Description

UNITE s 'rns PATENT orn on.
GEORG- HARTMANN AND OSKAR LALWI N SC HWERDTNER, OF GROSS SCI IGNAU, NEAR ZITT'AU, GERMANY.
METHOD OF PRESERVING WOOD.
No Drawing.
To all whom it may concern:
Be it known that we, Gnone HARTMANN,
- a subject of the King of Saxony, residing at Gross Schtinau, near Zittau, in Saxony, Empire of Germany, and OSKAR ALWIN SOHWERDTNER, a subject of the King of Saxony, residing at Gross Schonan, near Zittau, in Saxony, Empire of Germany, have invented a certaln new and useful Im roved;
Method of Preserving Wood, of which the following is a specification.
This invention relates to a method of protecting Wood against dry-rot and other Wood destroying agents characterized by treating the objects attached by such agents or threatened with infection with a solution of sodium-zincate. Such solution is prepared by mixing a solution of chlorid of zinc with caustic soda (sodium hydrate) in excess. For instance we dissolve 300 parts by-weight of chloridzofzinc'in 1000 parts of water and add to this a solution of 900 parts of caustic soda in 4000 parts of water. By applying two coats of this compound to wood, the.
same will be protected throughout against the destroying action of dry-rot or other organic Wood-destroying agencies, and, if the wood be already attacked, the destroying organism is completely extirpated. 7 By the combination with sodium zincate Specification of Letters Patent. Application filed January 17, 1910. Serial No. 538,548.
Patented Nov. 8, 1910.
of sodium hydrate in excess, the alkali forms with the chlorin of the zinc chlorid, sodium chlor1dor ordinary salt. The presence of the sodium chlorid increases the diffusibility of the sodium zincate and thus renders possible a much better impregnation of the wood.
This method, compared with other methods for the same purpose, has the ad vantage that it may be carried out at ordinary temperature and that the woodwork or other object treated is in, no way rendered unsightly or injuriously affected in'any respect. v I
What we claim as our invention and desire to secure by Letters Patent is:
1. The method of preserving wood, which consists in applying thereto a solution of sodium zincate and sodium chlorid.
2. The method of preserving wood which consists in applying thereto 'at the ordinary temperature a solution. of sodiumzincato and sodium chlorid.
In testimony whereof we have signed our names to this specification in the present-e
