IMPROVEMENTS IN MACHINERY FOR WEAVING FIGURED FARRICS
Year: 1855

page_text: LETTERS PATENT to Samson Woller, of Bradford, in the County of York,
Manufacturer, and Illingworth Butterfield, of the same Place, Manager,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR WEAVING FIGURED
FARRICS."
Sealed the 1st February 1856, and dated the 2nd August 1855.
PROVISIONAL SPECIFICATION left by the said Samson Woller and Illing-
worth Butterfield at the Office of the Commissioners of Patents, with
their Petition, on the 2nd August 1855.
We, SAMSON WOLLER, of Bradford, in the County of York, Manufacturer,
and ILLINGWORTH BUTTERFIELD, of the same Place, Manager, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR WEAVING
FIGURED FABRICS" to be as follows:-
Our improvements consist in allowing the hooks of the jacquard machine
to be entirely at rest in their seats and completely free from the knives of the
grife at the time that they are pressed back by the needles acted upon by
the cards and cylinder, whereby greater ease and freedom is imparted to the
working of the machine, and which in consequence can be worked at a greater
speed than by the modes hitherto generally adopted; the cards may also be
made of lighter card paper than required in the ordinary mode of working.

page_text: In order to effect this, the jacquard cylinder is worked independently of the
other parts of the jacquard machine, and for this purpose we have two cranks
on the crank shaft of the loom; but we do not limit ourselves to this
arrangement, as the jacquard cylinder may be worked in other ways. Our
improvements also consist in being able to disengage the cylinder frame, so
that the jacquard cylinder and the cards may be turned backwards or forwards
by hand, independently of the loom and of the other parts of the jacquard
machine.
Another of our improvements consists in keeping the harness steady and
free from vibration, by attaching each harness thread to a wire passing through
a spring box. When a harness thread has been raised by the jacquard, it is
brought down partly by the weight of the wire and partly by the spring.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samson Woller and Illingworth Butterfield in the Great
Seal Patent Office on the 1st February 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMSON
WOLLER, of Bradford, in the County of York, Manufacturer, and ILLINGWORTH
BUTTERFIELD, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of August, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Samson Woller and Illingworth Butterfield, Her special license that we, the
said Samson Woller and Illingworth Butterfield, our executors, administrators,
and assigns, or such others as we, the said Samson Woller and Illingworth
Butterfield, 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 MACHINERY FOR
WEAVING FIGURED FABRICS," upon the condition (amongst others) that we, the
said Samson Woller and Illingworth Butterfield, our executors or adminis-
trators, 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

page_text: 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 Samson Woller and Illingworth
Butterfield, 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 Specification thereof, reference being had
to the accompanying Sheet of Drawings (that is to say) :-
:-
The nature of our said Invention consists, first, in allowing the hooks of a
jacquard machine to be entirely at rest and free from the knives of the grife
at the time they are pressed back by the cards and cylinder, whereby great
ease and freedom is obtained in working the machine, consequently the cards
may be made of lighter card paper, and the machine may be worked at a
greater velocity than usual.
Secondly, in the means of disengaging the cylinder or swing frame, so that
the cylinder and the cards may be worked backwards or forwards inde-
pendently of the other parts of the machine.
And, lastly, in keeping the harness steady and free from vibration by means
of weight, wires, and springs.
And in order that our Invention may be fully understood and readily carried
into effect, we will proceed to describe the accompanying Sheet of Drawings.
Figure 1 is an end view, and Figure 2 a front view, of a loom with a
jacquard machine to which our improvements are applied. a is the crank
shaft of the loom; b, the jacquard machine; c, the swing frame of the jacquard
cylinder d; e is the grife, which is worked up and down by the lever f and
crank pin g, fixed to the fly wheel h, or to a crank on the shaft a, in the
usual manner.
At the other end of the crank shaft is a crank i, which gives motion to the
jacquard cylinder, in the following manner:-To the crank i is fixed the crank
pin j, to which is jointed the lower end of the rod k; the upper end of this rod
is jointed to the pin l, fixed in the lever m, which is keyed on the shaft n;
near the other end of this shaft is fixed the lever o, which is furnished with a
pin for giving motion to the link p, which is jointed to a prolongation of the
swing frame c. By this arrangement every revolution of the crank shaft
imparts the requisite to and fro motion to the swing frame c and jacquard
cylinder d. The amount of motion can be regulated by varying the distance of
the pins j and from the fulcrum of the crank i and lever m.
The relative position of the crank pin g which works the grife, and the

page_text: crank pin which moves the jacquard cylinder, is such, that the hooks of the
jacquard are entirely at rest and free from the knives of the grife when
the cylinder approaches to bring the jacquard card against the needles, by
which the hooks are selected and pressed back in the ordinary manner. By
this means great ease and freedom is imparted to the working of the machine,
consequently the cards may be made of lighter card paper, and the machine
worked at a greater speed than usual.
I wish to remark here, that although I have shewn the cranks at opposite
ends of the crank shaft for working the various parts of the jacquard machine,
I do not confine myself to this arrangement, as the cranks may be at the same
end of the crank shaft, or other combinations of machinery may be adopted
to effect the same object. The link p is made with an open slot fitting on the
pin of the lever o, and with a handle; consequently, by lifting the slot in the
link p off the pin in the lever o, the swing frame is disengaged from the loom,
and the cylinder is then at liberty to be worked by hand, for the purpose of
moving the cards backward or forward independently of the other parts of the
loom.
Our improvements in keeping the harness steady and free from vibration
are shewn in reference to Figure 3. In this view, r, are two of the threads
of the harness, and to each harness thread is attached a wire s, s. These wires
are guided by the boards t, t, forming part of a spring box; each wires has a
light spring coiled around it; the upper ends of these springs bear against
the upper board t, and the lower ends bear on a pin projecting from the wires.
By this arrangement, when a harness thread is raised it has to overcome
the weight of the wires and the resistance of the spring u, as shewn in the
right-hand wire; but when the grife descends, each harness thread is brought
down by the weight of the wires and the elastic force of the spring u, the
combined action of the weight and the spring effectually preventing the
vibration occasioned by weights without springs.
In order to prevent the springs from getting strained too much, it will be
advisable to cause the spring box to move slightly with every up and down
motion of the engine. Instead of the pin above referred to, the lower ends
of the springs may be supported by shoulders, made of india-rubber or gutta
percha or other suitable material secured to the wires.
Having thus described the nature of our Invention, and the manner of
perforining the same, we would have it understood that we do not limit our-
selves to the details herein set forth, as the same may be varied; but that what
we do claim is,-

page_text: First, allowing the hooks of a jacquard machine to be entirely at rest
and free from the knives of the grife at the time they are pressed back by
the cards.
Secondly, lisengaging the cylinder or swing frame to allow the cards to
be worked backwards or forwards independently of the other parts of the
machine.
And, lastly, the combination of parts shewn and described for preventing the
vibration of the harness.
In witness whereof, we, the said Samson Woller and Illingworth Butter-
field, have hereunto set our hands and seals, this Twenty-ninth day
of January, in the year of our Lord One thousand eight hundred and
fifty-six.
