Year: 1871

page_text: LETTERS PATENT to George Hodgson, of Bradford, in the County of
York, Machine Maker, and James Broadley, of Heaton, near the
said Bradford, Mechanic, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 15th September 1871, and dated the 20th March 1871.
PROVISIONAL SPECIFICATION left by the said George Hodgson and
James Broadley at the Office of the Commissioners of Patents, with
their Petition, on the 20th March 1871.
We, GEORGE HODGSON, of Bradford, in the County of York, Machine
Maker, and JAMES BROADLEY, of Heaton, near the said Bradford,
Mechanic, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The improvements relate to means for moving the boxes in order to
effect changes in the order of selection of the shuttles when using
shifting boxes. For this purpose a forked rod operates each series of

page_text: boxes, there being a catch to the upper end of each fork, one to act on
sheds to pull the boxes in one direction, and the other in the opposite
direction. The lower end of each of these forked rods is connected to
an arm from an axis which is provided with another arm and a catch
rod capable of being operated by a broken-backed lever regulated by
pattern surface. The forked rods are borne in one direction by springs,
and in the opposite direction by arms from a shaft carried by the going
part, and which shaft is provided with another arm in position to be
caught or missed by a catch lever regulated by pattern surface.
The improvements also relate when employing rocking shuttle boxes
to means for effecting changes of position of such boxes.
In carrying out this part of the improvements there are short rocking
levers, one for each box. Each of these rocking levers is provided with
studs, one on each side of its axis of motion, and either of these studs is
capable of being acted upon by one of a pair of hooks from a forked
pendant rod. These forked pendant rods hang by pin joint from a
"broken-backed "lever operated by tappet motion, and they are borne
-in one direction by springs, so as to be in position to catch on to one
of the studs of their rocking levers, and they are moved into position
to catch on to the other by studs or bowls capable of being shifted as
desired in a wheel or plate, or by tappets or other pattern surface. The
rocking levers are each connected at one end to lever arms, one for each
rocking box. In place of employing two rocking arms one may be
employed, and in place of the forked rods being actuated by a lever
moved by a tappet, such may be actuated from jacquard or other pattern
surface. The connection from the lever arms to give motion to the
rocking boxes may be to a pin in a plate turning on a centre of motion,
and formed with an inclined curved slotted groove to receive the bowl
of a pin from the axis of each box, by which whilst in the movement of
the plate on its centre the desired movement to the boxes will be
obtained, they will be held steadily in the position selected.
The improvements also relate to means for operating the heddles for
changes of shedding.
In carrying out this part of the improvements the arced jacks or
lifting levers which receive the cords from the heddles are formed pro-
gressively, longer in their radial line from the front to the back, so as
thereby to obtain an even shed. Each pair of the arms from these

page_text: radial jacks or lifting levers are connected together by links, in the
ordinary way, but they are also connected to a pair of hooked rods, and
these hooked rods are capable of being operated by lifters selected by
pattern surface, so as to be brought into position to be caught and drawn
upon by moving blades, and such as are selected are there held for a
time by other blades, which may be stationary. The moving blades are
for convenience applied to the opposite ends or parts of a rocking lever,
or they may be slided. These moving blades also act to release the
hooked ends from the holders; or in place of fixed holders moveable
holders may be employed, operated by pattern surfaces, with one double
hooked rod to each pair. In place of employing pairs of hooked rods
a single rod with several hooks or catches on it may be employed to
each heddles, with moveable V or other catches to act on these rods, and
moveable stops operated by pattern surface, or one of the moveable
rods may serve as the holding rod. The hooked rods may be connected
to lifting cords or bands which pass over guide pullies, and the hooks
operated by catches or sliding bars operated by pinion and racks, or
other suitable means, the selection being by pattern surface.
The improvements also relate to means for drawing the heddles down-
wards, or in a direction opposite to that by which they are drawn by the
action of the pattern surface. For this purpose in place of the ordinary
springs pulling direct on such heddles the heddles are each connected to
the outer ends of a pair of levers, which are formed with arms or pro-
jections, to which the springs are attached, such springs drawing from a
point behind the axis of motion of the levers, and at an angle to the
arms thereof, by which, with the same power of draft on the heddles,
the springs will be but slightly drawn upon, and will thereby retain
their tension for a much longer time, whilst ease will be secured, and
less power required in working the loom.
Also the improvements relate to means for operating the card cylinders
or other pattern surface.
In carrying out this part of the Invention the clawker or driver for
taking into the catch wheel to cause the rotation of the card cylinder is
formed with another arm or projection capable of being operated by
studs or projections, or recesses from or in another wheel or cylinder
having a catch wheel applied to it, operated by a clawker from an extra
lever operated by the card cylinder or pattern surface; by these means

