Southampton Buildings London "IMPROVEMENTS IN EMBROIDERING APPARATUS
FOR SEWING MACHINES." [A communication from abroad by Franklin Howard
Chilton, of the City and State of New York, United States of America.]
This Invention relates to improvements in embroidering apparatus for attachment
to sewing machines and consists in the construction and arrangement of devices
hereinafter described.
The chief object of the said Invention is to produce a simplified form of
embroiderer which can be sold at a minimum price and which may be easily
understood and used by the unskilled operator. Another very great advantage
that my embroiderer possesses is that its operating parts may be constructed quito
small and pivoted in close relation to the vertical line of centre of the sewing
needle, whereby the thread is prevented from vibrating to any great extent, and as
a consequence, no difficulty is experienced in using any kind of silk. By arranging
the parts of my embroiderer according to my Invention the path of the sewing
needle is left unobstructed at all times.
In carrying the said Invention into practice I provide upon the right hand side
of the upper portion of the presser foot an arm which is rigidly affixed and extends
rearward and has pivoted in its extremity a rocking angular lever consisting of a
vertical arm and a horizontal arm; its bearing being at the junction of the two
arms. In the lower end of the vertical arm is pivoted the rear end of a connecting
rod, which extends forward a proper distance and is pivoted at its front end to a

page_text: hub forming part of a swinging hook. This hook is in the form of a half circle, or
half of an ellipse, and is bowed to the right, its rear end is pivoted upon the lower
portion, and slightly to the left of the vertical centre of the presser-foot, its front
end being free and notched or hooked upon its vertical edge. Upon the pivot
which acts as a bearing for the hook is mounted at about its central portions a
swinging bar having a thread eye in its forward end and having pivoted in its rear
extremity one end of an arm, the other end of which is pivotally secured upon the
connecting rod. In the lower portion of the presser-foot is an opening in which
the needle is moved and which is of such size that the embroidering stitch may be
seen while it is being formed.
Upon the front edge of an opening to the right of the vertical line of centre of
the presser-foot is provided a fixed laying hub or thread-detainer.
In the forward end of the angular lever is supplied a suitably formed slot in
which the head of the screw securing the needle in the needle bar of an ordinary
sewing machine is placed, whereby, when the machine is in motion, the lever is
given a rocking movement on its bearing by the vertical action of the needle-bar
In lieu of the fixed laying hub or thread detainer I may employ a movable arm
or device which will answer effectually all the functions of the said hub.
In case I should dispense with the fixed laying device or thread detainer I should
prefer to employ a hook or arm somewhat similar and bowed in a different direction
to the aforesaid hook-and-this-hook-or-arm-would have a swinging movement simul-
taneously with, and towards, the said hook so as to carry the thread to the position
in which it is held by the laying device
According to a modification of my attachment I employ a fixed laying hub and
move the bar by a connection with the hook
The vibrating eye bar may receive its motion, if desired, from some other part of
the attachment than the hook. In some cases the bar is pivotted to an arm and
takes its motion from the rocking lever.
According to another modification I provide an embroiderer in which each stitch
of the embroidering is formed in rear of the sewing needle and sewed down before
another is made
In this case the presser foot has upon one side a plate which extends rearward
and has pivotted in its extremity a shoe. In the shoe is cut a recess forming at its
upper and lower ends, arms. Upon the outer face of the lower arm is secured, by a
set-screw, a plate which may be adjusted vertically at will, according to circum-
stances. In some cases the plate will not be required but with it the attachment
may be applied to, and successfully operated upon, almost any sewing machine. In
the shoe is cut a circular aperture against which is placed a swivel consisting of a
circular plate having lips which turn inward and are bent against the edges of the
circular aperture whereby the swivel is held in place, but at the same time permitted
to turn freely against the face of the shoc.
Upon the front portion of the presser-foot is pivotted an angular eye-bar or thread-
carrier one end of which passes through a slot cut in the swivel while the other
end passes downward and then forward and then downward again in proper relation
to, and just above, the front end of the foot where it is supplied with an eye for the
embroidering thread.
The rear end of the shoe is provided with an extension or arm which projects
downward and has pivotted in its extremity the rear end of an arm which extends
forward through a slot formed in the presser-foot, terminating in proper relation to
the front edge thereof. The front end of the arm is formed into a head which is
enlarged to prevent it from passing rearward through the slot in the presser foot
and provided with a notch or catch for the thread. To the right of the catch the
presser-foot is provided with a similar catch in which the sewing needle has the
usual vertical movement.
For the purpose of having the angular arm or thread-carrier serve as a take up,
if desired, I have supplied an eye in the outer extremity of its upper portion through
which the ambraidering thrand is norsed

