Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HILL, of Staleybridge, in the County of Chester, Cotton Spinner, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Nineteenth day of June, in
the tenth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said James Hill, my exors, adñors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said
James Hill, my exors, admors, and assigns, or such others as I, the said James
Hill, my exors, admors, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein
mentioned, should and lawfully might make, use, exercise, and vend, within
that part of Her Majesty's United Kingdom of Great Britain and Ireland.
called England, Her Dominion of Wales, and Town of Berwick-upon-
Tweed, in Her Islands of Jersey, Guernsey, Alderney, Sark, and Man, and
also in Her Majesty's Colonies and Plantations abroad, my Invention of
"IMPROVEMENTS IN OR APPLICABLE TO CERTAIN MACHINES FOR PREPARING, SPINNING,
AND DOUBLING, COTTON, WOOL, AND OTHER FIBROUS SUBSTANCES;" in which said
Letters Patent is contained a proviso, that if I, the said James Hill, should
not particularly describe and ascertain the nature of my said Invention, and
in what manuer the same is to be performed, by an instrument in writing,
under my
hand and seal, and cause the same to be inrolled in Her Majesty's.
High Court of Chancery within six calendar months next and immediately

page_text: after the date of the said Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, should utterly
cease, determine and become void, as in and by the same Letters Patent,
relation being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Hill, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following statement and description, reference being
had to the Drawings on two Sheets hereunto annexed. The several Figures
are drawn to the scales marked upon the Drawings, and when the same letters
and figures of reference occur in several views of the same machine, they
denote similar parts in each.
The nature of my said Invention consists,―
First, in combining and in working together in the same machine for the
first time the differential motion and the friction disc motion, and in com-
bining with the latter motion a scroll to alter, as required, the position of the
friction roller on the friction dise, whereby the varying speeds required can be
given in the winding-on process in such machines as coiling frames, slubbing
and roving frames, which wind slivers or rovings of cotton or other fibrous
substances upon discs, spools, or bobbins; also for the application and adapta-
tion of the above described motions to carding engines and drawing frames
for the purpose of coiling slivers in a compressed state into cans or other
receptacles.
Secondly, in the new combination of parts forming apparatus for placing
the rovings in uniform coils between plates, and in giving the required
pressure to the coils.
And, lastly, in the application of the said new combination of machinery,
consisting of differential wheels, friction disc, and scroll, to self-acting mules
and 'throstle frames, and to other machines of the like nature, for the purpose
of regulating the direction, tention, and speed in and at which the yarn shall
be wound on the spindles to 'form the cops in the mule and on the bobbins in
the throstles 'frames.
DESCRIPTION OF THE DOING

page_text: of displaying the working parts of the machine. Figure 3 is a plan view

Figure 8*, plan view and elevation of the top.coiling plate-17.
In Sheet 2, Figure 9 represents the end elevation of a bobbin frame, con-
structed on Mr. Higgin's principle, to which my improvements for winding
the rovings on to bobbins with conical ends are attached. Figure 10. is an
elevation of the same machine taken from the back, so that the working
parts of the machine may not be hid by the bobbins. Figure 11 is a section
taken through the line C, D, on Figure 10. Figure 12 is a front elevation
of my improvements, attached to the carriage of a self-acting mule constructed
on Mr. Roberts's principle. Figure. 13 is a side elevation of my
said
improvements in mules, with the frame of a headstock and part of a carriage,
to shew the application of my improvements; and Figure 14' represents a
front elevation of the scroll and apparatus connected therewith..
