CHARLES ALFRED BARLOW, of the Firm of Henry Bernoulli Barlow, of Man-
chester, in the County of Lancaster, Patent Agent. "IMPROVEMENTS IN CIRCULAR
COMBING MACHINES FOR COMBING COTTON, WOOL, SILK, AND OTHER FIBRE."
A communication from abroad by Monsieur Pierre Prosper Baudouin, père, of
Paris, France.
This Invention is applicable to those circular combing machines known as.
"Hubner's" machines.
The fibre is drawn from the comb by drawing rollers to which the requisite
pressure is applied, and it is carried between two endless aprons, on one of which
it rests in the form of an open web or fleece which has to be formed into a sliver
of sufficient strength to undergo the subsequent operations. The fibre is removed
from the lower apron by a blade or scraper moved to and fro by a cam or other-
wise, extending across the lower apron; at one side of the apron, near one end of
this blade, is a rotating trumpet mouth or funnel, into which the fibre is guided by
the blade, and by which a slight twist is given to it; from the trumpet mouth the
fibre in the form of a sliver is delivered by two leather covered rollers into a coiler;
there is an iron plate below the apron to support it where the scraper presses on it,
and to prevent any fibre passing under the blade. The fibre may be removed from
the apron by a radial scraper, or by a cylinder having longitudinal curved blades
or scrapers.
The feed and delivery are connected, so that the thickness of the

page_text: Bliver cannot vary when once the feed has heen regulated. For delivering the
waste a cylindrical comb or porcupine is used from which the waste is taken by a
brush, from which the waste is taken by a doffer covered with card fillet, from
which it is removed by an oscillating comb or stripper (which may be actuated by
an excentric) and deposited on an endless apron, on which the fly produced by the
machine also falls; this apron forms the bottom of a box made by the frame sides,
and it conveys the waste and fly to a suitable receptacle. The brush and doffer
are arranged and the cylinder is fitted so that it may be removed by the operator
for cleaning. I drive the "porcupine" from a wheel on the boss of a pinion on a
stud fitted on a slide concentric to the driving shaft from which it receives motion,
thus the speed of the "porcupine" (or cylinder comb) may be changed at will to
obtain combed fibre suitable to the number to be spun; this slide also allows the
band to be tightened without moving the wheel on the driving shaft out of gear
with the stud pinion.

CHARLES ALFRED BARLOW, of the Firin of Henry Bernoulli Barlow, of Man-
chester, in the County of Lancaster, Patent Agent. IMPROVEMENTS IN CIRCULAR
COMBING MACHINES FOR COMBING COTTON, WOOL, SILK, AND OTHER FIBRE."
A communication from abroad by Monsieur Pierre Prosper Baudouin, père, of
Paris, France.
This Invention is applicable to those circular combing machines known as
Hubner's machines.
And in order that this Invention may be fully understood, I will refer to the
accompanying Sheet of Drawings, in which
Fig. 1 is a plan of part of a combing machine to which this Invention is applied;
Fig. 2 is an elevation in section of the combing machine; Fig. 3 is an end view of
part of the machine; and Figs. 2, 4, 5, and 6, are detached views of parts of the
machine.
The fibre is fed to the machine from above as usual, and the long fibre is drawn
from the comb A by drawing rollers B, B, to which the requisite pressure is applied,
and it is carried between two endless aprons C and C'; it is detached from the
latter by the rollers D, D, on the axes of which are two small wheels gearing into
each other to ensure simultaneous rotation of the rollers; the fibre rests on the
apron C in the form of an open web or fleece which has to be formed into a sliver
of sufficient strength to undergo the subsequent operations. The fibre is removed
from the lower apron C by a blade or scraper e, e, e, fitted at the end of a horizontal
sliding bar E actuated by an eccentric F. This scraper extends across the apron
obliquely and presses lightly upon the surface of the apron; it is driven continuously
at a higher speed than the apron C, and it presses back all the fibres and lays thein
parallel with each other but obliquely to the apron; the scraper guides the fibre
into the rotating trumpet mouth or funnel G, by which a slight twist is given to
it; from the trumpet mouth G the fibre in the form of a sliver is delivered by two
leather covered rollers H into a coiler X, there is an iron plate a, a, a, below the
apron C to support it, and to ensure an even surface where the scraper presses on
it to prevent any fibre passing under the scraper. The fibre may be removed from
the apron by a radial scraper pivoted at a, see Fig. 4, to which a vibrating motion
is imparted by the eccentric F connected to the point b, causing it to describe an
arc, indicated by dotted lines to c, or by the vibrating scraper pivoted at D, see
Fig. 5, or by a rotating cylinder having longitudinal curved blades or scrapers, as
shown on Fig. 6.
The lower drawing roller B is driven from the driving shaft, and it communicates
motion by the helical wheels I, I, bevel wheels J, J, J, J, and spur wheels K, K,
K, K, to the delivering rollers H, H; and as the drawing rollers and delivery rollers
are thus connected by positive gearing, it follows that when the feed has been
regulated a sliver of uniform size will be delivered by the rollers H, H.
The driving shaft L by a belt on the pulley M communicates motion to the
pulley O fixed on the shaft N, N, on which is fixed the pulley P which drives by a
band running over guide pulleys U, U, the pulley R on the eccentric F which
actuates the scraper e, e, e. On the funnel G is a grooved rim or pulley, and it is
driven by a band from the cone pulley Q on the shaft N, N.
On Figs. 2 and 2ª is shown the improved arrangement of the cylindrical comb A",
the brush B, and the doffer C", by which arrangement the operative is enabled
to remove the cylinder easily for cleaning. The driving wheel V on the shaft L

page_text: gears into a wheel V₁ connected to the pulley J, both revolving on an adjustable
stud fitted in a slot g, h, concentric to the shaft L; by this means the stud wheel
may be readily moved and the strap tightened. A pulley of any suitable diameter
may be placed on the boss of the gear J" (driven by a strap from the pulley J)
which imparts motion to the cylindrical comb A" to increase or diminish the speed
according to the thickness of sliver required.
The cylindrical comb A" driven at a high speed combs the fibre that projects
from the dished wheel or turbine Y, Y. The shortest fibre and waste retained by.
the comb are removed from it by the brush B", which is driven at a surface speed
of about one-third quicker than the comb; the waste or noil is taken from the
brush B by the doffing cylinder C", which is covered with card fillet from which
the web of fibre is removed by the oscillating comb D.
Below the brush B" and the cylinders is the endless aprou E' which constitutes
the bottom of and closes the box formed by the frame F, F, and the plate G₁.
This apron runs over rollers H'; H',.and.it is driven from the shaft of the doffer
cylinder C by an endless chain and two sprocket wheels I, I. The fluff falls upon
this apron, and is covered near its exit by the web removed from the doffer
cylinder; the fluff and waste fall into a suitable receptacle placed below the driven.
roller H'.
The comb A¹ is driven at a uniform speed by the pulleys J, J, and the
wheels J, J. Motion is communicated to the brush B by the wheels K¹, K',
and to the doffing cylinder C" by the worm L, wheel M, and worm L' keyed on
the shaft N (see Fig. 2a), and the wheel O keyed on the shaft of the doffing
cylinder. The oscillating comb D is actuated by an eccentric connected to a stud R.
by the link P.
Having stated the nature of the said Invention, and described the manner
of performing the same, I would have it understood that I do not limit myself to
the details given, as they may be varied or modified, and what I claim is,―
1. The apparatus (or any modification of the same) for removing the fibres from
the apron C and laying them parallel with each other and at an angle to the
direction followed by the apron, and forming them into a sliver, substantially as
described and shown.
2. The improved arrangement of the cylindrical comb A", brush Bu, doffing
cylinder C, doffing comb D, and apron E, and the method of communicating
motion to the same, substantially as shown and described.
In witness whereof, I, the said Charles Alfred Barlow, have hereunto set
my hand and seal, this Tenth day of January, One thousand eight hundred
and eighty two.
CHARLES ALFRED BARLOW. (L.S.)
