page_text: collecting the waste from the top rollers, and of certain movable cleaners
applied to the under side of the fluted rollers for the same purpose.
In applying our Invention to a drawing frame with four rows of
fluted rollers, we use two rollers covered with flannel which bear upon
and clean the four top rollers, these two rollers are connected by
adjustable links so as to be able to vary the distance between them, and
by toothed gearing or other equivalents. The under clearers or those
acted on the fluted rollers consist of four bars covered with flannel,
connected to a balance frame which is fixed to the lever of the front
stop motion, whereby the bars are traversed to and fro. Between the
said bars small rollers covered with flannel may be applied to collect
the dust.
The above details must be caried according to the number and
arrangement of the fluted and top rollers to be cleaned, and in machines
in which no traverse motion is provided we apply a crank or other
equivalent to move the under clearers to and fro.
SPECIFICATION in pursuance of the conditions of the Letters Patent;

next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Benjamin Dobson, Thomas
Thornley, and John Settle, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement.
(that is to say) :—
Our Invention consists in an improved mode of applying rollers
covered with flannel or other suitable substance for cleaning and
collecting the waste from the top rollers, and of certain movable cleaners.
applied to the under side of the fluted rollers. for the same purpose.
In applying our Invention to a drawing frame with four rows of
fluted rollers, we use two rollers covered with flannel, which bear upon
and clean the four top rollers; these two rollers are connected by
adjustable links, so as to be able to vary the distance between them,.
and by toothed gearing or other equivalents.. The under cleaners, or
those acting on the fluted rollers, consist of four bars covered with.
flannel connected to a balance frame, which is connected to the lever.
of the front stop motion, whereby the bars are traversed to and fro..
Between the said bars small rollers covered with flannel may be applied
to collect the dust.
The above details must be varied according to the number and:
arrangement of the fluted and top rollers to be cleaned, and in machines.
in which no traverse motion is provided we apply a crank or other
equivalent to move the under cleaners to and fro.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying

page_text: Sheet of Drawings, reference being had to the figures and letters
marked thereon.
Fig. 1 is a section and Fig. 2 an elevation of the roller beam and
drawing rollers of a drawing frame to which our improved cleaning
apparatus is applied. a is the roller beam; b, b, the stands; c, c, the
fluted rollers, and d, d, the top rollers; e is the link, which is connected
to the lever on the rocking shaft f¹, the link e being actuated by the
ordinary front stop motion; the parts above enumerated are all made
in the usual manner. The four top rollers d, d, are cleaned by the
rollers g, g³, the surfaces of which are covered with flannel; the rollers g
are turned round by the friction of the top rollers on which they rest,
and in order to increase the friction the rollers 9 are made of hard wood
or other heavy material, and the rollers g¹, which are made of sheet
metal or other light material, are turned by the mitre pinion h
on the axle of the rollers g gearing into the pinion ¹ which is fixed
on the shaft 2; to this shaft is fixed the worm h³ gearing into the
pinion on the axle of the rollers g¹. By this arrangement the
front cleaning rollers g¹ are driven at a slower surface speed than the
front top rollers d, and the inequality of the speeds causes the rollers g¹
to collect the flyings and dust more effectually than if the speeds were
equal. The axle of the rollers g revolves in the link i, and that of the
rollers in the link , and these two links are connected by the bolt **;
one of the links is provided with a slot to allow the distance between
the cleaning rollers to be varied according to the position of the top
rollers d. The fluted rollers c, c, are cleaned by the bars j, which are
covered with flannel. These bars are fixed to the balanced frame j¹,
this frame is jointed to the lever 1, which is hinged to the bracket e¹
fixed to the link e of the front stop motion; consequently, as this link e
is traversed to and fro by the stop motion the bars ; partake of the
same motion and thus strip the fibres from the under side of the fluted
rollers c, c, the fibres from the front and second rollers are collected in
the tin case ³, or they may be collected on rollers covered with flannel
placed between the bars j. The balance frame is pressed towards the
under side of the rollers c by the spring or other equivalent.
Fig. 3 is a section and Fig. 4 an elevation of the roller beam and
drawing rollers of an ordinary fly roving frame, to which our improve-
ments are applied; the parts marked a, b, c, d, g, g', j, j', and j³, are
similar to those marked with corresponding letters in Figs. 1 and 2.

page_text: In this and in other machines in which three top rollers d are employed
the centre top roller is stripped by both the cleaning rollers g and g¹,
and in order to compensate for the variations in the position of the top
rollers they revolve in the adjustable link i, 1ª, shewn in Fig. 5, the two
parts of which are united by the bolt. The cleaning roller g is made.
to revolve about twice as fast as the cleaning roller g¹ by the spur
pinion on the axle of the roller g gearing into the carrier pinion h³,
which gears into the pinion h* on the axle of the cleaning roller g¹, the
relative speed of the cleaning rollers can however be varied. The
carrier pinion h³ revolves on a stud fixed in a slot in the radial arm hª.
The traverse motion is imparted to the under cleaners ; by means of the
pinions c² on the back roller c and the pinion k, into which the pinion c¹
gears. A stud projects from the face of the pinion k, which takes into
a slot in the lever ², which is fixed to the end of the shaft l, to which
are fixed the levers ; the rods are jointed at one end to the levers /,
the other end is secured to the swing frame ³, consequently the cleaners
are traversed to and fro so long as the drawing rollers are kept in
motion. The swing frame is counterbalanced by the weights j* or other
equivalents.
Fig. 6 is a section and Fig. 7 a plan of part of a drawing frame
representing another mode of giving motion from one cleaning roller to
the other. In this arrangement the toothed chain m passes around
toothed pinions on the axles of the cleaning rollers g and g¹ and keeps
them at a uniform relative speed; the number of teeth in the pinions
can be varied at pleasure.
Figs. 8 and 9 represent our improved arrangement of cleaning the
top rollers of a single boss drawing frame, the bearings of the rollers g
and g¹ being in this instance united by the strap of metal n. The other
parts are similar to those shewn in Fig. 1.
Having thus stated the nature of our Invention, and described soveral
convenient modes of performing the same, we wish it to be understood
that we do not intend to limit ourselves to the details given, as the same
may be varied or modified according to the peculiar construction of the
machine to which it is applied, and what we claim is,―
First. The modes of connecting and driving the cleaning rollers
marked g, g', whereby they are driven at the proper relative speeds for
cleaning the top rollers,
;

page_text: Secondly. Making the under cleaners of fluted rollers in separate
parts and imparting a traversing motion to them.
'And lastly. Collecting the flyings of the under cleaners of fluted
rollers on rollers placed between the cleaners, as described, or in
receptacles as shewn in Figs. 1, 2, 3, and 4.
In witness whereof, I, the said Thomas Thornley, for myself and
on behalf of the within-named Benjamin Dobson and John Settle,
have hereto set my hand and seal, this Fourth day of January,
One thousand eight hundred and seventy-one.
