Improvements in or relating to Jacquards.
We, MARCEL BOUDARD, Jacquard Manufacturer, and CORNELIUS HENRY
CRAWLEY, Machinist, both of Peveril Works, Peveril Street, in the Borough of
Nottingham, do hereby declare the nature of this invention to be as follows:-
This invention relates more particularly to jacquards used in connection with
lace curtain machines, or looms for weaving, and it has for its main object the
reduction of the number of cards required and the reduction of the speed of the
jacquard or jacquards when used for producing on a lace machine work that is
known as double action, Swiss, combination, or Swiss with combination; or double
action Swiss or in a loom, what is known as double pick; or like effects.
The following description refers more especially to jacquards in connection with
lace curtain machines.
Hitherto in a lace curtain machine when any of the before mentioned classes of
work had to be made necessitating the jacks being sometimes partly and at others
wholly withdrawn from the threads each back motion of the machine if two
independent jacquards were employed, one of them would have to be worked twice
the speed of the other, and would make a full lift on each motion of the machine,
and the other would make a half lift on the back motion only.
Or, if a double jacquard was employed one part was made to give a full lift on
each motion of the machine and the other part, a half lift on the back motion only.
In both cases one jacquard or one part of a double jacquard will have to work
twice as fast as the other, and twice the number of cards will consequently be
required for one jacquard, or part of a double jacquard, as is required for the
other.
In carrying out our invention the jacquard selecting needles are formed with a
shoulder or enlargement at a suitable distance from the extreme end of the needle,
which shoulder forms a second selecting surface if used in connection with cards
punched with two different sized or shaped holes.
For example the shoulder is made of such a size and shape that it will pass
through the larger holes in the card and the selector will remain in what may be
called the first position if a smaller hole occurs in the card it will engage with the
shoulder and move the selector into the second position, if the card is blank it will
engage with the extreme end and move the selector into the third position.
By this arrangement the selector needles may be moved into one of three
positions instead of two and the vertical needles operated by the selector needles
will each take the position corresponding to its selector.
By the following arrangement the vertical needles in the second or intermediate
position may be lifted half the distance of those in the first position, those in the
third position remaining stationary.
The lifting grid is formed with either a double set of knives or lifters one set
being arranged below the other the distance between them being regulated
according to the difference of lift required, or a single set of lifters each formed
with two parts or lifting edges placed at different heights.
As the lifting grid commences its upward movement the upper part of the lifters
or upper set will engage with the vertical needles in the first position, at the same
time the card cylinder will commence to retire, so that by the time the lower part
of the lifters or lower set arrive at the point recently occupied by the upper set,

page_text: the vertical needles originally in the second position will have returned to the first
position and will engage with the lower set of lifters; the vertical needles in the
third position will miss both sets of lifters and will return to the first position as
the cylinder continues to retire.
With this system, if two jacquards are used, both may be worked at the same
speed one lifting on the front motion of the machine and one on the back, if a
double jacquard is used each part will in the same manner be worked as with two
jacquards and both sets of cards may contain the same number.
In punching the cards for the double motion each one is punched twice, first
for one sized hole and then for the other instead of punching extra cards for the
extra motion.
By the employment, in one grid working double action, of grid knives or lifters
having two parts or lifting edges at different heights, or a double set of lifters, or
two sets of lifters in independent grids operating at different times, in connection
with a jacquard with one or more cylinders, two vertical needles, or one vertical
needle provided with two books, bent in reverse directions may be used for each
selector needle.
With two sets of lifters in independent grids operating at different times, the
lifters in each set are arranged alternately and the vertical needles being disposed
between a lifter in each set, those in the first and second positions may be raised
by one set, and those in the second and third positions by the other set, those in
the first position in this case remaining stationary.
With two sets of lifters in a grid, with a double action the cylinder selects twice ;
first for the vertical needles in the first position then it partially retires and
again returns to hold the needles in the third position for the second set of
lifters.
In some cases the vertical needles may be arranged so that the action of the
card cylinder moves them towards the grid knives or lifters instead of holding
them away from it, as in the arrangements hereinbefore described, and the
manner of punching the card will therefore in this case be the reverse of that
described.
For example, if a vertical needle requires to be lifted as in the first position in
the previous arrangement, it will have to be moved by its selector needles to the
furthest extent, and this will be effected by a blank in the card; for the third
position it would have to remain stationary and this would be effected by a large
hole in the card; for the second or intermediate position it would have to be
moved half the distance, and this would be effected as in the previous arrangements
by a small hole in the card.

Improvements in or relating to Jacquards.
We, MARCEL BOUDARD, Jacquard Manufacturer, and CORNELIUS HENRY
CRAWLEY, Machinist, both of Peveril Works, Peveril Street, in the Borough of
Nottingham, 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 more particularly to jacquards used in connection with
lace curtain machines, or looms for weaving, and it has for its main object the
reduction of the number of cards required, and the reduction of the speed of the
jacquard or jacquards when used for producing on a lace machine, work that

