PROVISIONAL SPECIFICATION.
A New or Improved Method of or Process for Manufacturing Sheets,
Plates, Blocks, and other Objects from Cork Wood Waste.
1, CARL EDUARD MEYER, of Bremen, Germany, Merchant, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a new or improved method of or process for manu-
facturing sheets, plates, blocks or other objects from cork wood waste. Owing to
the nature of cork wood and the objects usually manufactured therefrom there is
essentially a large percentage of waste. Hitherto this waste has mainly been
usable in the manufacture of cork floor-cloths but the supply largely exceeds the
demand, and the object of this invention is to enable cork waste to be utilized in
the manufacture of higher class goods and as a substitute for cork.
For this purpose the cork wood waste is reduced to small pieces or to a powder
and is placed in a dry state in a suitable vessel. An emulsion solution or extract
of casein or lactarene or other substance having similar properties is mixed there-
with and to which is added a small proportion of lime and water or other suitable
substance. The whole mass is then thoroughly incorporated and may be mechanically
treated by a press or pressure rollers. And by means of suitable pressure any:
desired shape may be imparted to the mass whilst in a plastic state before it is
dried or set.
The ultimate product resembles natural cork in many respects but it is more
impervious to water and may be used for many of the purposes for which natural
cork is used or where an elastic, light and uniform material is required. It may be
readily moulded to any required form and is not limited like natural cork to the
size of the growth.
Solutions of resin, glue or caoutchouc may be used instead of or in combination
with the casein or lactarene but the product is harder and loses much of its
elasticity.

COMPLETE SPECIFICATION.
A New or Improved Method of or Process for Manufacturing Sheets,
Plates, Blocks, and other Objects form Cork Wood Waste.
I, CARL EDUARD MEYER, of Bremen, Germany, Merchant, 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 a new or improved method of or process for manu-
facturing sheets, plates, blocks or other objects from cork wood waste.
Owing to the nature of cork wood and the objects usually manufactured there-
from there is essentially a large percentage of waste. Hitherto this waste has
mainly been usable in the manufacture of cork floor-cloths but the supply largely
exceeds the demand so that the larger portion of cork wood waste, inferior cork
wood, used corks and cætera may be considered as waste material and the object of
this invention is to enable cork waste to be utilized for various other purposes in
the manufacture of higher class goods and as a substitute for cork.
For this purpose the cork wood waste is reduced to small pieces or to a granular
form and is placed in a dry state in any suitable mixing vessel. Au emulsion

similar binding properties is mixed therewith and to this is added a small proportion
of lime and water. The whole mass is then thoroughly incorporated and whilst in
a plastic state it may be rolled into sheets or pressed into any required form, which
form is maintained after setting or, drying. A fairly heavy. pressure is advisable
and the rollers or press should be heated to say 100 degrees centigrade.
The ultimate product resembles natural cork in many respects but it is more
impervious to water and may be used for many of the purposes for which natural
cork is used or where an elastic, light and uniform material is required. It may be
moulded to any required form and is not limited like natural cork to the size of the
growth. It is also a better non-conductor of heat than the cork blocks made from used
corks or old cork stoppers and besides being slow of combustion carbonizes without
crumbling.
Solutions of resin, glue or caoutchouc may be used in the same manner as the
casein or lactarene but the product is harder and loses much of its elasticity.
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:
The application of cork wood waste for manufacturing compact masses by
impregnating reduced or granular cork wood with casein, lactarene or other
similar albuminous substance, or with a solution of resin, glue or caoutchouc,
whereupon by the combined action of pressure and heat any desired form may be
given to the mass, substantially as herein set forth.
