IMPROVEMENTS IN LOOMS FOR WEAVING RIBBONS AND OTHER LIKE GOODS
Year: 1859

page_text: LETTERS PATENT to Frederick Edwards and William Edwards, of the City
of Coventry, Machinists, for the Invention of "IMPROVEMENTS IN LOOMS
FOR WEAVING RIBBONS AND OTHER LIKE GOODS."
Sealed the 13th October 1859, and dated the 18th April 1859.
PROVISIONAL SPECIFICATION left by the said Frederick Edwards and
William Edwards at the Office of the Commissioners of Patents, with
their Petition, on the 18th April 1859.
We, FREDERICK EDWARDS and WILLIAM EDWARDS, of the City of Coventry,
Machinists, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LOOMS FOR WEAVING RIBBONS AND OTHER LIKE GOODS," to be as
follows:-
This Invention relates to the working of shuttles in ordinary narrow-fabric
looms, where two or more sets of shuttles are used, and consists in the employ
ment of treddles so constructed that they can be brought in contact with levers
communicating motion to the shuttles, the treddles being worked by two tapets
on the tapet shaft; these treddles are connected with a lever that is worked
by a cam on the tapet shaft which gives an oscillating motion to the treddles,
which motion connects and disconnects them with the levers connected with
the shuttles. The shuttle levers are worked in joints and are brought in

page_text: contact with the treddles by taper slide propellers, which are connected with
the jacquard machine. As the machine rises, so the action is communicated
to the propellers; the cards of the machine cause the propellers to rise, and
by so doing bring the shuttle lever in contact with the treddles, and the lever
is borne down by the treddle, thus taking the shuttles connected with that
lever through the warp. By the sliding of the propellers motion is given to
any set of shuttles, as the figure of the work requires.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Edwards and William Edwards in the Great Seal
Patent Office on the 18th October 1859.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
EDWARDS and WILLIAM EDWARDS, of the City of Coventry, Machinists, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of April, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Frederick Edwards & William Edwards, Her special licence that
we, the said Frederick Edwards & William Edwards, our executors, admi-
nistrators, and assigns, or such others as we, the said Frederick Edwards and
William Edwards, our 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 LIKE GOODS," upon the condition
(amongst others) that we, the said Frederick Edwards and William Edwards,
or one of us, our executors or administrators, by an instrument in writing
under our, or one of our, 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 we, the said Frederick Edwards and William
Edwards, do hereby declare the nature of our said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say:-
This Invention relates to the working of shuttles in ordinary narrow-fabric
looms, where two or more sets of shuttles are used, and consists in the employ-
ment of treddles so constructed that they can be brought in contact with levers
communicating motion to the shuttles, the treddles being worked by two
tappets on the tappet shaft; these treddles are connected with a lever that is
worked by a cam on the tappet shaft, which gives an oscillating motion to the
treddles, which motion connects and disconnects them with the levers con-
nected with the shuttles. The shuttle levers are worked in joints, and are
brought in contact with the treddles by taper slide propellers which are
connected with the jacquard machine. As the machine rises, so the action
is communicated to the propellers; the cards of the machine cause the
propellers to rise, and by doing so bring the shuttle lever in contact with the
treddles, and the lever is borne down by the treddle, thus taking the shuttles
connected with that lever through the warp. By the sliding of the propellers
motion is given to any set of shuttles as the figure of the work requires.
In Figure 1 of the accompanying Drawings we have shewn a side view of
our apparatus, as fixed under a ribbon "loom" of the ordinary construction;
Figure 2 is a plan of the same.
b
A, A, are two treddles, working loosely on either end of a rocking lever B,
which rocking lever is actuated by a connecting rod C, C, which receives a
to-and-fro motion by means of an eccentric cam D on a cross shaft E working
between two rollers a, a, fixed on the rod C, C; the rocking lever B is
supported by a vertical pin on the frame of the apparatus. At the back of
the apparatus and near the bottom thereof a pin 6 passes across, supporting one
end of a series of short vertical levers F; the upper parts of these levers are
enlarged and forked, and between the forks small rollers c, c, are fitted; these
rollers, with the vertical levers F, are kept pressed against a series of taper
slide propellers G springs, as shewn in Figure 1; these propellers are
suspended by cords connected to the jacquard, and in their upward movement
act against the rollers c, c, and push forward one of the series of levers H, H,
there being one lever to each propeller. These levers are connected to the
forked ends of the short vertical levers F, as shewn; the other ends of the
levers H are furnished with straps or bands, which pass over small pulleys d,
and take a three-quarter turn over or under a larger pulley J; this last-.
named pulley has two grooves formed round it, into one only of which grooves.

two of the straps before mentioned are secured. The other
is furnished
with straps from the shuttle guidé frame. The levers H, H, are kept parallel
by working between guides e, e, fixed to an additional frame K, placed near
the front ends of the treddles A. At each side of the back end of the set of
levers H there is placed a forked end of the treddle A, and from the upper
part of the forks a vertical pin frises, which pin takes into a hole formed for
it at the end of the rocking lever B. The treddles A are carried along and
extend a little in front of the levers, and have each a cranked plate 9 pro-
jecting inward; these treddles A are carried downward by two tappets M, M,
(so placed on the cross shaft E, that one only is at work at a time) pressing
against an incline fixed thereon, but removable, in order to admit of the
regulation of the throw of the shuttle, or the tappet rollers may work in slots
for that purpose, as shown in Figure 3. Near the ends of the treddles another
strap or band (one end to each treddle) is fixed, which strap passes over
another pulley N. The tappets are furnished with small rollers to work
against the incline to reduce friction.
A front view of the straps or bands
and pulleys is shewn at Figure 4. The propellers G have tail pieces h fixed
to them, on which a lever or plate presses to press them down into proper
position. The lever is centred to the frame K, and is carried down by a cam
on the tappet shaft, and kept working against the cam by a spring.
The operation of the apparatus is as follows:-When the cross shaft is set
in motion one of the tappets will carry down one of the treddles by pressing
on the incline; and the eccentric cam having pushed the rocking lever with
the treddles into proper position, will, by means of the cranked plate on the
treddle push down all the levers that have been pushed out by the slide
propellers acted upon by the jacquard. It follows that the pushing down of
the levers will, by means of their straps, cause the pulley J to partially rotate,
and thus work the colored thread shuttle required for the desired pattern.
We do not at all times place our apparatus under the loom, but give it any
convenient position.
Having now described the nature of our said Invention, and in what manner
the same is to be performed, we declare that we claim,-
First, the construction, arrangement, and combination of all the parts of
the apparatus herein-before described and illustrated in the accompanying
Drawings.
Secondly, the method of imparting to-and-fro movements to the levers
by means of taper slide propellers acted upon by the jacquard, as herein-before
described.

page_text: Thirdly, the method of putting in action the treddles, straps, and pulleys,
for the purpose of working various colored thread shuttles for weaving ribbons
and other like goods, as herein-before described and represented in the
Drawings hereunto annexed.
In witness whereof, we, the said Frederick Edwards and William Edwards,
have hereunto set our hands and seals, this Seventeenth day of October,
One thousand eight hundred and fifty-nine.
