An Improved Machine for Removing Bobbins from the Shuttles in
Looms for Weaving Curtains and Net Lace.
I, PAUL MORITZ SCHIERSAND, of Kappel, near Chemnitz, in the Kingdom of
Saxony, German Empire, Director, do hereby declare the nature of this invention
to be as follows:-
Hitherto boys were employed for removing bobbins from the shuttles of
looms for weaving curtains and net lace, whereby it very often happened that
not only the brake springs of the shuttles, but also the bobbins were injured,
which injuries besides the necessary repairs cause rather troublesome regulations.
The object of my invention is to provide a machine effecting the same work
more rapidly than it hitherto was possible without risking injury to the bobbins
and the brake spring.
My invention will be more fully understood with reference to the accompany-
ing drawings, in which the machine is illustrated in different sections. The
shuttles S carrying bobbins B are inserted in a tube like receptacle H in form
corresponding to the shuttles and fixed to the machine frame A¹ by means of a
standard H. A disc G rotates at short intervals and removes the shuttles from
the said receptacle H. The disc G is provided with a number of openings similar
to the form and size of the shuttles and is rotated in such manner that the open-
ings successively come to lie underneath the receptacle H. In the moment of
each stopping of the disc G a shuttle from the receptacle H falls down in the
opening of the disc G lying vertically below and during the next step of rotation
is withdrawn from I-II, Figure 1.
In the position II a lever J'influences the bobbin B and presses the same some-
what downwards and out of the regular way, so that it freely can drop down after
the lever J has returned into its original position. The shuttle during the next
step of the disc G is brought into position III, Figure 1, in which it drops down
through an opening of the disc Carranged underneath the disc G. The released
bobbins and shuttles either are conducted into a receptacle or upon rods K,
Figure 2. In this manner the machine works continuously and the workman
only has to insert complete shuttles in the receptacle H and to remove the emptied
shuttles from the rods K. The rocking movement of the disc is effected by means
of the main driving shaft L of the machine, the motion of which is transmitted
by a disc N¹, by a crank lever 0 rotating around 0¹, carrying a friction roller
and being pressed against the disc N¹ by means of a spring 0. Furthermore
for rotating the disc I provide a connecting-rod 02, a rack 05 fixed by means of
bolts 00, a lever D oscillating around the bolt Q fixed upon the machine frame
and provided with a gear into which engages the rack. The free extremity of
this lever is of hook form and engages with the lower bolt 1 of the cross-arms F
rotating around Q whereby the upper bolt F2 engages into holes of the disc G.
Figure 3 illustrates the disc C after the disc G is removed, and Figure 5 illus-
trates the cross arms F after removal of the discs G and C. In order to secure
the dise G in position after each rocking and in the moment where the openings

page_text: are lying just underneath the receptacle H or underneath the openings of the
discs C, the circumference of the same is provided with so many recesses as there
are openings. Into these recesses engages a lever R, fixed to the machine frame
and pressed against the circumference of the disc & by means of a spring R¹.
The movement of the lever J' is introduced by the disc Na actuating the crank
lever J oscillating around J2. The one end of this crank lever by means of the
spring J is pressed against the disc whilst the lever J¹ fixed to the other
extremity of said crank by a spring P1 is drawn downwards and slides with its
lower edge over the point 12 fixed upon P, whereby besides the to- and fro-
motion the up- and downwards movement necessary for removing the bobbin is
attained.
Figure shows the lever J in the position in which the bobbin is removed.
Figure 6 shows the same lever in raised position in which the disc G advances.
Figure 4 illustrates a section through the machine parallel to the main driving
shaft. The latter runs in bearings L' suitably arranged upon the machine
frame A¹. One of these bearings is somewhat elongated so as to be adapted for
receiving the bolt O¹. M illustrates the main driving shaft of the machine.
Instead of the rotating disc G, a slide effecting a to- and fro-motion might be
employed for transporting the shuttles. Furthermore the disc G. can be provided
with a greater number of openings and the machine might have a greater number
of bobbin receptacles H so that a multiple work can be effected.

