COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 28th May 1867, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
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 88, Porchester Terrace;
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY FOR WEAVING WOOL AND OTHER FIBROUS MATERIALS," a communi-
cation from Célestin Martin, a person resident at Pépinster, Verviers, in the
Kingdom of Belgium, Manufacturer, and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal Letters

page_text: Patent for the same, and made solenn declaration that it is a communi-
*cation.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the Invention, and the manner in
which the same is to be performed, reference being had to the accompanying
Drawings and to the letters marked thereon, that is to say:-
The improvements now communicated to me relate to those which formed
the object of a Patent granted to me on the Twenty-sixth day of September,
in the year of our Lord One thousand eight hundred and sixty-six, Number
2481, as a communication from Célestin Martin, "for improvements in
machinery for weaving wool and other fibrous materials."
These later improvements consist in substituting to the means employed for
forming the woollen sheets which make the thread a frame placed between
the feeding drum and the carding doffer, and on which are fixed at variable
intervals, and according to the thickness of the thread to be obtained, little
steel blades or steel or iron wire which prevent the deposit by the drum on
the carding doffer of the fibrous material, so that it passes only through the
intervals, more or less wide, left between the little blades or metal wire to form
the necessary sheet for the making of the thread; but these blades being
fixed and immoveable gave rise to certain difficulties, amongst others that of
choking up the intervals between the blades, and of not being able to cleanse
them. To do away with these inconveniences is the object of the present
improvements. They consist in rendering the said blades moveable by imparting
to them a regular up-and-down motion by means of a mechanism herein-after
described and represented in the accompanying Drawings, Figure 1 of which
is a longitudinal elevation of a wool carding machine with a single doffer, and
Figure 2 an end view of the machine showing the disposition and arrangement
of the blades, the carding doffer being removed.
The blades a are placed parallel on an inclined plane between the drum
and the carding doffer, and instead of being fixed on an immoveable frame as
before their upper ends are fixed in the circular grooves of a roller 6 which
correspond with the grooves of another roller b¹ serving to maintain the
parallelism of the blades; the lower ends of the said blades supported by
another roller c are furnished with little weights & which give the requisite
tension to the blades and serve to impart to these their downward motion. To
operate the upward motion of the blades the roller b in the circular grooves
of which they are partially wound receives a rotation movement by a band
chain e, one of the ends of which is fixed at the bottom of the grooved pulley f

page_text: keyed on the end of the roller b, whilst the other end is connected by a ring
and a pin e¹ to the big dented wheel g actuated by the little dented wheel g¹
which catches in with the endless screw keyed on the shaft i receiving its
motion from the motive power of the machine. When the pin e' has reached
the point by reason of the rotation of the wheel g the downward motion of
the blades gradually takes place, brought about by the tension produced by
the weights suspended at their lower extremities, and in consequence of the
relaxation of the chain resulting from its return movement upon itself during
the rotation of the wheel g. The cleansing and debarrassing of the blades
takes place during their up or down movement by means of the little rollers 1, 1ª,
furnished with cards which take away the fibrous material adhering to the
blades. The roller Z abandons the fibrous material to the roller m, which is
in juxtaposition, and the roller ¹ to the drum. A catch n falling into gear
with the ratchet teeth of the grooved pulley f prevents the blades from
suddenly unwinding should the connecting chain e so happen to break. The
catch is maintained disengaged from the teeth by the little pulley o on which
bears the chaine whilst it is stretched.
Having thus described the nature of the said improvements, and the manner
of carrying the same into effect, I claim in machinery for weaving wool and
other fibrous material the use of little steel blades or steel or iron wire placed
parallel at variable distances from each other between the feed drum and the
carding doffer, to which are imparted an alternative up-and-down movement,
whatever may be the mechanism employed to produce this movement, so as to
form in a regular manner the little sheets of wool or other material used in
the making of the thread on a throstle frame without any card collars on the
doffer, and without any sort of separation in the fibrous material neither on
entering nor inside the machine.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Twenty-second day of May, in the year
of our Lord One thousand eight hundred and sixty-seven.
H. BONNEVILLE. (L.S.)