It will be best understood by reference to the accompanying drawings, in
which―
Fig. 1. is a vertical cross section of a jacquard showing the application of the
nvention.
Fig. 2. is also a vertical cross section of a jacquard, showing a modified arrange-
ment, parts only of the jacquards being shown in both views.
Like letters indicate like parts throughout the drawings.
The following description refers more especially to jacquards used in connection
with lace curtain machines.
Hitherto in a lace curtain machine when any of the before mentioned classes of
work had to be made, necessitating the jacks being sometimes partly, and at others
wholly withdrawn from the threads, each back motion of the machine, if two
independent jacquards were employed, one of them would have to be worked twice
the speed of the other, and would make a full lift on each motion of the machine,
and the other would make a half lift on the back motion only.
Or if a double jacquard was employed one part was made to give a full lift on
each motion of the machine, and the other part, a half lift on the back motion
only. In both cases one jacquard, or one part of a double jacquard, will have to
work twice as fast as the other, and twice the number of cards will consequently
be required for one jacquard, or part of a double jacquard as is required for the
other.
In carrying out this invention the selecting needles A are formed with an
enlargement B, the end B¹ of which is a suitable distance from the extreme en: of
the needle, this shoulder B₁ forms a second selecting surface if used in connection
with pattern cards C punched with two different sized or shaped holes.
For example the enlargement B as shown is made of such a size that it will pass
through a large hole in the card and the selector needle as shown at A, and its
corresponding vertical needle D will remain in its normal, or what may be called
the first, position; if a small hole occurs in the card, it will engage with the
shoulder B and move the selector needle as shown at A2 and its corresponding
vertical needle D² into the second position, if the card is blank it will engage with
the extreme end of the selector needle and move it as shown at A3 and its
corresponding vertical needle D³ into the third position.
By the following arrangement the vertical needles D in the first or normal
position may be raised by one movement of a lifting grid a full lift, the needles D²
in the second or intermediate position raised half a lift, or any predetermined
reduced distance, whilst the vertical needles D³ in the third position remain
stationary.
The lifting grid E is formed with a double set of knives or lifters F, F¹ the
set F being arranged below the other, the distance between their upper edges
being regulated according to the difference required between the two lifts.
As shown in the drawings the card cylinder G has completed its inward
movement and the vertical needles D are disposed in the three different positions as
previously described, the lifting grid E has also commenced its upward movement
and the lifters F have engaged with the vertical needles D in the first position.
At this point the card cylinder G will commence to retire so that by the time the
lower lifters F' arrive at the point shown in dotted lines (normally. occupied by
the upper set F) the vertical needles D' in the second position will have returned
as shown in dotted lines to the first position, and will engage with the lifters F1.
The vertical needles D³ in the third position, will miss both sets of lifters, and will
return to their normal position without being lifted, as the cylinder G continues to
retire.
With this system, if two jacquards are used, both may be worked at the same
speed, one lifting on the front motion of the machine, and one on the back, if a

page_text: double Jacquard is used, each part, will, in the same manner be worked as with
two jacquards and both sets of cards will contain the same number.
In punching the cards for the double motion, each one is punched twice, first fo
one sized hole, and then for the other instead of punching extra cards for the extra
motion.
In a modified arrangement, shown in Figure 2, the vertical needles D arc
formed with two hooks H on opposite sides of the needles, with this arrangement
the lifters F F are disposed as shown, one on each side of the needles, so that the
needles D in the first position are lifted by the lifters F engaging with one
hook H, and those in the third position D³ by the lifters F1 engaging with the
opposite hook.
The vertical needles D2 in the second or intermediate position, in this case, are
not lifted..
In some cases in connection with vertical needles having two hooks H a grid
working double action provided with two sets of lifters F F or two sets of lifters
in independent grids operating at different times may be employed.
With two sets of lifters in a grid with a double action the cylinder selects twice;
first for the vertical needles in the first position, then it partially retires and again
returns to hold the needles in the third position for the second set of lifters.
By employing two sets of lifters in independent grids operating at different
times, the lifters in each set being arranged alternately and the vertical needles
being disposed between a lifter in each set, those needles in the first positions will
be raised by one set, and those in the third position by the other set.
In some cases the vertical needles may be arranged so that the action of the
card cylinder moves them towards the grid knives or lifters, instead of holding
them away from it, as in the arrangements herein before described, and the manner
of punching the card will therefore in one case be the reverse of that described
for the other.
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. In a jacquard such as described, a selector needle A, having a second
selecting surface, such as B' so that the said needle and its corresponding vertical
needle may be moved from their normal positions into one of two positions by
using pattern cards having holes of different shapes or sizes substantially as
described and illustrated in the accompanying drawings.
2. In a jacquard such as described, the combination with a selector needle A,
having a second selecting surface, such as B₁ of a lifting grid provided with two
sets of lifters such as F F substantially as described and illustrated in the accom-
panying drawings.
3. In a jacquard such as described a selector needle A having a second selecting
surface such as B₁ a lifting grid provided with two sets of lifters such as F F¹ the
lifters F engaging with the needles moved by the pattern card into the second or
intermediate position as the card cylinder retires substantially as described and
illustrated in the accompanying drawings.
4. In a jacquard such as described the combination with a selector needle A
having a second selecting surface such as B' of a vertical needle D formed with
two hooks such as H substantially as described and illustrated in the accom-
panying drawings.

having a second selecting surface such as B' of a vertical needle D formed with
two hooks H and a lifting grid with two sets of lifters such as F F¹ substantially
as described and illustrated in the accompanying drawings.
. 6. In a jacquard such as described the combination with a selector needle A
having a second selecting surface such as B₁ of a vertical needle D formed with

page_text: two hooks H and two independent grids, each provided with a set of lifters,.
each set operating independently of the other, substantially as herein described.
7. The combination and arrangement of parts constituting the complete
jacquard substantially as herein described and illustrated in the accompanying:
drawings.
