page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
SAMUEL Cunliffe LISTER and JAMES AMBLER, both of Maningham, in
the Parish of Bradford, in the County of York, Manufacturers, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria,
by Her Royal Letters Patent under the Great Seal of the United
Kingdom of Great Britain and Ireland, bearing date at Westminster
the Second day of February, One thousand eight hundred and fifty-two,
in the fifteenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Samuel Cunliffe Lister and
James Ambler, our exors, adññors, and assigns, Her especial licence,
full power, sole privilege and authority, that we, the said Samuel
Cunliffe Lister and James Ambler, our exors, adiñors, and assigns, or
such others as we, the said Samuel Cunliffe Lister and James Ambler,
our exors, adñiors, 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 expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed,

page_text: our Invention of "IMPROVEMENTS IN PREPARING AND COMBING WOOL
AND OTHER FIBROUS MATERIALS;" in which said Letters Patent is con-
tained a proviso that we, the said Samuel Cunliffe Lister and James
Ambler, or one of us, shall 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 James Ambler, lo 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:
Our Invention relates, first, to preparing wool and other fibrous
materials, and consists in beating it with a machine having rods
turning upon axes, fixed upon a strap or belt or chain, travelling at a
high velocity round two drums, the larger of the two being the driving
drum. The wool or other fibrous material to be cleansed passes slowly
past on a suitable travelling apron or table (which I prefer to be of
network to allow of the dirt falling through), and the rods as they
pass over the smaller of the two rollers are thrown over on to the
wool or other fibrous material, and thereby beat and cleanse it from
dirt. Figure 1 shows a side view, and Figure 2 a plan of so much
of a machine as will serve to illustrate this part of the Invention. a,
is the driving drum, which is affixed to the axis a', and receives
motion in any suitable manner from a steam engine or otherwise.
Over the drum a passes the band b, to which it gives motion. The
rods c are affixed by hinge joints to the band b; d, is the travelling
apron which may be formed into an endless cloth, and be supported by
rollers so as to travel past the front of the beating rods c; or, in place

page_text: of an endless apron, the wool or other fibrous material may be sup-
ported during the beating action by a travelling table; but in either
case we prefer that the means used for supporting the wool or other
fibrous material during the action of beating be formed reticulate to
admit of the loose particles passing away freely.
"
Secondly, our Invention consists in using that description of "gas'
commonly termed "water gas " for heating combs used in combing
machinery on account of its peculiar character in being free from
smoke. In applying this part of our Invention we prefer to adopt
the process of manufacture described in the Specification of a Patent.
granted to Stephen White, Fifteenth April, One thousand eight hundred
and forty-seven, and we conduct the gas to the combing apparatus
by like means to what have been lieretofore adopted in applying the
ordinary coal gas to wool combing machinery for the purpose of
heating the combs to facilitate the processes of combing. But by
adopting this description of gas to heating combs in such machinery
we have found a great advantage as respects economy and cleanliness.
Thirdly, our Invention relates to feeding wool and other other
fibrous material on to passing combs. In some instances we find it.
advantageous to use a combined nipping and combing action, that is to.
say, that when the wool or other fibrous material is brought forward.
and projects out of the screw gill combs, a comb is made to penetrate
through the projecting fibres so as to comb out the ends for a certain
distance from the gill feeding apparatus, and then a thin plate of iron
is inserted between the rows of the teeth so as to act as a nipper, and
assist the teeth of the comb in detaching a portion of wool or other
fibrous material, which may be transferred to another comb to be drawn
off, or otherwise. Figure 3 shows a sectional view of parts of apparatus,
which for the most part are similar to arrangements of machinery shown
in the Specifications of Patents recently granted to me (Samuel Cunliffe
Lister). ff. are the feed rollers, which conduct the wool or other
fibrous material into position, to be taken and carried forward by the
gill teeth g, which have motion given to them in any suitable manner
as is well understood, and the wool or other fibrous material as it
projects beyond the face of the teeth of the gills is then entered by the

