Improvements in or appertaining to Lister's Combs for Preparing
Wool and like Fibres.
We, JOHN AMBLER, GEORGE AMBLER, JOHN AMBLER, Junior, SAM AMBLER,
all of Midland Mills, Bradford, in the County of York, Worsted Spinners, and
JONATHAN SHACKLETON, of the same address, Foreman Comber, do hereby
declare the nature of this invention to be as follows:-
It relates to improvements in or appertaining to Lister's combs for preparing
wool and like fibres, and has for its object the drawing-off of the fibre from the
circle' of such machines in a more perfect and efficient manner than has hereto-
fore been the case.
Hitherto, in this class of comb, there has been employed, in order to draw off
the wool or other fibre from the 'circle,' a vertical apron, travelling between a
pair of drawing off rollers, to pass the fibre into a revolving funnel or reducer,
and thence between a set of calender rollers, the fibre by these means being drawn.
off the circle and collected in sliver forin.
With this arrangement, many of the shorter lengths of the wool or fibre from
the short side of the 'circle,' do not pass into the revolving funnel, but are carried
downwards by the vertical apron.
These lengths of the fibre have therefore, to be collected and re-combed.
In order to overcome this defect, we twist the fibre, as it leaves the drawing off
rollers, into coil form, and to effect this we employ the usual form of drawing off
rollers, but instead of arranging the apron, passing between same, vertically, we
mount such apron in a horizontal position, or in a position approximately horizontal.
The wool or other fibre from the circle is thus drawn between the rollers and laid
on the apron. At right angles to the drawing off rollers, or in any other
convenient position, we fix an ordinary coiling apparatus, whereby the fibre,
immediately it has passed through the drawing off rollers, is twisted into a coil,
and drawn away by the said coiler.
By these means, the short lengths of fibre from the short side of the circle, are
coiled along with those from the long side, and moreover, by placing the apron
horizontally, the underside of the comb is made more accessible.

Improvements in or appertaining to Lister's Combs for Preparing

We, JOHN AMBLER, GEORGE AMBLER, JOHN AMBLER Junior, SAM AMBLER,
all of Midland Mills, Bradford, in the County of York, Worsted Spinners, and
JONATHAN SHACKLETON, of the same address, Foreman Comber, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
It relates to improvements in or appertaining to Lister's combs for preparing

page_text: wool and like fibres, and has for its object the drawing-off of the fibre from the
'circle' of such machines in a more perfect and efficient manner than has hereto-
fore been the case.
Hitherto, in this class of comb, there has been employed, in order to draw off
the wool or other fibre from the circle,' a vertical apron travelling between a pair
of drawing-off rollers to pass the fibre into a revolving funnel or reducer, and
thence between a set of calender rollers, the fibre by these means being drawn off
the circle' and collected in sliver form.
With this arrangement, many of the shorter lengths of the wool or fibre from
the short side of the 'circle' do not pass into the revolving funnel, but are carried
downwards by the vertical apron.
These lengths of the fibre have therefore to be collected and re-combed.
In order to overcome this defect, we twist the fibre, as it leaves the drawing-off
rollers, into coil form, and to effect this we employ the usual form of drawing-off
rollers, but instead of arranging the apron passing between same vertically, we
mount such apron in a horizontal position, or in a position approximately horizontal.
The wool or other fibre from the circle is thus drawn between the rollers and laid
on the apron.
At right angles to the drawing-off rollers, or in any other con-
venient position, we fix an ordinary coiling apparatus, whereby the fibre,
immediately it has passed through the drawing-off rollers, is twisted into a coil,
and drawn away by the said coiler.
By these means the short lengths of fibre from the short side of the circle are
coiled along with those from the long side, and moreover by placing the apron
horizontally the underside of the comb is made more accessible.
In order to fully explain our invention we append hereto a sheet of drawings
marked with letters of reference, wherein
Fig. 1 represents a plan view of the parts of a Lister's comb necessary to explain
this invention with our improvements added ;
Fig. 2 is a front view, and.
Fig. 3 is a side view of same.
In all figures like letters denote like parts.
The letter A designates the circle, and B the grooved drawing-off rollers
carried by suitable standards C, which are secured to the frame D of the
machine.
F is the rubber to prevent the lapping of the wool, and G is the leather apron.
Instead of placing this apron in a vertical position, as is the practice when the
wool is taken through a funnel and between calender rollers, we place it in a
horizontal position, or in a position approximately horizontal. For this purpose,
we carry the outer end of the apron around a roller carried in sliding bearings H
operated by screw and hand wheel, whereby the tightness of the apron can be
regulated. The drawing-off rollers B are driven in the usual manner by the
vertical shaft J through the bevel wheels J' and J. To one side of the comb, we
fix an ordinary wool-coiling machine K, the construction of which is well understood
to those conversant with the treatment of textile fabrics. This coiling machine is
driven from the comb, and preferably from the shaft J. For this purpose we fix
to the said shaft a wheel L which is made to gear with a wheel L₁, this latter
gearing with a wheel L' fixed to the vertical shaft of the coiling machine.
The fibre, as it leaves the rollers B, is taken to the coiling machine, as is shown
in the drawings by the letter M. A blast of air is blown on the fibre as it leaves
the drawing-off rollers, by means of the pipe N, to prevent loose pieces detaching
themselves.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
laim is
Firstly. In preparing wool and like fibres, the employment of a coiling machine
in combination with a Lister's comb, for the purpose of collecting the wool or

page_text: other fibre in coil, instead of sliver form, all arranged substantially in the mammer
as shown and described.
Secondly. In a Lister's wool comb, a horizontal apron working between the
drawing-off rollers and around a roller carried by movable bearings, together with
gearing for driving the coiling machine K, for the purpose herein set forth.
