Improvements in Machines for Inserting Bobbins into the Carriages
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 invention
to be as follows:-
-
My present invention relates to a new and improved method of, and means for
automatically inserting bobbins into shuttles of looms, for weaving net-lace and
curtains. This automatic work is done in such a manner, that the shuttles and
bobbins separately arranged in appropriate devices (tubes or guard rails) are
taken from these receptacles, one by one, and the bobbin inserted into the
opening of the shuttle, for which reason the friction spring of the shuttle is
sent back, then again brought into normal acting position, and after this the
thread drawn through the eye of the shuttle, whereupon the complete shuttle
is delivered into a collecting receptacle.
In order that this invention may be more clearly described, reference is had
to Figures 1-6 of the accompanying sheet of illustrative drawing, in which
similar letters denote similar parts throughout the different views.
The shuttles c, as well as the bobbins B are separately piled up in tubes or
other receptacles, or are piled on a guide, both being arranged on the table T of
the machine. The lower shut off of the tubes or the like is accomplished by
slides C or B, guided in the table and the widths of which are about the same
as that of the shuttles and the bobbins. These slides can be moved to and fro,
so that the openings of the tubes or receptacles are alternately opened and closed.
The movement of the slides is obtained by a driving shaft W, by means of cam-
discs, levers and draw-bars. The slide C is actuated by the cam disc C*,
lever C3 and draw-bar C2; the slide B by the cam disc B, lever 13 and draw-
bar B.
When the machine is in work, the slide C¹ is first drawn back and consequently
the shuttle of the tube is caused to sink by its own gravity a distance, corre-
sponding to the width of the slide and to take a position in front of the slide C
upon the table T (Figure 1). This slide now moves back again and thereby
forces the shuttle out of the tube from the side and so far, till the same falls into
the opening of the table, which is exactly as large as the shuttle.
The open-
ing is closed from the bottom by the slide D¹, the latter being guided in the
table and actuated by the cam-disc D+, lever D³ and draw-bar D2.
Figure 1 illustrates the machine in that position, in which a shuttle C¹ has
been forced into the opening 0, whereas the slide has been again drawn back
and a further shuttle from the tube been placed in front of the same.
During the backward movement of the slide C¹, the slide B¹ has advanced and
forced a bobbin out of the receptacle B and moved the same exactly over the
opening of the shuttle C. The bobbin B1 by this time has reached its position
under a spring F, attached to the table T, and is already being pressed into the

page_text: opening of the shuttle C¹. The bobbin is forced in by the spring F until the disc
edges of the bobbin engage over the nose or flange of the shuttle opening, and
the thread passed through the eye L of the shuttle.
To accomplish this, a lever E is pivoted to the table T, and is at one end
provided with a roller E³ resting and sliding upon an excentric E, so that the
lever is so raised, that a hook E attached to the other end, passes through the
eye L of the shuttle (Figures 4 & 5). On the same end of the lever, carrying
the hook, a stop or pin E is arranged, which, when the lever is raised, presses
a spring R, attached to the slide D¹, upwards so that a nose or pin n of the same
passes through an opening in the slide D' and is brought in front of the friction
spring (Figures 4 & 5). At the same time the slide D₁ makes a slight movement
forward and the pin n presses the friction-spring backwards, so that the bobbin
can completely enter the opening of the shuttle. After this has been accom-
plished, the lever E' again descends, whereby the hook E grasps the thread and
draws the same through the eye of the shuttle, whereupon the pin n, influenced
by its spring R, moves back, so that the friction spring can again take up its
normal position, the nose of the same entering the space between the discs of
the bobbin.
The bobbin has thereby been completely introduced and the slide D', locking
the opening of the table, is now drawn back, so that the shuttle can fall
through and downward upon a rail H, on which the same is filed (Figure 6) or
into a spout, by which the shuttle is delivered to a suitable receptacle.
