Sealed the 29th December 1874, and dated the 14th October 1874.
PROVISIONAL SPECIFICATION left by the said John Hutcheson and
Thomas Henry Rushton at the Office of the Commissioners of
Patents, with their Petition, on the 14th October 1874.
We, JOHN HUTCHESON, of Glasgow, in the County of Lanark, North
Britain, Cotton Spinner, and THOMAS HENRY RUSHTON, of Bolton, in
the County of Lancaster, Machine Maker, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING AND
DOUBLING,'
"to be as follows:- .
Our improvements in self-acting mules for spinning consists in the
application of an extra tappet or adjusting lever mounted upon the
copping faller shaft, and provided with bowls and studs for the governor

page_text: chain to pass around, and this chain lowers the governor lever into gear
with the governor motion; also in an improved apparatus for starting
the drawing rollers when the carriage has travelled a certain distance
from the roller beam.
This apparatus consists of an incline mounted upon the carriage,
which incline is placed under the roller gear lever, and prevents the
drawing rollers from starting until the incline is withdrawn by the
motion of the carriage.
Our improvements in twiners for doubling consist in dispensing with
the ordinary gripping apparatus and friction pegs, and in applying in
lieu thereof à pair of rollers similar to those now in use in throstle
doubling frames; these rollers revolve in bearings in front of the
ordinary trough, and the yarns after leaving the trough are taken under
a friction pad, then through guide wires in a traversing rail, then
between the rollers, and thence to the spindle on which the doubled yarn
is wound. By means of these rollers snarls are prevented, as the yarn is
kept stretched until wound up, and by imparting a slow. rotary motion.
to the rollers during the winding up the length of the stretch is increased
while the cops are kept slowly in motion, thereby preventing sudden
jerks and breakages.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Hutcheson and Thomas Henry Rushton in the
Great Seal Patent Office on the 10th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HUTCHESON, of Glasgow, in the County of Lanark, North Britain,
Cotten Spinner, and THOMAS HENRY RUSHTON, of Bolton, in the County
of Lancaster, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of October, in the year
of our Lord One thousand. eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Hutcheson and Thomas
Henry Rushton, Her special licence that we, the said John Hutcheson
and Thomas Henry Rushton, our executors, administrators, and assigns,

page_text: .
or such others as we, the said John Hutcheson and Thomas Henry
Rushton, 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 SPINNING AND DOUBLING," upon the
condition (amongst others) that we, the said John Hutcheson and Thomas
Henry Rushton, 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 Inven-
tion, 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 Hutcheson and Thomas
Henry Rushton, 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 improvements in self-acting mules for spinning consist in the
application of an extra tappet or adjusting lever mounted upon the
counterfaller shaft, and provided with bowls and studs for the governor
chain to pass around, and this chain lowers the governor lever into gear
with the governor motion; also in an improved apparatus for starting
the drawing rollers when the carriage has travelled a certain distance
from the roller beam.
This apparatus consists of an incline mounted upon the carriage, which
incline is placed under the roller gear lever, and prevents the drawing
rollers from starting until the incline is withdrawn by the motion of the
carriage.
Our improvements in twiners for doubling consist in dispensing with
the ordinary gripping apparatus and friction pegs, and in applying in
lieu thereof a pair of rollers similar to those now in use in throstle
doubling frames; these rollers revolve in bearings in front of the
ordinary trough, and the yarns after leaving the trough are taken under
a friction pad, then through guide wires in a traversing rail, then between

