page_text: I THOMAS NATHANIEL ASHMAN, of 9, Grove Park, in the city of Bristol, Tanner
and Currier, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of an improved composition to be
applied to leather as hereinafter described for the purpose of rendering it more
waterproof and durable than by the processes hitherto in use.
In manufacturing my improved composition, I take :-Asphalte melted with
cod-oil or any other fish, animal or vegetable oil, bees-wax, sperinaceti-wax or
other wax,-litharge and linseed oil well boiled-terebene or any other dryers,
Venice turpentine, ground mica or asbestos mixed with gum dammar dissolved-in
alcohol, patent dryers or dry white lead, gutta percha and india-rubber dissolved
in any usual solvent, the whole being thoroughly mixed and combined by heat.
The proportions of the above ingredients will vary according to the manner in
which the leather to be treated has been tanned but I find that for what is known
as a medium tanned leather, about equal proportions of the above ingredients by
weight give good results.
In order to apply my improved composition, the leather when it is to be.
treated on both sides is simply immersed in the heated composition until the
leather has become thoroughly impregnated with the composition, but when the
leather or article is to be treated on one side only, the leather or article is
preferably beated by suitable means such as by a hot plate heated by steam or hot.
water or by any other suitable device to a temperature say from 100 to 140 degrees
Fahrenheit, according to the tannage, or kind of leather, care being taken not to
burn, injure, or scald the leather or article; the composition is then, applied by
means of a brush or otherwise on, the side of the leather opposite to that to which
the heat is applied the coating being carried on until the leather has become
sufficiently impregnated.
In some cases such as for example when treating boots and shoes the composition,
is applied on the surface of the leather to which the heat is applied.

I THOMAS NATHANIEL ASHMAN of 9 Grove Park, in the city of Bristol, Tanner
and Currier, 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 manufacture of an improved composition to be

waterproof and durable than by the processes hitherto in use.

In manufacturing my improved composition I take--Asphalte melted with cod-
oil or any other fish, animal or vegetable oil, bees-wax, spermaceti-wax, or other
wax, litharge and linseed oil well boiled, terebene or any other dryers, Venice
turpentine, ground mica or asbestos mixed with gum dammar dissolved in alcohol,
patent dryers or dry white lead, gutta percha, or india-rubber dissolved in any of
the usual solvents, the whole being thoroughly mixed and combined by heat..
The proportions of the above ingredients will vary according to the manner in
which the leather to be treated has been tanned but I find that for what is known
as a medium tanned leather, about equal proportions of the above ingredients give
good results.
In order to apply my improved composition, the leather when it is to be treated
on both sides is simply immersed in the composition until the leather has become
thoroughly impregnated with the composition, but when the leather or article is to
be treated on one side only, the leather or article is preferably heated by suitable
means such as by a hot plate heated by steam or hot water or by any other
suitable device (to a temperature say from 100 to 140 degrees. Fahrenheit)
according to the tannage or kind of leather, care being taken not to burn, injure
or scald the leather or article; or the composition can be applied by means of a
brush or otherwise on the side of the leather opposite that to which the heat is
applied the coating being carried on until the leather has become sufficiently
impregnated..
In some cases, such as for example when treating boots and shoes, the composition
is conveniently applied on that surface of the leather to which the heat is
applied.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The manufacture and use of the improved composition for treating leather and
leather articles as herein before described.
