PROVISIONAL SPECIFICATION left by the said John Thompson,
William Henry Rhodes, and John Wain at the Office of the Com-
· missioners of Patents, with their Petition, on the 26th December
1873.
We, JOHN THOMPSON, of the Firm of Messieurs Curtis, Sons, and
Company, of Manchester, in the County of Lancaster, Machine Maker,
and WILLIAM HENRY RHODES and JOHN WAIN, of the same Place,
Foremen, do hereby declare the nature of the said Invention for "In-

page_text: PROVEMENTS IN MACHINERY POR PREPARING, SPINNING, AND DOUBLING COTTON AND
OTHER FIBROUS SUBSTANCES," to be as follows:-
`. Our improvements in machinery for preparing cotton and other fibrous
substances relate to carding engines in which rollers and clearers are
used, and it consists in stripping the main cylinder by one or more of 1
the clearers or other rollers. To accomplish this we place a pulley on
the axle of one of the clearers or rollers, and this pulley is driven by a
pulley fixed to the loose pulley on the axle of the main cylinder or
otherwise.
When the driving strap is moved from the fast to the loose pulley the 1
main cylinder continues to revolve until its momentum is expended, and
during this time the clearer or roller driven by the pulley on the loose
pulley or otherwise gradually collects on its circumference the fly and
impurities that were on the main cylinder, which fly and impurities are
then removed by stopping the rotation of the clearer or other roller, and
then moving it to and fro by hand against its adjacent roller.

mangle wheel described in the said Patent, and employ a scroll and band
for moving the carriage. We place a cam shaft for effecting the various
changes in front of the machine, and this cam shaft is thrown in and out
of gear by a lever actuated by the carriage. The squaring shaft is
driven from the rim shaft by a train of wheels and pinions, and by a
band and pulleys, which band slips in case of accident so as to prevent
injury.. The taking-in and backing-off are both driven by a pulley and
band; the pulley is fixed to the loose pulley on the rim shaft. By this
means the requisite changes for coarser or finer yarn can be effected by
changing the diameter of one of the pulleys. The winding-on chain is
taken over a pulley, the axle of which is moved to and fro by means of a
cam acting on a lever or other equivalents. By this means we are
enabled to make cops of the required diameter without increasing the
length of the radial arm.
Another part of our Invention consists in fixing a pinion on the
drawing-out shaft of self-acting mules, which pinion gears into a short
rack connected to the carriage. By this means the outward run of the
carriage is commenced by positive gearing, whereas at present the motion
depends on the band,
O SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Thompson, William Henry Rhodes, and
John Wain in the Great Seal Patent Office on the 25th June
1874.

said John Thompson, William Henry Rhodes, and John Wain, our
executors, administrators, and assigns, or such others as we, the said
John Thompson, William Henry Rhodes, and John Wain, our executors,
administrators, and assigns, should at any time agree with and no t
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, SPINNING, AND DOUBLING COTTON AND OTHER FIBROUS 1
SUBSTANCES," upon the condition (amongst others) that we, the said John
Thompson, William Henry Rhodes, and John Wain, 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 1
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 Thompson, William Henry
Rhodes, and John Wain, do hereby declare the nature of our said 2
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 machinery for preparing cotton and other fibrous
substancos relato to those carding engines in which rollers and clearers 2
are used; and it consists in stripping the main cylinder by one or more
of the said clearers or other rollers.
Our improvements in machinery for spinning and doubling relate. to:
throstle frames, and it consists in an improved mode of keeping the oil
clean and guiding it back to the footstop.
Another part of our Invention consists in fixing a pinion on the
drawing-out shaft of self-acting mules, which pinion gears into a short
rack connected to the carriage. By this means the outward run of the
carriage is commenced by positive gearing, whereas at present the motion

Our improvements in machinery for spinning and doubling consist
also in a new combination and arrangement of the parts of the machine
for which Letters Patent were granted to Henry Bernoulli Barlow, on the
Twentieth day of March 1866, Number 815, a communication, whereby
5 the various working parts are brought into convenient positions for the.
attendants, and by which the motions of the machine are performed with
great accuracy.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the two accompanying
Sheets of Drawings, reference being had to the figures and letters marked
thereon.
-
On Sheet 1 Fig. 1 is an elevation, and Fig. 2 a side view of part of a
carding engine of the ordinary construction, to which our improvements
are applied. a is the main cylinder; b, the doffer; c, c, the workers;
and d, d, the clearers, which are all made as usual. To the loose pulley
on the axle of the main cylinder a is fixed the grooved pulley a², which
by a band drives the pulley e¹ fixed on the axle e, to which is also fixed
the pulley es, which drives by strap the pulley d' on the axle of one of
the clearers d.
When the driving strap is moved from the fast to the loose pulley the
main cylinder continues to revolve until its momentum is expended, and
during this time the clearer or roller driven by the pulley a¹ on the loose
pulley or otherwise gradually collects on its circumference the fly and
impurities that were on the main cylinder, which fly and impurities are
then removed by stopping the rotation of the clearer or other roller, and
then moving it to and fro by hand against its adjacent roller.
Two or more clearers or rollers may be connected by pulleys and
straps, as shown at d. -
The above stripping apparatus may be applied to carding engines
•

