soaked in glue or
size, and are again dried. After the second drying, the mouldings are ready for
the painter, gilder or polisher, and may be finished in the most elaborate manner
without fear of showing any of the effects resulting from damp or moisture.

WILLIAM GOODALL, of Liverpool, in the County of Lancaster, Decorator.
"IMPROVEMENTS IN CEILINGS, WALLS, PARTITIONS, AND ARCHITECTURAL
DECORATIVE MOULDINGS FOR DWELLING HOUSES AND OTHER STRUCTURES."
AND
The object of my said Invention is to manufacture or produce panelled and
plain ceilings, panels, dados, pilasters, chimney pieces, the surfaces of walls and
partitions, architectural mouldings, such as cornices, door heads, and centre pieces,
and decorative art and plain work generally where plaster or like compositions are
used of a more highly finished character, and possessed of greater durability than
has hitherto been obtained.
For the above purposes, under the first part of my Invention, I make, cast, or
otherwise form the following composition of matter into the desired shapes. Plaster
of Paris, or Portland or other cement, sawdust, wood pulp, glue or size and borax,
or an equivalent salt, as regards action and effects when mixed with the materials
above mentioned, for instance, alkaline borates may be used. The said ingredients
when mixed together are of about the consistency of paste, and are in condition for
pouring into moulds. Colouring matter may be added if desired. The proportions
of the materials will vary according to the quality of the work being produced, fine
work having more plaster or cement, and coarse work more sawdust or pulp. The
quantity of plaster or cement and glue or size should be such that the mixture
will set solid and hard. To anyone need to decorative plaster work, there will be
no difficulty in apportioning the ingredients according to the results desired.
Under the second part, cast or mould the said composition when in a liquid
condition into the desired shape or form around or between two or more layers of
scrim or canvas, wire netting, or other suitable strengthening and stiffening
materials. The moulds used are of the ordinary or any suitable construction, and
the casting is effected in the ordinary manner. The novelty of the composition
requiring no change in the usual proceedings for obtaining plaster casts.
Under the third part, the architectural or decorative mouldings or other pieces
when set are dried by artificial heat in a stove or otherwise, are soaked in glue or
size, and are again dried. It is advisable that the temperature during drying
should not be allowed to rise above 250° F. After the second drying the mouldings
are ready for the painter, gilder, or polisher, and may be finished in the most
elaborate manner, without fear of showing any of the effects resulting from damp
or moisture.
Having now described and particularized the nature of the said Invention in
such manner that others will be enabled to carry my improvements into effect, I
claim,―
First. The composition of matter under the first head, for the purposes set
forth.
Second. Casting or moulding the composition of matter under the first part,
substantially as set forth under the second part.
Third. Treating architectural mouldings or other composite parts of houses and
structures, substantially as set forth under the third part.
Fourth. Ceilings, walls, partitions, and architectural and decorative mouldings

page_text: for dwelling houses and other structures manufactured or produced, substantially
as herein set forth.
In witness whereof, I, the said William Goodall, have hereunto set my hand
and seal, this Eleventh day of November, in the year of our Lord One
thousand eight hundred and eighty one.
