UNITED STATES PATENT OFFICE ROBERT BLAKE, OF PONTIAC, ILLINOIS.
IMPROVEMENT IN THE PROCESSES OF TANNING LEATHER.
Specification forming part of Letters Patent No. 144,500, dated November 11, 1873; application filed October 18, 1873.
To all whom it may concern:
Be it known that 1, ROBERT BLAKE, of Pontiac, in the county of Livingston and State of Illinois, have invented a Tanning Gompound, of which the following is a specification:
This invention has relation to liquors for tanning skins in the manufacture of leather; and it consists in the combination of muriatic acid, saltpeter, and common salt in certain proportions with soft water and terra japonica, as I will now explain.
For the treatment of, say, four hundred pounds of raw hides, after they are limed, bated, and treated by the old process of barktanning, I employ the following ingredients:
Soft water, one hundred gallons; muriatic acid, eight pounds; saltpeter, two pounds; common salt, ten pounds; terra japonica; fifty pounds. f
Instead of the terra japonica, bark extract or ooze may be used.
This forms the tanning-liquor, and the times required for treating different grades and kinds of hides with it are as follows: For sheep and deacon skins, from two to four days; calf and kip skins, from six to eight days; heavyica, or its equivalent, make a tan-liquor of superior quality.
I claim as,new
The tanning-liquor composed of the ingredients and mixed together in about the proportions specified.
In testimony whereof I have signed my name to this specification before two subscribing witnesses.
ROBERT BLAKE.
Witnesses:
L. E. PAYsON, E. M. RILEY.
