IMPROVED ARRANGEMENTS OF DRAWING ROLLERS USED IN MACHINERY FOR PREPARING AND SPINNING FIBROUS
Year: 1867

page_text: LETTERS PATENT to Jacob Taylor, of Liverpool, in the County of Lan-
caster, Cotton Broker, for the Invention of "IMPROVED ARRANGEMENTS OF
DRAWING ROLLERS USED IN MACHINERY FOR PREPARING AND SPINNING FIBROUS
Sealed the 23rd July 1867, and dated the 26th January 1867.
PROVISIONAL SPECIFICATION left by the said Jacob Taylor at the
Office of the Commissioners of Patents, with his Petition, on the
26th January 1867.
I, JACOB TAYLOR, of Liverpool, in the County of Lancaster, Cotton Broker,
do hereby declare the nature of the said Invention for IMPROVED ÅRRANGE-
MENTS OF DRAWING ROLLERS USED IN MACHINERY FOR PREPARING AND SPINNING
FIBROUS MATREIALS," to be as follows:-
This Invention relates, first, to drawing rollers employed for fibrous
materials of short staples in which it is advisable to make the rollers of
small diameters, although hitherto they have not been used effectively on
account of their bending and liability to breakage by torsion. To overcome
these defects I place two series of covered, plain, or fluted rollers of small
diameters on a series of supporting rollers, and drive all the rollers by toothed
gearing, or the middle series by friction if required, instead of driving one
[Price 8d1

page_text: series of rollers by gearing and the top rollers by friction, as at present
adopted. By means of the supporting rollers the drawing rollers can be small
in diameter without danger of breaking,and fibrous materials of short staples
can be drawn and spun to high numbers of superior yarn without difficulty
Secondly, when drawing fibrous materials of long staples I use rollers of
larger diameter, and dispense with the supporting rollers, but drive all the
rollers by toothed gearing without employing friction.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jacob Taylor in the Great Seal Patent Office on the
25th July 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACOB
TAYLOR, of Liverpool, in the County of Lancaster, Cotton Broker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of January, 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 Jacob Taylor, Her special license that I, the said Jacob
Taylor, my executors, administrators, and assigns, or such others as I, the
said Jacob Taylor, 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
or "IMPROVED ARRANGEMENTS OF DRAWING ROLLERS USED IN MACHINERY FOR
PREPARING AND SPINNING FIBROUS MATERIALS," upon the condition (amongst
others) that I, the said Jacob Taylor, 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 Inven-
tion, 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 Jacob Taylor, 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 thereof, reference being had to the figures ou the accompanying

page_text: Sheet of Drawings, and to the letters of reference marked thereon (that is
to say) :-
This Invention relates, first, to drawing rollers employed for fibrous
materials of short staples, in which it is advisable to make the rollers of
small diameters, although hitherto they have not been used effectively on
account of their bending and liability to breakage by torsion. To overcome
these defects I place two series of covered, plain, or fluted rollers of small
diameters on a series of supporting rollers and drive all the rollers by toothed
gearing, or the middle pair of drawing rollers by friction if required, instead
of driving one series of rollers by gearing and the top rollers by friction, as at
present adopted. By means of these supporting rollers the drawing rollers
can be small in diameter without danger of breaking, and fibrous materials of
short staples can be drawn and spun to high numbers of superior yarn without
difficulty.
Secondly, when drawing fibrous materials of longer staples I use rollers of
larger diameter, and dispense with the supporting rollers, but drive either all
the rollers by toothed gearing, or the front rollers by toothed gearing and the
other rollers by gearing or friction, as may be required.
On the accompauying Sheet of Drawings Fig. 1 is a transverse section, and
Fig. 2 a front view of my improved system of small drawing rollers supported
by supporting rollers adapted for spinning machines when spinning fibrous
materials of short staples. a represents the small drawing rollers; b, the
supporting rollers; c, the back drawing rollers; and d, the toothed gearing.
Figs. 3, 4, 5, and 6 are similar views of larger drawing rollers without
supporting rollers, adapted for spinning machines when spinning fibrous
materials of longer staples. e represents the front and middle drawing rollers;
f, the back drawing rollers; and g, the toothed gearing. Fig. 7 is a transverse
section, and Fig. 8 a front view of still larger rollers without supporting rollers,
adapted for slubbing and intermediate machines. represents the front and
middle drawing rollers; i, the back drawing rollers; and k, the toothed
gearing. Figs. 9 and 10 are similar views of rollers adapted to drawing
frames. 7 represents the front drawing rollers which are driven by gearing;
m, the drawing rollers behind them, which will also be driven by gearing;
n, the rollers behind the rollers m, the top one of which may be driven by
gearing or friction; and o, the back rollers, the top one of which may also
be driven by gearing or friction.
The supporting rollers in Figs. 1 and 2, and the bottom rollers in the other
Figures extend the entire width of the machine, and the toothed rollers are
out on in halves and soldered or fixed in any desired manner.

page_text: Having now described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that I claim,-
First, the supporting rollers for supporting drawing rollers of small
diameters, and the system of driving the rollers by gearing.
And, secondly, the system of driving drawing rollers of larger diameters,
either altogether by gearing, or partly by gearing and friction, as all such
improvements are herein described and illustrated in the accompanying Sheet
of. Drawings.
In witness whereof, I, the said Jacob Taylor, have hereunto set my hand
and seal, this Twenty-third day of July, in the year of our Lord One
thousand eight hundred and sixty-seven.
Signed, sealed, and delivered by the
within-named Jacob Taylor, in the
presence of

Patent Agent,
Manchester.