page_text: comb teeth h, which are carried by a bar i, which with the bar jare
similarly carried and actuated to like bars in the said former machines,
except that the bar i has a motion given to it by which, when it comes
up to the gill teeth, as shewn by the Drawing, it rises into the wool or
other fibrous material, and then when the bar i, with the teeth h, go
out, drawing with them the wool or other fibrous material nearly to the
position indicated by red lines, the bar j is caused to descend and nip
the wool or other fibrous material, which, when the parts come into
the position indicated by the red lines, is taken by the carrying comb k,
and laid on to the passing comb 1, in like manner to what is described
in such former Specification. By this means we effect a partial
combing of the fibres in the act of transferring them to the passing
combs.
In place of the above arrangement the screw gill comb itself may be
made to act in a similar manner by having the screws (by which the
gills are caused to travel) made with a varying or progressive pitch;
that is to say, supposing the screws for the first part, that is (the end
at which the fibrous material is fed into the gills), to be half inch pitch,
and then to be made five or six inch pitch, when a gill comb arrives at
the coarse part of the screw it will, according to the degree of coarse-
ness, travel rapidly away from the gill combs at present being acted on
by the finer portion of the screws, and thus detach or partially detach
a portion of the wool or other fibrous material from the other gills, and
by inserting a thin piece of iron in a convenient manner) between the
rows of teeth of the gill comb, and causing it to press upon the wool
or other fibrous material, it will act as a sort of nipper, and assist
the teeth in detaching a portion of wool or other fibrous material,
which may be taken by nipping means, such as above referred to, and
described in the Specifications of Patents granted to me (Samuel Cunliffe
Lister), and which are now in use, and placed upon a comb in the usual
way, to be afterwards drawn off. In some cases when using combs in
the lower nipping bar to receive and detach wool or other fibrous
material supplied from gill teeth we dispense with the use of the
upper nipping bar, but in such cases we prefer to arrange the bar i,
with its ends turning upon centres, and so that when it has travelled

page_text: slightly away with its wool or other fibrous material it shall incline with
the points of the teeth h farther away than the heads from the gill
teeth from which the fibrous material is being drawn, by which a better
holding is obtained to the wool or other fibrous material during the
separation of the fibrous material from the gill teeth, and such wool or
other fibrous material may be accumulated in successive layers upon
the detaching comb, which will then be removed to have the wool or
other fibrous material drawn off from time to time, or it may be by it
transferred to another carrying comb to be drawn off.
Another mode we adopt to separate the wool or other fibrous mate-
rial as it is drawn through gill teeth by nipping means is by a sort of
plunger or detacher, and which we find highly useful in assisting the
nipping instruments now in use to separate the wool or other fibrous
material from the gill combs; and in order that it may be properly
understood we will describe the Drawing, Figure 4. ff, are the feed
rollers conducting the wool or other fibrous material into the gill teeth
9, whence it is received between the nipping jaws h, i, as shown and
described in the Specifications granted to me (Samuel Cunliffe Lister);
but in this case the nippers having drawn out the wool or other fibrous
material a certain distance from the gill teeth, the plunger bar j
descends, as shown by red lines, and effects the separation of the fibres;
the wool or other fibrous material is then taken by means of the carry-
ing comb k, and placed upon a comb l.
The fourth part of our Invention relates to improvements in an
arrangement of machinery such as was described in the Specification
of a Patent granted to Charles Augustus Preller, July Seventh, One
thousand eight hundred and forty-two, in which a series of combs were
placed in succession across the periphery of a drum for the purpose
of receiving wool from feed rollers, and then combing it with a
cylinder covered with card teeth; and the improvement consists in
arranging the bars in which such comb teeth are set so that they
may turn upon axes formed at the ends of such bars in a similar
manner to the plan patented by James Noble, March Twenty-ninth,
One thousand eight hundred and thirty-six; and just as those comb
teeth pass the feed rollers, as also when passing the cylinder or drum

