PROVISIONAL SPECIFICATION.
Improvements in Linoleum or Linoleum-like Compositions.
I, LOUIS KNOCHE, of Hamm, Westphalia, in the German Empire, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manufacture of linoleum and its principal objects
are to simplify and to reduce the cost of such manufacture.
In carrying this invention into effect ground or powdered cork is mixed with
oil of elaeococca vernicia (sometimes called aleurites cordata). The cork is placed
within the heated oil and is subjected to a certain temperature for a few hours.
The product may then be spread upon any desired fabric or material.
The following is a convenient example of how these improvements may be
carried out. Five hundred parts of oil of elaeococca are heated to 60° C. in a
tank or suitable receptacle provided with a stirring apparatus or agitator. Five
hundred parts of ground or powdered cork are then added gradually with constant
stirring until the cork and the oil are thoroughly mixed. The temperature is then
increased to 250° C. and this temperature is maintained for about two hours. By
this short treatment the mixture becomes so doughy that it may be shaped in
any desired manner or may be spread upon or combined with any desired fabric
or material. If desired, 'some resin or collodion may be added.

Improvements in Linoleum or Linoleum-like Compositions.
I, LOUIS KNOCHE, of Hamm, Westphalia, in the German Empire, 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 in and by the following
statement:-
-
This invention relates to the manufacture of linoleum and its chief objects
are to simplify and to reduce the cost of such manufacture.
It is well known that in the manufacture of ordinary linoleum, ground or
powdered cork is intimately mixed with linseed oil which has previously been
oxidised, the mixture is heated and then spread upon a suitable canvas or other
foundation. The oxidisation of the oil causes loss of time and necessitates the
employment of labour, both of which are avoided according to my present improve-
ments. Further, I avoid the final drying of the product and thus again reduce
the cost of production.

page_text: In carrying my present invention into effect, ground or powdered cork is mixed
with oil of elaeococca vernicia (sometimes also called aleurites cordata). The oil
is first heated, by preference, and the cork is then intimately mixed with it with
maintenance of heat during a sufficient time. The product may then be spread
upon any desired fabric or material or be moulded or otherwise formed as may
be required.
The following is a convenient method for carrying my improvements into
practical effect.
Five hundred parts of the oil of elaeococca are heated to about 60 deg. C., in a
tank or other suitable receptacle which is provided with a stirring apparatus or
agitator. Five hundred parts of ground or powdered cork are then gradually
added to the oil with constant stirring until the cork is thoroughly mixed with
the oil. The temperature is then increased to about 250 deg. C. and this tem-
perature is maintained for about two hours. By means of this short treatment
the mixture becomes so plastic or doughy that it may be shaped in any desired
manner or may be spread upon or combined with any desired and suitable material,
for example, upon a canvas foundation as in ordinary linoleum manufacture.
If desired there may be added to the mixture, other constituents such as resin,
collodion, castor oil and the like as is well understood in the manufacture of analo-
gous materials.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. The herein before described process for the manufacture of linoleum which
consists in mixing about equal parts of ground or powdered cork and oil of
elaeococca vernicia at a moderate temperature, then raising the temperature to
about 250 deg. C., cooling the product and finally spreading it upon a suitable
basis, moulding it to a required form or otherwise finishing it by known methods,
substantially as set forth."
2. As a new article of manufacture the linoleum-like product prepared with
ground or powdered cork and oil of elaeococca vernicia, substantially as hereinbefore
described.
