IMPROVEMENTS IN MACHINERY FOR SPINNING CARDED WOOL
Year: 1875

page_text: LETTERS PATENT to Oscar Schimmel, of Chemnitz, Saxony, Machine
Maker, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
SPINNING CARDED WOOL."
Sealed the 3rd March 1876, and dated the 11th September 1875.
PROVISIONAL SPECIFICATION left by the said Oscar Schimmel at the
Office of the Commissioners of Patents, with his Petition, on the
11th September 1875.
I; OSCAR SCHIMMEL, of Chemnitz, Saxony, Machine Maker, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR SPINNING CARDED WOOL," to be as follows:-
This Invention consists of an improved arrangement or construction
of spinning frame for spinning carded wool, by means of which the
yarns are drawn out a considerable length, and have communicated to
them a peculiar twist, which renders the threads more even and uniform
than heretofore.
The novelty of this Invention consists in a novel construction of
twisting apparatus or mechanism composed of a peculiarly shaped cover,

page_text: which is laid on a circular bracket attached to the frame of the machine.
The cover is pierced with a hole in its uppermost part to admit of the
passage of the sliver or unspun thread: The cover contains bearings, in
which revolve on a horizontal axis two corrugated or serrated cylinders
or drawing rollers.
The motion is communicated to the drawing rollers by means of bevil
gearing, part of which is keyed on the axles of the fluted drawing rollers,
and part on a cap supported by the circular bracket which supports_the_
cover. Both the cover and cap are fitted with V wheels or pulleys,
which are worked by bands from any convenient portion of the machine.
The fluted drawing rollers have therefore a rotary motion on their own
axes, and a horizontal motion communicated to them, which has the
effect of drawing down the sliver from the bobbin, and at the same time
giving it a twist before passing it on to the spindle to be converted into
a finished yarn.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Oscar Schimmel in the Great Seal Patent Office
on the 11th March 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, OSCAR
SCHIMMEL, of Chemnitz, Saxony, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her, reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Oscar Schimmel, Her
special license that I, the said Oscar Schimmel, my executors,
administrators, and assigns, or such others as I, the said Oscar
Shimmel, my executors, administrators, and assigns, should at any time
agree-with-and-no-others,-from-time-to-time-and-at-all-times-there-
after-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 Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR SPINNING CARDED WOOL,” upon
the_condition (amongst others). that I, the said Oscar Schimmel, my
executors or administrators, by an instrument in writing under my, or

page_text: their, or one of their hands and seals, 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 I, the said Oscar Schimmel, 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, reference being bad to the Drawing hereunto
annexed and to the letters and figures marked thereon (that is to
say) :-
This Invention relates to an improvement in spinning machinery,
whereby the drawing of the roving or sliver and the spinning or twisting
of the same is effected by one and the same pair of rollers, which then
pass it to the ordinary flyer to equalize the twist, and finish the thread
or yarn.
In the accompanying Drawing I have shown at Fig. 1 in sectional
elevation so much of a spinning frame as will serve to illustrate my
Invention.
A is the spool or bobbin of roving or sliver to be drawn and twisted,
supported in slotted guides, and bearing upon a driven roller B. Tho
sliver or roving a is led through a fixed guide b, and thence between a
pair of feed rolls C, which deliver the sliver or roving to a pair of
drawing and twisting rollers D. These rollers are mounted in a cap
5 picco E, which is supported on a rebated annular bracket piece F, and
is free to rotate thereon. A central trumpet-mouth shaped opening is
made in this cap piece E to allow of the passage of the sliver or roving
to the rollers D.
Immediately below the rollers and concentric with the bracket F and
30 the cap piece E is a flanged collar G, which is supported by a flange on
the inner side of the bracket. Both the cap picce E and the collar G
are furnished with a band pulley e, g, and round thesc pulleys pass
respectively the bands e and g', which receive motion from their
respective drums E' and G'. The relative speeds of these drums may be
25 varied to suit the work in hand by the use of change gearing, as is well

page_text: The drawing rollers D, which are shewn in plan view at Fig. 2, and in
cross section at Fig. 3, are fluted to ensure a good bite of the sliver or
roving, and thus turn freely on stud axles carried by the cap piece. On
a hub of one of the rollers D is keyed a bevil wheel d, which gears into
a pinion & formed on or attached to the collar G for the purpose of t
receiving rotation therefrom, and the pressure of a spring carried by the
cap piece ensures the maintenance of frictional contact between the
rollers. When therefore rotary motion-is-imparted-to-the-collar-G-the-
rollers D will be caused to 'turn on their axes, and draw down the roving
from the feed rolls. While this operation is taking place rotary motion 1
will also be imparted to the cap piece E, and the result of this will be
the turning of the rollers D in a horizontal plane, and the consequent
twisting of the roving as it passes into the nip of the rollers. As the
twisted roving or thread leaves the rollers D it is led down to the flyer H
of the spindle I, which will equalize the twist, and finish the thread, 1
laying it upon the bobbin K.
The mode of driving the spindle and flyer is indicated in the Drawing,
but the means for working the copping rail, the adjustment of the
tension on the bobbin, and the adjustment of the speed of the flyer.
relatively to that of the twisting rollers need no explanation, as such 2
matters will be well understood by any competent spinner.
Having now set forth the nature of my Invention of " Improvements
in Machinery for Spinning Carded Wool," and explained the manner of
carrying the same into effect, I wish it to be understood that under the
above in part recited Letters Patent I claim, the arrangement of 2
mechanism above described for effecting the drawing and twisting or
spinning of slivers of wool by means of one pair of drawing rollers.
In witness whercof, I,_the_said_Oscar Schimmel, have hereunto
__set_my_hand-and-seal,-the-Eighth day of March, in the year