page_text: According to another modification of my Invention I provide an embroidering
attachment which is effective in its operation but constructed with a view to
cheapness simplicity and perfection in its details. It is constructed as follows that
is to say;
In order to attach the embroiderer to the sewing machine I provide a foot and
standard in one piece and provide a recess, therein for the reception of the presser-
bar of the sewing machine, so that the same may be attached by a clamp screw at
the hole usually provided in such presser-bar for a "quilter
"
By making this foot and standard in one piece instead of being in several
pieces as heretofore, I am able to lessen the cost and avoid the risk of the parts
becoming displaced and I also am able to shape the recess for the presser-bar to
suit different.kinds of sewing machines, and in connection with this standard and
foot I make provision for the introduction of the twisted blade so that the saine
may be inserted or withdrawn, whereas in the embroiderer attachment heretoforo
made the standard was necessarily in two or more parts so that the twisted blade
could be introduced to its place
The foot is hollow and a base plate is applied to the under side of said foot to
rest upon the fabric that is being embroidered, and at the same time cover the
recess that is formed in said foot. Screws inserted from above the presser-foot
serve to hold the base plate to its place at the bottom of the presser-foot.
One
of these screws has an eye at the upper end through which the embroidering cord
passes.
The base plate has a tube rising from its upper surface, and the base plate is
formed of one piece of metal. This tube forms a hollow hub around which the
tubular gear and book revolve and present the embroiderer thread to the
sewing.
In the machines of this general character heretofore built, the tubular hub has
been made separate from the plate and introduced from above into the revolving
hook to hold the same in place and its lower end passed into a hole through the
said plate, the parts being rivetted and soldered together-These are difficult to
make and liable to work loose. By my improvement the cost of manufacture is
lessened, and the parts are rendered very strong and durable; furthermore the
plate is made to cover the recess into which the gear wheel at the bottom of the
twisted blade is placed, so that this gear wheel can be placed upon a square at the
lower end of the twisted blade when the plate has been removed, and the hole in
the foot which receives the cylinder that there is between the gear wheel and the
hook allows such gear wheel and another wheel to be placed in the proper position
relatively to the twisted blade, before the base plate is introduced and secured;
this is a great convenience in adjusting the parts when putting the embroiderer
together. The hook, cylinder, and pinion are in one piece and the pinion is larger
than the cylinder as aforesaid so as to be durable, and the cylinder at the upper
part of the pinion is tapering to fit into the hole in the foot when the hook is
introduced from below into the said foot.
By preference the end of the base-plate is in the form of a half circle to fit into
the recess in which the pinion is introduced: this serves as a guide to the plate
and ensures its proper position.
The twisted blade is similar to that heretofore in use except that the lower end
passes through a cylinder journal and the extreme end is squared and enters the
polygonal hole in the gear-wheel. This cylinder journal has a shoulder which
rests upon the top of the foot and supports the twisted blade while it is being
rotated by a vibrating staple or nut that is moved by, and with, the needle or
needle-bar.
In the form in which these embroiderer attachments have been made, it has been
necessary to make the standard in two parts so that the bracket can be placed over
the journal at the upper end of the twisted blade
In order to allow of the foot, the standard, and the bracket being made in one
piece I shorten the upper end of the blade so that the journal at the upper end

