VADS"
Sealed the 29th October 1867, and dated the 2nd May 1867.
PROVISIONAL SPECIFICATION left by the said Gustavus Adolphus John
Schott and John Siegmund Rosenthal at the Office of the Commissioners
of Patents, with their Petition, on the 2nd May 1867.
We, GUSTAVUS ADOLPHUS JOHN SCHOTT and JOHN SIEGMUND ROSENTHAL;
both of Bradford, in the County of York, Woollen Spinners; do hereby declare
the nature of the said Invention for "AN IMPROVED SPECIES OF YARN," to be
as follows:-
The object of our Invention is to produce not what may be called a mottled
yarn but an interfolded or intermingled yarn. We mean by this that the
result of our improved yarn is as follows:-Our yarn consists in introducing
into slubbings, rovings, or yarns, whether the same be single; two, or more
fold, one or more additional slubbings, rovings, or yarns; such additional slub-
bings, rovings, or yarns by the variation of speed causing the result which we
attain, viz., the production on the yarn produced of what may be termed an
irregular effect, viz., the production of a species of variegated yarn.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GUSTAVUS
ADOLPHUS JOHN SCHOTT and JOHN SIEGMUND ROSENTHAL, both of Bradford, in
the County of York, Woollen Spinners, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of May, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Gustavus Adolphus John Schott and John Siegmund Rosenthal, Her special
licence that we, the said Gustavus Adolphus John Schott and John Siegmund
Rosenthal, our executors, administrators, and assigns, or such others as we,
the said Gustavus Adolphus John Schott and John Siegmund Rosenthal, our
executors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "AN IMPROVED SPECIES OF YARN," upon the.
condition (amongst others) that we, the said Gustavus Adolphus John Schott
and John Siegmund Rosenthal, our executors or administrators, by an instru-
ment in writing under our or their hands and seals, or under the hand and
seal of one of us or them, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Gustavus Adolphus John Schott and
John Siegmund Rosenthal, do hereby declare the nature of the said Inven
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof, that is
to say :-
The object of our Invention is to produce not what may be called a mottled
yarn but an interfolded or intermingled yarn. We mean by this that the
result of our improved yarn is as follows:-Our yarn consists in introducing
into slubbings, rovings, or yarns, whether the same be single, two, or more
fold, one or more additional slubbings, rovings, or yarns, such additional

page_text: slubbings, rovings, or yarns (by the variation of speed in the twisting or
spinning machinery on which they are produced) causing the result which
we attain, viz., the production on the yarn of what may be termed an
irregular effect, viz., the production of a species of variegated yarn. The
yarn in question may be more particularly defined as one presenting the
intermittently, interfolded, or intermingled appearance at given intervals in
contradistinction to an ordinary twisted yarn, the effect being the irregu-
larity (recurring regularly or irregularly as desired) alluded to, and the result
being that when such yarn, either as warp or weft, or both in conjunction, is
woven into a piece of fabric a novel result is arrived at hitherto unknown.
We therefore wish it to be understood that what we claim is, the result
previously alluded to, viz., yarns, slubbings, or rovings single or more fold, as
before described, interfolded only at given intervals, the spaces between such
interfolds presenting only the ground or continuous yarn, slubbing, or roving.
In witness whereof, we, the said Gustavus Adolphus John Schott and
John Siegmund Rosenthal, have hereunto set our hands and seals,
this Twenty-eighth day of October, in the year of our Lord One
thousand eight hundred and sixty-seven.
GUSTAVUS ADOLPHUS JOHN SCHOTT. (L.S.)
JOHN SIEGMUND ROSENTHAL.