As it is essential to ensure the bobbin-thread being always grasped by the
hook E and in the right way, the following arrangement is preferred. The spout
or tube, as receptacle for the bobbins, is provided with a longitudinal slot, and
when the bobbins are inserted, all thread-ends are drawn through the slot to
extend outwards (Figures 2 & 5 at G). The thread of the bobbin, moved
forward, is then forced toward the hook E, having passed through the eye of the
shuttle, by means of a push J attached to a lever J¹, so that, when the hook is
again forced down through the shuttle-eye, it is compelled to take the thread
along (Fig. 5). The lever J is driven by a cam-disc J³, against which the end
of the lever, provided with an antifriction roller, presses. The levers C³, 133, 13
and J are kept in contact with the cam-dises by means of springs suitably
arranged whereas the downward movement of the lever E¹ is caused by its own
gravity.

Improvements in Machines for Inserting Bobbins into the Carriages
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 invention.
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 a new and improved method of, and means for
automatically inserting bobbins into shuttles of looms, for weaving net-lace and
curtains. This automatic work is done in such a manner, that the shuttles and
bobbins separately arranged in appropriate devices (tubes or guard rails) are

page_text: taken from these receptacles, one by one, and the bobbin inserted into the
opening of the shuttle, for which purpose the friction spring of the shuttle is
sent back, then again brought into normal acting position, and after this the
thread drawn through the eye of the shuttle, whereupon the complete shuttle
is delivered into a collecting receptacle.
In order that this invention may be more clearly described, reference is had
to Figures 1-6 of the drawing filed with the Provisional Application, in which
similar letters denote similar parts throughout the different views.
The shuttles C, as well as the bobbins B are separately piled up in tubes or
other receptacles, or are piled on a guide, both being arranged on the table T of
the machine. The lower shut off of the tubes or the like is accomplished by
slides C or B¹, guided in the table and the widths of which are about the same
as that of the shuttles and the bobbins. These slides can be moved to and fro,
so that the openings of the tubes or receptacles are alternately opened and closed.
The movement of the slides is obtained by a driving shaft W by means of cam-
discs, levers and draw-bars. The slide C₁ is actuated by the cam disc C*,
lever C3 and draw-bar C2, the slide B¹ by the cam disc B3, lever 133 and draw-
bar Ba.
When the machine is in work, the slide C¹ is first drawn back and consequently
the shuttle of the tube is caused to sink by its own gravity a distance corre-
sponding to the width of the slide and to take a position in front of the slide C¹
upon the table T (Figure 1). This slide now moves back again and thereby
forces the shuttle out of the tube from the side until it falls into the opening
of the table, which is exactly as large as the shuttle. The opening () is closed
from the bottom by the slide D¹, the latter being guided in the table and actuated
by the cam-disc D4, lever D³ and draw-bar D
Figure 1 illustrates the machine in that position, in which a shuttle C¹ has
been forced into the opening O, whereas the slide C¹ has been again drawn back
and a further shuttle from the tube been placed in front of the same.
During the backward movement of the slide C¹, the slide B¹ has advanced and
forced a bobbin B out of the receptacle and moved the same exactly over the
opening of the shuttle C. The bobbin B by this time has reached its position
under a spring F, attached to the table T, and is already being pressed into the
opening of the shuttle C¹ as far as is allowed by the friction spring F. This
permits the bobbin to completely enter the shuttle-opening and also the nose of
the same to be placed between the discs of the shuttle and the thread to be fed
through the eye L of the shuttle.
