missioners of Patents, with their Petition, on the 15th July 1874.
WC, JAMES SAMUEL COOKE, of the Firm of Messrs. Cooke, Sons, and
Law, of Liversedge, in the County of York, Carpet Manufacturers, and
WILLIAM IRVING, Loom Tuner, and FREDERICK HOWARTH, Mechanic,
of the same Place, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates,―

page_text: boxes in looms wherein change shuttles are required, and the object
of our improvements is to render. the mechanism simple and not liable
to breakage in case of disarrangement of the working parts.
The shuttle boxes are supported in their guides or framework by
means of pegs or pins and other projections on the back of the boxes,
which rest upon notches formed in two upright rods or levers, one of
which is hinged to the frame at cach side of the boxes. On the top
of one of these rods or levers, and projecting above the top of the hand
rail is a friction pulley or bowl, and to the end frame of the loom is
hinged, at a point intermediate of the ends thereof, a lever which
projects forward over the shuttle box. The projecting end of this
When in its normal
lever is broad and forms an incline or cam.
position it is kept clear of the friction pulley on the top of the lever
supporting the shuttle boxes before mentioned by means of a bell-
crank lever attached likewise to the end frame, one arm of which is
notched, and by acting on the back end of the projecting lever the cam
or incline end is elevated above the shuttle boxes.
When it is required to lower the boxes the bell-crank lever, by means
of a cord communicating with the jacquard, is raised and releases the
projecting lever, the end of which falls and comes in contact with
the friction pulley before mentioned, the cam or incline acting on or
pushing sideway the said friction pulley and supporting lever, which
by an arrangement of springs removes the lever at the other side of the
boxes and allows them to drop..
For raising the boxes we employ a lever hinged to the end frame,
which is acted upon at about the centre thereof by a cam mounted
upon à shaft extending underneath the loom from end to end. This
cam acts on the under side of the said lever, raising the same, and the
unattached end takes into one of a series of notches formed in a rigid
arm fixed underneath the shuttle boxes, and raises the same.
When it is not required to raise the boxes the lever is removed from
contact with the cam by means of a forked lever mounted upon a stud
fixed to a bracket attached to the end frame; the other end of which
lever carries a friction bowl, which is acted on by an incline on the side
of the cam before mentioned. When the first-mentioned lever is thus
removed out of position for raising the boxes it is retained by one end
of a bell-crank lever, the other cnd of which is connected with the

page_text: jacquard apparatus by a cord, and the lever is brought into position
for lifting again by means of the jacquard apparatus acting on the bell-
crank lever and removing the retaining end thereof; the "lifting" lever
is then drawn into position by a spring or equivalent means.
Secondly. Our Invention relates to means or apparatus for stopping
the loom when a shuttle does not "box" properly. Fixed to the back of
the "lay" is a short rod or shaft, from which a finger projects at about
right angles over the shuttle "race." A lever arm and connecting rod
connects the short shaft with a lever mounted on the stop rod and
capable of moving loosely thereon. On this last-mentioned lever is a
pin or stud which works in a slot in the end of a slide rod, on the other
end of which is a friction pulley which is acted on by an incline on
the end frame at every backward motion of the "lay." The action of
the parts raises the projecting finger at the backward movement of the
lay, and it is depressed by a spring at the forward movement; if
however the shuttle fails to "box" properly the finger cannot be
depressed, consequently the lever mounted on the stop rod comes in
contact with the "frog" and knocks off the loom.
Thirdly. Our Invention relates to means for disconnecting the picking
apparatus to allow of two or more picks being made from one end of
the loom, or, if required, to render both picking motions inoperative.
The cam or lever for operating the "picking" shaft is mounted
loosely on its shaft and can be drawn out of position by means of a
lever attached to the end frame of the loom, which is acted on by a
tappit lever connected by a cord with the jacquard apparatus.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Samuel Cooke, William Irving, and
Frederick Howarth in the Great Seal Patent Office on the 15th
January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
SAMUEL COOKE, of the Firm of Messieurs Cooke, Sons, and Law, of
Liversedge, in the County of York, Carpet Manufacturers, and WILLIAM
IRVING, Loom Tuner, and FREDERICK HOWARTH, Mechanic, of the
same Place, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of July, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said James Samuel Cooke, William Irving,
and Frederick Howarth, Her special licence that we, the said James
Samuel Cooke, William Irving, and Frederick Howarth, our executors,
administrators, and assigns, or such others as we, the said James
Samuel Cooke, William Irving, and Frederick Howarth, 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 Ircland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING," upon the condition (amongst others) that we, the
said James Samuel Cooke, William Irving, and Frederick Howarth, our
executors or administrators, by an instrument in writing under 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 2
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said James Samuel Cooke, William
Irving, and Frederick Howarth, 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
statement and accompanying Sheet of Drawing (that is to say) :-
This Invention relates,-
:―

