l TES GERALD EDWIN HUGHES, SR, OF KANSAS CITY, MISSOURI.

PROCESS FOR TREATING OILS.

No Drawing.

To all whom it may concern:

Be it known that I, GERALD EDWIN HUGHES, Sn, a citizenot the nited States, and a resident of the city of Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in a Process for Treating Oils; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to a process and the product formed by treating linseed oil or other oils to produce a more valuable and durable product for use in paint and varnish making.

Hitherto the tanked or raw linseed oil has always been laboriously refined and treated to produce a liquid drier or japan which treatment necessitated complex apparatus and the lapse of much time to obtain a good product.

It is an object of the invention to provide a method for the production of a very powerful drier and one which gives a much more durable paintv It is also an obj vide a method of producing a linseed or other suitable oil paint constituent in amucli shorter time and in a more positive manner.

It is a further object of the invention to provide a cheaper oil for paint making and one which functions in a manner equal if not superior to the best grades of linseed oil now on the market.

Otherand further objects of this invention will appear from the disclosures in the specification.

The invention (in a preferred form) is hereinafter more fully described.

-'lhe process is as follows:

The linseed or other oil, is put into standard copper kettles, preferably in 100 gallon lots, though larger or smaller quantities may be treated if desired. For each 100 gallons of oil there is provided approxim tely 100 pounds of ghii'e, either bone or not glue consisting preferably of one lump contained in a wire basket about 18"X36".

The oil and glue are then gradually heated over a uniform fire, which is kept carefully regulated. The glue originally floats on the surface of the oil but after some heating it settles to the bottom of the containing basket. In about an hour the glue begins to expand, and soon attains a spongy consistency. As soon as this expansion'occurs, the lump Application filed February 14, 1921.

ect of this invention to pro Serial No. 444,935.

The mass of the glue is not incorporated" into the oil, as the surface of the lump hardens and forms a crust, through which the oil permeates and only certain parts or molecules of the glue go into solution.

After a time action ceases and the surface of the oil-becon1es quiescent. The baskets containing the lumps of glue are then lit'tcd out of the oil and the oil is subjected to further heat for approximately eight hours at a slow steady rate which. however, is never allowed to rise to the boiling point of the oil.

There is hereby produced an oil which has been tested and found superior in every re spect to any pure linseed oil or any oil on the market, and forms a dry hard varnish having exceptionally durable and lasting qualities. Samples of paint and varnish have been made with this oil and applied to cement, iron, plaster walls, and the like, and exposed to all conditions of use, weather, etc., with remarkable results. The residue of glue remaining in the baskets is placed in troughs and covered half over with water, the action of the water being to soften the glue to a jelly for a second treatment. In the original treatment the glue absorbs much of the oil and gains about 100% in weight, besides acquiring a solid rock-like consistcncy. llowever, in about a weeks time the water has materially softened the lumps of oily glue which are then put into double boilers and heated until all the water is extracted. To the residue is added kerosene, or coal oil, in the proportion of .one gallon of kerosene to one pound of jelly, and this is heated gently for about six hours with practically a duplication of the original method. and this second run of oil is usually added to the first in approximately the proportions of one-third to two-thirds of the latter. This results in a particularly good product, tested and found to be superior to any oils now on the market.

Another method which yields similar results consists in treating "100 gallons of kerosene or coal oil with 100 pounds of glue in the same manner as originally outlined above in the case of linseed oil. This treated kerosene is then mixed with either raw or treated linseed oil in equal parts, say 100 gallons of kerosene, with 100 gallons of linseed oil.

After these treatments as described a rcsiduestill remains ofthe original .glue. This residue is mixed with litharge and rosin in approximately equal proportions and gradually heated, the resin melts first.

' and a slight polymerization may also take which place. These partly saponified glycerides are particularly good oxygen absorbers, which, whenthe oil is spread out in thin films. are converted into an elastic mass forms a durable and lasting varnish.

The oil as produced by this process may be mixed with inferior and cheaper oils and still function as well as the highest grade hoiled linseed oil now on the market, thus ell'ecling a considerable saving.

I am aware that numerous details of the process may be varied through a'wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patentgranted otherwise than necessitated by the prior art.

l claim as my invention:

1. A method of treating oils including heating a vegetable oil of the drying type with a quantity of glue.

2. A method of treating vegetable oils of the drying type including heating the oil with a quantity of glue in the proportions of one pound of glue to one gallon of oil.

A method of treating oils including hcatinglinseed oil with a quantity of glue.

4. A method of treating oils including heating linseed 011' with a quantity of glue 1 in the proportions of one pound of glue to one gallon of oil until chemical action ceases.

5. A method of treating vegetable oils of the drying type including heating the oil with a quantity of glue until chemical action ceases, then removing the glue and subjecting the oil to a slow heat for approximately eight hours.

6. The method of treating linseed oil which includes heating oil and glue together 'in the proportions of one gallon of oil to one pound of glue until the glue swells, then suspending the glue in the heated oil in such a manner that one third of its volume is submerged, continuing to heat until action ceases, removing the glue and finally heating the oil for eight additional hours.

7. A method of making paints and varnishes including heating linseed oil with a quantity of glue until chemical action ceases, removing the glue,soaking the same in water to soften it, and heating the resultant jelly with kerosene.

8. A method of making paints and varnishes including heating linseed oil with a quantity i of glue until chemical action ceases, removing the glue, soaking the same in water to soften it, and heating the re sultant jelly with kerosene, then maxing the treated linseed oil with the treated kerosene.

9. A method of making paints and vlar- .nishes including heating linseed oil with glue, in the proportions of one gallon of oil to one pound of glue, until action ceases, re-

moving the glue, soaking the same in water to soften it, and heating the resultant jelly .wit'hkerosene in the proportions of one pound of the jelly to one gallon of kerosene,

. then mixing the treated linseed oilwith the treated kerosene. I

10. An oil for paints including linseed oil and kerosene treated with glue.

11. Anoil for paints including linseed oil treated with glue. i

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
