Description

GEORGE A. HENDERSON, OF ST. ALBAN S, WEST VIRGINIA.
IBIT'O'MINOUS BINDER AND PROCESS OF MAKING SAME FROM COAL-TAR PITCH.
Specification of Letters Patent.
Patented May 14, 1918.
No Drawing. Original application filed February 14, 1916, Serial No. 78,514. Divided and this application filed July 30, 1917.
To all whom it may concern:
Be it known that I, GEORGE A. HENDER- SON, a citizen of the United States, residing at Highland Villa, St. Albans, in the county of Kanawha, State of West Virginia, have invented a new and useful Improvement in Bituminous Binders and Processes of Making the Same from Goal-Tar Pitch, of which the following is a full, clear, and exact description.
My object is to produce a plastic binder of superior ductility, in which arepresent coal tar pitch, and sulfur.
It has been heretofore proposed to absorb the sulfur from natural sulfur-bearing asphalts by heating the asphalt in the presence of added petroleum or other oils.
My invention relates especially to a bituminous binder in which the oily constituent is added to coal tar pitch in sufficient quantity to absorb previously added sulfur during volatilization and driving oil of added petroleum, and in carrying out my invention the oily constituent is used to absorb previously added sulfur to render the product of especial value in binding such vegetable fibers as are referred to in my pending application for fibrous composition and process for making the same, filed February 12, 1916, application No. 77953, and my Patent Nol. 1,18 ,314 of 1916. tab
11 carrying out my process coal tar pi as produced as a by-product of coking coal,
Serial No. 188,597.
is mixed with from 6% to 14% of sulfur, depending on the quantity of bitumen present in the pitch, which sulfur has been previously mixed with a suificient uantity of petroleum to cause the sulfur to ecome absorbed in the mass when the mass is subjected to a temperature of approximately 400 deg. Fahr. a sufiicient length of: time to drive 01? the petroleum.
During volatilization of the oily constituent the sulfur is entrapped and retained in the resultant product, rendering it more duetile in cold weather, and less liable to become soft in hot weather than if not so treated.
I claim:
1. The process of producing a bituminous binder, which consists in mixing coal tar ,pitch with petroleum, and from 6% 14% of sulfur, and then subjecting the mixture to sufiicient heat, a suflicient length of time to drive ofi' the petroleum.
2. A bituminous binder consisting of from 6% to 14% of sulfur, and from 86% to 94% of coal tar pitch.
It witness whereof, I have afixed my nature in the presence of two witnesses this 23rd day of July, 1917.
GEORGE A. HENDERSON.
