page_text: LETTERS PATENT to James Tomlinson, of Rochdale, in the County
of Lancaster, Machine Maker, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 30th April 1875, and dated the 3rd February 1875.
PROVISIONAL SPECIFICATION left by the said James Tomlinson at
the Office of the Commissioners of Patents, with his Petition, on
the 3rd February 1875.
•
I, JAMES TOMLINSON, of Rochdale, in the County of Lancaster,
Machine Maker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS
SUBSTANCES," to be as follows:-
My Invention is applicable to drawing frames and other machines of
the same nature in which slivers are delivered into cans, and it consists
of an improved combination of parts for stopping the machine when a
sufficient quantity of sliver has been delivered into the can.
The machinery consists of a lever hinged to the upper side of the
presser wheel forming part of the ordinary coiling apparatus by which

page_text: the sliver is delivered into the can, in this wheel is a hole to receive ä
curved edged disc fixed to the lever, the outer end of which is knife
edged. To the table in which the presser wheel revolves is hinged a
frame with a knife edged arm. To this frame is hinged a tumbler lever;
one arm of which forms an inclined plane, and another arm is placed
over a tube or guide in which the rod of an ordinary vibrator is free to
move. When the can is sufficiently filled the sliver acting on the disc
raises the lever and brings the knife edged end over the knife edged arm
of the frame and in contact with the inclined plane of the tumbler lever,
which in falling over brings the other arm into the tube or guide, where
it arrests the motion of the vibrating rod, and thus acts on the parts for
moving the driving strap from the fast to the loose pulley in the ordinary
manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Tomlinson in the Great Seal Patent Office
on the 2nd August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
TOMLINSON, of Rochdale, in the County of Lancaster, Machine Maker;
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the year
of our Lord One thousand eight hundred and seventy-five, in the Thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Tomlinson, Her special licence
that I, the said James Tomlinson, my executors, administrators and
assigns, or such others as I, the said James Tomlinson, 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 a
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES," upon
the condition (amongst others) that I, the said James Tomlinson, my
executors or administrators, by an instrument in writing under my,
or their; or one of their hands and seals, should particularly describe 3

page_text: 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 immc-
diately after the date of 'the said Letters Patent.
NOW KNOW YE, that I, the said James Tomlinson, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):-
My Invention is applicable to drawing frames and other machines of
the same nature in which slivers are delivered into cans, and it consists
in an improved combination of parts for stopping the machine when a
sufficient quantity of sliver has been delivered into the can.
The machinery consists of a lever hinged to the upper side of the
presser wheel forming part of the ordinary coiling apparatus by which
the sliver is delivered into the can; in this wheel is a hole to receive a
curved edged disc fixed to the lever, the outer end of which is knife
edged. To the table in which the presser wheel revolves is hinged a
frame with a knife edged arm. To this frame is hinged a tumbler lever,
one arm of which forms an inclined plane, and another arm is placed
over a tube or guide in which the rod of an ordinary vibrator is free to
move. When the can is sufficiently filled the sliver acting on the disc
raises the lever and brings the knife edged end over the knife edged arm
of the frame and in contact with the inclined plane of the tumbler lever,
which in falling over brings the other arm into the tube or guide,. where
it arrests the motion of the vibrating rod, and thus acts on the parts for
moving the driving strap from the fast to the loose pulley in the
ordinary manner.
And in order that my Invention may be fully understood, and
readily carried into operation, I will proceed to describe the accom-
panying Sheet of Drawings, in which Fig. 1 is an elevation of part of
an ordinary Drawing frame to which my improvements are applied';
Fig. 2 is a plan; and Fig. 3, a transverse section of the same; Fig. 4
is an elevation of part of the same.
a, a, are the drawing rollers; b, b, the calender rollers; c, the spoons
or guides for the slivers; d, the rocking shaft with feelers d'; c, the
roller beam; f, the coiler plate or table; g, the presser wheel; h,.the

page_text: _cover; and i, the top of the can, all these parts are made in the usual
manner. To the rocking shaft d is fixed the lever d², to which the
vibrating rod is hinged; the outer end of this rod passes through the
tube or double guide k, k¹, fixed to the side of the table f. To the upper
side of the ordinary presser wheel is hinged the lever 1, to which the
curved edged disc m is secured, and this disc fits casily in a hole in the
presser wheel; the outer end of the lever is knife edged, as shewn in
Fig. 4. The lever and disc mare counterbalanced by the lever o, on
which is an adjustable weight, the position of which can be varied
according to the amount of sliver that is to be deposited into the can.
To the plate of the tube or guide k is hinged the frame or bracket n,
which rests upon the edge of the table f, and to which the knife edged
arm n¹ is fixed; to the frame or bracket n is hinged the tumbler lever n²,
the short arm of which forms an inclined plane and rests upon the knife
edged arm n', as shewn in Fig. 4, and the other arm when down, as
shewn in dots in Fig. 3, comes against the end of the tube or guide ¹.
The mode of operation is as follows:-So long as the can is being
filled the knife edged end of the lever passes under the arm n', as shown
by the full lines in Fig. 4, and the vibrating rod moves to and fro
uninterruptedly in the guide or tube k, k¹, but when the can is full, and
the upward pressure of the slivers acting on the disc m is sufficient to
slightly raise the lever the knife edged end is brought into the position
shewn by dotted lines in Fig. 4, and as the presser wheel revolves the
knife edged end passes between the arm n' and the inclined plane of the
tumbler lever n², thereby causing the said tumbler lever to fall over and
to assume the position shewn in dots in Fig. 3; the upper end of the
tumbler lever then drops and closes the end of the tube or the hole in
the guide and arrests the motion of the vibrating rod j, by this means
the rocking shaft d is stopped, thereby bringing into operation the parts
for moving the driving strap from the fast to the loose pulley, and thus
stopping the machine until the full can is removed and an empty onc.put
in its place.
When the apparatus is at work the frame or bracket n fits in a slot in
the cover, as shewn by the full lines in Fig. 3; but when the cover
has to be removed for cleaning or other purposes the frame or bracket
is moved back on its hinge, as shown by dotted lines in Fig. 3, to allow
i

page_text: By means of this Invention the overfilling of the cans is entirely
prevented, and the labour of the attendants is reduced.
Having thus stated the nature of my Invention, and described a con-
venient mode of performing the same, I wish it to be understood that I do
not intend to limit myself to the details given as the same can be varied,
but what I claim is, the general combination and arrangement of the
parts forming a self-acting stop motion, which is brought into operation
when a sufficient quantity of sliver is coiled into a can, and particularly
the curved disc m, and the knife edged lever 1, and arm n², with the
tumbler lever n², acting in the manner and for the purposes described.
In witness whereof, I, the said James Tomlinson, have hereto set
my hand and seal, this Thirtieth day of July, One thousand eight
hundred and seventy-five.
