page_text: LETTERS PATENT to Michael Henry, of Fleet Chambers, 68, Fleet
Street, in the City of London, Patent Agent, for the Invention of
"IMPROVEMENTS IN THE MODE OF AND MACHINERY OR APPARATUS FOR
PREPARING FIBROUS MATERIALS FOR BEING SPUN."-A communication
from abroad by Marie Philippe Auguste Pinel and Edouard Jules
Joseph Lecœur, both of 17, Boulevart Saint Martin, Paris, France.
Scaled the 1st August 1873, and dated the 20th February 1873.
PROVISIONAL SPECIFICATION left by the said Michael Henry at the
Office of the Commissioners of Patents, with his Petition, on the
20th February 1873.
I, MICHAEL HENRY, of Fleet Chambers, 68, Fleet Street, in the City
of London, Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MODE OF AND MACHINERY OR APPARATUS
FOR PREPARING FIBROUS MATERIALS FOR BEING SPUN" (communicated to me
from abroad by Maric Philippe Augusto Pincl and Edouard Jules
Joseph Lecœur, both of 17, Boulevart Saint Martin, Paris, France), to
be as follows:—

page_text: fibrous materials to instruments, appliances, or parts of apparatus used
in the operations of carding, combing, teasing, and preparing them for
being spun, by which operations they are laid parallel, freed from
impurities, and duly prepared for being spun, the impurities being driven
off by air, gas, or acriform currents, blasts, jets, or streams.
I proceed to describe certain improved apparatus in which air, gas, or
acriform fluid is used for the above described purposes. In this
improved apparatus a number of moveable bars, rods, or arms are
arranged in guide ways around a centre in a frame and move in a rotary
direction. Each bar with the next forms jaws or nippers for holding
the fibrous material to be treated. The interior of this arrangement
may be described as forming a sort of cylinder or cylindrical contrivance.
This portion of the apparatus is in connection and communicates by
means of air passages formed in the frame with a fan, blower, or
apparatus for injecting air. The air enters only in the opening between
the jaws at a part near rollers herein-after. described, the other spaces
being closed by a diaphragm.
Motion is given to the bars or jaws by toothed cam wheels against
which their axes bear. Each bar or jaw in turn is first met by the outer
periphery of the cams, and then drops into a notch between two teeth
therein, which draw it down, thus tending to close the space between it
and the immediately preceding jaw; and when the latter is drawn down
the first jaw is disengaged from the teeth of the cams and remains at
rest till another jaw acts on it, and so on.
A fleece of fibrous material is fed by fluted and pressure rollers to the 2
opening between cach pair of jaws in turn, the air blown or drawn in
through such opening directing and driving the fleece thereinto. When
the jaws are closed a cutter having to-and-fro motion slits the fleece in
an upward direction, and its free end is ready to be seized in the next
succeeding opening formed by the bars or jaws.
.

· The jaws carrying the fibrous material present it to a carding or
combing roller, wheel, or appliance which is cleared by a brush (revolving
ȧt greater velocity) from the impurities which the roller, wheel, or
appliance separates from the fibres and which are blown away by
currents of air from the fan. As the bars or jaws turn they abut against 3
another pair of cams the teeth of which are thicker than the space
between the axes of the jaws. The jaws open and these cams move the

page_text: bars which by their own gravity complete their revolution and come
again in position ready to be acted on by the first-named cams. A
similar arrangement consisting of guide ways with bars or jaws and
cams for working them takes the fibres at the end already acted on, and
air from the blower forces them into the opening between these jaws,
bars, or nippers which close a little before those acted on by the second-
named cams open, so that the fibres may not be free to be blown away.
Theso jaws also present their charge of fibre to a combing or carding
wheel with brush similar to the one above described.
The shafts of the two last-named sets of cams are in gear so that one
works the other. The fibres pass under a pair of rollers turning in a
reverse direction to that of the jaws and at greater peripheral speed,
theroby guiding the fibres in a different direction and bringing their end
in contact with a fluted roller working in a direction reverse to that of
these rollers whereby the fibres are guided right again and caught
between this fluted roller, and another roller exorting very slight
pressure. At that moment the cams open the jaws. The pressure
necessary for holding the fibres in the jaws when the fleece is separated
and carded is effected by a break on the cam shaft and regulated by a
weight adjustable on a lever.
The batches of fibrous material acted on and carried forward by the
fluted roller fall in layers on an inclined surface, where they are seized
between another fluted roller and pressure roller, and reconstituted into
a fleece which is drawn down through a funnel by a pair of rollers, which
also condense or cause the fibres to adhere to each other. The material
thence passes into a turning can or coiler.
Motion is taken from a driving shaft to work the various parts of the
machinery by means of gearing or suitable connections.
Several machines may be used in combination and the slivers
conducted from them (a number together) under a set of drawing rollers
to form a lap or coil, or be converted into a single sliver in a can
or coiler.
The following arrangement of machine may be used for carrying out
the Invention:-In this machine two hollow frame picces are connected
by air passages leading from a fan or blower worked by motion taken
from the driving shaft. The main driving shaft carries a wheel or
pulley working the carding rollers, the brushes, and one of the reversing

