IMPROVED MECHANISM FOR CUTTING OR TRIMMING THE EDGES OF KNIT AND OTHER FABRIC ADAPTED TO SEWING MACHINERY
Year: 1884

page_text: I, ALFRED GEORGE BROOKES of 55 Chancery Lane in the County of Middlesex
Fellow of the Institute of Patent Agents do hereby declare the nature of my
invention for IMPROVED MECHANISM FOR CUTTING OR TRIMMING THE EDGES OF
KNIT AND OTHER FABRIC ADAPTED TO SEWING MACHINERY to be as follows:-
This invention has reference to mechanism for trimming the edge of knit fabrics
while being sewed by a sewing machine, either especially adapted or of ordinary
construction and although being especially designed for trimming knit fabrics can
be used on various other material.
The invention consists in the combination with an organized sewing mechanism
of two cutting discs rotated positively and in unison by gearing, and their shafts
placed at an angle with relation to each other, whereby the edge of one disc is
enabled to pass the edge of the other disc, and a spring to keep the edges of the
dises together, the two discs having a common cutting point located at a point
substantially diametrically opposite the needle and stitching point, whereby the
stitching and cutting operations are essentially simultaneous and the discs kept
sharp.
Also in a sewing machine a rotating cutting disc having its face arranged
substantially parallel with relation to the acting face of the feed or the work
support, and a second rotating disc having its face set at an angle with relation to
aforesaid disc, combined with the presser foot and the smoother adapted to bear
upon the material above the second disc.
Also, in the combination with stitch forming mechanism in a sewing machine, of
a rotating cutting disc adapted to rotate in a plane substantially parallel with the
acting face of the feed or the face of the work support, a second rotating disc
adapted to rotate in a plane angular thereto, an attachment frame to support the
shafts of the said dises and means to adjust the said frames horizontally while the
machine is in operation.
Also in the combination with stitch forming mechanism in a sewing machine, of
a rotating cutting disc adapted to rotate in a plane substantially parallel with the
acting face of the feed or the face of the work support, a second rotating diso

page_text: adapted to rotate in a plane angular thereto, an attachment frame to support the
shafts of the said discs, and means to adjust the said frame backwards and forwards
with relation to the feed of the material.
Also, in the combination with stitch forming mechanism in a sewing machine of
a rotating cutting disc adapted to rotate in a plane substantially parallel with the
acting face of the feed or the face of the work support, and a second rotating disc
adapted to rotate in a plane angular thereto, an attachment frame to support the
shafts of the said discs, and means to adjust the, said attachment frame both laterally
and lengthwise with relation to the direction of the feed.
Also, in the combination with the stitching mechanism of a sewing machine, of a
rotating disc, having its face arranged, substantially parallel with the cloth support,
a second cutting disc having its face placed at an angle thereto, and an attachment
frame supported above the cloth plate leaving a space between the trimming
mechanisin and the cloth plate.
Also, in a sewing machine, the combination with stitching mechanism, and two
rotating cutters having their faces placed at an angle with relation to each other,
of a presser foot and a smoother to hold at both sides of the upper cutter the
material being sewed and trimmed.
Also, in a stitch forming mechanism of a sewing machine, combined with two
cutting discs, and means to positively rotate them, the said dises having their faces
inclined with relation to each other, and having a common cutting point located at
a point substantially diametrically opposite the needle and stitching point, and in
close proximity thereto, whereby the stitching and cutting operations are essentially
simultaneous.
Also in a stitching mechanism and cloth plate or support, and attached lifting
plate, combined with the attachment frame and its two rotating cutting discs
arranged as will be described with relation to each other, and the cloth plate.
Also in a sewing machine combined with a trimming mechanism for attachment
thereto, the latter comprising two cutting discs, and means to positively rotate each,
one of such discs having its face substantially parallel with relation to the acting
face of the feed or work support, while the face of the other disc is arranged at an
angle thereto, so that the meeting edges of such disc constitute a common cutting
point located at a point substantially diametrically opposite the needle and stitching
point, where the stitching and cutting operations are essentially simultaneous.
Supposing for the sake of illustration that the frame-work, needle actuating arm,
needle bar, presser bar, and rotating hook shaft, and cloth plate or support, are all
as in the Willcox and Gibbs machine.
Upon the presser bar is applied the presser foot it having projecting from one end
of it the smoother either a rigid or elastic arm the underside of which is sufficiently
high to rest upon the material above that one of the cutting discs the face of which
is parallel with the acting face of the feed or the work support while the under portion
of the main part of the said presser foot rests upon the material above the regular
cloth plate of the machine.
This smoother when it is in its lowest position will descend upon the material
resting between it and the face of the disc smoothing or pressing upon the said
material as the usual feeding device retires from engagement therewith and while
the cutting discs are at rest and the usual needle is in the material.
The hook shaft has attached to it a suitable cam which acts upon a lever or arm
having a suitable pawl which engages a ratchet fast on the main shaft of the
trimming attachment, the said cam and pawl and ratchet imparting to the said shaft
an intermitting motion of greater or less extent according to the length of stroke it
is desired to impart to the cutters, that being in proportion to the length of feed,
but instead of the particular pawl and ratchet shown a friction pawl mechanisin of
any usual and suitable construction may be employed and any usual means may be
employed to move the arm a greater or less distance and consequently turn the
main shaft more or less at each rotation of the book shaft.
A detent prevents retrogade movement of the main shaft.

