WOOD-FILLING COMPOUND.

SPECIFICATION forming part of Letters Patent No. 658,271, dated September 18, 1900.

Application filed July 13, 1898. Serial No. 685,368- (No specimens.)

To all whom it may concern.-

Be it known that I, EDWARD A. MEYER, a citizen of the United States, residing at Fruitvale, in the county of Alameda and State of California, have invented certain new and 7 use in connection with polishing, varnishing,

or painting of .woodwork, the object being to provide a. compound, which will quickly penetrate into the woodwork and by filling the pores thereof give a smooth even surface upon which to apply the polish, varnish, er

final coat of paint.

In carrying out my invention I first provide a base consisting of a solution of sodium biborate and water, having dissolvedtherein a given quantity of lacca in tabulis or orange shellac, the parts being in about the following proportion; sodium biborate, six ounces; water, one hundred ounces; lacca in tabulis, twelve ounces. The solution of sodium bi-. borate and water is preferably raised to boiling-point prior to the introduction of the lacca in tabulis. This produces a liquid mixture which is reduced to the consistency of ready-mixed paint'by intermixing therewith a given quantity of finely-powdered mineral substance, as pumice-stone. and talc, in equal proportions-that is, to a mixture as above specified about twelve (12) ounces of finely-powdered pumice-stone and twelve (12) ounces of finely-powdered talc are intermixed;

The compound thus produced is applied to the surface of the woodwork to be treated by means of a brush and while in a wet or undried condition is thoroughly rubbed into the pores of the wood by means of a cloth or paper until dry, when p the pores of the wood will be filled and a smooth surface provided to receive the polish, varnish, paint, or other finish to be given to the woodwork. Prior to applying the finish the compound should be allowed to set from fifteen to thirty minutes, according to the temperature and dryness of the air, seats to give the same ample time to harden.

By the use of the above-described filling compound the work of applying the finish is quickly performed and less of the finish is consumed than where applied directly to the woodwork and a smoother and more uniform finish is secured.

Any desired shade may be given to the herein-described wood-filling compound by simply adding thereto a small quantity of. mineral paint of the required color. The amount of mineral paint to be added is dependent upon the color required by the user of the compound, and no proportion can be given, as the same mustbe 'left to the good judgment of the operator.

By lacca in tabulis in this specification is meant the refined and pure article in con tradistinction to the r-aw shellac found in the market and which when extracted is known commercially as f lac dye. The raw shellac cannot be substituted in my compound for the lacca in tabulis. The sodium biborate employed by me is known by the formula lTa B,O 5HO and is not, to my positive knowledge,the same as all the so-called refined commercialborax, which is in many cases adulterated, particularly so when bought in a powdered state. In my composition to obtain the proper containing a coloring-matter and desired results the lacca in tahulis and sodium biborate must be employed.

.Having thus described my invention, What I claim as new, and desire tosecure protection in by Letters Patent, is-

The herein-described wood-filling com pound comprising the following ingredientsin substantially the proportions named: sodium biborate, six ounces; water, one hundred ounces; lacca in tabulis twelve ounces; and sufiicient powdered pumice-stone and tale to reduce the compound to about the consistency of ready-mixed scribed.

In testimony whereof I affix my signature, in presence of two witnesses, this 7th day of July, 1898.
