Description

f atentecl Nov. 7, 11922 UMTEEL) sraras E ATENT CODFFHQEO WILSON TAYLOR, or TORONTO, ONTARIO, CANADA.
No Drawing.
To all whom it may concern 'Be it known that I, WILSON TAYLOR, a subject of the King of Great Britain, of the city of Toronto, in the county of York, 111 the Brovince of Ontario, Canada, have invented certain new and useful Improvements in Processes for Preventing the VVater-Loggmg of Nonresinous Woods, of which the followin is a specification.
Iy invention relates to improvements in processes for preventing the water-logging of non-resinous woods and the object of the invention is to devise means for preventing logs of non-resinous wood when floating upon the surface of the water down stream from becoming water-logged. My process consists of heating the surface of the log above the temperature of the liquid to be applied thereto and then applying a coating of heated water proofing material so that it will impregnate the heated surface of the wood and solidify when cooled, then suddenly chilling the wood to prevent saturation by the waterproofing liquid beyond a predetermined depth.
I will now describe my process in detail. After the cutting of the standing timber, the logs resulting therefrom are dried out by the weather. so that their specific gravity is less than that of water to enable them to float even for a few minutes. The ends of the logs are then rapidly heated by a blast of -hot dry air or by the application of a heated plate of iron for a few seconds of time or by any other suitable means to a temperature above the temperature of. the liquid to be afterwards applied so that Application filed February 26, 1921. Serial N0. 448,240.
After the paraffin is hardened the ends are agaln swabbed two or three times to leave a thick impenetrable coating which effectuall prevents the water from entering the woo If the specific gravity of the wood is near that of water 'the bark should be removed from the tree when out and the sides dried by the weather as far as possible, then heat is applied to the surface of the wood either by a blast of hot air or by ahot plate pass- 1ng over the wood in close proximity thereto, the heating of the wood being followed by a single swab of hot paraffin. The effect of this is to prevent for a long time the ab iorption of water through the sides of the lVhat I claim as my invention is:
1. A process for preventing the waterlogging of non-resinous woods while in the logs-from which the bark has been removed consisting of first weather drying the log until it has a specific gravity less than water, then rapidly heating the surfaceof the log to a temperature above the melting point of paraffin, then swa-bbing such surface while heated, with melted paraffin, and finally immediately after swabbing suddenly cooling the heated portion of the log to retain the paraffin closely adjacent to the surface of the log, thus forming an exterior strata of wax impregnated fibre extending over the whole surface of the log.
2. A process for preventing the water-' logging of non-resinous woods, consisting of first weather drying the log until it has a specific gravity less than water, then rapidly heating the surface at the end of the such liquid will readily penetrate and not log, then swabbing the heated surface with become chilled by contact with the wood.
Immediately after the heating, the ends of the logs are swabbed over two or three times with melted paraffin. After this operation is complete, the wood is suddenly cooled by applying a fine spray or stream of water thereto so as to prevent the paraffin saturating the wood too far, the object being to form a thin covering of saturated wood fibre which will prevent moisture passing therethrough into the body of the wood and yet at the same time not to saturate any more of the wood than is necessary to accomplish this result as the saturating of the wood destroys its quality.
melted paraffin, then chilling such surface to heating the surface of the wood to a temperature above the melting point of paraffin, applying the melted paraffin to the logs' surface whereby the paraffin, exterior to the fibres, is carried into the stratum to serve as an air seal extending over the surface of the log, and then chilling the surface to prevent the paraffin entering deeply beneath the surface of the log.
WILSON TAYLOR.
