CHARLES MQGONNELL, JR, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN COMPOSITIONS FOR VARNISH.
Specification forming part of Letters Patent No. I 74,834, dated March 14, 1876; application filed July 2,
To 0' whom it may concern:
Be it known that I, CHARLES McGoNNELL, Jr., of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented a certain new and useful Elastic Varnishing, saturating, and Painting Oompound; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it.
The object of my invention is to provide a substitute for linseed-oil, and which can he used'for mixing .paints, for varnishing wood, metal, 860., and for saturating roofing felt and paper.
Take titty parts of rosin; twenty-five parts of henzine; twenty parts ot'gas-tar; five parts of sugar-of-lead. The rosin and gas-tar are heated in separate vessels until the former beand half of the benzine added to each-serving to keep the rosin from hardening, and producing a precipitation of the heavy impure matters in the gas-tar. The clearedgas-tar is then drawn off and poured into the fluid rosin, and the sugar-of-lead immediately added to the mass;
Five parts of linseed-oil may be substituted for an equal number ot" parts of benz'ine or added to the given quantity of the latter.
It is notabsolutely necessary to adhere strictly to the exact proportions given, and they may, if desired, be varied as taste and experience will suggest. I
The above-described compound diiit'ers from that of Averell in his Letters Patent N 0. 19,7 29, in that while he uses water, acetate of lead, spirits of turpentine, and coal-tar, he does not make any use of resin or benzine, bot-h of which are a partot' applicants invention.
I claim- The improved composition varnish, consisting of rosin, benzin", gas-tar, and sugar of-lead, as and for the purpose specified.
In testimony that 1 claim the foregoing I have hereunto set my hand this 28th'day of June, 1875.
