En the Matter of a Patent granted, to SAMUEL CUNLIFFE, LISTER, of
Manningham, near Bradford, in the County of York, and GEORGE
EDMOND DONISTHORPE, of Leeds, in the same County, Manufacturer.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we; the "said
SAMUEL CUNLIFFE LISTER and GEORGE EDMOND DONISTHORPE, send greeting:?
WHEREAS Letters Patent, bearing date and duly sealed at Westminster,
the Twentieth day of March, One thousand eight hundred and fifty," were
granted to us, Samuel Cunliffe Lister and George Edmond. Donisthorpe; for
our Invention of "IMPROVEMENTS IN PREPARING AND COMBING WOOL AND OTHER
FIBROUS MATERIALS" And whereas a Specification of the same was duly
enrolled in Her Majesty's High Court of Chancery on the Twentieth day of
September, One thousand eight hundred and fifty: And whereas since the
enrolment of the said Specification we have ascertained that certaiii improve-
ments described therein do not possess such an amount of utility as to make
us desirous of retaining the parts of the Specification relating thereto; and we
are advised, for the reasons aforesaid, to enter a Disclaimer of the parts of our
said Specification hereafter mentioned.
-
NOW KNOW YE, that we, the said 'Samuel Cunliffe Lister and George
Edmond Donisthorpe, do, with the leave of Sir Richard Bethell, Knight, Her*
Majesty's Solicitor General, certified by his fiat and signature; disclaim the"
words "one part of" which occur at an early part of our said Specification;

page_text: also the parts of the Specification commencing with the words "and such part
may be used in preparing wool," to and including the words "constitutes
another part of our Invention," which occur at the end of the Specification;
and it has been objected to our said Specification that detaching portions of
wool or fibrous materials by nipping apparatus, such as was described in the
Specification of a Patent granted to Josué Heilmann, on the Twenty-fifth
February, One thousand eight hundred and forty-six, is claimed by us as being
part of our Invention; and it has also been objected, that the mechanical parts
which compose the combined machinery described in our said Specification
are each claimed as part of our Invention; for which reasons we introduce the
words "as herein-before described" before the words "combined with the use
"of drawing out detached quantities of fibres therefrom is a highly useful
part of our Invention," and at the end of our said Specification we add the
following Disclaimer (that is to say):-
"
"We disclaim as being part of our Invention, the detaching of quantities
"of wool or other fibrous materials by nipping apparatus; and we also dis-
"claim as being any part of our Invention, the separate mechanical parts of
"which the combined machinery, described in our said Specification, is com-
posed; and we declare that the Specification altered as above mentioned
"will be as follows (that is to say):-

Now know ye, that in compliance with the said proviso, we, the said
Samuel Cunliffe Lister and George Edmond Donisthorpe, do hereby declare
that the nature of our said Invention, and the manner in which the same is
"to be performed, are fully described and ascertained in and by the following
"statement thereof, reference being had to the Drawings hereunto annexed,
"and to the figures and letters marked thereon, that is to say :-

"In the Specification of a Patent granted to me, the said George Edmond
Donisthorpe and John Whitehead, bearing date at Westminster, the
Eighth day of May, One thousand eight hundred and forty-nine, part of the
Invention is stated to consist in a mode of preparing wool by taking hold
of, drawing out, and thus detaching and straightening, by mechanical means,
"successive small quantities of fibrous materials, which portions were again
"accumulated and laid on to brushes or other holders or combs, for the
purpose of obtaining slivers. Now our present Invention consists of
improvements in arranging apparatus, by which such mode of treating wool
"and other fibrous material may be more advantageously carried into effect.
"And in order that the improvements may be fully understood, we will
proceed to describe the means pursued by us."

