IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1853

page_text: LETTERS PATENT to James Stocks, Junior, of Ovenden, in the
Parish of Halifax, in the County of York, Manufacturer, for the
Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 9th August 1853, and dated the 1st June 1853.
PROVISIONAL SPECIFICATION left by the said James Stocks at
the Office of the Commissioners of Patents, with his Petition, on
the 1st June 1853.
I, JAMES STOCKS, Jun', do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING" to be as
follows:-
The improvements apply particularly to the mode of working that part
of a loom known as the "riser." I purpose to place or fix a pinion a,
(seen in the Drawings) on to the low shaft b, which will drive a
wheel c, on the counter shaft, on which I place a tappet working a
lever d, the other or upper end of which lever by means of the rod e,
communicating with the riser, such riser is operated upon, and by these
means I can arrange the wheels and tappits so as to work the "riser,"
and to vary the number of "picks," up and down, of the "box" at
pleasure.

filed by the said James Stocks in the Great Seal Patent Office,
on the 26th November 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES STOCKS, Junior, of Ovenden, the Parish of Halifax, in the
County of York, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, bearing date the First day of June, in the
year of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did.for Herself, Her heirs and successors,
give and grant unto me, the said James Stocks, Junior, Her especial
license that I, the said James Stocks, Junior, my executors, administra-
tors, and assigns, or such others as I, the said James Stocks, Junior, 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 James Stocks, Junior, by an instrument in writing under my hand
and scal, 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
Royal Letters Patent.
NOW KNOW YE, that I, the said James Stocks, Junior, do hereby
declare the nature of my 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):
My Invention relates to the mode or method of working that part
of a loom, generally known as the " riser," which is used to raise and
fall the shuttle box at stated periods or intervals, for the purpose of
varying the number of picks, so as to form different patterns on the
surface of the fabric, which improvements I accomplish by fixing a

page_text: pinion on the low shaft, with intermediate change wheels to drive a
wheel on the counter shaft, on which I fix a plate; to this plate I fix
or attach different sized segments according to the number of picks or
pattern required; I also fix a lever on the frame of the loom, one
end of which has a cone pulley, so placed that the said segments during
the revolution of the plate come in contact with and depress it, the other
end of the said lever being connected to a vertical rod, which extends to
the shuttle box and raises it every time; one of the segments depresses
the said lever, and by altering the size and form of the said segments I
can vary the number of picks and pattern at pleasure. These my said
improvements will be easily understood by reference to the accompany-
ing sheet of Drawings, which represents an end elevation of an
ordinary loom with my said improvements attached. a, is the frame
of the loom; b, the driving pulleys; c, the driving shaft; d, the
connecting rod; e, the sword arm; f, the tappet shaft, upon which is
fixed the toothed wheel g, driving the larger toothed wheel h, and
pinion i, which turns the toothed wheel and plate k, upon the side of
which are bolted the cams or segments 1, acting as they revolve upon
the roller or pulley m, and remove it from the periphery of the plate k;
the roller or pulley m, is attached to one end of the lever n, turning
on its fulcrum o, to the other end is jointed the connecting rod p, to
which the shuttle box q, is attached. Thus it will be clearly perceived
that when the roller or pulley m, presses against the periphery of the
plate k, the connecting rod and shuttle box are in their lowest position.
but when the cams or segments press against the said pulley the con-
necting rod and shuttle box are in their highest position, which varying
position of the shuttle box allows for the variation of the picks and
pattern, as is easily understood by any person conversant with the art of
weaving.
Having thus fully explained the nature and particulars of my said
Invention, I desire it to be distinctly understood that I do not confine
myself to the exact details herein described, as such may be varied or
modified without departing from the principle thereof, namely, by
employing two, three, or four shuttle boxes by the use of various sized
cams; and I claim as of my Invention, and which to the best of my

page_text: knowledge and belief has not been hitherto used within this realm, the
mode or method of working the riser of the shuttle box by means of
portable cams or segments, varying in form and size to the pattern
required, acting on the lever and vertical rod as herein described and
illustrated.
In witness whereof, I, the said James Stocks, Junior, have here-
unto set my hand and seal, this Thirteenth day of October, One
thousand eight hundred and fifty-three.
JAMES STOCKS, JUN".
(L.S.)

James Stocks, Junior,
