Seam for Door P
I, CHARLES EDWIN BENTLEY of 204 Greene Street, New York, County and
State of New York, United States of America, Manufacturer, do hereby
declare the nature of my invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:―
11-
My invention relates to a novel seam for sewed fabrics, and has for its object to
provide an ornamental seam of this general character formed with a foundation
fabric and threads held thereto and so interlocked with each other that the seam
will not unravel and cannot be easily ripped out by pulling the threads.
In the accompanying drawing similar numerals indicate like parts in all the
views.
Figure 1 shows my seam as it appears at the upper face of the fabric.
Figure 2 shows the seam at the lower face of the fabric.
Figure 3 is a transverse section on the line x, x, in Fig. 1.
Figure 4 is a longitudinal section along the purled edge of the seam, and taken
on the line y, y, in Fig. 1.
Figure 5 is a perspective view illustrating use of the invention for overseaming,
as when making button holes, etc.; and
Figures 6 and 7, show two of many different forms of scalloped embroidery seams
which may be produced.
My improved seam comprises three threads 1, 2, 3, worked on and through a
foundation fabric 4. The upper thread 1, is carried by a needle, the lower thread 2, is
a shuttle thread, and the thread 3, is the main ornamental thread of the seam and is
carried by a second needle. The thread 3, is looped through the foundation fabric
at one edge of the seam, and is also looped transversely upon both upper and lower
faces of the fabric to the second or opposite edge of the seam by looper devices
which may have any suitable construction and need not be described. At the
second or opposite edge of the seam the threads 1, 2, are interlocked with each
other after passing respectively through the upper and lower loops of the main
thread.
We will suppose the thread 3, is looped by its needle through the fabric 4, at 5.
The looper devices now catch this thread and loop it transversely or sidewise upon
The
both upper and lower faces of the fabric 4, to the opposite edge of the seam.
needle carrying the upper thread 1, now loops this thread either through the
foundation fabric or past an edge thereof, and within the bends or turns 6, 6, of
the two lateral upper and lower loops of the thread 3, at the second edge of the
seam. The shuttle thread 2, is now carried through the loop of thread 1, below
the fabric 4, and when the needle carrying the thread 1, next rises and the
threads 1, 2, have proper tension, these two threads will be securely interlocked
with each other through the loops of the main ornamenting thread 3.
Successive stitches made in this manner, produce a seam which has a purled edge
along the threads 1, 2, next the bends 6, of the loops of the main thread 3, at both
upper and lower faces of the fabric 4, and the finished seam has substantially the
same ornamental appearance at opposite faces of the foundation fabric, all as
clearly shown in the drawing.
The second purled edge of the seam may be worked at any desired distance from
the edge of the foundation fabric 4, as shown in Figures 1 to 4, of the drawing, or

page_text: said purled edge of the seam may be worked outside the edge of the fabric as a
binding therefor, in the manner known as overseaming, as when making button
holes, etc., and as illustrated in Figure 5, of the drawing.
By making the thread carrying needle or needles adjustable to vary the length
of the transverse loops of the thread 3, embroidery scallops of various designs may
be worked on the foundation fabric; examples being shown in Figures 6 and 7, of
the drawing.
My improved seam differs from other seams of like general character by having
the two threads 1, 2, passed through the upper and lower loops of the main thread 3,
and interlocked with each other like the needle and shuttle threads of an ordinary
lock-stitch sewing machine, whereby the transverse loops of the thread 3, are
securely held by the locked stitches of the threads 1, 2, thus preventing the seam
from being ripped out or unravelled by pulling the threads.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
The improved seam for sewed fabrics, comprising one or more thicknesses of
fabric and three threads 1, 2, 3, combined therewith; the thread 3, being passed
in loops through the fabric at one edge of the seam during successive stitches and
looped transversely from said points of passage on both upper and lower faces of
the fabric to the opposite edge of the seam, a loop of thread i, being passed through
each loop of thread 3, on the upper face of the fabric, and the thread 2, being
passed through the corresponding loop of thread 3, on the lower face of the fabric
and then through the loop of thread 1, and around one strand of said loop and thence
out through the loop of thread 3, on the lower face of the fabric, whereby
threads 1, and 2, are interlocked through the loops of thread 3, substantially as
described.