We have not thought it necessary to show a complete machine for comb-
ing wool, as such is now well understood. We have therefore only shewn
"those parts to which our improvements apply. Figure 1 shews a plan,
Figure 2 a section, Figure 3 a side view, and Figures 4, 5, and 6, de-
"tached views of machinery according to our present improvements.

a, a,
are the carrying combs which receive the wool as fed in from the nipping
"or holding means in detached pieces; and as the wool is accumulated on
"these combs it is conducted forward to be drawn off in the ordinary
66 manner. The nipping means consist of the bars b, b, (which alternately
come into operation) and the endless band or apron c, which receive the
"wool between them, and draw out portions therefrom, as delivered by the
"combs d, d. When the instruments b, c, have taken the portion of wool
"and brought it towards the circle of combs, one of the brush surfaces
alternately comes into position to take such portion of wool, and place it on
"to the combs a. The various parts are driven in the following manner :-
e is the main axis of the apparatus which receives motion by means of a
strap or band acting on the drum e. Upon this shaft e are fixed the
bevilled pinions e, which take into and drive the bevilled pinions f, affixed
on the axis f, and thence to the axis f, upon which are formed the
"screws for giving motion to the gills d, as is well understood. Upon
the shaft e is also affixed the pinion e, which, by means of the intermediate
wheel e, gives motion to the toothed wheel b', affixed on the axis of the
roller, which carries the bars b, such bars being formed, as shewn, to be
capable of sliding freely within the cylinder or roller b; and they have a
"tendency constantly to be pressed outwards from the surface of the
cylinder b², by reason of the springs 3, which are constantly pressing against
the inner surfaces of the bars b, as shewn; but the bars are controlled
in their movement by means of the rims of the plates 6, which are affixed
to the framing of the machine by means of the pillars 65, and there are
cam surfaces on the inside of these rims against which the rollers 6º, carried
26
<
66
it
by the bars b, run, thus controlling their motion; and it will be seen that
the bars beach come out from the surface of the cylinder or drum be, just
as (in the revolution of the roller 62) they come round to the point where
the gill combs deliver the wool. The wool is then nipped between the
bar 6 (which for the time being is acting with the apron c) and the
apron c, which travels forward with the instrument 6, drawing out and
detaching a quantity of wool from the screw gills. The apron c is con- .
ducted over the upper edge of the plate c', over the roller c, which

page_text: "receives motion so as to travel at the same surface speed as the cylinder
"or roller.b, by means of the. toothed wheel b, on. the axis of the roller 6,
taking into, and driving the pinion ³ (shown by red lines), affixed on the
"axis of the roller c. Thence the apron c passes over the guide roller c, and
down and under the roller c. The lower edge of the plate ch is, supported
6
in bearing: c, as,shown, and the tendency of the upper edge of the plate c
by reason of the apron c, is constantly to..rest against the roller c; but
when the nip is to take place, to detach a portion of wool or other fibrous
"material which has been brought forward by the gill combs, it is necessary
"that the upper edge of the plate c¹, with the part of the apron c which, for
"the time is passing over that edge, should be in position under (as shewn
"by the Drawings), .and thus form a corresponding holder to the bar 6 in
"effecting such nip. For this purpose there are. ears c attached, one on
"each side of the plate c', and projecting on each side of the machine.
"These ears have holes, in which slide the ends c* of the excentric rods c³.
The other end of each of these rods embraces an excentric c, affixed
"on the shaft c. In the revolution of these excentrics, the end c*, of the
"rods c slide freely in the holes formed through the ears c. But these
rods, just when the nip is to take place, are arranged to draw the ears,
and consequently the plate c', a short distance towards the gill combs, as
shewn by the Drawings. Then, as the excentrics revolve with the shaft e;
the rods slide in the ears, and the plate c' goes slightly forward. with the
apron to the roller c³, which then acts with the apron in the further move-
ment of the apron and the nipper bar b. As the detached portion of
wool or other fibrous material under operation comes forward with the
holding instruments b, c, the edge of such detached portion which was
nipped by those holding instruments is then received alternately on to
"one of the brush surfaces g, which are carried by the frame g', and this
frame g is affixed to the spindle g, which is carried so as to be capable
of being adjusted in position by means of the framing as shown; and it has
"affixed to it the toothed wheel g³, which takes into and receives motion from
"toothed wheel. The brushes then, as the frame g¹ moves partly round
"on its axis g³, it takes the detached portions of wool or other fibrous
"material under operation, and successively deposits them on the teeth of
"the passing comb-a, where they are accumulated, and so soon as such
"detached portions are brought on to the combs a, they are pressed down
"into the teeth by means of the brush h, which then recedes out of the way
"for another portion of wool or other fibrous material to be placed on the
comb, which is in like manner pressed down into the teeth a, and so on each
65