page_text: '
a saving in the repeat of the pattern surface will be effected for weaving
long patterns, such as dress fabrics with flounces, robes, and other
fabrics.
The improvements also relate to means for acting on the stop motion
to stop the loom when the shuttle fails properly to enter its chamber in
using sliding, rotary, or rocking boxes. -
In carrying out this part of the Invention a channel is formed in the
surface of the boxes to receive an arm from the stop rod. The end of
this arm is in position to be acted upon by the shuttle when the shuttle
properly boxes, and in so doing to cause the stop rod to turn and lift its
lever arm from the frog. In the event of a shuttle not properly boxing,
so as to act on the end of this arm, the stop motion will stop the loom.
A bowl or projection from an arm from the stop rod travels on a plate
form to hold the arm intended to act on the shuttle out of the way
of
the shuttle until the shuttle should have been properly boxed; or this
may be effected by a tappet and lever motion.
The improvements also relate to means for effecting pick and pick.
For this purpose there is applied to cach picking axis a pair of combs at
right angles, or thereabouts, one to the other, and connected together so
as to be capable of turning on a common centre of motion carried
by such picking axis, so that either may be brought into position to be
acted on by a picking nose of a picking tappet. The turning of these
combs or arm on their common centre is effected by a rod and lever
operated by the jacquard or pattern surface. The picking noses of each
picking tappet are not in the same line, so that one may in its rotation
act on one of the combs or arms when that is brought into position for
that purpose, and the other on the other comb or arm when that is
brought into position for that purpose.
The improvements also relate to means for holding the warp beam
from giving off warp during the beat up. For this purpose we employ
several clawkers or catches to act in the teeth of a wheel on the axis of
the warp beam, and we operate these clawkers or catches by excentric,
or such like means from the crank or other suitable shaft, so as to cause
them to operate in holding at the time the beat up takes place.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Hodgson and James Broadley in the Great
Scal Patent Office on the 18th September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HODGSON, of Bradford, in the County of York, Machine Maker, and
JAMES BROADLEY, of Heaton, near the said Bradford, Mechanic, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of March, in the year of
our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said George Hodgson and James Broadley, Her
special licence that we, the said George Hodgson and James Broadley,
our executors, administrators, and assigns, or such others as we, the said
George Hodgson and James Broadley, 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 Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," upon
the condition (amongst others) that we, the said George Hodgson and
James Broadley, our executors or administrators, by an instrument in
writing under our, or their hands and seals, or under the hand and seal
of one of us, or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the sainc 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 we, the said George Hodgson and James
Broadley, 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 thereof, that is
to say:
The improvements relate, firstly, to means for moving the boxes in
order to effect changes in the order of selection of the shuttles when
using shifting boxes. For this purpose a forked rod operates each series
of boxes, there being a catch to the upper end of each fork, one to act

page_text: on studs to pull the boxes in one direction, and the other in the opposite
direction. The lower end of each of these forked rods is connected to
an arm from an axis, which is provided with another arm and a catch
rod capable of being operated by a "broken-backed" lever regulated
by pattern surface. The forked rods are borne in one direction by
springs, and in the opposite direction by arms from a shaft carried
by the going part, and which shaft is provided with another arm in
position to be caught or missed by a catch lever regulated by pattern
surface.
Secondly. The improvements relate, when employing rocking shuttle
boxes, to means for effecting changes of position of such boxes.
In carrying out this part of the improvements there are short rocking
levers, one for each box. Each of these rocking levers is provided with
studs, one on each side of its axis of motion, and either.of these studs
is capable of being acted upon by one of a pair of hooks from a forked
pendant rod. These forked pendant rods hang by pin joint from a
broken-backed" lever, operated by tappet motion, and they are borne
in one direction by springs, so as to be in position to catch on to one
of the studs of their rocking levers, and they are moved into position
to catch on to the other by studs or bowls capable of being shifted,
as desired, in a wheel or plate, or by tappets, or other pattern surface.
The rocking levers are each connected at one end to lever arms, one
for cach rocking box. The connection from the lever arms to give
motion to the rocking boxes may be to a pin in a plate turning on a
centre of motion, and formed with an inclined curved slotted groove
to receive the bowl of a pin from the axis of each box, by which
whilst in the movement of the plate on its centre the desired move-
ment to the boxes will be obtained, they will be held steadily in the
position selected.
Thirdly. The improvements relate to means for operating the heddles
for changes of shedding.
In carrying out this part of the improvements the arced jacks or
lifting levers which receive the cords from the heddles are formed
progressively longer in their radial line from the front to the back, so
as thereby to obtain an even shed. Each pair of the arms from these
radial jacks or lifting levers are connected together by links in the
ordinary way, but they are also connected to a pair of hooked rods, and
these hooked rods are capable of being operated by lifters selected by

