I, JONAS DENBY, of Oxenhope, near Keighley, in the County of York, Combing
Overlooker, do hereby declare the nature of this invention to be as follows, that
is to say:-
It relates to improvements applicable for use in connection with Noble's
combs used in the treatment of fibrous substances, and particularly to
means whereby the fibrous substances being treated are forced down into the
interstices intervening between the pins or teeth in said combs and consists in
constructing and producing such means or mechanism that the "dabbing
brushes" heretofore employed may be entirely dispensed with by the substitution
of better and more efficient devices.
To attain this object I mount between certain of the rows of pins or teeth in
the comb, plates or blades which will reach down from the top of such pins to
about their middle parts, while between the other rows of pins I mount, upon
the circle or body part carrying such pins, other plates, blades or
strips which
project upwardly to extend slightly above the middle parts of said pins, thus
these two series of plates, blades or strips will occupy alternate positions and the
course or path for the fibres beneath and above same will be somewhat of a
zig-zag form.
By the fibres being constrained to follow such a zig-zag path they are held
from being withdrawn at such parts from the large circular comb by the lesser
one by which means said lesser comb will only separate the shortest and least
useful fibres therefrom, while when the large comb has carried its fibrous sub-
stance clear of the retaining blades then the drawing-off rollers are enabled to
freely pull same and so comb it between the combs' teeth.
The blades which overhand the circular combs have slight lateral play allowed
them so that they may accommodate themselves to any irregularities in the
teeth of the comb.
To force the fibres down and under the overhanging blades I conduct a current
of air or blast of wind to strike against same at the right path of the motion to
force them to pass as desired, while I may employ rotary discs to straighten the
fibres and otherwise assist the wind blast. in its actions.

Improvements appertaining to Noble's Combs, used in the Treatment
of Fibrous Substances.
I, JONAS DENBY, of Oxenhope, near Keighley, in the County of York, Combing
Overlooker, 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, that is to say:
It relates to improvements applicable for use in connection with "Noble's
combs, used in the treatment of fibrous substances, and particularly to
means whereby the fibrous substances being treated are forced down into the
interstices intervening between the pins or teeth in said combs, and consists in
constructing and producing such means or mechanism that the "dabbing
brushes heretofore employed may be entirely dispensed with by the substitution
of better and more efficient devices.

In order that my said invention may be readily understood, I have hereunto
appended sheets of drawings illustrative thereof, to which, by figures and letters,
reference is made in the following description.
Fig. 1 is a plan view of a sufficient portion of a Noble's comb as will illustrate
the application thereto of my improvements.
Fig. 2 is a similar view to Fig. 1 but is drawn to an enlarged scale, and shows
my improvements on one side of the comb, the other side being identical.

Fig. 3 is a sectional elevation of parts shown by Fig. 2, but as seen in the
direction of the arrow x.
Fig. 4 is also a sectional view of parts shown by Fig. 2, but as seen in the
opposite direction to that indicated by the arrow a.
Fig. 5 is an elevation of parts illustrated by Fig: 2, and as seen in the
direction of the arrow y.
Figs. 6, 7 and 8 are elevation, sectional side elevation and sectional plan (on
line X-X of Fig. 7) respectively, of the delivery end of a blast or blow pipe
hereinafter described, and are drawn to a scale still larger than that of Figs. 2 to 5
inclusive.
Fig. 9 is a detail drawing, same scale as Figs. 2 to 5, of one of the plates or
blades mounted in the comb circles as hereinafter described.
Similar letters and figures of reference indicate similar parts throughout the
several views.
In accordance with my said invention I mount between the rows of pins 1 and
2 and those at 3 and 4 in the large comb circle a (which travels in the direction
indicated by the arrow w, Figs. 1 and 2), plates or blades c respectively which
reach down from the tops of said pins to about their middle parts, while between
the rows of pins 2 and 3 and those at 4 and 5, on the said circle a, I mount other
plates or blades d which may be varied in number and which project to extend
slightly above the middle parts of said pins, thus these two series of plates or
blades c and d will occupy alternate positions while the course or path for the
fibres beneath and above, same will be somewhat of a zig-zag form as shown by
broken lines, Fig. 4. In some cases blades may be dispensed with and only
those marked c employed. The blades are held stationary, while the circle u
upon which they are mounted travels beneath, near their ends d, being held by
the bracket which is fixed to the framework of the machine. The ends
slightly raised or have a projection on the upper side. I also preferably employ
a blade or strip e similar to those c and mount it to intervene between the pins
7 and 8 of the small circle b. It is obvious that the particular rows of pins or
teeth between which the different plates or blades are described as being placed
are

positions to one another.
By the fibres being constrained to follow a zig-zag path as above described,
they are held from being withdrawn at such parts from the large circle a by the
lesser circle so that said lesser comb will thus only separate the shortest and
least useful fibres therefrom, while when the large comb a has carried its fibrous
substances beyond and clear of the retaining blades c and d then the drawing-off
rollers are enabled to freely pull same in the usual and well known manner, so
as to comb it between the several rows of the said comb's teeth.
The blades cand e are mounted in their bearings f by their bolts or rods g, so
that they are enabled to have slight lateral play or side shake to allow them to
accomodate themselves to any irregularities that the rows of teeth in the comb
may have from their true circular paths. In many cases I find it advantageous to
serrate or notch the lower edge of the plates c and e

bearings and respectively, to strike against said fibres at that part of their
path of motion just before reaching the curved ends of the blades c and this blast
of wind I make to follow such a path that it will firstly extend in a thin current
across, or partly across, the rows of pins in both of the circles this part of the
current passing through the orifices h of the pipe h, while two other parts of the
current are conducted to strike between said rows of pins through the parts h³ h³
of the orifice in the same pipe, with sufficient force to force down the fibres as
desired. It will however readily be seen that the formation or construction of
the orifices of the pipe h may be somewhat altered to suit different
working conditions, such as the varied operations on different classes
of wools and fibres, that is to say, wool of short fibres, wool of
long fibres, mohair, alpacca, etc. The orifice of the pipe is arranged so that it
may be adjusted to direct its current of air to act upon the fibres before they are
submitted to the actions of the air from the pipe h, and bring them suitably dis-
posed into position to be acted upon by the succeeding air blast from the pipe h.
Any suitable fan, blower or air propelling mechanism may be employed for
producing the currents of air as described.
Rotary discs may be employed to straighten the fibres and so assist the wind.
blast in its actions when found necessary.
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:
:
1. The hereinbefore described improvement in the process of combing fibrous
substances consisting in feeding the fibres to the pins or teeth in the usual
manner, forcing them down into the interstices between the pins or teeth by
means of a suitable current or currents of air, and thus causing them to be
subjected to the combing action of the pins or teeth.
2. The improved apparatus for combing fibrous substances substantially as
described in which the fibres are forced into the interstices between the pins or
teeth by means of a suitable current or currents of air.
3. In a machine of the kind described for combing fibrous substances plates or
