PROVISIONAL SPECIFICATION.
A New Plastic Composition and the Process for Manufacturing the
same.
I, JOHN MENZIES, of 7, Tabernacle Street, Finsbury Square, in the City of
London, Metal Agent, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to manufacture a composition which can be used
for various useful purposes in the Arts and Manufactures, such as for the manu-
facture of power loom pickers and shuttles, for toys, statuettes, soles and heels of
boots and shoes, and for electrical insulating purposes.
The composition is made from equal parts of the solid residuum product derived
when distilling heavy petroleum, known as toluol, and another product also obtained
from petroleum being the last distillate passing out of the tar still as vapour
sometimes known as roofer's wax"; these constituents are dissolved by heat and
intimately mixed with each other. In place of the "roofer's wax" I may use an
equal quantity of para-rubber, gutta percha, or caoutchouc (preferably petroleum
caoutchouc). When in the heated liquid state I add shreds of leather, wool,
cotton, or other fibrous material, and petroleum carbon or plumbago.
As the mixture is very black aniline dyes or paints may be added at any suitable
stage of the process. These substances being mixed in a suitable vessel are while
warm put into moulds or dyes and pressed or formed into desired shapes, or are
rolled into sheets. For some purposes I use folds of cloth which have first been
thoroughly saturated in the mixture of toluol and roofer's wax," and are then
made up to the desired thickness.
The composition so produced is practically air and water tight, resists the action
of acids and alkalies and is impervious to ordinary atmospheric influences.

COMPLETE SPECIFICATION.
A New Plastic Composition and the Process for Manufacturing the
same.
I JOHN MENZIES of 7 Tabernacle Street, Finsbury Square, in the City of
London, Metal Agent, 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 this invention is to manufacture a composition which can be used
for various useful purposes in the Arts and Manufactures, such as for the manu-
facture of power loom pickers and shuttles, for toys, statuettes, soles and heels of
boots and shoes, and for electrical insulating purposes.
The composition is made from equal parts of the solid residuum bituminous
product derived when distilling heavy petroleum, and another product also obtained
from petroleum being the last distillate passing out of the tar still as vapour,
sometimes known as "roofer's wax"; these constituents are dissolved by heat and
intimately mixed with each other. In place of the "roofer's wax I may use an
equal quantity of para rubber, gutta percha, or caoutchouc. When in the heated
liquid state I add shreds of leather, wool, cotton, or other fibrous material for the

page_text: purpose of giving the requisite tenacity to the composition, and I also add carbon
or plumbago, or other heat resisting material.
As the mixture is very black, aniline dyes or paints may be added at any suitable
stage of the process. These substances being mixed in a suitable vessel, are while
warm, put into moulds or dies and pressed or formed into desired shapes, or are
rolled into sheets. For some purposes, I use folds of cloth which have first been
thoroughly saturated in the mixture of dissolved bituminous product and-" roofer's
wax," and are then made up to the desired thickness.
The composition so produced is practically air and water tight, resists the action
of acids and alkalies and is impervious to ordinary atmospheric influences.
For manufacturing a composition applicable for the soles and heels of boots and
shoes or for other uses where lightness of weight combined with strength or
wearing capacity are required, I use the following ingredients in about the propor-
tions stated

page_text: the ingredients as stated in Example A or B, a sheet or sheets of cloth or other
fabric, or wire or other gauze or netting. These sheets are immersed in the
dissolved bituminous product and "roofer's wax," when in a heated plastic
condition, and are then laid on the top and bottom or in the centre of the mass
before it is pressed or moulded. They thus form a backing or a hold for the
composition to cling to.
A composition suitable for application in the form of a paint is made of the
following ingredients in about the proportions stated.
This latter composition is dissolved in carbon bisulphide or other known suitable,
solvent, the consistence being regulated by the quantity of the solvent used. The
boracic acid is used for the purpose of giving the composition when dissolved,
the adhesive properties necessary for use in the form of a paint.
"
In manufacturing any of the compositions given in Examples A, B, C and D,
I proceed as follows:-The bituminous product (1) is first heated in a steani
jacketted or otherwise heated pan or vessel to about 200° F. When it is in a
plastic or viscous condition, the "roofer's wax (2) is added, and the mass is
constantly stirred until the ingredients are intimately mixed. The other
ingredients 3, 4, and 5, are then added, and the whole mass is then well stirred
about so that the ingredients are all well mixed together. The mass is then taken
out of the pan or vessel and while still in its heated or plastic condition is moulded,
pressed, or otherwise formed into blocks, slabs, sheets, or other desired forms or
shapes.
1:
In the Examples A, B, and C, the "roofer's wax may be omitted, and an equal
quantity of para rubber, gutta percha, or caoutchouc substituted.
"
It will be observed that the principal ingredients in my composition are the
bituminous product described and "roofer's wax (or its equivalents), the other
ingredients used being varied according to the purpose for which the composition
is required.
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 :-
1. A plastic composition manufactured from petroleum solid residium bituminous
product, and "roofer's wax," or its equivalents, with the addition of shreds of
leather, wool, cotton, or other fibrous materials, and of plumbago or mica, and
with or without the addition of carbon prepared substantially in the manner
hereinbefore described.
2. The use in the manner and for the purposes mentioned, of the solid
bituminous residium obtained in the distillation of petroleum, and roofer's
wax." or its equivalents, in about the proportions hereinbefore stated to which
other ingredients are added according to the nature of the product required, and
prepared substantially as described.
