SAMUEL H. TITUS, OF ST. LOUIS, MISSOURI.

IMPROVED COATING FOR OIL BARRELS AND CASKS.

Specification forming part of Letters Patent No. 37,018, dated November 25, 1862.

To all whom it may concern:

Be it known that I, SAMUEL H. TITUS, of the city of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and useful Coating for the Inside of Vessels for Containing Petroleum-Oil; and I do hereby declare that the following is a full and exact description of my invention and the mode of compounding, preparing, and applying the same.

The nature of my invention consists in the preparation of a compound and its application to the interior surface of casks or containingvessels for petroleum-oil, coal-oil, and their products, which liquids are liable to permeate or soak through the wood of their ordinary containing-vessels. This coating is not dissolved nor penetrated by petroleum-oil nor by its vapor. By my invention the great expense of using metallic casks for holding such oilsis obviated, while the cost of preparing the ordinary wooden casks with my impervious coating for holding such oils is but trifling.

For the purpose I have named I first mix sulphuric acid with water in about the proportions of one ounce of acid to five gallons of water; then dissolve glue in the acidulated water in about the proportions of one pound of glue to five gallons of water. This solution, so compounded, when heated to as near the boiling-point asit can be used conveniently, is applied to the interior surface of the vessels by pouring in a bucketful (or any other sufficient quantity) and then moving the vessel so as to run the solution over every part of its interior, and then immediately pouring out all that does not penetrate or adhere to the surface of the cask. After having used a quantity of the solution for coating a cask, the portion that is poured out should be reheated before being applied to another cask. It may be applied to large open vessels with a brush. The acid causes the solution to be more fluid and to penetrate the surface of the wood-particularly hard, close-grained wood-better than a simple solution of gclatine. It also adds to the ordinary capability of the gelatine to re sist the absorbing action of the oils.

I would here state that I do not mean to con fine myself to the use of sulphuric acid, as any other acid, when used in proper proportions according to its strength, will subserve the same purpose. I have specified sulphuric acid for reasons of economy; but at the same time I intend to use any of the acids, in combination with the gelatine, for the purpose specified; and I would also state that I do not mean to confine myself to the exact proportions named of glue and water, as the proportion of glue used should vary with the quality of the glue and with the temperature at which it is applied. For reasons of economy, in proportion as the temperature of the cask or of the solution is lowered the proportion of glue should be less, so that too thick acoating may not adhere to the cask.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

The solution of gelatine, compounded substantially as specified, and its application to the interior of casks and other vessels, in the manner and for the purpose substantially as described.
