, LIQUID IDENTIFICATION Filed March 10, 1928 INVENTOR Patented Jan. 6, 1931 FRANK C. REILLY, OF NEW YORK, N. Y.
LIQUID IDENTIFICATION Application filed March 10, 1928. Serial No. 260,721.
and made recognizable to the users of the I same by small markers such as letters, initials or arbitrary symbols of about the same specific gravity as the oil so as to remain in suspension therein and flow freely in the pouring of the oil. These characters intermingle and distribute themselves more or less evenly throughout the oil without settling or on the other hand, floating to the surface and may be of such a nature as to dissolve and add certain lubricating qualities to the oil under the influence of a definite rise in temperature.
In the accompanying drawing, practical embodiments of the invention are illustrated.
Thus, in Figure 1,.letter symbols supplying the trade name of the oil are mixed in the oil so as to pour freely therewith.
Figures 2, 3 and 4 are detail views illustrating other forms of identifying characters. In Figure 1 numerous letter symbols5 are shown, formed of some suitable oily or other material, which with heat will become soluble in the body of oil 6. These letter symbols may supply the name, trade-mark, grade or otherwise identify the oil and while naturally they will not arrange themselves in the order to supply the trade name, grade or other identifying characteristic, they will be selected .with a view to afiording the desired identification,'even in their more or less jumbled state.
In the illustration just considered, six dif ferent letters are employed to supply the entire word, but if desired, only letters forming the initials or certain striking letters in the word may be selected. For example, in Figure 2, symbols in the form of circular figures 7 may be used. Figure 3 illustrates the use of star shaped identifying characters 8 and Figure 4 illustrates a fanciful character 9 made up of a combination of two letters.
The identifying symbols may have a natural color or be colored artificially to make them stand out in the liquid and they may be placed in the liquid at the time of manufacture .or subsequently, for instance, at a time when the liquid is packaged by the manufacturer or distributor.
The composition and specific gravity of the identifying characters will vary, depending upon the fluids in which they are used and they may be given characteristics for improving the quality of the fluid or for qualifying it in some other way. For example, in the case of fluids such as table syrups, the identifying characters may be made of sugary material spiced or flavored to give zest to the product, and in the case of lubricating oils, the identifying characters may be of an oily, greasy or similar material or materials for preventing carbon formation.
What is claimed is:
As a new article of manufacture, means for identifyinga liquid, comprising readable characters having a selected definite significance designating origin .or other desired characteristic or quality of the liquid, said characters being of a.- material having a specific gravity so related to that of the liquid as to float in a state of suspension in the body of liquid and be thereby distributed substantially uniformly throughout the liquid, said identifying characters being soluble in the enveloping liquid under influence ofheat.
In witness whereof, I have hereunto set my hand this 20th day of January, 1927.
