PROVISIONAL SPECIFICATION.
A New Ornamental Leather, and Process for Preparing the same.
We, THOMAS JOHN WILLIAM MACKENZIE of Coppin Street, Richmond, in the
Colony of Victoria, Leather Salesman, and WILLIAM JOHN NODIN of Burnley
Street, Richmond, in the said Colony of Victoria, Tanner, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a new ornamental leather and the means of preparing or
manufacturing the same and consists, in the first place, in taking that portion of the
entrails of a sheep, bullock, cow or other animal known as the paunch, and treating
the same in the following manner :-The paunch is cleansed and skinned and the
mucous membrane is then "limed or soaked in a lime vat or tub for one or two
days, more or less, depending on the strength of the liquid. It is then taken out
and "bated" or softened by the ordinary tanner's process.
"
It is then tanned in a mixture of, say, schumac and water or wattle bark or other
suitable tanning solution. When sufficiently tanned, the skin is removed and
stretched out to dry.
The surface of that portion of the skin known as the "honeycomb" presents a
beautifully veined or webbed surface, while other portions present a furry surface,
and other portions again a comparatively smooth surface. When so prepared and
tanned the leather will be found very ornamental, workable, and of great strength.
Dated this 6th day of November 1893.

COMPLETE SPECIFICATION.
A New Ornamental Leather, and Process for Preparing the same.
We, THOMAS JOHN WILLIAM MACKENZIE, of Coppin Street, Richmond, in the
Colony of Victoria; Leather Salesman, and WILLIAM JOHN NODIN, of Burnley
Street, Richmond, in the said Colony of Victoria, Tanner, 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 a new ornamental leather and the means of preparing or
manufacturing this from that portion of the entrails of a sheep, bullock, cow or
other animal, known as the paunch, by treating it in the following manner.
The paunch is cleansed and the outer skin is removed leaving the inner mucous
membrane which is then "limed" (or soaked in a liquor consisting of about 1 lb. of
lime to a gallon of water) for several days. The limed membrane is then taken out
and "bated or softened by the ordinary tanner's process, as for instance by soaking
it for about 2 days in a bath consisting of about 2 lbs. bran to a gallon of water.
"
The bated membrane is then tanned iu a liquor of schumac, wattle bark or other
suitable tanning solution. When sufficiently tanned, the membrane is stretched out
on boards to dry, and when dried is trimmed and brushed.
The surface of that portion of the membrane known as the "honeycomb "presents
a beautifully veined or webbed surface, some other portions present a furry surface,
and other portions a comparatively smooth surface. The leather thus prepared,
which may be coloured as desired, is very ornamental, workable and of great
strength.
