"IMPROVEMENTS IN MACHINERY FOR CARDING FIBRES."

PROVISIONAL SPECIFICATION left by the said William Kitchin and

CARDING FIBRES."
This Invention consists in the application to machines for carding fibres of
certain appliances hereinafter described, whereby the supply of additional fibre to
the condensor carding & rubbers is secured so as to produce "knob" or fancy
yarn.
We employ a rotary drum which turns bobbins containing alubbings, the slubbing
passes to a pair of feed rollers which are stripped by a stripper mounted in
moveable bearings; the stripper is at intervals by crank, cam, or equivalent
mechanism brought into position to deliver the fibre to the doffer, from whence the
additional fibre so supplied along with the fibre on the doffer supplied in the
ordinary way is removed and passes to the rubbers, the additional fibre supplied
from the slubbing bobbins producing lump or "knobs " on the rubbed slubbing,
afterwards to be spun with yarn by ordinary apparatus. The slubbing on the
bobbins may be of various colors so as to produce "knobbed" yarns of fancy
colors.

passes
Atl is a frame or moveable bearing caused to reciprocate by means of the crank 2,
actuated by pulley 2* from the axis of the swift; at 3 is a rotary drum; 4 are
arms or horns which support the feed bobbins 5 containing slubbing 6; 7 and 8 are
a pair of feed rollers, the lower one 8 being fluted. As the slubbing
through the feed rollers 7, 8, it feeds the card roller 9 with slubbing fibre, and
when and so often as the said card roller 9 is brought by the action of the crank 2
into contact with the doffer 10 the latter takes a portion of the slubbing off the
card roller 9, and the slubbing 6 so deposited on or supplied to the doffer 10 is
afterwards stripped from the doffer along with the ordinary fibre thereon, whence
the latter and the slubbing fibre 6 pass to rubbers as usual, and the fibre supplied
from the slubbing 6 becomes incorporated with the ordinary fibre in the rubbing
or condensing, producing knobs or enlargement of varying colors on the finished
slubbing from which fancy knobbed yarn is spun.
The apparatus is geared as follows:-12 is a pulley driven from the shaft of the
doffer; on the axis is pinion 13 gearing with wheel 14, driving the drum 3, and
also the pinion 16 and plate wheel 17 on stud and adjustable carrier plate 18. The
wheel 17 gives motion to the pinion on axis of fluted roller 8; the plain roller 7
is driven by frictional contact with the fluted roller 8. At 20 is a roller or runner
on which the frame 1 is supported, and moves each time the crank 2 operates;
21, 22, 23, Figs. 3 and 4, drive the card roller 9. At Figure 5 is shown a view of
apparatus designed for feeding to the doffer a considerable length of slubbing fibre
so as to produce elongated knobs or elongated enlargements on the slubbing. At 24

page_text: is an endless belt lying close to or upon the cards of the doffer 10 so as to lay the
ends of the fibre down upon and into the cards; the frame 1 and gearing remain as
above, except the wheel 13, this we construct partly blank, that is to say, having
teeth partly around its periphery so as to give an intermittant rotation to the gear
wheels and to the card roller 9, the latter being partly stripped by the doffer 10
will shortly again make a partial rotation, supplying the doffer with another layer
of fibre; the crank 2 and reciprocating motion of the frame 1 will not be required
in this arrangement as the card roller remains in contact with the doffer. The
frame 1 and apparatus above described may be lifted off the bearing pulley or
runner 20 and off the crank 2, whereon the "condensor or main machine will be
used as ordinary and producing ordinary slubbings or condensor slubbing or
cardings. We prefer to apply the apparatus above described to the back doffer,
but it may be applied to a "carder" doffer.
"
Having thus fully described the nature and particulars of this our said
Invention, together with the manner in which the same is to be or may be
performed or carried into practical effect, we would have it understood that what
we claim as our Invention is,-
The construction, combination, and arrangement of apparatus for purpose
described, and substantially as illustrated by Drawings.
In witness whereof I, the said Thomas Kitchin, for and on behalf of myself
and the said William Kitchin, have hereunto set my hand and seal, this
Twelfth day of May, in the year of our Lord One thousand eight hundred
and eighty.
