page_text: LETTERS PATENT to Frank Fairbank and Joseph Robertshaw both of
Allerton in the West Riding of the County of York for an Invention
of "IMPROVEMENTS IN MACHINES FOR COMBING WOOL AND OTHER FIBROUS
SUBSTANCES
"
PROVISIONAL SPECIFICATION left by the said Frank Fairbank and Joseph
Robertshaw at the Office of the Commissioners of Patents on the 8th February
1883.
FRANK FAIRBANK and JOSEPH ROBERTSHAW both of Allerton in the West
Riding of the County of York IMPROVEMENTS IN MACHINES FOR COMBING WOOL
AND OTHER FIBROUS SUBSTANCES
This invention relates to certain improvements in Noble's and other combing
machines where two circular combs come near together or form a junction point,
and our object is to press the fibre between the teeth or pins of both combs
simultaneously at the above point or position in such a manner that the machine
can be run steadily with less noise and at an increased speed
In the case of a Noble's Combing machine we accomplish our object by mounting
immediately above one or both circles at each side of the machine a rotating
sectional brush so constructed that the bristles of each section enter and leave the
combs perpendicularly by which means the fibre is pressed between the teeth and
the bristles of the brush do not become "fish hooked" as is the case with rotating
brushes as ordinarily constructed when used for this purpose.
When thick slivers are being fed into the combs the fibres ima.diately before
being conducted under our improved brush may be flattened orc mpressed un der
one or more small rollers or other equivalent means
In conjunction with our improved brush revolving discs may be used to carry
our object into effect which may either have a separate motion or may be formed
as flanges on the boss carrying the brushes either Stationary or working press
plates may be used the latter being actuated so as to enter and leave the chambers
between the comb teeth at the requisite time. These press plates may be used in
lieu or in combination with the discs but in every case we use the rotating brush
which is built up in sections and each section made to swivel

Office on the 8th August 1883.
FRANK FAIRBANK and JOSEPH ROBERTSHAW both of Allerton in the West
Riding of the County of York IMPROVEMENTS IN MACHINES FOR COMBING WOOL
AND OTHER FIBROUS SUBSTANCES
This invention relates to certain improvements in "Noble's" and other combing
machines, where two circular combs come near together or form a junction point,
and our object is to press the fibre between the teeth or pins of both combs
simultaneously at the above named point or position in such a manner, that the
machine can be run steadily, with less noise, and at an increased rate of speed than
can be accomplished when fitted with brushes of the ordinary description.
The invention consists of mounting a rotating sectional brush over the comb-
circles at each side of the machine, where the teeth or pins of the comb circles
come together. Each section of the rotating brush acts vertically in its pressure
upon the fibre, pressing the same between the comb teeth, and in like manner is
withdrawn from the comb teeth, thus obviating the bristles of the brush being
"fish hooked," as is the case with ordinary rotating brushes.
The brush discs receive motion in any convenient manner from the uprights of
the machine; each section of the brush is fitted with an arm, which, on the disc
revolving, the end of each arm comes in contact with a fixed tappet, causing the
bristles of each section of the. brush, as they approach the comb teeth, to pass
vertically into the same.
In conjunction with our improved brush, revolving discs or press plates may be
used, for keeping the fibre between the teeth of the combs.
In order that our invention may be better understood, we will proceed to describe
the same more fully, by means of the accompanying drawings marked with letters
of reference.
Figure 1 represents a sectional elevation of one side of a Noble's combing
machine, shewing the position in which our improved apparatus is fixed. Figure 2
is a partial elevation of one side of a combing machine, shewing a front view of
our apparatus. Figure 3 is a diagram plan of the circular combs, with our
improved apparatus mounted on one side of the machine only, the other side being
a repitition. Figure 4 is a cross sectional detail of our brush, shewing the mode
of construction, and the method of mounting and driving of same. Figure 5 is a
back elevation of the brush, shewing the arms fitted to each section, and the
tappet for regulating the sections as required.
The sectional brush disc is indicated by the letter D, and is mounted on fixed
stud B; motion is transmitted to the said disc by means of vertical shaft C, and
worm C, actuating pinion mounted on spindle C2, to which is secured the disc D.
Around the said disc near to the circumference, we bore a number of holes in which
we fit the brush spindles E, and secure the same by the arms F. These arms
revolving along with the disc, come in contact with the stationary cam G, thereby
causing each section of the brush to assume a vertical position, as shewn by
Figure 5, the bristles entering perpendicularly, and pressing the fibre between the
teeth of the combs: and by virtue of the disc D revolving as described, and the
comb circles rotating, each section leaves the combs with the bristles of the brush
perpendicularly
In conjunction with our improved brush, revolving narrow flanges H may be
used to assist in carrying our object into effect, to press the fibre between the teeth

page_text: of the outer row in the large circle, and in order to accomplish this, we may extend
the spindle C beyond the face of the disc at J, and mount the flanges H on the
extended part, or they may be mounted apart from the spindle C³, as shewn in
drawings, but to the novelty of these flanges we make no claim whatever.
Figure 6 is a cross sectional detail of our improved brush, fitted up in a different
manner to the one before described; in place of the arms E being secured behind
the disc D, they form part of the spindle E, and are on the face side of the disc,
which is mounted on a fixed stud K, and receives motion in the same manner as
before described. In order to regulate the sections of the brush, we fix a tappet L
to the stud K, which on the rotation of the disc causes the sections to assume a
perpendicular position, as shewn by Figure 7 which is a front elevation of our
modified sectional brush shewing only a few of the brush sections mounted.
What we claim as our invention is:
The construction of sectional brushes substantially in the manner and for
the purpose as hereinbefore described and as illustrated by the accompanying
drawings
In Witness whereof I the said Frank Fairbank for and on behalf of myself and
the said Joseph Robertshaw have hereunto set my hand and seal this 6th day of
August in the year of our Lord One thousand eight hundred and eighty-three.
