IMPROVEMENTS IN LOOMS FOR WEAVING RIBBONS AND OTHER FABRICS
Year: 1860

page_text: LETTERS PATENT to Thomas Cole, of the City of Coventry, Ribbon
Weaver, and David Gardner, of the same City, Ribbon Loom Maker,
for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING RIBBONS AND
OTHER FABRICS"
PROVISIONAL SPECIFICATION left by the said Thomas Cole and David
Gardner at the Office of the Commissioners of Patents, with their
Petition, on the 29th November 1860.
We, THOMAS COLE, of the City of Coventry, Ribbon Weaver, and DAVID
GARDNER, of the same City, Ribbon Loom Maker, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING
RIBBONS AND OTHER FABRICS," to be as follows:―
The usual method in weaving ribbons is to form one shed or opening in the
warp for the ground, and afterwards to form another for the figure or facing
upon the ground. Now, our Invention consists in applying levers and slats
under the ordinary jacquard machines, so as to form two sheds or openings in
the warp at the same time by means of extra length of tugs or double-knotted
leash or strapping thread lifted by the aforesaid levers and slats, so that a
figured ribbon, the figure on which is produced by the shute or the weft, can be
made at a single motion or shute. Also two separate ribbons can be made in
each space of the batten at the same time, or two ribbons can be woven

page_text: together as one fabric. The Invention may also be applied to looms where
there is no jacquard machine, and to looms for weaving textile fabrics other
than ribbons.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Cole and David Gardner in the Great Seal Patent
Office on the 29th May 1861.
TO ALL WHOM THESE PRESENTS SHALL COME, we, THOMAS
COLE, of the City of Coventry, Ribbon Weaver, and DAVID GARDNER, of the
same City, Ribbon Loom Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of November, in the year of our
Lord, One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Cole and David Gardner, Her special licence that we, the
said Thomas Cole and David Gardner, our executors, administrators, and
assigns, or such others as we, the said Thomas Cole and David Gardner,
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 LOOMS FOR
WEAVING RIBBONS AND OTHER FABRICS," upon the condition (amongst others)
that we, the said Thomas Cole and David Gardner, or one of us, our exccutors
or administrators, by an instrument in writing under our or their, or one of
our or their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 we, the said Thomas Cole and David Gardner, do
hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, (reference being had to the Drawings here-
unto annexed, that is to say) :-
The usual method in weaving ribbons is to form one shed or opening in the
warp for the ground, and afterwards to form another for the figure or facing

page_text: upon the ground. Now, our Invention consists in applying levers and slats,
or shafts of wood, iron, or other suitable materials under the ordinary jacquard
machines, so as to form two or more sheds or openings in the warp at the
same time, by means of extra length of tugs or double-knotted leash or
strapping thread lifted by the aforesaid levers and slats, so that a figured
ribbon, the figure. on which is produced by the shute or the weft, can be made
at a single motion or shute. Also two separate ribbons can be made in each
space of the batten at the same time, or two ribbons can be woven together as
one fabric. The Invention may also be applied to looms where there is no
jacquard machine, and to looms for weaving textile fabrics other than ribbons.
Figure 1 of the accompanying Drawings represents a front view of the
lashing.and harness, and an end view of the shafts, levers, and tugs, together
with the method whereby the jacquard machine lifts the harness or leashes, all
in accordance with our Invention.
a, a, are the tugs; b, b, the ends of the levers; c, c, are tugs connecting the
levers with the slats or shafts; D, D, are the slats or shafts; E, E, are tlie
loops working on the slats or shafts; F, F, are the lashing connecting the
loops with the leashes; G is the compass board; H, H, are the leashes at
different heights, as elevated by the lever.
Figure 2 is a side elevation showing how the hook rods i, i, of the jacquard
machine lift the end of the levers b, b, which run the same height as the
griff K; C, C, are tugs, which can be placed on any part of the levers b, b, so
as to raise the shafts D, D, and elevate the leashes H, H, to any intermediate
height of shed; E, E, are loops connecting the tugs a, a, showing the shafts
D, D, passing through the loops E, E, and forming the middle line of the
ground shed; F, F, are the lashing connecting the loops with the leashes;
J, J, show the hooked rods of the jacquard machine forming the brocade
or figure shed.
Figure 3 shows a side elevation of the jacquard machine with the bottom
part of hooked rods Number 1 and 2 so arranged as to avoid the use of the
tugs a, a, as well as the loops E, E, in Figure 2. The hooked rod No. 3
shows the lower part retaining the loop E. Each of the three hooks is so
arranged as to enable the lash to be attached or removed without the necessity
of tying or noosing. The slats or shafts D, D, pass through No. 1 and 2
hooked rods, and gain the same advantage of elevation as is obtained in
Figure 2 by the slats or shafts D, D, passing through the loop E, E. By
adding two loops to each hooked rod, a 400 machine raises as many threads
as a 750 machine constructed in the ordinary manner, and in a similar pro-
portion for machines of higher or lower number.

page_text: -And having now described the nature of our said Invention, and in what
manner the same is to be performed; we-declare that we do not limit our-
selves to the precise details herein-before described, for the same may be varied
without departing from our Invention, by, for example, the employment of
rollers, levers, slats, and shafts, or by means of pulleys, levers, and slats, or the
levers may be dispensed with, by using tugs or cords which remain slack
during part of the action; but what we claim as our improvements in looms
for weaving ribbons and other fabrics is, forming two or more sheds or
openings in the warp at the same time, by the methods and in manner herein-
before described and illustrated in the accompanying Drawings.
In witness whereof, wc, the said Thomas Cole and David Gardner, have
hereunto set our hands and seals, the Twenty-fifth day of May,
One thousand eight hundred and sixty-one.
Signed, sealed, and delivered by the
said Thomas Cole and David
Gardner, in the presence of,
THO. BROWETT, Solicitor,
-Coventry.
