IMPROVEMENTS IN JACQUARD NEEDLES OR CROSS WIRES
Year: 1880

page_text: LETTERS PATENT to William Martin, of Kirks Factory, Russell Street,
Nottingham, Machinist, and John Hind, in the employ of the said William
Martin at the aforesaid Factory, for an Invention of "IMPROVEMENTS IN
JACQUARD NEEDLES OR CROSS WIRES."
PROVISIONAL SPECIFICATION left by the said William Martin & John
Hind at the Office of the Commissioners of Patents on the 5th November
1880.
WILLIAM MARTIN, of Kirks Factory, Russell Street, Nottingham, Machinist,
and JOHN HIND, in the employ of the said William Martin at the aforesaid
Factory. "IMPROVEMENTS IN JACQUARD NEEDLES OR CROSS. WIRES."
In making the horizontal selecting needle or cross wire for a jacquard, it is usual
to turn the end round, making a double wire at one end, and by a pressing tool
form a loop or slot about one and a half inches from the end, in which a cotter pin
is placed to steady the needle when the jacquard is at work, and prevent it from
moving too far either backward or forward. A spiral spring is placed on the needle
between the slot and a back plate, to ensure the return of the needle to its ordinary
position after being acted upon by the card, but our improvement consists in
punching or pressing in the centre of the wire an eye or long slot, similar to the eye
of a stocking needle or packing needle, through which the cotter pin passes, and by
placing a spiral spring on a single wire instead of a double wire, as it would be
when turned in the ordinary way to form the loop, we ensure an equal central
pressure from the spring to the eye or loop of the needle, and are also able with
using only a single wire to point it at the end, so as to give it a lead into the
spring plate, and so prevent a breakage with springs or needles, which often occur
when worked in the usual way.

WILLIAM MARTIN, of Kirks Factory, Russell Street, Nottingham, Machinist,
and JOHN HIND, in the employ of the said William Martin at the aforesaid
Factory. "IMPROVEMENTS IN JACQUARD NEEDLES OR CROSS WIRES."
This Invention consists of improvements in what are known as jacquard
selecting needles or cross wires.
In making the horizontal selecting needle or cross wire for a jacquard, it is usual
to turn the end round, making a double wire at one end, and by a pressing tool
form a loop or slot about one and a half inches from the end, in which a cotter pin
is placed to steady the needle when the jacquard is at work, and prevent it from
moving too far either backward or forward. A spiral spring is placed on the needle
between the slot and a back plate, to ensure the return of the needle to its ordinary
position after being acted upon by the card. Our improvement consists in punching
or pressing in the centre of the wire an eye or long slot, similar to the eye of a
stocking needle or packing needle, through which the cotter pin passes, and by
placing a spiral spring on a single wire instead of a double wire, as it would be
when turned in the ordinary way to form the loop, we ensure an equal central
pressure from the spring to the eye or loop of the needle, and are also able with
using only a single wire to point it at the end, so as to give it a lead into the
spring plate, and so prevent a breakage with springs or needles, which often occur
when worked in the usual way.
Fig. 1 on the annexed Drawing shews a jacquard selecting needle made in the
ordinary manner, and Fig. 2 shews a needle made according to our Invention.
Having now described the nature and object of our Invention, and also the
manner in which it is worked, we would have it distinctly understood that what
we claim as new and novel is,―
The manufacture and introduction of single wires with slots punched or pressed
in the centre of a solid wire for cotter pins, and used with or without spiral
springs, and known in the trade as selecting needles or cross wires in jacquard
looms, substantially as herein before described and shewn on the Drawing.
In witness whereof, we, the said William Martin and John Hind, have
hereunto set our hands and seals, this Third day of May, in the year of
our Lord One thousand eight hundred and eighty one.