In Figures 1, 2, 3, and 4, representing the coiling frame, a is the driving
shaft; 6 and 6' are the fast and loose pulleys, which are driven round by a
strap from any convenient part of the mill gearing. c is a pinion shaft keyed
on the shaft a, and. taking. into a wheel d.keyed on the shaft e, upon which is
also keyed the bevel wheel f, driving the bevel pinion g keyed on the upright
shaft h. The leather friction roller i is turned round by the shaft h and slides
up and down it-on a groove and key. The shaft j is driven round by the
friction of the roller i against the disc l, and it revolves with a varying speed,
according to the distance the roller i is from the centre of the shaft j. The
difference between the fastest and slowest speeds of the shaftj must correspond
with the difference between the largest and smallest diameters of the coils
wound between the coiling plates w and 17. The disc is made to slide
freely upon a groove and key, and it is pushed against the friction roller i
by a-spiral spring m, which acts upon the boss of the disc. Near to the
other end of the shaft.j is keyed a pinion n, which gears into a wheel o keyed
upon a small shaft working in the bush. ·P; and the pinion g is also keyed on
the same small shaft, and-gears into the differential wheel r. Upon the shaft
eis keyed the mitre wheel s, which gears into two other mitre wheels t, and

page_text: through them imparts motion to the mitre wheel u; this motion is either
retarded or accelerated by the pinion q and differential wheel r, the velocity of
both of these being regulated by the varying speeds of the shaft j. The two
mitre wheels t gear into the fourth. mitre wheel u, which works loose on the
shaft e, and whose speed is regulated by the differential and disc motions
before described. The spur pinion vis fast on the boss of the mitre wheel u,
and imparts a varying velocity to the lower plate w, on which, the coils are
wound by means of the pinion gearing into the wheel x, the pinion y, fixed
on; the boss of the wheel, a, the carrier wheel z, driven round by the pinion y
and taking into the pinion 1 keyed upon the skew wheel shaft 2, which works
in bearings attached to the front rail 3 of the machine. The skew wheels 4
are. keyed on the shaft 2, and work into the pinions 5 fixed at the lower
end.of tubes 6, to which the bottom plates w are attached. The spindles 7
are driven at a regular and uniform speed by the spur pinion 8, also keyed
on the shaft e, and which gears into a wheel 9 revolving on the same
stud as the wheels y and x. The pinion 10 is fixed to the wheel 9, and
gears into the carrier wheel 11, which drives the carrier 12, and this
carrier gears into the pinion 13 (seen by a dotted line in Figure 1), keyed
on the bottom shaft 14, on which are also keyed the bevel wheels 15, gearing
into the bevel pinions 16, keyed on the spindles 7. The tubes 6 and bottom
plates ware loose upon the spindles 7, but the top plates marked 17 are fixed
on the top of the spindles by means of a pin fixed in the boss of the top
plate 17, taking into a groove turned in the spindle, as seen in the fourth
spindle in Figure 2, where the plates w and 17 are removed for shewing the
construction of the tube 6 and spindle 7. The friction roller i is lifted up; the
shaft h, by means of the scroll 18, keyed on the upright shaft 19, and which
acts on a small roller 20, revolving on a stud fixed in the double bush 21.
The shaft 19 receives its motion from the bottom shaft 14 by means of a
worm 22, fixed at the end of the shaft 14, and taking into gear with the
pinion 23, keyed on the inclined shaft 24, to which it gives a slow motion.
At the upper end of the shaft 24 is a bevel pinion 25, which drives the bevel
wheel 26, keyed on the end of the shaft 27, at the other extremity of which is
a mitre pinion 28, gearing into a similar mitre pinion on the shaft 19, and
thereby causing the scroll 18 to perform one revolution for every two layers of
rovings that are wound between the coiling plates w and 17. The top coiling
plate 17 is provided with a slot which extends from its circumference to near
the centre. In this slot the projection 29 of the rack 80 (see Figure 6) enters,
and through it is made the trumpet mouth for guiding the roving as it comes
from the hole through the upper part of the boss of the top plate 17 to its

page_text: position between the coiling plates. The rack 30 slides in a groove made
through the boss of the top coiling plate 17, and it is made to traverse from one
side of the plate to the other, so that the trumpet mouth in the projection 29 will
deposit the roving from the circumference of the coil to the inner diameter of
the same.