page_text: projecting above the top of the hand rail is a friction pulley or bowl d,
and to the end frame of the loom E is hinged, at a point intermediate
of the ends thereof, a lever F which projects forward over the shuttle
boxes. The projecting end F¹ of this lever is broad and forms an
incline or cam. When in its normal position it is kept clear of the
friction pulley on the top of the lever supporting the shuttle boxes
before mentioned by means of a bell-crank lever G attached likewise to
the end frame, one arm e of which is notched, and by acting on the
back end of the projecting lever the cam or incline end is clevated
above the shuttle boxes.
When it is required to lower the boxes the bell-crank lever, by means
of a cord commencing with the jacquard, is raised and releases the
projecting lever, the end of which falls and comes in contact with the
friction pulley before mentioned, the cam or incline, acting on push-
ing sideway the said friction pulley and supporting lever, removes
the lever at the other side of the boxes and allows them to drop. The
boxes fall from the notches in the levers C on to notches in the levers C¹
and from thence to the next lower notch in the levers C; by this
arrangement the boxes are prevented from falling more than one peg
or box at once. The arrangement is such that when the notches in the
levers Care withdrawn from under the pins those in the levers C' are
brought into position for catching the box and these in their turn are
withdrawn by the spring g.
For raising the boxes we employ a lever H hinged to the end frame,
which is acted upon at about the centre thereof by a cam H¹ mounted
upon a shaft J extending underneath the loom from end to end. This
cam acts on the under side of the said lever, raising the same, and the
unattached end takes into one of a series of notches formed in rigid
arm K fixed underneath the shuttle boxes and raises the same.
When it is not required to raise the boxes the lever is removed from
contact with the cam by means of a clutch or forked lever L mounted
upon a stud fixed to a bracket K attached to the end frame, the other
end of which lever carries a friction bowl L, which is acted on by an
incline m on the side of the cam before mentioned. When the first-
mentioned lever is thus removed out of position for raising the boxes
it is retained by one end of a bell-crank lever M hinged at n, the other
end of which is connected with the. jacquard apparatus by a cord, and

page_text: the lever H is brought into position for lifting again by means of the
jacquard apparatus acting on the bell-crank lever and removing the
retaining end thereof, the "lifting" lever is then drawn into position
by a spring N or equivalent means.
Secondly. Our Invention relates to means or apparatus for stopping
the loom when a shuttle does not "box" properly.
Figs. 4 and 5 represent such portions of the "lay" and other parts
of the loom as are necessary to illustrate our improvements. Fixed to
the back of the lay P is a short rod or shaft Q, from which a finger R
projects at about right angles over the shuttle "race" R¹; a lever
arm S and connecting rod S¹ connects the short shaft with a lever T
mounted on the stop rod U and capable of moving loosely thercon. On
this last-mentioned lever is a pin or stud r attached to the end of a
slide rod V, on the other end of which is a friction pulleys, which is
acted on by an inclinct on the end frame at every backward motion
of the "lay." The action of the parts raises the projecting finger at the
backward movement of the lay, and it is depressed by a spring V₁at
the forward movement; if however the shuttle fails to "box" properly
the finger R cannot be depressed, consequently the lever T mounted on
the stop rod comes in contact with the "frog" W and knocks off the
loom.
Thirdly. Our Invention relates to means for disconnecting the picking
apparatus to allow of two or more picks being made from one end of
the loom, or, if required, to render both packing motions inoperative.
Figs. 6 and 7 are details of low or tappet shaft and picking shaft,
The cam lever or "bowl" 1 for operating the "picking" shaft 2 is
mounted loosely on the said shaft and canbe drawn out of position for
'treading" by means of a lever or clutch fork 3 hinged at 4 to the
bracket 5, which is attached to the end frame of the loom. This clutch
fork is moved to and fro by the cam or eccentric 6 on the stud 7
acting on the clutch fork lever at S. On the stud 7 is a weighted
lever 9, which is connected by cord to the jacquard apparatus; as this
weighted lever is raised the cam acting on the clutch draws the bowl 1
out of position for depressing the lever 10 on the picking shaft 2, and
consequently no pick" or shoot of weft is made from that end of the
loom. The bowl 1 is caused to rotate with the shaft by means of the
pin 11 passing through the boss 12, the pin being of sufficient length
