Description

FFlQE.
LOUIS A.
CRETSING ER, OF DESHLER, AND JOHN A. WORKMAN,
F CLEVELAND, OHIO.
TIMBER-PRESERVIN G COMPOSITION.
No Drawing.
To all whom it may concern:
Be it known that we, LOUIS A. CRETSINGER, and JOHN A. WORKMAN, citizens of the United States, residents, respectively, of
Deshler, county of Henry, and State of Ohio, and Cleveland, county of Cuyahoga,
and State of Ohio, have invented a new and useful Improvement in Timber-Preserving Compositions, of which the following is a specification, the principle of the invention being herein explained and best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.
Our invention relates to the preservation of timber, its object being to treat timber in an economical and efiFicient manner with an improved timber preserving composition so as to enable it to resist chemical or other actions to which it may be subjected in the course of its use.
The said invention consists of the means and steps hereinafter fully described and particularly set forth in the claims.
In utilizing our above-described invention, we first take the wood to be treated and bore in same a number of holes of a size and distance apart depending upon the size of the timber to be treated. For instance, in t0 the case of railroad ties, we prefer-to bore one hole at each end of the tie and two holes in that part of thetie which would lie between the rails and on the top, said holes to be about a" in diameter and about 3 or 4;"
r deep. After these holes have been bored,
we inject into same a composition consisting of sixteen (16) parts of sodium chlorid (common salt), six (6) parts of powdered ,arsenic as popularly known, really arsenic trioxid, and one (1) part of mercurlc chlorid I (corrosive sublimate). amount of this mixture is injected into each hole which will plug to be inserted to stop the. hole. Such plug is inserted in each hole, and the material is allowed to remain in place. After a suitable length of time the preserving composition disseminates itself throughout the fibers of the timber and eventually reaches all parts thereof. Although the exact proportionsgiven have been found by us to be the best, they may be somewhat varied Specification of Letters Patent.

Application filed November 20, 1916. Serial N 0. 132,292.
and still satisfactorily accomplish the purpose of mercuric chlorid, which, in addition to as sisting in the preservation, also spreads or scatters the composition through the treated wood, being from one-half (7}) of one (1) part to two (2) parts, in the sodium being from twelve 12) to twenty (20) parts, and in thearsenic trioxid being from four (4:) to eight (8) parts.
e have found that timber so treated, particularly railroad ties, pilings, etc., successfully resists all ordinary chemical actions to which the timber becomes hardened, resists tendencies to check and crack and renders eflicient service for a greatly increased length of time over that furnished by untreated timber subjected to the same uses.
Having fully described our invention, What We claim and desire to secure by Letters Patent is l. A composition of matter for the preservation of timber, consisting of an admixture of amaj or portion of sodium chlorid, with an arsenical compound, and a mercuric compound in suficient quantity to spread or 7spatter the composition throughout the tim- 2. A composition ofmatter for the preservation of timber, consisting of an admixture of a ma or portion of sodium chlorid, with composition throughout the timber.
composition of matter for the preservation of timber, consisting of an admixture chlorid, four to eight parts of arsenic trioxid and one half part to two parts of mercuric chlorid.
4. A composition of matter for the preservation of timber, consisting of an admixture of substantially sixteen parts of chlorid, six parts of arsenic trioxid and one mercuric chlorid.
5. A method of preserving wood which consists in boring holes in the wood at suitable distances from each other, inserting a preserving composition in said holes consisting ofa major portion ofsodium chlorid, with an arsenical compound, and a mercuric chlorid sompmmd "121 suficiem quamfiy to s: reafi. 01 by 10-9, ibis 162321 Kay 01 Nwemben Sammy the camp osinisn throughout lififi mod, 1916.
