I, JOHN KING MACDONALD, Manager of The Singer Manufacturing Company,
Kilbowie, Dumbartonshire, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement: -
This invention has for its object to provide a cording attachment for use with
multiple seam sewing machines, and by the use of which a plurality of cords,
each centrally enfolded within a separate strip of material, may be guided to
the needles of the machine in such a manner that the opposite edges of each
strip may be turned under, and each strip and cord be stitched down to a piece
of under-lying material by two rows of stitches. The improved corder is intended
more particularly for use in corset and other work in which the under-lying or
base material is to be provided with a series of corded overlays.
To this end the improved attachment comprises a plurality of rearwardly
tapering folding strip-guides, preferably made in the form of slightly curved
flattened tubes each of which is provided with a centrally arranged cord-guide
or tube, said guides being sustained in operative position in front of the needles
by a suitable support which will preferably be the presser-foot of the machine
and which presser-foot will be properly recessed in its bottom for the easy passage
beneath it of the cords and folded strips.
In the accompanying drawings Figs. 1 and 2 are top and bottom views,
respectively, of one form of the improved corder, and Figs. 3 and 4 are front
and rear views, respectively, of the same. Fig. 5 is a section on line 5-5, Fig. 1,
and Fig. 6 a side view of the improved corder. Figs. 7 and 8 are top and front
views, respectively, of a three-strip and three-cord corder, and Fig. 9 is an
enlarged view illustrative of the work done with the improved corder.
A denotes a guide support preferably made in the form of a wide presser-foot
provided with a shank a for attachment to a presser-bar of a sewing machine,
and with a series of needle-holes or slots a¹. To the front or toe portion of the
presser-foot A are attached a plurality or series of inclined rearwardly tapering
strip-folding guides 6 preferably in the form of flattened tubes slightly curved
transversely and each provided beneath with a centrally arranged cord-guide c,
said cord-guides being preferably soldered or otherwise suitably attached to the
said strip-guides. The presser-foot is provided on its underside with cord

page_text: grooves a², arranged in line with the cord-guides c, and with strip grooves as
arranged in line with the forward or delivery ends of the strip-folding guides b.
the needle-holes a¹ intersecting these strip grooves a³ and straddling the cord
grooves ; while the ribs at between the strip grooves enable the presser-foot
to bear properly on the work between the outer parts or end bearing surfaces a
of said foot. The cord-grooves a² are centrally located in the strip-grooves a³
and are somewhat deeper than said strip grooves.
In order to do close cording in which each cord is overlaid by a separate
strip of material, with under-folded edges secured by two rows of stitches, it
is necessary to stagger" the strip-guides or arrange them in different hori-
zontal and vertical planes, so that the guides of one row alternate with or are
The rearwardly
partly between (in a vertical plane) the guides of the other row.
tapering strip-folding guides are of well-known construction, and serve to fold
under the opposite edges of the strips e passed through them, these folded-in
edges being sewed down to the backing-piece of material f on each side of the
cords g by two rows of stitches h.
It will be understood that any desired plural number of the strip-folding
guides b and cord-guides e may be employed, according to the number of needles
of the machine with which the attachment is to be used. Thus the form of
attachment shown by Figs. 1, 2, 3, 4 and 5, and having six each of these guides,
is intended for use with a twelve-needle sewing machine, while the form of the
invention shown by Figs. 7 and 8, and having three each of these guides, is
intended for use in a six-needle machine.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is: -
1. A sewing machine cording attachment comprising the combination with a
suitable support, of a plurality of rearwardly tapering strip-folding guides, each
of which is provided with a centrally arranged cord-guide, said strip-folding
guides being "staggered" or arranged in different vertical and horizontal planes,
so that those in one horizontal plane will come between or will alternate vertically
with those in another horizontal plane.
2. A sewing machine presser-foot provided with a series of needle-holes and
having attached to its front or toe portion a plurality of inclined, rearwardly
tapering, strip-folding guides, each of which is provided with a centrally arranged
cord-guide, said presser-foot having in its bottom a series of cord-grooves arranged
in line with said cord-guides.
3. A sewing machine presser-foot provided with a series of needle-holes and
having attached to its front or toe portion a plurality of inclined rearwardly
tapering strip folding guides, each of which is provided with a centrally arranged
cord-guide, said strip-folding guides being "staggered" or arranged in different
vertical and horizontal planes, so that those in one horizontal plane will come
between or will alternate vertically with those in another horizontal plane.
4. A sewing machine presser-foot A. the bottom of which is provided with a
series of cord-grooves aª and with a series of strip-grooves a³ in which said cord-
grooves are centrally located, said foot having also a series of needle-holes inter-
secting said strip-grooves, and the front or toe portion of said foot being provided
with a plurality of inclined, rearwardly tapering strip-folding guides beach of
of which is furnished with a centrallv-placed cord-guide c.
5. A sewing machine presser-foot A the bottom of which is provided with a
series of cord-grooves a³ and with a series of strip-grooves a³ in which said cord-
grooves are centrally located, said foot having also a series of needle-holes inter-
secting said strip-grooves, and the front or toe-portion of said foot being provided
with a plurality of inclined, rearwardly tapering strip-folding guides beach
of which is furnished with a centrally-placed cord-guide c, said strip-folding guides

page_text: being staggered or arranged in two different horizontal planes or rows with the
strip-guides of one row alternated with or placed partly between the strip guides
of the other row.