The traversing motion is given to the rack 30 by means of the
heart 31 (seen detached at Figure 8), which is keyed on the shaft 27, and by
the following pieces; the heart 31 acts upon a wedge-shaped piece of steel
32, which is fixed to the lever 33. The fulcrum of this lever is a stud 34,
fixed in the frame end, and as the heart revolves it raises the lever 33 into the
position shewn in Figure 4, and it is brought down again by the weight 35
hung to the end of the said lever. The link 36 is attached to the lever 33,
and connects it with the short lever 37 fixed on the segment shaft 38. The
small segments 39 are loose upon the shaft 38, but are connected with it by
the grooves cut in their bosses, taking into catches projecting from the bosses 40,
which are keyed on the shaft 38. Upon the upper end of the boss of the top
coiling plates 17 are placed the circular racks 41 (seen detached at Figure 7),
and the teeth of the segments 39 take into the grooves between the teeth of
the circular racks 41. The segments 39 have a slight upward and downward
motion given to them by the heart 31, thereby raising and lowering the
circular racks 41, which move freely on the boss of the top coiling plates.>
The small racks 42, attached to the circular racks 41, take into the small
segments 43 (see Figure 5), which hinge upon pins passing through the boss
of the plate 17, and as the larger segments 44, taking into the racks 80, are.
of the same piece as the small segments 43; the upward.and downward
motion given to the circular rack 41 is changed into a horizontal traversing
motion given to the rack 30, and by it to the trumpet mouth which conducts
the roving between the coiling plates, as already explained. The shape of
the heart 31 is so calculated that the rack 30 will be traversed across
the plate 17 at the requisite speed for depositing the rovings side by side, so
as to form a regular coil between the coiling plates 17 and w, and the coils. of:
rovings are pressed between the said plates by the action of the spring 45
against the under side of the plate w, the lower end of which spring bears.
upon a loose collar 46. The pinion 47 on the shaft e gives motion to the
front drawing roller by the train of wheels seen in Figures 1 and 2.
.
Having now described the various parts of which my improvements consist,
I will proceed to explain the manner in which they operate. The friction:
roller i and heart 31, with the various pieces connected with them, are shown.
in the positions they will assume when the roving is being wound on the
largest diameter of the coil, and when the friction roller and heart 31 have

page_text: performed the half of another revolution, the roller 20.will be at the lowest
part of the scroll 18. The friction' roller i will be working the disc at its
smallest diameter, and the roving will be delivered at the point near the
circumference of the tube 6, as seen in the first spindle of the frame where the
coiling plates are shewn close together, being the position they will occupy on
all the spindles when the frame begins to work or when the full coils have
been removed, and the operation of forming other coils commences. It will
be seen on referring to the fourth spindle of the frame that the tube 6 is made
with two circular grooves, and one groove in the direction of its axis. The
washers 46 slide freely on the tubes 6, and they have small pins taking into the
above-mentioned grooves; these washers serve as supports to the springs 45,
and when the coiling plates are near to each other. The pin of the washer 46
is placed in the upper circular groove, as seen in the first spindle of the frame;
but when the coil is about half completed, as seen in the second spindle, the
pin of the washer 46 has to be put into the lower of the circular grooves so as
to lower the bearing point of the spring 45, and thereby diminish its upward
pressure against the coiling plate w, which would become too great if the
washer were left in the upper groove. When the coils are about three fourths
completed the washers 46 are removed from their positions over the lower
circular grooves, and are let down until they bear on the boss of the skew
pinions 5, in which position they remain until the coil is complete. It will
be understood from the above description that the top coiling plates 17
revolve at a uniform speed in order in twist the rovings or yarn uniformly,
and that they remain at the same level; but the bottom coiling plates w
revolve at a varying speed to compensate for the different diameters in
the layers forming the coil, and that they slide down the tube 6 in
proportion as the rovings or yarn accumulate between the plates, the
bosses of the plates w being also provided with pins which enter into
the vertical groove of the tubes 6. As soon as there are a sufficient
number of layers between the plates 17 and w the machine is stopped, and the