page_text: The shaft has its bearing in suitable ears of the attachment frame it having a
back wardly extended arm and a cap or cover making a box like head to enclose the
gearing to be described.
The cap is attached by screws.
The end of the main shaft is provided with a bevel gear having a bevel gear
attached to it. The gear engages another gear fast on an inclined shaft having its
bearings in the attachment frame and provided at one end with a cutting disc the
face of which is set at an inclination with relation to the face of the cutting disc
which is attached to the lower end of a shaft which also has its bearings in the
said attachment frame, both of the said discs being made movable bodily with the
said frame.
The lower end of the inclined shaft opposite that carrying the cutting disc is
surrounded by a spring and has one or more nuts attached to it so that the said
spring acts to normally draw the said shaft longitudinally and keep the cutting
edges of the disc in proper cutting position with relation to the edge of the
co-operating cutting disc thus enabling the two edges of the said cutters to always
operate together properly notwithstanding wear, and materially aid in keeping the
cutting edges of the discs in good working order.
"
As the cutting disc shafts cross each other the edges of the one disc would
apparently not come into the proper place with relation to the edge of the other
disc, but as the one disc drops slightly below the cutting edge of the other disc, the
cutting edges of the two discs are brought in such position that the edge of the one
comes to the edge of the other in its central line.
A spring keeps the edge of the one disc against the edge of the other disc, and
as heavy material requires greater power to cut it than light material, the pressure
between the discs may be properly varied by adjusting nuts thus more or less
compressing the spring.
The one cutting disc shaft derives its motion of rotation from bevel gear which
engages bevel gear fast on the said shaft.
An arm of the attachment frame is slotted and applied in an adjustable manner
upon a screw fastened to the main frame and at opposite sides of the said arin the
said screw is provided with two adjustable nuts, the movement of the said nuts in
the same direction on the screw enabling them to adjust the rear end of the said
arm backward or forward with relation to the shaft, and when such adjustinent is
made screws extended through slots in the adjustable plate, into the attachment
frame will be loosened thus permitting the head part of the said frame to be
adjusted backward or forward in the direction of the feed so as to place the cutting
points of the said discs more or less close to the needle.
The face of the one cutting disc, is parallel or substantially so, with the acting
face of the feed and of the usual cloth plate or the throat plate thereon and for
most of the time the lower end of the shaft will just touch the cloth plate.
The attachment frame is held at the proper height so as to place the said cutting
disc in proper relation to the cloth plate by means of screws inserted through a
plate forming part of a yoke having suitable ears which receives a screw the
threaded shank of which is extended through a threaded hole made in the head of
the machine between the needle and presser bar, the rotation of the said screw by
engaging its head causing the said plate to be moved lengthwise of the machine or
laterally with relation to the needle and the direction of the feed:
During this adjustment of the cutting attachment to trim the material more or
less distant from the line of stitching produced by the needle, the thread, and
sewing parts, the nuts, holding the rear end of the extension are loosened.
This adjustment may be made while the machine is stitching.
The width of cam or eccentric employed is suflicient to enable the cam to always
actuate the lever which is instrumental in moving the main shaft.
In order to raise or lead the material being stitched and trimmed up to the level
of the face of the one cutting disc a lifting plate the edge of which is bevelled is
attached to the usual cloth plate by means of a screw in front of the needle,

