Year: 1861

page_text: LETTERS PATENT to Marc Antoine François Mennons, of the British
and Foreign Patent Offices, 39, Rue de l'Echiquier, Paris, in the Empire
of France, for the Invention of "IMPROVEMENTS IN RIBBON LOOMS."-A
communication from abroad by Messrs. Benoit Durand and Claude Crozet,
persons resident at No. 11, Rue de la Bourse, St. Etienne (Loire).
PROVISIONAL SPECIFICATION left by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his Petition,
on the 6th September 1861.
I, MARC ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent
Offices, 39, Rue de l'Echiquier, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN RIBBON LOOMS,"
to be as follows:-
These improvements consist in the modification, as below described, of
jacquard bar and other ribbon looms, with a view to permit of double pieces
being simultaneously manufactured under the eye of the weaver, who is thus
enabled to detect and repair at once the faults which may occur in the course
of the work with as much facility as in the single piece looms at present
employed.
Figure 1 of the accompanying Drawing represents a reed divided into two
parts for the production of the two superposed pieces. Figure 2 represents
the cramp ("crampon"); A is a portion of the top of the batten; B is the

page_text: support of the same. Figure 3 represents the front of the weaver's bench;
C, D, are the superposed pieces of ribbon; E, E, are the glass rods over which
the ribbons pass on their way to the rollers. Figure 4 represents the left-hand
side of the loom; F is the regulating mechanism of the bar of the under
rollers which receive the upper ribbon (C, Fig. 3); G is the bar; and H, the
upper rollers receiving the lower ribbon (D, Fig. 3). Figure 5 represents
the right-hand.side of the loom; I is the regulating mechanism of the bar of
the upper rollers receiving the lower ribbons; J are the under rollers receiv-
ing the upper ribbons. Figure 6 represents the complete series of rollers;
Kis the front of the weaver's bench; L is the left-hand side of the loom.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by tho said Mare Antoine François Mennons in the Great Seal Patent
Office on the 3rd March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent Offices, 39,
Rue de l'Echiquier, Paris, in the Empire of France, send greeting.
WHEREAS 1er most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of September, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fifth year of IIer reign,
did, for Herself, Iler heirs and successors, give and grant unto me, the said
Mare Antoine François Mennons, Her special licence that I, the said Marc
Antoine François Mennons, my executors, administrators, and assigns, or such
others as I, the said Marc Antoine François Mennons, my executors, adminis-
trators, 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 RIBBON LOOMS," (a communication from
Messrs. Benoit Durand and Claude Crozet, persons resident at No. 11, Rue de
la Bourse, St. Etienne (Loire), upon the condition (amongst others) that I,
the said Marc Antoine François Meunons, 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.

page_text: NOW KNOW YE, that I, the said Marc Antoine François Mennons, 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, reference being had to the figures of the accompanying
Drawing and to the letters marked thereon, that is to say:-
These improvements consist in the modification, as below described, of
jacquard, bar, and other ribbon looms, with a view to permit of double super-
posed pieces being simultaneously manufactured under the eye of the weaver,
who is thus enabled to detect and repair at once the faults which may occur
in the course of the work with as much facility as in the single-piece looms at
present employed.
Figure 1 of the accompanying Drawing represents a reed divided into two
parts for the production of the two superposed pieces. Figure 2 represents
the cramp ("crampon"); A is a portion of the top of the batten; B is the
support of the same. Figure 3 represents the front of the weaver's bench;
C, D, are the superposed pieces of ribbon; E, E, are the glass rods over which
the ribbons pass on their way to the rollers. Figure 4 represents the left-hand
side of the loom; F is the regulating mechanism of the bar of the under
rollers which receive the upper ribbons (C, Fig. 3). Figure 5 represents the
right-hand side of the loom; I is the regulating mechanism of the bar of the
upper rollers receiving the lower ribbons; J, J, are the under rollers receiving
the upper ribbons. Figure 6 represents the complete series of rollers; K is
the front of the weaver's bench; L is the left-hand side of the loom. Figure 7
represents the distribution of the improved mechanism in the complete loom ;
A is the upper part of the batten, which is weighted and strengthened by the
insertion of an iron plate or band covered over with a wooden ledge; B is the
under portion of the batten; C, cramps; D, double reeds, backed up by an
iron framework, by which they are prevented from deviating in the working
of the loom; E, upper, and F, lower pieces of the superposed ribbons, sepa-
rated from each other by a distance of about four inches; G, bench; H, iron
supports for the small tension rods I, on which pass the upper pieces of ribbon
on their way to the winding rollers K. The object of this arrangement is to
correct the slackness and consequent liability to irregular weaving of these
upper pieces (E), the rollers (K) of which are set at a greater distance from
the reeds than those (J) of the lower pieces F; L, L, arms of the hand bar;
M, driving wheel. The secondary mechanical details of the loom are for
the most part omitted from the Drawing, being too well known to require
description.
Having now described the nature of the said improvements and the manner

page_text: of carrying them into effect, I declare that what I claim is, the application
to jacquard, bar, and other ribbon looms, of double sets of reeds, healds, and
rollers, so constructed and arranged as to permit tho simultaneous manu-
facture, under the eye of the weaver, of double superposed pieces of the tissue,
substantially as herein set forth and represented in the Figures of the accom-
panying Drawing.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and seal, this Twenty-fifth day of February, in
the year of our Lord One thousand oight hundred and sixty-two.
