"
Sealed the 14th July 1854, and dated the 31st January 1854.
PROVISIONAL SPECIFICATION left by the said Louis Christian Koeffler
at the Office of the Commissioners of Patents, with his Petition, on the
31st January 1854.
I, LOUIS CHRISTIAN KOEFFLER, of Rochdale, in the County of Lancaster,
Bleacher and Dyer, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, DRESSING,
AND FINISHING YARNS OR THREADS," to be as follows:-
My improvements consist, first, in preparing and dressing yarn or thread in
the hank or skein, and by more efficiently laying the fibre of the same, render-
ing it capable of receiving a higher degree of polish or finish than has hitherto
been accomplished; and, secondly, in the mode of stretching and giving motion
to the yarn or thread, by which arrangement the said yarn or thread is more
equally formed, and any inclination to flatness or angularity efficiently pre-
vented. The yarn or thread, having been previously sized, stiffened, or pre-
pared, is passed under and over reciprocating or traversing rods or bars covered
with felt or any similar substance, over and round an exterior roller 'also
covered with a similar substance, then between a second roller (revolving in an

page_text: opposite direction to the yarn or thread) and a plate or table of brass, copper,
or other more suitable material, heated by steam, air, or any other means,
which partially dries and "irons" or smooths the surface of the said yarn or
thread; it then passes over and round a third and exterior roller, also covered.
with felt or any similar substance, and which revolves in bearings moving in
grooves or guides, so that by means of a screw or otherwise any amount of
tension may be given to the yarn or thread desired or requisite by increasing
the distance between the exterior rollers. These said rollers, besides their
rotary motion, which causes the yarn or thread to revolve, have at their ends a
lateral or diagonal reciprocating motion, which, in conjunction with the action
of the reciprocating rods, causes the yarn or thread to be continually altering
its position, thereby imparting to it the desired roundness of finish and polish.
The said reciprocating or transversing rods may be worked by or from cranks or
cams, and the lateral reciprocating motion given to the ends of the two exterior
rollers by similar means, either of which may be made to communicate the
required motions to the said rollers and rods.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said Louis Christian Koeffler in the Great Seal Patent Office on the
29th July 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
CHRISTIAN KOEFFLER, of Rochdale, in the County of Lancaster, Bleacher and
Dyer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of January, One thousand eight
hundred and fifty-four, in the seventeenth year of Her reign, did, for Her-
self, Her heirs and successors, give and grant unto me, the said Louis
Christian Koeffler, Her special license that I, the said Louis Christian
Koeffler, my executors, administrators, and assigns, or such others as I, the
said Louis Christian Koeffler, ny 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
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, DRESSING, AND
FINISHING YARNS OR THREADS," upon the condition (amongst others) that I,
the said Louis Christian Koeffler, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature of the

page_text: 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 I, the said Louis Christian Koeffler, do hereby
declare the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, and accompanying Drawing (that is to say):-
Fig. 1 is a side elevation of the machine I employ; and Fig. 2 is a vertical
section thereof. The framework of the machine is shewn at a, upon one side
of which is mounted, in an inclined slot, a roller b; a second similar roller i is
mounted in independent standards (one of which is shewn at c,) capable of
sliding upon guides carried by the framework a. The standards c, situate at
either side of the machine, are provided with nuts, within which are situate
screws, as at d, turning in bearings e, and furnished with bevil wheels f gearing
into others 9. the axis of which carries a winch handle h, by the turning whereof
the rollers and i, may be brought nearer to or farther from each other.
Between the rollers b, i, are a series of rods j, mounted on one side of the
machine in guides, and carried at the other by forks k extending from levers 7,
which are capable of vibrating upon a centre pin m.
The levers are provided
with vertical slots, within which are situate cranks formed upon a shaft n, which
in its revolution will therefore cause the said levers to vibrate and communicate
a reciprocating motion to the rods j. A chamber o, supplied with steam from
any convenient source, extends across the machine; its upper surface having a
concave portion corresponding to the periphery of a roller p, which is covered
with felt, flannel, or other such soft substance. The axis of this roller is
mounted in vertical slots, and is weighted by means of à rod q at either end
and loaded lever . The main driving shaft of the machine is shewn at 3,.
upon which there is a spur wheel t, taking into another u, upon the axis of
the roller b; the last-mentioned wheel communicates rotatory motion to the
central roller p by means of the train v, w, a; the crank shaft is driven
by the bevil wheels y, one of which is on the main shaft s.. The yarn
or thread having been sized, stiffened, or prepared by any of the substances
usually employed; is applied to the machine, and operated upon in the
following manner-The rollers b, i, are lifted from their slots; and the lever r
raised so as to admit of the roller p being also removed. The. hanks of
yarn or thread are then strung upon the rollers b, i, which are restored to their
position in the machine, and the central roller p again adapted, the material
lying between it and the steam chamber o. The rods j are removed from thei
supports and again applied so as to pass under and over the yarn, as shewn in

page_text: the Drawing. The required tension of the material being now effected by
turning the crank handle h, and rotatory motion being communicated to the
main shaft s, the roller will cause the material to be carried onward in the
direction of the arrow between the heated steam chest o and roller p, which
revolves in the contrary direction, by which means the yarn or thread will be
partially dried and smoothed, or ironed to the required finish or polish. During
this operation the revolution of the cranked shaft n will cause the bars j to
reciprocate in their guides, whereby the material will be continually altered in
its position, and a roundness and even polish imparted thereto. For the sake
of economy a number of hanks of material may be finished at the same time
side by side upon the rollers b, i, and in order to keep them distinct during the
operation I apply a series of division plates as at y, which serve also as sup-
ports for the rods j. The desired effect having been accomplished, the hanks
of yarn or thread are removed from the machine after the manner described in
explaining their adaptation. In reference to the roller p and steam chest I
would observe, that, if, desired, the former may be supplied with steam or other
heating medium, and the latter consists of a solid dish formed table covered
with flannel, felt, or other soft material, or heat from steam or other source may
be applied to both portions. I would also remark, that I sometimes impart to
the rollers b, i, a reciprocating motion in addition to that of the rods y, or in
lieu thereof.
0,
Having thus described and ascertained the nature of my said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that the points of novelty I claim as secured to me under the above in part
recited Letters Patent are,-
Firstly, passing the yarn or thread between two or more friction surfaces, the
one or both being heated by steam or by other means.
Secondly, imparting to the material a transverse motion by means of rods or
rollers in contact with which it passes.
And, thirdly, the general arrangement and combination of machinery above
described.
In witness whereof I, the said Louis Christian Koeffler, have hereunto
set
my hand and seal, the Twenty-eighth day of July, in the year of
our Lord One thousand eight hundred and fifty-four.
