and 6, Piccadilly, in the County of Middlesex, Patent Agent, for
the Invention of "IMPROVEMENTS IN MACHINES FOR CARDING WOOL,

PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonne-
ville at the Office of the Commissioners of Patents, with his Petition,
on the 17th March 1871.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent
5 Offices, 18, Chaussée d'Antin, Paris, in France, and 6, Piccadilly, in the
County of Middlesex, Patent Agent, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MACHINES FOR CARDING WOOL,

page_text: COTTON, SILK, AND OTHER FIBROUS MATERIALS," a communication to me from
Celestin Martin, a person resident at Verviers, in the Kingdom of
Belgium, Manufacturer, to be as follows:-
:-
This Invention relates to certain means for obtaining on the doffer of
machines for carding wool and other fibrous materials a net of wool or
other such materials of the same thickness throughout by the deposit on
every part of said doffer of successive casts of the material, such casts
being sufficiently repeated to obtain the thickness desired.
This Invention consists in imparting to the doffer for this purpose
besides its ordinary rotating movement a reciprocal motion by which it
is alternately brought near to and away from the main cylinder. This
double movement is obtained by means of a cog wheel keyed on to the
end of the doffer shaft, at whose lower end engages an endless screw of
which the axis receives a double rotating reciprocal motion by means
of a bevil wheel and an excentric keyed on to a shaft put into motion
by the motor of the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Adrien Bonneville in the Great Seal Patent
Office on the 15th September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18,
Chaussée d'Antin, Paris, in France, and 6, Piccadilly, in the County of
Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of March, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Adrien Bonneville, Her special
licence that I, the said Henry Adrien Bonneville, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Adrien
Bonneville, 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 MACHINES FOR CARDING WOOL, COTTON, SILK, AND OTHER
FIBROUS MATERIALS," a communication to me from Celestin Martin, a
person resident at Verviers, in the Kingdom of Belgium, Manufacturer,
the condition (amongst others) that I, the said Henry Adrien
Bonneville, 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 Henry Adrien Bonneville, 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.:
This Invention relates to certain means for obtaining on the doffer
of machines for carding wool and other fibrous materials a net or sheet
of wool (nappe ou toile de laine) or other such materials of the same
thickness throughout by arrangeing the main cylinder to deposit on
every part of the said doffer successive casts or sheets (couches) of the
material, such casts or sheets being sufficiently repeated to obtain the
thickness desired.
This Invention consists in imparting to the doffer for this purpose
besides its. ordinary rotating movement a reciprocal motion by which it
is alternatively, brought near to and away from the main cylinder. This
double movement. is obtained by means of a cog-wheel keyed on to the
end of the doffer shaft, at whose, lower part engages an endless screw,
of which the axis receives a double rotating reciprocal motion by means
of a bevel wheel and an eccentric keyed on a shaft put into motion by
the motive power of the machine.
This Invention is illustrated in the accompanying Drawings, in which
Fig. 1 is a side view of a portion of a carding machine, and Fig. 2 a top
view of the same.
A is the main cylinder; B is one of the workers of the machine;
The improvement
C, one of the clearers; D, the fly; E, the doffer.
that constitutes the said Invention consists in the working of this latter
cylinder. Thus besides the ordinary rotating and incessant movement,
as will be found in all doffers, as shewn in the direction of the arrow,
and which is imparted to the said doffer by means of the endless screw-F

page_text: working in the cog-wheel G, a backward motion is imparted to the said
doffer at the same time by the eccentric H keyed on the shaft I at every
turn of this latter. The backward motion is imparted to the doffer E
by the said endless screw F, because and besides the working of this
screw in the direction of the teeth of gearing G, the reciprocal backward
and forward motion is imparted to it by the eccentric H, which it
communicates to the shaft K. This latter shaft is moved in the
direction of the endless screw F by means of the gearing L on the
shaft I, which communicates the movement to the gearing M. N is
the comb for taking away the woollen sheet or sheets from the doffer E
on which they have been laid by the main cylinder A.
The result of thus working the doffer is that the sheet of wool
deposed by the main cylinder on the doffer and detached by the comb,
be formed of several successive nets or sheets that are placed one upon
the other on every part of the doffer, that is to say, that the shect of
wool be not formed of only one sheet on the doffer deposited by the
main cylinder, but by the deposit of the sheet of wool at the same time
in small quantities sufficiently repeated to obtain the same thickness,
which gives it the advantage of obtaining a sheet of wool much more
regular, that is to say, without interspaces, which are always seen in a
woollen sheet when manufactured by the ordinary process of one single
sheet.
Having thus described the said Invention, and the manner of per-
forming the same, I would have it understood that I do not confine
myself to the precise details herein indicated and represented in the
accompanying Drawings, as they may obviously be modified without
departing from the principle of the said Invention; but what I claim
and desire to secure by the said Letters Patent is,-
1stly. A double simultaneous rotating backward and forward motion
imparted to the doffer of machines for carding woollen and other fibrous
materials for the purpose of obtaining a sheet of wool composed of
several successive sheets of fibrous materials deposed on every portion
of the doffer by the main cylinder, as has been herein-before described
and shewn in the accompanying Drawings.
2ndly. A double simultaneous rotating backward and forward motion
as described, applied to machines for carding woollen and other fibrous.

page_text: 3rdly. A double simultaneous rotating backward and forward motion
as described, applied to machines for carding woollen and other fibrous
materials with doffers of one or two taking in furnished with collars.
4thly. A double simultaneous rotating backward and forward motion
as described applied to machines for carding woollen and other fibrous
materials with two doffers.
5thly. The reciprocal backward and forward motion of the doffer in
the machines for carding woollen and other fibrous materials as applied
and operating as herein described and shewn in the Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and seal, this Thirtieth day of August, in
the year of our Lord One thousand eight hundred and seventy-
one.
