IMPROVED MODE OF PREPARING INFLAMMABLE LlQUIDS 80 AS TO PREVENT ACCIDENTS.
Specification forming part of Letters PatentN 0. 6,987, dated March 28. 1866.
. clare that the following is a full, clear, and exa'ct description thereof and of its mode'or manner of operation.
The nature of my invention consists in givingto oils and fluids which are explosive or which easily catch fire from cont-act with a flame or spark, and which are or may be used for illuminating purposes and for other uses,
a bright and distinctive color, so that they may easily and certainly be distinguished from other oils and fluids. The object or purpose of so preparing and treating such oils and fluids is to guard against their use, by mistake or otherwise, in the place of those which naturally resemble them, and which are non-explosive and harmless.
Many of the very volatile and explosive fluids which are now used for illuminating and other purposes resemble so nearly in appearance, color, smell, &c., others that are entirely or almost wholly non-explosive and capable of being used with entire safety that they can be distinguished from each other .even by those who are familiar with such articles only with great difliculty, and cannot be so distinguished, or at least with any certainty, by ordinary persons. As a consequence there is great danger that accidents, and often of avery serious character, will-happenfroui a mistaken or negligent use of such explosive and inflammable fluids under the supposition they were nonexplosive and harmless, whereas there would be but very little, if any, danger of the happening of any such accidents could such explosive fluids be readily distinguished from others. To guard against the liability of such accidents it becomes therefore extremely de-' sirable that those fluids which are explosive and inflammable should' be so prepared or treated that they can quickly and certainly be distinguished from all others. This object I secure by giving to such explosive and inflam mable oils and fluids a bright distinguishingcolor-as red, blue, or yellow-which will quickly and effectually arrest the attention of those using such fluids. and at once indicate the true nature and character of the article so colored and cause a careful use of such fluids, or guard against their use in the place of oth- A red color can be given such oils or fluids by the use of 'alkanet root or aniline, a blue color by the use of Prussian blue or indigo, and a yellow color by safi'ron or turmeric.
The red color I, prefer because it presents a greater contrast to the ordinary appearance of such fluids. The explosive and inflammable fluids are colorless, as are also those even explosive, and hence there is greater danger of accidents such as have been referred to happening so long as such different fluids are not plainly distinguished from each other. A practical and somewhat extensive application and use of fluids so distinguished by some such bright color has satisfactorily proved the value of this method of preparing such fluids, and has demonstrated that when-so treated they can be used without danger or liability of accident. mable fluids which will easily take fire from contact with a flame or spark, such as benzioe, camphene, alcohol, pyroxylic spirits, naphtha, and all other essential oils, and-many of which are now used in lamps, fixed and portable. By such treatment, also, a bright and beautiful appearance is giveu'to the lamp, as well as protection secured.
Other colors than those vabove named may be employed, it being only necessary that the color used should plainly distinguish the fluid.
What 1 claim as my invention, and desire to secure by Letters Patent, is-- Giving to explosive and inflammable oils and fluids used for illuminating and other pur poses a bright distinct color to plainly distinguish them from other oils and fluids, substantially as and forthe purposes set forth.