To accomplish this, a lever E' is pivoted to the table T, and is at one end
provided with a roller E3 resting and sliding upon an eccentric E4, so that the
lever is so raised, that a hook E attached to the other end, passes through the
eye L of the shuttle (Figures 4 & 5). On the same end of the lever, carrying
the hook, a stop or pin E is arranged, which when the lever is raised, presses
a spring R, attached to the slide D', upwards so that a nose or pin n of the same
passes through an opening in the slide D¹ and is brought in front of the friction
spring (Figures 4 & 5). At the same time the slide D makes a slight movement
forward and the pin n presses the friction-spring backwards, so that the bobbin
can completely enter the opening of the shuttle. After this has been accom-
plished, the lever E' again descends, whereby the hook E grasps the thread and
draws the same through the eve of the shuttle, whereupon the pin n, influenced
by its spring R¹, moves back, so that the friction spring can again take up its
normal position, the nose of the same entering the space between the discs of
the bobbin,
The bobbin has thereby been completely introduced and the slide D', locking
the opening of the table, is now drawn back, so that the shuttle can fall
through and downward upon a rail H, on which the same is filed (Figure 6) or
into a spout, by which the shuttle is delivered to a suitable receptacle.
As it is essential to ensure the bobbin-thread being always grasped by the

page_text: hook E and in the right way, the following arrangement is preferred. The spout
or tube, as receptacle for the bobbins, is provided with a longitudinal slot, and
when the bobbins are inserted, all thread ends are drawn through the slot to
extend outwards (Figures 2 & 5 at G). The thread of the bobbin, moved
forward, is then forced toward the hook É having passed through the eye of the
shuttle, by means of a push J attached to a lever J¹, so that, when the hook is
again forced down through the shuttle-eye, it is compelled to take the thread
along (Fig. 5). The lever J¹ is driven by a cam-disc J2, against which the end
of the lever, provided with an antifriction-roller, presses. The levers C³, 133, D³
and J are kept in contact with the cam-discs by means of springs suitably
arranged whereas the downward movement of the lever E¹ is caused by its own
gravity.
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 selfacting machine for inserting bobbins into shuttles of looms for
weaving net-lace and curtains comprising means for delivering bobbins and
shuttles one by one form suitable separated receptacles, means for inserting the
bobbin into the opening of the shuttle, and means for drawing the bobbin-thread
through the shuttle eye and delivering the fed shuttle into a suitable receptacle,
substantially as herein before described.
2. A self-acting machine for inserting bobbins into shuttles of looms for
weaving net-lace and curtains comprising separate receptacles (tubes or guides),
to receive bobbins and shuttles and arranged on the table of the machine, said
receptacles being closed at the lower end by slides C₁ B', guided in the table and
having the same width as the shuttles and bobbins, rotatable cam-discs with
draw-bars and levers adapted to move said slides in such a manner, that a shuttle
is first delivered into an opening of the table and then a bobbin is delivered from
its receptacle into the opening of the shuttle, and a spring tending to press said
bobbin into the opening, substantially as described. .
3. A self-acting machine for inserting bobbins into shuttles of looms, for
weaving net-lace and curtains comprising an arrangement for drawing back the
friction spring of the shuttle to allow the bobbin completely to enter the shuttle
opening and for feeding the thread through the shuttle eye, the arrangement
consisting of a slide D₁, a lever E' driven and raised by a rotatable eccentric,
a hook E on the end of the same passing through an eye L of the shuttle, a stop
or pin E2 upon the lever E', a spring R₁ attached to the slide D¹, operated by 13
and a nose or pin n on the spring passing through an opening of said slide in
front of the friction spring and operating it, the action of the parts allowing
the fed shuttle to drop on to a rail, or into a suitable spout to be delivered to a
receptacle, substantially as described.
4. In a self-acting machine for inserting bobbins into shuttles of looms for
weaving net-lace and curtains, an arrangement for ensuring the feeding of the
bobbin thread through the shuttle eye, consisting of spout or tubes, as receptacles
for the bobbins and, shuttles, provided with longitudinal slots, through which
the ends of the shuttle threads project outwardly, a push J, driven by a lever and
a rotatable cam-disc, to force the thread towards the hook, so that when the latter
is moved back through the shuttle eye, it is compelled to take the thread along,
substantially and for the purpose as described.
