Description

UNITED STATES PATENT QFFIGE.
AROHIBALD MGNIOOL, OF YPSILANTI, MICHIGAN.
IMPROVEMENT IN CEMENTS FOR RENDERING LEATHER WATER-PROOF.
Specification formirg part of Letters Patent No. 153,680, dated August 4, 1874; application filed July 17, 1874.
To all whom it may concern:
Be it known that I, ARCHIBALD MoNrooL, of the city of Ypsilanti, county of Washtenaw and State of lllichigan, have invented a certain compound called MeNicol Cement, to be used instead of blacking, oil, or gum in rendering leather impervious to Water, and also to be used instead of stitching, or any of the various cements now in use, for cementing together separate pieces of leather.
This invention relates to that class of compounds used for rendering leather, and especially boots and shoes, impervious to water, and also to that other class of compounds used for cementing leather; and it consists of a composition formed by dissolving one part of india-rubber With one part of gutta-percha and ten parts of balata, in suflicient chloroform to render the compound of the consistency of common molasses.
To prepare the McNiool cement, take a bottle or other vessel that can be tightly closed, and after putting in theindia-rubber, guttapercha, and balata, add a small quantity of chloroform, and as the mass dissolves add chloroform to brin it to the required consistency.
To render leather impervious to water, rough the grain, and apply a coating of the McNicol cement. This willrender it completely waterproof, and still leave it as pliable as before the application; and in case of split leather tially as and for the purposes hereinbefore specified.
AROHIBALD McNIOOL. Witnesses:
J. WILLARD BABBITT, GEORGE E. ANDERSON.
