This invention‘ relates to attachments for sew
ing ‘machines andhas particular reference to an
embroiderer or device for simulating hand em-.
broidered fancy work.
The principal object of the invention is to pro
vide an attachment, adaptable to conventional
types of sewing machines, designed to stitch em~
broidery thread, or yarn, onto fabric in any de
Another object of the invention is in the pro
vision of an attachment of this character capable
of keeping the embroidery thread or yarn taut
in order that the stitching operation is properly
completed and in preventing the stitching needle
from sewing to the sides of the yarn or thread to
be stitched, as well as in preventing the ap~
pliqued material from buckling or becoming over
A further object of the invention is in the pro
vision of an embroidering attachment capable
of twisting yarn, or similar material to be sewed,
to fabric in a manner that the ?nished result of
simulated embroidery is neat and closely sewed.
Broadly the invention seeks to provide an em~
broidery attachment for sewing machines capable
of properly preparing yarn, or the like, for a
stitching operation.
With the foregoing objects as paramount, other
and lesser objects will become manifest as the
description proceeds, taken in connection with
the accompanying drawing, wherein:
Figure 1 is a perspective View of the invention
attached to the head of a sewing machine.
Figure 2 is an elevational view particularly
illustrating the spring tension guide, the move
ment of which is shown in dotted lines.
Figure 3 is another elevational view of the in
vention, illustrating the adjustments of the disc
supporting bracket and the tension spring guide.
Figure 4 is a perspective view of the spring
tension guide detached from the device.
Figure 5 is a plan view of the presser-foot and
its accompanying parts.
Figure 6 is a fragmentary view of a piece of
fabric having a design of yarn or embroidery
thread stitched thereon.
Figure 7 is a View taken transversely through
the needle bar and spring tension guide, and
Figure 8 is a fragmentary detail View of the
yielding free end of the guide.
Continuing with a more detailed description
of the drawing, l designates a sewing machine
‘ head having a presser-foot bar 2 to which the
invention is attached in place of the conventional
5 presser-foot. For attachment, the invention is
provided with a recessed shank member 3 having
a bayonet slot 4 as shown in Figure 2, which re
ceivesv the conventional presser-foot set screw 5,
thus rendering the device vertically adjustable on
the presser-foct bar 2.‘ At the lower end of the
shank 3, an integral crescent shaped presser-foot
6 is provided having positioned across its upper
side a V-shaped retainer 1 as illustrated in Fig
ure 5.
On one side of the shank 3, and to the side of
the slot 4, there is pivotally attached at a a ten
sion spring guide 8, oblong in shape, and is re
tained in place by contact with the needle clamp 9
of the reciprocating needle bar [0. Integral with
the lower end of the tension spring there is a 15
V-shaped and angularly disposed guide ll, the
lower point of which, together with the angle of
the retainer 1 forms an aperture through which
the needle l2 operates. A yarn or thread re
tainer I3 is provided near the upper end of the
guide‘ H and extends partially across the guide
opening illustrated in Figure 3 or 4.
On the upper surface of the presser-foot ii and
pivoted at the point b there is connected a
bracket Ill and at the upper end of the bracket
Hi there is journaled for free rotation, a disc IS,
the mounting being constructed with an opening
it therethrough.
A hook I‘! is positioned on the surface of the
disc l5 toward the presser-foot 6, its point being 30
directed toward the disc periphery.
In operation, embroidery thread or yarn I8 is
threaded through the opening 16, brought over
the disc hook l1, thence downwardly through the
guide H and its retainer l3 and through the ap
erture formed by the guide II and the angle of
the retainer 7 which is mounted on the presser
foot 6, thus presenting the yarn or thread in posi
tion to be stitched to the fabric by the needle 12.
In order that the yarn [8 may be twisted for 40
the sewing operation, the disc I5 is manually
rotated in the desired direction, the yarn being
kept taut by holding the same at the outer side
of the opening l6.
, Since the tension spring contacts the needle
clamp 9 in the manner previously described, the
guide is moved in a reciprocating motion, as 11
lustrated in dotted lines in Figure 2, thus feeding
the thread downwardly during the sewing oper
When the presser-foot 6 is adjusted in its up
per position by loosening the screw_5 and raising
the shank 3, the fabric is allowed to move from
side to side or in any direction, since the mate
rial is then not acted upon by the feed dogs 55
(not shown).
Consequently any desired design
can be effected.
Manifestly the structure shown and described
is capable of changes and modi?cations by those
skilled in the art, and such changes which may
be resorted to from time to time which may be
considered within the intent of the invention
may also be considered as falling within the
scope and meaning of the appended claims.
What is claimed is:
1. An embroidering attachment for a sewing
machine comprising in combination with the
the lower end of the said presser-foot bar, a re
tainer positioned across the said presser-foot,
and angular recess in the said retainer, resilient
means attached to the upper portion of the said
presser-foot to be frictionally engaged by said
needle bar to be displaced thereby as the needle
bar descends, guide means positioned at the lower
end of the said resilient means, and means for
twisting and preparing the said thread or yarn
for the sewing operation.
3. In an attachment for a sewing machine, a
vertically adjustable presser-foot for attachment
needle bar of said machine, a presser-foot for at
to the lower end of the presser-foot bar of the
tachment to the presser-foot bar of the said sew
said machine, a V-shaped retainer laterally po
sitioned across the said presser-foot, an angular
ing machine, a V-shaped retainer positioned
across the said presser-ioot, reciprocating guide
means actuated by the needle bar of the said
machine, and means mounted on the said presser
foot for twisting and preparing the thread to
be sewed for the stitching operation.
2. An attachment for sewing machines for em
broidering thread or yarn to fabric, comprising
in combination with the presser-foot bar and
the needle bar of the said sewing machine, a
crescent shaped presser-foot for attachment to
bracket pivotally mounted on the said presserr
foot, a freely rotating disc mounted near the
upper end of the said bracket having a central
opening through which yarn is passed, means on
said disc for loosely holding said yarn, and means
positioned between the said presser-foot bar and
the needle bar of the said machine for recipro
cally feeding the said yarn into position for