coiling plates w must then be pushed down until the pin in the boss of the
said plates comes into the upper circular groove of the tubes 6, as seen in the
third spindle on the Drawing. The coils are now ready to be removed, and the
attendant has to slide the segments 9 out of geer with the circular racks 41,
and then to take off the top plates 17 by turning them so much round that the
pin, which was in the circular groove at the top of the spindles 7, comes oppo-
site the vertical groove of the same, thereby allowing the plate 17 to be lifted
away. When the plates 17 are removed, the coils of rovings are lifted from the
bottom plates, and put into cans or on to pegs, ready to be taken to the

page_text: succeeding machines. The various parts are then brought into the position
shewn on the first spindle of the frame, and the machine is ready for recom-
mencing its operation. The bottom plates ware covered with flannel to give
them the necessary adhesion to the rovings for forming the first layer. The
frame ends, and the various bearings of the shafts and wheels herein-before
described are clearly shewn in the Drawing, and do not require to be par-
ticularly referred to; the drawing rollers, roller beam, and stopping rod, are
similar to those generally used, and are well understood by persons conversant
with this class of machinery. In the above described machine the rovings
retain a real twist when wound between the plates 17 and w, similar to the
rovings formed on the bobbin of a slubbing frame, but, when artificial twist
only is given to the rovings in a similar way to that produced by the machine
known as Dyer's Tube Frame, then the top plate 17 may be stationary instead
of revolving, and a revolving trumpet mouth would have to traverse along the
slot of the top plate, so as to deliver the rovings on to the coil. In this case
the tubes 6 may be dispensed with, and the spindle and the rovings will revolve
at a speed corresponding to the delivery of the rollers: .. *
I will now proceed to describe my improvements in the slubbing and roving
frames drawn in Figures 9, 10, and 11, of the second Sheet of Drawings. "a repre-
sents the driving shaft of the slubbing frame, provided in the usual way with a fast
and loose pulley, as seen in Figure 11; and b is a mitre wheel fast on the shaft a,
forming part of the differential motion. c is the differential wheel loose on the
shaft a, and communicating the varying speeds of the disc d to the mitre wheel e
and spur wheelf, both of which are fast together, but loose on the shaft a.
The spur pinion q is keyed on the end of the shaft a, and gives motion to the
front drawing roller by means of the carrier h, which drives the pinion i on the
shaft j, and the wheel also fast on the shaft j, taking into the wheel 1 fixed on
the end of the front drawing roller. The wheel m, fixed on the shaft j, gives
the rotary motion to the friction 'roller n, by driving the pinion o fixed on the
shaft p, upon which is also fixed the mitre wheel q, taking into a similar wheel
on the upright shaft r, upon which the friction roller n slides up and down in
a similar manner to that described with reference to the coiling frame. In
this instance the scrolls on the shaft t, which causes the friction roller n to
move on the shaft, and thereby to give a varying speed to the friction disc d,.
is made to revolve slowly on its axis by means of the skew pinion' u fixed on
the driving shaft a.' The skew wheel w imparts au intermittent motion to the
upright shaft' on which it is fixed, by having, in two opposite places, its teeth
or cogs removed, so that when the pinion w is over one of the places without
teeth it can revolve without giving motion to the shaft a. The teeth of the

page_text: :
wheel w are brought into gear with those of the pinion u every time that the
rack pinion shaft v, see Figure 9, which moves the lifter, reverses its motion
by means of the spring y and eccentric box s, according to the plan shewn in
the Drawing, and which is generally known to persons conversant with this
class of machines. Near to the bottom of the upright shaft is fixed a worm 1,
which gears into a carrier 2, and this carrier drives the pinion 3 fast on the end
of the shaft 4, at the other extremity of which is fixed a bevil pinion 5, geer-
ing into the bevel wheel 6, keyed on the same upright shaft as the scrolls,
which thereby moves through a small fraction of a revolution every time that
the upright shaft x makes half a revolution. The friction disc d slides freely
on the end of the shaft 7, and is made to revolve with it by a groove and key;
the disc is held in contact with the friction roller n by the weighted elbow
-lever 8, the shorter arm of which is forked, and rests against pins projecting
from a boss 9 loose on the shaft 7, and pressing against the boss of the disc d.
Near to the other end of this shaft is keyed the pinion 10, which gears into a
'carrier 11, and this carrier drives the pinion 12 fixed on a short shaft 13, at
the other extremity of which is fixed the pinion 14, gearing into the differential
wheel c, thereby imparting to. it the varying velocities of the friction disc d.
Upon the short shaft 13 is also fixed a small bevel pinion 15, gearing into the
bevil wheel 16 fixed on the inclined shaft 17, and on the lower end of this s
shaft is keyed a bevil pinion 18, by the agency of which, and of the wheels 19
and 20, the rack pinion shaft is made to revolve first in one direction and
then in the other. The bevel wheel 20 is now shown in gear with the
pinion 18, but, as soon as the upright shaft has performed another half
revolution, the eccentric in the box z will be turned in the contrary direction, a
and the fork 21, which takes hold of the eccentric, will have drawn the
rod 22, and with it the bevel wheels 19 and 20, so far in the direction of the
arrow that the bevel wheel 19 will be in gear with the pinion 18, and thereby
reverse the motion of the shaft 23, and with it the motion of the lifter. The
bevil wheels slide on the shaft 23, by means of a groove and key, in the ordi- g
nary manner; and the pinion 24, at the end of the shaft 23, drives the
wheel 25 at the end of the rack pinion shaft v, as seen in Figure 9. The
spindles and flyers revolve at a uniform speed by means of a bevil wheel 26
keyed on the shaft a, and shewn by a dotted line in Figure 11, which-drives
the bevil pinion 27 fixed on the inclined shaft 28, at the lower extremity of 8
which is keyed the mitre wheel 29 gearing into a similar wheel on the shaft 30;
this shaft, and the shaft 31, are provided with the bevel wheels 32 gearing
into the bevel pinions on the spindles. The skew wheel shaft 33 receives a
varying velocity from the combined action of the friction disc d and differential

page_text: "wheel c in the following manner :-The spur, wheel of drives the .carrier 34,
which revolves upon a stud 86, fixed in a swing frame 35, suspended from the
driving shaft a. The flat bar 37 has a boss at each end, one of which fits on
the stud 36, and the other on the skew wheel shaft 33. The carrier 34 drives
another carrier 38, revolving on a stud in the bar 87, and this gears into the '
pinion 39 keyed on the skew wheel shaft 33; consequently, as the bobbins
and skew wheel shafts move up and down, the carriers 34 and 38 remain in
gear with the pinions f and 39, and continue to impart a varying rotary motion
to the bobbins or spools on which the rovings are wound. The, ends of the.
bobbins are tapered in the usual manner by the screws and expanding slides
contained in the box 40. When this machine is set to.work, the friction roller
n is about in the position shewn in the Drawing, that is to say, the friction
disc d is revolving at its greatest velocity to suit the speed required for winding
the rovings or slubbings on to the empty bobbins, and the scroll s raises the
friction roller n at every alternate movement of the lifter, until it works at the
largest radius of the disc d, at which time the bobbins are filled with rovings,
and the machine must be stopped so that the full bobbins may be taken away
and empty ones put in their places on the spindles. The scrolls is then turned
back to lower the friction roller into its proper position with respect to the
friction disc, and the machine may be started again as before. The bearings
for the various parts of this machine, the frame ends, the drawing rollers, and
the stopping rod are seen partially on the Drawings, but they do not require
to be particularly described, as they are well understood by persons acquainted
with machinery for preparing cotton.
I will now proceed to explain the application of my improvements to
spinning machinery, which improvements are described with reference to
Figures 12, 13, and 14, in which a represents the friction roller, and 6 the
upright shaft on which it works. This shaft revolves in bearings attached to
the travelling carriage of a self-acting mule. C is 'the friction' disc, covered in
this instance with strong leather; and d are two side plates for supporting the
bearings of the shafts, as seen best in. Figure 12. The lever e extends the
whole length of the going out of the carriage, and it is bent up at one end So..
as to receive a roller e*, which bears upon the inclined surface of the scroll f.
