WEAVING NEEDLE
Arthur S. Nelson, Hartford, Conn.
Application August 1, 1936, serial No. 93,849
(Cl. 139-129)
4 Claims.
'I‘his invention relates to a needle and more
particularly to a Weaving needle having an oifset
pointed end adapted to easily separate’ and suc
cessively pick up adjacent strands of thread or
5 yarn on opposite sides of the needle while weaving.
The general aim of the invention-is to provide
an improved needle by means of which weaving
operations may be performed with greater facility
and speed and with less attention and effort on
the yarn may be located in a well-known manner.
This weaving frame does not comprise a part of
the present invention but is simply illustrated as
a convenient support for the weaving operation,
and it may be constructed in any suitable manner. 5
As herein shown, the yarn is wound about the
successive pins I5 in such a manner as to provide
a multiplicity of slightly spaced but substantially
parallel threads'or strands I 6 extending across
10 the part of the person doing the weaving.
More particularly, I provide an improved nee
dle by means of which the successive threads may
the frame throughout its length and correspond 10
be more conveniently and readily picked up», and
danger of dropping a stitch is minimized.
My improved arrangement permits of the use
15
of a longer needle, the weaving of a wider pattern,
and the weaving with warp threads more tightly
having a suitable strand of yarn Il passing
through its eye I I, is alternately woven above and
beneath the warp strands I6 to form the cross 15
strands or weft. It will be understood, of course,
stretched.
that the strands I6 and Il may comprise indi
vidual strands, or they may comprise a single
`
Other objects and advantages will be evident
as the description proceeds.

My invention accordingly resides in the features
of construction, combination of elements, and ar
rangement of parts which will be exemplified in
the construction hereinafter set forth, and the
scope of the application of which will be indi
cated in the appended claims.
In the accompanying drawing wherein I have
shown, for illustrative purposes, one embodiment
which the present invention may take:
Figure 1 is a sectional view through a weaving
30
frame and showing in side elevation the applica
tion of my needle to a weaving operation for
strands supported on the frame;
Fig. 2 is a fragmentary plan view of a weaving
operation and showing my needle in substantially
the same position illustrated in Fig. 1;
Figs. 3 to '7, inclusive, illustrate the successive
steps of a weaving operation with my needle;
Fig. 8 shows the application of my needle to a
40 weaving operation wherein the warp strands ini
25
tially lie in diiîerent planes; and

To complete the weaving operation, the needle Ill,

Fig. 9 is a fragmentary sectional view taken
substantially along line 9-9 of Fig. 8.
In accordance with my invention, I have pro
’ vided a needle I0 having the usual type `of eye
II adapted to receive a suitable strand of thread
or yarn and having a forward tapering end, gen
erally indicated at I2. This forward end is of a
somewhat stepped shape and adapted to greatly
facilitate a weaving operation in such manner
that it tends to prevent the dropping of stitches.
My needle is shown performing a weaving oper
ation in conjunction with a suitable weaving
frame I4 of substantially rectangular shape and
55 supporting a series of spaced pins I5 about which
continuous strand suitably wound about pins I5,
as illustrated in Figs. 1, 2, 8, and 9. In Figs. 1
and 2, strands I6 are successively wound about
adjacent pins to lie in substantially the same
plane. Figs. 8 and 9 show a different way of
winding the warp strands and wherein the end of
the strands pass around pins I5 in adjacent over
lapping relation to initially position the warp 25
strands in different planes.
Prior types of weaving needles not only tended
to drop stitches, but also had to be carefully and
angularly moved during a weaving operation in
order to elevate or dip the point of the needle
relative to the plane of the warp strands to pick
up successive warp strands. In fact, with a tight
ly stretched warp, this angular movement proved
so diiñcult after the needle had advanced a short
distance across the pattern as to necessitate a
manual manipulation of the warp strands to aid
in locating them above or below the point of the
needle. To overcome these various diñiculties
which are inherent with prior needles, the for
ward tapering end I2 of my needle is provided
with a short offset pointed end portion I2’. This
end portion is substantially parallel to the body
portion of the needle and preferably provided
with a length slightly longer than the diameter 45
of a strand of the material being woven.
The
end portion and body portion of the needle are
interconnected by an intermediate angularly dis
posed short shoulder portion I2” which is of such
length as tgto oifset end portion I2’ to such an
extent that during a weaving operation it will
normally project above or beneath the warp
strands. This shoulder portion prevents tend
ency of the needle to drop stitches and also serves
to cam the warp strands into their required po 55