page_text: will pass freely in beneath the bracket, and pass a screw down through the bracket,
said screw having a socket at the lower end for receiving the journal at the top of
the twisted blade.
To secure the embroiderer attachments with facility to the presser-bar I employ
a stud and tubular nut, the screw portion of the stud passing through the standard
and the quilter hole in the presser-bar, and the stud and nut serving to clamp the
standard firmly to the presser-bar. The stud is availed of for connecting the
thread-tension and the guide through which the embroiderer cord passes to
the embroiderer attachment.
This thread tension consists of a plate-spring that is folded so as to come together
near the ends; at this place there is a stud and the extreme ends of the spring plate
diverge. This folded plate is upon an arm that is supported by the stud and there
is a screw stud where the folded spring is connected with the arm, and a nut
serves to regulate the pressure of the ends of the spring against each other and
in so doing determine the detaining friction that is exerted upon the embroiderer
thread that passes between the springs and over the stud.
It is generally preferable to lead the embroiderer thread through a hole at the
bend of the tension spring: thence through between the ends of the spring to the
eye in the staple or nut at the base of the needle and through an adjustable eye
that is clamped to the arm by the screw; thence to the hole or eye upon the
base of the presser foot. This arrangement-ensures-the-proper_withdrawal_of_the_
embroiderer thread so that it is not in the path of the descending needle.

This Invention relates to improvements in embroidering apparatus for attach-
ment to sewing machines and consists in the construction and arrangement of
devices hereinafter described.
The chief object of the said Invention is to produce a simplified form of
embroiderer which can be sold at a minimum price and which may be easily under-
stood and used by the unskilled operator. Another very great advantage that the
said embroiderer possesses is that its operating parts may be constructed quite small

sequence no difficulty is experienced in using any kind of silk. By arranging the
parts of the said embroiderer according to the said Invention the path of the sewing
needle is left unobstructed at all times.
In the accompanying Drawing:
Figure 1 is a plan or top view of a device embodying the said Invention.
Figure 2 is a similar view of part of the same shewing the embroidering thread
in position to form the stich.
Figure 3 is a similar view to Figure 2 shewing the parts in the first position
(being the reverse of that shown in Figure 2) to forin the stitch illustrated in
Figure 6.
Figures 4 and 5 are views of modifications which will be understood from the
description hereinafter presented.
Figure 6 illustrates the form of stitch made by the embroiderer.
Figures 7, 8, and 9 illustrate another modification.
The remaining Figures will be hereinafter described.
two arms.
A indicates the presser-foot of a sewing machine upon the right-hand side of the
upper portion of which is rigidly fixed the arm B which extends rearward and
has pivoted in its extremity the rocking angular lever C consisting of the vertical
arm a and the horizontal arm b its bearing being at or near the junction of the
In the lower end of the vertical arm a is pivoted the rear end of the
connecting rod D which extends forward a proper distance and is pivoted, at its
front end to the hub d forming a part of the swinging hook E. The book E is in
the form of a half circle or half of an ellipse and is bowed to the right; its rear
end is pivoted to the lower portion and slightly to the left of the vertical centre of
the presser foot A its front end being free and notched or hooked upon its vertical
edge. Upon the pivot e which acts as a bearing for the hook E is mounted at
about its central portions the swinging bar F having a thread eye f in its forward
end and having pivoted in its rear extremity one end of the arm the other end
of the arm h being pivotally secured upon the connecting rod D. In the lower
portion of the presser foot A is an opening i in which the needle is moved and
which is of such size that the embroidering stitch may be seen while it is being
formed.
Upon the front edge of the opening i to the right of the vertical line of centre
of the presser-foot, is provided a fixed laying hub or thread detainer m.

