IMPROVEMENTS IN THE MANUFACTURE OF. LACED FUR SKINS
Year: 1877

page_text: LETTERS PATENT to, Friedrich Erler, of Leipzig, Saxony, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF. LACED FUR SKINS."
Sealed the 29th April 1878, and dated the 31st October 1877.
PROVISIONAL SPECIFICATION left by the said Friedrich Erler at the Office
of the Commissioners of Patents on the 31st October 1877.

FRIEDRICH ERLER, of Leipzig, Saxony. "IMPROVEMENTS IN THE MANUFACTURE
OF LACED FUR SKINS."
The principal hair on the lower part of the backs of all species of foxes or bears,
or on the tails of most quadrupeds with skins, is very tight, and appears like felt.
The bending with galloons to give an elegant appearance to peltry has been in use
for a long time, and ensures solidity of the hairs, with reduction of price, by econo-
mizing the materials in manufacturing dear furs, such of black or grey foxes.
The ordinary mode of manufacture is to cut up the well spread skin in 3 to 10
millim. stripes (galloons). By observing the badge, colour, and fuming of the hairs
these galloons are distributed in such a manner as the object being manufactured
demands. They are then re-united by sewing up bands corresponding to the
galloons. This sewing occupies much time, and can only be done by experienced
seamstresses, who cannot always be obtained except at high rates of pay, which in
the manufacture of cheap fur skins is more expensive than the material.
My Invention has for its object the dispensing with this sewing, and consists in
fastening the galloons or leather strips on stuff by a gluten carefully prepared by a
solution of caoutchouc, whereby a a combination of the leather and stuff is obtained,
entirely solid and resistant to all influences of temperature, acids, and alkalies. By
pouring refined benzoine upon the best refined and pounded caoutchouc in luted
fictiles or steens, the use of the benzoine soon loosens the caoutchouc completely,
when the stuff is prepared as follows:-On a plain table, sufficiently large, and
made of strong wood with the smallest amount of pores, such as maple, the stuff is
first spread, and the loosened caoutchouc is then laid on by a tight pencil as equally
as possible, and further distributed more uniformly by a roller, lightly rolled over

page_text: it. The benzoine being volatile the stuff soon dries, after which the coat is renewed
4 to 5 times. The skins or their parts being first well spread or drawn out will be
coated on their leather sides in exactly the same manner, but in this case two or
three coats are sufficient, because the leather does not absorb the loosened caoutchouc
so much as the stuff. The temperature of the room wherein the work is performed
must not exceed 15° Reaumur, otherwise the benzoine is too quickly volatilized, and
an equal coating thereby rendered difficult.
After
It is to be observed that the stuff and leather must never be laid together .or
stratified on their coated sides during the coating operation, because they soon stick
together so closely that they cannot be separated even if apparently dry.
every coat the benzoine having been volatilized a pellicle of clear caoutchouc remains
on the stuff and leather. These different pellicles join themselves one to another
both in the stuff and leather, so as to be absolutely piecelesslike.
For fastening the galloons on to the stuff after being cut from the skins, or its
parts, and assorted, each of them must be spread over once more with the caoutchouc,
very thin, and loosened by benzoine by means of a tender pencil. When this coat
is about half dried the galloon is laid on the stuff in proper corresponding distance,
and pressed by a small roller.
When the benzoine is entirely volatilized the combination is insoluble, and this
with the solidity produced by the process allows the act of giving the last dye to
the naturally gallooned objects, as well as the use of etching-lie of soda to remove
the grease from them, and of acid colours to dye them.
..
The cost of manufacture by my Invention is reduced by 30% compared with the
ordinary process.

"IMPROVEMENTS IN THE MANUFACTURE

Having now described and particularly ascertained the nature of my said Invention,
and the manner in which the same may be used or carried into effect, I would -
observe in conclusion that what I consider novel and original, and therefore claim

page_text: as the Invention secured to me by the herein-before in part recited Letters Patent
is, joining the leather to stuff in laced fur skins by means of loosened caoutchouc,
substantially as herein-before described.
In witness whereof, I, the said Friedrich Erler, have hereunto set my hand
and seal, this Tenth day of April, in the year of our Lord One .thousand
eight hundred and seventy-eight.