page_text: "successive portion of wool is pressed on to the combs a by the brush .
This brush h is affixed. to one end of the lever h', the other end of which
is supported so as to turn upon the pin , which passes through it and
"through the standard ³, as shewn; and the lever h' is connected by the
rod h to one end of the lever h, which turns upon the -axis ; and at
the other end; by means of a link h, is connected to the crank he formed
"on the axis h, which is supported in the framing of the machine, and
receives motion from the axis of the roller c by means of the pinion h¹0;
affixed on that axis, taking. into and driving the intermediate wheel ",
"which takes into and gives motion to the toothed wheel h, affixed on the
axis hº."

"We have shewn the parts working in connection with a circle of passing
combs, but we do not confine ourselves to that arrangement of combs, as in
place of the passing combs being circular they may be in straight lines, and
in place of their being moving combs they may be fixed, and only removed
"when charged or filled with wool, such wool to be afterwards drawn from
"them in the ordinary manner. But when a circle of teeth is employed, we'
have found it better that the brushes g, as they come round to deposit their
"detached portions of fibrous material on to the combs a, should conform to
the figure of the passing combs, whilst in taking such detached portions from
"between the holding instrument, they should be straight on the surface.. For
this purpose we have formed each of the brushes g in three portions, and so
as to have motion given to them in the revolution of the frame g¹ in the
following manner :-Each of the outer portions of the brushes g turns upon
a centre g: The two centre ones are connected together by means of
plates g, one on each side, as shewn, and they have also other plates, or
bars 9,.the-ends of which project beyond the length of such middle portions
"of the brushes y; and such projecting portions have slotted openings formed
"there through, to receive the headed pius or screws go, by which the outer
"and centre portions of each of the brushes g is connected together, whereby
any motion given to the centre portions will, control the position of the end
portions. One of the brushes g is constantly pressed into a straight line by
means of the spring g', whilst the other has a constant tendency to be drawn
into a curved line. g is,a lever turning upon the, centre.g, and carried by
the frame g. One end of this lever presses against the centre portions of
"one of the brushes g; the other end of this lever g³ passes .iuto, the course

"
formed in the plate g. This course is formed as a cam course, to give
"motion to the, lever g³, so that when the brush against which this lever g³
works, may be pressed into a straight line at the time of its passing the
apron c, whilst the other brush will have a curved form given to it. When

page_text: "
"in the revolution of the frame g', the brushes each point in an opposite
"direction to that in which they are shewn, the lever 98 will be in such a
position with respect to the course in the plate glo, that the spring will be
"allowed to act to press the brushes g (against which that spring acts), into
a straight line."

"We would here state, that although we have shown and described screw-
gill combs as the teeth through which the fibrous material is to be pre-
viously conducted, and from which it is subsequently withdrawn in detached
portions to be fed into teeth of other combs or instruments, we do not confine
"ourselves thereto, as the same may be varied without departing from our
"Invention; and in withdrawing the detached portions of wool or fibrous
material by the nipping or holding instruments from the teeth employed,
"the noil or refuse will be left in the teeth used, excepting where the nippers
or holders have hold thereof. Then in the continuous movement of the
gills or gill combs, the noil or other refuse left from the portion last detached
will be brought forward to be taken hold of at the next nipping. And such
nipped portions containing the refuse will be laid on to the combs a, with
the noil or other refuse, and the cleansed or drawn out ends of all such
"detached portions of wool or other fibrous material (which have been
"drawn through the gill or other combs used) will, when on the combs a, be
projecting out from those combs a, so that in the drawing off of the wool
or other fibrous material under operation from the combs a, the noil which
was in the ends of those accumulated portions of wool or other fibrous
€6 matters will be left in the combs a. We would remark, that the use of
screw gills or series of teeth acting in like manner to bring up successive
quantities of fibre when, as herein-before described, combined with the use
"of drawing out detached quantities of fibres therefrom, is a highly use part
"of our Invention."

