IMPROVEMENTS IN OR APPLICABLE TO MACHINERY FOR CARDING WOOL AND OTHER FIBRES
Year: 1879

page_text: LETTERS PATENT to Edward Fairburn, of Obelisk Grove, Cooper Bridge, near
Mirfield, in the County of York, Card Manufacturer, for the Invention of
"IMPROVEMENTS IN OR APPLICABLE TO MACHINERY FOR CARDING WOOL AND
OTHER FIBRES,"
Sealed the 15th June 1880, and dated the 17th December 1879.
PROVISIONAL SPECIFICATION left by the said Edward Fairburn at the
Office of the Commissioners of Patents on the 17th December 1879.
EDWARD FAIRBURN, of Obelisk Grove, Cooper Bridge, near Mirfield, in the
County of York, Card Manufacturer. “IMPROVEMENTS IN OR APPLICABLE TO
MACHINERY FOR CARDING WOOL AND OTHER FIBRES."
This Invention relates to the "fancy roller" employed in machinery for carding
and scribbling wool and other fibre, and the improvements consist in arranging
and constructing these rollers as follows:- Upon the surface of the wood roller I
attach the ordinary cards, leaving space between. In one or more of these spaces
I apply a comb or pins working in slots or grooves lengthwise of the roller and
communicating with the inside or outside of the said roller, the comb or pins being
so arranged that when required they will protrude or project through the slots or
grooves beyond the points of the fixed card teeth and operate upon the cylinders
when required. The distance that these comb teeth or pins project beyond the
points of the fixed card teeth is determined by the extent of the rising motion
which is given to them, and this may be effected by various combinations of
mechanism, such as eccentrics, cams, cranks, cones, or taper shafts and springs, so
arranged and operated upon as to cause the comb teeth to rise up and down the
said slots in the roller, and as the fixed card teeth wear down or become shorter
with using, the rising of the comb teeth can be regulated accordingly.
Instead of the rising and falling comb teeth being used in combination with
fixed card teeth they may be used alone, and project beyond the surface or
periphery of the wood roller to any extent required.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Edward Fairburn in the Great Seal Patent Office on the 17th June
1880.

This Invention relates to the fancy rollers employed in machinery for carding

page_text: and scribbling wool and other fibres; and the improvements consist in arranging
and constructing these rollers so that they may be used for two purposes, viz., the
roller may be used as an ordinary fancy, and when required the said rollers may
also be used to clean the card teeth on the cylinders. The apparatus employed
consists of combs placed longitudinally of the said roller, and capable of being
raised and lowered through slots formed in the said roller by means of eccentrics,
cams, cranks, cones, taper shafts and springs working within such roller.
In order that the Invention may be better understood I have given reference to
the accompanying Sheet of Drawings illustrative thereof. Fig. 1 is longitudinal
section of a fancy roller, A being the shaft by which it is turned. The end of the shaft
is bored out as at B to receive a screwed spindle C. Upon the shaft is placed a loose
boss D connected at top and bottom by rods E, which rods have bosses or cones El
placed at an oblique position thereon. The cones pass through the upright rods F,
at the top of which is placed the comb G for the purpose of cleaning the card teeth
on the cylinders. The comb frame may be round as shewn, or square, or other
shape. Fig. 2 is cross section taken through the line a, b, in Fig. 1; and Fig. 3 is
another cross section taken through the line c, d, also in Fig. 1. The Figs. 4 and 5
are details of the parts F, E, and E¹. When the roller is used as a "fancy" only,
none of the parts of my improvements are in use, but when the cards on the
cylinders require to be cleared the hand wheel H is turned, forcing the screw C
against the pin e, pushing the loose boss D on the main shaft A, a slot in the shaft
allowing the boss and pin to move endwise on the said shaft, such movement being
imparted to the rods E and oblique bosses El which passes through holes d,
lifting the upright rods F, and consequently the comb G. The height of this comb
can be regulated to the greatest nicety by the screw C, and when the comb G is
not required the hand wheel is turned in the opposite direction and the comb is
lowered, the spiral spring J pushing back the boss D upon the shaft A. Although
I have shewn two combs C, one or more may be employed, and for convenience
they are placed within the spaces left between the cards placed upon the surface of
the roller.
These combs can also be placed at any angle necessary to lift and deliver the
material under operation.
By the use of this Invention the stoppage of the machine for hand fettling of the
cards on the cylinders is dispensed with, and when preferred the cylinder can be
cleaned during the ordinary working of the machine.
Having thus described the nature and particulars of my Invention, and shewn
by Drawings how the same is to be performed and carried into practice, I would
have it understood that I do not confine myself to the exact details of the parts
herein shewn and described, as some of them may be varied without departing
from the peculiar features of the Invention, but what I claim is,-
Firstly. The use and employment of rising and falling combs or pins G for the
purpose substantially as herein shewn and described.
Secondly. The means or method for raising and lowering the combs or pins G
for the purpose substantially as herein shewn and described, or any mere modi-
fication thereof.
In witness whereof, I, the said Edward Fairburn, have hereunto set my hand
and seal, this Fifthteenth day of June, in the year of our Lord One thousand
eight hundred and sights