page_text: rollers through proper gearing. The tension of the driving shaft is
regulated by means of a screw adjusting the position of a pulley
(mounted on a threaded bearing) in a slot.
A cam plate or excentric imparts reciprocating motion to the cutter
carrier which is guided by a cross piece and by plates screwed to the 1
guide ways. One end of the cam shaft carries gearing for working one
of the fluted rollers which works the second fluted roller; a slight
drawing action regulated by a twin wheel overcomes the adherence of
the fibres and facilitates their separation.
The roller on which the cylinder carrying the fibre to be worked rests,
and which is separated from the first fluted roller by the inclined
surface over which the fleece travels, has a circumferential speed equal
to that of the fluted roller. The fibrous material roller is held between
side plates and a wheel is keyed to it worked by a pinion (fast to the
fluted roller) through intermediate gearing.
]
The second reversing roller has at one end a pinion worked by one on
the first reversing roller through an intermediate wheel. The second
roller and wheel may be raised in a backward direction turning or being
centred on the first roller so as to allow of the disengagement of the
pressure roller. Its distance from the jaws is regulated by the adjusting 2
screw.
A third fluted roller is worked by a wheel in connection with a bevel
wheel which drives a bevel wheel on an upright shaft, at the top of which
is a bevel pinion working a wheel connected with a pinion which actuates
a twin wheel. The pinion at back works a wheel on the fluted roller. 2
Its peripheral velocity is in relation to that of the feed (fluted) roller.
A fourth fluted roller is actuated by the third by a wheel keyed
thereon and intermediate gearing. Between the frame and this wheel is
a pinion working a wheel keyed on a roller working at the same rate as
the third fluted roller. A pinion works the roller which draws the sliver 3
through the shoot, and this roller works the can or coiler by intermediate
gearing.
Weighted pressure rollers are used. There are guards or shields over
the carding wheels and brushes. Doors or sight holes are provided for
inspecting the air passages. The slope of the inclined surface is 3
regulated by adjusting rods.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Michael Henry in the Great Seal Patent Office
on the 20th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MICHAEL
HENRY, of Fleet Chambers, 68, Fleet Stroet, in the City of London,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Michael Henry, Her special license that I,
the said Michael Henry, my executors, administrators, and assigns, or
such others as I, the said Michael Henry, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for “IMPROVEMENTS IN THE MODE OF and
MACHINERY OR APPARATUS FOR PREPARING FIBROUS MATERIALS FOR BEING SPụn,”
communicated to me from abroad by Marie Philippe Auguste Pinel
and Edouard Jules Joseph Lecœur, both of 17, Boulevart Saint Martin,
Paris, France, upon the condition (amongst others) that I, the said
Michael Henry, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
"
NOW KNOW YE, that I, the said Michael Henry, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, as communicated to me, reference being
had to the accompanying Drawings, and to the letters and figures marked
thereon, that is to say :-
According to this Invention currents, blasts, jets, or streams of air,
gas, or aeriform fluid are used for guiding and conveying or moving

page_text: fibrous material to instruments, appliances, or parts of apparatus used in
the operations of preparing fibrous materials for being spun, such as
carding, combing, and teasing them, by which operations they are laid
parallel, freed from impurities, and duly prepared for being spun, the
impurities being driven off by the air, gas, or aeriform currents, blasts,
jets, or streams.
I proceed to describe certain improved apparatus in which according
to this Invention air, gas, or aeriform fluid is used for the above-described
purposes. In this improved apparatus a number of moveable bars, rods,
or arms are arranged in guide ways around a centre in a frame, and move
in a rotary direction. Each bar, rod, or arm, with the next adjacent bar,
rod, or arm, forms jaws or nippers for holding the fibrous material to be
treated. The interior of this apparatus may be described as forming a
sort of cylinder or cylindrical contrivance. This portion of the apparatus
communicates by means of air passages formed in the frame, with a fan,
blower, or apparatus for injecting air so as to be in connection therewith.
The air enters only in the opening between the jaws at a part near
rollers herein-after described, the other spaces being closed by a
diaphragm.
"
Motion is given to the bars or jaws by toothed cam wheels, against
which the axes of the bars bear. Each bar or jaw in turn first meets the
outer periphery of the cams, and then drops into a notch between two
teeth therein, and is thereby drawn down, thus tending to close the space
between each bar or jaw and the immediately preceding bar or jaw; and
when the latter is drawn down the first jaw is disengaged from the teeth
of the cams, and remains at rest till another jaw acts on it, and so on.
'
A fleece of fibrous material is fed by fluted and pressure rollers to the
opening between each pair of jaws in turn, the air blown or drawn in
through such opening directing and driving the fleece thercinto. When
the jaws are closed a cutter having to-and-fro motion slits the flecce in
an upward direction, and its free end is ready to be seized in the next
succeeding opening formed by the bars or jaws..
The jaws carrying the fibrous material presented to a carding or
combing roller, wheel, or appliance, which is cleared by a brush
(revolving at a greater velocity than it) from the impurities which the 3
roller, wheel, or appliance separates from the fibres, and which are blown
away by currents of air from the fan. As the bars or jaws turn they abut

