Abstract
295,126. Kobiolke, A. M. Aug. 9, 1927. Proofing against bacteria and fungi; proofing processes; wood, treating with liquids and gases.-A process for preserving timber and other materials and destroying insects &c. therein consists in applying a vacuum, forcing the preserving fluid, preferably creosote, by air pressure into the treating chamber, withdrawing the fluid, creating a high vacuum in the chamber, and suddenly releasing the vacuum to force the surplus fluid into the wood. Green wood may be first treated with live steam, and the preserving fluid may be heated by means of a steam coil in the chamber. The apparatus consists of an impregnating chamber 1 and a tank 2 for the impregnant, connected by a pipe 3 with valves 4. At the top of the tank 2 is an inlet nozzle 6 open to the air but which may be connected by a pipe 7 to a vacuum pump 8. The pipe 7 can also be connected to a valve 10 at the top of the chamber l. A steam coil 12 supplied from a boiler 13 s disposed at the bottom of the chamber. The timber is run into the chamber on trucks 19. The walls of the chamber are provided with heat nsulating linings 22, and gutters 23 are provided to carry off condensed liquid through pipes 24 to a vessel 25. The timber having been placed in the chamber, the latter is opened to vacuum through the pipe 7, and the pump operated to create a vacuum of about 25 inches. The valves 4 are then opened, and impregnating fluid is forced into the chamber from the tank 2 by atmospheric pressure until the timber is submerged. The fluid is allowed to remain for a period, after which the suction pipe 7 is connected to the tank 2 and the unused fluid is sucked back to the tank. A high vacuum is then created in the chamber 1, and suddenly released by removing the pipe 7, allowing the entry of air which forces the preserving fluid remaining on the surface of the timber into the pores thereof. In treating green timber, live steam is fed to the chamber 1 through an inlet 26 for a period sufficient to cause the sap to boil, and allowed to remain for one hour, after which a vacuum is created to withdraw surplus moisture. The previously described treatment is then applied.