page_text: In the forward end of the angular lever C is supplied a suitably formed slot n
in which the head of the screw securing the needle in the needle-bar of an ordinary
sewing machine is placed whereby when the machine is in motion, the lever C is
given a rocking movement on its bearing by the vertical action of the needle-bar.
In the operation of the attachment above described the embroidering thread is
passed from a tension device through the eye f in the vibrating bar F and thence
through the opening i and under the presser foot. The needle-bar is then given
its first downward stroke which has the effect of depressing the lever C by which
the connecting rod D is drawn toward the rear. This rearward movement of the
rod D causes the hook E to swing to the right and toward the rear and the forward
end of the vibrating bar F to move toward the front and to the left, until the
embroidering thread in its eye f is just in front of the notch in the end of the
hook E. The succeeding upward stroke of the needle-bar reverses the movement
of the devices above described, whereby the hook E is caused to swing back to the
front and left carrying the embroidering thread with it while the bar F moves
toward the rear. When the devices are in this position the embroidering thread is
in a diagonal line from the eye f over the end of hook E thence around the said
end in the notch and to the left around the right-hand end of the laying hub m
whence it passes under the presser-foot. The sewing needle now again enters the
fabric.passing between_the_line_of_thread_that_extends from the eye f to the notch
in the hook and that which passes from the point of the hook around the laying
hub. The depression of the sewing needle, causes the connecting rod D to be
drawn toward the rear as before and the ends of the swinging hook E and bar F
to move toward cach other as above described whereby that portion of the thread
which was looped around the point of the hook is drawn around the stitch formed
by the needle. The movement of the hook E and vibrating bar F is positive and
these parts cannot fail to perform their functions with every movement of the
needle-bar. The line of stitches formed are in the contour of a cycloidal line and
each loop is sewed to the fabric as fast as made.
In
In lieu of the fixed laying hub or thread detainer m I may employ a movable
arm or device which will answer effectually all the functions of the hub m.
case I should dispense with the fixed laying device or thread detainer m I should
prefer to employ a hook or arm somewhat similar and bowed in a different
direction to the hook E and this hook or arm would have a swinging movement
simultaneously with and towards the hook E so as to carry the thread to the
position in which it is held by the laying device, in Figure 2.
In Figure 5 is shewn another modification of the said attachment in which I
employ a fixed laying hub m and move the bar F by a connection with the hook E.
The vibrating eye-bar F may receive its motion if desired from some other part of
the attachment than the hook E. In Figure 4 is shewn a modification wherein
the bar F is pivoted to an arm and takes its motion from the rocking lever C.
In Figures 7, 8 and 9 are illustrated different views of a modified form of
embroiderer in which each stitch of the embroidering is formed in rear of the
sewing needle and sewed down before another is made. A denotes the presser-foot
having upon one side a plate B which extends rearward and has pivoted in its
extremity the shoe D. In the shoe D is cut a recess a forming at its upper and
lower ends the arms b'. Upon the outer face of the lower arm b' is secured by a
set-screw d the plate E which may be adjusted vertically at will, according to
circumstances. In some cases the plate E will not be required, but, with it the
attachment may be applied to and successfully operated upon almost any sewing
machine. In the shoe D is cut a circular aperture e against which is placed the
swivel consisting of a circular plate having lips h which turn inward and are bent
against the edges of the circular aperture e whereby the swivel is held in place but
at the same time permitted to turn freely against the face of the shoe.
Upon the front portion of the presser-foot A is pivoted the angular eye-bar or
thread-carrier H, one end of which passes through a slot cut in the swivel f while
the other end passes downward and then forward and downward again in proper

