Improvements in Twist Lace Machines and in the Production of a
Mechlin Net Fabric thereby.
I FREDERIC RAINFORD ENSOR of Park Terrace The Park Nottingham Amateur
Lace Inventor do hereby declare the nature of this invention to be as follows:-
In Mechlin net as at present made in twist lace machines there is one warp thread
and one carriage thread in each closing or twist. The warp threads which are
carried by one bar simply traverse two gates and pass from one to another of two
adjacent bobbin or carriage threads as represented by Figure 1 of the annexed
drawings.
In such net if a thread breaks when the fabric is on the dressing frame the
injury spreads over a great extent of fabric and the piece is liable to be
ruined.
By my invention I produce a Mechlin net where the warp threads traverse over
five or it may be a greater number of gates and therefore this fabric is not liable to
the defect before stated and is in other respects superior.
I make the front comb bar of the machine moveable and jog it one gate to and
fro. I also arrange the points not to take up at every movement as is usual but at
every alternate movement and the points enter when the carriages are in the well or
centre of the machine. I provide a complete complement of carriages and a warp
thread to each carriage thread.

page_text: The point bars dip and take up every two movements alternately over tops of
carriages at the even movements while the carriages are moving from back to front
and are in the well or centre of the machine and while their bobbin threads line
with and brush the warp threads with which they are at the time twisting
thus the front points will meet the carriage bobbin threads-the back points will
follow them.
In the drawings annexed Figure 2 further illustrates the action of the points in
taking up the twist. The full lines in this Figure represent warp threads and the
dotted lines the carriage threads. The dotted rectangles indicate the carriages and
bobbins from which the carriage threads are drawn. The crosses denote the entrances
of the points.
Figure 3 represents a portion of the Mechlin net fabric produced, the full lines, as
before, indicating warp threads, and the dotted lines carriage or bobbin threads; the
figures refer to the table of movements and the crosses indicate the entrances of
the points.
The arrangements in respect to the action of the points is an important feature
and is applicable when producing other not grounds.

page_text: 1, FREDERIC RAINFORD ENSOR of Park Terrace The Park Nottingham Amateur
Lace Inventor 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 Mechlin net as at present made in single tier twist lace machines there is one
warp thread and one carriage thread in each closing or twist. The warp threads
which are carried by one bar simply traverse two gates and pass from. one to another
of two adjacent bobbin or carriage threads as represented by Figure 1 of the drawings
left with the Provisional Specification.
In such net if a thread breaks when the fabric is on the dressing frame the
injury spreads over a great extent of fabric and the piece is liable to be
ruined.
By my invention I produce a Mechlin net where the threads traverse over five or
it may be a greater number of gates and therefore this fabric is not liable to the defect
before stated and is in other respects superior.
I make the front comb bar of the machine moveable and jog it one gate to and
fro. I also arrange the points not to take up at every movement as is usual but at
every alternate movement and the points enter when the carriages are in the well or
centre of the machine. I provide a complete complement of carriages and a warp
thread to each carriage thread.

page_text: The point bars dip and take up every two movements alternately over tops of
carriages at the even movements while the carriages are moving from back to front
and are in the well or centre of the machine and while their bobbin threads line with
and brush the warp threads with which they are at the time twisting thus the
front points will meet the carriage bobbin threads-the back points will follow
them.
In the drawings left with the Provisional Specification Figure 2 further illustrates
the action of the points in taking up the twist. The full lines in this Figure represent
warp threads and the dotted lines the carriage threads. The dotted rectangles
indicate the carriages and bobbins from which the carriage threads are drawn. The
crosses denote the entrances of the points.
Figure 3 of the drawings left with the Provisional Specification represents a portion
of the Mechlin net fabric produced, the full lines, as before indicating warp threads,
and the dotted lines carriage or bobbin threads; the figures refer to the table of
movements and the crosses indicate the entrances of the points.
The arrangements in respect to the action of the points is an important feature and
is applicable when producing other net grounds.
The requisite movement is obtained by gearing the cam shaft of the point bars so
that it is driven at half the usual relative speed.
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 :-
C
1. The production of Mechlin net fabric substantially as described.
2. In the production of Mechlin net fabric causing the bobbin threads and the
warp threads to traverse by the use substantially as described of a jogging comb bar
and a jogging warp bar and of points entering at alternate movements when the
carriages are in the centre.
3. The use substantially as described in producing net grounds of points entering
at alternate movements when the carriages are in the centre.
4. The novel Mechlin net substantially as shown by Figure 3 of the drawing in
which all the threads both bobbin and warp traverse.
