SPECIFICATION forming partof Letters Patent No. 317,125, dated May 5, 1885.

Application filed July 9, 1884. (No specimens.)

To all whom it may concern.-

Be it known that I, HENRY HALES, a citizen of the United States, residing at Ridgewood, Bergen county, New Jersey, have invented certain Improvements in l/Vood-Fillers, of which the following is a specification.

The purpose of my invention is to provide a composition for filling the grain of wood in the process of finishing the latter. Many substances and compounds of substances have been employed for this purposesuch as starch, ground Indian corn, powdered flint, quartz, clay, &c.-some of which have been discarded, while others have produced measurably good results; but in all cases, so far as I am aware, the users have been compelled to employ two compositions, one for dark and the other for light woods, as the composition adapted for light woods would leave white specks and streaks on dark woods. This employment of special compositions for the different woods has serious disadvantages when employed on mosaic work, or any work where light and dark woods are brought into juxtaposition, as the dark composition will injure the appearance of the light woods, and the light composition that of the dark woods.

My object is to furnish a filling composition of a transparent nature that may be used on all woods indifierently. To light woods it imparts only sufficient color to full-y develop the grain, which the ordinary light fillers do not do, and when used on dark woods its transparency is such that it leaves no perceptible mark of its presence. Thus I am enabled to use it with excellent results on mosaic or inlaid work made up of woods of all kinds. I also avoid the use of all coloring-pigments, such as are commonly employed in such compositions to match the woods, and which always produce a muddy effect and obscure the natural grain of the wood.

My composition comprises finely-powdered soapstone or talc, finelypowdered glass or other similar transparent or nearly transparent substance, and a suitable liquid vehicle, which is or may be oil or Japan varnish. The soapstone enables the operator to obtain a better polish than could be obtained with the glass alone.

In making and using my composition I usually proceed as follows: I mix together, dry, about equal parts, by preference, of powdered glass and powdered soapstone, and then add enough linseed-oil to form a thick putty-like mass. To this I add Japan varnish in quantity sufficient to reduce the mass to the consistency of cream. This may be suitably thinned with oil or turpentine before using, if desired or necessary. I apply the filling composition with a brush in the usual way, and when set or thickened rubit well into the wood. The surplus should then be rubbed off with clean rags or shavings. This produces a hard highlypolished, glossy surface which is not affected by dampness.

My compound is a mere mechanical mixture, there being no'noticeable chemical reactions when the ingredients are brought together. Therefore a variation in the proportions of the vehicle used is not a very essential matter. The following proportions, however, will produce good results, and may be followed with confidence. Tofifty pounds each of powdered soapstone and powdered glass add ten quarts of linseed-oil and six quarts of Japan varnish.

, I prefer linseed-oil and Japan varnish, but cotton-seed oil and copal varnish, for example, may be substituted therefor. As the Japan is used as a drier to cause the compound to set quickly, the proportion of copal varnish would require to be somewhat greater than that of the Japan, as it is less effective than the latter as a drier.

The proportion of soapstone added tothe compound may be varied considerably without injury. Its function is mainly to enhance the polish, and I have given what I consider about the best proportion where the composi- 1.
