Complete Specification Left, 5th Dec., 1894-Accepted, 5th Jan., 1895
I, WILHELM HERMAN JEANSSON, of 28, Dovenfleet, Hamburg, in the Empire
of Germany, Merchant, do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to the treatment of that kind of leather known as
"horse crup."
Horse crup leather after tanning in the ordinary manner is of russet color but
spotty, and the color varies in shade. It has, therefore, hitherto been the practice
to give it a black color in order to get the same shade throughout.
My invention has for object to so treat such leather that it shall have a russet
color throughout its surface.
For this purpose I take care during the tanning process to keep the leather from
direct contact with the air, and directly the leather is removed from the tan pit
I dry the same in the open air whereby I find that as soon as the leather is
sufficiently dried its surface is practically of an even russet colour throughout
and is fit to be used either in this natural color or colored in any other shade
than black.

Improvements in the Treatment of Leather.
I, WILHELM HERMAN JEANSSON, of 28, Dovenfleet, Hamburg, in the Empire
of Germany, Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to the treatment of that kind of leather known as
"
"horse crup."
Horse crup leather after tanning in the ordinary manner is of russet color but
spotty, and the colour varies in shade. It has therefore hitherto been the practice
to give it a black color in order to get the same shade throughout.
My invention has for object to so treat such leather that it shall have a russet
color throughout its surface.
For this purpose I take care during the tanning process to keep the leather from
direct contact with the air and directly the leather is removed from the tan pit
I dry the same in the open air whereby I find that as soon as the leather is
sufficiently dried its surface is practically of an even russet color throughout and
is fit to be used either in this natural color or colored in any other shade than
black.
In some cases it may be found that leather treated as herein before described is
too hard for some purposes, and in such cases I dress the grain side of the leather

page_text: with a suitable oil or grease as much being applied as the leather can easily
imbibe. The surplus grease is removed from the grain surface by sponging with
benzine.
The flesh side of the leather is curried or levelled in the usual manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The described process for treating leather for the purpose specified.
2. Horse crup leather prepared substantially in the manner described for the
purpose specified.
