Year: 1884

page_text: COMPLETE SPECIFICATION.
I, JOHN WALTER BRADLEY, of Thornton Road, Bradford, in the county of
York, Machine Wool Comb Maker, do hereby declare the nature of the said
invention for "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON, SILK,
FLAX AND OTHER FIBROUS SUBSTANCES" 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 further improvements on an invention for which
Letters Patent were granted to myself and Joseph Wood dated the thirtieth day
of June one thousand eight hundred and eighty-two Number 3088 the present
improvements having for object improved means whereby the feeding apparatus
described in the specification of the said former patent either alone or in com-
bination with further improvements hereinafter described can be fitted within the
large circle of and operate with an ordinary circular "Noble's" comb or any other
circular comb operating in a similar manner in its principal parts.
For this purpose, upon the table, and within the circle of an ordinary Noble's or
other circular comb, I fix in such manner that it can revolve, one of the circular
feeding apparatus described in the said former specification or with the improve-
ments hereinafter described the outer edge of the combing circle of such feeding
apparatus working sufficiently close to the inner surface of the large circular comb
as to allow both circular combs to revolve horizontally without friction at the
point where they come together. Both the feeding apparatus and the large
circular comb are caused to revolve by geared wheels driven from the main shaft
placed under the table of the combing machine. At the point where the two
circles come together, the sliver being operated upon is pressed into the teeth of
both the large circular comb, and the circular comb of the feeding apparatus by a
dabbing brush which is actuated by an eccentric working upon the main driving
shaft or by other convenient appliance.
The sliver after passing down through the inside of the top hoop of the feeding
apparatus is then carried over the outside of an adjustable hoop below it, which
hoop by being raised or lowered gives more or less nip to the sliver passing between
it and the top hoop.
The sliver after passing down through the inner side of the guiding hoops of the
feeding apparatus then passes down an incline, to the bottom of which incline

page_text: sliding traps are fitted, which traps work ensily in a vertical direction and by their
own weight press upon and hold the sliver which is under them and keep it at the
required tension. These traps are notched at their bottom and inside of their
lower part, such notches coming opposite to corresponding notches made at the
bottom portion of the inclines upon which they fall; the sliver passing between
these notched traps and the notched inclines is held firmly and prevented from
being dragged sideways by the revolving movement of the combing circle. The
incline does not revolve in a plane parallel with that in which the framework of
the feeding apparatus revolves but moves upon a bed plate which can be adjusted
by set screws or other similar devices at any convenient angle to the vertical axis
of the framework and by this means as the incline revolves with the traps pressing
down upon and holding the sliver the side of the incline which is at its highest
point passes round from the lower level to which it may be adjusted and under the
feed regulator such feed regulator draws down a portion of sliver of a length
proportionate to the distance in vertical height between the highest and lowest
points to which the incline is adjusted to reach during its revolution. The angle
at which the incline is adjusted therefore regulates the quantity of sliver pulled
down off the creels and afterwards delivered to tho comb at each revolution
according to the nature of the substance being combed.
Into the space between the traps and the circular comb of the feeding apparatus
the sliver to be combed is pressed down by an arc-shaped horizontal bar which is
bevilled off at the end where the sliver in its revolution with the feeding apparatus
first comes in contact with such har in order that the sliver may be thereby
gradually pressed down. This arc-shaped bar is called the "feed regulator" and
can be raised or depressed as required by means of nuts working upon the screwed
top of the standard supporting such bar.
Between the large circle of the comb and the combing circle of the feeding
apparatus is fixed a star or other similar revolving comb which is actuated by the
onward motion of the fibres passing under it in the space wherein the two circular
combs begin to separate.
This star, or other similar revolving comb is for the purpose of removing the nips,
noils or other impurities left in the partly combed fringe of sliver.
"
Drawing off rollers are applied to remove the sliver of combed wool in the
manner described in the specification of the said former patent and the noil passing
along with the comb is removed by knives in the usual manner.
In order to enable my improvements to be fully understood, I will proceed to
describo the same with reference to the accompanying drawings in which figure 1,
represents a sectional clevation of my improved feeding apparatus applied to an
ordinary Noble's or other circular combing machine and figure 2, represents the
-same in plan partly in section; figure 3, is a transverse sectional elevation.
Similar letters refer to similar parts in all the figures.
In figures 1, and 2, A, represents the sliver in balls supported by the arms B, of
the feeding apparatus; C, are the hoops of the framework of the feeding apparatus
inside which the sliver passes down but is carried outside the regulating hoop D,
which slides vertically upon the uprights of the framework.; the regulating hoop
being placed nearer to or further from the guiding hoop next above it thereby
causes more or less drag upon the sliver as may be required. E, is the inclined
plane down which the sliver passes and near the bottom of which the sliver is
nipped by the rising and falling traps F, which work vertically in guides H,
secured to the framowork of the feeding apparatus by stays G. The traps F, are
curved and form parts of the same circle as that which forms the base of the
incline E, and the bottom of the inside of these traps and the bottom of the inclino
are notched so as to insure a firmer grip of the sliver and to prevent such sliver
from being drawn to one side of the opening under the trap by the drag it receives
from the revolution of the comb.
J, is the circular comb of the feed apparatus, and K, is the circular comb of the
Nobles or other combing machine to which the before mentioned feeding apparatus

sliver, which has passed under the slides H, and under the feed regulator. O, is
pressed down into the teeth of both the revolving combs by the dabbing brush M,,
which is actuated by the eccentric N, fixed on the main driving shaft V, The feed
regulator O, is a curved bar which presses down the sliver in the space between the
incline E, and the teeth of the feeding apparatus J, and by raising or lowering this
curved bar by means of the check outs P, the pressure upon the sliver passing

wheels under the combing table in the usual manner and S; are similar rollers
taking away both slivers combined from both sets of drawing off rollers.
The framework of the-feeding apparatus and the incline are both driven by
pinions attached to the same shaft and working upon internal teeth and the two
circular comls are actuated by pinions T, receiving motion from intermediate
wheels from the driving shaft V.
:
In figuro. 3, which is a transverse sectional elevation of my improved feeding
apparatus, the bed plate Y, upon which revolves the incline E, is set at an angle
and adjusted in position by the set screw and check nuts Z, and as the incline
passes round with the feeding apparatus that portion of it which is for the time at
the side opposite to that on which the dabbing brush works, as it approaches and
comes opposite to the feed-regulator-bar hereinbefore mentioned, a portion of the
sliver is caught, and held down by such feed regulator, and as the incline revolves
to its highest level a certain length of sliver is pulled down from the creels, the
quantity pulled down at each revolution being regulated by the angle at which the
incline is adjusted, and by the pressure of the feed regulator. Two or more circular
combs having feeding apparatus working within their large circles may be fixed
upon the same table and be driven by the same shaft if desired.
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 :-
The application of a circular feeding apparatus having a circular revolving comb
to work within a Noble's or other similar circular comb in the manner and for the
-purpose-substantially-as-described-and-represented-in-the-accompanying-drawings-
