Year: 1856

page_text: LETTERS PATENT to James Dickinson, of Blackburn, in the County of
Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS USED IN THE PREPARATION OF COTTON OR OTHER
FIBROUS SUBSTANCES FOR SPINNING."
Sealed the 5th May 1857, and dated the 8th November 1856.
PROVISIONAL SPECIFICATION left by the said James Dickinson at the
Office of the Commissioners of Patents, with his Petition, on the 8th
November 1856.
I, JAMES DICKINSON, of Blackburn, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY OR APPARATUS USED IN THE PREPARATION OF COTTON OR OTHER
FIBROUS SUBSTANCES FOR SPINNING," to be as follows:-
My said Invention consists in applying to the drawing frame an apparatus
for the purpose of preventing the breakage of the "coiler," as well as loss of
time and material employed by stopping the machine whenever the can or
coiler containing the sliver drawn becomes unduly filled and pressed. On the
coiler plate I place one side or end of a double lever or beam moving on a
fulcrum connected to the framework, the other side of the lever passes forward
to the front of the machine, its extreme end being bent or hooked down so as
to catch a lever or projection on the usual reciprocating shaft; one arm of
the double lever being longer than the other thereby giving the hook a longer
traverse than the part which rests on the coiler plate; but the arms are
balanced so as to be easily influenced by the pressure of the slivers in the

page_text: coiler, the hook arresting the motion of the reciprocating shaft and stopping
the machine. The nature of this Invention will be clearly understood by
reference to the accompanying outline Drawing, in which a represents the can
of the coiler; b, the coiler plate; c, the reciprocating shaft; d, tho cotton or
material above the top of the can; e, the double lover or beam; f, the hook; s
9, the fulcrum; and h the lever or projection on the reciprocating shaft, so
that when the car becomes full it raises the plate band deflects the book f
arresting the shaft c, thereby stopping the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Dickinson in the Great Seal Patent Office on the
7th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
DICKINSON, of Blackburn, in the County of Lancaster, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Eight day of November, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Dickinson, IIer special license that I, the said James Dickinson,
my executors, administrators, and assigns, or such others as I, the said
James Dickinson, 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 night 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 MACHINERY
OR APPARATUS USED IN THE PREPARATION OF COTTON OR OTHER FIBROUS SUBSTANCES
FOR SPINNING," upon the condition (amongst others) that I, the said James
Dickinson, 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 bo
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 James Dickinson, 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 state-
ment (that is to say):-

page_text: I apply to the drawing frame an apparatus for preventing the breakage of
the coiler or damage to the sliver, and the loss of time and material consequent
thereon, the said apparatus causing the frame or machine to be stopped when
the can containing the sliver becomes sufficiently or unduly filled and pressed.
The construction and application of the said apparatus is as follows:-On the
coiler plate I place one side or end of a double lever or beam moving on a
fulcrum connected to the frame of the machine, the other side or end of the
said lever passing forward to the front of the frame or machine, its extreme
end being bent or hooked so as to catch a lever or projection on the usual
reciprocating shaft. I make one arm of this double lever longer than the
other in order to give the hook a longer traverse than the part which rests on
the coiler plate, but the arms are balanced so as to be easily influenced by the
pressure of the slivers in the coiler, which pressure, by raising the coiler plate
and depressing the hook, arrests the motion of the usual reciprocating shaft
and stops the machine; or, I place upon the coiler plate a projection or holder
for the purpose of holding a catch, bolt, or slide, one end of which supports a
short lover or pin placed above a long arm or lever fixed to the usual rocking
or reciprocating shaft, so that when the can becomes sufficiently or unduly
filled, the projection or holder escapes from the catch, allows tho bolt to give
way, and releases the short lever or pin, which falling in the way of the lever
on the reciprocating shaft arrests its motion thereby stopping the machine.
The manner of carrying my said improvements into practical effect will be
clearly understood by reference to the accompanying Sheet of Drawings and
the letters of reference thereon, in which Fig. 1 is a transverse section of a
drawing frame, with the coiler having my improved stop motion attached,
and Fig. 2 is a modification of the same, the letters referring to each Fig.
separately.
In Fig. 1, a represents the can; b, the coiler plate; c, the reciprocating
shaft; and d the sliver above the top of the can. The double lever or
beam e is hooked at f, weighted or balanced at g, and works upon the
fulcrum h, which is attached to the framework i. Upon the reciprocating
shaft is the projection or lever k placed in a line with the hook f, so that
when the can becomes full and the coiler plate raised, the said hook f
becomes depressed, and seizing the projection or lever k on the reciprocating
shaft c stops the machine. In Fig. 2 the arrangement is somewhat different,
being a modification of the aforesaid apparatus, but the raising of the coiler
plate is still the first means of stopping the macbine as in the former example.
In this. Fig., a represents the can; b, the coiler plate; c, the reciprocating
shaft; and d the sliver. e are supports connected to the frame of the machine

page_text: upon which is the slide or bolt f having a notch or catch g. On the coiler
plate is the projection or holder h which holds the said slide or bolt when tho
coiler plate is not lifted up. At the same time one of the ends of the slide or
bolt also supports a short lever or pin i placed above the long arm or lever k
which is fixed to the rocking or reciprocating shaft c. When the can is
sufficiently or unduly filled, the projection or holder h escaping from the notch
or catch g on the slide or bolt f, which slide or bolt is then propelled in the
direction of the arrow by means of the spring 1, thereby no longer supporting
the short lever or pin i, which consequently falls down as shewn by the dotted
lines, and comes in contact with the long arm or lever k, obstructing the
motion of the reciprocating shaft c, and stopping the frame or machine. It
will be evident to all persons conversant with machinery used for preparing
fibrous materials to be spun, that this my improved stop motion is applicable
to other machines than the drawing frame, as the doubling frame, carding
engine, and in fact all machines where the coiler is or may be used.
Having thus fully described the nature of my said Invention and the manner
in which the same is to be performed, I desire it to be distinctly understood
that I do not confine myself to the exact details herein set forth, nor merely
to the two methods I have, described for arranging the apparatus which is to
be acted upon by the coiler plate, as such levers or slides may be varied or
modified to an almost indefinite extent; but I claim the use and arrangement
of levers or slides actuated by the rising of the coiler plate when the can
becomes sufficiently or unduly filled with sliver, the said levers, slides, or their
equivalents passing across the machine and acting upon the reciprocating shaft,
moving the driving strap from the fast to the loose pulley and stopping the
motion of the frame or machine, as such improvements are herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said James Dickinson have bereuuto set my
hand and seal, this Sixth day of May, in the year of our Lord One
thousand eight hundred and fifty-seven.
JAMES DICKINSON. (L.B.)
