Patent Office, 24, Rue du Mont Thabor, Paris, in the Empire of France,
and 38, Porchester Terrace, Bayswater, in the County of Middlesex,
Patent Agent, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
CARDING AND SPINNING WOOL AND OTHER FIBROUS MATERIALS."-A com-
munication from Célestin Martin, residing at Pépinster, Verviers, in the
Kingdom of Belgium
Scaled the 2nd June 1868, and dated the 20th December 1867.
PROVISIONAL SPECIFICATION left by the said Henri Adrieu Bonneville
at the Office of the Commissiouers of Patents, with his Petition, on the
20th December 1867.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices,
24, Rue du Mont Thabor, Paris, in the Empire of France, and 38, Porchester
Terrace, Bayswater, in the County of Middlesex, Patent Agent, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR CARDING AND SPINNING WOOL AND OTHER FIBROUS MATERIALS," a communi-
cation from Célestin Martin, a person resident at Pépinster, Verviers, in the
Kingdom of Belgium, to be as follows:-
The improvements communicated to me relate to the formation of threads,
by means of two takers-in on the doffer covered all over with the fibrous
material to be spun, that is to say, without the separation being made on the
doffer at the moment the sheet of material is formed on the feed drum.
With

page_text: this view, on an iron bar fixed, in advance of the dropper, to the frame of the
machine, are fixed at equal intervals the extremities of thin steel blades which
are stretched well-nigh perpendicularly by little weights placed at their lower
ends; they are kept apart at the bottom by the divisions of a little cylinder.
These blades rest against the doffer on part of its circumference. Two combs
are placed in front of the doffer, one near the spot where the blades rest
against the doffer, the other at its upper part. The lower comb detaches the
little cloths of fibrous material placed in the intervals existing between the
blades, whilst the upper comb detaches the little cloths placed under the blades,
and which are discovered as the doffer rotates. The number of cloths or of
threads obtained equals in consequence that of the blades and the intervals
existing between them.
The accompanying Drawings represent a side view in Figure 1 and a partial
front view in Figure 2 of a machine with these improvements.
A is the iron bar; B, the blades; C, the doffer; D³, the lower comb; D",
the upper comb; E, the weights; F, the cylinder maintaining apart the blades;
G, the feed drum.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henri Adrien Bonneville in the Great Seal Patent Office on
the 5th June 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of December, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give' and grant unto me,
the said Henri Adrien Bonneville, Her special licence that I, the said Henri
Adrien Bonneville, my executors, administrators, and assigns, or such others
as I, the said Henri 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 MACHINERY FOR CARDING AND SPINNING WOOL

page_text: AND OTHER FIBROUS MATERIALS," a communication from Célestin Martin, a
person resident at Pépinster, Verviers, in the Kingdom of Belgium, upon the
condition (amongst others) that. I, the said Henri Adrien Bonneville, my
executors or administrators, by an instrument in writing under my, or their,
or one of their bands 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 Henri 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 :-
The improvements communicated to me relate to the formation of threads
by means of two takers-in on a doffer covered all over with the fibrous material
to be spun, that is to say, without the separation being made on the doffer at
the moment the sheet of material is formed on the feed drum. With this
view on an iron bar fixed in advance of the doffer to the frame of the machine
are fixed at equal intervals the extremities of thin steel blades which are
stretched well nigh perpendicularly by little weights placed at their lower ends;
they are kept apart at the bottom by the divisions of a little cylinder. These
blades rest against the doffer on part of its circumference. Two combs are
placed in front of the doffer, one near the spot where the blades rest against
the duffer, the other at its upper part. The lower comb detaches the little
cloths of fibrous material placed in the intervals existing between the blades,
whilst the upper comb detaches the little cloths placed under the blades, and
which are discovered as the doffer rotates. The number of cloths or of threads
obtained equals in consequence that of the blades and the intervals existing
between them.
Having thus summarily described the principle of the said improvements, I
will now more fully explain the same, reference being had to the accompany-
ing Drawings, Fig. 1 of which is a sectional side view of a carding machine
with a single doffer having two takers-in, to which the said improvements have
been applied, and Fig. 2 is a plan view of the same; like letters of reference
indicate corresponding parts in the Drawings.
A is a square bar connected by its extremities to the frame of the machine,
and on which are fixed the thin steel blades B. Theses blades rest against the
coffer C on a certain portion of its circumference and at the point on which
works the comb D'. Thes: blades B are kept in
a state of tension by little

page_text: weights E, and they are held at an equal distance apart from one another by
the little cylinder F having divisions. The comb D' is made after the same
manner as the upper comb D", that is to say, the dented blades are juxtaposed
in the entire length thereof; the said comb when in motion detaches the wool
which is in the intervals of the blades B, the number of these intervals being
the same as that of the blades, and the width of each interval being equal to
that of each blade it follows that one-half of the sheet of wool or fibrous
material on the doffer C is detached by cach comb, the comb Du detaching
the fibrous material which was under the blades B. Each comb therefore
detaches for the formation of the threads as many little sheets of fibrous
material as there are intervals or as many sheets of fibrous material as thero aro
steel blades B. The doffer C is covered all over with the fibrous material, that
is to say, there are no intervals in the combs, and the division of the sheet of
fibrous material, in. order to be made into threads, takes place at the comb D'
instead of taking place at the moment of the formation of the sheet by the
drum G.
Having thus described the nature of the said Invention, and the manner of
carrying the same into effect, I would have it to be clearly understood that I
do not intend to restrict myself to the exact details above given as the same
may be modified without departing from the principle of the said Iuvention,
but what I claim is,―
1°. The formation of threads on machines for carding and combing wool or
any other fibrous material having a single doffer without intervals in the combs
and without separation of the material whilst it is on the offer C by the big
drum G substantially as herein-before fully set forth and described.
2°. The division into threads, by means of the steel blades B, of a compact
sheet of fibrous material, which covers the whole of the doffer, that is to say,
without intervals in the covering sheet or without collars, at the moment the
said sheet of fibrous material detaches itself, whether this detachment be
operated by means of a comb or by means of a detaching cylinder, substantially
as herein-before fully set forth and described.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Twenty-ninth day of May, in the year of
our Lord Eighteen hundred and sixty-eight.
H. BONNEVILLE.
