IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1863

page_text: LETTERS PATENT to Arthur Bastow, of Bradford, in the County of
York, Manufacturer, for the Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING."
Sealed the 18th November 1863, and dated the 27th May 1863.
PROVISIONAL SPECIFICATION left by the said Arthur Bastow at the
Office of the Commissioners of Patents, with his Petition, on the 27th
May 1863.
I, ARTHUR BASTOW, of Bradford, in the County of York, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING," to be as follows:-
My Invention has particular reference to that kind of loom known as the
circular box loom," and consists in a combination of parts herein-after
described, by means of which fabrics known by the name of "checks" and
"transverse stripes" may be woven. For this purpose I place levers fixed on
an independent shaft or spindle in such a position relatively to the parts of the
loom by which the "circular box" is usually actuated; that motion is given
to them at such times as may be required for weaving the various classes of
fabrics enumerated above. The motion thus given to the shaft or spindle
above named is communicated by means of another lever on the same shaft.
or spindle to an independent lever, which, having a projection on its end,
retains the pins or catches affixed for the purpose to the double cam which
actuates the healds of the loom (and which in this instance is worked by a

page_text: clutch fixed on its axis) for such period as may be requisite, thus keeping what
is technically termed the "shed" open. The "bar" in the fabric having been
woven during this interval the independent lever above named is allowed to
drop by means of a reverse motion releasing the double cam above named
from the clutch also above named. The said double cam is restored to its
usual position by the pressure of a spring placed on that side of it furthest
from the pins or catches above named, and the weaving is continued as
ordinarily, until it is necessary for such operation to be repeated.
This arrangement may be adapted to the crank or driving shaft of the loom
as well as to the lower or cam shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Arthur Bastow in the Great Seal Patent Office on the
27th November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARTHUR
BASTOW, of Bradford, in the County of York, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Arthur Bastow, Her special licence that I, the said Arthur Bastow, my
executors, administrators, and assigns, or such others as I, the said Arthur
Bastow, 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 "IMPROVEMENTS IN LOOMS FOR
WEAVING," upon the condition (amongst others) that I, the said Arthur
Bastow, 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.
NOW KNOW YE, that I, the said Arthur Bastow, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had to the Sheet of Drawings' hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
My Invention has particular reference to that kind of loom known as the
"circular box" loom, and consists in a combination of parts herein-after
described, by means of which fabrics known by the names of "checks" and
transverse "stripes" may be woven. For this purpose
For this purpose I place levers fixed
on an independent shaft or spindle in such a position relatively to the parts of
the loom by which the "circular loom" is usually actuated, that motion is
given to them at such times as may be required for weaving the various
classes of fabrics enumerated above. The motion thus given to the shaft or
spindle above named is communicated by means of another lever on the
same shaft or spindle to an independent lever, which, having a projection on
its end, retains the pins or catches affixed for the purpose to the double cam
which actuates the healds of the loom (and which in this instance is worked
by a clutch fixed on its axis) for such period as may be requisite, thus keeping
what is technically termed the "shed" open. The "bar" in the fabric
having been woven during this interval, the independent lever above named
is allowed to drop by means of a reverse motion releasing the double cam
above named from the clutch also above named. The said double cam is
restored to its usual position by the pressure of a spring placed on that side
of it furthest from the pins or catches above named, and the weaving is
continued as ordinarily until it is necessary for such operation to be repeated.
This arrangement may be adapted to the crank or driving shaft of the loom
as well as to the lower or cam shaft

page_text: contact with the catch f³, prevents the revolution of the same, and the double
cam connected with or a pair of it. The spring m becomes compressed from
pressure against the female clutch i of the male clutch g, which now revolves
by itself. The double cam being held stationary, the healds of the loom
(not shown but worked by the cams in the ordinary manner) are neces-
sarily stationary too, and thus the "shed" is kept open and the "bar" or
stripe is woven. This accomplished, the ordinary mechanism reverses the
rods c and c¹, lifting up the crank a, and thus allowing the lever f to drop,
freeing the catch f', whilst the spring m thrusts the cam and clutch in contact
with the fast clutch g, and the healds are again in motion.
Having now described the nature of my Invention, and in what manner
the same is performed, I wish it to be understood that I do not confine myself
to the precise details shewn; but what I claim as and of my Invention is,
the method of weaving bars or stripes by means or apparatus substantially
as described.
In witness whereof, I, the said Arthur Bastow, have hereunto set my
hand and seal, this Twenty-fifth day of November, in the year of our
Lord One thousand eight hundred and sixty-three.
Witness,
JOHN CODD,
Clerk to J. Buckley Sharp,
Auctioneer, &c., Bradford.