page_text: rail h, which is provided with a shell rail ¹ to cover the footsteps, and
to prevent the escape of the oil, as sometimes customary.
Now our improvement consists in applying to each spindle fa small
split bush or ferrule f' which fits in the shell rail ¹, and serves to keep
the oil clean and guide it back to the footstep g.
We are aware that i
entire bushes or ferrules have been used, which do not prevent the oil
escaping up the spindle, but by making them with a split the small
groove forming the split catches the oil and returns it to the foot-
stop.
Fig. 5 represents part of a self-acting mule to which our improvements:
are applied. i, i, are the drawing rollers; ;, the drawing-out shaft;
and k, the carriage, which parts aro made as usual; j¹ is a spur wheel or
pinion fixed on the shaft j, which wheel or pinion gears into the short
rack k³, connected to the carriage k by a bolt passing through a slot.
There is a spring between the rack and carriage to allow the rack to ]
yield in case the tops of the teeth of the wheel and rack should come in
contact. When the carriage is close to the roller beam the wheel, is
in gear with the rack k', and the outward run of the carriage is
consequently commenced by positive gearing, whereas at present the
motion of the carriage depends on the strap or band, which is liable to a
slip.
On Sheet 2 Fig. 6 is an end elevation, and Figs. 7 and 8 are sido views
of our new combination and arrangement of the parts of the machine
for which Letters Patent were granted to Henry Bernoulli Barlow
on the Twentieth March 1866, Number 815, a communication from
abroad. is the rim or driving shaft, on which are the usual rim, band,
pulley, and backing-off cones, and the driving and loose pulleys I", P.
To the latter is fixed the grooved pulley for driving the taking-in and
backing-off motions by means of the band passing over guide pulleys,
and around the pulley m on the short upright shaft m¹. n is the front &
drawing roller; o, the spindles; and o³, the faller shafts, which are mado
to approach and recede from each others by the pinions p on the squaring
shaft p¹ gearing into the racks q and, as described in the Specification
of Henry Bernoulli Barlow's Patent before referred to. The cam shaft s
for effecting the various changes is placed in front of the machine, and
it is thrown in and out of gear in the following manner;-The roller n

page_text: in rising acts upon the incline s¹ on the upper end of the levers', the
lower end of which is jointed to the levers, the end of which is connected
to the end of the lever s³, see Fig. 8. To this lever is suspended the
plate so, with two inclines of the usual construction for effecting the
5 changes. When the faller shaft o' rises it acts on the incline & fixed to
the elbow levert connected by a pin to the lever sª. As the cam shaft
revolves it imparts motion to the catch boxes for starting and stopping
the drawing rollers, and for performing the other changes in the ordinary
manner. The squaring shaft p¹ is driven from the rim shaft by the
O bevel pinion ♬ gearing into the wheel u on the shaft u³, on which is the
spur pinion u³ gearing into the wheel ³ fast to a grooved pulley, the
band of which drives the pulley u, and this pulley by means of the
pinions and wheels shewn in Fig. 6 drives, the squaring shaft p². In
case of any obstruction the band passing over the pulley * slips, thereby
5 preventing injury. The taking-in motion (or when the spindles and
drawing rollers are approaching each other) and the backing-off motion
are both performed by the band, which drives the pulley m before
referred to. To the lower end of the shaft m' is fixed a bevel pinion. m³
gearing into the wheel on the shaft ³, on which is the friction box v.
To this friction box is fixed a spur pinion for driving the scroll shaft v³,
as shewn in Fig. 7. The diameter of the pulley m can be changed for
coarser or finer yarn. The lever for moving the friction cone of the
friction box o³ and the fallers are worked in the ordinary manner. The
pulley with the pinion fixed to it revolve on a stud in the lever us, and
5 this lever u is moved to throw the said pinion in and out of gear by a
rod jointed to the lever s' actuated by the cam shaft 8, see Fig. 6. The
winding-on chain w is fixed as usual to the barrel ³ of the carriage r,
and after passing around the pulley w' it is secured to the nut of the
radial arm z. The pulley w' is fixed on a short shaft supported in a
O swing frame w³. The radial arm is suspended to the stud¹ on the
carriage r, and the lower end of the radial arm is guided by the pulley ³
and fixed guide ³, as described in the Patent of Henry Bernoulli Barlow
above referred to. The lower end of the carriage is connected by the
link to the vertical lever a fixed on the same shaft as the lover xª, in
5 which is a screw provided with a nut connected by the link to the
swing frame w³. The position of the nut on the screw of the lover a is
varied by the governor or by the handle y, which by bevel pinions gives
motion to the diagonal shaft y. This. shaft imparts by bevel pinions
