IM- PROVEMENTS IN THE MANUFACTURE OF LACE IN TWIST LACE MACHINES
Year: 1878

page_text: LETTERS PATENT to Robert Maxton and Frederick James Perry, both of
St. Pierre-les-Calais, in the Republic of France, for the Invention of "IM-
PROVEMENTS IN THE MANUFACTURE OF LACE IN TWIST LACE MACHINES."
Sealed the 22nd March 1878, and dated the 7th January 1878.
PROVISIONAL SPECIFICATION left by the said Robert Maxton and Frederick
James Perry at the Office of the Commissioners of Patents on the 7th January
1878.
ROBERT MAXTON and FREDERICK JAMES PERRY, both of St. Pierre-les-Calais,
in the Republic of France. " IMPROVEMENTS IN THE MANUFACTURE OF LACE IN
TWIST LACE MACHINES."
According to our Invention we produce a net or ground as fine again as the
gauge of the machine, and with twist on all the pillars. We provide three warp
threads for each bobbin thread, either throughout or at the parts where the fine
net or ground is to be produced, and we work in the manner illustrated by the
annexed sketches.
In the sketches the bobbin threads are marked in yellow, and the warp threads
with which they twist continuously are marked in blue, whilst the two warp
threads which form the intermediate pillar are marked the one in red and the other
in black.
Figure 1 shows the way in which the threads are first laid by the machine, and
Figure 1 shows the way in which they are caused to form as they rise above
the points of the machine by a suitable adjustment of the tensions of the threads.
Figure 2 is a modification differing from Figure 1, in that there is more twist
upon the pillars between the crossings, for the amount of twist may be varied.

page_text: Figure 2 shows the way in which the work forms as it rises above the points.
The crossings of the net are here formed by the bobbin threads, the warp threads
marked in black being in this case sufficiently weighted to draw the bobbins out.
The extra threads of the warp, which form the additional pillars, are available to
produce finings in the figure.
SPECIFICATION in pursuance of the conditions of the Letters Patent and of
an Order of the Lord Chancellor, filed by the said Robert Maxton and
Frederick James Perry in the Great Seal Patent Office on the 24th July
1878.

In the sketches the bobbin threads are marked in yellow, and the warp threads
with which they twist continuously are marked in blue, whilst the two warp
threads which form the intermediate pillar are marked the one in red and the other
in black.
Figure 1 shows the way in which the threads are first laid by the machine by
means well known to machine lace makers, and Figure 1 shows the way in which
they are caused to form as they rise above the points of the machine by a suitable
adjustment of the tensions of the threads, also by means well known to machine
lace makers.
Figure 2 is a modification differing from Figure 1, in that there is more twist
upon the pillars between the crossings, for the amount of twist may be varied.
Figure 2 shows the way in which the work forms as it rises above the points.
The crossings of the net are here formed by the bobbin threads, the warp threads
marked in black being in this case sufficiently weighted to draw the bobbins out.
The extra threads of the warp, which form the additional pillars, are available to
produce finings in the figure.
What we claim is,―
First. As a new produce of the twist lace machine, lace or net having pillars
formed by two warp threads twisted together with right-hand and left-hand twist,
and alternating in the fabric with other pillars containing bobbin threads.

page_text: Second. The manufacture of lace in twist lace machines, substantially as described,
and represented in the annexed Drawings.
In witness whereof, I, the said Frederick James Perry, have hereunto set my
hand and seal, this Sixth day of July, in the year of our Lord One thousand
eight hundred and seventy-eight.
