Year: 1864

page_text: LETTERS PATENT to John Drabble, of Chesterfield, in the County of
Derby, Lace Manufacturer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF BOBBIN NET MADE ON BOBBIN NET OR TWIST LACE
MACHINES."
Sealed the 16th August 1864, and dated the 22nd February 1864.
PROVISIONAL SPECIFICATION left by the said John Drabble at the Office
of the Commissioners of Patents, with his Petition, on the 22nd February
1864.
I, JOHN DRABBLE, of Chesterfield, in the County of Derby, Lace Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF BOBBIN NET MADE ON BOBBIN NET OR TWIST
LACE MACHINES," to be as follows:-
My Invention has for its object the production of two distinct, ganges of
lace simultaneously on the same machine. Thus, say, for instance, one of the
meshes or nets may be eight-point net and the other sixteen-point net, or any
other required gauge net. The eight-point mesh or net has two warp threads
to two carriage threads, and the sixteen-point mesh or net has one warp
thread to one carriage thread, or two warp threads to one carriage thread, or
any required number of carriage threads to one or two warp threads, so as to
produce simultaneously any variety of gauges required on one and the same
machine.

by the said John Drabble in the Great Seal Patent Office on the
22nd August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN DRABBLE,
of Chesterfield, in the County of Derby, Lace Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of February, in the year of
our Lord One thousand eight hundred and sixty-four, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said John Drabble, Her special licence that I, the said John
Drabble, my executors, administrators, and assigns, or such others as I, the
said John Drabble, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "INPROVE-
MENTS IN THE MANUFACTURE OF BOBBIN NET MADE ON BOBBIN NET OR TWIST
LACE MACHINES," upon the condition (amongst others) that I, the said John
Drabble, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said John Drabble, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, reference being had to the accompanying Drawings and to the letters
and figures marked thereon, that is to say :-
My Invention has for its object the production of two distinct gauges of
lace simultaneously on the same machine. Thus, say, for instance, one of the
meshes or rets may be eight-point net and the other sixteen-point net, or any
other required gauge net. The eight-point mesh or net has two warp threads
to two carriage threads, and the sixteen-point mesh or net has one warp
thread to one carriage thread, or two warp threads to one carriage thread, or
any required number of carriage threads to one or two warp threads, so as
to produce simultaneously any variety of gauges required on one aud the same
machine.

page_text: DESCRIPTION OF THE DRAWINGS.
These Drawings represent small portions of two distinct gauged nets
considerably magnified; one of the meshes or nets, as previously indicated, may
be eight-point net and the other sixteen-point net, or any other required gauge
net. The eight-point mesh or net has two warp threads to two carriage threads,
as shown at Figures 1 and 2. Figure 1 represents the arrangement of the several
threads, the threads numbered 1, 4, 7, 10, 13, 16, and 19 represent the bobbin
threads, and the threads numbered 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, and 18
represent the warp threads, any number of bobbin threads and warp threads
being so arranged for each breadth, according to the width of such breadth,
and in any part or parts of each such breadth, which threads when so arranged
and worked up by the machine will produce an eight-point mesh or net, as
shown at Figure 2, in conjunction with sixteen-point mesh or net, as shewn at
Figure 4, on a sixteen point-machine; such sixteen-point mesh or net has the
threads arranged as shown at Figure 3, which represents one warp thread to one
carriage thread, the odd numbered threads representing the bobbin threads
and the even numbered threads representing the warp threads; but I some-
times arrange the threads so as to have one warp thread to one carriage
thread, or two warp threads to one carriage thread, or any required number of
carriage threads to one or two warp threads, so as to produce simultaneously
any variety of gauged nets required on one and the same machine; as, for
instance, on a sixteen-point machine I can produce a sixteen-point net, eight-
point net, four-point net, and twelve-point mesh or net on the same machine
and in each several or respective breadth made on such machine; and on a ten-
point machine I can produce a ten-point net, five-point net, and two-and-a-half-
point mesh or net; and on a fourteen-point machine I can produce a fourteen-
point mesh or net, a seven-point mesh or net, and a three-and-a-half-point-
mesh or net, so that I am enabled to produce any required ground of net as
before described with an edge of tabby weaving (or other woven or twisted
edge) and also a spot, sprig, or other ornament of tabby weaving with an open
work in the centre or other part of such spot, sprig, or other ornament of any
other gauged net or of the same gauged net as the ground of each breadth
of work produced by the machine.
Having now described the naturo of my said Invention and in what manner

page_text: the same may be performed, I declare that I claim the manufacture of
bobbin net in the manner herein described.
In witness whereof, I, the said John Drabble, have hereunto set my
hand and seal, this Twentieth day of August in the year of our Lord
One thousand eight hundred and sixty-four.
Witness,
GEO. JON. ROBINSON,
