IMPROVEMENTS IN THE MANU- FACTURE OF DOUBLE OR TUBULAR FABRICS IN WARP MACHINERY
Year: 1867

page_text: LETTERS PATENT to John Hemsley, of Melbourne, in the County of
Derby, Manufacturer, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF DOUBLE OR TUBULAR FABRICS IN WARP MACHINERY."
Sealed the 25th October 1867, and dated the 4th May 1867.
PROVISIONAL SPECIFICATION left by the said John Hemsley at the
Office of the Commissioners of Patents, with his Petition, on the
4th May 1867.
I, JOHN HEMSLEY, of Melbourne, in the County of Derby, Manufacturer,
.do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF DOUBLE OR TUBULAR FABRICS IN WARP MACHINERY," to be as
follows:-
This Invention has for its object improvements in the manufacture of
tubular or double fabrics in in double needle bar warp machinery.
In manufacturing double or tubular fabrics for gloves or other purposes in
double needle bar warp machinery they have been hitherto made by what is
well known in the trade as the "single lap." Now according to these improve-
ments such fabrics are made by means of the "double lap," which is also well
known in the trade and is not new when making single fabrics by means of
a single needle bar in ordinary warp machines, but such double lap has not
heretofore been employed when making double or tubular fabrics in double
needle bar warp machinery, where in the course of working comparatively

page_text: wide fabrics are connected together so as to form them into several narrow
breadths, such, for instance, as for the fingers of gloves. By "double lapping"
the threads on to the needles in working the course I am enabled to produce
a good plain fabric, glove, or other article by employing one guide bar to
each needle bar, each guide bar containing one full set of threads, whereas
ordinarily by single lap two guide bars each containing one full set of threads
has been used to each needle bar, so that a good effect is produced with half
the number of bars and half the number of threads usually employed in single
lap, although I do not confine myself to the number of bars or the number of
threads employed in carrying out my improvements.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hemsley in the Great Seal Patent Office on the
2nd November 1867.

TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, JOHN

greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of May, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Hemsley, Her special licence that I, the said John Hemsley, my
executors, administrators, and assigns, or such others as I, the said John
Hemsley, 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
THE MANUFACTURE OF DOUBLE OR TUBULAR FABRICS IN WARP MACHINERY," upon
the condition (amongst others) that I, the said John Hemsley, 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 Hemsley, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :--
In manufacturing double or tubular fabrics for gloves or other purposes in
double needle bar warp machinery they have been hitherto made by what is
well known in the trade as the "single lap." Now according to these im-
provements such fabrics are made by means of the "double lap," which mode
of lapping the threads on to the needles is also well-known in the trade and
is not new when making single warp fabrics by means of a single needle bar
in ordinary warp machines, but such double lap has not heretofore been
employed when making duplicate or tubular fabrics in double needle bar warp
machinery, where in the course of working comparatively wide fabrics are
made which may be connected, together where desired by suitable arrange-
ments of the guide bars and guides" actuated by jacquard, or other, pattern
surfaces as is well understood;, so as to form them into several narrow
breadths, such, for instance, as the fingers of gloves. By "double lapping"
the threads on to the needles in working the course I am enabled to
produce good plain fabrics, gloves, or other articles by employing
guide bar (or set of guide bars or slides combined) to each needle bar, each
guide bar (or set of bars or slides combined) containing one full set of threads,
one to each needle of the bar with which it works, whereas ordinarily by
single lap two guide bars each containing one full set of threads have been
used to each needle bar, so that according to my improvements by double
lapping the threads on to the needles a good effect is produced with half the
number of bars and half the number of threads usually employed in single
lap, although I do not confine myself to the number of bars or the number of
threads employed in carrying out my improvements.
one
From the previous description it will be readily understood by persons
acquainted with this class of machinery that whilst each set of guides of the
two guide bars (or sets of bars or slides combined), each carrying one full set
of threads, or one thread to each needle, continue to work with their respec-
tive needle bars by "double lapping" their threads on to the needles that two
separate breadths of warp fabric will be produced by the machine, viz., one
width from each of the needle bars employed; but when it is desired to make
tubular fabrics such, for example, as gloves, as is well understood in the
manufacture of such articles in this class of machinery, by connecting the two
fabrics together at the parts required for producing such articles, then those
guides of either set which are required to work with the needles of the
opposite ar for the above purpose are mounted upon independent slides com-
bined with the main guide bars, being actuated by means of jacquard or

page_text: other pattern surfaces, so as to cause their guides and threads to work alter-
nately or as required with the two needle bars (by means of the "double
lap") to connect the two fabrics together where required, and at their
selvages.
Having thus described the nature of my Invention, and the manner of
performing the same, what I claim is, the manufacture of double or tubular
fabrics in double needle bar warp machinery by employing one full set of
threads and guides only to each needle bar, such duplicate or tubular fabrics
being made according to my improvements by causing the guides to "double
lap" their threads on to the needles in the production of such fabrics, as
herein-before described.
In witness whereof, I, the said John Hemsley, have hereunto set my
hand and seal, this First day of November, in the year of our Lord'
One thousand eight hundred and sixty-seven.