page_text: relation to and just above the front end of the foot A where it is provided with an
eye for the embroidering thread.
The rear end of the shoe D is provided with an extension or arm i which projects
downward and has pivoted in its extremity the rear end of the arm J which
extends forward through a slot formed in the presser-foot as shewn terminating in.
proper relation to the front edge thereof. The front end of the arm J is formed
into a head which is enlarged to provent it from passing rearward through the
slot in the presser-foot, and provided with a notch or catch m for the thread. To
the right of the catch m the presser-foot is provided with a similar catch n in
which the sewing needle has the usual vertical movement.
In operation the attachment is applied to the presser-bar in the usual manner
and the head of the screw which fastens the sewing machine needle in the needle-
bar, is placed in the recess a. The embroidering thread is carried from a spool
bobbin or other device and passed through the eye in the bar H thence it is
placed in the notches or catches m n and its extremity passed rearward under the
presser-foot. The fabric being placed on the feed the presser-foot is lowered and
the machine set in motion. The vertical movement of the needle-bar brings the
head of the set-screw securing the needle in place alternately against the upper
and lower arms bb' whereby the shoe D is given an oscillating movement on the
pivot securing it in place. The motion imparted to the shoe D by the needle-
bar is communicated to the angular eye-bar H and the arm J; the bar H having
an oscillatory movement and the arm J a sliding movement in line with the
greatest length of the presser-foot.
The embroidering and sewing threads being in position and the machine set in
motion the embroidering is accomplished, as follows; that is to say. The down-
ward movement of the needle-bar causes the sewing thread and needle to enter the
fabric and depresses the shoe D, which has the effect of throwing the lower arm of
the bar H carrying the embroidering thread, outward to the left, and drawing the
arm J toward the rear; the succeeding upward stroke of the needle-bar causes the
shoe D to ascend whereby the lower arm of the angular bar H is drawn
inward and the arm J forced toward the front. The inward movement of the
lower arm of the angle bar H carries that portion of the embroidering thread in
the eye i to the right in rear of the sewing needle, while the arm J conveys the
portion thereof in the notch m forward beyond the edge of the presser foot A.
The upward movement of the needle-bar continuing, the sewing needle is drawn
upward out of the fabric, when it is immediately returned, now entering on the
opposite side of the embroidering thread to which it was before on account of the
feed motion of the machine, and making a stitch which fastens the embroidering
thread to the fabric. When in this downward movement of the needle-bar
the screw securing the needle in place strikes the lower arm b' the shoe D is
depressed and the embroidering thread carried to the left again by the bar H. Tho
needle-bar being again elevated the operation above described is repeated; at each
upward stroke of the needle-bar the embroidering thread is carried in a diagonal
line in rear of the needle and at each downward stroke the said diagonal line is
stitched down and the said thread again carried to the left, whereby what may be
termed an eye is formed around the stitch securing the embroidering thread and
the said thread is looped or preferably embroidered, in stitches of a cycloidal form.
The motion of the shoe D lost by the device actuating it having to pass through
the recess a before coming in contact with the arms bb gives the sewing needle
time to perform its work as each loop of the embroidery is formed and before
another stitch is made..
:
The swivel f turns slightly with each movement of the bar H thus the said bar
may be rotated upon its pivot without any of its parts being bent or otherwise
deranged.
For the purpose of having the angular arm or thread-carrier H serve as a
take-up if desired an eye jis provided in the outer extremity of the upper portion
through which the embroidering thread is passed, as shown in Figure. 9.

page_text: In Figures 10 to 18 inclusive is illustrated an embroidering attachment which is
effective in its operation but is constructed with a view to cheapness simplicity and
perfection in its details.

sewing machine.

Figure 16 is a side elevation of the hub and its plate.
Figure 17 is a plan of same, and,

