page_text: LETTERS PATENT to John Frederic Harrison, of Bradford, in the County of
York, Commission Wool Comber, for an Invention of "IMPROVEMENTS IN
COMBING WOOL AND OTHER FIBRES, AND IN THE MACHINERY THEREFOR."
PROVISIONAL SPECIFICATION left by the said John Frederic Harrison
at the Office of the Commissioners of Patents on the 24th September 1881.
JOHN FREDERIC HARRISON, of Bradford, in the County of York, Commission
Wool Comber. IMPROVEMENTS IN COMBING WOOL AND OTHER FIBRES, AND IN
"
THE MACHINERY THEREFOR."
This Invention relates to further improvements founded upon an Invention for
which I obtained Provisional Protection, No. 2009, dated 9th May 1881, the
present improvements, consisting in ao adapting a nip to the large circular comb
that by means of one pair of drawing off rollers practically the whole of the
combed tuft is seized and drawn into a sliver of top, no combed fringe being left as
hitherto on the inside of the large circular comb after the said rollers have drawn
the sliver, thereby obviating the nec ssity of employing an additional pair of
drawing off rollers, and consequently of drawing off two slivers as at present.
In carrying out the present improvements I alapt and fit to the comb a suitable
nipping apparatus, but preferably the circular revolving nip known as Bradley and
Campbell's nip, in such a position relatively to the large circular comb and the
drawing off rollers, and between the small circular comb and drawing off rollers,
that the whole of the combed tuft is seized by the revolving nip and withdrawn
from the pins of the comb to such a distance as to allow all the shorter fibres of
the tuft, as well as the longer fibres thereof, to be seized by the drawing off rollers
and drawn into a sliver of top, no fringe being left by the drawing off rollers as
hitherto to be subsequently drawn into a second sliver.
A fringe of short combed fibre similar to that left on the inside of the large
circle of an ordinary comb is also left on the outside of the small circular comb
after its drawing off rollers have drawn a sliver of top, which fringe, travelling
with the small circular comb, is drawn off as noil. This fringe I convert into top
by so placing the nipping apparatus herein before referred to that it shall seizo and
pull out to the necessary extent the tuft of combed fires projecting from the small
circular comb as in the case of the large circular comb, so as to allow the drawing
off rollers to seize and draw off into top the whole of the tuft of the small circular
comb.

by the said John Frederic Harrison in the Great Seal Patent Office on the
24th March 1882.
JOHN FREDERIC HARRISON, of Bradford, in the County of York, Commission
Wool Comber. "IMPROVEMENTS IN COMBING WOOL AND OTHER FIBRES, AND IN
THE MACHINERY THEREFOR."
This Invention relates to further improvements founded upon an Invention for
which Letters Patent were granted to me, No. 2009, dated the Ninth day of May,
One thousand eight hundred and eighty one, the present improvements consisting
in so adapting a nipping apparatus to the large circular comb that by means of one
pair of drawing-off rollers practically the whole of the combed tuft is seized and
drawn into a sliver of top, no combed fringe being left as hitherto on the inside
of the large circular comb after the said rollers have drawn the sliver, thereby
obviating the necessity of employing an additional pair of drawing off rollers, and
consequently of drawing off two slivers as at present.
In carrying out the present improvements I adapt and fit to the comb a suitable
nipping apparatus, but preferably the circular revolving nipping apparatus known
s Bradley and Campbell's nipping apparatus, in such a position relatively to the
large circular comb and the drawing off rollers, and between the small circular
comb and the drawing-off rollers, that the whole of the combed tuft is seized by
the revolving nipping apparatus and withdrawn from the pins of the comb to such
a distance as to allow all the shorter fibres of the tuft as well as the longer fibies
thereof to be seized by the drawing-off rollers and drawn into a sliver of top, no
fringe being left by the drawing-off rollers as hitherto to be subsequently drawn
into a second sliver.
A fringe of short combed fibre similar to that left on the inside of the large
circle of an ordinary comb is also left on the outside of the small circular comb
after its drawing-off rollers have drawn a sliver of top, which fringe, travelling
with the small circular comb, is drawn off as noil; but I place the nipping
apparatus hereinbefore referred to in such a position that it shall seize and pull out
to the necessary extent the tuft of combed fibres projecting from the small circular
comb, as in the case of the large circular comb, so as to allow the drawing-off
rollers to seize and draw-off into "top" the whole of the tuft of the small circular
comb, no fringe being left as hitherto to be further operated on or to be drawn off
ns noil.
In order to enable my Invention to be better understood, I will proceed to
describe the same by reference to the accompanying Drawing, in which Figure 1
represents a block plan of an ordinary "Noble's" comb with a nipping apparatus
adapted thereto for operating on the combed tuft of the large circle of the comb,
according to my Invention; Figure 2, a similar view shewing the nipping apparatus
adapted to the comb for operating on the combed tuft of both the large and small
circles of the comb; and Figure 3, a similar view shewing a separate nipping
apparatus adapted to the large and small circles respectively of the comb. Similar
letters in all the Figures represent similar parts.
In the arrangement shewn in Figure 1, A is the ordinary large circ'e of a
"Noble's" comb; B, the small circle; and C and D, the ordinary drawing-off
rollers of the large and small circles A and B respectively; E and Fare the
ordinary leather bands of the drawing-off rollers C and D. It should be noted
that in the following description the term tuft is applied to the projecting fibres
left after the large and small circles have separated; this term is used to distinguish

