IMPROVEMENTS IN MACHINERY FOR PREPARING, DRAWING, AND FINISHING WOOL, COTTON, AND OTHER FIBRES
Year: 1869

page_text: LETTERS PATENT to John Wilson, James Wilson, the younger,
Worsted Spinners and Manufacturers, and George Cryer, Mechanic,
all of Cross Hills, in the Parish of Kildwick, in the County of York,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR PREPARING,
DRAWING, AND FINISHING WOOL, COTTON, AND OTHER FIBRES."
Sealed the 13th July 1869, and dated the 26th January 1869.
PROVISIONAL SPECIFICATION left by the said John Wilson, James
Wilson, and George Cryer at the Office of the Commissioners of
Patents, with their Petition, on the 26th January 1869.
We, JOHN WILSON, JAMES WILSON, the younger, Worsted Spinners
and Manufacturers, and GEORGE CRYER, Mechanic, all of Cross Hills,
in the Parish of Kildwick, in the County of York, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR PRE-

page_text: PARING, DRAWING, AND FINISHING WOOL, COTTON, AND OTHER FIBRES," to be as
follows:-
The object of this Invention is by self-acting apparatus to stop such
machinery the moment waste commences to take place by reason of the
sliver or roving not passing direct from the rollers to the bobbins, which
I effect as follows:-On a bar or rod nearly the length of the frame and
parallel with the rollers are a number of lever catches, one opposite each
set of rollers; the lever catches work on a pin or stud about midway
their length, and the bar or rod carrying them has a traversing "to-
and-fro" motion imparted by means of an eccentric and wheel and a
weight; the sliver or roving in its passage from the rollers to the bobbin
bears on one end of the catch levers, the weight or tensional strain
keeping the catch levers down on their bar or rod. When waste takes
place the sliver or roving becomes slack, and the strain or weight being
removed allows the lever to "tilt" or work on its pin or stud, the other
end dropping into a notch in a second or lower bar, which is by the top
rod and catch drawn along its end, coming in contact with a spring and
lever on the end frame and stops the-machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Wilson, James Wilson, and George Cryer
in the Great Seal Patent Office on the 24th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WILSON, JAMES WILSON, the younger, Worsted Spinners and Manu-
facturers, and GEORGE CRYER, Mechanic, all of Cross Hills, in the
Parish of Kildwick, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of January, in the
year of our Lord One thousand eight hundred and sixty-nine, in
the thirty-second year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said John Wilson, James
Wilson, the younger, and George Cryer, Her special licence that we,
the said John Wilson, James Wilson, the younger, and
Cryer,
our executors, administrators, and assigns, or such others as we, the
said John Wilson, James Wilson, the younger, and George Cryer,

page_text: T.
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, DRAWING, AND FINISHING WOOL,
COTTON, AND OTHER FIARES," upon the condition (amongst others) that
we, the said John Wilson, James Wilson, the younger, and George
Cryer, our executors or administrators, by an instrument in writing
under our, or their, or one of their hands and seals, should par-
ticularly 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 John Wilson, James Wilson,
the younger, and George Cryer, 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:
The object of this Invention is by self-acting apparatus to stop such.
machinery the moment waste commences to take place by reason of the
sliver or roving not passing direct from the rollers to the bobbins, which
I effect as follows:-On a hollow bar or casing nearly the length of the
frame and parallel with the rollers are a number of lever catches, one
opposite each set of rollers; the lever catches work on a pin or stud about
midway their length, and the bar or rod carrying them has an internal
rod traversing "to-and-fro," motion being imparted by means of a cam
or an eccentric and wheel and a weight; the sliver or roving in its
passage from the rollers to the bobbin bears on one end of the catch
levers, the weight or tensional strain keeping the catch levers down on
their bar or rod. When waste takes place the sliver or roving becomes
slack, and the strain. or weight being removed allows the lever to "tilt"
or work on its pin or stud, the other end dropping into a notch in the
second or internal bar, which is by the top rod and catch drawn along,
its end coming in contact with the spring handle and lever on the end
frame and stops the machine.

page_text: Such being the nature and object of this our said Invention, we will
now proceed to fully describe the same, and in order that the same may
be clearly understood we have hereunto annexed a Sheet of Drawings,
and have marked the same with figures and letters of reference, the
same letter referring to the same part in the various views or Figures.
At Figure 1 is shewn elevation of part of a drawing box or frame with
our improvements attached. At A is shewn a hollow bar or casing
resting on the top spindle rail B supported on the said bar or casing,
and working on studs Care lever catches D. Inside the bar or casing A
is a rod E, to which a "to-and-fro" or traversing motion is imparted by
means of the cam F, which is on and receives motion from the bottom
roller shaft G and the pin F¹. So long as the wool or other fibres passes
from the rollers H, H', properly to the flyer and bobbin J, J', the tension
strain of the fibre on the arm of the lever catches D holds the other
arm or portion d of such levers clear of the notches K, K, in the tra-
versing rod E and the work proceeds. When the bobbin J' is full or is
not drawing properly, if one of the spindle bands break, if a knot gets into
the spindle top or a "mullock" (as shewn at L) occurs from any cause,
the strain being removed from the arm of the lever catch D, allowing the
same to "tilt" or work on its stud C, its other end falling into and
engaging the notch K in the bar E, as shewn at M, the cam will, by
means of the pin F" and the bar E to which such pin is attached, draw
or move the hollow bar or casing A, to which by means of the link N
the lever P is attached, moving this lever on its pin or stud R, the lower
end of the said lever bearing on the stop handle S, disengages the same,
and the strap is thereby removed from the fast to the loose pully and
the machine brought to a stand, preventing further waste. At Figure 2
is shewn cross section of shaft G, cam F, casing A, traversing rod E,
and link N. Figures 3 and 4 are detail views of these parts. Or an
eccentric may be employed for moving the traverse bar E, and a lever
and weight for returning the same; but we prefer the plan shewn in the
Drawings and herein fully described,
Having thus fully described and ascertained the nature and par-
ticulars of this our said Invention, together with the manner in which
the same is to be or may be performed, we would have it distinctly
understood that we claim as our Invention, the construction and arrange-
ment of the apparatus as and for the purpose herein fully described and

page_text: illustrated, or any mere modification of the same acting in substantially
the same or in a similar manner.
In witness whereof, we, the said John Wilson, James Wilson, the
younger, and George Cryer, have hereunto set our hands and
seals, this Twenty-third day of July, in the year of our Lord One
thousand eight hundred and sixty-nine,
