Improvements in the Manufacture of Solid Elastic Oils suitable for
the Manufacture of Linoleum; Floorcloth; and similar Articles.
We, JAMES EDWARD BEDFORD, and CHARLES SAMUEL BEDFORD, both of 27, Kirk-
stall Road, Leeds in the County of York, Chemists, do hereby declare the nature
of this invention to be as follows:-
This invention has for its object the production of solid elastic oil products
from rosin oil or a mixture of rosin oil & linseed oil suitable for the manufacture
of linoleum floor cloth & similar articles which products by reason of the low
price of rosin oil are much more economical in use than if linseed oil alone were
used, compounded with colophony and Kauri gum in the ordinary manner.
Our invention can be carried out in two ways:—
'
First The rosin oil may be oxidised alone but with addition of suitable driers
in an apparatus such as is described in the Letters Patent granted to us
No. 7742/93 until by reason of the oxidation the rosin oil becomes converted into
a solid tenacious mass. This solid oxidised rosin oil may be used as a substitute
for colophony and Kauri gum to compound with the solid oxidised linseed oil by
fusion in a suitable steam heated pan or it may be added to linseed oil during
the boiling process in the preperation of corticine oil.
Second The mixture of rosin oil and linseed oil in various proportions may be
together oxidised along with driers in the aforesaid apparatus until a sample
when cold appears of a solid spongy consistency.
'
The charge is then transferred to an open steam heated pan provided with a
strong agitator wherein it is subjected to an increased heat & the kneading action
of the agitator which induces a reaction & further oxidation of the oil mixture.
When a cooled sample shows the charge has become strong elastic & free from
greasiness, the contents of the pan are discharged upon an iron or concrete floor
to cool.

page_text: of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention has for its object the production of solid elastic oil products
from rosin oil suitable for the manufacture of linoleum floorcloth and similar
articles which products by reason of the low price of rosin oil are much more
economical in use than if linseed oil alone were used, compounded with colophony
and Kauri gum in the ordinary manner.
Our invention can be carried out in two ways:—
First The rosin oil may be oxidised alone but with addition of suitable driers
in an apparatus such as is described in the Letters Patent granted to us
No. 7742/93 until by reason of the oxidation the rosin oil becomes converted into
a solid tenacious mass: For a charge of 10 cwts. rosin oil we add as drier 5 lbs.
borate or resinate of manganese and conduct the oxidation at a temperature of
115° Centigrade. This solid oxidised rosin oil may be used as a substitute for
colophony and Kauri gum te compound with the solid oxidised linseed oil by
fusion in a suitable steam heated pan or it may be added to linseed oil during
the boiling process in the preperation of corticine oil.
Second The mixture of rosin oil and linseed oil in various proportions may
be together oxidised along with driers in the aforesaid apparatus until a sample
when cold appears of a solid spongy consistency. The proportions we prefer to
employ are, linseed oil 6 cwts. rosin oil 4 cwts. with the following driers,
litharge 11 lbs. resinate of manganese 5½ lbs. The charge is then transferred to
an open steam heated pan provided with a strong agitator wherein it is subjected
to an increased heat from 120° to 140° C. and to the kneading action of the beaters
which induces a reaction and further oxidation of the oil mixture. When a
cooled sample shows the oil mixture has become strong elastic and free from
greasiness, the contents of the pan are discharged upon an iron or concrete floor
to cool.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is: :―
The preperation of solid elastic products from rosin oil or from a mixture of
rosin oil and linseed oil in the manner described.
