I, ALBERT SMITH, of Field Head Mills, Bradford, in the County of York,
Spinner, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in "Nobles" and other rotary
combing machines, and has for its object, the partial and preparatory cleaning of
knotty matter from that part of the uncombed sliver which will lie immediately on
each side of the nearest point of contact of the two circles into which the sliver is
pressed to be combed by their recession.
As is well known, a comb circle" consists of several rows of pins at a convenient
distance from each other; and, in order to accomplish my object, I remove one or
more rows of pins at such a distance from the inside diameter of the comb circle
into which the uncombed sliver is fed or pressed, as shall correspond with the length
of the sliver drawn forward to be pressed into the second comb circle.
In the space thus effected I cause to be worked a short travelling comb, somewhat
similar to the one fully described in my specification dated December 22nd, 1880
No. 5369, which comb travelling on with and receding from the comb circle, partially
clears the uncombed sliver in the said, space; or, I may give the required motion
by means of an eccentric, on the top of which is attached the necessary incline to
give the vertical motion; the horizontal reciprocating motion being effected by the
eccentric.

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—
This invention relates to certain improvements in "Noble's" and other rotary
combing machines, and has for its object, the more effectual combing of the fibre
by the partial and preparatory cleaning of the knotty matter from that part of the
uncombed sliver which will lie immediately on each side of the nearest point of
contact of the two comb circles into which the sliver is pressed to be combed by their
recession and consists in the removal of one or more rows of pins at such a distance
from the inside diameter of the large comb circle, as shall correspond with the length
of feed or length of sliver to be drawn forward to be pressed into the second or small
comb circle. In the above-named space I work a comb operated so as to travel, for
some distance, at intervals with the large comb circle, and at the same time to recede
from the same and clear the uncombed sliver in the said space.
Fig. 1 on the accompanying drawings represents a diagram plan of one half of the
large circle, and one of the small comb-circles, with one set of drawing off rollers of
a rotary combing machine. Fig. 2 is an enlarged sectional detail through line a. b. :
Fig. 3 a plan of Fig. 2 through line C: Fig. 4 a plan of the comb slide shewing the
eccentric for operating the additional comb, and Fig. 5 a plan of the additional
comb.
The large and small circular combs are indicated by the letters E and F respectively,
the vertical comb teeth of the same being represented on portions of the combs only;
The rotary motion for operating the several parts of the combing machine is derived
from the vertical shafts S in the centre of each small circular comb F as hitherto, and
the drawing off rollers G and H placed on each side of the machine, are driven from
the respective shafts S, by the usual train of spur gearing represented by the dotted
lined circles.
On the spindle of one of the drawing off rollers G, 1 secure an additional spur
pinion J, which gears into another wheel secured on the eccentric shaft K, thereby
giving motion to the same.
The bracket L is secured to the steam chamber plate and supports the curved slide
plate M, one edge of which is set at a greater distance than the other from the inner cir-
cumference of the large circle. In this plate M is the slide bracket N, prepared with
an oblong hole N' for the reception of an eccentric P shown by detail Fig. 4: the
eccentric P being secured on shaft K, and by the same rotating, the bracket N is
caused to reciprocate in the curved slide plate M.
Secured to the eccentric centrally with shaft K, is a cam plate R, level at R' for
about one fourth of its circumference, the remainder being raised upon this cam
rests the end of angle-bar T, which is free to move vertically in bracket N: and to

page_text: the upper portion of bar T is secured my additional comb U having teeth projecting
into the space formed by the removal of teeth from the large circle and also teeth Z
close to the inner row on the said circle.
:
The fibre is fed and pressed into the comb circles in the usual and well known
manner common to all rotary combing machines, the fibre laying across the full
width and imbedded in the teeth of the comb circle E; and by the additional comb U
being operated in the manner described, any knotty or hard foreign matter there
may be in the fibre within the wide space in which the teeth of the additional
comb U work, the same is brought towards the narrow row of pins on the inside
diameter of the large circle; the comb U being operated by the eccentric P, travels
for some distance along with the large circle in the direction of the arrow, and at the
same time recedes from the comb circle E by the slide M being set as shewn by
Fig. 3 thereby combing the fibre in the space.
When the additional comb U is at the termination of its traverse in the direction
in which the large circle E is rotating, the incline of cam plate R raises the angle
bar T, and thereby the teeth of the additional comb U clear of the fibre, until the
bracket N and additional comb have been moved by the said eccentric to the extent
of their traverse in the opposite direction, when the cam plate allows the angle bar
and comb U to drop, and comb another portion of the fibre in the recess or space
between the pins.
The distance of the space from the inner diameter of the large circle E is such,
that, on the fibre being fed and pressed into the teeth of the two circles at W, tho
portion that has been combed or cleared by the additional comb U, is laid across tho
space between the large and small circles where nearest in contact; thus preventing
any knotty or hard foreign matter going along with the cleared fibre as is the case
when the comb teeth of the large circle are placed in the usual manner.
::
By placing the rows of pins at Z in additional comb U, they pass through and
comb out the beard" in the same manner as described in my specification No. 5369
A.D. 1880, by which the drawing off rollers H. are better enabled to nip hold and
draw off a second sliver.
Having now particularly described and ascertained the nature of this invention,
and in what manner the saine is to be performed, I declare that what I claim is:-
The large circle of a rotating combing machine prepared with a wide recess or
space between the pins in which is worked an additional coinb U operated substantially
in the manner and for the purpose described.
