page_text: LETTERS PATENT to Joseph Julius Sachs, of Barrow in Furness, in the County
of Lancaster, for the Invention of "IMPROVEMENTS IN THE EXTRACTION OF
FATTY MATTERS FROM SUBSTANCES OR MATERIALS CONTAINING SUCH FATTY,
OILY, OR GREASY MATTERS."
Sealed the 11th July 1879, and dated the 29th April 1879.
PROVISIONAL SPECIFICATION left by the said Joseph Julius Sachs at the
Office of the Commissioners of Patents on the 29th April 1879.
JOSEPH JULIUS SACHS, of Barrow in Furness, in the County of Lancaster.
IMPROVEMENTS IN THE EXTRACTION OF FATTY MATTERS FROM SUBSTANCES OR
MATERIALS CONTAINING SUCH FATTY, OILY, OR GREASY MATTERS."
My Invention is applicable in the treatment of wool, cotton, flax, hemp, jute,
silk, and other fibrous materials, and of the yarns and fabrics manufactured from
such fibrous materials, and generally in the treatment of oily waste, and of any
materials or substances imbued with or holding or containing natural or acquired
fatty, greasy, or oleaginous matters. I treat the said materials or substances with
solutions of silicate of soda or of silicate of potash or with other silicate solutions.
The said materials or substances are steeped in the solution selected until the fatty
or oleaginous matter is sufficiently extracted, the solution being used either cold,
warm, or heated.
The materials or substances may or may not be agitated in the
solution to expedite the process, and any suitable manipulation of the said materials
or substances may be adopted. By the employment of the said solutions in the
treatment, say, for example, of fibrous or textile materials or fabrics, I am enabled
to remove or extract the fatty or oleaginous matters without injuring to any great
extent the fibres of the said materials or fabrics. Oily waste, when subjected at
intervals to my improved treatment, may be used over and over again, being
adapted to re-absorb fatty or oleaginous matters after the said treatment.

My said Invention is applicable in the treatment of wool, cotton, flax, hemp, jute,

page_text: fatty, greasy, or oleaginous matters. I treat the said materials or substances with
solutions of silicate of soda or of silicate of potash, or with other silicate solutions.
The said materials or substances are steeped in the solution selected until the fatty
or oleaginous matters are sufficiently extracted, the solution being used either cold,
warm, or heated. The materials or substances may or may not be agitated in the
solution to expedite the process, and any suitable manipulation of the said
materials or substances may be adopted. In cases where it is not considered
necessary to agitate the materials and solutions I prefer to employ a vat or recep-
tacle, into the lower part of which the materials to be treated are placed. A per-
forated division, diaphragm, or grid is then placed over the materials in the vat,
and the solution is then added. By employing the said open diaphragm the
materials are prevented from rising in the vat, while the fatty matter extracted
from them by the action of the solution floats upon the surface of the liquid and
above the level of the diaphragm or division, so that it can easily be skimmed off
and removed. Where the solutions are used in a heated state it is preferable to
allow the oleaginous scum to cool before removal.
Another form of apparatus may be employed to promote agitation of the
materials and solutions, and to this end I place a perforated drum or wirework
cage within a large receptacle containing the solutions. This drum is divided into
any suitable number of compartments by perforated divisions, and into certain of
those compartments, preferably into every second compartment, I place the material
which it is desired to cleanse. The drum is arranged to revolve either horizontally
or vertically within the larger vessel, and either wholly or partially submerged in
the solution contained therein. By this means the solution is brought into more
intimate contact with the greasy materials, and their cloansing is more thoroughly
effected. The resulting supernatant oleaginous scum is removed as hereinbefore
referred to. After the materials have parted with their fatty matters the spent
solution may be drawn off and a further purifying effected by the addition of
water, acids, or other cleansing agents; and when these have performed their duty
they may in their turn be run off and the cage allowed to revolve in the atmosphere
at a high speed, so as to dry the materials contained in the compartments. Steam or
a current of hot or cold air may be employed to assist in the drying operation. By
the employment of the herein before described solutions with apparatus the same or
similar to the forms already indicated in the treatment of fibrous or textile
materials or fabrics I am enabled to remove or extract the fatty or oleaginous
matters without injuring to any great extent the fibres of the said materials or
fabrics. Oily waste when subjected at intervals to my improved treatment may be
used over and over again, being adapted to re-absorb fatty or oleaginous matters
after the said treatment.
Having now described my said Invention, and indicated methods whereby the
same may be carried inte practical effect, I desire to state in conclusion that what
I consider to be novel and original, and therefore claim as the Invention secured to
me is as follows:-
-
Treating yarns and fibrous materials and fabrics which have become impregnated
with fatty or oleaginous matters with silicate solutions, so as to cleanse and render
them again fit for use, substantially by the means, apparatus, and in the manner
herein before described and set forth.
In witness whereof, I, the said Joseph Julius Sachs, have hereunto set my
hand and seal, this Twentieth day of October, in the year of our Lord
JOSEPH JULIUS SACHS. (L.S.)
