I, JOHN WOOLLEY, of 256 Woodborough Road, Nottingham, Lace Maker, do
hereby declare the nature of my invention to be as follows:-
:-
In warp lace machines in which perforated steel bars, and a guide bar or bars
carrying the pillar threads are employed, working in combination with a latch needle
bar, or a bearded needle bar with a presser bar, a hook bar, a point bar working in
conjunction with the pillar bar and pushing the work back on the needles, or with
another point bar working under or over the steel bars and taking the threads from
the steel bars and delivering them to the hook bar.
Instead of the solid points working under or over the bars and taking the threads
from the steel bars and delivering them to the hooks. I employ instead of the solid
point a doubled point or sheath which is formed out of thin sheet steel having half its
width folded over on to the other half in such a way that the two sides lie parallel.
with each other and form a doubled point or sheath, the said doubled points or
sheaths enter the threads close under or close above the perforated steel bars according
to the construction of the machine, and convey the traversed fancy or other threads to
the hooks, the hooks entering the said doubled points or sheaths, the hooks in passing
through doubled points or sheaths gather the whole of the fancy or other threads from
them, and places them on the reverse side of the needle to that on which the beard or
latch is turned. The hooks coming within the doubled points or sheaths ensures the
delivery of the threads to the needles and thus enables me to employ a greater number
of top or bottom steel bars carrying fancy or other threads. The combined movements
of the hook bar, and the bar carrying the doubled points or sheath points are effected
by links and truck bearing levers operated by cams on the cam shaft, the several
movements of the other operating instruments I obtain in the usual way.
Dated this Eighteenth day of April 1887.

page_text: Figure 1 is a vertical sectional view showing the relative position of the operating
instruments in a warp lace machine in which the threads carried by the two sliding
steel bars at the back are supplied from spools, the perforated steel bars at the front
being also supplied with threads from spools, or from beams, in which I employ doubled
points or sheaths in conjunction with hooks.
Figures 2 and 3 are vertical sectional views showing the relative position of the
operating instruments in a warp lace machine in which the whole of the threads are
supplied from beams, in which I employ doubled points or sheaths in conjunction
with hooks.
Figure 4 shows a plan Figure 5 an underside view, and
Figure 6 a front end view of one of the doubled points or sheaths I employ.
In Figures 1, 2 and 3 perforated steel bars A are shown for traversing the fancy
threads, but bars carrying guides may be substituted for the two back bars carrying
the spool threads shown at Figure 1. The steel bars are shown above the
needles, but they may be placed below the needles, their position varying according to
the construction of the warp machine employed.
The figures also show bearded needles and a presser bar, but latch needles may be
employed instead, in which case the presser bar would not be required.
The corresponding parts in each Figure are indicated by the same letters where
necessary. In warp lace machines, in which perforated steel bars A are placed above
the needles, and a guide bar or bars B carrying the pillar threads are employed,
working in combination with a bar carrying latch needles, or bearded needles C with
a presser bar D, a bar carrying leads of hooks E, a bar carrying leads of points F
working in conjunction with the pillar bar or bars and pushing the work back on the
needles, or with another point bar working under or over the steel bars, according to
the construction of the machine, and taking the threads from the steel bars and
delivering them to the hooks E. Instead of the solid points carried by such other bar,
I employ doubled points or sheaths G (hereafter called sheaths only) cast in leads, each
sheath being formed out of thin sheet steel having half its width folded over onto the
other half in such a way that the two sides lie parallel with each other and form a
doubled point or sheath, the sides of which are sufficiently far apart to admit of the
easy passage of the hooks E, within them. The depths of the sheaths and the space
between their parallel sides will vary according to the guage of the machine in which
they are employed.

page_text: The movements of the sheaths in conjunction with the hooks are as follows:-
Immediately after the jacquard or jacquards have made a selection the sheaths G
rise from the position shown at Figure 3 to as high a point as the construction of the
machine will admit, and enter the threads under the steel bars as shown by the dotted
lines at Figure 1, they then descend into the position shown at Figure 2, and convey
the traversed fancy or other threads to the hooks, the hooks at the same time rise and
enter the sheaths moving towards the heads of the needles and in passing through the
sheaths gather the whole of the fancy or other threads from the sheaths and place
them on the reverse side of the needle to that on which the latch or beard is turned,
while the hooks are placing the fancy or other threads on the needles, the points F
assume the position shown at Figure 3 and when the hooks have fallen to their lowest
position, and are carrying the fancy and other threads round the heads of the needles,
the points F move upwards through the pillar threads and move backwards between
the needles, and the whole of the threads and the work back to the position shown at
Figures 2 and 3, the sheaths moving back to the position shown at Figure 3, such
movements being repeated at each course.
Thus by employing sheath points in conjunction with hooks, the delivery of the
threads to the needles is ensured and each thread is placed upon the needles according
to the selection of the jacquard or jacquards without being liable to be missed by the
hooks as heretofore.
The combined movements of the whole of the operating instruments are effected by
links and truck bearing levers operated by cams on the cam shaft in the usual way. I
am thus enabled to employ a greater number of top or bottom steel bars carrying fancy
or other threads than has heretofore been possible.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :-
The construction and employment of doubled points or sheaths working in
conjunction with hooks in warp lace machines, substantially as described and illustrated
in the Drawings annexed.