page_text: against another pair of cams the teeth of which are thicker than the
space between the axes of the jaws. The jaws open, and these cams
move the bars, which by their own gravity complete their revolution,
and come again in position ready to be acted on by the first-named cams.
A similar arrangement of apparatus, consisting of guide ways or slides,
with bars or jaws and cams for working them takes the fibres at the end
already acted on, and air from the blower forces them into the opening
between these jaws, bars, or nippers, which close a little time before
those acted on by the second-named cams opened, so that the fibres may
not be free or liable to be blown away. These jaws also present their
charge of fibrous material to a combing, carding, or teasing wheel, with
brush similar to the one above described.
The shafts of the two last-named sets of cams are connected or caused
to be in gear with each other, so that one shaft works the other. The
fibres pass under a pair of rollers turning in a reverse direction to that of
the jaws, and at greater peripheral speed, thereby guiding the fibres in
a different direction, and bringing their ends in contact with a fluted
roller working in a direction reverse to that of these rollers, whereby the
fibres are guided right again, and caught between the fluted roller and
another roller exerting very slight pressure. At that moment the cam's
open the jaws. The pressure necessary for holding the fibres in the
jaws when the fleece is separated and carded is effected by a break on
the cam shaft, and regulated by a weight adjustable on a lever.
.
The batches or clusters of fibrous material acted on and carried forward
by the fluted roller fall in layers on an inclined surface, where they are
seized between another fluted roller and pressure roller, and reconstituted
into a fleece which is drawn down through a funnel by a pair.of rollers
which also condense or cause the fibres to adhere to each other. The
material thence passes into a turning can or coiler.
Motion is taken from a driving shaft to work the various parts of the
machinery by means of gearing or suitable connections.
:
Several machines may be used in combination, and the slivers con
ducted from them (a number together) under a set of drawing rollers to
form a lap or coil, or be converted into a single sliver in a can or coiler..
The following arrangement of machine may be used for carrying out
the Invention:-In this machine two hollow frame pieces are connected
by air passages leading from a fan or blower worked by motion taken

from the driving shaft. The main driving shaft carries a wheel or pulley
working the carding rollers, the brushes, and one of the reversing rollers
⚫ through proper gearing. The tension of the driving shaft is regulated
by means of a screw adjusting the position of a pulley (mounted on
a threaded bearing) in a slot.
E
A cam plate or excentric imparts reciprocating motion to the cutter
carrier, which is guided by a cross piece and by plates screwed to the
guide ways. One end of the cam shaft carries gearing for working one
of the fluted rollers which works the second fluted roller.
A slight
drawing action regulated by a twin wheel overcomes the adherence of 1
the fibres, and facilitates their separation.
The roller on which the cylinder carrying the fibre to be worked rests,
and which is separated from the first fluted roller by the inclined surface
over which the flecce travels has a circumferential speed equal to that of
the fluted roller. The fibrous material roller is held between side plates, 1
and a wheel is keyed to it worked by a pinion (fast to the fluted roller)
through intermediate gearing.
The second reversing roller has at one side a pinion worked by one on
the first reversing roller through an intermediate wheel. The second
roller and wheel may be raised in a backward direction, turning or being 2
centred on the first roller, so as to allow of the disengagement of the
pressure roller. Its distance from the jaws is regulated by adjusting
screws.
A third fluted roller is worked by a wheel in connection with a bevel
wheel, which drives a bevel wheel on an upright shaft, at the top of which 2
is a bevel pinion working a wheel connected with a pinion which actuates
a twin wheel. The pinion at back works a wheel on the fluted roller.
Its peripheral velocity is in relation to that of the feed (fluted) roller.
A fourth fluted roller is actuated by the third by a wheel keyed
thereon and intermediate gearing. Between the frame and this wheel is 30
a pinion working a wheel keyed on a roller working at the same rate
as the third fluted roller. A pinion works the roller which draws the
sliver through the shoot, and this roller works the can or coiler by inter-
mediate gearing.
Weighted pressure rollers are used. There are guards or shields over 35

