PROVISIONAL SPECIFICATION left by the said Lorentz Albert Groth at
the Office of the Commissioners of Patents on the 20th May 1882.
LORENTZ ALBERT GROTH K.G.V Civil Engineer and Proprietor of the
Scandinavian Patent Office under the firm of L A Groth & Co 30 Finsbury
Pavement London E.C. “IMPROVEMENTS IN DRAWING APPARATUS FOR CONTINUOUS
SPINNING MACHINES" A communication to me from abroad by Richard Sebrke
of Berlin in the Empire of Germany
The apparatus forming the subject of this invention has for object the drawing
of the slubbings coming from the slubbing or condenser rollers and during the said
drawing to impart to such slubbings either a false twist, which is taken out again
by the action of the spinning spindles, or a light preliminary twist which is
continued further and completed by the action of the said spinning spindles.
The slubbing roller is moved by the drawing in roller which however can be
replaced by a pair of cylinders (Walzenpaar)
The slubbings are guided by a roller furnished with circular grooves and extend
to the drawing cylinders, consisting of two pairs of rollers rotating at different
speeds, the distance of which pairs of rollers from one another can be altered
according to circumstances.
:
Between these pairs of rollers are inserted small star wheels
The axis of these star wheels may have several diameters up to a conical or double
conical form and for some yarns the small star wheel may consist of complete double
cones on the surface of which are formed in the direction of the axis or more or less
inclined thereto channel formed grooves with half circular or curved cross section

page_text: These grooves are made so deep that the spaces between them can be used as
cogs for driving in such manner that the threads laying in such channels cannot be
touched by the teeth of the driving wheel. The star wheels take their bearings in
cases or shells and bear with their thicker inner bodies on the edge of a hoop,
whilst the tooth formed ends of the rays project through between each two case
hoops (Gehäusebügeln) and there gear with the teeth of the driving wheels. These
driving wheels receive their motion from cords on bevil wheels. The driving
mechanism is furnished with change wheels to enable the speed of the star wheels
and the difference between the speeds of the two pairs of drawing rollers to be
varied as required to suit the speed of the spindles.
The slubbing may be subjected to a drawing action while passing from the
slubbing and drawing in rollers to the first pair of drawing rollers by arranging
the relative speeds of such rollers accordingly.

LORENTZ ALBERT GROTH. K.G.V. Civil Engineer and Proprietor of the
Scandinavian Patent Office under the firm of L. A. Groth & Co 30 Finsbury

دو
The apparatus forming the subject of this invention has for object the drawing
of the slubbings coming from the slubbing or condenser rollers and during the said
drawing to impart to such slubbings either a false twist which is taken out again
by the action of the spinning spindles, or a light preliminary twist which is
continued further and completed, by the action of the said spinning spindles.
The slubbing roller a (see figure 1 of the drawings) is moved by the drawing in
roller 6 which however can be replaced by a pair of cylinders or rollers
(Walzenpaar)
The slubbings are guided by a roller c (see also figure 2) furnished with circular
grooves and extend to the drawing cylinders, consisting of two pairs of rollers de
and f, g, rotating at different speeds, the distance of which pairs of rollers from one
another can be altered according to circumstances. Between these pairs of rollers
are inserted small star wheels i. The axes h of these star wheels may have several
diameters up to a conical or double conical form h as shown in figures 1 and 4 and
for some yarns the small star wheel i may consist of complete double cones on the
surface of which are formed in the direction of the axis or more or less inclined
thereto channel formed grooves with half circular or curved cross section as shewn
in figures 3. 4 and 5
These grooves are made so deep that the spaces between them can be used as
cogs for driving in such manner that the threads laying in such channels cannot be
touched by the teeth of the driving wheel
The star wheels take their bearings in cases or shells o and bear with their
thicker inner bodies k on the edge of a hoop m whilst the tooth formed ends of
the rays project through between each two case hoops (Gehausebugeln) and there
gear with the teeth of the driving wheel n (figs 6 and 7) These driving wheels n
receive their motion from cords t or bevil wheels p, q, (see figure 6). The driving
mechanism is furnished with change wheels to enable the speed of the star wheels
and the difference between the speeds of the two pairs of drawing rollers to be
varied as required to suit the speed of the spindles
The slubbing may be subjected to a drawing action while passing from the
slubbing and drawing in rollers a, b, to the roller c or to the first pair of drawing
rollers de by arranging the relative speeds of such rollers accordingly
Having now described the nature of the said invention and the manner in which
the same is to be carried into effect I would have it understood that what I claim
as the invention to be secured by the within in part recited Letters patent is
First Imparting to the slubbing a false twist, or a permanent preliminary twist,
by means of a small toothed wheel i the axis of which may be formed of several
diameters of a cone, or of a double cone with channels cut therein, as hereinbefore
described and illustrated in the drawings hereto annexed,

page_text: Second The employment of the aforesaid small toothed wheel for twisting
several threads together.
In witness whereof I the said Lorentz Albert Groth have hereunto set my
hand and seal this sixteenth day of November in the year of our Lord
one thousand eight hundred and eighty two.
