Improvements in the Treatment of Refuse or other Cork to Form'a
Tenacious Composition suitable for Use for Structural and other
Useful and Ornamental Purposes.
I, FRANK BARTLEET, of Hudcar Hill, Freetown, Bury, in the County of Lancaster,
Cork Manufacturer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to the treatment of refuse (or other) cork in com-
bination with other materials for the production of an artificial composition
capable of being pressed or moulded into various forms, and suitable for use for
structural and a variety of other useful and ornamental purposes too numerous
to specify.
Some of the principal qualities proposed by this artificial composition when
manufactured and treated as hereinafter described are as follows:-viz: impervious-
ness to water and insolubility in that and other solvents, great tenacity strength
and durability, capability of resisting dry or moist heat, hot or cold water, oils,
acids or other fluids, also non-conductibility of heat, sound and electricity. It
is light flexible and almost indestructible to blows or hammering and will resist
the attacks of white ants and other destructive insects, and is capable of being
cut or sawn into sheets, turned, moulded, or otherwise wrought into any desired
shape it can be screwed, nailed, cemented or otherwise connected to itself or
other materials and will take a fine polish, and may be painted grained varnished
or otherwise treated so as to be used for all kinds of ornamental or decorative
purposes:

***
Some of the principal uses of the improved composition may be enumerated
as follows:-
For general building purposes, such as building and paving blocks tiles and
slabs, flooring planks, partitions decorative or plain panels, mouldings and the
like, carved work of all descriptions for walls ceilings and other parts of build-
ings. For ship building and general engineering purposes such for example as
the making of cold air chambers, constructing or lining refrigerators of all kinds,
and for use in all cases where a non-conductor of heat is required such as for
packing cases for the conveyance of perishable substances or dangerous explosives,
or other articles or substances, also as a non-conducting covering for boilers,
steam pipes, and the like, and as a packing for steam pistons valves bearings for
revolving shafts and so forth, and with my composition for these purposes I
may mix French chalk, plumbago, powdered antifriction metals or other sub-
stances or mixtures thereof with a view of reducing friction.
Also as a substitute for earthenware for the manufacture of all kinds of un-
breakable pans, mugs, and other vessels pipes and the like and for other purposes
to which earthenware is ordinarily applied.
And as a substitute generally for india-rubber, gutta percha, asbestos, leather,
and similar materials.

page_text: Its quality as an insulator for electricity also renders it very valuable as a
substitute for porcelain ebonite and other similar substances for all kinds of electric
constructive purposes.
Its strength, durability and lightness render it also applicable to the manu-
facture of all kinds of appliances for athletic purposes, such as Indian clubs,
dumb-bells, skittles cricket and golf balls and the like, as well as for all kinds
of toys which require to be made of a light and comparatively indestructible
material.
In fact the improved composition may be applied to almost an infinity of useful
and ornamental purposes wherein any or all of the qualities above mentioned
are desirable.
For the purpose. of my invention I take refuse or other cork in a granulated or
powdered form and mix with it intimately in suitable quantities any of the following
gum-resins or other like adhesive substances, viz: shellac, resin, copal, damar,
manila, sandarac, elemi, gutta percha, tar, pitch, cellulose or one of its com-
pounds and the like in the form of powder or dissolved in or mixed with a
sufficient quantity of methylated spirit, ether, or one of the alcohols, benzene, benzo-
lene, naphtha, carbon disulphide carbon tetrachloride, chloroform, furfurol or other
suitable solvent to convert it into a solution or plastic form. Any of these sub-
stances may be used by itself or in a combination of two or more of them, using
of course the necessary solvent, or one or more may be used in solution along
with one or more in a finely divided condition, or I may use a solution of oxide
of copper in ammonia or other mineral compound capable of cementing cork or
cellulose or mixtures of these with one or more of the above mentioned substances.
When these materials have been thoroughly mixed and worked together with
the powdered or granulated cork the resulting mass is spread out and allowed
to dry gradually when necessary until all or most of the solvent, has evaporated.
It is then rammed into suitable metal or other moulds according to the nature
size and form of the article to be made until a sufficient density has been obtained
after which it is submitted to hydraulic or other pressure to consolidate the same
to the required density. It is then placed in an oven and baked or heated in the
mould to a temperature between 200 and 300° Fahrenheit or thereabouts, and
afterwards allowed to cool when it can be removed from the mould, and if desired,
turned, cut, sawn, polished, or otherwise treated.

