We, JOHN JARDINE of Raleigh Street and CORNELIUS HENRY CRAWLEY of
Thrumpton Terrace, Briar Street, both in the town and County of the town of
Nottingham, Machinists, do hereby declare the nature of this invention to be as
follows
-
Our invention has for its object improvements in jacquard needles or cross wires
used in jacquards applied to machines for making lace curtains and in other similar
jacquards and also in the method of supporting and guiding the said needles or cross
wires.
Jacquard needles or cross wires as hitherto constructed have all been formed with
eyes or long slots through them; in some cases they have been formed by turning
over one end of the wire so as to make it double at that part and either previously
indenting one or both sides so that when doubled the eye shall be formed, or the eye
has been formed by means of a suitable pressing tool. According to another method
of manufacture jacquard needles or cross wires have been made of single wires with
slots or long eyes pressed or punched through the centre of the solid wire.
According to another method hitherto adopted by the said John Jardine such
jacquard needles or cross wires have been formed of three pieces, the piece, in which
the slot or eye is formed, being formed of sheet brass, wires being fastened thereto at
each end.
In all the above cases the jacguard needles or cross wires have been guided by
means of thin wires passed through their eyes or slots to keep them in position.
Our improved needle or cross wire is of very different construction as we make it
without a slot or eye through it and so form it that much stronger vertical guides or
supports can be used than there is room for with any of the Jacguard needles or cross
wires hitherto made.
The part of our improved needle or cross wire corresponding to the eye or slot of
an ordinary needle or cross wire is made by compressing between dies a piece of
round wire so as to form a flat part at the required place.

page_text: This flat part corresponds in length with that of the eye or slot of an ordinary
needle and it is about one third of the thickness of the wire and nearly double its
width.
The ends or stops regulating the length of the traverse of an ordinary needle or
cross wire are the two ends of the eye or slot; in our improved needle or cross wire
these stops are formed by again compressing the wire into two other flats at right
angles to that first mentioned, and one being at each end thereof, thereby forming the
required stops for the traverse of the needle or cross wire and also the shoulder
against which the spiral spring abuts when the needle or cross wire is acted upon by
the jacquard.
Our improved needle or cross wire passes through an eye made by bending flat wire
over a steel template so as to form a double cotter pin with a central slot of the width
of the template over which it is bent and pressed.
Thus the complete needle or cross wire is formed from one piece of wire without a
hole or slot through it, but having instead two flat places double the width of the wire
at right angles to each other, one flat passing through the slot in the double cotter
pin and the other flat resting on a cross wire each flat giving double the surface to
the support and guide of any ordinary needle or cross wire.
The double cotter is passed over the central flat of the needle, or cross wire, and the
cross support is placed under the flat at right angles to the above.
The double cotters are carried in the following manner. Two plates are perforated
with rectangular holes arranged in such manner that the distance between these holes
is exactly equal to the distance between the two sides of the cotter pin, that is to say
the width of the slot through which the needle or cross wire passes.
The top and bottom plates are fixed to the jacguard, the cotter pin is passed over
the division in the top plate, then over the central flat of the needle or cross wire and
finally over the division in the bottom plate, so that the cotter pin is kept open the
required distance by the divisions in the top and bottom plates between the rectangular
holes, the adjoining cotter pins being placed in like manner fill
up
the rectangular
holes, and by these means most secure and accurate guides are made for the needles
to pass through, the end holes on each side being made tight by half a cotter pin
being fixed in each of them.
Jacquard needles or cross wires formed, supported and guided as above described,
move freely, with less friction, are held more securely, are more steady and safe in
action, and are much less liable to get out of repair than any of the ordinary
needles.

