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.
In a Jacquard harness constructed according to our invention we use, (in place
of the ordinary mail) a piece of wire preferably steel of any convenient length with.
an eye or opening at each end to receive the thread, wire or equivalent which
connects the piece of wire to the Jacquard machine at one end and to the lingoe.
at the other end, and a special eye or opening preferably in the centre to receive.
the warp thread.
"
The special eye for the warp thread is what is termed a needle eye and it is.
formed. by slitting or punching the metal and then stretching the hole thus made
which is subsequently smoothed and finished. The eyes at the ends of the mail!
may either be needle eyes or if preferred the wire coupling may be slightly
flattened at each end and a small hole punched therein.
In all cases we prefer to construct this wire 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 the joints of connection between this wire and the thread, wire or
equivalent which connects it to the other portions 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.

page_text: In a Jacquard harness constructed according to our invention we use (in place
of the ordinary mail) a piece of wire preferably steel of any convenient length with
an eye or opening at each end to receive the thread, wire or equivalent which
connects the piece of wire to the Jacquard machine at one end and to the lingoe at
the other end, and a 'special eye or opening preferably in the centre to receive the
warp thread.
And in order that our invention may be fully understood and readily carried
into effect we will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figures 1 and 2 represent a combined mail and couplings made according to our
invention.
In these views,-a designates the piece of wire which constitutes the combined
mail and portions of the upper and lower couplings and in which at about mid-
length is formed the special eye or opening a' for the warp thread, and at the ends
are formed the eyes a² a³ to receive the thread or other connections from the
Jacquard machine and lingoe.
This special eye a' for the warp thread is what is termed a needle eye and it is
formed by slitting or punching the metal and stretching the hole thus made, which
'is' subsequently smoothed and finished. The eyes a a' at the ends of the mail
may either be needle eyes or if preferred the wire coupling may be slightly flattened
at each end and a small hole punched therein. The eye a² receives the thread,
wire or equivalent which connects the part a to the Jacquard machine, and the
eye a³ receives the thread or equivalent c by which it is connected to the lingoe d.
In all cases we prefer to construct the mail or part a of such length that the
lower portion from the eye a¹ to the eye a³ is more than the depth of a shed below
the yarn whilst the upper portion from the eye a¹ to the eye a³ is more than a shed
"higher than the yarn, in order to prevent the warp threads or yarn from coming in
contact with the joints of connection between the part a and the thread, wire or
equivalent which connects it to the other portions of the harness.
:
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
1. we claim is :-.
The part a which constitutes a combined mail and portions of the upper and lower
couplings and consists of a single piece of wire having a special needle eye for the
warp thread, and also an eye or opening at each end for the connections by which
it is coupled to the Jacquard machine and lingoe respectively substantially as
herein set forth.
