UNITED STATES FRANK W. BARBER, OF NASHVILLE, TENNESSEE.

INSECTICIDE.

No Drawing.

To all 11 71 0112, it may concern:

Be it known that I, FRANK l V. BARBER, a citizen of the United States, residing at Nash-ville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Insecticides, of which the following is a specification.

7 This invention relates to insecticides, and particularly to insecticides which are designed to protect animals from flies.

The general object of the invention is to provide an insecticide which maybe applied to the coats of animals for the purpose of driving off flies and preventing animals being annoyed by flies.

A further object in this connection is to provide an insecticide which may be sprayed upon the coat and which under these circumstances does not injure the hair or hide of fancy cattle or other animals, and which is particularly valuable in preparing the coats of animals before bringing them into the show ring.

A still further object is to provide an insecticide of this character which has a pleasant odor instead of the usual offensive odor which is characteristic of the ,fly sprays at present on the market, and which will kill flies immediately.

Another object is to provide a spray of such composition that this compound may be sprayed in the form of a mist which will coat the body of the fly, mosquito or other insect, clogging or stopping up the breathing apertures in the sides of the body of the insect, thus resulting in the insects dying of suffocation.

My improved compound consists of a mixture of substantially the following ingredients in the proportions stated :Paraffin oil 80%, kerosene oil 16%, oil of mirbane 1.5%, oil of citronella 1.125%, oil of pennyroyal 375%, naphthalene 1%. It will be understood that the above percentages are in volume. Another way of stating the formula in liquid measure is as follows Para-flin oil 5 gals, kerosene oil 1.gal., oil of mirbane 12 liquid 0zs., oil of citronella 9 liquid 02s., oil of pennyroyal 3 liquid ozs., naphthalene 8 ounces by weight, avoirdupois. It will be understood, of course, that the naphthalene is a powder.

The above ingredients are mixed as follows: The paraffin oil and kerosene oil are thoroughly mixed together in the first in- Application filed June 17, 1924. Serial No. 720,658.

pouring back and forth, it being essential to secure a thorough mixture of all of the ingredients.

Paraffin oil is used as the base of the composition and for its killing properties. Kerosene is used to thin the paraffin and also for its killing properties. The

oils of mirbane, citronella and. pennyroyal are used for their odors as well as for their repellent properties. The oil of pennyroyal is somewhat expensive and hence a certain proportion of the oil of mirbane is used in the formula which is less expensive. The oil oliuirbane might be omitted and 1.5% oil of citronclla and 1.5% oil of pennyroyal used instead. Furthermore, while the percentages given in the first formula are preferable, the following percentages might be used :Paraitin oil 75% to 85%, kerosene oil 2 "a to 12%, oil of mirbane 2% to oil of citronella 1%, oil of pennyroyal 1%, naphthalene 1% to It will be seen that these percentages as first given may be varied to a considerable degree within the limits hereinbefore stated.

These percentages as herein given are based upon liquid measure with the exception of the naphthalene which, as before remarked. is a powder. Naphthalene by weight and by liquid measure is approximately the same.

The naphthalene is absorbed by the aromatic oils and remains in solution. The naphthalene is used for its repellent properties and combining it with the other ingredients'does not destroy its effectiveness nor interfere with the action of the others. My experiments have shown me that when the oils of citronella and pennyroyal are combined, or citronella and mirbane are combined, or citronella, mirbane, and pennyroyal are combined, the coaction is such as to produce an odor that is more offensive to flies than is the odor of any one of these oils by itself. The odor of all of these oils is pleasing to human beings but offensive to fliesand the ofiensiveness of the odor, as far as flies is concerned, is increased by combinin the oils.

As before remarked, the oil of mirbane ma beleftout and citronella, penn royal an naphthalene alone used. It is o vious that combinations of mirbane and citronella or citronella and pennyroyal or mirbane and pennyroyal may be used and that the proportions of these three odoriferous ingredients may be varied in many ways and also that the proportions of the kerosene oil, the parafiin' oil and the naphthalene may be varied in many ways. The kerosene oil and the paraffin oil combine so that the injurious effect which would be produced if the kerosene oilwere used alone is counteracted by the parafiin without, however, destroying the killing action of thekerosene oil, but my experiments have shown me that the effect of using the two in combination is decidedly difierent from that where either one or the. other is used alone.

This compound does not in any way injure the hair or skin of the animal to which it is applied and in point of fact this c0mpound might be sprayed into the eyes or months of animals without any injury since it is not poisonous or caustic in its action. There is nothing in this com ound which tends. to gum the hair or ren er it stiff or dull. It will be seen that this compound does not contain carbolic acid, which would be a rank poison, or creosote which is also very poisonous and irritant to the skin of animals, nor does. it contain a large percentage of kerosene: Any compound containing a large percenta e of kerosene, if put on an animal more t an three or four times, would act to remove the hair and blister the skin.

I do not wish to be limited to the percentages which are stated, as it is obvious that. these percentages, particularly the per-.

centages of the aromatic oils and ofthe naphthalene, may be varied in many ways without departing from the spirit of the invention. 4

I claim v 1. A li uid insecticide for spraying animals consisting of the following ingredients in approximately the following proportions: Paraflin oil to kerosene oil 20% to 13%, naphthalene oil 2% to 1%, oil of citronella 2% to oil of pennyroyal 1% to 2. A liquid insecticide for spraying animals including the following ingredients in substantially the following proportions: Kerosene oil 20% to 13%, paraflin oil 75% to 85%, oil of mirbane 1% to 0%, oil of citronella 2% to 1%, oil of pennyroyal 1% to naphthalene 1% to 1 In testimony whereof I'aflixmy signature.
