8 Claims. (Cl. 139—89)
In
This invention relates to Jacquard loom har
ness, and it relates more particularly to improved
means for attaching a lingo to the lower end of a
necting devices detached, in the form assumed
before the same is mounted onthe lower end of
the heddle for the purpose of attaching the lingo
jacquard heddle.
thereto; and
Heretofore various means have been devised or
suggested for attaching lingoes to the lower ends
of the heddles in Jacquard loom harness. None
of these have been entirely satisfactory, princi
pally by reason of the wear which occurs at the
eye of the lingo on account of the lingo swinging
with respect to the lower end of the heddle dur
ing the operation of the loom, and also by reason
of the fouling of the harness at the point of con
nection of the lingo to the heddle which frequently
occurs and which causes imperfections in the
woven pattern.
The principal object of the present invention
' is to provide a simple, ef?cient, yet inexpensive,
means for attaching a lingo to the lower end
20 of the heddle.
'
A further object of the invention is to provide
a device by means of which lingoes with worn
eyes may be readily and expeditiously replaced.
A further object of the invention is to provide
25 improved means for attaching lingoes to heddles
in such manner that wear will be reduced to a
minimum.
With the foregoing objects in view, this in
vention contemplates the provision of a novel
30 form of lingo attaching member and a suitable
formation of the lower end of the heddle, whereby
said attaching member may be quickly and con
veniently mounted on the heddle and which when
so mounted will be ?xedly and rigidly attached
35 thereto.
The nature end characteristic features of the
invention will be more readily understood from
the following description, taken in connection
with the accompanying drawing forming part
40 hereof, in which:
Figure 1 is a front elevation of a Jacquard
loom heddle having a lingo attached thereto by
means embodying the main features of the pres
ent invention;
Fig. 2 is a side elevation thereof;

Fig. 3 is an enlarged fragmentary detail view
illustrating the structure at the point of con
nection of the upper end of the lingo to the lower
end of the heddle;
Fig. 4 is a perspective view of the portion of the
structure illustrated in Fig. 3;
Fig. 5 is a perspective View of the lower end of
the heddle, suitably perforated for the reception
of the connecting device;

Fig. 6 is a perspective view of one of the con
Fig. '7 is. a perspective view of the upper end
of a lingo of an ordinary type adapted to be at
tached to the lower end of the heddle.
It should of course be understood that the
drawing and description herein are illustrative
merely and that various changes and modi?ca 10
tions may be made in the structure disclosed with
out departing‘from the spirit of the invention.
Referring to the drawing, in the particular em
bodiment of the invention therein shown, in is a
jacquard heddle preferably made of a strip of 15
thin flat metal. This strip is provided at its up
per end with an eye H for the attachment of the
usual control cord (not shown) of the jacquard
mechanism. The heddle is also provided with
the usual warp eye l2 intermediate the ends
thereof.
The lower end of the heddle is provided with
a plurality of openings I3, I4 and I5 punched
therein. The opening l3 nearest the lower end
of the strip is preferably somewhat longer than 25
the openings 14 and I5 for a purpose to be pres
ently explained.
‘
The lingo may be of the ordinary form com
prising a rod i6 having its upper end ?attened
as at IT, and provided in said ?attened portion
with an eye l8 for the attachment of the lingo
to the heddle.
The device for attaching the lingo to the hed
dle comprises a peculiarly shaped clip 20’ shown
in detached perspective in Fig. 6, and preferably
made from a thin, narrow strip of metal; the strip
being substantially equal in width to the width
of the openings l3, I4 and [5 in the lower end of
the heddle. The strip is bent and formed to pro
vide an eye portion 2| approximately circular in 4.0
conformation from which two legs 22 and 23
extend upwardly.
‘ ‘
One of these legs, 22, which is substantially
shorter than the other, extends, in the operative
condition of the device, upwardly as at 24 along
one face of the lower end of the heddle, and
thence passes through the opening l3 nearest
the lower end of the heddle, thence extending as
at 25 along the other face of the heddle to the
next opening 14 through which it passes, having its end 26 bent over upon the face of the heddle
along which it ?rst extends.
The other leg 23 of the clip 20 extends up
wardly from the eye portion 2|, along the oppo
site face of the lower end of the heddle as at 21 55

until it reaches the point where the portion 25
of the leg 22 is disposed on that face of the lower
end of the heddle.
At this point, the leg 23 is
offset as at 28 so as to ‘clear the portion 25 of
the leg 22. The upper end of the leg 23 bears
as at 29 against the face of the lower end of the
heddle, and thence extends through the opening
I5 therein, having an end portion 30 bent down
3. In Jacquard loom harness, the means for
attaching a lingo to a heddle comprising the pro—
vision of a plurality of openings in the lower
end of the heddle, and a clip made of a narrow
strip of metal bent to provide an eye portion for
engaging the eye portion of the lingo, said clip
having legs extending upwardly from the eye por
tion, one on each face of the heddle, and each
wardly on the other face thereof (see Fig. 3).
The clip 20 is initially formed in the condition
of said legs having portions extending through
shown in Fig. 6 of the drawing, having the leg
portions 22 and 23 ?aring with respect to each
by to position the clip ?xedly with respect to the
other. When it is desired to use the same for
connecting a. lingo to the lower end of the hed

attaching a lingo to a heddle comprising the pro
vision of a plurality of openings in the lower end
of the heddle, and a clip made of a narrow strip
of metal bent to provide an eye portion for en
dle, the eye portion of the lingo is ?rst passed
over one of the legs of the fastening device until
it is positioned within the eye portion I1 there
of. The shorter leg 22 of the clip 20 is then in
serted through the elongated opening [3 of the
at least one of said openings in the heddle there
heddle.
Y
gaging the eye portion of the lingo, said clip
having legs extending upwardly from the eye por
lower end of the heddle, then turned over to per
tion, one on each face of the heddle, one of said
mit the end portion 26 thereof to be passed
legs having a portion extending through one of
the openings in the heddle and having its end
extending through another of the openings, and
then bent over, and the other of said legs having
its end extending through one of said openings
through the opening It, simultaneously passing
the bent over end portion 30 at the upper end of
the longer leg 23 through the aperture IS in the
lower portion of the heddle. The end portions
26 and 30 of the legs of the clip 20 are then bent
down to the positions shown in Figs. 1 to 4 of the
drawing.
It will be noted that in the foregoing arrange
30 ment, the fastening device is so mounted that
there will be no movement thereof with respect
to the lower end of the heddle, and further that
by reason of the foregoing, there will be little
likelihood of the heddles and lingoes fouling on
each other when the shedding takes place.
By reason of the rigid connection of the at
taching device to the lower end of the heddle,
wear on the eye of the lingo will be considerably
reduced, yet, on the other hand, in the event of
40 excessive wear on the eye portion of the lingo,
or even excessive wear on the eye portion of the
attaching device, renewal of these parts may be
readily effected by merely bending up the bent
over end portions 26 and 30 of the legs of the
,, attaching device, whereupon the attaching de
' vice may be readily removed from the lower end
of‘ the heddle to permit unworn parts to be sub
stituted.
