COMPLETE SPECIFICATION.
Improvements in Jacquards.
We MARCEL BOUDARD, Jacquard Manufacturer, and CORNELIUS HENRY
CRAWLEY, Machinist, both of Peveril Works, Peveril Street, 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
tatement:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a right side view of the framing of a jacquard with our improve-
ments applied thereto, portions of the right standard are broken away to show the
vertical sleys carrying the horizontal needles in section. Central portions of each
standard are also omitted, the length of the standards depending upon the number
of vertical needles required.
Figure 2 shows a front view of an improved flyer we employ at either or both.
ends of each card carrying cylinder.
Figure 3 shows an enlarged side view of the lower end of one pair of vertical
needles we employ.
We employ two sets of horizontal needles 1 and 2, at Figure 1 only an upper
and lower needle of each set are shown. One set of needles 1 are placed over the
second set 2. The needles 1 are selected by cards on an upper cylinder 3 at the
back of the jacquard, and the needles 2 are selected by cards on a lower cylinder 4
at the front of the jacquard. Each cylinder may be carried by a frame sliding on
rods secured to the standards in the usual way.
Or each cylinder may be carried by levers as shown at Figure 1, the in and out.
movements of the cylinders being effected as shown and described in the Complete
Specification of a former Patent applied for by us for Improvements in Jacquards
No. 5478, dated March 19th 1892.
Each cylinder is held down by a break lever 6 and spring in the usual way.
Each cylinder is revolved by a clawker or clawkers 7 each engaging with a flyer
the portion 7 of the said flyer being of less diameter than the diameter of the
cylinder 3, or the part 3 of the cylinder on which the break lever lies. The
reduced diameter of the flyer enables the cylinder to be revolved with one half the

set 1 and 2 are each cranked in the usual way to engage with one of each pair of
vertical needles 5, hooked at their upper ends to engage with the blades of one of
a pair of lifting grids operated in the usual way.
The cards carried by the cylinder 3 select one needle of each pair which has its
hooked upper end turned towards the cylinder 3.
The cards carried by the cylinder 4 select one needle of each pair which has its
hooked upper end turned towards the cylinder 4.
Jacquard card cylinders and needles arranged as described and shown may be
employed in conjunction with a twist lace machine to make ordinary work by
either cylinder being operated while the other cylinder remains stationary. To
make double action work both cylinders may be employed acting alternately.
When making Swiss or combination work either cylinder may be worked at twice
the speed of the other cylinder.
The whole of the vertical needles at the bottom are made of the shape shown in
side view at Figure 3 and are arranged in pairs in both sets.
Both needles of each pair are connected by short strings 5ª to the usual jacquard
string 5b.
The flyer 7 above described and shown at Figures 1 and 2 is equally applicable
to either or both ends of the cylinders of other jacquards.

page_text: 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 two sets of borizontal needles 1 and 2
engaging with the required number of vertical needles 5, the horizontal needles
being selected by cards carried by cylinders 3 and 4, each provided at either or
both ends with a flyer 7ª, reduced in diameter, substantially as described and
illustrated in the drawings annexed.
2. The construction and employment of a flyer at either or both ends. of any
jacquard card cylinder, the portion 7" of the said flyer being of less diameter than
the diameter of the cylinder 3, or the part 3 of the cylinder on which the break
lever 6 rests, substantially as described and illustrated in the drawings annexed.
Dated this Eighth day of February 1893.
