Improvements in the Preparation of Paint-olls.
I, JOHN BAPTISTA, of 26 South Third Street, Philadelphia, in the County of
Philadelphia, and State of Pennsylvania, United States of America, Inventor, do
hereby declare the nature of this invention to be as follows:-
:-
My invention relates particularly to an improved paint oil adapted to be used as
a substitute for ordinary linseed oil and my invention relates also to the process for
making the said oil.
The object of my invention is to utilize mineral oils for painting purposes some-
thing heretofore impracticable, and with this object in view, my invention consists
in the oil composed of linseed oil, mineral oil, suitable drying agents and also
coloring and clarifying agents, and my invention also consists in the process and
steps of the process hereinafter referred to.
This compound oil has been termed " Linosene" and in making the same,
mineral oils of suitable color, viscosity and volatility are mixed with definite
proportions of linseed which has been previously made into a drier by the agency
of the proper metallic oxides or otherwise. Definite amounts of resins whose
quality, etc., are regulated with reference to the density of the desired products,
are then dissolved in the mixture of mineral and linseed oils.
The resin usually employed is the American pine or hemlock rosin.
The details of the process are as follows:-
Finely broken rosin is first washed in naptha or benzine. Then miners neutral
oil or pressed oil of 350° fire test, more or less, with a specific gravity of 35° Beaume
more or less, and a cold test of 15° Beaume, more or less, is heated to a temperature
of 200° and while the oil is kept at this temperature, the finely broken and washed
rosin is thrown into the oil and dissolved said rosin being mixed with the oil in
the proportion of 26 pounds to each barrel (50 gallons) of the oil.
When the rosin has entirely melted, about one pound of pulverized shell lime is
stirred into each twenty-five barrels of the mixture which will have the effect of
bringing all sediment to the bottom.
To provide a drier for this oil, I use linseed oil boiled to 300° and borate of
manganese, the linseed oil being heated to 350° when the borate is added a little at
a time, about five pounds of the manganese to one barrel (50 gallons) of the oil, and
varnolette (which is a strong drier made from gum resin, lead, and manganese) is
then introduced into the mixture of linseed oil and borate of manganese in the pro-
portion of fifteen pounds of varnolette to one barrel of fifty gallons. This makes a
very strong drier.
This drier is then mixed with the mixture of mineral oil and
proportion of two gallons of drier to each barrel of resinated oil.
rosin, in the
After the mixture has settled, it is moved to a second tank where it is heated by
steam or otherwise and raised to a temperature of 150° more or less until the oil
clears.
After settling for a day, the compound is moved to the storage tank where three
barrels of raw linseed oil are mixed with each twenty barrels of the linosene com-
pound. The linseed has a quantity of sulphur, four pounds to each ten gallons of
linseed, which gives the linseed a red color, and when this mixture of linseed and
sulphur is poured into the linosene, it will produce the desired color to imitate
ordinary linseed oil.

I, JOHN BAPTISTA, of 26 South 3rd Street Philadelphia, in the County of
Philadelphia and State of Pennsylvania, United States of America, Inventor, 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 :-
My invention relates particularly to an improved paint oil adapted to be used as
a substitute for ordinary linseed oil, and my invention relates also to the process for
making the said oil.
The object of my invention is to utilize mineral oils for painting purposes some-
thing heretofore impracticable, and with this object in view, my invention consists
in the oil composed of linseed oil, mineral oil, suitable drying agents, and also
coloring and clarifying agents, and my invention consists further in the process and
steps of the process, hereinafter referred to and claimed.
This compound oil has been termed "Linosene" and in making the same,
mineral oils of suitable color, viscosity, and volatility, are mixed with definite
proportions of linseed which has been previously made into a drier by the agency
of the proper metallic oxides or otherwise. Definite amounts of resins whose
quality etc. are regulated with reference to the density of the desired products,
dissolved in the mixture of mineral and linseed oils.
The resin usually employed is the American pine or hemlock resin.
The details of the process are as follows: Finely broken rosin is first washed in
naptha or benzine. Then miners neutral oil or pressed oil of 350° F. fire test,
more or less, with a specific gravity of 35° Beaume more or less, and a cold test of
15° more or less is heated to a temperature of 200° F. and while the oil is kept at
this temperature, the finely broken and washed rosin is thrown into the oil and
dissolved said rosin being mixed with the oil in the proportion of 26 pounds to each
barrel (50 gallons) of the oil.
When the rosin has entirely melted, about one pound of pulverized shell lime is
stirred into each 25 barrels of the mixture, which will have the effect of bringing
all sediment to the bottom.
To provide a drier for this oil, I use linseed oil boiled to 300° F. and borate of
manganese, the linseed oil being heated to 350° F. when the borate is added a little
at a time, about five pounds of the manganese to one barrel (50 gallons) of the oil;
and varnolette (a drier made from melted rosin and lead and manganese) is then
introduced into the mixture of linseed oil and borate of manganese, in the pro-
portion of 15 pounds of varnolette to one barrel of fifty gallons. This makes a
very strong drier. This drier is then mixed with the mixture of mineral oil and
rosin in the proportion of two gallons of drier to each barrel of resinated oil.
After the mixture has settled it is moved to a second tank where it is heated by
steam or otherwise and raised to a temperature of 150° F. more or less until the oil
clears.
After settling for a day, the compound is moved to the storage tank where three
barrels of raw linseed oil are mixed with each 20 barrels of the linosene compound.
The linseed has a quantity of sulphur, four pounds to each ten gallons of linseed,
which gives the linseed a red color and when this mixture of linseed and sulphur is
poured into the linosene, it will produce the desired color to imitate ordinary
finseed oil.
An oil prepared as above described can be used as a substitute for linseed oil,
and with good effect thereby lessening the cost of paint compounds.

page_text: 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 herein described process of preparing paint oil, which consists in mixing
with mineral oil and a resinous compound, a mixture of linseed oil and suitable
drying agents, in the manner set forth.
2. The herein described process of preparing paint oil, which consists in melting
a resinous compound in mineral oil, and purifying the same, preparing a drier as
described of linseed oil, borate of manganese and varnolette, mixing the drier,
mineral oil and rosin, heating, clearing and coloring the mixture, in the manner set
forth.
3. An improved paint oil, composed of mineral oil and rosin, a drier composed of
linseed oil, borate of manganese and varnolette, and linseed oil and sulphur, all
combined in the proportions and for the purposes set forth.