page_text: pattern surface, so as to be brought into position to be caught and
drawn upon by moving blades, and such as are selected are there held
for a time by other blades, which may be stationary. The moving
blades are, for convenience, applied to the opposite ends or parts of a
rocking lever, or they may be slided. These moving blades also act
to release the hooked rods from the holders; or in place of fixed holders
moveable holders may be employed, operated by pattern surfaces with
one double hooked rod to each pair. In place of employing pairs of
hooked rods a single rod with several hooks or catches on it may be
employed to each heddle with moveable V or other catches to act on;
these rods and moveable stops operated by pattern surface, or one of the
moveable rods may serve as the holding rod. The hooked rods may be
connected to lifting cords or bands which pass over guide pulleys, and
the hooks operated by pinion and racks or other suitable means, the
selection being by pattern surface.
Fourthly. The improvements relate to means for drawing the heddles
downwards or in a direction opposite to that by which they are drawn
by the action of the pattern surface. For this purpose in place of the
ordinary springs pulling direct on such heddles the heddles are each
connected to the outer end of a pair of levers, which are formed with
arms or projections, to which the springs are attached, such springs
drawing from a point behind the axis of motion of the levers and at an
angle to the arms thereof, by which with the same power of draft on the
heddles the springs will be but slightly drawn upon, and will thereby
retain their tension for a much longer time, whilst case will be secured
and less power required in working the loom.
Fifthly. The improvements relate to means for operating the cards,
cylinders, or other pattern surface.
In carrying out this part of the Invention the clawker or driver for
taking into the catch wheel to cause the rotation of the card cylinder
is formed with another arm or projection capable of being operated by
studs, or projections, or recesses, from or in another wheel or cylinder
having a catch wheel applied to it, operated by a clawker from an extra
lever operated by the card cylinder or pattern surface. By these means
a saving in the repeat of the pattern surface will be effected for
weaving long patterns, such as dress fabrics with flounces, robes, and
other fabrics.

page_text: Sixthly. The improvements relate to means for acting on the stop
motion to stop the loom when the shuttle fails properly to enter its
chamber in using sliding rotary or rocking boxes.
In carrying out this part of the Invention a channel is formed in
the surface of the boxes to receive an arm from the stop rod. The end
of this arm is in position to be acted upon by the shuttle when the
shuttle properly boxes, and in so doing to cause the stop rod to turn
and lift its lever arm from the frog. In the event of a shuttle not
properly boxing so as to act on the end of this arm the stop motion
will stop the loom. A bowl or projection from an arm from the stop
rod travels on a plate formed to hold the arm intended to act on the
shuttle out of the way of the shuttle until the shuttle should have
been properly boxed. Or this may be effected by a tappet and lever
motion.
Seventhly. The improvements relate to means for effecting pick and
pick. For this purpose there is applied to each picking axis a pair
of cones at right angles or thereabouts one to the other, and connected
together so as to be capable of turning on a common centre of motion.
carried by such picking axis so that either may be brought into position
to be acted on by a picking nose of a picking tappet. The turning of
these cones or arms on their common centre is effected by a rod and
lever operated by the jacquard or pattern surface. The picking noses.
of each picking tappet are not in the same line, so that one may in its
rotation act on one of the cones or arms when that is brought into
position for that purpose, and the other on the other cone or arm when
that is brought into position for that purpose.
Eighthly. The improvements relate to means for holding the warp
beam from giving off warp during the beat up. For this purpose we
employ several clawkers or catches to act in the teeth of a wheel on
the axis of the warp beam, and we operate these clawkers or catches
by eccentric or such like means from the crank or other suitable
shaft, so as to cause them to operate in holding at the time the beat up
takes place.
But that the Invention may be fully understood we will, by the aid
of the accompanying Drawings, proceed to describe means pursued by us
in carrying the same into effect.

page_text: DESCRIPTION
Figure 1 shews an end view of parts of a loom with improvements
applied to it according to the first head of the Invention. a is the
forked rod, the forked ends a¹ of which are each formed with a catch a²,
adapted when brought into contact with any one of the studs ¹ in a
disc b connected to a series of shifting boxes and drawn in a downward
direction to give partial rotation to such series of boxes or shuttle
chambers in one or the other direction, depending on which of the
ends a¹ for the time is brought into operation. The lower end of this
forked rod a is connected by pin joint a³ to one end of the lever c, which
is supported to turn upon the axis of motion c¹, and at its other end is
connected by pin joint c² to the catch rod d, which by its catch d¹ is
capable of being acted upon and lifted by the Ve¹ of the "broken-
backed" lever e, which turns upon the stud e³, and is operated by
suitable tappets on the tappet shaft f. The catch d¹ of the catch rod d
is borne by a spring d² towards the V e¹, and it is moved in the opposite
direction so as to be free of that \ by means of the inverted L lever g,
the lower end of which is provided with pins g¹, g¹, to embrace the
catch lever d. The inverted L lever g turns upon a stud g³, and at its
other end it carries a piụ g³ by which it may be lifted by cards or
pattern surface on the cylinder / or by other suitable pattern surface.
The upper end of the forked rod a is borne in one direction by a
spring a, and it is acted upon with a tendency to bear it in the opposite
direction by the projection of the lever arm from the shaft or
axis, which is supported to turn in a bearing affixed to the lay sword.
Upon this axis is also applied another arm 23 which is acted upon
by a spring, with a tendency to cause the stud i at the upper end of
the arm to bear against the forked rod a and by the increased strength
of the spring i to overcome the effect of the spring at. The stud i on
the arm ¹ is withdrawn from bearing against the forked rod a to allow
of the action of the spring a thereon when desired in the forward motion
of the batten by means of the hook j¹ formed on one end of the rod j,
catching on to the stud from the arm i³. The other end of the
rodj is capable of turning on a stud j² carried by the main framing.
The arm is lifted out of the way of the stud by means of the link j³
one end of which is by pin joint connected to the rod j, and the other to
a lever which by a suitable stud is operated by the card cylinder or by
other suitable pattern surface.

page_text: Figures 2, 3, and 4 show two opposite ends and a back view of parts
of a loom with the second portion of our Invention applied to it. Each
end of the loom is shewn provided with a rocking box k for two
chambers, and the object of the improvements is to bring either chamber
of either box in a line with the race at pleasure; and this is effected by
the action upon the rocking levers and m, each of which is provided
with studs capable of being acted upon by the hooked ends of pendant
rods. The rocking lever is provided with studs 1, 1³, which may be
acted upon by one or the other of the hooked ends of the forked rod
when that is raised by the raising of the broken-backed lever n to which
the upper end of the forked rod is connected. The pendant forked
rod is drawn towards the stud & by a spring 1, and it is moved in the
opposite direction so as to be in a position to take on to the stud l¹ by
the action of bowls 7 in a wheel o. The broken-backed " lever n turns
upon a fixed stud n¹, and it is operated by a tappet n² on the tappet shaft,
as is well understood. The stud also serves as a means of connection
to one end of the lever, which is supported simply to turn upon the
spindle m, and at its other end this lever is connected by pin joint
to the lower end of the rod P, the upper end of which is connected by
pin joint to an arm from the plate ", with capability for the adjust-
ment of the position of the pin ♬ in that arm. The plate 7" is supported
with capability of turning on the stud 11 carried by the shuttle box
frame, and it is formed with a curved slotted opening to receive a
bowl upon an arm 11 from the shuttle box % at that end of the loom.
By these means any motion given to the rocking lever will be com-
municated to the box k at that end of the loom. By the use of the
inclined curved slot 7¹³ the box will be held steadily after each movement
in the position selected. The rocking lever m is provided with corre
sponding studs m¹, m³, and the stud m³ serves as a means of connection
to the outer end of an arm m³ affixed to the shaft or axis m*, which is
supported to turn in bearings carried by the main framing, and at the
other end has affixed to it another arm m³, the outer end of which is, by
pin joint mo, connected to the lower end of the connecting rod m², and
the upper end of this connecting rod m² is, by pin joint m³, connected to
an arm from the plate m³, which plate is supported to turn on a stud m³
carried by the framing of the shuttle box at that end of the loom, whilst
the plate m is formed with an inclined curved slot mo corresponding
with the slot 13 in the plate
projecting from the shuttle box
to receive a bowl m" from an arm
at that end of the loom. The rocking

page_text: lever m is capable of being operated by the hooked ends of a forked
pendant rod m similar to the forked pendant rod ', and which, like the
forked pendant rod 1, is borne in one direction by a spring, whilst it is
borne in the opposite direction according to the selection desired by
studs on the face of the wheel o. In place of employing two rocking
| levers l, m, one may be employed; and in place of the forked rods * and
m being actuated by a lever n moved by a tappet such may be actuated
from jacquard or other pattern surface.
Figure 5 shews a front view, and Figure 6 an end view of a loom, with
part arranged according to the third head of the Invention.
P, P, represent one pair of arced jacks or lifting levers, to which are
connected the cords for supporting heddles. These arced jacks or lifting
levers p to the respective leaves of heddles are progressively formed
longer from their axis of motion p¹ to the segment or are p² as they
recede from the front to the back; thus the radial lines from p¹ to p² of
the second pair of these levers p would be longer in the second pair
from the front than in the first pair, and longer still in the third pair
than in the second, and so on; and the extent of variation should be
such as to open the warps to progressively increasing distances towards
the back of the loom, and thereby to obtain an even shed. The two
arced jacks or lifting levers p forming a pair are connected together by a
link pin the ordinary way, and they are operated for the required
movements to them, and the healds carried thereby in the order desired
by cach pair being provided with a pair of rods p*, each of which is
formed with two notches or hooks p³, 2°. The object of the hooks p³ is,
that when those hooks are brought into position they may be caught and
moved by blades caused to move the distance desired, and in so doing
place the hooks p³ in position for those rods p' being held for a time by
suitable holders. According to the arrangement shewn each rod på
passes through a slot formed for it in a separate slide p', and these
slides are each capable of sliding vertically in guides 28, 29, whilst
their lower ends p³ are formed to be capable of being acted upon by
cards or other pattern surfaces carried by a card cylinder p10, as motion
is given to that cylinder by its being affixed to one end of a lever
arm p from the axis p, whilst the other end of the lever arm p¹¹ is
connected to one end of the eccentric rod p¹³, which rod p¹s is actuated
by the eccentric p¹ on the crank shaft; but this method of selection may
be varied. The moving blades p¹, as shown, are applied to the opposite

page_text: ends of a lever or pair of arms p¹ formed on or affixed to the shaft or
axis p, which axis is supported so as to be capable of freely turning
in bearings carried by the framing of the loom. Upon the axis p
is affixed another arm p¹8, by motion to which a rocking motion is
obtained to the blades p¹; and this motion to the arm p¹s is obtained, as
shewn, by its being connected by adjustable stud connection p¹º to one
end of the rod p, the other end of which is connected to and actuated
by the stud p¹ projecting from the pinion p, which is supported to turn
on the fixed stud p³, and the teeth of which take into the teeth of a
pinion p affixed on the crank shaft. p are stationary holding blades
for acting on the hooks p to hold the rods after each selection. Each
rod p* is released from its holding-on blades p" in the next movement in
that direction of one of the moving blades 2015 moving one or the other
of the pair a distance to release the one held from its holding of a
holding blade p³, whilst it is not held upwards by the selecting instru-
ments p. In place of the fixed or stationary holders p25 holders may be
applied having motion given to them by jacquard or other suitable
pattern surface.
It will also be readily understood that in place of the hooked rods
being arranged in pairs, hooked rods may be employed to operate with
like effect singly by each of such single rods being formed with several
hooks or catches, and with moveable V or other catches to act on these
hooks together with moveable holding stops, all operated by jacquard or
pattern surface or one of the moveable catches may act as a holder.
Figure 7 shows by a diagram another modification of parts for
operating on the heddles, under this third bead of the Invention. In
this case the toothed rods p' are by pin joints p connected in pairs to
sliding rods p, and these rods p" are supported to slide in stationary
guides p28, so that the inner ends of them may be connected each to a
pair of cords or bands p", which pass over guide pulleys 2030 to their
respective heddle frames p³. The guide pulleys p³ are supported as is
usual to turn on fixed studs p³. The hooks p* are in this case also
lifted as required into position to be caught and drawn upon by sliding
rods p through which they pass, and which sliding rods are actuated
for the desired selection by jacquard or other suitable pattern surface.
The moving and holding catches pts are applied to sliding bars p³¹ which
are simultaneously moved in opposite directions by being connected
together by rack and pinion or by other suitable means.

page_text: This Figure 7 also shews the fourth part of the Invention applied.
Each leaf of heddles p¹ being connected to the outer ends of two levers q
which turn on separate axes or studs q', and each of these levers q is
formed with an arm q² to receive one end of a spring q³, the other end
of which is connected to a stud q*.
We will now describe the fifth part of our improvements an illus-
tration of which is shewn by side and edge views at Figures 8 and 9.
In this case represents a card cylinder, which is supported so as to be
capable of turning on the stud projecting from the vertical bar 7,
and this bar is guided with capability for up-and-down motion in
bearings carried by the main framing, so that the necessary movement
may be imparted to the card cylinder 7; 23³ is the clawker hung from a
fixed stud, so that in the up and down movement of the card cylinder
the tooth of the clawker 7 by taking into the ratchet teeth 1ª of the
card cylinder may cause the rotation of the card cylinder for change
of card or other pattern surface as is well understood. This clawker r³,
or it may be a driver, according to our improvements, is formed with an
arm in position to be acted upon by a stud or projection r³, or any
number of them applied to or formed on the ratchet wheels, the teeth
of which are taken into by a clawker 10, or it may be a driver suspended
by pin joint from the outer end of the lever 12, which is supported
at its other end with facility for turning on a fixed stud ¹³ carried by
the main framing and which carries an adjustable pin
upon by a card or pattern surface carried by the cylinder ».
t
to be acted
We will now describe the sixth part of our Invention, which is
represented by Figure 10, where s shews by a sectional view the outline
of a rocking box with two shuttle chambers &¹, s¹, and a channel s²
formed in its surface to admit of the end of the arm passing therein,
so as to act against a shuttle in either of those chambers which may for
the time be brought into a line with the race of the loom. The arm t
is affixed to the stop rod t, to which is applied another arm to carrying
a truck or bowl t' to run upon the upper surface of the casting in the
forward movement of the batten when the shuttle does not properly
enter its box and act on the end of the arm t, so as to keep the arm (³
raised. is the frog. The Drawing shews the parts in the position
when a chamber s¹ is ready to receive a shuttle in the ordinary course of
weaving. If the shuttle fails to properly box the truck or bowl t¹ will
by following the course of the upper surface of the stationary casting ("

page_text: cause the point 13 of the arm 3 to come against the step of the frog
and effect the stoppage of the loom. If the shuttle properly enters its
box the end 8 of the arm 3 will rest against the shuttle to raise the
bowl from the casting to, and the point t of the "frog" so that the
beat up may properly take place. Although we have only shown this
part of the Invention applied to a rocking box of two chambers, it is
also applicable to other rocking, sliding, or rotary boxes.
Figures 11 and 12 shew by a plan and back views a portion of a
loom with the seventh part of our improvements applied to it; u and u¹,
are a pair of cones applied at right angles, the one to the other, and
carried by the arm u³, so as to turn upon an axis ³ carried by the
picking axis u. The arm u² is by a link u³ connected to a suitable lever
operated by jacquard or other pattern surface, so as to bring either of
the cones u or u¹ into position for being acted upon by a nose of a
picking tappet v, and in carrying out this part of the improvements,
the picking tappets are each formed with two noses v₁ and v², the nose v¹
being that for acting on the cone u and the nose v³, that for acting on
the conc u¹, so as to change the order of picking as desired.
Figure 13 is a diagram to illustrate the eighth part of our Invention;
w is the warp beam upon which is applied the ratchet wheel w¹, the
teeth of which are capable of being taken into by either of the catches x
applied to the eccentrix x¹ affixed on the crank or other suitable shaft y,
in order to effect a better holding of the warp beam and prevent the
giving off of warp during the beat up.
Having thus described our improvements we would have it under-
stood that we do not confine ourselves to the precise details as shewn
and described, as variations may be made therein without departing
from the peculiar character of our Invention; but what we do claim is,—
First. The adaptation or combination of means for effecting changes
in the order of selection of shuttles when employing shifting shuttle
