Improvements in Oil for General Painting.
1, JOEL CLARKSON DECKER, of Laboratory, in the County of Washington,
and State of Pennsylvania, United States of America, Artist, 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 :—
The object of my invention is to produce a good composition oil possessing the
qualities of linseed oil for use as a vehicle for paint.
With this object in view 1 employ the composition set forth as follows; viz. :—
crude petroleum one gallon; yellow beeswax, one fourth to one half pound;
pulverized resin, one half pound; sulphate of zinc, one eighth to one fourth pound;
sugar (acetate) of lead, one eighth to one fourth pound; rubber one half to one
ounce; linseed oil,- one half to one pint.
The process of preparing the above composition is as follows :
I use what I please to term a steam still; similar to a large steam boiler provided
with a dome, a manhole through which the ingredients are introduced and having
the interior of the still provided with two sets of coiled tubing; one set being
perforated for purposes hereinafter described this still is provided at the dome
with the necessary steam connections and valves for controlling the steam and
vapors which may enter and again pass off from said still..
:
The crude petroleum is first introduced into the still through the manhole, or if
preferred a hopper may be used for this purpose. The oil is then blown by direct
steam which enters the still through the perforated coil. This operation is continued
for about six or eight hours or until the lighter properties (benzine and. naptha)
have passed out with the vapor or exhaust through a suitable condenser. This
condenser may consist of a coil of tubing passing through a tank or other receptacle
filled with cold water said condenser leading from the bottom of the said tank to
another tank partly filled with water, which separates the benzine and naptha.
The ingredients are dissolved separately by steam, suitable vessels being provided.
for this purpose. After all the ingredients are thoroughly dissolved I add the
sugar (acetate) of lead and sulphate of zinc to the petroleum. The steam is now
turned on through a closed or dry steam pipe and this solution of sugar (acetate) of
lead, sulphate of zinc and petroleum is boiled for about one hour, after which time
the steam is shut off. I next add the proportions of beeswax, pulverized resin
(adamanti gum) and rubber. Close the still and turn on steam again and boil for
about seven hours, more or less, to thoroughly amalgamate the ingredients. After
this operation has been concluded and the solution has been allowed to cool, the
proportion of linseed oil is added which completes the manufacture.
The oil is now tested as to gravity, using an oleometer glass for this purpose.
My oil at 35 gravity is excellent.
The above composite oil forms a good vehicle for painter's use in mixing their
various paints. It is non-volatile, inodorous, and has about the specific gravity of
the best linseed oil. It is also a good water-proof oil, and is possessed of excellent
antiseptic and preservative powers.
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. A paint vehicle or oil for painters use, composed of crude petroleum, yellow
beeswax, pulverized resin, sulphate of zinc, acetate of lead, rubber and linseed-oil
in substantially the proportions herein set forth.
2. The process of manufacturing a paint vehicle or oil for painters use, by

page_text: separating the lighter properties from the crude petroleum by the passage of direct
steam through said petroleum, dissolving the ingredients and adding them in the
proportions and boiling the admixture by steam indirectly, substantially as and for
the purpose specified.
3. In a paint vehicle or oil for painting use the ingredients set forth, combined
in substantially the proportions stated and the process of manufacture substantially
as and for the purpose specified.
