The Manufacture of New Compounds or Composition from Cork and
other Materials for Use as Substitutes for Wood, Leather, and
other Substances, or for other purposes to which same may be
applicable.
I, MAXIME HOCQUET of 15 Rue Brézin, Paris, in the Republic of France,
Retired Civil Servant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the production of the new composition or compounds
from cork and other material for use as substitutes for wood paper leather felt
ceramic ware and other substances or for any purposes for which it may be
applicable and has for its object to produce a composition or substance composed.
of cheap and easily procured elements which can be made capable of resisting
water, rigid or resilient or semi-flexible or otherwise, which will serve as a non-
conductor of heat or electrical insulator, and which, moreover can be turned in a
lathe carved or otherwise worked or moulded into shape, struck or stamped or
otherwise as desired.
Heretofore cork waste as is well known has been employed in the manufacture
of linoleum and in other ways, but my present invention is designed to employ cork
especially cork waste-for the production of a new compound by a new combina-
tion of elements therewith and a special process of treatment.
My present invention is as follows;-
The cork is first reduced to a granular pulverulent or other more or less fiuely,
divided condition according to the product required or I may simply employ waste
cork-dust already in condition for treatment according to my invention.
I then proceed in either of the two following ways:-
(1) To the cork as above I add a solution formed of gelatine, glycerine, tannin,
and bichromate of potash in suitable proportions, for instance this solution may
consist of the following proportions or thereabouts;-
Gelatine
Glycerine
Tannin
Bichromate of potash
60 parts.
8 parts.
18 parts.
14 parts.
To this mixture of cork and the above solution I.next add carbonate of lime
and resin in a dry state and in suitable proportions varying according to the
product desired and the whole is then submitted to heat and pressure both of which
latter are also regulated by the same considerations.
(2) Instead of proceeding as above, 1 may proceed as follows, viz. ;-
1 take the cork in the condition above described and first treat same by means of
a solution of borax and then dry same. When it is completely or sufficiently dry

page_text: in suitable proportions, for instance this solution or mixture may advantageously
consist of the following proportions ;-
Gelatine in sheets
Dutch glue
Glycerine
Crystallized sugar-
Ammonia
Flower of sulphur-
40 parts.
25 parts.
15 parts.
16 parts.
2 parts.
2 parts.
or thereabouts and these may advantageously be mixed and prepared in the
following or other suitable manner;-
In a vat or vessel of any suitable description (advantageously heated by any
suitable means such as a water jacket or steam jacket) I introduce gelatine in sheets
Dutch glue and glycerine. These substances are triturated or thoroughly mixed
under heat and thereafter when their temperature has been sufficiently lowered I
then add the mixture of powdered crystallized sugar and ammonia. The whole
mass is again vigorously stirred or mixed together and when ready (for instance on.
arriving at a state of ebullition) I add the flower of sulphur after which the.
whole mass is again stirred mixed or worked together in any suitable manner or
machinery for the purpose of obtaining perfect homogeneity or as near thereto as
possible.
These different elements may be employed in proportions varying (as previously
described) according to the results desired to be obtained and after having been
heated and mixed together in the aforesaid manner as above described the whole
mass is brought to a liquid or plastic condition by the addition of a suitable
quantity of tannin and bichromate of potash in solution. The tannin solution
may consist of one kilogramme of tannin to 10 litres of water and the bichromate
of potash solution about 1 kilogramme of bichromate of potash to 15 to 20 litres
of water the proportion of these two solutions being varied according to the
degree of 'hardness or otherwise which it is desired to impart to the product.
Thus the cork having been previously treated with the borax solution and then
dried and treated with this tanno-gelatinous-bichromate solution as above described
is then submitted to a suitable action such as vigorous agitation kneading or rolling
etc. with the object of forcing the added elements to enter the pores or interstices
of the cork.
When this is finished the mixture is dried and then reduced to powder and this
powder then put into moulds and compressed under heat or instead thereof this
composition may be otherwise moulded or formed into the articles or shapes or
forms desired in any other desired or suitable manner.
When moulding articles from this composition I may coat the exterior thereof in
any suitable manner (for instance by impregnating the surface at the time of
moulding) with any suitable powder such as metallic or mica powder mother-of-
pearl or other substances capable of being reduced to a powder and adapted to
give luminous or other effects to the made article.
It will thus be seen that carbonate of lime and dry resin can be dispensed with
if desired and other elements added in their places as above.

