PROCESS OF TREATING AND COLORING WOGD AND PRODUCT OF SUCH PROCESS.

No Drawing.

To all whom it may concern:

arts for various purposes Without liability of change due to atmospheric or other conditions and the sustaining of a permanent homogeneous color throughout the wood or The object of the invention is to produce a colored wood impervious to. moisture and colored through and through.

A further object is to provide a vehicle for thoroughly impregnating wood or fiber and simultaneously using therewith a color which will hold and bind the impregnating material.

It is not new in the art to stain wood and fiber nor is it new in the art to impregnate to a greater or lesser extent such material with a water-proofing compound or a fireproofing compound. So far as known to applicant, such impregnation and coloring has acted only to certain depths upon the material. Foiinstance, in impregnation and coloring of wood the surface and what might be called a skin of varying thickness receives the treatment, but if crossjsawed or out there is non-uniformity in the coloring conditions as well as in-the imp-regnation. It follows that the articles tobe treated must be treated in given sizes and the impregnation will be substantially uniform up to certain depths from the surface on all parts of the article.

It is one of the principal objects of the present invention to thoroughly and completely impregnate the wood or fiber through and through and at the same time color it to any desired degree for any use to which it may be desired to utilize it.

' In carrying out the process, wood or similar fibrous material is used as the base which is to be treated and must be in a substantially dry condition to secure the quickest and best results in treatment. Wood which is suitably seasoned or kiln-dried may be readily treated and will, after subjection to the process hereinafter defined, maintain a constant condition both as to color and Specification of Letters.

holding qualities with reference to the impregnating materials.

In carrying out the process, various materials may be used, including a combination of waxes of difi'erent characters, of mineral, vegetable or animal origin combined with the products derived from volatile oils or produced by oxidization of hydro-carbons such as rosinsv and mixed with stearic acid or its ethers or glycerins or the commercial form of stearin, so-called stearic acid. The above materials are used in conjunction with suitable coloring materials preferably those which are solublein oils, such as one having an indulin' base made soluble with stearin or olein. Very excellent results have been obtained by mixing a quantityof carnauba wax with paraflin, rosin and coloring matter. The ingredients vary somewhat with the treatment to be produced but in any event the waxes, parafiin and rosins act as a conveyer for thoroughly impregnating the material with the coloring matter and when combined as hereinafter set forth act as a binder with the coloring matter so that the article treated has a definite and constant value of impregnating materials and coloring matter. v

In treating wood and fiber various artistic results may be secured by utilizing different coloring materials producing the various tints such as oak, mahogany, ebony, birch, maple, walnut, andin fact almost any of the natural woods and when the wood is once treated it may be readily polished and finished without staining other than that 1ntroduced at the time of treatment. Furthermore, the treatment has this great advantage, namely, that it shows any imperfections in the material to be treated. For instance, where wood is of imperfect form and has a streak of tight-grain or dry-rot 'or sap-grain, the color will immediately disclose the fact that the wood has not been properly impregnated and light streaklngs will show. Thus it is'possible to ascertain before attempting to use the finished product that it is a erfect piece of wood su1table for fine wor fine veneer cutting, etc.

In carrying out the process, the followmg ingredients are used: Saturated hydro-carbon of the general series having the formula CnH +2 in solid form, such as paraflin having a melting point between 40 and C. and boiling at 120 C. or higher; an am- 'mal, mineral or vegetable wax preferably it to the bottom gredients are matter, 3% lbs, in some cases paratively small proportion using a to the boiling poin terial to be treated oughly impregnated.

It has tions, will not absorb moisture, evaporate its impregnating solution.

that it may be cut in any form,

mixed 1n varying proportions, excellent results having been attained by a mixture as follows: paraifin 100 lbs., carnauba wax 20 lbs, rosin 20 lbs., coloring comb weight of stearic acid. They are reduced by subjecting to heat in a suitable vessel until raised There upon, the mais boiled in the mixture until it attains a gravity suflicient to carry of the caldron. This is the best indication that the material is thorbe'en found that wood treated in this manner shows no appreciable change of condition under varying atmospheric condiand will not s parently the coloring and impregnating material bind one another in the fiber of the wood and the impregnating material carries the color completely through the fiber so always show the :wood or fiber is greater than that of the solution.

2. The herein described process of treating wood and fiber which consists in subjecting said Wood or fiber to a boiling bath of paraflin, carnauba wax, rosin and coloring matter soluble in the said menstruum with substantially equal parts by weight of carnauba wax and rosin and an excess of paraflin.