page_text: the rollers, and thence to the spindle on which the doubled yarn is
wound. By means of these rollers snarls are prevented, as the yarn is
kept stretched until wound up, and by imparting a slow rotary motion.
to the rollers during the winding up the length of the stretch is increased
while the cops are kept slowly in motion, thereby preventing sudden
jerks and breakages.
And in order that our Invention may be fully understood and readily.
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is a transverse section of part of a self-acting mule to which
In
our improvements are applied, and Fig. 2 a front view of the same.
these views a is the carriage; b, the carriage square, to which is jointed
the governor lever c; d is the governor chain; e, the copping faller
shaft and f, the counter faller shaft. All these parts are made as usual.
To the counter faller shaft is fixed the extra tappet or adjusting lever f³,
around which the governor chain d is carried; this chain forms the
connection between the copping faller and counter faller shafts, as usual.
When the yarn becomes too tight the counter faller wire is raised, thereby
moving the adjusting lever f' in the direction of the arrow in Fig. 1, and
lowering the long arm of the elbow governor lever c, and causing the
vertical arm of the same to bind the governor cord, thereby letting. off
the requisite amount of winding on chain for reducing the tension of the
yarn.
-
Figs. 3 and 4 represent two. views of part of a self-acting mule, to
which our improved apparatus for starting the drawing rollers when the
carriage has travelled a short distance from the roller beam is applied.
h is the ordinary clutch box, one-half of which is cast with the mitre
wheel ¹ driven by the wheel on the coupling shaft, and the other half
is fixed to the spur wheel h³, which communicates motion to the drawing
rollers, as usual; i is an incline mounted on the carriage square b; and
is the roller gear elbow lever, the horizontal arm of which rests on the
incline and in the vertical arm is a key taking into a groove in the
boss of the spur wheel ², as usual. The vertical arm of the elbow
lever jis drawn in the direction of the arrow in Fig. 4 by the spring /
connected to the bracket. fixed to the framing of the headstock, as
usual. When the carriage in going out has withdrawn the incline i

page_text: clutch box into gear to start the drawing rollers. The object of this
arrangement is to prevent the drawing rollers from starting before the
carriage has commenced its outward run, and it is particularly beneficial
when the drawing rollers are stationary during the outward run of the
carriage.
Fig. 5 represents in section part of a twiner doubling machine con-
structed according to our improvements. a is the carriage, and m the
standard supporting the trough n, which we prefer to make of cast iron
lined with enamel, but which may be of wood or other suitable material;
o is the stand supporting five or other convenient number of bobbins p.
Two or more yarns are wound on each bobbin, according to the number
required to be doubled together, or in some cases the yarn may be drawn
off cops. The bobbins p are mounted on horizontal skewers, as shewn,
or on vertical skewers, according to the drag required. The yarns from
all the bobbins are passed under the guide wires q, q, to immerse them
in the liquid in the trough; they are then carried over the friction pad r,
then through the guides s in the traversing rail, and then between the
rollers t and u, which revolve in bearings fixed to the inside of the
trough n, so that any moisture that is expelled from the yarn may drop
again into the trough. The rollers t and u are made by preference of
iron coated with a deposit of copper to prevent rust, but they may be
covered with sheet brass, as in throstle doubling frames. After the
doubled yarns have passed between the rollers t and u they are taken
through the polishing clip v, and wound on the spindle w. By means
of these rollers snarls are avoided, as the doubled yarn is kept in the
proper state of tension until it is wound on the spindle, and by imparting
a slow rotary motion to the rollers during the winding up the length of
the stretch is increased, while the supply bobbins or cops are kept slowly
revolving, thereby preventing sudden jerks and breakages.
Having thus stated the nature of our Invention, and described the
manner of performing the same, we wish it to be understood that we do
not intend to limit ourselves to the details given, and that we claim,-
First. The application of an extra tappet or adjusting lever to the
counterfaller shaft of self-acting mules for governing the winding on, as
wow and desoxibod

page_text: Secondly. The application of an incline acting on the roller gear lever
of self-acting mules to prevent the drawing rollers starting before the
carriage begins its outward run, as shewn and described.
Thirdly. The general arrangement of the parts forming a twiner
doubling machine, as shewn and described.
And, lastly. Dispensing with the ordinary gripping apparatus em-
ployed in twiners for doubling, and the application of a pair of rollers in
lieu thereof.
In witness whereof, we, the said John Hutcheson and Thomas
Henry Rushton, have hereto set our hands and seals, this
Seventh day of April One thousand eight hundred and seventy-
five.