The Manufacture of New Compounds or Composition from Cork and
other Materials for Use as Substitutes for Wood, Leather, and
other Substances, or for other purposes to which same may be
applicable.
I, MAXIME HOCQUET of 15 Rue Brézin, Paris, in the Republic of France,
Retired Civil Servant, 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 :-
This invention relates to the production of the new composition or compounds
from cork and other material for use as substitutes for wood paper leather felt

My present invention is as follows:-
The cork is first reduced to a granular pulverulent or other more or less finely
divided condition according to the product required or I may simply employ waste
cork-dust already in condition for treatment according to my invention.
I then proceed in either of the two following ways:-
(1) To the cork as above I add a solution formed of gelatine, glycerine, tannin,
and bichromate of potash in suitable proportions, for instance this solution may
consist of the following proportions or thereabouts :-

I take the cork in the condition above described and first treat same by means of
a solution of borax and then dry same.. When it is completely or sufficiently
dry I then treat the mixture with a solution consisting of gelatine, Dutch glue
(French, Colle de Hollande) glycerine, crystallized sugar, ammonia, and flower of
sulphur, in suitable proportions, for instance this solution or mixture may
advantageously consist of the following proportions :-
Gelatine in sheets

heated and mixed together in the aforesaid manner as above described the whole
mass is brought to a liquid or plastic condition by the addition of a suitable
quantity of tannin and bichromate of potash in solution. The tannin solution may
consist of one kilogramme of tannin to 10 litres of water and the bichromate of
potash solution about 1 kilogramme of bichromate of potash to 15 to 20 litres of
water-the proportion of these two solutions being varied according to the degree
of hardness or otherwise which it is desired to impart to the product.
Thus the cork having been previously treated with the borax solution and then
dried and treated with this tanno-gelatinous-bichromate solution as above described
is then submitted to a suitable action such as a vigorous agitation kneading or
rolling etc. with the object of forcing the added elements to enter the pores or
interstices of the cork.
When this is finished the mixture is dried and then reduced to powder and this
powder then put into moulds and compressed under heat; or instead thereof this
composition may be otherwise moulded or formed into the articles or shapes or
forms desired in any other desired or suitable manner.
When moulding articles from this composition I may coat the exterior thereof
in any suitable manner (for instance by impregnating the surface at the time of

pearl or other substances capable of being reduced to a powder and adapted to
give luminous or other effects to the made article.
It will thus be seen that carbonate of lime and dry resin can be dispensed with
if desired and other elements added in their places as above.
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. The hereinbefore described process for the production of composition or
compound from cork and other materials which consists in mixing with cork-
reduced to a more or less finely divided condition-a solution formed of gelatine,
glycerine, tannin, and bichromate of potash and either with or without the addition
of carbonate of lime and resin in the proportions specified the whole is then
submitted to heat and pressure in the manner and for the purposes herein before
described.
2. The hereinbefore described process for the production of composition or
compound from cork and other materials which consists in treating cork-reduced
to a more or less finely divided condition-with a solution of borax and then
drying same and then mix with these a solution consisting of gelatine, Dutch glue
(French; "Colle de Hollande ") glycerine, crystallized sugar, ammonia and flower
of sulphur the various components being mixed and combined in the proportions
and in the manner specified and the composition thus obtained is moulded into the.
articles or forms desired or utilised in the manner and for the purposes hereinbefore
set forth.

page_text: 3. A new compound or composition obtained by the use of cork combined with
the other elements specified and treated by the processes hereinbefore described
substantially as and for the purposes set forth.
