IMPROVEMENTS IN NOBLES COMBING MACHINES
Year: 1886

page_text: We, JOHN BAIRSTOW SHARP, of Prospect Mill, Bingley, in the County of York,
Spinner and Manufacturer, and SAMUEL METCALFE of the same place, Combing
Overlooker, do hereby declare the nature of this invention for IMPROVEMENTS IN
NOBLES COMBING MACHINES to be as follows:-
This invention relates to certain improvements in Nobles' combing machines and
has for its object the pressing of the wool or other fibre between the pins of the
large and small circular combs, by reciprocating brushes so arranged that the
surface of the brushes and the liability of the bristles "fish hooking" are greatly
reduced.
The above object is accomplished in the following manner:-The dabbing brushes
are actuated by any well known means, but instead of having them the usual
length, we make them about one fourth, sufficiently long to press the wool or other
fibre between the teeth of the two combs where they come together, and in order
to prevent the wool or other fibre rising above the points of the pins after it has
travelled beyond the brushes, we place a curved plate close to the combs in the
space where the two combs divide, or in lieu of the plate, two curved bars may be
used joined together at one end near to the two circles, and placed at such an
elevation that the fibre passes along the underside of the same where it is divided
by the two circles in the usual manner.

We, JOHN BAIRSTOW SHARP, of Prospect Mill, Bingley, in the County of York,
Spinner and Manufacturer, and SAMUEL METCALFE, of the same place, 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:-
This invention relates to certain improvements in "Nobles'" combing machines,
and has for its object the pressing of the wool or other fibre between the pins of
the large and small circular combs, by reciprocating brushes and plates so con-
structed, that the surface of the brushes and the liability of the bristles "fish
hooking" are greatly reduced and consists in making the surface of the dabbing,
brushes of such area as to press the fibre between the pins of the combs where they
come together, and by preventing the fibre rising above the points of the pins with
a curved plate, or bars, fixed in the space between the comb circles where the fibre
is divided, and which is partly covered by the dabbing brushes when made of the
ordinary length, for the purpose of keeping the fibre in the circles.
In order to more fully explain this invention in detail, we have appended
drawings illustrative thereof, in which Fig. 1 represents the elevation of one pillar
of a "Nobles" combing machine, the large and small circular combs placed.
horizontally and actuated in the usual manner being in section: Fig. 2 a plan
shewing the small comb circle and a portion of the large, with the pillar in section.
Fig. 3 is a section through line a. b. in Fig. 2, and Fig. 4 a side view of the plate
fitted between the two circles.
The pillar A, with the shaft B mounted at the top thereof, is fixed and the shaft
actuated in the ordinary manner, as are also the large and small circular combs C
and D. The necessary reciprocating motion to the arm E and dabbing brush F
attached thereto, may be imparted by any of the well known ways now in common
use: such as that shewn by the drawing, or by a crank on the end of the shaft B,
to which we make no claim as being part of this invention.
According to this invention, in lieu of making the dabbing brushes of such
length so as to extend over a portion of the space between the two comb circles C
and D, now occupied by the additional plate G, we make each brush F about one
fourth the usual length, sufficiently long to press the fibre between the teeth or
pins P of the large and small comb circles where they come together, and to clear
the point of the said plate G. By this arrangement, the fibre is pressed into or
between the teeth P to below the points thereof; and by the comb circles revolving
in the direction of the arrows, and the plate G being stationary with the point G¹
elevated, the fibre is compelled to pass under the said plate, by which it is kept
from rising and riding over the points of the teeth at the division of the comb
circles, thereby keeping all the short fibre and foreign matter between the teeth of
the two circles, the same as when longer brushes are used, the long fibre being
drawn off the circles by the usual rollers.
In addition to the plate G for keeping the fibre below the points of the pins P,
we place one or more narrow plates H and H' curved to fit in the spaces between

page_text: the pins P, by which the fibre is kept down for the full width of the comb: thus
Decessitating it having to pass between or through all the pins, and thereby to be
more thoroughly cleaned and combed.
It is well known that by reason of the comb circles revolving at the same time
as the dabbing brushes are pressing the fibre between the teeth or pins P, in a
short time the bristles are bent in the direction which the comb circles are
revolving, thereby reducing the efficiency of the brushes to press and keep the fibre.
below the points of the teeth or pins, whilst it is being drawn through the pins by
the seperation of the comb circles.
The plate G may be substituted by two curved bars connected together, and
fixed the same as plate G by bars J, the curved bars acting in the same manner as
the flanges, keeping the fibre below the points of the teeth or pins P.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of the dabbing brush F with the plate G or curved bars and
the curved plates H and H¹ all arranged substantially in the manner and for the
purpose as hereinbefore described.
The combination of the dabbing brush F with the plate G for the purpose
described.
