PROCESS FOR TREATING WOOD.

No Drawing.

T 0 all whom it may concern:

Be it known that l, FRANK J. TAYLOR, a citizen of the United States, residing at Phoenix, in the county of Maricopa and Territory of Arizona, have invented certain new and useful Improvements in Processes for Treating Wood; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful methods in treating woods and it is my obiect to provide such a method as will both beautify and make useful any wood whatsoever by nrst applying to the wood a liquid of moderately combustible properties and then changing the wood to a permanent dye by the application of heat.

It is well known that there are many soft woods which are almost colorless as to grain and practically invaluable for decorating purposes, due to the fact that no method of material value has ever been discovered which has been capable of bringing out the grains in such soft and colorless woods.

It is the object of this invention, therefore, to provide a method which will be especially valuable when applied to such soft woods, etc, and it is further the object to place the wood in such a condition as to be ready for staining so to represent many different kinds of colored woods giving beautiful decorative effects.

In carrying out my invention, I provide a process, which consists first in applying to the surface of the wood, after the same has been placed in a finished condition, a liquid of moderately combustible properties, the ingredients of which are mixed in the proportions of one (1) ounce of cobaltchlorid, two (2) ounces of water, one ounce of oil of cloves, live (5) ounces of glyccrin and one (1) quart of alcohol, in co balt-chlorid being first dissolved in water and the glycerin, alcohol and oil of cloves added in the order named. This liquid is applied smoothly with a brush to the surface of the wood, the soft grains thereof absorbing it to a certain extent, while the less porous portions of the grain will absorb a Specification of Letters Patent.

lesser amount. The surface of the wood thus treated is then allowed to dry, in which case about nine-tenths of the liquid applied will evaporate, the remainder thoroughly penetrating the soft portions of the wood, and the same surface is changed to a permanent dye by the application of heat from a pluinbers torch or the like, the degree of heat being only sufficient to slightly burn, scorch or char that portion of the wood grain which has absorbed the liquid so applied to the greater degree. Just suflicient heat is applied as will change the surface to a brown color, without afiecting the texture or fiber of the wood and without discoloring other well-defined portions of the grain of the wood which have not absorbed so much of the liquid so applied and without producing any unevenness in the surface of the wood so brought out in contact with the heat. After the grain has thus been brought out clearly, it can be stained to represent many different kinds of colored woods, or it is in immediate condition for finishing in oil, shellac or varnish, as may be desired, the results of which will be most beautiful.

It will be seen that I have provided a method that is most efi'ective in changing a material to a permanent dye by the application of heat to a surface, which has been thoroughly saturated with a liquid composed of the ingredients heretofore described.

What I claim is:

1. The herein described method of treating wood, consisting in treating the surface of the wood to a liquid formed of cobaltchlorid, water, oil of cloves, glycerin and alcohol and applying heat to the thus treated surface.

2. The herein described method of changing a wood to a permanent dye, which consists in treating the surface thereof to a liquid formed of cobalt-chlorid, water, oil of cloves, glycerin and alcohol; allowing said surface to dry and applying heat thereto.

8. The herein described method of changing the surface of wood to a permanent dye, which consists in treating the surface of the wood to a liquid formed of cobalt-chlorid, water, oil of cloves, glycerin and alcohol;

allowing said surface to dry until the greater portion of said liquid has evaporated and applying to the thus treated surface a de gree of heat, Which Will slightly burn, scorch or char that portion thereof absorbing the liquid to a greater extent.

In testimony whereof I have signed my name to this specification in the presence of two subscrlblng Witnesses.
