Office of the Commissioners of Patents on the.6th December 1881.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent
Agents, Southampton Buildings, London. "AN IMPROVED APPARATUS FOR THE
MANUFACTURE OF PILLOW-LACE." A communication from abroad by Carl Jamnig,
of Vienna, Austria.
In pillow-lace made by hand, the production of a broad band forming the
pattern of the lace occupies a great deal of time.
The object of the present Invention is to provide means for performing this
work more rapidly by effecting the movement of the warp threads by mechanical
means.
The device or apparatus I employ for this purpose, and by which two sets of
warp-threads can be moved to and fro past each other will be hereinafter called a
thread mover, which consists of the following parts, viz. :—
A suitable number (usually from 8 to 12 as required) of two armed levers,
having at their angles a circular hole, and being provided at the top with an eye
through which the warp threads of one of the two sets pass.
Also another set of two armed levers equal in number to the other set, which
also have at their angles the circular hole of the same size, and are provided at
the top with the eye through which the warp-threads of the other of the two sets
pass.
Also a spindle upon which the above described levers are arranged in alternate
succession, this spindle passing through the above-mentioned holes at the angles of
the said levers.
Also pins or bars connecting all of the second set of levers with one another,
and pins or bars connecting all of the first set with one another.

page_text: Also two springs, one of which is fixed on either side of the apparatus, and
which serve to press the two sets of levers asunder.
The upper ends of the threads of the bobbins are passed through the eyes of the
levers, and fastened above to the ordinary lace-pillow.
When commencing to work a cross thread is passed between the two rows of
threads, the arms are thereupon pressed past each other, whereupon the first levers
with their threads come to the front, whilst the other levers with their threads go
behind, whereby the previously inserted cross thread is enclosed in a manner
similar to the process of weaving the threads, passing through the levers repre-
senting the warp threads, and the cross-thread representing the weft-thread.
A second cross thread is now passed between the two rows of thread in their new
position, and afterwards the two sets of levers which have been held together by
the person working with the apparatus aro released, whereupon by the pressure of
the springs the two sets of levers are returned to their original position, and thus
the second cross-thread will bo also woven in. These operations are repeated for
weaving in a third and fourth cross-thread, and so on as long as required.
It is obvious that without departing from the nature of this Invention the shape
or size of the levers may be varied, that the eyes may have any suitable form, and
that in place of the springs counterweights or equivalent devices for effecting the
return movement of the levers may be used.
I may combine with the holes or eyes in the lovers slots, whereby the threads
may be laid into instead of being drawn through the said eyes.

by the said William Robert Lake in the Great Seal Patent Office on the

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED APPARATUS FOR THE MANU-
FACTURE OF PILLOW-LACE." A communication from abroad by Carl Jamnig, of
Vienna, Austria.
In the manufacture of pillow-lace by hand, the production of a broad band
occupies a great deal of time. The object of the present Invention is to enable
this work to be performed more rapidly by effecting the movement of the warp
threads by mechanical means.
The device or apparatus I employ for this purpose and by which two sets of
warp-threads can be moved to and fro past each other will be hereinafter callod a
"thread-mover."
In the accompanying Drawing-
Figures 1 and 2 illustrate the method of carrying the said Invention.into
practice.
Figures 3, 4, and 5 represent a complete device or apparatus constructed
according to the said Invention.
Figures 6 and 7 represent part of the apparatus drawn to an enlarged scale.
According to the said Invention the thread mover is constructed in the following
manner, that is to say:-A suitable number (usually from eight to twelve as
required) of two-armed levers a, a, having at thoir angles the circular holo o are
provided at the top with eyes through which the warp threads of one of the two
sets pass. Another set of two-armed levers b, b, equal in number to the first set
also have at their angles the circular holes c of the same size, and are provided at
the top with the eyes j through which the warp-threads of the other of the two
sets pass. Upon a spindle & the above described levers a, a, and b, b, are arranged
in alternate succession, this spindle passing through the above-mentioned holes o at
the angles of the said levers. The pins or bars g, g¹, connect all of the second set
of levers b, b, with one another, and the pins or bars h, h¹, connect all of the first
set of levers a, a, with one another. Two springs i, i, one of which is fixed on
either side of the apparatus serve to press the two sets of levers a and b asunder.
The upper ends of the threads k, l, of the bobbins are passed through the eyes j
of the levers a, a, and b, b, and are fastened above to the ordinary lace-pillow. At
the commencement of the operations the mechanism has the position shewn in
Figure 1, that is to say, the levers a with the threads are behind, and the levers b
with the threads are in front; while in this position a cross thread is passed
between the two rows of threads. The arms or levers a and b are thereupon
pressed past each other until they assume the position shewn in Figure 2, that is
to say, until the levers a with their threads k come to the front, whilst the lovers b
with their threads 2 go behind, whereby the previously inserted cross thread is
enclosed in a manner similar to the process of weaving the threads, k and Z repro-
senting the warp threads, and the cross-thread representing the weft-thread.
A second cross thread is now passed between the two rows of thread in their new
position, and afterwards the two sets of levers a and b which have been held
together by the person working with the apparatus are released, whereupon by
pressure of the springs i, i, the two sets of levers a and b are returned to their
original position (shown in Figure 1), and thus the second cross-thread will be also
woven in. These operations are repeated for weaving in a third and fourth cross-
thread, and so on as long as required.

page_text: It is obvious that without departing from the nature of the said Invention the
shape or size of the levers a, a, and b, b, may be varied, that the eyes ; may have
any suitable form, and that in place of the springs i, i, other springs, counter-
weights, or equivalent devices for effecting the return movement of the levers may
be used. I may combine with the holes or eyes j in the levers slots, as shewn in
Figures 6 and 7, whereby the threads may be laid in instead of being drawn
through the said eyes.
Having tbus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
First. An apparatus for the manufacture of pillow-lace provided with two sets
of levers a, a, and b, b, carrying the warp-threads, and movable to and fro past
each other, substantially as and for the purposes set forth.
Second. In an apparatus for the manufacture of pillow-lace, the springs for the
purpose of pressing the levers asunder, substantially as set forth.
Third. In an apparatus for the manufacture of pillow-lace, the combination of
the holes or eyes in the levers with slots, as shewn in Figures 6 and 7, whereby
the threads may be laid in instead of being drawn through the said eyes,
substantially as set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and scal, this Sixth day of June, in the year of our Lord One
thousand eight hundred and eighty two.
