PROVISIONAL SPECIFICATION.
Improvements in the Harness-cords of Looms for Weaving.
I, GEORGE WRIGHT, of 144, Newcross Street, Bradford in the County of York,
Manager, do hereby declare the nature of this invention to be as follows :—
This invention relates to improvements in the harness cords connecting the mails
through which the warp is passed to the Jacquard mechanism. Such harness cords
have hitherto consisted of yarn or thread generally coated as a preservative with a
coating of linseed oil or the like. This material at the best is far from durable
especially in working in contact with worsted warp, is very inflammable and liable to
be affected by atmospheric changes. Considerable friction is also created between the
several harness cords when in operation and owing to the nature of the preservative
with which they are coated such cords are liable to stick together and by being
operated one with the other cause "stitches" in the fabric being woven. The object
of this invention is to remedy these and certain other defects.
My said improvements consist in employing harness cords of fine copper, iron, steel
or other suitable wire.
To carry out my invention 1 preferably continue the wire from the mail either
double or single up through the "comber board of the jacquard and connect it
directly to the jacquard wires or neck bands and I also pass the wire down beneath the
warp and attach it to the harness weight or "lingo "thus forming the mail and
harness cord of a continuous wire. Or when a separate mail is employed the wire is
preferably continuous from the "lingo" to the jacquard wire.

COMPLETE SPECIFICATION.
Improvements in the Harness-cords of Looms for Weaving.
I, GEORGE WRIGHT, of 144, New Cross Street, Bradford in the County of York,
Manager, do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in the harness cords connecting the mails
through which the warp is passed to the Jacquard mechanism. Such harness cords
have hitherto consisted of yarn or thread generally coated as a preservative with a
coating of linseed oil or the like. This material at the best is far from durable
especially in working in contact with worsted warp, is very inflammable and liable to
be affected by atmospheric changes. Considerable friction is also created between the
several harness cords when in operation and owing to the nature of the preservative
with which they are coated such cords are liable to stick together and by being
operated one with the other cause "stitches" in the fabric being woven.
The object
of this invention is to remedy these and certain other defects.
My said improvements consist in employing harness cords of fine copper, iron, steel
or other suitable wire, arranged as herein described.
To carry out my invention I continue the wire from the mail, or eye through which
the warp is passed, up through the "comber board" and connect it directly to the
Jacquard wires or uprights, or such wire may be attached to "neck bands" either of
ordinary material or of stouter wire. I also continue the wire down from the mail
and attach it directly to the harness weight or "lingoe" and thus form the mail and
harness cord of continuous wire. I preferably form each harness cord of fine

page_text: "
double wire more or less twisted together with the eye for the warp formed in a
similar manner to the eye in an ordinary wire mail. The harness weights or
lingoes may he attached to the bottom of the wire harness cord in the usual
way. Or in order to avoid any liability of loose ends of the wire projecting and
catching neighbouring wires the "lingoes" may be made with vertical slits or holes
at the top and after the ends of the harness cords have been introduced therein
the sides of said slits or holes are pressed, together so as to clamp the ends of the
harness cord between them and thus attach the lingoes thereto.
To fully describe my invention reference is to be had to the accompanying sheet of
drawings forming a part of this Specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1 represents my improved wire harness cords.
Figures 2 and 3 are views on a larger scale at right angles to each other of one
method of attaching the inail to continuous double wire harness cords.
Figures 4 and 5 illustrate a suitable mail for attaching to single wire cords.
Figures 6 and 7 are respectively a plan view and an elevation of a weight or lingoe
on a larger scale illustrating the method of attaching same to the harness cord.
The harness cords A are preferably formed of double wire they are connected in the
manner shown or in any convenient manner to the weights B and either twisted
together to form the eye C for the warp in a similar manner to an ordinary wire mail,
or a separate mail is introduced. The cords are then continued up through the
"comber-board" D and connected to the neck bands E. Or the whole of the wire
harness cords intended to be attached to the same neck band may be twisted together
from the broken line a, upwards and such twisted portions may be connected directly
to the jacquard wires and so dispense with neck bands.
The weights or lingoes may be provided with the ordinary eyes to attach the harness
cords, but I may employ the vertical slit G at the top and press the sides together after
the end of the cord has been inserted.
Instead of forming the eyes C for the warp from the wire of the harness cord
I may introduce separate mails. For this purpose 1 preferably employ the ordinary
metal mail similar to (in Figures 2 and 3, I use fine double wire A for the
harness cord and to attach the mail I thread such wires from opposite sides through
the upper eye e of the mail then pass such wires down opposite sides of the mail
outside the central eye C and through the lower eye i from the same side that
they are passed through the top eye. In this manner the wire does not interfere with
the central eye for the warp and each end of the mail is confined between the double
wire and is so prevented from catching neighbouring wires, mails, harness or warp
threads.
By employing mails tapering to a point at each end as shown by (2 Figures 4
and 5 single wire harness cords A may be used and such mails neatly soldered in
position thereon so that the ends of the mails taper down to the size of the wire A
without leaving an abrupt shoulder liable to catch.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare what I
claim is:
In weaving looms, the combination with Jacquard mechanism of wire harness cords,
substantially as herein shown and described.
