CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the County of Middlesex "IMPROVEMENTS IN TULLE OR LACE MACHINES
[communicated to him from abroad by Emile Davenière of Paris in the French
Republic]
The object of this invention is to enable, by the combined action of the "fine
bars" and the "stump bars" of tullo or lace machines, "Stop," "One," "Two," to
be performed at will in the same motion, by means of mechanical combinations
and devices to be presently explained.
The peculiarity of the invention consists mainly in making "one" in a
mechanical and reliable manner by the action of a novel mechanism called " picker
bar"
acting in combination with the "stump bar." In the following description I
will explain both the mode of operating according to this invention and the novel
appliances employed.
.
22
For effecting "Stop" I cause the articulated Jacks N° 19 and 19bis (Fig. 1 of
the acompanying drawings) to avoid the action of the "pumps" 10 and 12 by
closing the holes of the cards of the Jacquard cylinders 5 and 7, corresponding to
the wires 21 and 20. These wires in rising disengage the articulated Jacks
from the catches of the pumps 10 and 12, so that the Jacks 19, 19bis fall to "stop
as shewn at N° 9. The thread being passed through the stump bar. A Fig. 2 the
picker bar B remains to the right, in the notch reserved for its hook (the stump
bar and picker bar being independent of one another and capable of acting con-
jointly or separately): The thread being passed through the stump bar A and the
fine bar C is brought into an inclined position to the left by means of the motion

page_text: to the left of the fine bar consequent on the movement of the Jacks, so that the
thread is situated at the left hand corner of the stump bar, that is to say, at
"Stop" as shown at Fig. 2.
For effecting "Two" the articulated Jack 19, 19bis is moved to the right by the
"pump" N° 12 (example N° 11 Fig. 1) the hole of the card of cylinder 7 cor-
responding to the wire 20 being pierced. The thread is thereby inclined to the
right as at Fig. 3 and is brought into the right hand corner of the stump bar,
while the hook of the picker bar remains in the notch of the stump bar, as shewn.
For effecting "Two" the hole of the card of cylinder 5 may also be pierced
corresponding to wire 21.
For effecting "One" the Jack 19bis is made to avoid pump N° 12 by plugging
the hole of the card of cylinder N° 7 corresponding to wire N° 20 (Example No 10
Fig. 1), so that Jack 19 is free to be operated by the wire 21 (Examplo N° 10
Fig. 1) and the catch of the pump N° 10, which, acting only after the pump N° 12
gives time for the picker bar to descend so as to bring its hook contrally in the
hole of the stump bar (Fig. 4) before the action of the catch of pump N° 10. Tho
action of the Jack 19 for effecting "One" is as follows. As, by piercing the holo
of the card of cylinder 5, the wire 21 does not raise Jack 19, this is actuated by
pump No 10 which rises after pump N° 12, and consequently the fine bar con-
nected to 19 receives the same movement to the right that it would have received
from pump N° 12, so that the thread in being moved to the right thereby is
stopped in its motion by the picker bar which has been brought to the middle
position, as shewn, for effecting "One" before the movement of pump N° 10.. Thus
the thread is made to effect "One" by mechanical means, the whole of the stump
bar being at "Two." The picker bar in descending does not touch the threads
making "Two" by the action of pump N° 12, as the brass plate a fixed on the
stump bar (shewn detachod at Fig. 5) protects these threads. The books of the
picker bar being shorter than the thickness of the brass plate, the threads actuated
by pump N° 10 are enabled to make "One."
It will be evident that the stump bar and picker bar are susceptible of a number
of different combinations in their motions from right to left or from left to right,
allowing the making of "One" "Two" "Three" "Four" &c while the fine bars
have the necessary action for the inclinations of the thread.
In operating according to this invention the Jacquard of the fine bars is not
altered in any way, only the action thereof is divided into two. The picker bar
alone effects the stopping of the thread in the middle of the holo of the stump bar
for making "One as described, and the fine bar Jacquard only serves to move the
fine bars before and after the movement of the picker bar. Fig. 6 shews a portion
of the picker bar detached.
"
In the arrangement shewn at Fig. 1 the improvements consist mainly in pro-
viding a second Jack articulated to the one previously employed, and a corresponding
second Jacquard apparatus and pump.
The arrangement may be modified by superposing the Jacquard cylinders instead
of placing them side by side. Fig. 7 shews a back view of a modified form of
"pusher bar "D and corresponding "stump-bar" A in position for making "Stop,"
corresponding to the movement of the fine bar to the left. For making "One
the bars occupy the position shewn at Fig. 8, corresponding to the movement of
the fine bar to the right, and for making "Two" the bars occupy the position
shewn at Fig. 9, corresponding to the movement of the fine bar to the right.

CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the county of Middlesex "IMPROVEMENTS IN TULLE OR LACE MACHINES " A
communication to me from abroad by Emile Davenière of Paris in the French
Republic
The object of this invention is to enable, by the combined action of the "fine-
bars" and the "stump bars" of tulle or lace machines, "stop," "One," "Two," to
be performed at will in the same motion by means of mechanical combinations and
devices to be presently explained.
"
a
The peculiarity of the invention consists mainly in making
"
one in
mechanical and reliable manner by the action of a novel mechanism called
"picker-bar acting in combination with the "stump-bar." In the following
description, I will explain both the mode of operating according to this invention
and the novel appliances employed.
10
For effecting "stop," I cause the articulated Jacks, No 19 and 19 bis (Figs 1
and 1 bis of the accompanying drawings) to avoid the action of the "
and 12 by closing the holes of the cards of the Jacquard cylinders 5 and 7,
"pumps
corresponding to the wires 21 and 20. These wires, in rising, disengage the
articulated Jacks from the catches of the pumps 10 and 12, so that the Jacks 19,
19 bis fall to "stop" as shewn at No. 9. The thread being passed through the
stump bar A, Fig. 2, the picker bar B remains to the right, in the notch reserved
for its hook (the stump bar and picker bar being independent of one another and
capable of acting conjointly or separately). The thread being passed through the
stump bar A, the fine bar C is brought into an inclined position to the left by
means of the motion to the left of the fine bar consequent on the movement of the
Jacks, so that the thread is situated at the left hand corner of the stump bar, that
is to say, at "
stop as shewn at fig. 2. For effecting "Two," the articulated
Jack 19, 19 bis, is moved to the right by the pump No 12 (example No: 11 Fig. 1)
the hole of the card of cylinder 7 corresponding to the wire 20 being pierced.
The thread is thereby inclined to the right as at fig. 3 and is brought into the right
hand corner of the stump bar, while the hook of the picker bar remains in tho
notch of the stump bar, as shown.
"
For effecting "Two," the hole of the card of cylinder 5 may also be pierced
corresponding to wire 21.
For effecting "one," the Jack 19th is made to avoid pump No: 12 by plugging
the bole of the card cylinder No: 7 corresponding to wire N° 20 (Example No: 10
Figs 1 and 1) so that Jack 19 is free to be operated by the wire 21 (Examplo
No: 10 Fig 1.) and the catch of the pump N° 10, which, acting only after the
pump No 12 gives time for the picker bar to descend, so as to bring its hook
centrally in the hole of the stump bar (fig. 4) before the action of the catch of
pump No 10. The action of the Jack 19 for effecting "One" is as follows. As,
by piercing the hole of the card of cylinder 5, the wire 21 does not raiso Jack 19,
this is actuated by pump N° 10. which rises after pump N° 12, and consequently
the fine bar connected to 19 receives the same movement to the right that it would
have received from pump N° 12, so that the thread, in being moved, to the right
thereby is stopped in its motion by the picker bar which has been brought to the
middle position, as shown, for effecting "One" before the movement of
No 10. Thus the thread is made to effect "one" by mechanical means, the hole
pump

page_text: of the stump bar being at "Two." The picker bar, in descending, does not touch
the threads making "Two" by the action of pump No: 12, as the brass plate a,
fixed on the stump bar (shewn detached at fig. 5), protects these threads. The
hooks of the picker bar being shorter than the thickness of the brass plate, the
threads actuated by pump No 10 are enabled to make "one."
It will be evident that the stump bar and picker bar are susceptible of a
number of different combinations in their motions from right to left, or from left
""four" &c, while the fine
to right, allowing the making of "one," "two," "three
bars have the necessary action for the inclinations of the thread.
In operating according to this invention, the Jacquard of the fine bars is not
altered in any way, only the action thereof is divided into two. The fine bar
Jacquard does not serve to hold the thread which is being operated upon in tho
middle of the hole of the stump bar. The picker bar alone effects the stopping of
the thread in the middle of the hole of the stump bar for making
described, and the fine bar Jacquard only serves to move the fine bars beforo
and after the movement of the picker bar. Fig. 6 shews a portion of the picker
bar detached.
one 0.8
In the arrangement shown at Fig. 1, the improvements consist mainly in
providing a second Jack articulated to the one previously employed, and a
corresponding second Jacquard apparatus and pump.
The arrangement may be modified by superposing the Jacquard cylinders
instead of placing them side by side.
Fig. 7 shews & front view of a modified form of pusher bar, Fig. 8 shows the
back view thereof. Fig 9 shews the front view and Fig. 10 the back view of the
stump bar.

For making "stop" corresponding to the action of the fine bar to the left, the
'stump bar A and the pusher bar D occupy the position shewn in front view at
Fig. 11 and in back view at fig. 12
For making "one," which corresponds to the action of the fine bar to the right,
the stump bar A and the pusher bar D occupy the position shewn in front view at
fig. 13 and in back view at fig. 14.
For making "two," which corresponds to the action of the fine bar to the right,
the stump bar A and the pusher bar D occupy the position shewn in front view at
fig 15 and back view at fig. 16.
Having thus described the nature of the said invention and in what manner the
same is to be performed, as communicated to me by my foreign correspondent, I
claim in respect of tulle or lace machines with pusher action,
"
First: The use of the herein described picker-bar, the action of which, combined
with the stump bar, permits of "one being made in a mechanical and certain
manner, in the same movement as "stop" and "two."
Second: The use of the additional articulated Jacks, pumps, and Jacquards as
herein described with reference to figs. 1 and 1b of the drawings.
Third: The modified form of pusher bar herein described with reference to
Figs 9 to 16 of the drawings.
In Witness whereof I the said Charles Denton Abel have hereunto set my hand
and seal this twenty seventh day of December in the year of our Lord one
thousand eight hundred and eighty-three.