The other end of the lever hinges upon a stud working in, a bracket g fast.on
the floor of the room. The edge of the lever e fits into a groove in the boss of
the roller a, by which the roller a is moved up and down along the face, of the
disc c, according to the inclination of the lever e.
The scroll
is keyed on an
driven. by the.
upright shaft g, at the upper end of which is a worm wheel
worm i, keyed on the short shaft j, which works in two bearings fixed to the

page_text: standard k, and a third bearing fixed to the frame side of the headstock, as
seen.in Figure 14: The wheel is keyed on a shaft: at: the extremity of the
mule, headstock, and it works into the pinion m loose on the shaft j: The
back of the pinion m is provided with a catch box; the teeth.of which: take into
the catch box n, which slides on a key in the shaft j. These catch boxes' are
held into gear; with each: other by a spring, one end of which rests against
one of the bearings of the shaft j, and the other end against the sliding catch-
box n, which is moved in and out of gear by means of the lever o, suspended
from a stud p:fixed to:a bracket q, bolted to the side frame of the 'headstock.
, is a forked piece taking into a "groove. provided in the catch box'n, 'and
having a round pin fitting into a hole in the. lever. o, the lower end of which is
made with a latch s; as seen in Figure 13, the object of which will be
explained hereafter. At the top of the upright shaft.b is fixed' a'mitre wheel t
gearing into. a similar wheel on the shaft u, which has 'a' pinion keyed on it
driven by the wheel loose on the shaft w,.but connected with it when the
carriage goes in by the ratchet wheel a keyed on the shaft w, and the click z
fitted on a pin in the wheel The rack pinion 1 is keyed on the shaft.tv,
and the rack:2; into which it gears, is secured by brackets to the frame of the
mule headstock: The wheel gears into the pinion 3; fixed to the mitre
wheel: 4 which forms part of the differential motion, similar to that already
described with reference to the coiling and slubbing frames. 5 is. the
larger spur wheel of 'the differential motion gearing into the pinion 6,
fixed upon the same-shaft as the friction disc c. The horizontal shaft' 7,
seen in Figure 12, is attached to the travelling carriage of a self-acting
mule, and it gives motion to the various 'parts for winding on in the
putting up of the carriage, by means of a pinion 8, which takes into 'and 'is
driven by a carrier 9, and this takes into another carrier 10, working into
the pinion 11, fixed on the boss of the loose mitre wheel of the differential
motion. The pinion 8 is loose on the shaft 7, but fast to a catch box 22:
The catch box 23. slides on the shaft 7, and is connected with it by a groove
and key in the ordinary manner. 24 is a'lever:with the fork taking into a
groove provided in the catch box :28; and 25 is a pall for holding the catch
-box'23-into or out of gear with the catch box'22. 26, in Figure 12; repre-
sents a "section of the long lever used in Roberts's mules; by the agency of
which, and of the springs usually employed for that purpose, the winding-
on motion is put into gear at the commencement of the running in of: the
carriage, 27 is a roller fitted on a stud projecting from the lever 24, against
which the above-mentioned. springs act when throwing the catch box 23 into
or out of gear. 12. represents a bracket bolted to the bottom plate of the

page_text: carriage 'for supporting the box 13, in which is placed "a screw 14, working
in bearings provided at each, end of the box 13: "The screw nut 15 is moved
backwards and forwards on the screw 14 by means of a ratchet wheel 16,
fixed' on one end of the screw; the click 17-hinges on a stud fixed in the
end of the elbow lever 18; the fulcrum of which is: a projection-of-the
screw 14: Upon the upper part of the screw nut 15. is bolted a bent
plate 19, seen best in the detached plan view, and when the carriage is nearly
out, this plate 19' acts upon the latch s and-lever o; and pushes them in the
direction of the arrow shewn in Figure 14; thereby disengaging the 'catch
box n'from the catch box on the back of the pinion m. When the carriage
has arrived at the end of its stretch, the bent plate '19 will have passed
beyond the latch's, and the lever o and catch box n; will have resumed; the
position shewn in Figure. 14, and at the same time the elbow lever 18 will
have slid sufficiently up the inclined planė 20, bolted to the: frame of the
headstock, and seen in dotted lines in Figure 13 to elevate the click 17.as
much as is required, to move the ratchet wheel 16 through the thirtieth part.
