PROVISIONAL SPECIFICATION.
Improvements in the Jacquard Harness of Looms for Weaving.
We, THOMAS TAYLOR, of the firm of Barlow and Jones Limited, of Bolton,
in the County of Lancaster, Manufacturers, and HENRY FLETCHER, of 30 Hibbert
Street, Bolton aforesaid, Weaver, do hereby declare the nature of this invention to
be as follows
Our invention relates to improvements in the Jacquard harness of looms for
weaving and the object of our invention is to increase the durability of that part
of the harness which comes in contact with the warp in the loom; this portion of
the harness called the coupling is usually made in three parts the upper and lower
parts being linen thread joined together by the third part which is a metal or other
mail and this coupling is soon worn and broken at the joints of connection between
the metal or other mail and linen thread, in consequence of the friction of the
yarn in the loom, or of one coupling with another.
Our improvements consist essentially in forming the mail (or eye for the warp)
and the upper and lower parts of the coupling and the lingoc all of one piece of
metal or in two or more separate pieces soldered or otherwise suitably secured
together so as to form one piece when thus united. In the upper portion of this
combined mail, coupling and lingoe we form an eye or opening to receive the
thread, wire or equivalent which connects to the Jacquard machine, and the lower
portion is weighted, as the equivalent for the ordinary separate lingoe, either by
increasing the length in one uniform thickness or by increasing the section of the
metal or by soldering or otherwise suitably securing additional metal thereto.
In all cases we prefer to construct the combined mail and coupling of such length
that the lower portion is more than the depth of a shed below the yarn whilst the
upper portion is more than a shed higher than the yarn in order to prevent the yarn
from coming in contact with any other portion of the harness.

Improvements in the Jacquard Harness of Looms for Weaving.
We, THOMAS TAYLOR, of the firm of Barlow and Jones Limited, of Bolton,
in the County of Lancaster, Manufacturers, and HENRY FLETCHER, of 30 Hibbert
Street, Bolton aforesaid, Weaver, 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 :-
Our invention relates to improvements in the Jacquard harness of looms for
weaving and the object of our invention is to increase the durability of that part
of the harness which comes in contact with the warp in the loom; this portion of
the harness called the coupling is usually made in three parts the upper and lower
parts being linen thread joined together by the third part which is a metal or other
mail and this coupling is soon worn and broken at the joints of connection between
the metal or other mail and linen thread, in consequence of the friction of the yarn
in the loom, or of one coupling with another.
Our improvements consist essentially in forming the mail (or eye for the warp)-
and the upper and lower parts of the coupling and the lingoe all of one piece of
metal or in two or more separate pieces soldered or otherwise suitably secured.
together so as to form one piece when thus united.

page_text: In the upper portion of this combined mail, coupling and lingoe we form an eye-
or opening to receive the thread, wire or equivalent which connects to the Jacquard
machine, and the lower portion is weighted, as the equivalent for the ordinary
separate lingoe, either by increasing the length in one uniform thickness or by
increasing the section of the metal or by soldering or otherwise suitably securing
additional metal thereto.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings in which―
Figs. 1 and 2 represent two views of a combined Jacquard mail couplings and
lingoe made according to our invention.
The combined mail or eye for the warp, and upper and lower part of the
couplings are formed of a single piece of by preference steel wire which is provided
with an eye 1 near its centre for the warp thread, and at its upper end it has an
eye or opening 2 of any suitable shape and size to receive the thread 3 or it might
be a wire for coupling the mail to the Jacquard machine; the mail is weighted, as
the equivalent for the ordinary separate lingoe, either by increasing the section of
metal or by soldering, brazing, or otherwise suitably securing additional metal 4 to.
the lower part of the wire.
The warp eye 1 is preferably formed by slitting the metal, then stretching and
opening the eye previous to rounding and smoothing the same after which the
metal may be hardened to increase the durability of the warp eye.
In all cases we prefer to construct the combined mail and coupling of such length
that the lower portion is more than the depth of a shed below the yarn whilst the
upper portion is more than a shed higher than the yarn in order to prevent the yarn
from coming in contact with any other portion of the harness.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A Jacquard mail with warp eye, couplings and lingoe formed out of one piece
of metal or of two or more pieces of metal secured together so as to form a single
piece substantially as herein described and illustrated.
