Improvements in the Manufacture of Cement or Plaster Compounds.
I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and
in what manner the same is to be performed, as communicated to me by Franz
Schmeisser, of Mahlmamstrasse 9, Leipzig, Germany, Manufacturer, to be
particularly described and ascertained in and by the following statement :-
This invention relates to a cement or plaster compound which is specially adapted
for the restoration of existing mouldings or other pieces and is distinguished from
cements or plasters heretofore known by its superior hardness, and the advantageous
manner in which it can be used.
The cement or plaster compound which forms the subject of this invention is
made of gypsum pulp, cement pulp, or other plaster prepared by the admixture of
a suitable fast binding stuff, such as water, or glue or other similar compound, and
cocoa-nut fibres which are intermixed with the pulpy mass in such a way that the
resulting compound is intersected with the largest possible amount of such fibres.
A suitable proportion of the materials for producing the desired result, would in
nut fibres. If sand is added the proportion of cement or gypsum to the sand
ordinary cases be 50 kilos. of gypsum, cement or other plaster, and 5 kilos. of cocoa-
should be taken as 1 to 2.
As is well known cocoa-nut fibre will not absorb water, and therefore cannot rot,
swell or shrink. On the other hand the elasticity, toughness and consistency of
cocoa-nut fibre is exceedingly great.
The cocoa-nut fibre cement or plaster compound prepared as above described,
to which may be added any desired plaster or binding material, can be made into
the necessary shape of the article or part thereof and in this form can be secured
to the article or in position by pressure. The pressure should be so regulated as
to prevent the formation of air-spaces, and by such pressure the density of the
mass is increased to such an extent as to render it practically impossible to tear or
break the article or to break off its corners.
As the pressed mixture possesses great consistency to the point of being
practically indestructible, the substance is specially adapted for the restoration of
cement floorings, particularly gypsum floorings. In consequence of its light weight
and great consistency, the material is also adapted for the restoration of thin
cement plates of any size, particularly for roof coverings, and for all kinds of
objects used in building or ornamental architecture.
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;-
A cement or plaster compound consisting of a pulp prepared with fast-binding
stuff and intersected with the largest possible amount of cocoa-nut fibres
substantially as and for the purpose hereinbefore described.