page_text: We, JOHN JARDINE of Raleigh Street and CORNELIUS HENRY CRAWLEY of
Thrumpton Terrace. Briar Street, both in the Town and County of the Town of
Nottingham, Machinists, 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 has for its object improvements in Jacquard needles or cross wires
used in Jacquards applied to machines for making lace curtains and in other similar
Jacquards and also in the method of supporting and guiding the said needles or cross
wires.
Jacquard needles or cross wires as hitherto constructed have all been formed with
eyes or long slots through them; in some cases they have been formed by turning
over one end of the wire so as to make it double at that part and either previously
indenting one or both sides so that when doubled the eye shall be formed, or the eye
has been formed by means of a suitable pressing tool. According to another method
of manufacture Jacquard needles or cross wires have been made of single wires with
slots or long eyes pressed or punched through the centre of the solid wire.
According to another method hitherto adopted by the said John Jardine such
Jacquard needles or cross wires have been formed of three pieces, the piece in which
the slot or eye is formed being formed of sheet brass, wires being fastened thereto at
each end.
In all the above cases the Jacquard needles or cross wires have been guided by
means of thin wires passed through their eyes or slots to keep them in position.
Our improved needle or cross wire is of very different construction as we make it
without a slot or eye through it and so form it that much stronger vertical guides or
supports can be used than there is room for with any of the Jacquard needles or
cross wires hitherto made.
Our invention is represented in the accompanying drawings in which Figure 1 is a
side view and figure 2 is a plan of one of our improved needles or cross wires.
Figure 3 is a face view and figure 4 is a side view of one of our improved vertical
guides or supports, Figure 5 is a face view and figure 6 is a plan of a Jacquard spring
box and figures 7 and 8 are respectively a vertical longitudinal section and a plan of
parts.

page_text: a, represents our improved needles or cross wires and b, our improved vertical
guides or supports.
The part of our improved needle or cross wire a corresponding to the eye or slot of
an ordinary needle or cross wire is made by compressing between dies a piece of
round wire so as to form a flat part a' at the required place.
This flat part a corresponds in length with that of the eye or slot of an ordinary
needle and it is about one third of the thickness of the wire and nearly double its
width.
The ends or stops regulating the length of the traverse of an ordinary needle or
cross wire are the two ends of the eye or slot; in our improved needle or cross wire
these stops are formed by again compressing the wire into two other flats, a², a³ at
right angles to that first mentioned, and one being at each end thereof, thereby
forming the required stops for the traverse of the needle or cross wire and also the
shoulder against which the spiral spring cabuts, when the needle or cross wire is
acted upon by the Jacquard.
Our improved needle or cross wire passes through an eye made in vertical
guides by bending flat wire over a steel template so as to form a double cotter.
pin b with a central slot of the width of the template over which it is bent and
pressed.
Thus the complete needle or cross wire a is formed from one piece of wire without
a hole or slot through it, but having instead two flat places a', a², double the
width of the wire at right angles to each other, one flat a passing through the
slot in the double cotter pin and the other flat a resting on a cross wire d
each flat giving double the surface to the support and guide of any ordinary needle
or cross wire.
The double cotter 6 is passed over the central flat a of the needle or cross
wire a and the cross support d is placed under the flat a² at right angles to the
above.
The double cotters bare carried in the following manner. Two plates e. f. are
perforated with rectangular holes arranged in such manner that the distance between
these holes is exactly equar to the distance between the two sides of the cotter pin b,
that is to say, the width of the slot & through which the flat a¹ of the needle or cross
wire a passes.
The top and bottom plates, e. f. are fixed to the Jacquard, the cotter pin 6 is passed
over the division in the top plate e then over the central flat a' of the needle or cross
wire a and finally over the division in the bottom plate so that the cotter pin b is
kept open the required distance by the divisions in the top and bottom plates, e. f.
between the rectangular holes, the adjoining cotter pins being placed in like manner
fill up the rectangular holes, and by these means most secure and accurate guides are
made for the needles a to pass through the end holes on each side being made tight
by half a cotter pin b* being fixed in each of them.
Jacquard needles or cross wires a formed, supported and guided as above described
move freely, with less friction, are held more securely, are more steady and safe
in action and are much less liable to get out of repair than any of the ordinary
needles.
. 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
we claim is :
1. The combination of the improved Jacquard needle or cross wire a, vertical guide
or support b, and top and bottom plates c. f. constructed substantially as herein shown
and dribed and for the purpose stated

page_text: 2. The improved Jacquard needle or cross wire a formed from a single piece of
round wire with flats a¹, a², a³ substantially as herein shown and described and for
