IMPROVEMENTS IN APPARATUS
Year: 1874

page_text: LETTERS PATENT-to-Joseph Booth, of Radford Road, Now Basford,
Nottingham, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
Sealed the 16th October 1874, and dated the 19th August 1874.
PROVISIONAL SPECIFICATION left by the said Joseph Booth at the
Office of the Commissioners of Patents, with his Petition, on the
19th August 1874.
I, JOSEPH BOOTH, of Radford Road, New Basford, Nottingham, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR THE MANUFACTURE OF FABRICS IN TWIST LACE MACHINES," to
be as follows:-
This Invention has for its object improvements in apparatus for the.
manufacture of fabrics in twist lace machines.
In the manufacture of some descriptions of fabrics which I desire
to produce it is necessary to employ an edge bobbin carrying a
thick thread, and it is also necessary that there should not be any

page_text: bobbin omitted from the comb of the machine on the fabric side of the
edge bobbin. Such fabrics cannot be advantageously produced with the
ordinary bobbins or with any bobbin now in use or known, for any
ordinary bobbin which can be worked in this space would only hold a
very short length of stuff. The machine would be liable to be constantly
stopped to remove empty bobbins and substitute others in their place,
and the constantly varying temper of the thick bobbin threads would be
very inconvenient and detrimental.
Now according to my Invention I employ to carry the thick edge
bobbin thread a bobbin which is flat on one side (that which comes next
the fabric) and is bulged out on the other side so as to give room for
winding a full length of stuff upon the bobbin notwithstanding the
thickness of the thread which this bobbin carries. This enlargement of
the bobbin on one side necessitates the omission from the comb of the
machine of a bobbin in the space between the edge bobbin of one
breadth and the back edge of the next breadth, but to this there is no
objection.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Booth in the Great Seal Patent Office
on the 18th February 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
BOOTH, of Radford Road, New Basford, Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of August, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Booth, Her special license
that I, the said Joseph Booth, my executors, administrators, and
assigns, or such others as I, the said Joseph Booth, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter 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 "IMPROVEMENTS IN

page_text: APPARATUS FOR THE MANUFACTURE OF FABRICS IN TWIST LACE MACHINES," upon
the condition (amongst others) that I, the said Joseph Booth, 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 Joseph Booth, 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, that is to say :-
This Invention has for its object improvements in apparatus for the
manufacture of fabrics in twist lace machines.
In the manufacture of some descriptions of fabrics which I desire to
produce it is necessary to employ an edge bobbin carrying a thick
thread, and it is also necessary that there should not be any bobbin
omitted from the comb of the machine on the fabric side of the edge
bobbin. Such fabrics cannot be advantageously produced with the
ordinary bobbin or with any bobbin now in use or known, for any
ordinary bobbin which can be worked in this space would only hold a
very short length of stuff. The machine would be liable to be constantly
stopped to remove empty bobbins and substitute others in their place,
and the constantly varying tension of the thick bobbin threads would be
very inconvenient and detrimental.
Now according to my Invention I employ to carry the thick edge
bobbin thread a bobbin which is flat on one side (that which comes next
the fabric) and is bulged out on the other side so as to give room for
winding a full length of stuff upon the bobbin notwithstanding the
thickness of the thread which this bobbin carries. This enlargement of
the bobbin on one side necessitates the omission from the comb of the
machine of a bobbin in the space between the edge bobbin of one
breadth and the back edge of the next breadth, but to this there is no
objection.
In order that my said Invention may be most fully understood and
readily carried into offert Till

page_text: Figure 1 is a side view and Figure 2 an edge view of the bobbin with
its carriage. Figure 3 is a side view and Figure 4 a transverse section
of the bobbin removed from its carriage.
The bobbin consists of two plates, the one nearly flat like the side
plate of an ordinary bobbin, and the other bulged out as the Drawings
shew to afford additional thread space. The thickness of the bobbin is
thus made about double that of the carriage in which it is mounted.
The additional thread space thus provided causes the bobbin to
project beyond the carriage, as is seen in Figure 2, but the unusual
projection is carried entirely upon one side of the carriage, so that on
the other side there is no impediment to prevent another carriage
working in the next gate of the comb of the machine.
In some cases it may be advisable to make the bobbin of such a size
as to displace two other bobbins on one side of it, but nevertheless it
will still admit of a bobbin working in the next gate on the other side.
By these means I am enabled to carry a large quantity of thick thread
by a bobbin and carriage working close up to another bobbin and
carriage on one side of it, consequently I can produce fabrics for the
market which could not heretofore be economically manufactured.
I claim my improvements in apparatus for the manufacture of fabrics
in twist lace machines, substantially as described.
In witness whereof, I, the said Joseph Booth, have hereunto set
my hand and seal, this Thirteenth day of January in the year of
our Lord One thousand eight hundred and seventy-five.
