page_text: LETTERS PATENT to Christopher Bradley, Machine Wool Comb Maker,
and John Campbell, Commission Wool Comber, both of Bradford,
in the County of York, for the Invention of "IMPROVEMENTS IN
POR COMPING WOOL AND ATHED FIRDDO "

Sealed the 6th August 1875, and dated the 9th February 1875.
PROVISIONAL SPECIFICATION left by the said Christopher Bradley
and John Campbell at the Office of the Commissioners of Patents,
with their Petition, on the 9th February 1875.
We, CHRISTOPHER BRADLEY, Machine Wool Comb Maker, and JOHN
5 CAMPBELL, Commission Wool Comber, both of Bradford, in the County
of York, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBRES," to be as
follows, that is to say :-
Our Invention relates to employing circular nips fitted inside a
O circular rotary comb acting on an inner smaller circular rotary comb,
and in employing circular racks made of homogeneous malleable iron in

page_text: machinery for combing wool and other fibres. For this purpose we
employ two or four circular nips fitted between an ordinary Noble's,
Lister's, or Rawson's comb, or other circular rotary comb, and an
inner smaller circular rotary comb, instead of employing circular nips
outside the large circular comb as heretofore. The circular nips bring
the tufts of wool or fibres from the outside feeding circular comb to
the inner smaller circular comb, leaving clean fringes of fibres inside the
circle of the teeth or pins, cleaning the noil ends of the tufts, and leaving
them on the outside of the teeth or pins; or we may use the inner
circular comb for feeding, and deliver with the outside or large circular
comb. The wool or fibres are drawn off by drawing-off rollers in the
ordinary way, and the fibres are kept pressed in the teeth or pins of the
comb by dabbing brushes.
Our circular racks are made of homogeneous malleable iron on which
are fitted brass circles having the teeth or pins forming the combs; these
brass circles are firmly secured to the malleable iron racks by means of
screws; by these means we save the expense of new racks when the brass
circles require to be changed, as heretofore they have been cast in brass
with the comb circles forming one piece.

SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Christopher Bradley and John Campbell in the
Great Seal Patent Office on the 9th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHRISTOPHER
BRADLEY, Machine Wool Comb Maker, and JOHN CAMPBELL, Com-
mission Wool Comber, both of Bradford in the County of York, send 2
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of February, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did for Herself, Her heirs and successors, 30
give and grant unto us, the said Christopher Bradley and John
Campbell, Her special license that we, the said Christopher Bradley
and John Campbell, our executors, administrators, and assigns, or such

page_text: others as we, the said Christopher Bradley and John Campbell, 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 "Iм-
PROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBRES," upon the
condition (amongst others) that we, the said Christopher Bradley and
John Campbell, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
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 Christopher Bradley and John
Campbell, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, reference:
being had to the Drawing hereto annexed and to the figures and letters
marked thereon, that is to say :-
The said Invention relates to employing circular nips fitted inside a
circular rotary comb acting on an inner smaller circular rotary comb,
and in employing circular racks made of homogeneous malleable iron in
machinery for combing wool and other fibres. For this purpose we
employ two or four circular nips fitted between an ordinary Noble's'
Lister's, or Rawson's comb, or other circular rotary comb, and an inner
smaller circular rotary comb instead of employing circular nips outside
the large circular comb as heretofore. The circular nips bring the tufts
of wool or fibres from the outside feeding circular comb to the inner
smaller circular comb, leaving clean fringes of fibres inside the circle of
the teeth or pins, cleansing the noil ends of the tufts, and leaving them
on the outside of the teeth or pins; or we may use the inner circular
comb for feeding and deliver with the outside or large circular comb.
The wool or fibres are drawn off by drawing-off rollers in the ordinary
way, and the fibres are kept pressed in the teeth or pins of the comb by
dabbing brushes.

page_text: Our circular racks are made of homogeneous malleable iron on which
we fit brass circles having the teeth or pins forming the combs, these
brass circles are firmly secured to the malleable iron racks by means of
screws; by these means we save the expense of new racks when the brass
circles require to be changed, as heretofore they have been cast in brass
with the comb circles forming one piece.

page_text: rotary comb is actuated by wheel gear S worked by the circular rack T,
or we may use a worm and worm wheel. The circular nips A. bring the
tufts of wool or fibres from the outside feeding comb C to the inner
circular comb B, leaving clean fringes inside the circle of the teeth U,
cleaning the noil ends of the tufts, and leaving them on the outside of
the teeth or pins, or we may use the inner comb B for feeding and
deliver them on the outside of the comb C. The wool or fibres are
drawn off by drawing-off rollers in the ordinary way, and the fibres are
kept pressed in the teeth or pins of the combs by dabbing brushes.
T, circular rack, made of homogeneous malleable iron, on which we fit a
brass circle V, having the teeth or pins C forming the comb; the brass
circle is firmly secured to the malleable iron rack T by means of screws.
The rack W of the smaller inner circular comb is made also of homo-
geneous malleable iron having the brass circle fitted in a similar
manner....
We also employ two or four circular nips provided with angular
combs X fitted on the hollow shafts L; the nips A hold the tufts or
fibres until the combs X strikes through the tufts, liberating them from
the nips; the tufts or fibres are then drawn off by the drawing-off rollers
Z, catching hold of them and drawing off a sliver in the usual manner.
The angular combs may be made in one circle or in sections or segment
combs.
Having thus described our improvements and the best means we are
acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shewn
and described, as these may be varied without departing from the
peculiar character of the Invention, but what we do claim is,-
Firstly. The construction and employment of circular nips fitted
inside a circular rotary comb acting on an inner smaller circular rotary
comb, substantially as described and represented in the accompanying
Drawing.
Secondly. The employment of angular combs for liberating the tufts
of wool or fibres from the nips, substantially as described and
represented in the accompanying Drawing.
Thirdly. The construction and employment of circular racks made of

page_text: homogeneous malleable iron in machinery for combing wool or other
fibres, substantially as herein-before described.
.
In witness whereof, I, the said Christopher Bradley, for myself
and the said John Campbell, have hereto set my hand and seal,
this Seventh day of August, in the year of our Lord One thousand 5
eight hundred and seventy-five.
Witness,
CHRISTOPHER BRADLEY. (L.S.)