page_text: such fibres from those which are left in the ordinary combing machines after thè
drawing-off rollers used in such machines have drawn off the fibres they are able to
seize.
G represents a nipping apparatus, which may be similar to the circular revolving
nipping apparatus known as Bradley and Campbell's nipping apparatus, or of other
suitable construction. The said nipping apparatus is adapted and fitted to the
large circle A of the comb in the position shewn between the small circle B and
the drawing-off rollers C.
By this arrangement the whole of the combed tuft H which travels with the
large circle A, as usual, is when it reaches the point where the nipping apparatus G
and the pins of the large circle A come in contact, or nearly so, seized by the
revolving nipping apparatus G, and withdrawn or protruded from the pins of the
large circle of the comb A to such a distance as to allow all the shorter fibres of
the tuft, as well as the longer fibres thereof, when so elongated or protruded, as
shewn at I, to be seized by the ordinary drawing-off rollers C, and drawn into a
sliver of "top," no fringe being left by the drawing-off rollers as hitherto, to bo
Bubsequently drawn into a second sliver or otherwise.
In Figuro 2 the nipping apparatus G is shown adapted to the comb in a position
such that in addition to operating on the combed tuft H of tho large circle A,
in a manner similar to that herein before described and represented in Figure 1;
the said nipping apparatus also operates on the tuft J of combed fibre on the
outside of the small circle B of the comb in such a manner as to seize and pull out
the said tuft J and elongate or protrude it, as shewn at K, to the necessary extent
to allow the drawing-off rollers D to seize and draw off into a sliver or "top" the
whole of the said tuft so elongated, no fringe of short combed fibre being left as
usual on the outside of the small circle after its drawing off rollers D have drawn
a sliver, and which fringe M, as shewn in Figure 1, is usually drawn off, as and
with the noil L.
Although I have described and illustrated the use of one nipping apparatus for
operating either on the tuft of the large circle alone, or on the tufts of both the
large and small circles, it will be evident that a separate nipping apparatus may
be adapted to each circle, as illustrated in Figure 3, and which will be understood
without further description, similar letters being used in this Figure to represent
similar parts to those represented in Figures 1 and 2, with the addition of the
letter G, which represents a second nipping apparatus which is adapted to operate
on the tuft J of the small circle B.
Having now particularly described and ascertained the nature of the snid
Invention, and in what manner the same is to be performed and carried out in
practise, I wish it to be understood that what I claim is,-
Firstly. Elongating the combed tuft or tufts carried forward after the parting
of the large and small circles of a comb, such as a "Noble's" comb, before the said
tuft or tufts reaches or reach the ordinary drawing-off rollers, in such a manner
that the tuft or tufts so elongated is or are presented to the ordinary drawing-off
rollers in a condition to allow the whole of the tuft or tufts to be seized by such
drawing-off rollers and converted into a sliver or slivers of "top," no fringe being
left as hitherto, substantially by the means and in the manner hereinbefore
described.
Secondly. The combination, as herein described, of nipping apparatus with a
comb, such as a "Noble's" comb, so operating that the combed tuft or tufts
carried forward after the parting of the large and small circles of the comb is or
are partly drawn and elongated, and thereby presented in a condition for the
whole of it or them to be seized by the ordinary drawing-off rollers and converted
into a sliver or slivers of "top," no fringe being left as hitherto, substantially as
hereinbefore described and illustrated in Figures 1, 2, and 3 of the accompanying
Drawing.
Thirdly. The use of the nipping apparatus employed for operating on the combed
tuft or tufts carried forward after the parting of the large and small circles of a

page_text: "Noble's" comb, or other equivalent comb, in such a manner as to elongate or
protrude the said tuft or tufts, and allow the whole to be drawn into a sliver or
slivers of "top," as hereinbefore described.
In witness whereof, I, the said John Frederic Harrison, have hereto set my
hand and seal, this Twenty first day of March, in the year of our Lord
One thousand eight hundred and eighty two.