page_text: Instead however of this lifting plate the cloth plate might be cut out and the
one cutting disc be placed in it with its upper side or face flush with the cloth
plate.
The one cutting disc may be larger in diameter than the other cutting disc to
gain width for the reception between the,discs of the edge of the material to be
trimmed the space into which the edge to be trimmed off passes being limited it
will be seen, by the diameter of a regulating disc.
A milled wheel on the main shaft permits the cutting discs to be operated by
hand when starting to trim an article or otherwise.
The one cutting disc having been arranged with its face or upper side in proper
position with relation to the cloth plate and acting face of the feed, the face of the
other cutting disc may be more or less inclined with relation to the face of the one
disc at an acute or obtuse angle, but in this latter event its shaft would be extended
downward and be driven from the hook shaft by gearing located below the cloth
plate.
The mechanism for driving the two disc cutters having the described arrangement
with relation to each other and the feed and the cloth work support may be
variously modified according to the sewing machine with which the said discs are
to be employed, and this without departing from my invention.
By raising the one cutting disc sufficiently above the cloth plate to pass beneath
it one part of the material being sewed a single thickness of the said material
beyond the line of stitching joining it with the material extended under the one
dise may be inserted between the discs and be cut off parallel with the seam.
This plan permits the edge of a hem to be cut off.
The smoother instead of being attached to the presser-foot pad may
be pivoted
at some other point on the presser bar and be made adjustable vertically.
The herein described trimming mechanism is adapted for use in connection with
a sewing machine, but it is obvious that the same would operate to cut cloth
etcetera if driven by other mechanism than a sewing machine, and it could be made
to cut fabrics which were not being sewed on a sewing machine.
Dated this 4th day of March 1884.

In the drawing the frame-work A, needle actuating arm A¹, needle bar A²,
presser bar A³, and rotating hook shaft A', and cloth plate or support A6, are all as
in the Willcox and Gibbs machine so need not be herein described.
Upon the presser bar is applied the presser foot a it having projecting from one
end of it the smoother a¹ either a rigid or elastic arm the underside of which is
sufficiently high to rest upon the material above that one of the cutting disks b the
face of which is parallel with the acting face of the feed 6° or the work support
while the under portion of the main part of the said presser foot rests upon the
material above the regular cloth plate of the machine.
This smoother (shown elevated, the presser foot being lifted in Figures 1 and 2,)
when it is in its lowest position will descend upon the material resting between it
and the face of the disk b, smoothing or pressing upon the said material as the
usual feeding device retires from engagement there with and while the cutting disks
are at rest and the usual needle is in the material.
The hook shaft A4 has attached to it a suitable cam c which acts upon a lever or
arm c¹ having a suitable pawl which engages a ratchet c² fast on the main shaft d
of the trimming attachment, the said cam and pawl and ratchet imparting to the
said shaft an intermitting motion of greater or less extent according to the lengtli

page_text: of stroke it is desired to impart to the cutters, that being in proportion to the
length of feed, but instead of the particular pawl and ratchet shown a friction paw!
mechanism of any usual and suitable construction may be employed and any usual
means may be employed to move the arm c¹ a greater or less distance and conse-
quently turn the shaft & more or less at each rotation of the hook shaft.
The detent 8 prevent retrograde movement of the shaft d.
The shaft d. has its bearing in suitable ears d' of the attachment frame d³ it
having a backwardly extended arm d³ and a cap or cover d' making a box like
bead to enclose the gearing to be described.
The cap is attached by screws 2.
The end of the shaft d is provided with a bevel gear e having a bevel gear el
attached to it. The gear e engages a gear f fast on an inclined shaft 3 having its
bearings in the attachment frame and provided at one end with the cutting disk g
the face of which is set at an inclination with relation to the face of the cutting
disk b which is attached to the lower end of a shaft 6 which also has its bearings
in the said attachment frame, both of the said disks being made movable bodily
with the said frame.
The lower end of the shaft 3 opposite that carrying the cutting disk gis
surrounded by a spring gl and has one or more nuts g² attached to it so that the
said spring acts to normally draw the said shaft longitudinally and keep the cutting
edges of the disk g in proper cutting position with relation to the edge of the
cooperating cutting disk b thus enabling the two edges of the said cutters to -
always operate together properly notwithstanding wear, and materially aid in
keeping the cutting edges of the disks in good working order.
As the shafts 3 and b' cross each other the edges of the disk g would apparently
not come into the proper place with relation to the edge of the disk, but as the
disk g drops slightly below the cutting edge of disk b, the cutting edges of the two
disks are brought in such position that the edge of g comes to the edge of disk b.
in its central line.
The spring g' keeps the edge of disk g against the edge of disk b, and as heavy
material requires greater power to cut it than light material, the pressure between
the disks may be properly varied by adjusting the nuts g2 thus more or less
compressing the spring g'.
The shaft b¹ derives its motion of rotation from the bevel gear e¹ which engages
the bevel gear 62 fast on the said shaft.
The arm d³ of the attachment frame is slotted and applied in an adjustable
manner upon a screw h fastened to the frame A, and at opposite sides of the said
arm the said screw is provided with two adjustable nuts h, h³, the movement of
the said nuts in the same direction on the screw enabling them to adjust the rear
end of the said arm backward or forward with relation to the shaft A, and when
such adjustment is made the screws 6, 6, extended through slots 16 in the
adjustable plate i, into the attachment frame will be loosened thus permitting the
head part of the said frame to be adjusted backward or forward in the direction
of the feed so as to place the cutting points of the said disks more or less close to
the needle.
The face of the cutting disk b, is parallel or substantially so, with the acting
face of the feed and of the usual cloth plate or the throat plate thereon and
for most of the time the lower end of the shaft b¹ will just touch the cloth
plate A6.
The attachment frame is held at the proper height so as to place the said cutting
disk in proper relation to the cloth plate by means of the screws 66 inserted
through the plate i forming part of a yoke m having suitable ears m', m², which
receives a screw m³ the threaded shank of which is extended through a threaded
hole made in the head of the machine between the needle, and presser bar, the
rotation of the said screw by engaging its head m* causing the plate i to be moved.

