PROVISIONAL SPECIFICATION left by the said Frederick Illingworth, John
Pickles, and George Carver at the Office of the Commissioners of Patents on
the 6th December 1878.
FREDERICK ILLINGWORTH, Wool Comber, JOHN PICKLES, Combing Manager, both
of Bradford, in the County of York, and GEORGE CARVER, Machine Maker, of
Cleckheaton, in the aforesaid County. "[MPROVEMENTS IN WORKING THE FLY
COMBS OR DOFFERS OF CARDING ENGINES."
Our Invention relates to giving the fly comb or doffing knife of a carding engine
an elliptical motion, so that the knife will strip the wool or other fibres operated on
from the doffer cylinder without any injury to the teeth of the clothing, preventing
the wool or other fibres being wrapped in a tight band, thereby spoiling or destroying
the clothing.
.
For this purpose we fit on the main frame of a carding engine brackets which
are fitted at each side and in front of the doffing cylinder; the tops of the brackets
are made with long bearings, through which passes a shaft extending across the
doffing cylinder.
On the end of the shaft and within the bearings are fitted eccentrics small in
diameter but long in width. Over the eccentrics and over the shaft of the doffing
cylinder is fitted a tubular shaft; in this tubular shaft work the eccentrics, and
when revolving give an elliptical motion to the tubular shaft and also to the fly
comb or doffer knife; this knife is fitted on small rods, which are fitted and fixed
Price 1

page_text: on the tubular shaft. On the end or ends of the bracket bearers are fitted and fixed
by set screws rings having projecting levers, and which project in front of the
carding engine; in the levers are passed the bolt ends of guide blocks, which are
secured to the levers by nuts; through the guide blocks work guide rods, which are
formed on rings, which rings fit on the tubular shaft, and are secured thereto by set
screws,
The tubular shaft when in operation is guided by the guide rods, which work in
and out of the guide blocks; the eccentrics are actuated by a pulley fitted on the
end of the eccentric shaft, the pulley being actuated by a strap or band from another
pulley fixed in any convenient part of the carding engine, or the shaft can be driven
by gear. The eccentrics in rotating in the tubular shaft cause the tubular shaft and
fly comb or doffer knife to have an elliptical motion, giving a receding motion on
the upward stroke to the fly comb from the teeth of the doffer cylinder, preventing
injury to the teeth and the forming of tight bands, also stripping or drawing the
wool or other fibres in a perfect manner on the downward stroke of the fly comb or
doffing knife.

of Bradford, in the County of York, and GEORGE CARVER, Machine Maker, of
Cleckheaton, in the aforesaid County. "IMPROVEMENTS IN WORKING THE FLY
COMBS OR DOFFERS OF CARDING ENGINES."
The said Invention relates to giving the fly comb or doffing knife of a carding
engine an elliptical motion, so that the knife will strip the wool or other fibres
operated on from the doffer cylinder without any injury to the teeth of the clothing,
preventing the wool or other fibres from being wrapped in a tight band, and thereby
spoiling or destroying the clothing.
For this purpose we fit on the main frame of a carding engine brackets which
are fitted at each side and in front of the doffing cylinder; the tops of the brackets
are made with long bearings, through which passes a shaft extending across the
doffing cylinder. On the ends of the shafts to the inside collars of the bearings are
fitted eccentrics small in diameter but large in width. Over the eccentrics and over
the shaft extending across the doffing cylinder is fitted a tubular shaft, in which
work the eccentrics, which in revolving give an elliptical motion to the tubular
shaft, and consequently to the fly comb or doffer knife; the knife is fitted on small
rods, which are fitted and fixed to the tubular shaft. On the inside collar of one of
the brackets is fitted and secured by a set screw a ring having a projecting lever,
in which is passed the bolt end of a guide which is secured to the projecting lever
by a nut; through the guide block works a guide rod formed on a ring, which is
secured by a set screw to the tubular shaft, but a ring having a projecting lever and
guide, and a ring with a guide rod secured to the tubular shaft can be fitted at each
end of the apparatus, and the projecting lever can be fitted with a small connecting
rod which is connected to a projecting lever formed on the ring secured to the
tubular shaft.
The tubular shaft when in operation is guided by the guide rod, which works in
and out of the guide or is guided by the small connecting rod; the inside shaft and
eccentrics are actuated by a pulley fitted to the eccentric shaft; the pulley is
actuated by a band or strap from another pulley fixed on a shaft, in any convenient
part of the carding engine, or the shaft can be driven by gear. The eccentrics in
rotating in the tubular shaft cause the tubular shaft and fly comb or doffer knife to
have an elliptical notion, giving a receding motion on the upward stroke to the
fly comb from the teeth of the doffer cylinder, preventing injury to the teeth and the
formation of tight bands, also stripping or drawing the wool or other fibres in a
perfect manner on the downward stroke of the fly comb or doffing knife.
But in order to enable our improvements to be better understood we will proceed
to describe the same by reference to the accompanying Drawing, in which Figure ]
represents a front elevation of our improved fly comb or doffing knife apparatus
fitted to a carding engine; Figure 2, side elevation; and Figure 3, plan of the
same.
Figure 4 represents a sectional front elevation of the eccentric drawn to an
enlarged scale with part of the tubular shaft and bracket; Figure 5; side view of
apparatus with section of eccentric and tubular shaft ;. Figure 6, front elevation of
the saine; Figure 7 represents a plan or top view of another method of guiding the
tubular shaft and Figure 8, side view of the same.
Similar letters of reference are used to represent similar parts.
A, frame work of a carding engine on which are fitted brackets B; the tops of
these brackets are made with long bearings C; the brackets are fitted in slides
made in bearing plates D, and the brackets are secured in position by set screws E;
through the bearings C passes a shaft F extending across the doffing cylinder, and

page_text: on the ends of the shaft are fitted eccentrics G, over which is fitted a tubular shaft
H; the eccentrics in revolving within the tubular shaft give an elliptical motion to
the tubular shaft, and consequently to the fly comb or doffer knife I, which is
secured to small rods J fixed to the tubular shaft. On the collar K of the bearing C
is secured a ring L, which is kept in position by a set screw; the ring is made with
a lever M, to which is secured by a bolt and nut one end of a link or small con-
necting rod N; the other end of the link is secured by a bolt and nut O to a lever
P formed on a ring Q, which is secured on the tubular shaft by a set screw R; the
screw screws through a boss S formed on the ring Q; the set screw presses a key T
against the outer surface of the tubular shaft, keeping the ring having the lever P
firmly secured in position; the tubular shaft and doffer knife is guided when in
operation by the link or small connecting rod N, which acts as a kind of parallel
motion to the elliptical motion of the tubular shaft. The shaft F and eccentrics G
are actuated by a pulley U fitted on the end of the shaft F, and the pulley U is
worked by a band V, which receives motion from a pulley W fitted on a shaft X of
the carding engine.
The eccentrics G rotating in the tubular shaft H cause the tubular shaft and the
fly comb or doffer knife I to have an elliptical motion, which gives a receding
motion on the upward stroke to the fly comb or doffer knife from the teeth of the
doffer cylinder Y, preventing injury to the teeth and the formation of tight bands,
also stripping or drawing the wool or other fibres in a perfect manner on the down-
ward stroke of the fly comb or doffing knife.
We may employ, instead of the small connecting rod or link N, a ring A¹ fitted
on the collar K of the bearing C; the ring is made with a lever B', in which is
secured a guide C¹, in which works a guide rod D' formed on a ring E¹, which is
secured to the tubular shaft by a set screw F¹. When the tubular shaft is in opera-
tion the guide rod D¹ works up and down or in and out of the guide C', guiding the
tubular shaft and doffer knife.
A guiding gear with a connecting rod or link or with a guide rod and guide, can
be fitted at each end of the apparatus.
Having thus described our improvements, and the best means we are acquainted
with for carrying the same into effect, we would have. it understood that we do
not confine ourselves to the precise details shewn and described, as they may be
varied without departing from the peculiar character of the Invention, but what we
do claim is,-
The giving to the fly comb or doffing knife of a carding engine an elliptical
motion by means of eccentrics working in a tubular shaft, so that the knife will
strip the wool or other fibres operated on from the doffer cylinder without causing
any injury to the teeth of the clothing, substantially as and for the purpose herein-
before described, and represented in the accompanying Drawing.
In witness whereof, I, the said Frederick Illingworth, for and on behalf of
myself and the said John Pickles and George Carver, have hereto set my
hand and seal, this Fifth day of June, in the year of our Lord One thousand
eight hundred and seventy nine.
