Year: 1854

page_text: LETTERS PATENT to John Hackett, of Derby, in the County of Derby,
Manufacturer, for the Invention of "COVERING INDIA-RUBBER THREAD,
WHETHER VULCANIZED OR OTHERWISE, WITH SEWING SILK AND WITH OTHER
ARTICLES."
Scaled the 16th January 1855, and dated the 20th July 1854.
PROVISIONAL SPECIFICATION left by the said John Hackett at the
Office of the Commissioners of Patents, with his Petition, on the 20th
July 1854.
I, JOHN HACKETT, of Derby, in the County of Derby, Manufacturer, do
hereby declare the nature of the said Invention for "COVERING INDIA-RUBBEE
THREAD, WHETHER VULCANIZED OR OTHERWISE, WITH SEWING SILK AND WITH OTHER
ARTICLES" to be as follows:-
My Invention consists in covering india-rubber threads, whether vulcanized
or otherwise, with sewing silk, or silk twisted in the same or in a similar
manner as sewing silk, with not less than five turns or twists to the inch,
or with mohair, either single or of two or more threads twisted, together, or
with mohiar and silk combined, or with mohair and silk twisted together,
or with alpaca yarn, either single or of two or more threads twisted together,
or with linen yarn or thread, or with chenille. I also propose to cover. a
number of india-rubber threads together, so as to form a narrow elastic web.
The manner of covering the single cords is as follows:-I cover the bare

page_text: india-rubber thread by the use of a braid machine, such as is generally used
for that purpose; or I cover it by the use of a machine which wraps the
material round the india-rubber thread; or I first cover the india-rubber thread
with cotton, by using a so-called covering machine, and I afterwards cover it
with any of the above-named materials by using a braid machine.
When two or more threads are to be covered to make a web, or what is
termed a "sandling," I cover them either with one or other of the above-
named materials by using a braid machine, the same as is now used for
covering the ordinary braid or sandling; or if I wish to make the sandling
web in the loom, I place two or more threads of any of the above-named
materials between every thread of india-rubber in the warp, and use as weft
or shute, any material I think proper. In making gusset webs. or brace webs,
or belt webs, I use the warp threads 'in a similar manner to that in which I
use the warp threads in the sandling webs when made in the loom. In
making frill or garter webs, I adopt the same method in the plain part as that
which I adopt in the manufacture of the brace and gusset webs, except as
regards the warp which is to make the frill, which I make of any material I
choose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hackett in the Great Seal Patent Office on the 19th
January 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HACKETT, of Derby, in the County of Derby, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, er heirs and successors, give and grant unto me,
the said John Hackett, Her special licence that I, the said John Hackett,
my executors, administrators, and assigns, or such others as I, the said
John Hackett, 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 "COVERING INDIA-
RUBBER THREAD, WHETHER VULCANIZED OR OTHERWISE, WITH SEWING SILK AND
WITH OTHER ANTICLES," upon the condition (amongst others) that I, the said

page_text: John Hackett, by an instrument in writing under my hand and seal, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Hackett, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My Invention consists in covering india-rubber thread, whether vulcanized
or otherwise, with sewing silk, or silk twisted in the same or in a similar
manner to sewing silk, with not less than sixteen turns to the inch, or with
mohair and silk twisted together, or with linen thread, or with chenille.
The manner of covering single cords of india-rubber thread is as follows:-
I cover the bare india-rubber thread by means of a braid machine, such as
is in general use; or I cover it by means of a machine that wraps the
material round the india-rubber thread; or I first cover the india-rabber
thread with cotton, by means of a so-called covering machine, and I after-
wards cover it with any of the above-named materials by means of a braid
machine.
When two or more threads are to be covered to make a web, or what is
termed a "sandling," I cover them either with one or other of the above-
named materials by means of a braid machine, such as is now used for covering
braid or sandling, of the ordinary make; or if I wish to make the sandling"
web in the loom, I place two or more threads of any of the above-named
materials between every thread of india-rubber, either bare or covered in the
warp, and I use as weft or shute any material I think proper. In making
gusset webs, or brace webs, or belt webs, I use the warp threads in a similar
manner to that in which I use the warp threads in the sandling webs when
made in the loom.
In making frill or garter webs, I adopt the same method in the plain part
as that adopted in the manufacture of brace and gusset webs, except as regards
that part of the warp which is to make the frill, and this I make of any
material which I may consider most suitable.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that what I claim is,―
First, the covering of india-rubber thread, whether vulcanized or other-
wise, with sewing silk and with other materials of the description herein-before
mentioned.

page_text: And, second, the employment of india-rubber thread, covered, as herein-
before described, for the manufacture of web of not more than three inches
wide.
In witness whereof, I, the said John Hackett, have hereunto set my
hand and seal, this Seventeenth day of January, One thousand eight
hundred and fifty-five.
Witness,
GEO. JON. ROBINSON,
Patent Agent,
Nottingham.
