AN IMPROVED METHOD OF ATTACHING HARNESS TO THE HOOKED WIRES AND SHAFTS IN JACQUARD MACHINERY
Year: 1884

page_text: I, THOMAS SUTCLIFFE of 18 Bold Street Accrington in the County of Lancaster
Iron moulder do hereby declare the nature of my invention for "AN IMPROVED
METHOD OF ATTACHING HARNESS TO THE HOOKED WIRES AND SHAFTS IN JACQUARD
MACHINERY," which invention has been communicated to me from abroad by
Holden Rigby and Lindsay of Paterson New Jersey, United States of
America, to be as follows:-
My Invention has reference to compound Jacquard mechanism employed in
weaving damasks, and other ornamental fabrics.
The harness in these compound jacquards is split or divided into two sets or
leases, the whole of which are attached by a neck cord to a hooked wire from
which it is suspended.
In addition to this cach divided set of harness or leases are supported by a
heald shaft which is raised by an independent set of hooks, as is well understood
in this description of machinery.
The method of connecting or attaching the neck cords to the shafts have always
been clumsy and defective, besides allowing of great wear and tear of the parts,
necessitating frequent stoppages of the Loom for repairs.
The object of my Invention is to arrange the parts so that the harness can be
attached to the hooks and shafts in a more simple and effective manner, and at the
same time be more durable.
For the purpose of carrying out the first part of my Invention I have the shafts
perforated with any suitable number of holes through which the harness is passed,
consequently when the shafts are raised for opening the warp threads, there is no
loup or slack harness around the outside of the shafts as is the case at present, so
that wear and tear by chafing or friction is avoided.
Secondly. Each lease of harness above the shafts is provided with a cushion of
india rubber or other suitable material so that when the shafts are raised they come
into contact with the india rubber cushion and prevent any sudden jar or strain
upon the harness, or neck cords, there is also less strain upon the warp which the
harness opens and closes.

page_text: I, THOMAS SUTCLIFFE, of 18, Bold Street, Accrington, Lancashire, Iron Moulder,
do hereby declare the nature of my invention for " AN IMPROVED METHOD OF
ATTACHING HARNESS TO THE HOOKED WIRES AND SHAFTS IN JACQUARD MACHINERY
A communication to him from abroad by Holden Rigby and David Lindsay, of
Paterson, New Jersey, United States, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention has reference to compound Jacquard mechanism employed in
weaving damasks, and other ornamental fabrics. The harness in these compound
Jacquards, is split or divided into two sets or leases, the whole of which is attached
by a neck-cord to a hooked wire from which it is suspended.
In addition to this, each divided set of harness or leases are supported by a heald
shaft, which is raised by a independent set of hooks, as is well understood in this
description of machinery.
The method of connecting or attaching the neck-cords to the shafts has always
been clumsy and defective, besides allowing of great wear and tear of the parts,
necessitating frequent stoppages of the loom for repairs.
The object of my invention is to arrange-the-parts-so-that-the-harness-can-be-
attached to the hooks and shafts in a more simple and effective manner, and at the
same time be more durable.
For the purpose of carrying out the first part of my invention I have the shafts
perforated with any suitable number of holes, through which the harness is passed,
consequently when the shafts are raised for opening the warp thread, there is no
loop or slack harness around the outside of the shafts as is the case at present, so
that wear and tear by chafing or friction is avoided.
Secondly. Each lease of harness above the shafts is provided with a cushion of
india rubber, or other suitable elastic material, so 'that when the shafts are raised
they come into contact with the india rubber cushion, and prevent any sudden jar
or strain upon the barness or neck-cords; there is also less strain upon the warp
which the harness opens and closes.
In order that this invention may be better understood reference is made to the
accompanying sheet of drawings, wherein Fig 1, is an enlarged view of the system
I adopt for connecting the harness A to the lifting hooks B and shafts C. It will
be observed that the neck-cords D are made with a loop at their upper ends, and
are slipped onto the lifting hooks B. These neck-cords D are attached by knots to
the harness A, but at a given point a in the said cord a knot is formed, under
which knot is a washer b made, of india rubber or other yielding material for
forming a cushion. The shafts C have any suitable number of holes bored in them,
through which are passed the cords D, the washer b resting on the top of the said
shafts. The harness is provided with "mails" c and "lingoes "d as usual. In
order to shew the difference and advantages of my improved system over the
system at present in use, I have shewn in Fig 2 part of a Jacquard frame E having
4 hooks and 8 shafts on my system, and 4 hooks and 8 shafts on the old system.
As will be understood by those conversant with the trade, that sometimes the
hooks B are lifted for raising harness A or leases e and f, and that at other times
one or other of the shafts C are raised according as they are selected by the
pegging apparatus. For the purpose of illustrating my invention and shewing its
advantages, I have shewn in Fig 2, two hooks raised up, H on the old system, and
H¹ on the new system, now on reference to H it will be seen that the neck-cords D

page_text: are looped and hanging loose between the shafts, whilst on reference to H' it will
be seen that the neck-cords have come up through the holes made in the shafts C,
and that there is no loop nor slack, but all is perfectly straight.
Another illustration is shewn in Figs 3 and 4, where the former is the old system
and the latter the new. In these cases the hooks B have not been lifted, but one
of the shafts have, and the difference will be observed, for whilst in Fig 4 a loop g
is formed, it is above the shafts and out of reach of being chafed, but in Fig 3 a
loop his formed below or between the shafts, and as they are much nearer together
than shewn on the drawing, and constantly passing each other, there is much wear
and tear of the loop, necessitating frequent stoppage of the loom for repairs, and
consequently loss of time. Fig 5 is front view of the shafts, shewing one up and
the other down, Figs 6 and 7 are detached views of the neck-cords tied to the
harness, the loops I in Fig 6 shew the place where the shafts are inserted.
The primary object of the cushions bis to prevent sudden jirking when the
shafts are either raised or lowered, and to preserve the knots a, and in general to
soften the action of the parts when moving up or down.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
Firstly. The use and employment of the shafts C, provided with holes for the
cords to pas through in manner substantially as herein described.
Secondly. The use and employment of the washers or cushions b for purposes
set forth.
