PROVISIONAL SPECIFICATION.
Improvements in Machines for Combing Wool or Hair and similar
Fibrous Material.
I, JOSEPH COOPER, of Exchange Mills, Frederick Street, Bradford, in the
County of York, Camel's Hair Comber, de hereby declare the nature of this
invention to be as follows:-
This invention particularly relates to improvements in Platt's and other
machinery for combing wool or hair and similar fibrous material.
In order to obtain a proportion of superior noil after one or more slivers of
"top" have been drawn off I employ a suitable nip adapted to engage the short
fringe of noil left projecting and thereby draw off a good proportion of the longer
fibres of this in the form of a clean noil.
The nip I may employ consists of a horizontal circular nip plate revolving close
to the comb so that its edge extends beneath the fringe or fibres projecting
therefrom. Radial or approximately radial serrations are formed in the edge of
the face of this plate and a concentric annular groove is made in the plate cutting
through these serrations. A stationary curved press bar held down by spring
pressure is formed and mounted in such a way that the fringe or fibres passing
beneath is gripped between the press bar and groove and is drawn out. The said
serrations are of such a form that the fibres drawn out are carried round with the
nip plate until they pass from beneath the press bar and a plough piece (or pieces)
or its equivalent is provided to turn the fibres off the plate and deliver them in
any convenient way.

Improvements in Machines for Combing Wool or Hair and similar
Fibrous Material.
I, JOSEPH COOPER, of Exchange Mills, Frederick Street, Bradford, in the
County of York, Camel's Hair 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:-

[Di Q11

page_text: off I employ a suitable nip adapted to engage the short fringe of noil left pro-
jecting and thereby draw off a good proportion of the longer fibres of this in the
form of a clean noil.
The nip I prefer to employ consists of a horizontal circular nip plate revolving
close to the comb so that its edge extends beneath the fringe of fibres projecting
therefrom. Radial or approximately radial serrations are formed in the edge
of the face of this plate and a concentric annular groove is made in the plate
cutting through these serrations. A stationary curved press bar held down in
any convenient way by spring pressure is formed and mounted in such a way
that the fringe of fibres passing beneath is gripped between the press bar and
groove and is drawn out. The said serrations are of such a form that the fibres
drawn out are carried round with the nip plate until they pass from beneath the
press bar and a "plough" or its equivalent is provided to turn the fibres off the
plate and deliver them in any convenient way.
In the accompanying drawing Figure 1 represents a plan view of a comb circle
together with the drawing-off plate.
Figure 2, is a plan view of a portion of the same on a larger scale.
Figure 3, is a side elevation of the drawing off device.
Figure 4, is a radial section of a portion of the same through the press bar.
Figure 5, is an elevation looking from the centre of the comb circle of the
drawing off head.
Figure 6, is a view of a detail hereinafter referred to.
The nip plate 2 is placed immediately besides the comb 1 with its serrations 3
immediately below the fringe 4 of fibres left by the drawing off rollers 5. The
plate 2 is driven at the same peripheral speed as the comb and is carried by the
revolving shaft 6 mounted and rotated in any convenient way.
The arrows
indicate the direction of rotation of the comb and drawing off plate. The edge 7
of the stationary press bar 8 lies within the annular concentric groove 9 made
in the plate 2 and it is forced down with sufficient pressure to draw the pro-
jecting fringe 4" of fibres, passed beneath it by the serrations 3, out of the
comb. After passing from beneath the press bar the noil is "ploughed" off the
serrations in the plate or removed in any convenient way.
The bottom plate 14 of the drawing off head (Figure 5) is bolted to the steam
chest of the comb below the comb circle 1 and the two pillars 15 fixed to 14
carry the top. plate 16. A pendent bracket 17 is fixed to the underside of the
plate 16. Figure 6 represents a separate view of this bracket at right angles to
the view shown in Figure 5. A vertical rod 18 is mounted in bearings 19 and 20
in the bracket 17 and the press bar 8 is secured to its lower end. A spring 21
on the rod 18 compressed between the bearing 19 and the adjustable nut 22 is
provided to press the underside of the bar 8 down into the groove 9 with suffi-
cient pressure to draw off the fibres.
Two spring rods mounted in a similar way to 18 may be employed to hold and
press down the press bar 8.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is —
In a combing machine, the combination with the ordinary drawing off rollers,
of the noil drawing off device, substantially as herein shown and described and
illustrated in the accompanying drawings.