page_text: The slope of the inclined surface is regulated by adjusting rods.
In the accompanying Drawings Figure 1 is an clevation, Figure 2 is a
side view, and Figure 3 is a vertical section with some portions removed
for greater clearness. In all these Figures the same parts are indicated
by the same letters of reference.
The fibrous material to be prepared or operated upon by the machinery
or apparatus is fed in at the back of the machine, and the product or
fibrous material after having been prepared or operated on by the
apparatus is delivered at the front of the machine.
D is the framework in which there are fixed two slides or guide
ways L in which a number of bars 7 slide. These bars are furnished
with friction rollers which move in a rotary direction, and their axes aro
free to move adjustably in a direction parallel to the axis traversing the
centre of the guide way or slides.
•
The interior of this apparatus forms a sort of cylinder which is brought
into communication by passages formed in the framework with a fan or
air apparatus g. The drawing in of air can only be effected through
this cylinder through the spaces or intervals formed between the bars or
nippers at the part near the rollers marked I³, K³; the other intervals or
spaces are closed by the diaphragm D³. Motion is imparted to the bars
or nippers by two cams or excentric toothed wheels F³, both keyed on
the same shaft. The journals of the bars are supported in these cams.
In order that the arrangement of apparatus may be thoroughly under-
stood I propose to consider one of the bars or jaws separately. The bar
bears first against the periphery of the excentric or cam F³. It then
drops into the next tooth as the wheel turns in a downward direction.
The interval between the two immediately contiguous bars or jaws closes
because the preceding bar or jaw is closed, such preceding bar being
impelled in the same direction until the journals of the said bar have
completely escaped from the teeth of the cams or excentric whicels.
This bar or nipping appliance will remain at rest until a new bar presents
itself in its turn.
An arrangement of two fluted cylinders K², K³, and two pressure
cylinders I, J, brings a fleece or layer of cotton or other fibrous
substance to be dealt with to the mouth of the nippers into which the
draft guides it. When the nipping jaws are closed a blade i on a recipro-

page_text: cating carrier or frame passes up through the layer or fleece and slits it.
The free end enters into the fresh opening thus formed.
The nippers charged with the fibrous material pass in front of a
combing or carding roller A³. A rotary brush C³, which revolves with
greater velocity than this roller A³, frees it from the impuritics which it 5
has taken from the "worked" end of the fibres, and which are carried
away by an air pipe T supplied with air by the fan q through passages
in the frame D. The bars in their rotary motion meet with a pair of
cams or excentric wheels G³, each having nino teeth. Both cams are
keyed on one shaft, and impart to it rotary motion. The teeth being of 1
greater thickness than the spaces of the journals the bars at a certain
point of the periphery of the guide ways separate one from the other so
as to open. The cams each in its turn move the bars. The bars of
their own gravity complete their rotation, and each at the regulated
intervals bears against the cams F³. A similar and similarly actuated 1
arrangement in which there are two guide grooves I, bars, arms, or
jaws 1³, and cams or excentrics F* take the fibres by the ends operated
upon. The fan or air-blowing apparatus forces them to enter the opening
between the nippers or jaws thus freshly presented to them.
The nippers driven by the cams F' close just a little before the nippers 2
actuated by the cams G³ are opened, so that the fibres will not be free to
be driven away or removed by the fan or air-blowing apparatus.
The regulation or adjustment of the opening and closing of the nippers
and the length of the fibrous substance inserted between the nippers
evidently depends on the entire length of the fibrous material and the 2
quantity of waste anticipated.
The nippers guided by the slides or guide ways L³ pass in front of
the carding, combing, or preparing roller A³. The arrangement of the
brush G* and of the air pipe T³ is similar to the arrangement of like
parts above described.
The fibrous material engaged in the nippers after having been carded
or combed are disposed in a direction according to the radius of the
circular guide ways.
3
The opening between the jaws of the nippers produced by the teeth of
the excentric or cam wheels G' is formed when the fibres come near to 3
the angular part of the horizontal table or platform P'.
Thereupon a

