Year: 1856

page_text: LETTERS PATENT to Lazare Ochs, of Saint Josseten Noode, in the
Kingdom of Belgium, Manufacturer, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF CERTAIN KINDS OF PAPER PROM THE REFUSE
OF TANNED LEATHER."-A communication.
COMPLETE SPECIFICATION filed by the said Lazare Ochs at the Office
of the Commissioners of Patents, with his Petition and Declaration,
on the 19th March 1856, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LAZARE
OCHS, of Saint Josseten Noode, in the Kingdom of Belgium, Manufacturer,,
send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN.
THE MANUFACTURE OF CERTAIN KINDS OF PAPER FROM THE REFUSE OF TANNED
LEATHER," and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same, and have
made solemn declaration that I received the said Invention by communication
from a foreigner residing abroad:

page_text: NOW KNOW YE, that I, the said Lazare Ochs, do hereby declare that
the following complete Specification, under my hand and seal, fully describes
and ascertains the nature of the said Invention; and the manner in which
the same is to be performed.
The object of this Invention is to preserve the cuttings and other waste of
leather after the hides or skins shall have been submitted to the usual process
of tanning, and to treat such refuse or waste in such manner as to render it
eligible to be used in the manufacture of coarse packing paper. In order to
render such waste fit for the aforesaid purpose it is necessary to extract the
"tanning" therefrom, and this is effected by passing the pieces of waste or
refuse through a cylindrical sieve or riddle, the meshes or openings in which
are a quarter of an inch apart. On a strong wooden frame is fixed an iron
rod of sufficient strength to support the cylinder; the ends of the rod rest on
bearers on the apex of the framing, and passing over beyond these bearers
form axles. Motion is transmitted to the whole apparatus by means of a
driving band and shaft, water being poured on to or into the cylinder, its
revolutions will have the effect of entirely freeing the waste from the tanning.
Or, when the waste is so wet as to render the foregoing process ineffectual or
too tedious, it may be placed in open work baskets and (being saturated with
water) continually shaken about until the desired separation ensues and the
substance is fit for use. After the waste or refusedlias undergone the one or
the other of the above operations, I cut up old rope or cord into pieces,
picking or treating it in-such-wise that--the-fibres of which such rope is
composed shall be uncoiled or seperated, and I mix about twenty per cent. of
the fibre so obtained with the waste or refuse of hides. and skins, treated, as,
aforesaid, and placing, the whole in a mortar or other suitable vessel, beat the
mass into a pulp;, from which paper, may be made in the usual manner.
Other textile or fibrous material may be used with, the. cuttings or waste of
tanned skins or hides. I have mentioned old rope or twine cuttings, in prefer-
ence, because they are found to answer the purpose very well. Or a very
coarse paper is made of the waste- leather without the admixture of fibrous
textile, or vegetable matter, but the quality is found to be very inferior to the
combination herein described:
Having now described the nature of the Invention communicated to me,
and the manner or process by which it is carried into effect, I would observe
that I do not confine myself to the exact proportions of twenty parts in
one hundred in the admixture of rope, fibre, or other fibrous material, as such
proportions may be varied according to the quality or nature of the material

page_text: to be mixed with the waste; but I claim the exclusive use of the combination
of waste or refuse leather after tanning, treated in the manner herein-before
described.
In witness whereof, I, the said Lazare Ochs, have hereunto affixed my
hand and seal, this Seventeenth day of March, in the year of our Lord
One thousand eight hundred and fifty-six.
Witness,
H. BIEBUYCK,
Brussels.