In order to attach the embroiderer to the sewing machine I make the foot a and
standard bin one piece and provide a recess c therein for the reception of the
presser bar d of the sewing machine, so that the same may be attached by a clamp
screw at the hole usually provided in such presser-bar for a quilter."
"
By making this foot and standard in one piece instead of being in several pieces
as heretofore, I am able to lessen the cost and avoid the risk of the parts becoming
displaced, and I am also able to shape the recess for the presser-bar to suit
different kinds of sewing machines,-and-in-connection with this standard and foot I
make provision for the introduction of the twisted blade, so that the same may be
inserted or withdrawn as hereinafter set forth, whereas in the embroiderer attach-
ment heretofore made the standard was necessarily in two or more parts so that the
twisted blade could be introduced into its place.
The foot a is hollow and the base plate is applied to the underside of the said
foot to rest upon the fabric that is being embroidered, and at the same time cover
the recess that is formed in the said foot. The screws 2 and 3 inserted from above
the presser foot serve to hold the base plate e to its place at the bottom of the
presser foot.
One of these screws (2) has an eye at the upper end through which
the embroidering cord passes. The base plate e has a tube i rising from its upper
surface and the said base plate and tube are preferably formed of one piece of
metal. The tube i forms a hollow hub around which the tubular gear wheel and
hook revolve and present the embroiderer thread to the sewing thread.
In the machines of this general character heretoforo constructed the tubular
hub has been made separate from the plate and introduced from above into the
revolving hook to hold the same in place and its lower end passed into a hole
through the said plate e the parts being riveted and soldered together, these are
difficult to make and liable to work loose. By my improvement the cost of
manufacture is lessened, and the parts are rendered very strong and durable;
furthermore the plate e is made to cover the recess into which the gear-wheel / at
the bottom of the twisted blade m is placed, so that this gear wheel can be
placed upon a square at the lower end of the twisted blade when the plate e bas
been removed, and the hole in the foot a which receives the cylinder that there is
between the gear wheel and the hook allows such gear-wheel and the pinion n
to be placed in the position relatively to the twisted blade before the base plate is
introduced and secured: this is a great convenience in adjusting the parts when
putting the embroiderer together. The hook o the cylinder and pinion are in one
piece and the pinion is larger than the cylinder so as to be durable, and the
cylinder at the upper part of the pinion is tapering to fit into the hole in the foot a
when the hook is introduced from below into the said foot.
By preference the end of the base plate e is in the form of a half circle to fit
into the recess in which the gear-wheel is introduced: this serves as a guide to
the plate and ensures its proper position.
The twisted blade m is similar to that
part passes through the cylinder journal
similarly shaped hole in the gear wheel.
heretofore in use except that the lower
and the end is squared and enters a
The cylinder journal p has a shoulder

page_text: which rests upon the top of the foot a and supports the twisted blade while it is
being rotated by the vibrating staple or nut q which is moved by and with the
needle-bar r.
In the form in which these embroiderer attachments have been made it has been
necessary to make the standard b in two parts, so that the bracket t can be placed
over the journal at the upper end of twisted blade m.
In order to allow of the foot a the standard. b and the bracket & being made in
one piece I shorten the upper end of the blade so that the journal at the upper
end will pass freely in beneath the bracket t and I then insert a screw 14 down
through the bracket; the said screw having a socket at the lower end for receiving
the journal at the top of the twisted blade.
To secure the embroiderer attachment with facility to the presser-bar I employ a
stud u and tubular nut v the screwed portion of the stud passing through the
standard and the quilter hole in the presser-bar and the stud and nut serving
to clamp the standard firmly to the presser-bar d. The stud u is availed of
for connecting the thread tension and the guide through which the embroiderer
cord passes to the embroiderer attachment.
This thread tension consists of a plate spring w which is folded so as to come
together near the ends; at this place there is a stud 6 and the extreme ends of the
spring plate diverge. This folded plate w is upon an arm 7 that is supported by
the stud u and there is a screw stud 8 where the folded spring w is connected with
the arm 7 and a nut 9 serves to regulate the pressure of the ends of the spring
against each other and in so doing determine the detaining friction that is exerted
upon the embroiderer thread which passes between the springs and over the
stud 6.
It is generally preferable to lead the embroiderer thread through a hole 13 at
the bend of the tension spring thence through between the ends of the spring
to the cyo 10 in the staple or nut q at the base of the needle and throuch
the adjustable eye 11 which is clamped to the arm 7 by the screw 12 thence to the
hole or eye of the screw 2 upon the base of the presser-foot. This arrangement
ensures the proper withdrawal of the embroiderer thread so that it is not in the
path of the descending needle.
The rotating hook carries the thread across the path of the needle as the said
needle rises so that the needle passes down at the other side of the said thread and
sews it to the surface of the fabric thus forming the embroidery.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim
