MACHINES A Communication to me from abroad by Emile Cornely, of Paris,

"
The subject of the present invention is the application to sewing or embroidering
machines of an automatic cutting apparatus, which cuts the thread of each single
stitch after it has been drawn by the needle above the cloth, thus producing a
velvet or peluche-like surface when the stitches are laid closely together one to
another.
To fully explain the nature of this invention I have represented it on the
drawings as applied to a Bonnaz embroidering machine, which latter being fully
known, does not require any description, but it may equally well be applied to
any system of sewing or embroidering machines
Figure 1-represents this improved cutting apparatus as applied to a Bonnaz
embroidering machine
Figure 2-represents the said apparatus in full size secured to the head plate of
the machine
Figures 34 and 5 are detached views hereafter to be referred to
A grooved cam B is secured to the mainshaft A. of the machine, and imparts-by
its rotation a reciprocating motion to the lever C, which is pivoted at D, to the
frame of the machine. The lower end b of the lever C is slotted and imparts a
reciprocating motion to the slide d, which plays within the block E, which latter
is secured to the head plate G. of the machine by means of the screw H.

page_text: The slide d is supported by means of the studs g and h, which are screwed into
the block E and it is provided with suitable slots 2 and 3 through which the
studs g and h pass
Two plates m and o. are sustained by the stud h and can swing on said stud as
their centre, they are provided by two inclined slots q, r, through which passes the
stud which is screwed to the slide d, it is provided with a friction roller 4 which
is fitted within the slots q, r,-Two cutting blades p are secured to the perpendicular
arms of the plates m, o
The reciprocating motion of the lever C imparts a rectilinear reciprocating
motion to the slide d, to its stud u and its friction roller 4 which acting against
the inclined sides of slots q, 7, of the arms m, o, opens and closes those latter and
consequently the cutting blades p at each. stitch of the machine which thus
constitute a pair of cutting scissors which are operated mechanically
The groove on cam B is adjusted in such a manner that the scissors p close up
when the thread has been drawn above the cloth and they thus cut it in said
position (fig: 5) below the needle; and when the needle and the nipple v commence
their descending motion, they open (fig: 4) to allow them a free passage
downward.
The cutting blades p are secured to the vertical parts of plates m and o by means
of screws and they can easily be removed and replaced when they are to be
changed or to be sharpened
It is evident that the automatic cutting of the thread of each stitch can be
executed also by other means than by the scissors above described, such as recipro-
cating or rotary cutters, which may be operated by mechanical means so as to cut
the thread at the moment when it shall have been drawn above the cloth, I
therefore do not limit my invention to the sole application of scissors nor to the
manner of operating them by the devices above explained

by the said Williain Edward Gedge in the Patent Office on the 5th January

WILLIAM EDWARD GEDGE of N° 11 Wellington Street, Strand London, in the
County of Middlesex, Patent Agent, "IMPROVEMENTS IN SEWING OR EMBROIDERING
MACHINES A Communication to me from abroad by Emile Cornely of Paris,
France.
"
The object of the present invention is the application to sewing and embroidering
machines of a mechanical cutting apparatus, which cuts each stitch of the machine
singly after its thread has been drawn by the needle above the cloth, thus
producing a a velvet or peluche like surface when the stitches are laid sufficiently
close together one to another.
To fully explain the nature of this invention I have represented it on the
drawings as applied to a "Bonnaz" embroidering machine, which, being fully
known, does not require any description; but it may be applied in combination
with any sewing machine.
Figure 1. represents the cutting mechanism applied to the head of a "Bonnaz"
embroidering machine.
Figure 2. represents the said mechanism in full size as secured to the head plate
of the machine.
Figures 3, 4, and 5 represent detached views hereafter to be explained.
A grooved cam B, is secured to the main shaft A, of the machine and imparts
by its rotation a reciprocating motion to the lever C, which is pivoted at D, to the
frame of the machine. The lower end b of the lever C, is slotted and imparts a
reciprocating motion to the slide d, which plays within the block E, which latter
is secured to the head plate G, of the machine by means of the screw H. The
slide d is supported by means of the studs g, and h, which are screwed into the
block E, and it is provided with suitable slots 2 and 3 through which the studs h,.
and g, pass.
Two plates m, and o, are sustained by the stud h, and can swing on said stud as
their centre, they are provided with two inclined slots q, and r, through which
passes a stud u, which is screwed into the slide d, and which is provided with a
friction roller 4, which is fitted within the slots q, and r. Two cutting blades p
arc secured to the vertical arms of the plates m and o.
The reciprocating motion of the lever C, imparts a rectilienear reciprocating
motion to the slide d, and to the stud u, which plays within the inclined slots q,
and r, of the arms m, and o; thus the latter and consequently their cutting blades p
are opened and closed at each stitch of the machine, and thus consitute [sic] a pair
of cutting scissors which are operated mechanically.
The groove in cam B is adjusted in such a manner that the scissors p, close up
when the needle has drawn its thread above the cloth and they thus cut it in said
position (fig: 5); and when the needle and its nipple v, commence their downward
movement they open to allow them a free passage (fig: 4)
The cutting blades p are secured to the vertical arms of the plates m, and o, by
means of screws and can be easily replaced and be removed when they are to be
changed or to be sharpened.
It is evident that the mechanical cutting of each stitch of the machine can be
executed also by other means than by the scissors above explained, such for
instance as reciprocating or rotary cutters which are also actuated by mechanical
means to cut the thread of each stitch after it shall have been drawn above the

page_text: th. I therefore do not limit my Invention to the sole application of scissors
to the manner in which they are operated.
Having now described and ascertained the Nature of. the Invention Communi-
ed to me as aforesaid and in what manner the same is or may be performed.
[ Claim as secured to me by the hereinbefore in part recited Letters Patent :-
Cutting by mechanical means the thread of a sewing or embroidering
machine at each stitch and after each stitch shall have been drawn above
the cloth.
°
2° The application of a mechanical cutting apparatus below the needle of a
sewing or embroidering machine for the purpose of cutting each stitch after
its thread shall have been drawn above the cloth.
3° In combination with a sewing or embroidering machine the scissors shown
and described, when operated by mechanical devices for cutting at each
stitch the thread of the machine.
-Operating the scissors which are applied below the needle of a sewing or
.embroidering machine by means of a system of levers and slides actuated
directly or indirectly from the main shaft of the machine.
In witness whereof I the said William Edward Gedge have hereunto set my
d and scal this Fifth day of January in the year of our Lord One thousand
ht hundred and Eighty four
