PROVISIONAL SPECIFICATION.
An Improved Double Action Jacquard.
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 jacquard consists of a pair of standards connected by two upper tie rods,
lugs project from one side of the standards upon which a square or oblong shaped
frame is bolted, which supports a lower sley in which the looped spring bottom ends
of vertical needles are free to rise and fall. The top ends of the vertical needles
are hooked, the whole of them being of the same length, the hooks of the odd
numbered needles are turned towards the front of the jacquard, and the hooks of the
even numbered needles are turned towards the back of the jacquard.
Two sleys are secured between the standards one at the front and the other at
the back, in which the front and back ends of double ended horizontal selecting
needles slide, each needle has a double ended crank formed in it to clip one pair of
vertical needles.
The horizontal needles are alternately selected by a card on a cylinder at the
front and another at the back of the standards.
The two cylinders revolve in bearing arms connected by a pair of horizontal rods
sliding in capped bearings projecting from the standards, the cylinders being
alternately partly revolved by clawkers, and the to and fro movements of the
cylinders being effected by links and levers operated by an excentric on a driving
shaft in the usual way.
The blades employed to lift the odd numbered vertical needles are carried by
plates attached to a frame sliding vertically provided with rods which rise and fall
in bearings formed in the standards.
The blades employed to lift the even numbered vertical needles are carried by
plates attached to a frame provided with rods which rise and fall in bearings
projecting from the inside of the standards.
Intermediately of the blades the plates are slotted vertically of such a length as
to allow of the free movements of the blades which lift the odd numbered needles
before named.
The vertical movements of the two frames and their blades are effected alternately
by means of rocking levers and connecting links operated by cams or excentrics.
A bottom grid below the standards is attached to one of the frames carrying
blades to lift the vertical needles.
Strings from the selecting jacks of the machine to which the jacquard is attached
are passed through the grid, above which the end of each string is tied to a short
folded string each end of which is connected to the looped bottom end of a vertical
needle.
We are thus enabled to produce double action work on a machine without
employing two separate jacquards.

An Improved Double Action Jacquard.
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
ascertained in and by the following statement :—
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a right side view of one of our improved double action
jacquards.
Figure 2 a plan of the same, in both figures the vertical lifting needles and the
horizontal selecting needles are omitted.
Figure 3 is an enlarged vertical sectional view of portion of the jacquard showing
the standard at the left end, two rows of blades to lift the vertical needles the
lower sley in which the looped ends of the vertical needles slide, and three sleys
which support the selecting needles.
Each jacquard consists of a pair of standards A connected by two tie rods A¹ the
feet of the standards being bolted to cross bars A' attached to the machine to which
the jacquard is applied.
Lugs project from one side of the standards upon which a frame B is bolted,
which supports a sley plate B¹ in each slot of the plate the looped spring bottom
ends of a pair of vertical needles C are free to rise and fall.
Five pair only of these needles are shown in the sectional view Figure 3, two
pair near the front of the jacquard and three pair near the back, the spring ends C¹
of each pair press upon each other above the sley plate B¹ and hold the top hooked
ends C of the needles in position to be lifted by two rows of blades.
The whole of the vertical needles are of the same length, the hooks of the odd
numbered needles are turned towards the front of the jacquard, and the hooks of
the even numbered needles are turned towards the back of the jacquard.
Two sleys are secured between the standards, one D at the front and the other D
at the back in which the front and back ends of horizontal selecting selecting
needles D2 slide.
Each needle is made flat for a portion of its length near the back end, such
flattened part slides between a vertical row of horizontal wires D' which prevent
the needles turning, the wires D³ are supported at each end and intermediately if
required by plates D' each attached at the top and bottom to cross bars D³ secured
to lugs projecting from the standards.
Each selecting needle has a double ended crank d formed in it to clip one pair of
vertical needles C, the horizontal needles D are alternately selected by the
unpunched parts of cards on a cylinder at the front and another at the back of the
standards.
The cards on the front cylinder E force back the selecting needles causing the
front cranes to press back the hooked ends of the odd numbered vertical needles
clear of the upper row of lifting blades F while the blades rise.
The cards on the back cylinder E¹ force forward the selecting needles, causing
the back cranks to press forward the hooked ends of the even numbered vertical
needles clear of the lower row of lifting blades G while the blades rise.
The cylinders E and E¹ "see Figures 1 and 2" revolve in bearing arms e and e
at each end, the bearing arms being connected by a pair of horizontal rods e e
sliding in capped bearings projecting from the standards. The cylinders being
alternately partly revolved, the front one by a clawker f and the back one by a
clawker each pulled down by a spring f in the usual way.
The to and fro movements of the cylinders are effected by links H hinged at the
back end to levers H' secured to and rocking with a shaft H2 the lever H at the
right end of the jacquard is provided with a slotted arm H* in which the upper end

page_text: of a link H may be adjusted, the lower end of the link is secured to the strap of
an excentric H carried by a driving shaft H of the machine to which the jacquard
is applied.
The blades F employed to lift the odd numbered vertical needles are carried by
plates F attached to a frame F provided with rods F3 which rise and fall in
bearings formed in the standards, an arm projects from each side of the frame F³,
each hinged to a link having its lower end hinged to a lever F' each lever being
secured to and rocking with a shaft F, at the back of the jacquard. The left end
of the shaft F is provided with a slotted arm F7 in which the upper end of a link FB
may be adjusted, the lower end of the link is secured to the strap of an excentric F
carried by a driving shaft He before referred to.
The blades G employed to lift the even numbered vertical needles are carried by
plates G' attached to a frame G provided with rods G' which rise and fall in
bearings projecting from the inside of the standards.
Intermediately of the blades F the plates F1 are slotted vertically of such a
length as to allow of the free movements of the blades G.
An arm projects from each side of the frame G each hinged to a link G', having
its lower end hinged to a lever G³ each lever being secured to and rocking with a
shaft G6 at the front of the jacquard.
The upper ends of the levers F and G' on each side of the standards are
connected by a link G' thus causing the upper and lower frames and their blades to
be alternately raised and lowered at every revolution of the excentric F³.
The rods G of the lower frame project below the standards where they are
attached to. the frame g carrying a wire grid of the usual construction "shown in
section at Figure 3."
Strings J from the selecting jacks or other instrument of the machine to which
the jacquard is attached are passed through the grid, above which the end of each
string is tied to a short folded string J' each of which is connected to the looped
bottom end of a vertical needle.
When the above described double action jacquard is applied to a twist lace
machine, the odd numbered needles are lifted by the top blades F when the bobbins
and carriages are in the back combs, and the even numbered needles are lifted by
the bottom blades G when the bobbins and carriages are in the front combs.
The jacquard above described is equally applicable to twist lace machines, warp
lace machines and looms.
We are aware that the several parts of the machine above described have been
combined in a variety of ways to form single or double action jacquards, we therefore
make no claim for such seperate parts.
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 vertical lifting needles C in pairs in each
slot of a sley plate B' each needle being provided with a spring end C¹ in double
action jacquards substantially as described for the purpose specified.
2. For connecting the levers F and G rocking with the shafts F and G* by
links G the rocking being effected by an excentric F substantially as described
and illustrated in the drawings annexed.
