PROVISIONAL SPECIFICATION.
An Improved Apparatus for Winding the Bobbins of Lace Machines.
1, PAUL MORITZ SCHIERSAND, of Kappel, near Chemnitz, in the Kingdom of
Saxony, German Empire, Director, do hereby declare the nature of this inven-
tion to be as follows:-
My present invention relates to winding-machines of the class which is used
for the purpose of winding shuttle-bobbins of looms, weaving net-lace and curtains,
and has for its object an improved arrangement for automatically throwing out
of gear, in connection with means for controlling the length of thread to be
wound upon the shuttle-bobbin. The latter arrangement comprises means for
uncoupling or disconnecting the same from the driving gear of the apparatus
and moving an index moving over a dial with divisions, so as to count the number
of meters, etc., from the zero point, whereupon, after exchanging the bobbins,
the machine can again continue its work.
The means for automatically uncoupling or ungearing the machine, consist
of a stop or pin arranged upon the dial and movable over the divisions indicating
the length of thread to be wound upon the bobbin. In this case the index is
in the beginning not moved over the zero-point but turned back to the stop.
A second index beneath the dial, but on the same vertical pivot as the first
index, is arranged to strike a lever at a certain point which latter is in con-
nection with the driving pulley, in such manner that the belt is thrown onto the
loose pulley and the machine is stopped, whereby the bobbin can be exchanged.
The great advantage obtained by the improved machine is, that there is no
necessity for the workman to keep a strict control over one machine to obtain an
equal winding on all bobbins, but can attend to a number of such, without fearing
an unequal winding and, in consequence, loss of thread.
In order to make my invention more clear, reference is had to the accom-
panying drawings, in which:
Figure 1 is a side elevation,
Figure 2 a top plan view,
Figures 3-5 are detail views of the dial mechanisms.
Tindicates a table resting on standards F. On the upper surface of said
table a brake-roller W is mounted in suitable bearings and over which the
threads, coming from the cross-bobbins run, in the direction indicated by the
arrow. Further a thread comb K is situated on the table, fastened in any.
desired manner, and in front of this a spindle a is arranged, journaled at L L,
carrying a cone-pulley S. The front-end of the table is provided with a counter-
shaft V, provided with fast- and loose-pulleys V and V2 is a dial with
divisions, which are numbered. The vertical pin of this dial carries an index z,
which by means of gears r, shaft w, worm-wheel and worms, all driven by the
brake-roller, is rotated. The gearing of the index-driving mechanism must be
so chosen, that the index points out the unit of measure in metres or any other
desired measure, so that the length of the thread, having passed over the brake-
roller, or having been wound upon the bobbin, can immediately be read on the

page_text: dial. Before placing new bobbins upon the spindle a, the workman, after having
uncoupled the worm-wheel from the shaft w by the handle H, moves the index
back to the zero-point by turning the hand-wheel b, whereupon the coupling is
again engaged.
After the bobbins have been placed upon the shaft a, the driving gear is
engaged and, when the position of the index indicates, that the necessary length
of thread has been wound upon the bobbin, the driving mechanism VVɩ yo
is again disengaged to exchange the bobbins and so on.
To obtain the advantage of providing the bobbins with threads of the same
length, and that the work-man can attend to a number of machines, the following
arrangement has been found essential..
On the division dial a, a stop or pin y is attached, being adjustable so as to
be moved over the divisions. The workman, in the beginning, does not move the
index to the zero point, but turns the same back to the stop y. Beneath the dial,
a second arm h¹ is arranged, which, at a certain point, (the zero-point of the upper
index) strikes against a lever 2 being in connection with the lever for putting
in or out of gear, by means of a connecting rod 3. The lever h³, as soon as the
machine is engaged, enters a notch of the rod, carrying the belt-guide. The
rod his acted upon by a spring 46 in such a manner to cause the belt-guide to
move upon the loose pulley. When the arm h¹ strikes the lever ², the lever h³,
for putting in or out of gear, is raised out of the notch of the rod 5, which latter
can then be moved by the spring, so as to bring the belt upon the loose pulley.
By this means the machine is automatically brought to a stand-still as soon
as the necessary length of thread has run upon the bobbins and it is obvious that,
as long as the stop y is not adjusted, all bobbins must receive an equal quantity
of thread.

An Improved Apparatus for Winding the Bobbins of Lace. Machines.'
I, PAUL MORITZ SCHIERSAND, of Kappel,, near Chemnitz, in the Kingdom-of
Saxony, German Empire, Director, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My present invention relates to winding-machines of the class which is used
for the purpose of winding the bobbins of lace machines, and has for its object
an improved arrangement for automatically throwing the machine out of gear,
in connection with means for controlling the length of thread to be wound upon
the bobbin. The latter arrangement comprises means for uncoupling or discon-
necting the same from the driving gear of the apparatus and turning an index
hand moving over a dial with divisions, so as to count the number of metres,
etc. from the zero point, whereupon after exchanging the bobbins, the
machine can again continue its work.
The means for automatically uncoupling or ungearing the machine, consist
of a stop or pin arranged upon the dial and adjustable upon the divisions indicating
the length of thread to be wound upon the bobbin. In this case the index is
in the beginning not stopped over the zero-point but is turned back to the stop.
A second index beneath the dial, but on the same vertical pivot as the first

page_text: index, is arranged to strike a lever at a certain point which latter is in con-
nection with the driving pulley, in such a manner that the belt is thrown on to
the loose pulley and the machine is stopped, allowing the bobbin to be exchanged.
The great advantage obtained by the improved machine is that there is no
necessity for the workman to keep a strict control over one machine to obtain an
equal winding on all bobbins, but can attend to a number of machines, without
fearing an unequal winding and, in consequence thereof, loss of thread.
the
In order to make my invention more clear, I refer to the drawings filed with
provisional application in which:
Figure 1 is a side elevation,
Figure 2 a top plan view,
Figures 3-5 are detail views of the dial mechanisms.
T indicates a table resting on standards F. On the upper surface of said
table a brake-roller W is mounted in suitable bearings and over which the
threads, coming from the reels run in the direction indicated by the arrow.
Further a thread comb K is situated on the table, fastened in any desired manner,
and in front of this a spindle a is arranged, journaled at L L, carrying a
step-pulley S. The front end of the table is provided with a driving spindle V,
provided with fast- and loose-pulleys V1 and V2. a is a dial with divisions,
which are numbered. The vertical pin of this dial carries an index z, which is
rotated by means of gears 1, shaft w, worm-wheel and worms, all driven
by the brake-roller. The gearing of the index driving mechanism must be
so chosen, that the index points out the unit of measure in metres or any other
desired measure, so that the length of the thread, having passed over the brake-
roller, or having been wound upon the bobbin, can immediately be read on the
dial. Before placing new bobbins upon the spindle «, the workman, after having
uncoupled the worm-wheel from the shaft w by the handle H, moves the index
back to the zero-point by turning the hand-wheel b, whereupon the coupling is
again engaged.
After the bobbins have been placed upon the shaft a, the driving gear is
engaged and, when the position of the index indicates that the necessary length
of thread has. been wound upon the bobbin, the driving mechanism V V1 V2
is again disengaged to exchange the bobbins and so on.
To obtain the advantage of providing the bobbins with threads of the same
length, and allowing the workman to attend to a number of machines, the
following arrangement has been found essential.
On the division dial a, a stop or pin y is fitted, being adjustable so as to be
fixed at any of the divisions. The workman, in the beginning, does not turn
the index to the zero point, but turns it back to the stop y. Beneath the dial,
an arm is arranged, which, at a certain point, (the zero-point of the upper
index) strikes against a lever h² in connection with the lever for putting the
driving spindle in or out of gear, by means of a connecting-rod h³. The lever h4,
as soon as the machine is engaged, enters a notch of the rod, carrying the belt-
guide. The rod h5 is acted upon by a spring in such a manner to cause the
belt-guide to move upon the loose pulley. When the arm h' strikes the lever h²,
the lever h, is disengaged from the notch of the rod h, which latter can then be
moved by the spring 6, so as to bring the belt upon the loose pulley. By this
means the machine is automatically brought to a stand-still as soon as the
necessary length of thread has run upon the bobbins and it is obvious that, as
long as the stop y is not shifted, all bobbins must receive an equal quantity of
thread.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. An improved winding apparatus of the class employed for the purpose of
winding bobbins of looms for weaving net-lace and curtains, consisting of a

page_text: brake-roller W, over which the threads pass, a spindle a driven by a step-pulley S
and carrying the bobbins, upon which the thread is wound, and gearing consisting
of fast and loose pulleys V1 V2 to drive the bobbin-shaft, substantially as described.
2. An improved winding apparatus of the class employed for the purpose of
winding bobbins of looms for weaving net-lace and curtains, comprising a dial,
with numbered divisions over which an index can be moved by means of a
gearing r, the shaft w of which is driven by a worm arranged upon the shaft of
the, brake-roller W, said worm engaging in a worm-wheels of the shaft w, a
coupling to engage and disengage the latter, another gear arranged upon the
shaft, which gear by means of a hand-wheel H can be rotated, when the.
shaft wand brake-roller are uncoupled in order to adjust the index, substantially
as described.
3. An improved winding apparatus of the class employed for the purpose of
winding bobbins of looms for weaving net-lace and curtains, comprising a dial
provided with a stop y adjustable upon the divisions of the dial indicating the
length of thread, an index z pointing out the units of measure which before
starting the machine is moved back to the stop y, an arm on the pivot of
the index beneath the dial, arranged to strike a lever h² at the zero point of the
index, a rod h³ connecting said lever with the lever 4 for putting in or out
of gear said lever + which enters the notch of a rod 5 carrying the belt guide,
and a spring acting upon the belt guide to draw the belt on to the loose pulley,
substantially as described.
