PROVISIONAL SPECIFICATION left by the said Alexander Melville Clark at
the Office of the Commissioners of Patents on the 29th June 1876.

"AN IMPROVED WATERPROOFING COMPOUND FOR SKINS AND
LEATHER.'
"
This Invention relates to an improved composition for waterproofing skins and
leather of all kinds, whether natural or artificial.
The following are the ingredients of the composition, and the mode of preparing
the same:
Olibanum (resin)
Axunge, tallow or mutton fat 400 parts
-
450
,,
-
100
"
300
""
10
Beeswax
Linseed or other oil
Essence of aspic
The above proportions may however be varied. The axunge, tallow or mutton
fat, is first melted by preference in a water bath, and then the olibanum in powder
or lumps is dissolved therein, after which are added the beeswax and linseed or
other oil, and, lastly, the essence of aspic or other perfume used to scent the com-
position. The mixture is well stirred and-afterwards drawn off into vessels, or
allowed to cool and put up into tins or pots for sale. The axunge in the above
composition serves as a solvent and possesses the property of retaining the gummy
or resinous matters in a pasty condition. The olibanum forms the principal
ingredient in the composition, rendering as it does the leather impervious to moisture.
The wax serves as an agglutinative material, while the linseed or other oil binds
the whole mass together, and renders it more homogeneous and dilutes it to the
consistency desired.
This improved waterproofing composition is sold for use in an unctuous condition,
and is more particularly efficacious when applied on a new boot or shoe, although
I Price 4d1

page_text: it may also be applied with advantage on old leather, as also to natural or artificial
shoe, harness, or other leather before it is worked up into the manufactured article.
The composition only requires to be applied around the boot, between the sole and
the upper, and for a depth of about half an inch around the latter. The com-
position may be put on with the finger, or with a brush, or otherwise. The boot
is slightly warmed before applying the composition, and again afterwards to cause
it to penetrate the leather, and the operation may be repeated if necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Alexander Melville Clark in the Great Seal Patent Office on the 27th
December 1876.

To the above ingredients may also be added 50 parts of colophony or galipot, in
which case the composition would consist of the following:-
Olibanum
This improved waterproofing composition is sold for use in an unctuous condition,
and is more particularly efficacious when applied on a new boot or shoe, although
it may also be applied with advantage on old leather, as also to natural or artificial
shoe, harness, or other leather before it is worked up into the manufactured article.
The composition only requires to be applied upon the sole, around the boot, between
the sole and the upper, and for a depth of about half an inch around the latter.
The composition may be put on with the finger, or with a brush, or otherwise. The

page_text: boot is slightly warmed before applying the composition, and again afterwards to
cause it to penetrate the leather, and the operation may be repeated if necessary.
The composition may be rendered more or less fluid, and prepared either over an
open fire, or in a water bath, or by means of steam. The essence of aspic serving
to scent the composition may also be replaced by any other perfume.
Having described the nature of the said Invention, and the manner of performing
the same, I would observe that I do not limit myself to the exact proportions of the
ingredients herein-mentioned, but that what I claim as the Invention to be protected
by the herein-before in part recited Letters Patent is, the waterproof composition
or compositions for hides, skins, shoe, harness, and other leather, substantially as
herein specified.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Twenty-seventh day of December, in the year of
our Lord One thousand eight hundred and seventy-six.
