Dobson and Barlow, of Bolton, in the County of Lancaster, Machine
Maker, and Robert Tonge, of the samo Place, Forcman, for the
66
Invention of IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING.
PROVISIONAL SPECIFICATION left by the said Thomas Henry Rushton
and Robert Tonge at the Office of the Commissioners of Patents,
with their Petition, on the 21st August 1873.
We, THOMAS HENRY RUSHTON, of the Firm of Messieurs Dobson and
Barlow, of Bolton, in the County of Lancaster, 'Machine Maker,
and ROBERT TONGE, of the same Place, Foreman, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING
AND DOUBLING," to be as follows:-
Our Invention consists of an improved arrangement of mechanism for
, producing a uniformly tight nose in copping, also for keeping the cops
free from snarls and allowing the yarn to be wound nearer to the spindle
point, than heretofore.

page_text: In performing our Invention we fix to the carriage a bracket or frame
in which is a vertical slot or slide made to receive an arm upon which
is mounted a bowl; a screw passes through the whole length of the
vertical slot or slide, and also through the before mentioned arm, and
on the screw is a nut fitting into the said arm. The screw is turned
partly round at every stretch by a ratchet wheel, and catch mounted
upon a loose lever and fitted at the end of the said shaft; the lever comes
against a fixed stud when the carriage is out. The arm in the said slot
with the bowl are thus raised by self-acting mechanism in the said slot
or slide, and at every inward run of the carriage the bowl acts on the
winding chain, thereby causing the chain to deflect in an increasing ratio
and giving more winding at the nose of the cop; the said arm is raised
as the cop is built, and so varies the winding as the taper of the spindle
blade requires.
SPECIFICATION in pursuance of the conditions of the Letters Patent 1
filed by the said Thomas Henry Rushton and Robert Tonge in the
Great Seal Patent Office on the 20th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HENRY RUSHTON, of the Firm of Messieurs Dobson and Barlow, of
Bolton, in the County of Lancaster, Machine Maker, and ROBERT 2
TONGE, of the same Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of August, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
-seventh year of the reign, did, for Herself, Her heirs and successors, 2
give and grant unto us, the said Thomas Henry Rushton and Robert
Tonge, Her special licence that we, the said Thomas Henry Rushton
and Robert Tonge, our executors, administrators, and assigns, or such
others as we, the said Thomas Henry Rushton and Robert Tonge, our
executors, administrators, and assigns, should at any time agree with 3
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 "Im-

page_text: PROVEMENTS IN MACHINERY FOR Spinning and DOUBLING," upon the condition
(amongst others) that we, the said Thomas Henry Rushton and
Robert Tonge, 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 Thomas Henry Rushton and
Robert Tonge, 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 Invention consists of an improved arrangement of mechanism for
producing a uniformly tight nose in copping; also for keeping the cops
free from snarls and allowing the yarn to be wound nearer to the spindle
point than heretofore.
In performing our Invention we fix to the carriage a bracket or frame
in which is a vertical slot or slide made to receive an arm upon which is
O mounted a bowl; a screw passes through the whole length of the
vertical slot or slide, and also through the before mentioned arm, and on
the screw is a nut fitting into the said arm; the screw is turned partly
round at every stretch by a ratchet wheel and catch mounted upon a
loose lever and fitted at the end of the said shaft, the lever comes
5 against a fixed stud or bracket when the carriage is out. The arm in
the said slot with the bowl are thus raised by self-acting mechanism in
tho said slot or slide, and at every inward run of the carriage the bowl
acts under the winding chain, thereby causing the chain to deflect in an
increasing ratio, and giving more winding at the nose of the cop. The
O said arm is raised as the cop is built and so varies the winding as the
taper of the spindle blade requires.
And in order that our Invention may be fully understood and readily
carried into operation wo will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
5 thereon.

page_text: self-acting mule to which our improvements are applied; Fig. 2 is an
end view of the same.
The Invention consists of an improvement in that part of the mule
known as the winding motion. It is well known that as the chase of
the cop grows up the spindle towards the finish owing to the taper shape.
of the spindle blade the yarn is not wound sufficiently tight just at the
nose of the cop, and that the winding is here aided by nose pegs and
so called nosing motions which act upon the quadrant chain, and by
pressing the chain a little out of the right line give a little more
winding. All the motions now in use are more or less defective, either
through not being self acting or from other causes.
In Figs. 1 and 2 a is the carriage square, upon which is secured the.
bracket b, which is made to receive the slide or framo c; this slide or
frame is so arranged as to slide up or down in the bracket bas required,
and it is also made to allow a screw-cut shaft d to pass from top to
bottom, which shaft is supported at each end in bearings; at the upper
end of the screw-cut shaft is mounted a star or ratchet wheel d¹, and a
loose tumbler lever d³, which is provided with a catch to act upon the
teeth of the star or ratchet wheel d; at every outward run of the
carriage the loose tumbler lever d² comes in contact with a stud or
bracket e fixed on the headstock, thereby causing the catch to take up
one tooth or more teeth as required of the ratchet wheel d³, thus turning
the screw d and consequently raising the nuts on the inward run of the
carriage; the spring brings the tumbler lever d³ back in position to be
acted upon by the stud e. on the next outward run of the carriage. The :
nut f which fits upon the screw-cut shaft d is provided with a bowl ƒ³,
and as the nut f is raised in the slot the bowl f¹ is raised against the
quadrant chain and increases the winding or speed of the spindle in
proportion as the bowl acts upon the chain; the bowli is fixed upon the
bottom part of the slide or frame c, and this bowl runs up the incline j
just as the carriage completes the inward run and so raises the slide or
frame c, causing it to act a little more against the quadrant chain,
which gives a little more winding just at the cop nose, thus dispensing
with the long arm nose peg previously used and making a good firm cop
nose quite free from snarls.
At the commencement of building a set of cops the nut f is near the
lower end of the screw shaft d, and the quadrant chain & then.

page_text: straight line from the nut in the radial arm to the winding-on barrel, as
shewn by the lower dotted line in Fig. 1; but after the carriage has
performed a certain number of stretches, and the bottom of the cop has
been built, the nut f is gradually raised, thereby bringing the bowl f¹
against the under side of the quadrant chain h and producing the
desired deflection of the chain to increase the winding on, and the
amount of deflection of the chain is gradually increased until the set of
cops is completed, thereby forming a hard nose and preventing snarls.
Having thus stated the nature of our Invention, and described the
manner of performing the same, wo declare that we claim,-
-
First. The improved combination and arrangement of machinery for
winding the yarn on the spindles, as shewn and described, and the
application thereof or other equivalent machinery to the carriage
square.
Secondly. The bowl i and inclined plane ; for raising the slide c, as
shewn and described.
Thirdly. The machinery described, or any equivalent thereof, acting
on the under side of the quadrant chain.
And, lastly. The combination of the slide c with the screwed shaft d,
as shewn and described.
In witness whereof, I, the said Thomas Henry Rushton, for
myself and on behalf of the said Robert Tonge, have hereto set
my hand and seal, this Nineteenth day of February, One
thousand eight hundred and seventy-four.
