Patents on the 30th May 1876.
ROBERT GOLDTHORP ACKROYD, Spinner and Manufacturer, ABRAHAM AMBLER,
Combing Manager, and JOHN BANKS, Foreman Mechanic, all of Birkenshaw, near
Leeds, in the County of York. "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
This Invention has reference to that class of combing machine known as
"Noble's," and our improvements apply,-
Firstly. To those machines in which intersecting or inverted combs are used in
connection with the small circles. Hitherto when such intersecting combs have
been used they have been caused to descend at the point of contact or nearest
approach of the large and small circles, so that the dabbing brush has had to be so
placed as to press or "dab" the wool into the outer comb only. By our improve-
ments we are enabled to use the "dabbing" brush in the usual manner, that is, to
act on both combs, and this we effect by two methods; the first of these consists in
lifting the intersecting combs above the "dabbing brush" and not allowing them
to descend until they have passed the saine, which is done by increasing the height
of the incline; the second method consists in mounting the segments of comb so
as to be capable of sliding in rests. The rests are raised and lowered vertically by
the usual incline, and by another incline or cam the segments are drawn within the
circle out of the way of the dabbing brush. By not causing the intersecting comb
to descend until the space between the two circles has become greater than at the
point where the wool is placed thereon we can vary the extent to which the said
comb overlaps the circle.

page_text: Secondly. Our improvements consist in the application of a "circle" cleaner,
which consists of a piece of leather, cloth, or other suitable substance curved to
about the outer radius of the circle and attached to the end of a rod to which an
elliptical motion is given by means of a crank and swivel stud in the usual manner.
The upward motion brings the cleaner in contact with the teeth of the circle and
lifts the short fibres projecting therefrom, which afterwards are entirely removed by
the usual noil lifters.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Robert Goldthorp Ackroyd, Abraham Ambler, and John Banks in the
Great Seal Patent Office on the 23rd November 1870.

This Invention has reference to that class of combing machine known as
"Noble's," and our improvements apply,-
Firstly. To those machines in which intersecting or inverted combs are used in
connection with the small circles. Hitherto when such intersecting combs have
been used they have been caused to descend at the point of contact or nearest

placed as to press or "dab" the wool into the outer comb only. By our improve-
ments we are enabled to use the "dabbing" brush in the usual manner, that is, to
act on both combs. We effect this by lifting the intersecting combs above the
“dabbing brush" and not allowing them to descend until they have passed the
saune, which is done by increasing the height of the incline. By not causing the
intersecting comb to descend until the space between the two circles has become
greater than at the point where the wool is placed thereon we can vary the extent
to which the said comb overlaps the circle.
Secondly. Our improvements consist in the application of a "circle" cleaner
which consists of a piece of leather, cloth, or other suitable substance curved to
about the outer radius of the circle and attached to the end of a rod to which au
elliptical or oval motion is given by means of a crank and swivel stud in the usual
inanner. The upward motion brings tho cleaner in contact with the teeth of the
circle and lifts the short fibres projecting therefrom, which afterwards are entirely
removed by the usual noil lifters.
In order that our Invention may be more fully understood we herein give
reference to an accompanying Sheet of Drawings marked with letters and figures.
Fig. 1 is a plan view of a small circle with intersecting combs and circle
cleaner attached, a portion of the large circle also being shewn; Fig. 2 is a side
elevation of same.
A are the intersecting combs supported on the upright pillars B, and which rise
and fall at the required time by the action of the cain or incline C. This incline is
made (as shown) sufficiently high to lift the comb above the "dabbing brush" by
which the operation of the latter is not interfered with. The comb is not allowed
to descend until the tangent point of the two circles is passed, and by thus
regulating the descent of the comb we can cause the upper coinb to descend outsido
the circumference of the lower one and effectually penetrate the portion of wool
which lays between the large and small circle at the tangent point or nearest point
of contact where the wool is fed on to the two combs.
Our circle cleaner consists of a piece of leather or other suitable substance a
curved to suit the outer circumference of the comb; this leather is attached to a
rod b passing through the swivel stude and connected with a crank wheel d, to

of the arrow.
In witness whereof, I, the said Robert Goldthorp Ackroyd, for and on behalf
of myself and the said Abraham Ambler and John Banks, have hereunto set
my hand and seal, this Eighteenth day of September, in the year of our
Lord One thousand eight hundred and seventy-six.
