page_text: LETTERS PATENT to James Hall, of Glossop, in the County of Derby,
Mechanic, William Dunkerley, of Dukinfield, in the County of Chester,
Machinist, and Samuel Schofield, of, Ashton-under-Lyne, in the County
of Lancaster, Iron Founder, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES, AND FOR
DOUBLING YARNS."
Sealed the 18th April 1865, and dated the 26th October 1864.
PROVISIONAL SPECIFICATION left by the said James Hall, William
Dunkerley, and Samuel Schofield at the Office of the Commissioners
of Patents, with their Petition, on the 26th October 1864.
We, JAMES HALL, of Glossop, in the County of Derby, Mechanic, WILLIAM
DUNKERLEY, of Dukinfield, in the County of Chester, Machinist, and SAMUEL
SCHOFIELD, of Ashton-under-Lyne, in the County of Lancaster, Iron Founder,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES, AND FOR
DOUBLING YARNS," to be as follows:-
Our improvement in machinery for preparing cotton and other fibrous
substances is applicable to roving and intermediate frames, and it consists
in an improved combination of machinery for stopping the frame when an end
breaks.
In performing our Invention the ends or rovings for feeding the frame pass
in going to the drawing rollers through holes in a plate; to this plate double

page_text: levers are jointed, the lower ends of which are held by the rovings so as to
clear slots in the plate, and feelers fixed on a rocking cross shaft pass through
these slots as long as the rovings continue to be supplied to the drawing rollers;
as soon as an end breaks the lower end of the corresponding lever covers the
slot and the feeler is prevented from passing through the slot; the consequence
is that a catch which has a to-and-fro motion given to it by a crank remains
in position for acting on the knocking-off lever, which thus moves the driving
strap from the fast to the loose pulley. To the knocking-off lever is connected
a rod with projecting pins, which act on the double levers, and when the broken
end has been repaired, and the knocking-off lever is moved to bring the driving
strap on to the fast pulley, the pins on the rod are moved to one side and free
from the double levers. When an end breaks between the front drawing
roller and the bobbin, a lever, which had been held in position by the end
moves to one side, and thus brings the end of another lever over a slot in the
plate above referred to; this action again brings. the catch into. operation on
the knocking-off lever, as before described.
Our improvements in machinery for doubling yarns is applicable to the
ordinary throstle doubling. frame; and it consists also in an apparatus for
stopping the top roller when a yarn breaks.. To the. cap. bar or other con-
venient fixing is jointed a lever, one end of which is held by the yarn going
from the roller to the spindle,, the other end when the yarn breaks comes in
contact with a pin projecting from the top roller and stops it. The yarn passes
as usual around the top roller, but-in-the place where the yarn passes the roller
is reduced in diameter, so that when the roller is stopped there is no rubbing
on the yarn.

page_text: said James Hall, William Dunkerley, and Samuel Schofield, Her special?
license that we, the said James Hall, William Dunkerley, and Samuel.
Schofield, our executors, administrators, and assigns, or such others as we, the
said James Hall, William Dunkerley, and Samuel Schofield, 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 "IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND
OTHER FIBROUS SUBSTANCES, AND FOR DOUBLING YARNS," upon the condition
(amongst others) that we, the said James Hall, William Dunkerley, and
Samuel Schofield, our executors or administrators, by an instrument in writing
under our, or their, or one of our or their hands and seals, 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 we, the said James Hall, William Dunkerley, and
Samuel Schofield, 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 (that is to say) :-
Our improvement in machinery for preparing, cotton and other fibrous
substances is applicable to roving and intermediate frames, and it consists in an
improved combination of machinery for stopping the frame when an end
breaks.
Our improvement in machinery for doubling yarns is applicable to the
ordinary throstle doubling frames, and it consists also in an apparatus for
stopping the top roller when a yarn breaks.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describé the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
.
Figure 1 is an end elevation, and Figure 2 a-side elevation of part of a
roving frame to which our improvements are applied.
a, a, are the usual drawing rollers supported on stands 6, fixed to the roller
beam c.. The ends or rovings for feeding the frame pass, in going to the
drawing rollers a, through holes in a plate d; to this plate are jointed the double
levers e, e, the upper ends of which are held by the roving, so as to keep the
lower ends clear of the slots in the plate d. The feelers f, fixed on a rocking
cross shaft g, pass through these slots as long as the rovings continue to be

page_text: supplied to the drawing rollers, the rocking shaft being actuated by the
excentrich on the shaft i, to which is fixed a pinion driven by a pinion on one
of the drawing rollers; as soon as an end breaks the lower end of the
corresponding leve e covers the slot in the plate d, and the feeler f is prevented
from passing through the slot, the consequence is that the catch j, which has
a to-and-fro motion given to it by the crank k, and an up-and-down motion
imparted by the excentric h, acting on the lever g¹, fixed to the shaft g, remains
in position for acting on the knocking-off lever 1, which thus moves the driving
strap from the fast to the loose pulley. To the knocking-off lever is connected
the rod m, by an arm acting on an incline on the rod,-which is furnished
with projecting pins acting on the double levers e, and when the broken end
has been repaired and the knocking-off lever is moved to bring the driving strap
on to the fast pulley, the pins on the rod m are moved to one side and free
from the double levers e. When an end breaks between the front drawing
roller and the bobbin, the lever n, which had been held in position by the end,
moves to one side, and thus brings the end of the intermediate levers o over a
slot in the plate d; this action again brings the catch j into operation on the
knocking-off lever as before described; the levers.n and o,are both fixed on a
cross shaft n'. The connection between the knocking-off lever and the
driving strap is similar to that in roving frames of the ordinary construction,
and therefore does not require to be fully described.
Figure 3 is an end view, and Figure 4 a front view of part of an ordinary
tbrostle doubling frame to which our improvements are applied. p is the
bottom roller supported in the stands q, fixed to the roller beam r; s is the
top roller, supported as usual on the bottom roller and in slots in the cap bar
t. To the cap bar t or other convenient fixing is jointed the lever u, one end
of which is held up by the yarn going from the roller to the spindle, and the
other end when the yarn breaks comes in contact with a pin projecting from
the top rollers, and stops it; we have shewn three of these pins in the top
roller, but a greater or less number may be used. The yarn passes as usual
around the top rollers, but in the place where the yarn passes the roller is
reduced in diameter, as shewn in Figure 4, so that when the roller is stopped
there is no rubbing on the yarn.
This part of our Invention may be modified as shewn in Figures 5 and 6;
in these views the top roller s, instead of having a circular. recess all round is
provided with a flat groove which comes opposite the top roller p' when the
pin is caught by the lever u.
Having thus stated the nature of our, Invention, and described the manner
of performing the same, we declare that we claim,-

page_text: First, the improved combination and arrangement of parts applicable to
roving and intermediate frames for stopping the machine when an end breaks,
as shewn and described in reference to Figures 1 and 2.
And, secondly, the improved combination and arrangement of parts applicable
to throstle doubling frames for stopping the top roller when an end breaks
or when a single yarn passes, as shewn and described in reference to Figures
8, 4, 5, and 6.
In witness whereof, we, the said James Hall, William Dunkerley, and
Samuel Schofield, have hereto set our hands and seals, this Eighteenth
day of April, One thousand eight hundred and sixty-five.
JAMES HALL.
