HIMSELF AND SAMUEL BLJENKS.
Letters Patent No. 110,465, dated December 27,1870.
IMPROVEMENT IN THE MANUFACTURE OF-LEATHER.
The Schedule referred to in these Letters Patent and making part of the same.
having a similar nature or effect, for the purpose of preventing to some extent the tendency of the fibers of the skins to contract and become hard and horny.
To enableothers skilled in the art to make and use my invention, I will proceed to describe its construction and operation. 7
I take plaster of Paris and mix it withwater to such a consistency that it can be readily applied to the surface of skins and at the same time will penctrate as much as possible into the skins; and I also take other substances of a similar nature and effect,
and apply either the plaster of Paris and water or the other similar substances to the skins while they are in a wet condition after coming from the tanning solntion and then allow the skins to dry. Thus I am enabled to efiect a great saving in the quantity of tanningmaterial to be used in the manufacture of leather, and at the same time to secure in this mode of manufacture leather possessed of some very desirable qualities...
What I claim as my invention, and-desire to secure by Letters Patent, is-
The use upon 'the surface of skins while they'are in a wet condition, after coming from the tanning solution, a mixture of plaster of Paris and water, or of other substances having a similar nature or effect, in order thus to prevent the skins from drying so hard that they cannot be readily softened, especially such skins as have not been in strong tanning solutions.