An Improved Machine for Removing Bobbins from the Shuttles in
Looms for Weaving Curtains and Net Lace.
I, PAUL MORITZ SCHIERSAND, of Kappel, near Chemnitz, in the Kingdom of
Saxony, German Empire, Director, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Hitherto boys have been employed for removing bobbins from the shuttles of
looms for weaving curtains and net lace, whereby it has very often happened that
not only the brake springs of the shuttles, but also the bobbins have been injured,
which injuries besides the necessary repairs caused rather troublesome regulations.
The object of my invention is to provide a machine effecting the same work
more rapidly than it hitherto has been possible without risking injury to the
bobbins and the brake spring.
My invention will be more fully understood with reference to the drawings filed
with the provisional application, in which the machine is illustrated in different
sections. The shuttles S carrying bobbins B are inserted in a tube like recep-
tacle H in form corresponding to the shuttles and fixed to the machine frame A¹
by means of a lever H¹. A disc G rotates at short intervals and removes the
shuttles from the said receptacle H. The disc G is provided with a number of
openings similar to the form and size of the shuttles and is rotated in such
manner that the openings successively come to lie underneath the receptacle H
In the moment of each stopping of the disc G a shuttle from the receptacle H
falls down in the opening of the disc Glying vertically below and during the
next step of rotation is moved from position I to position II, Fig. I.
In the position II the end of a lever J' enters the square hole of the bobbin B

page_text: and presses it slightly downwards and out of the regular way, so that it can freely
drop down through a hole in the disc C, after the lever J has returned into its
original position. The shuttle during the next step of the disc G is brought into
position III, Figure 1, in which it drops down through the opening of the disc C
arranged underneath the disc G. The released bobbins and shuttles are either
conducted into a receptacle or upon rods K, Figure 2. In this manner the
machine works continuously and the workman only has to insert complete
shuttles in the receptacle H and to remove the emptied shuttles from the rods K.
The intermittent movement of the disc is effected by means of the main driving
shaft L of the machine, the motion of which is transmitted by a disc N', by a
crank lever rotating around O', carrying a friction roller and being pressed
against the disc N' by means of a spring 0. Furthermore for rotating the
dise GI provide a connecting-rod 02, a rack 05 sliding upon bolts 03 04, a lever D
oscillating around the bolt fixed upon the machine frame and provided with a
gear into which engages the rack. The free extremity of this fever is of hook
form and engages with the lower bolt of the cross-arms Frotating around Q,
whereby the upper bolt F2 engages into holes of the disc G.
Figure 3 illustrates the disc after the disc G is removed, and Figure 5 illus-
trates the cross arms F after removal of the discs G and C. In order to secure
the dise G in position after each rocking and in the moment where the openings
are lying just underneath the receptacle H or above the openings of the
discs C, the circumference of the same is provided with as many recesses as there
are openings. Into these recesses engages a lever R, fixed to the machine frame
and pressed against the circumference of the disc G by means of a spring R.
The movement of the lever J₁ is caused by the disc N actuating the crank
lever Joscillating around J2. The one end of this crank lever by means of the
spring J is pressed against the disc whilst the lever J' fixed to the other
extremity of said crank by a spring 1" is drawn downwards and slides with its
lower edge over the point P2 fixed upon P, whereby besides the to- and fro-
motion the up- and downwards movement necessary for removing the bobbin is
attained.
Figure 2 shows the lever J in the position in which the bobbin is removed.
Figure 6 shows the same lever in raised position in which the disc G advances.
Figure 4 illustrates a section through the machine parallel to the main driving
shaft. The latter runs in bearings L' suitably arranged upon the machine-
frame A¹. One of these bearings is somewhat prolongated so as to be adapted for
receiving the bolt O¹. M illustrates the main driving pulley of the machine.
Instead of the rotating disc G, a slide effecting a to- and fro-motion might be
employed for transporting the shuttles. Furthermore the disc G can be provided
with a greater number of openings and the machine might have a greater number
of bobbin receptacles H, so that a multiple work can be effected.
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. A machine for automatically removing bobbins from the shuttles in looms
for weaving net-lace and curtains, consisting of a disc G having openings con-
forming to the size of the shuttles, and a disc Carranged underneath said disc G,
having two openings, one conforming to the size of the bobbins and the other
to that of the shuttles, for the purpose of allowing the bobbins after each rocking
movement of the disc G to be pressed through a hole of the latter and through
the corresponding hole of the disc and to be gathered in a suitable receptacle
or upon rods, whilst during each movement of said disc G each disconnected
shuttle is carried by the latter to the other hole of the disc C, so as to fall through
the same and to be gathered in a suitable receptacle or upon a rod, means for
actuating said disc and means for pressing the bobbins from the shuttles, sub-
stantially as described.
