PROVISIONAL SPECIFICATION.
Improvements in Materials or Compounds to be used in the Manu-
facture of Moulded Articles, such as Door Handles, Insulators
for Electrical Purposes, Boxes, Toys, and other articles of the
like kind.
I, JAMES LANG, of Gunnersbury Villa, Gunnersbury, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My present invention relates to the manufacture of moulded articles formed of a
novel compound, the composition of which may be varied more or less, but con-
sisting principally of what is known as infusoria, combined with shale, asbestos,
whiting, resinous gums, oils, mastic and colouring matters, which when thoroughly
mixed and incorporated together in suitable proportions form a plastic mass which
when moulded into the desired form may be hardened under pressure and which
can be vulcanized in a vulcanizer in the ordinary well known way or hardened by
a much cheaper process by baking when in compressed moulds.
Such moulded articles are capable of being employed for various purposes. The
materials I employ are cheap and by using hand pressure and unskilled labour the
articles compare favourably as to cost with such articles as ordinarily made, such
for instance as door handles, finger plates, jewel boxes, puff boxes, pin trays, needle
cases, bon bon boxes, pipe cases, draughts, buttons, knife handles, blocks for
electric purposes, electric pushes and insulators, tool handles for surgical purposes,
cells for electrical accumulators or storage batteries, plaques for painting on,
frames for pictures, ornamental tiles, cut-offs, switches, ornamental roses for
furniture, toilet sets, brush and hand-glass backs, pomade pots, tobacco and snuff
boxes, bricks for model buildings or toys, and very many other such articles capable
of being moulded.

required.
The compounds described can be compressed in moulds and vulcanized under
various degrees of heat according to the elasticity, hardness, or tensile strength
that may be required.
I do not confine myself to the exact proportions of the materials used, and one
or more of the ingredients mentioned may be omitted and others substituted for
them as may be found desirable according to the purposes for which the compound
is to be used.
Ornamental metals or other suitable substances may be compressed into the
surface of the material during the process of moulding, for the purpose of pro-
ducing artistic effects in the articles when required.
The finished compound can be glazed on the surface by the process well known
in the manufacture of india rubber as hot pressing.

COMPLETE SPECIFICATION.
Improvements in Materials or Compounds to be used in the Manu-
facture of Moulded Articles, such as Door Handles, Insulators
for Electrical Purposes, Boxes, Toys, and other articles of the
like kind.
I, JAMES LANG, of Gunnersbury Villa, Gunnersbury, in the County of
Middlesex, Engineer, 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 :-
or
My present invention relates to the manufacture of moulded articles formed of a
novel compound, the composition of which may be varied more
or less, but
consisting principally, in most cases, of what is known as infusoria (infusorial earth
"fossil meal"), combined with shale, asbestos, whiting, resinous gums, oils,
mastic and colouring matters, which when thoroughly mixed and incorporated
together in suitable proportions form a plastic mass which when moulded into
the desired form may be hardened under pressure, and which can be vulcanized
in a vulcanizer in the ordinary well known way, or hardened by a much cheaper
process by baking when compressed in moulds.
Such moulded articles are capable of being employed for various purposes. The
materials I employ are cheap and by using hand pressure and unskilled labour the
articles compare favourably as to cost with such articles as ordinarily made, such
for instance as door handles, finger plates, jewel boxes, puff boxes, pin trays, needle
cases, bon-bon boxes, pipe cases, draughts, buttons, knife handles, blocks for
electrical purposes, electric pushes and insulators, tool handles for surgical
purposes, cells for electrical accumulators or storage batteries, plaques for painting
on, frames for pictures, ornamental tiles, cut-offs, switches, ornamental roses for
furniture, toilet sets, brush and hand glass backs, pomade pots, tobacco and snuff
boxes, bricks for model buildings or toys, and very many other such articles
capable of being moulded.
The compositions which I principally use are constituted as follows:-

page_text: I mix the materials which form the composition in heated pans, by means of
mixers or masticators or heated rollers of the kind ordinarily used in the manu-
facture of india rubber, or other suitable mechanism, and I then roll the compound
into sheets of such thickness as may be required.
The compounds described can be compressed in moulds and vulcanized under
various degrees of heat according to the elasticity, hardness, or tensile strength
that may be required.
I do not confine myself to the exact proportions of the materials used, and one
or more of the ingredients mentioned may be omitted and others substituted for
them as may be found desirable according to the purposes for which the compound
is to be used.
Ornamental metals or other suitable substances may be compressed into the
surface of the material during the process of moulding, for the purpose of pro-
ducing artistic effects in the articles when required.
The finished compound can be glazed on the surface by the process well known
in the manufacture of india rubber as hot pressing.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The materials or compounds for the manufacture of moulded articles such as
door handles, insulators for electrical purposes, boxes, toys, and other articles of
the like kind, consisting substantially of the materials herein described mixed,
moulded, and treated, in the manner and for the purposes described.