page_text: rengun wise of the machine or faterany with relation to the needle and the direction
of the feed.
During this adjustment of the cutting attachment to trim the material more or
less distant from the line of stitching produced by the needle, the thread, and
sewing parts, the nuts h¹, h², holding the rear end of the extension d³ are
loosened.
This adjustment may be made while the machine is stitching.
The width of cam or eccentric e is sufficient to enable the cam to always actuate
the lever c¹ which is instrumental in moving the shaft d.
In order to raise or lead the material being stitched and trimmed up to the level
of the face of the cutting disk ba lifting plate n¹ the edge of which is bevelled is
attached to the usual cloth plate by means of a screw n in front of the needle.
Instead however of this lifting plate the cloth plate might be cut out and
the cutting disk b be placed in it with its upper side or face flush with the cloth
plate.
The disk bis herein shown as larger in diameter than the disk g to gain width
for the reception between the disks of the edge of the material to be trimmed the
space into which the edge to be trimmed off passes being limited it will be seen, by
the diameter of the disk 7.
The milled wheel o on the shaft & permits the cutting' disks to be operated by
hand when starting to trim an article or for any other purpose desired.
The disk b having been arranged with its face or upper side in proper position
with relation to the cloth plate and acting face of the feed, the face of the disk g
may be inore or less inclined with relation to the face of the disk b, as for instance
it may be arranged at an acute as in Figures 1 to 8, or may be at an obtuse angle
as shown in Figure 11, but in this latter event the shaft b would be extended
downward and. be driven from the hook shaft by gearing located below the cloth
plate.
arrangement
The mechanism for driving the two disk cutters having the described.
with relation to each other and the feed and the cloth work support may be
variously modified according to the sewing machine with which the said disks are
to be employed, and this without departing from my invention.
By raising the disk b sufficiently above the cloth plate to pass beneath it one
part of the material being sewed a single thickness of the said material beyond the
line of stitching joining it with the material extended under the disk b may be
inserted between the disks and be cut off parallel with the seam.
This plan permits the edge of a hem to be cut off.
Two disks or circular knives arranged at the ends of two horizontal shafts have
been used to cut different materials and to cut cloth or other material for hat work,
but in no instance have two cutting disks been arranged to trim materials parallel
with an irregular or curved line of stitching being made.
Two rotating cutting disks attached to horizontal shafts such as heretofore
employed cannot be combined with a sewing mechanism to cut or to trim the edge
of material closer to the seam or line of stitching, and as the seam is being made
in curved or irregular lines.
Also a single cutting disk having a truly circular cutting edge, and a single disk
having an irregular edge ha been used to trim material close to the seam or line
of stitching being made.
The smoother instead of being attached to the presser-foot pad may be pivoted
at some other point on the presser bar and be made adjustable vertically.
The herein described trimming mechanism is adapted for use in connection with
a sewing machine, but it is obvious that the same would operate to cut cloth
et cetera if driven by other mechanism than a sewing machine, and it could be
made to cut fabrics which were not being sewed on a sewing machine.