we, the said Samuel Cunliffe Lister and George Edmond Donisthorpe,
or one of us, should cause a particular description of the nature of our
said Invention, and in what manner the same is to be performed, by an
instrument in writing under our hands and seals, or under the hand and
seal of one of us, to be inrolled in Her said Majesty's High Court of
Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
'NOW KNOW YE, that in compliance with the said proviso, we,
the said Samuel Cunliffe Lister and George Edmond Donisthorpe, do
hereby declare, that the nature of our said Invention, and the manner
in which the same is to be performed, are fully described and ascertained
in and. by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say:
In the Specification of a Patent granted to me, the said George
Edmond Donisthorpe and John Whitehead, bearing date at West-
minster, the Eighth day of May, One thousand eight hundred and
forty-nine, part of the Invention is stated to consist in a mode of pre-
paring wool by taking hold of, drawing out, and thus detaching and
straightening by mechanical means successive small quantities of fibrous
material, which portions were again accumulated and laid on to brushes
or other holders or combs, for the purpose of obtaining slivers. Now
one part of our present Invention consists of improvements in arranging
apparatus by which such mode of treating wool and other fibrous
material may be more advantageously carried into effect: And in order
that the improvements may be fully understood, we will proceed to
describe the means pursued by us.
DESCRIPTION OF THE DRAWINGS.

page_text: only shewn those parts to which our improvements apply. Figure 1,
shews a plan; Figure 2, a section; Figure 3, a side view; and Figures
4, 5, and 6, detached views of machinery according to our present
improvements. a, a, are the carrying combs which receive the wool as
fed in from the nipping or holding means in detached pieces; and as
the wool is accumulated on these combs, it is conducted forward to be
drawn off in the ordinary manner. The nipping means consist of the
bars b, b, (which alternately come into operation,) and the endless band
or apron c, which receive the wool between them, and draw out portions.
therefrom as delivered by the combs d, d. When the instruments b, c,.
have taken the portion of wool, and brought it towards the circle of
combs, one of the brush surfaces alternately comes into position to take
such portion of wool and place it on to the combs a.
The various parts
are driven in the following manner: e, is the main axis of the apparatus.
which receives motion by means of a strap or band acting on the drum.
e; upon this shaft e, are fixed the bevelled pinions e, which take into
and drive the bevelled pinions f, affixed on the axis f¹, and thence to.
the axis f, upon which are formed the screws f, for giving motion to.
the gills d, as is well understood. Upon the shaft e, is also affixed the
pinion e³, which, by means of the intermediate wheel e, gives motion to
the toothed wheel ', affixed on the axis of the roller , which carries
the bars b, such bars being formed as shewn to be capable of sliding
freely within the cylinder or roller ; and they have a tendency con-
stantly to be pressed outwards from the surface of the cylinder, by
reason of the springs b, which are constantly pressing against the inner
surfaces of the bars b, as shewn. But the bars b, are controlled in their
movement by means of the rims of the plates, which are affixed to
the framing of the machine by means of the pillars; and there are
cam surfaces on the inside of these rims, against which the rollers 6º,
carried by the bars b, run, thus controlling their motion; and it will be
seen that the bars b, cách come out from the surface of the cylinder or
drum b, just as (in the revolution of the roller b) they comic round to
the point where the gill combs deliver the wool. The wool is then
nipped between the bar b, (which for the time being is acting with the
apron c,) and the apron c, which travels forward with the instrument b,
drawing out and detaching a quantity of wool from the screw gills,

