WILLIAM EDWARD GEDGE, of No. 11 Wellington Street, Strand, London, in the
County of Middlesex, Patent Agent, "A NEW OR IMPROVED COMPOSITION FOR
PRESERVING LEATHER, ARTICLES MADE OF LEATHER AND FOR OTHER APPLICATIONS
A communication to me from abroad by Jean, Marie, Louis, François, Granger, of
Paris, France.
This Invention relates to a novel compound comprising in its composition various
products, some of which may perhaps have been employed together, or separately,
for various purposes, but the known compounds, whether patented or not, have
not been endowed with the properties ensuring the preservation of leather and of
articles made of leather in the same degree as the compound the subject of this
Invention which in fact, by the union of the matters which I am about to
enumerate and some of which have never been utilized for this purpose, is endowed
with superior qualities which render it a novel and therefore a patentable product.
To make 100 Kilogrammes of this improved preservative compound, take of:-
Pure mutton tallow
Pure resin
Virgin wax (wax from the comb of young bees)
Fragrant oil of birch bark
Extract of Tannin from the chestnut tree
Kilos
13,050
43,500
3,480
13,900
-
13,900
Spent oil from chamois leather ("Dégras, pur moellon ")
Fish Oil (cod)
6,100
-
2,600
Spermaceti
Tannin extracted from the Acacia (quantity optional).
Lead nitrate or litharge
-
0,870
2,600

page_text: This composition may be modified either as regards the proportional quantity of
each article, or by the elimination of some of them, accordingly as the compound
is to be used for leather or hides, or for articles of leather, or for greasing horses'
hoofs.
I would however have it understood that one of the main elements is the use of
the tannic acid which I deem the most efficacious, forming the basis of this new
compound.
I may also substitute in lieu of the extract of chestnut wood or of the bark of
the acacia, extract of ordinary oak bark, or of white, grey, or evergreen oak.

A communication to me from abroad by Jean Marie Louis François Granger, of
Paris, France,
This invention relates to a novel compound comprising in its composition various

This composition may be modified either as regards the proportional quantity of
each article, or by the elimination of some of them accordingly as the compound
is to be used for leather or hides, or for articles of leather or for greasing horse's
hoofs.
I may also substitute for the Extract from the wood of the Chestnut tree, or
from the bark of the acacia, extract from ordinary oak bark, that of the white, the
grey, or the evergreen oak.
Having now described and ascertained the nature of the Invention communicated
to me as aforesaid and in what manner the same is or may be performed
I Claim as secured to me by the hereinbefore in part recited Letters Patent :—
The use of the new or improved composition hereinbefore described for preserving
leather, articles made of leather and for other applications; but I desire it to be
well understood that one of the principal elements in this composition, and that
which I particularly claim, is the use of Tannic Acid, which I deem the most

page_text: efficacious product forming the basis of this new compound or coating, and I
therefore claim its excluse use in the manufacture of " dégras" and any other
products intended for the preservation of leather.
In Witness whereof I the said William Edward Gedge have hereunto set
my hand and seal this Fifteenth day of November in the year of Our Lord
