Improvements applicable to Jacquard Machines.
I, THOMAS WADSWORTH, of 181, Cotton Tree Road, Colne, in the County of
Lancaster, Loom Overlooker, do hereby declare the nature of this invention to
be as follows: :―
This invention relates principally to that class of Jacquard machine wherein
spring hooks are employed, and is designed to enable such machines to be
worked with half the number of needles or cross wires, hitherto employed in the
ordinary double-cylinder Jacquard machines, the cards being laced in the same
manner as for the ordinary double-cylinder Jacquard machines.
Hitherto the needles or cross wires of such machines have been provided with
a loop or eye through which the vertical hooks have passed, which causes such
hooks to be acted upon both at the forward and backward thrust of the
needles.
According to my invention I form two bends or angles upon each needle (at
any convenient part) in opposite directions, so that each needle acts twice, once
upon each of its respective hooks, one hook being pushed by one cylinder and
cards, and the other by the other cylinder and cards, according to the position
of the angles or catches on the needles.
For instance, according to the movement of the card cylinder, the first needle
will act upon the first hooks at its outward thrust and the sixteenth on its back-
ward thrust.
The second needle upon the 3rd and 14th hooks.
The third needle upon the 5th and 12th hooks.
The fourth needle upon the 7th and 10th hooks.
The fifth needle upon the 9th and 8th hooks.
The sixth needle upon the 11th and 6th hooks.
The seventh needle upon the 13th and 4th hooks.
The eighth needle upon the 15th and 2nd hooks.
The fronts of the needles are also cranked slightly out of a direct line near the
needle plate and are passed through suitable needle bars, and pins, which pre-
vent them from turning round.
I also place a series of double plates or grids on the top of the machine (running
at right angles to the needles) which hold the ends of the hooks rigidly in position,
thus causing the hooks to act as spring hooks, and by this means the usual boxes
and springs are dispensed with.
This invention is applicable to either long or short self-springing hooks.

Improvements applicable to Jacquard Machines.
I, THOMAS WADSWORTH, of 181, Cotton Tree Road, Colne, in the County of
Lancaster, Loom Overlooker, 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:—
This invention relates principally to that class of Jacquard machine wherein
spring hooks are employed, and is designed to enable such machines to be
worked with half the number of needles or cross wires, hitherto employed in the
ordinary double-cylinder Jacquard machines, the cards being laced in the same
manner as for the ordinary double-cylinder Jacquard machines.
Hitherto the needles or cross wires of such machines have been provided with
a loop or eye through which the vertical hooks have passed, which causes such
hooks to be acted upon both at the forward and backward thrust of the
needles.
My invention will be readily understood from the following description on
reference to the accompanying section or sketch of a double-cylinder Jacquard
machine made in accordance therewith.
I form three bends or angles a¹ a² a³ upon each needle (at the desired parts)
the bends a¹ a² being such that each needle acts twice, once upon each of its
respective hooks, one hook being pushed by one cylinder and cards, and the other
by the other cylinder and cards, according to the form and position of the angles
or catches on the needles; as shewn on the drawings the bends a¹ a² are so broad
as when pushed in one direction not to act on their respective hooks.
For instance, according to the movement of the card-cylinder, the needle n¹
will act upon the first hook 61 at its outward thrust in the direction of the
arrow 1 and the sixteenth on its backward thrust in the direction of the arrow 2.
The second needle 2 upon the 3rd and 14th hooks 62 14.
The third needle upon the 5th and 12th hooks b5 612.
The fourth needle n upon the 7th and 10th hooks 67 10.
The fifth needle 5 upon the ninth and 8th hooks 69 68.
The sixth needle nº upon the 11th and 6th hooks 611 66.
The seventh needle n upon the 13th and 4th hooks 13 4.
The eighth needle 78 upon the 15th and 2nd hooks 615 62.
Or the action of the needles may be reversed with regard to the hooks that is:
Needle n¹ may act on the 2nd and 15th hooks.
Needle n² may act on the 4th and 13th hooks.
Needle 3 may act on the 6th and 11th hooks.
Needle
Needle
may act on the 8th and 9th hooks.
may act on the 10th and 7th hooks.
may act on the 12th and 5th hooks.
Needle n may act on the 14th and 3rd hooks.
Needle n
Needle 8 may act on the 16th and 1st hooks.
The fronts of the needles are also cranked near the needle plate as seen at a³
and are passed through suitable needle bars xy and cross plates c or the like
prevent them from turning round.
I also place a series of double plates or grids or bars d on the top of the machine
(running at right angles to the needles) which hold the ends of the hooks 61 63 63
&c. rigidly in position, thus causing the hooks to act as spring hooks, and by this
means the usual boxes and springs are dispensed with.

page_text: This invention is applicable to either long or short self-springing hooks how-
ever the hooks may be made springing.
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: :-
1. The means substantially as herein before described and illustrated by the
annexed drawings for causing one needle to actuate two hooks in double cylinder
Jacquard machines.
2. The self springing hooks prolonged upwards and passed between or through
transverse bars at their top ends, substantially as hereinbefore described and
illustrated by the annexed drawings.
