Improvements in Spinning Mules for Automatically Taking Up
Broken Rovings.
I, PETER JENSEN of 77 Chancery Lane London Chartered Patent Agent, do
hereby declare the nature of this invention (a communication to me from abroad
by Alphonse Kremer of Ettelbrück, Luxemburg, Spinning Mill Manager) to be
as follows:-
:-
The threads which break on the self actor mule during fine-spinning are, as is
well known, taken up by workmen who attach them to the spindles. It happens
however often that the workman takes up from the table and attaches the broken
roving after the carriage has run wholly or partly out, whereby thick parts
cannot be avoided in the thread. But the attaching is in any case a tedious one
and seriously diminishes the output especially with the less valuable spinning
materials.
The object of this invention is automatically to attach the broken roving to the
spindles and thus save labour and avoid the aforesaid evils.
The invention consists essentially of a zigzag curve the bays of which take up
the broken off rovings which then attach themselves to the spindle points while the
latter temporarily lie in these bays.
The zigzag line may be formed by forks arranged close to each other.
The forks have splayed branches and are at the end of the round neck continua-
tions of square shanks. Round each neck there is a helical spring. The other
end of the shank is screwed and has a thumb nut. These fork shanks are passed
through an upper and a lower guide frame and the fork points touch the points of
the adjoining forks, so as to form in plan a zigzag line or as many bays as there
are forks.
The springs tend to push the forks forward against the spindle points and
produce a yielding action between the fork bays and the spindle points. The
thumb nuts afford facility for adjusting the fork shanks in their bearings.
The broken roving threads lying in the forks will be taken up by the spindle
points touching them after a few turns. Hence the spindle points and the forks
must be so near each other that this contact becomes possible. Yet an actual
contact between fork and spindle must be avoided as otherwise by the friction
between the rotating spindle points and the forks the rovings would be cut
through.
The zigzag line is therefore so arranged against the drawing frame that the
spindle points turn round and take up the broken threads without however touching
the forks, when the self actor carriage has been run completely in.
In order that this taking up may be done with certainty the spindle points have
to turn some little time in the forks. This is effected by making the fork
apparatus movable under the drawing frame in such manner that the spindle points,
when the self-actor carriage has been quite run in, lie in the forks and when the
carriage then runs out, the fork apparatus follows it a short distance so that the
spindle points remain some time in contact with the broken roving end which bangs
in the fork and thus finds opportunity to take hold of it and wind it on itself.
The fork apparatus then goes back under the drawing frame in order to receive
the carriage again.
If the roving should tear close to the drawing frame during the return passage

of the fork apparatus it would drop down between the forks and thus not
be automatically taken up. In order to avoid this the fork apparatus is
provided with a cover placed over the forks and cut zigzag shape to suit.
roving torn off short, drops onto this cover and would remain thereon if the fork
apparatus in the back stroke did not push in under an upstanding ledge arranged
in front of the drawing frame and this ledge will push the roving into the fork
opening.
The fork shafts may as a modification be fixed in one frame by means of a nut
at each end of a screw threaded part of the shalt.
In order to give the fork apparatus reciprocating motion it is mounted on knee-
shaped bent bars to which are fixed rods which move in bearings on the roller
frame table. When using the last named fork shaft arrangement and in order to
prevent the too hard contact between spindle and fork in the in- and outstroke of
the carriage small stops are provided on the spindle table near the spindles or in
any other suitable part of the carriage, which stops abut against set screws on the
lower ends of the aforesaid knee bars. The aforesaid rods are at their other ends
fixed to a common cross bar which can slide on the rear part of the roller frame
table and are fastened to endless chains passing over two rollers. The latter are
fixed on a spindle arranged behind and parallel to the roller table; the aforesaid
rollers are so wide as to carry also a chain with weight attached tending to turn
the roller forward.
On the said spindle next to the headstock is fixed the main wheel which carries
a chain. The latter is at one end attached to the main wheel rim and at the other
to the carriage running on rails below the self actor carriage and having a stop;
the chain encircles the main wheel and a lower guide roller. Next to the main
wheel is fixed a pawl wheel, in front of which is a pawl working in a guide and
connected by a lever with a push rod with push knob. A spring tends to press the
pawl against the pawl wheel.
The carriage below the self actor carriage runs on a line of rails having a gap
or interrupted portion.
The action as influenced by the self actor carriage is as follows:-
1. The fork apparatus when drawn in rests under the drawing frame, the chain
weights are drawn up, the lower carriage has been run out and the pawl is in the
pawl wheel.
The self actor carriage has run in and the spindle points turn in the forks. At
the last moment of running in a knob on the self actor carriage strikes the push
rod knob whereby the pawl is pulled out of its tooth; the knob is advantageously
fixed so that it may be removed in order that the fork apparatus when the self
actor carriage after having been run in shall remain at rest and not rebound.
Where the construction of the self actor admits of it the striking gear or strap
shifting bar for stopping the motion of the carriage may be used for fixing the
knob thereto because by the motion of that bar the knob would also be pushed so
far forwards as not to hit the push rod knob. The chain weights now begin to
turn the rollers the main shaft the pawl wheel and the main wheel forward. The
fork apparatus will thus slide forward and follow the self actor carriage in its out
passage until the cross bar pushes against the stop. The main wheel will wind up
the chain and draw in the lower carriage. The pawl acted upon by its spring
glides on the circumference of the pawl wheel as the pressure on the pusher knob
ceases at once after the out-passage of the self actor.
2. The fork apparatus has slided out, the pawl is in the pawl wheel and has thus
stopped the rotation of the main shaft caused by chain weights. The lower carriage
has been drawn in, the self actor carriage continues to move out.
3. The outmoving self actor carriage lays hold of the carriage below it by means
of an arm coming against a stop on the said lower carriage and carries it along
with it. The chain is pulled and turns the main wheel and its shaft back, so
that the fork apparatus is drawn in under the drawing frame, the chain weights
being raised.

