IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING COTTON AND OTHER FIRROUS SUBSTANCES
Year: 1852

page_text: LETTERS PATENT to John Roydes, of Greengate, near Rochdale,
in the County of Lancaster, Cotton Carder, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING
COTTON AND OTHER FIRROUS SUBSTANCES"
Scaled the 7th June 1853, and dated the 21st December 1852.
PROVISIONAL SPECIFICATION left by the said John Roydes at
the Office of the Commissioners of Patents, with his Petition,
on the 21st December 1852.
I, JOHN ROYDES, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING COTTON
AND OTHER FIBROUS SUBSTANCES" to be as follows:-
My Invention consists in a peculiar arrangement of apparatus ap-
plied to the drawing frame, for the purpose of arresting the motion
of the machine upon the breakage or deficiency of the sliver or web.
The fingers or triggers, which are kept balanced by the material
passing through the machine, are placed between the drawing and

page_text: delivering rollers, and they are capable of turning upon centres. The
arms of these fingers or triggers, however, are not a portion of, or
directly communicated to, the part which iminediately acts upon the
stopping motion, but are detached therefrom; and they are provided
with weights capable of being slidden nearer to or further from the
centre of motion, in order to effect an adjustment of the balance.
Upon a breakage taking place, the fingers or triggers turn upon
their centres, and cause their arms to arrive in contact with other
parts, by the shifting of the position of which the stopping of the
machine is effected in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said John Roydes in the Great Seal Patent
Office on the 21st June 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN ROYDES, of Greengate, near Rochdale, in the County of Lan-
caster, Cotton Carder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by
Her Letters Patent, bearing date the Twenty-first day of Decem-
ber, in the year of our Lord One thousand eight hundred and fifty-
two, in the sixteenth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said John Roydes,
Her special license that I, the said John Roydes, my executors, ad-
ministrators, and assigns, or such others as I, the said John Roydes,
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 for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR DRAWING COTTON AND
OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that
I, the said John Roydes, by an instrument in writing under my
hand and seal, should particularly describe and ascertain the nature

page_text: 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 John Roydes, do hereby de-
clare the nature of my said Invention, and in what manner the saine
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 consists in a peculiar arrangement of apparatus
applied to the "drawing frame," for the purpose of arresting the
motion thereof, upon a breakage of the sliver or web taking place,
or upon an undue quantity passing onward.
The trumpets or fingers, which are kept balanced by the material,
are placed between the drawing and delivering rollers, and are
capable of turning upon centres. The arms of these trumpets or
fingers, however, are not a portion of the part which immediately
acts upon the stopping motion, but are detached therefrom; and
they are provided with weights, capable of being slidden nearer to or
further from the centre of motion, in order to effect an adjustment of
the balance. In order that my Invention may be fully understood,
I will proceed to describe a Drawing accompanying this my Specificn-
tion, and which is a partial sectional view of a drawing frame, with
my improvement adapted. The ordinary drawing rollers are shewn
at a, from which the material, before arriving at the delivering
rollers b, passes through the trumpet or finger c, which is attached to
the upper portion of a bent lever d, mounted so as to be capable of
turning upon centres attached to the plate e.
The lever d, is pro-
vided with a weight f, which is situate above the boss g, of a lever
h. This lever turns upon a fixed centre at i, and is connected at its
other extremity to a vertical rod j, which after passing through the
plate k, supports the heavier end 1*, of a lever 1, 1*, turning upon a
centre at o, and provided with a hook m, situate over the usual vi-
brating barn. During the operation of the machine, the hook m, will
be kept clear of the vibrating arm, by the heavier end 1*, of its lever,

page_text: which also, through the intervention of the rod j, imparts to the lever
h, , a slight tendency to turn upon its centre so as to carry the boss g,
upward. This tendency is, however, counteracted by the nob f, the
action of which, apart from other influence, would be to descend by
turning the lever d, upon its centre. Such motion, however, is
counteracted by the tension of the web or sliver, passing through
the trumpet c, and the several parts are therefore held in equilibrium
in the position shewn in the Drawing; but suppose a deficiency of the
material, owing to a lapping of the rollers or other causes, to have
taken place, then the tension upon the trumpet will be reduced, and
the nob f, not being held up with the original force, the equilibrium
will be destroyed, and the consequent turning of the lever d, upon its
centre will cause a like motion of the lever h, which being transferred
by the rod j, the hook m, will be brought within range of the vi-
brating arm n, and the motion of the machine will be arrested as or-
dinarily practised. If more than the proper quantity of material
should be delivered by the rollers a, it will not be able to pass through
the trumpet c; and as the rollers a, continue to revolve, the web or
sliver between a, and b, will become slackened so as to reduce the
tension, and cause the stopping of the machine, as before described.
In order to regulate the force necessary to overcome the balance of
the several parts, and therefore to determine the variation of tension
in the material which shall bring the apparatus into effect, Iapply an
adjustable weight p, to the lever h, which weight is thus an in-
strument for establishing the equilibrium. By shifting it, therefore,
in reference to its centre of motion, the sensitiveness of the арра-
ratus may be regulated.
Having thus described and ascertained the nature of my said
Invention, and the nanner in which the same is to be performed,
I desire it to be understood that I claim, as secured to me, the
application to drawing franes of a stop motion between the drawing
and delivering rollers, so arranged that the trumpet finger, or other
such part, which is acted on by the sliver or web, is detached from the
other portions of the stopping apparatus, although acting in concert
therewith. Also I claim the application of a weight or weights, capable

page_text: of adjustinent, so as to regulate the sensitiveness of the stop
motion.
In witness whereof, I, the said John Roydes, have hereunto set
my hand and seal, this Twentieth day of June, in the year
of our Lord One thousand eight hundred and fifty-three.