of a revolution, or more or less as may be found convenient, to suit the
winding 'on of the yarn under: operation. When the carriage" returns towards
the drawing rollers, the catch 21 of the plate 19: comes', against-the-latch's;
which hinges on a stud fixed on the lever o, and allows the plate-19 to pass
without altering the position of the said lever; the elbow lever 18 will at the
same time slide down the inclined plane. 20, and the click 17 will return
into the position for taking hold of another tooth of the ratchet wheel ·:16.
At the commencement of a cop, 'the .long levere is about in a horizontal
position, and the roller ie*,at the end of it is then at the lowest part of the
scrole f, consequently the roller d' is working near the largest diameter of the
disc c. The screw nut 15:in the box 18 will be near to the end of the screwil 4:
furthest from the headstock, and the plate .19,-by: coming sooner into: contact:
with 'the latch 8, will hold. the catch box n longer out of gear than it does
towards the end of the cop, when the: screw ñut 15, by the action of,the-ratchet
wheel 16, click 17, elbow lever :18; and inclined plane 20--has been brought
closer to the headstock of the mule, and the plate 19, by coming later in contact
with the latch s,' will. hold the catch box in for a 'less-space of time out of
gear. A's the wheel 7 on the end of the back shaft imparts a rotary motion:
to the scroll by the means herein-before described, it will be evident that,
by holding the catch box n out of gear for more time at the beginning of
a'cop than at the end, the scroll f will at the beginning of a cop move
through rather less part of a revolution than it does at, the end.for each
time the carriage performs one stretch. As long as the carriage is going out

page_text: the various parts of the mule are driven in the ordinary manner, but as soon
as the carriage has got to the end of its stretch, the catch box 23, which in
going out was in the position shewn in Figure 12, is thrown into gear with
the catch box 22, and on the putting-up motion commencing, the pinion 1,
gearing into the rack 2, becomes the driver; and through the medium of the
:shaft wi ratchet wheel x, click z, spur wheel v, and pinion in which it works
on the shaft u, mitre wheels t, and upright shaft b, gives motion to 'the
-roller a and friction disc. c, the 'varying velocity of which is transmitted to
the shaft 7 through the differential wheels and carriers 10 and 9, as already
.described, the shaft 7 communicating its motion to the winding-ón drum 29,
by the mitre wheels 28, seen in Figure. 12. It has already been said, that the
lever e at the commencement of the cop is nearly in a level position, owing to
'the friction roller e* being 'near the lowest part of. the scroll f; it is, however,
necessary 'to remark, that as the formation of the cop progresses, the scroll
is gradually turned round by the means already described, until it, performs
about one entire revolution, at which time the roller e* is at the top of the
scroll f, and the lever e is in its most inclined position, because the carriage,
in ""running in," has to impart the greatest variation in the speed to the
winding-on pulley 29, to compensate for the varying 'diameters of the cop,
which is here represented as being about half completed.
Having now described the nature of my said Invention, and the manner
in which the same is to be performed, I declare that I claim as of my
Invention,
First, the arrangements I have herein-before described, or any combination
thereof, for combining and working together in the same machine the g
differential motion and the friction disc motion in connection with a curve
scroll or inclined plane, whether the said motions be applied to the machines.
shewn in the Drawings hereunto annexed, or to any other machines used in
preparing, spinning, and doubling, cotton; wool, and other fibrous substances.
Secondly, I claim the new combination and arrangement of parts forming 8
apparatus for placing the rovings or yarn in uniform coils between the plates
marked wand 17 in the coiling frame herein described, and in giving the
required pressure to the coils by the springs 45. And I would have it under-
stood, that I do not confine myself to the precise forms or details here given,'
nor to the materials of which the different parts are composed, so long as the 3
character of the Invention be retained.
In witness whereof, I have hereunto set my hand and seal, the Sixteenth
day of December, in the year of our Lord One thousand eight hundred
