PROVISIONAL SPECIFICATION.
Improved Needles for Jacquards.
We, MARCEL TUQUET, MARCEL BOUDARD, Halifax Place, Nottingham, Lace
Designers, and CORNELIUS HENRY CRAWLEY, 14 Thrumpton Terrace, Briar
Street, Nottingham, Machinist, do hereby declare the nature of this invention to
be as follows:-
Each horizontal needle is flattened to form shoulders near the front end which
passes through the front needle plate, the shoulders resting upon the back of the
plate. At the back of the plate the needle is cranked to engage with a vertical
lifting needle of the jacquard in the usual way.
spring
The back end of the needle is passed into one of the perforations in a
plate, next the front of the spring plate the needle is flattened and formed with
shoulders on which the front end of a coiled spring rests, the back end of the spring
pressing on the front of the spring plate, the Hat part of the needle next the spring
lies and slides between horizontal supporting wires, in front of which the needle lies
and slides in a vertically slotted sley plate. We are thus enabled to dispense with
the cotter pins heretofore employed, and straining the needles when in action, and
we are enabled to remove or replace any horizontal needles without disturbing the
adjacent needles.

COMPLETE SPECIFICATION.
Improved Needles for Jacquards.
We, MARCEL TUQUET, MARCEL BOUDARD, Halifax Place, Nottingham, Lace
Designers, and CORNELIUS HENRY CRAWLEY, 14 Thrumpton Terrace, Briar
Street, Nottingham, Machinist, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
Figure 1 is a vertical sectional view showing the relative position of two needle
plates, a vertical sley plate and horizontal wires which support our improved needles
when employed in a double action jacquard.
Figure 2 shows in plan portions of the same with three improved needles.
Figure 3 shows a plan and side view of one of our improved needles employed in
a single action jacquard.
Figure 4 shows the cranked portion of the improved needles employed in a double
action jacquard and
Figure 5 the cranked portion of the improved needles employed in a single action
jacquard.
Each horizontal needle employed in a double action jacquard is flattened to form
shoulders A, see Figures 1 and 2 near the front end which passes through the front
needle plate of the jacquard, each needle is provided with a coiled spring E the
back end of which rests upon the shoulders A and the front end on the back of the
needle plate B.
At the back of the plate each needle is cranked as shown at
Figure 4 to engage with a vertical lifting needle of the jacquard in the usual way.

page_text: The back end of each needle is passed into one of the perforations in a back
spring plate C, next the front of the spring plate the needle is flattened and formed
with shoulders D on which the front end of à coiled spring E' rests, the back end
of the spring pressing on the front of the spring plate C.
The flat part of the needle next the spring lies and slides between horizontal
supporting wires F in front of which the needle lies and slides in a vertically slotted
sley plate G.
The coiled springs E and E¹ hold the needles in the position shown at Figures 1
and 2 ready to be pressed inwards by an unpunched portion of a card on the front
cylinder or the back cylinder in the usual way.
Each horizontal needle employed in a single action jacquard is flattened to form
shoulders A, shown at Figure 3, near the front end which passes through the front
needle plate B, the shoulders-resting upon the back of the plate beyond which each
needle is cranked as shown at Figure 5 to engage with a vertical lifting needle of
the jacquard in the usual way.
The back end of each needle is passed into one of the perforations in a back
spring plate C, in front of the plate the needle is flattened and formed with
shoulders D and provided with a coiled spring El the flat part of the needle slides
between supporting wires F and is held by a vertically slotted plate G in the same
way as the needles employed in a double action jacquard. The shoulders A being
pressed up to the back of the front needle plate B hold the needles in position to
be pressed inwards by an unpunched portion of a card on a cylinder at the front.
By the above means we are enabled to dispense with the cotter pins heretofore
employed-and-avoid straining the needles when in action. And after removing the
-back spring plate. Cony horizontal needle may be removed or replaced without
disturbing the adjacent needles.
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
1. The construction and employment of improved needles for double action-and-
single action jacquards arranged and operating substantially as described and
illustrated in the drawings annexed:
