Year: 1868

page_text: LETTERS PATENT to John Hodgson, of Bradford, Machine Maker,
Henry Bottomley, of Low Moor, Manufacturer, and Ezra Cockroft,
of Odsell Moor, Bradford, all in the County of York, for the In-
PROVISIONAL SPECIFICATION left by the said John Hodgson, Henry
Bottomley, and Ezra Cockroft at the Office of the Commissioners
of Patents, with their Petition, on the 18th December 1868.
We, JOHN HODGSON, of Bradford, Machine Maker, HENRY BOTTOMLEY,
of Low Moor, Manufacturer, and EZRA COCKROFT, of Odsell Moor,
Bradford, all in the County of York, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN APRARATUS EMPLOYED IN WEAVING,"
to be as follows:-
The improvements relate first, to means by which rotary motion may
be given to rotary shuttle boxes containing series of shuttle chambers in
the order desired, with capability for missing or "skipping" one or more
of the shuttle chambers in the selection of the shuttles to be brought

page_text: into usc. For this purpose there are clawker rods to act one on each
side of a stud or peg wheel affixed on the end of the series of shuttle
boxes or chambers to cause them to make partial rotation in either
direction, and each of these clawker rods is connected to one end of a
separate lever, the other end of each of which is connected to a separate
rod extending by preference upwards, and these rods have formed on
each of them a notch or projection adapted to be caught so as to raise
these rods by one end of a lifting lever actuated by tappet or otherwise,
in order to be lifted when they are brought into contact with it during
its rising motion. This lifting lever has a regular motion imparted to
it corresponding with the time for changes of shuttles, and the rods
extending upwards have motion given to them to bring them into
position to be acted on by the lifting lever for the extent of motion
desired by pins of various lengthis, the length of such pins being adapted
to the selection required when acted upon by jacquard plates or
pattern surface. These pins may be either applied to intermediate levers
or to the upper ends of the rods extending upwards. In place of pins
of various lengths levers may be used, each of which is connected to
the jacquard apparatus and capable of being lifted by any one-of two
or more harness cords connected to such levers at distances apart from
the axis of motion of such levers corresponding with the extent of
motion desired to be given thereto to bring the noses or projections into
correct position-for-the-action-of the lifting lever, or the noses or pro-
jections may be placed in position by steps on a swing lever operated
by jacquard acting on studs on bottom levers. The effect may be
.obtained by a chain passing over a wheel on the box, the links being
in part covered by movcable covers.
The improvements relate also to micans for actuating vibratory shuttle
boxes for pick and pick, and to operating the picking motion therefor;
by which simplicity of action is obtained. For this purpose the boxes
at each end of the batten are affixed to the opposite ends of the same
shaft which is carried by the batten, and has affixed on it arms which
by links are connected to levers operated by excentric or other tappets
affixed on the tappet or other shaft. Projections on the sides of these
excentrics or tappets, or otherwise operate fingers or arms on a sliding
rod so as to slide the picking tappets into or out of gear with their cones
or arms to regulate the picking motions.
The method of operating vibratory shuttle boxes is also applicable to

page_text: rotary boxes, but in this case the arms in place of being affixed directly
to the shaft of the boxes are applied to move thereon, and they by
clicks or drivers actuate ratchet wheels or such like means applied to
such shaft. Such shaft also in place of being connected direct to the
boxes may operate them by pinion or other gear.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Hodgson, Henry Bottomley, and Ezra
Cockroft in the Great Seal Patent Office on the 18th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JoпN
HODGSON, of Bradford, Machine Maker, HENRY BOTTOMLEY, of Low
Moor, Manufacturer, and EZRA COCKROFT, of Odsell Moor, Bradford,
all in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of December, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself; Her heirs and succes-
sors, give and grant unto me, the said John Hodgson, Henry Bottomley,
and Ezra Cockroft, Her special licence that we, the said John Hodgson,
Henry Bottomley, and Ezra Cockroft, our executors, administrators, and
assigns, or such others as we, the said John Hodgson, Henry Bottomley,
and Ezra Cockroft, 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, usc, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN APPARATUS EMPLOYED IN WEAVING," upon the condition
(amongst others) that we, the said John Hodgson, Henry Bottomley,
and Ezra Cockroft, 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 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 John Hodgson, on behalf of myself
and the said Henry Bottomley and Ezra Cockroft, do hereby declare

page_text: 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 thereof, that is to say :-
The improvements relate, first, to means by which rotary motion may
be given to rotary shuttle boxes containing series of shuttle chambers in
the order desired with capability for missing or "skipping'
one or more
of the shuttle chambers in the selections of the shuttles to be brought
into use. For this purpose there are clawker rods to act one on each
side of a stud or peg wheel affixed on the end of the series of shuttle
boxes or chambers to cause them to make partial rotation in either
direction, and each of these clawker rods is connected to one end of a
separate lever, the other end of which is connected to a separate rod
extending by preference upwards, and these rods have formed on each of
them a notch or projection adapted to be caught so as to raise these rods
by one end of a lifting lever actuated by tappet or otherwise in order to
be lifted when they are brought into contact with it during its rising
motion. This lifting lever has a regular motion imparted to it corre-
sponding with the time for changes of shuttles, and-the rods extending.
upwards have motion given to them to bring them into position to be
acted on by the lifting lever for the extent of motion desired by pins of
various lengths, the length of such pins being adapted to the selection
required-when-acted-upon by jacquard plates or pattern surface. These
pins may be either applied to intermediate levers or to the upper ends of
the rods extending upwards. In place of pins of various lengths levers
may be used, each of which is connected to the jacquard apparatus
and capable of being lifted by any one of two or more harness cords con-
nected to such levers at distances apart from the axis of motion of such
levers corresponding with the extent of motion desired to be given
thereto to bring the noses or projections into correct position for the
action of the lifting lever; or the noses or projections may be placed in
position by steps on a swing lever operated by jacquard acting on studs
on bottom levers. The effect may be obtained by a chain passing over a
wheel on the box the links being in part covered by moveable covers.
The improvements relate, secondly, to means for actuating vibratory
shuttle boxes for pick and pick, and to operating the picking motion
therefor, by which simplicity of action is obtained. For this purpose the
boxes at each end of the batten are affixed to the opposite ends of the
same shaft which is carried by the batten, and has affixed on it arms

page_text: which by liuks are connected to levers operated by excentric or other
tappets affixed on the tappet or other shaft. Projections on the sides
of these eccentrics or tappets, or otherwise, operate fingers or arms on
a sliding rcd so as to slide the picking tappets into or out of gear
with their cones or arms to regulate the picking motions.
us in carrying the same into effect.
DESCRIPTION OF TILE, DRAWINGS.
Figure 1 shows an outline, end view of a portion of a loom with the
first part of our inprovements applied thereto; Figure 2 shows a back
view of some of the parts; and Figure 3 other portious in detail.
In each of the Figures the same letters are employed to indicate
corresponding parts; a, a, represents in outline a portion of the curl
framing of a loom; is the main or crank axis; and' c the cam or
tappet shaft receiving motion from the main or crank axis by means of
a tooth wheel c indicated by red dotted lines, and which wheel receives
motion from a tooth whical & also indicated by red dotted lines on the
main or crank shaft b, as is well understood; d and e are clawker rods
which are each furnished at their upper ends with teeth d', e, adapted'
when drawn upon to act on the teeth of a stud or peg wheelf affixed to
the axis of the series of box chambers y so as to cause them to make a
partial rotation in either direction, depending on which of those clawker.
rods is for the time acted upon. The clawker rod d is at its lower end
connected with capability of adjustment, and by pin joint to one end
of the lever d³ which is capable of moving on the stud d, and at its
other end by pin joint . The lever d³ is connected to the rod d, which
is constantly drawn on at its lower end by a spring d, with a tendency
to draw the upper end of the rod d towards the back of the loom and
against the projection or knife edge ' carried by the lever h, which lever
is a lifting lever turning on a fixed stud h and carrying a truck or
roller to run on the cam or tappet affixed on the cam or tappet
shaft c, and which in its rotation gives the required lifting motion to the
lifting lever h. The rod do is formed with a notch or other suitable
5 projection adapted when acted upon by the knife edge ' in the lifting
of that end of the lever h to cause the rod d to be raised, and in doing
so to cause the rod d by its teeth d¹ to effect a partial rotation of the

page_text: series of boxes or shuttle chambers in one direction. A corresponding
step-by-step partial rotary motion of the series of shuttle chambers in
the opposite direction is effected by the clawker rod e, which is connected
to a similar lever es, which is also similarly connected to the rod e
having a notch or tooth es. As shown the parts are capable of effecting
a change of position of the boxes equal to that from one chamber to the
next, or so as to skip one of them when desired, but this may be varied
to the skipping of other numbers. The variations in the direction and
extent of motion to the boxes as shown are effected in the following
manner-The lifting motion to the outer end of the lifting lever is
adapted to raise the rods d, e, when acted upon by it a distance equal
to that of two shuttle chambers, and the distance effected at any one
time depends on the position of the notches or projections d, e, of the
lifting rods de ande for the time in relation to the knife edge h'. When
not otherwise acted upon the tendency of the rods d and e" is upwards
by reason of the springs and e" acting on the under sides of the hinder
ends of those levers and e, and they are moved in the opposite
direction by means of the levers d, e, each of which is furnished with
two pins d, e, of different lengths adapted to cause the levers (
and e to push the rods or e' downwards a distance suitable for the
correct action thereon of the blade in its rising motion, when one of
those pins is acted upon by a card or plate passing over the card
cylinder i, the other of the pins of those levers do and eo being for-the
time allowed to pass through holes in a card or plate of a chain of
pattern surfaces. The card or pattern cylinder i is supported to turn on
a stud projecting from one end of the lever, which like the
levers d, e, is supported to turn on the stationary stud, and at its
other end it is by pin joint connected to one end of the link , which at
its other end turns on and is actuated by the crank pin affixed with
capability of adjustment to the face of the pinion . The pinion turns
upon a fixed stud 7, and the teeth of it are taken into by the teeth of a
pinion affixed on the crank axis b. j is a clawker the end of which by
coming against studs on the end of the cylinder i effects its partial
rotation at cach downward motion of that end of the lever, and is
a squaring lever for squaring the cylinder i. The clawker j and squaring
lever are cach supported to turn on the fixed stud j¹.
Pins of different lengths for effecting the changes in the extent of
motion of the series of shuttle chambers may be either applied to
intermediate levers, as explained, or they may be applied direct to the

page_text: rods de and, and in place of pins levers may be used, connected to
two or more jacquard or harness cords, such jacquard or harness cords
being connected to their levers at varying distances from their axis
of motion so as thereby to effect the desired variations in distance of
traverse of the series of boxes.
Figure 4 shows an end view of parts of a loom with a modification of
this portion of thic Invention applied to it.
Figure 5 shows one of the parts separately. In this case each of the
levers d, e, is formed with two notches or steps de, **, and e, ex,
and they are capable of hoing moved into position for the knife edge
in the rising of the lever taking one or the other of them by means
of the levers and m, which are supported with capability of turning
on the fixed stud The lower end of the lever bears against
the lever do, whilst its other end is by pin joint connected to one
ond of the link, the other end of which is by pin joint connected to
a levor which turns on the fixed stud, and at its other ond carries
a pair of pins "of different lengths adapted to the different extent of
motion required at different times to be given to its lever do so as
to bring one or the other of the notches or steps d, e, into position
to be acted upon by the knife edge h, and thereby effect the desired
extent of motion to the shuttle box. The lover m in like manner is
by a similar link connected to a lever e with similar pins for acting
in like manner on the lever and actuating the series of boxes in the
opposite direction; springs d' draw the levers d and e" against the lovers
and m. The change of direction of motion and the extent of motion
at any time effected upon the shuttle boxes may also be obtained by
means of a chain flat-linked or ladder-like, the links of which take
on to the horns or teeth of a wheel applied on the end of the series
of shuttle boxes, so that when the chain is drawn upon in either direction
by clawker or looked ended levers it will give a corresponding motion to
the series of chambers, which motion may be arranged to be continuous,
but intercepted for the order or extent of action desired by plates
capable of sliding on the chain so as to prevent the pulling action of
the clawkers or hooks for the desired selection; such plates may be
carried and actuated by rods similar to those herein referred to for
giving motion to series of shuttle chambers, and may be actuated by the
jacquard or pattern surface.
Figure 6 shows a portion of an end view, and Figure 7 a portion

page_text: of a front view of a loom with improvements applied thereto, according
to the second head of the Invention, for actuating vibratory shuttle
boxes for pick and pick." n¹, n', are two shuttle chambers in
one rocking frame or box n, which is affixed to the shaft n, so
as to rock with that shaft, and this shaft 2 is supported partially
to rotate or rock in bearings carried by the batten, and it passes
through the batten to the opposite end, where there is also applied
to it a similar box with a similar pair of shuttle chambers, so that
when motion is given to the shaft * similar motion is simultaneously
Partial
given thereby to the boxes at both ends of the batten.
rotary or rocking motion is given to the shaft 2 in either direction
by means of cams or tappets o, p, affixed on the cam or tappet shaft c
acting on the levers o¹ and p', which are both supported to rock on
the fixed stud c; one and of the lever is horne with its nose o
against the cam or tappet o, whilst its other end is by the connecting
link o connected to an arm of affixed to the shaft or axis n. The
nose of the lever is in like manner borne against the cam or
tappet p, whilst the other end of that lever is by a connecting rod. p
connected to another arm p" affixed to the axis n. By these means
the desired motions are given to the boxes alternately in opposite
directions. This method of operating vibratory shuttle boxes is also
applicable to rotary boxes, but in this case the arms in place of being
affixed directly to the shaft of the boxes are applied to move thercon,
and they by clicks or drivers actuate ratchet wheels or such like means
applied to such shaft. Such shaft also in place of being connected
direct to the boxes may operate them by pinion or other gear. The
pickers are drawn upon at each end of the loom by means of a strap q,
one end of which is connected to the picker and the other end to the
outer end of the arm affixed to the socket 7, which turns upon a
fixed stud q, and is drawn upon by the spring q'. In place of check
straps there are springs r by preference formed of india-rubber, vulcanized
or prepared, one end of each of which is counccted to a standard from
the framing of the batten, whilst the other end of it is connected to a
strap which is formed with a hole through it to slide on the picker
rod within the piece of bent leather 1.
Figure S shows by a back view of parts of a loom an arrangement
for operating the picking tappets so as to move them alternately into
position for acting on the picking cones. Figures 9 and 10 show some
of the parts separately. s, s, are the picking tappets, each of which is

page_text: capable of sliding on the cam or tappet shaft c, and they are each of
them provided with studs s¹, s, to slide in holes or sockets provided for
them in wheels &, which are affixed to the cam or tappet shaft c, or
the tappets 8, 8, and their wheels & may be connected together to slide
on other clutch connections, so that whilst the tappets 8, 8, are capable
of sliding on the shaft c they may be caused to rotate with that shaft in
its rotary motion. When the picking tappets are slided out of the way
of the picking cones or arms those cones or arms 2 simply rest on the
conically formed periphery of the wheels 8. Each of the tappets 8, 8, is
formed with a neck &, which is embraced by a fork st, and these forks &*
are affixed with capability of adjustment to the sliding rod s³, which is
capable of sliding to and fro in the stationary bearings 8", and it is
actuated so as to cause the forks to move the tappets alternately into
and out of position by means of the cam s'affixed to the short axis &³,
which is capable of revolving freely in stationary bearings, and has
affixed on it the pinion &", the teeth of which are taken into by the teeth
of the pinion to affixed on the cam or tappet shaft c.
The cam 7

horns of the star wheel a will hold that steadily until in the rotation of
the wheel one or the other of its studs comes between the horns of
the wheel, when a partial rotation will be given to the wheel u. The