page_text: bar or thin plate P³ passes behind the fibres and lays them flat on the
table P, and causes them to slido on its even surface for a portion of
their length. The bar or plate P³ receives to-and-fro movement by a
cam or excentric ¹ with differential motion. When the bar P³ has
reached the end of its stroke another bar or thin plate y¹ drops on to the :
end of the fibres lying on the table and keeps them in this position until
the bar P³ being raised by the action of the stud y' on the surface of the.
circular groove is drawn back and returns to bring and cause to slide
upon the table a new cluster or batch of fibres. The cam x' keyed on the
same shaft as the excentric 2¹ raises the bar or plate y', and allows it to
fall at the required interval, the various clusters, batches, hanks, or skeins,
are thus again arranged into a fleece, layer, or sheet, which is propelled
or sliden on the table or platform P³ until it meets a fluted roller j¹ and
a pressure roller c', between which it passes, so that the fibres are caused
to adhere together. The fibres thus obtain a certain adherence. The
fleece slides on the surface of the conduit , and thence passes into the
funnel or shoot w¹, being drawn therein by a pair of rollers d', e¹, from
which it issues in slivers (méche), in which condition it passes into a
coiling can.
For a series or set of similar machines a number of such slivers could
be led under an arrangement or drawing rollers, and thus form a coil,
fleece, or sliver.
In the machine shown in the Drawings there are two hollow frames D
connected together by the air circulation passages of the fan q, and by
air suction passages Tª, 113.
4
Motion is imparted to the main shaft by a driving shaft, by means of:
fast and loose pulleys A, A'. A fast pulley B, which works the pulley b¹.
of the fan or blower is in frictional gear with these pulleys. At the
other end of the main shaft is a wheel or pulley C working the wheels.
K, K', which actuate the carding rollers and the wheels L, L', which.
actuate the rotary brushes.
An endless band passes over a wheel P and over another wheel Y on a
screw-threaded boss. The tension of the band is regulated by means of a
screw / which adjusts the position of the wheel Y in the slide or slotted*
frame j. On the same side of the shaft is a pinion G which, through the
medium of the wheel H works the wheel I keyed on the shaft of the
cams F. A pinion on the main driving shaft near the wheel B works
a wheel E keyed on the shaft of the cams F³.
:

page_text: The pressure of the nippers which hold the fibres when the separation
of the fleece and of the carded material is effected is imparted by means
of a break J acting on the wheels J³, J', keyed on the shafts of the cams
G³, G. The pressure is regulated by means of nuts working on a rod J³
and actuating a spring J¹.
The stud plate or excentric plate / communicates a to-and-fro
reciprocating action to a small guide frame 9, on which is fixed
a separating blade or plate i which is guided by a cross bar a¹ and
two plates screwed on the guide ways L³.
On the shaft of the cams F³ is a pinion U which communicates motion ]
to a fluted roller K' by means of wheels V, W, Z. The number of teeth
of these wheels and pinions may be varied according to the length of
fibre to be worked, and the waste to be discharged therefrom. The
fluted roller K³ works the fluted roller K². A slight varying tension is
caused by means of the connected wheels Lº, I, between these two fluted 1
rollers to break the adhesion of the fibres and to facilitate the separation
of the fleece.
The roll of
The roller q', on which is the roll of fibrous material to be treated,
which is separated from the fluted roller K2 by the inclined surface m
turns with a velocity equal to that of the fluted roller K*. On this 2
roller q' is keyed a wheel C. This wheel is worked by pinions keyed on
the grooved roller K through intermediate gearing X, a, b.
fibrous material is held in place between the fluted jaws d. The fluted
roller is worked by the wheel E by means of the wheel a¹ connected
with a bevel wheel E' which works a like bevel wheel E³ on a vertical 2
shaft. At the upper end of this shaft a bevelled pinion E' works a liko
wheel D¹ connected with a spur pinion which works in gear with the
wheel Q. The pinion at back works the wheel O on the fluted roller j'.
The peripheral velocity varies according to the same ratio as that of the
feed fluted roller. Also the travel of the fibres on the platform P is 3
regulated according to the speed of this fluted feed roller. Against the
bearing of the fluted roller j¹ bears a pinion O' which actuates a wheel M
keyed on the axis of the roller d'. The pinion O' works a wheel M by
means of an intermediate gear wheel N; this roller has the same
peripheral speed as the fluted roller j'. The pinion ' works the pinion g¹ 3
keyed on the shaft of the roller a¹². The number of teeth of the pinions,
and the diameter of the rollers correspond with each other.
The coiling can is turned by the axis d¹ of a spur wheel in gear

page_text: with another wheel connected with a bevel pinion s' working a vertical
shaft t, which shaft actuates at its upper and lower ends the various
wheels supported in the parts of the framework z¹, z, w, and y.
