Year: 1866

page_text: LETTERS PATENT to Joseph Jefferson, Cornelius Jefferson, Lazarus
Jefferson, Mordecai Jefferson, and John Greenway, of the Firm of
Joseph Jefferson and Company, all of Bradford, in the County of York,
Machine Makers and Iron Founders, for the Invention of "IMPROVE-
WRY MACHINERY FOR COURING WOOL OR OTHER FIBROUS MATERIALS."
Sealed the 12th October 1866, and dated the 18th April 1866.
PROVISIONAL SPECIFICATION left by the said Joseph Jefferson, Cor-
nelius Jefferson, Lazarus Jefferson, Mordecai Jefferson, and John
Greenway, at the Office of the Commissioners of Patents, with his
Petition, on the 13th April 1866.
We, JOSEPH JEFFERSON, CORNELIUS JEFFERSON, LAZARUS JEFFERSON, MOR-
DECAI JEFFERSON, and JOHN GREENWAY, of the Firm of Joseph Jefferson and
Company, all of Bradford, in the County of York, Machine Makers and Iron
Founders, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR COMBING WOOL OR OTHER FIBROUS MATERIALS," to be as
follows:-
In machinery for combing wool.or.other fibrous material when a fringe of
fibres is deposited upon a travelling.comb and is presented to drawing-off

page_text: rollers, after such drawing-off rollers have removed the projecting fringe a
certain proportion of the shorter fibres are left still projecting from the comb,
and our improvements relate to a means of drawing from the comb the fibres
so left by the drawing-off rollers in place of their being removed with the noil
as at present practised. For this purpose we employ a frictional rotating
nipping instrument constructed as described in the Specification of a Patent
granted to Charles Cowper, dated the 23rd day of February 1852 (No.
13,977). This nipping instrument is arranged to take hold of the fringe of
projecting fibres left by the drawing-off rollers close to the travelling comb,
and by its rotation combined with the movement of the travelling comb to
remove such projecting fibres from the comb. The fringe of fibres so removed
is presented by the farther movement or rotation of the nipping instrument to
another nipping or carrying instrument, which in its rotation removes the
fringe from the first-named nipping instrument and delivers it to another
rotating nipping or carrying instrument, by which it is carried to such a position
that it may be redeposited by means of a dabbing brush or other instrument
upon the travelling comb, the noil or short fibres left in the comb having been
removed, as is well understood. The fringe of fibres is so redeposited upon
the travelling comb as to project farther from such comb than when they were
previously presented to the drawing-off rollers, and after a fresh supply of
fibres have been deposited upon the travelling comb the fringe of short fibres
redeposited upon it will be presented to the drawing-off rollers with the new
supply of fibres so that they may be removed by the rollers with the
longer fibres; or the fringe of fibres redeposited upon the comb may be
drawn off in the form of a sliver by additional drawing-off rollers, as is well
understood.
In place of the arrangement previously described the nipping instrument
may be arranged to transfer the fringe of fibres it has drawn out to another
travelling comb, to be drawn therefrom in the form of a sliver.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Jefferson, Cornelius Jefferson, Lazarus Jefferson,
Mordecai Jefferson, and John Greenway in the Great Seal Patent Office
on the 13th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH.
JEFFERSON, CORNELIUS JEFFERSON, LAZARUS JEFFERSON, MORDECAI JEFFERSON,
and JOHN GREENWAY, of the Firm of Joseph Jefferson and Company, all of

page_text: Bradford, in the County of York, Machine Makers and Iron Founders, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Joseph Jefferson, Cornelius Jefferson, Lazarus Jefferson, Mordecai
Jefferson, and John Greenway, Her special licence that we, the said Joseph
Jefferson, Cornelius Jefferson, Lazarus Jefferson, Mordecai Jefferson, and
John Greenway, our executors, administrators, and assigns, or such others as
we, the said Joseph Jefferson, Cornelius Jefferson, Lazarus Jefferson, Mordecai
Jefferson, and John Greenway, 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 "IM-
PROVEMENTS IN MACHINERY FOR COMBING WOOL OR OTHER FIBROUS MATERIALS,"
upon the condition (amongst others) that we, the said Joseph Jefferson,.
Cornelius Jefferson, Lazarus Jefferson, Mordecai Jefferson, and John Green-
way, our executors or administrators, by an instrument in writing under our,
or their hands and seals, or under the band and seal of one of us or them,
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 I, the said Joseph Jefferson, on behalf of myself
and the said Cornelius Jefferson, Lazarus Jefferson, Mordecai Jefferson, and
John Greenway, 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, that is to say :-
In machinery for combing wool or other fibrous materials when a fringe of
fibres is deposited upon a travelling comb and is presented to drawing-off
rollers, after such drawing-off rollers have removed the projecting fringe a
certain proportion of the shorter fibres are left still projecting from the comb,
and our improvements relate to means of drawing from the comb the fibres so
left by the drawing-off rollers in place of their being removed with the noil as
at present practised. For this purpose we employ a frictional rotating
nipping instrument construct as described in the Specification of a Patent
granted to Charles Cowper, dated the 23rd day of February 1852 (No.

