PROVISIONAL SPECIFICATION.
Improvements in or relating to Needles for Jacquards.
We WILLIAM TAYLOR STANLEY and WILLIAM ALFRED WASS, Machinists, both in
the employment of Messieurs Swift and Wass New Basford Nottingham Machine
Builders, do hereby declare the nature of this invention to be as follows:-
Instead of securing a coiled spring on and near the end of each needle which
enters the spring plate of a jacquard, we solder or otherwise secure one end
of an open coiled spring at the end of each needle, and enclose the spring
and end of the needle in a steel tube, closed at the outer end and slit a short
length at its open end on each side, the sides are then bent towards each
other, but will open out to admit the coiled spring, and then close upon the stem
of the needle. When in position in a jacquard the closed end of each tube presses
against an unperforated plate, thereby dispensing with a costly perforated spring plate
and avoiding the loss or misplacing of springs each time the plate is removed for
repairs or adjustment.

COMPLETE SPECIFICATION.
Improvements in or relating to Needles for Jacquards.
We WILLIAM TAYLOR STANLEY and WILLIAM ALFRED WASS, Machinists both in
the employment of Messieurs Swift and Wass New Basford Nottingham, Machine
Builders, 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows in plan a jacquard needle, steel tube, and portion of an unperforated
spring plate.
Figure 2 a side view showing the right end of a needle and a coiled spring
enclosed in a steel tube which with the imperforated spring plate are shown in
section.
Figure 3 is an enlarged sectional view showing the right end of a needle provided
with a cylindrical stud and a coiled spring enclosed in a steel tube.
Instead of securing one end of a coiled spring near the end of each needle,
that passes into a perforation in the spring plate of a jacquard in the usual way,
we solder or otherwise secure one end of an open coiled spring A as shown at
Figure 2 on the end of each needle nearest the spring plate of a jacquard, the spring
projects beyond the end of the needle, both being enclosed in a steel tube B the outer
end of which is closed at B₁. The inner end of the tube is slit on each side for a short
length at B2 the sides are then bent towards each other, but may be opened out to
admit the coiled spring and end of the needle, the inner end of the slit portions closing
upon the needle, but allowing the tube to slide freely on it.
Or we solder or otherwise secure a short cylindrical and pointed stud E on the
back end of each horizontal needle, and enclose it, and an open coiled spring A
in a steel tube B, "as shown at Figure 3" the outer end of which is closed at B¹.
The inner end of the tube is slit on each side as before described closing upon the
needle, but allowing the tube to slide freely on it, the stud E ensuring the tube B
being kept in a line with the needle. The interior of the inner end of the tube is
[Price fid]

page_text: bevelled to readily admit the pointed end of the stud, and the coiled spring lying loose
within the tube remains within it when the needle is drawn out of it, distortion of the
spring by removing the needle is thus prevented. In front of the tube the needle is
made flat and a slot formed in it at B³ to receive a cotter pin B to restrain the
traverse of the needle and in front of the slot the needle is cranked and bent to
engage with a vertical lifting needle D of the jacquard in the usual way. The front
end B³ of the needle passes through a front needle plate to be pressed back by the
card on the jacquard cylinder employed.
When in position in a jacquard the closed end of the tube on each needle presses
against an unperforated spring plate C, the spring holding the front end of the needle
to the card on the cylinder or in a hole punched in the card, where the card is not
punched the needle is pressed back, the spring A being compressed within the tube
allows the needle to move back and hold the upper hooked end of the lifting needle
clear of the lifting grid in the usual way.
We are thus enabled.to dispense with the costly perforated back spring plate
heretofore employed and by substituting a solid plate, the loss or misplacing of
springs is prevented each time the back plate is removed for repairs or adjustment.
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 :-
The addition of a tube B containing an open coiled spring A projecting beyond the
back or outer end of each horizontal needle operated on by the cards in a jacquard.
The said tube B having its back end closed and resting upon an unperforated spring
plate (substantially as described and illustrated in the drawings annexed.