page_text: 4. The lower carriage drops into the gap so that the stop on it and the arm on
the self actor carriage come out of gear and the lower carriage stops while
simultaneously the pawl goes into the pawl wheel.
The chain weights are now raised and the fork apparatus drawn in, so that after
the self-actor carriage has been run in the apparatus can again enter the phase 1.

Improvements in Spinning Mules for Automatically Taking Up
Broken Rovings.
I, PETER JENSEN of 77 Chancery Lane, London Chartered Patent Agent
do hereby declare the nature of this invention (a communication to me from
abroad by Alphonse Kremer of Ettelbrück Luxemburg Spinning Mill Manager)
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
The threads which break on the self actor mule during fine-spinning are as is
well known taken up by workmen who attach them to the spindles. It. happens
however often that the workman takes up from the table and attaches the broken
roving after the carriage has run wholly or partly out, whereby thick parts cannot
be avoided in the thread. But the attaching is in any case a tedious one and
seriously diminishes the output especially with the less valuable spinning materials.
The object of this invention is automatically to attach the broken roving to the
spindles and thus save labour and avoid the aforesaid evils.
The invention consists essentially of a zigzag curve the bays of which take up
the broken off rovings which then attach themselves to the spindle points while
tke latter temporarily lie in these bays.
The zigzag line may be formed by forks arranged close to each other as shewn
in Figs. 1 and 2.
The forks g have splayed branches and are at the end of the round neck con-
tinuations of square shanks s. Round each neck there is a helical spring. The
other end of the shank is screwed and has a thumb nut. These fork shanks are
passed through an upper and a lower guide frame and the fork points touch the
points of the adjoining forks, so as to form in plan a zigzag line or as many bays
as there are forks, see Figs. 3 and 8.
The springs tend to push the forks forward against the spindle points and
produce a yielding action between the fork bays and the spindle points thus
avoiding a too hard contact between them. The thumb nuts afford facility for
adjusting the fork-shanks in their bearings.
The broken roving threads lying in the forks will be taken up by the spindle
points touching them after a few turns. Hence the spindle points and the forks
must be so near each other that this contact becomes possible. Yet an actual
contact between fork and spindle must be avoided as otherwise by the friction
between the rotating spindle points and the forks the rovings would be cut
through. The zigzag line is therefore so arranged against the drawing frame
that the spindle points turn round in the bays and take up the broken threads
without however touching the forks, when the self actor carriage has been run
completely in.
In order that this taking up may be done with certainty it is provided that the
spindle points turn some little time in the bays. This is effected by making the
fork apparatus movable under the drawing frame in such manner that the spindle
points when the self actor carriage has been quite run in lie in the forks and when

