Year: 1867

page_text: LETTERS PATENT to Robert Hyde Barton, of Chorley, in the County of
Lancaster, Spinner and Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN THE PREPARATION OF COTTON
AND OTHER FIBROUS MATERIALS."
Sealed the 17th September 1867, and dated the 18th June 1867.
PROVISIONAL SPECIFICATION left by the said Robert Hyde Barton at
the Office of the Commissioners of Patents, with his Petition, on
the 18th June 1867.
I, ROBERT HYDE BARTON, of Chorley, in the County of Lancaster, Spinner
and Manufacturer, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN APPARATUS TO BE EMPLOYED IN THE PREPARATION OF
COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
My Invention relates to such machinery used in the preparation of cotton
or fibrous materials as "drawing frames," and the Invention may be applied
to other machines wherein "slivers" of fibrous materials are delivered to and
contained in cans or receptacles, and to which stop motions are applied to
stop the delivery on the sliver becoming disunited.
The Invention being particularly applicable to the drawing frame I describe
it as used in such machine.

page_text: The improvements consist in the use of an arrangement of apparatus for
bringing the ordinary stop motion into action when the can is full, and the
apparatus consists of a pawl fixed on the ordinary rocking shaft, which pawl
gives an intermittent motion to a ratchet wheel mounted on a shaft, at the
end of which is a worm gearing into a worm wheel, and on the worm wheel
shaft a disc is fixed, having a projection on one part of its periphery; between
this disc and the usual "spoon levers" a lever extends, so that as the disc is
caused to rotate by the working shaft, pawl, and worm and worm wheel once
in each revolution, the projection strikes the lever which lifts the ordinary
"spoon lever" over which the "sliver" passes, and which brings the ordinary
stop motion into action as though the sliver had broken, and so stops the
delivery of more "sliver" to the can, whereby waste of sliver is prevented and
a regular weight of sliver is delivered to the can.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Hyde Barton in the Great Seal Patent Office on the
18th December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HYDE BARTON, of Chorley, in the County of Lancaster, Spinner and Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of June, 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
Robert Hyde Barton, Her special license that I, the said Robert Hyde
Barton, my executors, administrators, and assigns, or such others as I, the
said Robert Hyde Barton, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 IMPROVE-
MENTS IN APPARATUS TO BE EMPLOYED IN THE PREPARATION OF COTTON AND OTHER
FIBROUS MATERIALS," upon the condition (amongst others) that I, the said
Robert Hyde Barton, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in what

page_text: 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 Robert Hyde Barton, do hereby declare
the nature of the 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 Drawings (that is to say):
My Invention relates to such machinery used in the preparation of cotton
or fibrous material as "drawing frames," and the Invention may be applied
to other machines wherein "slivers" of fibrous materials are delivered to and
contained in cans or receptacles, and to which stop motions are applied to
stop the delivery on the sliver becoming disunited, or it may be applied to
carding engines for the same purpose.
The Invention being particularly applicable to the drawing frame I describe
it as used in such machines.
The improvements consist in the use of apparatus for bringing the ordinary
stop motion into action when the can is full, and this apparatus consists of a
pawl fixed on the ordinary rocking shaft, which pawl gives an intermittent
motion to a ratchet wheel mounted on a shaft, at the end of which is a worm
gearing into a worm wheel, and on this worm wheel shaft a finger is fixed
having a projection on one part of its periphery; between this finger and the
usual " spoon levers
a lever extends, so that as the finger is caused to rotate.
by the rocking shaft, pawl, and worm and worn wheel once in each revolution
the finger raises the lever, which lifts the ordinary "spoon lever" over which
the "sliver" passes, and which brings the ordinary stop motion into action as
though the sliver had broken, and so stops the delivery of more "sliver" to
the can, whereby waste of sliver is prevented, and a regular weight of sliver is
delivered to the can.
In order that the Invention may be better understood and explained in
detail I have hereunto attached a Sheet of Drawings made upon a scale of
about three inches to the foot, and having similar letters of reference marked
upon corresponding parts of the apparatus.
Fig. 1 represents the end view of a "drawing frame to which one
arrangement of apparatus is shewn applied, and as employed for actuating the
ordinary "stopping motion" of such frame, so as to arrest the delivery of
sliver from the rollers into the receiving can has become full, or has received
a certain quantity or weight of material; Fig. 2 represents a back view of the
same shewn in elevation, and Fig. 3 represents a similar arrangement of

page_text: apparatus applied to the front stand of carding engines which is employed for
giving an alarm at intervals of time corresponding to the time required for
filling the can receiving the "sliver" from the rollers.
In Figs. 1 and 2, a, a, is the framing of an ordinary "drawing frame;"
6 is the spoon or -stop guide over which the slivers of cotton pass before
being received by the drawing rollers; c,. the rocking shaft, and d the can
receiving the sliver of cotton after they have passed through the drawing
rollers, all being well-known parts of the "drawing frame." The improved
motion for stopping the delivery of the cotton when the can is full or a
certain required quantity or weight has been received therein consists of the
following arrangement of mechanism. The rocking shaft c is provided with a
slotted lever e, to which is secured an adjustable pawl f which actuates the
ratchet wheel g so as to cause such ratchet particularly to revolve with every
vibration of the rocking shaft; this revolving motion of the ratchet wheel 9 is
transmitted through the worm h and worm wheel i to the finger or "tappet" k
seen in Fig. 2. The said finger k makes one revolution in a greater or less
time by changing the ratchet wheel or worm wheel for fine or coarse
"counts," the ratchet and worm wheel being the same; and in its revolution
the finger is brought into contact with one end of the bell-crank lever m, and
the opposite end of such lever lifts the "spoon" or guide b, so as to catch the
bar of the rocking shaft, thereby stopping the frame, brings the ordinary stop
motion into action, so that according to the size of the worm wheel a greater
or less amount of time will pass during the revolution of the finger or tappet k,
thereby allowing any required amount or weight of cotton or material to be
delivered into the can d.
In Fig. 3 an arrangement of apparatus applied to the carding engine is
shewn, which is employed for giving notice or calling attention when the
can d is full; in this arrangement the worm and worm wheel are dispensed
with, the ratchet "pawl" and finger tappet only being used, the finger tappet
being caused to revolve slowly by the reciprocating action of the pawlf on the
ratchet wheel g, the said finger at each revolution coming into contact with
the finger o actuating the bell or other alarm p, thereby giving notice
that the can d is full, or has received a sufficient quantity or weight of
cotton.
I am aware that other arrangements of apparatus and gearing may be
designed to act upon the "spoon," and so upon the ordinary stop motion of
the machine, I do not therefore confine myself to the precise arrangement
herein shewu; but I claim,-

page_text: First, the novel use and application of a stop motion to act upon the
spoons" in "drawing frames," and through them to actuate the ordinary
stop motion.
Secondly, I claim the arrangement of mechanism for effecting such object.
And, thirdly, in the application of such mechanism to carding engines, as
herein-before described.
In witness whereof, I, the said Robert Hyde Barton, have hereunto set
my hand and seal, this Tenth day of December, in the year of our
Lord One thousand eight hundred and sixty-seven.
ROBERT HYDE BARTON. (L.S.)
