Specification of Letters Patent.

Application filed May 7, 1910. Serial No. 559,867.

Patented May 30, 1911.

, My invention consists in the combination ciently free from water as to be soluble in of an oil or similar vehicle, an emulsifying agent such as a' Water-soluble soap suffithe oil and an oil-soluble compound of copper or other metal, having a substantial scale removing and lnsecticidal action.

As a basis for a, miscible oil, I prefer to use such oil bases as kerosene, hea or light petroleum oils, residual or asp alt oils, crude oils, rosin oils and spirits, or vegetable oils such as corn and cotton seed with their foots, residues and distillates, fish, menhaden, porgy, cod and other fish oils or animal oils such as lard, tallow and horse oils,

tankag'e grease, wool grease and degras ref- I use oils extracted from leather, etc., and solvent resins such as the resin obtained from guayule rubber and other resinous bodies.

As a 'basis for the saponifiable'qpody, I may use ordinary rosin and similar resins, 'oleic and stearic acid, 'sulfonated oil, wool grease, fish oils as menhaden oil or other saponifiable stock, but preferably I make use of ordinary rosin or a mixture of rosin and red oil or commercial oleio acid.

'ably use cresy If it becomes desirable to use a blending material of a henolic character, I preferiic acid for this purpose although creosote obtained from coal tar or other tar, and similar carbolic material may be employed. The metal base used as the insecticidal body in the form of a metalloorganic compound is preferably co per, lead, zinc, antimon or arsenic. As a asis for the soap, I pre er to make use of potash as the saponifymg alkali althou h soda or other alkaline agent may be us in whole or in part. The potash soaps, particularly those of rosin and oleic acid, 1f largel freed from water, are readil soluble un er the action of heat in most 0 the oils above mentioned. This is especially the case if creosoteor-similar-bleinding agent is present.

With kerosene-and the heavy petroleum oils,

some difficulty obtains in the dissolution in oil of these concentrated water-soluble soaps unless a little creosote or cresylic acid is present and 'for that reason, I prefer to use a blending agent of the character described,

In order to produce miscibility, that is to say, to make the oil capable of either dis solving in water to form a clear transparent solution or to form one which readily emuL. sifies with water and may be diluted indefi nitely without any material separation of I the emulsified particles, a substantial proortion of such water-soluble bodies must e carried by the oil.

The metallo-organio compound of a waterinsoluble character preferably is secured by making soap from among the metals mom tioned, as for example, copper soap may be made by precipitating sodlum oleate'with copper sulfate, of by heating copper carbon ate or hydroxid with red oil or oleic acid i to a temperature of about 200 C. for an hour or more metallo-organic oil-soluble compounds are produced. For example, two parts of red oil one part of guayule resin and one part of nel powdered carbonate of copper are heate to a temperature of 140 to 180 C. with the result that the carbonate dissolves to a very large extent forming a copper soap containing copper oleate and copper guayulate or some corn.- bination of copper with guayule resin. This metallo-organlc compound of copper, dlssolves very readily in oils and should be added to the oil basis used in makin the miscible oil. Preferably, the metal o-organic compound as specified is made and this is introduced. with rosin and ole1c aold into a kettle. Heat is applied and the mmture melted. Kerosene, heavy petroleum or other oil preferably-together with some,

when it'forms an emulsion of an exceednicely pm.

ingly-permanent character. Bly

portioning the amounts of oi and copper soap, a mixture may bemade, the 011 portion of which has theprecise speclfic gravity of water or of dilute soap so utionso that the emulsified particles W111 remain'msug Period after. thins-y pension for an indefinite tion to working strength.

A specific formula herein given by the way of illustration is as follows :20 pounds each of rosin and red oil are melted in a kettle and to this is added 50 pounds each of guayule resin, cresylic acid and kerosene oil. 80 pounds of copper oleate and guayulate base above mentioned are introduced and then approximately 13 pounds of a solution of caustic potash, of a specific gravity of 1.47 are added and the mixture heated and stirred until the incorporation is complete. A greenish colored mixture is thus produced which when mixed with a large amount of water forms a relatively permanent bluish green emulsion. As the copper is actually dissolved in the oil particles of the emulsion, there is not the danger in its' application that obtains with Bordeaux mixture and the like. For example, when the emulsion is sprayed on fruit trees, the copper does not act in a corrosive manner and cause defoliation.

Variations of the above illustrative for mula may be made in accordance with the character of the mixture desired for any particular application, as .for example, the guayule resin and cresylic acid may be substituted by rosin oil and petroleum oil or the proportions varied in other ways. The amount of copper compound or. other metallic base to be added depends on the strength required and the degree of emulsification.

For sprays, the'cresylic acid may be omitted entirely when the metallic base is readily soluble in the oil base used.

It will be noted that the formulas above set forth include a very substantial pei'centage of soap, as well as the oilsoluble copper compound itself, which imparts tothe comof copper sulfate, which would not. prop erly attain the object of the present invention, namely the roduction of an oil of satisfactory miscibi it due to .the presence of a substantial percentage of soap, at least 5%and preferably from 10% to 20%, and likewise a substantial proportion of an oil- I soluble copper-compound, preferably 8% to 10%. The foregoing formulas are therefore proportioned so as to provide an amount 'of soap adequate to render the copper-laden oil properly miscible. f J