page_text: the carriage then runs out the fork apparatus follows it a short distance so that
the spindle points remain some time in contact with the broken roving end which
hangs in the fork and thus finds opportunity to take hold of it and wind it on itself.
The fork apparatus then goes back under the drawing frame in order to receive
the ingoing carriage again.
If the roving should tear close to the drawing frame during the return passage
of the fork apparatus it would drop down between the forks and thus not be
automatically taken up. In order to avoid this the fork apparatus is provided
with a cover d placed over the forks and cut zigzag shape to suit. The roving
torn off short drops on to this cover and would remain thereon if the fork
apparatus in the back stroke did not push in under an upstanding ledge b arranged
in front of the drawing frame and this ledge will push the roving into the fork
opening.
The fork shafts may as a modification be fixed in one frame Figs. 4 and 5 by
means of a nut s' at the end of a screw threaded part of the shaft.
In order to give the fork apparatus G reciprocating motion it is mounted ou
knee-shaped bent bars t to which are fixed rods z which move in bearings on the
roller frame table. When using the last named fork-shaft arrangement Figs. 4
and 5 and in order to prevent the too hard contact between spindle and fork in the
in and outstroke of the carriage small stops al are provided on the spindle table
near the spindles or in any other suitable part of the carriage, which stops abut
against set screws u¹ on the lower ends t¹ of the aforesaid knee hars t see Figs. 6
and 7. The aforesaid rods z are at their other ends fixed to a common cross
bar 9, which can slide on the rear part of the roller frame table and are fastened
to endless chains k passing over two rollers rpd. The rollers r are fixed on a
spindle w arranged behind and parallel to the roller table: the aforesaid rollers are
so wide as to carry also a chain with weight e attached tending to turn the roller r
forward.
On the said spindle w next to the head-stock is fixed the main wheel R which
carries a chain K. The latter is at one end attached to the main wheel rim and
at the other to the carriage W running on rails below the self actor carriage and
having a stop n; the chain encircles the main wheel and a lower guide roller o.
Next to the main wheel is fixed a pawl wheel m, in front of which is a pawl i
working in a guide fand connected by a lever with a push rod with push knob a.
A spring p tends to press the pawl against the pawl wheel.
The carriage W below the self actor carriage runs on a line of rails having a
gap or interrupted portion r.
The action as influenced by the self actor carriage is as follows:
1. The fork apparatus & Fig. 6. when drawn in rests under the drawing frame,
the chain weights e are drawn up, the lower carriage W has been run out and the
pawl is in the pawl wheel.
The self actor carriage has run in and the spindle points turn in the forks. At the
last moment of running in a knob on the self-actor carriage strikes the push
rod knob whereby the pawl is pulled out of its tooth; the knob y is
advantageously fixed so that it may be removed in order that the fork apparatus
when the self-actor carriage after having been run in shall remain at rest and not
rebound. Where the construction of the self actor admits of it the striking gear
or strap shifting bar for stopping the motion of the carriage may be used for fixing
the knob y thereto because by the motion of that bar the knob would also be
pushed so far forwards as not to hit the push rod knob. The chain weights e now
begin to turn the rollers the main shaft w the pawl wheel m and the main wheel R
forward. The fork apparatus G will thus slide forward and follow self-actor
carriage in its out passage until the crossbar 9 pushes against the stop d.
main wheel R will wind up the chain K and draw in the lower carriage W. The
pawl acted upon by its spring p glides on the circumference of the pawl wheel as
the pressure on the pusher knob u ceases at once after the out-passage of the
self-actor.
The

page_text: 2. The fork apparatus G Fig. 7 has slided out, the pawl i is in the pawl wheel
and has thus stopped the rotation of the main shaft W caused by chain weights e,
the lower carriage W has been drawn in, the self-actor carriage continues to
move out.
3. The outmoving self-actor carriage Fig. 9 lays hold of the carriage W below
it by means of an arm A coming against a stop n on the said lower carriage W
and carries it along with it. The chain K is pulled and turns the main wheel R
and its shaft w back, so that the fork apparatus is drawn in under the drawing
frame, the chain weight e being raised.
4. The lower carriage W Fig. 10 drops into the gap so that the stop u on it
and the arm A on the self-actor carriage come out of gear and the lower carriage
stops while simultaneously the pawl i goes into the pawl wheel m.
The chain weights e are now raised and the fork apparatus G drawn in, so that
after the self-actor carriage has been run in the apparatus can again enter the
phase 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
Device for automatically taking up, bringing up, and again attaching broken
rovings to the spindle points of the self-actor carriage consisting of a fork
apparatus G in front of and parallel with the drawing frame the bays of said
apparatus taking up the broken off rovings and attaching them to the spindle points
when they come into the said bays in the in-stroke of the carriage, substantially as
described and shewn.
