PROVISIONAL SPECIFICATION.
Cutting Apparatus Applied to Embroidering Machines.
We, EMILE CORNELY and. ROBERT CORNELY, of 87 Faubourg St. Denis,
Paris, France, Manufacturers of Sewing Machines do hereby declare the nature of
this invention to be as follows:-
The apparatus hereafter described is employed for cutting the upper layer of
cloth according to the ornamental embroidery seams by means of which the said
layer has been sewn unto an under layer of cloth. The machine which is employed
for this purpose is substantially the same as the one which is known as the Bonnnz
embroidering machines and on which such modifications have been made that it will
execute the cutting work above described.
On the accompanying drawings:-
Figure 1 represents the head plate of the machine arranged in such a manner.
that the machine will execute the cutting alone without making the embroidering
seam.
Figures 2 and 3 represent the cutting tool on an enlarged scale.
Figure 4 represents the head plate when the machine is arranged to execute the
einbroidering seam and the cutting of the cloth at the same time.
In Figure where the organs for sewing do not exist on the machine there
remain only the organs' of the universal feed, a, b, c, d, e, and the feed surface m
which can all be turned by the crank handle of the machine by means of the
pinions f, 9 and shaft so that the feeder m will feed the cloth in any direction
without turning it by hand: As, said organs and their operation are fully known a
description thereof is not necessary. For the cutting operation the tube B is fixed
and is thus prevented from moving up and down and a kuite C is secured in the
screw nut n of tube B and is fixed therein by means of the screw 2. The height
of the knife C is adjusted in such a manner that its point will pass through the
upper layer 3 of the cloth but will not reach the under layer 4. This being done,
the machine is set in motion and as the feeder m pushes the cloth against the
cutting edge of the knife C the latter cuts the upper cloth at each turn of the
machine-the length of the feeds stroke; and as the tube B to which the knife Cis
secured turns also with tube e and with all the organs of the universal feed it
follows that the knife C is also directed by the crank handle and turns in con-
formity with the feed thus cutting the cloth in any direction by the action of the
crank handle.
It is necessary that the height of knife C should be adjusted with great accuracy..
For this purpose the collar p of the tube B is provided with a projection 5 through
which passes a sorew D which turns within a supporting piece Eland by turning its
button H the knife: Cwill he raised or lowered and can be adjusted with great
accuracy.

which presses on the material. In this case the knife is fixed on the sleeve M

plate N which extends into the collar q of the sleeve M, said forkediplate N being
secured to the head plate by means of screw D
The sleeve Meturns with. the tube B, by the pin 6 of said tube playing freely
within a slot in sleeve M when the tube Brises and descends and as the tube B

page_text: turns in conformity with the universal feed the knife C follows the same motion
and cuts the cloth alongside the nipple and close to the embroidery which is
executed by the machine so that in this case the operations of embroidering and
of cutting the cloth are performed at the same moment. The knife C being fixed
the cutting operation is performed by the feed only of the cloth against the cutting
edge of the knife and thus all operating parts in the cutting tool are avoided.
The cutting tool can be made very thin thus the cloth can be cut very close to
the seam and the knife can follow the most intricate designs and can enter even
into the closest angles.

Cutting Apparatus Applied to Embroidering Machines.
We, EMILE CORNELY and ROBERT CORNELY of 87 Faubourg St. Deuis,
Paris, France, Manufacturers of Sewing Machines, 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 :-
The apparatus hereafter described is employed for cutting the upper layer of
cloth according to the ornamental embroidery seams by means of which the said
layer has been sewn unto an under layer of cloth. The machine which is employed
for this purpose is substantially the same as the one which is known as the
Bonnaz embroidering machine and on which such modifications have been made,
that it will execute the cutting work above described.
Upon the accompanying drawings,
Figure 1. represents the hend plate of the machine arranged in such a manner
that the machine will execute the cutting alone without making the embroidering
Beam.
Figures 2 and 3 represent the cutting tool on an enlarged scale.
Figure 4 represents the lead plate when the machine is arranged to execute
the embroidering seam and the cutting of the cloth at the same time.
In Figure where the organs for sewing do not exist on the machine, there
remain only the organs of the universal feed a bede and the feed surface m
which can all be moved by the crank handle of the machine by means of the
pinions fg and shaft so that the feeder will feed the cloth in any direction
without turning it by hand. As said organs and their operation are fully known
a description thereof is not necessary. For the cutting operation the tube B is
held by a collar p and is thus prevented from moving up and down and a knife C
is secured in the screw nut of the tube B and is fixed therein by means of
the screw 2. The height of the knife C is adjusted in such a manner that its point
will pass through the upper layer 3 of the cloth but will not reach the under layer 4.
This being done the machine is set in motion and as the feeder m pushes the cloth
against the cutting edge of the knife C the latter cuts the upper cloth at each turn
of the machine the length of the feed stroke; and since the tube B to which the
knife C is secured turns also with tube e and with all the organs of the universal
feed, it follows that the knife C is also directed by the crank handle and turns in
conformity with the feed thus cutting the cloth in any direction by the action of
the crank handle.
It is necessary that the height of knife C should be adjusted with great accuracy.
For this purpose the collar of the tube B is provided with a projection 5 through
which passes a screw D which turns within a supporting piece E and by turning

page_text: its button H the knife C will be raised or lowered and can be adjusted with great
accuracy.
Figure 4 represents the head plate provided with all the organs of the universal
feed as well as those for embroidering, such as the needle-bar O and the nipple r
which presses on the material. In this case the knife is fixed on the sleeve M
which is set on the nipple tube B but which is held rigidly against vertical move-
inent by means of the forked plate N which extends into the collar 7. of sleevo M,
said forked plate N being secured to the head plate by means of screw D.
The sleeve M turns with the tube B by the pin 6 of said tube playing freely
within a slot in sleeve M when the tube B rises and descends and as the tube B
turns in conformity with the universal; feed, the knife C follows the same motion
and cuts the cloth alongside the nipple and close to the embroidery which is
executed by the machine so that in this case the operations of embroidering and
cutting the cloth are performed at the same moment. The knife C being fixed the
cutting operation performed by the feed only of the cloth against the cutting
edge of the knife and thus all operating parts in the tool are avoided.
The cutting tool can be made very thio, thus the cloth can be cut very close to
the seam and the knife can follow the most intricate designs and can enter even
into the closest angles.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is,
1. Cutting apparatus for embroidering machines comprising a universal feed
motion furnished with a fixed knife capable of being turned and operated by a
crank handle movement, the whole arranged in such a manner that the material is
pushed against the cutting edge of the kuife by means of the feed mechanism at
each revolution of the machine substantially as described, and illustrated upon the
accompanying sheet of drawings.
2. The screw adjustment for securing the requisite height of the knife.
substantially as and for the purposes described.
