PROVISIONAL SPECIFICATION.
Improvements in Extracts Applicable for Use in Fermenting and in
the Preparation of Leather.
I, MORRIS PAUL HATSCHEK of 48 St. Georges Road S.W. in the County of
Middlesex, Chemical Engineer do hereby declare the nature of said invention for
"IMPROVEMENTS IN EXTRACTS APPLICABLE FOR USE IN FERMENTING AND IN THE
PREPARATION OF LEATHER."
This Invention is an improvement or addition to my patent No. 3363 Dated
5th of March, 1888, to be as follows:-
My invention refers to my description of patent on "An improved extract. for
use as a ferment and as a food preparation" delivered under No. 3363 on the
5th March 1888 and constitutes a further improvement of the same and the
application of the extracts mentioned there and for other similar preparations.
I have found out since that the extract which forms the subject of the quoted
description there called "Malto Peptine" can be used for replacing yolks of eggs,
animal brains, milk bran, and other substances containing animal or vegetable
albuminous matter for fermenting or stuming, kips-skins and hides and for dressing
them and producing soft pliable and durable leather of any description, such as
for belts or machine straps for upper leather of boots or shoes, for gloves of all
kinds, &c.
•
My improved extract will fill up the tissues formed in the skins by the previous
processes of liming fermenting (in bate puro or otherwise) and treating with salt and
alum and will when used instead of yolks or other substances (containing albuminous
matter) produce the same or very similar and frequently better results.
Instead of the combinations of acids mentioned in my description dated 5th March
1888 there can be used a larger proportion of sulphureous or another antiseptic acid
alone for imperfect peptonisation and this latter can if required be completed later on
by subsequent fermentation.
The peptonising of the raw material I usc, can be also accomplished partly or
entirely by employing the juice or the tissue of the Agave (American Aloc) or by
other vegetablo substances forming part of or being extracted from so called
peptonising or flesh consuining plants.
Although the meat peptone used at present for feeding and pharmaceutical purposes
would be in most cases too expensive or unfit for replacing my Malto peptone, still I
claim the sole right of using such meat-peptones for fermenting purposes (in
Breweries, Distilleries, Tanneries &c.) and for treating with them, leather of any
kind instead of applying my vegetable extracts (Malto peptine) for the said purposes.

ני
I have found out since that the extract which förins the subject of the quoted
description there called "Malto Peptine can be used for replacing yolks of eggs
animal brains milk bran and other substances containing animal or vegetable
albuminous matter for stunning (fermenting) kips skins and hides and for dressing
them and producing soft pliable and durable leather of any description such as
for belts or machine straps for upper leather of boots or shoes for gloves of all
kinds &c.
My improved extract will fill up the small pores or fissures formed in the skins by
the previous processes of liming fermenting (in bate pure or otherwise) and for
heating with salt and alum and will when used instead of yolks or other substances
(containing albuminous matter) produce the same or very similar and frequently
better results.
The malto peptine to be employed as Leather food or dressing can be mixed also
with an addition of oil (olive neatsfoot fishoil &c.) as used in the manufacture of
Leather and to bring the liquor into the proper state of emulsion about one per cent.
of a strong solution of Borax or soda or about five per cent. of Stearic Acid can bo
well soused with the oil to be added beforehand or with the whole mixture afterwards
for the feeding or dressing of skins to be made into very soft and pliable leather
an addition of about ten per cent. of Glycerine can be used with the leather food.
Instead of the combination of acids mentioned in my description dated 5th March
1888 there can be used a larger proportion of sulphureous or another antiseptic acid
alone for imperfect peptonisation and this latter can if required be completed later on
by subsequent fermentation.
The peptonising of the raw material I use can be also accomplished partly or
entirely by using the juice or the tissue of the Agave (American aloe) or by other
vegetable substances forming part of or being extracted from so called peptonising or
flesh consuming plants.
Although the meat peptones used at present for feeding and Pharmaceutical
purposes would be in most cases be too expensive or unfit for replacing my Malto
peptine still I claim the sole right of using such meat peptones for fermenting
purposes (in breweries distilleries tanneries &c.) and for treating with them leather
of any kind instead of applying my vegetable extracts (malto peptine) for the said
purposes.
Having now described and ascertained the nature of my invention and the
manner in which the samo is or may be performed, I declare that what I claim
is the-
"Improvements in extracts applicable for use in fermenting and in the preparation
of leather as hereinbefore described.
