"
MORITZ LÖB, of the Firm Nathan Löb and Söhne, at Berlin, Kingdom of Prussia,
Empire of Germany. A NEW OR IMPROVED CUTTING-OUT ATTACHMENT APPLICABLE
TO THE BONNAZ' EMBRODERING MACHINE, SO AS TO EMBROIDER AND CUT OUT
SIMULTANEOUSLY."
The object of this Invention is to provide a cutting-out attachment for embroidering
machines of the "Bonnaz" class, so that the cutting out of the waste material shall
be effected and take place simultaneously with the embroidering of the design.
The embroidering machine Bonnaz is so well known and extensively used as to
render it unnecessary to describe the different parts of it in setting forth these
improvements. The great advantage of this machine as compared with all known
sewing machines, that is, to embroider by means of the crank the most complicated
designs without guiding the cloth after the same, is left unaltered in the application
of this Invention.
All acquainted with the art will be aware of the great loss of time and
expensiveness of the process of cutting out by hand of the waste material after the
einbroidering has been effected, which cutting out has heretofore been the only
possible process, and especially expensive and troublesome when the object is large,
such as tuelle lace curtains and the like, apart from the finer and more uniform
execution effected by this Invention.
The apparatus is attached to the machine and the working thereof remains in all
respects the same, except that simultaneously with the usual embroidering action
the cutting out takes place, and the improved apparatus is actuated to effect such
cutting out.
The apparatus consists of a strong ring turned out of one piece of cast steel and

page_text: secured upon and around the central stem, and to said ring is attached by two
screws a bracket, to which bracket the shears are jointed. A link piece is jointed
at one end to the extremity of the upper blade of the shears and at its other end to
the central stem, so that upon the embroidering taking place through the said
central stem the shears by the link will be correspondingly actuated. A cloth 5
presser of larger size than ordinarily used in these machines is employed, and the
shears work therein as in a guide, and have play in all directions, following the
course of the needle so as to cut away the waste material.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Moritz Löb in the Great Seal Patent Office on the 19th July
1877.
MORITZ LÖB, of the Firm of Nathan Löb and Söhne, at Berlin, Kingdom of Prussia,
Empire of Germany. "A NEW OR IMPROVED CUTTING-OUT ATTACHMENT APPLICABLE
TO THE BONNAZ EMBROIDERING MACHINE, SO AS TO EMBROIDER AND CUT OUT
SIMULTANEOUSLY."
The object of this Invention is to provide a cutting out attachment for embroidering
machines of the "Bonnaz" class, so that the cutting out of the waste material shall
be effected and take place simultaneously with the embroidering of the design.
The embroidering machine "Bonnaz" is so well known and extensively used as to
render it unnecessary to describe the different parts of it in setting forth the
improvements. The great advantage of this machine, as compared with all known
sewing machines, that is, to embroider by means of the crank the most complicated
designs without guiding the cloth after the same, is left unaltered in the application
of this Invention.
All acquainted with the art will be aware of the great loss of time and
expensiveness of the process of cutting out by hand of the waste material after the
embroidering has been effected, which cutting out has heretofore been the only
possible process, and is especially expensive and troublesome when the object is
large, such as tuelle lace curtains and the like, apart from the finer and more uniform
execution effected by this Invention.
The cutting-out device is attached to the machine and the working of the latter
remains in all respects the same, except that simultaneously with the usual
embroidering action the cutting out takes place, and the improved apparatus is
actuated to effect such cutting out.
The attachment or device consists of a strong ring turned out of one piece of
cast steel, and secured upon and around the central stem, and to said ring is attached
by two screws a bracket, to which bracket the shears are jointed or the lower blade
thereof. The upper blade of the shears is affixed directly or jointed by a link piece
to the needle bar, so that upon the embroidering taking place the shears through
the said needle bar and by the link will be correspondingly actuated.
In order that the said Invention may be clearly understood I have hereunto
annexed a Sheet of Drawings illustrative thereof, and have marked the same with
Figures of reference.
Fig. 1 is an elevation of the embroidering part of an ordinary "Bonnaz "
machine.
Fig. 2, a like view with the inproved cutting-out device attached.
Fig. 3, view of cutting-out device attached, and Fig. 4, a like view of a modifi-
cation, the arrangement shown in Figs. 2 and 3 being direct acting, and that shown
in Fig. 4 being actuated by link from the needle bar.
The part figured 1 in Figs. 2, 3 and 4 is turned out of a piece of cast steel so as
to fit upon or around the lower part of the central stem or tube of the machine, and
is secured thereto, and to this ring piece is attached the lower part 2 of the cutting-
out apparatus, that is, the lower blade of the shears.

page_text: The part figured 3 is the upper blade of the shears,, shown in Figs. 2 and 3
attached directly to the needle bar, and in Fig. 4 shown jointed to the part 2 and
linked by a link piece to the needle bar.
The part figured 4 in Figs. 2 and 3 is a small hammer piece fixed by two screws
to the needle bar along with the upper blade 3 of the shears and screws to press
down the waste material being cut away, and to prevent such waste material
becoming entangled with the needle or other working parts and fouling the
work.
"
The part figured 5 is a cloth presser or presser foot ," of larger size than that
ordinarily used, which "
presser foot" serves as a guide for and wherein the shears
have play in all directions following the course of the needle, the point of the lower
blade of the shears being first inserted in the material so as to cut away the waste
portion thereof.
Having now described the nature and particulars of my said Invention and the
manner in which the same is to be or may be carried into practice, I claim, in a so
called cutting out attachment for an embroidering machine, a pair of shears actuated
from the going part of such machine to cut out the waste material as the
embroidering is effected, constructed and working substantially as shown by the
Drawings and as set forth.
In witness whereof, I, the said Moritz Löb, have hereunto set my hand and
seal, this Fourteenth day of June, One thousand eight hundred and
seventy-seven.
