Year: 1858

page_text: LETTERS PATENT to Edward Fairburn, of Kirklees Mills, Mirfield, in tho
County of York, Card Manufacturer, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS EMPLOYED IN CARDING WOOL OR OTHER
FIBROUS SUBSTANCES."
Sealed the 9th November 1858, and dated the 11th May 1858.
PROVISIONAL SPECIFICATION left by the said Edward Fairburn at the
Office of the Commissioners of Patents, with his Petition, on the 11th
May 1858.
I, EDWARD FAIRBURN, of Kirklees Mills, Mirfield, in the County of York,.
Card Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN CARDING WOOL OR,
OTHER FIBROUS SUBSTANCES," to be as follows:-
This Invention relates chiefly to machinery known as the "single doffer.
condensers," but is in part applicable to other carding engines or machinery;
and the improvements consist in having the surface of the doffer cylinder
formed or constructed of rings of wood or other suitable material of any
required breadths or widths for rings of cards of corresponding widths to rest
upon. I place a flange of thin metal or other suitable material on each side
of the said rings, projecting to and even with the surface of the said cards,
leaving a small space betwixt the two flanges. I also place similar flanges.

page_text: betwixt rings of cards on the "stripping roller," projecting above or beyond
the surface of the cards, and so arranged that when the stripper and doffer
are brought together the flanges on the stripper will enter into the spaces
formed betwixt the flanges on the doffer, thus effectually separating the wool
or other fibrous substances on the surface of the doffer into strips of the
breadth of the card rings. I also apply a current or blast of atmospheric air
to the surface of the stripping roller, to prevent adhesion of the fibrous sub-
stances thereto by means of a perforated or slit pipe extending the length of
the stripper. This atmospheric current I also propose to apply to other
carding machines for a similar purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Fairburn in the Great Seal Patent Office on the
11th November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
FAIRBURN, of Kirklees Mills, Mirfield, in the County of York, Card
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward Fairburn, Her special licence that I, the said Edward Fairburn,
my executors, administrators, and assigns, or such others as I, the said Edward
Fairburn, my 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 "IMPROVEMENTS IN MACHINERY.
OR APPARATUS EMPLOYED IN CARDING WOOL OR OTHER FIBROUS SUBSTANCES," upon
the condition (amongst others) that I, the said Edward Fairburn, by an
instrument in writing under my hand and scal, 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 Edward Fairburn, do bereby declare the
nature of my said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
This Invention relates to machinery known as the "single doffer con-
denser," and the improvements consist in having the surface of the doffer
cylinder formed or constructed of rings of wood or other suitable material of
any required breadths or widths for rings of cards of corresponding widths to
rest upon, with a flange or shield of thin metal or other suitable material on
each side of the said rings, projecting to and even with the surface of the said
cards; leaving a small space betwixt the two flanges; also in having similar
flanges betwixt rings of cards on the stripping roller projecting above or
beyond the surface of the cards, and so arranged that when the stripper and
doffer are brought together the flanges on the stripper will enter into the
spaces formed betwixt the flanges or shields on the doffer, thus effectually
separating the wool or other fibrous substances on the surface of the dotter
into strips the breadth of the card rings, which are then conducted by grooved
rollers to the rubbers, where they are formed into slubbings or threads..
In order that my Invention may be clearly understood, I have given
reference to an accompanying Sheet of Drawings, illustrating the manner in
which the same is performed or carried into practice.
Fig. 1 is a sectional elevation of such portion of a condenser as my in-
provements refer to, drawn full size. A is a segmental part or portion of the
rim of an ordinary doffer cylinder, which is here shewn as formed or con-
structed of wood lags in the usual manner, but which may be constructed of
metal rings, on the outer surface of which are metallic rings B, placed side by
side the whole length or width of the doffer; C are rings of wire cards resting
thereon; D are metallic flanges betwixt the rings; E is the stripper, with
rings of cards on its surface, with metallic flanges placed betwixt, which
project beyond the surface of the cards; G is a roller with grooves formed at
suitable distances capable to admit the flanges F to enter and move therein;
II is a grooved roller over which the strips pass, which correspond with the
grooves on the roller G; I is the ordinary carrying roller; and J, J, the two
rubbing rollers. Fig. 2 is a side elevation of a part or portion of the stripper,
shewing the projecting flanges. Fig. 3 is a sectional plan of the rim of the
doffer and the stripper, shewing the form and construction thereof, and the
way or manner the flanges on the stripper enter into the spaces or betwixt
the shields on the doffer. Fig. 4 is an elevation of the rollers G and II,
shewing the form and construction of same. The arrows indicate the direction
of motion of the respective parts, and the dotted lines shew the course of the
wool or other fibre. It will readily be perceived that by means of these my

page_text: improvements the wool or other fibrous substances will be effectually divided
into strips, and by passing over the grooved roller H, will be narrowed or
partially formed into a thread or roving ready for the rubbers.
Having thus fully described the nature of my Invention, and the manner
in which the same is to be performed, I would have it distinctly understood
that I do not confine myself to the precise details of construction and arrange-
ment of the parts herein set forth; but I claim as my Invention the con-
struction and arrangement of the doffer and stripper of condensers, with rings
of cards and shields or flanges made of metal or other suitable material, and
also grooved rollers, as herein described and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, I, the said Edward Fairburn, have hereunto set my
hand and seal, this Ninth day of November, in the year of our Lord
One thousand eight hundred and fifty-eight.