page_text: The apron c, is conducted over the upper edge of the plate c', over the
roller, which receives motion so as to travel at the same surface speed
as the cylinder or roller 2, by means of the toothed wheel , on the axis
of the roller, taking into and driving the pinion c, (shown by red
lines,) aflixed on the axis of the roller c. Thence the apron c, passes
over the guide roller c', and down under the roller c. The lower edge
of the plate c', is supported in bearing c", as shewn; and the tendency
of the upper edge of the plate c', by reason of the apron c, is constantly
to rest against the roller. But when the nip is to take place to
detach a portion of wool or other fibrous material which has been
brought forward by the gill combs it is necessary that the upper edge
of the plate c', with the part of the apron c, which for the time is
passing over that edge, should be in position under (as shown by the
Drawings), and thus form a corresponding holder to the bar b, in
effecting such nip. For this purpose there are ears c, attached one on
cach side of the plate c', and projecting on each side of the machine.
These ears have holes in which slide the ends cx, of the excentric rods
8. The other end of each of these rods c, embraces an excentric cº,
affixed on the shaft c. In the revolution of these excentrics, the
end c*, of the rods c, slide freely in the holes formed through the
ears c. But these rods, just when the nip is to take place, are arranged
to draw the cars, and consequently the plate c', a short distance towards
the gill combs, as shewn by the Drawings. Then as the excentrics
revolve with the shaft e, the rods c, slide in the ears, and the plate c',
goes slightly forward with the apron to the roller c, which then acts
with the apron in the further movement of the apron and the nipper
bar b. As the detached portion of wool or other fibrous material under
operation comes forward with the holding instruments b, c, the edge of
such detached portion which was nipped by those holding instruments
is then received alternately on to one of the brush surfaces g, which
are carried by the frame g'; and this frame g', is affixed to the spindle
g, which is carried so as to be capable of being adjusted in position by
means of the framing as shown; and it has affixed to it the toothed
wheel, which takes into and receives motion from the toothed
wheel. The brushes then, as the frame g', moves partly round on its
axis g, it takes the detached portions of wool or other fibrous material

page_text: under operation, and successively deposits them on the teeth of the
passing comb a, where they are accumulated; and so soon as such
detached portions are brought on to the combs a, they are pressed
down into the teeth by means of the brush h, which then recedes out
of the way for another portion of wool or other fibrous material to be
placed on the comb, which is in like manner pressed down into the
teeth a, and so on, each successive portion of wool is pressed on to the
combs a, by the brush h. This brush h, is affixed to one end of
the lever ', the other end of which is supported so as to turn upon the
pin, which passes through it and through the standard, as shown;
and the lever h¹, is connected by the rod h', to one end of the lever h³,
which turns upon the axis ", and at the other end by means of a link
, is connected to the cranks, formed on the axis h, which is sup-
ported in the framing of the machine, and receives motion from the
axis of the roller c, by means of the pinion h¹, affixed on that axis
taking into and driving the intermediate wheel h", which takes into
and gives motion to the toothed wheel 2, affixed on the axis hº.
We have shown. the parts working in connection with a circle of
passing combs, but we do not confine ourselves to that arrangement of
combs, as in place of the passing combs being circular they may be
in straight lines; and in place of their being moving combs they may
be fixed, and only removed when charged or filled with wool, such wool
to be afterwards drawn from them in the ordinary manner. But when
a circle of teeth is employed we have found it better that the brushes, g,
as they come round to deposit their detached portions of fibrous ma-
terial on to the combs a, should conform to the figure of the passing
combs, whilst in taking such detached portions from between the
holding instrument they should be straight on the surface. For this
purpose we have formed each of the brushes g, in three portions, and so
as to have motion given to them in the revolution of the frame g', in the
following manner-Each of the outer portions of the brushes, 9. turns
upon a centre g'. The two centre ones are connected together by
means of plates g*, one on each side, as shewn; and they have also
other plates or bars g, the ends of which project beyond the length of
such middle portions of the brushes g, and such projecting portions have

