the Invention of "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND
OTHER FIBROUS SUBSTANCES.”
Sealed the 24th May 1878, and dated the 11th December 1877.
PROVISIONAL SPECIFICATION left by the said Robert Beecroft and Frederick
Henry Wright at the Office of the Commissioners of Patents on the 11th
December 1877.
ROBERT BEECROFT, Combing Overlooker, and FREDERICK HENRY WRIGHT,
"IMPROVEMENTS IN
Manager of Albion Mills, Halifax, in the County of York.
MACHINERY FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
This Invention relates to further improvements in apparatus for combing wool
and other fibrous substances for which Letters Patent were granted to us, dated
the Fifteenth day of May, One thousand eight hundred and seventy-seven, No.
1897.
In carrying out the Invention, as described in the Specification of the said
Letters Patent, we have found that in employing a series of sectional or segment
combs, working in a circle, which are made to fall at the nearest point of the circle
or feed head of the inner or smaller circular comb, pressing the fibres coming from
the outside circular comb in the inner circular comb, the noils coming from the
fibres remained in the teeth or pins of the sectional or segment combs when lifting,
and to keep the teeth or pins clean we had to employ revolving brushes, causing
great wear and tear and great expense
The object of our present improvements is to obviate or remedy these defects and
expense, for which purpose we construct the falling segments with pressing metal
blades or knives instead of the teeth or pins or combs; the blades or knives are
made to fall at the nearest point of the circle or feed head of the inner or sinaller
circular comb, pressing the fibres coming from the outside circular comb in the inner

page_text: circular comb, keeping the nibs or noils behind the comb and leaving clean fringes
to pass through the drawing-off rollers in the usual way.
The blades or knives when entered between the teeth or pins of the small inner
circular comb support the teeth or pins in the process of drawing off, and give the
required pressure to hold the fibres and force the sliver in the small inner circular
comb with greater certainty, preventing the sliver rising in the teeth of the inner
circular comb when being drawn off.
By these means we produce an apparatus giving greater strength, less wear and
tear, and at considerably less cost, doing away with the teeth or pins of the falling
segments and with the revolving brushes.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Robert Beecroft and Frederick Henry Wright in the Great Seal
Patent Office on the 8th June 1878.
ROBERT BEECROFT, Combing Overlooker, and FREDERICK HENRY WRIGHT,
Manager of Albion Mills, Halifax, in the County of York. " IMPROVEMENTS IN
MACHINERY FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
The said Invention relates to further improvements in apparatus for combing
wool and other fibrous substances for which Letters Patent were granted to us,
dated the Fifteenth day of May, One thousand eight hundred and seventy-seven,
No. 1877.
In carrying out this Invention, as described in the said Specification of the said
Letters Patent, we have found in employing a series of sectional or seginental
combs, working in a circle, which are made to fall at the nearest point of the circle
or feed head of the inner or smaller circular comb, pressing the fibres coming from
the outside circular comb in the inner circular comb, that the noils coming from
the fibres remained in the teeth or pins of the sectional or segment combs when
lifting, and to keep the teeth or pins clean we had to employ revolving brushes,
causing great wear and tear and great expenso.
The object of our present improvements is to obviate or remedy these defects and
expense, for which purpose we construct the falling segments with pressing metal
blades or knives instead of the teeth, or pins, or combs; the blades or knives are
made to fall at the nearest point of the circle or feed head of the inner or smaller
circular comb, pressing the fibres coming from the outside circular comb in the
circular comb, keeping the nibs or noils behind the comb, and leaving clean fringes
to pass through the drawing-off rollers in the usual way.
The blades or knives, when they enter between the teeth or pins of the small
inner circular comb, support the teeth or pins in the process of drawing off, and
give the required pressure to hold the fibres and force the sliver in the small inner
circular comb with greater certainty, preventing the sliver rising in the teeth of
the inner circular comb when being drawn off.

page_text: By these means we produce an apparatus giving greater strength, less wear and
tear, and at considerably less cost, doing away with the teeth or pins of the failing
segments and with the revolving brushes.
But in order to enable our improvements to be better understood, we will proceed
to more particularly describe the same by reference to the accompanying Drawing,
in which,―
Figure 1 represents a sectional elevation of the seginental comb apparatus with
pressing knives or blades; Figure 2, front elevation; and Figure 3, plan of the
same.
Figure 4 represents a side elevation of a segment, with pressing metal blades or
knives, drawn full size; and Figure 5, front elevation of the same.
Similar letters of reference are used to represent similar parts.
A, pressing metal blades or knives fitted in falling segments B, which are made
to fall at the nearest point of the circle or foed head C of the inner or smaller
circular comb D, pressing the fibres coming from the outside circular comb E in the
inner circular comb D, keeping the nibs or noils behind the comb and leaving
clean fringes to pass through the drawing-off rollers in the usual way; the segments
are actuated by the studs F working on the up incline G, and travel on until the
studs come in contact with the down incline H and top guide I, when they
gradually drop until the flange J of the segment comes in contact with the collar K
of the standards L; the bottom of the segment and projecting plate M, in which
the blades or knives A are fixed, may be made lovel, as shewn in Figures 4 and 5,
the blades in this case are made less in height.
Having thus described our improvements, and the best means we are aquainted
with for carrying the same into effect, we would have it understood that we do
not confine ourselves to the precise details shewn and described, as they may be
varied without departing from the peculiar character of the Invention; but what
we do claim is, the construction and employment of segments fitted with metal
blades or knives, working in a circle, such segments being mado to fall at the
neurest point of the circle or feed head of the inner or smaller circular comb, giving
the required pressure to hold the fibres and force the sliver in the small inner
circular comb with great certainty, preventing the sliver rising in the teeth of the
inner circular comb when being drawn off, substantially as herein-before described,
and represented in the accompanying Drawing.
In witness whereof, I, the said Robert Beecroft, for and on behalf of myself
and the said Frederick Henry Wright, have hereunto set my hand and seal,
this Sixth day of June, in the year of our Lord One thousand eight hundred
and seventy-eight
