PROVIDIUNAL DE MOLTIVATION.
Apparatus for Automatically Indicating When and Where Threads
are Broken in Lace Machinery.
I, EDWARD COPE, of New Basford, Nottingham, Lace Manufacturer, do hereby
declare the nature of this invention to be as follows:-
In the Specification lodged by me in respect of an Application dated the 4th day
of November 1892, No. 19885, I described a method of automatically stopping
lace machines when warp or spool threads break. This was done by means of
lingoes attached to the threads so that when a thread broke the corresponding
lingoe fell through the sleys and became engaged with an obstruction on a bar
moving under the sleys thus putting into motion apparatus for stopping machine.
According to my present invention I employ in conjunction with such apparatus
an indicator traversed by means of an endless band close over the obstructions on
the moving bar. When a thread breaks and the lingoe attached to it drops and is
engaged by the moving bar, the indicator is intercepted by the lingoe when it
reaches that point thus showing the position of the broken thread. A bell or signal
electrically or mechanically worked may be added by which attention is called to
the machine.
The invention is also applicable in cases where the stopping apparatus is not
used the lingoes or other appliance carried by the thread stopping the indicator
when a thread is broken and causing either by electrical or mechanical means a
signal to be given by which it is known that a thread has broken.

COMPLETE SPECIFICATION.
Apparatus for Automatically Indicating When and Where Threads
are Broken in Lace Machinery.
I, EDWARD COPE, of New Basford, Nottingham, Lace Manufacturer, 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 :-
In the Specification lodged by me in respect of an Application dated the
4th day of November 1892, No. 19885, I described a method of automatically
stopping lace machines when warp or spool threads break. This was done by
means of lingoes attached to the threads so that when a thread broke the corre-
sponding lingoe fell through the sleys and became engaged with an obstruction on
a bar moving under the sleys thus putting into motion apparatus for stopping the
machine.
According to my present invention I employ in conjunction with such apparatus
an indicator traversed by means of an endless band close over the obstructions on
the moving bar. When a thread breaks and the lingoe attached to it drops and is

signal electrically or mechanically worked may be added by which attention is
called to the machine.

page_text: The invention is also applicable in cases where the stopping apparatus is not
used the lingoes or other appliance carried by the thread stopping the indicator
when a thread is broken and causing either by electrical or mechanical means a
signal to be given by which it is known that a thread has broken.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation showing some parts of a lace machine having my
invention applied to it and Figure 2 is a transverse section of the same.
Figures 3 and 4 are similar full sized views showing a few of the parts.
a are the threads supporting lingoes working in sleys -d are longitudinally
reciprocating racks which are arrested if a thread breaks and a lingoe consequently
drops thereby stopping the machine as is described in my former Specification.
e is an endless band working on the pulleys ff which are caused to revolve in
any convenient manner. g is a rod fixed to the band e and carrying an indicator h
at its end.
When a thread breaks its lingoe drops and comes into the track of the rod g
(as shown in Figures 1 and 2) thereby stopping the indicator at that point.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a lace machine the combination of lingoes supported by the threads and a
travelling indicator which is arrested when a thread breaks and a lingoe
consequently drops.
2. Apparatus for automatically indicating when and where threads are broken in
lace machinery substantially as described.
