CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN THE PREPARING OF COTTON AND OTHER FIBROUS MATERIALS FOR SPINNING."
Year: 1853

page_text: LETTERS PATENT to James Veevers, of Littleborough, in the County
of Lancaster, Cotton Spinner, and Henry Ashworth, of the same
place, Manager, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS TO BE EMPLOYED IN THE PREPARING OF
COTTON AND OTHER FIBROUS MATERIALS FOR SPINNING."
PROVISIONAL SPECIFICATION left by the said James Veevers and
Henry Ashworth at the Office of the Commissioners of Patents,
with their Petition, on the 8th March 1853.
We, JAMES VEEVERS, of Littleborough, in the County of Lancaster,
Cotton Spinner, and HENRY ASHWORTH, of the same place, Manager, do
hereby declare the nature of our said Invention of "CERTAIN IMPROVE-
MENTS IN MACHINERY OR APPARATUS TO BE EMPLOYED IN THE PREPARING OF
COTTON AND OTHER FIBROUS MATERIALS FOR SPINNING" to be as follows:-
Our improvements are applicable principally to drawing frames,
slubbing frames, and roving frames, and are designed for the purpose
of stopping such machines in the event of the cotton or other fibrous

page_text: material "lapping" upon the drawing rollers, or in case of either the
drawing rollers or calendering rollers becoming choked from that or
any other cause.
This object we effect by means of a lever bearing upon the ends of
ench set of top drawing rollers, and connected in a suitable manner
with any ordinary "knocking off" or stopping apparatus, in such
a manner that the rising of the said lever shall effect the stoppage of
the machine. It will be evident that if the "sliver," or "slubbing,"
should break, and begin to "lap" round any of the drawing rollers, the
consequent increasing diameter of the said roller will cause it (or its
corresponding top roller, if it laps on the lower roller) to rise, and by
raising the lever that rests upon the end of the same to stop the
machine. The result will be the same in the event of a larger quantity
of cotton than usual attempting to pass between the drawing rollers.
If the calendering rollers in the drawing frame become choked, the
increased resistance, preventing the spur wheels from turning, will
cause the top front drawing roller to rise, and by raising the said lever
to stop the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Veevers and Henry Ashworth, in the
Great Seal Patent Office, on the 8th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
JAMES VEEVERS, of Littleborough, in the County of Lancaster, Cotton
Spinner, and HENRY ASHWORTH, of the same place, Manager, send
greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of March, in the of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said James Veevers and Henry Ashworth, Her
especial licence that we, the said James Veevers and Henry Ashworth,
our executors, administrators, and assigns, or such others as we, the

page_text: said James Veevers and Henry Ashworth, our 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 "CERTAIN IMPROVEMENTS IN MA-
CHINERY OR APPARATUS TO BE EMPLOYED IN THE PREPARING OF COTTON
AND OTHER FIBROUS MATERIALS FOR SPINNING," upon the condition
(amongst others) that we, the said James Veevers and Henry Ashworth,
or one of us, by an instrument in writing under our hands and seals, or
the hand and seal of one of us, 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 Henry Ashworth, do hereby
declare the nature of our said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying drawing (that is to say):
Our improvements in machinery or apparatus to be employed in the
preparing of cotton and other fibrous materials for spinning, are princi-
pally applicable to drawing frames, slubbing frames, and roving frames,
and are designed for the purpose of instantly stopping such machines
in the event of the cotton or other fibrous material "lapping" upon the
drawing rollers, or callendering rollers becoming choked from that or
any other cause.
We effect this object by means of a lever bearing
upon the ends of each set of top drawing rollers, and connected by
suitable means to any ordinary "knocking off" or stopping motion or
apparatus, in such a manner that the rising of the said lever shall effect
the stoppage of the machine. In order more fully to illustrate our
Invention, and to shew in detail its practical application, we have
annexed hereunto a sheet of drawings, shewing very clearly the adapta-
tion of the same to an ordinary drawing frame. The drawing is made
about one half the actual size, and is marked with figures and letters of
reference corresponding with those in the following explanation thereof.

page_text: "
Fig. 1, represents a vertical section of part of an ordinary drawing
frame, with our improved apparatus applied thereto; and Fig. 2, is a
plan view of the same, as seen from above. a, a, is the roller beam;
b, b, is the roller stand; and c, c, are the drawing rollers; d, d, are the
callendering rollers; c, c, is a lever, capable of moving upon a suitable
fulcrum at f, and resting upon the ends of the top drawing rollers.
The lever e, e, is connected to another lever g, g, by means of a
link h, h. The lever e, e, is connected to the link h, h, in such a
manner as to be capable of being readily disconnected when required
for dofling, &c. The lever g,g, is fixed upon a shaft i, i, upon which
a lever k, k, is also fixed; to the other end of which lever k, k, a
catch, 1, is connected; m, m, is a lever mounted upon a contre at n,
and held in the position shewn in Fig. 1, by the catch 1, 1; 0, 0, are the
ordinary revolving wings," fixed upon a shaft p, p, to which one
half of a catch box, having inclined teeth, is attached, as usual. It
will be evident that, if the sliver should break and begin to "lap"
round any of the drawing rollers c, c, the consequent increasing
diameter of the roller will cause it (or its corresponding top roller, if
the "lapping" takes place upon the lower roller,) to rise, and by raising
the lever c, c, (which rests upon the end of the same,) release the
catch 1, 1, and allow the lever m, m, to fall into a perpendicular
position; which lever m, m, coming into contact with the revolving
wings 0, 0, will stop the revolution of the shaft p, p; thus
throwing the catch box out of gear, and consequently stopping
the machine. The result will be the same in the event of a larger
quantity of cotton or other fibrous material attempting to pass between
the drawing rollers. If the callendering rollers d, d, become choked,
either by the lapping of the sliver or from any other cause, the increased
resistance preventing the spur wheels 7, 9, (represented by the red circles
in Fig. 1,) from turning, will cause the front drawing rollers to rise,
and by raising the said lever e, e, to stop the machine. By the use or
employment of this improved apparatus we not only effect a great
economy of material by preventing the formation of waste, but also
obviate the breaking of the gearing, &c., hitherto so frequently caused
by the "lapping" and choking of the callendering rollers, as the machine
$6
"

page_text: cannot possibly get into motion again until the catches 1, 1, are put into
gear by means of the lever or handle 1, 1.
Having thus described the nature and object of our said Invention
of improvements in machinery or apparatus to be employed in the
preparing of cotton and other fibrous materials for spinning, together
with the manner of carrying the same into practical effect, we would
remark, in conclusion, that we claim as our Invention a lever resting
upon the ends of the drawing rollers, and connected to any suitable
disengaging apparatus, in such a manner that the raising of the said
lever, either by the lapping of the rollers or otherwise, shall stop the
evolutions of the machine.
In witness whereof, I, the said Henry Ashworth, have hereunto
set my hand and scal, the Seventh day of September, in the
year of our Lord One thousand eight hundred and fifty-three.
HENRY ASHWORTH. (L.S.)
