Foreign Patent Offices, 10, Sackville Street, Piccadilly, in the
County of Middlesex, and 24, Rue du Mont Thabor, Paris, in the
Empire of France, Patent Agent, for the Invention of "IMPROVE-
MENTS IN RIBBON LOOKS."-A communication from Christophe
Balay, residing at St. Etienne, in the Empire of France, aforesaid,
Manufacturer.
Sealed the 10th July 1868, and dated the 18th January 1868.
PROVISIONAL SPECIFICATION left by the said Henri Adrien
Bonneville at the Office of the Commissioners of Patents, with
his Petition, on the 18th January 1868.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent
Offices, 10, Sackville Street, Piccadilly, in the County of Middlesex,
and 24, Rue du Mont Thabor, Paris, in the Empire of France, Patent
Agent, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN RIBBON LOOMS," a communication from Christophe Balay, a person
resident at St. Etienne, in the Empire of France, aforesaid, Manufacturer,
to be as follows:-
These improvements relate to the manufacture and the cutting out
mechanically and simultaneously on bar looms of several pieces of

page_text: terry ribbon velvet in as perfect a manner as on the low heald loom,
with which a single piece can alone be manufactured. Three essential
conditions are necessary to obtain this result-the passage of the
cutting needles to the same side, the prop of the piece at the weaving
point, and a cording allowing the nap to be tied by four bottom strokes
with only two needles. To this effect on the foremost cross piece
of the loom a sliding rod for cach needle is set, actuated with a to-and-
fro movement according to the axis of the foremost cross piece obtained
by a treadle and a counterweight. On cach sliding rod and for each
piece of ribbon is fixed a support on which slides a guide supporting
a blade, to which, by means of a screw, is fixed a needle, the end of
which is sharp like that of the ordinary needles. The two needles and
their supports are actuated forward in the direction of the batten by
a driver impelled by a treadle and backward by a counterweight. At
the stroke of the batten one of the two needles being in the tissue
is drawn out and cuts, actuated by its sliding rod which the treadle sets
in motion; the driver then acts and the needle is withdrawn from the
tissuc, whilst the other needle actuated by its sliding rod re-enters the
passage reserved for the shuttle and comes back to the weaving point
forced back by the batten. The fourfold movement executed on the
low heald loom for a single piece is thus obtained by a single mechanism
on the bar loom whatever may be the number of pieces woven at the
same time. The batten of the loom is ascensional in its movement.
so that the shuttle may redescend so as not to hinder the working of
the needles, but this ascensional movement is suspended at the fifth
stroke for the passage of the needle to take place by means of a rod
in connection with the batten, and which on receding with the said
batten uncogs a picker by an oscillating treadle working every fifth
stroke. Each piece of velvet is sustained at the weaving point on
the instant the needles operate by a metal plate fixed to the foremost
cross piece.

WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent, bearing date the Eighteenth day of January, in the
year of our Lord One thousand eight hundred and sixty-eight, 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 license, that I, the said Henri Adrien Bonneville, my executors,
administrators, and assigns, or such others as I, the said Henri Adrien
Bonneville, my exccutors, 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 In
vention for "IMPROVEMENTS IN RIBBON LOOMS," a communication from
Christophe Balay, a person resident at St. Etienne, in the Empire of
France, aforesaid, Manufacturer, 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 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 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 :-
These improvements, represented in the annexed Drawings, relate
to the manufacture and the cutting out, mechanically and simul-
taneously on bar looms, of several pieces of terry ribbon velvet in as
perfect a manner as on the low heald loom with which a single piece
can alone be manufactured. Three essential conditions are necessary
to obtain this result-the passage of the cutting needles to the same
side, the prop of the piece at the weaving point, and a cording allowing
the nap to be tied by four bottom strokes with. only two needles.
To this effect on the foremost cross piece A of the loom, a sliding rod

page_text: for each needle B, B', is set, actuated with a to-and-fro movement
according to the axis of the foremost cross piece obtained by a treadle C,
Fig. 1, and a counterweight D. On each sliding rod and for each piece of
ribbon is fixed a support E on which slides a guide F supporting a blade
F to which by means of a screw a is fixed the needle G, the end of
which is sharp like that of the ordinary needles. The two needles
and their support as particularly shown in Fig. 1bts are actuated forward
in the direction of the batten by a driver H impelled by a treadle 6,
Fig. 4, and backward by a counterweight c, Fig. 4, at the stroke of
the batten as shown at No. 1, Fig. 1. One of the two needles being
in the tissue is drawn out and cuts, actuated by its sliding rod which
the treadle sets in motion as shown at No. 2; the driver then acts and
the needle is withdrawn from the tissue as shown at No. 3, whilst the
other needle which has remained in the tissue then actuated by its
sliding rod, the first needle re-enters the passage reserved for the
shuttle, as shown at No. 4, and comes back to the weaving point, as
shown at No. 5, and No. 1 forced back by the batten. The fourfold
movement executed on the low heald loom for a single piece is thus
obtained by a single mechanism on the bar loom whatever may be
the number of pieces woven at the same time. The forcing back of
the needle to the weaving point, as shown at No. 5, is seconded by a
metal plate at d, Fig. 2, which presses on the front part of the blade F
to which is fixed the needle. The batten a of the loom is ascensional in
its movement, as shown in Fig. 2, so that the shuttle may redescend so
as not to hinder the working of the needles, but this ascensional move-
ment is suspended at the fifth stroke for the passage of the needle to take
place by means of a connecting rod b, Fig. 5, in connection with the
batten a, and which on receding with the said batten uncogs a picker c
by an oscillating treadle e working every fifth stroke. Each piece of
velvet is sustained at the weaving point on the instant the needles operate
by a metal plate fixed to the foremost cross piece. As the needle
only enters the passage reserved for the shuttle at every fifth stroke
of the batten, the driver H is so disposed as to operate only at every
fifth stroke instead of operating fruitlessly at each stroke. With this
view I have disposed (Fig. 4) a treadle which by means of a wire e is
only actuated at every fifth revolution of the main driving shaft f of the
loom revolving once at every stroke by means of a wheel /, which
revolves once to every fourth revolution of the pinion of the main
shaft, the wire e not acting upon the treadle but every fifth stroke.

page_text: Fig. 3 represents isolated the guide, the elbowed blade armed with its
needles, and the support of the tissue M., which greatly ensures a good
manufacture by sustaining the weaving point, as also the needles forced
back to that point by the batten.
Having thus fully described the nature of the said Invention, and
the manner of carrying the same into effect, what I claim is, the
improvements in bar looms 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 Third day of July, in the
year of our Lord One thousand eight hundred and sixty-eight.
H. BONNEVILLE. (L.S.)