page_text: slotted openings formed therethrough to receive the headed pins or screws
by which the outer and centre portions of each of the brushes g, is
connected together, whereby any motion given to the centre portions
will control the position of the end portions. One of the brushes g, is
constantly pressed into a straight line by means of the spring g', whilst
the other has a constant tendency to be drawn into a curved line. gs,
is a lever turning upon the centre g, and carried by the frame g¹; one
end of this lever presses against the centre portions of one of the
brushes g. The other end of this lever 98, passes into the course formed
in the plate go. This course is formed as a cam course to give motion
to the lever g³, so that when the brush against which this lever g, works
may be pressed into a straight line at the time of its passing the apron c,
whilst the other brush will have a curved form given to it. When in
the revolution of the frame g', the brushes each point in an opposite
direction to that in which they are shewn, the lever g, will be in such
a position with respect to the course in the plate g10, that the spring
will be allowed to act to press the brushes g, (against which that spring
acts) into a straight line.
We would here state, that although we have shown and described
screw gill combs as the teeth through which the fibrous material is to
be previously conducted, and from which it is subsequently withdrawn
in detached portions to be fed into teeth of other combs or instruments,
we do not confine ourselves thereto, as the same may be varied without
departing from our Invention; and in withdrawing the detached por-
tions of wool or fibrous material by the nipping or holding instruments
from the teeth employed, the noil or refuse will be left in the teeth
used, excepting where the nippers or holders have hold thereof. Then
in the continuous movement of the gills or gill combs, the noil or
other refuse left from the portion last detached will be brought forward
to be taken hold of at the next nipping; and such nipped portions con-
taining the refuse will be laid on to the combs a, with the noil or other
refuse; and the cleansed or drawn out ends of all such detached portions
of wool or other fibrous material (which have been drawn through the
gill or other combs used), will, when on the combs a, be projecting out
from those combs a, so that in the drawing off of the wool or other fibrous
"

page_text: material under operation from the combs a, the noil which was in the
ends of those accumulated portions of wool or other fibrous matters will
be left in the combs a. We would remark that the use of screw gills
or series of teeth acting in like manner to bring up successive quan-
tities of fibre, when combined with the use of drawing out detached!
quantities of fibres therefrom, is a highly useful part of our Invention,
and such part may be used in preparing wool or other fibre without
accumulating the separated quantities as described; for in place thereof
the ends of the separated quantities may be placed one. on the..other,'
and thereby pieced up by causing these detached quantities to be 'de-
positeil on to a travelling apron or otherwise; but we consider the use:
of a travelling apron to receive such detached quantities a 'highly im
portant part of our Invention.
::
,
Another part of our Invention consists in treating wool and other;
fibrous materials in like manner to what we have herein-before described;!
by detaching portions thereof after such wool or other material has been
operated upon by teeth or combs in such manner as, to withdraw noil.
And we would here state that we are aware that it has been proposed
to arrange machinery, and a Patent has been taken for the same by
Josué Heilmann, dated the Twenty-fifth day of February, One thousand
eight hundred and forty-six, in which, the wool whilst being fed into a
machine is held for a short-time, and the ends are operated upon by
rotating combs to withdraw noil; then such portion of wool is taken
hold of by rollers, and detached or withdrawn, and again-held between
the rollers whilst the comb teeth operate to remove the noil from and
clear the other ends of the fibres of such detached quantity; and in like
manner successive small quantities are to be operated on, and such
quantities so operated upon are by the machine connected together or
pieced up end to end and removed in the form of a sliver. Now, we
have found it to be a great advantage, in thus treating wool and other
fibrous matters by withdrawing noil previous to taking detached
portions, that such detached portions should be. accumulated one on the
other on brushes..or in. combs or other pointed surfaces, thence to be.
drawn off into a sliver; for this purpose I apply, by preference, to such
descriptions of machinery a comb caused to pass slowly, so that the
successive combed out quantities shall be fed or placed therein, and

page_text: thus accumulated so as to allow of good slivers to be drawn off in the
ordinary manner of drawing wool from combs; or in place of combs
or teeth, a rotating brush may be employed, as described in the said
former Specification. And it is the accumulating of wool or other
fibrous material upon combs or other pointed surfaces, when such
fibrous material has been so treated, that constitutes the peculiarity of
this part of our Invention.
We have also found that when we work wool or other fibrous
material according to the means above described or mentioned, that is,
by detaching, by suitable holding surfaces, successive portions thereof,
and then accumlating such portions on any suitable surface or comb,
that such wool or other fibrous material should be subjected to a
carding process; and it is the subjecting wool when to be treated by a
process of obtaining separated detached portions to a previous carding
process that constitutes another part of our Invention.
In witness whereof, we, the said Samuel Cunliffe Lister and
George Edmond Donisthorpe, have hereunto set our hands and
seals, this Twentieth day of September, in the year of our Lord
One thousand eight hundred and fifty.
