JOSEPH Ross, Machine Comb Maker, and CHARLES PEARSON, Engineer, both of

EMPLOYED IN MACHINERY FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
Our Invention refers to the employment of " dabbing brushes" constructed with
steel pins or wires fitted in the stocks of the brushes, instead of the bristles hereto-
fore employed, thereby producing an easy and effective pressure on the fibres, and
preventing great wear and tear of the brushes. For this purpose we construct, by
preference, the stock of wood, but we may employ metal stocks. The stocks are
nearly the same size and shape as the present stocks employed for bristles. In the
stocks we fit metal pins or wires, and by preference made of steel. The pins or
wires are centre pointed, and are fixed in the stocks at a slight angle leaning from
the centre of the stock, part to the left and part to the right. The metal pins or
wires when they enter between the teeth or pins of the combs when "dabbing
support the teeth or pins, and give the required pressure to hold the fibres, and
force the sliver in the combs with greater certainty, preventing the silver rising in
the teeth when being drawn off.
»
By these means we construct "dabbing brushes" having great strength, less wear
and tear, and producing better work than hitherto.

JOSEPH ROSS, Machine Comb Maker, and CHARLES PEARSON, Engineer, both of
Bradford, in the County of York. "IMPROVEMENTS IN DABBING BRUSHES
EMPLOYED IN MACHINERY FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES,"
The said Invention refers to the employment of "dabbing brushes" constructed
with steel pins or wires fitted in the stocks of the brushes, instead of the bristles
heretofore employed, thereby producing an easy and effective pressure on the fibres,
and preventing the ordinary great wear and tear of the brushes. For this purpose
we construct the stock of metal by preference, but we may employ wood stocks.
The stocks are nearly the same size and shape as the present stocks employed for
bristles. In the stock we fit metal pins or wires, by preference made of steel. The
pins or wires are made with rounded points, or are centre pointed, and are fixed in
the stocks at a slight angle leaning from the centre of the stock part to the left
and part to the right; or we construct the steel pins flat, and with rounded ends,
and made slightly tapering to the points. The metal pins or wires when they have
entered between the teeth or pins of the comb in " dabbing" support the teeth or
pins, and give the required pressure to hold the fibres, and force the sliver in the
combs with great certainty, preventing the sliver rising in the teeth when being
drawn off.
By these means we construct " dabbing brushes" having great strength with
less wear and tear, and producing better work.
But in order to enable our improvements to be better understood, we will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a front view of the improved "dabbing brush;" Figure 2, side view;
and Figure 3, plan of the same.
Similar letters of reference are used to represent similar parts.
A is the metal stock, made by preference of brass, in which are fitted round steel
pins or wires Band B', having rounded points C; the last row of the pins D are made
flat and of steel, and have also rounded points C, but flat pins can be fitted in any
portion of the stock A, or in any row of teeth or pins. The pins or wires are fitted
in the stock A at a slight angle, leaning from the centre or near the centre part, to
the left and part to the right. The pins fitted in the stock can all be flat steel pins
with rounded points; these flat steel pins are made slightly tapering from the stock
to the points. The rows of pins or wires enter between the teeth or pins of the
combs, and for "dabbing brushes" employed in "Noble's" combs the rows of pins B,
when dabbing, enter between the teeth of the outside circular comb, and the pins B'
when dabbing enter between the teeth of the small or inside circular comb. The
pins when dabbing support the teeth or pins of the combs, and give the required
pressure to hold the fibres, and force the sliver in the combs, with great certainty,
preventing the sliver rising in the teeth when the sliver is being drawn off. Holes
E are made in the stock to fix the brush to the dabbing slide F.
By these means we construct" dabbing brushes" having great strength, little
wear and tear, and producing better work.
Having thus described our improvements, and the best means we are acquainted
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 these may be varied
without departing from the peculiar character of the Invention; but what we do
claim is, the construction and employment of "dabbing brushes," having round or
flat steel pins made with rounded points, or centre pointed, either employed in

the said Charles Pearson, have heroto set my hand and seal, this Sixth day
of November, in the year of our Lord One thousand eight hundred and
seventy-eight.
