Description

PETER c. REILLY, OF INDIANAPOLISQINDIANA.
PRESERVED WOOD.
. Specification of Letters Patent.
Patented Sept. 29., 1908.
Application filed January 1906. Serial No. 294,604. (Specimena) To all whom it "may concern:
Be it known that I, PETER'C. REILLY, of Indianapolis, county of. Marion, and State of Indiana, have invented acertain new and useful Preserved Wood; and I do hereby declare that the following is a full, clear, and exact description thereo My invention. is an article of manufacture consisting of natural wood impregnated with a product of the destructive distillation o petroleum and creosote oil. This invention is in the nature of an impro'vefnent over that set forth in a former application by me, filed August 31, 1905, Serial No. 276,622, for preserved wood, wherein was described the sofurceand manner of producing, from petroleum, a product from which the etroleum product herein mentioned is obtained.
The following is a description of the equipment and process for obtaining and the char. acteristics of the petroleum product (one of the constituentsherein required) and also the manner of mixing the two constituents. The apparatus consists of a cylindrical retort having .an ironshell lined inside with fire clay and loosel filled with pieces of broken- -fire brick or li e refractory material. One
end of the retort is rovided with an openin and appliance for eating thecontents an also a suitably arranged spray pipe connected with a supply tank containing oil. The other end of the'retort is provided with a sort of stack valve and-also a pipe connecting a condensing chamber and reservoir for collectin such condensable matter and gases as may roduced by the process hereafter described? The starting material must be a crude petroleum or petroleumdistillate, having a paraffin base.
In-oper'ation thetemperature of the con- ,-tents of the retort is raised to a cherry red vapors and fixed gases.
heat and thena spray of the petroleum oil is injected into it and caused to pass'up through the red hot material. The hea'ttransforms the constituents of the oil into condensable These products are conducted thrr igh the coolin chamber -where the vapors condensean' the fixed gases ass on to the reservoir where they are storec The black oily liquid which is collected in the condensing chamber is the product which ploye V What I claim as my invention and desire to .nesses herein named.
I dissolve in the creosote oil. This hydro carbon oil has a specific gravity of about 1.0725, begins to distil at about 150 C., is fluid at normal temperatures, is substantially non-volatile and practically free of suspended matter. I place the condensed liquid in a suitable retort and raise itto a temperature ofabout 300 F., then add the creosote oil in substantially equal parts andcause the ingredients to be thoroughly mixed.
In combining these ingredients I have usu ally used about half and half but this propor tion is not necessary and I do'not wish to be limited strictly to it. I find that WllGIliJliiS petroleum productis mixed with the creosote oil, the resulting mixture is a striking and novel product very valuable as a wood preservative.
The mixture possesses a higher specific gravity than that of the creosote oil alone, yet retains a degree of enetrability equal to that of the creosote oi On account of the addition of the etroleum product to the creosote oil the mixture obtained possesses a superior value over the creosote oil alone, since it gives to it a body which will offer more resistance to atmos )heric elements and surfacewear of the woo fiber impregnated with this mixture than wood fiber treated in like manner with creosote oil.
The above described mixture is driven into the pores of the wood fiber in any suitable way, (preferably by the usual methodsemfor creosotlng woodl secure by Letters Patent is:
As an article of manufacture, wood 1mpregnatedvwith a mixture of creosote oil and the hereinbefore described tar obtained from the manufacture of oil and. water gas, said tar having a specific gravity greater than water, beginning to distil at about 150 (3., fluid at normal temperatures, substantially nonvolatile, and practically free of suspended matter. 1
In witness whereof, I have hereunto affixed my signature in the presence of the wit- PETER c. REILLY.
