Description

UNITED STATES PATENT OFFICE.
WARREN IDDIYGS, OF IVARREN, OHIO.
PRESERVING AND HARDE NING WOODa QPECIFICATION forming part of Letters Patent No. 398,619, dated February 26, 1889.
Application filed December 20, 1838. Serial No. 294.211. (No specimens) To all whom it may concern.-
Be it known that I, WARREN Ioonvos, a citizen of the United Siatesof America, residing at \Yarren, in the county of Trumbull and State of Ohio, have invented certain new and useful lm wovements in a Process of Treating 'Wood, of which the following is a full, clear, and exact description.
The invention relates to certain new and useful improvements in a process of treating wood, by which the same is preserved and thoroughly hardened and rendered weatherproof, dc, and prevented from decay, all as will be hereinafter fully described, and specifically set forth in the claim.
In carrying out my invention I first use a composition of about the following propor' tions: concentrated lye or potash, two pounds; burnt lime, one pound; pulverized iron ore, two'ounces; alum and salt (saturated solui503) and water, two gallons. The above-described parts I mix with water and place, together with the wood, into a suitable iron vessel or tank and boil the solution a suitable length of time until the wood is well saturated with the solution. The result of this treatment is that all of the sap that may be in the wood is taken out and the pores of the wood tilled with the mixture, (such material as will not decay.) Otherwise, if there should re main any sap in the wood and the wood be exposed to the weather it would readily decay. After subjecting the wood to the abovedescribed process I then remove the wood therefrom and put it into another vessel or tank suitable for the purpose containing the following ingredients, viz: flaXseed-oil, one pint; petroleumoil, one gallon; rosin, one
the sap or watery parts are eliminated and the preserving material or mixture takes its place, thus insuring the preservatitm of the wood.
By the foregoing treatment or process to which the wood is subjected it willbe readily seen that wood so treated or embalmed will be durable, hard, and exempt from decay, does not shrink or swell, as other wood does, and is capable of a much finer finish.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-
The process or treatment of wood, as herein described, by which it is preserved, rendered hard and weather-proof, &c., consisting in subjecting it to a bath in a boiling solution composed of concentrated lye or potash,burnt lime, alum and salt, and pulverized iron ore mixed with water, and then subsequently immersing it with a hot solution composed of fiaxseedoil, petroleum-oil, rosin, red lead, or any suitable coloring-matter whereby the tint is given the wood, substantially as and for the purpose set forth.
In witness whereof I hereunto set my hand in the presence of two attesting witnesses.
WARREN IDDINGS.