page_text: 13,977). This nipping instrument is arranged to take hold of the fringe
of projecting fibres left by the drawing-off rollers close to the travelling comb,
and by its rotation combined with the movement of the travelling comb to
remove such projecting fibres from the comb. The fringe of fibres so removed
is presented by the further movement of the nipping instrument to another
nipping or carrying instrument, which removes the fringe from the first-named
nipping instrument and delivers it to another nipping or carrying instrument,
by which it is carried to such a position that it may be redeposited by means
of a dabbing brush or other instrument upon the travelling comb, the noil or
short fibres left in the comb having been removed, as is well understood. The
fringe of fibres is so redeposited upon the travelling comb as to project
further from such comb than when they were previously presented to the
drawing-off rollers, and after a fresh supply of fibres have been deposited upon
the travelling comb the fringe of short fibres redeposited upon it will be
presented to the drawing-off rollers with the new supply of fibres, so that they
may be removed by the drawing-off rollers with the longer fibres; or the
fringe of fibres redeposited upon the comb may be drawn off in the form of a
sliver by additional drawing-off rollers, as is well understood.
In place of the arrangement previously described the nipping instrument
may be arranged to transfer the fringe of fibres it has drawn out to another
travelling comb, to be drawn therefrom in the form of a sliver, as is well
understood.
And in order that our Invention may be more clearly understood and
readily carried into practice, we will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a plan of so much of a machine for combing wool or other
fibrous materials as will enable us to describe the nature of our improvements
as applied thereto, and Figures 2 and 3 show sections of the working parts
taken at different points of their operation.
a is the rotating travelling comb upon which the fringe of fibres has been de-
posited and the projecting ends drawn therefrom in the form of a sliver by means
The further movement
of ordinary drawing-off rollers in the usual manner.
of the rotating comb a carries the projecting fringe of fibres (left in the comb
along with the noil by the drawing-off rollers) to the rotating frictional
nipper b, which is constructed in accordance with the principle described in
the Specification of a Patent granted to Charles Cowper, dated the 23rd day of
February 1852, No. 15,977, and also described in the Specification of a Patent

page_text: granted to Samuel Cunliffe Lister and James Warburton, dated December 13th.
1859, No. 2832. The rotating nipper 6 and stationary nipping surface b¹
take hold of the fringe of fibres projecting from the rotating comb.a, and by
the further rotation of the nipper b and comb a the nipper 6 removes such
projecting fringe of fibres, which by the further movement of the nipper is
carried and delivered to the rotating carrying instrument c. The carrying
instrument c takes the fringe of fibres under the stationary surface c¹ and
delivers the fringe of fibres to the rotating carrying instrument d, which takes
the fringe under the stationary surface d' and carries the fringe into such a
position over the teeth of the rotating travelling comb a that it can be re-
deposited upon such comb by means of a dabbing brush e or other depositing
instrument. The carrying instruments c and d we prefer to construct on the
frictional principle described in the Specification of the Patents before referred
to, and to so incline them relatively to the comb a and nipper 6 as to raise
the fringe into a suitable position to be redeposited in the comb a. During
the transfer of the fringe of fibres from the nipper b to the carrying instru-
ment d the noil left in the travelling comb a is removed in the usual manner
at the point f, and when the fringe of fibres is redeposited upon the comb a
it can either be carried forward with such comb a to be presented to the
drawing-off rollers with a fresh supply of fibres, so that the redeposited fringe
will be removed together with the fresh supply of fibres deposited upon the
comb a, or it may be removed from the rotating comb a separately in the
form of a sliver by means of drawing-off rollers, as shown at g.
Figure 4 shows an arrangement in which the nipping instrument b is caused
to transfer the fringe of fibres it has drawn out of the rotating comb a to
another travelling comb, to be drawn therefrom in the form of a sliver. a is
the rotating travelling comb carrying the fringe of fibres left therein with the
noil to the travelling frictional nipper b, as above described, which after
removing the fringe of fibres carries them into such a position that they may
be deposited into the teeth of the rotating travelling conib h by means of the
dabbing brush i or other depositing instrument. The fringe of fibres
deposited upon the comb h is carried by it to the drawing-off rollers k, which
removes the fringe of fibres from the comb h in the form of a sliver, the noil
left in the travelling comb a being removed at the point f in the ordinary
manner.
We would remark that we have not thought it necessary to show the
mechanism by which the various parts of the machine are actuated, as an
intelligent mechanic acquainted with this class of machinery will readily apply
the same, and the arrangement and construction of the machine may be

page_text: greatly varied without departing from the true character of our improve-
ments.
In witness whereof, I, the said Joseph Jefferson, have hereunto set
my hand and seal, this Ninth day of October, in the year of our Lord
1866