Improvements in the Treatment of Refuse or other Cork to Form a 4
Tenacious Composition suitable for Use for Structural and other
Useful and Ornamental Purposes.
I, FRANK BARTLEET, of Hudcar Hill, Freetown, Bury, in the County of Lancaster,
Cork Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained 4
in and by the following statement :-
―
This invention relates to the treatment of refuse (or other) cork in combination
with another material or materials for the production of an artificial composition
capable of being pressed or moulded into various forms, and suitable for use for

page_text: structural and a variety of other useful and ornamental purposes too numerous
to specify.
Some of the principal qualities proposed by this artificial composition when
manufactured and treated as hereinafter described are as follows:-viz: impervious-
ness to water and insolubility in that and other solvents, great tenacity, strength
and durability, capability of resisting dry or moist heat, hot or cold water, oils,
acids or other fluids, also non-conductibility of heat, sound and electricity. It
is light flexible and almost indestructible to blows or hammering and will resist
the attacks of white ants and other destructive insects, and is capable of being
cut or sawn into sheets, turned, moulded, or otherwise wrought into any desired
shape, it can be screwed, nailed, cemented or otherwise connected to itself or
other materials and will take a fine polish, and may be painted grained, varnished
or otherwise treated so as to be used for all kinds of ornamental or decorative
purposes.
Some of the principal uses of the improved composition may be enumerated
as follows:-
For general building purposes, such as building and paving blocks, tiles and
slabs, flooring planks, partitions decorative or plain panels, mouldings and the
like, carved work of all descriptions for walls ceilings and other parts of build-
ings. For ship building and general engineering purposes such for example as
the making of cold air chambers, constructing or lining refrigerators of all kinds,
and for use in all cases where a non-conductor of heat is required such as for
packing cases for the conveyance of perishable substances or dangerous explosives,
or other articles or substances, also as a non-conducting covering for boilers,
steam pipes, and the like, and as a packing for steam pistons valves bearings for
revolving shafts and so forth, and with my composition for these purposes I
may mix French chalk, plumbago, powdered antifriction metals or other sub-
stances or mixtures thereof with a view of reducing friction.
Also as a substitute for earthenware for the manufacture of all kinds of un-
breakable pans, mugs, and other vessels pipes and the like and for other purposes
to which earthenware is ordinarily applied.
And as a substitute generally for india-rubber, gutta percha, asbestos, leather
and similar materials.
Its quality as an insulator for electricity also renders it very valuable as a
substitute for porcelain ebonite and other similar substances for all kinds of electric
constructive purposes.
Its strength, durability and lightness render it also applicable to the manu-
facture of all kinds of appliances for athletic purposes, such as Indian clubs,
dumb-bells, skittle, cricket and golf balls and the like, as well as for all kinds
of toys which require to be made of a light and comparatively indestructible
material.
In fact the improved composition may be applied to almost an infinity of useful
and ornamental purposes wherein any or all of the qualities above mentioned
are desirable.
For the purpose of my invention I take refuse or other cork in a granulated or
powdered form and mix with it intimately in suitable quantities any of the following
gum-resins or other like adhesive substances, viz: shellac, resin, copal, damar,
manila, sandarac, elemi, gutta percha, tar, pitch, cellulose or one of its com-
pounds and the like in the form of powder or dissolved in or mixed with a
sufficient quantity of methylated spirit, ether, or one of the alcohols, benzene, benzo-
lene, naphtha, carbon disulphide carbon tetrachloride, chloroform, furfurol or, other
suitable solvent to convert it into a solution or plastic form. Any of these sub-
stances may be used by itself or in a combination of two or more of them, using
of course the necessary solvent, or one or more may be used in solution along
with one or more in a finely divided condition, or I may use a solution of oxide
of copper in ammonia or other mineral compound capable of cementing cork or
cellulose or mixtures of these with one or more of the above mentioned substances.

page_text: For example I find that for most purposes a simple, and convenient way of
making the improved composition is to mix the granulated cork with; the well
known aqueous solution of shellac with borax as follows:-
For each hundred weight of granulated cork dissolve about two pounds and
three quarters of shellac with three quarters of a pound of borax and three and
a half gallons of water.

When these materials have been thoroughly mixed and worked together with
the powdered or granulated cork the resulting mass is spread out and allowed
to dry gradually when necessary until all or most of the solvent has evaporated.
It is then rammed into suitable metal or other moulds according to the nature
size and form of the article to be made until a sufficient density has been obtained
after which it is submitted to hydraulic or other pressure to consolidate the same
to the required density. It is then placed in an oven and baked or heated in the
mould to a temperature between 200 and 300° Fahrenheit or thereabouts and
afterwards allowed to cool when it can be removed from the mould, and if desired,
turned, cut, sawn, polished, or otherwise treated.
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:-
1. The treatment of refuse or other cork in a granulated or powdered form
by the addition thereto of gums resins or other like adhesive substances herein
mentioned capable of cementing together cork or cellulose or mixtures of these
with one or more of the other above mentioned substances, either in a powdered
form or dissolved by means of a suitable solvent..
2. I claim the formation of a tenacious composition suitable for structural and
other useful and ornamental purposes by mixing, kneading and working together
powdered or granulated cork with one or any two or more of the gum resins or
ingredients herein before referred to, and spreading out the resulting mass and
allowing the same to dry gradually until all or most of the solvent has evaporated,
then ramming such composition into suitable metal or other moulds and sub-
mitting it to hydraulic or other pressure and afterwards baking or heating the
same whilst in the mould substantially as herein before described.