l
sitions on either side of the needle during a weav
ing operation.
As shown in Figs. 3 to 7 which illustrate the
successive stages of my needle movement during
a weaving operation with respect to three adja
cent warp strands lying substantially in the
same plane and herein designated as a, b, and c,
the needle is ñrst fed beneath strand a and over
strand b with end portion I2’ located above the
10 plane of the body portion of the needle and pro
jecting above the warp strands I6 so that the
shoulder portion I2” first deiiects strand by away
from strand a and towards strand c, as shown
in Fig. 3.
As the needle is further fed forward
15 (Fig. 4), shoulder portion I2” cams strand b
beneath the body portion of the needle and on
the opposite side therefrom from strand a. Un
like p-rior weaving operations, the extent of for
ward needle movement at this time is relatively
unimportant as long as the needle is fed forward
sufñciently to depress strand bt beneath the body
portion of the needle and on the opposite side of
the needle from strand a. It will be appreciated,
of course, that the weaving operation could have
25 been started in a reverse manner to accomplish
the same general result by iirst passing the
needle above strand a, and thereafter beneath
strand b` with the pointed end I'Z' located beneath
the plane of the body portion of the needle.
As herein illustrated, during the initial feed
ing operation of my needle, end I2' and the body
portion of the needle overlie strand b. After the
needle has reached this position7 it is rotated in
either direction through approximately 180° so
that end portion I 2’ depresses against the warp'
strands and lies below the plane of the body por
tion of the needle, as shown in Fig. 5. The
needle is then withdrawn in a reverse direction to
its normal feeding movement and to the posi
tion shown in Fig. 6 wherein shoulder portion I2”
^ deñects strand b towards strand a to such an
extent that end portion I2' will underlie the gen
eral plane of strand c.
The needle is then fed
forwardly again so that shoulder portion I2” will
cam strand c above the body of the needle and
"Y on the oppositeV side thereof from strand b, as
shown in Fig, 7. Similar to the prior forward
feed of the needle, the extent of feeding move
ment at this time need not be precisely limited,
51'). but must be suflicient to engage the body portion
' of the needle beneath strand c. This oscillatory
and rotary feeding cycle is successively repeated
until the needle has passed between all of the
warp strands, after which the needle is pulled
.\ , through the warp to bring the weft strand into
' proper woven relation with the warp strands.
In
View of the deñecting and camming action of
shoulder portion I2", a wider pattern may be
woven than has been found practicable with
60 prior types of needles, since it is not necessary to
angularly move my needle during weaving. Fur
thermore, the deñecting action of shoulder I2”
facilitates weaving between warp strands which
are closer together and more tightly tensioned
than in prior types of weaving operations.
It is not believed necessary to illustrate or
describe in detail the weaving operation with
my needle in respect to warp strands as posi
tioned in Figs. 8 and 9 since the cycle of opera
l tion is identical and the offset of end I2’ is suñi
cient to position the advancing point of my needle
above or beneath the warp strands, as the case
may be, and shoulder I2” operates in the same
manner as previously described.
75,
It will thus be evident that the weaving opera
tion of my needle is easily accomplished by an
alternate forward and reversed feeding operation
interposed by a semi-rotation of the needle, and
the shoulder portion I2” will serve three dis
tinct purposes; namely, separating the strands so
that the pointed end I2' may lie thereabove and
therebeneath, camming the strands into desired
positions, and preventing the tendency of the
needle to drop stitches. It will further be ap
preciated that my needle has provided a con 10
venient and simple means for accomplishing the
weaving operation which does not necessitate a
careful scrutiny of the work by the operator dur
ing a Weaving operation, since the needle may
be fed any distance beyond one of the strands 15
and then turned and pulled back to drop the point
beneath the next strand.
It will also be appreciated that the needle may
be fed through the warp strands by an inter
mittent forward feed interposed by a semi-rota 20
tion of the needle to cam the strands into their
successive required positions. In this method of>
using my needle, it is simultaneously fedforw‘ard
and rotated through approximately 180° to cause
the shoulder portion I2” to flex the strands into
desired positions during its rotation and cam
them back onto the body portion of the needle.>
It will be understood that this combined feeding
and camming action is successively repeated for
each strand, and it will be further understood'that
in either of these methods for employing my
needle, it is preferable to first rotate the needle
2.5.
319
in one direction and then in an opposite direction'
to prevent snarling of the weft strand secured to
the eye of the needle. This latter method of
weaving is particularly useful in weaving the
last few weft strands since the pattern is well
ñlled at this time and the warp strands are less
capable of deñeoting as the needle is moved there
between.