page_text: covered with card teeth, we control them so that in one case the
points of the teeth may better enter the wool or other fibrous material
to be operated on as it is fed in, and then the points may be drawn
inwards so that the heads of the comb teeth which hold the wool or
other fibrous material may come close to the card surface.
Fifthly, our Invention relates to transferring wool and other fibrous
material from one carrying comb or set of carrying combs to another in
the act of working the same. Figure 5 shows a diagram of this part of
the Invention. a, is the section of a passing comb which has been sup-
plied with wool by any suitable means, and when the wool comes to
the transferring and working comb b, that comb brises into the wool
or other fibrous material brought up by the passing comb a, and then
draws out such wool or other fibrous, and the wool or other fibrous
material so separated and drawn out is then in the movement of the
parts carried by the comb b, as shewn by dotted lines, and laid on to
another comb or set of combs c; but it will be seen that the ends of
such wool or other fibrous material which were inwards whilst on the
combs a will, when transferred to the combs c, be outwards. The wool
or other fibrous material is drawn from the combs c by ordinary
means commonly adopted in drawing wool off from wool combing
machines.
Having thus described the nature of our said Invention, and the
means of carrying the same into effect, we would have it understood
that we do not confine ourselves to the precise details herein shewn and
described, so long as the peculiar character of any part of our Invention
be retained; but what we claim is, the various improvements hercin
described in the processes of preparing and combing wool and other
fibrous materials.
In witness whereof, I, the said Samuel Cunliffe Lister, have here-
unto set my hand and seal, this Twenty-third day of July, in
the year of our Lord One thousand eight hundred and fifty-
two.
S. C. (L.s.) LISTER.

in the year of our Lord 1852, the aforesaid Samuel Cunliffe Lister
came before our said Lady the Queen in Her Chancery, and acknow-
ledged the Specification aforesaid, and all and every thing therein con-
tained and specified, in form above written. And also the Specification
aforesaid was stamped according to the tenor of the Statute made for
that purpose.
Enrolled the Second day of August, in the year of our Lord One

JAMES AMBLER, both of Manningham, in the Parish of Bradford, in
the County of York, Manufacturers.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
CUNLIFFE LISTER and GEORGE EDMOND DONISTHORPE, of Leeds, in the County
of York, Manufacturers, send greeting.
WHEREAS Letters Patent, bearing date and duly sealed at Westminster,
the Second day of February, One thousand eight hundred and fifty-two, were
granted to the said Samuel Cunliffe Lister and James Ambler for their Inven-
tion 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 Second day of August, One
thousand eight hundred and fifty-two: And whereas by certain Indentures,
bearing date the Twenty-second and Twenty-third days of November, One
thousand eight hundred and fifty-three, the said Letters Patent, and the exclu-
sive right and enjoyment of the Invention therein mentioned, and all the
benefits and advantages thereof became vested in us, the said Samuel Cunliffe
Lister and George Edmond Donisthorpe: And whereas, since the inrolling of
the said Specification, we have ascertained that certain improvements therein
described 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 reason aforesaid, to enter a Disclaimer of those parts of the said Specifica-
tion hereafter mentioned.

page_text: 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
parts of the said Specification commencing with the words "Our Invention
relates, First," down to and including the word "Thirdly," together with
Figures 1 and 2 of the Drawings thereby referred to. Also the part of the
said Specification commencing with the words "In place of the above," down
to and including the words "upon a comb in the usual way, to be afterwards
drawn off." Also the words "accumulated in successive layers upon the
detaching comb, which will then be removed to have the wool or other fibrous
material drawn off from time to time, or it may be" (and, to make sense of
this paragraph, we strike out the letters "nother" of the word another). Also
the part of the said Specification commencing with the words, "The fourth
part of our Invention," down to and including the word "fifthly."
And it has been objected to the said Specification that detaching portions of
wool or other 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 described in the said Specification are separately claimed as parts of the
said Invention. For which reasons we introduce, near the end of the said
Specification, the following Disclaimer, that is to say:-We disclaim as being
of our Invention the detaching of quantities of wool or other fibrous materials
by nipping apparatus. And we also disclaim as being of our Invention the
separate mechanical parts described in this our Specification.
And we delare that the Specification, altered as above mentioned, will be as
follows, that is to say :-
