AN IMPROVED METHOD OF THROWING THE SHUTTLES OF LOOMS
Year: 1862

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County
of Middlesex, Engineer and Patent Agent, for the Invention of "AN
IMPROVED METHOD OF THROWING THE SHUTTLES OF LOOMS."-A communi-
cation from abroad by Jean Henry Cazal, of 29, Boulevart St. Martin,
Paris, Civil Engineer.
Sealed the 21st November 1862, and dated the 29th May 1862.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the
29th May 1862.
I, WILLIAM CLARK, of 53, Chancery Lane, Engineer and Patent Agent,
do hereby declare the nature of the said Invention for "AN IMPROVED METHOD
OF THROWING THE SHUTTLES OF LOOMS," to be as follows:-
The various improvements in weaving have hitherto failed to remedy the
defective modes of throwing the shuttle, which throwing of the shuttle forms
an important function of the loom.
This Invention relates to an improved method of throwing the shuttle: a
given distance at a uniform and regular speed by the application of the
attractive force of a magnet or electro-magnet as a motor; thus a shuttle is
furnished with an iron armature, acted on by a magnet or electro-magnet
placed in proximity to it, and having a suitable motion imparted to it at a.
given speed, which will be thence transmitted to the shuttle.

page_text: The results of employing this improved method of driving the shuttle are,―
First, prevention of all jerking and consequent rupture of the threads.
Secondly, counteraction of the dead weight of the shuttle, which admits of
ts carrying an additional amount of thread.
Thirdly, the shuttle never stops at any point of its traverse.
Fourthly, great saving of time by reason of its uniform motion, uninterrupted
by any rupture of the thread or stoppage of the shuttle.
Fifthly, the weaving may be effected with more uniformity than formerly.
Sixthly, the capability of weaving all kinds of fabrics, the widths of which
will be limited only by the size of the other parts of the loom, independently
of the throw of the shuttle.
Seventhly, in this manner fabrics may be woven of great width, thereby
obviating the necessity of having joins or seams.
This Invention may be applied for imparting motion to the shuttles of all
kinds of looms, whatever may be their nature or the form of shuttle employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the
28th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Clark, Her special licence that I, the said William
Clark, my executors, administrators; and assigns, or such others as I, the
said William Clark, my 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 "AN
IMPROVED METHOD OF THROWING THE SHUTTLES OF LOOMS," a communication.to
me from abroad by Jean Henry Cazal, of 29, Boulevart St. Martin, Paris,
Civil Engineer, upon the condition (amongst others) that I, the said William
Clark, my executors or administrators, by an instrument in writing under my,

page_text: or their, or one of their hands and seal, 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 William Clark, 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 (that is to say):-
The various improvements in weaving have hitherto failed to remedy the
defects in the different modes of throwing the shuttle, which throwing of the
shuttle forms an important function of the loom.
This Invention relates to an improved method of throwing the shuttle a
given distance at a uniform and regular speed by the application of the attractive
force of the magnet or electro-magnet as a motor; thus a shuttle is furnished
with an iron armature, acted on by a magnet or electro-magnet placed in
proximity to it, and having a suitable motion imparted to it at a given speed,
which will be thence transmitted to the shuttle.
The advantages of employing this improved method of driving the shuttle
are,-
1st, prevention of all jerking and consequent rupture of the threads.
2ndly, counteraction of the dead weight of the shuttle, which permits of its
carrying an additional amount of thread.
3rdly, the shuttle never stops at any point of its traverse.
4thly, great saving of time by reason of its uniform motion, uninterrupted
by any rupture of the thread or stoppage of the shuttle.
5thly, the weaving may be effected with much more uniformity than formerly.
6thly, the capability of weaving all kinds of fabrics, the widths of which
will be limited only by the size of the other parts of the loom, independently
of the throw of the shuttle.
7thly, in this manner fabrics of great width may be woven, thereby obviating
the necessity of having joins or seams.
The motion of the shuttle may be produced by the influence of the electro-
magnetism alone constituting the motive power, or it may be obtained by the
aid of a self-acting apparatus, and thus form a self-acting shuttle.
Having described the nature of this Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be protectedl
by the herein-before in part recited Letters Patent, is, the means herein-before
described of imparting motion to the shuttles of all kinds of looms, whatever

page_text: may be their nature or the form of shuttle, or the nature of the magnetic or
electro-magnetic power employed.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Twenty-sixth day of November, in the year of our
Lord One thousand eight hundred and sixty-two.
Witness,
JAMES DAISH,
53, Chancery Lane,
London.
